METHODS AND APPARATUS FOR PRIORITIZING VOICE CALL REQUESTS DURING DATA COMMUNICATION SESSIONS WITH A MOBILE DEVICE

摘要

Methods and apparatus for prioritizing voice call requests during data communication sessions involving a mobile communication device are disclosed. In one illustrative example, an end user invokes a voice call request though a user interface of the mobile device. If this request is made while the mobile device is engaged in a connected data communication service, the mobile device immediately forces the connected da ta service into a dormant state. In particular, a release order is transmitted to tear down a traffic channel of the connected data service so that the voice call request can be processed. Subsequently, a voice call with the mobile device is established using a new traffic channel . When the voice call is completed, data communications will resume if needed. Advantageously , the mobile device prioritizes voice calls over data communication sessions which may be deemed less time-critical.
