[0002] The communication networking method for communication scenarios such as high-speed rail or highways is usually linear chain networking. When deploying communication base stations, the linear chain networking method sets two network RRUs (Remote Radio Units) installed back to back on the same pole. In this way, each RRU is connected to a corresponding antenna panel to achieve communication network transmission in two back-to-back directions.

[0003] In the related art, the coverage and communication perception rate of high-speed users are improved by increasing the number of network RRUs to reduce the distance between two base stations. However, this method has very limited effect on improving the uplink reception and downlink transmission capabilities of high-speed users in the overlapping area of ​​two RRUs. Summary of the invention

The control method includes: determining a mobile vehicle in a communication scenario; and controlling the radio frequency remote units in sequence to provide uplink and downlink network coverage for user terminals on the mobile vehicle according to the running direction of the mobile vehicle and the physical order of multiple radio frequency remote units in the communication networking system.

[0015] Therefore, the embodiment of the present application, when identifying and determining that there is a high-speed mobile vehicle in the communication scenario to which the communication networking system belongs, controls the multiple radio frequency remote units in sequence to provide uplink and downlink network coverage for the user terminal on the mobile vehicle based on the running direction of the mobile vehicle and the physical order of the multiple radio frequency remote units of the communication networking system.

[0016] In this way, compared with the related technology that improves the coverage and communication perception rate of high-speed users by simply increasing the number of network RRUs to reduce the distance between two base stations, the embodiment of the present application can achieve the effect of downlink power sharing and / or doubling the number of transmitting and receiving antennas of the two RF remote units by only identifying whether there is a car and adjusting the antenna switches of adjacent RF remote units in advance according to the physical order of each RF remote unit in the cell when a high-speed mobile vehicle such as a vehicle, high-speed train and airplane is about to enter the network coverage area of ​​a certain RF remote unit, thereby realizing the flexible change of the RF remote unit power with the operation of the mobile vehicle and realizing the purpose of joint demodulation and transmission of uplink and downlink on the network, thereby greatly improving the uplink and downlink perception rates of high-speed users.

[0029] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Reference Figure 1 , Figure 1 This is a schematic diagram of the operating equipment structure of the hardware operating environment involved in the embodiment of the present application.

[0031] In this embodiment, the operating device of the hardware operating environment involved in the embodiment of the present application can be a communication device including a control device of a communication networking system.

[0036] Determine the mobile vehicles in the communication scenario;

[0037] According to the running direction of the mobile vehicle and the physical order of multiple radio remote units in the communication networking system, the radio remote units are controlled in sequence to provide uplink and downlink network coverage for user terminals on the mobile vehicle.

[0038] Exemplarily, the processor 1001 may call a computer program stored in the memory 1005, and further perform the following operations:

[0039] Determining, according to the running direction of the mobile vehicle and the physical order of the multiple radio remote units in the communication networking system, a current radio remote unit among the multiple radio remote units that sequentially provides network services for the user terminal on the mobile vehicle;

[0040] When the mobile vehicle enters the network coverage area of ​​the current radio remote unit, the antenna switch of the next radio remote unit of the current radio remote unit is adjusted to control the current radio remote unit and the next radio remote unit to simultaneously provide uplink and downlink network coverage to the user terminal.

[0041] Exemplarily, the processor 1001 may call a computer program stored in the memory 1005, and further perform the following operations:

[0042] Acquire the number of the user terminals covered by the current radio remote unit;

[0043] When the number exceeds a preset threshold, it is determined that the mobile vehicle has entered the network coverage area of ​​the current radio remote unit.

[0044] Exemplarily, the processor 1001 may call a computer program stored in the memory 1005, and further perform the following operations:

[0045] Acquiring measurement information continuously reported by the user terminal;

[0054] Control multiple radio frequency remote units to provide uplink and downlink network coverage to their respective default network coverage areas at preset times, wherein the preset time is the time when the user terminal reports a channel detection reference signal to the communication networking system, or the preset time is the time when the communication networking system sends system information to the user terminal.

[0055] Based on the operating device structure of the hardware operating environment involved in the above-mentioned embodiment of the present application, the overall concept of the control method of the communication networking system provided by the embodiment of the present application is first proposed.

[0056] The communication networking method for communication scenarios such as high-speed rail or highways is usually linear chain networking. When deploying communication base stations, the linear chain networking method sets two network RRUs (Remote Radio Units) installed back to back on the same pole. In this way, each RRU is connected to a corresponding antenna panel to achieve communication network transmission in two back-to-back directions.

[0057] In the related art, the coverage and communication perception rate of high-speed users are improved by increasing the number of network RRUs to reduce the distance between two base stations. However, this method has very limited effect on improving the uplink reception and downlink transmission capabilities of high-speed users in the overlapping area of ​​two RRUs.

