Self-configuration self-optimization method, self-configuration self-optimization system, and self-configuration self-optimization device

Abstract

The invention discloses a self-configuration self-optimization method, a self-configuration self-optimization system, and a self-configuration self-optimization device. A base station of a control coverage modification cell is used to notify a second base station of coverage modification information, and the second base station is used to switch multiple preparations, and / or store or update the modification information of the coverage modification cell, and / or store or recover the self-organization MRO state of the modification cell. During a self-organization process of a SAE system, in scenes of cell splitting / merging and cell forming, problems of UE such as failed switching and failed subsequent reconstruction are solved.

Description

technical field [0001] The invention relates to the field of mobile communication systems, in particular to a method, system and device for self-configuration and self-optimization. Background technique [0002] With the development of communication technology, the mobile communication system has developed into a System Architecture Evolution (SAE) system, figure 1 Schematic diagram of the structure of the SAE system provided for the prior art. Such as figure 1 As shown, the system includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 101 and a core network including at least a Mobility Management Entity (MME) 105 and a User Plane Entity (S-GW) 106, and the E-UTRAN 101 is used to connect User equipment (UE) to the core network, and E-UTRAN 101 includes more than one macro base station (eNB) 102 and home base station (HeNB) 103, optionally including home base station gateway (HeNBGW) 104, MME 105 and S - The GW 106 can be integrated into one module, or c...

Problems solved by technology

For example, if cell C is split into cell D and cell E, how does the base station controlling cell C notify the neighboring base station of the status of cell C after the cell splitting? If cell C is placed in the list of deleted cells, the neighboring base station will put The information related to cell C is deleted, so that the adjacent base stations cannot save the parameters related to the movement of cell C, and the self-optimization (MRO, Mobility Robustness Optimization) of cell C cannot be restored when cell C becomes active next time Related parameters

If cell C is not placed in the deleted serving cell information, some information of cell C cannot be released in time even when it is not working, such as physical-layer cell identity (PCI, physical-layer cell identity), etc., which will easily lead to PCI failure. Collision, not conducive to system planning

[0006] Furthermore, in the self-optimization process of the SAE system, the current solution cannot effectively solve the problem of reconstruction failure in the scenarios of cell splitting / merging and cell shaping
