Abstract

An apparatus and a method of providing a voice call service are provided. The method includes maintaining cell lists of unreliable voice over long term evolution (VoLTE) cells, wherein the cell lists include a first cell list and a second cell list; and when receiving an unreliable VoLTE service from a modem, adding a cell to the first cell list. This can improve voice quality and reliability in a poor LTE coverage.

Description

technical field [0001] The present disclosure relates to the field of communication systems, and more particularly, to a device and method for providing voice call services that can provide good communication performance and high reliability. Background technique [0002] A user equipment may enter poor long-term evolution (LTE) coverage, where the reference signal received power (RSRP) of the serving cell is good, but the signal-to-noise ratio (SNR) of the serving cell is poor. According to the 3rd Generation Partnership Project (3GPP) specification, user equipment cannot trigger Inter-Radio Access Technology (IRAT) measurement reports to assist the network in handing over the user equipment to a Global System for Mobile Communications (GSM) cell. As a result, ongoing Voice over Long Term Evolution (VoLTE) calls may be affected or interrupted. [0003] The problems in this area are as follows: [0004] 1. Poor VoLTE call quality (packet loss) due to low SNR (poor network ...
