Abstract

Disclosed are a method, a device, and a system for the acquisition of control node information. In embodiments of the present invention, on the basis of information transmitted by a base station, a relay node acquires control node information on user terminal access attached in the information acquired, thereby allowing a relay node in a system placed after the introducing relay node to be informed of the control node information on user terminal access.

Claims

1. A method for acquisition of control node information, comprises:

receiving the messages sent by base station and acquiring the control node information on user terminal access attached in the information acquired.

2. The method as claimed in claim 1, wherein receiving the messages sent by base station, including:

receiving S1 message sent by the base station, which comprises any of the following ones;

initial context setup request message, user terminal context modification request message, handover request message and path switch request acknowledge message.

3. The method as claimed in claim 1, wherein receiving the messages sent by base station, including:

receiving the predefined S1 or X2 message for carrying control node information on user terminal access.

4. The method as claimed in claim 1, further comprising:

judging the handover type and/or addressing control node of the user terminal according to the control node information on user terminal access.

5. A relay node, is characterized in that which comprises:

a receiving unit, is used for receiving messages sent by base station;

an acquisition unit, is used for acquiring control node information on user terminal access attached in the information acquired.

6. The relay node as claimed in claim 5, wherein the receiving unit is also used for:

receiving S1 message sent by base station, which comprises any of the following ones;

initial context setup request message, user terminal context modification request message, handover request message and path switch request acknowledge message.

7. The relay node as claimed in claim 5, wherein the receiving unit is also used for:

receiving the predefined S1 or X2 message carrying control node information on user terminal access.

8. The relay node as claim in claim 5 further comprising:

processing unit, is used used for judging the handover type and/or addressing control node of the user terminal according to control node information on user terminal access.

9. A system for acquiring control node information further comprising:

a base station, is used for sending messages carrying the control node information on user terminal access;

a relay node, is used for receiving messages carrying the control node information on user terminal access and acquiring the control node information on user terminal access attached in the information acquired.

10. The system as claimed in claim 9, wherein the base station comprises:

a sending unit, is used for sending messages carrying the control node information on user terminal access to relay nodes.

11. The system as claimed in claim 10, wherein the base station further comprises:

a receiving unit, is used for receiving S1 message sent to base station by mobility management entity, which comprises any of the following ones;

initial context setup request message, user terminal context modification request message, handover request message and path switch request acknowledge message.

12. The system as claimed in claim 11, wherein the sending unit is also used for:

sending S1 message to relay node, which comprises any of the following ones;

initial context setup request message, user terminal context modification request message, handover request message and path switch request acknowledge message.

13. The system as claimed in claim 11, wherein the sending unit is also used for:

sending the predefined S1 or X2 message for carrying control node information on user terminal access to relay node.

14. A method for acquiring control node information comprising:

sending the message carrying the control node information on user terminal access to the base station.

15. The method as claimed in claim 14, wherein the message refers to S1 message, which comprises any of the following ones:

initial context setup request message, user terminal context modification request message, handover request message and path switch request acknowledge message.

16. A mobility management entity comprising:

a sending unit for sending the message carrying the control node information on user terminal access to the base station.

17. The mobility management entity as claimed in claim 16, is wherein the message is S1 message, which comprises any of the following ones:

initial context setup request message, user terminal context modification request message, handover request message and path switch request acknowledge message.

18. A system for acquiring control node information comprising:

a mobility management entity for sending the message carrying the control node information on user terminal access to the base station;

a base station for receiving the message carrying the control node information on user terminal access sent by mobility management entities, acquiring the control node information on user terminal access attached in the information acquired and sending such information to relay nodes;

a relay node for receiving the messages carrying the control node information on user terminal access sent by the base station and acquiring the control node information on user terminal access attached in the information acquired.
