Description
Technical field
The present invention relates to mobile communication technology, relate to a kind of resource integrated method or rather, be suitable in time division duplex/CDMA mobile communication systems (TDD/CDMA), using.
Background technology
The resource consolidation technology is to improve an effective technology of resource utilization ratio.Used this notion of resource consolidation in wired network for a long time, " defragmentation " function of generally supporting in for example present computer is exactly that a concrete exploration is used.
In radio communication, because resource lacks relatively on the air interface, improve resource utilization is the target that system design is pursued always.In the first generation and second generation mobile communication system, because professional unicity and be subjected to the limitation of wireless communication technology at that time, a user occupies a channel just is enough to the voice-over business, do not bring into play the condition of resource consolidation advantage, therefore just do not occur yet concrete, can be applied to the resource integrated method in the wireless communication system.In 3-G (Generation Three mobile communication system), the business of being supported is tending towards variation, and resource quantity and quality that the business that different QoS requires takies also have nothing in common with each other, and portable terminal has also possessed the tenability of many code channels and multi-slot gradually simultaneously.On this basis, resource consolidation technology just really possesses the condition of the practical application of entering in wireless domain.
Resource consolidation technology in broadband-code division multiple access (W-CDMA) system mainly is applied as " sign indicating number defragmentation " technology.Because the limited amount of the variable orthogonal code of spreading factor, and a user may use a plurality of orthogonal codes, must consider that therefore the sign indicating number reasonable resources uses a problem, to guarantee to satisfy user's requirement.When the sign indicating number resource allocation, the situation of channel code table fragment may appear, just do not carry out a yard resource allocation according to compact principle, the sign indicating number resource allocation is unreasonable; After perhaps passing through long-play, because the randomness of sign indicating number resource occupation and release, the situation of fragment can appear also, the sign indicating number resource occupation that has promptly distributed empty rate resource, reduced a yard resource utilization.
The concrete enforcement of sign indicating number resource consolidation technology shows as statistics sign indicating number efficiency of resource, in case the sign indicating number level of resources utilization is just implemented the work of channel code table defragmentation when being lower than certain threshold value, promptly carries out reshuffling of yard resource.Because available spreading code is up to 256 in the W-CDMA system, for consideration to the frequent degree of the complexity of algorithm and Signalling exchange, thereby in actual engineering, often more energy is concentrated on that sign indicating number distributes rather than " sign indicating number defragmentation " on.
And for the TDD/CDMA system, characteristics based on the TDD system, available spreading code negligible amounts (as 16) in each time slot, owing to reduced the complexity of algorithm, thereby can select more optimal method to carry out the distribution of spread spectrum code resources, combination and defragmentation, therefore the problem of " sign indicating number fragment " can be well solved; The TD-SCDMA system supports the combination of resources mode between multi-slot simultaneously, can be according to the technical characterstic of self system, carry out the scheduling of resource flexibly in conjunction with the quality of service requirement (QoS:Quality of Service) of user applies business and the tenability of terminal; Be aided with the support of dynamic channel allocation (DCA) technology again, make the resource consolidation technology can obtain using more widely, thereby improve the resource utilization of system in the TDD/CDMA system.
Comprehensively used time-division and sign indicating number branch technology based on the mobile communication system of time division duplex code division multiplexing, on the high efficiency that the flexibility and the resource of resource allocation are used, significant advantage has been arranged.But because the employing of time division technique makes the available resources of system be dispersed in each time slot, for the more business of ask for something resource quantity, the interior surplus resources of time slot may not satisfy its requirement; For to the realization that is easy to power control and switching controls etc. and the consideration of simplification control operation, wish to be that a user distributes the resource in the same time slot as far as possible, can integrate surplus resources in the system in the case, the surplus resources that makes part be dispersed in each time slot originally concentrates on a certain time slot as far as possible, so that distribute to the user that will insert.
Summary of the invention
The purpose of this invention is to provide the resource integrated method of a kind of TDD/CDMA of being applicable to system, can rapidly and efficiently finish resource consolidation.
