Background technology
Development along with mobile communication, particularly along with the 3G (Third Generation) Moblie network Large scale construction and the arriving in the epoch of use, because 3G network is devoted to provide type abundant, the wireless data service of two-forty and high quality-of-service, and because in 3G network based on CDMA, different business has different geographical distributions, coverage and service quality under same wireless environment, and this makes that how describing interior user of certain regional the present and the future period accurately uses the distribution situation of miscellaneous service to become the prerequisite and the necessary condition of building an elaboration wireless network.In the 3G wireless network planning, predict and describe the service distribution and the development condition in somewhere, the most important thing is to describe accurately the situation of this area's user distribution and different user use different business.Because age, occupation, economic situation even interlocal difference make the different network users different to the behaviour in service of wireless network, there is bigger difference in dissimilar users on position distribution and professional the use; In addition, when the user used network access by wireless terminal to carry out a certain business, different business also was different to the situation that takies of wireless network resource (i.e. carrying).Therefore, the user distribution and the professional behaviour in service in a certain area be described, at present unique utilizable be exactly the business development situation and the related data of 2G network.
Summary of the invention
The object of the invention just is to utilize the business development situation and the related data of existing 2G network, provides a kind of accuracy the high 2G service data guiding method that is used for 3G planning simulation software.
For achieving the above object, the present invention can take following technical proposals:
The 2G service data guiding method that is used for 3G planning simulation software of the present invention comprises the steps:
The first step, according to concrete form of existing network business survey file and related content requirement, existing network is surveyed, reconnoitre content and comprise: 2G website and site information are latitude and longitude information; The transmitting power of broadcast channel or pilot channel; The busy hour calling amount of speech business and the throughput of data service; The Downtilt of each 2G base station, azimuth information, propagation model and cutting off rate; Write in the existing network business survey file reconnoitring the information that obtains;
Second step, in 3G planning simulation software, importing digital map and the selected concrete zone and relevant known conditions that need carry out the emulation of 3G wireless network planning;
The 3rd step, importing existing network business survey file, and on numerical map, show the 2G base station;
The 4th the step, utilize known sites distribution situation, BCCH transmitting power and 2G propagation model to determine each website overlay area;
The 5th step, the voice-and-data traffic information in the existing network business survey file is distributed weights according to certain atural object respectively is that unit is spread across corresponding overlay area with the grid, generates speech business density map layer and data service density map layer;
The 6th step, because the 3G business is carried out with the 2G business and is carried out the bigger difference of existence, need revise, promptly adopt scale factor that the 2G traffic density figure layer that generates is handled and generate 3G traffic density figure layer.
2G propagation model in described the 4th step is meant and carries out the 2G propagation model that the propagation loss predicted correction is crossed; When utilizing the 2G propagation model to determine each website overlay area, need to consider the antenna direction and the angle of declination information of 2G website.
When spilling business in the 5th step in carrying out 2G website overlay area, the service distribution information of utilizing CDMA1X is to remedy the few deficiency of data distributed intelligence amount among the 2G.
The invention has the advantages that and have great flexibility and very high accuracy, go for the importing of various systems all kinds existing network traffic data, can utilize the 2G service distribution that the 3G business in each special area is generated independently service distribution figure layer as required, direct and accurate with respect to other traffic density generating mode.Be with a wide range of applications, utilize the present invention that the 2G business datum is imported in the 3G planning simulation software, not only can be used for improving the precision of 3G wireless network planning, improve the quality of the network planning, also can be applicable in the optimization and evaluation and test of existing network; In addition, this method is that the theoretical research of wireless network and network simulation aspect also have high using value and application prospects.In a word, the present invention has realized wireless network user is distributed and the accurate definition of business demand with rich functions and flexibility greatly, it be a kind of science, efficiently, 3G service distribution define method flexibly.
