Automatic call origination for multiple wireless networks
First Claim
1. An apparatus comprising:
- at least one processor configured to attempt origination of a packet-switched voice call on a first wireless network, and to attempt origination of a circuit-switched voice call on a second wireless network if the packet-switched voice call fails; and
a memory coupled to the at least one processor.

Abstract
Techniques for performing automatic call origination for multiple wireless networks are described. A terminal automatically originates a call and supports fallback in case of call origination failure. The terminal selects the most preferred wireless network for the call based on network availability and network selection information. The terminal attempts origination of the call on the selected wireless network. If the call origination fails, then the terminal may select an alternate wireless network based on network availability and the network selection information and may attempt origination of the call on the alternate wireless network. If a VoIP call is preferred over a circuit-switched voice call, then the terminal may first attempt origination of a VoIP call on a packet-switched wireless network. If the VoIP call fails, then the terminal may attempt origination of a circuit-switched voice call on a circuit-switched wireless network.
