Method for improving mobility robustness, system and equipment thereof

Abstract

An embodiment of the invention relates to the wireless communication technology field and especially relates to a method for improving mobility robustness, a system and equipment thereof. The invention aims at improving determination accuracy of the mobility robustness in a networking environment of a Macro base station and a Pico base station under a Hetnet scene. In the embodiment of the invention, first network side equipment sends a finally obtained wireless signal quality parameter value of a cell to second network side equipment containing the cell whose parameter is not set up correctly, wherein the value is obtained before user equipment generates failure connection. The second network side equipment determines the decision signal quality value of the corresponding cell according to the wireless signal quality parameter value of the cell and then determines a reason of generation of the failure connection according to the decision signal quality value of the cell. The multilayer coating condition is considered in the Hetnet scene, determination accuracy of the mobility robustness in the networking environment of the Macro base station and the Pico can be improved.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method, system and equipment for improving mobile robustness. Background technique [0002] Reducing the complexity of operation management and reducing the cost of operation and maintenance are urgent requirements of communication operators. In the next-generation network, it is hoped that by introducing a network self-organization mechanism, manual participation in network planning and operation and maintenance is reduced, and network construction and operation costs are reduced. It is in this context that the SON (Self Organizing Networks) feature of the E-UTRA (Evolved Universal Terrestrial Radio Access) system is used as the 3GPP (3rd Generation Partnership Project, the third generation of mobile Communication Standardization Organization) a work topic for research. SON technology includes self-configuration, self-optimization and self-healing. Self-op...

Problems solved by technology

[0013] To sum up, currently, in the mobile robustness solution, only the common macro base station single-layer coverage method is considered, so that the accuracy of mobile robustness judgment in the Macro and Pico networking environment in the Hetnet scenario is relatively low
