Description

Can constitute the device of multiple mobile communication equipment and the mobile communication equipment of formation thereof

Technical field

The present invention relates to mobile communication technology, particularly relate to a kind of device and the repeater of formation, little base station and radio frequency remote equipment that constitutes mobile communication equipments such as repeater, little base station and radio frequency remote equipment.

Background technology

Repeater (repeater) is meant a kind of radio transmission transferring equipment that plays the enhancing signal effect in the wireless communication transmissions process, and the typical case of repeater uses the blind area covering that mainly comprises system, suburb covering, the covering along the line of highway, indoor covering etc.The basic function of repeater is exactly a radiofrequency signal power intensifier.The repeater by donor antenna pickoff signals from existing overlay area, isolates the signal beyond the passband by band pass filter in down link, the signal of filtering is transmitted into after power amplifier amplifies once more treats the overlay area; In the uplink path, forwarding antenna receives the signal of the travelling carriage in the overlay area, by band pass filter signal is handled, the signal with filtering is transmitted into corresponding base station after power amplifier amplifies then, thereby reaches the signal transmission of base station and travelling carriage.

The type of existing repeater has optical fiber repeater, RF direct amplifying station and microwave relay repeater etc.Wherein RF direct amplifying station and optical fiber repeater are modal two kinds of repeaters.Be example with the RF direct amplifying station below, briefly introduce the structure and the operation principle of existing repeater:

Fig. 1 is the structure chart of existing RF direct amplifying station, and its operation principle is as follows: at down direction, receive that by donor antenna the downstream signal of base station delivers to power amplifier and amplify, launched by forwarding antenna; At up direction, receive that by forwarding antenna the upward signal of base station is finished simulation frequency conversion work after low noise amplifier amplifies in frequency range selector, the upward signal after filter filtering is with frequency conversion is delivered to power amplifier and is amplified, and is launched by donor antenna.Whole process all is to finish in analog circuit.

Existing RF direct amplifying station is generally integral structure, can't with optical fiber repeater far-end common parts, also can't be smoothly transitted into base station and radio frequency remote equipment according to user's needs.And because RF direct amplifying station generally uses analogue device to realize, consistency is poor in batches, can't large-scale production.

Fig. 2 is the structure chart of existing optical fiber repeater, mainly is made up of near-end machine, optical fiber, remote termination several sections.Its operation principle is as follows: at down direction, after wireless signal is coupled out from the base station, enter the near-end machine, by the electric light conversion, the signal of telecommunication changes light signal into, input to optical fiber from the near-end machine, to remote termination, remote termination transfers light signal to the signal of telecommunication, and amplification signal through Optical Fiber Transmission, the signal of telecommunication is sent into transmitting antenna, the coverage goal zone after amplifying; At up direction, after the signal of travelling carriage emission is received, enter remote termination, remote termination transfers the signal of telecommunication to light signal, to the near-end machine, again by opto-electronic conversion, transfers signal to the signal of telecommunication at the near-end machine through Optical Fiber Transmission, sends into the base station through after amplifying.

In order to reduce the cost of optical fiber repeater, what most of producers used is the analogue transmission technology, general Optical Receivers and the light emission module that uses high power laser reflector and laser receiver to constitute, in use need to adjust the power of generating laser, to overcome the influence of fibre loss to transmitting power.Thereby most of modules of optical fiber repeater far-end and RF direct amplifying station can't be shared, also can't be smoothly transitted into little base station and radio frequency remote equipment.

In existing mobile communications system, in order to solve covering problem, the repeater is adopted in a large number, and according to the CDMA real application data, the ratio of base station and repeater was near 1: 10, and therefore, the number of the repeater in the network is very many.But from now on along with the continuous increase of number of users, channel resource will become new contradiction, because the repeater does not have the function of dilatation, so the repeater can not satisfy the needs that channel demands order benefit increases, and should be replaced by little base station and radio frequency remote equipment with dilatation function.

The principle of little base station is as follows: at down direction, the optical fiber that Radio Link Controller is transmitted in little base station (or E1) conversion of signals becomes original downstream signal, and to downstream signal encode, multiplexing, spread spectrum, scrambling and framing handle, form a downgoing baseband signal, finish the conversion of intermediate-freuqncy signal then, and downstream signal is launched by power amplifier to radiofrequency signal; At up direction, the upward signal of sending from aerial receiving mobile, this radiofrequency signal is converted to intermediate-freuqncy signal, intermediate-freuqncy signal is converted to digital baseband signal through rate adapted, shunt processing, power adjustment, again this digital baseband signal is carried out demodulation, decoding processing, form Frame Protocol (FP) packet format,, be sent to Radio Link Controller by optical fiber through framing and opto-electronic conversion.

Radio frequency remote equipment can be moved the coverage of base station to other place, thereby increases coverage.If be used for dilatation, can adopt the base station that number of users is less to tell a radio frequency remote equipment and absorb the user, thereby reach the purpose of dilatation to the many hot zones of user.

The principle of radio frequency remote equipment is as follows, at down direction, the light signal that the base station is transmitted reverts to the signal of telecommunication, isolate baseband signal and control signal, processes such as carrying out power control, close the road, data are adaptive, and convert digital signal to intermediate-freuqncy signal, convert intermediate-freuqncy signal to radiofrequency signal then, and downstream signal is launched by power amplifier; At up direction, the upward signal of sending from aerial receiving mobile, convert radiofrequency signal to intermediate-freuqncy signal, be converted to digital baseband signal through rate adapted, shunt processing, power adjustment again, the control answer signal is mixed framing with up baseband signal, convert light signal to and pass the base station back.

A kind of mode of network operation cheaply need be sought by operator, but because the upgradability and the extendible capacity of existing repeater are relatively poor, so the dilatation of a lot of repeaters all is that former repeater is removed, operator purchases new little base station or radio frequency remote equipment more again, has so just wasted operation cost greatly.

In order to realize the low-cost network operation mode of repeater, need the shared a plurality of modules of RF direct amplifying station, optical fiber repeater and little base station or radio frequency remote equipment, with the stock equipment quantity of reduction operator, thus the cost of minimizing operator networking.
