Abstract

A presence service access device is disclosed for a presentity to publish presence information and transmit said information to the presence server, the device comprising a presentity communication module and a service scheduling control module. Further disclosed is a presence service system using the presence service access device, comprising a presentity, a presence service access device, a presence server, and a watcher client. Also disclosed is a method of publishing and acquiring presence information comprising steps of: 1. a presentity which publishes presence information; 2. the presence service access device which receives the presence information published by the presentity and forwards the same to a presence server; and 3. the presence server which distributes the presence information to corresponding watcher client. According to the present invention, various presentities provide presence information to watcher clients by connecting presence servers through a presence service access device.

Claims

1. A presence service access device for accessing a presentity to a presence server, comprising:

a presentity communication module configured to detect whether presence information from the presentity matches a predefined mode definition; and

a service scheduling control module configured to distribute the presence information to the presence server based on a correspondence relationship between presentities and presence servers.

2. The device of claim 1, further comprising:

a connection control module communicated with the presentity communication module, configured to perform identity authentication for the presentity which transmits the presence information to the connection control module, and forward the presence information published by the presentity which passes the identity authentication to the presentity communication module.

3. The device of claim 1, further comprising:

a presence server communication module communicated with the scheduling control module and the presence server, respectively, configured to perform traffic control over the presence information distributed by the service scheduling control module to the presence server based on service volume.

4. The device of claim 1, further comprising:

a management information base configured to store system data, the stored data being used by modules in the presence service access device.

5. The device of claim 4, further comprising:

a system management module configured to perform service management and system control for the presence service access device and maintain the data stored in the management information base.

6. The device of claim 3, further comprising:

a protocol conversion module configured to perform communication protocol conversion in response to the presentity communication module, or the presence server communication module receives and distributes the presence information.

7. The device of claim 3, further comprising:

a charging processing module configured to receive confirmation information returned by the presence server subsequent to publishing the presence information;

generate an original call detail record and a charging record of the presence service based on the confirmation information, and transmit a charging file to a charging center.

8. A presence service system, comprising:

a presentity configured to transmit presence information to a presence service access device;

a presence service access device configured to receive the presence information published by the presentity and transmit the presence information to a presence server based on a correspondence relationship between presentities and presence servers;

a presence server configured to receive and store the presence information transmitted by the presence service access device and distribute the presence information to a watcher client; and

a watcher client configured to receive the presence information distributed by the presence server.

9. The system of claim 8, wherein the presence service access device comprises:

a presentity communication module configured to detect whether the received presence information matches a predefined mode definition; and

a service scheduling control module configured to distribute the presence information to the presence server based on the correspondence relationship between the presentities and the presence servers.

10. The system of claim 8, further comprising:

a tandem device configured to interconnect presence service access devices in the presence service system and store routing information, the presence information being forwarded among the presence service access devices based on the routing information.

11. A method for publishing and acquiring presence information, comprising the following steps:

A. receiving and forwarding, via the presence service access device, the presence information published by a presentity to a presence server based on a correspondence relationship between presentities and presence servers; and

B. distributing, via the presence server, the presence information to a corresponding watcher client.

12. The method of claim 11, wherein the step A further comprising:

A1. receiving, via the presence service access device, the presence information;

A2. verifying, via the presence service access device, the presence information based on a predefined mode definition; and

A3. transmitting, via the presence service access device, the presence information passing the verification to the presence server based on the correspondence relationship between presentities and presence servers.

13. The method of claim 12, wherein after the step A1, the method further comprising a step of performing, via the presence service access device, identity authentication for the presentity which publishes the presence information.

14. The method of claim 12, wherein prior to the step A3, the method further comprises:

A11. acquiring, via the presence service access device, routing information from a tandem device; and

A12. forwarding, based on the routing information, the presence information to the presence service access device corresponding to the presence server to which watcher clients to receive the presence information belong.

15. The method of claim 14, wherein the routing information comprises a subscription relationship between watchers and presentities, an ascription relationship between watchers and presence servers, and data of correspondence relationship between presence servers and presence service access devices,

step A12 further comprises:

determining a corresponding watcher, which subscribes the published presence information of the presentity, based on the subscription relationship;

determining a corresponding presence server based on the determined watcher and the ascription relationship between watchers and presence servers; and

determining a corresponding presence service access device based on the determined presence server and the data of the correspondence relationship between presence servers and presence service access devices.

16. The method of claim 14, wherein the routing information comprises a correspondence relationship between presence servers and presentities for denoting there is at least one watcher belonging to the presence server which subscribes to the presence information of the presentity, and a correspondence relationship between presence servers and presence service access devices,

step A12 further comprises:

determining a presence server that the corresponding watcher to which subscribes the presentity publishing the presence information belongs, based on the correspondence relationship between presence servers and presentities; and

determining a corresponding presence service access device, based on the determined presence server and the correspondence relationship between presence servers and presence service access devices.

17. The method of claim 11, wherein the method further comprises a step of generating charging information in which the presence server generates an original call detail record and transmits the original call detail record to a charging center after successful information transmission.

18. The method of claim 11, wherein the method further comprises a step of generating charging information, in which the presence server returns the presence service access device a response message, including a list of watchers of successful transmission or unsuccessful transmission, after successful transmission of the presence information to the watcher client;

and the presence service access device generates an original call detail record and transmits it to a charging center based on the received message.
