Description
Technical field
The present invention relates to a kind of downlink call acceptance controlling method of radio honeycomb communication system, relate in particular to the downlink call acceptance controlling method of the WCDMA mobile communication system of supporting that the high-speed down data bag inserts at non-real-time service.
Background technology
High speed downlink packet insert (HSDPA) be 3GPP in the R5 agreement on satisfying/the asymmetric demand of downstream data traffic and a kind of new technology of proposing, it has solved the contradiction between system's covering and the capacity well, promote power system capacity greatly, satisfied user's high speed business demand.HSDPA has adopted Adaptive Modulation and Coding (AMC) and has mixed and repeat (HARQ) two kinds of key technologies automatically, can bring up to 10M to downstream data traffic speed under the situation that does not change the WCDMA network configuration of having built.The HSDPA technology is by fast physical layer retransmission and transmission merging and the rapid link self adaptation next throughput that can improve grouped data of use by Node B (base station) control.The transmission channel of the user data of carrying HSDPA operation is called high-speed downlink shared channel (HS-DSCH).Provide the fundamental block diagram of HSDPA as Fig. 1.Node B101 carries out channel quality estimation according to power control, ACK/NACK ratio, Quality of Service and the specific field feedback of HSDPA that each is carried on the user 102 on the HSDPA, and, dispatch rapid adjustment with link circuit self-adapting according to the dispatching algorithm and the User Priority algorithm of current employing.
In the 3GPP standard, four kinds of types of service have been defined: conversation type (Conversational), stream type (Streaming), type of interaction (Interactive class), backstage type (Background class).The main distinction between these types of service is professional sensitivity to time delay.The business of conversation type is very responsive to time delay, and the backstage type is then least responsive to time delay.The business of conversation type and stream type belongs to real time business; Type of interaction and backstage type belong to non-real-time service.
Because conversation type and stream type have strict delay requirement, particularly conversation type, need constant bit speed, so the business of conversation type and stream type is fit to be carried by dedicated channel.Type of interaction and backstage type are not high to delay requirement, but need to keep the integrality of data, can pass through common signal channel, dedicated channel or shared channel carrying.The settling time of common signal channel is short, is fit to the little not frequent grouped data of transmission, is mainly used in to send short IP grouping during TCP connects foundation; The advantage of dedicated channel is support to use fast power control and soft handover, but the time of setting up is long and take the sign indicating number resource of down link; Shared channel is used for the transmitting burst grouped data, by the time-division and (or) the sign indicating number mode of dividing is in the shared among users resource of non-real-time service, thereby the sign indicating number resource of saving down link.
At broadband CDMA system, use the notion of soft capacity: the generation of each new calling has increased all and has had the interference level of calling, influences its communication quality.Therefore the access of controlling user-to-network by rights is a very important problem, and this mode is called Call Admission Control (CAC:Call Admission Control).According to the 3GPP standard, CAC is positioned at control RNC (CRNC) (RNC: radio network controller).Before accepting a new RAB, admit control can assess the increase that this carries load in the wireless network that is caused.Have only the admittance of up link and down link to control in the time of all can receiving this radio bearer, the carrying that the ability receivability is asked, otherwise just refuse this carrying request.Service quality (Quality of Service) according to service request is carried out Call Admission Control, when the COS of business is ' trying one's best ' (Best Effort), can not carry out Call Admission Control.
Existing Call Admission Control is that the business that is carried on the dedicated channel is carried out acceptance judging based on the strategy of descending power and uplink interference, and the professional reserved resource of asking is to guarantee professional service quality (QoS).But in high speed descending grouping access system, when using HSDPA technology carrying stream type professional, since the downlink resource of HSDPA be by the time-division or (with) a sign indicating number mode of dividing is that a plurality of users share, and therefore uses the method for existing Call Admission Control can not guarantee the service quality of requested service.

Embodiment
Basic thought of the present invention is based on the type of service of call request, carries out different call acceptance strategies and selects suitable channel type to come bearer service according to the operating position of resource.
The business of conversation type is a real time business.The business of conversation type must keep the time relationship between information entity in the Business Stream in transmission course, have harshly, and therefore low delay requirement needs to distribute special-purpose channel resource carry the conversation type business.
The stream type business is a real time business, and the bit rate and the time delay of transfer of data had certain requirement, and according to the design of HSDPA, the stream type business can be carried on HS-DSCH or the dedicated channel.
Non-real-time service is the COS that belongs to ' trying one's best ' (Best Effort).If use dedicated channel to carry non-real-time service, then need to carry out and admit control, and according to maximum bit rate assigned code resource, this can cause the waste of yard resource; Also can utilize variable spreading factor (SF) to adjust data rate in transmission course according to the situation of business transmission by the discount of maximum bit rate being admitted control and Resources allocation.If use high-speed downlink shared channel to carry non-real-time service, because non-real-time service does not need to guarantee professional ' guaranteed bit rate (bit rate guarantee) ' and ' Transfer delay (moving time-delay) ', so can not need acceptance judging just directly to admit.But consider the characteristics (big delay variation triggers the startup slowly of TCP easily) of TCP transmission, slowly start the decline that causes systematic function for fear of too much triggering TCP, therefore in the present invention, the access request of non-real-time service carried out admits control, to non-real-time service according to priority setting ' minimum transfer bit rate '.
