Information change notifying method and base station configuration updating information setting method and device

Abstract

The invention provides a method for notifying a service cell and a neighbor cell of information change. The method comprises the step that a first base station sends the base station configuration updating information to a neighboring second base station, wherein the base station configuration updating information comprises changed service cell information in the first base station, added neighbor cell information, modified neighbor cell information and / or deleted neighbor cell information; and in the base station configuration updating information, the service cell information in the information field corresponding service cell modification comprise neighbor cell addition, neighbor cell modification and neighbor cell deletion information items which correspond to the added neighbor cell information, the modified neighbor cell information and the deleted neighbor cell information respectively. By the method and the device, the change cell information which is clear and low in data transmission amount can be provided, and the quick and convenient organization and transmission of the change information are realized.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for notifying serving cell and neighbor cell of information change. Background technique [0002] In a long-term evolution (LTE) system, a physical-layer cell identifier (Physical-layer Cell Identifier, PCI) adopts a manner of self-configuration of a base station. However, after the PCI configuration is completed and the base station starts running, the surrounding network may change at any time, for example, a new base station is added, or the base station changes the PCI value of the cell parameter. These changes may cause PCI conflicts or confusion. [0003] At present, a method of notifying neighboring eNB serving cells and neighbor cell information changes by means of X2 interface base station (eNB) configuration update messages during the operation of the base station is proposed. The method flow can be referred to figure 1 . As shown in the figure, wh...

Problems solved by technology

[0004] However, using this information notification method, there are certain troubles for both the receiver and the sender of the message.

For example, when the serving cell or neighboring cell information changes, the sending eNB needs to organize the relevant serving cell and all the corresponding current neighboring cell information, the transmission message is relatively large, and the message organization is relatively cumbersome

The receiver's eNB can understand the changes in the addition and deletion of the serving cell of the sender's neighboring eNB, but it is not clear about the changes in its serving cell and neighboring cell information

[0005] In addition, since only changed information (including changed serving cell information, newly added, deleted or modified neighbor cell information) is necessary to re-examine the conflict and confusion regardless of the serving cell or neighboring cell information of the neighboring eNB, the receiver It is necessary to compare and judge all the received information and the information stored locally one by one, so as to know the change of the corresponding eNB serving cell information and / or the addition, deletion, and modification of neighboring cells, so the operation is complicated and the efficiency is low
