具体实施方式Detailed ways

图1a示出了目前移动通信网络的基本架构，移动通信网络中包括：用户设备101、接入网设备102以及核心网设备103。其中，接入网设备的数量为多个，多个接入网设备整体构成了移动通信网络中的接入网；核心网设备通常为一个或多个，一个或多个接入网设备整体构成了移动通信网络中的核心网。接入网设备，具体可以是基站，用于提供无线覆盖以及连接用户设备和核心网。在4G网络中，接入网设备包括eNB(evolved NobeB，演进基站)，核心网设备包括：MME(Mobility Management Entity，移动管理实体)设备。在5G网络中，接入网设备包括GNB(next generation NobeB，下一代基站)，核心网设备包括：AMF(Accessand Mobility Management Function，接入和移动性管理功能)设备。Figure 1a shows the basic architecture of the current mobile communication network, which includes: user equipment 101, access network equipment 102 and core network equipment 103. Among them, the number of access network devices is multiple, and the multiple access network devices as a whole constitute the access network in the mobile communication network; the core network device is usually one or more, and one or more access network devices as a whole constitute the core network in the mobile communication network. The access network device, which can be specifically a base station, is used to provide wireless coverage and connect user equipment and the core network. In the 4G network, the access network equipment includes eNB (evolved NobeB), and the core network equipment includes: MME (Mobility Management Entity) equipment. In the 5G network, the access network equipment includes GNB (next generation NobeB), and the core network equipment includes: AMF (Access and Mobility Management Function) equipment.

其中，接入网设备与核心网设备之间需建立接口连接，例如：在4G网络中，基站与核心网设备之间需建立S1接口连接；在5G网络中，基站与核心网设备之间需建立NG接口连接。S1是基站和MME之间交换应用层配置数据的接口的名称。S1连接的建立意味着eNB和MME之间之前已经存在的所有应用层数据将被全部清空，所有的数据将被重新建立。NG接口是基站和AMF之间交换应用程序级别配置数据的接口的名称。NG连接的建立意味着将擦除两个节点中的现有应用程序级别配置数据，并将其替换为接收到的数据，并清除基站上的AMF超载状态信息。Among them, an interface connection needs to be established between the access network equipment and the core network equipment. For example, in the 4G network, an S1 interface connection needs to be established between the base station and the core network equipment; in the 5G network, an NG interface connection needs to be established between the base station and the core network equipment. S1 is the name of the interface for exchanging application layer configuration data between the base station and the MME. The establishment of the S1 connection means that all application layer data that previously existed between the eNB and the MME will be cleared and all data will be re-established. The NG interface is the name of the interface for exchanging application level configuration data between the base station and the AMF. The establishment of the NG connection means that the existing application level configuration data in the two nodes will be erased and replaced with the received data, and the AMF overload status information on the base station will be cleared.

用户设备在开机、丢网或用户关闭飞行模式时，需要进行驻网过程，也即搜网过程。驻网过程也即是找到合适的小区进行驻留。用户设备驻网成功后，才能够通过该移动通信网络进行通讯。When the user device is turned on, loses the network, or the user turns off the flight mode, it needs to go through the network stationing process, that is, the network search process. The network stationing process is to find a suitable cell to stay in. Only after the user device successfully stays in the network can it communicate through the mobile communication network.

现有技术中，用户设备在开机、丢网或用户关闭飞行模式时，需要针对用户设备所支持的所有频段进行扫描。而目前大部分用户设备能够支持几十多个频段，往后也许更多，若采用全频段扫描的方式来驻网，会出现耗时较长的问题。In the prior art, when the user device is turned on, loses the network, or the user turns off the flight mode, it is necessary to scan all the frequency bands supported by the user device. At present, most user devices can support more than dozens of frequency bands, and there may be more in the future. If the full frequency band scanning method is used to stay on the network, it will take a long time.

此外，现有技术中，如图1b和1c所示，接入网设备(图1b中的eNB1021或图1c中的NG-RAN node1022)需要入网时，主动向核心网设备(图1b中的MME1031或图1c中的AFM1032)发送接口连接建立请求(例如：S1SETUP REQUEST或NGSETUP REQUEST)，核心网设备接收到接口连接建立请求后，根据接口连接建立请求中携带的内容确定是否同意该接入网设备接入，若同意，则向接入网设备(图1b中的eNB1021或图1c中的NG-RAN node1022)返回接口连接建立响应信息(例如：S1SETUP RESPONSE或NG SETUP RESPONSE)，接口连接建立成功；若不同意则向接入网设备返回接口连接建立失败信息(S1setup failure或NG setupfailure)。当核心网设备需重启或需替换时，接入网设备发出接口连接建立请求后将会得不到任何回应，只能周期性地尝试着发送接口连接建立请求，也即每隔预设时间间隔(例如：1min)尝试着发送接口连接建立请求。也就是说，在这种情况下，即使核心网设备状态准确完成，接入网设备还是需要等到定时器轮训到才能够发送S1SETUP REQUEST或NG SETUPREQUEST给核心网设备，无法及时建立接口连接，存在效率低的问题。In addition, in the prior art, as shown in Figures 1b and 1c, when the access network device (eNB1021 in Figure 1b or NG-RAN node1022 in Figure 1c) needs to access the network, it actively sends an interface connection establishment request (for example, S1SETUP REQUEST or NGSETUP REQUEST) to the core network device (MME1031 in Figure 1b or AFM1032 in Figure 1c). After receiving the interface connection establishment request, the core network device determines whether to agree to the access of the access network device according to the content carried in the interface connection establishment request. If agreed, the interface connection establishment response information (for example, S1SETUP RESPONSE or NG SETUP RESPONSE) is returned to the access network device (eNB1021 in Figure 1b or NG-RAN node1022 in Figure 1c), and the interface connection is successfully established; if not agreed, the interface connection establishment failure information (S1setup failure or NG setupfailure) is returned to the access network device. When the core network device needs to be restarted or replaced, the access network device will not receive any response after sending an interface connection establishment request, and can only periodically try to send an interface connection establishment request, that is, try to send an interface connection establishment request every preset time interval (for example: 1min). In other words, in this case, even if the core network device status is accurately completed, the access network device still needs to wait until the timer rotation is reached before it can send S1SETUP REQUEST or NG SETUPREQUEST to the core network device, and the interface connection cannot be established in time, resulting in low efficiency.

