Abstract
A mobile internet user air interface occupying period calculation method based on signal analysis in a general packet radio service (GPRS) environment is realized by adding a novel entity between a packet data service node (PDSN) and the Internet on existing network architecture. Two traditional methods, namely carrying out a drive test (DT) in an air interface and querying base station equipment (both the methods have drawbacks), can be used for acquiring information about air interface resources occupied by a mobile internet user. Currently, most operators build 3rd-generation (3G) core network signal monitoring systems already, and if air interface resource occupying circumstances can be calculated through the core network monitoring systems, building cost of a monitoring system can be significantly reduced. With the aid of the 3G core network signal monitoring systems built by the operators already, under the premise that no DT instrument is used or a base station resource query function is opened, only by utilizing the signal analysis, a system can map a terminal air interface occupying process to a core network link building process, and then a 3G mobile internet user air interface occupying period can be calculated. Through the calculation method, the 3G air interface resource occupying conditions can be simply, conveniently and quickly calculated so that the building cost of the air interface resource monitoring system can be significantly reduced.
Description
Technical field
The present invention proposes a kind of QoS method for routing based on quantum genetic algorithm take IP network of future generation as the basis.Next generation network not only will provide traditional " doing one's best " type service, and the service that will provide certain QoS to guarantee.The QoS routing issue of multiple constraint is np problem.Employing is based on the genetic algorithm of quantum calculation principle, use quantum bits of encoded chromosome, utilize quantum probability amplitude form to make a quantum chromosomes characterize simultaneously the information of a plurality of states, cave in and bring abundant population by the simulation quantum, introduce the quantum variation so that population is evolved to defect mode with large probability, thereby accelerate the speed of QoS routing convergence.The method relates to the technical fields such as QoS route, genetic algorithm, next generation IP network network.
Background technology
In order to obtain the information of mobile Internet CU interface-free resources, operator generally takes following two kinds of conventional methods.One of method is by carrying out drive test in the side of eating dishes without rice or wine, thereby obtains the situation that interface-free resources takies.This method only can the drive test sampling obtain partial information on the one hand, needs on the other hand a large amount of tester's outdoor works, takes time and effort; Two of conventional method is by the inquiry base station equipment, obtain the interface-free resources occupied information, but this method instrument is fit to use under specific circumstances, because the base station side load is very heavy, can't bear a large amount of query manipulations, and base station equipment is not preserved this type of information, such as needs, necessary provisional configuration, and easy consumption base station resource affect regular traffic.
The built 3G core network signalling monitoring system of having sent out in most of operation commercial city takies situation if can extrapolate interface-free resources by the core net monitoring system at present, will greatly reduce the monitoring system construction cost.The 3G core network signalling monitoring system of having built well by operator, by the projectional technique of describing among the present invention, the simple and efficient 3G interface-free resources of extrapolating takies situation, need not to adopt the inquiry of drive test and base station, thereby significantly reduces interface-free resources monitoring system construction cost.
Summary of the invention:
Technical problem: the objective of the invention is the 3G core network signalling monitoring system built well by operator, projectional technique by a kind of signalling analysis, do not using any drive test instrument, or under the prerequisite of open base station resource query function, terminal is eated dishes without rice or wine to take process be mapped as core net link setup process, can extrapolate the duration information of eating dishes without rice or wine of 3G mobile Internet CU, thus decrease interface-free resources monitoring system construction cost.
Technical scheme: the present invention is take the CDMA2000 network as example, on the framework of information is eated dishes without rice or wine in existing eating dishes without rice or wine/base station side collection, as shown in Figure 1, proposed a kind of at the eat dishes without rice or wine framework of information of core net PI side collection, as shown in Figure 2.As seen, on existing framework, by the drive test instrument, the mode obtaining information of artificial training in rotation, bothersome effort, and the collection of can only sampling, what obtain is the information of part; If inquire about at base station equipment, will increase load of base station, thereby have influence on regular traffic, and the base station do not preserve this type of information, also need provisional configuration.If adopt at the eat dishes without rice or wine framework of information of core net P1 side collection, the collection point is single, dispose simply, so that construction cost reduces greatly, it can gather comprehensively, cover the whole network, information completely, in parallel by bypass, can not have influence on the Network operation, and need not human assistance, all calculated by software and algorithm.
The system that accompanying drawing 3 has provided this paper forms, and as seen is newly equipped with to be equipped with flow information collection entity, signalling analysis entity, hind computation entity and information storage entity.Each several part entity practical function is as follows:
Signalling analysis entity: the agreements such as GPRS are resolved;
The key method of this paper is to utilize all core network signalling information that collects, and terminal is eated dishes without rice or wine to take process be mapped as core net link setup process, thereby can extrapolate the duration information of eating dishes without rice or wine of 3G mobile Internet CU.Be implemented as follows.
Accompanying drawing 4 has provided professional concrete signaling process.Idiographic flow is described below:
1, terminal online to base station equipment application interface-free resources, is sent the PDP connection request after the success;
2, RAN passes to equipment of the core network PDSN/GSN with request;
3, equipment of the core network PDSN/GSN activates PDP and connects, and sets up the PDP passage for terminal and core net, and terminal begins online;
4, terminal is off line, sends the PDP releasing request;
5, RAN passes to equipment of the core network PDSN/GSN with request;
6, equipment of the core network PDSN/GSN discharges the PDP connection, please return to discharge response to terminal;
7, the terminal success is off line, discharges interface-free resources.
By this signaling process analysis as can be known, the duration that interface-free resources takies is initiated from terminal to network resource request and the PDP activation, until terminal is sent the PDP releasing request, resource discharges to be finished.Accompanying drawing 5 has provided concrete Time Calculation flow chart.Concrete time index is defined as follows among the figure:
1, T1: mobile phone sends and activates the duration that is connected between this request arrival equipment of the core network, and begun to take to eat dishes without rice or wine this moment;
2, T2: equipment of the core network returns link setup and responds mobile phone and receive this response;
3, T3: connection is successfully established the whole online session of mobile phone duration
4, T4: mobile phone sends the duration that this request of release connection request road arrives equipment of the core network;
5, T5: equipment of the core network returns to discharge to respond receives this response to mobile phone, and this moment, mobile phone discharged interface-free resources.
Definition of T is that mobile phone terminal takies the duration of eating dishes without rice or wine in addition, then satisfies following formula:
T＝T1+T2+T3+T4+T5
Definition of T again ' be the time that core network signalling collection and analytical equipment can get access to, following formula is then clearly arranged:
T’＝T2+T3+T4
Because T1 and T5 are in fact the propagation delay times that terminal arrives equipment of the core network, generally, these two time delay indexs all are Milliseconds, eating dishes without rice or wine to take in the computational process of duration, can ignore, therefore:
T≈T’＝T2+T3+T4
And the difference that T ' only needs the arrival of signalling analysis equipment records PDP activation request and PDP release response to send these two time points gets final product.
