[0108] For ease of understanding, the technical terms involved in the embodiments of the present application are first introduced below.

[0109] 1. Network system

[0110] Figure 1 It is a schematic diagram of the network system architecture, such as Figure 1 As shown, the network system architecture includes: third party, operation administration and maintenance (OAM), radio access network (RAN) network elements, and core network (CN) network elements.

[0111] The third party may also be referred to as a third-party management controller or a third-party management system, which may be used to manage and control the terminal. For example, the third party may be an unmanned aircraft system traffic management (UTM), an unmanned aerial vehicle (UAV) operator, or an uncrewed aerial system (UAS).

[0112] The terminal may also be referred to as user equipment (UE), access terminal, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal equipment, wireless communication device, user agent or user device. The terminal in the embodiments of the present application can be a mobile phone, a cellular phone, a smart phone, a tablet computer, a wireless data card, a personal digital assistant (PDA), a wireless modem, a handset, a laptop computer, a machine type communication (MTC) terminal, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a vehicle-mounted terminal, a road side unit (RSU) with terminal function, etc. The terminal device of the present application may also be a vehicle-mounted module, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip or a vehicle-mounted unit built into a vehicle as one or more components or units. The terminal device may also be other devices having terminal device functions, for example, the terminal device may also be a device that functions as a terminal device in D2D communication.

[0113] The embodiments of the present application do not limit the form of the terminal device. The device for realizing the function of the terminal device can be the terminal device; it can also be a device that can support the terminal device to realize the function, such as a chip system. The device can be installed in the terminal device or used in combination with the terminal device. In the embodiments of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0114] For example, when the drone uses the 3rd generation partnership project (3GPP) network as the access type, the UTM (or UAV operator, or UAS) may need to use the 3GPP network to confirm the network status for flight path scheduling. The 5G system can assist the UTM or UAV operator to provide alternative flight paths based on the quality of service (QoS) supported in a specific area, or reconfigure network resources to achieve the required QoS.

[0115] For example, Figure 2 As shown in the figure, company #1 plans to use drone A to conduct video inspection of the pipeline from X to Y, and company #2 uses drone B to deliver express from X to Z; drone A and drone B are registered in the 5G network and can communicate with UTM through the 5G network; UTM obtains the planned flight route information of drone A, such as the starting point X, the end point Z, and the required quality of experience (QoE); UTM and the 5G system determine the QoS information required along the flight path of the drone service, such as end-to-end delay, quality of experience (QoE), etc.; based on the available analysis information, the 5G system can ensure that the service quality on the flight path of drone A meets the requirements, or reconfigure network resources to provide the required QoS to drone A along the flight path, or re-plan the route for drone A to achieve better service guarantee; UTM (or UAS) determines the final flight route based on the information fed back by the 5G network and informs drone A; drone A receives the flight path information from UTM (or UAS) through the 5G system and starts the flight mission.

[0116] The above OAM network elements are used to complete the analysis, prediction, planning and configuration of daily networks and services, as well as daily operations such as testing and fault management of networks and their services. They include network management system (NMS), domain management system (EMS)-RAN, EMS-CN. NMS can also be called a cross domain management system, which can manage multiple single domain management systems. EMS can manage single domain network elements, such as RAN network elements, CN network elements, etc.

[0117] The above-mentioned RAN may be a device that provides access to a terminal device. For example, the RAN device may include: a next-generation mobile communication system, such as an access network device of 6G, such as a 6G base station, or in the next-generation mobile communication system, the network device may also have other naming methods, which are all included in the protection scope of the embodiments of the present application, and the present application does not impose any restrictions on this. Alternatively, the RAN device may also include 5G, such as a gNB in ​​a new radio (NR) system, or one or a group of (including multiple antenna panels) antenna panels of a base station in 5G, or a network node constituting a gNB, a transmission point (transmission and reception point, TRP or transmission point, TP) or a transmission measurement function (transmission measurement function, TMF), such as a baseband unit (building baseband unit, BBU), or a centralized unit (centralized unit, CU) or a distributed unit (distributed unit, DU), an RSU with a base station function, or a wired access gateway, or a 5G core network. Alternatively, RAN equipment may also include access points (APs) in wireless fidelity (WiFi) systems, wireless relay nodes, wireless backhaul nodes, various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, wearable devices, vehicle-mounted devices, and the like.

[0118] The above CN is mainly responsible for maintaining the subscription data of the mobile network and providing functions such as session management, mobility management, policy management and security authentication for terminal devices. CN mainly includes the following: user plane function (UPF), authentication server function (AUSF), access and mobility management function (AMF), session management function (SMF), network slice selection function (NSSF), network exposure function (NEF), network repository function (NRF), policy control function (PCF), unified data management (UDM), unified data repository (UDR), application function (AF), and sensing function (SF).

[0119] As wireless network coverage increases, terminals can use wireless networks while moving. During the movement of the terminal, the location of the terminal and each base station changes. For example, if the terminal is far away from each base station, the network quality of the terminal cannot be guaranteed while moving.

[0120] Therefore, how to ensure the network quality of the terminal when it is moving is a hot topic of discussion.

[0121] In response to the above technical problems, the embodiments of the present application propose the following technical solutions to ensure the network quality when the terminal is moving.

[0122] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0123] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, fifth generation (5G) mobile communication systems, such as new radio (NR) systems, and communication systems evolved after 5G, such as sixth generation (6G) mobile communication systems, and can also be applied to wireless fidelity (WiFi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, etc.

[0124] The present application will present various aspects, embodiments or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. In addition, combinations of these schemes may also be used.

[0125] In addition, in the embodiments of the present application, words such as "exemplary" and "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present concepts in a concrete way.

[0126] In the embodiments of the present application, "information", "signal", "message", "channel" and "signaling" can sometimes be used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings to be expressed are matched. "of", "corresponding, relevant" and "corresponding" can sometimes be used interchangeably. It should be noted that when the distinction between them is not emphasized, the meanings to be expressed are matched. In addition, the " / " mentioned in the present application can be used to express an "or" relationship.

[0127] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0128] To facilitate understanding of the embodiments of the present application, first Figure 3 The communication system shown in the example is used to describe in detail the communication system applicable to the embodiment of the present application. Figure 3 A schematic diagram of the architecture of a communication system applicable to the communication method provided in an embodiment of the present application.

[0129] The communication system includes: a management service consumer and a first management service providing entity. The management service consumer is the caller of the management service and can request to call the management service provided by the management service providing entity. The first management service providing entity is responsible for providing management services and receiving requests from the management service consumer. The communication system can be applied to the above-mentioned management system architecture. In this case, the management service consumer can be a third-party management system, and the first management service providing entity can be deployed on EMS-RAN and EMS-CN, or on NMS.

[0130] Optionally, the communication system may further include a second management service provider entity, which may provide management services, such as simulating the region by establishing a network twin model, and rehearsing management strategies on the network twin model to estimate the service assurance satisfaction of the region under different management strategies, wherein the simulation objects may include the regional environment, such as block structure, weather, buildings, etc., the regional network, and the communication equipment that provides the network for this region, etc. In this case, the management service consumer may be a third-party management system, and the second management service provider entity may be deployed on the NMS, EMS-RAN, and EMS-CN.

[0131] It is understandable that Figure 3 As shown, when the communication system includes a management service consumer and a first management service providing entity, the first management service providing entity can be Figure 3 When the communication system includes a management service consumer, a first management service provider, and a second management service provider, the management service consumer and the first management service provider may correspond to Figure 3 The management service consumer and the management service provider entity in the management service provider entity, the first management service provider entity and the second management service provider entity may also correspond to Figure 3 The management service consumer and the management service providing entity in the management service provider, that is, the first management service providing entity is the management service consumer of the second management service providing entity.

