Embodiment 1

[0035] see figure 2 , which is a schematic diagram of the network structure of Embodiment 1 of the present invention. In this embodiment, the network elements involved are:

[0036] (1) UE (User Terminal) is a terminal device that initiates a service request, including various mobile phone terminals, smart terminals, and other information communication terminal devices accessed by wired or wireless methods.

[0037] (2) AG (Access Gateway), which transmits user data to a network carrying service applications (such as a TCP / IP network or an X.25 network) to realize intercommunication between the access network and the network carrying service applications. AG can be GGSN, AC, ADSL, DSLAM, BRAS and so on.

[0038] (3) AN (Access Network), which is a network between UE and AG and provides access service for UE, including wireless access network and wired access network.

[0039] (4) Service Gateway (SG for short): According to the objects served, SG can be roughly divided into...

Embodiment 2

[0070] see image 3 As shown, it is a signaling flow chart of Embodiment 2 of the present invention. This embodiment describes the flow of user terminals accessing public data services:

[0071] Step 1a, the user terminal (UE) sends a service request packet to the AG device to access the public service application server.

[0072] Step 1b: The AG device finds that the service request is an access to a public service, and the AG device sends the data packet to the PE device corresponding to the user domain through dedicated line or tunnel encapsulation.

[0073] Step 1c, the PE device on the user side sends the data packet to the PE device on the PSG side through the VPN where the user is located in the IP private network.

[0074] In step 1d, the PE device on the PSG side forwards the data packet to the PSG device corresponding to the user.

[0075] In step 1e, the PSG device performs operations such as protocol conversion and user ID insertion.

[0076] Step 1f, the PSG de...

Embodiment 3

[0085] see Figure 4 As shown, it is a signaling flow chart of Embodiment 3 of the present invention. This embodiment describes the process of user terminal accessing its own data service:

[0086] Step 2a, the user terminal (UE) sends a service request data packet for accessing its own service platform to the AG device.

[0087] Step 2b: The AG device finds that the service request is an access to its own service, and the AG device sends the data packet to the PE device corresponding to the user domain through methods such as dedicated line or tunnel encapsulation.

[0088] Step 2c, the PE device on the user side sends the data packet to the PE device on the SSG side through the VPN where the user is located in the IP bearer network.

[0089] Step 2d, the PE device on the SSG side forwards the data packet to the SSG device that the user requests to access. So far, the UE has established a connection with the SSG device.

[0090] Step 2e, the SSG device receives the user se...

Abstract

The invention discloses a data service network system as well as an access method of data services, and the system comprises: an access gateway, a service gateway, a first border router which is connected with the access gateway for converging and classifying a user data flow and transmitting the user data to a second border router via virtual private network; and the second border router which is connected with the service gateway and connected with the first border router via the virtual private network for transmitting the user data to the service gateway. In the technical proposal, the service flow does not pass through a GRE tunnel for encapsulation and decapsulation due to the introduction of VPN in IP bearer network, thereby breaking through limitations of GRE encapsulation efficiency and bandwidth and eliminating the performance bottleneck problem of the whole network brought by NAT conversion.

Description

technical field [0001] The invention relates to a network system and a method for accessing data services, in particular to a network system for processing self-owned data services and public data services and a method for accessing data services, belonging to the field of communication technology. Background technique [0002] Today, with the rapid development of science and technology, network technology is also undergoing rapid changes. Nowadays, the network provides users with a variety of rich and colorful data services, and users can access the network anytime and anywhere to query the required information. However, with the continuous development of network technology, users hope to obtain more resources and access more services from the network in more colorful forms. [0003] figure 1 As shown in , it is a schematic structural diagram of a data service network system in the prior art, mainly including: [0004] User Equipment (UE for short) is a terminal device t...
