Device, system and method based on remote subscriber identity module (SIM) card data introduced by singlechip in real time

Abstract

The invention discloses a device, a system and a method based on remote subscriber identity module (SIM) card data introduced by a singlechip in real time. The device comprises mobile phone modules, the singlechip used for converting and transmitting remote SIM card data and a local SIM card converting circuit, wherein the mobile phone modules are connected with the singlechip and the local SIM card converting circuit through a data port. The system comprises an SIM card centralized management center, a testing terminal host computer, a serial port, testing terminal main control software and a device used as a remote testing terminal in the system. The mobile phone modules are connected through a mobile network; the singlechip and the local SIM card converting circuit are connected with the testing terminal host computer through the serial port; the testing terminal host computer is connected with the SIM card centralized management center through a TCP / IP network; and the testing terminal main control software is used for applying for a proper SIM card resource from the SIM card centralized management center and further processing and transmitting the SIM card data. In the invention, the SIM card on the testing terminal host computer is not needed to be distributed on terminal equipment in various regions and is only needed to be installed in the SIM card centralized management center, which is convenient for the centralized management of the SIM card.

Description

technical field [0001] The present invention belongs to the field of mobile communication, and particularly relates to a device that is implemented on a fixed-point test terminal device of a mobile network without installing a local SIM card. When necessary, the terminal applies for SIM data from the SIM card management center in real time and interacts with the mobile network. systems and methods. Background technique [0002] With the official reorganization of telecom operators and the final establishment of the three major operators, the competition among operators has been intensified, and it has become very important and urgent to improve their respective network quality and service quality. [0003] According to statistics, under normal circumstances in the city, the coverage and depth coverage of the mobile network basically reach 100%, but the network situation changes in real time, and the peak flow of people caused by new buildings, equipment damage, private equip...

Problems solved by technology

[0006] However, the common features of similar devices on the existing market are: a local SIM card must be installed on the device. When a new service needs to be verified, a new service must be opened for the number on the device. When a new number segment needs to be verified, a new number must be extracted. The number of the segment is manually installed on these fixed-point devices, and because these fixed-point devices are installed in unattended places, the SIM card on the device is easy to be stolen, and once stolen, it is easy to generate high consumption

The above reasons lead to the convenience of fixed-point test equipment for network optimization and business diversification, but also the inconvenience of SIM card management and use.
