Description

A kind of acceptance controlling method in the CDMA mobile communication systems
Technical field
The present invention relates to mobile communication technology, relate to a kind of acceptance controlling method in code division multiple access (CDMA) mobile communication system or rather, the operation principle of the inventive method is applicable to all CDMA mobile communication systems.
Background technology
In the mobile communication system, call acceptance (or access) control (Call Admission Control, abbreviation CAC) problem to be solved is: when new calling or handover (HO) initiation request, radio network controller (RNC) is admitted according to certain criterion or is refused.After network was admitted new connection, its existing QoS of customer that connects (Quality of Service is called for short QoS) all should be met with the QoS of customer that newly is connected.Therefore, how not influencing under the prerequisite that connects (ongoing) QoS of customer, improve power system capacity to greatest extent, the subject matter that has just become Call Admission Control to solve.
The CAC problem is the problem that wired network and wireless network all must solve, because cdma system is a kind of interference-limited system, its special wireless environment makes the admittance problem become more complicated.
Before atm technology occurred, the admittance of cable network control was fairly simple, determined whether admitting new calling by network node according to the situation of occupying of outlet and buffer.After atm technology occurs,, all to consider therefore to make influence to other service-user and admit control to become one of major technique of atm technology to the admittance of any service-user because network will be born the transmission of multiple QoS service.
In arrowband-code division multiple access (N-CDMA) system, because network is mainly born the transmission of single-stage or two levels of traffic, professional admittance can adopt than be easier to implement based on the scheme of thresholding or adopt scheme based on sir measurement, but under the situation of multi-stage service, these schemes will face many difficulties: because different business has different QoS characteristics, if adopt scheme, a plurality of thresholdings will be set based on thresholding; If adopt scheme, a plurality of SIR standards will be set, thereby make real-time operation become very complicated based on sir measurement.
In the IS-95 cdma system, CAC mostly adopts the admittance scheme based on interference threshold point, often makes threshold value according to the most abominable situation, if all existing users' power all surpasses given thresholding in the current system, then new user will be rejected.This do not have the dynamic characteristic of taking into account system based on the admittance scheme of interference threshold point, and the capacity utilance of system is reduced, and causes the wasting of resources.Simultaneously it has only considered the interference that new user is suffered, and the access of not considering new user is to influence that system caused.
In principle, admittance in the static environment is exactly the capacity territory, but for a long time, the research of the capacity of system only is confined to static environment, dynamic environment when admitting Control Study should consider then that static environment is considered handover again also will be considered the operability of scheme.
The performance index of admitting control technology to relate to have call blocking rate, handover blocking rate etc.Theoretically, the key technology that CDMA relates to is to admitting control all influential, and wherein the most closely-related technology has power control, resource allocation, handover and topological structure.
Referring to Fig. 1, the wireless communication system of TD-SCDMA shown in figure principle structure (only providing the functional module relevant) with technical solution of the present invention.System is made up of a plurality of subscriber equipmenies (UE) 100, a plurality of base station (Node B) 110 and radio network controller (RNC) 120.Subscriber equipment 100 wherein can move in the different districts scope of system.Radio network controller 120 is cores of system, mainly comprises dynamic channel allocation 123, calls out access control 122 and parameter library 121 3 big funtion parts, and the with dashed lines frame goes out.
This system admits the process of control to be: subscriber equipment 100 (UE) sends call request to base station 110 (Node B), has measurement report relevant with access control and carrier/interface ratio parameter in call request; Node B admits control according to the call request of UE to the RNC request, and reports the measurement report relevant with admitting control; RNC is according to Node B carrier/interface ratio parameter and other parameters of system (the Internet resources operating position that UE measures etc.) about the measurement report of UE, UE, judge according to certain algorithm and access criterion, and last differentiation result, comprise and inserting or refusal, return to Node B, return to UE by Node B again.If what return is to admit successful message, then also comprise the adjustment information of transmitting power and the information that Radio Resource is redistributed, determine Initial Trans and the code channel of oneself for subscriber equipment 100 (UE).
In the radio network controller 120, dynamic channel allocation 123 receives the access solicitation message that send base stations 110, and determines the access slot of the higher time slot of priority as this user.Parameter library 121 contains three class parameters: channel model parameter, business model parameter and system model parameter.Parameter library 121 refreshes the parameter in the network according to the measurement report of subscriber equipment 100 and base station 110.Call out access control 122 according to the network parameter in the parameter library 121, in the selected time slot of dynamic channel allocation 123, carry out acceptance judging, and court verdict is returned to dynamic channel allocation 123.Dynamic channel allocation 123 sends the return messages that insert application according to court verdict to base station 110.