[0132] It can also be understood that the "management service consumer" mentioned in the embodiment of the present application is only an exemplary expression, and the "management service consumer" can also be replaced by any possible expression, such as "third party" or "third-party management system", etc., without limitation. The "management service providing entity" mentioned in the embodiment of the present application is only an exemplary expression, and the "management service providing entity" can also be replaced by any possible expression, such as "business assurance service provider" or "management service provider", etc., without limitation.

[0133] In a communication system, a management service consumer may send a first message to a first management service provider for requesting network performance requirements to guarantee the communication service quality when moving along a first route within a first time, so that the first management service provider configures network resources by triggering a configuration network resource reservation strategy, so that the terminal can use the network resources when moving along the first route within the first time. In this way, the network quality when the terminal moves can be guaranteed.

[0134] Understandably, Figure 3 The simplified schematic diagram is provided for ease of understanding. The communication system may also include other network devices and / or other terminal devices. Figure 3 Not drawn.

[0135] For ease of understanding, the following will combine Figure 4 The communication method provided in the embodiments of the present application is specifically described.

[0136] For example, Figure 4 A flow chart of a communication method provided in an embodiment of the present application. The method can be applied to the communication between the management service consumer and the first management service providing entity in the above communication system.

[0137] like Figure 4 As shown, the process of the communication method is as follows:

[0138] S401: A management service consumer sends a first message to a first management service provider. Correspondingly, the first management service provider receives the first message from the management service consumer.

[0139] The first message is used to request to ensure the quality of communication service when moving along the first route within a first time according to network performance requirements.

[0140] The network performance requirements are the requirements of the management service consumer for the network performance of the communication service when the terminal moves, such as throughput requirements, latency requirements, etc. The first time is the time when the quality of the communication service needs to be guaranteed, which can be the time when the terminal is expected to move, or can include the time when the terminal is expected to move, for example: the terminal is expected to move at 9:00-10:00, then the first time can be 9:00-10:00, or 8:00-10:00, or 8:30-10:00. The first time can be flexibly set according to actual conditions without restriction. The first route is the route that the terminal is expected to move, which can be flexibly set according to actual conditions without restriction. It can be understood that the terminals in the embodiments of the present application are all terminals that can be managed by management service consumers.

[0141] Optionally, the first message may include at least one of the following: information indicating the first time, or information indicating the first route.

[0142] The information used to indicate the first time may include the start time and the end time. For example, if the time for conducting the service assurance satisfaction evaluation for the first area is 14:00-15:00, the information used to indicate the first time includes the start time 14:00 and the end time 15:00. The information may also include the start time and the evaluation time period. Continuing with the example, in this case, the information used to indicate the first time includes the start time 14:00 and the evaluation time period 1 hour (h).

[0143] The information used to indicate the first route may include multiple coordinate points, that is, the first route is composed of multiple coordinate points, such as connecting the multiple coordinate points in sequence to obtain the first route; it may also be a bit value corresponding to the route agreed upon by the management service consumer and the first management service providing entity, for example: the first management service providing entity pre-sets route #1, route #2, route #3 and route #4, and routes #1 to route #4 correspond to bits 00, 01, 10 and 11 respectively. If the first route is route #1, the information used to indicate the first route is 00. The information used to indicate the first route may also be represented in other ways, without limitation.

[0144] The management service consumer can flexibly determine the first time and / or the first area according to actual conditions, and send the first time and / or the first area to the first management service provider entity, so that the first management service provider entity can reserve network resources based on the first time and / or the first area. It can be understood that when the first time or the first area is preset in the first management service provider entity, the first message may not include information for indicating the first time or information for indicating the first route. In other words, if the first message does not include information for indicating the first time or information for indicating the first route, it can indicate that the information for indicating the first time or the information for indicating the first route has been preset in the first management service provider entity.

[0145] Optionally, the first message may include at least one of the following: route planning instructions, network performance requirements, evaluation precision requirements, slice identifiers, policy adjustment parameters, or optimization stop conditions.

[0146] The route planning instruction can be used to indicate whether a mobile route needs to be provided, that is, when a mobile route needs to be provided, the route planning instruction can be used to indicate that a mobile route needs to be provided; otherwise, the route planning instruction can be used to indicate that a mobile route does not need to be provided. The route planning instruction can also be used to indicate that a mobile route needs to be provided, that is, when a route planning instruction is included in a message, it indicates that a mobile route needs to be provided; when a route planning instruction is not included in a message, it indicates that a mobile route does not need to be provided.

[0147] It can be understood that when the route planning indication is used to indicate whether a mobile route needs to be provided, different bits can be used to indicate different situations of the route planning indication, for example: bit 0 is used to indicate that a mobile route needs to be provided, and bit 1 is used to indicate that a mobile route does not need to be provided. That is, when the parameter value of the information element used to indicate the route planning indication in the first message is 0, it can indicate that a mobile route needs to be provided. When the parameter value of the information element used to indicate the route planning indication in the first message is 1, it can indicate that a mobile route does not need to be provided.

[0148] It can also be understood that in an embodiment of the present application, the route planning indication is used to indicate that it is not necessary to provide a mobile route. Therefore, when the route planning indication is used to indicate whether it is necessary to provide a mobile route, the first message includes a route planning indication for indicating that it is not necessary to provide a mobile route, and when the first management service provider entity receives the first message including the route planning indication, it can be determined that it is not necessary to provide a mobile route based on the route planning indication. Alternatively, when the route planning indication is used to indicate that it is necessary to provide a mobile route, the first message does not include the route planning indication, and when the first management service provider entity receives the first message, it can be determined that it is not necessary to provide a mobile route based on the fact that the route planning indication is not included in the first message. When the first management service provider entity determines that it is not necessary to provide a mobile route, it can reserve network resources for the management service consumer to ensure the network quality of the terminal when it is moving.

[0149] For network performance requirements, please refer to the above related introduction and will not be repeated here.

[0150] The evaluation precision requirement is used to indicate the size of multiple grids constituting the area of ​​the coverage route. For example, when the route is a route in a flat area, the evaluation precision requirement can be the length and width of multiple grids, or the area, such as: the evaluation precision is 1 meter (m) in length and 1m in width; or the evaluation precision is 1 square meter (m 2 ). When the route is a route in a three-dimensional area (three-dimensional space), the evaluation precision requirement can be the length, width and height of multiple grids, or volume, for example: the evaluation precision is 1 meter (m) in length, 1m in width, and 1m in height; or the evaluation precision is 1 cubic meter (m 3 ). It can be understood that when the first message includes the evaluation fineness requirement, the evaluation fineness requirement is used to indicate the sizes of the multiple first grids constituting the area covering the first route.

[0151] The slice identifier is used to indicate the network slice used to reserve network resources, which can be a slice identifier. It can be understood that the first message can include the slice identifier on the premise that the management service consumer has reached an agreement with the network operator on the slice service, that is, the management service consumer can know the identifier of the slice of its business application.

[0152] The policy adjustment parameter is used to indicate the parameter adjusted when the reservation policy of the network resource is updated, such as the trial-and-error parameter and the value range of the parameter. The trial-and-error parameter can be the relevant parameters for configuring the slice and the slice subnet, such as the wireless spectrum, the tracking area (TA) list, the UE mobility level, the delay tolerance, the maximum uplink and downlink packet size, the uplink and downlink reliability, the resource sharing level, etc. The reservation policy is used to indicate the configuration mode of the reserved network resources, such as configuring the air interface frequency band and coverage of the slice subnet (RAN), and configuring the uplink and downlink reliability and resource sharing level of the slice subnet (CN). That is to say, in the process of obtaining the reservation policy of the network resource, the obtained reservation policy can be updated, for example: when the reservation policy #1 of the network resource obtained for the first time does not meet the requirements, the reservation policy #2 can be obtained again based on the reservation policy #1, that is, the reservation policy #2 is a policy obtained based on the reservation policy #1, and in the process of obtaining the reservation policy #2, the policy adjustment parameter is adjusted. The policy adjustment parameters may be determined according to the operator's internal network management policy or according to other conditions without limitation.

