[0019] 100 - communication device; 101 - processing unit; 102 - local antenna unit; 1021 - first antenna subunit; 1022 - second antenna subunit; 1023 - third antenna subunit; 103 - control unit. DETAILED DESCRIPTION
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.
[0021] like Figure 1 As shown, the utility model provides a communication device 100, including: a processing unit 101, an antenna unit 102 and a control unit 103. The antenna unit 102 includes: a first antenna subunit 1021, a second antenna subunit 1022 and a third antenna subunit 1023.
[0022] The processing unit 101 is a unit for processing the communication device 100 in two modes: data communication and / or local service processing. The processing unit 101 is connected to the antenna unit 102 and the control unit 103, and the control unit 103 controls the processing unit 101 and the antenna unit 102 to be in various configurations.
[0023] The antenna unit 102 includes: a first antenna subunit 1021 , a second antenna subunit 1022 and a third antenna subunit 1023 .
[0024] Among them, the first antenna unit 1021 is suitable for realizing the first coverage range of the local antenna, and the local antenna is a built-in antenna of the communication device, which can realize the function of local network coverage in a small range. Generally speaking, a typical macro cell coverage range is about 1 to 3 kilometers, and the coverage range of a micro cell may be about several hundred meters to 1 kilometer. However, these values are not fixed, and the actual coverage range may vary according to specific conditions such as the base station's transmission power, antenna type, antenna gain, terrain, building height and distribution.
[0025] Among them, the second antenna unit 1022 is that as the communication coverage demand and capacity increase, the first coverage range of the local antenna cannot meet the demand, so the processing unit of the second antenna subunit will be connected to the cable extension unit to complete the transmission and reception of RF signals within the second coverage range. The specific coverage range of the second coverage range may vary for different devices and specific scenarios, and can generally be extended to more than 1 km. It is noted that the cable unit and the processing unit can be connected using a cable.
[0026] When the processing unit and the cable extension unit are connected, a power splitter can be added. A single antenna can achieve two-way extension through the power splitter. However, this communication device has a maximum of two antennas and supports four-way extension.
[0027] Among them, the third antenna subunit 1023 is further connected to the processing unit via the radio frequency remote unit as the communication coverage demand and capacity increase, and the second coverage range can no longer meet the demand, and the communication radio frequency signal is sent and received within the third coverage range. The third coverage range is applied to some special occasions, such as highways and high-speed railways, in which case it can be extended to four or five kilometers. The specific coverage range will vary according to the actual scenario, so other factors such as equipment performance and environmental conditions need to be considered in actual use.
[0028] The communication mode within the third coverage area is remote antenna extension, and the remote antenna extension needs to be connected to the radio remote unit (Radio Remote Unit, RRU). The processing unit of this communication device realizes the functions of part of the indoor baseband processing unit (Building Base band Unite, BBU) or all BBU and the complete protocol stack.
[0029] Optical fiber transmission is generally used between BBU and RRU, and RRU is connected to the antenna through coaxial cable and power divider, that is, the trunk uses optical fiber and the branch uses coaxial cable, so the processing unit of the third antenna subunit and RRU can also be connected through the trunk optical fiber and the branch coaxial cable. The interface between the processing unit of the third antenna subunit and the RRU optical fiber connection is an open universal public wireless interface, which can stably connect with the equipment of mainstream manufacturers.
[0030] At the same time, the BBU and the RRU can also be connected by a twisted pair network cable, so the processing unit of the third antenna subunit and the RRU can also be connected by a twisted pair network cable.
[0031] Among them, the connection segmentation method with the RRU can be a variety of segmentation modes. Through intelligent settings, the segmentation method can be distributed according to network coverage requirements.
[0032] Among them, the connection mode between the processing unit of the third antenna subunit and the RRU can be star-shaped or chain-shaped, which can better expand the remote network coverage range and the remote network coverage distance. The star connection is a direct connection between a BBU and multiple RRUs, and multiple RRUs can be understood as connected to the BBU in parallel. The chain connection is a connection between a BBU and an RRU, and this connected RRU is then connected to multiple RRUs in sequence, and multiple RRUs can be understood as a series connection.
