Problems solved by technology

[0014] The present invention is proposed in view of the problem that the core network in the prior art cannot trigger services for MTC terminals in an unattached (not attached) state. Therefore, the main purpose of the present invention is to provide a machine type communication terminal (Machine Type Communication Device, referred to as MD) business trigger method and device, to solve at least one of the above-mentioned problems

Embodiment 1

[0041] image 3 It is a preferred flowchart of a service triggering method of a machine type communication terminal according to an embodiment of the present invention, which includes the following steps:

[0042] S302. The machine type communication terminal detects that it is in an unregistered state or a registered state;

[0043] S304, the above machine type communication terminal migrates from the unregistered state or the registered state to a pre-registered state;

[0044] S306. The mobility management entity triggers a service on the machine type communication terminal in the pre-registration state.

[0045] In this preferred embodiment, the machine type communication terminal (MD) will migrate from the unregistered state or the registered state to the pre-registered state, because in the pre-registered state, the mobility management entity (MME) saves the machine type communication terminal identification information and location information, so that the MME can use...

Embodiment 2

[0054] In a preferred example of the present invention, the following technical solutions are adopted: a new EMM state is defined: EMM-PreREGISTERED state. Put the MD in the EMM-PreREGISTERED state when it is not attached. The MD can migrate from the EMM-REGISTERED state to the EMM-PreREGISTERED state or from the EMM-DEREGISTERED state to the EMM-PreREGISTERED state. In the EMM-PreREGISTERED state, the core network saves the location information and identification of the MD. The MTC server sends a service trigger indication to the MME, and the MME pages the MD after receiving the service trigger indication.

[0055] Further, when the MD is in the EMM-PreREGISTERED state, it will have the following characteristics:

[0056] 1) Do not initiate a periodic TAU process. The TAU process is initiated to the MME only when the TA (TrackingArea, tracking domain) of the MTC Device changes, and the terminal does not have a periodic TAU process similar to the EMM-REGISTERED state;

[00...

Embodiment 3

[0062] The present invention proposes to preset a new EMM-PreREGISTERED state for MD, and can migrate to this state when MD is not performing business. MD can migrate from the two states in the prior art to the newly defined state. It is divided into two embodiments for description.

[0063] When the MD is in the EMM-DEREGISTERED state, the MD can migrate to the EMM-PreREGISTER ED state through the pre-attach request process. The pre-attach request process can reuse the existing attach request process or adopt a new pre-attach request process. The message corresponding to the attach request process is an attach request message, and the message corresponding to the pre-attach request process is a pre-attach request message.

[0064] When the MD is in the EMM-DEREGISTERED state, it has the following characteristics:

[0065] 1) There is no valid UE location information in the context information in the MME, and the core network cannot page the UE.

[0066] 2) The periodic TA...

Abstract

The invention discloses a method and a device for triggering a service of a machine-type communication terminal. The method comprises the following steps that: the machine-type communication terminal detects that the terminal self is in un-registered state or registered state; the machine-type communication terminal transfers from the un-registered state or the registered state to a pre-register state; and a mobility management entity triggers the service for the machine-type communication terminal under the pre-register state. By using the method and the device, the problem that a core network cannot execute service triggering for the MTC (Machine Type communication) terminal in unattached state in the prior art can be solved, thereby realizing the effect of accurately triggering the service of the MTC terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a service triggering method and device for a Machine Type Communication Device (MD for short). Background technique [0002] M2M (Machine to Machine (Communication), Machine to Machine (Communication)) is a concept proposed in the 1990s and is an important driving force for the development of communication technology. Simply put, M2M is the Internet of machines, and the means of realization include various networking technologies. The goal of M2M technology is to enable all machines and equipment to have networking and communication capabilities, and its core concept is Network Everything. The communication objects of M2M are machine-to-machine or human-to-machine. Data communication between one or more machines is defined as MTC (Machine Type Communication, Machine Type Communication), in which less human-computer interaction is required. A machine participating in MTC is d...
