本申请涉及通信技术领域，尤其涉及一种搜网方法、装置、终端设备及存储介质。The present application relates to the technical field of communications, and in particular to a method, device, terminal equipment and storage medium for searching a network.
背景技术Background technique
目前，在进行公共陆地移动网络(Public Land Mobile Network，PLMN)类别选网时，会选择PLMN优先级更高的网络进行驻留。Currently, when selecting a public land mobile network (Public Land Mobile Network, PLMN) type network, a network with a higher PLMN priority will be selected for camping.
然而，根据PLMN类别的优先级确定PLMN进行搜网，可能会选择一个拥塞严重的小区进行驻留，从而在进行注册或发起业务时导致统一接入控制(unified access barring，UAC)检查禁止，此时只能等待UAC相关定时器超时，超时后进行重试，但重试时依然有可能出现UAC检查继续禁止，如此重复多次，最终导致终端设备一直无法入网，无法进行注册或发起业务。However, according to the priority of the PLMN category, it is determined that the PLMN performs network search, and a cell with serious congestion may be selected for camping, thereby causing unified access control (unified access barring, UAC) checks to be prohibited when registering or initiating services. You can only wait for the UAC-related timer to expire, and retry after the timeout. However, the UAC check may continue to be prohibited during the retry. Repeating this many times will eventually cause the terminal device to be unable to access the network, register or initiate services.

In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.
下面首先对本发明的权利要求书和说明书中涉及的一些名词或者术语进行解释说明。Firstly, some nouns or terms involved in the claims and description of the present invention will be explained below.
1、公共陆地移动网络：由政府或它所批准的经营者，为公众提供陆地移动通信业务目的而建立和经营的网络。目前，PLMN＝移动国家码(Mobile Country Code，MCC)+移动网络号码(Mobile Network Code，MNC)。例如：中国为460，厂商A为00，厂商B为01，则中国的厂商A的PLMN为46000，中国的厂商B的PLMN为460001。1. Public land mobile network: a network established and operated by the government or its approved operators for the purpose of providing land mobile communication services for the public. Currently, PLMN=Mobile Country Code (Mobile Country Code, MCC)+Mobile Network Number (Mobile Network Code, MNC). For example: China is 460, manufacturer A is 00, and manufacturer B is 01, then the PLMN of Chinese manufacturer A is 46000, and the PLMN of Chinese manufacturer B is 460001.
PLMN根据属性的不同，可以包括以下几种：According to different attributes, PLMN can include the following types:
(1)注册公用陆地移动网络(Registered Public Land Mobile Network，RPLMN)：其为终端在上次关机或脱网前登记上的PLMN。(1) Registered Public Land Mobile Network (RPLMN): It is the PLMN registered by the terminal before it was shut down or disconnected from the network last time.
(2)归属公用陆地移动网络(Home Public Land Mobile Network，，HPLMN)：其为终端对应的用户归属的PLMN。(2) Home Public Land Mobile Network (Home Public Land Mobile Network, HPLMN): it is the PLMN to which the user corresponding to the terminal belongs.
如果全球用户识别卡(Universal Subscriber Identity Module，USIM)中存在EFEHPLMN且不为空，则HPLMN为该文件中的PLMN；如果USIM卡中不存在该文件，或者存在该文件，但该文件中列表为空，则HPLMN为从国际移动用户识别码(International MobileSubscriber Identification number，IMSI)中获取的MCC加上MNC。If EFEHPLMN exists in the Universal Subscriber Identity Module (USIM) and is not empty, then HPLMN is the PLMN in the file; if the file does not exist in the USIM card, or the file exists, but the file lists If it is empty, the HPLMN is the MCC obtained from the International Mobile Subscriber Identification number (IMSI) plus the MNC.
(3)用户控制公用陆地移动网络(User Public Land Mobile Network，UPLMN)：其为储存在用户身份识别卡(Subscriber Identity Module，SIM)上的一个与PLMN选择有关的参数，UPLMN为终端在用户进行手工选网时选择的PLMN。(3) User-controlled public land mobile network (User Public Land Mobile Network, UPLMN): It is a parameter related to PLMN selection stored on the Subscriber Identity Module (SIM). The PLMN selected during manual network selection.
(4)运营商控制公用陆地移动网络(User Public Land Mobile Network，OPLMN)：其为储存在SIM上的一个与PLMN选择有关的参数，主要为运营商对SIM进行烧卡时，将与该运营商签署了漫游协议的运营商PLMN作为OPLMN写入用户身份识别卡，以作用户漫游选网时的建议。(4) The operator controls the public land mobile network (User Public Land Mobile Network, OPLMN): it is a parameter related to PLMN selection stored on the SIM. The PLMN of the operator who has signed the roaming agreement is written into the user's identification card as the OPLMN, which is used as a suggestion for the user to roam and select a network.
在本申请实施例中，HPLMN的优先级大于UPLMN的优先级，UPLMN的优先级大于OPLMN的优先级。In the embodiment of the present application, the priority of the HPLMN is higher than that of the UPLMN, and the priority of the UPLMN is higher than that of the OPLMN.
2、UAC信息：网络设备通过系统消息(System Information Blocks 1，SIB1)广播的，配置了禁止的接入请求所对应的接入类型(access category，AC)和接入标识(accessidentity，AI)参数。通常，终端设备将接入请求映射为AC，将终端设备配置映射为接入标识AI，并结合UAC信息，确定终端设备的接入请求是否被禁止。2. UAC information: broadcast by network devices through System Information Blocks 1 (SIB1), configured with access category (AC) and access identity (AI) parameters corresponding to prohibited access requests . Usually, the terminal device maps the access request to the AC, maps the terminal device configuration to the access identity AI, and combines the UAC information to determine whether the access request of the terminal device is prohibited.
目前，在进行网络选择时，仅考虑PLMN类别的优先级，如一种常见的PLMN优先级顺序为RPLMN>HPLMN>UPLMN>OPLMN>高质量PLMN>低质量PLMN。在进行网络选择时，会选择优先级更高的网络进行驻留。当在某一个PLMN驻留成功后，在注册或业务发起时，非接入层(Non-Access Stratum，NAS)将注册请求或者业务请求映射成接入标识和接入类别传递给接入层(Access Stratum，AS)，AS根据接入标识及接入类别，结合SIB1中的UAC信息进行UAC检查。如果UAC检查允许，则该注册或业务可以发起；如果网络拥塞、UAC检查结果为禁止，则该注册或业务不能发起，需要等待UAC相关定时器T390，T302超时或者拥塞缓解才能重新尝试，再次进行UAC检查。其中T390的时长范围为(0.7+0.6*rand)*阻拦时间，rand为[0，1]之间随机数，阻拦时间(uac-BarringTime)来源于小区SIB1中的参数配置，通常在区间[4s，512s]内；T302的时长由基站侧在重配置释放(RRC_RELEASE)或重配置拒绝(RRC_REJECT)消息中携带的等待时间(waitTime)确定，时长一般为2s。Currently, only the priority of the PLMN category is considered during network selection, for example, a common PLMN priority order is RPLMN>HPLMN>UPLMN>OPLMN>high-quality PLMN>low-quality PLMN. When making network selection, the network with higher priority will be selected to reside on. After successfully camping in a certain PLMN, when registering or initiating a service, the Non-Access Stratum (Non-Access Stratum, NAS) maps the registration request or service request into an access identifier and an access category and transmits it to the access stratum ( Access Stratum, AS), the AS performs the UAC check according to the access identifier and the access category, combined with the UAC information in the SIB1. If the UAC check permits, the registration or service can be initiated; if the network is congested and the UAC check result is prohibited, the registration or service cannot be initiated, and it is necessary to wait for the UAC-related timer T390, T302 to expire or the congestion to be relieved before retrying and proceeding again UAC check. The duration range of T390 is (0.7+0.6*rand)*barring time, rand is a random number between [0, 1], and the barring time (uac-BarringTime) comes from the parameter configuration in the cell SIB1, usually in the interval [4s , 512s]; the duration of T302 is determined by the waiting time (waitTime) carried in the reconfiguration release (RRC_RELEASE) or reconfiguration rejection (RRC_REJECT) message on the base station side, and the duration is generally 2s.
