Embodiment Construction

[0066] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0067] see figure 1 , which shows a structure diagram of a data transmission system, the data transmission system includes a session initiating terminal, a first session border controller (SBC), an IMS network, a second session border controller (SBC) and a session receiving terminal.

[0068] The session initiating terminal (UE_A) is a terminal in the enterprise intranet. The session initiating terminal can be a terminal with network connection functions such as a smart phone, a personal computer, and a tablet computer. In order to protect the security of the enterprise network, the session initiating terminal is connected to The network is usually in a restricted state, only allowing session initiating terminals to access ports 53, 8...

Abstract

The invention discloses a session border controller and a data transmission method and belongs to the technical field of Internet. The method comprises the following steps that a data through layer receives a to-be-transmitted data packet, which is sent by a session initiation terminal through a first designated port when, under a restricted network and sends the information of the to-be-transmitted data packet and the first designated port to a data processing layer; the data processing layer receives the information of the to-be-transmitted data packet and the first designated port, stores a mapping relation between the information of the first designated port and the information of the data through layer and sends the to-be-transmitted data packet to a data transmission layer; and the data transmission layer receives the to-be-transmitted data packet and sends the to-be-transmitted data packet to an external network, and the external network sends the to-be-transmitted data packet to a session receiving terminal. According to the session border controller and the data transmission method, third-party equipment is not needed, and the data through layer initiates the terminal transmission data packet for a session under the restricted network, so that the flow consumption of a data transmission process is reduced, the data transmission delay is reduced and the timeliness of the data is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a session border controller and a data transmission method. Background technique [0002] With the development of Internet technology, network security has become a major issue affecting national security, social stability, and economic development. In order to ensure network security within the enterprise, more and more companies set up network devices such as NAT (Network Address Translation, Network Address Translation) and firewalls within the enterprise to strictly limit the ports accessed by terminals within the enterprise, for example, only allowing Terminals access ports 53, 80, 433, etc. In this network-restricted scenario, when an enterprise terminal needs to communicate with other terminals in the external network, how to perform data transmission has become a problem that people in the field pay more attention to. [0003] In the field of Internet technology, S...