[0058] In response to the above phenomenon, an embodiment of the present application proposes a control method for a communication networking system. When it is identified that there are high-speed mobile vehicles such as high-speed vehicles, high-speed trains or airplanes in the communication scene to which the communication networking system belongs, based on the running direction of the mobile vehicle and the physical order of multiple radio frequency remote units in the communication networking system, the multiple radio frequency remote units are controlled in sequence to provide uplink and downlink network coverage for high-speed users on the mobile vehicle.

[0059] In this way, compared with the related technology that improves the coverage and communication perception rate of high-speed users by only increasing the number of network RRUs to reduce the distance between two base stations, the embodiment of the present application can only identify whether there is a car and adjust the antenna switches of adjacent RF remote units in advance when high-speed mobile vehicles such as vehicles, high-speed trains and airplanes are about to enter the network coverage area of ​​a certain RF remote unit according to the physical order of each RF remote unit in the cell. In this way, the downlink power sharing of the two RF remote units and / or the doubling of the number of transmitting and receiving antennas can be achieved, thereby realizing the flexible change of the RF remote unit power with the operation of the mobile vehicle and realizing the purpose of joint demodulation and transmission of uplink and downlink on the network, thereby greatly improving the uplink and downlink perception rates of high-speed users.

[0060] Based on the overall concept of the control method of the communication networking system provided by the above-mentioned embodiment scheme of the present application, various embodiments of the control method of the communication networking system of the present application are proposed.

[0061] It should be noted that the control method of the communication networking system of the present application is applied to the above-mentioned operating equipment, and the operating equipment can be a communication device including a control device of the communication networking system. Specifically, the communication device can be connected to the communication networking system or integrated into the communication networking system, so as to be able to control the communication networking system. It should be understood that based on different design needs of actual applications, in different feasible embodiments, the control method of the communication networking system of the present application can of course also be applied to other terminal devices. In order to facilitate understanding and explanation of the technical solution, the following text uses the communication device as the execution subject of the solution implementation to explain the control method of the communication networking system of the present application.

[0062] Please refer to Figure 2 , Figure 2This is a schematic diagram of the steps of the first embodiment of the control method of the communication networking system of the present application. It should be noted that although the logical order is shown in the flowchart, in some cases, the control method of the communication networking system of the present application can of course perform the steps shown or described in a different order than here.

[0063] like Figure 2 As shown, in the first embodiment of the control method of the communication networking system of the present application, the control method of the communication networking system provided by the present application may include the following steps:

[0064] Step S10, determining a mobile vehicle in the communication scenario;

[0065] In this embodiment, the communication device determines whether there are high-speed vehicles, high-speed trains, airplanes or other mobile vehicles in the communication scene by identifying high-speed users in the communication scene in which it is located.

[0066] It should be noted that in this embodiment and other feasible embodiments, the communication networking system is a communication networking system (also called a high-speed communication networking system) developed in the field of communication for user groups that are more likely to be mobile, and the communication networking system can provide uplink and downlink network coverage for user groups with mobility (especially high-speed mobile user groups). Exemplarily, the communication networking system can specifically be a linear chain networking system in a high-speed rail scenario or a highway scenario, and the communication equipment can specifically be a device that controls the provision of network coverage for high-speed users in the linear chain networking system, such as a communication base station BBU (Building Base band Unit, indoor baseband processing unit), or the communication equipment can specifically be a device that directly provides network coverage for high-speed users, such as a network radio remote unit RRU.

[0067] In addition, the above-mentioned communication scenarios are communication scenarios where the above-mentioned communication networking system is deployed, such as the above-mentioned high-speed rail scenario, highway scenario, and scenarios where user groups are more likely to be mobile, such as subways and airlines in the communication field. In the communication scenarios where the above-mentioned communication networking system is deployed, the composition of the base station BBU of the communication networking system can be as follows: Figure 3 As shown, that is:

[0068] A base station is equipped with 2 RRUs and 4 antenna panels (specifically, 8T antennas). One RRU is only connected to one antenna panel at a time, and the base station controls which antenna panel each RRU is connected to through a switch. Based on this, the connection between a single RRU on the base station and the antenna panel can be switched in two ways through the switch: one is that the RRU is connected to the left 8T antenna, while the right 8T antenna is disconnected; the other is that the RRU is connected to the right 8T antenna, while the left 8T antenna is disconnected.

