Used for fixed networks and third-party network or application servers

Method and device for interaction

Technical field

The present invention relates to communication networks, and more particularly to a method and apparatus for interacting a fixed network with a third party network or application server. Background technique

In the current 3G wireless communication technology, macro cell-based communication may result in a decline in indoor service quality due to poor penetration characteristics of the building's radio frequency to the building. Therefore, research on fixed mobile convergence networks based on femtocells and other similar technologies has become a hot topic in the industry. In the logical structure of the fixed mobile convergence network shown in FIG. 1, a femtocell base station such as a home base station (BSR) is deployed indoors and is fixedly connected via an access node (AN). The access network is connected to the mobile core gateway such as the Brick of the mobile core network via the IP network through the Broadband Network Gateway (BNG), and the mobile core network gateway is followed by the CS (Circuit Switched) domain and the PS. A switching device of a (packet switched) domain, such as an MSC, is connected to an SGSN and a GGSN or the like (not shown). The BSR connects the communication of the voice and data services of the mobile device, such as the mobile phone MS or the Personal Digital Assistant (PDA), to the mobile interface based on the standard interface via the fixed access network through the fixed network gateway and the mobile network gateway. network. It can be seen that the fixed mobile convergence technology can be used as a solution for extending the indoor coverage of mobile communication, with the fixed access network as its return channel; and the access point such as BSR is plug and play, and can be connected to any existing based IP access network, effectively improve indoor coverage and service shield.

In order to ensure that the fixed mobile convergence technology can utilize the fixed access network resources, the wireless service communication of the mobile core network should be normally transmitted via the fixed access network, and the wireless service of the fixed access domain to the mobile user and/or the mobile device should be enabled. Monitor. For example, fixed access The network shall allocate mobile subscribers (and/or mobile devices) with fixed access network resources such as links and bandwidths carrying their wireless service data, and shall be able to monitor communication data of mobile users (and/or mobile devices) and the like. In particular, when providing a mobile device with a broadcast or multicast service with a large data traffic such as mobile TV, the fixed access network should establish a virtual local area network between its fixed access network gateway and the access node accessed by the mobile device. (VLAN) transmission channel, and set its delay, bandwidth, priority, and so on. Therefore, it is necessary for the fixed access network and the mobile core network to be set according to the service policy.

Since in the fixed mobile convergence network, the fixed access network and the mobile core network are in two different management domains, further, they are also assigned to different communication carriers. Therefore, at present, before the service is deployed, the communication carriers of the fixed access network and the mobile network configure the fixed access network and the mobile core network according to the pre-agreed service policy. The configuration is then fixed relatively, unless specifically reconfigured. Since the service policy is a fixed configuration, it is difficult for the mobile core network to coordinate with the fixed access network in real time and flexibly, and control the service at different granularities. For example, for broadcast and/or multicast services, the fixed access network operator configures VLANs for several multicast groups in advance between the fixed network gateway and certain fixed ANs accessed by some BSRs, and the AN opens the corresponding port. Through these ANs, the broadcast and/or multicast services corresponding to the multicast group are provided to the mobile devices MS under the jurisdiction of these BSRs. In this case, if the AN to which a BSR belongs to the mobile device does not have the corresponding port enabled, and the fixed access network does not have a VLAN configured, the fixed access network cannot provide bearer broadcasts to the mobile device. Communication resources of the multicast service. In all scenarios where fixed access network and mobile network interaction are required (such as fixed network interception and monitoring of communication of mobile devices via its network), similar problems exist in the prior art.

In addition, with the development of communication services, more and more communication services need to be sent to users through fixed access networks. The configuration of the existing fixed access network is a fixed configuration, and the real-time variable configuration cannot be implemented according to the request of the third-party network or the application server, thereby causing the network resource utilization efficiency to be low. Summary of the invention In order to solve the above problem, it is very necessary for the fixed mobile convergence network to allow the fixed access network and the mobile core network to flexibly perform service policy control. Further, for services such as broadcast and/or multicast, it is necessary for the fixed access network to configure a fixed access network VLAN, bandwidth, delay, etc. service policy for its mobile device in real time. In addition, it is also important that the fixed access network can implement real-time variable configuration according to the request of the third-party network or the application server.

