Abstract
A method and apparatus for performing load re-balancing for the dedicated core network in a wireless communication system is provided. An evolved NodeB (eNB) which supports a dedicated core network receives a mobility management entity group identity (MMEGI) of an MME pool, corresponding to the dedicated core network, from a UE which is attached to a first MME of the MME pool. The eNB redirects the UE to a second MME of the MME pool by using the MMEGI of the MME pool.
Claims4
A method performed by an evolved NodeB (eNB) supporting a dedicated core network in a wireless communication system, the method comprising:
- receiving, by the eNB, from a first mobility management entity (MME) an S1 user equipment (UE) context release command message including a cause value, which indicates load re-balancing for the dedicated core network, wherein the first MME is included in a dedicated MME pool;
- transmitting, by the eNB, a radio resource control (RRC) connection release message including the cause value to a UE, wherein the RRC connection release message indicates that the eNB supports the dedicated core network functionality;
- receiving, by the eNB, from the UE a RRC connection setup complete message including an MME group identity (MMEGI) indicating the dedicated MME pool;
- selecting, by the eNB, a second MME among plurality of MMEs included in the dedicated MME pool;
- and
- redirecting, by the eNB, the UE to the second MME, by transmitting a S1 initial UE message to the second MME,
- wherein the dedicated MME pool is a specific group of the dedicated core network for a specific subscriber.
An evolved NodeB (eNB) comprising:
- a memory;
- a transceiver;
- and
- a processor, coupled to the memory and the transceiver, that:
- controls the transceiver to receive from a first mobility management entity (MME) an S1 user equipment (UE) context release command message including a cause value, which indicates load re-balancing for a dedicated core network, wherein the first MME is included in a dedicated MME pool,
- controls the transceiver to transmit a radio resource control (RRC) connection release message including the cause value to a UE, wherein the RRC connection release message indicates that the eNB supports the dedicated core network functionality,
- controls the transceiver to receive a RRC connection setup complete message including an MME group identity (MMEGI) indicating the dedicated MME pool from the UE,
- selects a second MME among plurality of MMEs included in the dedicated MME pool, and
- redirects the UE to the second MME, by transmitting a S1 initial UE message to the second MME,
- wherein the dedicated MME pool is a specific group of the dedicated core network for a specific subscriber.