[0069] Optionally, corresponding to the communication networking system composed of two RRUs configured for one base station, there are three combinations of connections between the two RRUs of the base station and the antenna panels, namely: the two RRUs are respectively connected to the two antenna panels on the left side of the base station (such as Figure 4a As shown), the two RRUs are connected to the left and right antenna panels of the base station respectively (as shown Figure 4b ), the two RRUs are connected to the two antenna panels on the right side of the base station (such as Figure 4c ).

[0070] Optionally, as shown above Figure 4b The two RRUs shown are respectively connected to an antenna panel on the left and right of the base station, which is the initial default state of the connection between the two RRUs and the antenna panel on the base station in the communication networking system.

[0071] Exemplarily, assuming that the communication device is the above-mentioned base station BBU, then in the following example Figure 5 In the high-speed rail communication scenario shown in the figure, the base station BBU controls the two radio remote units (RRUs) installed on it to provide uplink and downlink network coverage to high-speed users in the current communication scenario. At this time, when the high-speed train is in motion, the base station BBU side continuously monitors the number of high-speed users identified, and when the number meets a certain threshold, it determines that the high-speed train appears in the current communication scenario and identifies the high-speed train as the currently identified high-speed mobile vehicle.

[0072] Step S20, according to the running direction of the mobile vehicle and the physical order of multiple radio remote units in the communication networking system, the radio remote units are controlled in sequence to provide uplink and downlink network coverage for the user terminal on the mobile vehicle.

[0073] In this embodiment, the communication device further determines the running direction of the mobile vehicle at the same time as or after determining that a high-speed mobile vehicle has appeared in the communication scenario. Thus, the communication device can control the multiple radio frequency remote units in sequence according to the running direction and the physical order of the multiple radio frequency remote units in its own communication networking system to provide uplink and downlink network coverage to the user terminal that is also running at high speed on the mobile vehicle.

[0074] It should be noted that in this embodiment and other feasible embodiments, the control method of the communication networking system of the present application uses the networking mode of cell merging through the base station BBU, designs the algorithm of vehicle identification, RRU location positioning and user attribution to obtain the RRU position of the user group distribution, and then adjusts the transmission power and coverage of each antenna device. In this way, the control method of the communication networking system of the present application can, on the one hand, generate a 3db gain by reasonably utilizing the power sharing of the RRU, thereby improving the downlink coverage and downlink performance in communication scenarios such as high-speed rail scenarios, highway scenarios, subways and airplane routes, and on the other hand, by doubling the number of antennas in the same direction of the base station, when the user is in the area of ​​​​the two base stations, the uplink and downlink antennas can be enhanced by 4 times. That is, the control method of the communication networking system of the present application can achieve the purpose of joint balancing and improve the uplink reception performance through uplink joint reception, and can achieve the purpose of coherent JT through multiple RRU downlink joint shaping transmission, and the uplink and downlink can achieve 3-6db gain, thereby effectively improving the user perception in the weak field coverage area.

[0075] Based on this, the above step S20 may include:

[0076] Step S21, determining a current radio remote unit among the multiple radio remote units that sequentially provides network services to a user terminal on the mobile vehicle according to the running direction of the mobile vehicle and the physical order of the multiple radio remote units in the communication networking system;

[0077] In this embodiment, after further identifying and determining the running direction of the high-speed mobile vehicle and the physical order of multiple radio frequency remote units in the communication networking system in which the communication device is located, it can determine, based on the running direction and the physical order, the current radio frequency remote unit that sequentially provides network services to the user terminal on the mobile vehicle during the operation of the mobile vehicle.

[0078] It should be noted that in this embodiment and other feasible embodiments, the communication device can also determine that when the mobile vehicle enters the network coverage of a current remote RF unit among the multiple remote RF units, the mobile vehicle has entered the current remote RF unit at the current moment, so that the current remote RF unit provides network services for the user terminal on the mobile vehicle. Based on this, the communication device can determine each current remote RF unit that the high-speed mobile vehicle enters in turn among the multiple remote RF units.

[0079] Step S22, when the mobile vehicle enters the network coverage area of ​​the current radio frequency remote unit, adjust the antenna switch of the next radio frequency remote unit of the current radio frequency remote unit to control the current radio frequency remote unit and the next radio frequency remote unit to simultaneously provide uplink and downlink network coverage to the user terminal.

[0080] In this embodiment, when the communication device determines that a high-speed mobile vehicle has entered the network coverage of a current remote RF unit among multiple remote RF units, the communication device immediately determines the next remote RF unit adjacent to the current remote RF unit in the running direction according to the running direction of the mobile vehicle in order to improve the perception of the high-speed user of the uplink and downlink network coverage in the entire communication scenario. After that, the communication device adjusts the antenna switch of the next remote RF unit to control the current remote RF unit and the next remote RF unit to simultaneously provide uplink and downlink network coverage for the user terminal on the mobile vehicle.

