Problems solved by technology

[0003] With the development of technology, users now rely more and more on handheld devices to stay connected to the Internet at any time. However, in many cases, the network coverage of mobile operators cannot meet the needs of users. For example, the network signal coverage of different operators is different. However, the users of operator A cannot use the network of operator B where the coverage of operator A is weak and the coverage of operator B is strong. Roaming networks will incur expensive data roaming charges
However, due to business competition and billing standard issues among operators, the cost of business cooperation is too high
In addition, the purchase and replacement of the SIM card will also bring a lot of inconvenience to the user communication.

Embodiment

[0019] The Internet of Things relay SIM card data communication method of this embodiment is used for data communication of terminal equipment. The terminal equipment is provided with a relay SIM card. The relay SIM card contains a communication module and can perform 2G / 3G / 4G communication. The operator network completes the authentication process between the relay SIM card and the SIM card hosting server and the original SIM card, and the relay SIM card can store the authenticated key value, which is used to replace the original SIM card to provide data encryption for the baseband of the mobile phone key.

[0020] see figure 1 , the method includes the following steps:

[0021] 1) Establish a SIM card hosting server that inserts multiple original SIM cards; for example, a SIM card hosting server can insert 1024 original SIM cards at the same time, and the original SIM cards can be SIM cards of any operator in the world.

[0022] 2) The terminal device sends a connection ...

Abstract

The invention relates to an Internet-of-things relay SIM card data communication method comprising the following steps: multiple original SIM cards are inserted into an SIM card hosting server; a terminal device with a relay SIM card issues a connection request to the SIM card hosting server, first, the Bluetooth is connected with the Bluetooth of a nearby mobile phone, and then, the mobile phone sends the geographical location of a customized terminal to the SIM card hosting server via a network, and the SIM card hosting server selects and sends the most suitable original SIM card information to the terminal device; and the customized terminal device issues a data communication request, the relay SIM card sends an authentication request containing authentication parameters to the mobile phone, the mobile phone sends the authentication request to the corresponding original SIM card via a network and returns a key value of the original SIM card after authentication to the relay SIM card, and the terminal device starts data communication. By replacing an original SIM card with a relay SIM card, the problem that business cooperation costs too much is solved. The method is especially suitable for Internet-of-things applications.

Description

technical field [0001] The invention relates to a data communication method for relaying SIM cards of the Internet of Things, belonging to the technical field of Internet of Things applications. Background technique [0002] Nowadays, many handheld devices such as mobile phones (Mobile Phone), mobile network devices (MID), etc. need to insert independent SIM cards to access the operator's wireless network. When users bring these devices into a certain mobile operator's network coverage blind area time, or when going abroad, it is necessary to replace the SIM card of other operators in order to receive services normally. The encryption algorithm used for user identification and the corresponding original key are stored on the SIM card. The operator's network side checks whether the current user has corresponding context information according to the IMSI / TMSI information reported by the user. If not, authentication is performed to ensure that legitimate users use communicatio...
