[0114] Such as figure 2 As shown, the data transfer method includes:

[0115] Step 21, obtaining a trigger instruction;

[0116] Step 22, assigning an IP address to the terminal according to the trigger instruction;

[0117] Step 23, establishing a data connection between the terminal and an external packet data network;

[0118] Step 24, based on the data connection and the IP address, perform data transmission between the terminal and an external packet data network.

[0119] This embodiment enables the base station to transmit the service flow data of the terminal to the external data network according to the IP address assigned by the base station to the terminal, and also transmit the service flow data of the external data network to the destination terminal, and can reduce the forwarding of service flow data path, thereby reducing the delay of service flow data transmission and improving the efficiency of service flow data transmission, meeting the requirements of lo...

[0121] Data transfer methods include:

[0122] Step 211, acquiring the trigger instruction sent by the mobility management entity MME according to the identifier of the terminal;

[0123] Step 22, assigning an IP address to the terminal according to the trigger instruction;

[0124] Step 23, establishing a data connection between the terminal and an external packet data network;

[0125] Step 24, based on the data connection and the IP address, perform data transmission between the terminal and an external packet data network.

[0126] Combine below image 3 The flow shown illustrates the specific implementation process of the above step 211:

[0127] Step 2111, acquiring a trigger instruction sent by the MME according to the terminal's subscription information, wherein the subscription information includes the terminal's identifier; or

[0128] Step 2112, acquiring a trigger instruction sent by the MME according to the service indication information of the terminal, where...

[0136] Data transfer methods include:

[0137] Step 211, obtain a trigger instruction;

[0138] Step 222, dynamically assigning an IP address to the terminal according to the trigger instruction; or

[0139] Step 223, the triggering instruction includes: a static IP address; obtaining the static IP address in the triggering instruction; assigning the static IP address to the terminal;

[0140] Step 23, establishing a data connection between the terminal and an external packet data network;

[0141] Step 24, based on the data connection and the IP address, perform data transmission between the terminal and an external packet data network.

[0142] The trigger instruction in the above embodiment can be as follows image 3 Step 5 shown in : the session creation request sent by the MME to the base station, of course, may also be a new message sent by the MME to the base station, and the new message includes an indication of the identity of the terminal.

Abstract

The present invention provides a data transmission method, a base station, a mobile management entity, a terminal and a system, which relate to the communication field and are invented to solve the problem that the data transmission process in the prior art cannot meet the data transmission requirements of the terminal. The data transmission method includes: acquiring a trigger instruction; assigning an IP address to the terminal according to the trigger instruction; establishing a data connection between the terminal and an external packet data network; for data transfer. The solution of the present invention can transmit the service flow data of the terminal to the external data network, and can also transmit the service flow data of the external data network to the destination terminal, and can reduce the forwarding path of the service flow data, thereby reducing the time of service flow data transmission. Yanhe improves the efficiency of business flow data transmission and meets the requirements of low power loss and low complexity for data transmission of massive terminals.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular refers to a data transmission method, a base station, a mobility management entity, a terminal and a system. Background technique [0002] As the core network of the LTE (Long Term Evolution) system, SAE (System Architecture Evolution) is a pure packet domain network on which data services are carried. [0003] As a network layer protocol, IP has been fully developed and widely used. Therefore, SAE network also adopts IP as the network layer protocol of its underlying transmission network. [0004] SAE is an all-IP network, and each physical entity of the control plane and the user plane supports IP transmission. [0005] Compared with the traditional 2G / 3G core network, the SAE network separates the control plane and the user plane, and provides different management methods for signaling and data transmission and communication, which makes the core network and ac...