[0081] It should be noted that in this embodiment and other feasible embodiments, the communication device can determine the physical order of multiple radio remote units (RRUs) in the communication networking system based on the measured signal strength changes of the high-speed user terminal. Therefore, when a high-speed vehicle or other mobile vehicle is about to enter a certain RRU, the adjacent RRU is informed in advance to adjust the antenna, so as to achieve the effect of sharing the downlink power of the two RRUs and doubling the number of transmitting and receiving antennas, thereby achieving the purpose of joint uplink and downlink demodulation and transmission, and effectively improving the uplink and downlink perceived rate of users for network services in high-speed communication scenarios.

[0082] For example, Figure 6 As shown, when the communication device is used as a base station BBU in a communication networking system, if the base station BBU recognizes that a high-speed mobile vehicle enters the current radio remote unit RRU1, the base station BBU will connect the next radio remote unit RRU2 adjacent to the RRU1 in the running direction to the antenna on the right side of the base station according to the pre-learned physical order of multiple RRUs in the communication networking system RRU1-RRU2-RRU3-RRU4-RRU5-RRU6 and the running direction of the mobile vehicle. When determining that the mobile vehicle enters the network coverage of RRU1, the base station BBU needs to connect the next radio remote unit RRU2 adjacent to the RRU1 in the running direction to the antenna on the right side of the base station, so that the RRU2 and RRU1 can simultaneously improve the network uplink and downlink services for the user terminal on the mobile vehicle in the same direction. In this way, for the user terminal on the high-speed mobile vehicle, it is equivalent to doubling the antennas providing network uplink and downlink services, and the downlink power is also increased by 3db.

[0083] Optionally, for the original coverage area of ​​the next radio remote unit RRU2, the communication device as the base station BBU will switch the RRU2 to the antenna connected to the left side of the base station only at the SRS moment (the moment when the user terminal reports the channel sounding reference signal to the communication networking system). At this time, the antenna connection state of the i-th radio remote unit RRU1 can remain unchanged, so that the uplink and downlink network data of the user terminal are jointly received and sent by the two RRUs.

[0084] Based on this, in this embodiment and other feasible embodiments, the control method of the communication networking system of the present application may further include the following steps:

[0085] Step S30, controlling the plurality of radio frequency remote units to provide uplink and downlink network coverage to their respective default network coverage areas at preset times, wherein the preset time is the time when the user terminal reports a channel detection reference signal to the communication networking system, or the preset time is the time when the communication networking system sends system information to the user terminal.

[0086] In this embodiment, when the communication device sequentially controls the radio frequency remote units to provide uplink and downlink network coverage to the user terminal on the high-speed mobile vehicle, once it detects that the current moment has arrived when the user terminal reports the channel detection reference signal to the communication networking system, or the current moment has arrived when the communication networking system sends system information to the user terminal, the communication device controls one or more of the multiple radio frequency remote units to provide uplink and downlink network coverage to their respective default network coverage areas.

[0087] It should be noted that, in this embodiment and other feasible embodiments, the default network coverage area of ​​the control radio remote unit is the connection state between the control radio remote unit and the antenna panel on the base station, which is as described above. Figure 4b In the initial default state shown, the network coverage area when the radio remote unit provides uplink and downlink network services.

[0088] For example, assuming that the communication networking system in which the communication device is located adopts a cell-merging networking mode, the communication device can be connected to multiple radio remote units RRU when acting as a base station BBU, and the communication networking system can use a common Cell ID and its related public channels. The initial state of the antenna connected to each radio remote unit RRU and the antenna panel is: the RRU on one side of the base station is connected to an antenna panel on its own side (such as Figure 4b At this time, since the antenna panels on both sides of the base station are facing each side, the left and right sides of the base station will have uplink and downlink network coverage. Figure 7As shown, if a user terminal in a high-speed mobile vehicle appears, the user terminal only receives the signal from the antenna connected to one of the RRUs, and the uplink and downlink services are also independently received and sent by the RRU.

[0089] In addition, the communication device as the base station BBU also configures the same SRS resources for N radio remote units RRUs in a high-speed cell, so that at the periodic time point of the SRS configuration, the base station BBU switches the connection status between each RRU and the antenna to Figure 4b The initial default state shown, and then immediately after the SRS time point, the connection state between each RRU and the antenna is switched back to the connection state before this SRS time point. For example, in a 5ms frame structure, 4 SRS symbols are configured on the Sslot. When the base station BBU controls the connection state between RRU1 and RRU2 and the antenna so that both RRU1 and RRU2 are connected to the antenna panel on the left side of the base station, at the start time of the first SRS symbol, the base station BBU needs to adjust the connection state between RRU2 and the antenna to the point where RRU2 is connected to the antenna panel on the right side of the base station, while the connection state between RRU1 and the antenna remains unchanged. At this time, the connection states between RRU1 and RRU2 and the antenna are both in the initial default state. After the 4 SRS symbols are sent, the connection state between RRU1 and the antenna remains unchanged, while the connection state between RRU2 and the antenna is immediately switched back to the original state of being connected to the antenna on the left side of the base station by the base station BBU control.

