Wireless Chat Automatic Status Signaling

摘要

A technique and apparatus to provide status tracking of presence and/or location of wireless devices to requesting entities inside and/or outside a particular wireless system. Presence and/or location information is provided to entities outside a particular servicing wireless network via mechanisms of call processing components of a mobile network and standard mechanisms available to any appropriately conforming MSC element. In one embodiment, a wireless chat automatic status tracking system utilizes a change in mobile registration status to automatically forward or copy a registration notification (REGNOT) message to an external IP application, to notify a chat group system outside the wireless network of current status information activity regarding a relevant device. Change in mobile registration is communicated via a suitable signaling link between a HLR and the chat group system. REGNOT messages are pushed over TCP/IP connections to external applications to automatically notify the external system of a particular user's location.
