Abstract
A communications system is capable of knowing presence status of mobile communications devices such as cellular transceivers. An access gateway such as, for example, a PDSN access gateway or home agent access gateway, manages access to a mobile communications device. The access gateway knows the presence status of the mobile communications device and reports it to a presence server. The access gateway can know the presence status using attributes obtained during management of system operation by the access gateway.
Claims22
A communications system capable of knowing presence status of mobile communications devices, comprising:
- an access gateway for managing access to a mobile communications device, wherein the access gateway knows the presence status of the mobile communications device;
- and
- a presence server operatively connected to the access gateway to receive the presence status for the mobile communications device.
A method in an access gateway for facilitating the transmission of presence status of mobile communications devices in a communications system, said method comprising the steps of:
- (a) managing access to a mobile communications device,
- (b) learning the presence status of the mobile communications device;
- and
- (c) transmitting the presence status for the mobile communications device to a presence server in the communications system.
A method in a presence server for obtaining the presence status of mobile communications devices in a communications system, said method comprising the steps of:
- (a) receiving the presence status of the mobile communications device from an access gateway in the communications system;
- (b) storing the presence status of the mobile communications device;
- and
- (c) managing presence status information among elements of the communications system based on the stored presence status of the mobile communications device.
