Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0003] As wireless network coverage increases, terminals can use wireless networks while on the move. However, as the terminal moves, the position 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 on the move.

[0004] Therefore, how to ensure the network quality of terminals when they are on the move is a hot topic of discussion.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus for ensuring network quality when a terminal is moving.

[0007] To achieve the above objectives, this application adopts the following technical solutions:

[0008] In a first aspect, a communication method is provided, comprising: a first management service providing entity receiving a first message from a management service consumer, and obtaining a network resource reservation policy based on the first message; the first management service providing entity triggers configuration of network resources based on the network resource reservation policy; wherein the first message is used to request that the quality of communication service when moving along a first route within a first time be guaranteed according to network performance requirements, and the network resource reservation policy is used to indicate a configuration method of reserved network resources, and the network resources configured according to the configuration method can guarantee the quality of communication service when moving along the first route within the first time.

[0009] Based on the methods of the first and second aspects, it can be seen that after receiving the first message from the management service consumer, the first management service provider can reserve network resources corresponding to the first route within the first time period based on the first message, so that the terminal can use the network resources when moving along the first route within the first time period. In this way, the communication service quality of the terminal can be guaranteed when moving along the first route within the first time period.

[0010] In one possible design, the first message includes at least one of the following: information indicating the first time, or information indicating the first route. It is understood that the management service consumer can flexibly determine the first area and the first time according to actual circumstances.

[0011] In one possible design scheme, the first message includes at least one of the following: a route planning instruction, a network performance requirement, an evaluation precision requirement, a slice identifier, a policy adjustment parameter, or an optimization stop condition. The route planning instruction is used to indicate whether a mobile route needs to be provided. The evaluation precision requirement is used to indicate the size of multiple grids constituting the area covering the route. The slice identifier is used to indicate the network slice used to reserve network resources. The policy adjustment parameter is used to indicate the parameters adjusted when the network resource reservation policy is updated. The optimization stop condition is used to indicate the conditions for stopping the update of the network resource reservation policy. It can be understood that the network performance requirements can be throughput requirements, latency requirements, etc., and can be set differently according to specific circumstances. It can also be understood that the management service consumer can flexibly determine the evaluation method, evaluation precision requirement, network performance requirement, policy adjustment parameter, or optimization stop condition according to actual conditions.

[0012] In one possible design, the method described in the first aspect further includes: the first management service provider sending, based on the network resource reservation policy, a second message to the management service consumer indicating the network resource reservation policy. That is, after obtaining the network resource reservation policy, the first management service provider may send the network resource reservation policy to the management service consumer to facilitate the management service consumer's information about the reserved network resources, and may also notify the management service consumer that the network resources have been reserved.

[0013] Optionally, the second message includes at least one of the following: an identifier of the network resource reservation policy, characteristics of the network resource reservation policy, or a service guarantee satisfaction level corresponding to the network resource reservation policy, where the service guarantee satisfaction level is used to characterize the degree to which network performance matches network performance requirements. This facilitates the management service consumer to obtain relevant information about the network resource reservation policy and to perform subsequent operations based on the relevant information about the network resource reservation policy, such as selecting a desired application policy from multiple policies included in the network resource reservation policy.

[0014] Optionally, the network resource reservation policy includes multiple policies, and the first management service provider triggers the configuration of network resources based on the network resource reservation policy, including: the first management service provider receives a third message from the management service consumer indicating an application policy, where the application policy is a policy selected from the network resource reservation policy; and the first management service provider triggers the configuration of network resources based on the application policy. That is, when the network resource reservation policy includes multiple policies, the management service consumer can determine the policy to be used from the multiple policies. In this way, the determined and used application policy can meet the requirements of the management service consumer, thereby providing better service to the management service consumer.

[0015] In one possible design, the first management service provider entity obtains the network resource reservation policy based on the first message, including: the first management service provider entity obtains the network resource reservation policy from the second management service provider entity based on the first message. It is understood that the first management service provider entity can obtain the network resource reservation policy from other entities (such as the second management service provider entity), and the first management service provider entity can also generate the network resource reservation policy. The specific method of obtaining the network resource reservation policy is related to the settings of the management system. The first management service provider entity can flexibly select the method of obtaining the network resource reservation policy based on the specific settings, without limitation.