The technical scheme that realizes the object of the invention is such: the resource integrated method of a kind of TDD/CDMA of being applicable to system is characterized in that comprising:
A. system monitoring is to the trigger condition that satisfies resource consolidation;
B. system arrives other time slot according to the time slot priority orders with the customer business transition in the time slot, discharges customer service in the shared basic RU resource of this time slot;
C. the basic RU resource of this time slot that will vacate is distributed to the new customer service many to basic RU resource requirement.
Among the described step B with the customer business transition in the time slot to other time slot, be by the time slot priority orders from the highest time slot of priority, with the customer business transition in the high priority time slot in the low priority time slot.Time slot priority wherein is to arrange by the principle of time slot load balancing, and the priority of the time slot that remaining basic RU resource is maximum is the highest.
Among the described step B with the customer business transition in the time slot to other time slot, be by the time slot priority orders from the highest time slot of priority, with the customer business transition in the low priority time slot in the high priority time slot.Priority wherein is to concentrate the principle of distributing to arrange relatively by the time slot resource, to session service, the priority of up access is arranged to uplink and downlink timeslot transfer point forward in turn from first time slot, and the priority of descending access is arranged in turn from uplink and downlink timeslot transfer point to tail time slot forward; To stream class service, the priority of up access is oppositely arranged in turn from the uplink and downlink timeslot transfer point to first time slot, and the priority of descending access is oppositely arranged in turn from the tail time slot to the uplink and downlink timeslot transfer point.
The resource integrated method that is applicable to time division duplex/code division multiple access system of the present invention, made full use of the flexibility of TDD system resource allocation, certain customers in the time slot can be transferred to other time slot, to concentrate the surplus resources in a plurality of time slots, give the new user more with these resource allocations again to resource requirement.This method combines with admission control algorithm, can accomplish that transferring user is minimum, it is less to integrate time-delay, therefore can efficiently finish resource consolidation fast in time division duplex/code division multiple access system.

Embodiment
Fig. 1 illustrates the resource consolidation process of utilizing the inventive method to realize.The resource consolidation that the present invention is alleged briefly is moved to other time slot with the certain customers in the time slot exactly, allows this time slot vacate enough resources so that offer the user more to resource requirement to be accessed.Show the basic resource unit (RU) of just carrying customer service with the oblique line frame table among the figure, by the business in the time slot 1,2 is transferred in the target time slot 3, thereby discharge this business in the shared basic RU resource of former time slot 1,2.Through after the resource consolidation, the time slot 1,2 that system vacates complete (perhaps complete as far as possible) is for the access of bigger business.Before the resource consolidation, business takies the situation of time slot 1,2,3 basic resource unit (RU) shown in Figure 1A, through the time slot 3 after the resource consolidation, business take the situation of basic RU and the situation of the complete time slot 1,2 vacated as shown in Figure 1B.
The time interval resource of TDD/CDMA system in a carrier wave should comprise the implication aspect two of code channel and the power, moves certain customers out to other time slot from a time slot, and remaining code channel and power resource all can increase in this time slot.Resource consolidation flow process of the present invention can be considered code channel resource separately for the judgement of time interval resource, also can take all factors into consideration code channel resource and power resource.Under the latter event, need finish by certain admission control algorithm for the judgement of power resource.
The triggering of system resource integrative action has three kinds of situations: system cycle ground detects, and when testing result shows that ratio that the number of resources of scattered distribution in the system accounts for the total resources number reaches certain threshold value, promptly triggers integrative action; When having code channel to discharge, detect, when testing result shows that ratio that the number of resources of scattered distribution in the system accounts for the total resources number reaches certain threshold value, promptly trigger integrative action; Only when arriving, the professional application of real time high-speed rate implements resource integration.The benefit of preceding two kinds of ways is always to vacate a certain proportion of monoblock resource, can reduce real time high-speed rate service access time delay; The benefit of last a kind of way is to account for the total traffic ratio hour at high-rate service, and the integrative action of system can be very not frequent, thereby expense is few.
Further specify resource consolidation technology of the present invention below in conjunction with two specific embodiments and accompanying drawing thereof.
