Abstract:
Methods and apparatus enabling a wireless network to implement efficient and robust paging channel operation. In one aspect, the invention permits recovery of a paging channel after a virtual connection failure. A virtually connected UMTS cellular phone that misses a paging notification will no longer be synchronized with its serving radio network, and the resultant loss of synchronization causes a service “blackout” until the devices are resynchronized. Accordingly, in one embodiment, a virtually connected cellular device continuously monitors for fallback messaging, greatly expediting detection and correction of a virtual connection failure. In another embodiment, a virtually connected base station which is unable to page a cellular device in a virtually connected mode continues paging in both virtual connection and fallback modes, thereby provoking an immediate response from the cellular device.