According to a first aspect of the present invention, a method for performing cross-domain policy control between a fixed access network and a mobile core network in a fixed mobile convergence network is provided, wherein the method includes the following steps: a. and the mobile core network Inter-domain policy control information is exchanged, and corresponding policy control processing is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to Figure 2, an embodiment of one aspect of the present invention will be described in detail from a method perspective.

According to an embodiment of the present invention, the fixed access network and the mobile core network interact with each other across the domain policy. Slightly control the information and perform corresponding policy control processing. In this embodiment, the mobile core network sends a service policy configuration request to the fixed access network, and requests a corresponding policy for its service as an example for description. It can be understood that the present invention is not limited thereto; according to the present invention, any other cross-domain control information may be exchanged between the two, for example, user authentication and charging information sent by the fixed access network to the mobile core network.

Further, the service policy configuration request configures a request for a broadcast and/or multicast service policy, and the fixed access network configures a VLAN and a bandwidth thereof for a multicast service such as broadcast and/or multicast provided by the mobile core network to the mobile device, Delay and other service strategies. It can be understood that the present invention is not limited thereto, and the service policy configuration request may also be a monitoring request of the mobile core network to a mobile terminal, so as to locally bypass and legally intercept the communication of the mobile terminal in the fixed access domain. This operation will be described later in this specification with filtering and the like.

As shown in Figure 2, first, the mobile terminal MS has subscribed to one or more broadcast and/or multicast services, which are represented by the corresponding one or more multicast addresses. The mobile terminal MS accesses a BSR, and the AN to which the BSR belongs has not configured a VLAN for the multicast address. In this case, the mobile core network first verifies the identity of the mobile terminal or its user and whether it subscribes to the broadcast and/or multicast service through the BSR and the IPSec tunnel established by the mobile core network, and the verification can be performed through the HLR ( Home location register), AAA (authentication, authorization and accounting) server, etc. The specific verification manner is well known to those skilled in the art, and the present invention will not be described herein.

After the verification is passed, in step S10, the mobile core network generates a broadcast and/or multicast service policy configuration request, where the request may include an identifier of the mobile operator to which the mobile device MS belongs, and request the fixed access network to access the mobile network. The number of multicast groups, the corresponding multicast address of the multicast group, and the bandwidth and other parameters.

Preferably, since the mobile core network and the fixed access network are two different management domains, the confidentiality of inter-domain communication is very important. Therefore, embodiments of the present invention propose that the mobile core network transmits a broadcast and/or multicast service policy configuration request to the fixed access network based on the AAA protocol.

Specifically, this embodiment takes the Diameter protocol, which is currently widely used, as an example. It will be understood by one of ordinary skill in the art that the present invention is not limited to the Diameter protocol. In the Diameter NAS application, the peer-to-peer Diameter nodes exchange the identity of the node and its capability information through a Capacities Exchange message. The initiator can use the Capacities Exchange Request (CER). ), the other party uses Capacities Exchange Answer (CEA). The initiator sets the instruction code to 257, and the instruction flag "R" is set to 1 to identify the CER. The CER contains attribute value pairs (Attribute-Value-Pair, referred to as

AVP), to carry various interactive information of the CER, for example, as defined by the following data structure:

{ Origin-Host }

{ Origin-Realm }

1* { Host-IP-Address }

{ Vendor-Id }

{ Product-Name }

[ Origin-State-Id ]

* [ Supported- Vendor-Id ]

* [ Auth- Application-Id ]

* [ Inband-Security-Id ]

* [ Acct- Application-Id ]

* [ Vendor-Specific- Application-Id ]

[ Firmware-Revision ]

* [ AVP] where AVP with "[]" is optional AVP; AVP with " {} " is mandatory AVP. The parameters carried by each AVP and their respective data structures are well known to those skilled in the art, and the present invention will not be described herein. In addition, the Diameter protocol allows new AVPs to be defined and added to CER messages to meet actual needs.

