Call transfer for an integrated wireline and wireless service using a temporary directory number

Abstract

The present invention relates to a communication environment where calls are established with a single mobile terminal through either a wireless network or the public switched telephone network (PSTN) via a terminal adaptor, which is capable of wirelessly communicating with the mobile terminal. As such, the mobile terminal may facilitate traditional cellular calls via the wireless network, or traditional PSTN calls via the terminal adaptor. A temporary directory number for the mobile terminal is provided by the wireless network and used for facilitating calls via the wireless network. The terminal adaptor, supporting telephony switch, and wireless network will cooperate to transfer calls to the wireless network as necessary or desired.
