Abstract
A mobile device is engaged in a connected data service via a wireless network. The connected data service utilizes a radio traffic channel established between the mobile device and the wireless network and a data session for communicating data. While engaged in the service, the mobile device receives via a user interface a voice call request for initiating a voice call. In response to the request, the mobile device permits the initiation of the voice call. Specifically, the mobile device causes the radio traffic channel for the connected data service to be torn down without terminating the data session. The mobile device also causes the voice call to be established and maintained over a new radio traffic channel via the wireless network while the data session for the data service is maintained.
