Description

Method and device for acquiring code resource configuration file
Technical Field
The invention relates to the technical field of mobile communication, in particular to a method and a device for acquiring a code resource configuration file.
Background
Code resource configuration files (profiles) of a mobile communication network are key carriers for connecting users and network side operators, each code resource configuration file corresponds to a code resource, although the number of the code resources is huge, the code resources become insufficient as Universal Subscriber Identity Modules (USIMs) issued by the operators adopt a code resource pre-allocation mode, so that the code resources are not required as the yield of the USIMs is increased sharply, but the produced USIMs are not always put into use, and the utilization efficiency of the code resources is low.
In order to optimize the utilization efficiency of code number resources, an improved embedded universal Integrated Circuit Card (eUICC) adopts a mode of not pre-allocating code number resources (code number resource configuration files), when a terminal with the built-in eUICC Card is put into use, the code number resource configuration files are downloaded online from a mobile communication network operator in a code number resource configuration file online downloading mode to be installed so as to obtain the code number resources, and the utilization efficiency of the code number resources can be effectively improved. For example, a Local Profile Assistant (LPA) in the terminal acquires the eUICC card information from the eUICC card, for example, a digital certificate of the eUICC card, performs mutual authentication with a Subscription Data management-Data Preparation (SM-DP) server through WIFI (without pre-provisioning a code number) or a cellular network, and downloads a code number resource Profile from the SM-DP server after the authentication is passed. However, in the method for acquiring the code resource configuration file, the operator has many limitations on the communication between the LPA and the eUICC card in view of communication security, for example, the apple terminal does not open a communication interface between the LPA and the eUICC card, while in the android terminal, the LPA is used as a user APP and can communicate with the eUICC card only after acquiring the system permission. Therefore, due to access limitation between the LPA and the eUICC card in the terminal, the success rate of the terminal for acquiring the code resource configuration file on line is not high, and the use of the terminal is influenced.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In the existing method for acquiring the code resource configuration file online, an LPA in a terminal needs to communicate with an eUICC card to acquire information of the eUICC card for authenticating with an SM-DP server from the eUICC card, so as to realize online downloading of the code resource, and transmit the code resource configuration file downloaded from the SM-DP server to the eUICC card for installation. However, in the prior art, because there are many security access restrictions on the direct communication between the LPA and the eUICC card, the LPA cannot acquire the information of the eUICC card through the direct interaction with the eUICC card, so that the eUICC card cannot perform interactive authentication with the SM-DP server, and the code resource configuration file cannot be downloaded online from the SM-DP server, so that the success rate of acquiring the code resource configuration file online by the terminal is not high, and the use of the service by the user is affected.
Near Field Communication (NFC) is a type of Near Field Communication that allows direct connection between electronic devices for contactless point-to-point data transmission via a Single Wire Protocol (SWP). In order to realize a fast and mobile payment function in the fields of transportation, finance and the like, most of the conventional terminals are provided with a contact Front-end (CLF) module for NFC, the CLF module is directly connected with a payer through an SWP protocol, and data is transmitted by calling an NFC interface to realize the fast and mobile payment function. In the embodiment of the invention, a CLF module which is arranged in a terminal and supports an NFC interface is utilized to establish near field communication connection with an eUICC card through an SWP protocol for communication, because the SWP protocol is a protocol which adopts direct connection to transmit data, the communication between the CLF module and the eUICC card has no access limit, and the CLF module can acquire eUICC card information from the eUICC card and transmit the eUICC card information to an LPA (low power access architecture) through calling the NFC interface, thereby avoiding the situation that code number resource configuration files cannot be downloaded on line due to the access limit between the LPA and the eUICC card in the terminal.
