Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a subscription service processing method, a gateway, and a system. Background technique

Mobile users accessing the service server may require intermediate network element processing, such as network accelerators, firewalls, or virus filters. The services provided by such intermediate network elements often require users to sign up, so that the user's service traffic is controlled to reach the service server according to the contract. The intermediate network element generally provides a small bandwidth. If all the packets are not selected and passed through the intermediate network element, the packets of all users cannot be carried.

In the prior art, the GGSN (Gateway GPRS Support Node) is used to selectively process the loopback. The packets of the subscribers are selectively passed through the intermediate NEs to selectively process the services. The multiple routing loopback methods of the GGSN are as follows: Different intermediate network elements are attached to the interface of the GGSN. After receiving the packet, the GGSN determines that the packet belongs to the packet of the subscriber, and forwards the packet to an intermediate network element corresponding to the service contracted by the subscriber. The intermediate network element returns the packet after processing the packet. GGSN, the GGSN forwards the packet to the next intermediate network element according to the forwarding policy, and the next intermediate network element processes the message and then returns the message to the GGSN, and so on, and the packet passes through all the intermediates corresponding to the subscription service. After processing by the network element, it is forwarded by the GGSN to the service server.

However, if there are too many intermediate NEs and multiple loopbacks of the user's packets, the GGSN will process the same packet multiple times, which will have a greater impact on the performance of the GGSN. Summary of the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a method for processing a subscription service according to an embodiment of the present invention. In the embodiment of the present invention, the gateway may be a GGSN or a PGW (Packet Gate Way). As shown in FIG. 1, this embodiment includes:

Step 11: The gateway receives the message.

The packet may be an uplink packet sent by the user equipment to the service server, or may be a downlink packet sent by the service server to the user equipment.

Step 12: The gateway determines the forwarding path information of the packet according to the subscription information of the user when the user to which the packet belongs is the subscription information, and the forwarding path information includes path information of all the intermediate network elements that the packet will arrive in sequence. A user who has signed up for a network acceleration service, a firewall service, or a virus filtering service. A user can sign up for a business or sign up for multiple services.

The gateway determines whether the user to which the packet belongs is subscribed to the user according to the user address in the packet. For example, when the packet is an uplink packet, the gateway searches for the user subscription information of the user to which the packet belongs according to the source address of the packet, and determines that the user to which the packet belongs is the subscription user. When the destination address of the packet is queried, the user to which the packet belongs is identified as the subscriber. For a packet belonging to a subscriber, the gateway can determine all intermediate network elements that the packet needs to pass according to all the subscribed services of the user. For a packet that does not belong to the subscriber, the gateway does not need to go through the intermediate NE processing. The gateway does not need to forward the packet to the intermediate NE. Directly forwarded to the subsequent network element. For example, for the uplink packet, the gateway forwards the uplink packet to the router connected to the service server; for the downlink packet. The gateway forwards the downlink packet to the user equipment. The intermediate network element is a device that performs service processing and service forwarding. The difference between the service server and the intermediate network element is that the service server only processes the packets and does not forward the packets. The intermediate network element also needs to forward the packets to other network elements.

When the gateway determines that the user to which the packet belongs is the subscription user, the gateway obtains the forwarding path information including the path information of all the intermediate network elements that the packet will arrive in sequence according to the subscription information of the user. Specifically, when the gateway determines that the user to which the message belongs is a subscription user, the gateway determines the subscription service of the user according to the user address in the message. When the user subscribes to multiple services, the user has multiple service forwarding policies, and the gateway needs to obtain the service forwarding policy of all the subscribed services of the user, so as to obtain the address of the intermediate network element corresponding to all the subscribed services of the user. information. Each service forwarding policy includes a subscription service and address information of each intermediate network element corresponding to the subscription service. The gateway generates forwarding path information including all the intermediate network element address information, and adds the forwarding path information to the first hop intermediate network indicated by the forwarding path information, according to the address information of each intermediate network element corresponding to the service of all the subscribed services of the user. yuan. As the packet includes the address of the intermediate network element, the upstream intermediate network element can obtain the address of the next-hop intermediate network element when forwarding the packet, and forward the packet to the intermediate network element.

The gateway can save user subscription information and service forwarding policies. The user subscription information and service forwarding policy saved by the gateway may be obtained by the gateway from its own configuration, or may be obtained by the gateway from an external network element (for example, a PCRF). In addition, the gateway may not save user subscription information and service forwarding policies. After the packet is received, the user subscription information stored in the external network element is used to determine whether the user to which the current packet belongs is a subscription user, and the service forwarding policy of the user is obtained from an external network element (for example, a PCRF). The address of each intermediate network element corresponding to all the subscription services of the user is obtained.

Step 13: The gateway sends the packet containing the forwarding path information to the intermediate network element according to the forwarding path information, so that the intermediate network element processes the packet.

The gateway sends the first hop intermediate network element indicated by the forwarding path information according to the forwarding path information. Send a packet containing the forwarding path information. After processing the packet of the gateway, the first-hop intermediate network element deletes its own address in the path information, and forwards the modified packet to the intermediate network element in the next hop according to the indication of the forwarding path information. The intermediate network element processes the received packet in turn, and each intermediate network element deletes its own address in the forwarding path information after processing the packet, and forwards the modified packet to the next hop intermediate network in the forwarding path information. The element receives the message until the last hop intermediate network element in the forwarding path information.

