Description

eSIM profile updating method

Technical Field

The invention relates to the technical field of Internet of things, in particular to an embedded Subscriber identity Module (eSIM) code number configuration file (profile) updating method.

Background

The industry has different proposals for esims. For example, eSIM or embedded Universal Integrated Circuit Card (eUICC) refers to various proposals of the third Generation Partnership Project (3rd Generation Partnership Project, 3GPP), GSM association (GSM System for Mobile Communications infrastructure, GSMA), and European Telecommunications Standardization Institute (ETSI). Collectively expressed herein as esims.

The profile represents a file system, file contents, and applications on the eSIM operating system, and mainly carries information such as an IMSI (International Mobile Subscriber identity Number), an authentication parameter, and is uniformly expressed as a profile or a configuration file in this document.

The eSIM occupies small space, has high equipment safety, and is widely applied in partial wireless access scenes, especially scenes such as the Internet of things and wearable equipment.

At present, profile initialization and update of eSIM generally have the following schemes:

1. for a terminal with an operation interface (such as a common consumer terminal), the eSIM management platform can be safely accessed and the profile can be remotely refreshed through means of configuring or scanning two-dimensional codes and the like and through wireless channels such as WiFi and the like.

2. For terminals (such as smart watches and smart phones) capable of being provided with master and slave devices, the slave devices can be connected with the master device in a Bluetooth mode and the like, and then the master device is accessed into an eSIM management platform to remotely refresh the profile.

3. And (3) agreeing with a certain operator, a certain number segment profile is pre-built in the terminal, and the profile is remotely refreshed after the terminal is accessed to the operator network.

4. The near end is connected to the terminal through a special tool to refresh the profile.

The existing profile updating scheme is not suitable for the private network Internet of things because the private network Internet of things has the particularity of small terminal quantity, single terminal wireless connection mode, high safety requirement and the like. The specific analysis is as follows:

1. the internet of things of the private network is different from the public network, the delivery volume of the private network terminal is small, and the method that a factory presets the profile in batches according to projects is not suitable for being adopted in consideration of cost factors.

2. Often, a dedicated internet of things scene has no remote means other than wireless connection supported by eSIM, and therefore, profile cannot be updated in a bluetooth manner or the like.

3. The terminal equipment of the internet of things has poor operability and is not suitable for updating the profile by a special tool at the near end.

4. Limited by the size of the business or other reasons, it is difficult to negotiate with the operator to adopt the updating mode of the preset operator profile.

5. Due to the high requirements on privacy and security of the private network, the profile is not approved to be upgraded through a third-party network.

At present, an eSIM profile updating scheme suitable for a private network internet of things is not provided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The core idea of the invention is as follows: planning a preset PLMN ID in advance, preassembling the PLMN ID available for the private network in advance in a factory, and completing the updating of the eSIM profile under the private network through the cooperation of a network side base station and a core network account opening.

Fig. 1 is a schematic method flow diagram according to an embodiment of the present invention, and as shown in fig. 1, the eSIM profile updating method implemented by the embodiment mainly includes:

step 101, presetting a seed code number public land mobile network identifier (PLMN ID) and a seed code number configuration file profile set corresponding to each seed code number PLMN ID.

It should be noted here that when planning the preset seed PLMN ID, care needs to be taken to avoid collision with the known operator PLMN ID and each item PLMN ID. In addition, the maximum profile number in the control set needs to be paid attention to, on one hand, the situation that the profile of each project account opening user is repeated due to too small number is avoided, and on the other hand, the situation that the network account opening specification is influenced due to too large number is avoided.

Therefore, preferably, the seed code number PLMN ID is a currently unused and unplanned PLMN ID, and the number of profiles in the profile set matches the number of users of the project.

And 102, before each terminal device leaves the factory, presetting seed profiles in corresponding eSIM by using the profile set, and recording a mapping relation between an International Mobile Equipment Identity (IMEI) of the terminal device and the preset seed profiles.

Preferably, in this step, the seed profile may be preset in the eSIM of the terminal device by using the following method:

before the terminal equipment leaves a factory, one seed profile is respectively selected from each profile set, and the selected seed profile is preset in the eSIM of the terminal equipment.

By adopting the method, the seed profiles corresponding to different seed code numbers PLMN ID are preset in the terminal equipment, so that the seed profiles corresponding to the PLMN ID received from the broadcast can be used for accessing the network after the terminal equipment is started.

103, when a private network project is opened, configuring a PLMN ID for updating the profile in the base station by using the seed code number PLMN ID, and broadcasting the PLMN ID through a system message; and for each terminal device of the private network project, determining the seed profile used by the terminal device according to the mapping relation, the PLMN ID for updating the profile and the seed profile preset in the eSIM, and opening an account for the terminal device in a core network according to the determined seed profile.

Preferably, the PLMN ID for updating the profile may be configured in the base station by specifically adopting the following method:

In step 103, when the private network project is opened, a PLMN ID for updating the profile is configured for the project in the base station and the PLMN ID is broadcast, so that the currently used seed profile can be determined according to the PLMN ID after the terminal device of the project is turned on. In addition, the core network will also open an account for the terminal device according to the IMSI and authentication information in the seed profile.

104, when the terminal equipment is started, determining the seed profile used by the terminal equipment by using the PLMN ID acquired from the broadcast message, and accessing the network by using the seed profile; and after the terminal equipment is successfully attached, acquiring the actually used profile by butting with the eSIM management system, and accessing the network by using the actually used profile.

In practical application, after the terminal device is started, the PLMN ID broadcasted by the base station is obtained from the broadcast message, and the PLMN ID is the PLMN ID used for updating the profile, so that the terminal device can select the seed profile corresponding to the PLMN ID from the seed profiles preset in the terminal device, and use the seed profile to access the network, and obtain the profile actually used by docking with the eSIM management system.

According to the scheme, aiming at the characteristics of the private network Internet of things, the embodiment presets the PLMN ID in advance through planning, the seed profile available for the private network is pre-installed before the terminal leaves a factory, and the updating of the eSIM profile under the private network is realized through the cooperation of the network side base station and the core network account opening. By adopting the embodiment, the near-end profile of the terminal of the Internet of things can be prevented from being updated in a small scale, the upgrading efficiency is greatly improved, the operation and maintenance effect is better, and a mode that a factory presets the profile in batches according to projects is not needed, so that the cost can be effectively reduced. In addition, the scheme can also avoid the business problem of renting a public network operator network.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
