Abstract
The invention discloses a service scheduling method, a service scheduling device and a service scheduling system. The service scheduling method comprises the following steps of: receiving a service property identifier sent by a core network, and converting the service property identifier into corresponding service property data according to a preset mapping relationship list; and scheduling the service according to the service property data. In the invention, the core network informs equipment for executing the service scheduling about the channel associated service property, so that the service scheduling equipment can schedule the service according to the service property so as to improve service executing quality and improve perception of a user. The service property identifier is transmitted but the service property data is not directly transmitted so that the network source is saved, and the service property of an application layer is effectively notified to the equipment for executing the service scheduling in time.

Table 1
In the present embodiment, notify the equipment of carrying out service dispatching with traffic performance with the road, make service dispatching equipment to dispatch each user's business, improve professional implementation quality, improve user's perceptibility according to priority by core net.
And transport service characteristic sign rather than direct transport service performance data have been saved Internet resources, the equipment that can timely and effectively the traffic performance of application layer be notified industry to be engaged in scheduling.
In addition, a lot of operators need obtain and understand the user in the business conduct of zones of different in order to carry out the business diagnosis and the network optimization, for example according to traffic performance data statistics result for the online or the more zone of video stream traffic, carry out the network planning and resource adjustment.
System embodiment
As shown in Figure 4, service scheduling system embodiment of the present invention comprises:
Service dispatching network element 44 is used for being converted to the corresponding business performance data according to the described traffic performance sign that default mapping relations table will receive, and carries out service dispatching according to described traffic performance data.
For the 3G/2G system, core network element 42 can possess the logic entity of identification services ability for GGSN, routing gateway, PDN or other, and described service dispatching network element 44 is RNC.
For the 3G system, is example with core network element 42 with GGSN, service dispatching network element 44 is an example with RNC, as shown in Figure 5, GGSN is at the service attribute of resolving current data stream, after obtaining the traffic performance data, the traffic performance sign is filled in corresponding DSCP position in the GTPU/IP packet header in being handed down to the business datum of SGSN; The business datum that comprises the traffic performance sign that SGSN will receive is transparent to RNC by the DirectChannel technology.RNC obtains the traffic performance sign from the position of data correspondence, is converted to the corresponding business performance data according to the mapping relations table.
For the LTE system, core network element is that EPC or other possess the logic entity of identification services ability, and described service dispatching device is eNB.
In the present embodiment, notify the equipment of carrying out service dispatching with traffic performance with the road, make service dispatching equipment to carry out service dispatching, improve professional implementation quality, improve user's perceptibility according to traffic performance by core net.And, Internet resources have been saved, the equipment that can timely and effectively the traffic performance of application layer be notified industry to be engaged in scheduling by transport service characteristic sign rather than direct transport service performance data.
Device embodiment one
As shown in Figure 4, core network element embodiment of the present invention comprises:
In the present embodiment, the traffic performance data can comprise: the guarantee speed of different business priority or different business or different user are for the priority of same business or the different user guarantee speed for same business.Wherein, service priority or guarantee speed can be divided for the demand of Radio Resource for the perceptibility or the business of different business according to the user.This business corresponding priorities of traffic performance sign expression user.The wherein corresponding relation between traffic performance data and the traffic performance sign, and the position that traffic performance is identified in the packet specifies in said method embodiment, does not repeat them here.
In the present embodiment, by core network element the traffic performance data are converted to the traffic performance sign, by transport service characteristic sign rather than direct transport service performance data, saved Internet resources, can notify the equipment that carries out service dispatching with the traffic performance of application layer timely and effectively.
Device embodiment two
As shown in Figure 4, service dispatching network element embodiment of the present invention comprises:
Carry out with signatory two identical users that ftp downloads and streaming media playing is that example illustrates the service dispatching process.Local resource is 1.6Mbps, and user A carries out the ftp downloading service, and user B carries out video playback business (film source speed is 1Mbps).Under the situation that does not adopt traffic identification, the dispatching priority of user A and user B is identical, service dispatching network element (as RNC or eNB) is in Resources allocation, user A and user B mean allocation local resource, be the throughput that each user can obtain 800kbps, obviously the speed of 800kbps is to satisfy the broadcast demand of user B 1Mbps film source.
Adopting under the scene of the present invention, RNC or eNB obtain active user's applied business type according to the traffic performance sign, and (user A is the ftp business, user B is a video traffic), according to the setting of applied business dispatching priority, promptly the dispatching priority of video traffic (perhaps ensureing speed) is greater than the dispatching priority (perhaps ensureing speed) of ftp business.RNC or eNB distribute more resources for user B in resource allocation, and promptly the video traffic user resources will be greater than ftp user's resource.Thereby make the high video traffic of user's susceptibility better to carry out, improve user's Experience Degree.
In the present embodiment, receive the traffic performance sign that core network element sends, make service dispatching equipment to carry out service dispatching, improved professional implementation quality, improved user's perceptibility according to traffic performance by the service dispatching network element.
It should be noted that: above embodiment is only unrestricted in order to explanation the present invention, and the present invention also is not limited in above-mentioned giving an example, and all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