[0153] The optimization stop condition is used to indicate the conditions for stopping updating the reservation strategy of network resources, such as setting the maximum number of iterations. That is to say, in the process of obtaining the reservation strategy of network resources, the obtained reservation strategy can be updated. For example, when the reservation strategy #1 of the network resources obtained for the first time does not meet the requirements, the reservation strategy #2 can be obtained again based on the reservation strategy #1. In this case, the optimization stop condition is used to indicate the conditions for stopping updating the reservation strategy, such as stopping the update after 100 updates, or the last reservation strategy obtained meets the preset requirements. It can be understood that the optimization stop condition can be flexibly set according to the actual situation without restriction. And the optimization stop condition can be determined according to the internal policy of the operator's network management, and can also be determined according to other conditions without restriction.

[0154] It can be understood that the "update" mentioned in the embodiments of the present application is only an exemplary expression, and "update" can also be replaced by any possible expression, such as "optimization" or "iteration", etc., without limitation.

[0155] The management service consumer can flexibly determine the route planning instructions, network performance requirements, evaluation precision requirements, slice identifiers, policy adjustment parameters, or optimization stop conditions according to actual conditions. It can be understood that the network performance requirements, evaluation precision requirements, policy adjustment parameters, or optimization stop conditions can be preset in the first management service providing entity. In this case, the first message may not include the network performance requirements, evaluation precision requirements, policy adjustment parameters, or optimization stop conditions.

[0156] S402: The first management service providing entity obtains a network resource reservation policy according to the first message.

[0157] The network resource reservation strategy is used to indicate the configuration method of the reserved network resources, such as configuring the air interface frequency band of the slice subnet (RAN) to be n1 and the coverage range to be TA1 (TA1 is a schematic TA identifier), and configuring the uplink and downlink reliability of the slice subnet (CN) to be 75%, and the resource sharing level to be non-shareable, etc. The network resources configured in this configuration method can guarantee the communication service quality when moving along the first route within the first time. In other words, the network resources configured in this configuration method are network resources on the first route reserved within the first time, so that when the terminal moves along the first route within the first time, the network resources can be used, thereby ensuring the communication service quality of the terminal when moving along the first route within the first time.

[0158] There are many ways to obtain the network resource reservation policy. Exemplarily, the network resource reservation policy can be obtained by the first management service provider from other entities (such as the second management service provider), or can be generated by the first management service provider itself. The following describes each case separately.

[0159] Case 1: The first management service providing entity obtains the network resource reservation policy from the second management service providing entity.

[0160] In this case, the first management service provider entity obtains the network resource reservation policy according to the first message, which may specifically include: the first management service provider entity obtains the network resource reservation policy from the second management service provider entity according to the first message. In other words, the first management service provider entity can obtain the network resource reservation policy from the second management service provider entity, without the need for the first management service provider entity to generate the network resource reservation policy according to the first message. In this way, the overhead of the first management service provider entity can be reduced.

[0161] Specifically, the first management service provider entity obtains the network resource reservation policy from the second management service provider entity based on the first message, which may specifically include: the first management service provider entity sends a fourth message to the second management service provider entity based on the first message, the fourth message is used to request to determine the network resource reservation policy according to the network performance requirements, and accordingly, the second management service provider entity receives the fourth message from the first management service provider entity; the second management service provider entity sends a fifth message to the first management service provider entity based on the fourth message, the fifth message is used to indicate the network resource reservation policy, and accordingly, the first management service provider entity receives the fifth message from the second management service entity.

[0162] The fourth message can be specifically used to indicate a request to determine a reservation strategy for network resources applicable to at least one network element according to network performance requirements (recorded as request #1), or to request to ensure the quality of communication service when moving along the first route within the first time according to network performance requirements (recorded as request #2). Which of the following is the role of the fourth message is related to the operation of the first management service provider entity. Specifically, the first management service provider entity can determine at least one network element (described below) based on the first message, and send the at least one network element to the second management service provider entity. At this time, the role of the fourth message is request #1; or, the first management service provider entity can forward the information included in the first message to the second management service provider entity. At this time, the role of the fourth message is request #2. That is to say, when the first management service provider entity performs different processing based on the first message, the corresponding fourth message is different (described below).

[0163] The fifth message may include at least one of the following: a network resource reservation policy, an identifier of the network resource reservation policy, a feature of the network resource reservation policy, or a service guarantee satisfaction degree corresponding to the network resource reservation policy.

[0164] The network resource reservation strategy is a specific configuration method for each network element, such as the configuration value of each network element attribute. The identifier of the network resource reservation strategy is a unique identifier assigned to each reservation strategy obtained by the second management service providing entity when obtaining the network resource reservation strategy. The characteristics of the network resource reservation strategy are the description of the network resource reservation strategy, such as optimal latency, optimal throughput, etc.

[0165] The service assurance satisfaction can be used to characterize the degree of match between network performance and network performance requirements. The network performance corresponds to the network performance requirements. When the network performance requirements are throughput requirements and delay requirements, the network performance is throughput and delay. The network performance is the network performance measured or estimated by the second management service providing entity. For example, if the network performance requirement is a throughput of 50 megabits per second (MB / S) and the network performance is 40MB / S, the service assurance satisfaction is 80%. The service assurance satisfaction corresponding to the network resource reservation policy can indicate the degree of match between the network performance of the network resources corresponding to the network resource reservation policy and the network performance requirements, that is, the higher the service assurance satisfaction, the better the network performance of the network resources. The network resources corresponding to the network resource reservation policy are network resources configured according to the network resource reservation policy.

[0166] It can be understood that the network resource reservation policy, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, and the service assurance satisfaction corresponding to the network resource reservation policy have a corresponding relationship. For example, when the network resource reservation policy is one policy, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, and the service assurance satisfaction corresponding to the network resource reservation policy are all parameters corresponding to the policy; when the network resource reservation policy is multiple policies, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, and the service assurance satisfaction corresponding to the network resource reservation policy all include multiple information, and the multiple information corresponds to the multiple policies respectively.

[0167] For example, the network resource reservation strategy includes three network resource reservation strategies, and the identifiers of these three network resource reservation strategies are: strategy #1, strategy #2 and strategy #3, the characteristics are: characteristic #1, characteristic #2 and characteristic #3, and the service assurance satisfaction is: satisfaction #1, satisfaction #2 and satisfaction #3. Among them, strategy #1, characteristic #1 and satisfaction #1 correspond, strategy #2, characteristic #2 and satisfaction #2 correspond, and strategy #3, characteristic #3 and satisfaction #3 correspond. These correspondences can be sent to the first management service provider entity by putting different information in the same tuple, and can also be sent to the first management service provider entity in other ways without limitation.

[0168] The following describes different situations of the fourth message.

[0169] In the first possible implementation, the fourth message is specifically used to indicate a request to determine a reservation strategy for network resources applicable to at least one network element according to network performance requirements, and the service scope of at least one network element (described below) includes a first area (described below), and the first area is the area where the first route is located.

[0170] Optionally, the fourth message includes at least one of the following: information indicating the first time, area information, or information indicating at least one network element.

[0171] The information used to indicate the first time can refer to the related introduction of the aforementioned "S401", which will not be repeated here.

[0172] The service scope of at least one network element includes the first area, that is, the service scope of at least one network element can cover the first area. At least one network element can be determined by the first management service provider according to the first route and the evaluation precision requirement. Exemplarily, the first management service provider can determine the first area according to the first route and the evaluation precision requirement; then determine the network elements that provide network services in the first area, and determine at least one network element that can cover the first area from the network elements. For example, the first management service entity determines network elements #1-network elements #6 in the first area for providing network services, and then determines network elements #2-network elements #5 that can cover the first area according to network elements #1-network elements #6, then at least one network element is network elements #2-network elements #5. The information used to indicate at least one network element can be specific information of at least one network element, such as the location and name of the network element, without limitation.