[0090] In this embodiment, the communication device determines whether a high-speed mobile vehicle appears in the communication scene by identifying the user terminal in the high-speed communication scene in which it is located. While or after determining that a high-speed mobile vehicle appears in the communication scene, the communication device further determines the running direction of the mobile vehicle, so that the communication device can control the multiple radio remote units in sequence to provide uplink and downlink network coverage for the high-speed users on the mobile vehicle according to the running direction of the mobile vehicle and the physical order of the multiple radio remote units in the communication networking system in which it is located.

[0091] In this way, compared with the related technology that only increases the number of network RRUs to reduce the distance between two base stations to improve the network coverage and communication perception rate of user terminals in high-speed communication scenarios, the embodiments of the present application can only identify whether there is a car and adjust the antenna switches of adjacent RF remote units in advance when high-speed mobile vehicles such as vehicles, high-speed trains and airplanes are about to enter the network coverage of a certain RF remote unit according to the physical order of each RF remote unit in the cell. In this way, the downlink power sharing of the two RF remote units and / or the doubling of the number of transmitting and receiving antennas can be achieved, thereby realizing the flexible change of the RF remote unit power with the operation of the mobile vehicle and realizing the purpose of joint uplink and downlink demodulation and transmission on the network, thereby greatly improving the uplink and downlink perception rates of high-speed users.

[0092] Furthermore, based on the above-mentioned first embodiment of the control method of the communication networking system of the present application, a second embodiment of the control method of the communication networking system of the present application is proposed.

[0093] In the second embodiment of the control method of the communication networking system of the present application, the control method of the communication networking system of the present application may further include the following steps:

[0094] Step S40, obtaining the number of user terminals covered by the current radio remote unit;

[0095] Step S50: When the number exceeds a preset threshold, it is determined that the mobile vehicle has entered the network coverage area of ​​the current radio remote unit.

[0096] In this embodiment, when the communication device determines whether a high-speed mobile vehicle enters the network coverage of a current radio frequency remote unit among multiple radio frequency remote units, it can adopt the same principle as the method of identifying and determining whether there is an oncoming vehicle in the communication scenario, so as to obtain the number of user terminals on the mobile vehicle covered by the current radio frequency remote unit, and detect in real time whether the number exceeds a preset threshold value, so as to determine that the mobile vehicle has entered the uplink and downlink network coverage area of ​​the current radio frequency remote unit at the current moment when the number exceeds the preset threshold value.

[0097] It should be noted that in this embodiment and other feasible embodiments, the preset threshold value can be specifically set to 200, 500, and 800, etc. It should be understood that, since the number of user groups carried by mobile vehicles such as high-speed vehicles, high-speed railways, subways, or airplanes is different in different high-speed communication scenarios, the preset threshold value can be flexibly set based on different design needs of actual applications, that is, the control method of the communication networking system of the present application does not limit the size of the preset threshold value.

[0098] For example, Figure 8 As shown, assuming that the communication device is a base station BBU in a communication networking system, then in the high-speed communication scenario where the base station BBU is located, that is, the high-speed rail scenario, if a high-speed mobile vehicle is about to enter cell 2, the base station BBU of the cell will determine whether the mobile vehicle enters the RRU1 based on whether the number of user terminals covered by RRU1 in cell 2 meets a certain threshold.

[0099] In addition, after determining that a high-speed mobile vehicle enters RRU1 in cell 2, the base station BBU can also switch the source cell, cell 1, according to the mobile vehicle to obtain the running direction of the mobile vehicle, that is, the train is going to exit cell 1 and enter cell 2. At this time, the base station BBU in cell 1 can receive the exit mark, and the base station BBU in cell 3 adjacent to cell 2 will receive the entry mark of the train.

[0100] Furthermore, if the base station BBU detects that the number of user terminals covered by RRU1 in cell 2 does not meet the conditions (does not exceed the above threshold), the base station BBU also needs to check whether there are other states that have been transmitted (such as the above-mentioned vehicle exit mark or vehicle entry mark). If so, maintain the original state, otherwise it is a no-vehicle state.