[0016] Optionally, the first management service provider entity obtains the network resource reservation policy from the second management service provider entity based on the first message, including: 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 being used to request determination of the network resource reservation policy based on network performance requirements; and the first management service provider entity receives a fifth message from the second management service entity, the fifth message being used to indicate the network resource reservation policy. That is, the first management service provider entity can obtain the network resource reservation policy by sending a request to the second management service provider entity.

[0017] Furthermore, the fourth message specifically indicates a request to determine a network resource reservation policy applicable to at least one network element based on network performance requirements, where the service range of the at least one network element includes a first area, where the first area is the area within which the first route resides. It will be appreciated that the first management service provider can determine the at least one network element based on the information indicating the first route, and send the at least one network element to the second management service provider via the fourth message, so that the second management service provider obtains the network resource reservation policy based on the at least one network element. This eliminates the need for the second management service provider to determine the at least one network element based on the information indicating the first route, thereby reducing the second management service provider's overhead.

[0018] Furthermore, the fourth message includes at least one of the following: information indicating the first time, regional information, or information indicating at least one network element, where the regional information indicates multiple first grids constituting the first region. It is understood that the first management service provider can determine at least one network element and regional information based on the information indicating the first route, and send the at least one network element and regional information to the second management service provider via the fourth message, so that the second management service provider obtains a network resource reservation policy based on the at least one network element and regional information.

[0019] Furthermore, the regional information includes at least one of the following: identifiers of the plurality of first grids, sizes of the plurality of first grids, or locations of the plurality of first grids.

[0110] For ease of understanding, the technical terms involved in the embodiments of this application are first introduced below.

[0111] 1. Network system

[0112] Figure 1 is a schematic diagram of the network system architecture. As shown in Figure 1, the network system architecture includes: a third party, operation administration and maintenance (OAM), a radio access network (RAN) network element, and a core network (CN) network element.

[0113] The third party mentioned above can also be called a third-party management controller or a third-party management system, which can be used to manage and control the terminal. For example, the third party can be an unmanned aircraft system traffic management (UTM), an unmanned aerial vehicle (UAV) operator, or an uncrewed aerial system (UAS).

[0114] 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 device, 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 smart city, a wireless terminal in 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 an onboard module, onboard module, onboard component, onboard chip, or onboard unit built into a vehicle as one or more components or units. The terminal device may also be other devices with terminal device functions, for example, a terminal device may also be a device that functions as a terminal device in D2D communication.

[0115] The embodiments of this application do not limit the form of the terminal device. The device used to implement the functions of the terminal device can be the terminal device; it can also be a device that supports the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of a chip or include a chip and other discrete devices.

[0116] For example, when a drone uses a 3rd Generation Partnership Project (3GPP) network as its access type, the UTM (or UAV operator, or UAS) may need to use the 3GPP network to confirm network status for flight path scheduling. 5G systems can assist the UTM or UAV operator in providing alternative flight paths based on the quality of service (QoS) supported in a specific area, or reconfigure network resources to achieve the required QoS.

[0117] For example, as shown in Figure 2, Company #1 plans to use drone A to conduct video inspections of the pipeline from X to Y, while Company #2 plans to use drone B to deliver packages from X to Z. Drones A and B are registered on the 5G network and can communicate with the UTM via the 5G network. The UTM obtains information about Drone A's planned flight path, such as its starting point X, end point Z, and the required quality of experience (QoE). The UTM and the 5G system determine the QoS required for the drone's service along the flight path, such as end-to-end latency and quality of experience (QoE). Based on the available analytical information, the 5G system can ensure that the service quality along Drone A's flight path meets the requirements, reconfigure network resources to provide Drone A with the required QoS along the flight path, or reroute Drone A to achieve better service assurance. The UTM (or UAS) determines the final flight path based on the information fed back by the 5G network and notifies Drone A. Drone A receives the flight path information from the UTM (or UAS) via the 5G system and initiates the flight mission.

[0118] These OAM network elements are used to perform routine network and service analysis, forecasting, planning, and configuration, as well as daily operational activities such as testing and fault management of the network and its services. They include the network management system (NMS), the single-domain management system (EMS)-RAN, and the EMS-CN. The NMS, also known as a cross-domain management system, can manage multiple single-domain management systems. The EMS can manage single-domain network elements, such as RAN network elements and CN network elements.

