As shown in FIG. 2, the corresponding first network and the second network of the multi-mode multi-access terminal use the same PGW and perform information interaction with the same server. It should be noted here that the first network and the second network only represent at least two networks corresponding to the multi-mode multi-access terminal, and are not limited to two networks.

The following is a detailed description of how different systems can use the same PGW for different networks.

Method embodiment 1

The embodiment of the present invention provides a service processing method for a multi-mode multi-access terminal. As shown in FIG. 3, the method includes the following steps: Step 101: A first network supported by a multi-mode multi-access terminal performs normal network attachment, and is established on a gateway entity. connection. The gateway entity may be an SGW or a PGW. The following uses an example of a PGW as a gateway entity.

Step 102: The second gateway unit of the second network supported by the multi-mode multiple access terminal acquires an address of a gateway entity used by the first network, that is, an address of the PGW.

Specifically, if the second network is a non-3GPP network, the second gateway unit may obtain the address of the PGW from the authentication server in the process of performing the second network authentication with the authentication server; or, if The second network is a 3GPP network, and the second gateway unit may acquire an address of the PGW in a process of inserting a subscription data.

Specifically, the authentication server may be a Home Subscriber Server (HSS)/Authentication, Authorization and Accounting (AAA) server.

Step 103: The multimode multiple access terminal or the first of the first network that has completed registration The gateway unit sends an attach request message to the second gateway unit of the second network, where the attach request message carries multiple access start indication information.

Specifically, when the first network is a 3GPP network and the second network is a non-3GPP network, the first gateway unit may be a Mob i le Management Entity (MME), and the second gateway unit. When the first network is a non-3GPP network and the second network is a 3GPP network, the first gateway unit may be a non-3GPP access gateway, and the second gateway unit may be an MME. The attach request message may also be sent by the multi-mode multi-access terminal, whether the multi-mode multi-access terminal is sent by the multi-mode multi-access terminal or the first gateway unit is determined by the networking structure of the communication system, and does not affect the beneficialness of the embodiment of the present invention. effect. If the communication interface between the first gateway unit and the second gateway unit is available for information interworking, the sending of the attach request message by the first gateway unit may be beneficial to reduce the workload of the multi-mode multi-access terminal.

It should be noted here that there is no necessary sequence relationship between this step and step 102, that is, the process of sending an attach request message first, and then performing the second network authentication is also possible. Moreover, the multiple access initiation indication information sent by the multimode multiple access terminal may also be sent in the authentication process in step 102.

Step 1104: After receiving the attach request message, the second gateway unit of the second network sends a connection establishment request to the corresponding PGW according to the address of the PGW. After receiving the PGW, the user is established on the PGW. Related information, such as user identification, data transmission path information, and the like; and transmitting the multiple access initiation indication information to the PCRF entity by using the PGW.

Specifically, when the second network is a 3GPP network, the establishing a connection request message may be a setup bearer request; when the second network is a non-3GPP network, the establishing a connection request may be a binding update request. Step 105: After receiving the multiple access initiation indication information, the PCRF entity sends a PCC rule with a corresponding network type parameter to the first network and the second network of the used PGW.

Specifically, different network type parameters may be set for the first network and the second network, for example, a Radio Access Technology (RAT) type parameter, and the corresponding PCC rule is bound. And sent to the PGW in one outgoing message or two independent outgoing messages. Since the PCC rule is a combination of a series of parameters, it is also possible to add a RAT type parameter to the PCC rule for distinguishing different PCC rules.

It should be noted that the PCRF entity sends a PCC rule to the PGW and not to the PGW, but in general, the gateway entity The PGW can contain PCEF entities, so it can also be regarded as issuing PCC rules to the PGW.

Step 106: The PGW saves the received PCC rule. After the PGW receives the service data, the PGW matches the saved data with the saved PCC rule, and according to the network type parameter in the matched PCC rule. The service data is sent to a corresponding network.

The business data is the content that the user needs to obtain.

In the following, the specific signaling procedure of this embodiment is described by taking the 3GPP network as the first network and the non-3GPP network as the second network, that is, the 3GPP network is registered first, and then the registration of the non-3GPP network is taken as an example. As shown in FIG. 4A, the following process is included:

1-1. The 3GPP network performs a standard registration process, selecting and using a PGW;

1-2. The multi-mode multi-access terminal performs a non-3GPP authentication process to the AAA/HSS server, and the AAA/HSS server returns the address of the PGW used by the 3GPP network to the non-3GPP access gateway;

Wherein, when performing a non-3GPP authentication procedure, the multimode multiple access terminal may also be to the non-3GPP network. The access gateway sends the multiple access initiation indication information, so that the non-3GPP access gateway learns that the multimode multiple access terminal is in a multiple access state;

1-3. The multi-mode multiple access terminal sends an attach request message to the non-3GPP access gateway.

In addition, if the multimode multiple access terminal does not send the multiple access initiation indication information to the non-3GPP network access gateway in the foregoing step 1-2, the multimode multiple access terminal may perform the attach request in this step. The message carries multiple access initiation indication information to the non-3GPP access gateway.

1-4. After receiving the attach request message, the non-3GPP access gateway sends a Proxy Binding Up Update (PBU) message to the corresponding PGW according to the received address of the PGW. The multi-access open indication information is carried.

1-5. The PGW sends a session establishment indication to the PCRF entity. The multi-access initiation indication information is also carried by the PW.

After receiving the bearer session establishment indication message, the PCRF entity learns that the multi-mode multi-access terminal is currently in a multi-access open state and performs subsequent Non-3GPP network registration process.

As shown in FIG. 4B, the following process is included:

2- 1. The non-3GPP network performs the normal registration process, selecting and using a PGW;

2-2. The multimode multiple access terminal sends an attach request message to the solid E. The device carries multiple access opening indication information.

2-3. The multi-mode multi-access terminal and the AAA/HSS server perform an authentication process of the non-3GPP network; 2-4. The AAA/HSS server performs a process of inserting a subscription data with the MME, The address of the PGW used by the 3GPP network is sent to the MME;

Since the 3GPP technology is different from the non-3GPP technology, the steps of obtaining the PGW address are also different; in the 3GPP technology, the process of inserting the subscription data is usually completed, and since the non-3GPP does not insert the subscription data flow, it can only be in the authentication process. Pass the address of the PGW.

2-5. The MME sends a default bearer request to the SGW, where the multiple access initiation indication information and the address of the PGW are carried.

2-6. The SGW sends a default bearer request to the corresponding PGW according to the received address of the PGW, where the SGW carries the received multiple access start indication information.

2-7. The PGW and the PCRF entity perform an interaction to obtain a PCC rule, where the multi-access initiation indication information is carried, and is used to notify a status of a current multi-mode multi-access terminal of the PCRF entity, so as to facilitate subsequent delivery of the PCC rule. Use

The user subscription data is provided to the second gateway unit by the authentication server in advance. The second gateway unit can determine, according to the user subscription data, whether the operator allows the multi-mode multi-access terminal to use the multi-access function supported by the multi-mode multi-access terminal. Specifically, if the second gateway unit is MN, the authentication server may send the user subscription data to the MME in a process of inserting a subscription data; if the second gateway unit is a non-3GPP access gateway, The authentication server may send the user subscription data to the non-3GPP access gateway in an authentication process.

It should be noted that the first gateway unit and the second gateway unit are numbers for convenience of description, and do not indicate a sequence. In the actual system operation process, the gateway units serving different networks are independently operated, and the multi-mode multi-access terminal is known only when a gateway unit obtains the address of the PGW in step 202.
