Embodiments for Carrying Out the Invention

[0011] The realization of the object, functional features and advantages of the present application will be further described in conjunction with the embodiments while referring to the accompanying drawings.

[0012] The specific embodiments described here are only used for interpreting the present application and do not limit the present application.

[0013] Referring to FIG. 1, FIG. 1 is a schematic configuration diagram of an operating device of a hardware operating environment according to the solution means of an embodiment of the present application.

[0014] In this embodiment, the operating device of the hardware operating environment according to the solution means of the embodiment of the present application may be a communication device including a control device of a communication networking system, and the communication device may be a linear chain-type networking control device for high-speed railways or highways. According to different design needs in actual applications, of course, the operating device may be connected to the communication networking system or integrated within the communication networking system, and may be other terminal devices capable of controlling the communication networking system. For example, specifically, the operating device may be a terminal such as a smartphone, a PC, or a tablet.

[0015] As shown in Figure 1, the operating device may include a processor 1001, for example, a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and memory 1005. Here, the communication bus 1002 is used to enable connection communication between these components. The user interface 1003 may include a display, an input unit, for example, a keyboard, and may further include a standard wired interface and a wireless interface. The network interface 1004 may include a standard wired interface and a wireless interface (for example, a Wireless-Fidelity (WI-FI) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), for example, disk memory. The memory 1005 may be a storage device independent of the processor 1001.

[0016] As those skilled in the art will understand, the configuration shown in Figure 1 does not constitute a limitation on the operating equipment, and more or fewer components, or a combination of several or different components, may be used.

[0017] As shown in Figure 1, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a computer program.

[0018] In the operating device shown in Figure 1, the network interface 1004 is mainly used for data communication with other devices, and the user interface 1003 is mainly used for data interaction with the user. The processor 1001 and memory 1005 in the operating device of the present invention may be provided within the operating device, and the operating device performs the following operations by calling a computer program stored in the memory 1005 via the processor 1001: namely, determining a mobile object in a communication scenario, and sequentially controlling the remote radio units to provide uplink and downlink network coverage to a user terminal in the mobile object, based on the direction of travel of the mobile object and the physical order of a plurality of remote radio units in a communication networking system.

[0019] Exemplary, the processor 1001 can call a computer program stored in memory 1005 to perform the following operations: namely, determining which of the multiple remote radio units is currently providing network services to a user terminal on the mobile body based on the direction of travel of the mobile body and the physical order of the multiple remote radio units in the communication networking system; and, when the mobile body enters the network coverage area of ​​the current remote radio unit, adjusting the antenna switch of the next remote radio unit to control the current remote radio unit and the next remote radio unit to simultaneously provide uplink and downlink network coverage to the user terminal.

[0020] For example, the processor 1001 may call a computer program stored in memory 1005 to perform the following operations: obtain the number of user terminals covered by the current remote wireless unit, and determine that the mobile entity has entered the network coverage area of ​​the current remote wireless unit if the number exceeds a preset threshold.

[0021] For example, the processor 1001 can call a computer program stored in memory 1005 to perform the following operations: acquire measurement information continuously reported from the user terminal; determine the target remote radio units with the strongest signals among the multiple remote radio units based on the measurement information; and determine the physical order of the multiple remote radio units based on the continuous change pattern of the target remote radio units.

[0022] For example, the processor 1001 may call a computer program stored in memory 1005 to perform the following operations: if there is no opposing mobile object within the default network coverage area of ​​the next remote radio unit, adjust the antenna switch of the next remote radio unit to connect it to the antenna panel on the same side as the current remote radio unit, where the direction of travel of the mobile object is opposite to the direction of travel of the opposing mobile object.

[0023] Exemplary, the antenna panel on the same side of the current remote radio unit includes a first antenna panel and a second antenna panel. The processor 1001 can call a computer program stored in memory 1005 to perform the following operations: if the current remote radio unit is connected to the first antenna panel, adjust the antenna switch of the next remote radio unit to connect the (i+1)th remote radio unit to either the first or second antenna panel.

[0024] For example, the processor 1001 can call a computer program stored in memory 1005 to perform the following operations: namely, to control the multiple remote wireless units to provide uplink and downlink network coverage for their respective default network coverage areas at a predetermined time, where the predetermined time is the time when the user terminal reports a channel sounding reference signal to the communication networking system, or the time when the communication networking system transmits system information to the user terminal.

[0025] Based on the configuration of the operating equipment of the hardware operating environment relating to the solution of the embodiment of the present application described above, we first propose an overall concept of a control method for a communication networking system provided by the solution of the embodiment of the present application.

