Problems solved by technology

[0003] The existing 5G voice fallback devices and methods have certain defects: when the terminal resides on the NR network and needs to perform voice services, the device only selects the EPC FB fallback cell based on the measured signal strength of the LTE cell. If there are problems such as congestion and alarms in the incoming cell, the voice call will fail

Abstract

The invention discloses a voice fallback method and device, and the method comprises the steps: collecting user signaling information in response to a voice service request from terminal equipment, and obtaining a candidate fallback cell set according to a collection result; for each candidate fallback cell contained in the candidate fallback cell set, calculating cell state data of the candidate fallback cell; selecting a target fallback cell from the candidate fallback cell set according to the cell state data of each candidate fallback cell; and sending a fallback response message including the target fallback cell to the terminal device, so that the terminal device falls back to the target fallback cell to perform a voice service. According to the mode, the target fallback cell can be selected according to the cell state data of each candidate fallback cell, so that the selection of the optimal fallback cell during network voice is further improved, the call connection success rate is improved, the waiting time delay is reduced, and the voice service perception of a user is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a voice fallback method and device. Background technique [0002] The existing 5G NR network construction is mainly carried out through the combination of NSA (non-independent networking) and SA (independent networking). There is currently no voice service in the NSA area, and VoNR service cannot be performed. It needs to fall back to the LTE network for VoLTE, so as to realize Voice service (that is, EPC FB), and when the current LTE cell network status cannot meet the voice VoLTE, eNODEB issues a handover command to switch to the 2G network through ESRVCC for voice service in the circuit domain. When the terminal resides on the NR network and needs to initiate a voice service, the terminal performs measurement according to the issued LTE frequency point information, selects the optimal cell to access and initiates VoLTE according to the measurement result, and the terminal...
