Description
Technical field
The present invention relates to mobile communication technology, more particularly to a kind of NB-IoT wireless network deployment methods based on LTE.
Background technology
In recent years, IoT is quickly grown, and world's all things on earth can be connected with each other by internet, is continued to develop in IoT business
While the Internet of Things communication technology continue to develop.But, traditional mobile communication technology can not meet increasing thing
Networking service demand, NB-IoT arises at the historic moment.NB-IoT, which has, extensively to be covered, Large Copacity, low-power consumption, the characteristic of low cost,
Important branch as all things on earth internet.NB-IoT can be deployed directly into GSM, UMTS or LTE network, realized smoothly
Upgrading.At present, NB-IoT standards are ripe, and industrial chain is also quickly developing end to end, and this is the portion of NB-IoT networks
Condition has been established by administration.
At present, NB-IoT designs are based on existing mobile cellular network, and identical hardware may be reused, and share frequency spectrum
And in the absence of interference.This allows the rapid deployment of the NB-IoT using existing infrastructure.But, for compared with new equipment
Website, NB-IoT can be supported by software upgrading.However, older equipment can not support LTE and NB-IoT simultaneously.Institute
With phased deployment NB-IoT base stations, the major way as NB-IoT network designs.For example, according to the network planning, waiting to dispose
LTE base station 1000 is had in region, the base station of the old equipment of removing, which has 900, can dispose NB-IoT, then n=900；By net
Network is emulated and link budget, draws NB-IoT covering radius, and the region where each LTE base station is melted into a grid；In Google
All grids are marked on the earth, the coincidence factor of each grid is calculated, grid of the coincidence factor more than 90% elects a center
LTE base station, draws m=400, by this 400 LTE base stations, as NB-IoT base stations to be disposed, by the net where base station to be disposed
Lattice are used as grid to be disposed；By calculating the deployment preferred value of each grid, according to the NB-IoT network designs recommended value
Descending order is ranked up to NB-IoT grids to be disposed, and obtains priority list；, will according to set predetermined threshold value
Priority is divided into ABC, NB-IoT phased deployments.
The NB-IoT network plannings are mainly by wireless network coverage area, the data traffic of internet of things service, connection
Number, number of users etc. set up user data service traffic model, realize internet of things service demand analysis.By calculating overlay area
The portfolio of 2G/3G carryings, user connects the traffic statistics such as number, determines portfolio highest area as upgrading base station
Priority area.
If carrying out NB-IoT deployment to all LTE base stations only in accordance with network index, it can undoubtedly cause the throwing of Internet resources
Put not enough precisely, so as to cause the waste of Internet resources.Meanwhile, if in NB-IoT first stage of construction, entered only in accordance with network index
Row NB-IoT network designs, are likely to result in the waste of cost of investment.
In summary, current NB-IoT wireless network deployments, if only relying on network index carries out NB-IoT Network Dept.s
Administration, can not obtain Internet resources the most reasonably to utilize, can also cause the waste of fund, influence the hair of internet of things service
Exhibition.