蜂窝网络中将服务区划分为若干个彼此相邻的小区，每个小区设立一个基站，每个小区呈正六边形。In a cellular network, the service area is divided into several adjacent cells, each of which has a base station and is in the shape of a regular hexagon.

图2示出了本申请一实施例提供的通信方法的流程示意图。所述方法适用于移动通信网络中的核心网设备。也即该方法的执行主体为移动通信网络中的网络设备。在一实例中，网络设备可以为核心网设备；在另一实例中，网络设备可以为接入网设备，若为接入网设备，接入网设备可从核心网设备处获取移动通信网络对应的频段信息，可以是主动获取或者是被动获取，被动获取也即是由核心网设备主动将移动通信网络对应的频段信息发送给接入网设备，接入网设备接收到所述移动通信网络对应的频段信息后，将其转发给用户设备。下文将以网络设备为核心网设备进行举例介绍。如图2所示，该方法包括：FIG2 shows a flow chart of a communication method provided by an embodiment of the present application. The method is applicable to a core network device in a mobile communication network. That is, the executor of the method is a network device in a mobile communication network. In one example, the network device may be a core network device; in another example, the network device may be an access network device. If it is an access network device, the access network device may obtain the frequency band information corresponding to the mobile communication network from the core network device. The acquisition may be active or passive. Passive acquisition means that the core network device actively sends the frequency band information corresponding to the mobile communication network to the access network device. After the access network device receives the frequency band information corresponding to the mobile communication network, it forwards it to the user device. The following will take the network device as a core network device as an example. As shown in FIG2, the method includes:

201、获取所述移动通信网络对应的频段信息。201. Obtain frequency band information corresponding to the mobile communication network.

202、将所述移动通信网络对应的频段信息发送给用户设备，以由所述用户设备将所述移动通信网络对应的频段信息进行存储，以便重新驻网时参考。202. Send the frequency band information corresponding to the mobile communication network to the user equipment, so that the user equipment stores the frequency band information corresponding to the mobile communication network for reference when re-stationing on the network.

上述201中，所述移动通信网络对应的频段信息指的是该移动通信网络所使用的频段的频段信息。不同运营商的移动通信网络所使用的频段不同。In the above 201, the frequency band information corresponding to the mobile communication network refers to the frequency band information of the frequency band used by the mobile communication network. The frequency bands used by mobile communication networks of different operators are different.

上述移动通信网络具体可以为公共陆地移动通信网络(Public Land MobileNetwork，简称：PLMN)。The above-mentioned mobile communication network may specifically be a public land mobile communication network (Public Land Mobile Network, abbreviated as: PLMN).

获取移动通信网络对应的频段信息，也即是获取移动通信网络当前所使用的所有频段的频段信息。频段信息可包括频段号。Acquiring the frequency band information corresponding to the mobile communication network means acquiring the frequency band information of all frequency bands currently used by the mobile communication network. The frequency band information may include the frequency band number.

上述202中，上述用户设备指的是在上述移动通信网络中已驻网成功的用户设备，这样核心网设备才能够向给用户设备发送信息。In the above 202, the above user equipment refers to a user equipment that has successfully settled in the above mobile communication network, so that the core network device can send information to the user equipment.

用户设备将接收到的移动通信网络对应的频段信息进行存储，例如：可存储在用户设备本地或存储在安装在用户设备上的SIM(Subscriber Identity Module)卡中。需要说明的是，上述存储是永久性存储，掉电不丢失。The user equipment stores the received frequency band information corresponding to the mobile communication network, for example, locally in the user equipment or in a SIM (Subscriber Identity Module) card installed in the user equipment. It should be noted that the above storage is permanent storage and will not be lost when power is off.

上述核心网设备可在所述用户设备在所述移动通信网络中驻网成功后，将所述移动通信网络对应的频段信息发送给所述用户设备，和/或，上述核心网设备在所述移动通信网络对应的频段信息更新后，将更新后的所述移动通信网络对应的频段信息发送给所述用户设备。The above-mentioned core network device may send the frequency band information corresponding to the mobile communication network to the user equipment after the user equipment successfully stations in the mobile communication network, and/or, after the frequency band information corresponding to the mobile communication network is updated, the above-mentioned core network device may send the updated frequency band information corresponding to the mobile communication network to the user equipment.

假设用户设备在存储好核心网设备发送的移动通信网络对应的频段信息后，用户设备因故障关机后重启，重启之后需执行驻网流程，在驻网流程中，用户设备可从本地或SIM卡中读取出存储的上一次驻网成功的移动通信网络对应的频段信息，根据该频段信息，可确定出移动通信网络所使用的频段，针对该频段进行扫描，以搜索适合驻留的小区，以完成驻网。通常而言，用户设备很少会更换SIM卡，也即很少更换移动通信网络，那么，基于上一次驻网成功的移动通信网络对应的频段信息进行驻网，是能够驻网成功的，减少了驻网耗时，提高了用户使用体验。Assume that after the user equipment stores the frequency band information corresponding to the mobile communication network sent by the core network equipment, the user equipment is shut down due to a fault and then restarted. After the restart, the network stationing process needs to be executed. In the network stationing process, the user equipment can read the frequency band information corresponding to the mobile communication network that was successfully stationed last time from the local or SIM card. According to the frequency band information, the frequency band used by the mobile communication network can be determined, and the frequency band is scanned to search for a cell suitable for stationing to complete the network stationing. Generally speaking, user equipment rarely changes SIM cards, that is, rarely changes mobile communication networks. Therefore, it is possible to successfully station on the network based on the frequency band information corresponding to the mobile communication network that was successfully stationed last time, which reduces the time consumed in stationing on the network and improves the user experience.

