The broadband access method provided by the embodiment of the application is applied to the broadband access hardware implementation of the communication network shown in fig. 1. In the prior art, the "last mile" in communication refers to the transmission line from the service provider's equipment room switch to the user's computer or other terminal equipment. Currently, each large operator adopts a mode of fiber to the home (fiber to the home, FTTH), namely, deploying the optical fiber broadband directly into a user cell and accessing the user home, so as to solve the problem of the last kilometer. The above-described fiber optic cable-to-home solution suffers from many drawbacks for operators due to the hardware limitations of fiber deployment into cells.
The embodiment of the application fully utilizes the 5G large bandwidth technology and the 5G CPE to realize the capability of converting 5G signals into WIFI, and provides an innovative solution for the last kilometer of home hundred megalevel broadband service access aiming at difficult optical fiber access scenes, scenes with lower optical fiber access benefits and scenes needing to rapidly open home broadband service.
Accordingly, an embodiment of the present application provides a broadband access method, as shown in fig. 2, which may include S201 to S204:
s201, determining antenna parameters of the base station according to the positions and the sizes of the base station and the target building.
The base station may be a base station in fig. 1, where the target building is located in a coverage area of the base station, and the target building is a building where a home of a target user to be connected to the broadband is located.
Illustratively, the target user is a mobile network high average revenue per user (average revenue per user, ARPU) value user of an operator, for which the operator plans to open and access hundred mega-level broadband services for the home, for increasing the user's viscosity and improving the user's ARPU value. Because the residential cell where the target user's home is located does not deploy optical fiber resources, an innovative solution of "5G base station+5G CPE" is adopted.
Optionally, before step S201, an operation of selecting a 5G base station, that is, selecting a base station with the best signal quality and highest signal strength in the target building from the base stations providing 5G signal coverage for the target building as a base station accessing the broadband network may be further included.
Alternatively, the target building may be a building where the target user family is located, or may be a row of buildings where the target user family is located, where the present application is not limited herein.
In the 5G scene, mechanical parameters which can be adjusted by the Massive MIMO antenna include a mechanical downward inclination angle, a mechanical azimuth angle and the like, and electrical parameters include a horizontal wave width, a vertical wave width and the like, and through adjusting the parameters, the perception of a target user is ensured, so that a base station provides better signal coverage for a target building.
In one possible implementation, as shown in fig. 3, the antenna parameters of the base station are determined by:
step one: and determining the mechanical azimuth angle of the base station antenna according to the central longitude and latitude of the target building and the longitude and latitude of the base station.
Fig. 4 shows a top view of a base station and a target building in the broadband access method according to the embodiment of the present application. As shown in fig. 4, the azimuth angle of a base station antenna can be understood as the angle that a plane in the north direction rotates clockwise to coincide with the plane in which the antenna is located. The mechanical azimuth angle of the base station antenna is realized by calculating a determined theoretical value and adjusting the physical direction of the antenna, but has a certain deviation from the actual optimal azimuth angle.
In order to avoid inter-cell interference, and effectively utilize the cell resources of the base station, the azimuth angle of the base station antenna is adjusted so that the main coverage area of a certain sector of the base station corresponds to a target building, and the plane of the base station antenna is in the same plane as the center of the target building. Thus, the mechanical azimuth a of the base station antenna is compared with the center longitude and latitude (x) 1 ，y 1 ) Longitude and latitude (x) 0 ，y 0 ) The following formula is satisfied:
step two: and calculating the horizontal lobe width of the base station antenna according to the distance between the target building and the base station.
The angle between the two points at which the power gain drops by 3dB relative to the maximum point of the main lobe in the horizontal plane pattern of the antenna is defined as the horizontal lobe width of the antenna, also called horizontal beam width or horizontal lobe angle. Most of the energy of the antenna radiation is concentrated within the lobe width, the magnitude of which reflects the extent of radiation concentration of the antenna.
Fig. 5 shows a top view of a base station and a target building in the broadband access method according to the embodiment of the present application. It should be noted that, the rectangle shown in fig. 5 is an approximation of the target building, and the shape of the target building where the target user's home is located may be the rectangle shown in fig. 5 or may be another shape, which is not limited herein.
As shown in fig. 5, the distance between the target building and the base station includes: vertical distance D of base station to target building 1 Straight line distance D between base station and two horizontal boundary points of target building 2 、D 3 . Horizontal lobe width PAnd D 1 、D 2 、D 3 The following formula is satisfied:
step three: and calculating the vertical lobe width of the base station antenna according to the height of the target building, the height of the base station and the distance between the target building and the base station.
The angle between the two points at which the power gain drops by 3dB relative to the maximum point of the main lobe in the vertical plane pattern of the antenna is defined as the vertical lobe width of the antenna, also known as the vertical beam width or vertical lobe angle.
