Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a terminal device. Background Technology

[0002] In drive-testing equipment for terrestrial mobile communication networks, due to the small size and low power consumption of antenna components, the communication component and carrier monitoring component are typically equipped with independent antennas. These are independent terminal units that independently perform drive-testing tasks. The drive-testing equipment industry for related communication satellite systems started later and has largely adopted the system architecture of drive-testing equipment for terrestrial mobile communication systems.

[0003] For ground users of broadband communication satellite systems, antenna assemblies are typically large-aperture parabolic antennas or phased array antennas, with individual antennas measuring on the order of meters and consuming power ranging from tens to hundreds of watts. Configuring separate antenna assemblies for the communication and carrier monitoring components results in bulky and power-hungry drive-test equipment, and also increases the workload for antenna installation, deployment, calibration, and debugging during equipment deployment.

[0004] It should be noted that the statements herein provide background information in connection with this disclosure only and do not necessarily constitute prior art. Utility Model Content

[0005] In view of the above problems, a terminal device is proposed to overcome or at least partially solve the above problems.

[0008] The above-described at least one technical solution adopted in the exemplary embodiment can achieve the following beneficial effects:

[0009] In an exemplary embodiment of this disclosure, the communication component and the carrier monitoring component share the same antenna component.

[0031] As used herein, the term "satellite network device" refers to a node located on a satellite or ground segment within a satellite communication network. Terminal devices access the network and receive services through this node. Depending on the terminology and technology applied, a satellite network device can refer to a base station (BS) or access point (AP) that serves as a satellite payload, such as a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), an NR NB (also known as a gNB), a Remote Radio Unit (RRU), a Radio Header (RH), a Remote Radio Header (RRH), or a relay node.

Examples of these functions include boot server functions and / or home subscriber servers, which may be implemented in the user equipment device by providing the user equipment device with software configured to cause the user equipment device to perform from the perspective of these functions / nodes.

[0034] In related technical solutions, the ground user antenna components of broadband communication satellite systems are typically large-aperture parabolic antennas or phased array antennas, with individual antennas measuring in the meter range and power consumption ranging from tens to hundreds of watts. The communication components and carrier monitoring components are configured with independent antenna components, resulting in large overall size and high power consumption of the drive-test equipment. This places high demands on the equipment deployment site or vehicle, as well as power supply requirements, and the deployment process involves a significant workload for antenna installation, placement, calibration, and debugging.

[0035] In terminal equipment, the communication component and carrier monitoring component independently perform drive test tasks through different antenna components. The carrier monitoring component cannot simultaneously perform real-time evaluation and analysis of the wireless link signal propagation quality carrying communication services during the communication drive test process. Network optimization personnel need to perform post-processing such as comparison and synthesis of the asynchronously collected data from the communication component and carrier monitoring component to pinpoint service experience issues caused by wireless signal propagation quality. Because the carrier monitoring component lacks network access capabilities and only supports signal quality monitoring and analysis of downlink common channels such as synchronization channels and broadcast channels, it cannot monitor and evaluate the signal quality of downlink service channels based on network scheduling.

[0036] To address the shortcomings of existing wireless communication terminal equipment's integrated communication and carrier monitoring components, a more universal terminal equipment is designed. In this terminal equipment, the communication and carrier monitoring components share the same antenna component, which is reused under the control of the main control component.

[0037] The technical solutions provided by the embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0038] The disclosed embodiments provide a terminal device 100. For example... Figure 1The diagram shows a schematic representation of a terminal device 100 in this embodiment. The terminal device 100 includes an antenna assembly 101, a splitter / switching assembly 102, and a device assembly. The device assembly includes at least a communication assembly 103 and a carrier monitoring assembly 104. The communication assembly 103 and the carrier monitoring assembly 104 are connected to the same antenna assembly 101 via the splitter / switching assembly 102. The connections between the components, based on their externally presented functional interfaces, include, but are not limited to, the following: signal line connection, clock line connection, transmission line connection, serial port connection, and network line connection.

[0039] It is understandable that when a terminal device is used as a drive test device, since it is connected to the same set of antenna components, the communication component and the carrier monitoring component can independently carry out drive test tasks in different time periods when they are scheduled. After the communication component controls the antenna component to enter the network, the carrier monitoring component can synchronously listen to the downlink signal received by the antenna component and synchronously monitor the propagation quality of the wireless air interface downlink signal of the real-time communication service.

[0040] In some instances, the splitter switching component 102 includes an uplink transmit channel and a downlink receive channel, the uplink transmit channel connecting the antenna assembly 101 to the communication component 103, and the downlink receive channel connecting the antenna assembly 101 to the communication component 103 and the carrier monitoring component 104.