[0026] Communication networking schemes for high-speed rail or highways typically employ a linear chain networking system. This system involves deploying two network RRUs (Remote Radio Units) back-to-back on the same pole when setting up communication base stations. Each RRU is connected to a corresponding antenna panel, enabling communication network transmission in two directions, back-to-back.

[0027] Related technologies constantly increase the number of network RRUs and reduce the distance between two base stations to improve coverage and communication detection speed for high-speed users. However, this approach offers very limited improvement in the uplink reception and downlink transmission capabilities of the network in the overlapping area of ​​two high-speed users' RRUs.

[0028] In response to the above phenomenon, the embodiment of the present invention proposes a method for controlling a communication networking system. When a high-speed moving object such as a vehicle, high-speed train, or airplane is identified and determined to be part of the communication scenario to which the communication networking system belongs, the system sequentially controls the multiple remote radio units in the communication networking system to provide uplink and downlink network coverage to high-speed users in the moving object, based on the specific direction of travel of the moving object and the physical order of the multiple remote radio units in the communication networking system.

[0029] Thus, compared to related technologies that improve high-speed user coverage and communication detection speed simply by increasing the number of network RRUs and reducing the distance between two base stations, the embodiment of the present invention, by simply identifying whether or not there is a vehicle and based on the physical order of each remote radio unit in the cell, can pre-adjust the antenna switch of an adjacent remote radio unit when a high-speed moving object such as a vehicle, high-speed train or airplane is about to enter the network coverage area of ​​a certain remote radio unit. This achieves the effect of sharing downlink power between two remote radio units and / or doubling the number of transmitting and receiving antennas, thereby flexibly changing the power of the remote radio units in accordance with the movement of the moving object, achieving the objectives of uplink and downlink joint demodulation and transmission of the network, and ultimately significantly improving the uplink and downlink detection speed of high-speed users.

[0030] Based on the overall concept of the control method for a communication networking system provided by the solutions of the embodiments of the present application described above, we propose various embodiments of the control method for a communication networking system of the present application.

[0031] The method for controlling a communication networking system according to the present invention is applicable to the above-described operating device, which may be a communication device including a control device for the communication networking system, which can be connected to or integrated within the communication networking system, thereby enabling control of the communication networking system. Based on the different design needs of actual applications, in different executable embodiments, the method for controlling a communication networking system according to the present invention can be applied not only to other terminal devices but also to other terminal devices. For ease of understanding and to describe the technical solution, the method for controlling a communication networking system according to the present invention will be described below with the communication device as the implementing body of the solution.

[0032] Referring to Figure 2, Figure 2 is a flowchart showing the steps of a first embodiment of the control method for a communication networking system of the present invention. Although the flowchart shows a logical sequence, in some cases the control method for a communication networking system of the present invention, as well as the steps shown or described herein, may be performed in an order different from the order shown.

[0033] As shown in Figure 2, in a first embodiment of the method for controlling a communication networking system of the present invention, the method for controlling a communication networking system provided by the embodiment of the present invention may include the following steps: Step S10, Determine the mobile entity in the communication scenario.

[0034] In this embodiment, the communication device identifies a high-speed user in the communication scenario in which it is located, and determines whether or not a moving object such as a vehicle, high-speed train, or airplane operating at high speed has appeared in that communication scenario at that time.

[0035] In this embodiment and each other executable embodiment, the communication networking system is a communication networking system (also called a high-speed communication networking system) developed to suit relatively mobile user groups in the communications field, and the communication networking system can provide uplink and downlink network coverage to mobile user groups (particularly high-speed moving user groups). Exemplarily, the communication networking system may be a linear chain networking system specifically in a high-speed rail scenario or a highway scenario, and the communication equipment may be equipment that specifically controls the provision of network coverage to high-speed users in the linear chain networking system, for example, a Building Baseband Unit (BBU), or the communication equipment may be equipment that specifically provides network coverage to high-speed users directly, for example, a Remote Radio Unit (RRU).

[0036] Furthermore, the communication scenarios described above are, in other words, communication scenarios in which the above-described communication networking system is deployed, and are scenarios in which user groups are relatively mobile, such as the high-speed rail scenario, highway scenario, and subway and sea routes in the communication field. In the communication scenarios in which the above-described communication networking system is deployed, the configuration of the base station BBU of the communication networking system is shown in Figure 3, that is, A single base station is equipped with two RRUs and four antenna panels (specifically, 8T antennas), where each RRU is connected to only one antenna panel at a time, and the base station controls which antenna panel each RRU is specifically connected to using a switch. Based on this, the connection between a single RRU and an antenna panel at the base station can be switched in two ways by the switch: one is to connect the RRU to the left 8T antenna and disconnect the right 8T antenna, and the other is to connect the RRU to the right 8T antenna and disconnect the left 8T antenna.