[0101] Optionally, the control method of the communication networking system of the present application may further include the following steps:

[0102] Step S60, obtaining measurement information continuously reported by the user terminal;

[0103] Step S70, determining a plurality of target radio remote units having the strongest signals among the plurality of radio remote units according to the measurement information;

[0104] Step S80: determining the physical order of the plurality of radio remote units according to the continuous change pattern of the target radio remote unit.

[0105] In this embodiment, when learning the physical order of multiple remote radio frequency units in the communication networking system in which the communication device is located, it continuously obtains the measurement information continuously reported by the user terminal to the communication networking system, and then the communication device can determine the multiple target remote radio frequency units with the strongest signals among the multiple remote radio frequency units according to the measurement information continuously reported by the terminal device. Therefore, after generating the multiple target remote radio frequency units through a continuous change pattern, the communication device can learn and determine the physical order of the multiple remote radio frequency units in the entire communication networking system based on the continuously changing image.

[0106] Exemplarily, when the communication device is used as a base station BBU in a communication networking system, the base station BBU receives SRS measurement information continuously reported by user terminals on high-speed mobile vehicles, thereby identifying the connection direction of each AAU based on the SRS measurement information. The user terminal on the mobile vehicle will receive the measurement information of each RRU in a cell, and then select the target RRU with the strongest signal among the current multiple RRUs according to the size of the measurement value in the RRU measurement information. After that, the base station BBU can obtain the physical order bitmap of multiple RRUs in the entire cell by maintaining the change pattern of the target RRU with the strongest signal reported by each high-speed user.

[0107] Furthermore, based on the above-mentioned first embodiment and / or second embodiment of the control method of the communication networking system of the present application, a third embodiment of the control method of the communication networking system of the present application is proposed.

[0108] In the third embodiment of the control method of the communication networking system of the present application, the above-mentioned step S22 of "adjusting the antenna switch of the next radio remote unit" may include:

[0109] Step S221, when there is no opposite vehicle in the default network coverage area of ​​the next remote radio unit, adjusting 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;

[0110] Wherein, the running direction of the mobile vehicle is opposite to the running direction of the opposite vehicle.

[0111] In this embodiment, when the communication device adjusts the connection state between the next remote RF unit and the antenna, it first determines whether there is an opposite vehicle of the mobile vehicle that has been determined to enter the network coverage area of ​​the current remote RF unit within the default network coverage area of ​​the next remote RF unit. Therefore, the communication device starts to adjust the antenna switch of the next remote RF unit only when it is determined that there is no opposite vehicle within the default network coverage area of ​​the next remote RF unit, so as to connect the next remote RF unit with the antenna panel on the same side of the current remote RF unit, thereby controlling the current remote RF unit and the next remote RF unit, and at the same time providing uplink and downlink network coverage for the user terminal on the mobile vehicle that has entered the network coverage area of ​​the current remote RF unit.

[0112] Optionally, when the communication device detects that there is an oncoming mobile vehicle within the default network coverage area of ​​the next radio frequency remote unit, even if the high-speed mobile vehicle has entered the network coverage area of ​​the current radio frequency remote unit, the communication device will not adjust the antenna switch of the next radio frequency remote unit. This is to ensure that the user terminal on the oncoming mobile vehicle can at least obtain the uplink and downlink network services provided by the next radio frequency remote unit.

[0113] Optionally, the antenna panel on the same side of the current radio remote unit includes: a first antenna panel and a second antenna panel. Based on this, the step of "adjusting the antenna switch of the next radio remote unit so that the next radio remote unit is connected to the antenna panel on the same side of the current radio remote unit" may include:

[0114] When the current remote radio frequency unit is connected to the first antenna panel, the antenna switch of the next remote radio frequency unit is adjusted to connect the (i+1)th remote radio frequency unit to the first antenna panel or the second antenna panel.

[0115] In this embodiment, when the communication device determines that there is no opposite vehicle within the default network coverage area of ​​the next RF remote unit, and thus adjusts the antenna switch of the next RF remote unit, if there are two antenna panels on the same side of the current RF remote unit, i.e., the first antenna panel and the second antenna panel, and the current RF remote unit is already connected to the first antenna panel, the communication device can adjust the antenna switch of the next RF remote unit so that the next RF remote unit is also connected to the first antenna panel, or adjust the antenna switch of the next RF remote unit so that the next RF remote unit is connected to the second antenna panel.

[0116] Optionally, if there is only one antenna panel on the same side of the current RF remote unit, and the one antenna panel is already connected to the current RF remote unit, the communication device may also adjust the antenna switch of the next RF remote unit to connect the next RF remote unit to the first antenna panel, that is, the first antenna panel is now connected to both the current RF remote unit and the next RF remote unit adjacent to the current RF remote unit.

