Description

延迟判定方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及延迟判定方法和装置，电子设备和计算机可读存储介质。
背景技术
在移动通信技术中，终端为了获得网络提供的业务，需要先向网络进行注册。
终端在向网络注册后，可以获取网络配置的周期性注册更新定时器(Periodic registration update timer)，以根据该周期性注册更新定时器，周期性地向网络进行注册区域更新。
对于网络而言，可以为已注册的终端维护移动可达定时器(Mobile reachable timer)和隐式去注册定时器(Implicit detach timer)，根据该定时器、以及接收终端发送的周期性注册区域更新消息，来确定终端的状态。
然而，终端可能处于不便于进行周期性注册区域更新的情况，例如多卡终端中的其中一张SIM卡正在进行通信时，另一张SIM卡可能不便于进行周期性注册区域更新。在这种情况下，如何避免终端因为周期性注册区域更新不及时而被网络错误地判定状态，例如被错误地标识为不可达或被错误地去注册，成了亟待解决的问题。
发明内容
有鉴于此，本公开的实施例提出了一种延迟判定方法，以解决相关技术中的技术问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种延迟判定方法的示意流程图。本实施例所示的延迟判定方法可以适用于核心网，所述核心网包括但不限于4G核心网、5G核心网、6G核心网。所述核心网可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。在一个实施例中，所述终端可以是后续任一实施例所述延迟判定方法所适用的终端。
如图1所示，所述延迟判定方法可以包括以下步骤：
在步骤S101中，响应于接收到终端发送的繁忙指示，延迟与所述终端的可达状态相关联的判定过程。
在一个实施例中，终端在向核心网注册后，可以从核心网获取一个定时时长，用于设置周期性注册更新定时器。终端可以根据该周期性注册更新定时器，周期性地发起注册区域更新，以向核心网表明终端仍处于网络覆盖范围内。例如，终端可以在该周期性注册更新定时器超时后向核心网发起注册区域更新。
在核心网中，可以为已注册的终端维护移动可达定时器和隐式去注册定时器， 且该移动可达定时器的时长略大于为终端配置的周期性注册更新定时器。
当终端变为空闲态时，核心网启动移动可达定时器，若在移动可达定时器超时前，接收到终端注册区域更新的消息，则停止该移动可达定时器；若在移动可达定时器超时后，未接收到终端注册区域更新的消息，则清除该终端的寻呼处理指示位PPF(Paging Proceed Flag)，标识终端不可达，从而不会触发对UE的寻呼，一旦确定移动可达定时器超时，核心网将启动隐式去注册定时器；若在隐式去注册定时器超时前，接收到终端注册区域更新的消息，则停止该隐式去注册定时器，并将PPF置位(即标识终端可达)；若在隐式去注册定时器超时后，未接收到终端注册区域更新的消息，则发起对终端的隐式去注册。需要说明的是，核心网对终端发起隐式去注册后，后续终端需要重新向核心网进行注册，需要耗费较多的通信资源等。
一般情况下，当终端不在网络的覆盖范围内，终端才会长期不进行注册区域更新，进而导致核心网中的移动可达定时器和隐式去注册定时器超时，然而，当终端的周期性注册更新定时器超时时，终端可能处于不便于进行周期性注册区域更新的情况，虽然终端仍在网络的覆盖范围内，无需核心网对终端标记为不可达或去注册，但是由于终端未能及时进行注册区域更新，从而导致核心网对终端的可达状态进行了错误的判定。
