Data transmission method for having access to cellular mobile network system and associated equipment

Abstract

The embodiment of the invention provides a data transmission method for having access to a cellular mobile network system and associated equipment. Only necessary data are transmitted between a cloud server and the terminal equipment, and resources of a communication network are saved. The method includes the steps that the cloud server receives access place information sent by the terminal equipment; according to the access place information, SIM cards or USIM cards are distributed, and associated data of the cards are acquired; the associated data are processed, and a data set is acquired; historical login place information of the terminal equipment is acquired, the access place information and the historical login place information are compared, whether the terminal equipment has access to a service provider network of an access place before or not is judged, if yes, the first kind of data are transmitted to the terminal equipment, and if not, the first kind of data and the second kind of data in the data set are transmitted to the terminal equipment. The embodiment of the invention further provides the cloud server. The embodiment of the invention further provides the terminal equipment.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a data transmission method and related equipment for accessing a cellular mobile network system. Background technique [0002] At present, terminal equipment uses a variety of technologies and formats according to the selected operator, including Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Universal Mobile Communication System (Universal Mobile Telecommunications System, UMTS) and Long Term Evolution (Long Term Evolution, LTE) and other technologies, using Subscriber Identity Module (Subscriber Identity Module, SIM) card or Universal Subscriber Identity Module (Universal Subscriber Identity Module, USIM) card storage allows terminal equipment The necessary identity and service data to communicate with the mobile communication network, the SIM / USIM card is a removable smart card, and also contains a lot of personal data, such as integra...

Problems solved by technology

[0005] However, the cloud server needs to obtain all the data of the USIM card, and the terminal equipment basically uses a roaming module and a local module to complete the remote scheduling of the USIM card under the cloud server and the local access of the terminal equipment, so the terminal equipment has The two modules need to be powered on, and there will be two network search processes and two USIM card reading processes. Every time the terminal device is powered on, it needs to establish a connection with the cloud server to transmit USIM card data, and these data are all through roaming. network, resulting in high operating costs and waste of resources
