Description

During high speed downlink packet inserts to user's acceptance controlling method and system
Technical field
The present invention relates to the mobile communication technology field, relate in particular to high speed downlink packet and insert in (HSDPA) acceptance controlling method and system the user.
Background technology
In the R4 of mobile communication technology system, the channel that carries customer service is a dedicated channel, so user's admittance control is mainly adjudicated according to being local resource, if local resource is enough, then admits this user; Otherwise, refuse this user.
Along with the development of mobile communication technology,, introduced the HSDPA technology in order to improve traffic peak speed and power system capacity.The HSDPA system has adopted high order modulation (for example 16QAM), modulating-coding (AMC), mixing retransmit key technologies such as (HARQ), base station (Node B) fast dispatch automatically automatically, have greatly promoted the entire throughput of traffic peak speed and sub-district.
In the HSDPA system, carrying customer service face data in high speed DSCH Downlink Shared Channel (HS-DSCH) is the shared channel of multiple users share.Compare with R4; Shared channel when the user has demand data, just can take the HS-DSCH channel transmission data owing to be that multi-subscriber time shared is shared; When the user does not have demand data; HS-DSCH just can offer other user that demand data is arranged and use, so HSDPA can improve the level of resources utilization for sudden very strong Packet data service, increases power system capacity.Because it is shared channel that HSDPA carries the channel of customer service, be inaccurate only according to local resource so user's admittance is controlled.In principle, as long as following special physical channel (DPCH) satisfies condition, HSDPA just can admit abundant user.But if HSDPA admits too many user, it is less to cause the certain user to obtain the frequency ratio of HS-DSCH service, and quality of services for users (QoS) can not be guaranteed.Simultaneously,, will cause shared channel HS-DSCH utilance not high, cause waste of radio resources if the user that HSDPA admits very little.
At present, HSDPA mainly contains two kinds of acceptance controlling methods to the user:
Prior art one is a kind of acceptance method based on maximum number of user; Stipulate the maximum number of user that the HSDPA carrier wave can be admitted exactly; When new HSDPA user's requested service inserts; If the HSDPA user who has admitted in the sub-district does not reach the maximum number of user of setting, then can let this HSDPA user admission come in; Otherwise, refuse this new user and insert on the HSDPA carrier wave.
But the defective of this prior art is: calculate more roughly, this acceptance controlling method just roughly calculates the user capacity that HSDPA can carry, and does not consider user's application speed and qos requirement, does not consider user's wireless channel environment simultaneously.Therefore this acceptance controlling method can not guarantee to insert user's QoS.
Prior art two is a kind of acceptance controlling methods based on system resource utilization efficient, is exactly in one section measurement period, the efficiency of transmission of statistics sub-district HSDPA unit resource, and promptly in measurement period, statistics HS-DSCH unit resource is the bit number of transmission effectively; Pass through the surplus resources of statistics calculation plot HSDPA then; If the surplus resources of HSDPA is asked the service rate that inserts greater than new user, then admit this new user.Otherwise, exclude this new user.
The method of prior art two has been considered the actual transmissions efficient in the sub-district, has considered user's application speed and qos requirement simultaneously, and the professional and non-GBR of GBR is professional such as being divided into customer service.But; There is not to consider the new user's of admittance wireless channel environment in this acceptance controlling method; The accuracy of admission judgment is low, when new admittance user's wireless channel environment and sub-district HSDPA surplus resources are not inconsistent, can directly have influence on accessed user's the Qos and the stability of system.In addition, the method for calculation plot HSDPA residual rate resource is still continued to use the algorithm in the WCDMA system in the prior art two, and this algorithm is too complicated, causes the treatment effeciency of system low.

Embodiment
Through specific embodiment and accompanying drawing the present invention is explained further details below.
Fig. 1 is the main flow chart of the method for the invention.Referring to Fig. 1, this method comprises:
The service access request that step 101, reception wait to admit the user;
Step 102, the residual rate resource of confirming sub-district HSDPA and said path loss of waiting to admit the user;
Step 103, wait to admit user's path loss and preset path loss range to compare, said residual rate resource is revised according to comparative result with said;
Step 104, judge whether corrected residual rate resource can satisfy said rate requirement of waiting to admit the user, if satisfy then admit this user, otherwise, exclude this user.
