Patent ID: 8804667

Claim:
A method for implementing inter-eNB switch, comprising the following steps of: when a user equipment switches from a source-side eNB to a target-side eNB, the target-side eNB, after the switch is completed, sending to a Mobility Management Entity (MME) a PATH SWITCH REQUEST message to indicate that the eNB side has changed; the MME, after completing update of the S-GW, sending to the target-side eNB a PATH SWITCH REQUEST ACKNOWLEDGE message for indicating whether a Serving Gateway(S-GW) has changed or not; if the target-side eNB acquires via the MME that the S-GW has changed, the target-side eNB adding a new routing relation of the S-GW and then updating a General Packet Radio Service(GPRS) Tunnelling Protocol User Plane (GTP-U) entity; and the target-side eNB deleting an old routing relation of the S-GW after successfully completing update of the GTP-U entity.
