Problems solved by technology

[0002] With the development of communication technology, the communication industry has put forward high system capacity requirements for IMT-Advanced (Advanced International Mobile Telecommunications) systems, but large-bandwidth spectrum sufficient to support high capacity may only be found in higher frequency bands. The path loss and penetration loss of the frequency band are relatively large, and it is difficult to achieve good coverage

Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] After introducing the relay station into the existing system, the access link of the UE-eNB is changed from the original single-hop to two-hop or multi-hop, and the interface of the RN-eNB is a newly defined Un interface. Currently, LTE-A technology does not involve specific technical details related to relay handover, including handover decision entity, handover decision basis, handover process, etc. If the existing LTE handover mechanism is used, that...

Abstract

The embodiment of the invention discloses a switching method, an evolved Node B (eNodeB) and a home gateway and belongs to the technical field of communication. The method comprises: the eNodeB determines that user equipment (UE) is switched to the eNodeB or a second subordinate relay station of the eNodeB from a first subordinate relay station of the eNodeB; and the eNodeB sends a UE context release command to the first relay station under the condition of sending no switching notification to core network equipment. According to the technical scheme, in the UE switching process, the terminal switching flow of a relay network is simplified.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a switching method, a base station and a home gateway. Background technique [0002] With the development of communication technology, the communication industry has put forward high system capacity requirements for IMT-Advanced (Advanced International Mobile Telecommunications) systems, but large-bandwidth spectrum sufficient to support high capacity may only be found in higher frequency bands. The path loss and penetration loss of the frequency band are relatively large, and it is difficult to achieve good coverage. In order to meet the capacity requirement of IMT-Advanced in LTE-A (LTE-Advance, evolution of LTE), Relay (relay) technology may be used to improve system capacity and coverage. [0003] In the existing LTE (Long Term Evolution, long-term evolution) system, the eNodeB (evolved base station) interacts with the MME / S-GW through the S1 interface, and the S1 inte...
