Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" in the embodiment of the present invention is only one kind of association relationship describing an associated object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in the embodiment of the present invention generally indicates that the preceding and following related objects are in an "or" relationship.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
In the description of the present invention, "a plurality" means two or more unless otherwise specified.
According to the method for planning the wireless network site based on multiple operators provided by the embodiment of the invention, before a certain area (called a site planning area in the embodiment of the invention) is planned, the following preparation in two aspects 1 and 2 is needed:
1. and collecting the resource information of the current station address.
1.1 resource information Collection for multiple operators
The method comprises the steps of collecting and sorting resource information of a plurality of operators in a site planning area, wherein the resource information mainly comprises site position information which is constructed and planned and constructed, configuration information of a communication system, basic worker parameter information of the communication system and the like.
The station location information is mainly station longitude and latitude information; the system configuration information mainly includes the type of the communication system, the type of the antenna in the communication system, the frequency band of the communication system, the power of the communication system, and the like. The basic parameters of the communication system mainly comprise coordinates, azimuth angles, downtilt angles, electrical dip angles, feeder line lengths and the like of all station sites in the communication system. Optionally, the coordinates of each station address may be specifically accurate to the position of the sector antenna.
1.2 other site resource Collection
Other third party companies have built and planned sites for construction.
And available site location information provided by local government, which can be used as an alternative site.
Second aspect, simulation resource preparation
The simulation resource preparation mainly comprises simulation software, a map of a site planning area, a proper electromagnetic propagation model and the like.
The network simulation software should include automatic cell optimization and automatic site planning functions. For example, Forsk Atoll simulation software may be used in the embodiment of the present invention.
The accuracy of the map may be set according to the importance of the site planning area, the density of buildings, etc. For example, the accuracy of an urban area with dense buildings in the map can be set to be not less than 5m, and the accuracy of other areas is not less than 20 m.
The electromagnetic propagation model needs to be corrected, and can be generally corrected through a CW test. Optionally, a ray tracing type electromagnetic propagation model is preferably selected in the urban area, and a statistical type electromagnetic propagation model is selected in other areas. The propagation model is usually corrected by using C/W test data, the mean square error after correction should be controlled below 8dB, and the mean square error should be controlled below 5dB for a ray tracing type electromagnetic propagation model.
Where CW is an abbreviation of Continuous Wave, i.e., Continuous Wave. The CW test is to use continuous waves as a signal source to test the propagation loss. When continuous waves are used as a signal source, the propagation loss of the signal is only related to the wireless environment and is not related to the signal, and the data obtained by testing by adopting the method is used for correcting an electromagnetic propagation model to obtain the electromagnetic propagation model which accords with the actual electromagnetic propagation condition of the area.
As shown in fig. 1, an embodiment of the present invention provides a method for planning a wireless network site based on multiple operators, including:
s101, determining a first station address set.
The first station address set is a set of station addresses which are built and planned and built in the station address planning area.
And combining and counting site resources of a plurality of operators and site resources of a third party in the site planning region to determine a set of sites which are constructed and planned and constructed in the site planning region.
When making statistics, it is noted that the base station shared by multiple operators is calculated only once.
Alternatively, when determining a site shared by multiple operators, the determination may be performed according to the site name or the distance, for example, a base station with the same site name may be regarded as a shared base station, or a base station with highly similar location coordinates within 30m may be regarded as a shared base station, and for example, an Excel tool may be used to perform recognition calculation statistics. If it is practically impossible to discern whether the co-sited suspect sites can all remain, the simulation tool can handle this situation.
In the embodiments of the present invention, the following examples all describe an example in which 3 operators (operator 1, operator 2, and operator 3) are included in a site planning region.
For example, there are three operators in the site planning region, and statistics of the number of sites constructed and planned and constructed by the three operators in the site planning region are shown in table 1 below:
TABLE 1
In addition, 4 third-party constructed and planned sites exist in the site planning area, the 4 sites are merged with the sites in the table 1, and the total 90 sites are counted in the site resource set after the treatment.
S102, determining a first communication system.
The first communication system plans a communication system with the highest frequency band for a plurality of operators in a station address planning area.
In the site planning region, the frequency bands adopted by the communication systems planned to be constructed (i.e. constructed or prepared) by each operator are different. The communication system with the highest frequency band can be selected as the first communication system from the communication systems which are heavily constructed by a plurality of operators.
Each communication system has a coverage standard of wireless signals, and the coverage standard mainly relates to standards of parameters such as RSRP (Reference Signal Receiving Power, chinese) edge coverage level value, coverage Ratio, and SINR (Signal to Interference plus Noise Ratio, chinese).
For example, coverage criteria for a communication system constructed by 3 operators in a site planning region are shown in table 2.
TABLE 2
In the embodiment of the present invention, the execution sequence of S101 and S102 is not limited, that is, S101 may be executed first, and then S102 may be executed; s101 may be executed after S102 is executed; s101 and S102 described above may also be performed simultaneously.
S103, on the basis of the first station address set, automatic station address planning based on an electromagnetic propagation prediction method is carried out on the first communication system, so that a second station address set meeting a first condition is obtained.
Wherein the first condition comprises: the reference signal received power RSRP edge coverage level value of the site planning area and the level threshold value of the first communication system, and the coverage proportion of the site planning area and the coverage proportion threshold value of the first communication system.
