All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
In this embodiment, a specific process of the terminal location information acquisition method is described from the perspective of a base station, please refer to fig. 1, which shows a flowchart of the terminal location information acquisition method provided in this application, and the method may include the following steps:
step S11: when the base station is started, the base station selects two service channels from the service channels of the base station to be respectively used as a first GPS dedicated channel and a second GPS dedicated channel, and selects one service channel from the available service channels of the base station to be used as the service channel of the terminal.
The time slot of the first GPS dedicated channel is different from the time slot of the second GPS dedicated channel.
In this embodiment, the base station selects one channel from all its own channels as a control channel, and the remaining channels are respectively used as traffic channels.
In this embodiment, since the terminal and the base station communicate according to the DMR standard or the PDT standard, where both the DMR standard and the PDT standard use a 2-slot Time Division Multiplexing (TDM) technique to divide a carrier frequency into two time slots, i.e., one carrier frequency includes two time slots (i.e., channels), and thus the base station is a base station with N carrier frequencies, and the base station includes N × 2 channels, the time slot numbers of the two channels of the same carrier frequency are different, and the time slot numbers of N channels of the N × 2 channels are the same, and the time slot numbers of the other N channels are the same, but the carrier frequencies of the N channels with the same time slot number are different. Such as: the base station is a base station with 4 carrier frequencies, the 4 carrier frequencies are respectively 1 carrier frequency, 2 carrier frequency, 3 carrier frequency and 4 carrier frequencies, the 1 carrier frequency comprises two channels which are respectively a channel a1 and a2, the time slot number of the channel a1 is different from the time slot number of the channel a2, the 2 carrier frequency comprises two channels which are respectively a channel b1 and a channel b2, the time slot number of the channel b1 is different from the time slot number of the channel b2, the 3 carrier frequency comprises two channels which are respectively a channel c1 and a channel c2, the time slot number of the channel c1 is different from the time slot number of the channel c2, the 4 carrier frequency comprises two channels which are respectively a channel d1 and a channel d2, the time slot number of the channel d1 is different from the time slot number of the channel d2, but the time slot numbers of the channel a1, the channel b1, the channel c1 and the channel d 9 are the same, and the time slot numbers of the channel a 695a.
Through the analysis, it can be known that the time slot number of each traffic channel of the base station has only two cases, the time slot number of the first GPS dedicated channel has only two cases, the time slot number of the second GPS dedicated channel has only two cases, and the time slot number of each traffic channel is the same as the time slot number of the first GPS dedicated channel or the time slot number of the second GPS dedicated channel. Such as: the base station comprises 5 service channels which are respectively a service channel 1, a service channel 2, a service channel 3, a service channel 4 and a service channel 5, wherein the time slot number of the service channel 1 is time slot 2, the time slot number of the service channel 2 is time slot 1, the time slot number of the service channel 3 is time slot 2, the time slot number of the service channel 4 is time slot 1, the time slot number of the service channel 5 is time slot 2, the time slot number of the first GPS dedicated channel is time slot 1, and the time slot number of the second GPS dedicated channel is time slot 2. The time slot number of the traffic channel 1 is the same as the time slot number of the second GPS dedicated channel, the time slot number of the traffic channel 2 is the same as the time slot number of the first GPS dedicated channel, the time slot number of the traffic channel 3 is the same as the time slot number of the second GPS dedicated channel, the time slot number of the traffic channel 4 is the same as the time slot number of the first GPS dedicated channel, and the time slot number of the traffic channel 5 is the same as the time slot number of the second GPS dedicated channel.
Step S12: and the base station broadcasts the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel on a control channel, so that the terminal acquires the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel from the control channel.
In this embodiment, the channel information of the first GPS dedicated channel includes at least a channel number and a slot number of the first GPS dedicated channel. The channel information of the second GPS dedicated channel includes at least a channel number and a slot number of the second GPS dedicated channel.
Step S13: the base station sends the same request for inquiring the terminal position information to the first GPS dedicated channel and the second GPS dedicated channel respectively so that the terminal judges whether the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal; if not, monitoring whether a request for inquiring the terminal position information exists in the first GPS dedicated channel; if the terminal exists, the position information of the terminal is uploaded to the base station through the first GPS dedicated channel; if yes, monitoring whether the request for inquiring the terminal position information exists in the second GPS dedicated channel; and if the terminal exists, uploading the position information of the terminal to the base station through the second GPS dedicated channel.
In this embodiment, the base station may periodically issue the same request for querying the location information of the terminal to the first GPS dedicated channel and the second GPS dedicated channel, respectively. Of course, the base station may also issue the same request for querying the location information of the terminal to the first GPS dedicated channel and the second GPS dedicated channel respectively in real time.
In this embodiment, the terminal selects a dedicated GPS channel with a time slot number different from the time slot number of the current service channel of the terminal to monitor, that is, monitors whether a request for querying the location information of the terminal exists in the dedicated GPS channel in a time slot different from the time slot for executing the current service, and uploads the location information of the terminal in a time slot different from the time slot for executing the current service, thereby ensuring that the execution of the service of the terminal itself is not affected.