[0173] The first area is the area where the first route is located, that is, the first area can cover the first route. The first area can be determined by the first management service provider according to the first route and the evaluation precision requirement. For example, the first management service provider determines the corresponding grid according to the evaluation precision requirement, and then uses the grid to cover the first route. In other words, the first area can be composed of multiple grids.

[0174] For example, Figure 5 As shown, the grid #s is determined according to the evaluation precision requirement, the grid #s is a square grid with a length of 2m and a width of 2m, and multiple grid #s are used to cover the first route, and the area formed by the multiple grid #s is the first area; for example: Figure 6 As shown, grid #h is determined according to the evaluation precision requirement, grid #s is a square grid with a length of 1m and a width of 1m, and multiple grids #h are used to cover the first route, and the area formed by multiple grids #h is the first area. Among them, the size of grid #s is smaller than grid #h, that is, the evaluation precision requirement corresponding to grid #s is higher, and the evaluation precision requirement corresponding to grid #h is lower. It can be seen that the precision of the first area determined by grid #s is higher, that is, the higher the evaluation precision requirement, the higher the precision of the determined first area.

[0175] The area information is used to indicate multiple first grids constituting the first area, that is, when the first grid is used to cover the first route according to the evaluation precision requirement, multiple first grids can be obtained. The area information may include at least one of the following: the identification of each of the multiple first grids, the size of the multiple first grids, or the position of each of the multiple first grids, wherein the size of the multiple first grids corresponds to the evaluation precision requirement, and the position of each of the multiple first grids can be represented by the center point of each first grid, or represented in other ways, without limitation. It can be understood that the multiple first grids can be clearly indicated by the identification of each of the multiple first grids, the size of the multiple first grids, and the position of each of the multiple first grids. The area information can be determined by the first management service entity according to the first route and the evaluation precision requirement. For details, please refer to the relevant introduction of determining the first area as mentioned above, which will not be repeated here; it can also be obtained by the first management service entity from other places, without limitation.

[0176] After the first management service provider entity receives the first message, it can obtain information indicating the first time, area information, or information indicating at least one network element based on the first message, and send the information to the second management service provider entity via a third message, so that the second management service provider entity obtains the network resource reservation policy based on the third message.

[0177] Further, the first management service provider entity sends a fourth message to the second management service provider entity based on the first message, which may specifically include: the first management service provider entity obtains at least one of the following information based on the first message: area information, or information used to indicate at least one network element; the first management service provider entity sends the fourth message to the second management service provider entity based on the first message and at least one of the following information; accordingly, the second management service provider entity receives the fourth message from the first management service provider entity.

[0178] The first management service provider entity obtains the regional information and / or the information indicating at least one network element according to the first message. Please refer to the above-mentioned related introduction, which will not be repeated here. After the first management service provider entity obtains the regional information and / or the information indicating at least one network element, the regional information and / or the information indicating at least one network element can be sent to the second management service provider entity, so that the second management service provider entity can obtain the reservation strategy of network resources based on the information. In this way, the second management service provider entity does not need to obtain the regional information and / or the information indicating at least one network element according to the first message, thereby reducing the overhead of the second management service provider entity.

[0179] Optionally, the fourth message includes at least one of the following: network performance requirements, slice identifiers, policy optimization indications, policy adjustment parameters, or optimization stop conditions.

[0180] The policy optimization indication is used to indicate the optimization of the reservation policy of network resources. That is to say, in the process of obtaining the reservation policy of network resources, a better reservation policy of network resources is obtained by optimizing the obtained reservation policy of network resources. It can be understood that if the fourth message includes a policy optimization indication, it means that the second management service provider entity must obtain the reservation policy of network resources multiple times to obtain the current optimal reservation policy of network resources, that is, it cannot obtain the reservation policy of network resources only once. For network performance requirements, slice identifiers, policy adjustment parameters and optimization stop conditions, please refer to the relevant introduction of the aforementioned "S401" and will not be repeated here.

[0181] It can be understood that the network performance requirement, the policy optimization indication, the policy adjustment parameter, or the optimization stop condition can be preset in the second management service providing entity. In this case, the network performance requirement, the policy optimization indication, the policy adjustment parameter, or the optimization stop condition may not be included in the fourth message. In addition, the first management service providing entity can determine whether to optimize the reservation policy of network resources according to actual conditions, that is, whether to include the policy optimization indication in the fourth message.

[0182] Optionally, before the second management service provider sends a fifth message for indicating a network resource reservation policy to the first management service provider based on the fourth message, the above communication method may further include: the second management service provider constructs a network twin model based on the regional information and information for indicating at least one network element; the second management service provider obtains the network resource reservation policy through the network twin model based on the fourth message.

[0183] The specific manner in which the second management service providing entity constructs the network twin model based on the regional information and the information used to indicate at least one network element is not limited in this embodiment of the application. Among them, the regional information and the information used to indicate at least one network element are used to constrain the construction scope of the network twin model, as well as the scope of the evaluation object when performing simulation tasks based on the network twin model, and the specific manner in which the network data required to construct the network twin model is collected is not limited in this embodiment of the application.

[0184] After constructing the network twin model, the second management service provider entity can perform a service assurance satisfaction evaluation on each of the multiple first grids based on the initial network resource reservation strategy, that is, configure the initial network resource reservation strategy to the network twin model to simulate a digital network, and then measure the network performance of each first grid in the digital network, and compare the network performance with the network performance requirements to obtain the corresponding service assurance satisfaction.

[0185] For example, Figure 7As shown, the entire communication network in the first time period can be predicted by trend, and then the communication services of the terminal in multiple first grids can be simulated, and the network quality at this time can be measured, and the network quality can be compared with the network performance to obtain the service guarantee satisfaction. The service guarantee satisfaction corresponding to multiple first grids can be obtained in parallel, or in sequence, without restriction. After obtaining the network resource reservation strategy #1, the second management service provider entity can determine whether the service guarantee satisfaction corresponding to the network resource reservation strategy #1 meets the preset requirements. When the preset requirements are not met, the policy is updated based on the network resource reservation strategy #1 to obtain the network resource reservation strategy #2. The operation of the network resource reservation strategy #2 is the same as the network resource reservation strategy #1, that is, the obtained network resource reservation strategy is continuously updated until the service guarantee satisfaction corresponding to the last obtained network resource reservation strategy meets the preset requirements, or until the optimization stop condition is finally met, then the network resource reservation strategy update is stopped. The second management service provider entity can assign an identifier to each obtained network resource reservation strategy. Alternatively, after stopping the update, the second management service provider entity can determine N policies that meet the preset requirements based on the M network resource reservation policies obtained, and assign identifiers to the N policies, retain specific policy content, and supplement policy descriptions and service assurance satisfaction. M and N are both integers greater than 0. For example: the second management service provider entity obtains 100 network resource reservation policies, and determines 2 network resource reservation policies based on preset requirements (such as the service assurance satisfaction is greater than 1). At this time, the second management service provider entity assigns identifiers to the two network resource reservation policies, such as policy #11 and policy #22, retains the specific policy content of the two network resource reservation policies, supplements policy description #11 and satisfaction #11 for policy #11, and supplements policy description #22 and satisfaction #22 for policy #22.

[0186] It can be understood that the service assurance satisfaction can be at the route granularity, that is, a network resource reservation strategy corresponds to the service assurance satisfaction of a first route, that is, the degree to which the network performance indicators estimated by the network twin model on the first route meet the network performance requirements, such as the time it takes for the user to move from the starting point to the end point of the first route divided by the total time, or the delay short board during the entire journey divided by the delay requirement, the number of cells on the route that meet the assurance requirements divided by the number of all cells on the route, etc. The service assurance satisfaction can also be at the grid granularity, that is, a network resource reservation strategy corresponds to the service assurance satisfaction of multiple first grids constituting the first route. The service assurance satisfaction can be expressed in a variety of forms. Exemplarily, the service assurance satisfaction can be a percentage, for example: 80% means that the measured network performance meets 80% of the network performance requirements. Alternatively, the service assurance satisfaction may be used to indicate the degree of network performance compared to the network performance requirements, for example: the service assurance satisfaction is divided into three levels, such as high, medium, and low, the ratio of the measured network performance to the network performance requirements is greater than or equal to 1, corresponding to the high level, the ratio of the measured network performance to the network performance requirements is less than 1 and greater than or equal to 0.6, corresponding to the medium level, and the ratio of the measured network performance to the network performance requirements is less than 0.6, corresponding to the low level. Alternatively, the service assurance satisfaction may be a measured network performance indicator, such as: a delay of 20 milliseconds (ms), etc.