基于目前协议框架，很有可能出现环境中存在多个合适网络的情况下，选网时选择了一个拥塞严重的小区，导致在进行注册或发起业务时UAC检查禁止，此时只能等待UAC相关定时器超时，超时后进行重试，但重试时依然有可能出现UAC检查继续禁止，重复多次后，用户感受下降。Based on the current protocol framework, it is very likely that when there are multiple suitable networks in the environment, a heavily congested cell is selected during network selection, resulting in the prohibition of UAC checks when registering or initiating services. At this time, you can only wait for UAC related information. The timer expires and a retry is performed after the timeout. However, the UAC check may continue to be prohibited during the retry. After repeated multiple times, the user experience decreases.
示例性地，如图1所示，终端设备在初始态进行搜网使用了TSearch时长的时间。终端设备进行驻留注册使用了TRegistration时长的时间。终端设备第一次发起业务，UAC检查禁止，终端设备等待UAC定时器超时使用了T时长的时间，终端设备第二次发起业务，UAC检查又禁止，终端设备又等待UAC定时器超时使用了T时长的时间，如此，发起业务、UAC检查禁止、等待UAC定时器重复多次后，终端设备花费Twaste时长才正常发起业务。在Twaste时长终端设备一直无法入网，无法进行注册或发起业务，最终导致终端设备入网效率低，用户感受下降。Exemplarily, as shown in FIG. 1 , the terminal device uses TSearch to search the Internet in an initial state. The terminal device uses TRegistration for resident registration. When the terminal device initiates a service for the first time, the UAC check is prohibited, and the terminal device waits for the UAC timer to expire for a period of T. When the terminal device initiates a service for the second time, the UAC check is prohibited again. In this way, after initiating services, UAC checks and prohibitions, and waiting for the UAC timer to repeat multiple times, the terminal device takes Twaste time to initiate services normally. For a long time in Twaste , terminal devices have been unable to access the network, cannot register or initiate services, which eventually leads to low network access efficiency of terminal devices and a decline in user experience.
为了解决上述问题，本申请实施例中，可以通过获取第一信息；根据第一信息，从该至少一个第一小区中确定待驻留小区。其中，第一信息包括：第一PLMN，第一PLMN下的至少一个第一小区的UAC信息，第一PLMN对应的至少一个预判接入标识，以及至少一个预判接入类别。本方案中，终端设备结合UAC信息，至少一个预判接入标识，以及至少一个预判接入类别进行搜网，可以确定一个拥塞情况较好的小区进行驻留，从而在进行注册或发起业务时UAC检查禁止的可能性会降低，如此，可以提高终端设备的入网效率。In order to solve the above problem, in the embodiment of the present application, the cell to be camped on may be determined from the at least one first cell according to the first information by acquiring the first information. Wherein, the first information includes: the first PLMN, UAC information of at least one first cell under the first PLMN, at least one pre-judged access identifier corresponding to the first PLMN, and at least one pre-judged access category. In this solution, the terminal device combines UAC information, at least one pre-judged access identifier, and at least one pre-judged access type to search the network, and can determine a cell with better congestion to camp on, so as to register or initiate a service The possibility of UAC check and prohibition will be reduced, so that the network access efficiency of the terminal device can be improved.

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的搜网方法进行详细地说明。The method for searching the Internet provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.
如图3所示，本申请实施例提供一种搜网方法，下面以执行主体为终端设备为例，对本申请实施例提供的搜网方法进行示例性的说明。该方法可以包括下述的步骤301至步骤302。As shown in FIG. 3 , the embodiment of the present application provides a network searching method. The following uses a terminal device as an example to illustrate the network searching method provided in the embodiment of the present application. The method may include
301、终端设备获取第一信息。301. The terminal device acquires first information.
其中，第一信息包括：第一PLMN，第一PLMN下的至少一个第一小区的UAC信息，第一PLMN对应的至少一个预判接入标识，以及至少一个预判接入类别。Wherein, the first information includes: the first PLMN, UAC information of at least one first cell under the first PLMN, at least one pre-judged access identifier corresponding to the first PLMN, and at least one pre-judged access category.
可以理解，该至少一个预判接入标识可以包括一个或者多个接入标识，该至少一个预判接入类别可以包括一个或者多个判接入类别。It can be understood that the at least one pre-determined access identifier may include one or more access identifiers, and the at least one pre-determined access category may include one or more pre-determined access categories.
可选地，为了保证搜网效率，预判接入类别的数量可以进行控制，比如每次搜网要求不要超过N个(例如，N＝3)。Optionally, in order to ensure network search efficiency, the number of pre-judged access categories can be controlled, for example, no more than N (for example, N=3) is required for each network search.
其中，该至少一个预判接入标识是根据终端设备的USIM卡中的相关信息以及第一PLMN共同确定的，该相关信息用于指示不同的PLMN对应的接入标识。因此，该至少一个预判接入标识是由中USIM卡和选择的PLMN共同决定的。Wherein, the at least one predicted access identifier is jointly determined according to related information in the USIM card of the terminal device and the first PLMN, and the related information is used to indicate the corresponding access identifiers of different PLMNs. Therefore, the at least one pre-determined access identifier is jointly determined by the USIM card and the selected PLMN.
302、终端设备根据第一信息，从该至少一个第一小区中确定待驻留小区。302. The terminal device determines a cell to camp on from the at least one first cell according to the first information.
本申请实施例中，待驻留小区是满足驻留条件的小区。满足驻留条件小区需满足以下条件：驻留的S准则，不是保留的小区、不是禁止的小区，也不是禁止PLMN的小区。In this embodiment of the present application, the cell to be camped on is a cell that satisfies the camping condition.

For a specific determination method, reference may be made to related technologies, which will not be repeated here.
可选地，终端设备根据当前的业务需要或历史业务需要等，确定该至少一个预判接入类别。Optionally, the terminal device determines the at least one pre-judged access category according to current service requirements or historical service requirements.
示例性地，该至少一个预判接入类别是根据以下至少一项确定的：已发起但被UAC禁止的业务请求对应的阻塞业务接入类别；预约业务对应的预约业务接入类别；预设时长内使用频率大于或等于频率阈值的统计业务接入类别；本次注册请求对应的注册接入类别。Exemplarily, the at least one predicted access category is determined according to at least one of the following: the blocked service access category corresponding to the service request that has been initiated but prohibited by the UAC; the reserved service access category corresponding to the reserved service; the preset The statistical service access category whose use frequency is greater than or equal to the frequency threshold within the duration; the registration access category corresponding to this registration request.
其中，该预约业务的时间距当前时刻的时长小于或等于时长阈值。时长阈值可以根据实际使用情况确定，本申请实施例不做限定。Wherein, the duration of the reservation service from the current moment is less than or equal to the duration threshold. The duration threshold can be determined according to actual usage conditions, and is not limited in this embodiment of the present application.
可以理解，该至少一个预判接入类别包括阻塞业务接入类别、预约业务接入类别、统计业务接入类别和注册接入类别中的一项或多项。预判接入类别还可以包括其他类型的接入类别，本申请实施例不做限定。It can be understood that the at least one predictive access category includes one or more of a blocking service access category, a reservation service access category, a statistical service access category, and a registration access category. The predicted access category may also include other types of access categories, which is not limited in this embodiment of the present application.
其中，针对阻塞业务接入类别：如果当前用户已经发起了某业务，但该业务被UAC禁止，那么该业务所对应的接入类别即为当前需要关注的接入类别，将其增加到预判接入类别中。Among them, for the blocked service access category: if the current user has initiated a certain service, but the service is prohibited by UAC, then the access category corresponding to the service is the current access category that needs attention, and it is added to the pre-judgment access category.
