Abstract

The present invention provides for the delivery of presence information to a service node from a mobile terminal using a messaging service, such as the short messaging service. The mobile terminal is configured to communicate via a cellular network as well as via a terminal adaptor, which is coupled to a wireline telephony switch or a data access network to support telephony communications. A local wireless interface is provided between the mobile terminal and the terminal adaptor to support communications through the terminal adaptor. In operation, the mobile terminal will provide a messaging service message including presence information to the service node, wherein the presence information will bear on the ability of the mobile terminal to communicate with the terminal adaptor, and thus, facilitate communications through the terminal adaptor.
