Description

一种会话管理方法和装置
本申请要求在2017年6月6日提交中国专利局、申请号为201710418244.5、发明名称为“一种会话管理方法和装置”以及在2017年8月9日提交中国专利局、申请号为201710677595.8、发明名称为“一种会话管理方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及一种会话管理方法和装置。
背景技术
MME(Mobility Management Entity，移动管理实体)和5G(The Fifith Generation Mobile Network，第五代移动通信)系统中的AMF(access control and mobility management Function，接入控制和移动性管理功能)之间的Nx接口是可选支持的，当移动网络中支持Nx接口时，就可以支持5G系统和EPS(Evolved Packet System，演进的分组系统)系统之间的切换，此时MME和AMF之间需要传递用户终端的上下文信息，包括移动性上下文和会话连接的上下文。终端接入这种支持Nx接口的网络时，网络可能将其注册模式配置为单注册模式(single registration mode)，目前单注册模式是强制要求终端支持的工作模式。
当移动网络不支持Nx接口时，5G系统和LTE(Long Term Evolution，长期演进)系统之间不支持切换，此时为了支持互操作，移动网络需要要求终端进行双注册模式(dual registration mode)，即同时在5G系统和EPS系统中保持注册。考虑到双注册模式下业务连续性的支持，要求网络中的控制面的SMF(Session Management Function，会话管理功能)同时支持PGW-C(PDN GateWay-Control，分组数据网关的控制面)的功能，这样通过切换注册(Handover registration)，可以保证终端在EPS系统和5G系统之间移动时， 其会话连接始终锚定在相同的用户面锚点上。
双注册的终端又进一步分为SR(single radio，单无线射频)能力和DR(dual radio，双无线射频)能力的。SR的终端在同一时刻，只能保持一侧的会话连接，即要么在EPS系统中保持连接，要么在5G系统中保持连接，这样如果终端在EPS系统和5G系统间移动时，将不可避免的出现丢包，无法保证无缝的业务连续性。而DR的终端可以在EPS系统和5G系统中同时保持连接，因此在移动网络中的不同系统间移动时，可以采用先接后断(make-before-break)的方式进行连接的切换，即从目标网络接收数据的同时，仍会从源侧网络接收数据，从而可以保证业务的连接。
由于终端可以和网络协商使用单注册模式还是双注册，因此在相同网络中，可能存在使用不同注册模式的终端；即使网络统一支持了一种互操作模式，但在实际网络部署中，支持PGW-C功能的SMF具有网关锚点的控制功能，不仅可以服务本运营商家网络，还可以在漫游场景下服务于其他运营商拜访网络，而运营商家网络和拜访网络也可能支持不同的互操作模式。
当服务单模式的终端时，支持PGW-C功能的SMF需要在会话建立过程中进行QoS(Quality of Service，服务质量)映射；当服务双注册模式的终端时，支持PGW-C功能的SMF不需要进行QoS映射。
因此，现有技术中存在如下技术问题：支持PGW-C功能的SMF并不能识别终端的注册模式并加以区分处理，或者SMF并不能确定接收到终端发送的会话请求到的AMF是否支持互操作能力，因此，当终端在移动网络中建立会话连接时，所述SMF不能确定是否需要执行QoS映射，若所述SMF总是执行QoS映射，则对于双注册模式的终端将造成不必要的信令过程。

具体实施方式
