Background

With the development of mobile communication technology, the service requirements of network communication are increasingly refined. Different network communication services often have different quality of service (QoS) requirements.

However, at present, the network coverage area of the access network device is usually calculated according to the strength of the signal transmitted by the access network device. Wherein, the signal strength is related to the transmitting power, the signal transmitting frequency and the detection position of the access network equipment. And the signal transmission frequency is determined by a different network communication protocol. Therefore, at present, description of the network coverage area of the access network device can only be performed for different communication networks, such as a 4G communication network, a 5G communication network, and the like, and the description granularity is too coarse, so that the actual network coverage area of the access network device cannot be accurately reflected, and the requirement of service development of network communication is difficult to meet.

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

Hereinafter, terms related to the embodiments of the present application are explained for the convenience of the reader.

(1) Quality of service (QoS)

The QoS is used to monitor the service quality of the network communication service to provide corresponding service quality for different services, thereby avoiding network congestion and improving the efficiency of network communication. 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 differentiation requirements of different services are met respectively.

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 is oriented to 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 (emBB) traffic slices, high-reliable and Low Latency Communications (urlcl) traffic slices, and mass Machine Type Communications (mtc) traffic slices.

The eMB service is a large-flow mobile broadband service for further improving the performance of user experience and the like on the basis of the existing mobile broadband service scene. Accordingly, for the eMMB Service slice, the influence of the Service rate on the Quality of Service (QoS) is large.

The urrllc service is a service requiring low delay, and for example, the urrllc service is generally applied to the fields of unmanned technology and industrial automation technology. Correspondingly, for the urrllc service slice, the influence of the service delay on the service QoS is large.

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 mtc service slice, the service packet loss rate has a large influence on the QoS of the service.

For more detailed service requirements, the network slices can be further classified according to specific QoS parameters. Different network slices correspond to different QoS parameters.

The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings.

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

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

The system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and it is known by those skilled in the art that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems, and the following embodiment takes 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, method embodiments, communication system 10 embodiments, and apparatus embodiments, may refer to each other, and are not limited.

Based on the communication system shown in fig. 1, it is common in the prior art to measure the signal strength of the access network device to determine the network coverage area of the access network device. The signal strength of the access network device is related to the transmission power, the signal transmission frequency, the distance between the current position and the access network device, the path interference and other factors of the access network device. Network communication protocols specify the frequencies of uplink and downlink transmissions of the communication network. Therefore, the solutions in the prior art can only determine the network coverage area of the access network device for different communication networks.

However, taking the 5G communication system as an example, the service of the ue is 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 cannot accurately reflect the actual network coverage capability 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 and 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 obtains a first network slice of the access network equipment.

The access network device comprises at least one network slice, and the first network slice is 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 for carrying different services. The QoS parameters of a network slice may characterize the traffic demand of the corresponding traffic. Therefore, in the embodiment of the present application, the QoS parameter can be used as a basis for classifying the network slices.

In a possible implementation manner, the network coverage determining apparatus divides network resources according to QoS requirements of network slices to obtain different network slices.

In a possible implementation manner, the network coverage determining apparatus 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, correspondingly numbered 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 device sets a mapping relation 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 parameter of the first network slice meets a preset condition, 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 parameter of the first network slice satisfies a 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.

Illustratively, the QoS parameter requirements of the first network slice are: a delay of 3ms and a bandwidth of 10 Mb/s. The QoS parameters measured at a point near the access network equipment are delay 2ms and bandwidth 12 Mb/s. For the time delay, the lower the time delay is, the higher the QoS parameter is; for bandwidth, the larger the bandwidth, the higher the QoS parameter. Therefore, the QoS parameter measured at a certain point near the access network device is better than the QoS parameter requirement of the first network slice, i.e. the QoS parameter of the first network slice at the current location meets the preset condition.

It should be noted that the slice coverage area may be represented by at least one solid 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 represented by the at least one stereoscopic shape can describe not only the network coverage condition of the first network slice on the stereoscopic space, but also clearly and accurately define the shape of the network coverage of the first network slice.

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

NS_i＝{A₁,A₂,……A_n}；

wherein NS_iRepresents the ith first network slice, A, of the at least one network slice₁,A₂……A_nIs 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.

Specifically, the access network device includes at least one network slice, and the first network slice is any one of the at least one network slice. For each first network slice, there is 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 a possible implementation manner, when the access network device is a small-sized base station, since the small-sized base stations are usually located in close proximity, the network coverage determining apparatus may use a plurality of small-sized base stations as a whole to determine the coverage areas of the plurality of small-sized base stations.

