Embodiment 1

[0063] The method for user equipment accessing the Internet provided by Embodiment 1 of the present invention can reduce core network traffic, reduce time delay, save cost, and reduce investment. At the same time, it can facilitate legal monitoring and charging of bypass traffic.

[0064] like image 3 As shown, the specific steps of the method include:

[0065] S301, UE (User Equipment, user equipment) sends an attach request message to SGSN (Serving GPRS Support Node, serving general packet radio service support node), and initiates an attach process;

[0066] S302. The SGSN returns an Attach Accept message to the UE;

[0067] S303. When the UE has a service to initiate, send an activation PDP (Packet Data Protocol, packet data protocol) context request message to the AG (Access Gateway, Access Gateway);

[0068] S304, the AG judges whether the APN (Access Point Name, access point name) in the activation PDP context request message is the APN of the general flow control in...

Embodiment 2

[0104] The method for the user equipment to access the Internet provided by the second embodiment of the present invention can reduce the traffic of the core network, reduce the time delay, save the cost and reduce the investment, and at the same time, can facilitate legal monitoring and charging of the bypass traffic.

[0105] like Figure 4 As shown, the specific steps of the method include:

[0106] S401. The UE sends a PDP context activation request to the AG;

[0107] S402, AG determines whether the APN in the activation PDP context request message is the APN of the Gi interface service, if not, directly transparently transmits the activation PDP context request message, and performs a normal PDP context activation process, that is, the AG transparently transmits the activation request to the SGSN , the SGSN initiates a PDP context creation request to the GGSN, and the CN (Core Network, core network) allocates an IP address for the Gi interface service to the UE, and ret...

Embodiment 3

[0134] The method for user equipment accessing the Internet provided by Embodiment 3 of the present invention can reduce core network traffic, reduce time delay, save cost, and reduce investment. At the same time, it can facilitate legal monitoring and charging of bypass traffic.

[0135] like Figure 5 As shown, the specific steps of the method include:

[0136] S501. The UE sends a PDP context activation request to the AG;

[0137] S502, the AG judges whether the APN in the activation PDP context request message is the APN of the Gi interface service, if not, directly transparently transmits the activation PDP context request message, and performs the normal PDP context activation process; if yes, then marks the PDP context as PDP context used by Gi interface services;

[0138] S503, the AG forwards the activation PDP context request message to the SGSN;

[0139] S504. The SGSN sends a request to create a PDP context to the GGSN;

[0140] S505, the CN assigns the IP addr...

Abstract

The invention discloses a method for accessing internet by user equipment and a system therefor and relates to the communication field for solving the problems of convenient lawful interception and billing by directly accessing the internet through an access gateway. The invention adopts the solution that: the access gateway AG receives the activated packet data protocol PDP context request message sent by the user equipment UE and the AG is in the activated state; the AG differentiates the received business flow of the UE; and if the business flow of the UE is the flow of a Gi interface, theAG forwards the flow of the Gi interface to the internet. The invention is used for accessing the internet by the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for user equipment to access the Internet. Background technique [0002] AP (Access Point, Access Point) is a network device that provides wireless access services for families / enterprises based on a fixed IP transmission network. [0003] AP networking such as figure 1 shown. UE (User Equipment, user equipment) accesses the access point through the air interface, and the access point accesses the IP transmission network through the HGW (Home Gateway, home gateway) (the access point may be integrated with the home gateway), and then connects through the IP transmission network Go to the SeGW (Security Gateway, security gateway) in the mobile core network, and then connect to the AG (Access Gateway, access gateway) (the access gateway may integrate a security gateway). The access gateway is then connected to the CS domain core network and the PS domain core...
