Problems solved by technology

[0003] In the data transmission method provided above, since the data needs to be forwarded by the application server during the data transmission process, a handshake process is often required between the terminal and the application server to maintain the communication connection, which brings huge Network Signaling Burden

Embodiment Construction

[0032] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0033] Under normal circumstances, because the IP address of the terminal is allocated dynamically and is not fixed, for example, the gateway device will re-allocate the IP address every time the terminal accesses the mobile communication network, so users cannot know each other If there is no IP address information, the terminals cannot directly transmit data. However, since the terminal ident...

Abstract

The invention relates to a data transmission method, network equipment and a terminal, and belongs to the technical field of communication. The data transmission method comprises the following steps: receiving an inquiry request sent by a second terminal; acquiring address information of a first terminal from a pre-stored corresponding relationship among a terminal identifier, an application identifier and the address information according to a terminal identifier of the first terminal and the application identifier of an application; and transmitting the address information of the first terminal to the second terminal. The inquiry request carrying the terminal identifier of the first terminal and the application identifier sent by the second terminal is received, and the address information of the first terminal is determined and returned according to the pre-stored corresponding relationship among the terminal identifier, the application identifier and the address information, so that the second terminal can directly transmit data to the first terminal according to the address information of the first terminal; a handshake flow needing to be performed frequently between the second terminal and an application server is avoided; and the network signaling burden is lowered.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, network equipment and a terminal. Background technique [0002] With the rapid development of communication technology, mobile communication services have gradually become mainstream. A mobile communication network mainly includes a circuit domain and a data domain. The circuit domain is usually used to transmit voice services, and the data domain is usually used to transmit data services. When the terminal performs data service communication, the gateway device in the data domain assigns an IP (Internet Protocol, Internet Protocol) address to the terminal. However, since the terminals cannot obtain each other's IP addresses, a data communication connection cannot be directly established. Usually, the data transmission between terminals needs to rely on the application server, that is, the terminal side starts the network application, se...