[0033] The control unit 103 is a core unit that controls the processing unit 101 in data communication and / or local service processing and the antenna unit 102. It can further adjust the communication or processing configuration of the entire communication device according to the requirements of some indoor scenes, so as to meet the requirements of large capacity and high coverage of some indoor scenes. In general, the control unit 103 can adjust different configurations according to the different requirements of data communication and local services according to the pre-set multiple configurations, so as to meet the requirements of different network coverage and capacity.
[0034] At the same time, in the utility model, the connection between the processing unit of the third antenna subunit and the BBU utilizes a unique multi-channel algorithm to achieve spatial isolation, which can reduce interference, and the coverage and capacity can be planned independently; the dependence on trunk amplifiers is reduced, the baseband capacity can be shared, and the expansion capacity is large; at the same time, the optical fiber is lossless, the trunk is easy to deploy, and the RRU deployment is flexible.
[0035] For further information, see Figure 2 , the figure shows 6 specific configurations of the control unit controlling the processing unit in communication and / or local business processing and the antenna unit. Note that the order of configuration changes accordingly as the demand for network coverage and capacity increases. Among them, the 6 specific configurations are as follows:
[0036] Among them, configuration 1 is that the control unit controls the processing unit to perform data communication processing and local business processing based on communication and local business requirements, and controls the first antenna subunit to perform transmission and reception of communication radio frequency signals in one or more cells within the first coverage range.
[0037] Specifically, the local antenna performs local service processing while being in the first coverage mode. The local service processing includes local service identification and local processing, and can realize the function of local acceleration. The local cell coverage may include one or more cells.
[0038] Configuration 2 is that the control unit controls the processing unit to perform data communication processing and local business processing based on communication and local business requirements, and controls the second antenna subunit to perform transmission and reception of communication radio frequency signals in one or more cells within the second coverage area.
[0039] Specifically, the mode of antenna extension is that the first coverage range of the local antenna can no longer meet the demand, so the cable unit and the processing unit of the second antenna subunit are connected to complete the antenna extension. Note that the function of local business processing can still be realized under configuration 2. The connection of the second antenna subunit in the second coverage range can be one or more cells.
[0040] Configuration 3 is that the control unit controls the processing unit to perform data communication processing based on communication and local business requirements, and controls the first antenna subunit to perform the transmission and reception of the communication radio frequency signal in one or more cells within the first coverage area.
[0041] Specifically, configuration 3 is a mode in which the local antenna is in the first coverage range of multiple cells. Note that the multiple cell mode is not sufficient to support the function of local business processing.
[0042] Configuration 4 is to control the processing unit to perform data communication processing, and control the first antenna subunit to perform transmission and reception of communication radio frequency signals in one or more cells within the first coverage range, and control the second antenna subunit to perform transmission and reception of communication radio frequency signals in one or more cells within the second coverage range.
[0043] Specifically, configuration 4 is also a multi-cell mode, which is not enough to support the local acceleration service. This is because the multi-cell first coverage range of the local antenna can no longer meet the demand, which will cause the processing unit and cable unit of the second antenna subunit of any one or more cells to be connected to complete the antenna extension function.
[0044] Configuration 5 is a control unit that controls the processing unit to perform data communication processing based on communication and local business needs, and controls the first antenna subunit to perform the transmission and reception of the communication radio frequency signal in one or more cells within the first coverage range, and controls the third antenna subunit to perform the transmission and reception of the communication radio frequency signal in one or more cells within the third coverage range.
[0045] Specifically, in the remote antenna extension mode, any one or more cells are selected in the multi-cell to connect the processing unit of the third antenna subunit to the RRU, wherein the connection with the RRU is an optical fiber or a twisted pair network cable. Configuration 5 is to connect the RRU through the processing unit of the third antenna subunit, that is, the connection method of the BBU and the RRU is a star connection. That is, one BBU is directly connected to multiple RRUs. That is, multiple RRUs can be understood as a parallel connection. The interface segmentation method of connecting the third antenna subunit and the RRU of BBU configuration 5 can be selected for multiple segmentation. For example: option7-1, option7-2, option8 and other segmentation methods.
