Embodiment
In order to meet the demand of user to service rate otherness, in the embodiment of the present invention, propose the method for a kind of downstream rate difference scheduling, the method is: base station is by receiving radio network controller (RadioNetwork Controller, the message of transmission when RNC) filtering out the user needing to carry out difference scheduling, and corresponding scheduling strategy is performed to each user needing difference to dispatch; RNC filters out the user needing difference to dispatch, and informing base station performs corresponding scheduling strategy to the user that each needs difference to dispatch.
Illustrate below in conjunction with accompanying drawing and the preferred embodiment of the present invention is described in detail.
Consult shown in Fig. 1, in the embodiment of the present invention, the general introduction flow process of the downstream rate difference scheduling of base station side is as follows:
Step 100: base station receives the reconfiguration message that RNC sends, wherein, reconfiguration message is that customer identification information that RNC passes through to preset sends to base station when filtering out the user needing to carry out difference scheduling, and is marked with the scheduling identification that respective user presets in reconfiguration message.
In the embodiment of the present invention, when performing step 100, difference dispatched users RM is various, can by the international mobile subscriber identification code of user (International Mobile Subscriber Identity, IMSI) a certain user is identified, can according to the user of a certain terminal type of type identification identification of terminal, also the Mean Speed can added up by Access Network side distinguishes user, and core-network side detects that the type of service of user distinguishes the user type needing difference to dispatch.Applicable surface is large, applied range.Namely RNC filters out based on any one mode in user ID, terminal type identification, the descending Mean Speed of user and the class of business preset the user needing to carry out difference scheduling.
Wherein, the user ID preset can be characterized by IMSI number, and terminal type identification can be passed through international mobile station equipment mark code (International Mobile station Equipment Identity, IMEI) number and characterize.
Concrete, difference scheduling mode can only arrange wherein a certain, and also can arrange multiple, if all arrange, RNC judges that the order that certain user dispatches the need of difference is as follows:
First being judge IMSI number, is secondly judge IMEI, is again to judge the descending Mean Speed of user, is finally detect based on class of business.
If when certain user meets four kinds of modes simultaneously, but after coming into force according to detection before detection ordering, subsequent detection is no longer carried out, and namely the IMSI of certain user is provided with difference scheduling, then do not carry out other mode difference follow-up scheduling and judge; IMEI and Mean Speed similar.If do not meet, then difference is not needed to dispatch.
Wherein, when judging IMSI and IMEI, because IMSI and IMEI is default concrete number, the IMSI or the IMEI that obtain user after each user access network are directly compared, and can determine the user needing to carry out difference scheduling.
Judge the descending Mean Speed of user: be that the descending Mean Speed of each user that RNC administers self judges, when the descending Mean Speed of user reach default need difference dispatched users descending Mean Speed threshold value time, be defined as the user needing to carry out difference scheduling.
Here, the descending Mean Speed of user can according to counting on user IU mouth PDCP (Packet Data Convergence Protocol in the cycle, PDCP) total amount of data and rate detection cycle calculate, and e.g., can adopt formula one calculating:
Descending Mean Speed=count on user IU mouth PDCP total amount of data/rate detection cycle (formula one) in the RNC cycle
When after the normal access network of user, RNC initiates periodic rate detection to each user.If the descending Mean Speed calculated reaches default need the descending Mean Speed threshold value of difference dispatched users, then think that this user needs to carry out difference scheduling.
Such as, user's Mean Speed higher than preset need difference dispatched users descending Mean Speed threshold value time, think that user rate demand is high, can arrange and improve user scheduling frequency and reach the network rate promoting large rate users, improve the perception of large speed, promote network throughput; Or think when user's Mean Speed is too high that this CU resource is too much, this user can be suppressed the use of network unlimited resources by delay dispatching; Embody rule mode can be arranged flexibly according to network demand.
Detect based on class of business: the user expection of certain class service application being met to network average level, preset such class of business detection mode (needing core net to coordinate) and difference scheduling ratio, if it is consistent with difference detection configuration information that core net RNC carries detection letter, then think that this user needs to carry out difference scheduling.
Further, the combination of difference scheduling mode that respective user presets and difference scheduling proportionality coefficient is marked with in reconfiguration message.
Step 110: the user that base station needs difference to dispatch for each, respectively according to the scheduling identification of correspondence, performs corresponding scheduling strategy.
In the embodiment of the present invention, when performing step 110, if the difference scheduling mode of user preset is priority scheduling, then base station is by presetting difference dispatching cycle and descending scheduling cycle, calculate the scheduling times in difference dispatching cycle, then calculate the number of times of preferentially jumping the queue in difference dispatching cycle based on scheduling times and difference scheduling proportionality coefficient, and the number of times of preferentially jumping the queue calculated is distributed in difference dispatching cycle and dispatches.
Such as, base station side presets difference dispatching cycle for being X, and X=100ms, the descending scheduling cycle is that 5ms (generally fix by this cycle, default difference is set to the integral multiple in descending scheduling cycle dispatching cycle), then can calculate the scheduling times of user within a difference dispatching cycle, mark with Y, i.e. Y=X ÷ 5=100 ÷ 5=20
If difference scheduling proportionality coefficient is R=0.2, then formula two can be utilized to calculate the number of times of preferentially jumping the queue in difference dispatching cycle:
Z=R × Y (formula two)
Wherein, Z represents the number of times of preferentially jumping the queue in difference dispatching cycle, and R represents difference scheduling proportionality coefficient, and Y represents the scheduling times in the difference dispatching cycle.
