Embodiment Construction

[0041] 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 embodiments of the present invention.

[0042] Under normal circumstances, a terminal with CSFB function can search for LTE network when it is turned on, complete LTE / 2G network joint registration, and can make voice calls and calls.

[0043] The CSFB process includes three stages: 1) UE initiates a call on the LTE network (corresponding to MO), or receives paging (corresponding to MT); 2) UE falls back under the guidance of LTE network and searches for a suitable GSM cell / WCDMA cell to perform Access; 3) The UE reads the system broadcast message of the GSM cell / WCDMA cell and establishes a voice call.

Abstract

Embodiments of the present invention disclose a method for detecting the fallback result of circuit domain fallback CSFB, which includes: during the CSFB process based on the instruction information instructing the terminal to adopt the preset CSFB optimization scheme to perform voice services, detecting that the terminal is in the specified third The voice call status of the second target wideband code division multiple access WCDMA cell; the voice call of the terminal in the designated second target WCDMA cell is when the signal in the designated first target WCDMA cell becomes weak, causing the signal in the first target WCDMA cell to weaken. It is triggered after the voice call establishment in the circuit-switched CS domain of the WCDMA cell fails; based on the detected voice call status, it is judged whether the CSFB fallback is successful. Embodiments of the present invention also disclose a circuit domain fallback CSFB fallback result detection device and a storage medium.

Description

technical field [0001] The present invention relates to the technical field of CSFB (Circuit Switched Fallback), in particular to a CSFB fallback result detection method and device, and a storage medium. Background technique [0002] Since the wireless communication of Long Term Evolution (LTE, Long Term Evolution) and 2G / 3G dual-mode terminals is a single wireless mode (Signal-radio mode), therefore, dual-mode or multi-mode terminals with LTE and 2G / 3G access capabilities, When using LTE access, 2G / 3G circuit domain service signals cannot be transmitted. In order to enable a terminal (UE, User Equipment) to perform circuit domain (CS, Circuit Switched) services such as voice when accessing or camping on LTE, and to perform packet domain (PS, Packet Switched) services of the UE under LTE access ) The business is processed correctly, resulting in CSFB technology. [0003] In the CSFB process, the originator of the call is called the caller (MO, Mobile Origination), and the ...
