Problems solved by technology

For the MT in the CSFB process, since the occurrence of various abnormal situations will probabilistically lead to the failure of the CSFB process, resulting in the failure to connect the phone, how to effectively detect the fallback result of CSFB in abnormal scenarios is particularly necessary

Embodiment Construction

[0042] 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.

[0043] 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.

[0044] 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 and searches for a suitable GSM cell / WCDMA cell under the guidance of the LTE network Access; 3) The UE reads the system broadcast message of the GSM cell / WCDMA cell and establishes a voice call.

[0045] As the...

Abstract

Disclosed in the present invention are a CSFB fallback result detection method and apparatus, and a computer readable storage medium. The method comprises: controlling the noise of a GSM network to exceed a preset threshold, such that a UE is in a state in which CSFB fallback to a first cell of a Global System for Mobile Communications GSM network fails; the UE is a UE that triggers CSFB processing when returning to a Long Term Evolution LTE network from the first cell of the GSM network; detecting whether the UE can initiate an access request to a second cell of a time division synchronous code division multiple access network TD-SCDMA network within a preset time; if the UE can initiate an access request to the second cell of the TD-SCDMA network within a preset time, detecting the voice call state of the UE and, on the basis of the voice call state, determining whether the CSFB fallback is successful.

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 computer storage medium. Background technique [0002] Since the wireless communication of Long Term Evolution (LTE, Long Term Evolution) and 2G / 3G dual-mode UE is a single radio mode (Signal-radio mode), therefore, a dual-mode or multi-mode UE with LTE and 2G / 3G access capabilities, When using LTE access, 2G / 3G circuit domain service signals cannot be transmitted. In order to enable UE (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 Switching) services of 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 receiver of the c...
