Problems solved by technology

This method may cause problems such as loud noise and poor call quality during the call. However, judging from the indicators, the call has been connected and the CSFB has been successfully dropped. Business call perception is poor
[0005] 2) In an outdoor environment, CSFB terminals cannot fall back to a nearby 2G cell
As for the judging method of whether the CSFB is reasonable after the success of the fall, no relevant patents have been found so far.

Embodiment Construction

[0036] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the present invention.

[0037] It should be noted that the success of the CSFB fallback in the optimization process in the embodiment of the present invention mainly refers to the fallback from the 4G network to the 2G network, which is a strategy specified by the mobile operator, and because the coverage of the 2G network is wider; if the 4G network Falling back to the 3G network is to fall back to the 2G network from the 4G network first, and then fall back to the 3G network after the fallback fails. In this way, although the fallback may succeed, it will lead to prolonged network connection delays and affect user...

Abstract

The invention discloses a fallback performance judgment method for circuit switched fallback (CSFB). The method comprises the following steps: screening a first cell list and a second cell list according to an information association table; arranging 4G-2G cell pairs of which CSFB succeeds according to the first cell list and the second cell list, and calculating distances of the 4G-2G cell pairs; and judging whether the distances of the 4G-2G cell pairs under different wireless coverage scenes exceed a preset corresponding threshold value or not, and if so, judging that the CSFB is unreasonable. Meanwhile, the invention also discloses a fallback performance judgment device for the CSFB.

Description

technical field [0001] The present invention relates to fallback performance management technology, in particular to a method and device for judging the fallback performance of CSFB (CircuitSwitched Fallback). Background technique [0002] Currently, voice service solutions supported by the Time Division Long Term Evolution (TD-LTE, Time Division Long Term Evolution) system include: CSFB and single card dual standby. Among them, the single-card dual-standby mode directly uses the 2G / 3G network to provide voice services, while the CSFB mode is when the terminal initiates a voice service, and the evolved packet core network system (EPS, Evolved Packet System) network instructs the terminal to fall back from the LTE network to 2G / 3G network, and then initiate a voice call connection on the 2G / 3G network. [0003] Among them, the CSFB call establishment process includes three stages: the user terminal (UE, User Equipment) initiates a call (calling MO) or receives a page (called...
