Abstract
The present invention discloses service transmission priority scheduling method in multiple service communication system, for reducing user receiving important service time delay. In said invention, before one segment or multiple segment data being transmitted, network side according to attribute or user service requirement level parametric variation to change distributed transmission priority. Said service attribute can be retransmission times or QoS etc, user service requirement level can be expressed by the number of requesting or rejecting service user. Transmission priority change can be realized through changing priority parameter in ARP or keeping ARP unchanged, and through bring service attribute or user service requirement level parameter into transmission priority determinative factor.
Description
Technical field
Priority scheduling technology in the present invention relates to communicate by letter, particularly multi-business communication system medium priority dispatching method.
Background technology
Through nearly fast development decades, the crowd that mobile communication is benefited is more and more wider, but the business that it provided is still based on phone and message.Along with the fast development of internet (Internet), a large amount of multimedia services emerge in large numbers synchronously, and people obviously also require mobile communication also to support multimedia service.The a plurality of users of some multimedia service application requirements that the internet provides receive identical data simultaneously, as video request program, television broadcasting, video conference, online education, interactive game etc., on cable network, can adopt internetworking agreement (Internet Protocol at present, abbreviation " IP ") multicast and broadcast technology realize, but these business are transplanted on the mobile network, compare with general data, because it is big that these business have data volume, longer duration, characteristics such as delay sensitive, and mobile network has the particular network structure, functional entity and wave point etc., existing IP multicast and broadcast technology can not be directly applied for mobile network.
In order to effectively utilize the mobile network resource, realize the application of mobile multi-media service, third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") multimedia broadcast-multicast service (Multimedia Broadcast/Multicast Service has been proposed, be called for short " MBMS "), be used for providing a data source to send the point-to-multipoint service of data to a plurality of users at mobile network.The reference model of MBMS system is compared with conventional system, increased the mobile network functional entity newly, be broadcast multicast service center (Broadcast-Multicast Service Centre, be called for short " BM-SC "), it is content provider's a inlet, be used for authorizing and initiating the MBMS bearer service, and plan transmits the MBMS content to schedule at mobile network.In addition, other related functional entities also strengthens in the network, has increased the relevant function of MBMS.The MBMS of 3GPP definition can not only realize the classes of messages broadcasting and the multicast of plain text low rate, and can also realize the broadcasting and the multicast of high-speed multimedia business.
The entire flow that the user receives certain MBMS broadcasting service at first is service statement (Service announcement) as shown in Figure 9, notifies user MBMS the relevant information of business; Next be that session begins (Session Start), BM-SC is ready for sending data; Be MBMS notice (Notification) then, radio network controller (Radio Network Controller is called for short " RNC ") is notified user MBMS muticast data transmission; Follow by data transmission procedure; Be conversation end (Session Stop) at last, BM-SC has not been ready for sending data, and bearing resource can discharge.The entire flow that the user receives certain MBMS multicast service is compared with the broadcasting flow process as shown in figure 10, and multicast pattern needs user's corresponding multicast group of contract, carries out activation of service, and produces corresponding charge information, so its operation flow is with to broadcast flow process different.Increase signatory (Subscription) step among Figure 10, set up the contact between user and the service supplier; Increased simultaneously user's adding (joining) step after service announcement step, promptly the user notification network prepares to receive the MBMS business; Correspondingly after the conversation end step increased the user and withdraw from (leaving) step, the user no longer has been the member of MBMS multicast group, and other step is consistent with the broadcasting flow process.
MBMS is when the multicast of specific implementation media business and broadcasting, and MBMS point-to-multipoint service channel (MBMS Point-to-Multipoint Traffic Channel is called for short " MTCH ") is the MBMS service transmission channel, has carried the particular content of MBMS business.The transmission of MBMS business is to carry out according to session (Session), and promptly a business is divided into a plurality of session and transmits, and each session is exactly a section business content.Adopt the session technology can make things convenient for the re-transmission of application layer, thereby guarantee the delivery quality of multimedia service.