[0187] It can be understood that when the network resource reservation policy is updated, the parameters adjusted during the update can be determined based on the policy adjustment parameters. Furthermore, when the fourth message includes a policy optimization indication, the second management service provider entity will update the obtained network resource reservation policy to obtain a better network resource reservation policy, that is, at this time, the second management service provider entity will not obtain the network resource reservation policy only once.

[0188] It can also be understood that when a slice network is specified, such as when a slice identifier is included in the fourth message, the constructed network twin model can be used to predict the entire communication network in the first time period in the slice network corresponding to the slice identifier, and obtain the network resource reservation strategy based on the slice network. For details, please refer to the above-mentioned relevant introduction, which will not be repeated here.

[0189] In a second possible implementation, the fourth message is specifically used to request that the quality of communication service when moving along the first route within the first time be guaranteed according to network performance requirements.

[0190] Optionally, the fourth message includes at least one of the following: information indicating the first time, or information indicating the first route. The information indicating the first time and the information indicating the first route can refer to the relevant introduction of the aforementioned "S401", which will not be repeated here. It can be understood that in this case, the first management service provider entity does not process the information indicating the first route, but forwards the information to the second management service provider entity through the fourth message. In this way, the overhead of the first management service provider entity can be reduced.

[0191] Optionally, the fourth message includes at least one of the following: network performance requirements, slice identifiers, policy optimization indications, policy adjustment parameters, and optimization stop conditions. For details, please refer to the above-mentioned related introduction and will not be repeated here.

[0192] Optionally, before the second management service provider entity sends the fifth message to the first management service provider entity based on the fourth message, the above communication method may also include: the second management service provider entity constructs a network twin model based on the information used to indicate the first route; the second management service provider entity obtains the network resource reservation strategy through the network twin model based on the fourth message.

[0193] Specifically, the second management service provider entity may obtain regional information and at least one network element based on the information used to indicate the first route and the evaluation precision requirement. The specific operation is similar to the operation of the first management service provider entity obtaining regional information and at least one network element based on the information used to indicate the first route and the evaluation precision requirement. Please refer to the aforementioned related introduction and will not be repeated here. After obtaining the regional information and at least one network element, a network twin model may be constructed based on the regional information and at least one network element. The second management service provider entity obtains the network resource reservation strategy through the network twin model. Please refer to the aforementioned related introduction and will not be repeated here.

[0194] Case 2: The first management service providing entity generates a network resource reservation policy.

[0195] In this case, the first management service provider entity obtains the network resource reservation policy according to the first message, which may specifically include: the first management service provider entity generates the network resource reservation policy according to the first message. That is, the first management service provider entity can generate the network resource reservation policy by itself according to the first message, without obtaining the network resource reservation policy from other entities.

[0196] Specifically, the first management service provider entity generates a network resource reservation policy based on the first message, which may specifically include: the first management service provider entity obtains regional information and at least one network element based on the information used to indicate the first route; the first management service provider entity constructs a network twin model based on the regional information and at least one network element; the first management service provider entity obtains the network resource reservation policy through the network twin model based on the first message.

[0197] It can be understood that the first management service provider entity obtains the regional information and at least one network element based on the information indicating the first route, and the aforementioned related introduction can be referred to, which will not be repeated here. In addition, the first management service provider entity constructs a network twin model based on the regional information and at least one network element, and obtains the network resource reservation strategy through the network twin model, which is similar to the operation of the aforementioned second management service provider entity, and the aforementioned related introduction can be referred to, which will not be repeated here.

[0198] S403: The first management service providing entity triggers configuration of network resources according to a network resource reservation policy.

[0199] The network resource reservation policy can be one policy or multiple policies, which is specifically related to the reservation policy of the network resources obtained by the second management service provider entity. When the network resource reservation policy is one policy, the first management service provider entity can trigger the configuration of network resources according to the policy; when the network resource reservation policy includes multiple policies, the first management service provider entity can trigger the configuration of network resources according to a policy selected from the multiple policies, and the policy can be selected by the first management service provider entity or by the management service consumer without limitation. The specific method of triggering the configuration of network resources according to the network resource reservation configuration is not limited in the embodiments of the present application.

[0200] Optionally, after the first management service provider entity obtains the network resource reservation policy, the above communication method may also include: the first management service provider entity sends a second message for indicating the network resource reservation policy to the management service consumer according to the network resource reservation policy; accordingly, the management service consumer receives the second message from the first management service provider entity.

[0201] The second message may include at least one of the following: a network resource reservation policy, an identifier of the network resource reservation policy, a characteristic of the network resource reservation policy, or a service guarantee satisfaction level corresponding to the network resource reservation policy. For each information, please refer to the relevant introduction at the aforementioned "S402" and will not be repeated here.

[0202] It is understandable that the network resource reservation policy may not be included in the second message. That is, for the management service consumer, it does not need to know the specific content of the network resource reservation policy, but can know that the network resource reservation policy has been generated, as well as the characteristics and satisfaction of the network resource reservation policy. In this way, communication overhead can be reduced.

[0203] In addition, when the network resource reservation policy is a policy, the first management service provider entity triggers the configuration of network resources according to the network resource policy (S403) and the first management service provider entity sends the second message to the management service consumer according to the network resource reservation policy. They can be performed simultaneously or in a sequence, such as the first management service provider entity first triggers the configuration of network resources and then sends the second message to the management service consumer, or the first management service provider entity first sends the second message to the management service consumer and then triggers the configuration of network resources, without any restriction.

[0204] When the network resource reservation policy includes multiple policies, and the management service consumer selects an application policy from the multiple policies, after receiving the second message, the management service consumer can select a policy from the multiple policies and send the policy to the first management service provider, so that the first management service provider triggers the configuration of network resources according to the policy. That is, in this case, the first management service provider triggers the configuration of network resources according to the network resource reservation policy, which can specifically include: the management service consumer sends a third message indicating the application policy to the first management service provider according to the second message, and the application policy is a policy selected from the network resource reservation policy. Correspondingly, the first management service provider receives the third message indicating the application policy from the management service consumer; the first management service provider triggers the configuration of network resources according to the application policy. That is, at this time, the first management service provider needs to first send the second message indicating the network resource reservation policy to the management service consumer, and after the management service consumer determines the application policy based on the second message and sends the application policy to the first management service provider through the third message, the first management service provider triggers the configuration of network resources based on the application policy.

[0205] It can also be understood that when the network resource reservation policy includes multiple policies and the first management service consumer can select an application policy from the multiple policies, the first management service consumer can send relevant information of the selected application policy to the management service consumer.

[0206] In summary, in the embodiment of the present application, after receiving the first message from the management service consumer, the first management service providing entity can reserve network resources corresponding to the first route within the first time according to the first message, so that the terminal can use the network resources when moving along the first route within the first time. In this way, the communication service quality of the terminal when moving along the first route within the first time can be guaranteed.

[0218] S805: The second management service providing entity sends a fifth message to the first management service providing entity. Correspondingly, the first management service providing entity receives the fifth message from the second management service providing entity.

[0219] The fifth message is used to indicate the network resource reservation strategy, and the fifth message includes: the network resource reservation strategy, the identifier of the network resource reservation strategy, the characteristics of the network resource reservation strategy, and the service guarantee satisfaction corresponding to the network resource reservation strategy. For details, please refer to the relevant introduction of the aforementioned "S402", which will not be repeated here.

