Description

Network coverage determination method, device and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a network coverage determining method, a device, and a storage medium.

Background

With the development of mobile communication technology, the service requirements of network communication are becoming finer. Different network traffic often has different quality of service (quality of service, qoS) requirements.

However, the network coverage area of the access network device is generally calculated according to the signal strength transmitted by the access network device. The signal strength is related to the transmitting power, the signal transmitting frequency and the detecting position of the access network equipment. And the signal transmission frequency is determined by a different network communication protocol. Therefore, the current description of the network coverage area of the access network device can only be directed to different communication networks, such as a 4G communication network, a 5G communication network, etc., and the description granularity is too coarse to accurately reflect the actual network coverage area of the access network device, so that it is difficult to satisfy the service development requirement of network communication.

Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the description of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more.

The following explains the terms related to the embodiments of the present application, so as to facilitate the understanding of the reader.

(1) Quality of service (quality of service, qoS)

QoS is used for monitoring service quality of network communication so as to provide corresponding service quality for different services, thereby avoiding network congestion and improving network communication efficiency. QoS parameters include latency, bandwidth, jitter, reliability, etc.

(2) Network slice (network slice, NS)

The principle of network slicing is that a physical network is divided into a plurality of virtual networks through slicing, and each virtual network is divided according to different service requirements such as time delay, bandwidth, jitter, safety, reliability and the like, so that the differentiated requirements of different services are respectively met.

The network slices are logically independent, and the failure of any one network slice does not affect other network slices. Each network slice has different functional characteristics and faces different requirements and services.

There are various types of network slices, and in a 5G network, the types of network slices generally include: enhanced mobile broadband (Enhanced Mobile Broadband, emBB) traffic slices, high reliability low latency communication (Ultra-reliable and Low Latency Communications, ul rllc) traffic slices, and mass machine type communication (Massive Machine Type Communications, mctc) traffic slices.

The eMMB service is a high-flow mobile broadband service for further improving the performances of user experience and the like on the basis of the existing mobile broadband service scene. Accordingly, for eMMB traffic slices, the traffic rate has a greater impact on the quality of service (Quality of Service, qoS) of the traffic.

The ulllc service is a service requiring low delay, and is generally applied to the unmanned technical field and the industrial automation technical field, for example. Correspondingly, for the uRLLc service slices, the service delay has a larger influence on the service QoS.

The mMTC service refers to a large-scale Internet of things service, and is connected with a large number of machines for communication. Correspondingly, for the mctc service slice, the service packet loss rate has a larger influence on the service QoS.

Aiming at more refined service requirements, the network slice can be further classified through specific QoS parameters. Different network slices correspond to different QoS parameters.

The following describes embodiments of the present application in detail with reference to the drawings.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a communication system 10 according to an embodiment of the present application. The communication system 10 includes: at least one access network device 112 and at least one terminal 111. Terminal 111 is in network communication with access network device 112 via a communication link. The terminals 111 communicate with each other via a communication link. Network communications are conducted between access network devices 112 via a communication link.

The communication system 10 shown in fig. 1 may be applied to 5G networks, but also to 4G or other networks in the future. Of course, the communication system 10 shown in fig. 1 may also be applied to a system of 4G and 5G hybrid networking, or other systems, which is not specifically limited in this embodiment of the present application. In this case, the terminal device and the access network device in the communication system 10 may correspond to different names in different networks, and those skilled in the art will understand that the names do not limit the devices themselves.

Terminal 111, which is a device with wireless communication capabilities, may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted. Can also be deployed on the water surface (such as a ship, etc.). But may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). Terminals, also called User Equipment (UE), mobile Stations (MSs), mobile Terminals (MT), and terminal equipment, etc., are devices that provide voice and/or data connectivity to a user. For example, the terminal includes a handheld device, an in-vehicle device, and the like having a wireless connection function.

In this application, for convenience of description, a Chip disposed in the above device, such as a System-On-a-Chip (SOC), a baseband Chip, etc., or other chips having a communication function may also be referred to as a terminal.

The terminal can be a vehicle with corresponding communication function, or a vehicle-mounted communication device, or other embedded communication devices, or can be a handheld communication device of a user, including a mobile phone, a tablet personal computer and the like.

As an example, in the embodiment of the present application, the terminal 111 may also be a wearable device.

The system architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and as a person skilled in the art can know that, with evolution of the network architecture and occurrence of a new service scenario, the technical solution provided in the embodiments of the present application is applicable to similar technical problems, and the following embodiments take a 5G communication system as an example.

