Embodiment 1

[0033] Such as image 3 As shown, it is a schematic diagram of the architecture of the communication system based on the security gateway in Embodiment 1 of the present invention. image 3 In the system architecture shown, the communication terminal accesses the home base station through the air interface; a secure tunnel is established between the home base station and the security gateway, and the security tunnel can be used for communication; the security gateway is independent of the system gateway, and the security gateway uses a proprietary transmission The line is connected to the system gateway; the system gateway is connected to the core network through the switch.

[0034] The system architecture is described in detail below:

[0035] Take femtocell 1 and femtocell 2 in broadband standard 1 connecting to security gateway 1 in broadband standard 1, femtocell 3 and femtocell 4 in broadband standard 2 to access security gateway 2 in broadband standard 2 as an example. ...

Embodiment 2

[0046] Assuming that the broadband standard of the security gateway in the second embodiment and the third embodiment is the same as the broadband standard of each home base station that has established a security tunnel with the security gateway, it is avoided that when the home base station accesses a security gateway of a different broadband standard, the The communication data packets transmitted by the home base station need to pass through multiple devices to reach the security gateways of different broadband standards, aggravating the problems of communication data packet delay and packet loss.

[0047] Such as Figure 4 As shown, it is a schematic diagram of the steps of the communication method based on the security gateway in Embodiment 2 of the present invention, and the method mainly includes the following steps:

[0048] Step 101: the security gateway receives the communication data packet sent by the source communication terminal through the accessed source home ...

Embodiment 3

[0058] Such as Figure 5 As shown, it is a schematic diagram of the steps of the communication method based on the security gateway in the third embodiment of the present invention, and the method mainly includes the following steps:

[0059] Step 201: The security gateway receives the communication link information sent by the core network.

[0060] The communication link information is generated by the core network when a communication link is established between the source communication terminal and the target communication terminal, and the communication link information includes the source communication terminal identifier, the source home base station identifier, the target communication terminal identifier, and Target Femtocell ID.

[0061] Take the voice call service between the source communication terminal (called UE1) and the target communication terminal (called UE2) as an example, assuming that UE1 is the calling terminal, accessing the source home base station, ...

Abstract

The invention discloses communication method, system and equipment based on a security gateway. The communication method, system and equipment is mainly characterized in that the security gateway is independent of a system gateway; when a source home base station and a target home base station are in the same security gateway, communication data packets are transmitted from the source home base station to the target home base station through the security gateway instead of the system gateway and a core network. Therefore, the system gateway and the core network are not required in the transmission process of partial communication data packets in communication services, and service pressure is reduced greatly for the system gateway and the core network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, system and equipment based on a security gateway. Background technique [0002] With the continuous increase of users' demands on communication resources, a femto system based on femtocells emerges as the times require. In the femto system, the home base station is connected to the mobile core network through the fixed network broadband, which greatly expands the coverage of mobile communication signals, so that the communication terminals connected to the home base station can perform daily communication well. [0003] Such as figure 1 As shown, it is a schematic diagram of the traditional femto system architecture, from figure 1 It can be seen from the figure that the communication terminal accesses the femtocell through the air interface, the security gateway module with IPSec (Internet Protocol Security, Internet Protocol Security) capa...
