Abstract

Techniques for optimizing presence information update requests for wireless devices on a wireless communication network by reducing the amount of access-network resources are provided. In an exemplary embodiment, presence information updates can be optimized by a presence module that is a single point of contact on a mobile device for presence requests from presence aware applications.