可以理解，刚开机时终端设备不允许在未注册的情况下发起业务，但在移动性更新或周期性更新的过程中，由于在前一个状态时已经注册(注册状态)过，则在改派的过程中发起的业务，如果被UAC禁止，则该业务的接入类别确定为一个预判接入类别。It can be understood that the terminal device is not allowed to initiate services without registration when it is just turned on, but during the process of mobility update or periodic update, since it has already registered (registered state) in the previous state, it will be reassigned If the service initiated during the process is prohibited by the UAC, the access category of the service is determined as a pre-judged access category.
其中，针对预约业务接入类别：如果用户当前尚未发起业务，但用户预约了某业务，且该预约业务即将发起，如通过记事本，备忘录等预定某个时间点将要发起某业务，且预定的时间点已接近(预约业务的时间距当前时刻的时长小于或等于时长阈值)，则该业务所对应的接入类别也为当前需要关注的接入类别，将其增加到预判接入类别中。Among them, for the reservation service access category: if the user has not yet initiated the service, but the user has reserved a certain service, and the reservation service is about to start, for example, through a notepad, a memo, etc. to schedule a certain time point to initiate a certain service, and the scheduled The time point is approaching (the time between the reserved service and the current time is less than or equal to the duration threshold), then the access category corresponding to the service is also the access category that needs attention at present, and it is added to the predicted access category .
例如，预约业务为观看比赛直播，该预约业务对速率要求比较高，在当前时刻距预约时间的时长小于或等于时长阈值时，如果当前驻留小区的业务速率较差，预约业务可能会被UAC禁止，终端设备可以自动切换到其他速率较好的小区，也可以在切换之前提示用户当前驻留小区速率较差，需要切换到速率较好的小区。For example, the reservation service is to watch a live game. The reservation service has relatively high speed requirements. When the time between the current time and the reservation time is less than or equal to the time threshold, if the service speed of the current residential cell is poor, the reservation service may be blocked by the UAC. Prohibited, the terminal device can automatically switch to other cells with better speed, and can also prompt the user to switch to a cell with better speed before the handover.
其中，针对统计业务接入类别：统计预设时长内各接入请求的接入类别，根据统计的信息，如果用户经常发起某种接入类别的业务，则该接入类别同样需要关注，将其加入到预判接入类别中。Among them, for the statistical service access category: the access category of each access request within the preset time period is counted. According to the statistical information, if the user often initiates a service of a certain access category, this access category also needs to be paid attention to. It is added to the prejudgment access category.
其中，注册接入类别：注册请求也需要关注，尤其驻留到新PLMN时，将注册请求对应的接入类别也增加到预判接入类别中。Among them, the registration access category: the registration request also needs attention, especially when camping on a new PLMN, the access category corresponding to the registration request is also added to the pre-judgment access category.
示例性地，NAS根据当前的业务需要或历史业务需要等，确定该至少一个预判接入类别。Exemplarily, the NAS determines the at least one pre-judged access category according to current service requirements or historical service requirements.
本申请实施例中，终端设备可以根据当前的业务需要或历史业务需要等，确定该至少一个预判接入类别，从而终端设备可以更好地根据该至少一个预判接入类别，确定待驻留小区。In this embodiment of the present application, the terminal device can determine the at least one predicted access category according to the current business needs or historical business needs, so that the terminal device can better determine the waiting time based on the at least one predicted access category. Stay in the neighborhood.
可选地，可以根据终端设备的不同需求为该至少一个预判接入类别设置优先级。Optionally, priority may be set for the at least one pre-judged access category according to different requirements of terminal devices.
示例性地，该注册接入类别的优先级高于该阻塞业务接入类别的优先级；该阻塞业务接入类别的优先级高于该预约业务接入类别的优先级；该预约业务接入类别的优先级高于该统计业务接入类别。Exemplarily, the priority of the registered access category is higher than the priority of the blocked service access category; the priority of the blocked service access category is higher than the priority of the reserved service access category; the reserved service access The priority of the category is higher than that of the statistical service access category.
示例性地，该至少一个预判接入标识可以为列表的形式，该至少一个预判接入类别也可以为列表的形式。且接入类别列表中预判接入类别按照优先级顺序由高到低排列，其优先级的定义由当前的场景具体决定，如当前需要进行注册后才能进行业务，则注册请求对应的注册接入类别的优先级最高；如当前不需要进行注册，仅需要执行用户业务，则业务对应的预判接入类别的优先级更高，例如，阻塞业务接入类别的优先级高于该预约业务接入类别的优先级，该预约业务接入类别的优先级高于该统计业务接入类别。Exemplarily, the at least one pre-judged access identifier may be in the form of a list, and the at least one pre-judged access category may also be in the form of a list. In addition, the pre-judged access categories in the access category list are arranged in order of priority from high to low, and the definition of the priority is determined by the current scenario. The priority of the access category is the highest; if there is no need to register and only need to perform user services, the priority of the predicted access category corresponding to the service is higher. For example, the priority of the blocked service access category is higher than that of the reserved service. The priority of the access category, the priority of the reservation service access category is higher than the statistics service access category.
本申请实施例中，根据实际接入场景的需要，确定至少一个预判接入类别中每个预判接入类别的优先级，进而可以更好地根据该至少一个预判接入类别，确定待驻留小区。In this embodiment of the application, according to the needs of the actual access scenario, the priority of each of the at least one pre-judged access category is determined, and then the priority of each predicted access category can be better determined based on the at least one predicted access category. Stay in the area.
步骤301c、终端设备获取第一PLMN下的该至少一个第一小区的UAC信息。Step 301c, the terminal device acquires UAC information of the at least one first cell under the first PLMN.
示例性地，AS从每个第一小区的SIB1消息中获取该小区的UAC信息，以得到该至少一个第一小区的UAC信息。Exemplarily, the AS obtains the UAC information of each first cell from the SIB1 message of the cell, so as to obtain the UAC information of the at least one first cell.
示例性地，如图4所示，以通过NAS和AS获取第一信息为例，上述步骤301a至步骤301c具体可以通过下述步骤401至步骤405实现。Exemplarily, as shown in FIG. 4 , taking the acquisition of the first information through the NAS and the AS as an example, the foregoing steps 301 a to 301 c may be specifically implemented through the following steps 401 to 405 .
401、NAS确定第一PLMN。401. The NAS determines the first PLMN.
402、NAS确定至少一个预判接入标识和至少一个预判接入类别。402. The NAS determines at least one pre-judged access identifier and at least one pre-judged access category.
403、NAS向AS发送第一搜网请求消息。403. The NAS sends a first network search request message to the AS.
第一搜网请求消息(PlmnSearchReq)中携带第一PLMN，至少一个预判接入标识以及至少一个预判接入类别。第一搜网请求(PlmnSearchReq)消息用于指示AS驻留在第一PLMN上，同时尽量选择满足该至少一个预判接入标识和该至少一个预判接入类别的小区进行驻留。The first network search request message (PlmnSearchReq) carries the first PLMN, at least one pre-judged access identifier and at least one pre-judged access category. The first network search request (PlmnSearchReq) message is used to instruct the AS to camp on the first PLMN, and at the same time try to select a cell that satisfies the at least one pre-judged access identifier and the at least one pre-judged access category to camp on.
需要说明的是，当第一PLMN，至少一个预判接入标识以及至少一个预判接入类别中的任一个发生变化时，NAS可以将更新后的内容发送给AS(例如，预判接入类别发生变化，则NAS在更新该至少一个预判接入类别之后，NAS将更新后的至少一个预判接入类别发送给AS)，以便AS收到之后，根据更新后的内容进行小区重选，得到更满足接入需求的小区进行驻留。如此可以保证AS的自主性，以及NAS和AS的同步性，以避免因NAS和AS不同步AS选择的小区不是满足接入需求的小区。It should be noted that when any one of the first PLMN, at least one pre-judged access identifier, and at least one pre-judged access category changes, the NAS can send the updated content to the AS (for example, the pre-judged access If the category changes, after the NAS updates the at least one predicted access category, the NAS will send the updated at least one predicted access category to the AS, so that after the AS receives it, it can perform cell reselection according to the updated content , to obtain a cell that better meets the access requirements for camping. In this way, the autonomy of the AS and the synchronization of the NAS and the AS can be guaranteed, so as to avoid that the cell selected by the AS is not a cell that meets the access requirements due to the out-of-synchronization of the NAS and the AS.
