步骤101：针对不同APN分别建立各APN对应的移动性管理配置；Step 101: For different APNs, respectively establish a mobility management configuration corresponding to each APN;
这里，在核心网中预先对不同的APN建立与各个APN对应移动性管理配置；具体的，APN决定了UE访问网络的权限和方式，移动性管理配置是访问网络所需要的参数配置，预先确定各APN访问网络的权限和方式，建立与各APN访问网络权限和方式对应的移动性管理配置；如此，可针对特殊的APN建立该APN对应的移动性管理配置。Here, the mobility management configuration corresponding to each APN is established in advance for different APNs in the core network; specifically, the APN determines the authority and method of the UE to access the network, and the mobility management configuration is the parameter configuration required for accessing the network, which is determined in advance.

表1Table 1
表2Table 2
步骤102：接收UE附着请求，获取UE上报的APN；Step 102: Receive the UE attach request, and obtain the APN reported by the UE;
这里，当接收到UE的附着请求时，获取UE上报的APN；以图2所示演进的分组系统(EPS，Evolved Packet System)附着信令流程为例，本实施例在步骤201中，当UE连接到网络时，会发送附着请求给MME并上报APN，此时，获取UE上报的APN。Here, when an attach request from the UE is received, the APN reported by the UE is obtained; taking the Evolved Packet System (EPS, Evolved Packet System) attach signaling process shown in FIG. 2 as an example, in this embodiment, in
步骤103：根据预先设置的APN移动性管理策略对UE进行移动性管理；Step 103: Perform mobility management on the UE according to a preset APN mobility management policy;
这里，将步骤102中获取的APN与步骤101中预设的移动性管理配置中的APN进行比较；根据比较结果依据预先设置的APN移动性管理策略进行移动性管理；Here, the APN obtained in
所述APN移动性管理策略可以根据由APN区分出来的不同类型UE，例如：普通UE、行业UE、特殊UE等来进行访问网络的权限和方式的控制；所述APN移动性管理策略可以有：限制特定APN的UE访问特定网站、设定特定APN的UE的附着流程时间等；这些控制具体涉及到的是针对一些定时器的设置；如图3所示，所述对UE进行移动性管理包括：The APN mobility management policy may control the authority and mode of accessing the network according to different types of UEs distinguished by APNs, such as ordinary UEs, industrial UEs, and special UEs, etc. The APN mobility management policies may include: Restricting UEs of a specific APN to access a specific website, setting the attachment process time of the UE of a specific APN, etc.; these controls are specifically related to the settings of some timers; as shown in Figure 3, the mobility management for the UE includes: :
步骤1031：判断移动性管理配置中是否存在与所述UE的APN相对应的业务使用限制，如果所述移动性管理配置中存在与所述UE的APN相对应的业务使用限制，则执行步骤1032；否则，执行步骤1033；Step 1031: Determine whether there is a service usage restriction corresponding to the APN of the UE in the mobility management configuration, and if there is a service usage restriction corresponding to the APN of the UE in the mobility management configuration, perform
步骤1032：拒绝UE附着，结束本次处理流程；Step 1032: reject the UE attachment, and end this processing flow;
这里，如果业务使用限制类型是特定用户接入时，则允许所述UE附着，而拒绝其他UE附着；在拒绝UE附着时，在拒绝消息里携带原因值，以便网管统计时识别；Here, if the service usage restriction type is when a specific user accesses, the UE is allowed to attach, while other UEs are refused to attach; when the UE is refused to attach, the reason value is carried in the rejection message, so that the network management can identify it during statistics;
步骤1033：判断移动性管理配置中是否存在与所述UE的APN相对应的移动性管理配置，如果所述移动性管理配置中存在与所述UE的APN相对应的移动性管理配置，则执行步骤1034；否则，执行步骤1035；Step 1033: Determine whether there is a mobility management configuration corresponding to the APN of the UE in the mobility management configuration, and if there is a mobility management configuration corresponding to the APN of the UE in the mobility management configuration, execute
步骤1034：采用移动性管理配置中的设置，结束本次处理流程；这里，移动性管理配置中的设置可以是定时器设置，所述定时器包括UE的定时器、MME或SGSN的定时器等；Step 1034: Use the settings in the mobility management configuration to end this processing flow; here, the settings in the mobility management configuration may be timer settings, and the timers include the timer of the UE, the timer of the MME or the SGSN, etc. ;