例如，设置有第一SIM卡和第二SIM卡的终端，当第一SIM卡正在进行通信时，第二SIM卡的周期性注册更新定时器超时，若第二SIM卡进行注册区域更新则会影响第一SIM正在进行的通信业务；若第二SIM卡不及时注册区域更新，则可能会导致被核心网标记为不可达，甚至被去注册，在这种情况下，第二SIM卡仍在核心网对应网络的覆盖范围内，但是由于被去注册，在第二SIM卡需要接入核心网时，还需要重新发起注册流程，浪费了通信资源。
针对上述技术问题，本公开提出一种新的延迟判定方法，核心网可以延迟与所述终端的可达状态相关联的判定过程。
在一个实施例中，核心网可以接收终端发送的繁忙指示，在核心网延迟与所述终端的可达状态相关联的判定过程。
在一个实施例中，终端的可达状态指示该终端针对核心网中的AMF(接入和移动管理功能)来说是否可达，因此可达状态包括可达或不可达。在一个实施例中，与终端可达状态相关联的判定过程包括两种，其一为判定移动可达定时器是否超时， 当移动可达定时器未超时，可以确定终端可达，当移动可达定时器超时，可以标识终端不可达；其二为判定隐式去注册定时器是否超时，当隐式去注册定时器超时，则对终端去注册。
在一个实施例中，发送该繁忙指示的终端可以是多卡终端。举例来说，对于至少设置有第一SIM卡和第二SIM卡的终端，响应于所述第二SIM卡注册区域更新的操作与所述第一SIM卡进行的通信操作冲突，向所述第二SIM卡对应的核心网发送繁忙指示。基于此，核心网在接收到第二SIM卡发送的繁忙指示后，可以延迟与所述第二SIM卡的可达状态相关联的判定过程。
需要说明的是，对于核心网而言，每张SIM卡即对应一个终端，而并不会区分是否为多卡终端。
至此，完成了图1所示的实施例。根据图1所示实施例，终端可以通过繁忙指示来指示核心网延迟与所述终端的可达状态相关联的判定过程，避免终端的状态被错误地判定，从而避免后续更新状态时导致的通信资源浪费情况。例如可以延迟对终端进行去注册，避免终端仍处于核心网覆盖范围内却被错误地去注册，避免了后续终端需要重新注册导致的通信资源浪费等情况。
图2是根据本公开的实施例示出的另一种延迟判定方法的示意流程图。
如图2所示，所述延迟与所述终端的可达状态相关联的判定过程，包括：
在步骤S201中，暂停所述核心网中与所述终端对应的移动可达定时器或隐式去注册定时器。
在一个实施例中，终端发送的繁忙指示用于请求核心网暂停移动可达定时器，或隐式去注册定时器。
核心网在接收到终端发送的繁忙指示后，首先可以确定当前正在计时的定时器，例如可以是移动可达定时器，或者也可以是隐式去注册定时器，然后暂停该定时器。
在一个实施例中，核心网可以根据移动可达定时器是否超时，来具体确定暂停哪一个定时器。
响应于所述终端对应的移动可达定时器未超时，暂停所述移动可达定时器。
响应于所述终端对应的移动可达定时器超时，暂停所述隐式去注册定时器。
在一个实施例中，所述方法还包括：响应于在暂停所述移动可达定时器或隐式去注册定时器后接收到所述终端的注册区域更新请求，重新启动所述移动可达定时器。
核心网在根据上述实施例暂停定时器后，处于等待终端发起注册区域更新的状态，后续，若核心网接收到终端的注册区域更新请求，则停止该被暂停的定时器。可以理解的是，核心网接收到终端的注册区域更新请求，则可以确定终端可达，此时，核心网可以重新启动移动可达定时器。
