Background
In practical application, in order to realize mutual communication between terminal devices in different trunking systems, interconnection between terminal devices in different trunking systems needs to be realized.

Another available way is that the terminal device directly accesses the cluster system through a general registration mechanism. Although this method is commonly used, for the transceiver in the terminal device, one transceiver can only monitor one data channel corresponding to one terminal device, so as to implement one-way data access, and the transceiver has low working efficiency. When the systems are interconnected, a large number of terminal devices are accessed into the system and perform data access, transceivers with the number equivalent to that of the terminal devices are required to participate in communication, and the transceiver overhead is large.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
The embodiment of the invention discloses a data transmission method, which is applied to a transceiver, wherein the transceiver monitors a control channel and all data channels on a set main carrier;
in particular, a transceiver operates at a set carrier frequency, referred to as the primary carrier of the transceiver. Generally, the primary carrier will be divided into a plurality of channels according to time, for example, in a trunking communication system, the primary carrier of the transceiver of the terminal device may be divided into four time slots, each time slot being used as a channel, specifically including a control channel, and three data channels.
In the prior art, a transceiver only monitors a data channel and a control channel on a primary carrier, and therefore only data access of the monitored data channel is possible. Other data channels on the primary carrier are monitored by other transceivers.
In the embodiment of the present invention, as shown in fig. 1, the transceiver listens to all channels on the primary carrier, including the control channel and the three data channels (voice channels). Each channel is occupied by a set number of terminals. That is, in the embodiment of the present invention, the control channel and the data channel on the primary carrier carry the service data of a set number of terminals. The terminals with the set number flexibly occupy each channel on the main carrier in a time division multiple access mode. Specifically, when the base station needs to communicate with the terminal, the base station sends a control signaling to the terminal through a control channel, allocates an available data channel for the terminal, and switches the terminal to the data channel allocated by the base station, i.e., the terminal can occupy the data channel to perform data communication with the base station. And when the terminal transmits data to the base station, the terminal selects an idle data channel to transmit the data.
It should be noted that the transceiver includes a pair of transceiver devices, which respectively and simultaneously operate at the uplink and downlink frequency points of the main carrier.
Referring to fig. 2, a data transmission method according to an embodiment of the present invention includes:
s201, receiving data sent by a base station through any data channel in all the data channels;
specifically, the transceiver applying the technical scheme of the embodiment of the invention works on 4 time slots of the set main carrier, thereby realizing the monitoring of any data channel of the set main carrier. When the base station sends data to the terminal through any time slot of the main carrier, specifically, through any data channel on the main carrier, the transceiver can receive the data, and the data reception on all monitored data channels is realized.
S202, analyzing and confirming a terminal corresponding to the data and a data channel occupied by the terminal corresponding to the data according to the data;
specifically, in the embodiment of the present invention, a set number of terminals flexibly occupy each channel on the primary carrier in a time division multiple access manner, so that there is no one-to-one correspondence between the terminals and the data channels. Data sent by the base station to the terminal must be transmitted through a channel occupied by the base station, and can be successfully received by the terminal. Therefore, when the transceiver receives the data sent to the terminal by the base station through any monitored data channel, the transceiver firstly analyzes and confirms the terminal corresponding to the data and the data channel occupied by the corresponding terminal through the data information.
It should be noted that the data channel occupied by the terminal corresponding to the data received by the transceiver and the data channel for receiving the data by the transceiver may be the same data channel or different data channels.
S203, sending the data to the terminal corresponding to the data through the data channel occupied by the terminal corresponding to the data.
Specifically, after confirming the terminal corresponding to the received data and the data channel occupied by the terminal corresponding to the data, the transceiver transmits the data to the data channel, that is, transmits the data to the terminal corresponding to the data through the data channel.
