Problems solved by technology

In addition, the operator is changed by changing the International Mobile Subscriber Identity (IMSI). Although M2M devices can be easily managed, this solution requires the IMSI to be transferred between the networks of different operators, which will increase the Security Risk

Embodiment Construction

[0050] In the present invention, the MCIM of the M2M device and the USIM or ISIM of the UICC manufacturer or issuer are located on the same UICC. When the M2M device needs to change the subscription data, after the USIM or ISIM of the UICC is activated, an initial connection is established with the USIM or ISIM home network through the USIM or ISIM; the new subscription data of the M2M device sent by the new home network of the M2M device is received through the initial connection , to realize the change of MCIM.

[0051] In the present invention, when the MCIM of the M2M device is located on the UICC, the MCIM may specifically refer to a USIM, an ISIM, and the like. For the convenience of description, in the solution of the present invention, the subscription data of the M2M device is represented by MCIM. When only the IMSI is involved, in this document, the subscription data of the M2M device may also simply refer to the IMSI of the MCIM. The subscription data of the UICC ...

Abstract

The invention discloses a system, a method and equipment for changing signature data. Based on the technical scheme, when M2M (Machine to Machine) equipment needs to change the signature data, after a USIM (Universal Subscriber Identity Module)/ISIM (International Subscriber Identity Module) of a UICC (Universal Integrated Circuit Board) is activated, initial connection is established through the USIM/ISIM and a USIM/ISIM home network; the change of an MCIM (Machine Communication Identity Module) is realized by receiving new signature data sent by a new home network with the initial connection; according to the technical scheme of the invention, the new signature data is transferred through the USIM/ISIM home network without transferring the new signature data among networks of different operators, thereby strengthening the safety of the signature data and conveniently and rapidly finishing the change of the signature data. In addition, aiming to the condition that the USIM/ISIM of the MCIM and the USIM/ISIM of the UICC are arranged in a same UICC, the UICC is not needed changing, thereby lowering the cost. Therefore, the invention safely and conveniently realizes the change of the signature data of the M2M equipment.

Description

technical field [0001] The present invention relates to machine-to-machine (M2M, Machine to Machine) communication technology, in particular to a system, method and device for changing M2M equipment (M2ME) subscription data. Background technique [0002] M2M is a general term for a series of technologies and their combinations that apply wireless communication technology to realize data communication and exchange between machines and machines, and between machines and people. M2M has two meanings: the first meaning is the machine itself, which is called a smart device in the embedded field; the second meaning is the connection between machines, which connects machines together through the network. Machine-type communication has a wide range of applications, such as intelligent measurement, remote monitoring, tracking, medical treatment, etc. M2M makes human life more intelligent. Compared with traditional human-to-human communication, M2M devices have a huge number and wide...
