Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of many base station beacon identifications of broadcasting and TV frequency spectrum ultra-narrow band Internet of Things
Method.
Background technology
Wireless communication system is widely disposed to provide various types of communications, for example, by this radio communication system
System provides voice and/or data.One typical wireless communication system or network, can be provided to one or more shared resources
The multiple access of (for example, bandwidth, transmit power etc.).For example, system can use various multiple access techniques, such as：Frequency division
Multiplexing (FDM), time division multiplex (TDM), code division multiplexing (CDM), OFDM (OFDM), high-speed packet (HSPA, HSPA+)
Etc..Additionally, wireless communication system can be designed for realizing one or more standards, such as I S-95, CDMA2000, I S-
856th, W-CDMA, TD-SCDMA and other standards.In the wireless communication system of reliable design, must to particular data transmission parameter
Must give and pay special attention to.For example, in the conventional wireless communication system, base station power is that the topological detailed of place is set according to it
Knowledge and be fixedly installed (for example, power is general relatively low to alleviate congestion in intensive Metropolitan Area, and the mesh in the sparse area in rural area
Mark is mainly to provide covering).So as to manage inter-cell interference by carefully choosing transmit power.In plug and play type network
In, such as in 802.11, power is also what is be fixedly installed.When more 802.11 base stations are installed, this can cause serious doing
Disturb problem.Accordingly, it would be desirable to a kind of method and system for mitigating adjacent base station potential interference in wireless environments.It is above-mentioned current
The defect of wireless communication system is only for providing the general view to some existing system problems, rather than for exhaustion.Existing system
The attendant advantages of the other problems of system and various non-limiting examples described herein will become aobvious by following description
And be clear to.
The content of the invention
The technical problems to be solved by the invention are directed to above-mentioned the deficiencies in the prior art, there is provided a kind of broadcasting and TV frequency spectrum ultra-narrow
The band many base station beacon recognition methods of Internet of Things.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of broadcasting and TV frequency spectrum ultra-narrow band many base station beacon recognition methods of Internet of Things, all of base station all sends fixed frequency range
Beacon channel, by way of intercepting beacon, determines the frequency range that ultra-narrow is used with Internet of Things, believes comprising system in the beacon
Breath.
Further, time-multiplexed mode is taken to manage the transmission of base station beacon channel.
Further, beacon period be made up of a sequence of beacon bag and remaining space.The number of beacon bag depends on supporting
Disappear the number of the base station disturbed to each other.
Further, each beacon period of base station have 12 time slots, all base stations send beacons in a cycle
The number of bag is 5.
Further, the RSS I of beacon were tested in base station before being launched, if RSS I are more than predetermined threshold, base
Standing just reduces transmission power, if RSS I are less than predetermined threshold, or lost beacon, just increase transmission power.
Further, network detects the RSS I of the beacon for receiving and records, if network received quantity is more than M
The individual UL bags higher than predetermined sensitivity, with regard to emissioning controling signal to base station, it is desirable to reduce transmission power.
Beneficial effects of the present invention are：Many base station beacon recognition methods of the invention can enter to the beacon channel of many base stations
The rational distribution of row and management, are effectively identified to beacon.
Brief description of the drawings
Fig. 1 is the broadcasting and TV frequency spectrum ultra-narrow of the invention band many base station beacon recognition methods schematic diagrames of Internet of Things.
Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
As shown in figure 1, a kind of broadcasting and TV frequency spectrum ultra-narrow band many base station beacon recognition methods of Internet of Things, it is characterised in that all
Base station all send the beacon channel of fixed frequency range, by way of intercepting beacon, determine the frequency range that ultra-narrow is used with Internet of Things,
System information is included in the beacon.
Time-multiplexed mode is taken to manage the transmission of base station beacon channel.
Beacon period is made up of a sequence of beacon bag and remaining space.The number of beacon bag depends on offsetting doing to each other
The number of the base station disturbed.
There are 12 time slots each beacon period of base station, and the number that all base stations send beacon bag in a cycle is
5.
The RSS I of beacon were tested in base station before being launched, if RSS I are more than predetermined threshold, base station just reduces hair
Power is penetrated, if RSS I are less than predetermined threshold, or beacon is lost, just increase transmission power.
The RSS I of beacon that network detection is received simultaneously are recorded, if network received quantity more than M higher than pre-
The UL bags of sensitivity are determined, with regard to emissioning controling signal to base station, it is desirable to reduce transmission power.
In the present embodiment, system uses 200KHz frequency spectrums, and broadcasting and TV cooperation, but, the frequency range of broadcasting and TV has in the whole nation to be made
With neither one frequency can be with general in the whole nation.So, in different provinces, it is necessary to use different frequency ranges, and need to jump
Frequently.Therefore, using letter calibration method, automatic identification network can effectively use the frequency spectrum of broadcasting and TV.
In gsm networks, the frequency range for having multiple 200kHz can be distributed, in ultra-narrow band Internet of Things, unlike, only
One frequency range, all of base station must simultaneously intercept same 200kHz frequency ranges.Ultra-narrow band internet-of-things terminal is also not adhered to net
Network, also not with Network Synchronization.
The present invention determines the 200kHz frequency ranges that ultra-narrow is used with Internet of Things, all of base by way of intercepting beacon
Stand and all send beacon channel.The carrier wave for using is the centre frequency of 200kHz frequency ranges.System information is included in beacon.Beacon sends
Speed is 8000bps, and power is+43dBm (20W).
Beacon period is made up of a sequence of beacon bag and remaining space.The number of beacon bag depends on offsetting doing to each other
The number of the base station disturbed.Therefore, using 5/12 as basic Interference Cancellation set.
Many base station beacon recognition methods of the invention can reasonably be distributed and managed to the beacon channel of many base stations,
Effectively beacon is identified.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
