Problems solved by technology

[0012] However, there are very large redundant message interaction scenarios in the above message interaction: such as image 3 As shown, when the neighboring cell information of base station B changes, it will send a configuration update message to base station A and base station C. After receiving the configuration update message, base station A will send a configuration update message to its neighboring base stations, so it will send Send message 2; similarly, C will also send message 4 to B, but these two messages, namely message 2 and message 4 are redundant messages. For base station B, the information trigger source of this change comes from itself, so this information is for Judging that PCI conflict detection has no contribution and is redundant information
When the base station topology is large, redundant message flows are exchanged between base stations, which increases the load on the network

Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0034] In order to achieve the purpose of the present invention, the present invention discloses a configuration update method, which includes the following steps: when the cell information under the base station B changes, the base station B sends an X2 configuration update message to the adjacent base station A with an X2 connection After the adjacent base station A receives the X2 configuration update message, after updating the cell information of the local adjacent base station B, it sends a configuration update response message to t...

Abstract

The embodiment of the invention provides an update configuration method, which comprises the following steps: when cell information under a base station B changes, and the base station B sends an X2 configuration upgrade message to an adjacent base station A with an X2 connection existed therein; and after receiving the X2 configuration upgrade message and upgrading the cell information of the locally adjacent base station B, the adjacent base station A sends the configuration upgrade response message to the base station B, the change of the cell information in the base station B can trigger a new X2 configuration upgrade message of the adjacent base station A, and the adjacent base station A sends the new X2 configuration upgrade message to other adjacent base stations except for the base station B. By adopting the scheme provided by the invention, a source base station for judging and generating the X2 configuration upgrade message via the base stations sends the X2 configuration upgrade message to the adjacent base stations without sending redundant information of the configuration upgrade to the source base station, so that the redundant information can be effectively reduced, the efficiency of a PCI (Physical Cell Identifier) collision detection algorithm is improved, and the system property is enhanced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a configuration update method and equipment. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project) is committed to the evolution of LTE (Long Term Evolution, long-term evolution) system as a 3G system. The goal is to develop 3GPP wireless access technology towards Evolution for high data rate, low latency and optimized packet data applications. [0003] In the LTE system, the base station and the base station can be directly interconnected through the X2 connection. The base stations exchange information such as cells and neighboring cells under the base station according to certain trigger conditions, which are cell handover, PCI (Physical Cell Identifier, physical cell identifier ) detection and reselection functions to prov...