In this embodiment, a broadcast and/or multicast service policy configuration request is put into a CER message by adding a new AVP to the CER message. For example, in one embodiment of the present invention, a group type AVP (Grouped AVP, which can logically accommodate multiple AVP AVPs) named Multicast-Addresses is newly created in the CER, and the extended CER is as shown in the following data structure: <CER>:: = < Diameter Header: 257, REQ >

{ Origin-Host }

{ Origin-Realm }

1* { Host-IP-Address }

{ Vendor-Id }

{ Product-Name }

{ Multicast- Addresses }

[ Origin-State-Id ]

* [ Supported- Vendor-Id ]

* [ Auth- Application-Id ]

* [ Inband-Security-Id ]

* [ Acct- Application-Id ]

* [ Vendor-Specific- Application-Id ]

[ Firmware-Revision ]

* [ AVP] The Multicast-Addresses group AVP structure is shown in the following data structure:

<Multicast-Addresses> ::= < AVP Header: xxxx >

{ Operator-Id }

{Multicast-Group-Number}

{ Multicast-Address }

{ Multicast-Bandwidth }

* [AVP] where the AVP code for this group of AVPs is specified by IANA (Internet Address Assignment Authority). Since it has not been specified yet, this manual is indicated by xxxx.

This group of AVPs includes four new AVPs:

The Operator-Id is used for the operator identifier, and is used to identify the mobile operator to which the mobile terminal MS belongs and request the multicast VLAN corresponding to the multicast address;

Multicast-Group-Number is the maximum number of multicast groups allowed by the mobile core network corresponding to the carrier. The data type can be 32-bit integer.

Multicast-Address is a multicast address, and its data type can be 64-bit integer;

Multicast-Bandwidth is the (maximum) multicast bandwidth corresponding to the multicast address, The data type can be a 32-bit integer.

In addition, new AVPs can be added according to other parameters and information of the actual system, and added to the Multi-Address-Addresses group AVP. The frame structure of this group of AVPs is shown in Figure 3. Wherein, if the "V" position is 1, the manufacturer identification field shall include the "SMI Network Management Private Enterprise Codes" specified by the IANA.

In summary, in step S10, the mobile core network generates a broadcast and/or multicast service policy configuration request based on the Diameter protocol.

Then, in step S12, the mobile core network sends the generated broadcast and/or multicast service policy configuration request to the fixed access network.

Preferably, as shown in FIG. 1, an embodiment of the present invention proposes to employ a network mobility policy controller to be responsible for generating and transmitting a broadcast and/or multicast service policy configuration request.

Next, in step S20, the fixed access network receives the broadcast and/or multicast service policy configuration request sent by the mobile core network.

Preferably, as shown in FIG. 1, an embodiment of the present invention proposes to receive a broadcast and/or multicast service policy configuration request by using a fixed network policy controller. Then, in step S12, the mobile network policy controller sends a broadcast and/or multicast service policy configuration request to the fixed network policy controller.

Since the present embodiment mainly relates to the application of the present invention in the configuration of a broadcast and/or multicast service policy, the service policy control is performed for the broadcast and/or multicast service in the fixed access network, for example, the main functional entity of the VLAN is configured. To fix the gateway BNG of the access network, preferably, the fixed network policy controller can be subordinate to the gateway BNG; further, it can also be physically integrated into the gateway BNG. It can be understood that the deployment mode is not unique. A person skilled in the art can deploy the policy controller in a suitable logical and physical form according to the actual interaction policy control information and the functional entity that performs policy control processing.

Then, in step S22, the fixed access network configures the service policy of the fixed access network according to the broadcast and/or multicast service policy configuration request.

