Abstract: Techniques are disclosed relating to handover between cellular base stations. In some embodiments that use dual-connectivity handover, disclosed techniques may facilitate synchronization of a security configuration switch. In some embodiments, the base station and/or mobile device determine activation sequence numbers for the security configuration switch (e.g., by estimating when a path switch will occur). In some embodiments, the security configuration switch is implicitly detected based in deciphering failure. In some embodiments, the security configuration switch is explicitly signaled and is checked based on deciphering failure. In some embodiments that use make before break handover techniques, a source base station may be retained after the path switch.

Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

Abstract: A user equipment UE configured to initiate a first voice call with a first network associated with a first subscriber identity module SIM1 of the UE, receive a paging request from a second network indicating an incoming voice call associated with a second SIM2 of the UE, wherein the paging request is received while the first voice call is active, perform a radio resource control RRC connection setup with the second network and perform one of accepting the incoming voice call or rejecting the incoming voice call, provide an indication to the second network that dual connectivity DC carrier aggregation CA should be suspended such that the second network only configures the UE with a single component carrier CC on the SIM2 and exchanging SIP messages with the second network to retrieve a caller identification ID of the incoming call from the SIM2
