Fig. 1 is a schematic architecture diagram of a mobile communication system suitable for use in an embodiment of the present application. As shown in fig. 1, the mobile communication system includes a network management device 110, a plurality of domain management devices (e.g., a domain management device 120 and a domain management device 130 in fig. 1), and a plurality of network devices (e.g., a network device 140 and a network device 150 in fig. 1). Fig. 1 is a schematic diagram, and the communication system may further include other network devices, such as a core network device, which is not shown in fig. 1. The embodiments of the present application do not limit the number of the domain management devices and the network devices included in the mobile communication system

The network management device is configured to manage a plurality of domain management devices, each of which is configured to manage one or more network devices connected thereto, network devices connected to the same domain management device belong to the same operator network, and a plurality of network devices connected to the same domain management device may belong to different areas.

The domain Management device may be a Sub Network Management Function (SNMF), a network slice sub network Management Function (NSSMF), an Element Management device (EM), a wireless Management device (mbe), or a Real-time intelligent control device (RIC).

The Network Management device may be a Network Slice Management Function (NSMF), a Service Organizer (SO), a Non-Real-Time Intelligent control (Non-RIC), or the like.

The network device may be a radio access network device, which is an access device that a terminal device accesses to the mobile communication system in a wireless manner, and may be a base station (base station), an evolved NodeB (eNodeB), a Transmission Reception Point (TRP), a next generation base station (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, and the like; the present invention may also be a module or a unit that performs part of the functions of the base station, and for example, the module may be a Centralized Unit (CU) or a Distributed Unit (DU). The embodiments of the present application do not limit the specific technology and the specific device form used by the radio access network device.

In the embodiments of the present application, the above-mentioned area may also be referred to as a physical area, a logical area, or a coverage area.

Network coverage and network capacity are key indexes for measuring network performance and are the most direct factors affecting the performance of the terminal device, and when a coverage problem exists in the network, the coverage problem can be usually handled by the network management device and the domain management device in fig. 1. A general method for optimizing the coverage problem of the network device and the domain management device is described below.

The coverage problem may also be referred to as a capacity problem, a coverage and capacity problem, or a coverage or capacity problem, and is not limited in this embodiment of the present application. Hereinafter, for convenience of description, it is referred to as a coverage problem.

FIG. 2 is a schematic interaction diagram of a general method 200 of optimizing coverage problems. The steps of method 200 are explained below.

S210, the domain management device collects the performance information of the network device.

The performance information of the network device collected by the domain management device may include, for example: reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), location information of the terminal device, handover-related parameters, and the like.

And S220, the domain management equipment reports the acquired performance information of the network equipment to the network management equipment.

S230, the network management device detects a coverage problem according to the received performance information.

S240, the network management device adjusts configuration parameters related to the network device according to the detected coverage problem.

The configuration parameters related to the network device may include azimuth angle, tilt angle, wave width, transmission power, etc.

And S250, the network management equipment sends the adjusted configuration parameters to the domain management equipment.

It can be seen that, in the method 200, since the data volume of the performance information reported by the domain management device is very large, each domain management device may not report very large data volume, and the performance information on different domain management devices may be different, in this case, the network management device may not be able to accurately detect the coverage problem in real time based on the performance information reported by the domain management device.

Secondly, in the method 200, for network devices managed by different domain management devices, the network management devices all adopt a general coverage problem optimization method to optimize the whole network. However, since the optimization of the coverage problem is related to the specific network device and the network environment, there may be differences between the network devices managed by different domain management devices, and at this time, if the network management device adopts a general coverage problem optimization method to optimize the entire network, the optimization effect may be poor.

In view of this, the embodiment of the present application provides a communication method, which can improve an optimization effect of network coverage.

Hereinafter, the communication method according to the embodiment of the present application will be described in detail with reference to fig. 3 to 5.

Fig. 3 is a schematic interaction diagram of a method 300 of communication provided by an embodiment of the application. Each step of the method 300 is described in detail below.

