背景技术
无线能力信令优化(Radio Capability Signaling Optimization,RACS)是第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)第十六版本(Release 16,Rel16)引入的对终端设备和网络都是可选的优化特性,目的是为了优化空口上终端无线能力传输信令,其工作机制是用一个用户设备(User Equipment,UE)(也可称为终端设备)无线能力标识来代替UE当前激活的无线能力,该UE无线能力标识可以由运营商网络分配,也可以由终端制造商分配。
在相关技术中,支持RACS的UE需要向网络提供其支持RACS的能力指示,而支持RACS的网络无需向UE提供支持RACS的能力指示。具体地,若支持RACS的UE有可用的UE无线能力标识,则UE在初始注册或者UE能力标识发生改变时,才通过注册请求消息向网络提供UE当前的UE无线能力标识。
然而,实际应用中可能存在支持RACS的网络节点与不支持RACS的网络节点共存的情况,当UE在不支持RACS的网络节点和支持RACS的网络节点之间移动时UE的无线能力可能发生改变,进而导致UE侧和网络节点侧的UE无线能力标识不匹配的问题,影响UE和网络的正常通信。

步骤201、在满足网络节点变更相关条件的情况下,向网络节点发送终端设备当前可用的第一无线能力标识。
本实施例中,上述网络节点变更相关条件可以包括网络节点变更条件和 网络节点可能变更条件。上述网络节点变更条件可以理解为会导致网络节点变更的触发条件,也即在满足该网络节点变更条件的情况下网络节点会发生变更。

上述第一无线能力标识可以是指终端设备无线能力ID,可以用于指示支持RACS的终端设备当前可用的无线能力。
本实施例中,由于网络节点变更往往容易出现网络侧与UE的无线能力标识不一致,因此,通过在满足网络节点变更相关条件的情况下向网络节点发送终端设备当前可用的第一无线能力标识,可以保证终端设备侧和网络节点侧的UE无线能力标识的一致性,减少当UE在不支持RACS的网络节点和支持RACS的网络节点之间移动时UE侧和网络节点侧的UE无线能力标识不匹配的情况出现,进而可以保证UE和网络节点之间正常通信。
可选地,终端设备向网络节点发送所述终端设备当前可用的第一无线能力标识之后,若该网络节点支持RACS,则该网络节点可以在向终端设备发送的消息中携带终端设备无线能力标识,否则可以不携带终端设备无线能力标识。例如,终端设备通过注册请求消息向网络节点发送第一无线能力标识,若该网络节点支持RACS,则该网络节点可以在向终端设备发送的注册接受消息中携带该第一无线能力标识,否则不在向终端设备发送的注册接受消息中携带该第一无线能力标识。进而终端设备可以基于网络节点发送的消息中是否携带有终端设备无线能力标识以判断网络节点是否支持RACS,以确定是否启用RACS。
需要说明的是,在网络节点支持RACS的情况下,网络节点可以在满足一定条件下才向终端设备发送无线能力标识,例如,可以在从终端设备接收 的无线能力标识与终端设备当前的无线能力不匹配的情况下,向终端设备发送无线能力标识。

可选地,上述步骤201之后,也即所述向网络节点发送所述终端设备当前可用的第一无线能力标识之后,所述方法还可以包括:
接收所述网络节点发送的第二无线能力标识;
其中,所述第二无线能力标识与所述终端设备当前的无线能力匹配。
本实施例中,上述第二无线能力标识可以与第一无线能力标识相同,也可以与第一无线能力标识不同。例如,可以在第一无线能力标识与终端设备当前的无线能力匹配的情况下,第二无线能力标识与第一无线能力标识相同,可以在第一无线能力标识与终端设备当前的无线能力不匹配的情况下,第二无线能力标识与第一无线能力标识不相同。
本实施例中通过终端设备从网络节点接收与所述终端设备当前的无线能力匹配的无线能力标识,不仅可以在保证终端设备侧和网络节点侧的终端设备无线能力标识一致,还可以保证终端设备无线能力标识与终端设备当前的无线能力匹配。
可选地,所述接收所述网络节点发送的第二无线能力标识,可以包括:
接收所述网络节点通过第二消息发送的第二无线能力标识;