[0037] In one embodiment, corresponding to a communication networking system configured with two RRUs located at one base station as described above, there are a total of three combinations of connections between the two RRUs at the base station and the antenna panels: namely, the two RRUs are connected to the two antenna panels on the left side of the base station (as shown in Figure 4a), the two RRUs are connected to one antenna panel on the left side and one antenna panel on the right side of the base station (as shown in Figure 4b), and the two RRUs are connected to the two antenna panels on the right side of the base station (as shown in Figure 4c).

[0038] In one embodiment, the connection state shown in Figure 4b above, in which the two RRUs are connected to one antenna panel on the left side and one antenna panel on the right side of the base station, is the initial default state in which the two RRUs and antenna panels at the base station in the communication networking system are connected.

[0039] As an example, assuming the communication equipment is the base station BBU described above, in the high-speed rail communication scenario shown in Figure 5, the base station BBU provides uplink and downlink network coverage to high-speed users in the current communication scenario by controlling two remote radio units (RRUs) assembled within it. During the operation of the high-speed rail train, the base station BBU continuously monitors the number of identified high-speed users, and if this number meets a certain threshold, it determines that the high-speed rail train has appeared in the current communication scenario and identifies the high-speed rail train as the currently identified high-speed operating mobile entity.

[0040] In step S20, based on the direction of travel of the mobile body and the physical order of the multiple remote radio units in the communication networking system, the remote radio units are sequentially controlled to provide uplink and downlink network coverage to user terminals on the mobile body.

[0041] In this embodiment, the communication device determines, at the same time as or after determining that a mobile object traveling at high speed in a communication scenario has appeared, further determines the direction of travel of the mobile object. Based on the direction of travel and the physical order of the multiple remote radio units in the communication networking system in which it is located, the communication device can sequentially control the multiple remote radio units to provide uplink and downlink network coverage to user terminals that are also traveling at high speed on the mobile object.

[0042] In this embodiment and in each other executable embodiment, the communication networking system control method of the present invention utilizes a cell merger networking scheme in which the base station BBU designs algorithms for vehicle approach identification, RRU positioning, and user assignment to obtain the location of RRUs where user groups are distributed, and then adjusts the transmit power and coverage range of each antenna device. In this way, the communication networking system control method of the present invention can generate a gain of 3 dB by rationally utilizing RRU power sharing, thereby improving downlink coverage and downlink performance in communication scenarios such as high-speed rail scenarios, highway scenarios, subways, and air routes. On the other hand, by doubling the number of antennas in the same direction of the base station, it is possible to achieve four times the reinforcement of uplink and downlink antennas when a user is in the overlapping coverage area of ​​two base stations. In other words, the control method for the communication networking system of the present invention can achieve the objective of joint equalization by uplink joint reception and improve uplink reception performance, and can achieve the objective of coherent JT by multiple RRU downlink joint beamforming transmissions, and can achieve a gain of 3-6 dB for both uplink and downlink, thereby effectively improving user perception in areas with weak coverage.

[0043] Based on this, step S20 described above may include the following steps: Step S21, based on the direction of travel of the mobile body and the physical order of the multiple remote radio units in the communication networking system, determine which of the multiple remote radio units is currently providing network services to the user terminal on the mobile body in sequence.

[0044] In this embodiment, after the communication device further identifies and determines the direction of travel of a mobile body operating at high speed and the physical order of multiple remote radio units in the communication networking system in which it is located, it can determine, based on the direction of travel and the physical order, which remote radio unit is currently providing network services sequentially to user terminals on the mobile body while the mobile body is in motion.

[0045] In this embodiment and in each other executable embodiment, when a mobile body enters the network coverage range of a current remote radio unit among a plurality of remote radio units, the communication device determines that the mobile body has entered the current remote radio unit at the current time, thereby enabling the current remote radio unit to provide network services to the user terminal on the mobile body. Based on this, the communication device can determine each current remote radio unit that a mobile body traveling at high speed has sequentially entered among a plurality of remote radio units.

[0046] Step S22, when the mobile unit enters the network coverage area of ​​the current remote radio unit, the antenna switch of the next remote radio unit of the current remote radio unit is adjusted to control the current remote radio unit and the next remote radio unit to simultaneously provide uplink and downlink network coverage to the user terminal.