In the embodiment of the present application, the method 300 is described by taking a network management device (i.e., an example of the second device) and a domain management device (i.e., an example of the first device or an example of the third device) as an example of the execution subject of the method 300. By way of example and not limitation, the execution subject of executing the method 300 may also be a chip corresponding to the network management device and a chip corresponding to the domain management device.

In S310, the network management apparatus transmits an coverage problem monitoring policy including one or more discrimination conditions corresponding to one or more coverage problems to the domain management apparatus #1 (i.e., an example of the domain management apparatus). Accordingly, the domain management device obtains the coverage problem monitoring policy.

In S320, the domain management device #1 acquires the performance information #1 (i.e., an example of the first performance information) of the coverage object #1 (e.g., an example of the first coverage object), and determines the coverage problem (i.e., an example of the target coverage problem) existing in the coverage object #1 from the one or more coverage problems according to the coverage problem monitoring policy and the performance information # 1.

In S330, the domain management device #1 transmits coverage problem information (i.e., an example of first coverage problem information) of the coverage object #1 to the network management device. Accordingly, the network management apparatus receives the coverage problem information of the coverage object #1 transmitted by the domain management apparatus # 1.

In the embodiment of the present application, the coverage problem information is used to describe what coverage problem specifically exists in the coverage object. The coverage object may include any one of a cell, a beam, a network component, an area and a Tracking Area (TA). The network may refer to a sub-network, and the network component may refer to a network function module or a network device configured with the network function module.

For example, the coverage problem information is used to describe that there is a coverage interference problem between cell #1 and cell #2, or the coverage problem information is used to describe that there is a coverage hole problem in area #1, or the coverage problem information is used to describe that there is a mutual interference problem between cell #1, cell #2, and cell #3 in area #1, or the coverage problem information may also be used to describe that there is a coverage hole in TA #1, or the coverage problem information is used to describe that there is a coverage hole problem in network component # 1. It should be noted that the description of the coverage problem information herein is also applicable to the method 400 and the method 500 hereinafter, and for brevity, the description is not repeated hereinafter.

For example, in S320, when the coverage object #1 is the area #1 and the performance information #1 includes RSRP and RSRQ, the domain management device #1 acquires the performance information #1 of the coverage object #1, which may be the domain management device #1 acquiring RSRP and RSRQ of the network device #1 and RSRP and RSRQ of the network device #2 in the area # 1.

Here, the network device #1 and the network device #2 belong to network devices in the area #1 and are connected to the domain management device # 1. After the domain management device #1 acquires the performance information #1, the domain management device #1 determines the coverage problem existing in the area #1 from one or more coverage problems according to the coverage problem monitoring policy and the performance information #1, and sends the coverage problem information of the area #1 to the network management device, that is, reports the coverage problem existing in the area #1 to the network management device.

It should be noted that the one or more coverage problems may be predefined by a protocol, for example, the one or more coverage problems may be configured in advance when the domain management device is factory set, in this case, the coverage problem monitoring policy may include only one or more determination conditions, and when the domain management device #1 determines a coverage problem existing in the area #1, it may be determined which determination condition specifically corresponds to which coverage problem based on an association relationship between the coverage problem and the determination condition corresponding to the coverage problem.

For example, which determination condition specifically corresponds to which coverage problem may be determined based on identification information of each of the coverage problem and the determination condition, and for example, the coverage problem and the determination condition corresponding to the same identification information may be determined as a determination condition in which a set of coverage problems having a correspondence relationship with each other corresponds to the coverage problem.

In addition, when the domain management device #1 is factory set, one or more coverage problems may be configured in advance in the discrimination conditions corresponding to the one or more coverage problems, and in this case, the network management device may not issue the coverage problem monitoring policy to the domain management device # 1. That is, in concrete implementation, the step of the network management device transmitting the coverage problem monitoring policy to the domain management device #1 may not be necessary.

