METHOD FOR REGISTERING ON VOICE-OVER-LTE NETWORK, DEVICE AND TERMINAL, AND COMPUTER STORAGE MEDIUM

ONEPLUS TECHNOLOGY (SHENZ...

1. A method for registration on a Voice over Long Term Evolution (VoLTE) network, comprising:detecting a VoLTE card to acquire an Integrate Circuit Card Identity (ICCID) number of the VoLTE card;
acquiring a first Issuer Identification Number (IIN) of the VoLTE card and a first length of the first IIN from the ICCID number;
acquiring a modem software configuration (MBN) list of a terminal to obtain a second IIN of each MBN file in the MBN list and a second length of the second IIN;
determining whether the first length exceeds a preset value or not;
in the case that the first length exceeds the preset value, sequentially comparing the second IINs with the first IIN until a second IIN that is identical to first N characters of the first IIN is found, a length of the N characters being the same as the second length; and
loading the MBN file corresponding to the found second IIN to register on the VoLTE network.
