Abstract

The present invention is related to registering a user equipment (UE) with a communication network. The present invention comprises registering a UE with a communication network by transmitting a registration request message to the communication network and receiving a registration response message from the communication network, wherein the registration response message comprises information related to a registration validity period. A session initiation protocol (SIP) message is then transmitted to the communication network, wherein the UE is re-registered with the communication network if the SIP message is received by the communication network before the expiration of the registration validity period.

Claims

1. A method of registering a user equipment (UE) with a communication network, the method comprising:

registering a UE with a communication network by transmitting a registration request message to the communication network and receiving a registration response message from the communication network, wherein the registration response message comprises information related to a registration validity period; and

transmitting a session initiation protocol (SIP) message to the communication network, wherein the UE is re-registered with the communication network if the SIP message is received by the communication network before the expiration of the registration validity period.

2. The method of claim 1, wherein the UE is re-registered by extending the registration validity period.

3. The method of claim 1, wherein the SIP message comprises a re-registration request.

4. The method of claim 3, wherein the UE registration is canceled if one of the SIP message and the re-registration message is not received by the communication network before the expiration of the registration validity period.

5. The method of claim 1, wherein the communication network is an Internet Protocol Multimedia Subsystem (IMS) network.

6. The method of claim 1, wherein a communication network element having a call session control function re-registers the UE.

7. The method of claim 1, wherein the UE is re-registered by extending the registration validity period based on registration request information included in the SIP message.

8. The method of claim 7, wherein the registration validity period is varied according to the registration request information.

9. The method of claim 1, wherein the registration validity period is set differently for certain time periods of a day.

10. A method of registering a user equipment (UE) with a communication network, the method comprising:

registering a UE with a communication network by receiving a registration request message from the UE and transmitting a registration response message to the UE, wherein the registration response message comprises information related to a registration validity period;

receiving a session initiation protocol (SIP) message from the UE; and

re-registering the UE with the communication network if the SIP message is received by the communication network before the expiration of the registration validity period.

11. The method of claim 10, wherein re-registering the UE comprises extending the registration validity period.

12. The method of claim 10, wherein the SIP message comprises a re-registration request.

13. The method of claim 12, further comprising canceling the UE registration if one of the SIP message and the re-registration message is not received by the communication network before the expiration of the registration validity period.

14. The method of claim 10, wherein the communication network is an Internet Protocol Multimedia Subsystem (IMS) network.

15. The method of claim 10, wherein a communication network element having a call session control function re-registers the UE.

16. The method of claim 10, wherein re-registering the UE comprises extending the registration validity period based on registration request information included in the SIP message.

17. The method of claim 16, wherein the registration validity period is varied according to the registration request information.

18. The method of claim 10, wherein the registration validity period is set differently for certain time periods of a day.

19. A system for registering a user equipment (UE) with a network, the system comprising:

a network having a network element; and

a UE in communication with the network;

wherein the UE registers with the network by transmitting a registration request message to the network element and receiving a registration response message from the network element, the registration response message comprising information related to a registration validity period;

wherein the UE transmits a session initiation protocol (SIP) message to the network element, and the network element re-registers the UE with the network if the SIP message is received by the network element before the expiration of the registration validity period.

20. The system of claim 19, wherein the network element re-registers the UE by extending the registration validity period.

21. The system of claim 19, wherein the SIP message comprises a re-registration request.

22. The system of claim 21, wherein the network element cancels the UE registration if one of the SIP message and the re-registration message is not received by the network element before the expiration of the registration validity period.

23. The system of claim 19, wherein the network is an Internet Protocol Multimedia Subsystem (IMS) network.

24. The system of claim 19, wherein the network element comprises a call session control function.

25. The system of claim 19, wherein the network element re-registers the UE by extending the registration validity period based on registration request information included in the SIP message.

26. The system of claim 25, wherein the registration validity period is varied according to the registration request information.

27. The system of claim 19, wherein the registration validity period is set differently for certain time periods of a day.
