Description
Technical field
The present invention relates to the communications field, in particular to a kind of means of communication, apparatus and system.
Background technology
In most of global Railway Mobile Radio systems（Global system for Mobile Communication
For Railways, referred to as GSM-R）In project, the covering of signal in tunnel usually by alms giver's macro base station, optical fiber repeater and
A few part compositions of leaky cable, that is to say, that the covering in tunnel relies primarily on the remote termination of optical fiber repeater and leaky cable point
After section connection, and entire tunnel is disposed, so as to complete the covering of the wireless signal in entire tunnel.
The common wireless signal coverage mode based on macro base station and repeater in the relevant technologies is introduced below, is schemed
1 is according to the schematic diagram of one of the common coverage mode of the relevant technologies, as shown in Figure 1, macro base station（Radio frequency alms giver stands）By with
The near-end machine connection of repeater provides radio-frequency signal source, and then repeater near-end machine passes through optical fiber and several repeater remote termination phases
This radiofrequency signal is zoomed out and is amplified by Lian Hou, while each repeater remote termination reveals cable and antenna by connection（Hole
Mouth side）Complete the covering of entire tunnel radio signal.But under coverage mode shown in Fig. 1, if event occurs for near-end machine
Barrier then will not have wireless signal to cover, therefore the Reliability comparotive of this networking mode is low in entire tunnel.
Fig. 2 is according to two schematic diagram of the common coverage mode of the relevant technologies, as shown in Fig. 2, there is 2 sets of macro base stations（It is macro
Base station 1 and macro base station 2）It stands as radio frequency alms giver, is connected respectively to 2 near-end machines of repeater（Near-end machine 1 and near-end machine 2）,
And this 2 near-end machines are connected respectively to each repeater remote termination by optical fiber simultaneously.Proximally if machine 1 provides macro base station 1
RF spot for f1, the RF spot that proximally machine 2 provides of macro base station 2 is f2, then letting out in tunnel under normal circumstances
Electric leakage cable then exists simultaneously the two frequencies of f1 and f2.At the same time, f1 and f2 is set at the near-end machine of repeater centainly
Difference（Such as poor 3dB）, then there will be the last an one weak 2 road wireless signal in tunnel, if some is near in this case
Terminal breaks down, then still has another near-end machine that can ensure that remote termination has some radiofrequency signal to send out（F1 or f2）,
So as to ensure that wireless signal still has covering in tunnel.
Although networking shown in Fig. 2 and coverage mode can solve to cause entirely due to the Single Point of Faliure of repeater near-end machine
To there is no the problem of wireless signal covering in tunnel, so as to improve the reliability of wireless signal covering, but when near-end machine 1（It is false
If f1>f2）There is terminal while breaking down（Terminal works are on f1 at this time）When carrying out certain business（Such as it converses）,
May result in terminal and call drop and off-grid occur, then re-started in itself by terminal network selection and undergo more than ten seconds to tens seconds when
Between after, can just adhere again to near-end machine 2 offer f2 on.It is above-mentioned in this case, will certainly be to railway wireless train tune, especially
It is that the business such as the row control of high ferro cause great security risk, is easy to cause major traffic accidents.
With multi-transceiver technology and the gradual maturation of distributed base station in recent years, also it is being gradually introduced in present GSM-R projects
Distributed base station carries out the deployment in tunnel.Fig. 3 is according to three schematic diagram of the common coverage mode of the relevant technologies, is such as schemed
Shown in 3, distributed base station is introduced directly into tunnel, and by the indoor Base Band Unit of distributed base station（Building
Baseband Unit, referred to as BBU）Substitute the near-end machine and Remote Radio Unit of former repeater（Radio Remote
Unit, referred to as RRU）The remote termination of former repeater is substituted, and BBU is directly connected with BSC, is not only reduced for networking in this way
The access layer of the original repeater of level-one, reduces trouble point, while is avoided that again unavoidable in traditional repeater application
Technology disadvantage, such as repeater is to noise, sensitivity interference of donor base station etc..
Under normal circumstances, BBU 1 and BBU 2 is main and standby relation, i.e. BBU 1 works, and BBU 2 is backed up.When BBU 1 occurs
During failure, business will be switched on BBU 2, but distributed base station falls in BBU grades of protection using whole RRU at present
The mechanism changed, that is to say, that in protection switching process, it still will appear situation about being covered in tunnel without signal, and no signal
Time can continue tens seconds to a few minutes etc., the relatively low tunnel coverage technology of this reliability, will certainly be to railway wireless train
The row control business that reconciles causes strong influence.
For tunnel coverage technology in the relevant technologies reliability it is relatively low the problem of, not yet propose effective solution party at present