[0047] In this embodiment, when the communication device determines that a high-speed moving object has entered the network coverage range of a current remote radio unit among a plurality of remote radio units, the communication device immediately determines the next remote radio unit adjacent to the current remote radio unit in the direction of travel of the moving object, in order to enhance its awareness of uplink and downlink network coverage for high-speed users throughout the entire communication scenario. The communication device then adjusts the antenna switch of the next remote radio unit to control the current remote radio unit and the next remote radio unit to simultaneously provide uplink and downlink network coverage to user terminals on the moving object, respectively.

[0048] In this embodiment and in each other executable embodiment, the communication equipment can determine the physical order of multiple remote radio units (RRUs) in a communication networking system based on changes in the strength of the measured signal of a user terminal operating at high speed. This allows for advance notification to adjacent RRUs to adjust their antennas when a moving object, such as a vehicle operating at high speed, is about to enter one of the RRUs, thereby achieving the effect of sharing downlink power between the two RRUs and doubling the number of transmit and receive antennas, ultimately achieving the objectives of uplink and downlink joint demodulation and transmission, and effectively improving the uplink and downlink sensing speed of the user's network services in high-speed communication scenarios.

[0049] For example, as shown in Figure 6, if the communication equipment functions as a base station BBU in a communication networking system, after the base station BBU identifies that a high-speed mobile has entered the current remote radio unit RRU1, the base station BBU determines, based on the pre-learned physical order of multiple RRUs in each communication networking system (RRU1-RRU2-RRU3-RRU4-RRU5-RRU6) and the direction of travel of the mobile, that the mobile has entered the network coverage range of RRU1. In this case, the base station BBU must connect the next remote radio unit RRU2 adjacent to RRU1 in the direction of travel to the antenna on the right side of the base station. This allows RRU2, together with RRU1, to simultaneously provide network uplink and downlink services to the user terminal on the mobile in the same direction. Thus, for the user terminal on the high-speed mobile, this is equivalent to doubling the number of antennas providing network uplink and downlink services, and the downlink power also increases by 3 dB.

[0050] In one embodiment, for the original coverage area of ​​the following remote radio unit RRU2 described above, the communication equipment, acting as a base station BBU, switches RRU2 to connect to the left antenna of the base station only at the SRS time (the time when the user terminal reports a channel sounding reference signal to the communication networking system). At this time, the antenna connection state of the i-th remote radio unit RRU1 does not need to change at all so that both the uplink and downlink network data of the user terminal are jointly transmitted and received by the two RRUs.

[0051] Based on this, in this embodiment and each other executable embodiment, the method for controlling the communication networking system of the present invention may further include the following steps.

[0052] Step S30, the multiple remote wireless units are controlled to provide uplink and downlink network coverage for their respective default network coverage areas at a predetermined time, where the predetermined time is the time when the user terminal reports a channel sounding reference signal to the communication networking system, or the time when the communication networking system transmits system information to the user terminal.

[0053] In this embodiment, in the process of sequentially controlling remote radio units to provide uplink and downlink network coverage to a user terminal in a mobile vehicle operating at high speed, the communication device controls one or more of the multiple remote radio units to provide uplink and downlink network coverage to their respective default network coverage areas as soon as it detects that the current time has reached the time when the user terminal reports a channel sounding reference signal to the communication networking system, or as soon as it detects that the current time has reached the time when the communication networking system transmits system information to the user terminal.

[0054] In this embodiment and each other executable embodiment, the default network coverage area of ​​a remote radio unit is controlled to be the network coverage area when the remote radio unit provides uplink and downlink network services, when the connection state between the remote radio unit and the antenna panel at the base station is the initial default state shown in Figure 4b above.

[0055] For example, assuming that the communication networking system on which the communication equipment is located employs a cell merger networking scheme, the communication equipment can connect to multiple remote radio unit RRUs when functioning as a base station BBU, and the communication networking system can utilize a common, identical Cell ID and its associated common channel, with each remote radio unit RRU connected to an antenna panel. The initial state of the antennas is that the base station-side RRU is connected to its own antenna panel (as shown in Figure 4b). In this case, since the antenna panels on both sides of the base station face their respective sides, uplink and downlink network coverage can be obtained on both the left and right sides of the base station. However, as shown in Figure 7, when a user terminal appears in a mobile vehicle operating at high speed, the user terminal will only receive signals from an antenna connected to one RRU, and uplink and downlink traffic will be transmitted and received independently by that RRU.

