Description

会话管理方法、设备及系统
本申请要求于2018年2月2日提交中国国家知识产权局、申请号为201810108388.5、发明名称为“会话管理方法、设备及系统”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
本申请涉及通信技术领域，尤其涉及会话管理方法、设备及系统。
背景技术
为了应对无线宽带技术的挑战，保持第三代合作伙伴计划(3rd generation partnership project，3GPP)网络的领先优势，3GPP标准组在2016年底制定了下一代移动通信系统(next generation system)网络架构，称为第五代(5rd generation，5G)网络架构。
目前的5G网络架构支持三种会话类型，分别是：互联网协议(internet protocol，IP)会话、以太会话、以及非结构化会话。其中，在终端的每个以太会话建立的过程中，5G网络不分配终端的通信地址，即不分配终端IP地址和终端媒体访问控制(media access control，MAC)地址，而是由5G网络架构中的会话管理功能(session management function，SMF)网元从数据网络(data network，DN)-认证、授权和计费(authentication，authorization and accounting，AAA)服务器获取可用的终端MAC地址列表，并根据该可用的终端MAC地址列表设置用户面功能(user plane function，UPF)网元的过滤规则(filtering rule)。进而，若该UPF网元检测到接收到的数据包中的终端MAC地址不在该终端的已有以太会话可用的终端MAC地址列表中，则丢弃该数据包。
然而，以太会话由于编码限制或者标准定义限制，单个以太会话支持的终端MAC地址有限，如标准中定义单个以太会话从DN-AAA服务器获取的可用的终端MAC地址列表中的终端MAC地址的个数不超过16个。但是终端支持的终端MAC地址并不确定，比如终端支持的终端MAC地址的数量可能超过终端的已有以太会话可用的终端MAC地址列表中的终端MAC地址的数量，或者终端支持的终端MAC地址可能不在终端的已有以太会话可用的终端MAC地址列表中，此时应该如何处理，目前并没有相关的解决方案。

以图1或者图2所示的会话管理系统应用于如图3所示的5G网络为例，如图5所示，为本申请实施例提供的一种会话管理方法，该会话管理方法包括如下步骤：
S501、终端向AMF网元发送注册请求，以使得AMF网元接收来自终端的注册请求。
进而，AMF网元可以通过如下步骤S502a-S502c获取终端的以太会话可绑定的终端MAC地址的个数和终端支持的终端MAC地址列表中的至少一个。
S502a、AMF网元从UDM网元获取终端的签约数据。
S502b、AMF网元从PCF网元获取终端的策略数据。

