Title:
無線プレゼンスベースサービスを可能にするための無線通信ネットワークおよびその方法
Document Type and Number:
Japanese Patent JP4820955
Kind Code:
B2
Abstract:
The need to enable wireless presence-based services more efficiently is addressed by embodiments of the present invention. A wireless presence proxy (WPP 415) monitors the messaging and messaging responses of a mobile station (MS 401) via wireless transceiver equipment (411). Such messaging and messaging responses do not explicitly specify a presence state or state change for the MS. Thus, based upon this monitoring, the WPP infers the presence state / change for the MS and maintains MS location information. The WPP communicates any presence state changes and confirms MS presence state as required by the presence server(s) (225). By monitoring messaging, notifying the server(s) of MS presence, and handling server requests (potentially from many servers for the same MS), embodiments of the present invention reduce or avoid many existing inefficiencies, such as wide area paging and call set up and tear down for each presence ping, from each presence server.