[0056] Furthermore, if the communication equipment acts as a base station BBU, it places the same SRS resource on each of the N remote radio units (RRUs) belonging to a single high-speed cell. As a result, at the periodic point in time for SRS placement, the base station BBU switches the connection state between each RRU and the antenna to the initial default state shown in Figure 4b, and immediately after that SRS point in time, it switches the connection state between each RRU and the antenna back to the connection state prior to that SRS point in time. For example, in a 5ms frame structure, if four SRS symbols are placed in the S slot, and the base station BBU controls the connection states between RRU1 and RRU2 and the antenna so that both RRU1 and RRU2 are connected to the left antenna panel of the base station, then at the start time of the first SRS symbol, the base station BBU needs to adjust the connection state between RRU2 and the antenna so that RRU2 is connected to the right antenna panel of the base station, while the connection state between RRU1 and the antenna does not change. In this case, the connection states between RRU1 and RRU2 and the antenna are both in the initial default state. After the transmission of the four SRS symbols is complete, the connection status between RRU1 and the antenna remains unchanged, but the connection status between RRU2 and the antenna is controlled by the base station BBU and immediately switched back to its original state, connected to the left antenna of the base station.

[0057] In this embodiment, the communication device identifies a high-speed user in the high-speed communication scenario in which it is located, and determines whether a mobile object operating at high speed in that communication scenario has appeared at that time. Simultaneously with or after determining that a mobile object operating at high speed in the communication scenario has appeared, the communication device further determines the direction of travel of the mobile object, thereby enabling the communication device to sequentially control the multiple remote radio units in the communication networking system in which it is located to provide uplink and downlink network coverage to user terminals on the mobile object, based on the direction of travel of the mobile object and the physical order of the multiple remote radio units in the communication networking system in which it is located.

[0058] Thus, compared to related technologies that improve network coverage and communication detection speed for user terminals in high-speed communication scenarios simply by increasing the number of network RRUs and reducing the distance between two base stations, the embodiment of the present invention, by simply identifying whether or not there is a vehicle and based on the physical order of each remote radio unit in the cell, can pre-adjust the antenna switch of an adjacent remote radio unit when a high-speed moving object such as a vehicle, high-speed train or airplane is about to enter the network coverage area of ​​a certain remote radio unit. This achieves the effect of sharing downlink power between two remote radio units and / or doubling the number of transmit / receive antennas, thereby flexibly changing the power of the remote radio units in accordance with the movement of the moving object, achieving the objectives of uplink and downlink joint demodulation and transmission of the network, and ultimately significantly improving the uplink and downlink detection speed for high-speed users.

[0059] Based on the first embodiment of the communication networking system control method of the present invention described above, a second embodiment of the communication networking system control method of the present invention is proposed.

[0060] In a second embodiment of the method for controlling a communication networking system of the present invention, the method for controlling a communication networking system of the present invention may further include the following steps: Step S40, obtain the number of user terminals covered by the current remote radio unit. Step S50, if the number exceeds a preset threshold, determine that the mobile has entered the network coverage area of ​​the current remote radio unit.

[0061] In this embodiment, when a communication device determines whether a high-speed moving object has entered the network coverage area of ​​a current remote radio unit among multiple remote radio units, it uses the same principle as determining whether a vehicle is approaching in the communication scenario in which it is located to obtain the number of user terminals on the moving object covered by the current remote radio unit and to detect in real time whether this number exceeds a preset threshold. If the number exceeds the preset threshold, it is determined that the moving object has entered the uplink and downlink network coverage area of ​​the current remote radio unit at the current time.

[0062] In this embodiment and each other executable embodiment, the preset threshold can be set to 200, 500, and 800, for example. Because the number of user groups installed on moving objects such as high-speed vehicles, high-speed rail, subways, or airplanes differs in different high-speed communication scenarios, the preset threshold can be flexibly set according to the different design needs of the actual application; that is, the control method for the communication networking system of the present invention does not limit the magnitude of the preset threshold.

[0063] As an example, as shown in Figure 8, assuming that the communication equipment is a base station BBU in a communication networking system, in a high-speed communication scenario, i.e., a high-speed rail scenario, where the base station BBU is located, when a mobile vehicle traveling at high speed attempts to enter cell 2, the base station BBU of that cell determines whether or not the mobile vehicle should enter RRU1 based on whether the number of user terminals covered by RRU1 in cell 2 meets a certain threshold.

[0064] Furthermore, after a high-speed moving object has entered RRU1 in cell 2, the base station BBU can simultaneously determine the direction of travel of the moving object, i.e., the train is leaving cell 1 and entering cell 2, based on the original cell from which the moving object was switched, i.e., cell 1. At this time, the base station BBU in cell 1 can receive identification information that the object is leaving, and the base station BBU in cell 3, which is adjacent to cell 2, can receive identification information that the object will soon be entering.

[0065] If the base station BBU detects that the number of user terminals covered by RRU1 in cell 2 does not meet the condition (does not exceed the threshold above), the base station BBU must check whether there are any other states that have already been transmitted (identification information for a train departing or identification information for a train arriving soon). If there are, the original state is maintained; otherwise, the state becomes "no trains."

