Embodiment 1

[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] in, Figure 5 It is a schematic flowchart of the communication method of the MTC terminal in the present invention.

[0052] Such as Figure 5 As shown, the communication method of the MTC terminal includes the following steps:

[0053] S101: The MTC terminal reports the MTC terminal information to the central control node;

[0054] Wherein, specifically, the MTC terminal information is information necessary for the MTC terminal to initiate non-access stratum signaling to the core network node;

[0055]S102: The central control node (GW) obtains the MTC terminal information, and obtains the necessary MTC terminal information for generating non-access stratum (NAS layer) signaling from the above MTC terminal information;

[0056] Wherein, in S102, the MTC terminal information here represents the necessary messages for generating the...

Embodiment 2

[0069] The following combination Figure 6 ~ Figure 8 Various scenarios of interaction between the MTC terminal and the core network shown further illustrate the communication method of the MTC terminal of the present invention.

[0070] Image 6 In the illustrated embodiment, the MTC terminal requests network registration from a core network node, wherein the MTC terminal is quasi-stationary, and uses the IMSI in the SIM / USIM or the device IMEI for authentication and authentication.

[0071] Such as Image 6 As shown, the communication method of the MTC terminal further includes the following steps:

[0072] S201: The MTC terminal starts up and requests a network registration request from the core network node;

[0073] S202: The MTC terminal transmits the MTC terminal access request information of the non-access stratum instruction for initiating a network registration request to the core network node to the central control node;

[0074] According to this embodiment, th...

Abstract

The invention discloses a communication method of a machine-type communication (MTC) terminal. The communication method of the MTC terminal comprises that the MTC terminal reports MTC terminal information to a center control node; and the center control node forms a corresponding non-access layer signal according to the MTC terminal information, and sends the non-access layer signal to a core network node. The communication method of the MTC terminal has the advantages of reducing complexity of the design of the MTC terminal, saving expenses of an air interface resource which is used for starting a non-access stratum (NAS) signal, wherein the air interface resource is relevant to the MTC terminal, thereby reducing energy consumption of the MTC terminal, and creating conditions for deployment of MTC services. In addition, the invention further discloses a communication system and the center control node of the MTC terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, to a communication method for an MTC terminal and a communication method for an MTC terminal. Background technique [0002] MTC (machine-type communication, machine-type communication) refers to a communication method between machines (device-to-device) without human participation. [0003] The current core network specification 3GPP 22.368 defines 16 important features in MTC communications, including low mobility, time control, delay tolerance, and online small data transmission. For different applications, such as meter reading, smart home and vehicle control, it may have one or several of the above 16 characteristics. However, due to the large number and various types of MTC terminals, it is difficult to unify relatively consistent characteristics. However, how to reduce the production cost of MTC terminals, reduce air interface resources and terminal power consum...
