The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments.

As shown in FIG. 1 , the architecture of the data service processing method applied by the embodiment of the present invention may include a data gateway, a mobility management network element, and a policy control network element.

The data gateway may include one of a Packet Data Network Gateway (PGW), a Gateway GPRS Suport Node (GGSN), and a Unified Packet Gateway (UGW), wherein the UGW includes a PGW. And Serving Gateway (SGW). The mobility management network element may include a Mobility Management Mnt (MME) or a Serving GPRS Support Node (SGSN). The policy control network element may include a Policy Charging and Rules Function (PCRF).

In an example, the foregoing architecture may further include a domain name server (DNS) and a roaming user home data gateway, where the home data gateway may be one of a PGW, a GGSN, and a UGW.

The data service method of the embodiment of the present invention may be used for a scenario in which a user of a non-contracted roaming data service and a user who subscribes to a roaming data service use a local data service.

In the embodiment of the present invention, the network may notify the roaming user to open the user equipment (User Equipment, UE) by using a Circuit Switching (CS) short message, if the roaming user turns off the data switch of the user equipment (User Equipment, UE). Data switch.

In the embodiment of the present invention, the Home Subscriber Server (HSS) of the roaming home or the home location register of the roaming location can receive the authentication request of the roaming user, and issue the authentication data to the legal roaming user, so that the authentication data is sent. Legitimate roaming users can attach to the network.

As shown in FIG. 2, an embodiment of the present invention provides a method for processing a data service, where the execution subject of the method is a data gateway, and the following steps are included.

Step 201: The data gateway receives a request for creating a data bearer session from the mobility management network element, where the request for creating a data bearer session is activated by the user equipment UE of the roaming user.

When a roaming user wants to access the network, the UE used by it activates the data bearer session. The mobility management network element searches for the corresponding data gateway for the user through the locally configured information, and sends a request for creating a data bearer session to the data gateway. The mobility management network element may be a mobility management network element visited by the roaming user; the data gateway may be a data gateway visited by the roaming user.

In an example, the mobility management network element, for example, the SGSN or the MME, may be configured locally, so that the mobility management network element can point the network access request of the roaming user to the data gateway where the mobility management network element is located, instead of pointing to roaming The data gateway where the user belongs. For example, the information can be configured in the mobility management network element of Shanghai: "3gnet.mnc002.mcc460.gprs" Shanghai Data Gateway IP", so that all users, including roaming users coming to Shanghai, can access the network access. Shanghai's data gateway.

Step 202: The data gateway sends a query request to the policy control network element, so that the policy control network element queries the subscription information of the roaming user, where the subscription information is valid local data service of the user. Subscribe to the information.

After receiving the request to create a data bearer session, the data gateway may send a query request to the policy control network element. After receiving the query request, the policy control network element can go to the user database to find the subscription information of the user.

The subscription information is the subscription information of the local data service that is valid for the user, and the local data service specifically refers to the local data service of the user's visited place. The subscription information of the valid local data service may mean that the user subscribes to the local data service, and the subscribed service does not exceed the subscription limit of the subscribed service during the validity period or the user's data usage condition, so that the user can continue to use the subscription. Business information.

Moreover, the policy control network element can also record the number of times the user attempts to access the Internet or access the Internet.

Step 203: The data gateway receives a result of the query from the policy control network element.

The policy control network element can feed different query results to the data gateway according to different conditions after the query.

In an example, if the policy control network element does not query the subscription information of the user, it indicates that the user does not subscribe to the local data service of the visited place, and the result of the query fed back to the data gateway may include a redirection rule.

In one example, if the policy control network element does not query the subscription information for the user and the user is attempting to access the Internet for the first time at the visited location, the result of the query may include a redirection rule.

In an example, if the policy control network element does not query the subscription information of the user, and the user does not attempt to access the Internet or access the Internet for the first time, and the user subscribes to the roaming agreement, the result of the query may include indication information, The indication information is used to instruct the data gateway to query the home data gateway of the user.

In an example, if the policy control network element queries the subscription information of the user, the user has subscribed to the local data service of the visited place, and the data service is valid. The result of the query fed back to the data gateway may include rule information for the subscription information.

Step 204: The data gateway processes the request for creating a data bearer session according to the result of the query.

The different information contained in the results of the data gateway query processes the request to create a data bearer session accordingly.

In one example, the results of the query can include a redirection rule. The data gateway may send a create data bearer session success message to the mobility management network element; receive the network access request of the user; redirect the network access request to the visited local data service service website according to the redirect rule, so that the user subscribes Local data services; thus enabling users to quickly and easily subscribe to local data services in the visited area.

In an example, on the basis of the above example, if the user subscribes to the local data service through the local data service service website, the local data service service website may notify the policy control network element of the subscription result of the user, and the policy control The network element can add the purchase information of the user to the user database. And, after the user subscribes to the local data service, the policy control network element may further send a data bearer session termination message to the data gateway; after receiving the data bearer session suspension message, the data gateway starts the data bearer session deletion process, thereby deleting the data bearer. Conversation.

In one example, the user is a user who has signed up for data roaming. When the user does not subscribe to the local data service of the visited place, the data gateway can route its network access request to its home data gateway when the first data is not built. At this point, the data gateway acts as a gateway proxy for the home data gateway. Specifically, the result of the query sent by the policy control network element to the data gateway may include indication information, where the indication information is used to instruct the data gateway to query the home data gateway of the user. After receiving the indication information, the data gateway may query the DNS for the user's home data gateway, and the DNS may send the IP address of the user's home address to the data gateway; the data gateway may serve as a gateway proxy to send a request for creating a data bearer session to the home. Ground data gateway.

In one example, the results of the query may include rule information for the subscription information. The data gateway information sends a create data bearer session success message to the mobility management network element to enable the user to use the subscribed local data service for network access. When the user performs network access, the data gateway monitors the usage of the local data service according to the rule information, and sends the usage to the policy control network element.

With the method provided by the embodiment of the present invention, the roaming user can subscribe and use the local data service of the visited place through the data gateway of the visited place without using the visited SIM card, thereby saving the cost of the user using the data service, and facilitating The user's operation improves the user experience.
