Remote card writing method, device and system

Abstract

The invention discloses a remote card write-in method, device and system. The remote card write-in method comprises interactively executing an OTA (Over The Air) card write-in business with a network side, obtaining number resource information corresponding to a first communication number from the network side, and writing the number resource information in an EFIMSI file of a smart card; emptying information in an EFLOCI file of the smart card; starting a communication process, obtaining number resource information contained in the EFLOCI file, determining the number resource information to be empty and then reading number resource information from the EFIMSI file of the smart card; performing communication with an OTA platform by utilizing the read number resource information, and determining whether the card write-in operation is successful according to a communication number contained in a communication response fed back by the OTA platform; determining that the operation is successful if the communication number is the first communication number. According to the remote card write-in method, device and system, due to the fact that the EFLOCI file is emptied during a card write-in process, when a user uses a smart card in which a new number is written for communication, a terminal device of the other party can display the information of the new number, and a user can correctly judge whether the card write-in business is executed successfully.

Description

technical field [0001] The invention relates to the technical field of telecommunications, in particular to a remote card writing method, device and system. Background technique [0002] In order to improve the utilization rate of number resources and enrich the issuance methods of smart cards, the over-the-air card writing service was developed and proposed. This service can be completed independently by the user, and its core technology is: when issuing the card, a set of personalized data, that is, a preset number, is preset in the telecom smart card; the user places the card in the terminal device, and uses the Log in to the online business hall with a preset number, self-select a new number, package and tariff type, and send a card writing request uplink; the over-the-air card writing remote management platform processes the business request, obtains the new number data and sends it to the over-the-air download platform (Over The Air) , hereinafter referred to as OTA);...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a remote card writing method, device and system, which are used to solve the problems in the prior art that after the air card writing business is completed, within a short time after the user completes the card writing business, when the user uses a smart card with new number data written During communication, the information of the preset number is still displayed on the terminal equipment of the other party. This phenomenon makes it difficult for the user to judge whether the over-the-air card writing service is successfully executed.