When the packet is an upstream packet from the user equipment, the last hop intermediate network element continues to forward the packet to the service server after receiving the uplink packet of the service. Therefore, for the same upstream packet of the subscriber, the gateway only needs to process it once.

If the packet is a downlink packet from the service server, the user subscription information is obtained by the gateway, and the gateway is a necessary network element for the downlink packet to the user equipment. The downlink packet processed by the intermediate network element must pass the downlink packet. The gateway forwards to the user device. Therefore, the address of the last hop device in the forwarding path information needs to be set to the address of the gateway. After receiving the downlink packet, the last intermediate network element forwards the packet to the gateway according to the indication of the forwarding path information, and the gateway sends the packet to the user equipment of the subscriber. Therefore, for the same downlink message of the subscriber, the gateway only needs to process twice.

In the embodiment of the present invention, after receiving the packet, the gateway obtains the forwarding path information of each intermediate network element corresponding to all the subscription services of the user, and sends the forwarding path information in the packet. The first hop intermediate network element indicated by the forwarding path information. The packet includes the forwarding path information of the intermediate network element corresponding to all the subscription services of the user, and the packet can flow through all the intermediate network elements corresponding to all the subscription services of the user. When the packet received by the gateway is an uplink packet, the last hop intermediate network element receives the packet, and then sends the packet to the service server that provides the service service or the router that is connected to the service server. Therefore, for the uplink message of the subscriber, the gateway only needs to process once. When the packet received by the gateway is a downlink packet, the last hop intermediate network element receives the packet, and then forwards the packet to the gateway according to the indication of the forwarding path information, and the gateway sends the packet to the subscriber. User equipment. Therefore, for the downlink message of the subscriber, the gateway only needs to process twice. Therefore, the gateway does not need to be the same for the signing user. A message is processed multiple times to improve the performance of the gateway. In addition, since the gateway forwards only the packets belonging to the subscribers to the intermediate network element, the packets of all users can be prevented from passing through the intermediate network elements, which reduces the load on the intermediate network elements.

FIG. 2 is a flowchart of a method for a gateway to obtain a service forwarding policy according to an embodiment of the present invention. As shown in Figure 2, before step 11, it also includes:

Step 21: The gateway receives an activation request sent by the user equipment, including the user identifier.

Step 22: The gateway sends a policy request request including a user identifier to a Policy Charging Rules Function (PCRF).

Step 23: The gateway receives the user subscription information and the service forwarding policy corresponding to the user identifier sent by the PCRF.

After receiving the policy request request sent by the gateway, the PCRF obtains the user subscription information corresponding to the user identifier according to the user identifier, and determines the address of all the intermediate network elements corresponding to the subscription service, and the corresponding information includes the subscription service and the subscription service. The service forwarding policy of the correspondence between the address information of the intermediate network elements. The gateway receives the user subscription information and the service forwarding policy delivered by the PCRF through the Gx interface.

In addition, the above-mentioned user subscription information and service forwarding policy may also be built in the gateway local. If the service forwarding policy is built in the gateway, the gateway does not need to receive the service activation request sent by the user equipment, and does not need to send a policy request request to the PCRF.

The gateway can save the user subscription information in the user subscription information table as shown in Table 1. The service forwarding policy can be saved in the service forwarding table as shown in Table 2. As shown in Table 1, a user can have one or more contracted services. As shown in Table 2, a subscription service may correspond to an intermediate network element address or multiple intermediate network element addresses.

Table 1 is the user signing information form.

User address signing service

User Address 1 Contract Business ^ Contract Business C

User address 2 Signing business 8. Signing business ^ Signing business C

User Address 3 Contract Business A Table 2 shows the service forwarding table.

The gateway can query the user subscription information table according to the user address in the packet to determine whether the user to which the packet belongs is a subscription user. When the gateway determines that the user to which the packet belongs is the subscription user, the gateway obtains the address information of all the intermediate network elements corresponding to all the subscription services of the user in the service forwarding table according to all the subscription services of the user.

FIG. 3A is a flowchart of still another method for processing a contract service according to an embodiment of the present invention, and FIG. 3B is a diagram of an application scenario of another method for processing a contract service according to an embodiment of the present invention. As shown in Figure 3B, the GGSN includes three interfaces: a Gn interface connected to the SGSN (Service GPRS Support Node), a Gx interface connected to the PCRF, and a Gi interface connected to the router or other intermediate network element. The intermediate network elements corresponding to the user's subscription service are Processl, Process3, and Process5. The difference between the intermediate network element and the service server is as follows: After the intermediate network element processes the message, it continues to forward the message to other network elements, and the service server is the server that provides the service, and does not forward the message. As shown in FIG. 3A, this embodiment includes:

Step 1: The GGSN receives the uplink packet from the Gn interface to the service server, and the uplink packet includes the user identifier.