Usually in order to guarantee the transmission of a plurality of multimedia services when multicast and the broadcasting better, also need to provide the priority control of different business, prior art has taked following means to realize priority control to this: by core net (Core Net, be called for short " CN ") according to its service quality (Quality of Service, abbreviation " QoS ") characteristic is given method that is used to specify priority between the different business of MBMS traffic assignments, promptly distribute and preferential (the Allocation and Retention Priority of maintenance, be called for short " ARP ") rank, at the Iu interface is that different business distributes RAB (Radio Access Bearer, be called for short " RAB ") time need be with reference to this ARP value, UE equally also within it portion be different MBMS business and MBMS is professional and non-MBMS business between definite priority.But priority of the prior art control has significant limitation, and according to prior art, network side can't be according to the different qualities of this professional different time sections, or the different time sections user has the variation of different business demands to adjust priority level.In general, network side should change or receive and react to some extent when professional number of users changes at professional self character, changes with respect to the priority of original distribution because these change the actual priority that all can cause different business.If each professional priority level can not adapt to this variation, will provide professional QoS to network so, and user's satisfaction causes bigger influence.Therefore improving prior art seems very urgent to overcome its limitation.
Summary of the invention
In view of this, main purpose of the present invention is to provide the dispatching method of professional transmission priority in a kind of multi-business communication system, and the time delay that makes the user receive important service reduces.
For achieving the above object, the invention provides the dispatching method of professional transmission priority in a kind of multi-business communication system, the network side of described system is priority of each traffic assignments, described multi-business communication system is the multimedia broadcast/group broadcast service system, and described method also comprises following steps:
Before one or more snippets data of business were transmitted, described network side judged whether attribute that this is professional and/or expression user to the parameter of this business demand degree variation have taken place, and has been the transmission priority of this traffic assignments if then change.
Wherein, the attribute of described business is the number of times that described one or more snippets data are retransmitted, or the service quality of this segment data.
In addition, described expression user to the parameter of business demand degree can be:
Send number of users, or send number of users this service denial information to this business demand information.
In addition, can change the transmission priority of described business in the following manner:
Revise the distribution of this business and the priority parameters in the maintenance priority, determine described transmission priority by this parameter.
In addition, can change the transmission priority of described business in the following manner:
According to preset rule, determine this professional transmission priority jointly by the combination of following information:
Each parameter in the distribution of this business and the maintenance priority is comprising priority parameters; With,
The attribute that this is professional.
In addition, can also change the transmission priority of described business in the following manner:
According to preset rule, determine this professional transmission priority jointly by the combination of following information:
Each parameter in the distribution of this business and the maintenance priority is comprising priority parameters; With,
The expression user is to the parameter of this business demand degree.
In addition, described data are sessions professional in the multimedia broadcast/group broadcast service system, can determine the number of retransmissions of session in the following manner:
" session repetition number " attribute by session is determined; Perhaps,
The number of transmissions reckoning by session identification obtains.
In addition, when change has been the transmission priority of described traffic assignments, can improve or reduce this professional transmission priority according to preestablishing.
In addition, described method is applicable to broadband CDMA system, CDMA 2000 system or TDS-CDMA system.
By relatively finding, the main distinction of technical scheme of the present invention and prior art is, before one or more snippets data of business are transmitted, network side is according to service attribute or represent the situation of change of user to the parameter of this business demand degree, and changing has been the transmission priority of this traffic assignments.
Service attribute can be the number of times that retransmits or QoS etc., and the user can represent by request or the professional modes such as number of users of refusal the desirability of business.
The change of transmission priority can realize by the priority parameters that changes among the ARP, also can be by keeping the priority parameters among the ARP constant, the decisive factor of the parameter of this business demand degree being included service attribute or expression user in transmission priority realizes.
Difference on this technical scheme, brought comparatively significantly beneficial effect, promptly because transmission priority can change the business demand degree change with service attribute or user, so can make limited Internet resources preferentially offer the business of most important (user needs most in other words), Resource Allocation in Networks is more reasonable, the time delay that the user receives important service reduces, and user's satisfaction improves.
