Description
Technical field
The present invention relates to the communications field, more specifically, relate to a kind of reverse link analysis method and device that is used for the mobile communication network planning design.
Background technology
Along with the fast development of mobile communcations system, the quality of communication network is more and more important, and it directly affects the communication contact between the user.Numerous factors such as the quality of network and system load, mobile subscriber's distribution, mobile subscriber's speed and handoff boundary all have direct relation.Therefore, in order to realize wireless coverage desirable in the service area, as far as possible to reduce and disturb, bring into play the system service quality as far as possible, and under the prerequisite that satisfies quality and capacity, minimize cost, should adopt advanced planning means that network is planned, optimized.
Network planning design is the advanced mode of on software platform network being planned, being optimized, and the project engineer can control, adjust network state by planning software, reach rationally, plan effectively, optimize the purpose of network.
The planning and designing software that in the industry cycle adopts substantially all is to adopt Monte Carlo Calculation machine analogy method at present, simulate the operation conditions of real network by network snapshots repeatedly, in network snapshots each time, terminal (User Equipment, be abbreviated as UE, be called portable terminal or subscriber equipment again) quantity, fixed-site, carry out randomly ordered and whether attempt one by one can access network to terminal, can finally determine state and every network parameter of each terminal through iteration repeatedly.
Accompanying drawing 1 has provided the mature Monte Carlo method main-process stream of present industry, specifically comprises:
Step S102 is provided with network parameter and terminal parameter; In this step, network parameter need be set, comprise base station information, propagation model, system information etc.; Terminal parameter need be set, comprise the COS that terminal can support, the wireless parameter of each COS, hardware parameter of terminal equipment etc.;
Step S104 determines terminal location at random according to the traffic weight, and read the path loss data of this position from database;
Step S106, system resource is all available, the whole zero clearings of terminal transmit power;
Step S108 inserts judgement according to the reverse link method for designing to terminal, output inverse iteration result;
Step S110 analyzes terminal according to the system forward method for designing, output forward direction iteration result;
Step S112 carries out record with result preceding, the inverse iteration computing;
Step S114 judges whether to do next snapshot, and the number of times of general snapshot is provided with in analytical parameters by the user, if completed snapshot number of times reaches the value of setting, and operating procedure S108 then; Can not reach the value of setting if finished the snapshot number of times, then return step S102 again, begin snapshot analysis next time;
Step S116 averages all snapshot results, output planning and designing result; This step averages the result of all snapshot records, obtains final network planning design result.
In the reverse link method for designing of step S108 step, adopt reverse equality alternative manner usually, its flow process as shown in Figure 2:
Step S202, randomly ordered to all terminals of participating in iteration;
Step S204 from first terminal, oppositely inserts judgement one by one to all terminals in lining up, and judges that promptly terminal whether can access network, the output court verdict;
Whether step S206 has next terminal need carry out access attempts in lining up, if having, and execution in step S204 then; If line up in terminal all assignment finish, then carry out next step;
Step S208 judges whether reverse link equality iteration restrains; If iteration restrains, then flow process finishes, output iteration result; If iteration is convergence not, then continue next round and insert judgement, all terminals begin to re-execute step S204 from first;
Step S210, output iteration result.
As can be seen, when oppositely inserting judgement, no matter which kind of service request the terminal initiation is, their access all is an equality from accompanying drawing 2 flow processs.
Early stage in mobile communication development, this traditional terminal alternative manner can be satisfied the demand, but development along with mobile communication, especially enter 3G network after the epoch, service quality (Quality of Service:QOS) becomes a key characteristic of network, that is to say the different COS that require terminal to initiate, in network, obtain the priority difference of resource.Yet, in above-mentioned terminal iterative process, do not consider service quality, therefore can not provide corresponding resource prioritization at different COS.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 3 shows the schematic diagram according to the reverse link analysis method of the embodiment of the invention, may further comprise the steps:
Step S10 will require the terminal of different service quality to attempt accessing mobile communication network successively according to order from high to low, and the terminal that obtains attempting inserting is gathered;
Step S20, set is carried out and is oppositely rejected iteration to terminal;
Step S30 as current snapshot, is used for the planning and designing of mobile communications network with the access state of all terminals and failure record.
The foregoing description provides a kind of computer simulation method that can be applicable to the wireless planning design software, and this method synthesis is considered the service characteristics different to resource occupation of different brackets in the network, so the snapshot that comprises quality-of-service factor is provided.
The snapshot that uses the foregoing description to provide in the middle of mobile communication network planning shown in Figure 1 design can be considered this factor of the desired service quality of terminal, thus analog network operation conditions more accurately, the every performance index of computing network.
