Bearer signaling management method

A method for bearer management signalling in a communication network, the method comprising:

• receiving a union of resource (UR) Request message at a donor base station (DeNB) of the communication network, wherein receiving the UR Request message comprises a user equipment non-access stratum (UE NAS) message, and the relay node identifiers (RN_IDs) added by Relay Nodes;
• transporting, by the DeNB, the UR Request message to a managing entity of user equipment (UE) within an Evolved Packet Core (EPC) network of the communication network, wherein the managing entity of UE are network nodes that manage or administer the UE, and is at least one of a mobility management entity serving the user equipment (MME_UE), a serving gate way, a packet gate way, and a PCRF;
• receiving an Implicit Admission (IA) Response by the DeNB for the transported UR Request, from one of the network nodes of the management entity that does not serve and manage entities in the EPE, wherein receiving the IA Response comprises receiving the IA Response from the MME_UE;
• and
• forwarding the received IA Response to the UE via the relay node, wherein IA Response implicitly informs the UE regarding granted utmost UR request.

A communication network comprising:

• a relay node;
• and
• a donor base station (DeNB) connected to the relay node, wherein the donor base station comprises:
• a receiver for receiving a bearer resource request message at a donor base station (DeNB) of the communication network, wherein receiving the bearer resource request message comprises a user equipment non-access stratum (UE NAS) message, and the relay node identifiers (RN_IDs) added by Relay Nodes to the bearer resource request;
• a transmitter configured to forward the received bearer resource request to a management entity of an evolved packet edge (EPE) node of the communication network;
• and
• wherein the receiver is configured to receive an intersection of admission (IA) response from the management entity of the EPE in response to the bearer resource request,
• wherein the transmitter is configured to forward the received IA response to the UE via the relay node which implicitly informs the UE regarding granted utmost UR request, wherein the relay node is transparent to the UE.