其中，步骤S502a-S502c中的终端的签约数据、终端的策略数据、或者终端的数据网络认证数据中的至少一个中包括终端的以太会话可绑定的终端MAC地址的个数和终端支持的终端MAC地址列表中的至少一个。本实施例中，终端支持的终端MAC地址用于以太会话，在此统一说明，以下不再赘述。
示例性的，终端的签约数据中包括终端的以太会话可绑定的终端MAC地址的个数和终端支持的终端MAC地址列表；或者，终端的策略数据中包括终端的以太会话可绑定的终端MAC地址的个数和终端支持的终端MAC地址列表；或者，终端的数据网络认证数据中包括终端的以太会话可绑定的终端MAC地址的个数和终端支持的终端MAC地址列表；或者，终端的签约数据中包括终端的以太会话可绑定的终端MAC地址的个数，终端的策略数据中包括终端支持的终端MAC地址列表；或者，终端的签约数据中包括终端的以太会话可绑定的终端MAC地址的个数，终端的数据网络认证数据中包括终端支持的终端MAC地址列表；或者，终端的签约数据中包括终端支持的终端MAC地址列表，终端的策略数据中包括终端的以太会话可绑定的终端MAC地址的个数；或者，终端的签约数据中包括终端支持的终端MAC地址列表，终端的数据网络认证数据中包括终端的以太会话可绑定的终端MAC地址的个数；或者，终端的策略数据中包括终端的以太会话可绑定的终端MAC地址的个数，终端的数据网络认证数据中包括终端支持的终端MAC地址列表；或者，终端的策略数据中包括 终端支持的终端MAC地址列表，终端的数据网络认证数据中包括终端的以太会话可绑定的终端MAC地址的个数；或者，仅终端的签约数据中包括终端的以太会话可绑定的终端MAC地址的个数；或者仅终端的签约数据中包括终端支持的终端MAC地址列表；或者，仅终端的策略数据中包括终端的以太会话可绑定的终端MAC地址的个数；或者仅终端的策略数据中包括终端支持的终端MAC地址列表；或者，仅终端的数据网络认证数据中包括终端的以太会话可绑定的终端MAC地址的个数；或者仅终端的数据网络认证数据中包括终端支持的终端MAC地址列表，等等，本实施例对此不作具体限定。
进一步的，本实施例提供的会话管理方法还包括如下步骤：
S503、AMF网元向终端发送注册响应，以使得终端接收来自AMF网元的注册响应。其中，该注册响应中携带获取的终端的以太会话可绑定的终端MAC地址的个数和终端支持的终端MAC地址列表中的至少一个。
可选的，也可以在终端上配置终端的以太会话可绑定的终端MAC地址的个数或终端支持的终端MAC地址列表中的至少一个。比如，可以在终端上配置终端支持的终端MAC地址列表，这样注册响应中可以不携带终端支持的终端MAC地址列表；或者，可以在终端上配置终端的以太会话可绑定的终端MAC地址的个数，这样注册响应中可以不用携带终端的以太会话可绑定的终端MAC地址的个数。
需要说明的是，本实施例中，若未在终端上配置终端支持的终端MAC地址列表，则需要在注册响应中携带终端支持的终端MAC地址列表，即AMF网元需要获取终端支持的终端MAC地址列表，然后将终端支持的终端MAC地址列表携带在注册响应中发送给终端。也就是说，本实施例中，终端需要获取终端支持的终端MAC地址列表。
可选的，若未在终端上配置终端的以太会话可绑定的终端MAC地址的个数，则还可以通过如下方式获取终端的以太会话可绑定的终端MAC地址的个数，包括如下步骤S504-S508：
S504、终端向SMF网元发送会话建立请求消息，以使得SMF网元接收来自终端的会话建立请求消息。
进而，SMF网元可以通过如下步骤S505a-S505c获取该以太会话可绑定的终端MAC地址的个数。
S505a、SMF网元从UDM网元获取终端的签约数据。
S505b、SMF网元从PCF网元获取终端的策略数据。

