Method and system for mobile relay enablement
A method and network element for managing a relay node that is moving relative to a source network node, the method sending a handover request from a source network node to a target network node to prepare the handover at the target network node; sending a handover command from the source network node to the relay node without waiting for an acknowledgement of the handover request from the target network node; and detaching the relay node from the source network node.
1. A method for managing a relay node that is moving relative to a source network node, the method comprising:
storing information of a target network node at the source network node;
receiving, at the source network node, a measurement report from the relay node;
sending a handover request from a source network node to the target network node to prepare the handover at the target network node;
sending a handover command and the stored information from the source network node to the relay node without waiting for an acknowledgement of the handover request from the target network node; and
detaching the relay node from the source network node.
2. The method of claim 1 , wherein the stored information allows the relay node to access the target network node.
3. The method of claim 1 wherein the information of the target network node includes radio resource information.
4. The method of claim 3 wherein the radio resource information further includes random access channel information.
5. The method of claim 1 wherein the information of the target network node includes a security configuration.
6. The method of claim 1 wherein the information of the target network node includes an ID allocated to the relay node by the target network node.
7. A source network node configured for managing a relay node that is moving relative to the source network node, the source network node comprising:
a processor; and
a communications subsystem,
wherein the processor and communications subsystem cooperate to:
store information of a target network node;
receive a measurement report from the relay node;
send a handover request from the source network node to the target network node to prepare the handover at the target network node;
send a handover command and the stored information from the source network node to the relay node without waiting for an acknowledgement of the handover request from the target network node;
detach the relay node from the source network node.
8. The source network node of claim 7 , wherein the stored information allows the relay node to access the target network node.
9. The source network node of claim 7 wherein the information of the target network node includes radio resource information.
10. The source network node of claim 9 wherein the radio resource information further includes random access channel information.
11. The source network node of claim 7 wherein the information of the target network node includes a security configuration.
12. The source network node of claim 7 wherein the information of the target network node includes an ID allocated to the relay node by the target network node.
