Abstract
In some embodiments, a UE is configured to, in response to detecting an absence of received packets associated with a voice call over a first time interval of a pre-determined length, initiate transmission of a first control packet to a base station. In some embodiments, the UE is further configured, based on a response to the first control packet, not to drop the packet-switched voice call at least until expiration of a second time interval of a pre-determined length after transmission of the first control packet. In some embodiments, the absence of received packets is an absence of both voice and silence packets. In some embodiments, based on absence of a response to the first control packet, the UE is configured to drop the packet-switched call.