In one implementation, the network management device may adjust the network coverage related parameters (i.e., an example of the network coverage related parameters) of the coverage object #1 according to the received coverage problem information of the area # 1.

For example, when the coverage object #1 is the area #1, the network management device may adjust the network coverage related parameters of the coverage object #1 by adjusting the network coverage related parameters of the network device #1 and the network device #2 in the area #1, so as to optimize the network coverage of the area #1, that is, to solve the coverage problem existing in the area # 1.

In another implementation, the network management device may also optimize the network coverage optimization intent of area #1 by, for example:

s340, the network management device determines a network coverage optimization intention (i.e., an example of a first network coverage optimization intention) of the domain management device #1 according to the coverage problem information of the coverage object #1, where the network coverage optimization intention of the domain management device #1 is used for indicating a target of network coverage optimization that the domain management device #1 should implement.

For example, the network management apparatus may determine the network coverage optimization intention of the domain management apparatus #1 from the received coverage problem information of the area #1 (i.e., an example of the coverage object # 1).

S350, the network management device transmits the network coverage optimization intention of the domain management device #1 to the domain management device # 1. Accordingly, the domain management device #1 receives the network coverage optimization intention of the domain management device #1 transmitted from the network management device.

S360, the domain management device #1 adjusts the network coverage related parameters of the coverage object #1 according to the network coverage optimization intention of the domain management device # 1.

In one implementation, the network coverage optimization intention of the domain management device #1 includes coverage problem information of the area #1 (i.e., an example of the coverage object # 1), for example, if the network coverage optimization intention of the domain management device #1 indicates that the coverage hole problem of the area #1 is eliminated, it may be clear that the coverage problem information of the area #1 indicates that the area #1 has the coverage hole problem, and at this time, when the network coverage of the area #1 is optimized, the domain management device #1 does not need to additionally acquire the coverage problem information of the area #1, and the network coverage of the area #1 may be optimized only according to the network coverage optimization intention of the domain management device # 1.

In another implementation, when the network coverage optimization intention of the domain management device #1 only includes the coverage problem and does not include the coverage object, in this case, the domain management device #1 needs to further combine the coverage problem information, that is, process the coverage problem existing in the coverage object according to the network coverage optimization intention and the coverage problem information.

For example, the network coverage optimization intention of the domain management device #1 only indicates to eliminate the over-coverage problem, and at this time, the domain management device #1 needs to determine whether the over-coverage problem exists in the area or the over-coverage problem exists in the cell in combination with the coverage problem information, for example, if the domain management device #1 determines that the over-coverage problem exists in the area #1, the domain management device #1 finally determines to process the over-coverage problem existing in the area #1 according to the network coverage optimization intention and the coverage problem information.

The above S320 may be specifically implemented by the following manner: the domain management apparatus #1 determines the coverage problem corresponding to the discrimination condition satisfied by the performance information #1 as the coverage problem existing in the region #1, based on the discrimination condition for the performance information #1 corresponding to the coverage problem.

For example, the coverage problem may include a weak coverage (weak coverage) problem (for example, coverage of a certain area is less than a planned coverage requirement), a coverage hole (coverage hole) problem (for example, a certain area is not covered), an over coverage (over coverage) (coverage of a cell or a beam in a certain area exceeds a planned coverage, which may cause interference with other cells or beams), a pilot pollution (pilot pollution) problem (for example, coverage overlap between different cells or beams in a certain area is severe, which causes problems such as interference or call drop, etc.), a terminal equipment (user equipment, UE) hot spot area (hotspot area) problem (for example, a certain area cell coverage boundary or a beam coverage boundary is a terminal equipment hotspot area, which causes frequent switching of the boundary position) and uplink (uplink) and downlink (downlink) coverage mismatch (downlink) problem (for example, downlink coverage is greater than uplink coverage).

The discrimination condition corresponding to the coverage problem may include one or more of a pilot signal strength threshold, a signal to interference noise ratio (SINR) threshold, an RSRQ threshold, an RSRP threshold, a coverage overlap region cell number threshold, an interference level threshold, a cell switching frequency threshold, a cell switching number threshold, a Radio Resource Control (RRC) connection status, a Physical Resource Block (PRB) usage threshold, and an uplink coverage interference power threshold.

