  • Patent number: 8934899
    Abstract: A user equipment is provided comprising: 1) transceiver circuitry configured to operate in cells associated with at least one radio access technology (RAT) network; and 2) a controller configured to perform neighbor cell searches. The controller is further configured to determine when the user equipment enters a first RRC state from a second RRC state. In response to the determination, the controller determines a time period since a most recent search of neighbor cells was performed. The first RRC state is one of at least: CELL_PCH, URA_PCH and IDLE. The second RRC state is one of at least CELL_FACH and CELL_DCH.