Because the time slot number of the current service channel of the terminal is only two cases, namely the time slot number of the current service channel of the terminal is the same as the time slot number of the first GPS dedicated channel or the time slot number of the second GPS dedicated channel, on the basis that the time slot number of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal, the time slot number of the second GPS dedicated channel is inevitably different from the time slot number of the current service channel of the terminal, when the time slot number in the channel information of the first GPS dedicated channel is judged to be the same as the time slot number of the current service channel of the terminal, the step of monitoring whether the request for inquiring the terminal position information exists in the second GPS dedicated channel is directly executed.
In this embodiment, the terminal selects a dedicated GPS channel with a time slot number different from the time slot number of the current service channel of the terminal to monitor, that is, monitors whether a request for querying the location information of the terminal exists in the dedicated GPS channel in a time slot different from the time slot for executing the current service, and uploads the location information of the terminal in a time slot different from the time slot for executing the current service, thereby ensuring that the execution of the service of the terminal itself is not affected.
In this embodiment, the terminal, regardless of being in the group call stage, the individual call stage, or the idle period, respectively monitors the first GPS dedicated channel or the second GPS dedicated channel in real time, and once monitoring the terminal location information query request matched with the terminal, uploads the location information of the terminal to the base station.
In the application, because the base station only selects two service channels from the service channels of the base station to be respectively used as the first GPS dedicated channel and the second GPS dedicated channel, the service channels except the two service channels used as the first GPS dedicated channel and the second GPS dedicated channel are all available, compared with a mode that each group calling talk group occupies two channels, the occupancy rate of the service channels of the base station is reduced, the number of the service channels available to the base station is increased, and therefore the utilization rate of the service channels of the base station is improved.
Furthermore, no matter the terminal initiates the single call service request or the group call service request, the terminal in the single call service or the terminal in the group call service can monitor the corresponding request for inquiring the terminal location information through two fixed GPS dedicated channels (i.e. the first GPS dedicated channel and the second GPS dedicated channel) to realize uploading of the location information, so that the base station can acquire the location information of the terminal in the single call service and the location information of the terminal in the group call service.
In this embodiment, the process of the base station selecting two traffic channels from its own traffic channels as the first GPS dedicated channel and the second GPS dedicated channel includes:
the base station selects two service channels with the same carrier frequency and different time slot numbers from the service channels of the base station, and the two service channels are respectively used as a first GPS dedicated channel and a second GPS dedicated channel;
or, the base station selects two service channels with different carrier frequencies and different time slot numbers from the service channels of the base station, and the two service channels are respectively used as a first GPS dedicated channel and a second GPS dedicated channel.
In this embodiment, another method for acquiring location information of a terminal is extended based on the method for acquiring location information of a terminal shown in fig. 1, and referring to fig. 2, after the base station broadcasts the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel on a control channel, the method further includes:
step S21: and the base station issues a GPS special channel activation command to the control channel.
And the base station issues a GPS dedicated channel activation command to the control channel so that the terminal receives the GPS dedicated channel activation command from the control channel after acquiring the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel from the control channel to prepare for executing the step that the terminal judges whether the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal.
Example two

step S31: and the terminal acquires the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel broadcasted by the base station from the control channel.
Step S32: and the terminal judges whether the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal.

and judging whether the terminal address carried in the request for inquiring the terminal position information is matched with the address of the terminal.
If the judgment result is that the terminal address carried in the request for inquiring the terminal position information is matched with the address of the terminal, the terminal position information is uploaded through the first GPS dedicated channel before the terminal position information is uploaded to the base station or through the second GPS dedicated channel.
And if the judgment result is that the terminal address carried in the terminal position information inquiry request is not matched with the address of the terminal, not uploading the position information of the terminal to the base station.

Of course, the base station may also issue the same request for querying the location information of the terminal to the first GPS dedicated channel and the second GPS dedicated channel respectively in real time.
Step S45: and the terminal judges whether the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal.
If not, go to step S46, and if so, go to step S48.
Step S46: and monitoring whether a request for inquiring the terminal position information exists in the first GPS dedicated channel.
If yes, go to step S47, and if not, continue to monitor whether there is a request for querying terminal location information in the first GPS dedicated channel.
Step S47: and uploading the position information of the terminal to the base station through the first GPS dedicated channel.
In this embodiment, the terminal selects a dedicated GPS channel with a time slot number different from the time slot number of the current service channel of the terminal to monitor, that is, monitors whether a request for querying the location information of the terminal exists in the dedicated GPS channel in a time slot different from the time slot for executing the current service, and uploads the location information of the terminal in a time slot different from the time slot for executing the current service, thereby ensuring that the execution of the service of the terminal itself is not affected.
Step S48: and monitoring whether the request for inquiring the terminal position information exists in the second GPS dedicated channel.
If not, go to step S49.
