Embodiment Construction

[0050] (1) LTE (Long Term Evolution, long-term evolution) system structure

[0051] Such as figure 1 As shown, it is a schematic diagram of the network architecture of the LTE system. In order to facilitate the development of new services, the design method of separating the user plane and the control plane is adopted in the LTE system. Among them, the control plane signaling and user plane bearer in the core network corresponding to the LTE system are respectively responsible for independent network elements MME (Mobility Management Entity, Mobility Management Entity) and S-GW (Serving Gateway, Serving Gateway).

[0052] Specifically, the main functions of the MME include NAS (Non Access Stratum, non-access stratum) signaling establishment, NAS signaling security, cross-core network signaling establishment, tracking service (when LIE is in IDLE mode), roaming service, Authorization and bearer management, etc.

[0053] S-GW is the gateway point for eNB (base station) switchi...

Abstract

The invention discloses a transmission method of data and equipment. The method comprises the following steps that: access network equipment receives an empty message from user equipment (UE), wherein the empty message carries a non access stratum (NAS) message and the NAS message carries user data; the access network equipment obtains the NAS message from the empty message and adds the NAS message into an interface message; and the access network equipment sends the interface message to core network equipment. According to the embodiment of the invention, user data with a small data volume are transmitted by connection of control planes, so that signaling that is needed to establish and maintain connection of user planes can be reduced, signaling costs are reduced and system efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique [0002] M2M (Machine-to-machine, machine-to-machine) communication, also known as MTC (Machine Type Communication, machine type communication) communication, as a new type of communication concept, its purpose is to organically combine various types of communication technologies (such as : machine-to-machine communication, machine control communication, human-computer interaction communication, mobile Internet communication, etc.), thereby promoting the development of social production and lifestyle. [0003] Among them, the current mobile communication network is designed for communication between people (such as: the determination of network capacity, etc.), if you want to use the current mobile communication network to support M2M communication, you need to make a The mechanism of the communication...