Referring to Fig. 2, be user's process that application resource is integrated in access procedure.Among this first embodiment, vacate the high time slot of priority, offer the user more to be accessed resource requirement through the resource consolidation process.USERn is new User ID, and USERa is a User ID to be transferred.Each time slot can be according to the average criterion design time slot priority queueing algorithm of load, and promptly according to the priority query that how much forms of surplus resources in the time slot, the priority of the time slot that surplus resources is maximum in this formation is the highest.
Step 203, choosing one in time slot i takies resource quantity and is less than the user of new customer requirements resource quantity as user USERa to be transferred, can avoid like this causing integrating failure because of the more user USERa of transferring resource requirement, if there is inhomogeneous user can both satisfy above-mentioned requirements in the time slot i, then selecting wherein to take the maximum user of resource is USERa, does like this and can reduce the number of users that shifts.
Step 204 is made acceptance judging to adding USERa in other time slot beyond the time slot i, goes (utilizing the acceptance judging algorithm to carry out) to judge whether successfully to transfer to USERa in some time slots in these time slots.
Step 205,206, if a certain time slot j of USERa outside time slot i passes through acceptance judging, do not carry out at once USERa is transferred to the operation of going among this time slot j this moment, but the state of recording integrating operation only, and then execution in step 207, the state of recording integrating operation comprises that target time slot j, time slot i that the ID, the USERa that write downs USERa shifts have lacked among the disturbance regime behind the USERa, the target time slot j many disturbance regimes behind the USERa etc., notices that later various judgements all will carry out under the state of supposing after USERa transfers to target time slot j.
Step 213 if in step 205, is transferred to the acceptance judging that goes in the time slot with USERa and is not passed through except that time slot i, explanation can not successfully be transferred to other time slot to USERa, and the resource consolidation failure provides the information of integrating failure.
If through above-mentioned steps, fail in time slot i, to choose a user USERa to be transferred always, then select time priority time slot as the time slot of admitting new user, and repeated execution of steps 203 to 214, until the time slot that finds can therefrom choose user to be transferred.This repetitive process is carried out toward low from high by time slot priority.
The user who adjusts when the integration flow process among Fig. 2 embodiment can accomplish to integrate is few as far as possible, owing to integrate the channel adjustment operation that causes, reduces signaling consumption to reduce.Before the real operation of carrying out transferring user, this flow process has been carried out the pre-acceptance judging operation that target time slot is treated transferring user, can successfully carry out to guarantee to shift, and does not influence to connect the user's communications quality; This flow process also has the acceptance judging that under the situation that the user removed new user is inserted this time slot from time slot in hypothesis, have only and after new user is by acceptance judging, just carry out the transferring user operation, so not only avoided invalid transfer operation, processing delay is greatly reduced.Do the operation of acceptance judging under this situation that moves into or remove certain customers in hypothesis, need the support (have multiple admission control algorithm in the prior art, can select to use) of admission control algorithm.
One of advantage of TDD/CDMA system is to adopt time division duplex (TDD) mode, can satisfy the needs of asymmetric traffic flexibly.But the problem of bringing simultaneously is: because all system resource is assigned in the different time slots, cause the resource extent in the time slot limited, for the portable terminal that does not possess the multi-slot control ability, bring certain difficulty can for the access of some real time high-speed rate business.And resource integrated method provided by the invention just can solve this difficulty.Therefore under the principle that guarantees each time-slot load equilibrium, carry out in the resource distributor system, can use above-mentioned resource consolidation scheme.
Second embodiment is the resource consolidation process of concentrating relatively under the distribution condition in resource, carrying out in non-access process.Among this second embodiment, fill up the high time slot of priority earlier, vacate other time slot through the resource consolidation process.Present embodiment relates to a concrete time slot sort method, is a kind of method that priority orders artificially is set.
Referring to Fig. 3, in the middle of the TDD-CDMA system, operator may have a plurality of carrier frequency, one frame of each carrier frequency has a plurality of time slots, in the middle of each time slot, is divided into some code channels with spreading code, at this, define the TDD-CDMA system channel that is combined as of " carrier frequency+time slot+code channel ".Further, it is a basic Resource Unit (RU) that the definition spreading code adopts the code channel of SF=16, and then the maximum RU number that allows to exist according to related standards in time slot promptly is defined as the resource sum of this time slot.Can adopt different resource distribution modes respectively to different business, business of the same race is focused in the identical time slot as far as possible, use for the user thereby vacate more complete time slot as far as possible.
