Embodiment
Below in conjunction with Figure of description the embodiment of the invention is elaborated.
The embodiment of the invention covers for realizing wireless signal, has adopted following method:
Utilize aerostatics to carry base station RRU (Radio Remote Unit, radio frequency remoto module) and antenna lift-off, and RRU is connected to antenna, emission and/or reception subscriber signal;
By the BBU of base station that is positioned over ground and link to each other (Building Base band Unit, baseband processing unit) with said RRU, the base station signal of chain road direction BSC transmission via satellite.
This method utilizes the aircraft platform to carry emergency mobile communication equipment, and mobile communication equipment is changed in the air, is specially adapted to the base station signal passback under the emergency communication environment; Under the situation of can damage in the base station, network interrupting, as when running into natural calamity, set up interim mobile communications network as early as possible, ensure the normal operation of communication network.
Aerostatics is meant that generally proportion is lighter than aircraft air, that rely on the atmospheric buoyancy force lift-off.Can transport flexibly through vehicle-mounted mode owing to aerostatics in the enforcement; And self-contained dynamic power device; Can be active equipment or the device power supplies such as base station RRU on the aerostatics for a long time; The environment that so just can be implemented in no externally fed, no iron tower, no wire transmission recovers down rapidly local mobile communication, and lift-off highly is higher than common iron tower height, and coverage is more extensive.
Fig. 1 lays sketch map for the high-altitude, base station of the embodiment of the invention, and is as shown in the figure, the RRU lift-off, and BBU is placed on ground, can save the load-carrying of aerostatics like this.RRU is placed on aerostatics and rises to the high-altitude, is connected to antenna (for example high-gain aerial) through coaxial cable and power splitter (coupler) etc., emission and/or reception subscriber signal.When the aerostatics relative altitude was 1000 meters, the wireless signal covering radius can reach 50km.
(can reach 1G～2.5G), therefore, can adopt optical fiber to connect between RRU and the BBU, during connection optical fiber is strapped on the mooring line of aerostatics because the data occupancy bandwidth is very big between RRU and the BBU.Certainly, except optical fiber, also can adopt the medium that other can the transmission of high-rate data that RRU is linked to each other with BBU.
Also show the BBU that is placed on ground among Fig. 1 and link to each other with satellite end station, base station signal is passed to BSC via satellite through satellite end station, satellite main website.
For improving the access capacity that the high-altitude lays the base station, can place a plurality of RRU at aerostatics in the enforcement, through increasing the quantity of the RRU on the aerostatics, increase user's access capacity.
When being placed with a plurality of RRU on the aerostatics, a BBU on these a plurality of RRU and ground can have multiple connected mode.Y-connection mode for example shown in Figure 2, each RRU among promptly a plurality of RRU is parallel to be provided with, and links to each other with a BBU on ground respectively; Chain type connected mode and for example shown in Figure 3, each RRU among promptly a plurality of RRU links to each other successively, links to each other with a BBU on ground again.Wherein, under the Y-connection mode, can also utilize transferring equipment to realize that classification connects, with the quantity of further increase RRU, as shown in Figure 4.When connecting RRU and BBU with optical fiber, the Y-connection mode needs multifiber, and the chain type connected mode only needs an optical fiber.
In addition, when being placed with a plurality of RRU on the aerostatics, be the consumption that reduces the aerostatics power supply; Prolong the suspension time of aerostatics, can monitor the operating state of each RRU on the aerostatics, according to the operating state of each RRU; The access quantity of control RRU realizes the flexible expansion of base station access capacity.Insert what of quantity according to the user, can close temporary transient no standby device in the aerostatics.For example the few idle period of user can keep 1 RRU, closes other RRU; In the period that the user increases, opening corresponding RRU equipment one by one.
Based on same inventive concept, the embodiment of the invention also provides a kind of base station system, and this base station system is the distributed base station framework, as shown in Figure 5 comprising:
Radio frequency remoto module RRU501 is positioned on the aerostatics and goes up to the air, be positioned over aerostatics on the antenna that goes up to the air be connected, be used for emission and/or receive subscriber signal;
Baseband processing unit BBU502 is positioned over ground, links to each other with RRU, and link transfers to base station controller BSC with base station signal via satellite.
Among the embodiment, said RRU is connected through optical fiber with BBU.
Among the embodiment, said RRU is a plurality of.
Among the embodiment, among said a plurality of RRU, each RRU is parallel to be provided with, and links to each other with a BBU on ground respectively; Or each RRU links to each other successively, links to each other with a BBU on ground again.
Among the embodiment, base station system shown in Figure 5 can also comprise:
In the embodiment of the invention, utilize aerostatics to carry base station radio frequency remoter module RRU lift-off, and RRU is connected to antenna, emission and/or reception subscriber signal; The base station baseband processing unit BBU that is positioned over ground and links to each other with said RRU, the base station signal of chain road direction base station controller BSC transmission via satellite, thereby the good covering of realization wireless signal; And; Compare with existing fixed base stations, can tackle contingency condition, during like the generation major natural disasters; The situation that surface large area mobile communication base station, ground is ruined or power delivery is interrupted; Through mobile communication equipment is changed in the air, set up mobile communications network maneuverability, ensure that communication network normally moves.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
