Embodiment Construction

[0098]In order to avoid the problem that the donor base station selects a target cell that cannot be accessed by the relay node for the relay node, thereby causing handover failure, the embodiment of the present invention provides a method for configuring base station information, interacting with base station information, and selecting a target cell. In the operation and maintenance (OAM) equipment, the donor (donor) attribute information of the base station (including the donor base station) is configured to the corresponding base station, and the base station sends the obtained donor attribute information to other base stations adjacent to the base station (including the donor base station) ; The donor base station can select the target cell for the relay node to perform cell handover in the following two ways: first, the donor base station determines the donor cell that the relay node is allowed to access according to the received donor attribute information, and the informa...

Abstract

The embodiment of the invention discloses a method, system and equipment of selecting a target cell, which relates to the technical field of wireless communication and is used for solving the problem that a donor base station selects the target cell to which the relay node is not allowed to access for the relay node, so as to cause failed switch. In the invention, operation and maintenance (OAM) equipment allocates the donor attribute information of the base station to the base station; the base station sends the obtained donor attribute information to other base stations adjacent to the basestation; and the donor base station determines a donor cell to which the relay node is allowed to access according to the received donor attribute information and sends the information of the determined donor cell to the relay node, the relay node only reports the measurement information of the donor cell, and the donor base station selects the target cell performing cell switch for the relay node according to the measurement information reported by the relay node. According to the invention, the problem that the donor base station selects the target cell to which the relay node is not allowed to access for the relay node so as to cause the failed switch is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for selecting a target cell. Background technique [0002] In order to improve the quality of mobile communication services in high-speed mobile scenarios, a mobile relay (Relay) technology is introduced. [0003] The network architecture of the mobile relay is similar to that of the fixed relay, such as figure 1 As shown, the mobile relay node is connected to the cell under the jurisdiction of its home base station through a wireless interface, and then connected to the core network through a wired network. The base station is called a donor base station (DeNB) of the mobile relay node, and the cell is called a donor cell (Donor Cell) of the mobile relay node. [0004] figure 1 There are three wireless interfaces in China: the Un interface between the mobile relay node and the donor base station; the Uu interface between t...
