Method and system for mobile relay enablement
A method and relay node for managing a plurality of relay nodes that is moving relative to a source network node, the method comprising: selecting a lead node; connecting the plurality of relay nodes to the lead node; and transmitting a signal to manage mobility of the plurality of relay nodes from the lead node to a network node.
1. A method for managing a plurality of relay nodes that is moving relative to a source network node, the method comprising:
selecting a lead node;
connecting the plurality of relay nodes to the lead node; and
transmitting a signal to manage mobility of the plurality of relay nodes from the lead node to a network node;
wherein the signal to manage mobility comprises at least one of:
a measurement report;
a request to initiate a handover;
a random access signal;
an RRC connection signal; receiving at a relay node selecting from the plurality of relay nodes, parameters of a target network node from the source node; initiating an attachment of the relay node to the target network node; and detaching the relay node from the source node.
2. The method of claim 1 , wherein the lead node is a relay node with user equipments (UEs) attached to it.
3. The method of claim 1 , wherein the lead node is a dedicated relay node without user equipments (UEs) attached to it.
4. The method of claim 1 , wherein the plurality of relay nodes are wirelessly connected to the lead node.
5. The method of claim 1 , wherein the plurality of relay nodes are connected to the lead node via a wire.
6. The method of claim 1 , wherein the network node is a source network node.
7. The method of claim 1 , wherein the network node is a target network node.
8. A first relay node, comprising:
a processor; and
a communications subsystem,
wherein the processor and communications subsystem cooperate to:
connect to one or more secondary relay nodes; and
transmit a signal from the first relay node to a network node to manage mobility of the one or more secondary relay nodes;
wherein the signal to manage mobility comprises at least one of:
a measurement report;
a request to initiate a handover;
a random access signal;
an RRC connection signal; receive, at the first relay node, parameters of a target network node from a source network node; initiate an attachment of the first relay node to the target network node; and detach the first relay node from the source network node.
9. The first relay node of claim 8 , wherein the first relay node has user equipments (UEs) attached to it.
10. The first relay node of claim 8 , wherein the first relay node is a dedicated lead relay node without user equipments (UEs) attached to it.
11. The first relay node of claim 8 , wherein the one or more secondary relay nodes are wirelessly connected to the first relay node.
12. The first relay node of claim 8 , wherein the one or more secondary relay nodes are connected to the first relay node via a wire.
13. The first relay node of claim 8 , wherein the network node is the source network node.
14. The first relay node of claim 8 , wherein the network node is a target network node.