需要说明的是，“重新启动移动可达定时器”可以为：根据移动可达定时器被配置的定时时长，重新从头开始计时。以移动可达定时器的定时时长为10ms为例，本实施例中，假设移动可达定时器计时到6ms时被暂停，则核心网在接收到终端发送的注册区域更新请求后，将该移动可达定时器重新从0ms开始计时。
在一个实施例中，还包括一种替换方案，可以将上述重新启动移动可达定时器，替换为继续启动被暂停的定时器，例如被暂停的定时器为移动可达定时器，则继续启动移动可达定时器；或者被暂停的定时器为隐式去注册定时器，则继续启动隐式去注册定时器。举例来说，若移动可达定时器计时到6ms时被暂停，则核心网在接收到终端发送的注册区域更新请求后，将该移动可达定时器恢复计时(即从6ms开始继续计时，例如，假设该定时器被设置为总计时时长为10ms，那么该移动可达定时器还将计时4ms)，直至剩余的计时时长结束；或者，若隐式去注册定时器计时到6ms时被暂停，则核心网在接收到终端发送的注册区域更新请求后，将该隐式去注册定时器恢复计时(即从6ms之后继续计时，同上所述)。
至此，完成了图2所示的实施例。根据图2所示的实施例，核心网在接收到终端的繁忙指示后，会暂停当前正在计时的定时器，并等待终端发起注册区域更新。由此，可以避免终端仍处于核心网覆盖范围内，却因不便进行注册区域更新而被错误地标记为不可达、甚至被错误地去注册，进而可以避免通信资源浪费等情况。
图3是根据本公开的实施例示出的另一种延迟判定方法的示意流程图。
如图3所示，所述繁忙指示中包含繁忙时长。所述延迟与所述终端的可达状态相关联的判定过程，包括：
在步骤S301中，将所述与所述终端的可达状态相关联的判定过程暂停所述繁忙时长。
核心网在接收到终端发送的繁忙指示后，首先可以确定当前正在计时的定时 器，例如可以是移动可达定时器，或者也可以是隐式去注册定时器，然后暂停该定时器。
在一个实施例中，确定当前正在为运行的定时器方法可以与图2所示实施例的中方法类似，响应于所述终端对应的移动可达定时器未超时，则确定当前正在计时的定时器为移动可达定时器；响应于所述终端对应的移动可达定时器超时，则确定当前正在计时的定时器为隐式去注册定时器。
在一个实施例中，核心网可以根据繁忙指示所携带的繁忙时长，对定时器暂停该繁忙时长。
响应于所述终端对应的移动可达定时器未超时，将所述移动可达定时器暂停所述繁忙时长；
响应于所述终端对应的移动可达定时器超时，将所述隐式去注册定时器暂停所述繁忙时长。
需要说明的是，核心网对定时器暂停所述繁忙时长，可以为：核心网将定时器暂停，并在所述繁忙时长后，继续启动该定时器。“继续启动该定时器”可以为：先暂停定时器的计时，然后在经过所述繁忙时长后，恢复定时器的计时(即定时器沿着暂停时的计时继续计时)。举例来说，以一个定时器的定时时长为10ms为例，假设定时器计时到6ms时被暂停，则经过繁忙时长后(例如经过时长为20ms的时间后)，将该定时器从6ms开始继续计时，直至剩余的计时时长结束。
核心网将移动可达定时器暂停所述繁忙时长，可以为：核心网先暂停该移动可达定时器，在所述繁忙时长后，继续启动该移动可达定时器；后续，若移动可达定时器超时，则仍标识终端不可达，并启动隐式去注册定时器，无需再进行暂停。核心网将隐式去注册定时器暂停所述繁忙时长，可以为：核心网先暂停该隐式去注册定时器，在所述繁忙时长后，继续启动该隐式去注册定时器；后续，若隐式去注册定时器，则对终端去注册。
需要说明的是，在一个实施例中，繁忙指示中不包含繁忙时长时，核心网也可以对终端的可达状态相关联的判定过程暂停一个指定时长，例如该指定时长可以为预先设定。举例来说，响应于所述终端对应的移动可达定时器未超时，将所述移动可达定时器暂停所述预设时长；响应于所述终端对应的移动可达定时器超时，如果所述隐式去注册定时器未超时，则将所述隐式去注册定时器暂停所述预设时长。