Should note, in real network, same terminal can be supported the multiple business service, and in planning and designing, convenient and publish picture clearly for computing, think all that usually a terminal supports a kind of type of service, so in the description below the present invention, with terminal according to grade of service classification be exactly with business according to grade separation, and to the iteration of terminal just with iteration to service business.Service quality is represented with QOS among the present invention.
Step S10 specifically can comprise: read the initial available resources of mobile communications network; Read the desired service quality of each terminal; Attempt the terminal accessing mobile communication network according to service quality order from high to low, the terminal of attempting inserting is added the terminal set; After all terminals of every adding same priority, calculate remaining available resources; When remaining available resources are lower than predetermined value or when having inserted all terminals, finish above-mentioned trial and insert step.
Fig. 4 shows the flow chart according to the reverse link analysis method of the embodiment of the invention, may further comprise the steps:
Step S402, the reading system initial parameter; Comprise and read base station information, network parameter and end side parameter, wherein base station side noise rising thresholding has constituted system of the present invention available resources;
Step S404 reads terminal number and the position distribution of different Q OS (grade of service);
Read the QOS grade of all terminals, and terminal is classified, write down each location information of terminals simultaneously according to the QOS grade.
Step S406 carries out reverse equality iterative process to five-star all terminals of QOS;
The terminal of QOS highest ranking is proposed, carry out reverse equality iterative process (as shown in Figure 2, detailed process is described) in background technology as a terminal group.
Step S408, output inserts successful terminal group Q1 and register system resources left situation;
After the five-star terminal group of QOS executes reverse equality iterative process, with inserting successful terminal output, be designated as terminal group Q1, and record system resource residual state at this moment, here, reverse link system resource mainly is meant the allowance that tolerable inverse noise raises.In the base station side parameter information, demand needs according to the user are provided with parameter: noise rising thresholding, all terminals of whole network insert caused noise rising all can not be greater than this thresholding, therefore behind the senior accessing terminal to network of QOS, can cause the inverse noise of whole network to be raised, if the noise of raising does not reach thresholding, the terminal that next stage QOS then is described still can continue access network, otherwise then whole network capacity has reached thresholding has been set, and can not have new terminal to insert again.
Step S410 judges whether that the terminal of lower QOS needs access network; If have, execution in step S412 then; If no, execution in step S424 then, flow process finishes.
Step S412 judges whether resource has residue; Whether judge promptly that noise raises reaches threshold value, if do not reach, and execution in step S414 then; If reached thresholding, execution in step S424 then, flow process finishes.
Step S414, the terminal of lower one-level QOS is carried out reverse equality iterative process on the basis of system's surplus resources;
Read the number and the positional information of the terminal of the low one-level of QOS, these terminals are randomly ordered, carry out reverse equality iterative process (as shown in Figure 2).It should be noted that when carrying out iteration the initial noise of system is the noise lift-off value that upper level accesses terminal and causes.
Step S416, output inserts successful terminal group, is designated as Q2 and register system resources left situation, and here, reverse link resources mainly is meant the allowance that tolerable inverse noise raises.
Step S418, iterative process is oppositely rejected in the execution that Q1, Q2 group is merged into terminal group Q;
Group Q1 and Q2 are merged into a total terminal group Q (the terminal set that can insert), and in Q, carry out and oppositely reject iterative process, as shown in Figure 5.The noise lift-off value of system when the initial noise of system of oppositely rejecting iterative process is step S416 output.
After step S420, Q group carried out reverse rejecting iterative process, the terminal group of the access success of output substituted Q1, and write down the system resource residual state after iteration is finished;
Step S422 judges whether the terminal of lower QOS, if having, and execution in step S406; If no, then flow process finishes.
Step S424, final result is oppositely analyzed in output.
This embodiment has proposed a kind of brand-new inverse iteration method, can simulate service quality difference in the real system, takies the different characteristics of resource, improves the planning and designing accuracy, and can reach iteration convergence quickly and accurately.
In above-mentioned reverse link analysis method, step S20 specifically can comprise: terminal oppositely inserts judgement successively in closing according to requirement service quality order ordered pair termination set from high to low; If one of them terminal is reversed to insert and is judged to be and can not inserts, then according to from low to high order, from the terminal set, be lower than in the terminal of service quality that this terminal requires, reject the terminal that causes this terminal to insert, and its resource is added available resources; Wherein, all disallowable if all are lower than the terminal of service quality that this terminal requires, this terminal still is reversed to insert and is judged to be and can not inserts, and then this terminal is also rejected, with its resource adding available resources; When judgement is oppositely rejected iteration convergence, finish oppositely rejecting iteration.
