Technical field

Embodiments of the present invention relate to network control technologies, and in particular, to a method, a network communication system, and a device for reporting a policy execution result. Background technique

With the continuous development of multicast technology, more and more services are implemented through multicast, such as IPTV (IP Television) services and video on demand services. The existing multicast service is implemented in the traditional access network architecture. As shown in Figure 1, the traditional access network architecture mainly includes: CPE (Customer Premise Equipment), AN (Access Node, access). Nodes, BNG (Broadband Network Gateway), Policy Server, and SP (Service Provider). The CPE is a terminal device that provides users with access to various services, and may be a single terminal device or a home network composed of multiple terminal devices, for example, a PC (Personal Computer), a multimedia phone, and a set top box. Or a home network formed by interconnecting a UE (User Equipment) with an RG (Residential Gateway); the AN is used to provide various access methods for the CPE, for example: DSL (Digital Subscriber Line) Access, WIMAX (Worldwide Interoperability for Microwave Access) access, PON (Passive Optical Network) optical access, etc. Policy Server is used to save policies for each service Information, the policy information may be the multicast rights information of the user, the broadband information of the user access line, and the like; the BNG aggregates the traffic of each AN, and configures the policy information of each service stored in the Policy Server to the corresponding CPE. On AN.

In the network architecture, the policy implementation process of the multicast service is specifically: After the CPE accesses the network, the policy server sends the policy information corresponding to the user of the CPE to the BNG; and the BNG sends the policy information to the CPE. AN; AN receives CPE After the service request is sent, it is determined according to the policy information provided by the BNG whether the service requested by the CPE meets the execution policy included in the policy information.

detailed description

The present invention will be described in detail below with reference to the drawings and specific embodiments.

The method for reporting the execution result of the policy provided by the embodiment of the present invention mainly includes: the AN performs corresponding policy processing on the service according to the policy information of the service, and sends the report message including the execution result of the policy to the BNG.

Further, in order to enable the network side to adjust the policy information of the corresponding service according to the policy execution result, the BNG may send the report message to the Policy Server or other application server after obtaining the report message including the policy execution result. Further one In order to enable the user to know the result of the policy execution, the escalation message may also be sent to the CPE used by the user by the Policy Server or other application server.

The method for reporting the execution result of the policy provided by the embodiment of the present invention is described in detail below by taking the requesting multicast channel as shown in FIG. 2 as an example. The plan includes the following steps:

Step S201: The CPE initiates a service request to the AN.

In this step, the service request initiated by the CPE to the AN includes the requested service identification information.

The CPE device may carry the requested service identification information, such as the requested multicast channel identifier, the multicast group IP address, or the multicast source, in the IGMP join message when the service request is initiated to the AN. , multicast group IP address pair (S, G).

Step S202: After receiving the service request of the CPE, the AN obtains the policy information of the service corresponding to the user of the CPE.

In this step, the AN obtains the user identifier corresponding to the CPE according to the received service request, and obtains the policy information of the service corresponding to the user of the CPE according to the user identifier.

The user identifier may be an Access Circuit Identifier (ACI), and each access line corresponds to a unique ACI; the AN may obtain the ACI of the line by receiving an access line of the IGMP subscription message sent by the CPE.

The policy information table may be pre-stored in the AN. The policy information table is obtained by the BNG in advance from the Policy Server and configured in the AN. The AN searches for the service corresponding to the user of the CPE from the storage policy information table according to the ACI corresponding to the CPE. The policy information of the service corresponding to the user of the CPE is requested by the BNG according to the obtained ACI, and the policy information of the service corresponding to the user of the CPE is obtained by the BNG from the Policy Server, and the policy information is obtained. Provided to AN.

For example, when the policy information of the service is the multicast permission of the service, the AN may pre-store the multicast permission table, and after receiving the multicast request sent by the CPE, find the multicast permission information of the AN according to the obtained ACI.

In addition, when performing real-time services, when the AN performs a push (Push) service, The step of the CPE requesting the AN in the step S201 is not required. In this case, the AN can directly obtain the policy information of the service corresponding to all the access lines, and perform step S203 on all the CPEs.