至此，完成了图3所示的实施例。根据图3所示的实施例，核心网在接收到终端的繁忙指示后，可以将当前正在计时的定时器暂停所述繁忙时长，以延迟将终端判定为不可达或去注册。一方面，可以避免终端因不便进行注册区域更新而被错误地去进行状态判定，例如被错误地去注册，另一方面，可以及时恢复定时器，避免定时器一直处于暂停状态，可以提高资源利用率。
在一个实施例中，核心网可以通过设置一个新的繁忙定时器来实现对上述移动可达定时器或隐式去注册定时器的暂停。下面结合图4和图5来进行说明。
图4是根据本公开的实施例示出的另一种延迟判定方法的示意流程图。
如图4所示，所述将所述核心网中与所述终端对应的移动可达定时器或隐式去注册定时器暂停所述繁忙时长包括：
在步骤S401中，暂停所述移动可达定时器或隐式去注册定时器。
在步骤S402中，启动定时时长与所述繁忙时长相同的繁忙定时器。
在步骤S403中，响应于所述繁忙定时器超时，继续启动所述移动可达定时器或隐式去注册定时器。
核心网在接收到繁忙指示后，首先可以根据移动可达定时器是否超时来确定当前正在计时的定时器，例如可以是移动可达定时器，或者也可以是隐式去注册定时器；然后，核心网可以暂停该定时器，并同时启动定时时长与繁忙指示所指示的繁忙时长一致的定时器；接着，在该繁忙定时器超时后，继续启动之前被暂停的定时器。
如图5所示，图中填充色为黑色的部分标识移动可达定时器；图中填充色为白色的部分标识繁忙定时器；图中填充图案为竖条纹部分标识隐式去注册定时器。
核心网在接收到终端发送的繁忙指示后，可以确定当前正在计时的定时器。以确定当前正在计时的定时器为移动可达定时器为例。首先可以暂停该移动可达定时器，即移动可达定时器暂停计时，并同时启动繁忙定时器，使繁忙定时器开始计时；若在该繁忙定时器超时后仍未收到终端发送的注册区域更新消息，则继续启动移动可达定时器，即移动可达定时器沿被暂停的计时继续计时；若在该移动可达定时器超时后仍未收到终端发送的注册区域更新消息，则标识终端不可达，并启动隐式去注册定时器，使隐式去注册定时器开始计时。后续，隐式去注册定时器不再进行暂停，若该隐式去注册定时器超时，则对终端去注册。
需要说明的是，图5只是以确定当前正在计时的定时器为移动可达定时器为例。在一个实施例中，核心网在接收到终端发送的繁忙指示后，若确定当前移动可达定时器已超时，则可以确定当前正在计时的定时器为隐式去注册定时器。此时，可以暂停隐式去注册定时器，并同时启动繁忙定时器，在该繁忙定时器超时后，继续启动隐式去注册定时器，即隐式去注册定时器沿被暂停的计时继续计时。
在一个实施例中，在上述任一定时器计时过程中，若核心网接收到终端发送的注册区域更新消息，则可以停止该定时器，或者还可以执行相应的操作。举例来说，若繁忙定时器在移动可达定时器暂停期间启动，在繁忙定时器或移动可达定时器计时期间，接收到终端发送的注册区域更新消息，则可以停止繁忙定时器或移动可达定时器；若繁忙定时器在隐式去注册定时器暂停期间启动，在繁忙定时器或隐式去注册定时器计时期间，接收到终端发送的注册区域更新消息，则可以停止繁忙定时器或移动可达定时器，并将终端对应的PPF置位。
图6是根据本公开的实施例示出的一种延迟判定方法的示意流程图。本实施例所示的延迟判定方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与核心网通信，所述核心网包括但不限于4G核心网、5G核心网、6G核心网。在一个实施例中，所述核心网可以是上述任一实施例所述的延迟判定方法所适用的核心网。其中，终端可以是多卡终端，至少设置有第一SIM卡和第二SIM卡。