The performance information #1 may include RSRP, RSRQ, Random Access Channel (RACH) usage related measurement quantity, power utilization measurement quantity (e.g., maximum carrier transmission power or average carrier transmission power), channel quality information (channel quality information distribution), distribution-related measurement quantity (e.g., average subband CQI distribution measurement quantity), terminal device transmission power space (UE power head, UPH), RRC connection-related measurement quantity (e.g., RRC establishment success rate, RRC establishment failure rate, UE CONTEXT (CONTEXT) release request quantity, UE ext release success quantity, or success rate), Radio Access Bearer (RAB) bearer measurement quantity, PRB usage related measurement quantity (e.g., PRB release quantity), downlink PRB usage or usage), Radio Link Failure (RLF), location (location) related information (e.g., one or more of Cell identity (Cell Id), Tracking Area (TA), global navigation satellite system (global navigation satellite system) information), and uplink interference power (UL interference power).

It should be noted that, in the embodiment of the present application, the performance information is related to the coverage object, for example, when the coverage object is a cell, the performance information includes performance information of at least one cell; when the coverage object is an area, the performance information includes performance information of network devices within the at least one area.

For example, the discrimination conditions corresponding to the coverage hole problem include: a coverage hole pilot signal strength threshold, a coverage hole SINR threshold, a coverage hole level threshold and the like; the discrimination conditions corresponding to the weak coverage problem include: a weak coverage pilot signal strength threshold, a weak coverage SINR threshold, a weak coverage level threshold, etc.; the judgment condition corresponding to the over-coverage problem comprises the following steps: an over-coverage level threshold, an over-coverage RSRP threshold, an over-coverage SINR threshold, and a coverage overlap region threshold; the judgment conditions corresponding to the pilot pollution problem comprise: pilot pollution covers SINR threshold, covers the number of cells in the overlapping area, interferes with the level threshold; the discrimination conditions corresponding to the problem of the hot spot area of the terminal equipment comprise: cell switching frequency or times, covering signal-to-interference ratio threshold; the discrimination conditions corresponding to the problem of uplink and downlink coverage mismatching include: and uplink coverage interference power.

When identifying a coverage problem in the area #1, the area management apparatus #1 may analyze the performance information #1 associated with the area #1, determine whether the performance information #1 satisfies a determination condition corresponding to the coverage problem, and identify the coverage problem corresponding to the determination condition satisfied by the performance information #1 as the coverage problem in the area # 1.

For example, when the discrimination condition corresponding to the over-coverage problem is an over-coverage RSRP threshold, the domain management device #1 may determine whether RSRP in the performance information #1 is greater than the over-coverage RSRP threshold, and if RSRP in the performance information #1 is greater than the over-coverage RSRP threshold, the domain management device #1 may determine that the coverage problem existing in the domain #1 is the over-coverage problem.

When the domain management device #1 determines that the coverage problem exists in the area #1, the above S330 may be specifically implemented as follows:

for example, when reporting the coverage problem of the area #1 to the network management device, if there is more than one coverage problem of the area #1, for example, when the area #1 has both the over-coverage problem and the pilot pollution problem, the area management device #1 may report the over-coverage problem and the pilot pollution problem of the area #1 to the network management device as a whole, or the area management device #1 may report the over-coverage problem and the pilot pollution problem of the area #1 to the network management device in sequence.

If the domain management device #1 determines that the coverage problem of another area (e.g., the area #2) is the same as the area #1, for example, if the domain management device #1 determines that the coverage problem of the area #2 is also the same, the domain management device #1 may report the coverage problems of the area #2 and the area #1 to the network management device as a whole, or the domain management device #1 may report the coverage problem of the area #1 and the coverage problem of the area #2 to the network management device in sequence.