In the above, with reference to steps S201 to S203, a detailed description is given of a process in which the network coverage determination apparatus determines slice coverage areas of the first network slices and determines a coverage area of the access network device according to the slice coverage area of each first network slice.

Hereinafter, a process of the network coverage determining apparatus determining the slice coverage area of the first network slice will be specifically described with reference to the above step S202.

With reference to fig. 2, as shown in fig. 3, the step S202 can be specifically realized by the following steps S2021 to S2023:

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

And the QoS parameters of the access network equipment meet the preset conditions corresponding to the first network slice on the coverage boundary point.

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

In a possible implementation manner, the preset condition may be that, at the 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 in the QoS parameter of the first network slice is less than or equal to a preset threshold.

Illustratively, the preset threshold of the time delay is 0.1ms and the preset threshold of the bandwidth is 0.1Mb/s in the preset condition. The QoS parameters of the first network slice include: a delay of 3ms and a bandwidth of 10 Mb/s. And at the coverage boundary point, the measured QoS parameters of the access network equipment are 2.9ms of time delay and 11Mb/s of bandwidth. At the moment, the measured QoS parameters are all superior to the QoS parameter requirement of the first network slice, and meanwhile, the difference value 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 and is equal to the preset threshold value. Therefore, the measurement position at this time is an overlay boundary point of the first network slice.

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

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

In a 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 a service requirement corresponding to the first network slice according to the at least one three-dimensional shape.

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

S2023, the network coverage determining device determines at least one stereoscopic shape to be a slice coverage area of the first network slice.

NS_i＝{A₁,A₂,……A_n}；

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

Illustratively, the QoS parameter of the access device may be obtained by performing measurement by an unmanned vehicle or an unmanned aerial vehicle, or may be obtained by measuring by other measurement devices. This is not limited in this application.

In one possible implementation, the network coverage determining apparatus estimates the QoS parameter of the access network device by obtaining the geographic information data and the 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 more specifically and accurately reflect the slice coverage area of the first network slice, 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 apparatus determines at least one three-dimensional shape according to a plurality of coverage boundary points in step S2022, the method further includes the following steps:

and S2024, determining a preset space coordinate system by the network coverage determination device.

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 predetermined spatial coordinate system may be a spatial rectangular coordinate system.

For example, as shown in fig. 5, when the predetermined spatial coordinate system is a spatial rectangular coordinate system, and the origin of the spatial rectangular coordinate system is the location of the access network device, the network coverage determination apparatus may use a direction perpendicular to the horizontal plane upward as a z-axis direction of the spatial rectangular coordinate system, use a direction parallel to the horizontal plane eastward as an x-axis direction of the spatial rectangular coordinate system, and use a direction parallel to the horizontal plane northward as a y-axis direction of the spatial rectangular coordinate system.

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

In another possible implementation manner, when the type of the stereoscopic shape is a cube, the stereoscopic shape may be represented by the following formula:

A_j＝{ID₂,(x,y,z),a,b,c}；

wherein A is_jRepresenting the jth of at least one solid shape, ID₂The solid shape is a cube, (x, y, z) is the coordinate of the vertex of the cube closest to the origin of coordinates, a is the projection length of the cube on the x axis, b is the projection length of the cube on the y axis, c is the projection length of the cube on the z axis, and j is a positive integer.

In another possible implementation manner, when the type of the three-dimensional shape is an ellipsoid, the three-dimensional shape can be represented by the following formula:

A_j＝{ID₃,(x₀,y₀,z₀),g,h,k}；

wherein A is_jRepresenting the jth of at least one solid shape, ID₃Is of a type that the solid shape is ellipsoid, (x)₀,y₀,z₀) Is the central coordinate of the ellipsoid, g, h and k are the lengths of the half shafts of the ellipsoid, and j is a positive integer.

It should be noted that the network coverage determining apparatus may also represent other regular three-dimensional shapes such as a sphere, a cylinder, a cone, a ring body, etc. by the simplest mathematical quantity, which is not described in detail in the embodiments of the present application.

S2027, the network coverage determination device determines that the at least one parameter of the three-dimensional shape includes a type of the at least one three-dimensional shape and a coordinate parameter of the at least one three-dimensional shape in a preset spatial coordinate system.

