Abstract

A method, system and device for establishing connection based on a LTE/SAE system. First, e-NodeB sends an S1 SETUP REQUEST message to the MME, to initialize the establishment of the S1 connection; then, MME responds an S1 SETUP RESPONSE message to the e-NodeB, in response to the S1 SETUP REQUEST message, carrying the MME identification in the S1 SETUP RESPONSE message.

Claims

1. A method for establishing connection based on a Long Term Evolution/System Architecture Evolution, LTE/SAE, system, which is used for establishing an S1 connection between an evolved NodeB, e-NodeB, and a Mobility Management Entity, MME, wherein the method comprises:

the e-NodeB sending an S1 SETUP REQUEST message to the MME, to initialize the establishment of the S1 connection;

the MME returning an Si SETUP RESPONSE message to the e-NodeB in response to the Si SETUP REQUEST message, and carrying the MME identification in the Si SETUP RESPONSE message.

2. The method according to claim 1, wherein the method further comprises:

the e-NodeB determining the MME which sends the S1 SETUP RESPONSE message according to the MME identification.

3. The method according to claim 1, wherein the method further comprises:

the e-NodeB obtaining information from the MME which is determined.

4. The method according to claim 1, wherein the S1 SETUP REQUEST message carries the following information:

a message type, an e-NodeB identification, and a supported tracking area identity.

5. The method according to claim 1, wherein the S1 SETUP RESPONSE message further carries the following information:

the message type, and a supported identification of public land mobile network.

11. The method according to claim 2, wherein the S1 SETUP REQUEST message carries the following information:

a message type, an e-NodeB identification, and a supported tracking area identity.

12. The method according to claim 3, wherein the S1 SETUP REQUEST message carries the following information:

a message type, an e-NodeB identification, and a supported tracking area identity.

13. The method according to claim 2, wherein the S1 SETUP RESPONSE message further carries the following information:

the message type, and a supported identification of public land mobile network.

14. The method according to claim 3, wherein the S1 SETUP RESPONSE message further carries the following information:

the message type, and a supported identification of public land mobile network.

6. A system for establishing connection based on a Long Term Evolution/System Architecture Evolution, LTE/SAE, system, which comprises an evolved NodeB, e-NodeB, and a plurality of Mobility Management Entities, MMEs, wherein

the e-NodeB is configured to send an S1 SETUP REQUEST message to the MME, to initialize the establishment of the S1 connection;

and

the MME is configured to receive the S1 SETUP REQUEST message, and to return an S1 SETUP RESPONSE message, which carries the MME identification, to the e-NodeB.

7. The system according to claim 6, wherein the e-NodeB is further configured to receive the S1 SETUP RESPONSE message, and determine the MME which sends the S1 SETUP RESPONSE message according to the MME identification.

8. The system according to claim 7, wherein said e-NodeB is further configured to obtain information from the MME which is determined.

9. The system according to claim 6, wherein the S1 SETUP REQUEST message carries the following information:

a message type, an e-NodeB identification, and a supported tracking area identity;

the S1 SETUP RESPONSE message further carries the following information;

the message type, and a supported identification of public land mobile network.

15. The system according to claim 7, wherein the S1 SETUP REQUEST message carries the following information:

a message type, an e-NodeB identification, and a supported tracking area identity;

the S1 SETUP RESPONSE message further carries the following information;

the message type, and a supported identification of public land mobile network.

16. The system according to claim 8, wherein the S1 SETUP REQUEST message carries the following information:

a message type, an e-NodeB identification, and a supported tracking area identity;

the S1 SETUP RESPONSE message further carries the following information;

the message type, and a supported identification of public land mobile network.

10. A device for establishing connection based on a Long Term Evolution/System Architecture Evolution, LTE/SAE, system, which is used for establishing an S1 connection between an evolved NodeB, e-NodeB, and a Mobility Management Entity, MME, wherein, the device comprises:

a request message sending module, arranged at the e-NodeB side, configured to send an S1 SETUP REQUEST message to the MME, to initialize the establishment of S1 connection; and

a response message sending module, arranged at the MME side, configured to return an S1 SETUP RESPONSE message to the e-NodeB, and carry an MME identification in the S1 SETUP RESPONSE message.