The above S340 may be specifically implemented in the following manner: the network management device determines the network coverage optimization intention of the domain management device #1 according to the coverage problem existing in the domain # 1.

The network coverage optimization described above is intended to describe the goals or effects of coverage optimization. The coverage optimization target may include one or more of no coverage hole, no over coverage, no coverage interference, no weak coverage, a weak coverage proportion threshold, an over coverage proportion threshold, a coverage hole threshold, an uplink and downlink coverage mismatch cell proportion threshold, a pilot pollution coverage area proportion threshold, an over coverage cell proportion threshold, and a weak coverage cell proportion threshold. For example, the coverage problem existing in the domain management device #1 is a weak coverage problem, and the network management device determines that the network coverage optimization intention of the domain management device #1 is 10% from the weak coverage problem existing in the area #1, where 10% may be the maximum value of the allowed weak coverage ratio, i.e., such that the weak coverage ratio of the optimized area #1 is less than 10%.

In addition, the network coverage optimization is intended to describe the goal or effect of coverage optimization, and may further indicate the object that achieves the goal or effect, for example, the no-coverage hole in the goal of coverage optimization may be further refined into no-coverage hole in a cell, and the no-coverage may be further refined into no-coverage in an area.

For example, the coverage problem existing in the area #1 is a coverage interference problem, and the network management device determines that the network coverage optimization of the area management device #1 intends to eliminate the coverage interference of the area #1 according to the coverage interference problem existing in the area # 1. In an actual scenario, there may be at least two coverage problems in the area #1 at the same time, and the network management device needs to combine all the coverage problems to give the network coverage optimization intention of the area management device # 1.

For example, the area #1 has both the problem of the over-coverage and the problem of the coverage interference, and the network management device determines that the network coverage optimization intention of the area #1 is 20% of the over-coverage proportion threshold of the area #1 according to the problem of the coverage and the problem of the coverage interference existing in the area #1, and eliminates the coverage interference of the area # 1.

The above S340 may be specifically implemented by the following method: the network management device determines the network coverage optimization intention of the domain management device #1 from the coverage problem information of the area #1 and the traffic data (i.e., the traffic data related to the first coverage object) related to the area # 1.

For example, when determining the network coverage optimization intention of the domain management device #1, the network management device may determine the network coverage optimization intention of the domain management device #1 in combination with a traffic model, a call drop rate, a user distribution, user subscription data, and the like (for example, an example of traffic data related to the domain # 1) in the domain #1, in addition to determining the network coverage optimization intention of the domain management device #1 according to the coverage problem information of the domain # 1.

The service traffic model of the area #1 is used to describe the traffic volume of the area #1, and the network management device may determine the network coverage optimization intention of the area management device #1 according to the coverage problem information of the area #1 and the service traffic model of the area # 1. For example, the coverage problem existing in the area #1 is a coverage hole problem, and at this time, if the traffic model of the area #1 indicates that the area #1 has no traffic, the network management device may not determine a network coverage optimization intention for the area #1, that is, determine not to optimize the network coverage of the area #1, that is, not to process the coverage hole problem existing in the area # 1.

If the service traffic model of the area #1 indicates that a certain amount of traffic exists in the area #1, the network management device may determine, according to the coverage hole problem existing in the area #1 and the service traffic model of the area #1, that the network coverage optimization of the area management device #1 intends to eliminate the coverage hole of the area # 1. The network management device can also determine the network coverage optimization intention of the domain management device #1 according to the coverage problem existing in the domain #1 and the user distribution situation of the domain # 1.

For example, the coverage problem existing in the area #1 is a weak coverage problem, and at this time, if the user distribution condition of the area #1 indicates that the area #1 has no user distribution, the network management device may not determine the network coverage optimization intention for the area #1, i.e., determine not to optimize the network coverage of the area #1, i.e., not to deal with the weak coverage problem existing in the area # 1.

