Abstract:
Techniques for determining if it is safe for a mobile device to transition directly from a traffic session to a paging mode and for avoiding network re-synchronization procedures in stationary M2M devices are disclosed. It may be safe for direct transition if before-call and in-call network parameters correspond. If safe, the mobile device may transition from the traffic session directly to the paging mode to begin immediately monitoring the paging channel. In stationary M2M devices, paging information is stored before the traffic session and, once the traffic session is complete, the M2M device may be configured to receive paging messaging based on the stored paging information. The M2M device may also store system access information and confirm the validity of the information before returning to the sleep state. The stationary M2M device avoids network re-synchronization procedures. Other aspects, embodiments, and features are also claimed and described.