Step S203: The AN performs corresponding policy processing on the service according to the policy information of the service corresponding to the user of the CPE, and generates a report message that includes the policy execution result.

In this step, the AN determines, according to the service identifier information included in the service request, for example, the multicast channel identifier, whether the user of the CPE has the right to join the multicast channel according to the multicast authority information in the policy information acquired in step S202. And if yes, the multicast stream that is requested by the CPE is sent to the access line of the CPE, and the executed policy execution result is that the policy is successfully executed; if not, the multicast stream requested by the CPE is refused to be delivered to the CPE. On the access line, the generated policy execution result is that the policy execution fails.

The report message that includes the policy execution result in the step may further include at least one of a user identifier, a requested service type, and a detailed description of the requested service. If the policy execution fails, the report message may further include a failure reason. The user identifier may be an ACI identifier, or an IP address identifier of the CPE, and the like; the requested service type may be a multicast service, a unicast service, or the like; and the requested service description may be a requested channel identifier, a multicast group IP address, or the like. Multicast source, multicast source, multicast group IP address pair (S, G), unicast IP address, etc.; policy execution result can be successful or failed; failure reason can be CPE user has no permission or the CPE user does not have Enough access line bandwidth, etc.

The user still requests the multicast channel as an example. If the policy fails because the user does not have enough access line bandwidth to transmit the data of the requested multicast channel, the information contained in the report message can be as shown in Table 1:

Table 1

User ID ACI Service Type Multicast Service Description The multicast channel ID policy execution result fails. The reason for the failure is that there is not enough access line bandwidth. The policy processing may be a policy processing of multicast bandwidth admission control in addition to the policy processing of the multicast rights admission control described above, and the policy processing is used to determine that the current user is used for Whether the multicast line bandwidth is sufficient to support the newly requested multicast channel transmission, or the unicast bandwidth admission control policy processing, which is used to determine whether the current user's line bandwidth for unicast is sufficient to support the newly requested unicast data. Transmission, or other policy processing for user services.

Step S204: The AN sends the report message to the BNG.

In this step, the AN can send the report message to the BNG through the ANCP (Access Node Control Protocol). The ANCP protocol is a protocol that exists in the prior art and runs between the AN and the BNG, and is generally used for reporting of access line status, configuration of an access port, configuration of policy information, etc., and is used herein for ANCP messages. The report is sent in the form of a message, and the protocol is no longer advertised here.

After the step is executed, the BNG obtains the policy execution result included in the report message, and optimizes the performance of the network according to the execution result of the policy. For example, when the policy executed by the BNG fails, the BNG can perform the network on the network in time. Verify and adjust the factors in the network that may cause policy execution failures to optimize network performance. Further, the network may be adjusted according to a specific failure reason, so that the CPE can receive the requested service content normally. For example, because the requested service cannot be obtained because there is insufficient access line bandwidth, the BNG can adjust or reallocate the bandwidth allocated to the CPE corresponding access line according to the failure reason, so that the access line can be normally transmitted. The business requested by the user.

Step S205: The BNG sends the received report message to the Policy Server. In this step, the policy server receives the BNG report policy execution result message, which can be used for the user service statistics function. When the user requests the service policy to fail, the policy server can further analyze the cause of the service request failure and optimize the network service transmission.

In this step, the BNG can pass the COPS (Common Open Policy Service), the Diameter Protocol DIAMETER or other control protocols. The received report message is sent to the Policy Server.

Step S206: The Policy Server sends the content of the reported message to the CPE through the communication mechanism of the application layer.

In this step, the Policy Server can establish an application layer communication mechanism with the CPE. For example, the content of the reported message, such as the policy execution result and the failure reason, can be sent to the CPE through the Hypertext Transfer Protocol (HTTP). , so that the user can know the result and reason of the service that cannot be obtained, so as to adjust the corresponding strategy. For example, when the CPE receives the failure of the policy server to send the multicast channel without the request, the CPE can register with the operator, so that the user of the CPE has the right to join the requested multicast channel.

In addition, the BNG may also send the report message to other application servers, for example, an (EPG Electronic Program Guide) server, etc., and the other application server sends the content of the received report message to the CPE through the communication mechanism of the application layer. .
