Embodiment Construction

[0028] The radio access network information management (RIM, RAN Information Management) process is used for the evolution of the universal mobile communication system terrestrial radio access network (E-UTRAN), UTRAN, and radio access for the GSM / EDGE radio access network (GERAN) network Network (RAN) nodes exchange information through the core network; among them, the full English name of GSM is Global System of Mobile communication, and the Chinese name is Global Mobile Communication System; the full English name of EDGE is Enhanced Data Rate for GSM Evolution, and the Chinese name is Enhanced Data Rate for GSM Evolution. Data rate GSM evolution technology. In the present invention, the RAN node that requests information is called a controlling node, and the RAN node that provides information is called a serving node, and RAN nodes associated with RIM applications can be mutually controlling nodes or serving nodes. The RAN node encapsulates the information in the RIM contai...

Abstract

The invention provides a method and a system for acquiring neighbor cell information. The method comprises the following steps that: an ENB (Evolved Node B) sends a request message for acquiring the neighbor cell information to a service node according to basic neighbor cell information acquired in an ANR (Automatic Neighbor Relation) measuring process; and the ENB receives a responding message responded by the service node to update the neighbor cell information. The ENB can acquire related information of a neighbor cell through sending the request message to the service node so that the ENB can select a suitable moving manner and a target cell when UE (User Equipment) moves according to supporting capabilities of each neighbor cell on PSHO (Packet Service Handover), VOIP (Voice Over Internet Protocol), DTM (Dual Transfer Mode), HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access) and the like, so that the use experience of a user and the whole performance of the system are improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for acquiring neighboring cell information. Background technique [0002] One of the basic functions of the cellular mobile communication system is to ensure the service continuity of mobile users, and the implementation of mobility management depends on the correct and complete neighbor cell relationship. In order to correctly and completely configure the neighbor relationship of the cell, in the Long Term Evolution (LTE, Long Term Evolution) system, an automatic neighbor relation (ANR, Automatic Neighbor Relation) function is proposed to maintain the neighbor list. The addition of the ANR function to the neighbor cell relationship is that the evolved node (ENB, Evolved Node B) detects the measurement report message reported by the UE to find a new neighbor cell, and requires the UE to detect and report the neighbor cell through the radio resourc...