[0220] S806: The first management service providing entity sends a second message to the management service consumer. Correspondingly, the management service consumer receives the second message from the first management service providing entity.

[0221] The second message is used to indicate the network resource reservation strategy, and the second message includes: an identifier of the network resource reservation strategy, characteristics of the network resource reservation strategy, and service guarantee satisfaction corresponding to the network resource reservation strategy. For details, please refer to the related introduction of the aforementioned "S403", which will not be repeated here.

[0222] S807: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0223] When the network resource reservation policy is one policy, the first management service providing entity may trigger the configuration of network resources according to the policy; when the network resource reservation policy includes multiple policies, the first management service providing entity may receive a third message ( Figure 8 In S806'), the application policy is a policy selected from the network resource reservation policy; and according to the application policy, the configuration of network resources is triggered.

[0224] It can be understood that the specific implementation of S801-S807 can refer to the relevant introduction of the aforementioned S401-S403, which will not be repeated here.

[0225] Scenario 2:

[0226] Fig. 9 Schematic diagram of the communication method provided in the embodiment of the present application Figure 2 . The communication method is applicable to the above-mentioned communication system, and mainly involves a management service consumer, a first management service provider entity, and a second management service provider entity. In scenario 1, the management service consumer can request the first management service provider entity to guarantee the quality of communication services when moving along the first route within the first time according to network performance requirements, and indicate the network slice to be used. The first management service provider entity can obtain the network resource reservation policy from the second management service provider entity, and trigger the configuration of network resources based on the network resource reservation policy.

[0227] like Fig. 9 As shown, the process of the communication method is as follows:

[0228] S901: A management service consumer sends a first message to a first management service provider. Correspondingly, the first management service provider receives the first message from the management service consumer.

[0249] It can be understood that the specific implementation of 1001-S1004 can refer to the relevant introduction of the aforementioned S401-S403, which will not be repeated here.

[0250] Scenario 4:

[0251] Fig.11 Schematic diagram of the communication method provided in the embodiment of the present application Figure 4. This communication method is applicable to the above-mentioned communication system, and mainly involves a management service consumer and a first management service providing entity. In scenario 3, the management service consumer can request the first management service providing entity to guarantee the quality of communication services when moving along the first route within the first time according to the network performance requirements, and indicate the network slice to be used. The first management service providing entity generates a network resource reservation policy based on the request, and triggers the configuration of network resources based on the network resource reservation policy.

[0252] like Fig.11 As shown, the process of the communication method is as follows:

[0253] S1101: A management service consumer sends a first message to a first management service provider. Correspondingly, the first management service provider receives the first message from the management service consumer.

[0254] The first message is used to request that the quality of communication service when moving along the first route within the first time be guaranteed according to network performance requirements, and the first message includes: information indicating the first time, information indicating the first route, route planning instructions, network performance requirements, evaluation precision requirements, and slice identifiers.

[0259] It can be understood that the operations of S1101-S1104 are similar to the aforementioned S1001-S1004, except that: the first message (S1101) carries a slice identifier, and the second management service provider entity obtains a network reservation policy based on the slice network corresponding to the slice identifier. S1101-S1104 can refer to the aforementioned S1001-S1004 and the aforementioned S401-S403 for related introductions, which will not be repeated here.

[0260] For example, Fig.12 Schematic diagram of the communication method provided in the embodiment of the present application Figure 6 The method may be applicable to the communication between the management service consumer and the first management service providing entity in the above communication system.

[0261] like Fig.12 As shown, the process of the communication method is as follows:

[0262] S1201: A management service consumer sends a first message to a first management service provider. Correspondingly, the first management service provider receives the first message from the management service consumer.

[0263] The first message is used to request a route from the first starting point to the first end point, and to ensure the quality of communication services when moving along the route according to network performance requirements. The network performance requirements can be referred to in the above-mentioned "S401", which will not be repeated here.

[0264] Optionally, the first message may include at least one of the following: information indicating a first time, information indicating a first starting point, or information indicating a first end point.

[0265] The first time and the information used to indicate the first time can refer to the related introduction of the aforementioned "S401", which will not be repeated here. The first starting point is the starting point where the terminal is expected to move. The first end point is the end point where the terminal is expected to move. The information used to indicate the first starting point and the information used to indicate the first end point can both be coordinate points, such as longitude and latitude coordinates. It can be understood that the terminals in the embodiments of the present application are all terminals that can be managed by the management service consumer.

[0266] The management service consumer can flexibly determine the first time, the first starting point, or the first end point according to the actual situation of the terminal, such as determining the first time according to the expected movement time of the terminal, and / or determining the first starting point and the first end point according to information such as the expected movement area of ​​the terminal, and send a first message carrying information for indicating the first starting point, information for indicating the first end point, or information for indicating the first time to the first management service provider entity, so as to ensure the quality of communication services based on such information.

[0267] It can be understood that when the first starting point, the first end point, or the first time is preset in the first management service providing entity, the first message may not include information for indicating the first starting point, information for indicating the first end point, or information for indicating the first time. In other words, if the first message does not include information for indicating the first starting point, information for indicating the first end point, or information for indicating the first time, it can be indicated that the information for indicating the first starting point, the information for indicating the first end point, or the information for indicating the first time has been preset in the first management service providing entity.

[0268] Optionally, the first message may include: route planning instructions, network performance requirements, evaluation precision requirements, slice identification, policy adjustment parameters, optimization stop conditions, passing points, passing areas, restricted areas, and route preferences.

[0269] For route planning instructions, network performance requirements, evaluation precision requirements, slice identifiers, policy adjustment parameters, and optimization stop conditions, please refer to the relevant introduction of S401 above, which will not be repeated here. It can be understood that in an embodiment of the present application, a mobile route needs to be provided, that is, the route planning instruction is used to indicate that a mobile route needs to be provided. Therefore, when the route planning instruction is used to indicate whether a mobile route needs to be provided, the first message includes a route planning instruction for indicating that a mobile route needs to be provided, and when the first management service provider receives the first message including the route planning instruction, it can be determined that a mobile route needs to be provided based on the route planning instruction. Alternatively, when the route planning instruction is used to indicate that a mobile route needs to be provided, the first message includes the route planning instruction, and when the first management service provider receives the first message, it can be determined that a mobile route needs to be provided based on the route planning instruction included in the first message. When the first management service provider determines that a mobile route needs to be provided, it can reserve network resources for the management service consumer and provide a mobile route to ensure the network quality of the terminal when it is moving.

[0270] The passing point is used to indicate the place that needs to be passed, and the passing point can be represented by longitude and latitude coordinates. In other words, the mobile strategy requested by the management service consumer needs to pass through the place.

[0271] The passing area is used to indicate the area that needs to be passed through, and the passing area can be represented by multiple coordinate points constituting the area, or by other methods that can represent the area, without limitation. That is, the mobile strategy requested by the management service consumer needs to pass through the area.

[0272] The restricted area is used to indicate a place or area that cannot be passed through. The place can be represented by longitude and latitude coordinates, the area can be represented by multiple coordinate points that constitute the area, or other methods that can represent the area are not limited. In other words, the mobile policy requested by the management service consumer cannot pass through the place or the area.

[0273] Route preference is used to represent the requirements for the moving route, such as: the route is less than 50m, or the route is a straight line, etc. It can be set according to the actual situation without restriction.

[0274] The management service consumer can flexibly determine the route planning instructions, network performance requirements, evaluation precision requirements, slice identifiers, policy adjustment parameters, optimization stop conditions, passing points, passing areas, restricted areas, and route preferences according to actual conditions. It can be understood that the network performance requirements, evaluation precision requirements, policy adjustment parameters, or optimization stop conditions, passing points, passing areas, restricted areas, and route preferences can be preset in the first management service providing entity. In this case, the first message may not include this information.

