Abstract:
1. A method, comprising: communicating presence information by presence update signaling messages from a device to a presence server that is capable of receiving presence updates relating to the device and that, in response thereto, determines a presence state at a given time and that is also capable of receiving service announcements from other devices in communication with one or more network entities using ad-hoc, peer-to-peer, service discovery protocols of a local network that are different from out-of-band communications over a wide area network, and receiving signaling messages using the out-of-band communications over the wide area network from the one or more network entities indicative of altered service discovery data available to the device from the other devices, wherein the altered service discovery data represents the service announcements received by the one or more network entities from the other devices altered by the one or more network entities based on the presence state determined by the one or more network entities.