[0066] In one embodiment, the control method for the communication networking system of the present invention may further include the following steps: Step S60: Acquire measurement information continuously reported from the user terminal. Step S70: Determine the plurality of target remote radio units with the strongest signals among the plurality of remote radio units based on the measurement information. Step S80: Determine the physical order of the plurality of remote radio units based on the continuous change pattern of the target remote radio units.

[0067] In this embodiment, when a communication device learns the physical order of multiple remote radio units in a communication networking system where it is located, it continuously acquires measurement information that a user terminal has continuously reported to the communication networking system. Subsequently, based on the measurement information continuously reported by the terminal device, the communication device can determine the multiple target remote radio units with the strongest signals among the multiple remote radio units. As a result, after generating a continuous change pattern of the multiple target remote radio units, the communication device can learn and determine the physical order of the multiple remote radio units in the entire communication networking system based on this continuous change pattern.

[0068] For example, if a communication device functions as a base station BBU in a communication networking system, the base station BBU receives SRS measurement information continuously reported from user terminals in high-speed mobile devices and identifies the connection direction of each AAU based on the SRS measurement information. The user terminal in the mobile device receives RRU measurement information for each cell and selects the target RRU with the strongest signal among multiple RRUs based on the magnitude of the measured values ​​in the RRU measurement information. The base station BBU can then obtain a bitmap of the physical order of multiple RRUs across the cell by maintaining the changing patterns of the target RRU with the strongest signal reported by each high-speed user.

[0069] Based on the first and / or second embodiments of the communication networking system control method of the present invention described above, a third embodiment of the communication networking system control method of the present invention is proposed.

[0070] In a third embodiment of the method for controlling a communication networking system of the present invention, the action of "adjusting the antenna switch of the next remote radio unit" in step S22 described above may include the following steps: Step S221, if there is no opposing mobile object within the default network coverage area of ​​the next remote radio unit, adjust the antenna switch of the next remote radio unit so that the next remote radio unit is connected to the antenna panel on the same side of the current remote radio unit, where the direction of travel of the mobile object is opposite to the direction of travel of the opposing mobile object.

[0071] In this embodiment, when the communication device adjusts the connection between the next remote radio unit and the antenna, it first determines whether there is an opposing mobile object within the default network coverage area of ​​the next remote radio unit that has already been determined to enter the network coverage area of ​​the current remote radio unit. The communication device then determines that there is no opposing mobile object within the default network coverage area of ​​the next remote radio unit, and only then begins to adjust the antenna switch of the next remote radio unit to connect it to the antenna panel located on the same side of the current remote radio unit, thereby controlling both the current and next remote radio units and providing uplink and downlink network coverage to user terminals in mobile objects within the current remote radio unit's network coverage range.

[0072] In one embodiment, when a communication device detects that an opposing mobile object is within the default network coverage area of ​​the next remote radio unit, even if the mobile object is traveling at high speed and has entered the network coverage area of ​​the current remote radio unit, the communication device does not need to make any adjustments to the antenna switch of the next remote radio unit. This is done to ensure that a user terminal on the opposing mobile object can obtain at least the uplink and downlink network services provided by the next remote radio unit.

[0073] In one embodiment, the antenna panel on the same side of the current remote radio unit described above includes a first antenna panel and a second antenna panel. Based on this, the step described above, "adjusting the antenna switch of the next remote radio unit to connect the next remote radio unit to the antenna panel on the same side of the current remote radio unit," may include the step of adjusting the antenna switch of the next remote radio unit to connect the (i+1)th remote radio unit to either the first antenna panel or the second antenna panel, if the current remote radio unit is connected to the first antenna panel.

[0074] In this embodiment, when the communication device determines that there is no opposing mobile object within the default network coverage area of ​​the next remote radio unit, and adjusts the antenna switch of the next remote radio unit, if there are two antenna panels on the same side of the current remote radio unit, namely a first antenna panel and a second antenna panel, and the current remote radio unit is already connected to the first antenna panel, the communication device can adjust the antenna switch of the next remote radio unit to connect the next remote radio unit to the first antenna panel, or adjust the antenna switch of the next remote radio unit to connect the next remote radio unit to the second antenna panel.

[0075] In one embodiment, if there is only one antenna panel on the same side of the current remote radio unit and that antenna panel is already connected to the current remote radio unit, the communication device can adjust the antenna switch of the next remote radio unit to connect to the first antenna panel, i.e., the first antenna panel is simultaneously connected to two remote radio units: the current remote radio unit and the next remote radio unit adjacent to the current remote radio unit.