If the user distribution situation of the area #1 indicates that the area #1 is distributed with a certain number of users, the network management device may determine, according to the weak coverage problem existing in the area #1 and the user distribution situation of the area #1, that the network coverage optimization intention of the area management device #1 is such that the weak coverage proportion of the area #1 is < 5%, or that the weak coverage proportion of the area #1 is < 10%, or that the weak coverage of the area #1 is eliminated.

The network management device transmits the determined network coverage optimization intention of the domain management device #1 to the domain management device #1, and after the domain management device #1 receives the network coverage optimization intention of the domain management device #1, the above S360 may be specifically implemented by:

the domain management device #1 adjusts the network coverage related parameters of the network device #1 and the network device #2 according to the network coverage optimization intention of the domain management device # 1.

For example, the above-mentioned parameters related to the network device #1 and the network device #2 may include one or more of azimuth angle, tilt angle, horizontal wave width, vertical wave width, transmission power, antenna pattern, and beam pattern. For example, the network coverage optimization of the domain management device #1 is intended to make the weak coverage ratio threshold 10%, where 10% may be the maximum value of the allowed weak coverage ratio, and the domain management device #1 may adjust the network coverage related parameters (e.g., transmission power and antenna pattern) of the network device #1 and the network device #2 in order to make the weak coverage ratio of the region #1 < 10% after adjustment.

When the domain management device #1 adjusts the network coverage related parameters of the network device #1 and the network device #2, the adjusted parameters may be transmitted to the network device #1 and the network device #2, and the network device #1 and the network device #2 may optimize the network coverage of the domain #1 according to the received adjusted parameters.

When the network device leaves the factory, different network coverage related parameters may be configured for the network device according to different scenarios (e.g., an indoor scenario, an outdoor scenario, a high-speed rail scenario, and a square scenario). Therefore, when optimizing the network coverage of the area #1, the domain management device #1 may further send scene information (e.g., scene number 1, 2, or 3) to the network device, and the network device determines a network coverage related parameter corresponding to the scene information according to a pre-configured correspondence between the scene information and the network coverage related parameter, and then optimizes the network coverage of the area #1 according to the determined network coverage related parameter.

The azimuth, the tilt angle, the horizontal bandwidth, the vertical bandwidth, and the transmission power may be an antenna azimuth or a beam azimuth, an antenna tilt angle or a beam tilt angle, an antenna horizontal bandwidth or a beam horizontal bandwidth, an antenna vertical bandwidth or a beam vertical bandwidth, an antenna transmission power, or a beam transmission power, respectively.

It should be noted that, if there are at least two domain management devices (e.g., domain management device #1 and domain management device #2 (i.e., an example of a third device)) reporting coverage problem information to the network management device including the same coverage problem, for example, when the domain management device #1 reports the coverage hole problem of the area #1 (i.e., an example of the first coverage problem information) to the network management device, and the domain management device #2 reports the coverage hole problem of the area #2 (i.e., an example of the second coverage problem information) to the network management device, the network management device may determine, based on the overlapping situation between the area #1 and the area #2, a network coverage optimization intention to be transmitted to the domain management device #1 (which may also be referred to as the network coverage optimization intention of the domain management device # 1) and a network coverage optimization intention transmitted to the domain management device #2 (which may also be referred to as the network coverage optimization intention of the domain management device # 2) are determined. The network coverage optimization intention to be transmitted to the domain management device #1, which is determined by the network management device, is explained below with respect to several overlapping cases of the region #1 and the region # 2.

In case #1, region #1 completely overlaps region # 2.

In this case, the network management apparatus may transmit the network coverage optimization intention to any one of the domain management apparatus #1 and the domain management apparatus #2, and optimize the network coverage of the area #1 or the area #2 by any one of the domain management apparatus #1 and the domain management apparatus # 2. At this time, the network coverage optimization intention transmitted from the network management apparatus to the domain management apparatus #1 in S350 is used to instruct the domain management apparatus #1 to the target to be achieved when optimizing the network coverage of the area # 1.

Case #2, region #1 partially overlaps region # 2.

