  • Cells 2 and 3 are serving cells of gNB2.
  • Step 3 During the handover process of UE1, the current AMF will obtain the association relationship between UE1 and UE2 from the original AMF (old AMF);
  • Step 4 UE2 triggers registration update (periodic registration or when cell 3 does not belong to RA), and generates a first NAS message container, which contains at least one of the following:
  • Registration request proxy registration update indication, UE2 5G-S-TMSI, and information related to the cell where UE2 currently resides (such as the last visted TAI, selected PLMN, cell 3 ID). These information help the network side Know the latest TAI of UE2 or the cell where it is located);
  • Step 5 UE2 sends the first NAS message container to UE1 through the internal interface of the multi-card terminal or the interface between terminals;
  • Step 6 After UE1 receives the interface message, it sends an RRC message to gNB2, where the first NAS message container is nested in the NAS message container (such as the second NAS message container) of UE1;
  • Step 7 After receiving the RRC message from UE1, gNB2 transparently transmits the NAS information container of UE1 to AMF.
  • Step 8 The AMF receives the first NAS message container, and obtains the UE2 registration request or proxy registration update indication. It is judged whether UE2 is still in the registration area, and if it is not, a NAS message of UE2 is generated and sent to UE2 through UE1.

  • Step 6 After receiving it, UE1 will send a first message to gNB2, which contains proxy indication information or the first RRC message container;
  • Step 7 After receiving the first message, gNB2 obtains the proxy indication information of UE2 or the first RRC message container therein. According to the I-RNTI of the RRCResumerequest message, gNB2 finds gNB1;
  • Step 8 gNB2 sends an Xn message to gNB1, which contains UE2's I-RNTI, UE2’s camping cell ID, and RNA update indication information;
  • Step 9 gNB1 judges whether UE2 is still in the RNA configured by gNB1. If it is still there, gNB1 sends an RRCRelease message to UE2 through gNB2. If not, gNB2 carries the new notification area configuration in the RRCRelease message sent to UE2.
  • Step 10 The RRCRelease message of UE2 can be sent through UE1.

假设UE2处于idle态,UE1处于连接态。
步骤1:UE1和UE2驻留在小区1,小区1为gNB1的服务小区;
步骤2:由于多卡终端的移动性,UE1切换到小区2,UE2重选到小区3,小区2和3为gNB2的服务小区。
步骤3:UE1执行切换过程中,当前AMF将从原AMF(old AMF)处获取UE1和UE2的关联关系;
步骤4:UE2触发注册更新(周期性注册或小区3不属于RA时),生成第一NAS消息容器,其中包含以下至少一项:
注册请求、代理注册更新指示、UE2 5G-S-TMSI、与UE2当前驻留小区相关的信息(如the last visted TAI、所选的PLMN、小区3的ID),这些信息有助于让网络侧知道UE2最新的TAI或所在小区);