Specifically, the fixed network policy controller will receive the broadcast and/or multicast service policy The request is provided to the gateway BNG; and the gateway BNG learns the BSR and the AN currently accessed by the mobile terminal MS through the DHCP server in the fixed access network, and the gateway BNG is the corresponding multicast address, using the ANCP (access node control) The protocol configures one or more VLANs of the corresponding bandwidth from the gateway BNG to the AN. Preferably, before configuring the VLAN, the gateway BNG also verifies the mobile terminal MS, the mobile operator, and the corresponding multicast address, bandwidth rights, etc. to determine whether to configure the request configuration for the broadcast and/or multicast service policy. The corresponding strategy. For example, the fixed access network may presuppose a list of multicast addresses that the fixed access network can bear with the mobile core network according to a rate agreement, etc.; when verifying the request, the gateway BNG determines whether the requested multicast address is an appointment. of. In another case, the gateway BNG can unconditionally configure a VLAN for the requested multicast address.

And, in step S24, the fixed access network sends a response to the broadcast and/or multicast service policy configuration request back to the mobile network policy controller through the fixed network policy controller. Preferably, the response of the broadcast and/or multicast service policy configuration request is also based on the Diameter protocol, using a CEA message. Unlike the CER message, the "R" bit of the CEA message is set to 0. In step S14, the network migration policy controller receives the response and notifies the corresponding policy enforcement point.

Since the gateway Brick is a functional entity that the mobile core network sends broadcast and/or multicast services to the fixed access network, preferably, the mobile network policy controller can logically be subordinate to the gateway Brick of the mobile core network; further, its physical It can also be integrated into the gateway Brick. It can be understood that the deployment mode is not unique. A person skilled in the art can deploy the policy controller in a suitable logical and physical form according to the actual interaction policy control information and the functional entity that performs policy control processing.

So far, resource reservations such as VLANs corresponding to one or more broadcast and/or multicast services subscribed by the mobile terminal have been completed. Since the user of the mobile terminal has not requested these services, these resources are reserved for backup so that data can be transmitted as soon as the user requests it.

Thereafter, when the user of the mobile terminal MS requests to play the multicast service, for example, when requesting to join the multicast group of the corresponding multicast address by using the IGMP protocol, the gateway Brick of the mobile core network broadcasts according to the mobile network controller. And/or multicast service policy configuration letter The data of the broadcast and/or multicast service with the corresponding multicast address is sent to the gateway BNG of the fixed access network. The gateway BNG sends the data of the multicast service to the AN in the corresponding VLAN, and provides the data to the mobile terminal MS through the BSR. The multicast communication process in a specific fixed mobile convergence network is well known to those skilled in the art, and the present invention will not be described herein.

By interacting with the cross-domain policy control information via the policy controller, the fixed access network and the mobile core network hide their respective network topology and access modes, thereby improving the security of cross-domain policy control.

It will be appreciated that the present invention is also applicable to a fixed access network configured for broadcast and/or multicast, bandwidth between an access node and a home micro base station, or configured for broadcast and/or multicast, a home micro base station Bandwidth between mobile devices and mobile devices.

In another embodiment of the invention, the fixed access network can be used to monitor wireless services for mobile users and/or mobile devices. Specifically, in a preferred embodiment, when the mobile terminal accesses the fixed access network through the BSR, the mobile core network may use the mobile network policy controller to request the fixed access network to monitor the monitoring configuration of the mobile device. The request is sent to the fixed network policy controller of the fixed access network; the fixed network policy controller may send the request to the BSR or AN accessed by the mobile terminal, and the BSR or AN may move the mobile device according to the monitoring request. The communication of the terminal performs local bypass, legal interception and filtering, and the like.