404、AS从NAS接收到第一搜网请求消息后，从网络设备接收每个第一小区的SIB1消息。404. After receiving the first network search request message from the NAS, the AS receives the SIB1 message of each first cell from the network device.
405、AS从每个第一小区的SIB1消息中获取该小区的UAC信息。405. The AS obtains the UAC information of each first cell from the SIB1 message of the cell.
AS从NAS接收到第一搜网请求消息后，执行第一PLMN下的小区搜索驻留流程。具体地，在原有流程的基础上，AS从每个第一小区的SIB1消息中获取该小区的UAC信息，以得到该至少一个第一小区的UAC信息，然后基于该至少一个第一小区的UAC信息，至少一个预判接入标识和至少一个预判接入类别确定待驻留小区。After receiving the first network search request message from the NAS, the AS executes a cell search and camping process under the first PLMN. Specifically, on the basis of the original procedure, the AS obtains the UAC information of each first cell from the SIB1 message of the cell to obtain the UAC information of the at least one first cell, and then based on the UAC information of the at least one first cell Information, at least one pre-judged access identifier and at least one pre-judged access category determine the cell to camp on.
本申请实施例中，NAS会结合PLMN优先级，根据当前场景预判当前接入需求(至少一个预判接入标识和至少一个预判接入类别)，并将至少一个预判接入标识和至少一个预判接入类别传递给AS，使得AS在特定PLMN(本申请实施例中，特定PLMN即NAS选择的PLMN)下选择最优小区，保证用户入网及业务。本方案大大降低UAC检查禁止的概率，最好情况下，可以完全能避免UAC检查禁止场景。In this embodiment of the application, the NAS will predict the current access requirements (at least one predicted access identifier and at least one predicted access category) according to the current scenario in combination with the PLMN priority, and combine at least one predicted access identifier and At least one pre-judged access category is passed to the AS, so that the AS selects the optimal cell under a specific PLMN (in the embodiment of this application, the specific PLMN is the PLMN selected by the NAS) to ensure user network access and services. This solution greatly reduces the probability of UAC check ban, and in the best case, can completely avoid the UAC check ban scenario.

In this embodiment of the present application, in the process of determining the first PLMN from at least two third PLMNs, a plurality of third PLMNs whose priority is greater than or equal to the preset priority is first determined, and then the plurality of third PLMNs Among them, the PLMN of the cell with better congestion based on the access demand is determined as the first PLMN (this process can refer to the relevant description in the above steps 301e1 and 301e2, which will not be repeated here).
本申请实施例中，优先级为选择PLMN的优先选择标准，在同等优先级的前提下，再考虑终端设备的接入需求(即至少一个预判接入标识和至少一个预判接入类别)，确定最满足接入需求的PLMN。如此，可以满足现有协议对优先级的要求，在没有用户同意的情况不会因降低优先级产生相应资费，而且在同等优先级的前提下，可以确定满足接入需求的PLMN。In the embodiment of this application, the priority is the priority selection standard for selecting the PLMN. On the premise of the same priority, the access requirements of the terminal equipment (that is, at least one pre-judged access identifier and at least one pre-judged access category) are considered. , to determine the PLMN that best meets the access requirements. In this way, the priority requirements of the existing protocol can be met, and no corresponding charges will be generated for lowering the priority without the consent of the user, and under the premise of the same priority, the PLMN that meets the access requirements can be determined.
可选地，NAS在结合UAC信息选择PLMN时，可以仅考虑同优先级类型的PLMN之间的优化选择，例如，环境中包括多个UPLMN时，每个UPLMN下小区的UAC信息与接入需求的匹配程度不同，自行选择与接入需求匹配程度最好的UPLMN，避免与用户交互，降低复杂度。Optionally, when the NAS selects a PLMN in combination with the UAC information, it may only consider the optimal selection between PLMNs of the same priority type. For example, when the environment includes multiple UPLMNs, the UAC information and access requirements of the cells under each UPLMN The degree of matching between different users is different, and the UPLMN that best matches the access requirements is selected by oneself to avoid interaction with users and reduce complexity.
示例性地，如图5所示，以通过NAS和AS获取第三信息，并根据第三信息确定第一PLMN为例，上述步骤301d具体可以通过下述步骤501至步骤510实现。Exemplarily, as shown in FIG. 5 , taking the third information obtained through the NAS and the AS as an example, and the first PLMN determined according to the third information, the above step 301d may be specifically implemented through the following steps 501 to 510 .
501、NAS向AS发送第二搜网请求消息。501. The NAS sends a second network search request message to the AS.
第二搜网请求消息(PlmnSearchListReq)用于指示获取所有PLMN，以及获取每个PLMN下的小区的UAC信息。The second network search request message (PlmnSearchListReq) is used to instruct to obtain all PLMNs, and to obtain UAC information of cells under each PLMN.
相应地，AS从NAS接收第二搜网请求消息。Correspondingly, the AS receives the second network search request message from the NAS.
502、AS根据第二搜网请求消息，获取至少两个第三PLMN，每个第三PLMN下的至少一个第三小区的UAC信息。502. The AS obtains, according to the second network search request message, at least two third PLMNs, and UAC information of at least one third cell under each third PLMN.
503、AS向NAS发送第一搜网响应消息。503. The AS sends a first network search response message to the NAS.
第一搜网响应消息(PlmnSearchCnf)用于指示所有PLMN及对应的UAC信息的搜索结果。第一搜网响应消息种携带至少两个第三PLMN，每个第三PLMN下的至少一个第三小区的UAC信息。The first network search response message (PlmnSearchCnf) is used to indicate search results of all PLMNs and corresponding UAC information. The first network search response message carries at least two third PLMNs, and UAC information of at least one third cell under each third PLMN.
相应地，NAS从AS接收第一搜网响应消息。Correspondingly, the NAS receives the first network search response message from the AS.
504、NAS从第一搜网响应消息中获取至少两个第三PLMN，每个第三PLMN下的至少一个第三小区的UAC信息。504. The NAS acquires at least two third PLMNs, and UAC information of at least one third cell under each third PLMN from the first network search response message.
505、NAS获取每个第三PLMN对应的至少一个目标预判接入标识。505. The NAS acquires at least one target pre-judgment access identifier corresponding to each third PLMN.

507、NAS对该至少两个第三PLMN进行优先级排序。507. The NAS performs priority sorting on the at least two third PLMNs.
示例性地，NAS获取该至少两个第三PLMN后，将该至少两个第三PLMN按照现有方案进行优先级排序，例如：Exemplarily, after the NAS acquires the at least two third PLMNs, the at least two third PLMNs are prioritized according to an existing scheme, for example:
1)更高优先级PLMN(Higher Priority PLMN，HPPLMN)定时器超时的场景下：HPLMN优先级最高，UPLMN次之，OPLMN更次之，依次类推。1) In the scenario where the Higher Priority PLMN (Higher Priority PLMN, HPPLMN) timer expires: HPLMN has the highest priority, followed by UPLMN, followed by OPLMN, and so on.
2)其他场景(开机或丢覆盖场景)下，RPLMN优先级最高，HPLMN优先级次之，UPLMN再次之，OPLMN更次之，依次类推。2) In other scenarios (power-on or coverage loss scenarios), RPLMN has the highest priority, followed by HPLMN, followed by UPLMN, followed by OPLMN, and so on.
508、NAS按照优先级从高到低的顺序，依次根据每个第三PLMN下的至少一个第三小区的UAC信息，与对应的至少一个目标预判接入标识和至少一个预判接入类别进行检查比对，确定每个第三PLMN下是否存在满足接入需求的小区。508. The NAS, according to the order of priority from high to low, sequentially according to the UAC information of at least one third cell under each third PLMN, and the corresponding at least one target pre-judgment access identifier and at least one pre-judgment access category A check and comparison is performed to determine whether there is a cell meeting the access requirement under each third PLMN.