The subframe of supposing a TDD/CDMA system comprises K conventional time slot, is labeled as TS respectively
0-TS
K, TS wherein
0With TS
KBetween a transfer point that is up to descending time slot is arranged, this time slot position of conversion point can be set according to service needed.Suppose in this system, on/the descending time slot transfer point is set in TS
NAnd TS
N+1Between, be about to TS
1-TS
NAnd TS
N+1-TS
KBe used separately as the uplink and downlink time slot.
The artificial time slot sort method that is provided with as shown in Figure 3.When the access of calling request is arranged, at first judge type of service (step 301), for some kind business, such as session service, the prioritization of time slot is: up from TS
1To TS
NInsert in turn, as the TS among the figure
1＞TS
2...＞TS
N(step 302); Descending from TS
N+1To TS
KInsert TS in turn
N+1＞TS
N+2...＞TS
K(step 302).For other class business, as stream class service, the prioritization of time slot is: up from TS
NTo TS
1Oppositely insert TS in turn
N＞TS
N-1...＞TS
1(step 303); Descending from TS
KTo TS
N+1Oppositely insert TS in turn
K＞TS
K-1...＞TS
N+1(step 303).
Under above-mentioned prioritization principle, carry out resource allocation and resource consolidation, professional resource requirement can be separated in each time slot substantially by type of service, can guarantee the access success rate of high-speed data again, reduce access delay.During concrete enforcement, above-mentioned prioritization principle can change neatly, for example allows the priority of conversation class and stream class service insert to sort exchange etc.
At this moment, the trigger condition of resource consolidation can adopt the mode of Event triggered or cycle polling, when adopting Event triggered, when finishing resources such as discharging code channel, power as the telex network in the high time slot of priority, trigger resource consolidation, or when the ratio that system monitoring accounts for the total resources number to the number of resources of scattered distribution reaches certain threshold value, trigger resource consolidation; When adopting the cycle polling mode,, trigger resource consolidation in case find in the high time slot of priority the vacant code road is arranged.Under above-mentioned two kinds of resource consolidation triggering modes, implement resource integration and exactly the customer service of disperseing in other low priority time slot is incorporated into respectively in the high priority time slot, preferentially fill up the high time slot of priority, vacate complete time slot with as much as possible, so just needn't do integration temporarily in the professional moment that arrives of real time high-speed rate.
Referring to Fig. 4, the implementation process of concentrating the resource consolidation under the distribution condition in resource relatively is described.It also is a kind of flow process that can in non-access process, implement resource integration.
In above-mentioned steps 405 or step 407, if not choosing one in this low priority time slot, to take available RU number among RU number and the time slot i the most approaching and be no more than the customer service of available RU number, perhaps choose one and take RU number user still less, then this integrative action finishes.
In the present embodiment, suppose for TS
1-TS
K, the resource sum of each time slot is M RU, that is to say, and each time slot can provide M spread spectrum code channel to carry customer service at most.So, can adopt calculating TS as follows
1And TS
N+1In the formula of available RU number:
Available this time slot of RU number=M-is the RU number that switches the user and reserve-used RU number
Wherein, be common signal channel and the shared RU number of the Traffic Channel that is connected CU sum in this time slot with the RU number.
When new user is some real time high-speed rate user, can not be thought of as the RU that switches user's configure reserved according to the design of system, perhaps for switching the RU of user flexibility configure reserved yet.
Resource integrated method of the present invention, be applicable in time division duplex/CDMA mobile communication systems, can make full use of the flexibility of TDD system resource allocation, certain customers in the time slot are transferred in other time slot, to concentrate the surplus resources in a plurality of time slots, distribute to the new user more to resource requirement.Further adopting user in the time slot that priority is high to transfer in other time slot during transfer goes.Time slot priority can be provided with according to the average criterion of load, also can artificially be provided with.