[0046] Configuration 6 is also a control unit that controls the processing unit to perform data communication processing based on communication and local business needs, and controls the first antenna subunit to perform the transmission and reception of the communication radio frequency signal in one or more cells within the first coverage range, and controls the third antenna subunit to perform the transmission and reception of the communication radio frequency signal in one or more cells within the third coverage range.
[0047] Specifically, in the remote pull-out mode, any one or more cells are selected in the multi-cell to connect the processing unit of the third antenna subunit to the RRU, wherein the connection with the RRU is an optical fiber or a twisted pair network cable. Configuration 6 connects the RRU through the processing unit of the third antenna subunit, that is, the connection between the BBU and the RRU is a chain connection. That is, a BBU is connected to an RRU, and this connected RRU is then connected to multiple RRUs, and multiple RRUs can be understood as being connected in series. The interface segmentation method between the third antenna subunit and the RRU of configuration 6 can be selected from a variety of options. For example: option 7-1, option 7-2, option 8 and other segmentation methods.
[0048] It should be noted that both configuration 5 and configuration 6 use the remote RRU method to expand network coverage and capacity. In this way, for the downlink direction: the optical fiber is directly connected from the BBU to the RRU, and the baseband digital signal is transmitted between the BBU and the RRU, so that the communication device can control the signal of a certain user to be transmitted from the designated RRU channel, which can greatly reduce the interference to users on other channels in the cell. For the uplink direction: the user's mobile phone signal is received by the nearest channel, and then transmitted from this channel to the communication device through the optical fiber, which can also greatly reduce the interference between users on different channels. The BBU+RRU solution is very flexible in capacity configuration. According to capacity requirements, the BBU can be configured to support the expansion of each channel from 1 / 6 carrier to 3 carriers without changing the RRU and indoor distribution system.
[0049] Further, please refer to Table 1 below, which shows the specific values displayed by the control unit.
[0050]
[0051]
[0052] Table 1
[0053] Among them, the specific values in Table 1 are as follows:
[0054] In the present invention, the communication device controls the processing unit and the antenna unit through the control unit to realize the conversion of 6 configuration modes according to the enhancement of indoor network coverage and capacity. However, the accurate configuration takes into account factors such as whether the antenna is pulled far away and the selected segmentation method, so the configuration of the control unit is finally displayed as 7 digits.
[0055] First, the first three digits represent configurations 1 to 6, that is, 001 is configuration 0, 001 is configuration 1 for the normal cell mode, 010 is configuration 2 for the cell antenna remote mode, 011 is configuration 3 for the normal multi-cell mode, 100 is configuration 4 for the multi-cell antenna remote mode, 101 is configuration 5 for the multi-cell remote antenna remote mode, and 110 is configuration 6 for the multi-cell remote antenna remote mode.
[0056] Then the last 4 digits of configuration 1-4 show the number of remote antennas, that is, 0000 means no remote antenna, 0001 means one remote antenna, 0010 means two remote antennas, 0011 means three remote antennas, and 0100 means four remote antennas. Configuration 1-4 thus constitutes the final 7-digit configuration.
[0057] The fourth digit of configuration 5 and 6 indicates the number of connected RRUs, that is, 0 indicates one RRU is connected, and 1 indicates two RRUs are connected. The last three digits of configuration 5 and 6 indicate the antenna segmentation method, that is, 000 indicates no antenna segmentation, 001 indicates the segmentation method selected is option 7-1, 010 indicates the segmentation method selected is option 7-2, and 100 indicates the segmentation method selected is option 8.
[0058] In this way, the control unit of the communication device controls the processing unit and the antenna unit to change different modes under multiple configurations to achieve different network coverage and capacity requirements.
[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
