Abstract
A method and system to facilitate mobile relay and group mobility in a wireless network. In one embodiment of the invention the wireless network facilitates a mobile relay station that has logic to switch communication with a first base station to a second base station while maintaining logical communication with its associated mobile station(s). By doing so the handover of the mobile relay station from a source base station to a target base station is transparent to the mobile station(s) that are connected with the mobile relay station in one embodiment of the invention.

Claim
1. A relay node comprising:
first circuitry to:
send a handover request to a source enhanced Node B (eNodeB);
receive a handover command message that is to indicate whether the handover request is accepted;
perform ranging of a target eNodeB in response to an indication of the handover command message that the handover request is accepted;
detach from a first cell of the source eNodeB;
synchronize with a second cell of the target eNodeB;
perform network re-entry with the target eNodeB;
perform data path registration or update with the target eNodeB;
perform a random access procedure with the target NodeB;
receive an uplink allocation and timing advance for the relay node;
perform a Radio Resource Control (RRC) reconfiguration with the target eNodeB;
send a handover confirmation to the target eNodeB;
receive one or more physical (PHY) layer operational parameters of the target eNodeB;
determine if one or more user equipment (UE) is to be updated based on the received one or more PHY layer operational parameters;
update respective PHY configurations of the one or more UE using the received one or more PHY layer operational parameters based on the determination;
establish a control path with an Operations, Administration, and Maintenance (OAM) server to update configuration the relay node; and
perform a RRC reconfiguration for each of the one or more UE; and
second circuitry, coupled with the first circuitry, to maintain logical communication with the one or more UE during the switch of communication with the source eNodeB to the target eNodeB.
2. The relay station of claim 1, wherein the relay node, while in an on-powered state, is operable at least in part with one of Institute of Electrical and Electronics Engineers (IEEE) 802.16m standard, and a 3rd Generation Partnership Project (3GPP) Long Term Evolution standard.
3. One or more non-transitory computer-readable media comprising computing device-executable instructions, wherein the instructions, in response to execution by a relay station, cause the relay station to:
send a handover request to a source enhanced Node B (eNodeB);
receive a handover command message that is to indicate whether the handover request is accepted;
performing ranging of a target eNodeB in response to an indication of the handover command message that the handover request is accepted;
detach from a first cell of the source eNodeB;
synchronize with a second cell of the target eNodeB;
perform network re-entry with the target eNodeB;
perform data path registration or update with the target eNodeB;
perform a random access procedure with the target eNodeB;
receive an uplink allocation and timing advance for the relay station;
perform a Radio Resource Control (RRC) reconfiguration with the target eNodeB;
send a handover confirmation to the target eNodeB;
receive one or more physical (PHY) layer operational parameters of the target eNodeB;
determine if one or more user equipment (UE) associated with the relay station is to be updated based on the received one or more PHY layer operational parameters;
update respective PHY configurations of the one or more UE using the received one or more PHY layer operational parameters based on the determination;
establish a control path with an Operations, Administration, and Maintenance (OAM) server to update configuration of the relay station;
perform an RRC reconfiguration for each of the one or more UE; and
maintain logical communication with the one or more UE during the switch of communication with the source eNodeB to the target eNodeB.
4. The one or more non-transitory computer-readable media of claim 3, wherein the instructions are compliant at least in part with one of Institute of Electrical and Electronics Engineers (IEEE) 802.16m standard, and a 3rd Generation Partnership Project (3GPP) Long Term Evolution standard.