[0117] It should be noted that in this embodiment and other feasible embodiments, if only one antenna panel is configured on each side of the base station, when a high-speed user is on one side, the base station BBU can also be used to control the remote radio units RRU on both sides of the base station to be connected to the antenna panel on one side of the base station to achieve the superposition of the power of the two remote radio units RRU. At this time, there is still a 3db gain in the downlink. Only one antenna panel is configured on each side of the base station, and the connection status between the remote radio unit RRU and the antenna panel can be as follows: Figure 9a , Figure 9b and Fig.9c shown.

[0118] Alternatively, if Fig.10 As shown, a preferred embodiment of the control method of the communication networking system of the present application is proposed. In this embodiment, the control method of the communication networking system of the present application may include the following steps:

[0119] 1: A base station BBU in a cell is connected to multiple radio remote units RRU. The cell uses the same CellID and its related public channels. The connection status between each radio remote unit RRU and the antenna is the initial default status, such as Figure 4b As shown in the figure, the RRU on one side of the base station is connected to an antenna panel on its own side. At this time, the antennas on both sides of the base station are facing each side, and both sides have uplink and downlink network coverage. Figure 7 As shown in the figure, if a user enters the coverage area of ​​an RRU on one side of the base station, the user's terminal device will only receive the signal of the antenna connected to one of the RRUs, and the uplink and downlink services are also received and sent independently by the RRU;

[0120] 2: The communication device as a base station BBU also configures the same SRS resources for N radio remote units RRUs in a high-speed cell, so that at the periodic time point of the SRS configuration, the base station BBU switches the connection status between each RRU and the antenna to the following: Figure 4bThe initial default state shown, and then after the SRS time point, the connection state between each RRU and the antenna is immediately switched back to the connection state before this SRS time point. For example, in a 5ms frame structure, 4 SRS symbols are configured on the Sslot. When the base station BBU controls the connection state between RRU1 and RRU2 and the antenna so that both RRU1 and RRU2 are connected to the antenna panel on the left side 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 to the point where RRU2 is connected to the antenna panel on the right side of the base station, while the connection state between RRU1 and the antenna remains unchanged. At this time, the connection states between RRU1 and RRU2 and the antenna are both in the initial default state. After the 4 SRS symbols are sent, the connection state between RRU1 and the antenna remains unchanged, while the connection state between RRU2 and the antenna is immediately switched back to the original state of being connected to the antenna on the left side of the base station by the control of the base station BBU;

[0121] 3: When the train is in motion, the base station BBU determines whether there is a high-speed moving vehicle - a train - based on whether the number of high-speed users meets a certain threshold. That is, if the number of high-speed users meets the threshold, it is identified as an incoming train. At the same time, the running direction of the train is obtained based on the switching source cell of the high-speed users, and the running direction is passed to the next adjacent high-speed cell. Figure 8 As shown in the figure, when the train is about to enter cell 2, the base station BBU of the cell determines whether the train is coming based on whether the number of high-speed users meets a certain threshold. If the condition is met, it means that the train is coming. At the same time, the direction of the train is obtained based on the source cell of the switching user, that is, the train is about to leave cell 1, and the exit identifier is passed to the base station BBU of cell 1, and the identifier of the incoming train is passed to the base station BBU of cell 3, another neighboring cell of cell 2. On the contrary, if the number of high-speed users does not meet the condition, it is necessary to check whether there are other states that have been transmitted. If so, keep the original state, otherwise it is a no-car state.

[0122] 4: The base station BBU identifies the connection direction of each AAU based on the measurement information of the high-speed user SRS. The high-speed user in the cell will receive the measurement of each RRU in the cell, and then select the RRU with the strongest current signal based on the size of the measurement value, and by maintaining the strongest RRU change pattern of each high-speed user, the physical order bitmap of the RRU in the cell is obtained;

[0123] 5: After receiving the vehicle identification, the BBU determines the RRU location to which the high-speed user belongs at the current moment based on the measurement information continuously reported by the high-speed user's terminal device UE, selects the current switch state, and notifies the RRU to control the antenna switch, thereby determining the connection relationship between the RRU and the antenna. According to the RRU with the strongest signal maintained in 4, the total number of users covered by each RRU is counted in a sliding window manner, and the top N statistical windows of this cell are calculated at each moment. If the number of users of a certain RRU is UeNum_RRU j If the ratio of the total number of RRU users exceeds a certain threshold, then according to the relationship between the train's running direction and the physical sequence bitmap of the RRU obtained in 3 and 4, the base station BBU notifies another RRU on the pole to switch the switch state to change the connection state with the antenna. At the same time, it can also notify the next RRU to adjust the state or notify the next cell to adjust the state.