The present invention considers whether the stream type or the non real-time type service of request are carried on the HS-DSCH by the transmitted bit speed that is carried on number of users on the HS-DSCH and current HS-DSCH and provides.When HS-DSCH can't carry this non-real-time service request, consider to use common signal channel to carry this request, because short IP transmission packets during the suitable TCP connection of the common signal channel foundation.When using common signal channel carrying non-real-time service, in transmission course, when volume of transmitted data surpasses certain thresholding, carry out the switching of channel, professional carrying is transferred on HS-DSCH or the dedicated channel from common signal channel; When HS-DSCH can't carry this non-real-time service request and common signal channel and also can't carry this non-real-time service request, consider to use dedicated channel to carry this service request.If when dedicated channel can not provide the required resource of service request maximum bit rate, then need the maximum bit rate of service request is carried out discount, admit control and resource allocation according to the bit rate after the discount.In transmission course, can utilize variable spreading factor (SF) to adjust the message transmission rate of dedicated channel according to the situation of business transmission.
With reference to figure 5, be the flow chart of the inventive method;

Judge whether this business can be based upon on the dedicated channel.At first carry out based on the admittance of power or throughput strategy and control according to the maximum bit rate of this service request.If allow to insert, then carry this service request according to maximum bit rate assigned with dedicated channel resource.If do not allow, then the maximum bit rate to service request carries out discount, the bit rate after the discount is carried out based on the admittance of power or throughput strategy controlled.If allow to insert, then carry this service request according to the bit rate assigned with dedicated channel resource after the discount, otherwise the access of refusal service request.The admittance control procedure of calling out the request of access finishes.
Fig. 1 has provided the fundamental block diagram of HSDPA.Node B101 carries out channel quality estimation according to each HSDPA user's 102 power control, ACK/NACK ratio, quality of service and the specific field feedback of HSDPA, and dispatches rapid adjustment with link circuit self-adapting according to the dispatching algorithm of current employing and User Priority algorithm.In order to realize the functional characteristic of HSDPA, in physical layer specification, introduced three new channels:
HS-DSCH: the carries downlink user data, when adopting the 16QAM modulation, its peak rate can reach 10Mbit/s.
HS-SCCH: the physical layer control signaling that is used for decoding on the carrying HS-DSCH.If take place to retransmit or the erroneous packet data, this channel also comprises possible physical layer data combination.
HS-DPCCH: the carrying uplink control signaling, i.e. ARQ affirmation and downlink quality feedback letter open.
At first UE102 monitors the HS-SCCH channel, determines the code word that despreading HS-DSCH is required with a time slot, utilizes the specific mask of UE102 to judge whether the data of reception are oneself.If then utilize the data on the message pick-up HS-DSCH on the HS-SCCH.Produce CRC (CRC) check results after ACK/NACK information reflects grouped data decoding and merging after the UE102 reception data, and the quality condition of current down link is indicated in downlink quality indication (CQI).
Fig. 2 has provided the basic procedure of public-measurement between RNC and Node B.
In step 201, RNC sends the public-measurement control request to Node B, and the relevant parameter of allocating and measuring.
In step 202, when the condition of measurement report satisfies (cycle or incident), Node B report measurement result to RNC.
In step 203, RNC preserves the measurement result of Node B report.
Fig. 3 has provided the fundamental block diagram of service wireless network controller (Service Radio Network Control:SRNC) Call Admission Control.When SRNC 307 receive that CN sends ' during the message of RAB assignment request ' 301, SRNC 307 gives RRM entity 306 message and admits control.In module 304, RRM (Radio ResourceManagement:RRM) entity 306 is carried out the corresponding call admission control scheme according to the type of service and the service quality of request, will consider the loading condition that the sub-district is current simultaneously and estimate that the foundation of carrying causes the increase of wireless network load.According to the judgement of module 304, if new request allows to insert, then module 305 is new traffic assignments resource.SRNC transmission ' RAB is assigned response ' message 302 is given CN, and the result of appointment is asked in report.
Shown in Figure 4 is concrete admittance control procedure.At first step 401 is when SRNC receives CN ' RAB assignment request ', and it is congested that step 402 judges whether the sub-district present load is in.If the sub-district is in congested, the then access of the business that step 417 refusal is new, the admittance process finishes; Otherwise step 403CAC carries out the corresponding judgement that inserts according to the qos parameter in the message according to the type of service of request.
When the type of service of request when being the real time business of conversation type, the increase that step 409 item is come estimating down-ward link and uplink load according to the requirement of the maximum bit rate of service request.Step 410, the increase of having only increase when down link can't cause that the total transmitting power of down link surpasses certain threshold value and uplink load also can not cause when the interference of up link surpasses certain threshold value, CAC allows this service request to insert, and step 414 is come the business of assigned with dedicated channel resource bearing request according to the maximum bit rate of request, and step 417 admits control procedure to finish afterwards; If the condition of step 410 does not satisfy, and the type of service of step 411 judgement request, if session service, step 416 refusal inserts, step 417 is admitted the control procedure end.
When the type of service of step 403 request was stream type business or non-real-time service, at first step 404 judged whether the business of request can be based upon on the HS-DSCH.
If stream type and non real-time type service can be divided into I subservice, each subservice number is respectively 0,1 ..., I-1, corresponding different priority.If PRI
