Abstract

Upon transmitting privacy information to an MTC server (20) via a network (30, 40), an MTC device (10) includes in a message a field to indicate whether the message contains the privacy information, such that the network (30, 40) can perform authorization for the MTC device (10) and server (20). When the MTC device (10) needs to keep connection with the network (30, 40), the MTC device (10) switches off the functionality of provisioning the privacy information, such that the MTC device (10) still can communicate with the network (30, 40). Upon the transmission of privacy information in an emergency case, the MTC device (10) further includes in the message a content to indicate that the MTC device (10) is an emergency device, such that the network (30, 40) verifies whether the MTC device (10) can be used or activated in the emergency case. Optionally, a USIM for emergency-use is deployed in the MTC device (10).

Claims

1-33. -33. (canceled)

34. A terminal, comprising:

a controller configured to serve as an MTC (Machine-Type-Communication) device in an M2M (Machine-to-Machine) communication system which includes an MTC sever and a network including an MME (Mobility Management Entity) or an SGSN, and an MTC-IWF (Machine Type Communication Interworking Function); and

a receiver configured to receive a trigger request from the MTC server which is authorized to send the request by the network;

wherein the network monitors a location information of the MTC device in response to a change of location of the MTC device according to the request of the network.

35. The terminal according to claim 34, the MTC server connects to a communication partner of the terminal.

36. A communication method of a terminal, comprising:

serving as an MTC (Machine-Type-Communication) device in an M2M (Machine-to-Machine) communication system which includes an MTC sever and a network including a network including an MME (Mobility Management Entity) or an SGSN, and an MTC-IWF (Machine Type Communication Interworking Function); and

receiving a trigger request from the MTC server which is authorized to send the request by the network;

wherein the network monitors a location information of the MTC device in response to a change of location of the MTC device according to the request of the network.

37. The method according to claim 36, the MTC server connects to a communication partner of the terminal.

38. A network in an M2M (Machine-to-Machine) communication system which includes a terminal serving as an MTC (Machine-Type-Communication) device and an MTC sever, comprising:

an MME (Mobility Management Entity) or an SGSN; and

an MTC-IWF (Machine Type Communication Interworking Function);

wherein the network authorizes the MTC server to send a trigger request to the MTC device and monitors a location information of the MTC device in response to a change of location of the MTC device according to the request of the network.

39. The network according to claim 38, the MTC server connects to a communication partner of the terminal.

40. A communication method of a network including an MME (Mobility Management Entity) or an SGSN and an MTC-IWF (Machine Type Communication Interworking Function) in an M2M (Machine-to-Machine) communication system which includes a terminal serving as an MTC (Machine-Type-Communication) device and an MTC sever, comprising:

authorizing the MTC server to send a trigger request to the MTC device; and

monitoring a location information of the MTC device in response to a change of location of the MTC device according to the request of the network.

41. The method according to claim 40, the MTC server connects to a communication partner of the terminal.