It can be understood that, in the foregoing embodiment, when the mobile terminal MS accesses the fixed access network through a certain BSR and the AN, the mobile core network and the fixed access network exchange broadcast and/or multicast service policy configuration request, and the corresponding correspondence is established for the AN. The VLAN of the multicast address. The invention is equally applicable to policy configuration in other situations, for example, the mobile terminal MS switches from one AN access path to another AN access path (eg, to the coverage of another BSR under another AN) The mobile core network interacts with the fixed access network to broadcast and/or multicast service policy configuration requests, and establishes a VLAN corresponding to the multicast address for the other AN. According to still another embodiment of the present invention, in a fixed network, a fixed access network interacts with a third-party network or an application server to control policy information, and performs corresponding policy control Reason.

A third-party network is all types of networks other than a fixed network, such as mobile networks and non-mobile networks. The mobile network can be a cellular network, a self-organizing network, and a mobile digital television network. Non-mobile networks can be sensor networks as well as television networks and the like. The application server includes an application server in a fixed network or a third-party application server that is not in a fixed network, such as an Internet Protocol Television (IPTV) application server and a Voice Over Internet Protocol (VOIP) application server. The present invention is not limited to cross-domain network transmission policy control, and the present invention can also be used to implement transmission policy control for services within a fixed network, for example, transmission policy control for Digital Subscriber Line (DSL).

The fixed access network interacts with the third-party network or the application server to control policy information including the fixed access network receiving policy control information from the third-party network or the application server or the fixed access network transmitting the policy control information to the third-party network or the application server. The policy control information can be various control information such as network resource configuration requests, user authentication and accounting information, and monitoring requests. For example, the third party network is a cellular mobile network that can provide multicast services, and the configuration request may include the identifier of the mobile operator to which the mobile device belongs, the number of multicast groups that the fixed access network requests to access, and the number of multicast groups. The corresponding multicast address of the broadcast group and parameters such as bandwidth.

In an embodiment in which the fixed access network receives the third-party network or the application server policy control information, the fixed access network receives the policy control information sent by the third-party network or the application server, and configures the fixed access according to the policy control information. Network service strategy.

The fixed access network may receive policy control information sent by a third-party network or an application server in multiple manners, for example, receiving policy control information through a local policy decision point of the fixed access network. Then, the broadband network gateway of the fixed access network receives the policy control information sent from the local policy decision point as a policy enforcement point, and parses the policy control information into specific subscriber line configuration information and sends the information to the access node. After receiving the subscriber line configuration information, the access node completes the specific transmission policy control according to the content of the subscriber line configuration information, such as configuring the line for the user. The fixed access network resolves the policy control information to the subscriber line configuration information through the broadband network gateway, and can provide the phase according to the service type in real time. The control strategy, such as multicast access control, enables the utilization of network resources to be adjusted in real time, thereby improving the utilization of network resources.

The following takes the fixed access network to receive the mobile TV policy control information as an example, and specifically describes the transmission of the subscriber line configuration information between the broadband network gateway and the access node of the fixed access network.

First, the policy controller/policy decision point of the mobile core network sends policy control information to the local policy controller/policy decision point of the fixed access network. The policy control information includes the number of broadcast/multicast channels, broadcast/multicast addresses, and broadcast/multicast bandwidth.

Second, the gateway BNG of the fixed access network receives policy control information from the local policy controller/policy decision point of the fixed access network as a policy enforcement point.

Then, the gateway BNG of the fixed access network parses the content included in the policy control information into the subscriber line configuration information of the AN of the fixed network, and sends the AN to the fixed network AN through the ANCP, that is, the permitted broadcast included in the policy control information The number of multicast channels, the broadcast/multicast address, and the broadcast/multicast bandwidth are parsed accordingly and sent to the AN of the fixed network.

Finally, the AN of the fixed network receives the subscriber line configuration information, and configures the user's communication according to the specific content included therein.

The transmission of the subscriber line configuration information between the broadband network gateway of the fixed access network and the access node is implemented by an access node control protocol, and the access node control protocol may transmit a loop service attribute, where the loop service attribute includes a multicast rate attribute And multicast access channel attributes.