本申请实施例提供的技术方案中，移动通信网络中的核心网设备将移动通信网络对应的频段信息发送给在该移动通信网络中已驻网成功的用户设备，用户设备将该移动通信网络对应的频段信息进行存储。这样，该用户设备后续开机、丢网或用户关闭飞行模式时，结合该移动通信网络对应的频段信息进行驻网，相比于现有技术中需针对该用户设备所支持的所有频段进行全频段扫描，可提高驻网速度，降低驻网耗时。In the technical solution provided by the embodiment of the present application, the core network device in the mobile communication network sends the frequency band information corresponding to the mobile communication network to the user equipment that has successfully settled in the mobile communication network, and the user equipment stores the frequency band information corresponding to the mobile communication network. In this way, when the user equipment is subsequently turned on, loses the network, or the user turns off the flight mode, it settles in the network in combination with the frequency band information corresponding to the mobile communication network. Compared with the prior art that requires full frequency band scanning for all frequency bands supported by the user equipment, the settlement speed can be increased and the settlement time can be reduced.

进一步的，所述移动通信网络对应的频段信息包括目标跟踪区对应的频段信息；其中，所述目标跟踪区指的是所述用户设备当前所在的跟踪区。上述202中“将所述移动通信网络对应的频段信息发送给用户设备”，具体可包括：Furthermore, the frequency band information corresponding to the mobile communication network includes frequency band information corresponding to a target tracking area; wherein the target tracking area refers to the tracking area where the user equipment is currently located. In the above 202, "sending the frequency band information corresponding to the mobile communication network to the user equipment" may specifically include:

2021a、将所述目标跟踪区对应的频段信息发送给所述用户设备。2021a. Send the frequency band information corresponding to the target tracking area to the user equipment.

用户设备当前所在的跟踪区可通过跟踪区更新(Tracking Area Update,TAU)过程来确定。其中，跟踪区更新过程指的是当移动台(也即用户设备)由一个跟踪区TA(Tracking Area)移动到另一个TA时，必须在新的TA上重新进行位置登记以通知网络来更改它所存储的移动台的位置信息。注：一个跟踪区内可设有多个小区，例如：几十个小区。The current tracking area of the user equipment can be determined through the Tracking Area Update (TAU) process. The Tracking Area Update process means that when a mobile station (that is, user equipment) moves from one Tracking Area (TA) to another TA, it must re-register its location on the new TA to notify the network to change the location information of the mobile station it stores. Note: There can be multiple cells in a tracking area, for example: dozens of cells.

目标跟踪区对应的频段信息指的是目标跟踪区所使用的所有频段的频段信息。通常，跟踪区所使用的频段具体指的是跟踪区内的至少一个接入网设备所使用的频段，不同跟踪区所使用的频段不同，一个跟踪区也并非使用了移动通信网络所使用的所有频段。例如：移动通信网络所使用的频段有band1、band2、band3和bang4，该移动通信网络中的第一跟踪区所使用的频段有band1和band2，第二跟踪区所使用的频段有band3和bang4。The frequency band information corresponding to the target tracking area refers to the frequency band information of all frequency bands used by the target tracking area. Usually, the frequency band used by the tracking area specifically refers to the frequency band used by at least one access network device in the tracking area. Different tracking areas use different frequency bands, and a tracking area does not use all frequency bands used by the mobile communication network. For example: the frequency bands used by the mobile communication network are band1, band2, band3 and bang4. The frequency bands used by the first tracking area in the mobile communication network are band1 and band2, and the frequency bands used by the second tracking area are band3 and bang4.

在本实施例中，并非是将上述移动通信网络所使用的所有频段的频段信息都发送给用户设备，而是将用户设备当前所在的跟踪区所使用的所有频段的频段信息发送给用户设备。通常，一个跟踪区的范围比较大(例如：一个城市、一个县)，用户在丢网到再次驻网的过程中，用户从一个跟踪区移动到另一个跟踪区的概率比较小，这样，基于用户丢网前所在的跟踪区对应的频段信息进行驻网，成功的概率很大。这样，在保证驻网成功率的基础上，可进一步缩小用户设备在重新驻网时所需扫描的频段范围，进而提高驻网速度。In this embodiment, instead of sending the frequency band information of all the frequency bands used by the mobile communication network to the user equipment, the frequency band information of all the frequency bands used by the tracking area where the user equipment is currently located is sent to the user equipment. Usually, the scope of a tracking area is relatively large (for example, a city or a county). In the process of losing the network and re-locating to the network, the probability of the user moving from one tracking area to another is relatively small. In this way, the probability of success in locating the network based on the frequency band information corresponding to the tracking area where the user was before losing the network is very high. In this way, on the basis of ensuring the success rate of locating to the network, the frequency band range that the user equipment needs to scan when re-locating to the network can be further reduced, thereby improving the speed of locating to the network.

在一实例中，各接入网设备可每隔预设时间间隔向核心网设备发送一次其当前所使用的频段的频段信息。In one example, each access network device may send frequency band information of the frequency band currently used by the access network device to the core network device once every preset time interval.

在另一实例中，各接入网设备可在其与移动通信网络的核心网建立接口连接(也即上线)或者频段更改后，向所述核心网设备发送其所使用的频段的频段信息。这样，核心网设备即能够统计到最小的频段信息，还能够有效降低网络资源开销。In another example, each access network device can send the frequency band information of the frequency band it uses to the core network device after establishing an interface connection with the core network of the mobile communication network (i.e., going online) or changing the frequency band. In this way, the core network device can count the minimum frequency band information and effectively reduce network resource overhead.

在一实例中，上述202中“将所述目标跟踪区对应的频段信息发送给所述用户设备”，可包括如下步骤中的一个或多个：In one example, the “sending the frequency band information corresponding to the target tracking area to the user equipment” in 202 may include one or more of the following steps:

2021b、所述用户设备在所述移动通信网络中驻网成功后，将所述目标跟踪区对应的频段信息发送给所述用户设备。2021b. After the user equipment successfully resides in the mobile communication network, the frequency band information corresponding to the target tracking area is sent to the user equipment.

