Embodiment 1

[0137] The network structure of the system used for IP small data packet transmission in the embodiment of the present invention is as follows image 3 As shown, it may include UE, eNodeB, MME, MTC-IWF, SGW / PGW, and MTC AS. MME communicates with MTC-IWF through T5 interface, MME communicates with SGW / PGW through S11 interface, and SGW / PGW communicates with A new S11sd interface is added between MTC-IWF to realize communication. Wherein, a binding relationship is established between the PGW and the MTC-IWF, so that the MTC-IWF of the same UE and the allocated PGW can know each other. In this way, a NAS-based signaling plane data transmission channel can be established between the UE and MTC-IWF, and the MTC-IWF can forward the IP small data packets sent by the UE through the NAS-based signaling plane data transmission channel to the PGW, and the PGW After receiving the small IP data packet sent to UE, it can be sent to MTC-IWF through the NAS-based signaling plane data transmi...

Embodiment 2

[0201] The network structure of the system used for IP small data packet transmission in the embodiment of the present invention is as follows Figure 7 As shown, it is an enhancement to the existing SAE architecture, the PGW includes the functions of the SGW, and its composition structure is the same as that in Embodiment 1 image 3 The network structures shown are basically the same, the difference is that there is no binding relationship between PGW and MTC-IWF, but there is a binding relationship between MME and SGW / PGW, and the enhanced S11sd interface communication, the transmission of IP small data packets can be realized on the enhanced S 11sd interface.

[0202] Such as Figure 8 As shown, the process of transmitting IP small packets in the present embodiment may include the following steps:

[0203] Step 801: Establish a control plane transmission channel between the PGW and the MME to realize the transmission of IP data packets;

[0204] Step 802: The MME receive...

Embodiment 3

[0218] During the transmission of downlink IP data packets, the PGW needs to first judge whether to use the data transmission method of carrying IP data on the control plane based on the following factors: 1) whether the received downlink IP data packets are IP small data packets; The UE transmits small IP data packets by means of carrying IP data on the control plane. Whether the PGW has established a control plane data transmission channel with the MTC-IWF / MME, or whether the MME has instructed the UE to use the data transmission mode of the control plane carrying IP data;

[0219] On the PGW, the following filtering rules can be installed for the downlink IP data packet: when receiving the downlink IP data packet, judge whether it is a small IP data packet, and use the control plane data transmission between PGW and MTC-IWF / MME The channel delivers IP small packets.

[0220] Here, when the size of the IP data packet is smaller than the preset normal IP data packet size, th...

Abstract

The invention discloses an IP small data pack transmission method. The method comprises the steps that a control plane transmission channel between a PGW and an MTC-IWF network element is built, or a control plane transmission channel between the PGW and an MME is built; IP small data packs are transmitted through the control plane transmission channel between the PGW and the MTC-IWF network element or through the control plane transmission channel between the PGW and the MME. Correspondingly, the invention discloses an IP small data pack transmission system. IP small data pack transmission between UE and AS is realized without user plane connection of the UE and GCSN / PGW, the method and system can be widely applied to various network scenes, and when small-data-amount IP data packs are processed, signaling cost can be lowered, processing efficiency is improved, and network load is lowered.

Description

technical field [0001] The invention relates to the field of IP data transmission, in particular to a method and system for transmitting IP small data packets in the field of Machine Type Communication (MTC, Machine Type Communication). Background technique [0002] MTC is a mutual communication method between terminal devices. Unlike ordinary communication, where the two ends are people to people, the two ends of MTC communication are terminals or servers, such as communication between terminals and servers, communication between terminals and terminals, etc. An MTC terminal is a kind of user equipment (UE, User Equipment) capable of MTC. Most of the MTCs are based on IP access, and in the MTC, communication between terminals and between terminals and servers is realized through IP connection. [0003] The network architecture of the communication between the MTC terminal and the MTC application server (MTC AS, MTC Application Server) is as follows: figure 1 As shown, the...
