A csfb fallback frequency point optimization method and server

Abstract

Embodiments of the present invention provide a CSFB fallback frequency optimization method and server. The method includes: obtaining GSM broadcast control channel frequency point information within the first preset time period reported by the terminal, using preset rules to obtain a preset number of target broadcast control channel frequency points, and forming a target CSFB fallback frequency point group; store the target CSFB fallback frequency point group in the CSFB fallback optimal frequency point group database, so that the OMC platform can periodically obtain and apply the target CSFB fallback frequency point group. The server is used to execute the method. In the embodiment of the present invention, according to the GSM broadcast control channel frequency point information, the target CSFB fallback frequency point group is obtained using preset rules and written into the CSFB fallback optimal frequency point group database, and the server logs in to the OMC After the platform, the target CSFB fallback frequency point group in the CSFB fallback optimal frequency point group database is applied, thereby improving the accuracy and efficiency of the CSFB fallback frequency point.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a CSFB fallback frequency point optimization method and server. Background technique [0002] Voice service based on Circuit Switched Fallback (CSFB) is a voice service that utilizes the existing GU (GSM / UMTS) network without introducing the IP Multimedia Subsystem (IMS) , a voice solution for voice calls. In this solution, when a user performs a voice service, the Evolved Packet System (EPS) network instructs the user to fall back to the target GSM / UMTS circuit domain (CS) network before initiating a voice call. [0003] The LTE terminal realizes TA (Tracking Area under LTE) / LA (GSM Location Area) joint update under the LTE network, and realizes registration on the MME of LTE and the MSC of GSM at the same time. For voice paging messages, use the GSM frequency specified in the RRC connection release (RRC connection release) of the LTE dow...

Problems solved by technology

[0004] In the prior art, the fallback BCCH frequency point group carried in the RRC connection release issued by the network side is selected by the network optimization personnel according to the BCCH frequency point parameters of the surrounding GSM cells and the geographical environment, and manually configured in the background in the LTE cell; or directly packaged All GSM network BCCH frequency point groups in this city are sorted out and configured with LTE cell fallback frequency point groups uniformly, which leads to the problems of low accuracy of the selected fallback frequency point group and cumbersome configuration process