2021c、所述目标跟踪区对应的频段信息更新后，将更新后的所述目标跟踪区对应的频段信息发送给所述用户设备。2021c. After the frequency band information corresponding to the target tracking area is updated, the updated frequency band information corresponding to the target tracking area is sent to the user equipment.

上述2021b中，具体可以是所述用户设备在所述移动通信网络中驻网成功时，将所述目标跟踪区对应的频段信息发送给所述用户设备。也即是有新用户设备上线时，核心网设备将新用户设备当前所在跟踪区对应的频段信息发送给新用户设备。In the above 2021b, specifically, when the user equipment successfully camps in the mobile communication network, the frequency band information corresponding to the target tracking area is sent to the user equipment. That is, when a new user equipment comes online, the core network device sends the frequency band information corresponding to the tracking area where the new user equipment is currently located to the new user equipment.

上述2021c中，移动通信网络中跟踪区内的某个基站下线、某个基站上线或某个基站的频段发生更改，都有可能会使得相应跟踪区所使用的频段发生更改，一旦跟踪区所使用的频段发生更改，这就导致相应跟踪区对应的频段信息会发生更改。In the above 2021c, if a base station in the tracking area of the mobile communication network goes offline, a base station comes online, or the frequency band of a base station changes, the frequency band used by the corresponding tracking area may change. Once the frequency band used by the tracking area changes, the frequency band information corresponding to the corresponding tracking area will change.

所述目标跟踪区对应的频段信息更新后，将更新后的所述目标跟踪区对应的频段信息发送给所述用户设备。这样，可提高用户设备基于更新后的所述目标跟踪区对应的频段信息进行驻网的成功率，进而降低驻网耗时。After the frequency band information corresponding to the target tracking area is updated, the updated frequency band information corresponding to the target tracking area is sent to the user equipment. In this way, the success rate of the user equipment stationing on the network based on the updated frequency band information corresponding to the target tracking area can be improved, thereby reducing the time consumption of stationing on the network.

进一步的，上述方法，还可包括：Furthermore, the above method may also include:

203、当所述移动通信网络的跟踪区所使用的频段发生改变时，更新所述跟踪区对应的频段信息。203. When a frequency band used by a tracking area of the mobile communication network changes, update frequency band information corresponding to the tracking area.

核心网设备可根据接入网设备发送来的其所使用的频段的频段信息后，进行动态更新各跟踪区对应的频段信息。The core network device can dynamically update the frequency band information corresponding to each tracking area according to the frequency band information of the frequency band used by the access network device.

进一步的，上述方法，还可包括如下步骤中的一个或多个：Furthermore, the above method may further include one or more of the following steps:

204、接收到第一接入网设备发送的其所使用的频段的频段信息后，根据所述第一接入网设备发送的其所使用的频段的频段信息，确定所述第一接入网设备所属跟踪区所使用的频段是否发生改变。204. After receiving the frequency band information of the frequency band used by the first access network device sent by the first access network device, determine whether the frequency band used by the tracking area to which the first access network device belongs has changed according to the frequency band information of the frequency band used by the first access network device sent by the first access network device.

205、所述移动通信网络中第二接入网设备与所述移动通信网络的核心网断开接口连接后，根据所述第二接入网设备在与所述核心网断开接口连接前发送来的其所使用的频段的频段信息，确定所述第二接入网设备所属跟踪区所使用的频段是否发生改变。205. After the second access network device in the mobile communication network disconnects the interface from the core network of the mobile communication network, determine whether the frequency band used by the tracking area to which the second access network device belongs has changed based on the frequency band information of the frequency band used by the second access network device sent before the interface connection with the core network is disconnected.

上述204中，其中，所述第一接入网设备在其与所述移动通信网络的核心网建立接口连接后(也即上线后)或在其频段发生更改后(也即频段更改后)向所述核心网设备发送其所使用的频段的频段信息。In the above 204, the first access network device sends the frequency band information of the frequency band it uses to the core network device after it establishes an interface connection with the core network of the mobile communication network (that is, after going online) or after its frequency band is changed (that is, after the frequency band is changed).

第一接入网设备发送的其所使用的频段的频段信息中还携带有其所属跟踪区的跟踪区信息，这样，可根据第一接入网设备的跟踪区信息，确定该第一接入网设备所属跟踪区。The frequency band information of the frequency band used by the first access network device also carries the tracking area information of the tracking area to which it belongs. In this way, the tracking area to which the first access network device belongs can be determined based on the tracking area information of the first access network device.

根据所述第一接入网设备发送的其所使用的频段的频段信息以及属于第一接入网设备所属跟踪区的其他接入网设备最近一次发送来的频段信息，确定所述第一接入网设备所属跟踪区当前对应的频段信息；将所述第一接入网设备所属跟踪区当前对应的频段信息与上一次确定出的所述第一接入网设备所属跟踪区对应的频段信息做比较，若不同，则说明所述第一接入网设备所属跟踪区所使用的频段发生改变；若相同，则说明所述第一接入网设备所属跟踪区所使用的频段未发生改变。Determine the frequency band information currently corresponding to the tracking area to which the first access network device belongs based on the frequency band information sent by the first access network device and the frequency band information most recently sent by other access network devices belonging to the tracking area to which the first access network device belongs; compare the frequency band information currently corresponding to the tracking area to which the first access network device belongs with the frequency band information corresponding to the tracking area to which the first access network device belongs determined last time; if they are different, it means that the frequency band used by the tracking area to which the first access network device belongs has changed; if they are the same, it means that the frequency band used by the tracking area to which the first access network device belongs has not changed.

