Problems solved by technology

Therefore, it is impossible to access terminal services by configuring a unified WAP gateway address in the WAP terminal. How to configure the IPv6 address of the WAP gateway to the user terminal and ensure that the user can correctly use the WAP service when roaming becomes a problem.
At the same time, in the existing solution, the GGSN and the WAP gateway need to forward data packets through the GRE tunnel, which reduces the efficiency of data packet forwarding and increases the complexity of networking and the difficulty of operation and maintenance.

Embodiment 1

[0037] Embodiment 1 of the present invention provides a method for configuring a WAP gateway IP address, which is applied to a 2G / 3G network or an LTE network. The method is as follows: figure 1 shown, including the following steps:

[0038] Step 101, the network side assigns the WAP gateway IP address to the WAP terminal, and sends the WAP gateway IP address to the WAP terminal;

[0039] Step 102, the WAP terminal configures the IP address of the WAP gateway according to the IP address of the WAP gateway;

[0040] Wherein, the network side may send the WAP gateway IP address to the WAP terminal through the PDP (Packet Data Protocol, packet data protocol) context activation process, or through the attach process, or through the RA message, or according to the DHCP process initiated by the WAP terminal.

[0041] Through the WAP gateway IP address configuration method provided by the embodiment of the present invention, the WAP terminal does not need to pre-configure the IP add...

Embodiment 2

[0044] figure 2 Provided a kind of WAP gateway IP address configuration method that the second embodiment of the present invention proposes, present embodiment is described with 2 / 3G system, comprises WAP terminal, SGSN (Service GPRSSupport Node, service GPRS support node) in the system, GGSN, Authentication server (Radius), WAP GW and business platform, this method is as follows figure 2 shown, including the following steps:

[0045] In step 201, the WAP terminal initiates a connection request to the SGSN, and the connection request may be a PDP activation request.

[0046] Step 202, SGSN forwards the connection request to GGSN;

[0047] Specifically, the SGSN requests domain name resolution from the DNS (DomainName System, Domain Name System) in the GPRS (General Packet Radio Service, General Packet Radio Service) network according to the APN provided by the user terminal when sending the PDP context activation request, and obtains the IP address of the GGSN , and forwa...

Embodiment 3

[0068] The embodiment of the present invention describes that after the GGSN assigns the IP address prefix and the interface ID to the WAP terminal, it notifies the WAP terminal of the IP address of the WAP gateway through other messages. Based on the same communication system as in Embodiment 2, Embodiment 3 of the present invention proposes a method for configuring a WAP gateway IP address, such as Figure 3.a shown, including the following steps:

[0069] Steps 301-308, and figure 2 Steps 201-208 of the flow shown are the same or similar.

[0070] In step 309, the GGSN sends the IPv6 address prefix and interface identifier assigned to the WAP terminal to the WAP terminal.

[0071] In step 310, the WAP terminal can optionally initiate an RS message to request the GGSN to allocate an IPv6 global unicast prefix for it. This step is optional.

[0072] Step 311 , the GGSN sends an RA message to the WAP terminal, and the RA message carries the IP address of the WAP gateway; ...

Abstract

The invention discloses an IP (Internet Protocol) address configuration method of a WAP (Wireless Application Protocol) gateway and equipment thereof. The method comprises the following steps that: a network side distributes the IP address of the WAP gateway for a WAP terminal and sends the IP address of the WAP gateway to the WAP terminal; and the WAP terminal carries out the configuration for the IP address of the WAP gateway according to the IP address of the WAP gateway. According to the technical scheme, the WAP terminal does not configure the IP address of the WAP gateway in advance; when a user terminal uses a WAP business and after the network side selects the WAP gateway, the IP address of the WAP gateway is sent to the WAP terminal through a notification message; and after the WAP terminal receives the IP address of the WAP gateway, the WAP terminal carries out the configuration for the IP address of the WAP gateway, so that the WAP terminal carries out the configuration for the IP address of the WAP gateway during the WAP business access.

Description

technical field [0001] The invention relates to the communication field, in particular to a WAP gateway IP address configuration method and equipment thereof. Background technique [0002] Currently, the WAP GW (Wireless Application Protocol Gateway, wireless application protocol gateway) is uniformly configured as a private address of 10.0.0.172, and this address is also configured in the wireless user terminal by default. When the user terminal obtains an IP address and accesses the Internet, the user data packet is encapsulated by the GGSN (Gateway GPRSSupport Node, gateway GPRS support node) into the GRE (Generic Route Encapsulation, general routing encapsulation) tunnel to reach the WAP GW, and the WAP GW is responsible for address translation or Acting as a user to access the business platform. When the user roams, the address of the WAP GW on the terminal does not need to be changed, and the GGSN selects the WAP GW of the visited or home location according to the APN...
