Description
Technical field
The present invention relates to wireless communication field, particularly the method for base station and definite service traffics.
Background technology
Introducing high-speed downstream bag data access (HSDPA, High Speed Downlink Packet DataAccess) after the technology, the shortage of the uplink capacity that causes for the growth that reduces because of the down link load, further improve the up average throughput and the capacity of single user and system, and shortening postpones, thereby carry out multimedia service and bag transfer of data better, introduce high speed uplink bag data again and inserted (HSUPA, High Speed Uplink Packet Data Access) technology.The HSUPA technology is that 3GPP is organized in a kind of new technology that improves up transfer rate of introducing in the R6 agreement, it adopts up fast dispatch, the physical layer of base station (NodeB) to mix and retransmits (HARQ, HybridAutomatic Repeat reQuest,), soft handover, 2ms Transmission Time Interval (TTI, Transport Time Interval) lacks the frame transmission technology, can support peak-peak speed 5.76Mbps in theory.

Embodiment
The embodiment of the invention proposes a kind of method of definite service traffics, and referring to Fig. 2, Fig. 2 determines to comprise the method flow diagram of service traffics for the embodiment of the invention:
Step 201: in the predefined time cycle,, calculate the user's who receives in the described time cycle total amount of data according to the E-TFCI that strengthens transmission in the dedicated channel Dedicated Physical Control Channel (E-DPCCH).
Step 202: whether judge described total amount of data less than predefined total amount threshold value, if less than, the business of then judging described user is the low discharge business.
As described in the background art, the HSUPA system is in E-DPDCH transmission data, and transmission bearer demodulation E-DPDCH's follows signaling in E-DPCCH; Wherein E-DPCCH is used for representing data quantity transmitted among the interior E-DPDCH of this TTI time period at each TTI transmission E-TFCI.Utilize this characteristics, the concrete mode of the user's who receives in cycle computing time according to E-TFCI in the above-mentioned steps 201 total amount of data can be the summation of calculating the indicated transmitted data amount of the E-TFCI among all TTI in the described time cycle.
In the said method, calculate the current data quantity transmitted of user, current data quantity transmitted is during less than predefined total amount threshold value, and the business of then judging this user is the low discharge business.
In the prior art, the user can send schedule information (SI to NodeB, SchedulingInformation), the enhancing dedicated channel that comprises among SI buffering situation total amount index (TEBS Index, Total E-DCH Buffer Status Index) is used for indicating the data volume of this user's buffer memory dispatching services.
Utilize above-mentioned prior art, the embodiment of the invention can also adopt more strict judgement mode, that is: judge that not only whether the current data quantity transmitted of user is less than the total amount threshold value, also need further judge the user will data quantity transmitted whether less than certain thresholding, when two conditions satisfied simultaneously, the business of just judging this user was the low discharge business.
Concrete mode can for: in the above-mentioned steps 202, judge total amount of data, may further include less than after the predefined total amount threshold value:
In the described predefined time cycle, receive the schedule information SI that the user sends, whether judge TEBS Index among the described SI less than predefined TEBS threshold value, if less than, then continuing to carry out the business of judging described user is the step of low discharge business.
When NodeB identifies the low discharge business, can in scheduling process, when priority queueing, the low discharge business be come the foremost, when interface-free resources occurring, give the low discharge business the interface-free resources priority allocation of described free time.
Below lift specific embodiment, introduce the specific implementation of identification low discharge business and priority scheduling low discharge business in detail.
Step 1: to the judgement of transmitted data amount:
For example setting in advance the time cycle is 500ms, and the initial value of setting mark 1 (Flag1) is true (True), represents that current data quantity transmitted is little.When one-period began, No deB enabling counting device calculated the summation of the indicated data volume of the E-TFCI in the E-DPCCH channel in this cycle.The summation of calculating when counter is during greater than predefined total amount threshold value (the total amount threshold value is set to 4kbit in the present embodiment), and the value of Flag1 is changed to vacation (False), represents that current data quantity transmitted is big.During each end cycle, above-mentioned counter is reset to 0, restart the counting of following one-period.
Step 2: to the judgement of pre-transmitted data amount:
The initial value that preestablishes mark 2 (Flag2) is true (True), and expression is will data quantity transmitted little.Simultaneously in the above-mentioned time cycle that sets in advance, receive the SI that the user sends, judge whether (the Index threshold value is set to 23 in the present embodiment greater than predefined Index threshold value for TEBS Index among this SI, corresponding value is 3884byte＜TEBS＜=5160byte), if, then the value with Flag2 is changed to False, and expression is will data quantity transmitted big.
Step 3: to the judgement of low discharge business:
When one-period finishes, put when being True when the value of above-mentioned Flag1 and Flag2, the business of judging this user is the low discharge business.
Be understood that easily, Flag1 in the above-mentioned steps and Flag2 are only for judging convenient the setting, other embodiments of the invention also can adopt the represented implication of the different values of other marks, other mark initial values and mark, as long as can make a mark to judged result.
In case a user's business is judged as the low discharge business, when scheduling, pay the utmost attention to this class user, satisfy this class user's rate request as far as possible, promptly when priority queueing, this class user is placed on the foremost, in case interface-free resources is arranged, just distributes to this class user as far as possible.
