Problems solved by technology

But in the MTC system, the M2M terminal may only interact with the MTC server through the gateway, without passing through the SMS center. Therefore, in this case, the communication between the M2M and the MTC server cannot be realized by using the WAP gateway.
[0010] In addition, in practical applications, the MTC server may interact with the network not only through signaling, but also through TCP / IP, or through short messages.
If a WAP gateway is used, since the WAP gateway can only convert short messages to TCP / IP, it cannot guarantee the diversity of MTC server access

Embodiment 1

[0078] This embodiment describes how the IWF obtains the subscription data of the MTC UE during the registration process of the MTC UE. In this embodiment, when the mobility management network element receives the attach request sent by the MTC UE, it sends a location update request to the IWF, In order to enable the IWF to acquire the subscription data of the MTC UE. Figure 6 It is a flow chart of obtaining subscription data by IWF in this embodiment, such as Figure 6 As shown, it mainly includes the following steps:

[0079] Step 601, the MTC UE initiates an attach request to a mobility management network element in the network, and the attach request carries identification information of the MTC UE and capability information of the MTC UE;

[0080] Step 602, the mobility management network element determines that the UE is a machine-type terminal based on the identification information of the MTC UE or the capability information of the MTC UE;

[0081] Step 603, the mob...

Embodiment 2

[0088] The difference from Embodiment 1 is that in this embodiment, the registration process of the MTCUE in the IWF is performed after the attachment is completed. Specifically, during the attachment process of the MTC UE, the MTCUE obtains the address of the IWF, and then sends a registration request message to the IWF , the IWF obtains the MTC UE subscription data from the user subscription data storage network element. Figure 7 Be the flow chart of this embodiment, such as Figure 7 As shown, it mainly includes the following steps:

[0089] Step 701, the MTC UE completes the attachment process to the network and obtains the address of the IWF;

[0090] Step 702, the MTC UE sends a registration request to the IWF, and the registration request carries the identification information of the MTC UE;

[0091] In a specific implementation process, the identification information of the MTC UE may be IMSI, or other information identifying its identity;

[0092] Step 703, the IW...

Embodiment 3

[0097] In this embodiment, when the IWF receives the request sent from the MTC server to the MTC UE, the IWF selects a suitable bearer domain and transmission mode for the UE.

[0098] In this embodiment, the MTC UE is accessed through the GSM network, and the service data is carried by the CS domain. Figure 8 It is a flow chart of the message transmission method in this embodiment, such as Figure 8 As shown, it mainly includes the following steps:

[0099] Step 801, the MTC server sends a data transmission request to the IWF, and the data transmission request carries the identification information and capability information of the MTC UE;

[0100] Step 802, the IWF obtains the subscription data of the MTC UE stored locally, and obtains the subscription attribute of the MTC UE from the subscription data. In this embodiment, the subscription attribute of the MTC UE indicates that the MTC UE can only use the CS domain to carry services data;

[0101] In step 803, the IWF se...

Abstract

The invention discloses a machine type communication (MTC)-based message transmission method and an interworking functional entity. The method comprises that: the interworking functional entity receives message from an MTC terminal; the interworking functional entity acquires the address of an MTC server; and the interworking functional entity converts the message into a format according with the interaction mode of the MTC server, and sends the converted message to the MTC server in an interaction mode. By the method, access diversity of the MTC server can be ensured.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a message transmission method and an interworking functional entity based on machine type communication. Background technique [0002] The narrow definition of Machine to Machine (M2M) refers to machine-to-machine communication, and the broad definition refers to networked applications and services centered on the intelligent interaction of machine terminals. It is based on intelligent machine terminals and uses multiple communication methods as access means to provide customers with informatization solutions to meet customers' informatization needs in monitoring, command and dispatch, data collection and measurement. [0003] At present, the M2M terminal can be connected through various communication systems such as Global System for Mobile Communication (GSM for short), Universal Mobile Telecommunications System (UTMS for short), and Evolved Packet System (EPS for short). W...