[0275] S1202: The first management service providing entity obtains a network resource reservation strategy and a first route according to the first message.

[0276] The network resource reservation strategy is used to indicate the configuration method of the reserved network resources. The network resources configured in this configuration method can ensure the communication service quality when moving along the first route within the first time. For details, please refer to the relevant introduction of the aforementioned "S402", which will not be repeated here. The first route is a route from the first starting point to the first end point, and the network resource reservation strategy is a reservation strategy for the network resources of the route.

[0277] There are many ways to obtain the network resource reservation strategy and the first route. The network resource reservation strategy and the first route can be obtained by the first management service provider from other entities (such as the second management service provider), or can be generated by the first management service provider itself. The following describes each case separately.

[0278] Case 1: The first management service providing entity obtains the network resource reservation policy and the first route from the second management service providing entity.

[0279] In this case, the first management service provider entity obtains the network resource reservation strategy and the first route according to the first message, which may specifically include: the first management service provider entity obtains the network resource reservation strategy and the first route from the second management service provider entity according to the first message. In other words, the first management service provider entity can obtain the network resource reservation strategy and the first route from the second management service provider entity, without the first management service provider entity generating the network resource reservation strategy and the first route according to the first message. In this way, the overhead of the first management service provider entity can be reduced.

[0280] Specifically, the first management service provider entity obtains the network resource reservation strategy and the first route from the second management service provider entity based on the first message, which may specifically include: the first management service provider entity sends a fourth message to the second management service provider entity based on the first message, the fourth message is used to request the provision of a route from the first starting point to the first end point, and to determine the network resource reservation strategy according to network performance requirements, and accordingly, the second management service provider entity receives the fourth message from the first management service provider entity; the second management service provider entity sends a fifth message for indicating the network resource reservation strategy and the first route to the first management service provider entity based on the fourth message, and accordingly, the first management service provider entity receives the fifth message from the second management service entity.

[0281] The fourth message can be specifically used to indicate a request to provide a route from the first starting point to the first end point, and to determine a network resource reservation strategy applicable to at least one network element (described below) according to network performance requirements (recorded as request #11), or to request to provide a route from the first starting point to the first end point, and to ensure the quality of communication service when moving along the route according to network performance requirements (recorded as request #22). Which of the following is the role of the fourth message is related to the operation of the first management service provider entity. Specifically, the first management service provider entity can determine at least one network element based on the first message, and send the at least one network element to the second management service provider entity. At this time, the role of the fourth message is request #11; or, the first management service provider entity can forward the information included in the first message to the second management service provider entity. At this time, the role of the fourth message is request #22. That is to say, when the first management service provider entity performs different processing based on the first message, the corresponding fourth message is different (described below).

[0282] The fifth message may include at least one of the following: a network resource reservation policy, an identifier of the network resource reservation policy, a characteristic of the network resource reservation policy, a first route, an identifier of the first route, a service guarantee satisfaction degree corresponding to the first route, or a characteristic of the first route.

[0283] The network resource reservation strategy, the identifier of the network resource reservation strategy, the characteristics of the network resource reservation strategy, and the service guarantee satisfaction can refer to the relevant introduction of the aforementioned "S402", which will not be repeated here.

[0284] The first route is the route from the first starting point to the first end point. There are many ways to express the first route, for example, the route can be represented by multiple coordinate points, and the route can be obtained by connecting the multiple coordinate points; another example: the route is represented by multiple grids covering the route, and the route can be obtained by connecting the multiple grids in sequence, without limitation. It can be understood that, for example Figure 5 and Figure 6 As shown, when a route is represented by multiple grids, if the fineness of the multiple grids is higher, that is, the grid size is smaller, the route can be represented more accurately; correspondingly, if the fineness of the multiple grids is lower, that is, the grid size is larger, the route based on the multiple grid areas is less accurate. It can also be understood that the first route can be one route or multiple routes.

[0285] It can be understood that in the embodiment of the present application, the first route has a corresponding relationship with the network resource reservation strategy, that is, the service assurance satisfaction corresponding to the first route can also be called the service assurance satisfaction corresponding to the network resource reservation strategy. In other words, the service assurance satisfaction corresponding to the first route is similar to the service assurance satisfaction corresponding to the network resource reservation strategy in the aforementioned "S402". Please refer to the relevant introduction of the aforementioned "S402" and will not be repeated here.

[0286] It can also be understood that the network resource reservation policy, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, the first route, the identifier of the first route, the service assurance satisfaction corresponding to the first route, and the characteristics of the first route have a corresponding relationship. For example, when the first route is one route, the network resource reservation policy, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, the first route identifier, the service assurance satisfaction corresponding to the first route, and the characteristics of the first route are all parameters of the first route; when the first route is multiple routes, the network resource reservation policy, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, the first route identifier, the service assurance satisfaction corresponding to the first route, and the characteristics of the first route all include multiple information, and the multiple information corresponds to the multiple routes respectively.

[0287] For example, the first route includes three routes, the identifiers of these three routes are route #1, route #2 and route #3, the characteristics are route characteristic #1, route characteristic #2 and route characteristic #3, and the service assurance satisfaction is satisfaction #1, satisfaction #2 and satisfaction #3; the network resource reservation strategy includes three network resource reservation strategies, the identifiers of these three network resource reservation strategies are strategy #1, strategy #2 and strategy #3, and the characteristics are strategy characteristic #1, strategy characteristic #2 and strategy characteristic #3. Among them, route #1, route characteristic #1, satisfaction #1, strategy #1 and strategy characteristic #1 correspond, route #2, route characteristic #2, satisfaction #2, strategy #2 and strategy characteristic #2 correspond, route #3, route characteristic #3, satisfaction #3, strategy #3 and strategy characteristic #3 correspond. These correspondences can be sent to the first management service provider entity by putting different information in the same tuple, and can also be sent to the first management service provider entity in other ways without limitation.

[0288] The following describes different situations of the fourth message.

[0289] In the first possible implementation, the fourth message is specifically used to indicate a request to provide a route from a first starting point to a first end point, and to determine a reservation strategy for network resources applicable to at least one network element according to network performance requirements, wherein the service scope of at least one network element (described below) includes a first area (described below), and the first area includes a first starting point and a first end point.

[0290] Optionally, the fourth message may include at least one of the following: information indicating a first starting point, information indicating a first end point, area information, information indicating at least one network element, or information indicating a first time.

[0291] The information used to indicate the first time, the area information, at least one network element, and the information used to indicate at least one network element can refer to the relevant introduction of the aforementioned "S401", which will not be repeated here. The information used to indicate the first starting point and the information used to indicate the first end point can refer to the relevant introduction of the aforementioned "S1201", which will not be repeated here.

[0292] It can be understood that in the embodiment of the present application, the first area can be the area where the route from the first starting point to the first end point is located, that is, the first area includes the first starting point and the first end point, that is, the first area can cover the first starting point and the first end point. It can be understood that the first area can be determined based on the first starting point and the first end point according to actual conditions, for example: the size of the first area can be preset, and the first area can be determined based on the size, the first starting point and the first end point; for another example: the shape of the first area can be preset, and the first area can be determined based on the shape, the first starting point and the first end point, without limitation.

[0293] After receiving the first message, the first management service provider entity can obtain information indicating the first starting point, information indicating the first end point, area information, information indicating at least one network element, and information indicating the first time based on the first message, and send the information to the second management service provider entity via a third message, so that the second management service provider entity obtains the network resource reservation strategy and the first route based on the third message.

[0294] Furthermore, the first management service provider entity sends a fourth message to the second management service provider entity based on the first message, which may specifically include: the first management service provider entity obtains at least one of the following information based on the first message: area information, or information used to indicate at least one network element; the first management service provider entity sends the fourth message to the second management service provider entity based on the first message and at least one of the following information, and accordingly, the second management service provider entity receives the fourth message from the first management service provider entity.

