Abstract:
1. A method of transmitting a bearer resource request message from a user equipment (UE) to a mobility management entity (MME) for setting up an evolved packet system (EPS) bearer in a long term evolution (LTE) network, the method comprising: receiving the bearer resource request message at the mobile management entity from the UE, wherein the bearer resource request message is corresponding to the UE's original bearer resource request, wherein the bearer resource request message is propagated to the mobile management entity by a plurality of relay nodes, each of the plurality of relay nodes through a path to the mobile management entity being configured to attach a tag comprising a relay node identifier to the bearer resource request message; inspecting the received bearer resource request message by the mobile management entity, wherein inspecting the received bearer resource request message comprises determining, from the attached tags, the relay node identifier for each of the plurality of relay nodes involved in the propagation of the original bearer resource request message to the mobile management entity; creating a new bearer resource request for the plurality of relay nodes, wherein the plurality of relay nodes are identified by the determined relay node identifications; multicasting the created new bearer resource request message to the plurality of relay nodes; receiving responses from each of the plurality of relay nodes for the multicasted new bearer resource request message; and collating the responses received from the plurality of relay nodes; admitting the user equipment to the long term evolution (LTE) network based on the collated responses; and, forwarding a response for the original bearer resource request as an S1 application part (S1-AP) message to the UE and the plurality of relay nodes.