[0124]

[0125] In the above formula, j represents cell j, N is the Nth terminal device Ue in cell j, and i represents the i-th terminal device Ue in cell j.

[0126] If the user ratio of adjacent RRUs between two different poles (base stations) is higher than the threshold, the base station BBU will notify the other RRU on the two poles to switch the switch state to change the connection state with the antenna. At the same time, it can also notify the next RRU to adjust the state or notify the next cell to adjust the state. The detailed switch state changes are as follows:

[0127] 501: If Fig.11 As shown in the figure, in the future vehicle, each RRU is connected to the antenna as follows Figure 4b The initial default state shown is cell beam coverage and independent uplink and downlink transmission;

[0128] 502: If Fig.12As shown, after the train enters RRU1, the base station BBU identifies it as an incoming train. Based on the location information of each RRU learned in 4 (the order of RRUs is RRU1-RRU2-RRU3-RRU4-RRU5-RRU6) and the direction of the incoming train, when the user ratio of RRU1 reaches the threshold, it controls the connection between RRU2 and the antenna to switch RRU2 to the antenna on the right side of the base station, thereby improving the uplink and downlink services for high-speed users in the same direction together with RRU1. At this time, the user terminals on the train are equivalent to doubling the uplink and downlink antennas, and the downlink power is also increased by 3db. For the original coverage area of ​​RRU2, only at the SRS moment does the base station BBU control the connection between RRU2 and the antenna to switch to the connection between RRU2 and the antenna on the left side of the base station. The antenna connection status of RRU1 remains unchanged, and the uplink and downlink of users are jointly received and sent by two RRUs;

[0129] 503: If Fig.13 As shown in the figure, as the train moves, some users begin to enter RRU2. Since RRU1 and RRU2 are on the same base station, the number of users of RRU1 or RRU2 does not meet the ratio. At this time, the base station BBU needs to control the connection between RRU2 and the antenna to switch to the initial default state, that is, adjust RRU2 to the antenna on the left side of the base station, and the antenna connected to RRU1 remains unchanged.

[0130] 504: If Fig.14 As shown in the figure, as the train moves, the train enters the user satisfaction ratio of RRU2. At this time, the base station BBU needs to control RRU1 to switch the connection with the antenna to the state of connecting with the antenna on the left side of the base station, and RRU2 remains unchanged. At the same time, the base station BBU also determines the next adjacent RRU3 and RRU4 according to the physical sequence bitmap of the RRU obtained in step 4, so as to control RRU4 to switch the connection with the antenna to the antenna on the side where RRU3 is located, and the antenna connection of RRU3 remains unchanged. In this way, the user has both the 3db power of RRU1 and the 3db power gain of RRU4. At the same time, the uplink can achieve joint reception of 4 RRUs, and the downlink can achieve joint transmission of 4 RRUs.

[0131] 505: As Fig.15 As shown, as the train moves, the train enters RRU3. Although the users of RRU1 or RRU2 do not meet the ratio at this time, RRU2 and RRU3 are not on the same pole, and the user ratio of RRU2 and RRU3 meets the threshold. At this time, the base station BBU needs to maintain the connection status of each RRU and the antenna according to the same process as 504.

[0132] 506: As the train moves, in cell 1, the train passes RRU4 / RRU5, and the processing flow is the same as 501 to 505 above. When the train reaches RRU6, the antenna of RRU5 in cell 1 is connected to the left side. At this time, the base station BBU determines that the train is about to enter cell 2 according to the direction of the incoming train. Therefore, if there is no other train in cell 2 at this time, for RRU2 in cell 2, the base station BBU will control the RRU2 to connect to the antenna on the right side of the base station (such as Fig.16 ). If there are other trains in cell 2, train 2 enters RRU2 at this time, and will enter RRU1 at the next moment. At this time, the base station BBU will not be able to adjust the connection between RRU1 or RRU2 of cell 2 and the antenna, that is, at this time, RRU1 and RRU2 of cell 2 each maintain the initial default state of connection with the antenna (such as Fig.17 ), otherwise, there will be relatively large gaps in the coverage for the other trains.

[0133] In this embodiment, combined with the connection status of the antenna, if the connection status of the two antennas are both on the left or right side, the number of antennas is doubled, and the base station BBU jointly demodulates the uplink channel of the train user to improve the uplink demodulation performance. The downlink power is equivalent to the same coverage of two RRUs, with a power gain of 3db. At the same time, coherent JT is performed on the downlink service channel to improve the shaping gain, thereby effectively improving the user's uplink and downlink perception performance.