The data transmission method provided by the embodiment of the invention is applied to a transceiver, and the transceiver monitors a control channel and all data channels on a set main carrier; the method comprises the following steps: receiving data transmitted by the base station through any data channel in all the data channels; analyzing and confirming a terminal corresponding to the data and a data channel occupied by the terminal corresponding to the data according to the data; and sending the data to the terminal corresponding to the data through the data channel occupied by the terminal corresponding to the data. By adopting the technical scheme provided by the invention, the transceiver monitors a plurality of data channels and can complete data transmission in any monitored data channel, the working efficiency is higher, and the transceiver is applied to system interconnection, so that the transceiver overhead can be reduced.
Optionally, in another embodiment of the present invention, the method further includes:
and receiving the data sent by the terminal through any data channel in all the data channels, and sending the data to the base station.
Specifically, corresponding to the downlink communication method disclosed in the foregoing embodiment, the data transmission method provided in the embodiment of the present invention also includes an uplink communication method. In the uplink communication, the transceiver receives data transmitted by the terminal through an arbitrary data channel and then transmits the received data to the base station.
It should be noted that, in the uplink communication process, the transceiver can send the data sent by the terminal to the base station through any one data channel, so from the purpose of simplification, after the terminal sends the data to the transceiver through the data channel occupied by the terminal, the transceiver directly sends the data to the base station through the data channel occupied by the terminal.
Optionally, in another embodiment of the present invention, referring to fig. 3, the method further includes:
s301, receiving a control signaling sent by a base station through the control channel;
specifically, only one control channel is used for the base station to send the control signaling on one primary carrier, and therefore, the control signaling of all the terminals operating on the primary carrier is sent through the one control channel. Accordingly, it is possible for the transceiver to receive control signaling over the control channel, which may be control signaling sent by the base station to any one of the terminals operating on the primary carrier.
S302, analyzing the control signaling and confirming a terminal corresponding to the control signaling;
specifically, the transceiver analyzes the received control signaling to determine the terminal corresponding to the control signaling, that is, to determine to which terminal the base station is to send the control signaling.
S303, the control signaling is sent to the terminal corresponding to the control signaling through the control channel.
Specifically, after confirming the destination terminal of the control signaling, the transceiver sends the control signaling to the corresponding destination terminal through the control channel.

The embodiment of the invention also discloses a communication terminal, which is shown in fig. 6 and comprises:
a communication unit 601 and a processing unit 602;
the communication unit 601 is connected to the processing unit 602, and configured to monitor a control channel and all data channels on a set primary carrier, and perform data transceiving operation;
specifically, the communication unit 601 and the processing unit 602 included in the communication terminal in this embodiment are respectively configured to execute operations related to a physical layer and an application layer. The communication unit 601 is configured to perform data transceiving operations to implement a communication link connection between the terminal device and the base station. Specifically, the communication unit 601 may be a transceiver in a communication terminal in terms of hardware implementation.
It should be emphasized that, in the existing communication terminal, the apparatus for performing data transceiving operation to realize communication between the terminal device and the base station only works on one data channel, i.e. only monitors one data channel to realize one data access. That is, the communication device of the communication terminal in the prior art is only used for solving the communication problem of the terminal, and does not monitor other data channels of the main carrier where the communication terminal is located. In the communication terminal according to the embodiment of the present invention, the communication unit 601 monitors the control channel and all the data channels on the set primary carrier. For example, referring to fig. 1, assuming that a main carrier of a certain trunking communication system includes 4 channels, which include 1 control channel and 3 data channels (voice channels), in the prior art, a communication device of a terminal only monitors one data channel (voice channel), whereas in the embodiment of the present invention, a communication unit 601 monitors the control channel on the main carrier and the 3 data channels (voice channels), and can perform data transceiving operations of the respective channels respectively.
That is, the communication unit 601 listens to all channels on the host carrier, including the control channel and all data channels, and can simultaneously implement data transmission and reception for all channels. Obviously, the communication unit 601 in the embodiment of the present invention has the capability of multiple concurrent communications, and can monitor all channels on the located main carrier, and perform data transceiving operations respectively, thereby significantly improving the working efficiency of the communication unit 601 of the communication terminal.
