Patent ID: 8848880

Claim:
A method for communication comprising: coupling a wireless telephone network and a data network through a gateway; and coordinating user presence information between a first communication system including a first presence system maintaining presence information using a first presence model and hosted on the wireless telephone network and a second communication system including a second presence system maintaining presence information using a second presence model and hosted on the data network through the gateway, wherein the coordinating includes one or more of the following: translating, by the gateway, first user presence information stored in a storage device in the wireless telephone network in association with a first user from the first presence model of the first presence system to the second presence model of the second presence system, the first user presence information being indicative of a presence in the first communication system of the first user on the wireless telephone network, and forwarding, by the gateway, the translated first user presence information to the data network to effect a storing of the translated first user presence information in a storage device in the data network, wherein subsequent to the storing, the first user on the wireless telephone network appears to users of the first communication system to be present in the first communication system hosted on the wireless telephone network and appears to users of the second communication system to be present in the second communication system hosted on the data network; and translating, by the gateway, second user presence information stored in the storage device in the data network in association with a second user from the second presence model to the first presence model, the second user presence information being indicative of a presence in the second communication system of the second user on the data network, and forwarding, by the gateway, the translated second user presence information to the storage device in the wireless telephone network to effect a storing of the translated second user presence information in the storage device in the wireless telephone network, wherein subsequent to the storing, the second user on the data network appears to users of the first communication system to be present in the first communication system hosted on the wireless telephone network and appears to users of the second communication system to be present in the second communication system hosted on the data network.
