Abstract

A technique and apparatus to provide status tracking of presence and/or location of a mobile, wireless device to a requesting entity even outside of a particular wireless system. This allows wireless service providers the ability to monitor and log changes in the status of mobile stations within and/or outside their networks. Embodiments are disclosed wherein presence and/or location information is provided to entities outside of a particular servicing wireless network using the mechanisms of call processing components of a mobile network (e.g., call setup procedures), and using standard mechanisms currently available to any appropriately conforming Mobile Switching Center (MSC) element. In one disclosed embodiment, a wireless chat tracking system is implemented which utilizes a change in mobile registration status to automatically notify a chat group system outside the wireless network of current status information activity regarding a relevant device, e.g., registration activity or inactivity timeout. In the wireless chat automatic status tracking system, a registration notification (REGNOT) message is either explicitly forwarded or copied to an external IP based application (e.g., to a mobile chat group system). The change in mobile registration is communicated via a suitable signaling link (e.g., SS7, TCP/IP, etc.) between a Home Location Register (HLR) and the chat group system. Therefore, instead of a conventionally closed system using SS7 messages, REGNOT messages are pushed out over TCP/IP connections to external applications (e.g., chat servers) to automatically notify the external system of the location of a particular user.

Claims

1-31. -31. (canceled)

32. A mobile device status tracking system, comprising:

a registration notification message receiver to receive a registration notification message from a home location register;

a chat server to notify subscribers of a chat group of a particular subscriber'"'"'s chat group status; and

a registration notification message forwarder to forward said registration notification message received by said registration notification message receiver over an Internet Protocol (IP) connection to said chat server;

wherein said chat server automatically notifies said chat group of said particular subscriber'"'"'s chat group status in response to receipt of said registration notification message.

33. The mobile device status tracking system according to claim 32, wherein:

said IP connection is an Internet connection.

34. The mobile device status tracking system according to claim 32, wherein:

said registration notification message forwarder copies all registration notification messages received by a mobile switching center.

35. The mobile device status tracking system according to claim 32, further comprising:

a wireless Internet gateway to transmit said forwarded notification message over said IP connection.

36. The mobile device status tracking system according to claim 35, further comprising:

a registration notification message handler to communicate with said wireless Internet gateway using a Signaling System #7 communications protocol.

37. The mobile device status tracking system according to claim 32, wherein:

said registration notification message is a previously forwarded registration notification message by a Home Location Register (HLR).

38. A method of tracking a status of a mobile device, comprising:

receiving a registration notification message from a home location register at a registration notification message receiver;

notifying, from a chat server, subscribers of a chat group of a particular subscriber'"'"'s chat group status; and

forwarding, from a registration notification message forwarder, said registration notification message received by said registration notification message receiver over an Internet Protocol (IP) connection to said chat server;

automatically notifying, from said chat server, said chat group of said particular subscriber'"'"'s chat group status in response to receipt of said registration notification message.

39. The method of tracking a status of a mobile device according to claim 38, wherein:

said IP connection is an Internet connection.

40. The method of tracking a status of a mobile device according to claim 38, further comprising:

copying, with said registration notification message forwarder, all registration notification messages received by a mobile switching center.

41. The method of tracking a status of a mobile device according to claim 38, further comprising:

transmitting from a wireless Internet gateway said forwarded notification message over said IP connection.

42. The method of tracking a status of a mobile device according to claim 41, further comprising:

establishing communications from a registration notification message handler and said wireless Internet gateway using a Signaling System #7 communications protocol.

43. The method of tracking a status of a mobile device according to claim 38, wherein:

said registration notification message is a previously forwarded registration notification message by a Home Location Register (HLR).

47. The apparatus for tracking a status of a mobile device according to claim 43, further comprising:

means for transmitting from a wireless Internet gateway said forwarded notification message over said IP connection.

48. The apparatus for tracking a status of a mobile device according to claim 47, further comprising:

means for establishing communications from a registration notification message handler and said wireless Internet gateway using a Signaling System #7 communications protocol.

49. The apparatus for tracking a status of a mobile device according to claim 47, wherein:

said registration notification message is a previously forwarded registration notification message by a Home Location Register (HLR).

44. Apparatus for tracking a status of a mobile device, comprising:

means for receiving a registration notification message from a home location register at a registration notification message receiver;

means for notifying, from a chat server, subscribers of a chat group of a particular subscriber'"'"'s chat group status; and

means for forwarding, from a registration notification message forwarder, said registration notification message received by said registration notification message receiver over an Internet Protocol (IP) connection to said chat server;

means for automatically notifying, from said chat server, said chat group of said particular subscriber'"'"'s chat group status in response to receipt of said registration notification message.

45. The apparatus for tracking a status of a mobile device according to claim 44, wherein:

said IP connection is an Internet connection.

46. The apparatus for tracking a status of a mobile device according to claim 44, further comprising:

means for copying, with said registration notification message forwarder, all registration notification messages received by a mobile switching center.