It should be noted that the embodiments of the present application may refer to or refer to each other, for example, the same or similar steps, and the method embodiment, the communication system 10 embodiment, and the device embodiment may refer to each other, which is not limited.

Based on the communication system shown in fig. 1, the prior art generally determines the network coverage area of an access network device by measuring the signal strength of the access network device. The signal strength of the access network device is related to factors such as the transmitting power of the access network device, the transmitting frequency of the signal, the distance between the current position and the access network device, path interference and the like. The network communication protocol specifies the frequencies of the upstream and downstream transmissions of the communication network. Thus, prior art solutions can only determine the network coverage area of an access network device for different communication networks.

However, taking the 5G communication system as an example, the services of the user equipment are carried on the network slice, and different services have different service requirements. Even if the user equipment is able to communicate with the access network equipment, its current quality of service may not meet the service requirements of the user equipment. Obviously, the prior art does not accurately reflect the actual network coverage capabilities of the access network device.

In order to solve the problem that the actual network coverage capability of access network equipment cannot be accurately reflected in the prior art, the application provides a network coverage determination method.

Referring to fig. 1, as shown in fig. 2, fig. 2 is a flowchart of a network coverage determining method provided in an embodiment of the present application, where the method includes the following steps:

s201, the network coverage determining device acquires a first network slice of the access network equipment.

Wherein the access network device comprises at least one network slice, the first network slice being any one of the at least one network slice of the access network device.

It should be noted that, in the embodiment of the present application, different network slices are used to carry different services. The QoS parameters of a network slice may characterize the traffic demands of the corresponding traffic. Thus, in the embodiments of the present application, qoS parameters may be used as a basis for classifying network slices.

In one possible implementation manner, the network coverage determining device divides network resources according to QoS requirements of the network slices, so as to obtain different network slices.

In one possible implementation manner, the network coverage determining device may number at least one network slice, and set a mapping relationship between the number and the QoS parameter, so that different network slices are represented by the number of the network slice.

Illustratively, the access network device includes 5 network slices, numbered correspondingly as network slice #1, network slice #2, network slice #3, network slice #4, and network slice #5. Network slice #1 corresponds to QoS parameter 1, network slice #2 corresponds to QoS parameter 2, network slice #3 corresponds to QoS parameter 3, network slice #4 corresponds to QoS parameter 4, and network slice #5 corresponds to QoS parameter 5. The network coverage determination means sets a mapping relationship between the number of the network slice and the QoS parameter of the corresponding network slice, and the network slice is represented by the number of the network slice. At this time, the network coverage determining means may determine the network slice and the QoS parameter corresponding to the network slice according to the number of the network slice.

S202, the network coverage determining device determines a slice coverage area of the first network slice.

The slice coverage area comprises an area where the QoS parameters of the first network slice meet preset conditions, and the slice coverage area is represented by at least one three-dimensional shape.

In one possible implementation, the slice coverage area may include all areas where the QoS parameters of the first network slice satisfy the preset condition.

In one possible implementation, the preset condition may be that the measured QoS parameter is better than the QoS parameter requirement of the first network slice.

Exemplary, the QoS parameter requirements of the first network slice are: delay 3ms and bandwidth 10Mb/s. The QoS parameters measured at a point near the access network device are latency 2ms and bandwidth 12Mb/s. For the time delay, the lower the time delay, the higher the QoS parameter is; for bandwidth, the larger the bandwidth, the higher the QoS parameter is explained. Thus, the QoS parameters measured at a point in the vicinity of the access network device are better than the QoS parameter requirements of the first network slice, i.e. the QoS parameters of the first network slice at the current location meet the preset conditions.

It should be noted that the slice coverage area may be represented by at least one three-dimensional shape. Compared with the technical scheme that the network coverage area of the access network equipment is described through the coverage radius, the slice coverage area of the first network slice is represented through at least one three-dimensional shape, so that the network coverage condition of the first network slice on the three-dimensional space can be described, and meanwhile, the shape of the network coverage of the first network slice can be clearly and accurately defined.

In one possible implementation, the slice coverage area may be expressed by the following formula:

NS _i ＝{A ₁ ,A ₂ ,……A _n }；

wherein NS is _i Representing an ith first network slice of the at least one network slice, A ₁ ,A ₂ ……A _n Is at least one solid shape, and i and n are positive integers.

S203, the network coverage determining device determines that the coverage area of the access network device includes a slice coverage area of each first network slice.

