AI Technical Summary

Problems solved by technology

[0011] It can be seen from the above process that the existing technology is the download process of the profile sent from the network side (MNO). The MNO needs to know the identification (ID) of the eUICC in advance. Since the eUICC is different from the UICC, it is not necessarily purchased by the MNO centrally. It may be Purchased by the equipment manufacturer, so the MNO may not know the eUICC ID in advance. When the MNO does not know the eUICC of the equipment, the existing technical solution cannot be realized
In addition, in the above prior art, the download object of the profile can only be used by some authorized eUICCs from the beginning
In addition, since the profile is downloaded from the MNO on the network side, it must be ensured that the terminal device is powered on and connected to the SM-SR when the profile is downloaded, and the terminal user cannot freely choose the timing of profile download

Embodiment Construction

[0137] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0138] figure 1 It is a schematic flowchart of a method for downloading an operator's file provided by the first embodiment of the present invention. Such as figure 1 shown, which may include:

[0139] Step S110, the terminal obtains the download certificate for downloading the operator's file and the addressing information of the contract management-data preparation unit SM-DP storing the operator's file, the addressing information The address information is used to find the SM-DP.

[0140] In a specific implementation, the method for downloading an operator's file in the present invention can be executed from step S111, and step S110 can be a pre-step, that is, step S110 does not need to be performed before each operator's file is downloaded.

Abstract

The embodiment of the present invention discloses a method and device for downloading an operator's file, wherein one method includes: the terminal sends a download request of the operator's file to the SM-DP via the SM-SR, and the download request carries the downloading the credential and the ID of the eUICC of the terminal and the addressing information of the SM-DP; the terminal receives the operator's address corresponding to the download request sent by the SM-DP via the SM-SR file, and transmit it to the eUICC, the operator's file is after the SM-DP verifies that the download certificate of the operator's file carried in the download request is legal, according to the identification of the operator's file acquired. Thus, in the embodiment of the present invention, the download objects of the operator's files can be extended to all terminals, and the terminal users can freely choose the timing for downloading the operator's files.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and equipment for downloading files of operators. Background technique [0002] Embedded Universal Integrated Circuit Card (eUICC) is a traditional universal integrated circuit card (UICC) embedded in the terminal (encapsulation, welding, etc.), not pluggable, so there is no It can be replaced at will like a traditional UICC card. [0003] The existing SIM card or UICC card is generally ordered by the mobile network operator (Mobile Network Operator, MNO) from the card manufacturer, so the contract information required to access the mobile operator network has been downloaded to the card before leaving the factory , the user purchases a SIM card or UICC card and inserts it into the terminal to access the network; however, eUICC is not necessarily purchased by the operator, but may also be purchased by the terminal manufacturer and integrated into the terminal for sa...