Because the business that the user asks to insert can be divided into the total bandwidth request (GBR) professional (such as business such as Streaming Medias) of guaranteed speed and not guarantee the non-GBR professional (such as background business such as EMAIL, FTP downloads) of speed; Therefore the present invention can also do respectively these two types of business and handle, promptly can be after step 101, further comprise before the step 102:
A1, judge the type of service that the said request of waiting to admit the user inserts,, get into step 102 if the access service of GBR then need be considered HSDPA residual rate resource situation and the wireless environment of waiting to admit the user; If be the access service of non-GBR,, therefore get into following step a2 because this kind business does not have time delay and the requirement that guarantees bit rate;
Can the DPCH resource of a2, judgement sub-district satisfy the requirement of following DPCH that this waits to admit the user, if then admit this user; Otherwise, exclude this user.
Above-mentioned steps 102～104 mainly is to the professional access of the GBR of guaranteed speed, needs the wireless environment of considering HSDPA residual rate resource situation and waiting to admit the user.If the HSDPA surplus resources is enough, and this user's wireless environment is also relatively good, so just inserts this user.Otherwise, refuse this user's access.
In the above-mentioned steps 102, the concrete grammar of the residual rate resource of said definite sub-district HSDPA is:
B1, confirm bit rate, the resource utilization of HS-DSCH and the GBR sum that current all users that admitted have applied for that high speed descending sharing channel (HS-DSCH) provides;
The ratio of the resource utilization of B2, the bit rate that said HS-DSCH is provided and said HS-DSCH deducts said GBR sum, and obtaining difference is said residual rate resource.
Generally speaking; The business of being asked all has priority; For the situation with priority, this method is further confirmed the priority of this user institute requested service after the access request that receives the user; And among the step B, determined residual rate resource is the corresponding residual rate resource of this priority.
The bit rate that said HS-DSCH provides and the HS-DSCH level of resources utilization need base station (Node B) to measure calculating and report RNC.
Definite method of the bit rate that said HS-DSCH provides is specially: the MAC-hs entity statistics among the NodeB is in a measuring period; Priority corresponding to institute's requested service; Suppose to be priority i here; The total bit number of MAC-d protocol Data Unit (MAC-d) PDU that current all users that admitted send in the success of eating dishes without rice or wine, with this total bit number and this measuring period length the bit rate that provides as the HS-DSCH that is asked of ratio.
Concrete, in the measurement period T of MAC-hs entity statistics among the NodeB, under the priority i, each UE (distinguishing according to UEID) sends to and eats dishes without rice or wine and confirm has been N by the bit number of the correct MAC-dPDU that receives in terminal Send_bits, k, i, the bit rate calculation formula that then HS-DSCH provides on k user's i the priority is:
R HS - DSCH , k , i = N Send _ Bits , k , i T (bps) (1)
The total bit rate of all users that HS-DSCH provides on i priority is:
R HS - DSCH , i = Σ k = 1 K i R HS - DSCH , k , i . (bps) (2)
Wherein, K iIt is total number of users of priority i correspondence in measuring period.
Definite method of the resource utilization of said HS-DSCH is specially: add up in the measuring period; Priority corresponding to institute's requested service; The number of resources that current all users that admitted take when being called and total number of resources, the ratio of number of resources that takies when said all users that admitted are called and said total number of resources is as the resource utilization of the HS-DSCH that is asked.
Here; If the resource distribution mode of HSDPA is the time-division scheduling mode; Definite method of the HS-DSCH level of resources utilization is so: the MAC-hs entity among the NodeB was added up in the measuring period, under the priority of institute's requested service, and the timeslot number N that all UE take when being scheduled HS-DSCH, iThe timeslot number N total with HS-DSCH HS-DSCHRatio.If being sign indicating number, the resource distribution mode of HSDPA divides scheduling mode; Definite method of the HS-DSCH level of resources utilization is so: the MAC-hs entity among the NodeB was added up in the measuring period; Under the priority corresponding to institute's requested service, the basic code channel number BRU that all UE take when being scheduled HS-DSCH, iThe basic code channel number BRU total with HS-DSCH HS-DSCHRatio.Below with the resource distribution mode for the time-division scheduling mode is an example, the computational methods of the level of resources utilization are described.