为了解决上述技术问题，本发明实施例中涉及会话管理的技术方案主要包括：接收会话建立请求；确定发送所述会话建立请求的终端的注册模式；根据所述终端的注册模式，确定在为所述终端创建会话连接时是否完成不同系统间QoS参数的映射。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
参见图1，本发明实施例一提供了一种会话管理方法，应用于移动网络，所述方法包括：
S101，确定发送会话建立请求的终端的注册模式，或者确定接收到终端发送的会话建立请求的网络侧设备是否支持互操作能力；
S102，在所述注册模式为单注册模式，或者在所述网络侧设备支持互操作能力时，确定在为所述终端创建会话连接时完成不同系统间QoS参数的映射。
具体地，S101，具体如下：
根据AMF提供的所述终端的注册模式信息，确定所述终端为单注册模式或者双注册模式。具体地，SMF根据接收到的AMF在转发所述会话建立请求时提供的所述终端的注册模式信息，确定所述终端的注册模式。或者SMF可以根据接收到的AMF在响应所述SMF的会话管理请求时返回的所述终端的注册模式，确定所述终端的注册模式。或者根据接收到的所述终端在会话 建立请求消息中携带的注册模式信息，确定所述终端为单注册模式或者双注册模式。在此之前，在S101之前，还可以包括步骤接收会话建立请求。
或者，根据接收到所述会话建立请求的接入控制和移动性管理功能实体AMF是否支持互操作接口，确定所述接入控制和移动性管理功能实体AMF是否支持互操作能力。
或者，接收服务所述终端的接入控制和移动性管理功能实体AMF的指示，或者服务所述终端的拜访网络的会话管理功能实体SMF的指示，确定所述接入控制和移动性管理功能实体AMF是否支持互操作能力。所述服务所述终端的拜访网络的会话管理功能实体SMF的指示，可以包括：所述拜访网络的会话管理功能实体SMF在创建会话请求中携带的用于表征所述接入控制和移动性管理功能实体AMF是否支持互操作能力指示；或者所述拜访网络的会话管理功能实体SMF提供的用于表征EPS系统承载标识的指示。
其中，SMF支持PGW-C功能。
另外，对于S101中确定终端的注册模式，在终端的移动过程中，终端的注册模式可能会发生更新；如果所述终端的注册模式发生变化，根据接收到的AMF提供的所述终端的变化后的注册模式，确定所述终端的注册模式。
在执行完S101后，继续执行S102，S102具体包括：
当所述终端的注册模式为单注册模式时，完成不同系统间QoS参数的映射。具体地，当所述终端的注册模式为单注册模式时，执行移动网络中5G系统和EPS系统间的QoS参数的映射。或者，当接入控制和移动性管理功能实体AMF支持互操作接口时，完成不同系统间QoS参数的映射。
如果会话连接在5G系统中建立，将所述会话连接对应的QoS参数映射为EPS系统的QoS参数；如果会话连接在EPS系统中建立时，将所述会话连接对应的QoS参数映射为5G系统的QoS参数。
另外，当所述终端的注册模式为双注册模式时，不完成不同系统间QoS参数的映射。具体地，当所述终端的注册模式为双注册模式时，不执行移动网络中5G系统和EPS系统间的QoS参数的映射。
由于采用了该实施例中的技术方案，在终端的注册模式为单注册模式即终端只在5G系统或者EPS系统中注册时或者网络侧设备支持互操作能力时，通过执行中5G系统和EPS系统间的QoS参数的映射，可以保证终端在EPS系统和5G系统之间移动时，终端的会话连接始终锚定在相同的用户面锚点上；在终端的注册模式为双注册模式时，即终端同时在5G系统或者EPS系统中注册时，终端的会话连接始终锚定在相同的用户面锚点上，则不需要执行移动网络中5G系统和EPS系统间的QoS参数的映射。因此，终端在移动网络中不同系统间移动时，仍然能够保证终端的会话连接的持续性。
为了更好的理解本发明，进一步举例说明，参见图2，图2是终端的会话建立过程中的会话管理方法，包括：
S201，AMF和终端协商并确定终端的注册模式；
S202，SMF通过AMF接收终端发起的会话连接请求，在SMF接收终端发起的会话连接请求后，SMF需要确定发送会话连接请求的终端的注册模式，有两种确定终端的注册模式的方式。