Summary of the invention

The technical scheme that realizes the object of the invention is such: a kind of acceptance controlling method in the CDMA mobile communication systems, comprise: the call request that new user's request of sending is admitted has the measurement report relevant with admitting control, new user's carrier/interface ratio parameter in described call request; Radio network controller comprises the admittance control of admitting or refusing according to described measurement report, new user's carrier/interface ratio parameter, it is characterized in that the admittance control of described admittance or refusal further comprises:
A. use new user not insert the up reception total power value and the downlink total power value of the actual measurement of preceding base station, calculating inserts up reception gross power in base station and the down initial total emission power after this new user and calculates new user's up Initial Trans;
B. with the power criterion the up reception gross power in base station after this new user of access who calculates, down initial total emission power and new user's up Initial Trans is judged, this power criterion comprises that whether the up reception gross power in described base station is less than given up received power threshold, whether described base station down initial transmissions gross power less than given down transmitting power threshold value, described new user's up Initial Trans whether smaller or equal to its uplink transmission power threshold value simultaneously more than or equal to its minimum emissive power;
C. when satisfying the requiring of above-mentioned power criterion, allow to admit, when not satisfying the requiring of above-mentioned power criterion, exclude.
In the described steps A, the up reception gross power in base station after the new user of described access is the up reception gross power of base station actual measurement before newly the user inserts and the base station ascending power increment Delta P after new user's access U_k+1Sum; Base station down initial transmissions gross power after the new user of described access is the downlink gross power of base station actual measurement before newly the user inserts and the descending power increment Delta P after new user's access D_i+1Sum, k+1, j+1 represent the new user that the uplink and downlink link inserts respectively, and u represents up link, and d represents down link, and P represents power; Up Initial Trans=Δ P of described new user U_k+1/ g U_k+1, g U_k+1The uplink pathloss factor of representing new user.

Embodiment
The present invention is a kind of CAC method rapidly and efficiently that provides for the cdma wireless communication system, be measured value according to reality calculate new user insert after the initial downlink total emission power and the up reception gross power of base station, and adopt based on the criterion of loading, new user is admitted control.
Below with reference to the application implementation example of the inventive method in TD-SCDMA system (structure in as Fig. 1), and further describe the present invention in conjunction with the accompanying drawings.
Fig. 2 has shown the main flow of call Cut-in control method among the present invention.Can be summarized in following steps:
Step 200, a new user sends call request;
Step 201, radio network controller are admitted control according to this call request at given time slot, obtain the carrier/interface ratio parameter of new user in the time slot to be accessed, and the correlation measure of network;
Step 202, adopt following method of measurement, promptly this new user of hypothesis can insert earlier, directly use the up reception total power value and the downlink total power value of the current actual measurement in base station, calculate and insert after this new user, the up reception gross power of base station, down initial total emission power and calculate new user's up Initial Trans;
Step 203 according to the power criterion, compares up reception gross power, down initial total emission power and the new user's of the base station that calculates up Initial Trans and established standards;
Step 204 when the up reception gross power of the base station that calculates, down initial total emission power and new user's up Initial Trans exceeds established standards, is then sent the judged result that excludes to the base station and by the base station to this new user;
Step 205 when the up reception gross power of the base station that calculates, down initial total emission power and new user's up Initial Trans does not exceed established standards, is then sent to this new user to the base station and by the base station and is allowed the judged result of admitting.
The core content of above-mentioned steps comprises method of measurement and according to result of calculation, judges whether the uplink and downlink gross power in the time slot to be accessed that calculates satisfies the power criterion: if satisfy, then allow to insert; Otherwise, refusal.
Admitting computational process with the uplink and downlink of user in the TD-SCDMA system below is example, and the thinking of finding the solution of method of measurement of the present invention is described.The up-admission process is described earlier.
If when newly calling arrives, k user arranged in the designated cell assigned timeslot, then new user's up carrier/interface ratio can be represented with new user's signal power, noise, interference (signal power that comprises interval interference, other users).If adopt smart antenna, joint-detection, new technology such as synchronous, added multiple access disturbs and handles the factor less than 1 in other users' signal power front.New user's up carrier/interface ratio can be expressed as:
( C I ) k + 1 u = Γ k + 1 u = P u _ k + 1 I u _ inter , k + 1 + α u · Σ i = 1 k P u _ i + P N = P u _ k + 1 P u _ inter , k + 1 - - - ( 1 )
Wherein, u represents up link, Γ K+1 uRepresent new user's up target carrier/interface ratio, C represents new user's carrier power, and I represents the interference power that new user is suffered.P U_i(i=1 ... k+1) be i user's receiving of base station signal power, I U_inter, k+1Be inter-cell uplink interference power, P NBe system's thermal noise power, P U_inter, k+1Be that new user inserts the suffered uplink interference power in back.α uIt is the processing factor that system disturbs uplink multi-address.
