Abstract: The present disclosure discloses a method and system for triggering a Machine Type Communication MTC device. The method includes that: an MTC server sends a Bootstrapping Server Function entity BSF a request message including information on a GBA-PUSH Information GPI request and information on a triggering request; the BSF generates GPI and adds parametric information of a triggering instruction in the GPI according to the information on the triggering request through a GPI request processing flow, and sends the GPI including the parametric information of the triggering instruction to the MTC server; the MTC server sends the GPI including the parametric information of the triggering instruction to an MTC device to be triggered; and the MTC device is triggered according to the parametric information of the triggering instruction in the received GPI.

Abstract: The disclosure discloses a key sharing method for a Machine Type Communication (MTC) server, wherein when establishing a safe connection and performs safe communications with a first MTC server via a Generic Bootstrapping Architecture (GBA) process, an MTC device may send a second MTC server a request message containing a bootstrapping identifier (B-TID) currently used by the MTC device and the first MTC server and a host identifier NAF-ID1 of the first MTC server; the second MTC server sends a Bootstrapping Server Function (BSF) an authentication request containing a host identifier NAF-ID2 of the second MTC server, the B-TID, and NAF-ID; after verifying the validity of NAF-ID2 and NAF-ID1, the BSF generates a session key KNAF according to the B-TID and the NAF-ID1, and sends the generated KNAF to the second MTC server. Accordingly, the disclosure further discloses a key sharing system for an MTC server.

Abstract: A method and a system for changing the Selected Home Operator (SHO) of a Machine to Machine Equipment (M2ME) are disclosed. The method includes: the M2ME establishing a connection with a Registration Operator (RO) through a Trusted Environment (TRE) functional entity, the RO registering the M2ME in the new SHO; the new SHO sending the new International Mobile Subscriber Identity (IMSI) to the RO or authorizing the RO to provide a new IMSI after it has passed the verification of the M2ME by the Platform Validation Authority (PVA); the RO sending the new IMSI to the M2ME through the connection established by the TRE functional entity; the M2ME replacing the old IMSI in the Universal Integrated Circuit Card (UICC) with the new IMSI; wherein the UICC and the TRE function entity are all located in the M2ME.

Abstract: A method and system for changing a SHO of a M2ME are provided. The method includes: mode one: a new SHO receiving parameters of the M2ME, after the M2ME passes the verification by a PVA, providing a MCIM of the new SHO to the M2ME through a connection between the M2ME and a RO provided by an old SHO; and the M2ME installs the new MCIM in a UICC; or, mode two: a new SHO receiving parameters of the M2ME, after the M2ME passes the verification by a PVA, providing a MCIM of the new SHO to the M2ME through a connection between the M2ME and a RO established by a TRE functional entity; and the M2ME installs the new MCIM in a UICC; and both the UICC and the TRE functional entity are located in the M2ME. The present invention is able to change the SHO of the M2ME.
