Embodiment 1

[0037] see figure 1 , this embodiment provides a method for transmitting data, the method comprising:

[0038] 101: Obtain transmission indication information of the user equipment, and receive uplink service data sent by the user equipment through uplink control plane signaling, where the transmission indication information is used to indicate transmission of service data through control plane signaling;

[0039] Wherein, the transmission indication information includes: at least one of: indication of low data volume transmission, indication of using control plane transmission, service level, service characteristic and user subscription characteristic.

[0040] Wherein, the control plane signaling here refers to the air interface and access network control plane signaling between the user equipment and the mobility management entity.

[0041] 102: Send the uplink service data to the server through the core network gateway entity according to the transmission instruction info...

Embodiment 2

[0044] This embodiment provides a method for transmitting data through complete control plane signaling. Specifically, the following three methods may be used for data transmission.

[0045] Method 1: see figure 2 , the UE sends a normal attach message before accessing. According to the obtained subscription data, the MME judges that the service should use the control plane signaling to transmit data, sends a message to the UE indicating the transmission mode, and then triggers each node on the network side to encapsulate the data in the control plane signaling message for transmission. The method specifically includes:

[0046] Step 201. The UE initiates an attach process, and sends an attach request message to the eNodeB (evolved Node B, evolved base station) through NAS (Non Access Stratum, non-access stratum) signaling;

[0047] Among them, the attach request message contains NAS-related parameters, including IMSI (International Mobile Subscriber Identity, International...

Embodiment 3

[0129] see Figure 5 This embodiment provides a method for activating a UE in an Idle (idle) state initiated by a user side and transmitting data through control plane signaling.

[0130] After the UE establishes a connection with the network through an attach request and sends data, each relevant node in the network stores the context and required information of the UE. In the following time, the UE and the network side can also perform data transmission as needed. At the same time, if the UE does not transmit data for a period of time, the Timer (timer) on the eNodeB may expire through the existing method and notify the MME or pass the MME Methods such as direct discovery turn the UE into the Idle state. At this time, the relevant context of the UE on the eNodeB will be deleted, and the air interface connection will be released. The UE thus becomes the Idle state. If the UE in the Idle state needs to interact with the network to transmit data, it needs to be converted to t...

Abstract

The invention discloses a method, equipment and a system for transmitting data, which belongs to the field of wireless communication. The method comprises the following steps of: acquiring transmission indication information of user equipment and receiving uplink service data transmitted by the user equipment through an uplink control plane signaling, wherein the transmission indication information is used for indicating to transmit service data through a control plane signaling; and according to the transmission indication information, transmitting the uplink service data to a server through a core network gateway entity. The equipment comprises an acquisition module and an uplink transmission module. The system comprises a mobile management entity, a server connected with the mobile management entity in a communication mode, and the user equipment. The method, the equipment and the system save network resources and reduce data transmission time compared with the prior art.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for transmitting data. Background technique [0002] M2M (Machine to Machine, machine-to-machine) communication, or MTC (Machine Type Communications, machine type communication), is a communication method for data transmission between machines through a wireless communication system. [0003] Taking the M2M service of the LTE (Long Term Evolution, long-term evolution) wireless communication system as an example, the specific process of UE (User Equipment, user equipment) attaching to the network is as follows: [0004] The UE sends an attach request message to the MME ((Mobility Management Entity, Mobility Management Network Element). If a new MME is attached, it needs to delete the old MME and the UE’s past bearer information that may be saved by the core network. The new MME needs to obtain from the HSS (Home Subscriber Server, home use...