The loop service attribute describes the service attributes of the third-party network or application server corresponding to the fixed access network. Taking a home base station router as an example, a home base station router uses a fixed access network as a network loop, and a loop service attribute describes a service attribute corresponding to a home base station router in a fixed access network.

Through the loop service attribute and the attribute values included in the loop service attribute, such as the multicast rate and the multicast access channel, the attributes of the subscriber line can be expressed, and then the access node performs access control on a specific line. If an attribute value is not resolved by the access node, the attribute value is ignored. In addition, new attributes can be added according to other parameters and requirements of the system to meet the requirements of policy control, such as adding the maximum number of multicasts allowed to join at the same time.

The access node control protocol enables dynamic adjustment and allocation of network bandwidth. The following takes the ANCP protocol as an example to specify the setting of the loop service attribute included in the access node control protocol, and the setting of the multicast rate and multicast access channel included in the loop service attribute.

The ANCP protocol is a two-way, IP-based control protocol that can be used for many different types of network elements in a DSL access network, such as Ethernet. It supports the necessary information exchange between the access node and the broadband network gateway, allowing the access node to complete the configuration of the subscriber line.

The ANCP protocol is extended by the General Switch Management Protocol (GSMP). The GSMP protocol is a communication protocol between an IP switch controller and an ATM (Asynchronous Transfer Mode) switch inside the IP switch, and is used by the IP switch controller to control the operation of the ATM switch. As shown in Figure 5, the ANCP protocol modifies the Port Management message format in the GSMP protocol and adds line configuration extensions to the port management messages. As shown in Figure 6, the first two bytes of the extended field represent the number of attribute values (TLVs, Type, Length, Value) contained in the entire extended domain. The third and fourth bytes represent the entire extended domain. Length in bytes.

The extended domain contains one or more TLVs, which represent different DSL line attributes. As shown in Table 1, the existing ANCP protocol includes an Access-Loop-Circuit-ID. Access-aggregation-Circuit-ID and attribute values such as Service-Profile-Name, where the type code is a hexadecimal number. Table 1

TLVs type code data value

Access-Loop-Circuit-ID 0x01 circuit line identification

Access-Aggregation-Circuit-ID 0x03 port identifier Service-Profile-Name 0x05 The format of the service attribute attribute value TLV is shown in Figure 7. Its length is always an integer multiple of 32 bits. If it is not full, it is filled with 0. The content is divided into 3 parts, type (Type), length. (Length) and value (Value). Where the length portion represents the actual number of bytes of the TLV (excluding the padded portion). Through these TLV values, the attributes of the subscriber line can be expressed, and the access node can perform access control on a specific line. If a TLV is not resolved by the access node, the TLV is ignored. In the existing ANCP protocol, only the conventional configuration of the subscriber line can be implemented, and the broadcast and multicast services are not involved.

In order to support user-side broadcast/multicast service provisioning, complete its multicast access and bandwidth policy control, as shown in Table 2, a new TLV-Backhauling-Service-Profile is introduced into the ANCP protocol. Table 2

As shown in Table 3, the loop service attribute value includes two new sub-attribute values: Multicast-Rates and Multicast-Channel-Access. table 3

For scalability requirements, you can add more sub-attribute values to the loop service properties to support other service properties. These new attribute values describe the broadcast/multicast configuration information for the DSL lines connected to the home base station router. The multicast rate represents the multicast bandwidth allowed by the DSL line connected to the home base station router. The multicast access channel indicates The multicast address allowed to access. A user DSL line may allow access to multiple multicast channels, so its corresponding loop service attribute may contain multiple multicast access channel sub-TLV values. In addition, new sub-TLV values can be added according to other parameters and requirements of the system to meet the requirements of policy control. For example, the upper limit of the number of multicasts that can be joined at the same time can be added.

The following is an example of a policy in which a fixed network receives policy control information sent by a third-party application server that is not in a fixed network, and specifically describes an access node control protocol, such as an extended

The ANCP protocol, the process by which a broadband gateway sends line configuration attributes to an access node.

