Obtaining caller ID on second SIM of multi-SIM user equipment

The disclosure relates to obtaining a caller ID on a second SIM of a multi-SIM user equipment. A user equipment (UE) configured to initiate a first voice call using a first network associated with a first subscriber identity module (SIM) of the UE; receiving, from a second network, a paging request indicating an incoming voice call associated with a second SIM of the UE, wherein the paging request is received while the first voice call is in an active state; performing a radio resource control (RRC) connection establishment with the second network; transmitting, to the second network, an indication that the UE should be configured to have a single component carrier (CC); and exchanging a session information protocol (SIP) message with the second network to retrieve a caller identification (ID) of the incoming call. 本公开涉及在多SIM的用户装备的第二SIM上获得呼叫者ID。一种用户装备(UE)，该UE被配置为：利用与该UE的第一用户身份模块(SIM)相关联的第一网络发起第一语音呼叫；从第二网络接收指示与该UE的第二SIM相关联的传入语音呼叫的寻呼请求，其中在该第一语音呼叫处于活动状态时接收到该寻呼请求；执行与该第二网络的无线电资源控制(RRC)连接建立；向该第二网络传输该UE应被配置为具有单个分量载波
