Embodiment 1

[0066] Figure 4 It is a schematic flowchart of Embodiment 1 of the method for indicating a message type in the present invention, and is aimed at a scenario where a user equipment initiates MO signaling, such as Figure 4 As shown, the method includes the following steps:

[0067] Step 401, the user equipment sends NAS signaling to the MME or SGSN, and adds a message type indication bit to the NAS signaling;

[0068] Specifically, the user equipment sends NAS signaling to the MME or SGSN, and adds message type indication bits to the NAS signaling; the NAS signaling can be the NAS signaling sent by the user equipment during any of the following signaling processes: connection Request (Attach Request), service request (Service Request), TAU / RAU Request, etc.; the NAS signaling includes user plane data Small Data; the size of the Small Data is generally determined by the user subscription data or the operator's operation or maintenance entity ( O&M, Operation and Maintenance) ...

Embodiment 2

[0088] Figure 5 It is a schematic flow diagram of Embodiment 2 of the method for indicating the message type in the present invention, for the scenario where the network side sends MT signaling, Figure 5 As shown, the method includes the following steps:

[0089] In step 501, the MTC Server adds message type indication bits in the control plane signaling; wherein, the control plane signaling refers to the signaling between the MTC Server and the P-GW or GGSN or MTC-IWF.

[0090] Step 502, the MTC Server judges whether the control plane signaling is sent through the MTC-IWF, if yes, execute step 503, otherwise, execute step 510;

[0091] Specifically, the MTC Server may judge by itself or select whether the control plane signaling is sent through the MTC-IWF according to an O&M instruction; if yes, perform step 503; otherwise, perform step 510.

[0092] Step 503 , the MTC-IWF receives the control plane signaling, judges whether the control plane signaling contains user plan...

Abstract

The invention discloses a method for indicating a message type. The method comprises the following steps that a message type identifier is added in transmitted control plane signaling information; when a network node which receives the control plane signaling information determines that the control plane signaling information contains user plane data according to the message type identifier, the user plane data is transmitted to user equipment, other network nodes or an MTC (machine type communication) server through the control plane signaling information; the user equipment or the MTC server judges whether the control plane signaling information contains the user plane data or not; and when the control plane signaling information contains the user plane data, the user plane data is parsed from the control plane signaling information. The invention additionally provides a system and a device for indicating the message type. By adopting the technical scheme, the problem that the user plane data is lost when the control plane signaling information contains the user plane data can be solved.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a message type indicating method, system and device. Background technique [0002] Machine-to-machine (M2M, Machine to Machine) refers to all technologies and means for establishing connections between machines. The concept of M2M appeared in the 1990s, but it only stayed at the theoretical stage. After 2000, with the development of mobile communication technology, it became possible to realize the networking of machines and equipment with mobile communication technology. M2M services appeared in the market around 2002, and developed rapidly in the following years, becoming the focus of attention of many communication equipment manufacturers and telecom operators. At present, the number of machines in the world is much larger than the number of people, so it is foreseeable that the M2M technology will have a good market prospect. [0003] Research on M2M communication ...