Through the technical scheme, the network coverage determining device determines the preset space coordinate system, maps at least one determined three-dimensional shape into the preset space coordinate system, and expresses the specific position and 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, a detailed description is given of a process in which the network coverage determining apparatus determines the slice coverage area of the first network slice and determines 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.

Hereinafter, with reference to the above embodiments, a process of determining slice coverage in the first area and determining whether the service in the first area meets the requirement by the network coverage determination apparatus will be specifically described.

It should be noted that the following embodiments may be implemented in combination with the embodiment in fig. 2, the embodiment in fig. 3, and the embodiment in fig. 4. The following description will be given by taking fig. 2 as an example.

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

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

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

In one example, the first area may be a service coverage area of a service to be subscribed.

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 a slice coverage condition in the first area according to a coverage area of at least one access network device.

Wherein the slice coverage condition within the first region 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 a slice coverage area of each first network slice. Meanwhile, at least one access network device is included in the first area. Thus, the network coverage determining means may determine a coverage area of at least one access network device comprised within the first area.

In one possible implementation, the network coverage determining apparatus 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 apparatus takes 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 condition within the first area includes a slice coverage condition of each network slice within the first area.

Based on the above technical solution, the network coverage determining apparatus determines the slice coverage condition in the first area through the network coverage area of the access network device 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, with reference to the above embodiments, a process of the network coverage determining apparatus determining whether the service in the first area meets the requirement will be specifically described.

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

s304, the network coverage determining device determines the 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 means a working area of the user equipment corresponding to the service to be signed.

In a possible implementation manner, the ue is a ue that can move within a coverage area of a service to be subscribed.

In another possible implementation manner, the ue is a non-mobile ue that is located in a coverage area of the service to be subscribed.

In a possible implementation manner, the service coverage area of the service to be subscribed may be determined by a manner of the slice coverage area of the first network slice of the network coverage determination apparatus in step S202, or steps S2021 to S2022, or steps S2024 to S2027, please refer to the foregoing embodiment for details.

For example, the service coverage area of the service to be subscribed may be represented by the following formula:

US＝{B₁,B₂,B₃,B₄,B₅}；

wherein, US represents the service coverage area of the service to be signed, B₁,B₂,B₃,B₄,B₅The number of the three-dimensional shapes is 5, and the three-dimensional shapes are used for representing service coverage areas of services to be signed. The 5 solid shapes can be regular solid shapes or irregular solid shapes. The 5 solid shapes can be represented in the manner in steps S2024-S2027.

S305, the network coverage determination device determines a slice coverage area of the second network slice.

And 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 a network slice corresponding to the service to be subscribed, of the same type in the multiple access network devices in the first area.

In a possible implementation manner, the network coverage determining apparatus determines a QoS parameter requirement of the 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 apparatus 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. And the network coverage determining device takes the network slice in the first area which is the same as the QoS parameter mapped by the serial number of the network slice corresponding to the service to be signed as a second network slice.

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

NS₂＝{A₁,A₂,A₃,A₄}；

wherein NS₂Denotes a second network slice, A₁,A₂,A₃,A₄Is a solid shape of 4 slices covering the area for representing the second network slice. The 5 solid shapes can be regular solid shapes or irregular solid shapes. The 5 solid shapes can be represented in the manner in steps S2024-S2027.

And S306, under the condition 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 a possible implementation manner, after determining that the slice coverage condition in the first area meets the coverage requirement of the service to be signed, the network coverage determining apparatus may sign the service to be signed.

And S307, under the condition 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 determining that the slice coverage condition in the first area does not satisfy the coverage requirement of the service to be signed, the network coverage determining device may determine an uncovered slice coverage area according to the slice coverage condition in the first area and the service coverage area of the service to be signed, and determine the access network device construction target according to the uncovered slice coverage area.

In connection with the above example, the network coverage determining apparatus determines the service coverage area US of the service to be subscribed and the slice coverage area NS of the second network slice₂。

The network coverage determining device compares the service coverage area US of the service to be signed with the slice coverage area NS of the second network slice₂：

When US belongs to NS₂That is, when the slice coverage area of the second network slice includes 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 in use

That is, 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 satisfy the coverage requirement of the service to be signed, and calculates:

CS＝US-NS₂；

and the CS represents a coverage area which is not included by the slice coverage area sliced by the second network in the service coverage area of the service to be signed.

And the network coverage determining device determines the construction target of the access network equipment 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.
