Problems solved by technology

[0004] The PCID of the relay station may change. When the PCID of the relay station changes, according to the existing process, its subordinate base station needs to initiate the network switching process, search the network again, and reconnect to the original relay station with the PCID change. This process wastes network resources. , the problem of low switching efficiency

Embodiment Construction

[0037] 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 creative efforts fall within the protection scope of the present invention.

[0038] In the LTE system, when a terminal UE (User Equipment) moves from one cell to another, it needs to switch from the original serving eNB to the target eNB where the entering cell is located. Refer to figure 1 , the switching process includes:

[0039] S101: The serving eNB makes a handover decision based on the measurement report and radio resource management information;

[0040] S102: The serving eNB sends a handover request message to the target eNB, and ...

Abstract

A message informing method and device are provided. The method includes: receiving a handover indication message; acquiring indication information and new information from the handover indication message, so as to know the service station is not changed, needing no network handover; according to the new information, updating the content related to the new information. Through the method, handover flow is optimized, handover efficiency is improved, and network resources are saved.

Description

technical field [0001] The invention relates to the technology in the field of wireless communication, in particular to a message notification method and device. Background technique [0002] In order to improve the data throughput of users at the edge of the cell and expand the coverage area of ​​the cell, the 3GPP LTE-ADVANCED system has introduced a relay (Relay Node) node, which includes fixed relays, nomadic relays and mobile relays. . [0003] For the LTE-ADVANCED system, each base station eNB (evolved NodeB) or relay station RN (relay node, relay node) needs a physical cell marking PCID (physical-layer cell ID), which is used to ensure that the respective subordinate terminals UE (User Equipment) downlink synchronization. PCID consists of PSS (primary synchronization signal) and SSS (secondary synchronization signal). There are 504 PCIDs for use in LTE-ADVANCED. In addition, the cell uses the physical cell identifier PCID as the scrambling code of the cell, and th...
