An embodiment of the present invention provides a method for setting a media priority, which not only can It can be applied to IP bearer network, and can also be applied to other networks, such as Asynchronous Transfer Mode (ATM) multi-service data network and Voice over Internet Protocol (VoIP) service network; A method of how to use the set priority to send business data. The following two aspects are explained separately.

For the method of setting the media priority, the IP bearer network is used as an example. The principle is the same in other networks, and the description is not repeated.

A method for setting a media priority based on an IP bearer network according to an embodiment of the present invention includes: setting a service priority according to a service type and user subscription data, and transmitting media data on the IP bearer network by using the service priority. The foregoing subscription data may be a Cs-Allocation Retention Priority (CARP), an Enhanced Multi-Level Precedence and Preemption (eMLPP), or a user category; the foregoing service types include voice services, fax services, Data service or video phone (VP) service. The specific operation of transmitting the media data on the IP bearer network by using the service priority may be: transmitting the service priority between the mobile switching center servers, and sending the service priority to the media gateway, where the media gateway uses the service Priority sets the prioritization of the media stream.

The following is an example to describe the method for determining the service priority. The user's service is the voice service at this time. The subscription data at this time is eMLPP. The operation of determining the service priority according to the service type and the priority of the initiator may be After receiving the call request from the initiator, the originating mobile switching center server sets the priority of the initiator according to the voice service and the initiator's eMLPP determination algorithm, and determines the priority of the initiator as the service priority. , the originator's MSC Server will the service The priority is passed to the MSC Server of the receiver and the MGW of the initiator, and the MSC Server of the receiver transmits the service priority to the MGW of the receiver. The operation of determining the service priority according to the priority of the voice service and the receiver may be that after the initiator's mobile switching center server receives the call request of the initiator, the initiator's MSC Server transmits the receiver's information to the receiver. The MSC Server of the party determines the eMLPP of the receiver by the information of the receiver, and determines the priority of the receiver according to the voice service and the eMLPP of the receiver, and the MSC Server of the receiver sets the priority of the receiver as the service priority. Level, and deliver the service priority to the receiver's MGW and the initiator's MSC Server, and the initiator's MSC Server sends the service priority to the MGW. The comparison determines the priority of the high level as the business priority or determines the lower priority by the above comparison as the business priority.

Setting the service priority of the media stream; the initiator's MSC Server sets the priority of the initiator with the received service priority, and sends the service priority to the initiator's MGW. The initiator's MGW uses the received service priority. The level sets the service priority of the media stream. The operation of the MSC Server of the above-mentioned initiator may also be replaced by the following method: the initiator's MSC Server sends the initiator's priority to the initiator's MGW, and the initiator's MGW uses the initiator's priority. The service priority of the media stream is set first; if the service priority received by the MSC Server is the initiator priority, the service priority is not sent.

The specific operation of sending the determined service priority to the initiator MSC Server in the foregoing operation may be that the receiving MSC Server passes the determined service priority through an Address Complete Message (ACM) or a call response (Answer Message, ANM) is sent to the originator's MSC Server.

The specific operation of sending the calling/called priority to the MGW may be that the calling/receiving MSC Server sets the priority of the calling/receiver by extending the H.248/Media Gateway Control Protocol (Media Gateway). The ADD Req message of the Control Protocol, MGCP) is sent to the media gateway of the calling/receiver.

The specific operation of the ADD Req message of the extended H.248/ MGCP may be to extend the priority of the H.248 message processing, and the value range of the priority INTEGER (0...15) OPTIONAL message (0... 15) Extended to (0...65535) and applied to the priority of the media stream, the service priority may also add a newly defined priority to the message to deliver the service priority.

The other aspect provided by the embodiment of the present invention is how to use the set priority to perform service data transmission.

The method for transmitting service data in the embodiment of the present invention can be applied to various communication networks, for example, an IP bearer network, an Asynchronous Transfer Mode (ATM) multi-service data network, and a Voice over Internet Protocol (VoIP). Service networks, etc., the service data in these communication networks are pre-set with different priorities, and the routers in the network send corresponding service data according to the priority. In the following embodiments, the IP bearer network is taken as an example for description. The principle of transmitting service data in the IP bearer network by using the technical solution of the embodiment of the present invention is the same as the principle of transmitting service data in other communication networks. The business data may include connection-oriented or user-oriented data, such as service data transmitted by the connection or the user in units of streams, and may also include data of single or multiple messages.

Embodiment 6: A method for transmitting service data, see FIG. 6, the method includes:

601. When the QoS indicator is degraded, the priority of the service is lowered.

The QoS indicator is degraded, that is, the network is congested. Specifically, the lower limit value of the QoS value may be set in advance. When the QoS value of the transmission service data path is lower than the lower limit value, the QoS indicator is degraded, wherein the QoS value may be based on A comprehensive evaluation of the delay, packet loss, and jitter of the transmitted service data is obtained.

