1. A method of causing a network cell transition for a mobile device at call initiation, the method comprising:

  • detecting a call initiation event at the mobile device;

    in response to detecting the call initiation event, evaluating a radio signal power associated with a serving network base station to determine whether the mobile device is to transition from the serving network base station to a neighbor network base station prior to establishing a voice call associated with the call initiation event;

    transitioning the mobile device from the serving network base station to the neighbor network base station when the radio signal power associated with the serving network base station is less than a radio access technology (RAT) specific threshold; and

    establishing the voice call at the mobile device via the neighbor network base station after the network cell transition.
