Abstract: A multi-subscriber identification module (SIM) wireless communication device with a first SIM and a second SIM associated with a shared radio frequency (RF) resource may determine that timing collisions are predicted between an active period of a discontinuous reception (DRX) cycle associated with the first SIM and an active period of a DRX cycle associated with the second SIM. In response, the wireless communication device may determine whether the first SIM is registered with an IP Multimedia Subsystem (IMS) to use Voice-over-wireless local area network (VoWLAN) service over a wireless local area network (WLAN). If the first SIM is registered with the IMS to use VoWLAN service over the WLAN, the wireless communication device may shift the conflicting DRX cycle associated with the first SIM by a time margin, and receive paging messages for mobile terminating calls on the modem stack associated with the first SIM over the WLAN.