[0295] The first management service provider entity obtains regional information and / or information indicating at least one network element according to the first message. Please refer to the above-mentioned related introduction and will not be repeated here. After the first management service provider entity obtains the regional information and / or information indicating at least one network element, the regional information and / or information indicating at least one network element may be sent to the second management service provider entity so that the second management service provider entity can obtain the reservation strategy and the first route of network resources based on the information. In this way, the second management service provider entity does not need to obtain the regional information and / or information indicating at least one network element according to the first message, thereby reducing the overhead of the second management service provider entity.

[0296] Optionally, the fourth message includes at least one of the following: network performance requirements, slice identification, policy optimization indication, policy adjustment parameters, optimization stop conditions, passing points, restricted areas, or route preferences.

[0297] For network performance requirements, slice identification, policy optimization indication, policy adjustment parameters and optimization stop conditions, please refer to the relevant introduction of the aforementioned "S401", which will not be repeated here. For passing points, restricted areas and route preferences, please refer to the relevant introduction of the aforementioned "S1201", which will not be repeated here.

[0298] It can be understood that the network performance requirements, the policy optimization indication, the policy adjustment parameters, the optimization stop conditions, the passing points, the restricted areas, or the route preferences can be preset in the second management service providing entity. In this case, the fourth message may not include the network performance requirements, the policy optimization indication, the policy adjustment parameters, the optimization stop conditions, the passing points, the restricted areas, or the route preferences. In addition, the first management service providing entity can determine whether to optimize the reservation strategy of network resources according to actual conditions, that is, whether to include the policy optimization indication in the fourth message.

[0299] Optionally, before the second management service provider sends a fifth message for indicating a network resource reservation strategy and a first route to the first management service provider based on the fourth message, the above-mentioned communication method may further include: the second management service provider constructs a network twin model based on the regional information and the information for indicating at least one network element, and obtains the network resource reservation strategy and the first route through the network twin model based on the fourth message.

[0300] The second management service providing entity builds a network twin model based on the regional information and the information used to indicate at least one network element, and obtains the network resource reservation strategy through the network twin model. Please refer to the relevant introduction of the aforementioned "S402" and will not be repeated here.

[0301] It is understandable that Fig.13 As shown, after determining each reservation strategy of the network resources, the second management service providing entity can determine the corresponding route from the first starting point to the first end point according to the policy pre-verification result corresponding to the reservation strategy, that is, determine the corresponding route based on the service guarantee satisfaction of each first grid constituting the first area. When determining the route, the route can be determined based on multiple first grids that meet the service guarantee satisfaction requirements, so that the communication service quality of the terminal when moving along the route within the first time can be guaranteed.

[0302] It can also be understood that the second management service providing entity may assign an identifier to each route when determining a route, and supplement the route feature description and service guarantee satisfaction for the first route when determining the first route.

[0303] In the second possible implementation, the fourth message is specifically used to indicate a request to provide a route from the first starting point to the first end point, and to ensure the quality of communication service when moving along the route according to network performance requirements.

[0304] Optionally, the fourth message may include at least one of the following: information indicating the first time, information indicating the first starting point, or information indicating the first end point. For each information, please refer to the relevant introduction of the aforementioned "S1201", which will not be repeated here. It can be understood that in this case, the first management service provider entity does not process the information indicating the first time and the information indicating the first starting point, but forwards each information to the second management service provider entity through the fourth message. In this way, the overhead of the first management service provider entity can be reduced.

[0305] Optionally, the fourth message may include at least one of the following: network performance requirements, slice identification, policy optimization indication, policy adjustment parameters, optimization stop conditions, passing points, restricted areas, or route preferences. The information can be referred to the above-mentioned related introduction and will not be repeated here.

[0306] Optionally, before the second management service provider sends a fifth message for indicating the network resource reservation strategy and the first route to the first management service provider based on the fourth message, the above-mentioned communication method may also include: the second management service provider constructs a network twin model based on the information for indicating the first starting point and the information for indicating the first end point, and obtains the network resource reservation strategy and the first route through the network twin model based on the fourth message.

[0307] Specifically, the second management service provider entity may obtain regional information and at least one network element based on the information used to indicate the first time, the information used to indicate the first starting point, and the evaluation precision requirement. The specific operation is similar to the operation of the first management service provider entity obtaining regional information and at least one network element based on the information used to indicate the first time, the information used to indicate the first starting point, and the evaluation precision requirement. Please refer to the aforementioned related introduction and will not be repeated here. After obtaining the regional information and at least one network element, a network twin model may be constructed based on the regional information and at least one network element. The second management service provider entity obtains the network resource reservation strategy through the network twin model. Please refer to the aforementioned related introduction and will not be repeated here.

[0308] Case 2: The first management service providing entity generates a network resource reservation policy.

[0309] In this case, the first management service provider entity obtains the network resource reservation strategy and the first route according to the first message, which may specifically include: the first management service provider entity generates the network resource reservation strategy and the first route according to the first message. That is, the first management service provider entity can generate the network resource reservation strategy and the first route by itself according to the first message, without obtaining the network resource reservation strategy and the first route from other entities.

[0310] Specifically, the first management service provider entity generates a network resource reservation strategy and a first route based on the first message, which may specifically include: the first management service provider entity obtains regional information and at least one network element based on information used to indicate the first starting point and information used to indicate the first end point; the first management service provider entity constructs a network twin model based on the regional information and at least one network element; the first management service provider entity obtains the network resource reservation strategy and the first route through the network twin model based on the first message.

[0311] It can be understood that the first management service provider entity obtains the regional information and at least one network element based on the information indicating the first starting point and the information indicating the first end point. Please refer to the above-mentioned related introduction, which will not be repeated here. In addition, the first management service provider entity constructs a network twin model based on the regional information and at least one network element, and obtains the network resource reservation strategy and the first route through the network twin model, which is similar to the operation of the second management service provider entity. Please refer to the above-mentioned related introduction, which will not be repeated here.

[0312] S1203, the first management service providing entity sends a second message indicating the network resource reservation strategy and the first route to the management service consumer. Correspondingly, the management service consumer receives the second message indicating the network resource reservation strategy and the first route from the first management service providing entity.

[0313] The second message may include at least one of the following: a network resource reservation policy, an identifier of the network resource reservation policy, a characteristic of the network resource reservation policy, a first route, an identifier of the first route, a service guarantee satisfaction degree corresponding to the first route, or a characteristic of the first route. For each information, please refer to the relevant introduction at the aforementioned "S1202" and will not be repeated here.

[0314] It is understandable that the second message may not include the network resource reservation policy. That is, for the management service consumer, it does not need to know the specific content of the network resource reservation policy, but can know that the network resource reservation policy has been generated, as well as the characteristics and satisfaction of the network resource reservation policy.

[0315] After obtaining the network resource reservation strategy and the first route, the first management service providing entity may indicate the network resource reservation strategy and the first route to the management service consumer through a second message. It is understood that the first route may include at least one route, and the network resource reservation strategy may include at least one strategy. For details, please refer to the relevant introduction of S1202 above, which will not be repeated here.

[0316] S1204: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0317] The network resource reservation policy may be one policy or multiple policies, which are specifically related to the network resource reservation policy acquired by the second management service providing entity.

[0318] When the network resource reservation policy is a policy, the first management service provider entity can trigger the configuration of network resources according to the policy. In this case, the first management service provider entity triggers the configuration of network resources according to the network resource policy (S1204) and the first management service provider entity sends the second message to the management service consumer according to the network resource reservation policy (S1203) can be performed simultaneously, or in a sequential order, such as the first management service provider entity first triggers the configuration of network resources and then sends the second message to the management service consumer, or the first management service provider entity first sends the second message to the management service consumer and then triggers the configuration of network resources, without restriction.

[0319] When the network resource reservation policy includes multiple policies, the first management service provider can trigger the configuration of network resources according to a policy selected from the multiple policies, and the policy can be selected by the first management service provider or by the management service consumer without limitation.