Fig. 5 shows the flow chart according to the reverse rejecting iteration of the embodiment of the invention, may further comprise the steps:
Step S502 determine to participate in the access order of the terminal of iteration, and the high terminal order of priority is preceding;
Step S504, whether terminal Ti disallowable? if iteration begins for the first time, then first terminal T1 can be not disallowable; If whether the terminal of back then needs to judge rejected by the terminal of front;
Step S506, terminal Ti carry out and oppositely to insert the judgement flow process, judge that terminal whether can successful access network, or access failure, export court verdict;
Step S508 according to court verdict, judges whether terminal Ti inserts success;
If Ti inserts successfully, then execution in step S520 carries out the access judgement of next terminal; If Ti inserts unsuccessful, carry out next step step S510.
Step S510, according to the QOS grade, whether priority is minimum to judge terminal Ti;
If terminal Ti priority is minimum, execution in step S518 then, terminal Ti access failure; If Ti priority is not minimum, then carry out next step step S512.
Step S512, whether the reason of judging the Ti access failure is that its access causes that the sub-district noise raises in the Active Set and surpasses thresholding, if, then carry out next step step S514, if not, execution in step S518 then, terminal Ti access failure;
Step S514 searches the terminal X that influences the lowest priority that Ti inserts from terminal list;
Searching from terminal list influences that Ti oppositely inserts, and the terminal that QOS priority is minimum is designated as X.The method of searching X is: each terminal all has a coverage cell collection, has write down the sequence number of the sub-district that this terminal can disturb.When terminal Ti access failure, can draw is that the noise of which sub-district raises, and causes Ti not insert, and then according to the coverage cell collection of each terminal, finds the terminal that influences this sub-district.
Step S516 picks out this iteration (being recorded as failure) with X;
Then X is rejected from this iteration, promptly think the X access failure, the resource that X is shared is vacated execution in step S504.
Step S518, terminal Ti access failure;
Does step S520 have next terminal? whether search from terminal list, have next terminal need attempt inserting, if having, then execution in step S504 if do not have, judges then whether iteration restrains.
Step S522 judges whether iteration restrains; If iteration restrains, then flow process finishes, output iteration result; If iteration is convergence not, then continue next round, all terminals begin to re-execute step S504 from first.Concrete, the judgement condition of convergence generally can be 1, as noise rising of the reverse end, the sub-district of adjacent twice iteration variable quantity less than certain threshold value, promptly make an uproar the fluctuation that raises very little the time when the reverse end of adjacent twice iteration, think and withdraw from iterative cycles by iteration convergence; 2, do not restrain when iteration, but iterations causes circulation to stop for preventing that iteration from can't restrain often the time, sets the thresholding of iterations, when iterations equals this thresholding, termination of iterations by force.
Step S524, output iteration result.
In above-mentioned reverse link analysis method, oppositely insert judgement and specifically can comprise: the supported maximum data rate of reading terminals; Calculate the terminal traffic channel emission power of maximum data rate correspondence; According to the ratio of terminal traffic channel emission power in the total transmitting power of terminal, the total transmitting power of computing terminal; Judge whether the total transmitting power of terminal surpasses terminal maximum transmission power thresholding; If do not surpass, judge whether the access of this terminal causes that the noise of Active Set sub-district raises above predetermined threshold, if surpass thresholding, judge that then this terminal access can insert; Judge that the total transmitting power of terminal surpasses terminal maximum transmission power thresholding, the access of perhaps judging this terminal causes that the noise of Active Set sub-district raises above predetermined threshold, then judge whether can the reduction of speed rate for the speed grade that can support according to this terminal, as falling, then fall one-level and the above-mentioned step of circulation execution, otherwise judge that this terminal access can not insert.
Fig. 6 shows the reverse access judgement flow chart according to the embodiment of the invention, may further comprise the steps:
Step S602, the supported maximum data rate Ri of reading terminals;
Step S604, the terminal traffic channel emission power of calculating Ri correspondence;
Step S606 is according to the ratio of terminal traffic channel emission power in the total transmitting power of terminal, the total transmitting power Txi of computing terminal;
Step S608 judges that whether Txi surpasses terminal maximum transmission power thresholding, if do not surpass, and execution in step S616 then; If surpass, execution in step S610 then;
Step S610, the speed grade that can support according to terminal judges whether can the reduction of speed rate, as falling, execution in step S612 then, otherwise step S614 judges the terminal access failure, flow process finishes;
Step S612, first-rate falls in Ri, then execution in step S604;
Step S616 judges whether the access of this terminal causes that the noise of Active Set sub-district raises above thresholding, if surpass thresholding, then step S618 judges that terminal inserts successfully, and flow process finishes; If surpass, execution in step S610 then;
Step S618 judges that terminal inserts successfully;
Step S614 judges the terminal access failure;
Output speed assignment result, process ends.