举例来说：第一接入网设备所使用的频段有band1和band2，第一接入网设备所属跟踪区还包括第三接入网设备和第四接入网设备，第三接入网设备所使用的频段有band2和band3，第四接入网设备所使用的频段有band4和band5，那么第一接入网设备所属跟踪区当前所使用的频段有band1、band2、band3、band4和band5。上一次确定出的第一接入网设备所属跟踪区所使用的频段有band2、band3、band4和band5，本次确定出的多一个频段band1，不相同，说明第一接入网设备所属跟踪区所使用的频段发生改变。For example: the frequency bands used by the first access network device are band1 and band2, and the tracking area to which the first access network device belongs also includes the third access network device and the fourth access network device. The frequency bands used by the third access network device are band2 and band3, and the frequency bands used by the fourth access network device are band4 and band5. Then the frequency bands currently used by the tracking area to which the first access network device belongs are band1, band2, band3, band4 and band5. The frequency bands used by the tracking area to which the first access network device belongs determined last time are band2, band3, band4 and band5. This time, one more frequency band, band1, is determined, which is different, indicating that the frequency band used by the tracking area to which the first access network device belongs has changed.

上述205、所述移动通信网络中第二接入网设备与所述移动通信网络的核心网断开接口连接后，也即下线后。In the above 205, the second access network device in the mobile communication network disconnects the interface connection with the core network of the mobile communication network, that is, goes offline.

当检测到第二接入网设备与核心网之间的接口连接断开之后，核心网设备可去获取所述第二接入网设备在与所述核心网断开接口连接前发送来的其所使用的频段的频段信息，并根据所述第二接入网设备在与所述核心网断开接口连接前发送来的其所使用的频段的频段信息以及属于所述第二接入网设备所属跟踪区的其他接入网设备最近一次发送来的频段信息，确定所述第二接入网设备所属跟踪区所使用的频段是否发生改变。After detecting that the interface connection between the second access network device and the core network is disconnected, the core network device may obtain the frequency band information of the frequency band used by the second access network device sent by the second access network device before the interface connection with the core network is disconnected, and determine whether the frequency band used by the tracking area to which the second access network device belongs has changed based on the frequency band information of the frequency band used by the second access network device sent by the second access network device before the interface connection with the core network is disconnected and the frequency band information most recently sent by other access network devices belonging to the tracking area to which the second access network device belongs.

举例来说：第二接入网设备下线之前所使用的频段有band1和band2，第二接入网设备所属跟踪区还包括第五接入网设备和第六接入网设备，第五接入网设备所使用的频段有band2和band3，第四接入网设备所使用的频段有band4和band5，由于第二接入网设备下线了，那么第二接入网设备所属跟踪区当前所使用的频段有band2、band3、band4和band5。上一次确定出的第一接入网设备所属跟踪区所使用的频段有band1、band2、band3、band4和band5，也即本次确定出的少一个频段band1，不相同，说明第二接入网设备所属跟踪区所使用的频段发生改变。For example: the frequency bands used by the second access network device before it goes offline are band1 and band2, and the tracking area to which the second access network device belongs also includes the fifth access network device and the sixth access network device, the frequency bands used by the fifth access network device are band2 and band3, and the frequency bands used by the fourth access network device are band4 and band5. Since the second access network device is offline, the frequency bands currently used by the tracking area to which the second access network device belongs are band2, band3, band4 and band5. The frequency bands used by the tracking area to which the first access network device belongs determined last time are band1, band2, band3, band4 and band5, that is, one less frequency band, band1, is determined this time, which is different, indicating that the frequency band used by the tracking area to which the second access network device belongs has changed.

实际应用中，如图3所示，各接入网设备可在上线，或者基站频段更改时，将其所使用的频段的频段信息发送给核心网设备(对应步骤301)，核心网设备接收到各接入网设备所使用的频段的频段信息之后，可更新各跟踪区对应的频段信息(对应步骤302)。各接入网设备还可将其设备信息和/或跟踪区信息发送给核心网设备，以便核心网设备统计。设备信息可包括设备标识，跟踪区信息可包括跟踪区标识，例如：TAC(Tracking Area Code，跟踪区编号)。当然，各接入网设备可只将其设备信息发送给核心网设备，核心网设备根据各接入网设备的设备信息以及事先存储的接入网设备的设备信息与所属跟踪区的跟踪区信息之间的对应关系，确定出各接入网设备所属的跟踪区。当TAC1的频段集有更新，核心网设备向TAC1下所在基站的所有UE下发消息：[TAC1：频段A、频段B、频段C、频段Z](对应于步骤303)。当TAC1下，有新UE上线，核心网向该UE下发TAC1的频段集信息：[TAC1：频段A、频段B、频段C、频段Z](对应于步骤303)。接入网设备存储[TAC1：频段A、频段B、频段C、频段Z](对应于步骤304)。In actual application, as shown in FIG3, each access network device can send the frequency band information of the frequency band used by it to the core network device when it goes online or the base station frequency band is changed (corresponding to step 301). After receiving the frequency band information of the frequency band used by each access network device, the core network device can update the frequency band information corresponding to each tracking area (corresponding to step 302). Each access network device can also send its device information and/or tracking area information to the core network device for the core network device to count. The device information may include a device identifier, and the tracking area information may include a tracking area identifier, such as TAC (Tracking Area Code). Of course, each access network device can only send its device information to the core network device, and the core network device determines the tracking area to which each access network device belongs based on the device information of each access network device and the correspondence between the device information of the access network device stored in advance and the tracking area information of the tracking area to which it belongs. When the frequency band set of TAC1 is updated, the core network device sends a message to all UEs of the base station under TAC1: [TAC1: frequency band A, frequency band B, frequency band C, frequency band Z] (corresponding to step 303). When a new UE comes online under TAC1, the core network sends the frequency band set information of TAC1 to the UE: [TAC1: frequency band A, frequency band B, frequency band C, frequency band Z] (corresponding to step 303). The access network device stores [TAC1: frequency band A, frequency band B, frequency band C, frequency band Z] (corresponding to step 304).

在本实施例中，核心网设备需要将移动通信网络对应的频段信息或目标跟踪区对应的频段信息发送给相应的接入网设备，以由相应的接入网设备转发给用户设备。In this embodiment, the core network device needs to send the frequency band information corresponding to the mobile communication network or the frequency band information corresponding to the target tracking area to the corresponding access network device, so that the corresponding access network device forwards it to the user equipment.