[0041] Depend on Figure 1 It can be seen that the splitter switching component 102 connects the transceiver interface of the antenna component to the corresponding transceiver interfaces of the communication component 103 and the carrier monitoring component 104 through the internally configured uplink transmission channel and downlink reception channel, so as to realize the transmission of uplink and downlink signals.

[0042] It is understandable that the uplink transmission channel and the downlink reception channel can transmit communication air interface signals, and realize information interaction between the drive test equipment and the base station equipment or satellite equipment through the communication air interface signals.

[0043] In some embodiments, a power divider 1022 is provided in the downlink receiving channel. The input port of the power divider is connected to the receiving module 1012 of the antenna assembly, and the two output ports of the power divider are respectively connected to the receiving module 1032 of the communication assembly and the receiving module 1041 of the carrier monitoring assembly. Two low-noise amplifiers 1025 are also provided in the downlink receiving channel. The two output ports of the power divider are respectively connected to the receiving module 1032 of the communication assembly and the receiving module 1041 of the carrier monitoring assembly via the two low-noise amplifiers 1025. A power amplifier 1021 is provided in the uplink transmitting channel. The input port of the power amplifier is connected to the transmitting module 1031 of the communication assembly, and the output port of the power amplifier is connected to the transmitting module 1011 of the antenna assembly.

[0044] It is understandable that setting a power amplifier in the uplink transmission channel of the splitter improves the signal quality of the uplink signal and enhances the communication effect; setting a power divider in the downlink receiving channel of the splitter can split the downlink signal into multiple paths and connect them to multiple receiving devices. At the same time, setting a low-noise amplifier on each branch of the power divider can compensate for the attenuation of the downlink signal and improve the communication effect.

[0045] In some embodiments, the device components further include a main control component 105, and the splitter switching component includes an Ethernet transmission channel that connects the antenna component 101 to the communication component 103, the carrier monitoring component 104, and the main control component 105. The Ethernet transmission channel is equipped with a routing switching matrix, i.e., a LAN switching matrix 1024. A first port of the routing switching matrix is ​​connected to the antenna control module 1014 of the antenna component, and a second port of the routing switching matrix is ​​connected to the network module of the communication component, i.e., the communication component management LAN module 1034, the network module of the carrier monitoring component, i.e., the carrier monitoring component LAN module 1043, and the network module of the main control component, i.e., the main control component LAN module 1051.

[0046] It is understandable that the split-circuit interaction component, through the set LAN switching matrix, enables the transmission of data between the communication component, carrier monitoring component, and antenna component, including but not limited to RF frequency points, polarization direction, power amplification / attenuation coefficients, servo program data, etc., as well as the transmission of data between the main control component and the communication component and carrier monitoring component, including but not limited to drive test tasks, test results, start / stop commands, etc.

[0047] In some embodiments, the splitter switching component 102 further includes a serial port transmission channel that connects the antenna component 101 to the communication component 103 and the carrier monitoring component 104. The serial port transmission channel includes a serial port switching matrix, specifically an RS422 switching matrix 1023. A first port of the serial port switching matrix is ​​connected to the timing module 1013 of the antenna component, and a second port of the serial port switching matrix is ​​connected to the timing module 1033 of the communication component and the timing module 1042 of the carrier monitoring component.

[0048] It is understandable that the split-channel interaction component achieves timing synchronization between the antenna component, communication component, and carrier detection component through the set serial port exchange matrix.

[0049] Continue to refer to Figure 1 Antenna assembly 101 includes an antenna assembly transmitting module 1011, an antenna assembly receiving module 1012, an antenna assembly timing module 1013, and an antenna assembly antenna control module 1014. Communication assembly 103 includes a communication assembly transmitting module 1031, a communication assembly receiving module 1032, a communication assembly timing module 1033, and a communication assembly management LAN module 1034. Carrier monitoring assembly 104 includes a carrier monitoring assembly receiving module 1041, a carrier monitoring assembly timing module 1042, and a carrier monitoring assembly LAN module 1043. The transmitting module 1011 of the antenna assembly is connected to the transmitting module 1031 of the communication assembly via an uplink transmitting channel; the receiving module 1012 of the antenna assembly is connected to the receiving module 1032 of the communication assembly and the receiving module 1041 of the carrier monitoring assembly via downlink receiving channels; the timing module 1013 of the antenna assembly is connected to the timing module 1033 of the communication assembly and the timing module 1042 of the carrier monitoring assembly via a serial port transmission channel. The antenna control module 1014 of the antenna assembly is connected to the communication component management LAN module 1034 of the communication component, the carrier monitoring component LAN module 1043 of the carrier monitoring component, and the LAN module 1051 of the main control component via Ethernet transmission channels.

[0050] The downlink signal of the antenna assembly 101 is input from the antenna assembly receiving module 1012 to the downlink receiving channel of the splitter switching assembly 102. After attenuation compensation by the power divider 1022 and two low-noise amplifiers 1025, it is simultaneously input to the communication assembly receiving module 1032 and the carrier monitoring assembly receiving module 1041 for communication drive test and carrier monitoring drive test, respectively.