本公开实施例提供一种无线能力标识传输方法,应用于网络节点,所述网络节点为第一网络节点,所述第一网络节点支持RACS。参见图3,图3是本公开实施例提供的无线能力标识传输方法的流程图,如图3所示,包括以下步骤:
步骤301、在终端设备支持RACS且第二网络节点不支持RACS的情况下,向所述终端设备发送第三无线能力标识;
其中,所述第三无线能力标识与所述终端设备当前的无线能力匹配。
本实施例中,上述第一网络节点可以是新网络节点,例如移动后的网络节点;上述第二网络节点可以是旧网络节点,例如移动前的网络节点。第一网络节点和第二网络节点均可以包括AMF或MME等网络实体,例如,对于5G移动通信系统,上述第一网络节点和第二网络节点均可以为AMF;对于4G移动通信系统,上述第一网络节点和第二网络节点均可以为MME。

实际应用中,UE从不支持RACS的第二网络节点移动至支持RACS的第一网络节点,第一网络节点可以从UCMF获取之前分配给UE的UE无线能力标识,由于UE在附着在不支持RACS的网络节点下时可能改变了UE的无线能力,从而会导致UE侧和第一网络节点侧当前的UE无线能力标识不匹配。
本实施例通过在终端设备支持RACS且第二网络节点不支持RACS的情况下,第一网络节点向终端设备发送与所述终端设备当前的无线能力匹配的无线能力标识,可以保证终端设备侧和网络节点侧的UE无线能力标识的一致性,解决当UE在不支持RACS的网络节点和支持RACS的网络节点之间移动时UE侧和网络节点侧的UE无线能力标识不匹配的问题,进而可以保证UE和网络节点之间正常通信。

本实施例中,上述第三信息和第四信息可以对应,例如,若上述第四消息为注册请求消息,上述第三消息可以为注册接受消息;若上述第四消息为安全模式完成消息,上述第三消息可以为TAU接受消息。
本实施例第一网络节点通过注册请求消息或安全模式完成消息发送第四无线能力标识,可以节省信令和资源。
可选地,所述接收所述终端设备发送的第四无线能力标识之前,所述方 法还包括:
向所述终端设备发送携带有终端设备无线能力标识请求信元的安全模式命令。
本实施例中,第一网络节点可以在Security Mode Command消息中携带UE Radio Capability ID Request IE并发送给UE,从而UE可以在接收到携带UE Radio Capability ID Request IE的Security Mode Command的情况下向第一网络节点发送UE无线能力标识,从而可以提高UE无线能力标识发送的安全性。
以下结合示例对本公开实施例进行说明:
示例一:在5G移动通信系统的应用。
方式一:可以在UE满足如下网络节点变更相关条件下,在支持RACS的UE在注册请求消息中携带当前可用的UE无线能力ID。
上述网络节点变更相关条件可以包括如下至少一项:
移出当前TA List;
在Intersystem Change触发的注册请求过程中;
UE选择了新的PLMN;
UE从网络节点接收的配置更新命令消息中携带有值为1的注册请求比特时。
方式二:可以在每次发起注册更新过程时,支持RACS的UE在注册请求消息中携带当前可用的UE无线能力ID。
示例二:在5G系统的应用,或者从MME移动到AMF时的应用。
在发生AMF Change(即AMF变更)的注册更新过程中,若UE支持RACS且从源侧网络节点(或者称为旧网络节点)获取的UE上下文中没有UE的无线能力ID,则支持RACS的目标AMF在注册更新接受消息中携带为UE分配的与当前UE无线能力匹配的UE无线能力ID。
其中,当前UE无线能力可以从源AMF获取,也可以从下一代无线接入网络(Next Generation-Radio Access Network,NG-RAN)获取。
示例三:在长期演进(Long Term Evolution,LTE)移动通信系统的应用,或者从MME移动到AMF时的应用。
在发生MME Change(即MME变更)的TAU过程中,若UE支持RACS且从源侧网络节点(或者称为旧网络节点)获取的UE上下文中没有UE的无线能力ID,则支持RACS的目标MME发起SECURITY MODE COMMAND过程,并在SECURITY MODE COMMAND中携带UE Radio Capability ID Request IE。
这样UE可以在接收到携带UE Radio Capability ID Request IE的SECURITY MODE COMMAND的情况下,向目标MME发送UE无线能力ID。支持RACS的目标MME在TAU接受消息中携带为UE分配的与当前UE无线能力匹配的UE无线能力ID。
