Call transfer for an integrated wireline and wireless service
First Claim
1. A method for transitioning a call with a mobile terminal from a cellular connection to a local wireless connection, the method comprising:
- a) receiving a handoff request from a wireless switch supporting a call to the mobile terminal over a cellular access network, the call comprising a first connection from the wireless switch to the mobile terminal and a second connection between the wireless switch and a remote terminal;
b) effecting establishment of a third connection to the mobile terminal via a terminal adaptor, which supports local wireless communications with the mobile terminal; and
c) providing a handoff instruction to the wireless switch to connect the second and third connections to effect handoff of the call from the cellular connection to the local wireless connection.

Abstract
Calls are established with a single mobile terminal through either a wireless network or via a terminal adaptor over the PSTN or a packet network. The terminal adaptor and mobile terminal communicate via a local wireless interface. The mobile terminal may facilitate cellular calls via the wireless network as well as PSTN or packet-based calls via the terminal adaptor. The mobile terminal may initiate a handoff when it is involved in a call through the wireless network and within a communication zone of the terminal adaptor. The handoff will establish a connection between the wireless switch, which is currently supporting the call, and the mobile terminal through the terminal adaptor. Once the connection with the mobile terminal through the terminal adaptor is established, the call is transitioned to the new connection and the mobile terminal will transfer to the local wireless interface to support the call.
