DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings. First, a process of accessing a webpage by a user equipment through a mobile network is described. The whole process is shown in FIG. 1. After the user inputs a web address/domain name through a browser interface on the UE, the domain name server (DNS) request is sent to the base station BS. The base station forwards the above DNS request to the gateway through a wireless network, such as a GGSN or other gateway, and sends the DNS request to the DNS server responsible for the domain name resolution service by the gateway connected to the Internet; the DNS server queries according to the DNS server The IP address corresponding to the domain name carried in the DNS request, and then responding, and returning the IP address to the user equipment through the gateway and the base station, and the browser on the user equipment generates an ultra according to the IP address carried in the DNS response. The Hypertext Transfer Protocol (Http) request is forwarded to the http server as the web server through the base station and the gateway layer, and accesses the web page corresponding to the IP address.

In the embodiment of the present invention, the user equipment UE includes, but is not limited to, a portable device such as a smart phone, a tablet computer, and a notebook computer.

The various requests sent by the user equipment to the gateway are forwarded by the base station, and the requests sent by the user equipment to the various servers are also forwarded by the base station and the gateway. Therefore, for the sake of brevity, the forwarding process is no longer described, and those skilled in the art It should be understood.

As shown in FIG. 2, an embodiment of the present invention provides a method for redirecting a user equipment to access a webpage, where the method is performed by a gateway, and the method includes:

201. Receive a data access request sent by a roaming user equipment UE.

Specifically, the user equipment is in a roaming state, that is, an operator in a location where the user is located is not an operator of the user equipment home. Therefore, the user equipment needs to go through the gateway of the roaming location to perform the data access request. In this embodiment, the data access request is a DNS request, where the website address of the website that the UE wants to access is carried, or It is a domain name, such as Sina, Google or Baidu. The UE wants to be able to obtain the IP address corresponding to the URL entered by the DNS server.

202. Search for a home location identifier of the UE. Specifically, the redirection policy is configured on the operator gateway of the roaming site. Before the user equipment browses the webpage, the user equipment needs to be redirected to the redirect page configured by the home operator for the user to refer to the information on the redirect page. , such as traffic, billing information and other data.

After receiving the DNS request sent by the user equipment, the gateway queries the home location information of the user equipment according to the local configuration, for example, the mobile subscriber international integrated service digital network number when the user equipment accesses the gateway (Mobile Subscriber International ISDN/PSTN number) , MSISDN) identifies several digits of the user equipment attribution, and determines the attribution of the user. For example, the MSISDN number of the user equipment A is 139010XXXXX. The first three digits 139 can be used to know that the user equipment A is a user of China Mobile. 010 out of 4-6 bits can know that the user equipment A is from Beijing.

203. Obtain a redirected uniform resource locator URL associated with the home location identifier for the UE according to the home location identifier of the UE.

Specifically, after the gateway queries the home location information of the user equipment, the gateway may generate a new redirect URL by using the local device, the software, or the external device to request the external device to send a new redirect URL. The URL contains the attribution information of the user equipment.

For example, the gateway can intercept the first 6 bits of the MSISDN of the user equipment A, carry it in the URL, generate a URL similar to 139010. Portal.cmcc.com, or configure the English name or pinyin name of the attribution name in the weight. Targeted URLs, such as Beijing.Portal.cmcc.com. Thus, in the DNS server configured with the IP address corresponding to the redirected URL, the IP address corresponding to the redirected URL can be obtained.

Note that the policy that the gateway redirects to the user equipment includes time limit or number of times. If it is time-limited, the user device only wants to access the Internet during roaming state for the first time in the week, or monthly. If the number of times is limited, the gateway only redirects when the user equipment accesses the Internet for the first time in the roaming. After the user sends the DNS request again, the gateway does not perform the redirection. 204. Send the redirected uniform resource locator to the user equipment.

Specifically, after the gateway generates the redirect URL for the UE, the gateway returns the packet carrying the redirected URL to the user equipment UE, and the browser of the user equipment generates a new packet after receiving the packet. DNS request, and forward the new DNS request to the DNS server through the gateway.

It should be noted that because the number of times or time policy is configured on the gateway, the gateway will not redirect the DNS request, but directly forward the new DNS request to the DNS server through the gateway. The DNS server queries and describes Redirecting the IP address corresponding to the URL, and returning the IP address to the user equipment, the user equipment generates an http request message according to the IP address, where the destination address is the IP address, and then sends the http request to the gateway through the gateway. After the web server of the web server is accessed, the webpage corresponding to the redirected URL is accessed, and the prompt data such as traffic and billing information is obtained. For the flow of the above embodiment, reference may be made to the interaction diagram shown in FIG.

After that, after browsing the page corresponding to the redirected URL, the user equipment may end browsing or select to continue accessing. If the user equipment wants to access the webpage, such as Sina, Baidu, etc. in the first data access request, the process may refer to the embodiment shown in FIG. 1, and therefore, the details are not described.

With the above embodiment, the user equipment can access the redirected webpage configured by the home gateway in the roaming state to obtain corresponding information.

In step 201 of the foregoing embodiment, the gateway receives the data access request sent by the user equipment UE as a DNS request, that is, when the user equipment is ready to access the Internet for the first time, the gateway redirects the user equipment.

In another embodiment, the gateway may also respond to the DNS request sent by the user equipment to the DNS server through the gateway, that is, the DNS server searches for and returns the domain name that the user equipment wants to access in the user equipment DNS request. After the IP address corresponding to the domain name, the user equipment generates an htt request message according to the IP address, and requests the gateway GGSN to HTTP. When the server forwards the http request packet, the gateway is triggered to redirect the user equipment.

The flow after the gateway is redirected to the user equipment is the same as step 202-step 204 in the embodiment shown in FIG. 2, and therefore will not be described again. The interaction diagram of this embodiment can be referred to FIG.

Step 501: Receive a DNS request sent by the user equipment UE, where the DNS request includes a redirected uniform resource locator URL, where the redirected URL carries the home location information of the UE; specifically, as shown in FIG. In the embodiment, after the gateway GGSN obtains the redirect URL for the user equipment UE, the user equipment generates a new DNS request, the DNS request message carries the redirect URL, and the redirect URL includes Destination information of the UE. Example ^ mouth, 139010. Portal.cmcc.com or Beijing .Portal.cmcc.com.

Step 502: Find an IP address corresponding to the redirected URL.

Specifically, the IP address corresponding data associated with the user equipment is stored locally on the DNS server or other device. For example, Beijing .Portal .cmcc.com and 139010. Portal.cmcc.com and 139012.Portal.cmcc.com and other gateways are associated with the same ip address 202.11.55. X. The user equipment of the IP address can access a webpage such as traffic statistics.

Step 503: Send the IP address to the user equipment.

Specifically, after obtaining the IP address corresponding to the redirected URL, the DNS server sends the DNS response packet including the IP address to the user equipment UE through the gateway and the base station, where the browser generates the destination address as described above. The hypertext transfer protocol of the IP address is an HTTP request message, and the HTTP request is sent to the HTTP server through the gateway, and the website corresponding to the redirected URL is accessed, and the redirected webpage of the home location is accessed in the roaming state to obtain the traffic. Billing and other information.

After the user equipment browses the page corresponding to the redirect URL, the user device may end browsing or select to continue accessing. Continue to access, the user equipment is connected to the initial data In the request, the webpage that you want to visit, such as Sina, Baidu, etc., the flow can refer to the embodiment shown in FIG. 1, so no further details are provided.