[0076] In this embodiment and in each other feasible embodiment, if there is only one antenna panel on each side of the base station, the base station BBU can control both remote radio unit RRUs on both sides of the base station to connect to the antenna panel on one side of the base station when a high-speed user is on one side, thereby achieving superposition of power from the two remote radio unit RRUs, in which case there is still a 3 dB gain on the downlink. When there is only one antenna panel on each side of the base station, the connection status between the remote radio unit RRU and the antenna panel is as shown in Figures 9a, 9b, and 9c, respectively.

[0077] In one embodiment, as shown in Figure 10, a preferred embodiment of the control method for the communication networking system of the present invention is proposed, in which the control method for the communication networking system of the present invention may include the following steps.

[0078] 1. A base station BBU of one cell is connected to multiple remote radio units (RRUs), and the cell uses the same common Cell ID and its associated common channel. The connection state between each remote radio unit (RRU) and antenna is the initial default state, and as shown in Figure 4b, the RRU on the base station side is connected to the antenna panel on its own side. In this case, the antennas on both sides of the base station face their respective sides, and uplink and downlink network coverage is obtained on both the left and right sides. As a result, as shown in Figure 7, when a user enters the coverage area of ​​an RRU on one side of the base station, the user's terminal equipment receives only the signal from the antenna connected to one of those RRUs, and uplink and downlink traffic are also sent and received independently by that RRU.

[0079] 2. The communication equipment, acting as a base station BBU, places the same SRS resource on each of the N remote radio units (RRUs) belonging to a single high-speed cell. This allows the base station BBU to switch the connection state between each RRU and the antenna to the initial default state shown in Figure 4b at the time of SRS placement, and then immediately after that SRS time, switch the connection state between each RRU and the antenna back to the connection state prior to that SRS time. For example, in a 5ms frame structure, if four SRS symbols are placed in the S slot, and the base station BBU controls the connection states between RRU1 and RRU2 and the antenna so that both RRU1 and RRU2 are connected to the left antenna panel of the base station, then at the start time of the first SRS symbol, the base station BBU needs to adjust the connection state between RRU2 and the antenna so that RRU2 is connected to the right antenna panel of the base station, while the connection state between RRU1 and the antenna remains unchanged. In this case, the connection states between RRU1 and RRU2 and the antenna are both in the initial default state. After the transmission of the four SRS symbols is complete, the connection status between RRU1 and the antenna remains unchanged, but the connection status between RRU2 and the antenna is controlled by the base station BBU and immediately switched back to its original state, connected to the left antenna of the base station.

[0080] 3. While a train is in operation, the base station BBU determines whether there is a mobile object operating at high speed, i.e., a train, based on whether the number of high-speed users meets a certain threshold. If the number of high-speed users meets the threshold, it identifies that a train is approaching, and at the same time, the high-speed users switch source cells to obtain the direction of travel of the train and transmit this direction of travel to the next adjacent high-speed cell. As shown in Figure 8, when a train is about to enter cell 2, the base station BBU of that cell determines the approaching train based on whether the number of high-speed users meets a certain threshold. If the condition is met, it indicates that a train has arrived, and at the same time, it obtains the direction of the approaching train from the source cell to which the high-speed users have switched. That is, the train is leaving cell 1, transmits the departure identification information to the base station BBU of cell 1, and transmits the identification information that it will soon enter to another adjacent cell of cell 2, i.e., the base station BBU of cell 3. Conversely, if the number of high-speed users does not meet the condition, it is necessary to check whether there are any other states that have already been transmitted. If there are, the original state is maintained; otherwise, the state becomes "no train".

[0081] 4. The base station BBU identifies the connection direction of each AAU based on the measurement information of the high-speed user SRS. Each high-speed user in a cell receives the measurement information of each RRU within that cell, and based on the magnitude of the measurement, selects the RRU with the strongest signal currently, thereby obtaining a bitmap of the physical order of the RRUs in the cell by maintaining the changing pattern of the strongest RRU for each high-speed user.

[0082] 5. After receiving identification information that a train is approaching, the BBU base station determines the RRU location to which the high-speed user belongs at the current time based on measurement information continuously reported from the high-speed user's terminal equipment UE, selects the currently used switch state, notifies the RRU of the antenna switch control, thereby determining the connection relationship between the RRU and the antenna. Based on the RRU with the strongest signal held in 4, the total number of users covered by each RRU is statistically calculated according to the sliding window method, the first N statistical windows of this cell are calculated for each time step, and the number of users of a given RRU UeNum_RRU j If the ratio of RRUs to the total number of users exceeds a certain threshold, the base station BBU, based on the bitmap relationship of the train's direction of travel and the physical order of the RRUs obtained in steps 3 and 4, notifies another RRU on the pole to switch its state and change its connection state with the antenna. At the same time, it may also notify the next RRU of the state adjustment or the next cell of the state adjustment.

