Description

Network-free SIM card opening method, terminal equipment and operator server

Technical Field

The invention relates to the technical field of communication, in particular to a network-free SIM card opening method, terminal equipment and an operator server.

Background

With the technology of TEE (Trusted Execution Environment) becoming mature day by day, the vSIM (virtual SIM) technology based on the TEE scheme of the processor chip gradually becomes a scheme of replacing a physical SIM (Identity authentication Module) card, which is optional in the telecommunication field except for an eSIM (embedded SIM), with the advantages of no need of an independent security chip, low cost, convenience for expansion and the like while meeting the security requirement. In the vSIM technical scheme, a user can directly carry out network account opening and resource downloading of an operator without using a physical SIM card or adding a special eSIM patch card in terminal equipment, so that the SIM card is opened to use wireless network service provided by the operator, the manufacturing cost is saved for terminal equipment manufacturers, and the convenience of opening the SIM card by common consumers and enterprise users is also improved. Meanwhile, the vSIM scheme realized based on the TEE technology can also be realized by fully utilizing the existing hardware equipment with the TEE function, so that the technical application threshold is reduced, and the investment cost is reduced. For example, many terminal devices have built-in TEE functions in their chips, and these terminal devices can support the vSIM by software upgrade without requiring users to purchase new terminal devices. When the terminal device opens the SIM card, a corresponding profile needs to be obtained, where the profile refers to a collection of code number resources and corresponding data, file systems, applications, and the like. After a user purchases terminal equipment supporting vSIM, if the user wants to download the profile required by the vSIM through local operation, the terminal equipment must be accessed to a network, and a feasible scheme is to realize profile downloading through a wifi access network, but wifi does not exist in many scenes, so that a scheme for downloading operator profile by the terminal equipment under the condition of no network is required.

Currently, the vSIM is mainly used for international traffic resale, such as Hua is an interplanetary communication scheme, an OPPO international internet access scheme and the like. In some schemes, packages are purchased and profiles are downloaded through an own APP before a user leaves a country under the condition of a network, and the profiles contained in the packages are directly started after the user arrives overseas, so that the scheme needs to purchase packages and download profiles in advance, is complicated, and can also face the situation of no network availability when the user arrives overseas and forgets to purchase packages in advance; in some schemes, a seed number of a specific operator is built in an own APP, when a user arrives overseas and a physical SIM card cannot surf the internet, the APP starts the built-in seed number to access a website of the specific operator to purchase a package, and downloads and starts a profile after the package purchase is completed, wherein the scheme can only download the profile of the specific operator. The above solutions are all for reselling international traffic, and it is impossible for the terminal device to select a local operator and directly download the profile of the operator without a network.

Whereas for esims, the provisioning of their SIM card is mainly dominated by the operator. The eSIM scheme adopted by the current operator is mainly an eSIM scheme recommended by GSMA (Global Mobile Communications Association), and in this scheme, a user needs to obtain a two-dimensional code of an eSIM profile through a network or a local operator APP or a business hall of the local operator, and under the condition that a terminal device can access the network, for example, an existing SIM card of the terminal device is accessed into the wireless network, or the wireless network is accessed through wifi, and the two-dimensional code provided by the operator is scanned, so that the card opening process can be entered. In this case, if the terminal device of the user is newly purchased and there is no network at all, the download of the eSIM profile cannot be realized.