In this case, for the overlapping area of the area #1 and the area #2, the network management apparatus may transmit the network coverage optimization intention of the overlapping area of the area #1 and the area #2 to the domain management apparatus #1, and the network coverage of the overlapping area of the area #1 and the area #2 is optimized by the domain management apparatus # 1; for the non-overlapping areas of the area #1 and the area #2, the network management apparatus may transmit the network coverage optimization intention of the non-overlapping areas of the area #1 and the area #2 to the domain management apparatus #2, and optimize the network coverage of the non-overlapping areas of the area #1 and the area #2 by the domain management apparatus # 2. At this time, the network coverage optimization intention transmitted by the network management apparatus to the domain management apparatus #1 in S350 is for instructing the domain management apparatus #1 to achieve a target to be achieved when optimizing the network coverage of the overlapping area of the area #1 and the area # 2.

In case #3, the area #1 and the area #2 do not overlap at all.

In this case, for the area #1, the network management apparatus may transmit the network coverage optimization intention of the area management apparatus #1 to the area management apparatus #1, the network coverage of the area #1 being optimized by the area management apparatus # 1; for the area #2, the network management apparatus may transmit the network coverage optimization intention of the area management apparatus #2 to the area management apparatus #2, and the network coverage of the area #2 is optimized by the area management apparatus # 2. At this time, the network coverage optimization intention transmitted by the network management apparatus to the domain management apparatus #1 in S350 is used to instruct the domain management apparatus #1 to achieve the target to be achieved when optimizing the network coverage of the area # 1.

In the embodiment of the present application, after a certain domain management device (e.g., the domain management device #1) optimizes the network coverage of a corresponding area (e.g., the area #1), it may be further determined whether the network coverage of the optimized area satisfies a corresponding network coverage optimization intention (e.g., the network coverage optimization intention of the domain management device # 1). For example:

s370, the domain management device #1 acquires the capability information #2 (i.e., an example of the second capability information) covering the object # 1.

S380, the domain management device #1 determines whether the optimized coverage problem existing in the coverage object #1 satisfies the network coverage optimization intention of the domain management device #1 according to the performance information #2 and the coverage problem monitoring policy.

For example, the domain management device #1 continues to collect the performance information #2 of the network device #1 and the network device #2 in the area #1 (i.e., an example of the coverage object # 1), and determines again the coverage problem existing in the current area #1 according to the coverage problem monitoring policy, and the domain management device #1 determines whether the network coverage optimization intention of the domain management device #1 is satisfied according to the determined coverage problem existing in the current area #1, and if not, continues to perform S370 until the network coverage optimization intention of the domain management device #1 is satisfied.

It should be noted that for the specific explanation of the performance information #2, reference is made to the relevant explanation of the performance information #1 in the method 300, and details are not repeated herein for brevity.

The method 300 provided by the embodiment of the present application is described in detail above with reference to fig. 3, and another method 400 provided by the embodiment of the present application is described below. Fig. 4 is a schematic interaction diagram of another method 400 of communication provided by an embodiment of the application. Each step of the method 400 is explained below.

In the embodiment of the present application, the method 400 is described by taking a network management device (i.e., an example of the second device) and a domain management device (i.e., an example of the first device or the third device) as an example of the execution subject of the method 400. By way of example and not limitation, the execution subject of executing the method 400 may also be a chip corresponding to the network management device and a chip corresponding to the domain management device.

In S450, the network management device transmits, to the domain management device #1 (e.g., an example of a domain management device), a network coverage optimization intention (i.e., an example of a first network coverage optimization intention) of the domain management device #1, the network coverage optimization intention of the domain management device #1 indicating a target of network coverage optimization that the domain management device #1 should achieve. Accordingly, the domain management device acquires the network coverage optimization intention of the domain management device # 1.

In S460, the domain management device #1 adjusts the network coverage related parameter (i.e., an example of the network coverage related parameter) of the coverage object #1 according to the network coverage optimization intention of the domain management device # 1.