The level threshold of the first communication system is an RSRP edge coverage level value that meets a coverage standard of the first communication system, the coverage ratio threshold of the first communication system is a coverage ratio that meets the coverage standard of the first communication system, and if the communication system of the communication system to be constructed by the operator 1 shown in table 2 is the first communication system, the level threshold of the first communication system is-98; the coverage percentage threshold of the first communication system is 95%. The first condition may be determined according to coverage criteria of the communication system proposed by the operator 1 in table 2.
Optionally, in order to ensure the coverage effect of the first communication system, the coverage standard of the first communication system may be increased based on the existing coverage standard of the first communication system, for example, when the first communication system plans the coverage standard of the communication system established by operator 1 in table 2 above, the standard of RSRP edge coverage level value (dBm) may be increased by 3dB, and the standard of coverage ratio may be increased by 3 percent.
Optionally, on the basis of performing automatic site planning according to the first condition, the automatic site planning in the implementation of the present invention may further include performing automatic site planning according to at least one of the following conditions: condition 1, site setting is performed for different ground feature types. And 2, setting different site types for different areas. Condition 3, at least one of the RSRP edge coverage level values is set for different regions. That is, in the embodiment of the present invention, based on the first condition, at least one of the conditions 1, 2, and 3 may be selected again for automatic site planning.
For example, when the station addresses are set for different types of land features, the station addresses in some types of land features can be preferentially set, the station addresses in some types of land features are forbidden to be set, the station addresses in some types of land features are heightened, and the like, so that later manual adjustment is avoided. For example, it is preferable to set a site on an open lawn rather than a site in the water.
For example, when different site types are set for different areas, two site types, namely a macro base station and a micro base station, may be selected to cooperate in a hot spot area (for example, an area with a high population density and a high requirement on a transmission rate of a communication system) to ensure the transmission rate in the area, and only the macro base station may be selected in a non-hot spot area.
For example, when RSRP edge coverage level values are set for different regions, RSRP edge coverage level value criteria may be set specifically according to the types of surface features of the different regions.
Optionally, taking the first station address set including 90 station addresses as an example, if the second station address set determined after the automatic station address planning is performed by using the method in S103 includes 118 station addresses, it indicates that 28 station addresses need to be added.
And S104, aiming at a communication system planned by a single operator in the site planning area, performing automatic cell optimization based on an electromagnetic propagation prediction method to screen out a site set of the single operator meeting a second condition from a second site set.
In the embodiment of the invention, the electromagnetic propagation prediction method is an electromagnetic propagation prediction method adopted on the basis of an electromagnetic propagation model of a station planning region.
Wherein the second condition comprises: the RSRP edge coverage level value of the site planning region and the level threshold value of the single operator proposed communication system are in a size relationship, the coverage proportion of the site planning region and the coverage proportion threshold value of the single operator proposed communication system are in a size relationship, and the SINR proportion of the site planning region larger than the SINR threshold value of the single operator proposed communication system and the SINR proportion threshold value of the single operator proposed communication system are in a size relationship.
For example, the second condition may be determined according to the coverage standard of the communication system proposed by each operator in table 2.
Optionally, the second site set may use the constructed and planned sites belonging to a single operator as a base site set, and the remaining sites as alternative site sets.
The step of planning a communication system for a single operator in a site planning region to perform automatic cell optimization based on an electromagnetic propagation prediction method may include the following a or B.
A. And deleting and/or adjusting the site parameters are allowed for the sites in the base site set, and the site parameters are allowed for the sites in the alternative site set.
B. And allowing the parameters of the station address to be adjusted when the station address in the base station address set is not allowed to be deleted, and allowing the parameters of the station address to be deleted and/or adjusted when the station address in the alternative station address set is deleted.
Wherein, adjusting the site parameter may include: and adjusting station parameters, power, antennas and the like of the station site.
Optionally, the second condition further includes: the method comprises the steps that at least one of the relationship between the planning cost of the site planning region and the cost threshold of the proposed communication system of a single operator, the relationship between the overlapping coverage rate of the site planning region and the overlapping coverage rate threshold of the proposed communication system of the single operator, and the relationship between the service rate of the site planning region and the service rate threshold of the proposed communication system of the single operator is obtained.
After S104, the method provided in the embodiment of the present invention may further include the following steps S105 and S106.
And S105, determining shared sites of a plurality of operators according to the site set of each operator.
Optionally, each operator may select a station address satisfying the second condition from the second station address set, where the repeatedly selected station address is the shared station address (or the co-established station address). The process can be completely determined according to electromagnetic propagation prediction, and the problems of poor later-stage coverage effect and investment waste possibly caused by the traditional distance method are solved.
Optionally, the site set of the single operator meeting the second condition includes the site already constructed and planned to be constructed and the newly added site of the single operator.
And S106, sequencing and integrating the sites built and planned and built by each operator and the newly added sites according to the number of the operators sharing the site so as to obtain the priority of the site of each operator.
And if the number of the operators sharing the built and planned site is the same as that of the operators sharing the newly added site, the priority of the built and planned site is higher than that of the newly added site.
For example, the priority ranking of the sites of each operator can be shown in table 3, wherein the built and planned sites are represented by the used sites in table 3.
TABLE 3
After S106, each operator may determine the order of building the sites according to the priority of the sites of each operator.
For example, the station addresses may be constructed according to the priority ranking of the station addresses of the operators shown in table 3, where when an old station address shared by multiple operators is constructed, a new station is not needed, and only an original station needs to be configured as a station that can be shared by multiple operators, for example, the old station address 1 is configured as a station that can be shared by the operators 1, 2, and 3, and for the new station addresses in table 3, new stations need to be added, and corresponding configuration is performed, for example, the new station address 1 is added, and is configured as a station that can be shared by the operators 1, 2, and 3.
