Abstract
In a wireless communication system, a user equipment (UE) may be capable of communication on multiple radio access networks. A UE may be in simultaneous communication with one radio access network, such as TD-SCDMA for circuit-switched voice calls and with another radio access network, such as TDD-LTE for packet-switched data communications. When the TDD-LTE network is idle, the UE may evaluate signal strength of the respective network for potential cell reselection. The UE may measure only a serving TD-SCDMA cell for purposes of switching packet-switched service to the TD-SCDMA network, thereby avoiding a situation where the UE attempts to connect to a different TD-SCDMA cell for purposes of packet-switched communications than the cell presently affiliated with the UE for circuit-switched communications.