具体的，核心网的移动性管理配置已经配置了与所述UE的APN相对应的定时器设置，因此，附着流程中涉及到使用的各定时器配置不再使用全局定时器设置，而是使用移动性管理配置中与所述UE的APN相对应的各定时器设置，例如：用户可达定时器、T3412、T3413等定时器，从而让核心网尽快更新所述UE的状态，且不影响其他UE；Specifically, the mobility management configuration of the core network has been configured with timer settings corresponding to the APN of the UE. Therefore, each timer configuration involved in the attach process no longer uses the global timer settings, but uses Each timer setting corresponding to the APN of the UE in the mobility management configuration, such as: user reachable timer, T3412, T3413 and other timers, so that the core network can update the state of the UE as soon as possible without affecting other UE;
这里，全局定时器设置为针对全局所有APN所设定的通用定时器设置；移动性管理配置的定时器设置可以是针对一些特殊APN设定的与该APN对应的有针对性的特殊定时器设置；UE的定时器为UE实际运行的定时器，UE的定时器根据移动性管理配置的定时器设置或全局定时器设置运行；MME/SGSN的定时器为MME/SGSN实际运行的定时器，MME/SGSN的定时器根据移动性管理配置的定时器设置或全局定时器设置运行；Here, the global timer setting is a general timer setting set for all global APNs; the timer setting of the mobility management configuration may be a targeted special timer setting corresponding to the APN set for some special APNs ; The timer of the UE is the actual running timer of the UE, and the timer of the UE runs according to the timer setting of the mobility management configuration or the global timer setting; the timer of the MME/SGSN is the actual running timer of the MME/SGSN. The timer of the /SGSN runs according to the timer setting of the mobility management configuration or the global timer setting;
步骤1035：采用核心网预设的全局设置，结束本次处理流程；这里，全局设置可以是全局定时器设置；所述定时器包括UE的定时器、MME或SGSN的定时器等；如此，可以采用全局定时器设置启动定时器；Step 1035: adopt the global setting preset by the core network, and end this processing flow; here, the global setting may be a global timer setting; the timer includes the timer of the UE, the timer of the MME or the SGSN, etc.; Use the global timer setting to start the timer;
具体的，预设的移动性管理配置的定时器设置优先级高于全局定时器设置，例如：预设的移动性管理配置的定时器设置中的位置更新定时器值优先级高于全局位置更新定时器数值；预设的移动性管理配置的定时器设置中的漫游接入限制高于全局配置中的漫游接入限制。Specifically, the timer setting priority of the preset mobility management configuration is higher than the global timer setting. For example, the location update timer value in the timer setting of the preset mobility management configuration has a higher priority than the global location update. Timer value; the roaming access restriction in the timer setting of the preset mobility management configuration is higher than the roaming access restriction in the global configuration.
本发明实施例提供的移动性管理的方法适用于LTE网络、GPRS网络。The mobility management method provided by the embodiment of the present invention is applicable to LTE network and GPRS network.
下面结合具体示例1对本发明中作进一步详细的描述，本实施例中，采用本发明的移动性管理方法可以提高寻呼成功率。The present invention will be described in further detail below with reference to specific example 1. In this embodiment, the mobility management method of the present invention can improve the paging success rate.
针对4G用户的接入，目前出现了LTE-Fi(LTE and WiFi)接入形式，如：在公交车上进行4G WiFi，通过WiFi为乘客提供4G数据接入功能；但由于MME在设置中只能对用户可达定时器、T3412、T3413等定时器进行全局设定，因此，无法针对公交专用行业的APN进行单独设置，而公交车上的4G WiFi设备往往在公交车完成营运后，会随着车辆熄火而突然供电中断，导致设备无法及时和核心网进行交互完成承载删除、去附着等流程，从而，导致附着成功率等指标异常，严重影响维护、故障判断等工作。For the access of 4G users, LTE-Fi (LTE and WiFi) access forms have emerged, such as: 4G WiFi on the bus, providing 4G data access for passengers through WiFi; The user-reachable timer, T3412, T3413 and other timers can be set globally. Therefore, it is impossible to individually set the APN for the bus-only industry, and the 4G WiFi devices on the bus often follow the bus after the bus is completed. When the vehicle is turned off and the power supply is suddenly interrupted, the device cannot interact with the core network in a timely manner to complete processes such as bearer deletion and de-attachment. As a result, indicators such as the attachment success rate are abnormal, which seriously affects maintenance and fault judgment.
