Implicit signalling method for bearer management

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

• Forming “Union of Resource (UR) Request” message in the Evolved Packet Edge (EPE), wherein EPE includes user equipment (UE) and at least one relay node (RN) and the like;
• Transporting the “UR Request” message from the EPE via Base station to managing entity of relay nodes (RNs) within EPC, wherein ‘managing entity of RNs’ are network nodes that manage or administer RNs like mobility management entity serving the relay node (MME_RN), serving gate way, packet gate way, PCRF, HSS or combination thereof;
• and
• Receiving “Implicit Admission (IA) Response” by the Base station for the transported UR Request, from one of the said management entities within EPC wherein at least one of the said management entities is the mobility management entity not serving/managing the same entities in the EPE.

A bearer management signalling system for relay node in a communication network comprising of;

• A receiver for receiving NAS Message, “IA Response” message;
• A processor for tagging wherein, tagging includes adding user equipment identity (UE_ID) with the said received NAS message, at least in any one of the control plane protocol layers like S1-AP, SCTP, PDCP, RLC, MAC, PHY, preferably over NAS;
• wherein the NAS message is UE NAS message when coupled to UE, and wherein the NAS message is RN NAS message when coupled to UE via another relay node;
• and wherein UE_ID is RN_ID when coupled to UE via another relay node;
• A processor for constructing an RN NAS message by encapsulating the received NAS message along with the said TAG;
• A transmitter for transmitting RN NAS message towards the managing entity via Base station;
• A processor for understanding the received “IA Response” message and ‘NAS message’ from Base station and performing RRC configuration if indicated in the said “IA Response” message;
• A transmitter for transmitting ‘NAS message’, ‘radio bearer configuration message’, “IA Response” to EPE entities;
• and
• A memory that retains instructions for executing functions associated with the receiver, processor/processors, and transmitter and as well as measured or computed data that may be generated during executing such functions.