Shifting gears of two kinds of transmission priorities makes the present invention more flexible when specific implementation, can satisfy the various constraintss of real system, and for example some system may require the priority parameters among the ARP to change.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
For first and second embodiment that below will describe, their something in common is described at first.
At first, CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.The technology of this distribution ARP priority is a prior art, and one of ordinary skill in the art can both realize, does not do at this and gives unnecessary details.After this, when this communication service with respect to former relativity variation has taken place in the relativity of the number of retransmissions characteristic of certain time period and other communication services, then CN is ARP priority of this traffic assignments again.
Specifically, Fig. 1 shows the first embodiment of the present invention, and as shown in the figure, the dispatching method of this business transmission priority comprises following steps:
Step 110:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.
Step 120: belong to the transmission again of certain business when communication service in certain time period, that is to say, it is the transmission again of one or more Session of certain communication service, then CN reduces a rank with the ARP priority of this communication service, and, number of retransmissions is many more, and the rank that ARP priority reduces is many more.The reduction and the relation between the number of retransmissions of ARP priority can be provided with according to actual needs flexibly.One of ordinary skill in the art can be understood, in this case, can judge, in each communication service of needs transmission, the professional ARP priority that number of retransmissions is low higher (so the reason that is provided with may be that this system thinks that the lower communication service of number of retransmissions is the business of outbalance), thereby the business that transmission priority is higher, present embodiment retransmits professional ARP priority by reducing, guarantee to allow the important service prioritised transmission, thereby the user who reduces important service accepts the time delay of this important service.And, adapt to the variation of professional and user's request preferably, make Resource Allocation in Networks more reasonable, improved user's satisfaction.
The number that professional session retransmits can be differentiated by Session repetition number (session repetition number), also can calculate out by the number of transmissions of session id (session identification).
Fig. 2 illustrates the dispatching method of professional transmission priority according to a second embodiment of the present invention, comprises following steps:
Step 210:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.
Step 220: the one or more Session that belong to certain business in certain time period when communication service transmit again, and then CN is the ARP priority of this communication service rank that raises, and number of retransmissions is many more, and the rank of rising is many more.In the present embodiment, as mentioned above, the relation in the rising of ARP priority and the business between the number of retransmissions of one or more session can be provided with according to actual needs flexibly.Opposite with first embodiment, can judge that in this case important service should be the high business of those number of retransmissions, because retransmit professional ARP priority by rising in the present embodiment, improve transmission priority, guarantee to allow these professional prioritised transmission, thereby the user who reduces important service receives the time delay of this important service.And, adapt to the variation of professional and user's request preferably, make Resource Allocation in Networks more reasonable, improved user's satisfaction.
More than Shuo Ming example is the situation of priority with the number of retransmissions monotone variation, also has other situation in the practice.For example, a kind of situation is, the priority that retransmits raises for the first time, and for the second time or later re-transmission priority reduces on the contrary.And for example, for the first time the priority that retransmits reduces, and for the second time or later re-transmission priority raises on the contrary.Priority all belongs to concrete business rule with the mode that number of retransmissions changes, and can be provided with flexibly according to user's actual needs, and technical scheme of the present invention does not have any restriction to this.
For third and fourth embodiment that below will describe, at first summarize their core content.At CN is after ARP priority is distributed in communication service, when this communication service with respect to former relativity variation has taken place in the relativity of the number of retransmissions characteristic of certain time period and other communication services, it is constant that then CN keeps this professional ARP priority, meanwhile, when carrying out each professional transmission priority, consider the situation of change of this business number of retransmissions, adjust transmission priority.
Specifically, as shown in Figure 3, the dispatching method of the of the present invention the 3rd professional transmission priority of implementing comprises following steps:
Step 310:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.As mentioned above, the technology of this distribution ARP priority is a prior art, and one of ordinary skill in the art can both realize, does not do at this and gives unnecessary details.
