Embodiment Construction

[0016] The present invention provides a method and apparatus for providing presence updates to mobile subscribers. According to one embodiment, the present invention reduces the amount of network traffic by eliminating the need for explicit messaging to notify users that updates exist. In addition, the present invention merges the user's presence information and sends only the changed part of the presence information to the user. Therefore, users who obtain presence information can choose when to receive updates, and only receive the latest information.

[0017] figure 1 An example network 10 in which the present invention may be used is illustrated. Network 10 includes a plurality of mobile devices 100, a radio access network 12 for communicating with mobile devices 100, and a radio core network 14 providing connectivity to the Internet 18 or other packet data networks. The radio access network 12 preferably comprises a packet-switched network, such as a GPRS, cdma2000, WC...

Abstract

A network node provides presence updates to mobile users. The node reduces the amount of network traffic by eliminating the need for explicit messaging used to inform a user of presence updates. Additionally, the node reduces network traffic by consolidating presence updates, and sending the user only changed portions of the presence information.

Description

[0001] This application claims priority to US Provisional Patent Application 60 / 884,299, filed January 10, 2007, which is hereby incorporated by reference. technical field [0002] The present invention relates generally to presence services for mobile devices, and more particularly to updating mobile devices with presence information. Background technique [0003] Initially, cellular networks were developed to provide voice services over circuit-switched networks. Although circuit-switched networks are still widely used, the current trend is towards packet-switched networks that provide high-speed packet data services in addition to voice services. These high-speed packet data services generally allow mobile users to enjoy the same types of things that Internet users can do on fixed networks. [0004] One such service is instant messaging (IM). Desktop IM has gained wide acceptance when used in conjunction with a fixed network. Currently, there are more than 100 million ...
