Description
Technical field
The present invention relates to a kind of communication technical field, more particularly to a kind of wireless private network electric power base station plannings of TD-LTE 230
Method.
Background technology
The features such as wireless private networks of TD-LTE 230 have wide covering, transmission rate height, real-time and frequency spectrum strong adaptability, be
The technical way of terminal communication access network.With the arrival in intelligent grid epoch, construction electric power wireless private network is imperative,
In wireless communication technology, China possesses the intellectual property of TD-LTE technical systems, can meet the timing of electric power current and future one
The business development demand of phase, future can also be to 5G evolution, great development potentiality.
Mobile communication is at the initial stage of networking, and customer volume is few, and website is less, and base station covering radius is larger, less to consider
Control of investment and later maintenance, at that time base station construction mainly solve the problems, such as the network coverage, the selection free degree of base station site is big, past
Toward the demonstration without science and analysis, indicate to select base station site with intuition by rule of thumb, as long as sufficiently high, the signal that antenna is hung
Propagate enough remote, the security and stability for thus easily causing base station operation is poor, builds the problems such as maintenance difficulties are big.Therefore for
The construction plan of the wireless private network base stations of TD-LTE 230, should draw former experience and lessons, consider the difficulty or ease of base station construction
Maintenance after degree, opening base station etc., on the premise of the network coverage and traffic demand is ensured, is made rational planning for, is fully examined
Consider the existing infrastructure of Construction Party, determine position and the quantity of base station construction, also to be taken into full account for power industry
Transformer station, business hall and the position of base station can be rented.
Which in addition, during base station construction, how to assess the priority of base station, i.e., preferentially built the need for region
Stand, which region can not build a station temporarily, be all the problem of base station planning should just consider initial stage.Existing base station construction planning
In scheme, operation it is simple using number of users and Regional development level as the judgment criteria of user's request, and advised as base station
The Main Basiss drawn and built.I.e. number of users is more, base station is built in user quality preferably area in advance, accordingly,
Base station is built behind the area that number of users is less, user quality is poor.Although the number and Regional development level energy of number of users
Enough user's requests for embodying this area to a certain extent, but network demand of this perceptual knowledge to user be not specific
Refinement, the demand of potential user is not reflected really, therefore, existing this base station construction programme, which lacks, accurately to be sentenced
The Planning instrument of disconnected foundation and science, may result in really has the regional base station construction priority of demand more rearward.Cause
This, needs a kind of base station planning scheme badly to solve the above problems.
China Patent Publication No. CN104378769, publication date 2015 year 2 month 25 days, the entitled of innovation and creation is based on covering
The TD-SCDMA base station planning point automatic point selection method of lid prediction, this application case discloses base station planning point automatic point selection method core
Heart step includes：Macro base station cell information is gathered, set A is obtained；Cell longitude and latitude maximum and minimum value be simultaneously in set of computations A
Rounded by step-length；Longitude and latitude is split from minimum to maximum by step-length；Matched according to longitude and latitude, obtain set B；To collection
Close the initialization of B attributes；Gather set B grid terrestrial object information etc..Its weak point is to fail to provide for selected base sites
The reasonable proposal of priority is built, is unfavorable for the development of base station construction work, it is impossible to is carried in time for the big region of network demand amount
For the network coverage.