Since the time slot number of the current traffic channel of the terminal is only two cases, that is, the time slot number of the current traffic channel of the terminal is the same as the time slot number of the first GPS dedicated channel or the time slot number of the second GPS dedicated channel, the time slot number of the second GPS dedicated channel is inevitably different from the time slot number of the current traffic channel of the terminal on the basis that the time slot number of the first GPS dedicated channel is the same as the time slot number of the current traffic channel of the terminal, and thus, when it is determined that the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current traffic channel of the terminal, the step S18 is directly executed.
Step S49: and uploading the position information of the terminal to the base station through the second GPS dedicated channel.
In this embodiment, the terminal selects a dedicated GPS channel with a time slot number different from the time slot number of the current service channel of the terminal to monitor, that is, monitors whether a request for querying the location information of the terminal exists in the dedicated GPS channel in a time slot different from the time slot for executing the current service, and uploads the location information of the terminal in a time slot different from the time slot for executing the current service, thereby ensuring that the execution of the service of the terminal itself is not affected.
In this embodiment, the terminal, regardless of being in the group call stage, the individual call stage, or the idle period, respectively monitors the first GPS dedicated channel or the second GPS dedicated channel in real time, and once monitoring the terminal location information query request matched with the terminal, uploads the location information of the terminal to the base station.
In the application, because the base station only selects two service channels from the service channels of the base station to be respectively used as the first GPS dedicated channel and the second GPS dedicated channel, the service channels except the two service channels used as the first GPS dedicated channel and the second GPS dedicated channel are all available, compared with a mode that each group calling talk group occupies two channels, the occupancy rate of the service channels of the base station is reduced, the number of the service channels available to the base station is increased, and therefore the utilization rate of the service channels of the base station is improved.
Furthermore, no matter the terminal initiates the single call service request or the group call service request, the terminal in the single call service or the terminal in the group call service can monitor the corresponding request for inquiring the terminal location information through two fixed GPS dedicated channels (i.e. the first GPS dedicated channel and the second GPS dedicated channel) to realize uploading of the location information, so that the base station can acquire the location information of the terminal in the single call service and the location information of the terminal in the group call service.
For example, please refer to fig. 5, for example, as shown in fig. 5, BS GPS CH1 is a first GPS dedicated channel, BS GPS CH2 is a second GPS dedicated channel, BS GPS CH1 has a time slot number of 2, BS GPS CH2 has a time slot number of 1, BS Voice CH1 is a first traffic channel, BS Voice CH2 is a second traffic channel, BS Voice CH1 has a time slot number of 1, BS Voice CH2 has a time slot number of 2, the terminal allocated on BS Voice CH1 monitors BS GPS CH1 in real time, and when it is monitored that there is a request for inquiring terminal location information in BS CH1, the terminal uploads the location information of the terminal at the next time slot of BSGPS CH1 or at a time slot after the next time slot (i.e. GPS in fig. 2). The terminal allocated on the BS Voice CH2 listens to the BS GPS CH2 in real time, and when it is monitored that there is a request for inquiring the terminal location information from the BS GPS CH2, the terminal will upload the location information of the terminal (i.e., GPS in fig. 5) at the next time slot or a time slot after the next time slot of the BS GPS CH 2.
In this embodiment, another terminal location information collecting method is extended on the basis of the terminal location information collecting method shown in fig. 4, please refer to fig. 6, which may include the following steps:
step S61: when the base station is started, the base station selects two service channels from the service channels of the base station to be respectively used as a first GPS dedicated channel and a second GPS dedicated channel, and selects one service channel from the available service channels of the base station to be used as the service channel of the terminal.
The time slot of the first GPS dedicated channel is different from the time slot of the second GPS dedicated channel.
Step S62: and the base station broadcasts the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel on a control channel.
Steps S61 and S62 are the same as steps S41 and S42 in the terminal position information collecting method shown in fig. 4, and are not described again here.
Step S63: and the base station issues a GPS special channel activation command to the control channel.
In this embodiment, the base station issues a GPS dedicated channel activation command to the control channel to notify the terminal that it can start listening to the GPS dedicated channel.
Certainly, the base station may not issue the GPS dedicated channel activation command to the control channel, and start monitoring the GPS dedicated channel by default after the terminal is powered on.
Step S64: and the terminal acquires the channel information of the first GPS dedicated channel and the channel information of the second GPS dedicated channel from the control channel.
Step S64 is the same as step S43 in the terminal position information collection method shown in fig. 4, and is not described again here.
Step S65: and the terminal receives the GPS dedicated channel activation command from the control channel so as to prepare for executing the step that the terminal judges whether the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal.
Step S66: and the base station respectively issues the same terminal position information inquiry request to the first GPS dedicated channel and the second GPS dedicated channel.
Step S67: and the terminal judges whether the time slot number in the channel information of the first GPS dedicated channel is the same as the time slot number of the current service channel of the terminal.
If not, step S68 is executed, and if yes, step S610 is executed.
Step S68: and monitoring whether a request for inquiring the terminal position information exists in the first GPS dedicated channel.
If yes, go to step S69, and if not, continue to monitor whether there is a request for querying terminal location information in the first GPS dedicated channel.
Step S69: and uploading the position information of the terminal to the base station through the first GPS dedicated channel.