具体地，小区的UAC信息，与对应的至少一个目标预判接入标识和至少一个预判接入类别进行检查比对的方法可以参考下述步骤302中的相关描述，此处不予赘述。Specifically, the method of checking and comparing the UAC information of the cell with the corresponding at least one target predicted access identifier and at least one predicted access category can refer to the relevant description in the following
509、在优先级最高的第三PLMN存在完全满足接入需求的小区的情况下，NAS将该优先级最高的第三PLMN确定为第一PLMN。509. In a case where there is a cell fully meeting the access requirement in the third PLMN with the highest priority, the NAS determines the third PLMN with the highest priority as the first PLMN.
可以理解，该优先级最高的第三PLMN(以下记为PLMN 1)下存在小区1(对应上述步骤301e1中的第三目标小区)，小区1的UAC信息完全允许基于PLMN 1对应的至少一个目标预判接入标识和每个预判接入类别的接入请求。It can be understood that there is cell 1 (corresponding to the third target cell in step 301e1) under the third PLMN with the highest priority (hereinafter referred to as PLMN 1), and the UAC information of cell 1 fully allows at least one target cell based on PLMN 1 to The pre-judged access identifier and the access request of each pre-judged access category.
510、在多个目标第一PLMN存在不同程度满足接入需求的小区的情况下，NAS将与接入需求匹配程度最高的小区所属的目标第一PLMN(以下记为PLMN 2)确定为第一PLMN。510. In the case that multiple target first PLMNs have cells that meet the access requirements to varying degrees, the NAS determines the target first PLMN (hereinafter referred to as PLMN 2) to which the cell that most closely matches the access requirements belongs to be the first PLMN.
该多个目标第一PLMN为：该至少两个第三PLMN中，优先级相同，且优先级大于或等于预设优先级的PLMN。The multiple target first PLMNs are: among the at least two third PLMNs, PLMNs with the same priority and greater than or equal to a preset priority.
可以理解，PLMN 2下存在小区2(对应上述步骤301e2中的第四目标小区)，小区2为：该多个目标第一PLMN下所有小区中，UAC信息允许基于对应的至少一个目标预判接入标识和每个预判接入类别的接入请求的概率最高的小区。It can be understood that there is a cell 2 under the PLMN 2 (corresponding to the fourth target cell in the above step 301e2), and the cell 2 is: among all the cells under the multiple target first PLMNs, the UAC information allows pre-judgment based on at least one corresponding target. The access ID and the cell with the highest probability of access request for each pre-judged access category.
可选地，上述步骤510包括下述步骤510a。Optionally, the above step 510 includes the following step 510a.
510a、在优先级大于或等于预设优先级的多个目标第一PLMN中不存在完全满足接入需求的小区，但优先级小于预设优先级的目标第二PLMN(相当于下述步骤306b中的第四PLMN)存在完全满足接入需求的小区的情况下，NAS将与接入需求匹配程度最高的小区所属的目标第一PLMN(以下记为PLMN 2)确定为第一PLMN。510a. There is no cell that fully meets the access requirements among the multiple target first PLMNs whose priority is greater than or equal to the preset priority, but the target second PLMN whose priority is lower than the preset priority (equivalent to the following step 306b In the fourth PLMN) there is a cell that fully meets the access requirements, the NAS determines the target first PLMN (hereinafter referred to as PLMN 2) to which the cell that most matches the access requirements belongs to as the first PLMN.
其中，目标第二PLMN为：该至少两个第三PLMN中，优先级小于预设优先级的PLMN。Wherein, the target second PLMN is: among the at least two third PLMNs, a PLMN whose priority is lower than a preset priority.
可以理解，在无用户允许的情况下，优先选择优先级大于或等于预设优先级的第三PLMN作为第一PLMN，然后在第一PLMN下选择与接入需求匹配程度最高的小区(以下记为小区3)进行驻留。在小区3进行注册或发起业务时UAC检查禁止的情况下，NAS可以告知终端设备，终端设备可以通过显示提示信息，以提示用户优先级小于预设优先级的目标第二PLMN下存在完全满足接入需求的小区，是否切换到该目标第二PLMN下重新搜网。然后根据用户的选择，终端设备确定是继续等待小区3拥塞缓解(例如，等待UAC定时器超时)之后重新尝试接入请求，还是切换到目标第二PLMN下重新搜网。It can be understood that in the case of no user permission, the third PLMN whose priority is greater than or equal to the preset priority is preferentially selected as the first PLMN, and then the cell with the highest degree of matching with the access requirement is selected under the first PLMN (recorded below Camp for cell 3). When the UAC check is prohibited when cell 3 registers or initiates a service, the NAS can notify the terminal device, and the terminal device can display a prompt message to prompt the user that there is a target second PLMN with a priority lower than the preset priority that fully meets the access requirements. whether to switch to the target second PLMN to search the network again. Then according to the user's choice, the terminal device determines whether to continue to wait for the congestion relief of cell 3 (for example, wait for the UAC timer to expire) and then retry the access request, or switch to the target second PLMN to search the network again.
本申请实施例中，各小区的UAC信息由AS上报至NAS，NAS在选择网络时，不仅可以考虑PLMN优先级，还可以综合考虑各个PLMN下的小区与接入需求的匹配程度(小区UAC信息是否允许基于该至少一个预判接入标识和每个预判接入类别的接入请求)。进而可以选择拥塞情况最好的小区进行驻留，以保证用户入网及业务。本申请实施例中，NAS和AS对于小区与接入需求的匹配程度的判断方法相同，没有增加复杂性。In this embodiment of the application, the UAC information of each cell is reported by the AS to the NAS. When the NAS selects a network, it can not only consider the priority of the PLMN, but also comprehensively consider the degree of matching between the cells under each PLMN and the access requirements (cell UAC information Whether to allow an access request based on the at least one pre-judged access identifier and each pre-judged access category). Furthermore, the cell with the best congestion situation can be selected for camping, so as to ensure the user's network access and services. In the embodiment of the present application, the NAS and the AS judge the matching degree of the cell and the access requirement in the same way, without increasing the complexity.
可选地，上述步骤302具体可以通过下述步骤302a或步骤302b或步骤302c实现。Optionally, the
302a、终端设备在该至少一个第一小区中包括第一目标小区的情况下，将第一目标小区确定为该待驻留小区。302a. When the at least one first cell includes the first target cell, the terminal device determines the first target cell as the cell to camp on.
其中，第一目标小区为该至少一个第一小区中，UAC信息完全允许基于该至少一个预判接入标识和每个该预判接入类别的接入请求的小区。Wherein, the first target cell is a cell in the at least one first cell for which the UAC information fully allows an access request based on the at least one pre-judged access identifier and each of the pre-judged access categories.
本申请实施例中，第一目标小区为完全满足接入需求的小区，将第一目标小区确定为待驻留小区，在第一目标小区进行驻留后，在进行注册或发起业务时UAC检查不会被禁止，如此，可以提高终端设备的入网效率。In the embodiment of this application, the first target cell is a cell that fully meets the access requirements, and the first target cell is determined as the cell to be camped on. After camping on the first target cell, UAC checks when registering or initiating services It will not be banned, so the network access efficiency of the terminal equipment can be improved.
可选地，第一目标小区的UAC信息包括以下任一项：UAC信息为空；UAC信息不包括针对第一PLMN的限制信息；UAC信息不包括该至少一个预判接入标识和该至少一个预判接入类别。Optionally, the UAC information of the first target cell includes any of the following: the UAC information is empty; the UAC information does not include restriction information for the first PLMN; the UAC information does not include the at least one predicted access identifier and the at least one Predict the access category.
第一种情况，UAC信息为空，即为小区服务的网络设备未设置UAC信息。例如，网络设备广播的SIB1中的UAC限制信息(uac-BarringInfo)内容为空。In the first case, the UAC information is empty, that is, no UAC information is set on the network device serving the cell. For example, the UAC barring information (uac-BarringInfo) in the SIB1 broadcast by the network device is empty.
