In a WAP gateway provided by an embodiment of the present invention, when the GGSN corresponding to the NET access point encapsulates the first data packet received from the user equipment through the NET access point according to the preset encapsulation technology to obtain the second data packet, receiving the second data packet sent by the GGSN; and for the first data packet; wherein, the first data packet contains a request message for the user equipment to access the WEB server and the GGSN is the An Internet Protocol IP address assigned by the user equipment; decapsulating the received second data packet to obtain the first data packet; sending the first data packet to the WEB server.

In order to enable those skilled in the art to understand the technical solution provided by the present invention more clearly, the technical solution provided by the present invention will be described in detail below through specific examples:

In the following specific embodiments, as shown in Figure 6, the following steps are included:

Step 1. Taking the GGSN connected by the user equipment as the unit, select the GGSN-NET that needs to be offloaded according to the distribution of the user equipment and the NET traffic load, and connect the NET traffic of the GGSN-NET that needs to be offloaded to the WAP gateway for NET traffic offloading .

Step 2. Unified planning is made for the IP address segment used by the GGSN-NET and the IP address segment used by the GGSN-WAP, so that the IP address segment used by the GGSN-NET and the IP address segment used by the GGSN-WAP do not overlap.

Step 3, select the GRE tunnel connection mode between GGSN-NET and WAP gateway;

Exemplarily, for example, as shown in FIG. 7 .

Step 4. Encapsulate the private IP data packet sent to GGSN-NET when the user equipment accesses the network through the NET access point. After the GGSN encapsulates the private IP data packet of the user equipment and transmits it to the WAP gateway through the GRE tunnel, the WAP gateway The encapsulated data packet is analyzed to obtain the private IP data packet sent by the user equipment to the GGSN-NET.

Among them, in the WAP access environment of the existing network, only the GGSN-WAP address pool is connected to the WAP gateway, and there is no connection between the GGSN-NET address pool and the WAP gateway.

Specifically, in order to introduce NET traffic into the WAP gateway, the key is to establish a GRE tunnel between the GGSN-NET and the WAP gateway.

The purpose of establishing a GRE tunnel is twofold:

(1) Change the routing method of NET traffic, encapsulate the data packets originally accessed by the user equipment to the WEB server through the GRE tunnel, GGSN-NET only needs to transmit the data packets to the WAP gateway through the GRE tunnel, and the WAP gateway parses the data packets , obtain the IP address of the WEB server that the user equipment needs to access, and then route and forward the data packet;

(2) Since GGSN-WAP and GGSN-NET are originally independent services, the IP address pools of the two types of services are allowed to be reused each other, so if the NET traffic is directly introduced into the WAP gateway, it will cause WAP users inside the WAP gateway and If the IP addresses of NET users conflict, the GGSN-NET is connected to the WAP gateway through the GRE tunnel, so that the IP addresses of NET users are transparent to the WAP gateway, and there will be no conflict between the IP addresses of NET users and WAP users. After the WAP gateway receives the service request of the NET user, it analyzes the data packet and distributes it to the corresponding WEB server. The data packet needs to be encapsulated and returned to the GGSN-NET through the GRE tunnel, and then returned to the user equipment by the GGSN-NET. Remote user dial-in authentication service request (RemoteAuthenticationDialInUserServiceRequest, RadiusRequest) message (this message is included in the data packet sent by GGSN-NET to the WAP gateway)

Step 5, the WAP gateway receives from the GGSN-NET end the request message that contains the user equipment to access the WEB server, the content of the RadiusRequest message includes the IP address and the MSISDN of the user equipment, and the WAP gateway is responsible for maintaining the IP address and the MSISDN of the user equipment during the session. Correspondence between MSISDN numbers. The WAP gateway routes and forwards the MSISDN number of the user equipment to the marketing server. The marketing server identifies the user through the MSISDN. According to the MSISDN, the unique identification field, obtains the relevant information of the user equipment from the operator's BSS, which may include but not limited to the following fields:

1 remaining credit 5 contract expiration date 2 residual flow 6 User type (2G/3G/4G) 3 remaining talk time 7 User terminal model 4 Remaining number of text messages 8 Latest event information

Step 6. The marketing server generates marketing information according to the acquired information about the user equipment and returns the marketing information to the WAP gateway.

Specifically, combined with the above table in step 5, there can be 3 situations:

(1) Thresholds are set within the marketing server for user charges, traffic, calls, short messages, and contract expiration dates. When the user billing information obtained from the BSS domain triggers the threshold, the marketing server generates a notification message and returns the notification message to WAP gateway.

(2) When there is a new promotional activity, the marketing server returns the promotional activity information to the WAP gateway.

(3) For 2G and 3G users, as well as users with old terminals, return push messages for encouraging users to upgrade network standards and update smart phones to the WAP gateway.

Step 7. After the WAP gateway receives the data packet of the user equipment from the GGSN-NET end, it analyzes the data packet, routes and forwards the service request of the user equipment to access the WEB server to the corresponding WEB server, and the WEB server returns a response after receiving the request message to the WAP gateway.

Step 8. After the WAP gateway receives the response message returned by the WEB server and the marketing message returned by the marketing server, it will combine the two parts of the message, and the WAP gateway will include the combined message in the data packet and send the corresponding GGSN- NET.

Step 9, GGSN-NET receives the data packet sent by the WAP gateway, analyzes the encapsulated message to obtain the combined message of the WAP gateway, and then forwards it to the corresponding user equipment, so that the user equipment of the NET access point passes through the WAP gateway Access to the WEB server, in addition, because there is marketing information for the user equipment in the returned message, it can help the operator to achieve a certain degree of marketing promotion.

Although the embodiments disclosed in the present invention are as above, the described content is only an embodiment adopted for understanding the present invention, and is not intended to limit the present invention. Anyone skilled in the field of the present invention can make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the patent protection scope of the present invention must still be The scope defined by the appended claims shall prevail.
