Method and apparatus for reducing signaling spikes when moving between a WLAN coverage area and WWAN coverage area

摘要

When a user equipment connected to the network via a wireless wide area network (WWAN) connection (UE) is moved to a wireless local area network (WLAN) connection area, UE client-side high-level operating system ( HLOS) including to abandon the Internet protocol (IP) context, method and apparatus for wireless communication in a mobile device. Aspect of the present method and apparatus, when a UE connected to the network via a WWAN connection is moved to a WLAN connection area comprises maintaining a Packet Data Protocol (PDP) Context of UE. Aspect of the present method and apparatus includes a setting a ringer timer at a certain time in order to postpone the deactivation of the PDP context, and to deactivate the PDP context when ringer timer expires.
