Antenna 263 received signals send to analog receiver 224 by duplexer 227, and analog receiver 224 will carry out signal amplification, frequency translation, filtering etc. from the radio frequency analog signal that duplexer 227 receives, and give ADC 223 with the analog signal that obtains.
It is digital signal that ADC 223 is used for the analog-signal transitions of analog receiver 224 outputs, and gives digital receiver 222 with this digital signal.Digital receiver 222 will demodulate the uplink business data of travelling carriage from digital signal, and uplink business data is stored in uplink service memory cell 227.The transmitting device 225 of base station 22 will be transmitted to path control deivce 23 with the uplink business data of travelling carriage according to the result of its processor controls 226.
The biography transmitting device 225 of base station 22 receives the downlink service data to travelling carriage from path control deivce 23 also according to the operating result of its processor controls 226, and this downlink service data is stored in downlink service data memory cell 228.Digital transmitter 229 is used for above-mentioned downlink service data is modulated the generation digital signal, the digital signal transition that DAC 261 is used for digital transmitter 229 is produced is an analog signal, simulating transmitting machine 262 is modulated to the analog signal of DAC 261 outputs carrier frequency and carries out power amplification, launches on antenna 263 by duplexer 227 then.Base station control processor 226 is used for storage and carries out base station control method of the present invention (will describe in detail at Fig. 7).
In the wireless communications method of the present invention, by the path control deivce 23 that is connected with movements control center 21 at travelling carriage when first base station in the same base station bunch moves in the second base station scope, itself and communicating to connect of first base station are switched to the second base station mode, realized the backstage switching.Thereby reduced the switching times of travelling carriage, and reduced the call drop probability of travelling carriage.Below transmit and downlink business is transmitted description wireless communications method of the present invention with uplink service.
As shown in Figure 5, be the flow chart of wireless uplink data forwarding.
At first, base station 22 obtains the up configuration information of travelling carriage from path control deivce 23 by its transmitting device 225, and should be stored in downlink business memory cell 228 by up configuration information, above-mentioned up configuration information comprises the information of radio resource allocation that uplink business data is arranged and the code modulation mode (step S51) of uplink business data.
Base station 22 sends to travelling carriage (step S52) by digital transmitter 229, DAC 261, simulating transmitting machine 262, duplexer 227 and antenna 263 with this configuration information on the Radio Resource of system default.
Base station 22 is by the upward signal on the Radio Resource of antenna 263, duplexer 227, analog receiver 224, ADC 223 and the appointment in up configuration information of digital receiver 222 receiving mobiles, and detect this user's wireless signal strength, for example this user's Signal to Interference plus Noise Ratio and signal strength signal intensity (step S53).
The processor controls 226 of base station 22 is according to user's wireless signal strength, judges that measured value is whether less than the threshold value (step S54) of appointment.If measured value less than the appointed threshold value, then finishes repeating process.
If measured value is more than or equal to appointed threshold, then the digital uplink signal of the 22 pairs of travelling carriages in base station is decoded, and obtains final uplink business data, is stored in uplink service memory cell 221 (step S55).
Base station 22 sends the request of transmission by its transmitting device 225 to path control deivce 23, can comprise (the step S56) such as uplink signal strength measurement results of CRC check result, travelling carriage in this request.
Base station 22 judges whether to receive the transmission acknowledge message (step S58) from path control deivce 23.If base station 22 receives the transmission acknowledge message that path control deivce 23 returns, then send the uplink business data of travelling carriage, and be transmitted to movements control center (step S59) to path control deivce 23; Otherwise end repeating process.
Fig. 6 is the path control deivce 23 among Fig. 5 sends a flow chart from acknowledge message (step S57) to selected base station.The transmission that path control deivce 23 receives from base station 22 transmits request message (step S61), and judges the number (step S62) of the base station of request.If the base station number that sends the transmission request message greater than 1, then selects wherein optimum base station to transmit uplink business data (step S63), send acknowledge message (step S64) to above-mentioned optimum base station then; If sending the base station number that transmits request message is 1, then direct execution in step S64.
The method of selection optimum base station (step S63) is as follows: at first, the base station of transmission being transmitted request is made as first set, and the base station that comprises the correct sign of CRC check in the base station with transmission transmission request is made as second and gathers.If second set be empty, then select second gather in the best base station of path control deivce communication quality be optimum base station; If it is optimum base station that second set for empty, is then selected in first set with the top-quality base station of mobile communications.
As shown in Figure 7, be the flow chart of downlink wireless data forwarding.
At first, path control deivce 23 receptions are from the downlink service data (step S71) of movements control center 21.And generating downstream arrangements information according to the characteristic of the character of business and measured wireless channel, this downstream arrangements information contains the information of radio resource allocation that includes downlink service data and the code modulation mode (step S72) of downlink service data.
Then, the wireless channel measurement result that path selector 231 reports according to the base station that is received, select one or more base stations to transmit the downlink service data of travelling carriage, give the transmitting device 233 (step S73) of one or more path control deivces 23 accordingly identical downstream arrangements information and business datum, transmitting device 233 is given base station (step S74) with configuration information and business datum.
Base station 22 receives downstream arrangements information and the downlink service data (step S75) by transmitting device 233 transmissions of path control deivce 23, and by digital transmitter 229, DAC 261, simulating transmitting machine 262, duplexer 227 and antenna 263 configuration information is sent to travelling carriage (step S76) on the Radio Resource of system default.
At last, base station 22 by digital transmitter 229, DAC 261, simulating transmitting machine 262, duplexer 227 and antenna 263 with the downlink service data of travelling carriage according to sending to travelling carriage (step S77) in configuration information specified Radio Resource and prescribed coding modulation system.
Wherein, select the method for base station as follows among the step S73: the optimum base station of at first choosing in the up routing forwarding process is the main separation base station, selects in first set except that the main separation base station uplink signal strength to add a threshold value then and is the inferior base station of selecting greater than the base station of the uplink signal strength of main separation base station.And the downlink service data repeating base station that path selector 231 is selected is above-mentioned main separation base station and the inferior base station of selecting.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