采用本发明实施例的方法进行区分APN的设置后，使用该APN附着时，MME首先检查该APN是否在限制接入列表中，检测不在限制接入列表后，进行正常附着流程，由于在核心网已经配置了针对该APN单独设置的各种定时器，因此，附着流程中涉及到使用的各定时器配置不再使用全局定时器设置，而是使用针对公交的专用APN进行各定时器设置，例如：减小用户可达定时器、T3412、T3413等定时器，从而让核心网尽快更新终端状态，降低寻呼频率，提升寻呼成功率等指标，且不影响其他用户。After using the method of the embodiment of the present invention to distinguish the setting of the APN, when using the APN to attach, the MME first checks whether the APN is in the restricted access list, and after detecting that the APN is not in the restricted access list, performs the normal attachment process. Various timers individually set for this APN have been configured. Therefore, each timer configuration involved in the attachment process no longer uses the global timer setting, but uses the dedicated APN for the bus to set each timer. For example : Reduce the user reachable timer, T3412, T3413 and other timers, so that the core network can update the terminal status as soon as possible, reduce the paging frequency, improve the paging success rate and other indicators, without affecting other users.
需要特别说明的是，由于现网存在多公用数据网(PDN，Public Data Network)连接，且用户同时使用不止一个APN进行业务，因此，针对APN修改的移动性管理配置中定时器设置的优先级高于全局定时器设置优先级。It should be noted that, since there are multiple public data network (PDN, Public Data Network) connections on the existing network, and users use more than one APN for services at the same time, the priority of the timer setting in the mobility management configuration modified for APN Higher priority than the global timer setting.
下面结合具体示例2对本发明中作更进一步详细的描述，本实施例中，采用本发明的移动性管理方法可以限制用户接入。The present invention will be described in further detail below with reference to specific example 2. In this embodiment, user access can be restricted by using the mobility management method of the present invention.
以往要临时限制一个APN的用户使用数据业务，通常的做法是：要么业务操作支撑系统(BOSS，Business&Operation Support System)或用户归属地服务器(HSS，HomeSubscriber Server)通过修改签约数据限制用户使用，要么在网关GPRS支持节点(GGSN，Gateway GPRS Support Node)/系统架构演进网关(SAEGW，System ArchitectureEvolution Gateway)上锁定该APN，并手动剔除已使用该APN接入的用户。In the past, it was necessary to temporarily restrict the use of data services by users of an APN. The usual practice was: either the business operation support system (BOSS, Business&Operation Support System) or the user's home server (HSS, HomeSubscriber Server) restricted users by modifying the subscription data, or The APN is locked on the Gateway GPRS Support Node (GGSN, Gateway GPRS Support Node)/System Architecture Evolution Gateway (SAEGW, System Architecture Evolution Gateway), and users who have used the APN for access are manually excluded.
但修改签约数据的办法风险性很大，且涉及批量用户的数据操作，因此，这种方法通常不轻易使用；闭锁APN是目前通常使用的方法，但这样做的缺点是：用户进行附着前期和核心网设备的信令交互正常进行，直到如图2步骤202所示：PGW/GGSN回复失败后(creatsession rep./creat pdp rsp.)，流程才结束；这样，既造成了信令的交互浪费，又极大的影响附着成功率等指标。However, the method of modifying the contract data is very risky and involves data operations of batch users. Therefore, this method is usually not easy to use; blocking APN is a method commonly used at present, but the disadvantage of this method is that users perform pre-attachment and The signaling interaction of the core network equipment is carried out normally, and the process ends when the PGW/GGSN reply fails (creatsession rep./creat pdp rsp.), as shown in
而通过本发明的移动性管理方法，MME增加了区分APN的移动性管理功能后，如图2步骤201所示：MME在用户发起附着请求后，可以立即拒绝用户附着，并可选的回复错误原因(可以通过命令配置确定MME回复UE的错误原因)，从而既节省了余下的信令交互，降低了信令负荷；同时，也可以通过配置修改MME回复的错误原因值，避免造成附着成功率等业务指标下降的问题。With the mobility management method of the present invention, after the MME adds the mobility management function of distinguishing APNs, as shown in
特别需要说明的是：在网管统计中，网管设备会根据用户失败原因进行归类统计附着成功率等业务指标，部分原因归于用户原因，部分原因归于网络原因等，因此，在设置因此种方法而拒绝用户的错误时，只要选择正确的错误原因值，网管统计时是可以将此类型的错误剔除，从而达到不影响附着成功率等业务指标的目的。It should be noted that: in the network management statistics, the network management device will classify and count business indicators such as the attachment success rate according to the reasons for user failures. Some of the reasons are due to user reasons, and some of the reasons are due to network reasons. When rejecting user errors, as long as the correct error cause value is selected, the network management can eliminate this type of errors during statistics, so as to achieve the purpose of not affecting business indicators such as the success rate of attachment.