[0051] The antenna assembly timing module 1013 outputs a second pulse signal 1PPS and TOD information, which are then input to the RS422 switching matrix of the splitter switching component and then to the communication component timing module 1033 and the carrier monitoring component timing module 1042, respectively, for timing synchronization between the two and the wireless communication network.

[0052] The antenna control module 1014, communication component management LAN module 1034, carrier monitoring component LAN module 1043, and main control component LAN module 1051 are all connected to the LAN switching matrix 1024 of the splitter switching component. Through this LAN switching matrix, data transmission between the communication component, carrier monitoring component, and antenna component, including but not limited to RF frequency points, polarization direction, power amplification / attenuation coefficients, and servo program data, is realized. Data transmission between the main control component and the communication component and carrier monitoring component, including but not limited to drive test tasks, test results, and start / stop commands, is also achieved. The main control component LAN module 1051 of the terminal device is connected to the communication component management LAN module 1034 and the carrier monitoring component LAN module 1043, respectively, and controls the antenna component by controlling the communication component and the carrier detection component.

[0053] It is understood that in the disclosed embodiments, the communication component and the carrier monitoring component can independently perform drive test tasks in a time-sharing manner under the scheduling of the main control component. After the communication component controls the antenna component to enter the network, the carrier monitoring component can synchronously monitor the downlink signal received by the antenna component and synchronously monitor the propagation quality of the wireless air interface downlink signal of the real-time communication service. This reduces the complexity of the overall system integration and deployment caused by configuring two independent antennas, simplifies the configuration of the wireless transceiver front end of the drive test equipment, reduces the overall size and power consumption, thereby reducing the spatial environment requirements for the deployment of the drive test equipment and the amount of assembly and calibration work.

[0054] In some embodiments, the downlink trigger output module 1035 in the communication component 103 is connected to the downlink trigger input module 1045 in the carrier monitoring component 104.

[0055] Continue to refer to Figure 1 The communication component 103, through the downlink trigger output module 1035, inputs the timing (downlink reception trigger) for receiving downlink service channels after network access to the downlink trigger input module 1045 of the carrier monitoring component. The downlink trigger input module 1045 can then trigger the monitoring of downlink service channel signals based on this timing. Furthermore, the communication component can also transmit the downlink service channel time-frequency resource scheduling information received after network access to the carrier monitoring component via the Ethernet transmission channel of the splitter switch component. Based on this, the carrier monitoring component can further decode the reference signal of the downlink service channel, thereby accurately assessing the downlink channel signal attenuation, interference, and time-frequency offset.

[0056] It is understood that the carrier monitoring component in the disclosed embodiments can monitor the downlink received signal of the communication component at any time. By utilizing the downlink receive synchronization trigger signal and downlink service channel scheduling information transmitted by the communication component, the carrier monitoring component can not only monitor and analyze the signal quality of the synchronization channel and broadcast channel, but also has the ability to monitor and analyze the wireless signal quality of the downlink service channel.

[0057] In some embodiments, the uplink transmission channel, the downlink reception channel, the serial transmission channel, and the Ethernet transmission channel each include multiple connection interfaces. The splitter switch assembly further includes a power supply assembly, which includes a power control switch and a power interface.

[0058] like Figure 2 As shown, the rear panel of the splitter switch includes uplink and downlink transmission channels with transmit ports (ANT1-TX, ANT2-TX, ANT3-TX) and receive ports (ANT1-RX, ANT2-RX, ANT3-RX) corresponding to multiple antennas, serial transmission channels with timing ports (ANT1-T, ANT2-T, ANT3-T) corresponding to multiple antennas, and LAN transmission channels with control ports (LAN1, LAN2, LAN3) corresponding to multiple antennas. The rear panel also includes a device power supply port.

[0059] The front panel of the splitter switch includes uplink and downlink transmission channels, which contain downlink signal receiving ports (RX-OUT11+RX-OUT12, RX-OUT21+RX-OUT22, RX-OUT31+RX-OUT32) for multiple communication components and carrier monitoring components, and uplink signal transmission ports (TX-IN1, TX-IN2, TX-IN3) for multiple communication components. The serial port transmission channel contains clock ports (T-OUT11+T-OUT12, T-OUT21+T-OUT22, T-OUT31+T-OUT32) for multiple communication components and carrier monitoring components. The LAN transmission channel contains ports (LAN1, LAN2, LAN3) for the main control component network port, communication component management network port, and carrier monitoring component network port. The front panel also includes a device power switch.