So, by R=0.2, Y=20, draw Z=0.2 × 20=4, namely need preferentially to jump the queue within the difference dispatching cycle of 100ms and dispatch the data of this user for 4 times.
Further, when priority scheduling, can adopt but be not limited to following two kinds of modes:
First kind of way: the number of times of preferentially jumping the queue calculated is randomly dispersed in difference dispatching cycle and dispatches.
The second way: the number of times of preferentially jumping the queue calculated is distributed in difference dispatching cycle according to specific mode and dispatches.
Concrete, frame number skew is set by the data of the user for needing difference to dispatch, and based on the number of times of preferentially jumping the queue calculated, the data of user is distributed in current scheduling queue according to specific mode and dispatches;
Such as, X=100ms, during R=0.2, for the user needing priority scheduling, in data transmission procedure, in every 100ms difference dispatching cycle, random preferential is jumped the queue: first search the user dispatched a little during base station scheduling data, 4 frame data after its scheduling queue are put into foremost scheduling, other data of this user are by original Queue sequence transmission; Evenly preferentially jump the queue: in 100ms, every 25ms data this user being needed to jump the queue after user data queue are placed on queue foremost and transmit.The data that priority scheduling completes, receive after receiving side data is transmitted confirmation at transmit leg, can send new data immediately and transmit, reduce acknowledge time delay in transmitting procedure, therefore user rate can promote.
If the difference scheduling mode of user preset is delay dispatching, then base station is by presetting difference dispatching cycle and descending scheduling cycle, calculate the scheduling times in difference dispatching cycle, then calculate based on scheduling times and difference scheduling proportionality coefficient the number of times carrying out in difference dispatching cycle postponing to jump the queue, and the number of times that the delay calculated is jumped the queue is distributed in difference dispatching cycle and dispatches.
Such as, base station side presets difference dispatching cycle for being X, and X=100ms, the descending scheduling cycle is that 5ms (generally fix by this cycle, default difference is set to the integral multiple in descending scheduling cycle dispatching cycle), then can calculate the scheduling times of user within a difference dispatching cycle, with Y mark, i.e. Y=X ÷ 5=100 ÷ 5=20;
If difference scheduling proportionality coefficient is R=0.2, formula two then can be utilized to calculate carry out in difference dispatching cycle the number of times postponing to jump the queue, by R=0.2, Y=20 brings formula two into, draw Z=0.2 × 20=4, namely need to postpone to jump the queue to dispatch the data of this user for 4 times within the difference dispatching cycle of 100ms.
Further, when delay dispatching, can adopt but be not limited to following two kinds of modes:
First kind of way: the number of times that the delay calculated is jumped the queue is randomly dispersed in difference dispatching cycle and dispatches.
The second way: the number of times of the delay calculated being jumped the queue is distributed in difference dispatching cycle according to specific mode and dispatches.
Concrete, frame number skew is set by the data of the user for needing difference to dispatch, and based on the number of times that the delay calculated is jumped the queue, the data of user is distributed in current scheduling queue according to specific mode and dispatches.
Such as, X=100ms, during R=0.2, for the user needing delay dispatching, in data transmission procedure, in every 100ms difference dispatching cycle, random delay is jumped the queue: first search the user dispatched a little during base station scheduling data, be put into by 4 frame data after its scheduling queue and backmost dispatch, other data of this user are by original Queue sequence transmission; Uniform delays is jumped the queue: in 100ms, and every 25ms data this user being needed to jump the queue after user data queue are placed on queue and backmost transmit.The data that delay dispatching completes, only receive after receiving side data is transmitted confirmation at transmit leg, just can send new data and transmit, time delay in transmitting procedure can be elongated by delay dispatching, therefore user rate can reduce.
Illustrate that RNC screens the user needing difference to dispatch below in conjunction with a concrete application scenarios, consult shown in Fig. 2.
Step 200:RNC obtains the IMSI number of user.
By this IMSI number, step 201:RNC judges that user dispatches the need of difference.

Step 202:RNC informing base station performs difference scheduling strategy.
Step 203:RNC obtains the IMEI of user.
By this IMEI, step 204:RNC judges that user dispatches the need of difference.
If so, then step 202 is performed, otherwise, perform step 205.
Step 205:RNC calculates the descending Mean Speed of user.
By the descending Mean Speed of this user, step 206:RNC judges that user dispatches the need of difference.
If so, then step 202 is performed, otherwise, perform step 207.
Step 207:RNC obtains the class of business of user.
By the class of business of this user, step 208:RNC judges that user dispatches the need of difference.
If so, then step 202 is performed, otherwise, perform step 209.
Step 209: forward other flow processs of user to.
In conjunction with Benq station a concrete application scenarios, difference scheduling strategy is performed to user more below, consult shown in Fig. 3.
Step 300: base station obtains the scheduling identification preset of user.
Wherein, the scheduling identification preset comprises the difference scheduling mode of user preset and the combination of difference scheduling proportionality coefficient.
Step 310: base station judges whether the difference scheduling mode of user is priority scheduling.
If so, then step 320 is performed, otherwise, perform step 340.
Step 320: calculate the number of times that user preferentially jumps the queue within default difference dispatching cycle.
Base station, by presetting difference dispatching cycle and descending scheduling number of times, calculates the number of times of preferentially jumping the queue.
Step 330: be distributed in this difference dispatching cycle dispatch calculating the number of times of preferentially jumping the queue.
Step 340: calculate the number of times that user postpones to jump the queue within dispatching cycle.