S508、SMF网元向终端发送会话建立接受消息，以使得终端接收来自SMF网元的会话建立接受消息。其中，该会话建立接受消息携带该以太会话可绑定的终端MAC地址的个数。
需要说明的是，上述步骤504-S508给出了以太会话建立的流程，当然，以太会话建立时还可能包括其他的流程，具体可参考现有的以太会话建立流程，在此不予赘述。
综上，也就是说，本实施例中，终端的以太会话可绑定的终端MAC地址的个数可以是通过步骤S501-S503的注册流程获取的，也可以是通过步骤S504-S508的以太会话建立流程获取的，还可以是配置在终端上的，本实施例对此不作具体限定。其中，通过步骤S504-S508的以太会话建立流程获取的终端的以太会话可绑定的终端MAC地址的个数是该以太会话可绑定的终端MAC地址的个数；通过步骤S501-S503的注册流程获取的终端的以太会话可绑定的终端MAC地址的个数和配置在终端上的终端的以太会话可绑定的终端MAC地址的个数可以是针对该终端的所有以太会话均适用的，在此统一说明，以下不再赘述。
至此，通过上述方式终端可以获取到终端的以太会话可绑定的终端MAC地址的个数以及终端支持的终端MAC地址列表。进一步的，本实施例提供的会话管理方法还包括如下步骤：
S509、终端确定检测到新的终端MAC地址，这里假设为该新的MAC地址为第一终端MAC地址。
可选的，本实施例中，终端可以在以下几种场景下确定检测到新的终端MAC地址：
比如，该终端为中继(relay)终端，在新的远端(remote)终端接入的情况下，该中继终端可以确定检测到新的终端MAC地址；或者，
该终端接收到上行数据包，但是没有匹配其上行数据包中的终端MAC地址的服务质量(quality of service，QoS)规则，此时该终端可以确定检测到新的终端MAC地址；或者，
该终端接收到上行数据包，虽然有匹配其上行数据包中的终端MAC地址的QoS规则，但是该QoS规则没有以太包过滤器(QoS rule with no ethernet Packet filter)，此时该终端可以确定检测到新的终端MAC地址；
或者，该终端接收到下行数据包，但是该下行数据包中的终端MAC地址未在终端的已有以太会话已绑定的终端MAC地址列表中，等等。
当然，上述仅是示例性的提供几种终端确定检测到新的终端MAC地址的可能情形，终端还可能通过其他方式确定检测到新的终端MAC地址，本实施例对此不作具体限定。
S510、终端验证第一终端MAC地址的合法性。
可选的，本实施例中，若该第一终端MAC地址在终端支持的终端MAC地址列表中，则终端确定第一终端MAC地址合法，进而执行后续步骤；若该第一终端MAC地址不在终端支持的终端MAC地址列表中，则终端确定第一终端MAC地址不合法，直接丢弃，进而不会执行后续操作，在此统一说明，以下不再赘述。
S511、在终端确定该终端的已有以太会话已绑定的终端MAC地址列表中终端MAC地址的个数与终端的已有以太会话可绑定的终端MAC地址的个数不相同的情况下，终端将该第一MAC地址与该终端的已有以太会话绑定，即将该第一终端MAC地址存储到该终端的已有以太会话已绑定的终端MAC地址列表中。
其中，本实施例中，终端的已有以太会话可绑定的终端MAC地址的个数可以是通过步骤S501-S503的注册流程获取的终端的以太会话可绑定的终端MAC地址的个数或者配置在 终端上的终端的以太会话可绑定的终端MAC地址的个数；也可以是在建立该已有以太会话的过程中，通过步骤S504-S508的以太会话建立流程获取的该已有以太会话可绑定的终端MAC地址的个数，本实施例对此不作具体限定。
其中，本实施例中，终端的已有以太会话已绑定的终端MAC地址列表中终端MAC地址的个数与终端的已有以太会话可绑定的终端MAC地址的个数不相同是指，终端的该已有太会话已绑定的终端MAC地址未满，也即终端确定不需要为该终端建立新的以太会话，在此统一说明，以下不再赘述。
示例性的，在将该第一终端MAC地址存储到该终端的已有以太会话已绑定的终端MAC地址列表中之后，该终端的已有以太会话已绑定的终端MAC地址列表可以如表一所示：
表一
以太会话标识 已绑定的终端MAC地址
以太会话1 xxxxxxxx
以太会话1 xxxxxxxx
…… ……
以太会话2 xxxxxxxx
以太会话2 第一终端MAC地址
…… ……
当然，终端的不同以太会话可能分别对应不同的列表，比如以下会话1和以太会话2分别对应以下表二和表三，本实施例对此不作具体限定。
表二
以太会话1已绑定的终端MAC地址
xxxxxxxx
xxxxxxxx
……
表三

xxxxxxxx
第一终端MAC地址
……
可选的，本实施例中，终端将该第一终端MAC地址与该终端的已有以太会话绑定时，可能存在一个或多个已绑定的终端MAC地址未满的该终端的已有以太会话。其中，当仅有一个已绑定的终端MAC地址未满的该终端的已有以太会话时，可以直接将第一终端MAC地址与该已绑定的终端MAC地址未满的该终端的已有以太会话绑定；当有多个已绑定的终端MAC地址未满的该终端的已有以太会话时，终端可以从多个已绑定的终端MAC地址未满的该终端的已有以太会话中选择一个已有以太会话与第一终端MAC地址进行绑定，在此统一说明，本实施例对此不作具体限定。
S512、在终端确定该终端的已有以太会话已绑定的终端MAC地址列表中终端MAC地址的个数与终端的已有以太会话可绑定的终端MAC地址的个数相同的情况下，终端发起为该终端建立新的以太会话。其中，新的以太会话建立的流程可参考上述步骤S504-S508，在此不再赘述。
其中，本实施例中，终端的已有以太会话已绑定的终端MAC地址列表中终端MAC地址的个数与终端的已有以太会话可绑定的终端MAC地址的个数相同是指，终端的该已有太会话已绑定的终端MAC地址已满，也即终端确定需要为该终端建立新的以太会话，在此统一说明，以下不再赘述。
基于本申请实施例提供的会话管理方法，由于该会话管理方法中，终端可以获取该终端的以太会话可绑定的终端MAC地址的个数，并在根据该终端的以太会话可绑定的终端MAC地址的个数，确定需要为该终端建立新的以太会话之后，发起为该终端建立新的以太会话，因此可以解决目前终端的单个以太会话支持的终端MAC地址有限，但是终端支持的终端MAC地址并不确定的问题。
其中，上述步骤S501至S512中的终端或者SMF网元或者AMF网元的动作可以由图4所示的通信设备400中的处理器401调用存储器403中存储的应用程序代码来执行，本实施例对此不作任何限制。