It should be noted that, for the specific implementation of S460, reference is made to the related description of S360 in the method 300, and details are not repeated here for brevity.

In S460, when the domain management device #1 needs to optimize the network coverage of the area #1 in combination with the network coverage optimization intention of the domain management device #1 and the coverage problem information of the area #1 (i.e., an example of the coverage object # 1), the domain management device #1 can determine the coverage problem existing in the area #1 by the following acquisition.

In one implementation, the coverage problem existing in the area #1 may be determined by the network management device according to the related description as in the method 200, and then the determined coverage problem existing in the area #1 is transmitted to the domain management device #1 by the network management device.

In another implementation, for example:

s410, the network management device sends a coverage problem monitoring policy to the domain management device #1, the coverage problem monitoring policy including one or more discrimination conditions for each coverage problem corresponding to the coverage problem. Accordingly, the domain management device #1 acquires the coverage problem monitoring policy.

S420, the domain management device #1 acquires the performance information #1 (i.e., an example of the first performance information) of the coverage object #1, and determines the coverage problem existing in the coverage object #1 from the one or more coverage problems according to the coverage problem monitoring policy and the performance information # 1.

For the specific implementation of S420, please refer to the related description of S320 in the method 300, and for brevity, the description is omitted here.

It should be noted that, in the method 400, the network coverage optimization intention of the domain management device #1 may be determined by the network management device itself, or the network management device may be determined according to the coverage problem information of the area #1 after receiving the coverage problem information of the area #1 reported by the domain management device #1, and send the determined network coverage optimization intention of the domain management device #1 to the domain management device # 1.

If the network coverage optimization intention of the domain management device #1 is determined by the network management device based on the coverage problem information of the area #1 reported by the domain management device #1, in this case, the method 400 may further include:

S430, the domain management device #1 transmits coverage problem information of the coverage object #1 to the network management device. Accordingly, the network management apparatus receives the coverage problem information of the coverage object #1 transmitted by the domain management apparatus # 1.

S440, the network management device determines the network coverage optimization intention of the domain management device #1 according to the coverage problem information of the coverage object # 1.

In the embodiment of the present application, the method 500 is described by taking a network management device (i.e., an example of the second device) and a domain management device (i.e., an example of the first device) as an example of the execution subject of the method 500. By way of example and not limitation, the execution subject of executing the method 500 may also be a chip corresponding to the network management device and a chip corresponding to the domain management device.

In S540, the network management device transmits, to the domain management device #1 (i.e., an example of the domain management device), a network coverage optimization task including a network coverage optimization intention (i.e., an example of a first network coverage optimization intention) of the domain management device #1 and an coverage problem monitoring policy, the network coverage optimization intention of the domain management device #1 indicating a target of network coverage optimization that the domain management device #1 should implement, the coverage problem monitoring policy including a discrimination condition corresponding to one or more coverage problems. Accordingly, the domain management device #1 acquires the coverage optimization task.

In S550, the domain management device #1 adjusts the network coverage related parameter (i.e., an example of the network coverage related parameter) of the coverage object #1 according to the network coverage optimization intention of the domain management device # 1.

It should be noted that, for concrete implementation of S550, reference is made to the related description of S360 in the method 300, and for brevity, description is not repeated here.

It should be noted that, in the method 500, the network coverage optimization intention of the domain management device #1 may be determined by the network management device itself, or the network management device may be determined according to the coverage problem information of the area #1 after receiving the coverage problem information of the area #1 reported by the domain management device #1, and send the determined network coverage optimization intention of the domain management device #1 to the domain management device # 1.

The network management device may determine the network coverage optimization intention of the domain management device #1 by, for example:

s510, the domain management device #1 acquires the performance information #1 (i.e., an example of the first performance information) of the coverage object #1, and determines the coverage problem (i.e., an example of the target coverage problem) existing in the coverage object #1 from the one or more coverage problems according to the coverage problem monitoring policy and the performance information # 1.