[0083]

number

[0084] If the user-proportional sum of adjacent RRUs between two different poles (base stations) exceeds a threshold, the base station BBU notifies the other RRU on the two poles to switch the state and change the connection state with the antenna. It can also notify the next RRU of the state adjustment or the next cell of the state adjustment. Detailed information on the switch state changes is as follows:

[0085] 501, As shown in Figure 11, when there are no approaching vehicles, the connection between each RRU and the antenna returns to the initial default state shown in Figure 4b, achieving cell beam coverage and independent transmission of uplink and downlink.

[0086] As shown in Figure 12, after the train enters RRU1, the base station BBU identifies that the train is approaching and, based on the location information of each RRU learned in step 4 (the order of the RRUs is RRU1-RRU2-RRU3-RRU4-RRU5-RRU6) and the direction of the approaching train, controls the connection between RRU2 and the antenna to switch RRU2 to the antenna on the right side of the base station when the user proportion for RRU1 reaches a threshold, thereby providing uplink and downlink services to high-speed users in the same direction together with RRU1. In this case, the user terminal on the train is equivalent to doubling the uplink and downlink antennas, and the downlink power is also increased by 3 dB. On the other hand, for the original coverage area of ​​RRU2, only at SRS time, the base station BBU controls the connection between RRU2 and the antenna to switch RRU2 to the antenna on the left side of the base station, so that the connection state between RRU1 and the antenna remains unchanged and both uplink and downlink for users are transmitted and received jointly by the two RRUs.

[0087] 503, As shown in Figure 13, as the train moves, some users begin to enter RRU2, and since RRU1 and RRU2 are on the same base station, neither the number of users in RRU1 nor RRU2 meets the proportionality requirement. In this case, the base station BBU needs to control the connection between RRU2 and the antenna to switch to the initial default state, that is, to adjust so that RRU2 is connected to the left antenna of the base station and the antenna connected to RRU1 does not change.

[0088] 504, As shown in Figure 14, as the train moves, the proportion is satisfied when a user enters RRU2. In this case, the base station BBU needs to control the connection between RRU1 and the antenna to switch to the antenna on the left side of the base station, so that RRU2 does not change. At the same time, the base station BBU further determines the next adjacent RRU3 and RRU4 based on the bitmap of the physical order of the RRUs obtained in 4, thereby controlling the connection between RRU4 and the antenna to switch to the antenna on the side where RRU3 is located, so that the connection between RRU3 and the antenna does not change. In this way, the user receives both the 3dB power of RRU1 and the 3dB power gain of RRU4, and together the uplink can be received jointly by the four RRUs, and the downlink can be transmitted jointly by the four RRUs.

[0089] 505, As shown in Figure 15, as the train moves, the train enters RRU3, and at this time, neither the users of RRU1 nor RRU2 meet the proportionality requirement. However, RRU2 and RRU3 are not on the same pole, and the sum of the user proportionality requirements for RRU2 and RRU3 meets the threshold. In this case, the base station BBU must maintain the connection status between each RRU and the antenna following the same process as in 504.

[0090] 506. As the train moves, in cell 1, the train passes through RRU4 / RRU5, and the processing is the same as in 501-505 above. However, when the train arrives at RRU6, RRU5 in cell 1 is connected to the left side of the antenna. In this case, the base station BBU decides, based on the direction of the approaching train, that the train will enter cell 2. If there are no other trains in cell 2 at this time, the base station BBU controls RRU2 in cell 2 to be connected to the antenna on the right side of the base station (see Figure 16). On the other hand, if there are other trains in cell 2, train 2 enters RRU2 at this time and enters RRU1 at the next time. In this case, the base station BBU cannot adjust the connection between RRU1 or RRU2 in cell 2 and the antenna. That is, in this case, RRU1 and RRU2 in cell 2 each maintain their initial default state of connection to the antenna (see Figure 17), otherwise a relatively large gap would occur in the coverage of the other train.

[0091] In this embodiment, by combining the connection states of the antennas, if both antennas are connected to the left or right side, the number of antennas doubles, the base station BBU performs joint demodulation on the train user's uplink channel, improving uplink demodulation performance. In terms of downlink power, this is equivalent to two RRUs simultaneously covering and transmitting the same area, with a power gain of 3 dB. In addition, coherent JT is performed on the downlink traffic channel, improving beamforming gain, thereby effectively improving the user's uplink and downlink sensing performance.
