Title:
VOICE AND DATA CONNECTION CONTROL IN A MOBILE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/094524
Kind Code:
A3
Abstract:
Controlling non-simultaneous voice and data connections between a mobile wireless device and a wireless network is described. Following a voice connection origination failure between the mobile wireless device and the wireless network, the mobile wireless device sends a voice connection redial request only after closing an existing data connection between the mobile wireless device and the wireless network. The mobile wireless device tunes a wireless transceiver to a second voice connection channel radio frequency that differs from a first data connection channel radio frequency and establishes a voice connection with the wireless network on the second voice connection channel radio frequency.