The core of method of measurement of the present invention is that it supposes that up, the downstream signal power of existing subscriber in the given time slot in given sub-district of moment of new user before and after inserting all remain unchanged, the actual measured value (up reception gross power, downlink gross power) that the suffered interference of so new user can utilize new user to insert preceding base station comes the new user of approximate calculation to insert the suffered interference value in back, thus up reception gross power and down initial total emission power after the user that must make new advances inserts.So new user's up Initial Trans can directly calculate with the measured value of base station and new user's carrier/interface ratio.If the carrier/interface ratio here is taken as desired value, the power that then calculates will satisfy new user's carrier/interface ratio condition automatically.Power control module is further adjusted this user's transmitting power in real time according to parameters such as carrier/interface ratios on the basis of these two values then.
Caused system uplink interference increment (power increment) Δ P after new user inserts U_k+1Can be expressed as the new subscriber signal power that the base station receives, that is:
Δ P U_k+1=new the user's of uplink interference Power x that new user is subjected to up target carrier/interface ratio (2)
Wherein, the uplink interference power that is subjected to of new user can calculate with the measured value of base station.Because when new user inserted, disturbed condition may be different with recent measurement, so the new subscriber signal power that the base station of trying to achieve in the top expression formula receives is an approximation.
The calculating of down transmitting power is identical with up thinking, just will consider the path loss factor in the computational process.If new the calling when arriving had j user in the designated cell assigned timeslot.
The descending power increment Delta P of system after new user inserts D_j+1Can be expressed as the signal power of base station: promptly to new user's emission
Δ P D-j+1=(the descending interference power that new user is subjected to * new user's descending target carrier/interface ratio)
/ new user's the path loss factor (3)
Wherein, the descending interference power that is subjected to of new user can obtain according to the actual measured value of base station before inserting new user.
In the formula (3), new user's the path loss factor is between 0～1.Item in formula (3) the right-hand member bracket is the desired power that receives of new user side, and this is exactly that the base station should be to new user's emitted power value with the effect of the path loss factor afterwards.
The formula of new user's descending target carrier/interface ratio institute foundation and up similar:
( C I ) j + 1 d = Γ j + 1 d = P d _ j + 1 I d _ inter , j + 1 + α d · Σ i = 1 j P d _ i + P N = P d _ j + 1 P d _ inter , j + 1 - - - ( 4 )
Every explanation and up similar in the formula (4): wherein, d represents down link, Γ J+1 uRepresent new user's descending target carrier/interface ratio, C represents new user's carrier power, and I represents the interference power that new user is suffered.P D_i(i=1 ... j+1) be the signal power of base station, I to i user's emission D_inter, j+1Be to the descending interference power in the minizone of inserting new user, P NBe system's thermal noise power, P D_inter, j+1Be that new user inserts the suffered descending interference power in back.α dIt is the processing factor that system disturbs downlink multi-access.
In the formula (1) (2), α u, a d, adopting smart antenna, joint-detection in mobile communication system, synchronously during new technologies such as one of (or all), its value is less than 1 even go to zero (when all using, handle the factor and go to zero); Do not adopt smart antenna, joint-detection in system, synchronously during new technologies such as one of (or all), its value is 1 when all not using (three, handle the factor and get 1).
Provided the power criterion of connection control method of the present invention below, this criterion should guarantee: after inserting new user: 1) base station is no more than given up received power threshold and down transmitting power threshold value separately to all users' up received power sum and down transmitting power sum; 2) new user's up Initial Trans can not surpass its transmitting power threshold value, and can not be less than its minimum emissive power; 3) suppose that existing subscriber's downlink gross power and up reception gross power insert moment new user and remain unchanged.Above-mentioned three all need be satisfied during judgement, that is:
Figure C0215807500122
p k + 1 , min ≤ ΔP u _ k + 1 g u _ k + 1 ≤ β 1 · p k + 1 , max - - - ( 7 )
In the formula, P U_total_old/ P D_total_oldUp reception gross power and downlink gross power when the new calling of expression arrives respectively; Δ P U_k+1/ Δ P D_k+1Represent uplink interference (power) increment and the descending power increment that cause by new calling respectively; P U_threshold/ P D_thresholdThe power threshold (load thresholding) of representing set up reception gross power/downlink gross power respectively; P K+1, min/ P K+1, maxRepresent minimum emissive power and maximum transmission power that new user allows; g U_k+1The uplink pathloss factor (in the TD-SCDMA system, user's the uplink pathloss factor and downlink path-loss factor approximately equal) of representing new user; β 1The redundancy factor of expression user emission power, β 1P K+1, maxThe uplink transmission power threshold value of representing new user.