In the reverse link analysis method according to above-mentioned each claim, mobile communications network is cdma network or HSDPA network.
Planning and designing flow process with a CDMA2000-1X EVDO network is an example below, describes the concrete implementation step of the present invention in detail.
1, reading system initial parameter comprises base station information in the network, day feedforward information, the every power setting in sub-district, noise rising threshold value etc.
3 base stations are arranged in the network in this example, 6 sub-districts, Zone channel Initial Trans is 0 watt, inverse noise rising thresholding 7dB.
2, read the number and the position distribution of the terminal of different Q OS.The number of terminal is that user oneself is provided with, and positional information is according to the weighted value random distribution of various terminals on different atural objects.
The terminal of two kinds of QOS is arranged in the network in this example, and number is respectively 50,100 from high to low, and terminal location is determined at random according to weight.
3, the terminal that QOS is high is carried out reverse equality iterative process.The flow process of concrete oppositely equality iteration as shown in Figure 2.
50 of high QOS terminals are randomly ordered in this example, begin to attempt access network from first, carry out reverse equality iteration, behind the iteration convergence, 34 user's success access networks arranged, other 16 user's access failures.
Record inserts 34 terminals and recording noise lift-off value and available allowance successfully, and is as shown in table 1 below, and wherein oppositely inserting decision method can be as shown in Figure 6:
Table 1 system reverse noise profile
| The sub-district sequence number | 01? | 02? | 03? | 04? | 05? | 06? |
| Noise level (dBm) | -104.2? | -103.5? | -105.6? | -104.5? | -105.1? | -103.8? |
| Available allowance (dB) | 3.5? | 2.8? | 4.9? | 3.8? | 4.4? | 3.1? |
As can be seen from the above table, noise still has available allowance, so the terminal of low QOS can attempt inserting.
4, the terminal that QOS is low is carried out reverse equality iterative process.The flow process of concrete oppositely equality iteration notices that the initial condition that inserts this moment is the terminal accessed network of some high QOS as shown in Figure 2.
100 terminals of low QOS, randomly ordered, execution begins to attempt access network from first, carries out reverse equality iteration, the initial condition of iteration is 34 terminal accessed networks of high QOS, that is to say the value that the initial inverse noise lift-off value of iteration is in the table 1 to be write down.Behind the iteration convergence, the terminal of low QOS has 42 to insert successfully, other 58 access failures.
Record inserts 42 terminals and recording noise lift-off value and available allowance successfully, and is as shown in table 2 below:
Table 2 system reverse noise profile
| The sub-district sequence number | 01? | 02? | 03? | 04? | 05? | 06? |
| Noise level (dBm) | -100.7? | -101.1? | -101.2? | -100.8.? | -100.9? | -100.8? |
| Available allowance | 0? | 0.4? | 0.5? | 0.1? | 0.2? | 0.1? |
As can be seen from the above table, the system reverse noise has reached threshold value substantially.
5, will insert 34 terminals of high QOS successfully and 42 terminals of low QOS and form a set, and carry out and oppositely reject iterative process.Oppositely the flow process of rejecting iteration as shown in Figure 4.
The terminal order of high QOS is preceding, the terminal order of low QOS after, compositing terminal group Q is an initial condition with the noise level in the table 2, from first terminal, carries out the velocity allocating flow process, attempts access network.In step 3, during the accessing terminal to network of high QOS, system noise is very little, so the accessing terminal to network ratio is easier to, now because the terminal of low QOS has also inserted network, so the noise level of system raises, high QOS terminal needs again, and whether judgement can continue successfully to insert, if of course, then continue next step, if because the rising of inverse noise causes the terminal access failure of high QOS, then need according to the method for rejecting in the iterative process, the low QOS terminal that the high QOS terminal of influence inserts is found out, rejected iteration, to guarantee the access success of high QOS terminal.
Finally the result of iteration is, the terminal of 34 high QOS still can successfully insert, and the terminal of low QOS has 29 successfully to insert.
Record inserts 63 terminals and recording noise lift-off value and available allowance successfully, and is as shown in table 3 below
Table 3 system reverse noise profile
| The sub-district sequence number | 01? | 02? | 03? | 04? | 05? | 06? |
| Noise level (dBm) | -100.8? | -101.2? | -101.1? | -100.8.? | -100.7? | -101.2? |
| Available allowance | 0.1? | 0.5? | 0.4? | 0.1? | 0? | 0.5? |
6, the terminal of all QOS is all finished iteration, and output inverse iteration result comprises the successful terminal number of access, reaches reverse throughput, the failure cause of the terminal of access failure, system reverse noise lift-off value etc.