步骤5:UE2将第一NAS消息容器通过多卡终端内部接口或终端间的接口发送给UE1;
步骤6:UE1收到接口消息后,发送RRC消息给gNB2,其中将第一NAS消息容器嵌套在UE1的NAS消息容器(如第二NAS消息容器)中;
步骤7:gNB2收到UE1的RRC消息后,透传UE1的NAS信息容器给AMF。
步骤8:AMF接收第一NAS消息容器,获取UE2的注册请求或代理注册更新指示。判断UE2是否还在注册区域,如果不在,则生成UE2的NAS消息,通过UE1发送给UE2。UE2的NAS消息中包含以下至少一项:
注册接收消息,其中包含新的注册区域;UE2标识;一个字段(如proxy-RA-update),用于配置注册区域相关的信息。
步骤9:UE1通过多卡终端内部接口或终端间的接口将UE2的NAS消息发送给UE2;
步骤10:UE2获取NAS消息。如果其中出现了新的TAI list,则UE应用新的配置;如果没有出现,则UE仍然使用保存的RA配置;
需要说明的是,对于LTE的TAU过程,上述gNB为ng-eNB、注册请求为TAU Request、注册接受改为TAU accept,其他过程类似,不再赘述。
实施例三:
该实施例,以代理RNAU流程进行举例说明:
假设UE2处于inactive态,UE1处于连接态。
步骤1:UE1和UE2驻留在小区1,为gNB1的服务小区;
步骤2:由于多卡终端的移动性,UE1切换到小区2,UE2重选到小区3,小区2和3为gNB2的服务小区。
步骤3:UE1执行切换时,gNB1将UE1和UE2的关联关系发送给gNB2;
步骤4:UE2触发RNAU流程,一个代理指示信息用于指示代理RNA更新或第一RRC消息容器。第一RRC消息容器中包含以下至少一项:UE2标识、RRCResumerequest消息(恢复原因值设为rna-update)、小区3的ID;
步骤5:UE2将代理指示信息或第一RRC消息容器通过多卡终端内部接口或终端间的接口发送给UE1;
步骤6:UE1收到后,将发送第一消息给gNB2,其中包含代理指示信息或第一RRC消息容器;
步骤7:gNB2收到第一消息后,获取其中的UE2的代理指示信息或第一RRC消息容器。根据其中的RRCResumerequest消息的I-RNTI,gNB2找到gNB1;
步骤8:gNB2给gNB1发送Xn消息,其中包含UE2 I-RNTI、UE2驻留小区ID、RNA更新指示信息;
步骤9:gNB1判断UE2是否还在gNB1配置的RNA内。如果还在,则gNB1通过gNB2给UE2发送RRCRelease消息。如果不在,则gNB2在给UE2发送的RRCRelease消息中携带新的通知区域配置。
步骤10:UE2的RRCRelease消息可以通过UE1发送下去。
需要说明的是,上述流程重用了RRCResumerequest和RRCRelease消息。还可以直接在UE2的RRC消息容器中携带UE2 I-RNTI、UE2驻留小区ID、RNA更新指示信息。当gNB2收到UE2的第二信息容器时,根据其中的UE2 I-RNTI找到UE2的gNB1,将RNA更新指示信息和UE2驻留小区ID发送 给gNB1。gNB1判断后,如果不需要更新,可通过gNB2给UE2发送一个指示。如果需要更新,则由gNB2给UE2重新配置新的RNA配置,并通过UE1下发给UE2。
实施例四:
该实施例,以代理RRC连接建立/恢复流程,节省UE2的PRACH过程进行举例说明:
具体的UE2可以使用下述方法与所在网络建立/恢复RRC连接。
步骤1:当UE 2要发起RRC连接建立/恢复流程时,如果UE1具有上行同步和可用的上行资源时,则UE2生成第二信息,其中包含UE2 ID(5G-S-TMSI/I-RNTI/LocalID)、第一RRC信息容器。第一RRC消息容器包含RRC连接建立/恢复请求消息)和/或代理指示信息,其中,代理指示信息用于指示代理RRC连接建立/恢复请求;
步骤2:UE2将UE2的第二信息通过多卡终端内部接口或终端间的接口发送给UE1;
步骤3:UE1发送UE1的第一消息,其中携带UE2的代理指示信息或第一RRC信息容器;
步骤4:当gNB收到了UE 1第一消息后,获取UE2的代理指示信息或第一RRC消息容器;
步骤5:UE 1收到了gNB发送的RRC消息,其中携带了UE 2的RRC连接建立/恢复消息。可选地,在该消息中为UE 2分配一个C-RNTI;
步骤6:通过内部接口,UE 1将收到的RRC连接建立/恢复消息传递给UE 2;
步骤7:UE 2在网络2发送RRC连接建立/恢复完成消息,进入了RRC连接态,开始在网络2进行数据的收发。
实施例五:
该实施例包括以下步骤:
步骤1:UE2将以下其中一项或多项发送给UE1:
UE2的信令或NAS消息容器;
UE2的数据包;
UE2的服务核心网网元的相关信息;
UE2的接入网网元(N3IWF)的IP地址;
步骤2:UE1生成UE1的数据包,其中携带UE1的IP地址,UE2的接入网网元(N3IWF)的IP地址,UE2的信令(或NAS消息容器)和/或数据包、UE2的服务核心网网元的相关信息中的一个或多个。
步骤3:UE1通过隧道将UE1的数据包发送给UE2的接入网网元(N3IWF),其中隧道为UE1与UE2的接入网网元(N3IWF)之间的逻辑通道;
步骤4:UE2的接入网网元(N3IWF)收到了UE1的数据包,其中携带UE2的信令和/或数据包,N3IWF具有UE1和UE2的关联关系。
步骤5:N3IWF根据UE1的数据包中的内容(如UE2的服务核心网网元的相关信息)将UE2的信令和/或数据包发送给UE2的服务核心网网元(AMF或UPF)。
该实施例中的隧道可以使用3GPP网络或非3GPP网络建立。例如UE1向服务基站发送用户面数据,服务基站将UE1的数据发送至UPF,UPF将UE1的数据包转发到数据网络,最后N3IWF收到UE1的数据包。或者,UE1向非3GPP网络发送IPsec tunnel数据,非3GPP网络将UE1的数据包转发至N3IWF。这些过程都直接或间接形成了UE1与N3IWF之间的发送信息的通道。