Fig. 6 shows a side view of a base station and a target building in the broadband access method according to the embodiment of the present application. As shown in fig. 6, for a high-rise building, the building is generally higher than the base station site. When the building is too tall (greater than 30 m) or the building site is too close (less than 20 m), the antenna beam needs to be transmitted upwards if coverage is desired for the tall building. But to avoid 5G handoff, the vertically outermost beam is typically transmitted toward the penultimate floor of the building. Thus, the vertical lobe width Q and the height H of the target building a Height H of base station b Vertical distance D between target building and base station 1 The following formula is satisfied:
where h represents the floor height of the target building, and is typically set to 3m.
Step four: the mode (pattern) of the base station antenna is determined based on the horizontal lobe width and the vertical lobe width.
Wherein the pattern includes a horizontal lobe width, a vertical lobe width, an electronic azimuth angle, and an electronic downtilt angle of the base station antenna.
Parameters that can be adjusted by the Massive MIMO antenna include horizontal bandwidth, vertical bandwidth, etc., and a combination of these parameters is a pattern, and antenna elements in Massive MIMO are all configured by a group of patterns. In a 5G scenario, one pattern is equal to the combination of parameters of "horizontal bandwidth + vertical bandwidth + downtilt + horizontal angle", and after introducing a large-scale antenna, the pattern selection of a 5G base station may be as many as ten thousand. And reasonably planning antenna parameters according to the coverage scene, and selecting a pattern suitable for the specific coverage scene. For example, for a relatively large square coverage, a pattern with a horizontal beam width needs to be selected, and for a high-rise building coverage, a pattern with a vertical beam width needs to be selected. As shown in table 1, the conventional technology summarizes the common patterns of the 5G base station antenna based on the coverage scene for different application scenarios. And selecting and determining patterns suitable for the target building scene from the table 1 according to the horizontal lobe width and the vertical lobe width obtained by calculation in the second step and the third step.
TABLE 1 general pattern selection
It should be noted that, the electronic azimuth angle and the electronic downtilt angle defined in pattern are realized by changing the phase of the antenna array. The main function of the electronic azimuth angle is to conduct electronic fine adjustment on the basis of the mechanical azimuth angle, so that the outermost wave beam in the horizontal direction is emitted at the edge of the target building.
The downward inclination angle of the antenna is defined as the included angle between the antenna and the vertical plane, and can be defined as the included angle between the radiation direction of the antenna and the horizontal direction, and is a default downward positive value and an upward negative value. The mechanical downtilt angle is realized by adjusting the position of the back support of the antenna to change the tilt angle of the antenna, the electronic downtilt angle is realized by adjusting the coil inside the antenna to achieve the aim of adjusting the signal downtilt angle of the antenna, and the antenna array is adjusted to realize the mechanical downtilt angle. When the downtilt angle is large, the lobes are deformed by adopting all mechanical tilt angles, so that the mechanical downtilt angle and the electronic downtilt angle are combined for use.
Step five: and determining the mechanical downtilt angle of the base station antenna according to the height of the target building, the height of the base station, the distance between the target building and the base station, the vertical lobe width and the electronic downtilt angle.
Fig. 7 shows a side view of a base station and a target building in the broadband access method according to the embodiment of the present application. As shown in fig. 7, the total downtilt is the angle between the central beam of the antenna and the horizontal direction, and is a negative value if the target building is a high-rise building or the base station is too close to the target building. Thus, the mechanical downtilt angle C is compared with the height H of the target building a Height H of base station b Vertical distance D between target building and base station 1 The vertical lobe width Q and the electron downtilt angle c satisfy the following formula:
s202, sending an adjustment instruction to a user.
The adjustment instruction is used for instructing the user to adjust the antenna of the base station to meet the antenna parameters, so that one sector of the base station mainly covers the target building. It should be noted that the broadband access device has a user interaction function and an interface, and the user is a base station maintainer.
After receiving the adjustment instruction, the user adjusts the mechanical azimuth angle, pattern and mechanical downtilt angle of the base station antenna in sequence according to the sequence from the first step to the fifth step, so that the main coverage area of a certain antenna sector of the base station corresponds to the target building.
S203, determining a feasible installation area meeting the requirement of the preset broadband service according to the network signal condition of the target user family.
The preset broadband service requirement is that the maximum bandwidth of the uplink and the downlink of the communication should meet the uplink 50Mbps and the downlink 100Mbps.
In one example, the living room signal strength is-107.66 dBm, the balcony signal strength is-98.5 dBm, and the room window out-of-room signal strength is-90.2 dBm. The living room can not meet the CPE signal access requirement for providing the rate of more than hundred megameters, and the balcony and the room window can meet the CPE signal access requirement outdoors, so that the balcony and the room window are determined to be feasible installation areas outdoors.
S204, determining the installation position of the client terminal equipment from the feasible installation area according to the indication of the target user.
The client terminal equipment is used for interfacing with a data network through the base station, so as to provide broadband network access and data connection for equipment in the home of the target user.
In one example, the target user selects a balcony from the available installation area as an installation location, and thus adopts a scheme in which CPE is installed on the outer wall surface of the balcony.