两种确定终端的注册模式的方式可以是：
方式一，根据AMF提供的终端的注册模式信息进行确定。
具体可以为，终端首先发出会话建立请求消息，AMF向SMF转发所述会话建立请求消息时，向该SMF指示该发送会话建立请求的终端的注册模式信息；或者SMF可以根据接收到的AMF在响应所述SMF的会话管理请求时返回的所述终端的注册模式，确定所述终端的注册模式。
方式二，根据终端提供的注册模式信息进行确定。
具体可以为，SMF在接收所述终端的会话建立请求时，该终端发送的会话建立请求消息中携带有该终端的注册模式信息。
S203，SMF根据所述终端的注册模式，确定在为所述终端创建会话连接时是否完成不同系统间QoS参数的映射。具体的确定方式与前述S102中的确定方式相同。
参见图3，图3中终端已经建立了支持在5G系统和EPS系统间切换的会 话连接，具体的会话管理方法，包括：
S301，建立会话连接；
S302，在终端的移动过程中，终端执行注册更新过程；
S303，在所述注册更新过程中，当所述终端的注册模式发生变化时，SMF根据接收到的AMF提供的所述终端的变化后的注册模式，确定所述终端的注册模式。
其中，确定终端的注册模式的方式包括：
方式一，AMF在确定终端的注册模式发生变化后，根据终端的上下文信息中的会话连接对应的SMF的ID(标识)，确定支持互操作的SMF；AMF向支持互操作的SMF通知变化后的注册模式；SMF据此确定终端的变化后的注册模式。
方式二，终端在确定自身的注册模式发生变化后，发起会话修改过程通知SMF其注册模式发生变化；SMF据此确定终端的变化后的注册模式。若SMF支持互操作，则继续执行S304。
S304，SMF根据所述终端的变化后的注册模式，确定在为所述终端创建会话连接时是否完成不同系统间QoS参数的映射。具体的确定方式与前述S102中的确定方式相同。
参见图4，在PDU(Packet Data Unit，分组数据单元)会话建立过程中对PDU会话管理的具体的执行步骤如下：
S401，AMF收到终端发出的PDU会话建立请求；
S402，AMF请求SMF创建PDU会话，在会话建立请求中向SMF指示自身是否支持互操作能力。
S403，SMF根据AMF提供的该AMF是否支持互操作能力，即是否支持N26接口，判断是否完成不同系统间QoS参数的映射。在AMF支持互操作能力时，完成不同系统间的QoS参数的映射。
S404，按照现有流程完成PDU会话建立。
或者，进一步参见图5A，在PDU会话建立过程中对PDU会话管理的具 体的执行步骤如下：
S501A，UE(User Equipment，用户设备)在拜访网络VPLMN(拜访地PLMN；PLMN：Public Land Mobile Network，公共陆上移动网)中发起PDU会话建立过程，拜访网络的AMF收到UE发出的PDU会话建立请求。
S502A，若AMF确定需要为UE建立到归属地SMF的PDU会话，即PDU会话的锚点在归属地网络，则AMF按照现有技术选择V-SMF(拜访地SMF)和H-SMF(归属地SMF)，然后发送会话建立请求到V-SMF，请求消息中可以携带网络支持的互操作能力，即AMF是否支持N26接口。
S503A，V-SMF收到AMF的请求后，向H-SMF发送创建会话请求，请求中携带该拜访网络中的AMF是否支持互操作能力的提示，该提示可以从AMF处接收，也可以基于V-SMF上的静态配置获得，例如V-SMF在创建会话请求中携带的所述接入控制和移动性管理功能实体AMF是否支持互操作能力指示，或者V-SMF提供的EPS系统的承载标识的指示。
S504A，H-SMF收到V-SMF的创建会话请求后，根据AMF是否支持互操作能力，即AMF是否支持N26接口，判断是否完成不同系统间的QoS参数的映射。在AMF支持互操作能力时，完成不同系统间的QoS参数的映射。
S505A，按照现有流程完成PDU会话建立。
或者，进一步参见图5B，在PDU会话建立过程中对PDU会话管理的具体的执行步骤如下：
