Method and device for reducing CSFB delay

Abstract

The embodiment of the invention discloses a method and a device for reducing CSFB delay, which relate to the technical field of communication and can solve a problem that methods for reducing CSFB delay are relatively single. The method provided by the embodiment comprises the following steps of: acquiring target data, wherein the target data comprises RNC call record of a wireless side and structured event record of a core network; determining the first delay according to the RNC call record and the structured event record; obtaining a first adjustment scheme corresponding to the first delay, wherein the first adjustment scheme comprises a first to-be-adjusted parameter which is in the wireless side or the core network and corresponds to each delay parameter in the first delay, and adjustment direction of the first to-be-adjusted parameter; and adjusting the first to-be-adjusted parameter according to the first delay and the first adjustment scheme so as to reduce the CSFB delay. The method and the device provided by the invention are suitable for optimizing the CSFB delay.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for reducing CSFB time delay. Background technique [0002] With the development of communication technology, especially the popularization of LTE (Long Term Evolution, Long Term Evolution) network, most services can be provided by the LTE network. After the terminal accesses the FDD (Frequency Division Duplex, Frequency Division Duplex)-LTE network, if the voice service needs to be interrupted, it needs to perform CSFB (Circuit Switched Fall Back, circuit domain fallback), that is, fall back from the FDD-LTE network to 2G (The2ndGeneration, The second generation mobile communication technology) network and access to the 2G network, or fall back to the 3G (The3rdGeneration, third generation mobile communication technology) network and access to the 3G network. [0003] At present, in order to reduce the delay of switching from the FDD-LTE netwo...

Problems solved by technology

[0004] However, the above method can only reduce the CSFB delay in the process of falling back from the FDD-LTE network to the 2G network or 3G network. Therefore, in the CSFB process, the method for reducing the CSFB delay is relatively simple, that is, only It can reduce CSFB delay in the process of falling back from FDD-LTE network to 2G network or 3G network, and reduce the reduction of CSFB delay