In particular, the access network device comprises at least one network slice, the first network slice being any one of the at least one network slice. Each first network slice has its corresponding slice coverage area. Thus, the network coverage determination means may take the slice coverage area of each first network slice as the coverage area of the access network device.

In one possible implementation manner, when the access network device is a miniaturized base station, since the miniaturized base stations are generally disposed in relatively close positions, the network coverage determining device may use the miniaturized base stations as a whole to determine coverage areas of the miniaturized base stations.

The process of the network coverage determining means determining the slice coverage areas of the first network slices and determining the coverage area of the access network device from the slice coverage area of each first network slice is described in detail above in connection with steps S201-S203.

Hereinafter, a process of determining the slice coverage area of the first network slice by the network coverage determining means will be specifically described in connection with the above step S202.

Referring to fig. 2, as shown in fig. 3, the above step S202 may be specifically implemented by the following steps S2021 to S2023:

s2021, the network coverage determining means determines a plurality of coverage boundary points of the first network slice.

On the coverage boundary point, the QoS parameter of the access network device meets the preset condition corresponding to the first network slice.

Specifically, the coverage boundary point refers to a boundary point at which the service QoS parameter measured at the point just meets the QoS parameter requirement corresponding to the first network slice.

In one possible implementation, the preset condition may be that, at a coverage boundary point, the measured QoS parameter of the access network device is better than the QoS parameter requirement of the first network slice, and a difference between at least one of the measured QoS parameters and a corresponding parameter of the QoS parameters of the first network slice is less than or equal to a preset threshold.

Illustratively, the preset threshold for delay in the preset condition is 0.1ms and the preset threshold for bandwidth is 0.1Mb/s. The QoS parameters of the first network slice include: delay 3ms and bandwidth 10Mb/s. On the coverage boundary point, the measured QoS parameters of the access network equipment are time delay 2.9ms and bandwidth 11Mb/s. At this time, the measured QoS parameters are better than the QoS parameter requirements of the first network slice, and meanwhile, the difference between the time delay of the measured QoS parameters and the time delay of the QoS parameters of the first network slice is 0.1ms, which is equal to the preset threshold. Therefore, the measurement position at this time is a coverage boundary point of the first network slice.

S2022, the network coverage determining device determines at least one three-dimensional shape according to the plurality of coverage boundary points.

Specifically, in the embodiment of the present application, the network coverage determining device may sequentially connect the coverage boundary points according to more than four coverage boundary points, to obtain at least one three-dimensional shape.

In one possible implementation manner, the network coverage determining device may determine a complete three-dimensional shape according to the plurality of coverage boundary points, and then decompose the complete three-dimensional shape into at least one three-dimensional shape through a preset algorithm, so that the communication network determines the service requirement corresponding to the first network slice according to the at least one three-dimensional shape.

The preset algorithm may be, for example, a convex decomposition (convex decomposition) algorithm. The network coverage determination means may decompose the complete three-dimensional shape into at least one convex polyhedron by a convex decomposition algorithm. The network coverage determination means may also decompose the complete three-dimensional shape into at least one three-dimensional shape in other ways, which are not limited in this application.

S2023, the network coverage determining means determines that the at least one stereoscopic shape is a slice coverage area of the first network slice.

NS _i ＝{A ₁ ,A ₂ ,……A _n }；

It should be noted that, in the above embodiment, the QoS parameter of the access device is measured by a point located near the access network device. This approach may be applied to access network devices that have been formally operated.

The QoS parameters of the access device may be obtained by measurement performed by an unmanned vehicle or an unmanned plane, or may be obtained by measurement performed by other measurement devices. The present application is not limited in this regard.

In one possible implementation manner, the network coverage determining device estimates QoS parameters of the access network device by acquiring geographic information data and signal simulation data of the access network device. The method can be applied to access network equipment which is not built.

Based on the technical scheme, the network coverage determining device represents the slice coverage area of the first network slice through at least one three-dimensional shape, and can reflect the slice coverage area of the first network slice more specifically and accurately, so that the communication network can determine the service requirement corresponding to the first network slice according to the at least one three-dimensional shape.

Referring to fig. 3, as shown in fig. 4, after the network coverage determining device determines at least one stereoscopic shape according to the plurality of coverage boundary points in the above step S2022, the method further includes the steps of:

s2024, the network coverage determining device determines a preset space coordinate system.

In a possible implementation manner, the origin of coordinates of the preset spatial coordinate system may be the location of the access network device.

In one possible implementation, the preset space coordinate system may be a space rectangular coordinate system.