Step 320: belong to the transmission again of certain business when communication service in certain time period, it is constant that then CN keeps this professional ARP priority, meanwhile, when each professional transmission priority of decision is other, the characteristic that needs this business of consideration to change, be the characteristic of number of retransmissions, its transmission priority is reduced to is lower than other business with identical ARP priority.Specifically, comprise different parameters among the ARP, for example above-mentioned " ARP priority ", " whether can seize " etc.Increased a parameter in the present embodiment: " number of retransmissions ".Network side is when handling the transmission priority of communication service, with the value concrete analysis of comprehensive above-mentioned each parameter.For example, if ARP priority is 2, as if should be 3 back biography in principle than ARP priority, but consider other parameters of ARP, for example " number of retransmissions ", then might ARP priority be that the transmission priority of 2 communication service is higher than the transmission priority that ARP priority is 3 communication service, specifically can determine by network side.In the present embodiment, can so be provided with: in the identical various communication services of ARP priority, the parameter of ARP " number of retransmissions " is many more, and then final professional transmission priority is low more.So the reason that is provided with may be that this system thinks that the lower communication service of number of retransmissions is the business of outbalance.In this case, reduce the user's of these important service receive time delay in the present embodiment by prioritised transmission.And this method can adapt to the variation of professional and user's request preferably, makes Resource Allocation in Networks more reasonable, has improved user's satisfaction.
This shows, in the present embodiment, by not changing ARP priority, and change other parameters of ARP, change priority.That is to say, will participate in the priority decisions of final communication service such as other parameters of ARP such as " number of retransmissions ".
Fig. 4 illustrates the professional transmission priority dispatching method of a fourth embodiment in accordance with the invention, as shown in the figure, comprises following steps:
Step 410:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.As mentioned above, the technology of this distribution ARP priority is a prior art, and one of ordinary skill in the art can both realize, does not do at this and gives unnecessary details.
Step 420: belong to the transmission again of certain business when communication service in certain time period, it is constant that then CN keeps this professional ARP priority, meanwhile, when each professional transmission priority of decision, needs are considered the characteristic of number of retransmissions, its transmission priority are elevated to be higher than other identical business of ARP priority.In the present embodiment, can so be provided with: in the identical various communication services of ARP priority, the parameter of ARP " number of retransmissions " is many more, and then final transport service priority is high more.In this case, illustrate that the higher communication service of number of retransmissions is the business of outbalance, reduce the user's of these important service receive time delay in the present embodiment by prioritised transmission.And, can also adapt to the variation of professional and user's request preferably, make Resource Allocation in Networks more reasonable, improved user's satisfaction.
Present embodiment and the 3rd embodiment be in fact based on identical principle, and difference is, at the increase of the parameter " number of retransmissions " of ARP, adjusts priority to height for one, and one to the low priority of adjusting.Equally also be by keeping ARP priority constant in fact, and other parameters that change ARP reach the purpose that changes professional transmission priority according to actual conditions flexibly, will participate in such as other parameters of ARP such as " number of retransmissions " in the transmission priority decision-making of final communication service.
For the 5th and the 6th embodiment that below will describe, same, their core is described by elder generation.At CN is after ARP priority is distributed in communication service, if change for the reception or the refusal requesting users number of this business, then CN will adjust the ARP priority of this business correspondence according to user's request situation, thereby dispatch this professional transmission priority.In the present invention, the business that the user sends receives or the refusal request, can pass through dedicated channel, also can send by common signal channel.
Specifically, as shown in Figure 5, in according to a fifth embodiment of the invention, comprise following steps:
Step 510:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.
Step 520: increase (or it is less to refuse this professional number of users) when what send for the reception requesting users number of this business, CN this professional ARP priority that will raise then, promptly CN is higher ARP priority of this communication service distribution again.In the present embodiment, increase the variation that this user asks at number of users, as mentioned above, CN adjusts the ARP priority of communication service, thereby improves this professional transmission priority according to situation of change.Be appreciated that, in an embodiment, if the reception requesting users number of a communication service is more, then this business is the business of outbalance, improve their transmission priority by improving these professional ARP priority, thereby allow these business can prioritised transmission, reduced user's receive time delay.And this method can adapt to the variation of professional and user's request preferably, makes Resource Allocation in Networks more reasonable, has improved user's satisfaction.
