Abstract

The invention provides an MBN updating method and a mobile terminal. The MBN updating method includes the following steps: acquiring current geographical location information of the mobile terminal and a currently-used MBN; judging whether the current geographical location information is matched with the currently-used MBN; when determining that the current geographical location information is notmatched with the currently-used MBN, obtaining a local MBN corresponding to the current geographical location information; and updating the currently-used MBN to the local MBN. According to the technical scheme provided by the invention, the problem that an existing mobile terminal cannot use a local Volte service due to a location change can be solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an MBN update method and a mobile terminal. Background technique [0002] At present, there are more and more operators supporting Volte (Voice over LTE, a voice service based on a multimedia system) in various countries, and it has become a trend in the development of mobile terminals to support Volte of various operators as much as possible. Each operator corresponds to a specific modem configuration binary file (Modem Configuration Binary File, MBN), and the mobile terminal needs to store the corresponding MBN file in order to support the Volte of the operator. Due to the limited space of the encrypted file system (Encrypting File System, EFS) for storing MBN in the mobile terminal, it can only support the Volte of some operators. When the location of the mobile terminal changes, the Volte service cannot be used because the local MBN is not stored. . [0003] It can b...