If the network stationing based on the historical frequency band is successful, the above steps 203 and 404 do not need to be performed.

Improving the stationing speed, especially for driverless cars that are driving, can help improve driving safety.

601、获取所述核心网设备的状态信息。601. Obtain status information of the core network device.

602、根据所述状态信息，生成通知信息。602. Generate notification information according to the status information.

603、将所述通知信息发送给所述移动通信网络中的目标接入网设备，以由所述目标接入网设备在请求建立接口连接时参考。603. Send the notification information to a target access network device in the mobile communication network, so that the target access network device can refer to it when requesting to establish an interface connection.

上述601中，核心网设备的状态信息用于表明该核心网设备是否具备建立接口连接所需的条件。在一实例中，所述核心网设备的状态信息可包括：所述核心网设备上的与建立接口连接相关的进程的运行状态信息以及所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态信息。所述核心网设备上的与建立接口连接相关的进程的运行状态正常且所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态为互通状态时，说明该核心网设备具备建立接口连接所需的条件。所述核心网设备上的与建立接口连接相关的进程的运行状态不正常或所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态不互通时，说明该核心网设备不具备建立接口连接所需的条件。In the above 601, the status information of the core network device is used to indicate whether the core network device has the conditions required to establish an interface connection. In one example, the status information of the core network device may include: the running status information of the process related to establishing the interface connection on the core network device and the connection status information of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network. When the running status of the process related to establishing the interface connection on the core network device is normal and the connection status of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network is an intercommunication state, it means that the core network device has the conditions required to establish the interface connection. When the running status of the process related to establishing the interface connection on the core network device is abnormal or the connection status of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network is not intercommunication, it means that the core network device does not have the conditions required to establish the interface connection.

在一实例中，可在所述核心网设备启动后，获取所述核心网设备上的与建立接口连接相关的进程的启动状态以及所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态。In one example, after the core network device is started, the startup status of the process related to establishing an interface connection on the core network device and the connection status of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network can be obtained.

在一实例中，上述601中，通知信息可包括上述状态信息，这样，可由接入网设备根据该状态信息，来确定该核心网设备是否具备建立接口连接所需的条件。In one example, in the above 601, the notification information may include the above status information, so that the access network device can determine whether the core network device has the conditions required to establish an interface connection based on the status information.

在另一实例中，上述601中，通知信息可包括可建通知信息或不可建通知信息。在一实例中，所述状态信息表明该核心网设备具备建立接口连接所需的条件时，生成可建通知信息。在另一实例中，所述状态信息表明该核心网设备不具备建立接口连接所需的条件时(通常，是所述核心网设备上的与建立接口连接相关的进程的启动状态不正常，但是所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态是互通的)，生成不可建通知信息。In another example, in the above 601, the notification information may include a notification information that can be established or a notification information that cannot be established. In one example, when the status information indicates that the core network device has the conditions required to establish an interface connection, notification information that can be established is generated. In another example, when the status information indicates that the core network device does not have the conditions required to establish an interface connection (usually, the startup status of the process related to establishing an interface connection on the core network device is abnormal, but the connection status of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network is interoperable), notification information that cannot be established is generated.

上述602中，将所述通知信息发送给所述移动通信网络中的目标接入网设备，以由所述目标接入网设备在请求建立接口连接时参考。In the above 602, the notification information is sent to the target access network device in the mobile communication network, so that the target access network device can refer to it when requesting to establish an interface connection.

若通知信息为可建通知信息，则目标接入网设备在接收到通知信息后，可立即向核心网设备发送接口连接建立请求。If the notification information is a notification information that can be established, the target access network device may immediately send an interface connection establishment request to the core network device after receiving the notification information.

若通知信息为不可建通知信息，则目标接入设备在接收到通知信息后，可等待核心网设备发送可建通知信息之后，再向核心网设备发送接口建立请求。If the notification information is notification information of unestablishable connection, after receiving the notification information, the target access device may wait for the core network device to send notification information of establishable connection, and then send an interface establishment request to the core network device.

通常，核心网设备启动后到具备建立接口连接所需的条件需要经过一段时间，核心网设备在启动后且未具备建立接口连接所需的条件时，生成一不可建通知信息，并发送给目标接入网设备；在其具备建立接口连接所需的条件时，生成一可建通知信息，并发送给目标接入网设备。Usually, it takes some time for the core network device to meet the conditions required to establish an interface connection after it is started. When the core network device is started but does not meet the conditions required to establish an interface connection, it generates a notification message that it cannot be established and sends it to the target access network device. When it meets the conditions required to establish an interface connection, it generates a notification message that it can be established and sends it to the target access network device.

这样，接入网设备无需周期性地尝试发送接口建立请求，可减少网络资源开销；并且，还能够在核心网设备具备建立接口连接所需的条件时，即可与核心网设备建立接口连接，可缩短建立耗时，进而有效提高接口连接建立的效率。In this way, the access network device does not need to periodically attempt to send interface establishment requests, which can reduce network resource overhead; and it can also establish an interface connection with the core network device when the core network device has the conditions required to establish an interface connection, which can shorten the establishment time and effectively improve the efficiency of establishing the interface connection.

在一种可实现的方案中，上述602中“根据所述状态信息，生成通知信息”，具体可包括如下步骤：In an achievable solution, the step of “generating notification information according to the status information” in 602 may specifically include the following steps:

6021、根据所述状态信息，确定所述核心网设备是否具备建立接口连接的条件。6021. Determine whether the core network device is capable of establishing an interface connection based on the status information.

6022、确定出所述核心网设备具备建立接口连接的条件时，生成通知信息。6022. When it is determined that the core network device is capable of establishing an interface connection, notification information is generated.

