Problems solved by technology

[0006] Considering that the list information provided by the base station to the terminal in the related art may lose accuracy and validity over time, and the re-provided list information may contain a large amount of repeated information, resulting in waste of resources and high overhead, this paper is proposed Invention, for this reason, the main purpose of the present invention is to provide an effective update scheme for neighbor cell list information and access list information, so as to solve at least one of the above-mentioned problems existing in related technologies

Embodiment 1

[0069] According to an embodiment of the present invention, a method for updating neighbor list information is provided, figure 2 is a flowchart of a method for updating neighbor cell list information according to an embodiment of the present invention.

[0070] in progress as figure 2 Before the processing shown, first perform the following processing:

[0071]If the current neighbor list information of the terminal is provided by the base station, the base station first needs to generate an update message according to the current neighbor list information (it should be noted that the update message refers to an update message related to the terminal receiving the message), the above The current neighbor list information includes: the neighbor list information carried in the update message sent by the base station in broadcast, multicast, and / or unicast; if the current neighbor list information of the terminal is not provided by the base station or the current neighbor lis...

example 1

[0092] In Example 1, after receiving the update message unicast by the macro base station, the terminal deletes the original neighbor list according to the instruction in the update message, and creates new neighbor list information.

[0093] After the terminal is handed over from macro base station A to macro base station B, macro base station B sends an update message of neighbor cell list information to the terminal, providing a new neighbor cell list for the terminal, wherein the neighbor cell list in the update message includes: terminal A list of searchable adjacent macro base stations, and a list of adjacent femto base stations searchable by the terminal. Usually, this new neighbor list can completely replace the neighbor list obtained by the terminal from the macro base station A. Specifically, the update message of the neighbor cell list obtained by the terminal from the macro base station B may be in the format shown in Table 1 or Table 2, wherein Table 1 and Table 2...

example 2

[0101] Example 2, after the terminal enters the coverage area of ​​a macro base station, the macro base station can send neighbor cell list information to the terminal according to the change of the relative position between the terminal and the femto base station in the coverage area.

[0102] After the terminal enters the coverage area of ​​a macro base station, the macro base station can send the neighbor cell list information to the terminal according to the relative position between the terminal and the femto base station in the coverage area, and the terminal obtains the neighbor cell list from the macro base station or other base stations with the assistance of the macro base station information. Using the acquired list information, the terminal can scan adjacent femto base stations to try to switch to a femto base station that can provide better service quality.

[0103]Specifically, the terminal is free to move within the coverage area of ​​the macro base station. As ...

Abstract

The invention discloses an adjacent area list information and access list information updating method and a terminal and a base station thereof, wherein the adjacent area list information updating method comprises the following steps that: the terminal receiving base station sends the updating information of the adjacent area list information comprising sub-base station information, wherein the updating information carries information of revising the current adjacent area list information to the terminal; and the terminal updates the adjacent area list information stored locally according to the updating information. Through the technical scheme, the invention can effectively reduce the communication overhead between the base station and the terminal, and simultaneously, improve the switching and the accessing performance of the wireless communication system.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a neighbor cell list information, a method for updating access list information, a terminal and a base station. Background technique [0002] At present, in a wireless communication system, a base station (Base Station, BS for short) is a device that provides services for a terminal, and the BS communicates with the terminal through the uplink and downlink, where the downlink (forward) link refers to the connection between the BS and the terminal The uplink (reverse) link refers to the direction from the terminal to the BS. In addition, a plurality of terminals may simultaneously transmit data to the BS through an uplink, and may simultaneously receive data from the BS through a downlink. The wireless communication system can provide wireless coverage for terminals in a certain geographical range through the BS, and in related technologies, the above geographical r...
