Referring to fig. 1, a first aspect of the present invention discloses a method for switching a multi-mode base station-to-network communication, including the following steps:
step 101: a first terminal in a digital trunking communication system sends an uplink activation instruction to a first base station, and the first base station sends downlink broadcast according to the uplink activation instruction;
step 102: the first terminal confirms that the first base station is successfully activated, the first terminal sets a first radio frequency point and a first transmission time slot, service data are sent to the first base station based on the first radio frequency point and the first transmission time slot, the first base station sets a first service channel after receiving the service data, and the service data are sent to a second base station through the first service channel;
step 103: and after receiving the service data, the second base station sets a second service channel, sends the service data to other terminals belonging to the second base station through the second service channel, and after receiving the signaling for establishing the call, the other terminals of the second base station enter the call service to realize interconnection and intercommunication among the terminals of the cross base stations.
In step 101, each first bs has a plurality of carriers, for example, 2 carriers, carrier 1 and carrier 2, and the number of available traffic channels is equal to the number of carriers × the number of timeslots is 4, which are CH1, CH2, CH3 and CH4, respectively. Each carrier of the base station is configured with an operating frequency, which is BS _ F1 and BS _ F2, and a common frequency BS _ Fc. After the base station is powered on, the base station is in a silent state, and during the silent state, the receiving frequency of the carrier 1 keeps frequency scanning taking the working frequency BS _ Rx _ F1 and the public frequency BS _ Rx _ Fc as a list, and waits for the signal forwarding terminal to initiate activation.
Referring to fig. 2, optionally, in an embodiment of step 101, the sending, by the first terminal in the digital trunking communication system, the uplink activation instruction to the first base station includes: when the first terminal belongs to the first base station, the first terminal sends an uplink activation instruction to the base station by using the common frequency MS _ Tx _ Fc, and simultaneously sets the carrier receiving frequency to be the working frequency BS _ Rx _ F1.
Optionally, in this embodiment, the terminals belonging to the first base station are collectively referred to as first terminals, and for convenience of distinguishing, all the first terminals are classified and identified as MS1 and MS2, and a carrier 1 operating frequency F1, a frequency point number of 59, a carrier 2 operating frequency F2, a frequency point number of 72, a common frequency Fc, and a frequency point number of 1 are set. MS1, the home frequency point of MS2 is 59, before MS1 initiates service, the activation signal of uplink common frequency point 1 is sent first, after the first base station is activated, the downlink broadcast of common frequency point 1 is sent first for a period of time. Both MS1 and MS2 received the downlink broadcast (carrying frequency point 59/72, frequency point number 2), and write 59 and 72 into the local scan queue. Then the MS1 receives the signaling synchronization of the downlink 59 frequency point of the base station, and confirms that the activation of the first base station is successful.
Referring to fig. 3, optionally, in another embodiment of step 101, when the first terminal does not belong to the first base station, the first terminal sends an uplink activation instruction to the first base station using the common frequency MS _ Tx _ Fc, after receiving the uplink activation instruction, the first base station sends downlink broadcasts for several times using the common frequency BS _ Tx _ Fc, and the first terminal obtains operating frequency information of the first base station from the downlink broadcasts and sets an uplink transmission frequency between the first terminal and the first base station.
Similarly, the carrier 1 operating frequency F1 of the first terminal is set, the frequency point number is 21, the carrier 2 operating frequency F2 is set, the frequency point number is 113, the common frequency Fc is set, and the frequency point number is 1. The home frequency point of MS1 and MS2 is 59, before MS1 initiates service, an uplink activation signal with a common frequency point of 1 is sent first, and after the first base station is activated, downlink broadcast with a common frequency point of 1 is sent for a period of time. After receiving the downlink broadcast (the frequency point carried is 21/113), MS1 and MS2 write 21 and 113 into the local scanning queue, and then MS1 receives the signaling synchronization of the downlink 21 frequency point of the base station, and confirms that the activation is successful.
Referring to fig. 4, optionally, in an embodiment of step 102, after the terminal MS1 activates the first base station BS1, the transmission frequency point is set to 59, the transmission time slot is set to 1, and the call service with the group number of 10901 is initiated. After receiving the call, the base station BS1 encapsulates the data, forwards the IP data packet to the base station BS2, and simultaneously allocates the frequency point 59 and the time slot 1 as traffic channels and allocates the frequency point 59 and the time slot 2 as new control channels. Then, the base station BS1 forwards the group number 10901 call voice service on the frequency point 59 and the timeslot 1, and the information carried by the LC signaling and EMS includes: the new control channel frequency point number is 59 and the control channel time slot number is 2;
sending a broadcast signaling on a frequency point 59 and a time slot 2, wherein the carried information comprises: the working frequency point information (59/72), the new control channel carrier number is 1 and the control channel time slot number is 2.
Optionally, in step 103, after receiving the networking call service, the second base station BS2 does not forward the IP data packet to other base stations, and allocates the frequency point 21 and the time slot 1 as service channels, and allocates the frequency point 21 and the time slot 2 as new control channels. Then, the second base station BS2 forwards the group number 10901 call voice service on frequency point 21 and timeslot 1, where the information carried by the LC signaling and EMS includes: the new control channel frequency point number is 21 and the control channel time slot number is 2; sending a broadcast signaling on a frequency point 21 and a time slot 2, wherein the carried information comprises: the working frequency point information (21/113), the new control channel carrier number is 1 and the control channel time slot number is 2. After receiving the signaling for establishing the call, the terminal MS3 enters the call service to implement interconnection and interworking between terminals across base stations.
In some embodiments of the present invention, since the receiving frequency is in the scanning state when the relay base station is silent, the activation signal of the terminal may be missed. In order to improve the success rate of activation, an activation mode of a signal transfer system is designed, namely when a signal transfer terminal sends activation, a plurality of uplink DMR signaling synchronous codes are arranged in one time slot, and a plurality of time slots are kept to be sent; the signal transfer base station adopts a radio frequency component for fast scanning, and can fast capture the synchronous code. After finding the signaling synchronous code, the base station is converted into an active state.
Optionally, in other embodiments of the present invention, the relaying terminal may start to keep the periodic frequency scanning with MS _ Rx _ Fc and MS _ Rx _ F1 as a scanning list. Assuming that the base station already forwards the service before the terminal initiates activation, the terminal may search for downlink voice synchronization or signaling synchronization of the base station, stop scanning, and decode service data. And if the terminal service layer finds that the service data meets the access rule, starting to receive the current service.
The second aspect of the invention discloses a multi-mode base station relay communication networking system, which is applied to mobile terminals and base stations, wherein a plurality of mobile terminals belong to one base station, and the mobile terminals at least realize communication with one corresponding base station.
The third aspect of the invention discloses a computer device, comprising a memory and a processor, wherein the memory stores a multi-mode base station relay communication networking system, and the processor implements the following steps when executing the multi-mode base station relay communication networking system:
step 101: a first terminal in a digital trunking communication system sends an uplink activation instruction to a first base station, and the first base station sends downlink broadcast according to the uplink activation instruction;
step 102: the first terminal confirms that the first base station is successfully activated, the first terminal sets a first radio frequency point and a first transmission time slot, service data are sent to the first base station based on the first radio frequency point and the first transmission time slot, the first base station sets a first service channel after receiving the service data, and the service data are sent to a second base station through the first service channel;
step 103: and after receiving the service data, the second base station sets a second service channel, sends the service data to other terminals belonging to the second base station through the second service channel, and after receiving the signaling for establishing the call, the other terminals of the second base station enter the call service to realize interconnection and intercommunication among the terminals of the cross base stations.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