[0060] Based on the received drive test task set, the main control component 105 schedules the control authority of the communication component 103 and the carrier monitoring component 104 over the antenna component 101, and instructs the communication component 103 and the carrier monitoring component 104 to adopt a time-sharing working mode or a simultaneous working mode to execute the corresponding drive test tasks sequentially or simultaneously and receive the test results.

[0061] In one example, the time-sharing operation mode means that the communication component 103 and the carrier monitoring component 104 have control over the antenna component 101 and perform corresponding drive test tasks on a time-sharing basis. One component can only begin antenna control and drive test tasks after the other component has completed its drive test and released its control over the antenna component. The accompanying parallel operation mode means that the communication component 103 always controls the antenna component 101 and maintains its network access status. Under this condition, the carrier monitoring component 104 can listen to the downlink signals received by the communication component 103 at any time and perform carrier monitoring drive test tasks on them.

[0062] like Figure 3 As shown, in the time-division multiplexing mode, the communication component 103 and the carrier monitoring component 104 reuse the antenna component 101:

[0063] (1) The main control component receives a set of tasks to be executed, for example: tasks 1 to N perform communication drive tests, tasks N+1 to N+M perform carrier monitoring drive tests, and tasks N+M+1 and after that, communication drive tests continue to be executed.

[0064] (2-a) If N<1, it means that the carrier monitoring drive test task is executed first, and the main control component passes through... Figure 1 The control interface, via the splitter switch, instructs the communication component to disconnect from the network and stop sending antenna control commands.

[0065] (3-a) The main control component instructs the carrier monitoring component to send antenna control commands through the control interface, receive the wireless downlink synchronization channel and broadcast channel, and perform carrier monitoring drive test tasks.

[0066] (4-a) After the carrier monitoring drive test is completed, the main control component determines whether to continue the communication drive test. If it continues, it executes 2-b to 4-b; otherwise, it terminates the drive test.

[0067] (2-b) If N≥1, or if the main control component determines in 4-a to continue executing the communication drive test task, the main control component instructs the carrier monitoring component to stop sending antenna control commands and stop listening to downlink signals through the control interface.

[0068] (3-b) The main control component instructs the communication component to send antenna control commands and access the wireless network through the control interface to perform communication drive test tasks.

[0069] (4-b) After the communication drive test is completed, the main control component determines whether to continue the carrier monitoring drive test. If it continues, it executes 2-a to 4-a; otherwise, it terminates the drive test.

[0070] like Figure 4 As shown, in the accompanying operating mode, the antenna component is multiplexed between the communication component and the carrier monitoring component:

[0071] (1) The main control component receives a set of tasks to be executed, such as: tasks 1 to N execute communication drive tests or carrier monitoring drive tests individually, and tasks M to O (M≤N) execute carrier monitoring drive tests together.

[0072] (2) The main control component instructs the communication component to send antenna control commands and access the wireless network.

[0073] (3-a) If the task set indicates that the carrier monitoring task should be executed first, the main control component instructs the carrier monitoring component to listen to the downlink synchronization channel and broadcast channel after the communication component enters the network through the control interface, and to execute the carrier monitoring drive test task.

[0074] (4-a) After the carrier monitoring drive test is completed, the master controller determines whether to continue the communication drive test. If yes, then execute 3-b to 4-b; otherwise, end the drive test.

[0075] (3-b) If the task set indicates that communication drive test should be performed first, or if the master control component determines in 4-a to continue performing communication drive test, the master control component instructs the communication component to perform communication drive test through the control interface. If the task set indicates that carrier monitoring drive test should be performed along with communication drive test, the master control component synchronously instructs the carrier monitoring component to listen to the downlink synchronization channel and broadcast channel; instructs the communication component to output the downlink receive trigger signal and downlink service channel scheduling information to the carrier monitoring component; on this basis, the carrier monitoring component further listens to the downlink service channel; the carrier monitoring component performs carrier monitoring drive test.

[0076] (4-b) When the communication drive test is completed, the master control determines whether to continue the carrier monitoring drive test. If yes, the master control component instructs the communication component to continue controlling the antenna and maintaining network access, but stops the communication drive test and then executes 3-a. Otherwise, the drive test ends.

[0077] It is understandable that the main control component, based on the received drive test task set, schedules the control authority of the communication component and carrier monitoring component over the antenna component through the antenna splitter switching component. In addition to supporting time-division multiplexing operation, it also supports accompanying operation mode. That is, after the communication component controls the antenna and connects to the network, the carrier monitoring component can synchronously monitor the downlink signal received by the antenna component, enabling it to simultaneously perform carrier monitoring drive test tasks and synchronously monitor the propagation quality of the downlink signal over the wireless interface during real-time communication services. The communication component provides the carrier monitoring component with a downlink reception synchronization trigger signal and decoded downlink service channel scheduling information. Based on this, the carrier monitoring component performs real-time monitoring of the propagation quality of the wireless interface signal over the downlink service channel.
