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 of carrying 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, the high speed descending sharing channel (HS-DSCH) of carrying customer service face data is shared channels of multiple users share.Compare with R4, shared channel is owing to be that multi-subscriber time shared is shared, when the user has demand data, just can take the HS-DSCH channel transmission data, 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 the channel of HSDPA carrying customer service is a shared channel, is inaccurate according to local resource only 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 allow 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, such as customer service being divided into the professional and non-GBR business of GBR.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

Below by specific embodiments and the drawings the present invention is described in further details.

Fig. 1 is the main flow chart of the method for the invention.Referring to Fig. 1, this method comprises:

Step 101, reception user's to be accepted service access request;

Step 102, determine the residual rate resource of sub-district HSDPA and described user's to be accepted path loss;

Step 103, described user's to be accepted path loss and preset path loss range compared, described residual rate resource is revised according to comparative result;

Step 104, judge whether corrected residual rate resource can satisfy described user's to be accepted rate requirement, 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 business (such as background business such as EMAIL, FTP downloads) of speed, therefore the present invention can also do respectively this two classes business and handle, promptly can be after step 101, further comprise before the step 102:

A1, judge the type of service that described user's to be accepted request inserts, if the access service of GBR, then need to consider HSDPA residual rate resource situation and user's to be accepted wireless environment, enter step 102; If be the access service of non-GBR,, therefore enter following step a2 because this kind business does not have the requirement of time delay and assurance bit rate;

Can the DPCH resource of a2, judgement sub-district satisfy this user's to be accepted requirement of following DPCH, if then admit this user; Otherwise, exclude this user.

Above-mentioned steps 102～104 mainly is the access at the GBR business of guaranteed speed, needs to consider HSDPA residual rate resource situation and user's to be accepted wireless environment.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 described definite sub-district HSDPA is:

B1, determine 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 described HS-DSCH is provided and described HS-DSCH deducts described GBR sum, and obtaining difference is described residual rate resource.

Generally speaking, the business of being asked all has priority, for situation with priority, this method is after the access request that receives the user, further determine the priority of this user institute requested service, and among the step B, determined residual rate resource is the residual rate resource of this priority correspondence.

The bit rate that described 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 described 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 herein, 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 of terminal _{Send_bits, k, i}, then the bit rate calculation formula that HS-DSCH provides on k user's i the priority is:

$R_{\mathrm{HS}-\mathrm{DSCH},k,i}=\frac{N_{\mathrm{send}\_\mathrm{bits},k,i}}{T}$ (bps) (1)

The total bit rate of all users that HS-DSCH provides on i priority is:

$R_{\mathrm{HS}-\mathrm{DSCH},i}=\underset{k=1}{\overset{K_i}{\mathrm{\Σ}}}{R}_{\mathrm{HS}-\mathrm{DSCH},k,i.}$ (bps) (2)

Wherein, K _iIt is total number of users of priority i correspondence in measuring period.

Definite method of the resource utilization of described 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 described all users that admitted are called and described total number of resources is as the resource utilization of the HS-DSCH that is asked.

Herein, 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, i}The 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, i}The 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:

$P_{\mathrm{HS}-\mathrm{DSCH},K,i}=\frac{N_{\mathrm{HS}-\mathrm{DSCH},K,i}}{N_{\mathrm{HS}-\mathrm{DSCH}}}---\left(3\right)$

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:

$P_{\mathrm{HS}-\mathrm{DSCH},i}=\underset{k=1}{\overset{K_i}{\mathrm{\Σ}}}{P}_{\mathrm{HS}-\mathrm{DSCH},k,i}---\left(4\right)$

Wherein, K _iIt is total number of users of priority i correspondence in measuring period.

In above-mentioned steps B1, also need to determine 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 herein.

After the GBR sum that bit rate, the HS-DSCH level of resources utilization and current all users that admitted that RNC obtains described HS-DSCH and provides have applied for, just can calculate the residual rate resource of determining current area HSDPA.

Suppose if user to be accepted request be that priority is the GBR business of i, the bit rate that HS-DSCH provides is R _{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 determine R according to following formula (5) _{Remain, i}:

$R_{\mathrm{remain},i}=\frac{R_{\mathrm{HS}-\mathrm{DSCH},i}}{P_{\mathrm{HS}-\mathrm{DSCH},i}}-{\mathrm{GBR}}_i---\left(5\right)$

In step 102, the concrete grammar of described definite user's to be accepted path loss is: network side at first carries out Radio Resource control (RRC) with described user to be accepted and is connected, carry out the measurement of basic Common Control Channel (PCCPCH) received signal code power (RSCP) by this user's subscriber equipment (UE), and measurement result is reported the RNC of network side; RNC deducts described measurement result with the reference transmit power of the PCCPCH that sets in advance, and the difference that obtains is the user's to be accepted that asked a path loss, promptly following formula (6)

L＝PTX _PCCPCH-PCCPCH?RSCP?(6)

Wherein, L is a user's to be accepted path loss, 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 described basic Common Control Channel received signal code power.

In step 103, need be according to described path loss L to R _{Remain, i}Revise, concrete modification method is as follows:

If L 〉=L _High, illustrate that described user's to be accepted wireless environment is poor, the Mean Speed that the speed that system provides for this user to be accepted will provide for the GBR business of i for priority less than system, need turn down R this moment _{Remain, i}, promptly the update the system bit rate that can provide for new user is:

$R_{\mathrm{remain},i}=(\frac{R_{\mathrm{HS}-\mathrm{DSCH},i}}{P_{\mathrm{HS}-\mathrm{DSCH},i}}-{\mathrm{GBR}}_i)\·(1-\mathrm{\η})---\left(7\right)$

If L≤L _Low, illustrate that described user's to be accepted wireless environment is relatively good, the Mean Speed that the speed that system provides for this user to be accepted will provide for the GBR business of i for priority greater than system, need heighten R this moment _{Remain, i}, promptly the update the system bit rate that can provide for new user is:

$R_{\mathrm{remain},i}=(\frac{R_{\mathrm{HS}-\mathrm{DSCH},i}}{P_{\mathrm{HS}-\mathrm{DSCH},i}}-{\mathrm{GBR}}_i)\·(1+\mathrm{\η})---\left(8\right)$

If L _Low＜L＜L _High, can think that speed that system provides for this user to be accepted and system are suitable for the Mean Speed that the GBR business of i provides for priority, this moment is not to described R _{Remain, i}Adjust, that is:

$R_{\mathrm{remain},i}=\frac{R_{\mathrm{HS}-\mathrm{DSCH},i}}{P_{\mathrm{HS}-\mathrm{DSCH},i}}-{\mathrm{GBR}}_i---\left(9\right)$

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 by simulation result and determine, obtains a more excellent numerical value.

According to above result of calculation, in step 104, can judge whether to admit described user to be accepted, the priority of supposing user applies to be accepted is that the professional GBR of i is R _{New, i}, R _{New, i}Be 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, and this user refuses in system.