第二种情况，网络设备设置了UAC信息，UAC信息不包括针对第一PLMN的限制信息。例如，网络设备广播的SIB1中仅存在UAC公共限制PLMN列表(uac-BarringPerPlmn-List)，不存在UAC公共限制信息(uac-BarrgingForCommon)项，且uac-BarringPerPlmn-List中不存在本次选择的第一PLMN(prefer PLMN)。In the second case, the network device sets UAC information, and the UAC information does not include restriction information for the first PLMN. For example, there is only the UAC public barring PLMN list (uac-BarringPerPlmn-List) in the SIB1 broadcast by the network device, there is no UAC public barring information (uac-BarringForCommon) item, and the uac-BarringPerPlmn-List does not exist in the uac-BarringPerPlmn-List. - PLMN (prefer PLMN).
其中，uac-BarringPerPlmn-List只包括对该列表中的PLMN的限制信息，uac-BarrgingForCommon中包括对所有PLMN的限制信息。在SIB1中仅包括uac-BarringPerPlmn-List，不包括uac-BarrgingForCommon的情况下，只对uac-BarringPerPlmn-List中的PLMN进行相应限制；在SIB1中仅包括uac-BarrgingForCommon，不包括uac-BarringPerPlmn-List的情况下，根据uac-BarrgingForCommon，对所有PLMN进行相应限制；在SIB1中既包括uac-BarringPerPlmn-List，又包括uac-BarrgingForCommon的情况下，根据uac-BarringPerPlmn-List对在该列表中的PLMN进行相应限制，根据uac-BarrgingForCommon对除uac-BarringPerPlmn-List之外的PLMN进行相应限制。因此，SIB1中仅存在uac-BarringPerPlmn-List，不存在uac-BarrgingForCommon项，且uac-BarringPerPlmn-List中不存在本次选择的第一PLMN的情况下，该UAC信息不包括针对第一PLMN的限制信息。Among them, uac-BarringPerPlmn-List only includes the restriction information of the PLMNs in the list, and uac-BarringForCommon includes the restriction information of all PLMNs. When only uac-BarringPerPlmn-List is included in SIB1, and uac-BarringPerPlmn-List is not included, only the PLMN in uac-BarringPerPlmn-List is restricted accordingly; only uac-BarringPerPlmn-List is included in SIB1, uac-BarringPerPlmn-List is not included In the case of SIB1, all PLMNs are restricted according to uac-BarringForCommon; when SIB1 includes both uac-BarringPerPlmn-List and uac-BarringForCommon, the PLMNs in the list are restricted according to uac-BarringPerPlmn-List Corresponding restrictions, according to uac-BarringForCommon, corresponding restrictions are imposed on PLMNs other than uac-BarringPerPlmn-List. Therefore, if there is only uac-BarringPerPlmn-List in SIB1, there is no uac-BarringForCommon item, and the first PLMN selected this time does not exist in uac-BarringPerPlmn-List, the UAC information does not include restrictions on the first PLMN information.
第三种情况，UAC信息不包括该至少一个预判接入标识和该至少一个预判接入类别。网络设备广播的SIB1包括以下4种情况：In the third case, the UAC information does not include the at least one pre-judged access identifier and the at least one pre-judged access category. SIB1 broadcast by network devices includes the following four situations:
情况1，SIB1中仅存在uac-BarringPerPlmn-List，不存在uac-BarrgingForCommon项，且uac-BarringPerPlmn-List中存在本次选择的第一PLMN，但对第一PLMN的限制信息中不包括该至少一个预判接入标识和该至少一个预判接入类别；Case 1, only uac-BarringPerPlmn-List exists in SIB1, there is no uac-BarringForCommon item, and the first PLMN selected this time exists in uac-BarringPerPlmn-List, but the restriction information for the first PLMN does not include at least one A pre-judged access identifier and the at least one pre-judged access category;
情况2，SIB1中仅存在uac-BarrgingForCommon项，不存在uac-BarringPerPlmn-List，且uac-BarrgingForCommon项对第一PLMN的限制信息中不包括该至少一个预判接入标识和该至少一个预判接入类别；In case 2, there is only uac-BarringForCommon item in SIB1, there is no uac-BarringPerPlmn-List, and the restriction information of uac-BarringForCommon item on the first PLMN does not include the at least one pre-judgment access identifier and the at least one pre-judgment access ID into the category;
情况3，SIB1中存在uac-BarringPerPlmn-List和uac-BarrgingForCommon项，且uac-BarringPerPlmn-List中存在本次选择的第一PLMN，但对第一PLMN的限制信息中不包括该至少一个预判接入标识和该至少一个预判接入类别；Situation 3: There are items uac-BarringPerPlmn-List and uac-BarringForCommon in SIB1, and the first PLMN selected this time exists in uac-BarringPerPlmn-List, but the restriction information for the first PLMN does not include the at least one pre-judgment connection The access identifier and the at least one pre-judged access category;
情况4，SIB1中存在uac-BarringPerPlmn-List和uac-BarrgingForCommon项，且uac-BarringPerPlmn-List中不存在本次选择的第一PLMN，但uac-BarrgingForCommon项对第一PLMN的限制信息中不包括该至少一个预判接入标识和该至少一个预判接入类别。Situation 4: There are items uac-BarringPerPlmn-List and uac-BarringForCommon in SIB1, and the first PLMN selected this time does not exist in uac-BarringPerPlmn-List, but the restriction information of item uac-BarringForCommon on the first PLMN does not include this At least one pre-judged access identifier and the at least one pre-judged access category.
本申请实施例中，提供了第一目标小区完全满足接入需求的多种UAC信息的可能性，从而终端设备可以将满足上述任一种UAC信息条件的小区，确定为第一目标小区。In the embodiment of the present application, the possibility is provided that the first target cell fully meets various UAC information required for access, so that the terminal device can determine a cell that meets any of the above UAC information conditions as the first target cell.
可选地，在该至少一个第一小区中，同时存在满足上述第一种情况或第二种情况的小区，以及满足上述第三种情况的小区的情况下，终端设备优先选择满足上述第一种情况或第二种情况的小区，作为第一目标小区，因为满足上述第一种情况或第二种情况的小区度UAC信息，不包括针对第一PLMN的限制信息，则该小区在第一PLMN下不存在拥塞，速率较高，选择该小区进行驻留，在进行注册或发起业务(即使是除至少一个预判接入标识和至少一个预判接入类别之外的接入请求)时UAC检查不会被禁止，如此，可以提高终端设备的入网效率。Optionally, in the case where a cell satisfying the above first condition or the second condition and a cell satisfying the above third condition exist at the same time in the at least one first cell, the terminal device preferentially selects the cell satisfying the above first condition. The cell in the first case or the second case is used as the first target cell, because the cell degree UAC information that satisfies the above first case or the second case does not include restriction information for the first PLMN, then the cell is in the first target cell. There is no congestion under the PLMN, the rate is high, and the cell is selected for camping, when registering or initiating services (even if it is an access request other than at least one pre-judged access identifier and at least one pre-judged access category) The UAC check will not be prohibited, so that the network access efficiency of the terminal device can be improved.
可选地，在确定该至少一个第一小区中，存在满足上述第一种情况或第二种情况的小区之后，可以直接将该小区确定为第一目标小区，不在对其他小区是否满足接入需求进行判断(例如，可以设置其他小区的uac-BarringFactor均为0，即假定其他小区的UAC信息禁止基于至少一个预判接入标识和至少一个预判接入类别的接入请求，则无需再考虑其他小区)，如此可以减少检查比对过程，提高待驻留小区的确定效率。Optionally, after it is determined that among the at least one first cell, there is a cell that satisfies the above-mentioned first condition or the second condition, the cell may be directly determined as the first target cell, regardless of whether other cells satisfy the access requirements. needs to judge (for example, you can set the uac-BarringFactor of other cells to be 0, that is, assuming that the UAC information of other cells prohibits access requests based on at least one pre-judged access identifier and at least one pre-judged access category, then no further Consider other cells), so that the checking and comparison process can be reduced, and the efficiency of determining the cell to be resided can be improved.
