Method and system for mobile terminal to select VOLTE according SIM card

Abstract

The invention discloses a method and a system for a mobile terminal to select VOLTE according an SIM card. The method comprises the following steps of establishing a relation table of a PLMN of a preset SIM card and a preset ID value, dynamically searching through PLMN codes of the SIM card and querying the relation table to judge whether the PLMN exists and needs updating; obtaining an ID value of the current SIM card when the PLMN exists and needs updating, and obtaining a default ID value when the PLMN does not exist; and obtaining related configuration parameters according to the obtained ID. When the different SIM cards are dynamically inserted, the different IMS configuration information and a correct VOLTE network are configured according to the PLMN values and mobile terminals of different operators, so that the same software can be automatically compatible with the different IMS configuration information according to the type of the SIM card and dynamically select the VOLTE network, and thus the maintenance and management cost of the codes is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminal applications, in particular to a method and system for a mobile terminal to select VOLTE according to the type of SIM card. Background technique [0002] With the development of IMS (IMS: IP Multimedia Subsystem, IP Multimedia Subsystem, which is a brand-new multimedia service form, which can meet the needs of newer and more diversified multimedia services of current terminal customers), IMS has been able to meet Today's terminal customers have more novel and more diverse multimedia business needs. [0003] VOLTE is an IMS-based voice service. IMS has become the core network standard architecture in the all-IP era because it supports multiple access and rich multimedia services. VOLTE is Voice Over LTE. It is an IP data transmission technology that does not require 2G / 3G networks. All services are carried on the 4G network, which can realize the unification of data and voice ...

AI Technical Summary

Problems solved by technology

[0007] In the software development and production stage of the project, due to the inconsistency of the IMS configuration parameters of the mobile phone terminal required by the IMS systems of different operators in different countries around the world, it is necessary to output software with different IMS configuration information according to different SIM cards of different operators, which will increase version maintenance costs. , leading to the problem that the same software cannot be compatible with the SIM card, and the difference in IMS configuration information between different SIM cards leads to the problem that different software is required to realize the registration of the VOLTE network