所述核心网设备上的与建立接口连接相关的进程的运行状态正常且所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态为互通状态时，说明该核心网设备具备建立接口连接所需的条件。所述核心网设备上的与建立接口连接相关的进程的运行状态不正常或所述核心网设备与所述移动通信网络中的目标接入网设备之间的网际互连协议连接的连接状态不互通时，说明该核心网设备不具备建立接口连接所需的条件。When the running status of the process related to establishing the interface connection on the core network device is normal and the connection status of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network is in an intercommunication state, it indicates that the core network device has the conditions required to establish the interface connection. When the running status of the process related to establishing the interface connection on the core network device is abnormal or the connection status of the Internet Protocol connection between the core network device and the target access network device in the mobile communication network is not intercommunication, it indicates that the core network device does not have the conditions required to establish the interface connection.

在本实施例中，只有在确定出所述核心网设备具备建立接口连接的条件时，才会生成通知信息。目标接入设备在接收到通知信息后，可立即向核心网设备发送接口建立请求。In this embodiment, the notification information is generated only when it is determined that the core network device has the conditions for establishing an interface connection. After receiving the notification information, the target access device can immediately send an interface establishment request to the core network device.

需要补充说明的是，本申请实施例中，核心网设备的状态信息用于表明核心网设备是否满足建立接口连接的条件，也就是说，核心网设备的状态信息本质上是整个核心网的状态信息，整个核心网的状态信息满足建立接口连接的条件，其核心网设备的状态信息才能够满足建立接口连接的条件。It should be noted that, in the embodiment of the present application, the status information of the core network device is used to indicate whether the core network device meets the conditions for establishing an interface connection. That is to say, the status information of the core network device is essentially the status information of the entire core network. Only when the status information of the entire core network meets the conditions for establishing an interface connection can the status information of its core network device meet the conditions for establishing an interface connection.

图7示出了本申请又一实施例提供的通信方法的流程示意图。其中，所述方法适用于移动通信网络中的接入网设备，也即该方法的执行主体为接入网设备。如图7所示，所述方法，包括：FIG7 shows a flow chart of a communication method provided by another embodiment of the present application. The method is applicable to an access network device in a mobile communication network, that is, the execution subject of the method is an access network device. As shown in FIG7 , the method includes:

701、接收所述移动通信网络中的核心网设备发送来的通知信息。701. Receive notification information sent by a core network device in the mobile communication network.

其中，所述通知信息是所述核心网设备根据所述核心网设备的状态信息生成的。The notification information is generated by the core network device according to the status information of the core network device.

702、根据所述通知信息，确定是否向所述核心网设备发送接口连接建立请求。702. Determine whether to send an interface connection establishment request to the core network device according to the notification information.

在一实例中，上述702中，若通知信息包括所述核心网设备的状态信息，则可根据状态信息确定核心网设备是否具备建立接口连接的条件。若具备，可确定向所述核心网设备发送接口连接建立请求。若不具备，可确定不向所述核心网设备发送接口连接建立请求。In one example, in the above 702, if the notification information includes the status information of the core network device, it can be determined whether the core network device has the conditions for establishing an interface connection according to the status information. If so, it can be determined to send an interface connection establishment request to the core network device. If not, it can be determined not to send an interface connection establishment request to the core network device.

在另一实例中，上述702中，若通知信息为可建通知信息，则确定向所述核心网设备发送接口连接建立请求。若通知信息为不可建通知信息，可确定不向所述核心网设备发送接口连接建立请求。In another example, in the above 702, if the notification information is a notification information of establishment possible, it is determined to send an interface connection establishment request to the core network device. If the notification information is a notification information of non-establishment possible, it is determined not to send an interface connection establishment request to the core network device.

如图8所示，核心网设备启动后，进行自检，也即是获取核心网设备的状态信息，并根据核心网设备的状态信息确定所述核心网设备是否具备建立接口连接的条件。确定出所述核心网设备具备建立接口连接的条件时，生成S1(或NG)setup remind；将S1(或NG)setupremind发送给接入网设备(对应步骤801)。接入网设备接收到S1或NG setup remind后，向核心网设备发送S1(或NG)setup request(对应步骤802)。核心网设备接收到S1(或NG)setup request后，若同意接入，则向接入网设备返回S1(或NG)setup response(对应步骤803)；若不同意接入，则向接入网设备返回S1(或NG)setup failure。As shown in Figure 8, after the core network device is started, it performs a self-check, that is, obtains the status information of the core network device, and determines whether the core network device has the conditions to establish an interface connection based on the status information of the core network device. When it is determined that the core network device has the conditions to establish an interface connection, S1 (or NG) setup remind is generated; S1 (or NG) setup reminder is sent to the access network device (corresponding to step 801). After receiving S1 or NG setup remind, the access network device sends S1 (or NG) setup request to the core network device (corresponding to step 802). After receiving S1 (or NG) setup request, if the core network device agrees to access, it returns S1 (or NG) setup response to the access network device (corresponding to step 803); if it does not agree to access, it returns S1 (or NG) setup failure to the access network device.

现有的技术方案中，没有S1(或NG)setup remind流程，基站不知道当前核心网的状态，根据定时器SCTP(Stream Control Transmission Protocol，流控制传输协议)WaitTimer周期性盲发送S1(或NG)setup request给核心网。即使核心网状态准备完成，基站也需要定时器轮询到才能发送S1(或NG)setup request给核心网，无法及时建立接口连接。In the existing technical solution, there is no S1 (or NG) setup remind process. The base station does not know the current state of the core network. It periodically and blindly sends the S1 (or NG) setup request to the core network according to the timer SCTP (Stream Control Transmission Protocol) WaitTimer. Even if the core network state is ready, the base station needs to poll the timer to send the S1 (or NG) setup request to the core network, and the interface connection cannot be established in time.

本申请实施例还提供一种通信系统，其中，包括：核心网设备以及接入网设备。An embodiment of the present application also provides a communication system, which includes: a core network device and an access network device.