For example, as shown in fig. 5, when the preset space coordinate system is a space rectangular coordinate system, the origin of coordinates of the space rectangular coordinate system is the position of the access network device, and the network coverage determining device may use a direction perpendicular to the horizontal plane upwards as the z-axis direction of the space rectangular coordinate system, use a direction parallel to the horizontal plane to the east as the x-axis direction of the space rectangular coordinate system, and use a direction parallel to the horizontal plane to the north as the y-axis direction of the space rectangular coordinate system.

For regular solid shapes, the network coverage determination means may represent the solid shape by a simplest mathematical quantity. The simplest mathematical quantity refers to that the shape and the position of the three-dimensional shape in a preset space coordinate system can be determined by the minimum coordinate parameters related to the three-dimensional shape.

wherein A is _j Represents the j-th stereoscopic shape of the at least one stereoscopic shape, ID ₃ Is of the type with a three-dimensional shape of an ellipsoid, (x) ₀ ,y ₀ ,z ₀ ) G, h and k are the half-axis lengths of the ellipsoid, and j is a positive integer.

It should be noted that, the network coverage determining device may also represent, by the simplest mathematical expression, other regular solid shapes such as spheres, cylinders, cones, rings, and the like, which will not be specifically described in the embodiments of the present application.

S2027, the network coverage determining means determines that the parameters of the at least one stereoscopic shape include a type of the at least one stereoscopic shape, and coordinate parameters of the at least one stereoscopic shape within a preset spatial coordinate system.

According to the technical scheme, the network coverage determining device determines the preset space coordinate system, maps the determined at least one three-dimensional shape into the preset space coordinate system, and represents the specific position and the specific shape of the three-dimensional shape through the type of the three-dimensional shape and the three-dimensional shape coordinate parameters, so that the communication network can better determine the slice coverage area corresponding to the first network slice.

In the above, the process of determining the slice coverage area of the first network slice by the network coverage determining device and determining the coverage area of the access network device according to the slice coverage area of each first network slice in the embodiment of the present application is described in detail.

Hereinafter, in connection with the above embodiment, a process of determining the slice coverage condition in the first area and determining whether the service in the first area meets the requirement by the network coverage determining device will be specifically described.

It should be noted that the following embodiments may be performed in conjunction with the embodiment of fig. 2, may be performed in conjunction with the embodiment of fig. 3, and may be performed in conjunction with the embodiment of fig. 4. The following will take an example in conjunction with fig. 2.

Referring to fig. 2, as shown in fig. 6, a network coverage determining method provided in an embodiment of the present application further includes the following steps:

s301, a network coverage determining device determines a first area.

Wherein the first area includes at least one access network device.

As an example, the first area may be a service coverage area of a service to be subscribed to.

S302, the network coverage determining device determines the coverage area of each access network device in at least one access network device.

S303, the network coverage determining device determines the slice coverage condition in the first area according to the coverage area of at least one access network device.

Wherein the slice coverage situation within the first area is used to characterize a slice coverage area of each network slice of each of the at least one access network device.

Specifically, as can be seen from the above embodiments, the coverage area of the access network device includes the slice coverage area of each first network slice. Meanwhile, the first area comprises at least one access network device. Thus, the network coverage determination means may determine a coverage area of at least one access network device comprised within the first area.

In one possible implementation manner, the network coverage determining means may determine a slice coverage area of any one network slice in each access network device in the first area, and the network coverage determining means regards a set of slice coverage areas of any one network slice in each access network device in the first area as a slice coverage situation in the first area. At this time, the slice coverage of the first area includes a slice coverage of each network slice in the first area.

Based on the technical scheme, the network coverage determining device determines the slice coverage condition in the first area through the network coverage area of the access network equipment included in the first area, and can more specifically and accurately reflect the slice coverage condition in the first area so as to determine the service requirement in the first area.

Hereinafter, a process of determining whether the service in the first area satisfies the requirement by the network coverage determining means will be specifically described in connection with the above embodiments.

Referring to fig. 6, as shown in fig. 7, a network coverage determining method provided in an embodiment of the present application further includes the following steps:

s304, the network coverage determining device determines a service coverage area of the service to be signed.

The service coverage area of the service to be signed is located in the first area. The service coverage area of the service to be signed refers to the working area of the user equipment corresponding to the service to be signed.

In one possible implementation, the ue is a ue that is movable within a coverage area of a service to be subscribed to.

In yet another possible implementation manner, the ue is an immovable ue disposed in a coverage area of a service to be subscribed to.

In a possible implementation manner, the service coverage area of the service to be subscribed may be determined by means of the slice coverage area of the first network slice of the network coverage determining device in step S202, or steps S2021-S2022, or steps S2024-S2027, and the details refer to the above embodiment.