如图6所示，所述延迟判定方法可以包括以下步骤：
在步骤S601中，响应于所述第二SIM卡注册区域更新的操作与所述第一SIM卡进行的通信操作冲突，向所述第二SIM卡对应的核心网发送繁忙指示。
其中，所述繁忙指示用于请求所述核心网延迟与所述终端的可达状态相关联的判定过程。
在一个实施例中，第一SIM卡正在进行通信时，第二SIM卡的周期性注册更新定时器超时，则第二SIM卡不便于向对应的核心网发起注册区域更新，例如若发起注册区域更新，则可能会影响第一SIM卡的通信业务。由此，终端可以通过第二SIM卡向第二SIM卡对应的核心网发送繁忙指示。
核心网在接收到该繁忙指示后，可以延迟与所述终端的可达状态相关联的判定过程。
在一个实施例中，终端发送的所述繁忙指示用于请求所述核心网暂停移动可达定时器，或隐式去注册定时器。
核心网在接收到该繁忙指示后，首先可以确定当前正在计时的定时器，例如可以是移动可达定时器，或者也可以是隐式去注册定时器，然后暂停该定时器。
举例来说，可以通过根据移动可达定时器是否超时，来具体确定暂停哪一个定时器。响应于所述终端对应的移动可达定时器未超时，暂停所述移动可达定时器；响应于所述终端对应的移动可达定时器超时，如果所述隐式去注册定时器未超时，暂停所述隐式去注册定时器。
在一个实施例中，终端向核心网发送的繁忙指示中包含繁忙时长，所述繁忙指示用于请求所述核心网将所述与所述第二SIM卡的可达状态相关联的判定过程暂停所述繁忙时长。
在一个实施例中，所述繁忙指示用于请求所述核心网将移动可达定时器，或隐式去注册定时器暂停所述繁忙时长。
核心网在接收到繁忙指示后，若确定该繁忙指示中包含繁忙时长，则可以对终端可达状态相关联的判定过程暂停所述繁忙时长。
举例来说，响应于所述终端对应的移动可达定时器未超时，将所述移动可达定时器暂停所述繁忙时长；响应于所述终端对应的移动可达定时器超时，将所述隐式去注册定时器暂停所述繁忙时长。

下面说明一个延迟判定方法的具体实施例。可以适用于终端，在所述终端中至 少设置有第一SIM卡和第二SIM卡，包括以下步骤：
响应于所述第二SIM卡注册区域更新的操作与所述第一SIM卡进行的通信操作冲突，向所述第二SIM卡对应的核心网发送繁忙指示；其中，所述繁忙指示用于请求所述核心网延迟与所述终端的可达状态相关联的判定过程。

下面结合特定的技术细节，概括地说明根据本发明的一种延迟判定方法和机制，具体如下：
当多卡终端的处于连接态的第一SIM卡正在与第一网络通信时，处于空闲态的第二SIM卡由于周期性注册更新定时器超时需要进行注册区域更新，但是多卡终端为了不影响第一SIM卡的通信而决定不让第二SIM卡进行由于周期性注册更新定时器超时而导致的注册区域更新，则第二SIM卡可以向第二网络发送忙指示。
如果移动可达定时器没有超时，如果忙指示只是一个bit位的指示，则第二网络收到忙指示后会暂停移动可达定时器，并等待第二SIM卡发起注册区域更新。
如果移动可达定时器没有超时，如果忙指示同时指示了忙的时间，则第二网络收到忙指示后会暂停移动可达定时器，并启动忙计时器，在忙计时器超时后再重启移动可达定时器。
如果移动可达定时器超时，如果忙指示只是一个bit位的指示，则第二网络收到忙指示后会暂停隐式去注册定时器，并等待第二SIM卡发起注册区域更新。
如果移动可达定时器超时，如果忙指示同时指示了忙的时间，则第二网络收到忙指示后会暂停隐式去注册定时器，并启动忙计时器，在忙计时器超时后再重启隐式去注册定时器。