A processing unit 602, configured to control a set number of terminal devices to occupy a control channel and all data channels on the set primary carrier; the set number of terminal devices comprise entity terminal devices and/or simulation terminal devices.
Specifically, in the embodiment of the present invention, the processing unit 602 further configured to set the communication terminal to control a set number of terminal devices to occupy all channels, including a control channel and all data channels, on the main carrier occupied by the communication terminal. In a trunking communication system, particularly when cross-system communication is involved, the number of terminal devices participating in communication is large, but the number of terminals performing real-time communication is not large. Based on the system characteristics, the embodiment of the present invention sets a set number of terminal devices to occupy the control channel and all data channels on the primary carrier, occupies the idle data channel when the terminal devices need to perform data communication, and releases the data channel after the communication is finished, where the data channel can be occupied by other terminal devices.
Through the above arrangement, in the communication terminal according to the embodiment of the present invention, the communication unit 601 monitors all channels on the main carrier where the terminal device is located, and meanwhile, the processing unit 602 controls a set number of terminal devices to occupy all channels on the main carrier where the terminal device is located. The communication unit 601 and the processing unit 602 work cooperatively, so that data communication of a set number of terminal devices can be realized by using one communication unit 601, and the working efficiency of the communication device of the communication terminal is improved as a whole. In a trunking communication system with a large number of communication terminals or an interconnected trunking communication system, each communication terminal does not necessarily occupy one data channel, and the system throughput is improved on the premise of the same channel resources and the same number of communication units 601.
It should be noted that, in the embodiment of the present invention, the configuration processing unit 602 controls a set number of terminal devices to occupy a control channel and all data channels on the main carrier. The terminal devices with the set number may include physical terminal devices or analog terminal devices. The simulated terminal device may be obtained by simulation of the processing unit 602, or by simulation of set software, and may be used for receiving mapping communication of a terminal device outside the system when the cluster systems are interconnected.
The communication terminal provided by the embodiment of the invention comprises a communication unit 601 and a processing unit 602; the communication unit 601 is connected to the processing unit 602, and configured to monitor a control channel and all data channels on a set primary carrier, and perform data transceiving operation; a processing unit 602, configured to control a set number of terminal devices to occupy a control channel and all data channels on the set primary carrier; the set number of terminal devices comprise entity terminal devices and/or simulation terminal devices. By adopting the communication terminal provided by the embodiment of the invention, the monitoring on all channels of the main carrier is realized by utilizing the communication unit 601, meanwhile, the processing unit 602 controls the terminal equipment with set quantity to occupy all channels on the main carrier, the communication unit 601 and the processing unit 602 work cooperatively, the communication unit 601 of one communication terminal can process the data communication of a plurality of terminal equipment, the working efficiency of the communication unit 601 is higher, and especially in system interconnection, the quantity of the terminals which can be accessed into the system can be greatly increased.
Optionally, in another embodiment of the present invention, when the processing unit 602 controls a set number of terminal devices to occupy a control channel and all data channels on the set primary carrier, specifically, the processing unit is configured to:
and controlling the terminal equipment with the set number to occupy the control channel and all the data channels on the set main carrier wave in a time division multiple access mode.
Specifically, as shown in fig. 1, a main carrier where a communication terminal is located is divided into a control channel and a data channel (voice channel) according to a time slot, and different channels have corresponding time slot identifiers. Based on the above principle, when different terminal devices occupy different channels to transmit data signals, the terminal signals from different addresses can be distinguished according to the time slot, i.e. the system performs data communication in a time division multiple access manner.
It should be noted that, because the terminal device and the data channel do not have a one-to-one correspondence, and the terminal device occupies the data channel temporarily, in the embodiment of the present invention, one data channel, that is, one timeslot does not correspond to a terminal device with a fixed address, but dynamically changes according to the communication requirement of the terminal device.