S501B，UE发起PDU会话建立过程；
S502B，AMF收到UE发出的PDU会话建立请求后，发送PDU会话建立请求到SMF。如果UE此时位于拜访网络，则AMF将PDU会话建立请求发送到V-SMF。
S503B，SMF或V-SMF收到请求后，向AMF发送消息，请求AMF为该会话分配EBI(EPS bearer ID，EPS承载标识)。
S504B，AMF根据其支持的互操作能力确定是否为PDU会话分配EBI，若AMF支持N26接口，则分配，否则不分配。分配结果通过响应返回给SMF 或V-SMF。
S505B，SMF根据EBI分配情况，确定是否进行到EPS系统的QoS参数映射，若分配，则执行，否则不执行。V-SMF根据EBI分配情况，确定网络支持的互操作能力，然后将网络支持的互操作能力和/或EBI发送至H-SMF。
S506B，若H-SMF从V-SMF接收到EBI，则执行到EPS系统的QoS参数映射，若收到网络支持的互操作能力指示不支持N26，则不进行到EPS系统的QoS参数映射。
S507B，按照现有流程完成PDU会话建立。
参见图6，本发明实施例二提供了一种会话管理装置，应用于移动网络，所述装置包括：
第一确定模块601，用于确定发送会话建立请求的终端的注册模式或者确定接收到终端发送的会话建立请求的网络侧设备是否支持互操作能力；

或者所述第一确定模块601具体用于：根据接收到所述会话建立请求的接入控制和移动性管理功能实体AMF是否支持互操作接口，确定所述接入控制和移动性管理功能实体AMF是否支持互操作能力。
或者所述第一确定模块601具体用于：
接收服务所述终端的接入控制和移动性管理功能实体AMF的指示，或者服务所述终端的拜访网络的会话管理功能实体SMF的指示，确定所述接入控制和移动性管理功能实体AMF是否支持互操作能力。其中所述服务所述终端的拜访网络的会话管理功能实体SMF的指示，包括：所述拜访网络的会话管理功能实体SMF在创建会话请求中携带的用于表征所述接入控制和移动性管理功能实体AMF是否支持互操作能力指示；或者所述拜访网络的会话管理功能实体SMF提供的用于表征EPS系统承载标识的指示。
其中，SMF支持PGW-C功能。
另外，该会话管理装置还包括第三确定模块，在终端的移动过程中，终端的注册模式可能会发生更新；所述第三确定模块，用于如果所述终端的注册模式发生变化，根据接收到的接入控制和移动性管理功能实体AMF提供的所述终端的变化后的注册模式，确定所述终端的注册模式。
所述第二确定模块602还用于当所述终端的注册模式为单注册模式时，完成不同系统间QoS参数的映射。具体地，当所述终端的注册模式为单注册模式时，执行移动网络中5G系统和EPS系统间的QoS参数的映射。或者所述第二确定模块602具体用于当接入控制和移动性管理功能实体AMF支持互操作接口时，完成不同系统间QoS参数的映射。
如果会话连接在5G系统中建立，将所述会话连接对应的QoS参数映射为EPS系统的QoS参数；如果会话连接在EPS系统中建立时，将所述会话连接对应的QoS参数映射为5G系统的QoS参数。
另外，当所述终端的注册模式为双注册模式时，不执行不同系统间QoS参数的映射。具体地，当所述终端的注册模式为双注册模式时，不执行移动网络中5G系统和EPS系统间的QoS参数的映射。
该实施例中会话管理装置的工作原理与前述会话管理方法相同，在此不再赘述。
由于采用了该实施例中的技术方案，在终端的注册模式为单注册模式即 终端只在5G系统或者EPS系统中注册时或或者在网络侧设备支持互操作能力时，通过执行中5G系统和EPS系统间的QoS参数的映射，可以保证终端在EPS系统和5G系统之间移动时，终端的会话连接始终锚定在相同的用户面锚点上；在终端的注册模式为双注册模式时，即终端同时在5G系统或者EPS系统中注册时，终端的会话连接始终锚定在相同的用户面锚点上，则不需要执行移动网络中5G系统和EPS系统间的QoS参数的映射。因此，终端在移动网络中不同系统间移动时，仍然能够保证终端的会话连接的持续性。