In measurement period T of MAC-hs entity statistics among the NodeB, under the priority i, the timeslot number N that each UE takies when being scheduled HS-DSCH, i, then the HS-DSCH level of resources utilization is on k user's i the priority:
P HS - DSCH , K , i = N HS - DSCH , K , i N HS - DSCH - - - ( 3 )
Wherein, N HS-DSCHIt is the total timeslot number of HS-DSCH of system configuration.
The total level of resources utilization of all users that HS-DSCH provides on i priority:
P HS - DSCH , i = Σ k = 1 K i P HS - DSCH , k , i - - - ( 4 )
Wherein, K iIt is total number of users of priority i correspondence in measuring period.
In above-mentioned steps B1, also need confirm under priority i the GBR sum GBR that current all users that admitted have applied for iThis GBR iCan report RNC then by base station measurement, concrete method of measurement is a prior art, repeats no more here.
After the GBR sum that bit rate, the HS-DSCH level of resources utilization and current all users that admitted that RNC obtains said HS-DSCH and provides have applied for, just can calculate the residual rate resource of confirming current area HSDPA.
Suppose that the bit rate that HS-DSCH provides is R if user to be admitted asks is that priority is that the GBR of i is professional HS-DSCH, i, the HS-DSCH level of resources utilization is P HS-DSCH, i, the GBR sum that the user that current all priority of having admitted are i has applied for is GBR i, the residual rate resource of current area HSDPA is R Remain, i, then confirm R according to following formula (5) Remain, i:
R remain , i = R HS - DSCH , i P HS - DSCH , i - GBR i - - - ( 5 )
In step 102; Saidly confirm to wait to admit the concrete grammar of user's path loss to be: network side is waited to admit the user at first to carry out Radio Resource control (RRC) to be connected with said; Carry out the measurement of basic CCCH (PCCPCH) received signal code power (RSCP) by this user's subscriber equipment (UE), and give the RNC of network side reporting measuring result; RNC deducts said measurement result with the reference transmit power of the PCCPCH that is provided with in advance, and the difference that obtains is the path loss of being asked of waiting to admit the user, promptly following formula (6)
L＝PTX PCCPCH-PCCPCH?RSCP?(6)
Wherein, L is the path loss of waiting to admit the user, has embodied the quality of this user radio channel; PTX PCCPCHBe the reference transmit power of PCCPCH, be preset among the RNC; PCCPCH RSCP is the measurement result of said basic CCCH received signal code power.
In step 103, need be according to said path loss L to R Remain, iRevise, concrete modification method is following:
If L>=L High, to explain and saidly wait to admit user's wireless environment poor, the speed that system provides for this user to be admitted will be that priority is the Mean Speed that the GBR business of i provides less than system, need turn down R this moment Remain, i, promptly update the system can be for the bit rate that new user provides:
R remain , i = ( R HS - DSCH , i P HS - DSCH , i - GBR i ) · ( 1 - η ) - - - ( 7 )
If L≤L Low, to explain and saidly wait to admit user's wireless environment relatively good, the speed that system provides for this user to be admitted will be that priority is the Mean Speed that the GBR business of i provides greater than system, need heighten R this moment Remain, i, promptly update the system can be for the bit rate that new user provides:
R remain , i = ( R HS - DSCH , i P HS - DSCH , i - GBR i ) · ( 1 + η ) - - - ( 8 )
If L Low＜L＜L High, can think that system is that the speed that provides of this user to be admitted and system are that priority is that the Mean Speed that provides of the GBR business of i is suitable, this moment is not to said R Remain, iAdjust, that is:
R remain , i = R HS - DSCH , i P HS - DSCH , i - GBR i - - - ( 9 )
In formula (7), (8), (9), L LowAnd L HighBe respectively the high threshold and the low threshold of preset path loss; η is the rate correction factor, and this rate correction factor can be soundd out through simulation result and confirm, obtains a more excellent numerical value.
According to above result of calculation, in step 104, can judge whether to admit user said to be admitted, the priority of supposing to wait to admit user applies is that the professional GBR of i is R New, i, R New, iBe the rate requirement of this user's requested service, be specially:
If R Remailn, i>=R New, i, illustrative system has enough resources to admit this user, and system admits this user.
If R Remain, i＜R New, i, illustrative system does not have this user of enough resource and admissions, this user of refusal of system.