The embodiment of the invention also discloses another communication terminal, which is shown in fig. 7 and comprises the following components:
a memory 701, a transceiver 702, and a processor 703;
the memory 701 is connected to the transceiver 702 and the processor 703, and is used for storing programs and data generated during the program running process;
the transceiver 702 is connected to the processor 703 and is configured to execute the program stored in the memory to implement the following functions:
monitoring a control channel and all data channels on a set main carrier, and executing data transceiving operation;
specifically, the transceiver 702 specifically includes a pair of transceiver devices, which respectively operate at uplink and downlink frequency points on the main carrier where the transceiver device is located. The transceiver monitors each channel on the main carrier, including the control channel and all data channels.
When the communication terminal supports multi-carrier communication, transceivers with the same number as the number of carriers need to be arranged in the communication terminal, and the transceivers operate on each carrier frequency respectively to realize data communication on each carrier frequency. Accordingly, only the first time slot of the carrier in which one transceiver is located is used as a control channel in the plurality of transceivers, and each time slot of the carrier in which the other transceiver is located is used as a data channel.
The processor 703 is configured to implement the following functions by executing the program stored in the memory 701:
controlling a set number of terminal devices to occupy control channels and all data channels on the set main carrier; the set number of terminal devices comprise entity terminal devices and/or simulation terminal devices.
Specifically, the processor 703 controls a set number of terminal devices to occupy all channels, including a control channel and all data channels, on the main carrier occupied by the communication terminal. In a trunking communication system, particularly when cross-system communication is involved, the number of terminal devices participating in communication is large, but the number of terminals performing real-time communication is not large. Based on the system characteristics, the embodiment of the present invention sets a set number of terminal devices to occupy the control channel and all data channels on the primary carrier, occupies the idle data channel when the terminal devices need to perform data communication, and releases the data channel after the communication is finished, where the data channel can be occupied by other terminal devices.
It should be noted that, in the embodiment of the present invention, the setting processor 703 controls a set number of terminal devices to occupy a control channel and all data channels on the main carrier where the terminal devices are located. The terminal devices with the set number may include physical terminal devices or analog terminal devices. The simulated terminal device may be simulated by the processor 703 or by set software, and may be used to receive mapping communication of the terminal device outside the system when the cluster systems are interconnected.
With the above arrangement, in the communication terminal according to the embodiment of the present invention, the transceiver 702 monitors all channels on the main carrier, and meanwhile, the processor 703 controls a set number of terminal devices to occupy all channels on the main carrier. The transceiver 702 and the processor 703 cooperate with each other to realize data communication of a set number of terminal devices by using one transceiver 702, thereby improving the working efficiency of the communication apparatus of the communication terminal as a whole. In a trunking communication system or an interconnected trunking communication system with a large number of communication terminals, each communication terminal does not necessarily occupy one data channel, and system throughput is improved on the premise of the same channel resources and the same number of transceivers 702.
Optionally, in another embodiment of the present invention, when the processor 703 controls a set number of terminal devices to occupy the control channel and all data channels on the set primary carrier, the processor is specifically configured to:
and controlling the terminal equipment with the set number to occupy the control channel and all the data channels on the set main carrier wave in a time division multiple access mode.
Specifically, as shown in fig. 1, a main carrier where a communication terminal is located is divided into a control channel and a data channel (voice channel) according to a time slot, and different channels have corresponding time slot identifiers. Based on the above principle, when different terminal devices occupy different channels to transmit data signals, the terminal signals from different addresses can be distinguished according to the time slot, i.e. the system performs data communication in a time division multiple access manner.
It should be noted that, because the terminal device and the data channel do not have a one-to-one correspondence, and the terminal device occupies the data channel temporarily, in the embodiment of the present invention, one data channel, that is, one timeslot does not correspond to a terminal device with a fixed address, but dynamically changes according to the communication requirement of the terminal device.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
