Net authentication, and to registered running number (such as: D1303) function number, engine number (such as: 30200031) function number to GSM-R
VU voice unit carries out kick out, then passes through local No. MSISDN (such as: 180 ... 37) re-registering running number function number again
With engine number function number, to realize voice call communication function.
After troubleshooting, after control unit confirms that GSM-R VU voice unit works normally, GSM-R data cell is being controlled
Under the control of unit, current running number (such as: D1303) function number and engine number are nullified (such as: 302 00031) function number, GSM-R
VU voice unit re-registers running number function number and engine number function number under the control of the control unit, restores original normal work
Mode.
2, redundancy scheme when GSM-R data cell failure
The condition of redundancy scheme when realization GSM-R data cell failure: 1) core net: DNS and RADIUS increases corresponding
Distribute IP address function；2) it is inserted with a SIM card in GSM-R VU voice unit and GSM-R data cell, two SIM cards have simultaneously
It is standby to support Speech Communication function and data communication function, there is No. MSISDN, and be provided with to other No. MSISDN progress FM
The permission and function of (Follow Me) kick out.
When the GSM-R data cell or CAN interface converting unit connected to it break down, CIR equipment into
Entering the operating mode that degrades (as shown in Figure 3b), control unit judgement and control GSM-R data cell exit data communication between vehicle ground,
The function of data communication between GSM-R vehicle ground is completed by the GSM-R VU voice unit worked normally；
Later, by the GSM-R VU voice unit that works normally using virtual engine number (such as: 1,302 00031) as user number into
Row registration and activation obtain a virtual IP address (such as: 10.13.2.2) from RADIUS, and pass through the virtual IP address
Data communication is carried out with GRIS or GROS；
After troubleshooting, after control unit confirms that GSM-R data cell works normally, GSM-R data cell is with reality

IP address and GRIS or GROS carry out data communication, and GSM-R VU voice unit is stopped using virtual under the control of the control unit
IP address (such as 10.13.2.2) and GRIS or GROS carry out data communication.
Realize the dominant alternative of GSM-R data cell redundancy scheme:
When CTC sends traffic order and route schedule information to CIR by GRIS, there are two kinds of possible situations:
(1) currently affiliated CTC passes through GRIS to CIR transmission information to train.In such cases, by updating in current GRIS
CIR engine number and IP address corresponding lists can normally realize correlation function.
(2) CTC of train operation ahead sends information to CIR by corresponding GRIS in advance.At this point, due to train operation
The GRIS of front road bureau not yet obtains the corresponding relationship of CIR engine number and IP address, if the GRIS is only according to the engine number of CIR
The IP address of CIR is obtained to DNS query, it is possible to there is the IP address obtained and the inconsistent situation of CIR real ip address, from
And it will appear the case where information sends failure.
It is practical engine number to realize that running number is checked in information for the above demand, but fills in virtual locomotive when degradation
Number IP, processing scheme can be taken.Divide equally in RADIUS to the corresponding engine number of CIR and virtual engine number and matches the same IP
Address, that is, identical IP address is distributed to 2 different users.
When normal work, the GSM-R data cell of CIR is obtained using the engine number (such as 12345678) of oneself from RADIUS
The IP address (such as 10.14.100.1) of oneself realizes relevant data transmission by GSM-R data cell.At this point, CTC/TDCS
When sending data to the CIR, GRIS initiates to inquire using 12345678 engine numbers to DNS, and the address that DNS is returned is
10.14.100.1, data can be normally sent to the GSM-R data cell of the CIR by GRIS, normally realize correlation function.
When GSM-R data cell breaks down, in Fig. 5, the GSM-R VU voice unit of CIR uses virtual engine number (such as
1 12345678) to RADIUS application IP address, and RADIUS still distributes same IP address to the GSM-R VU voice unit at this time
(i.e. 10.14.100.1).Hereafter, the GSM-R VU voice unit that will be considered that the CIR in network is validated user, to 10.14.100.1
The data that address is sent can all be sent to the GSM-R VU voice unit of CIR, to realize the superfluous of CIR GPRS data transmission
It is remaining.At this point, if desired CTC/TDCS sends data to the CIR, GRIS still uses 12345678 engine numbers to look into DNS initiation
It askes, the address that DNS is returned is still 10.14.100.1, and GRIS can send the data to the GSM-R VU voice unit of the CIR, real
Correlation function under existing CIR functional unit redundancy condition.
Above scheme of the invention can adequately utilize existing module resource in the case where not increasing new unit, increase
The strong reliability of CIR communication system, in single module failure can intelligent measurement failure, and stand-by unit is taken to substitute work
Make, works normally CIR and use.Thus the unnecessary parking phenomenon due to caused by GSM-R unit is avoided, and reduces module replacing
The various maintenance works of bring.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