By way of example, the service coverage area of a service to be subscribed to may be expressed by the following formula:

US＝{B ₁ ,B ₂ ,B ₃ ,B ₄ ,B ₅ }；

wherein, US represents the service coverage area of the service to be signed, B ₁ ,B ₂ ,B ₃ ,B ₄ ,B ₅ Is a three-dimensional shape of 5 service coverage areas for representing the service to be subscribed to. The 5 solid shapes may be regular solid shapes or irregular solid shapes. The 5 three-dimensional shapes can be represented by the manner in steps S2024 to S2027.

S305, the network coverage determining means determines a slice coverage area of the second network slice.

The second network slice is a network slice corresponding to the service to be signed in the first area.

Specifically, the second network slice may be the same type of network slice corresponding to the service to be signed in the multiple access network devices in the first area.

In one possible implementation manner, the network coverage determining device determines a QoS parameter requirement of a service to be subscribed, and takes a network slice capable of meeting the QoS parameter requirement in the first area as the second network slice.

In another possible implementation manner, the network coverage determining device may further number the network slice in the first area and the network slice corresponding to the service to be signed, and set a mapping relationship between the number of the network slice in the first area and the QoS parameter, and a mapping relationship between the number of the network slice corresponding to the service to be signed and the QoS parameter, respectively. The network coverage determining device takes the network slice in the first area, which is the same as the QoS parameter mapped by the number of the network slice corresponding to the service to be signed, as the second network slice.

In combination with the above example, the network coverage determining device determines that the QoS parameter of the network slice corresponding to the service to be signed is time delay 2ms and bandwidth 16Mb/s. The network coverage determining device takes a network slice with the QoS parameter of the network slice in the first area being 2ms time delay and the bandwidth being 16Mb/s as a second network slice, and the QoS parameter is expressed by the following formula:

NS ₂ ＝{A ₁ ,A ₂ ,A ₃ ,A ₄ }；

Wherein NS is ₂ Representing a second network slice, A ₁ ,A ₂ ,A ₃ ,A ₄ Is 4 three dimensional shapes for representing the slice coverage area of the second network slice. The 5 solid shapes may be regular solid shapes or irregular solid shapes. The 5 three-dimensional shapes can be represented by the manner in steps S2024 to S2027.

S306, in the case that the slice coverage area of the second network slice comprises all service coverage areas of the service to be signed, the network coverage determining device determines that the slice coverage condition in the first area meets the coverage requirement of the service to be signed.

In one possible implementation manner, after the network coverage determining device determines that the slice coverage condition in the first area meets the coverage requirement of the service to be subscribed, the service to be subscribed may be subscribed.

S307, in the case that the slice coverage area of the second network slice does not include all service coverage areas of the service to be signed, the network coverage determining device determines that the slice coverage condition in the first area does not meet the coverage requirement of the service to be signed.

In a possible implementation manner, after the network coverage determining device determines that the slice coverage condition in the first area does not meet the coverage requirement of the service to be subscribed, an uncovered slice coverage area may be determined according to the slice coverage condition in the first area and the service coverage area of the service to be subscribed, and the access network device construction target may be determined according to the uncovered slice coverage area.

In combination with the above-described examples,the network coverage determination means determine a service coverage area US of the service to be subscribed to and a slice coverage area NS of the second network slice ₂ 。

The network coverage determination means compares the service coverage areas US of the service to be subscribed to and the slice coverage areas NS of the second network slice ₂ ：

When US e NS ₂ When the slice coverage area of the second network slice comprises all service coverage areas of the service to be signed, the network coverage determining device determines that the slice coverage condition in the first area meets the coverage requirement of the service to be signed, and signs the service to be signed.

When (when)When the slice coverage area of the second network slice does not include all service coverage areas of the service to be signed, the network coverage determining device determines that the slice coverage condition in the first area does not meet the coverage requirement of the service to be signed, and calculates: />

CS＝US-NS ₂ ；

Wherein CS represents a coverage area of the service to be subscribed that is not comprised by the slice coverage area of the second network slice.

The network coverage determining device determines an access network device construction target according to the CS.

By the technical scheme, the network coverage determining device determines the service coverage area of the service to be signed and the slice coverage area of the second network slice, and determines whether the slice coverage condition in the first area meets the coverage requirement of the service to be signed according to the service coverage area and the slice coverage area, so that the network coverage capability and the service requirement condition under different QoS requirements in the first area can be accurately reflected.
