Abstract
The invention discloses a mobile communication POI (Point Of Interface), comprising four combiners, wherein the third combiner and the fourth combiner are respectively connected with a signal receiving terminal and a signal transmission terminal. After signals of multi-path different communication systems are input from the respective corresponding signal receiving terminal, the signals are combined into one path and are output from the signal transmission terminal to a user terminal for signal transmission. The signals of the user terminal are reversely transmitted by the signal receiving terminal, and are transmitted to the corresponding communication systems by various kinds of the signal receiving terminals. The invention can totally meet the requirements of no interference after the signals entering the common port, and little combiner loss, reduce the complex degree of indoor wiring simultaneously, and bring great convenience for future maintenance work.
Description
Technical field
The present invention relates to the communications equipment field, be specially a kind of mobile communication POI (Point Of Interface).
Background technology
At present domestic communications industry is more and more flourishing, and along with the progress of the 3G communication technology, the 3G product in the application in market also more and more widely.Because the business that 3G is abundant will have the traffic about 60%--70% to occur in indoor in the 3G epoch.Carrying out 3G indoor distributed system upgrading, fully absorb telephone traffic, lasting, the professional user of raising of stable data is provided acceptance and satisfaction to 3G, promote the wireless network overall performance, is the needs of common carrier corporate strategy development.Home communications operator mainly contains China Mobile, CHINAUNICOM, three companies of China Telecom, the employed communication signal difference of different communication operators, therefore when indoor the conversation, if run into different signals of communication, need set different communication receiving platforms, on indoor ceiling, also need to install a plurality of omnidirectional antennas, lay a plurality of plate antennas, many coaxial cables in need be in elevator as in elevator hoistways, using also.This has caused the waste of resource, simultaneously because the communication receiving platform is too much, also can cause wiring complicated, is unfavorable for maintenance work in the future.
Summary of the invention
The purpose of this invention is to provide a kind of mobile communication POI (Point Of Interface), can realize that multiple communication signal is combined into one the tunnel and inputs to user terminal, be combined into one the tunnel with the signal separately of user terminal and be back in the different communication systems, run into the problem that different communication signals need be set up different communication signal receiving platforms when effectively having solved indoor conversation.
In order to achieve the above object, the technical solution adopted in the present invention is:
Mobile communication POI (Point Of Interface), it is characterized in that: include four mixers, the 3rd mixer wherein, the 4th mixer is connected with a signal receiving end and a signal transmitting terminal respectively separately, first mixer and the 3rd mixer, second mixer is electrically connected the realization transfer of data respectively with the 4th mixer, also include two electric bridges, described first, second mixer connects with the different inputs of two electric bridges by data wire respectively separately, wherein two of first electric bridge outputs are connected with GSM signal terminal respectively, be connected with two isolators between each output of described electric bridge and corresponding GSM signal terminal, two outputs of second electric bridge are connected with TETRA signal terminal and CDMA signal terminal respectively, the output of described TETRA signal terminal and second electric bridge, be serially connected with two isolators and a filter respectively successively between another output of CDMA signal terminal and second electric bridge, described the 3rd mixer, the 4th mixer also is connected by the input of data wire with the 3rd electric bridge, is connected with a plurality of 3G signal terminal on the output of described the 3rd electric bridge; The signal of multichannel different communication systems is after each self-corresponding signal terminal input, being combined into one the road exports user terminal to from described signal transmitting terminal and carries out signal transmission, the signal of user terminal is got back in each self-corresponding communication system through described various signal terminal then by the signal receiving end reverse transfer.
System signal separation scheme of the present invention is last/descending separation scheme.Descending scheme is presented as that multichannel unification road exports user terminal to from the signal emission port and carries out the signal downlink covering, up scheme is presented as that the signal of user terminal then is to carry out the passage reverse transfer by signal receiving end, gets back to communication system separately then along separate routes.
The present invention can be used for indoor, outdoor, tunnel and station several parts zone, wherein the communication system that the tunnel need cover between the station has Digital Clustering, telecommunications CDMA, the GSM900 of UNICOM, mobile GSM900,3G system.The present invention utilizes efficient mixer that each operator's uplink and downlink radiofrequency signal is effectively closed road and shunt, can satisfy fully and not disturb mutually after signal enters common port, and the requirement that combination loss is little, reduce the complexity of house wiring simultaneously, greatly facilitated maintenance work in the future.