If the QoS metrics are degraded, you can learn whether the QoS metrics of all services are degraded, or whether the QoS metrics of the highest priority service are degraded. In both cases, the principles of the methods are the same. The device that sends the service data knows by detecting or receiving the detection result from other detection devices, wherein the service data needs to be sent. Equipment can include, but is not limited to, network devices such as media gateways, switches, and routers:

1. The QoS indicator can be directly detected by the device that needs to send the service data, and the detected QoS indicator is compared with the lower limit value of the QoS value. If the QoS index is higher than or equal to the lower limit value, the QoS indicator is not degraded; if the QoS value is low At the lower limit, the QoS indicator deteriorates.

2. The detection result of the QoS indicator degradation of the service data from the network or the detection system may also be received by the device that needs to transmit the service data.

Lowering the priority of a service can lower the priority of some services according to the priority policy. The priority policy may include, but is not limited to, a percentage, a user priority, a service priority, or an office priority. According to the priority policy, the priority of some services is reduced, thereby alleviating congestion and ensuring QoS of high-priority services.

For example, in an IP bearer network, the identification method of the Differentiated Service (DifFserv) tag is used to distinguish the priority of the service. The Diffserv tag includes but is not limited to Expedited Forwarding (EF) tag, Assured Forwarding (AF). Marking and Best Effort (BE) mark, Diffserv Code Point (DSCP) service data marked as Expedited Forwarding (EF) is forwarded as soon as possible, such as voice service data; DSCP is marked as Ensure that the service data of the Assured Forwarding (AF) is guaranteed not to be lost during the forwarding process, such as signaling service data. The DSCP is marked as best-effort (Best Effort, BE) service data, and the packet is lost if it cannot be forwarded. For example, network management billing business data. When the QoS indicator of the service data is degraded, the EF flag in the service data marked by the EF may be switched to the BE mark or the AF mark, or the AF mark in the service data of the part of the AF mark may be switched to the BE mark.

Further, reducing the priority of the service may only lower the priority of some services in the service with the highest priority, thereby alleviating the congestion state and ensuring the QoS of the high priority service.

For example, in the IP bearer network, when the QoS indicator is degraded, part of the EF marked service data may be set as the service data of the BE mark or the AF mark.

602. Send service data according to the reduced priority.

After the QoS indicator is degraded, the devices at both ends of the service data may reduce the priority of the service data, or only one device may lower the priority of the service data. Therefore, the lowest priority among the reduced priorities may be determined. Level, according to the lowest priority, send business data. Further, while reducing the priority of the service, the codec with stronger anti-dropping capability or smaller bandwidth overhead may be selected to replace the current codec, and the switched service data is obtained. The switched service data is sent according to the reduced priority, thereby further improving the QoS of the service while alleviating the congestion state.

When the QoS indicator of the network is further deteriorated, the connection access control is used to reject the access of part of the service data, thereby controlling the amount of service data entering the network. Specifically, when the service corresponding to the service data is a call, the new call may be rejected. It is also possible to reject some new calls, reject new calls and partial online calls, or reject some new calls and partial online calls.

The method for determining whether the QoS indicator of the network is further deteriorated may be as follows: determining whether the proportion of the service with the highest priority in the service is less than the threshold, and if the proportion of the service with the highest priority in the service is less than the threshold, the QoS indicator of the network is determined. Further deterioration; if the proportion of the highest priority service in the service is greater than or equal to the threshold, it indicates that the QoS indicator of the network has not deteriorated further.

Rejecting access to part of the service data may be based on a denial policy, which may include, but is not limited to, percentage, user priority, service priority, or office priority.

When the QoS indicator is degraded, that is, when the network enters the congestion state, the priority of the service is reduced, and the service data is sent according to the reduced priority, thereby ensuring the service quality of the high-priority user and ensuring that the low-priority user is connected. The impact of network congestion on users is relatively mild and smooth, improving the stability of service quality when the network is congested. Further, the priority of the service may include, but is not limited to, the priority of the flow or the priority of the packet. When the priority of the service is the priority of the flow, the priority is reduced by the flow, and the network congestion is relieved, and the operation is simpler.

Correspondingly, when the QoS indicator improves, the priority of the service can be restored. The process of recovery is the opposite of the process of reduction. For example, when the service with the highest priority in the service is the voice stream of the call, and the ratio of the service with the highest priority in the service is F, the proportion of the service with the highest priority in the service is greater than or equal to F, and when the QoS indicator is improved, the service priority is gradually restored according to the improvement of the QoS indicator; when the proportion of the service with the highest priority in the service is less than F, the call is gradually accessed, and as the QoS indicator improves, Further, when the proportion of the service with the highest priority in the service is greater than or equal to F, the priority of the service is gradually restored according to the improvement of the QoS indicator.