Step 2: The GGSN processes the uplink packet, and determines whether the user to which the uplink packet belongs is a subscription user.

The gateway can query the user subscription information according to the user address in the uplink packet, and when the user subscription information corresponding to the user address is queried, determine that the user to which the uplink packet belongs is a subscription user;

The GGSN determines that the user to which the uplink packet belongs is not a subscription user, and the GGSN directly forwards the GGSN to the router directly connected to the corresponding service server through the Gi interface. Step 3: When the GGSN determines that the user to which the uplink packet belongs is the subscription user, the GGSN obtains the IP address of the intermediate network element corresponding to all the subscribed services of the user according to the services of all the subscribed services of the user, and generates the intermediate network element Processl in sequence. The forwarding path information of Process3 and Process5 is added to the uplink packet.

The intermediate network element corresponding to all the subscription services of the user to which the uplink belongs is Processl.

Process3 and Process5. The forwarding path information generated by the GGSN is path information that sequentially reaches the intermediate network elements Processl, Process3, and Process5. The GGSN adds the forwarding path information to the routing options of the IP packet header.

Step 4: The GGSN sends the uplink packet including the forwarding path information to the Gi interface. Step 5: The GGSN sends the uplink packet including the foregoing forwarding path information to the Process1 through the Gi interface.

Step 6: After processing the uplink packet, Processl forwards the uplink packet to the intermediate network element Process3 according to the indication of the forwarding path information.

After processing the uplink packet, Processl deletes its own address in the forwarding path information and sends the uplink packet to the next intermediate network element Process3.

Step 7: After processing the uplink packet, Process3 forwards the uplink packet to the intermediate network element Process5 according to the indication of the forwarding path information.

After processing the uplink packet, Process3 deletes its own address in the forwarding path information and sends the uplink packet to the next intermediate network element Process5.

Step 8: After processing the uplink packet, Process 5 forwards the uplink packet to the router connected to the service server.

After processing the uplink packet, Process5 deletes its own address in the forwarding path information and sends the uplink packet to the router connected to the service server.

In this embodiment, when the GGSN determines that the user to which the received uplink packet belongs is not the subscription user, the GGSN directly forwards the uplink packet to the router directly connected to the service server through the Gi interface. When it is determined that the user to which the received uplink packet belongs is a subscription user, the GGSN adds a forwarding path to the uplink packet. The information is sent to the first hop intermediate network element.

This embodiment mainly describes the downlink traffic processing method of the contracted service. As shown in FIG. 4A, this embodiment includes:

Step 1: The GGSN receives the downlink packet including the user identifier from the Gi interface.

Step 2: The GGSN determines whether the user to which the downlink message belongs is a subscription user.

When the GGSN determines that the user to which the downlink packet belongs is not the subscription user, the GGSN directly performs step 9: internal processing the downlink packet, and then forwards the downlink packet to the user equipment through the Gn interface.

Step 3: When the GGSN determines that the user to which the downlink message belongs is a subscription user, the GGSN obtains the IP address of the intermediate network element corresponding to all the subscribed services of the user according to the services of all the subscriptions of the user, and generates the intermediate network element sequentially. The forwarding path information of Process5, Process3, Processl, and GGSN is added to the downlink packet.

The intermediate network elements corresponding to all the contracted services of the user to which the downlink belongs are Processl, Process3, and Process5. The GGSN generates forwarding path information that sequentially reaches the intermediate network elements Process5, Process3, and Processl, and the GGSN. The address of the last hop device in the above forwarding path information is the IP address of the GGSN.

Step 4: The GGSN sends the downlink packet including the forwarding path information to the Gi interface. Step 5: The GGSN sends the downlink packet including the foregoing forwarding path information to the Process 5 through the Gi interface.

Step 6: After processing the uplink packet, Process5 forwards the downlink message to the next hop intermediate cell Process3 according to the indication of the forwarding path information.

After processing the downlink packet, Process5 deletes its own address in the forwarding path information and sends the downlink packet to the next intermediate network element Process3.

Step 7: After processing the uplink packet, Process3 forwards the downlink message to the next hop intermediate cell Process 1 according to the indication of the forwarding path information.

After processing the downlink packet, Process3 deletes its own address in the forwarding path information. The text is sent to the next intermediate network element Process 1.

Step 8: After processing the uplink packet, Process 1 forwards the downlink packet to the GGSN according to the indication of the forwarding path information.

After processing the downlink packet, Process 1 deletes its own address in the forwarding path information and sends the downlink packet to the next intermediate network element GGSN.

Step 9: The GGSN performs internal processing on the downlink packet.

Step 10: The GGSN sends the downlink packet to the Gn interface.

Step 11: The GGSN forwards the downlink packet to the SGGN through the Gn interface.

In this embodiment, when the GGSN determines that the user to which the received downlink message belongs is not the subscription user, the GGSN forwards the uplink packet to the user equipment through the Gi interface. When it is determined that the user to which the received downlink message belongs is a subscription user, the GGSN adds the forwarding path information to the downlink packet and sends the information to the first hop intermediate network element. Upon receiving the downlink packet sent by the last intermediate network element, the GGSN forwards the packet to the SGGN through the Gn interface.