Fig. 6 shows the dispatching method of the transmission priority of business according to a sixth embodiment of the invention, and the method includes the steps of:
Step 610:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.
Step 620: when the refusal requesting users number that sends more (or sending the request number of users of this business less) for this business, then CN will to reduce this professional transmission priority other by reducing this professional ARP priority, and promptly CN is low-level transmission priority of this traffic assignments again.This shows, in the present embodiment, the business of outbalance should be the less business of those refusal requesting users numbers, by reducing the ARP priority of the more business of refusal requesting users number, improve the transmission priority of the business of outbalance, guarantee that they can prioritised transmission, thereby reduced user's propagation delay time.And, adapt to the variation of professional and user's request preferably, make Resource Allocation in Networks more reasonable, improved user's satisfaction.
The the 7th and the 8th embodiment:
For the 7th and the 8th embodiment that below will describe, their core is described at first.At CN is after ARP priority is distributed in communication service, when receiving number of users professional or that refusal is professional, request changes, it is constant that then CN keeps the ARP priority of this business session correspondence, meanwhile, when carrying out each professional transmission priority, need to consider other attached characteristic of this business, just other parameters of ARP.
Specifically, as shown in Figure 7, professional transmission priority dispatching method according to a seventh embodiment of the invention comprises following steps:
Step 710:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.
Step 720: increase when request receives professional number of users, it is constant that then CN keeps the ARP priority of this business session correspondence, meanwhile, and when carrying out each professional transmission priority, consider other ARP parameters of this business, such as " request receives professional number of users " of this business.In the present embodiment, the number of users of supposing the request reception of some business increases, can think that then this business is the business of outbalance, CN will be when the ARP priority that keeps this business session correspondence be constant, consider another ARP parameter: " request receive professional number of users ", CN will be by this ARP parameter that raises this professional transmission priority that raises.Thereby guarantee that this business can have precedence over the identical communication service transmission of other ARP priority, reduces the user and receives this professional propagation delay time.And, adapt to the variation of professional and user's request preferably, make Resource Allocation in Networks more reasonable, improved user's satisfaction.
Fig. 8 illustrates the professional transmission priority dispatching method according to the eighth embodiment of the present invention, as shown in the figure, comprises following steps:
Step 810:CN is according to the characteristics such as QoS of each communication service, for this communication service distributes an ARP priority.
Step 820: the number of users professional when the request refusal increases, it is constant that then CN keeps the ARP priority of this business session correspondence, meanwhile, when carrying out each professional transmission priority, need to consider other ARP parameters of this business, such as " the professional number of users of request refusal " of this business.In the present embodiment, the number of users of supposing the request refusal of some business increases, can think that then this professional importance is lower than the business that other have identical ARP priority, therefore, CN will be when the ARP priority that keeps this business session correspondence be constant, consider another ARP parameter: " the professional number of users of request refusal ", CN will be reduced to this professional transmission priority by this ARP parameter that raises and be lower than the business that other have identical ARP priority.Thereby guarantee that other are more importantly professional prior to this business transmission, reduce the user and receive more importantly professional propagation delay time.And, adapt to the variation of professional and user's request preferably, make Resource Allocation in Networks more reasonable, improved user's satisfaction.
In addition, it is pointed out that in other embodiments of the invention, also can adopt another parameter among the ARP " whether to seize ".Specifically, whether " the whether seizing " parameter according to ARP is that " very " judges with ARP priority still to be to determine professional priority with " number of retransmissions ".For example, if this parameter is " very ", then CN determines professional priority with ARP " number of retransmissions ", otherwise determines professional priority with ARP priority.
Though be familiar with persons of ordinary skill in the art may appreciate that above each embodiment describes is the situation of MBMS, also can be applied to the situation that other multi-service is communicated by letter with not adding any creative work.Can use the multi-business communication system of this method to include but not limited to Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, abbreviation " WCDMA ") system, CDMA 2000 (Code Division Multiple Access 2000, be called for short " CDMA2000 ") system and TD SDMA (Time Division Synchronous Code Division MultipleAccess is called for short " TD-SCDMA ") system etc.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