302b、终端设备在该至少一个第一小区中不包括第一目标小区，但包括第二目标小区的情况下，将第二目标小区确定为该待驻留小区。302b. If the at least one first cell does not include the first target cell but includes the second target cell, the terminal device determines the second target cell as the cell to camp on.
其中，第二目标小区为该至少一个第一小区中，UAC信息允许基于该至少一个预判接入标识和第一预判接入类别的接入请求的概率最高的小区(即与接入需求匹配程度最高的小区)；其中，第一预判接入类别为该至少一个预判接入类别中的一个。Wherein, the second target cell is the cell of the at least one first cell, and the UAC information allows the cell with the highest probability of an access request based on the at least one pre-judged access identifier and the first pre-judged access category (that is, the cell with the highest probability of access request based on the access requirement). The cell with the highest matching degree); wherein, the first predicted access category is one of the at least one predicted access category.
可选地，第一预判接入类别可以为该至少一个预判接入类别中的任意一个，第一预判接入类别也可以为该至少一个预判接入类别中当前终端设备最需要的一个(当前终端设备最重要的接入请求对应的接入类别)，第一预判接入类别还可以为该至少一个预判接入类别中满足其他可行性条件的一个，本申请实施例不做限定。Optionally, the first predicted access category may be any one of the at least one predicted access category, and the first predicted access category may also be the current terminal device in the at least one predicted access category. (the access category corresponding to the most important access request of the current terminal device), the first pre-judged access category may also be one of the at least one pre-judged access category that satisfies other feasibility conditions, the embodiment of the present application No limit.
本申请实施例中，在该至少一个第一小区中不存在第一目标小区，存在第二目标小区的情况下，将与接入需求匹配程度最高的第二目标小区确定为待驻留小区进行驻留，在进行注册或发起业务时UAC检查被禁止可能性较小，如此，可以提高终端设备的入网效率。In the embodiment of the present application, if there is no first target cell in the at least one first cell and there is a second target cell, the second target cell with the highest degree of matching with the access requirement is determined as the cell to be camped on. Residing, the UAC check is less likely to be prohibited when registering or initiating services, so that the network access efficiency of terminal devices can be improved.
本申请实施例中，终端设备可以根据自身接入需求，为该每个预判接入类别设置优先级。则上述其他可行性条件包括以下两种可能的情况：In this embodiment of the present application, the terminal device may set a priority for each pre-judged access category according to its own access requirements. The above-mentioned other feasibility conditions include the following two possible situations:
第一种可能的情况，第一预判接入类别为该至少一个预判接入类别中优先级最高的接入类别。In a first possible situation, the first predicted access category is an access category with the highest priority among the at least one predicted access category.
第二种可能的情况，第一预判接入类别为该至少一个预判接入类别中，除第二预判接入类别之外优先级最高的接入类别；其中，至少两个第一小区的UAC信息允许基于该至少一个预判接入标识和第二预判接入类别的接入请求的概率最高，该至少两个第一小区包括第二目标小区。In the second possible situation, the first predicted access category is the access category with the highest priority except the second predicted access category among the at least one predicted access category; wherein, at least two first The UAC information of the cell allows the highest probability of an access request based on the at least one pre-judged access identifier and the second pre-judged access category, and the at least two first cells include the second target cell.
可以理解，本申请实施例中，按照预判接入类别的优先级从高到低，依次判断每个第一小区与每个预判接入类别对应的接入需求的匹配程度，例如，先判断每个第一小区与优先级最高的预判接入类别对应的接入需求的匹配程度，若每个第一小区与优先级最高的预判接入类别对应的接入需求的匹配程度不同，则将与优先级最高的预判接入类别对应的接入需求的匹配程度最高的小区确定为第二目标小区；若该至少一个第一小区中存在至少两个小区，与优先级最高的预判接入类别对应的接入需求的匹配程度相同(且最高)，则再判断该至少两个小区中每个小区与优先级次高的预判接入类别对应的接入需求的匹配程度，依次类推，得到第二目标小区。It can be understood that in this embodiment of the present application, according to the priorities of the pre-judged access categories from high to low, the degree of matching of each first cell with the access requirements corresponding to each pre-judged access category is judged sequentially, for example, first Determine the matching degree of each first cell with the access requirements corresponding to the highest priority pre-judged access category, if the matching degree of each first cell with the highest priority pre-judged access category , then determine the cell with the highest matching degree of access requirements corresponding to the highest priority predicted access category as the second target cell; if there are at least two cells in the at least one first cell, the cell with the highest priority If the matching degree of access requirements corresponding to the predicted access category is the same (and the highest), then judge the matching degree of the access requirement corresponding to each cell in the at least two cells and the predicted access category with the second highest priority , and so on, to obtain the second target cell.
下面以第一预判接入标识为例，描述如何判断每个第一小区与该至少一个预判接入标识和第一预判接入类别对应的接入需求的匹配程度。The following takes the first pre-judged access identifier as an example to describe how to judge the matching degree of each first cell with the access requirements corresponding to the at least one pre-judged access identifier and the first pre-judged access category.
按照第一预判接入类别对应的实际UAC禁止接入因子(uac-BarringFactor)筛选：如果第一预判接入类别存在对应的UAC接入禁止集(uac-BarringInfoSet)，且所有预判接入标识(即该至少一个预判接入标识)对应的UAC禁止访问标识(uac-BarringForAccessIdentity)的比特(bit)位均为1，或者所有预判接入标识均不再uac-BarringForAccessIdentity中，则uac-BarringFactor最大的第一小区为与(该至少一个预判接入标识和第一预判接入类别)对应的接入需求的匹配程度最高的小区；如果第一预判接入类别不存在对应的UAC-BarringInfoSet，或者虽然存在UAC-BarringInfoSet，但本次传入的所有预判接入标识对应的uac-BarringForAccessIdentity的bit位中至少有一个为0，则第一小区对第一预判接入类别UAC检查为允许，可以认为其对应的uac-BarringFactor为1，则第一小区为与(该至少一个预判接入标识和第一预判接入类别)对应的接入需求的匹配程度最高的小区。Filter according to the actual UAC barring factor (uac-BarringFactor) corresponding to the first pre-judged access category: if there is a corresponding UAC access barring set (uac-BarringInfoSet) for the first pre-judged access category, and all pre-judged access The bit (bit) of the UAC barring access identification (uac-BarringForAccessIdentity) corresponding to the incoming identification (that is, the at least one pre-judged access identification) is 1, or all the pre-judged access identifications are no longer in uac-BarringForAccessIdentity, then The first cell with the largest uac-BarringFactor is the cell with the highest degree of matching with the access requirements corresponding to (the at least one pre-judged access identifier and the first pre-judged access category); if the first pre-judged access category does not exist The corresponding UAC-BarringInfoSet, or although there is a UAC-BarringInfoSet, but at least one of the bits of uac-BarringForAccessIdentity corresponding to all pre-judgment access identities passed in this time is 0, the first cell’s first pre-judgment access If the entry type UAC check is allowed, it can be considered that the corresponding uac-BarringFactor is 1, then the first cell is the matching degree of the access requirement corresponding to (the at least one pre-judged access identifier and the first pre-judged access category) highest neighborhood.
需要说明的是，uac-BarringFactor的取值范围为[0,1]，uac-BarringFactor值为0表示禁止接入，uac-BarringFactor值为1表示允许接入，uac-BarringFactor值越高，表示允许接入的可能性越大。uac-BarringForAccessIdentity的bit位为0或1，uac-BarringForAccessIdentity的bit位为0表示允许接入，uac-BarringForAccessIdentity的bit位为1表示禁止接入。It should be noted that the value range of uac-BarringFactor is [0,1]. A uac-BarringFactor value of 0 means that access is prohibited, a uac-BarringFactor value of 1 means access is allowed, and a higher value of uac-BarringFactor means that access is allowed. Access is more likely. The bit of uac-BarringForAccessIdentity is 0 or 1, the bit of uac-BarringForAccessIdentity is 0, which means access is allowed, and the bit of uac-BarringForAccessIdentity is 1, which means access is prohibited.