First, the third-party application server sends policy control information to the local policy decision point of the fixed access network.

Second, the local policy decision point of the fixed access network issues the policy control information to the gateway BNG of the corresponding fixed network for specific execution.

Then, the gateway BNG of the fixed network resolves the transmission control policy of the subscriber line in the policy control information to the corresponding TLV attribute value, and uses it as the subscriber line configuration information, and sends it to the AN of the fixed network through the extended ANCP protocol.

Finally, the AN of the fixed network receives the subscriber line configuration information and configures the user's communication according to the TLV attribute value included therein.

The above method parses the policy control information into subscriber line configuration information through an access node control protocol including a new attribute value, and sends it from the network broadband gateway of the fixed access network to the access point of the fixed access network. The method can also be applied to the method shown in Figure 2, so that the fixed network can configure the user's communication in real time according to the policy control information.

One embodiment of the present invention has been described above in terms of a method, and an embodiment of the present invention will be described in detail from the perspective of a device with reference to FIG.

Similar to the foregoing method embodiment, in the embodiment of the device, the policy control device 10 of the fixed access network and the policy control device 20 of the mobile core network exchange cross-domain policy control information, and respectively assist the fixed access network and The mobile core network performs corresponding policy control processing. In this embodiment, the mobile core network sends a service policy configuration request to the fixed access network, and requests a corresponding policy for its service as an example for description. It will be understood that the invention is not limited thereto. Further, the service policy configuration request configures a request for a broadcast and/or multicast service policy, and the fixed access network configures a VLAN and a bandwidth thereof for a multicast service such as broadcast and/or multicast provided by the mobile core network to the mobile device, Delay and other service strategies. It will be understood that the invention is not limited thereto.

As shown in FIG. 4, the mobile network policy control apparatus 20 of the mobile core network includes: a request acquisition apparatus 200, a request transmission apparatus 201, and a response reception apparatus 202. The fixed network policy control device 10 of the fixed access network includes: a request receiving device 100, a processing device 101 and a response device 102.

First, the mobile terminal MS has subscribed to one or more broadcast and/or multicast services, which are represented by the corresponding one or more multicast addresses. The mobile terminal MS accesses the BSR, and the AN to which the BSR belongs has not configured the VLAN for the multicast address. Then, the mobile core network verifies the identity of the mobile terminal or its user and whether it subscribes to the broadcast and/or multicast service, and the IPSec channel established by the BSR and the mobile core network is verified by the HLR (Home Location Register). AAA (authentication, authorization, and accounting) servers are performed.

Policy control device.

The answering device 102 of the fixed network policy control device 10 sends a response to the broadcast and/or multicast service policy configuration request back to the mobile network policy control device. Preferably, the response of the broadcast and/or multicast service policy configuration request is also based on the Diameter protocol, using CEA messages. Unlike the CER message, the "R" bit of the CEA message is set to 0. The network response policy control device 20 receives the response and provides the response to the gateway Brick of the mobile core network for subsequent broadcast and/or multicast services based on the response.

Since the gateway Brick is a functional entity for the mobile core network to send broadcast and/or multicast services to the fixed access network, preferably, in this embodiment, the mobile network policy control device 20 can logically belong to the gateway belonging to the mobile core network. Brick; Further, it can also be physically integrated into the Brick.

Thereafter, when the user of the mobile terminal MS requests to play the multicast service, for example, when requesting to join the multicast group of the corresponding multicast address by using the IGMP protocol, the gateway Brick of the mobile core network controls the broadcast indicated by the device according to the mobile network policy. And/or multicast service policy configuration information, transmitting data of the broadcast and/or multicast service with the corresponding multicast address to the gateway BNG of the fixed access network. The gateway BNG sends the data of the multicast service to the AN in the corresponding VLAN, and provides the data to the mobile terminal MS through the BSR. The multicast communication process in a specific fixed mobile convergence network is well known to those skilled in the art, and the present invention will not be described herein.