所述核心网设备，用于获取所述核心网设备的状态信息；根据所述状态信息，生成通知信息；将所述通知信息发送给所述移动通信网络中的目标接入网设备，以由所述目标接入网设备在请求建立接口连接时参考；The core network device is used to obtain status information of the core network device; generate notification information according to the status information; and send the notification information to a target access network device in the mobile communication network for reference by the target access network device when requesting to establish an interface connection;

这里需要说明的是：本申请实施例提供的核心网设备以及接入网设备的具体实现和交互过程可参见上述实施例中的相应内容，此处不再赘述。It should be noted here that the specific implementation and interaction process of the core network equipment and access network equipment provided in the embodiments of the present application can be found in the corresponding contents in the above embodiments and will not be repeated here.

下面将结合无人驾驶车为例，对本申请实施例提供的技术方案进行举例详细介绍：The following will take the unmanned vehicle as an example to introduce the technical solution provided in the embodiment of the present application in detail:

假设用户乘坐无人驾驶车上班，该无人驾驶车在启动后成功驻留在A小区(A小区属于跟踪区TAC-1)，A小区的基站与5G核心网中的AFM-1设备之间建立有NG接口连接。无人驾驶车驻网成功后，AFM-1设备将事先收集到的跟踪区TAC-1对应的频段信息通过A小区基站发送给无人驾驶车，无人驾驶车将跟踪区TAC-1对应的频段信息存储在本地；无人驾驶车还会将本次驻网成功的历史频段存储在本地。在无人驾驶车行驶过程中，5G核心网出现故障下线，导致A小区的基站与5G核心网中的AFM-1设备之间的NG接口连接断开，进而导致无人驾驶车掉网。5G核心网故障解除后自动重启，AFM-1设备在重启后，实时获取其状态信息，并根据状态信息确定当前是否满足建立接口连接的条件，在确定出当前满足建立接口连接的条件时，向A小区的基站发送NG setup remind，A小区的基站接收到NG setup remind后，立即向AFM-1设备发送NG setup request，AFM-1设备接收到NG setup request后，确定能够接入，于是向A小区的基站发送NG setup response，A小区的基站接收到NG setupresponse后，即表明NG接口连接建立成功。A小区的基站与AFM-1设备建立好NG接口连接之后，A小区的基站即可提供正常通讯服务。可见，核心网准确完成后，接入网设备可立即与其建立接口连接，无需等待定时器轮询到来，提高了建立接口连接的效率。Assume that a user takes an unmanned vehicle to work. After starting, the unmanned vehicle successfully resides in cell A (cell A belongs to tracking area TAC-1). An NG interface connection is established between the base station of cell A and the AFM-1 device in the 5G core network. After the unmanned vehicle successfully resides in the network, the AFM-1 device sends the previously collected frequency band information corresponding to the tracking area TAC-1 to the unmanned vehicle through the base station of cell A. The unmanned vehicle stores the frequency band information corresponding to the tracking area TAC-1 locally; the unmanned vehicle also stores the historical frequency bands of this successful network residency locally. During the driving of the unmanned vehicle, the 5G core network fails and goes offline, causing the NG interface connection between the base station of cell A and the AFM-1 device in the 5G core network to be disconnected, which in turn causes the unmanned vehicle to lose the network. The 5G core network automatically restarts after the fault is resolved. After restarting, the AFM-1 device obtains its status information in real time, and determines whether the conditions for establishing an interface connection are currently met based on the status information. When it is determined that the conditions for establishing an interface connection are currently met, it sends an NG setup remind to the base station in cell A. After receiving the NG setup remind, the base station in cell A immediately sends an NG setup request to the AFM-1 device. After receiving the NG setup request, the AFM-1 device determines that it can be accessed, so it sends an NG setup response to the base station in cell A. After the base station in cell A receives the NG setup response, it indicates that the NG interface connection is successfully established. After the base station in cell A establishes an NG interface connection with the AFM-1 device, the base station in cell A can provide normal communication services. It can be seen that after the core network is accurately completed, the access network device can immediately establish an interface connection with it without waiting for the timer polling to arrive, which improves the efficiency of establishing the interface connection.

同时，由于无人驾驶车掉网，无人驾驶车需要立即重新驻网。无人驾驶车可优先根据上次驻网成功的历史频段进行驻网，若驻网不成功，则根据跟踪区TAC-1对应的频段信息进行驻网；若还驻网不成功，则根据无人驾驶车所支持的全频段进行驻网。At the same time, since the driverless car has lost the network, the driverless car needs to re-establish network connection immediately. The driverless car can preferentially establish network connection based on the historical frequency band where network connection was successful last time. If network connection is unsuccessful, it can establish network connection based on the frequency band information corresponding to the tracking area TAC-1. If network connection is still unsuccessful, it can establish network connection based on the full frequency band supported by the driverless car.

下面将结合手机为例，对本申请实施例提供的技术方案进行举例详细介绍：The following will take a mobile phone as an example to introduce the technical solution provided in the embodiment of the present application in detail:

用户白天在景区旅游的过程中，手机因没电关机了。等到晚上，用户回到酒店后对手机进行充电，充电后并开启了手机。这时候，手机先根据本地存储的上次驻网成功的历史频段进行驻网，由于景区和酒店所在的小区不同，基于历史频段驻网失败。于是，手机根据本地存储的上次驻网成功后核心网设备通过基站发送来的其上次所在的跟踪区对应的频段信息进行驻网，由于景区和酒店在同一跟踪区，基于上次所在的跟踪区对应的频段信息驻网成功。这样一来，避免了全频段扫描，缩短了驻网时间。During the daytime, the user's mobile phone was turned off due to lack of power while touring the scenic spot. At night, the user returned to the hotel to charge the mobile phone, and then turned it on. At this time, the mobile phone first settled on the network based on the historical frequency band of the last successful settlement stored locally. Since the scenic spot and the hotel are located in different communities, the settlement based on the historical frequency band failed. Therefore, the mobile phone settled on the network based on the frequency band information corresponding to the tracking area where it was last located, which was sent by the core network equipment through the base station after the last successful settlement. Since the scenic spot and the hotel are in the same tracking area, the settlement is successful based on the frequency band information corresponding to the last tracking area. In this way, full-band scanning is avoided and the settlement time is shortened.