多个小区均条件相同时(即多个小区对于某接入类别的uac-BarriingFactor相同)，则继续查看是否满足次高优先级接入类别，依次类推，选择当前环境下与接入类别列表匹配度最高的小区进行驻留，发送PlmnSearchCnf(部分搜网成功，该小区UAC信息，搜索到的其他PLMN及其UAC信息)。When multiple cells have the same conditions (that is, multiple cells have the same uac-BarriingFactor for a certain access category), continue to check whether the access category with the second highest priority is satisfied, and so on, select the current environment to match the access category list Camp in the cell with the highest degree, and send PlmnSearchCnf (partial network search is successful, UAC information of this cell, other PLMNs and their UAC information found in the search).

可选地，在确定第四PLMN下存在第五目标小区的情况下，第二选项还用于指示更换为第四PLMN重新搜网。Optionally, in a case where it is determined that there is a fifth target cell under the fourth PLMN, the second option is also used to instruct to change to the fourth PLMN and re-search the network.
其中，第四PLMN的优先级低于预设优先级；第五目标小区的UAC信息允许基于至少一个接入标识和至少一个接入类别中的每个接入类别的接入请求；该至少一个接入标识与第四PLMN对应。Wherein, the priority of the fourth PLMN is lower than the preset priority; the UAC information of the fifth target cell allows an access request based on at least one access identifier and each access category in at least one access category; the at least one The access identifier corresponds to the fourth PLMN.
本申请实施例中，第四PLMN为优先级较低的PLMN，即从高优先级的第一PLMN更换到低优先级的第四PLMN，但第四PLMN下存在完全符合接入需求(基于至少一个接入标识和至少一个接入类别中的每个接入类别的接入请求)的第五目标小区。则终端设备更换到第四PLMN重新搜网，可以驻留在第五目标小区，进而基于至少一个接入标识和至少一个接入类别中的每个接入类别的接入请求，不会因UAC检查被禁止。In the embodiment of this application, the fourth PLMN is a PLMN with a lower priority, that is, the first PLMN with high priority is replaced with the fourth PLMN with low priority, but there are PLMNs under the fourth PLMN that fully meet the access requirements (based on at least An access identifier and an access request for each of the at least one access category) a fifth target cell. Then the terminal device changes to the fourth PLMN to search the network again, and can reside in the fifth target cell, and then based on at least one access identifier and at least one access category access request, it will not be affected by UAC Inspection is prohibited.
本申请实施例中，因为更换到低优先级的PLMN，可能会产生资费，但可以提高网络速率，快速改善网络拥塞问题，因此根据用户需求确定是否更换至第四PLMN重新搜网，可以提高人机交互性能。In the embodiment of this application, due to switching to a low-priority PLMN, tariffs may be incurred, but the network rate can be increased, and the network congestion problem can be quickly improved. Therefore, it is determined whether to switch to the fourth PLMN to search the network again according to user needs, which can improve people. computer interaction performance.
可选地，在该目标接入类别属于该至少一个预判接入类别的情况下，该至少一个接入类别为该至少一个预判接入类别。Optionally, when the target access category belongs to the at least one pre-judged access category, the at least one access category is the at least one pre-judged access category.
可选地，在该目标接入类别不属于该至少一个预判接入类别的情况下，该至少一个接入类别为该至少一个预判接入类别和该目标接入类别。Optionally, when the target access category does not belong to the at least one pre-judged access category, the at least one access category is the at least one pre-judged access category and the target access category.
可以理解，若目标接入类别为终端设备发起的新业务请求对应的接入类别，不在该至少一个预判接入类别中(即在驻留在待驻留小区之后，接入类别发生变化)，则该至少一个接入类别为该至少一个预判接入类别和该目标接入类别；否则，该至少一个接入类别为该至少一个预判接入类别。It can be understood that if the target access category is the access category corresponding to the new service request initiated by the terminal device, it is not in the at least one pre-judged access category (that is, after camping in the cell to be camped on, the access category changes) , then the at least one access category is the at least one predicted access category and the target access category; otherwise, the at least one access category is the at least one predicted access category.
本申请实施例中，根据实际业务需求，更新该至少一个预判接入类别，从而可以在后续搜网中，获得满足当前接入需求的小区进行驻留。In this embodiment of the present application, the at least one pre-judged access category is updated according to actual service requirements, so that a cell that meets the current access requirements can be obtained for camping in a subsequent network search.
示例性地，下面分4种场景对驻留在待驻留小区之后的流程进行说明。Exemplarily, the process of camping on the cell to be camped on is described below in four scenarios.
场景1：搜网成功，搜网结束，终端设备驻留在第一目标小区，继续执行后续的注册请求或业务请求流程。该场景通常情况下，不会出现UAC检查禁止。Scenario 1: The network search is successful, the network search ends, the terminal device resides in the first target cell, and continues to execute the subsequent registration request or service request process. In this scenario, under normal circumstances, UAC check prohibition does not occur.
场景2：部分搜网成功，搜网结束，终端设备驻留在第二目标小区，由于搜网时的UAC禁止是初步判断，则可以给后续的注册请求或者业务请求一次机会，发起注册请求或者业务请求。Scenario 2: Part of the network search is successful, the network search is completed, and the terminal device resides in the second target cell. Since the UAC prohibition during the network search is a preliminary judgment, you can give the subsequent registration request or service request a chance to initiate a registration request or business request.
场景2.1，AS进行UAC检查，如果UAC检查结果依然为禁止，当前注册请求或者业务请求不能进行，此时AS可以在当前PLMN下进行小区重选，如果选到更优的小区，则在该更优的小区进行驻留，并将驻留后的结果上报给NAS；如果未选到更优的小区，则AS向NAS上报UAC检查结果，该UAC检查结果中可以包括其他可能满足要求的备选PLMN，此时需要NAS更换PLMN。若相同优先级的PLMN间，存在满足一定接入需求的第五PLMN，则NAS重新选择第五PLMN，并通知AS进行第五PLM+UAC信息的搜网流程；若仅存在优先级低于当前驻留的PLMN的第六PLMN，则终端设备显示提示信息，提示用户当前网络状态处于拥塞，无法入网或者进行某业务(被阻塞的业务)，请用户进行选择，是否需要更换网络尝试，即提示用户是否切换到第六PLMN重新搜网，并在拥塞期间保存用户选择(在本次拥塞解决前，保存用户选择，在本次拥塞解决后，删除用户选择)。如果用户选择在原网络等待，本次搜网结束，后续按照现有流程继续执行。如果用户选择更换网络尝试，则NAS重新选择第六PLMN，并通知AS再次执行第六PLMN+UAC信息搜网。当第一PLMN不能完全满足接入需求时，在用户同意的情况下，更换其他网络进行尝试。Scenario 2.1, the AS performs a UAC check. If the result of the UAC check is still prohibited, the current registration request or service request cannot be performed. At this time, the AS can perform cell reselection under the current PLMN. The optimal cell will be camped on, and the result will be reported to the NAS; if no better cell is selected, the AS will report the UAC check result to the NAS, and the UAC check result can include other alternatives that may meet the requirements PLMN. In this case, the NAS needs to replace the PLMN. If there is a fifth PLMN that meets certain access requirements among PLMNs with the same priority, the NAS reselects the fifth PLMN and notifies the AS to search the network for the fifth PLM+UAC information; For the sixth PLMN of the resident PLMN, the terminal device displays a prompt message, prompting the user that the current network status is congested, unable to access the network or perform a certain service (blocked service), ask the user to make a choice, whether to try to change the network, that is, prompt Whether the user switches to the sixth PLMN to search the network again, and save the user selection during the congestion period (save the user selection before the congestion is resolved, and delete the user selection after the congestion is resolved). If the user chooses to wait in the original network, the current network search is over, and the subsequent execution will continue according to the existing process. If the user chooses to try to change the network, the NAS reselects the sixth PLMN, and notifies the AS to perform the sixth PLMN+UAC information search network again. When the first PLMN cannot fully meet the access requirements, with the consent of the user, another network is tried.