[0119] The above-mentioned RAN can be a device that provides access to terminal devices. For example, the RAN device may include: a next-generation mobile communication system, such as a 6G access network device, 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 this application, and this 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 (TRP or transmission point, TP) or a transmission measurement function (TMF), such as a baseband unit (building base band unit, BBU), or a centralized unit (CU) or a distributed unit (DU), an RSU with base station function, or a wired access gateway, or a 5G core network. Alternatively, RAN devices 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 known as small stations), relay stations, access points, wearable devices, vehicle-mounted devices, and the like.

[0120] The CN is mainly responsible for maintaining the subscription data of the mobile network and providing terminal devices with functions such as session management, mobility management, policy management, and security authentication. The 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).

[0121] As wireless network coverage increases, terminals can use wireless networks while on the move. However, as the terminal moves, the position 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 on the move.

[0122] Therefore, how to ensure the network quality of terminals when they are on the move is a hot topic of discussion.

[0123] In response to the above technical problems, the embodiments of the present application propose the following technical solutions to ensure network quality when the terminal is moving.

[0124] The technical solution in this application will be described below with reference to the accompanying drawings.

[0125] 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. They can also be applied to wireless fidelity (WiFi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, and Internet of Vehicles communication systems.

[0126] This application will present various aspects, embodiments, or features in the context of systems 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. Furthermore, combinations of these aspects may also be used.

[0127] Additionally, in the embodiments of this application, words such as "exemplary" and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of the word "exemplary" is intended to present concepts in a concrete manner.

[0128] 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 they intend to express 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 they intend to express are matched. In addition, the " / " mentioned in this application can be used to express an "or" relationship.

[0129] 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. Ordinary technicians in this field will know that with the evolution of 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.

[0130] To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail using the communication system shown in Figure 3 as an example. For example, Figure 3 is a schematic diagram of the architecture of a communication system applicable to the communication method provided in the embodiments of the present application.

[0131] The communication system includes a management service consumer and a first management service provider. The management service consumer is the caller of the management service and can request the management service provided by the management service provider. The first management service provider is responsible for providing the management service and receiving requests from the management service consumer. The communication system can be applied to the aforementioned management system architecture. In this case, the management service consumer can be a third-party management system, and the first management service provider can be deployed on the EMS-RAN and EMS-CN, or on the NMS.

[0132] Optionally, the communication system may also include a second management service provider that can provide management services. For example, this second management service provider can simulate the region by establishing a network twin model, and then rehearse management strategies on the network twin model to estimate the service assurance satisfaction of the region under different management strategies. The simulation objects may include the regional environment, such as block structure, weather, and buildings, the regional network, and the communication equipment that provides the network for the region. In this case, the management service consumer can be a third-party management system, and the second management service provider can be deployed on the NMS, EMS-RAN, and EMS-CN.

[0133] It can be understood that, as shown in FIG3 , when the communication system includes a management service consumer and a first management service providing entity, the first management service providing entity can be the management service providing entity in FIG3 . When the communication system includes a management service consumer, a first management service providing entity, and a second management service providing entity, the management service consumer and the first management service providing entity can correspond to the management service consumer and the management service providing entity in FIG3 , respectively, and the first management service providing entity and the second management service providing entity can also correspond to the management service consumer and the management service providing entity in FIG3 , respectively, that is, the first management service providing entity is the management service consumer of the second management service providing entity.

[0134] It is also understood that the "management service consumer" mentioned in the embodiments of the present application is merely 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 embodiments of the present application is merely 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.

[0135] In a communication system, a management service consumer may send a first message to a first management service provider, requesting network performance requirements to guarantee communication service quality when the terminal moves along a first route within a first time period. This allows the first management service provider to trigger configuration of a network resource reservation policy and configure network resources so that the terminal can use the network resources when moving along the first route within the first time period. In this way, network quality can be guaranteed when the terminal moves.

[0136] It can be understood that FIG3 is a simplified schematic diagram for ease of understanding, and the communication system may also include other network devices and / or other terminal devices, which are not shown in FIG3 .

[0137] For ease of understanding, the communication method provided in the embodiment of the present application will be described in detail below with reference to FIG4 .

[0138] For example, Figure 4 is a flow chart of a communication method provided by an embodiment of the present application. This method can be applied to the communication between the management service consumer and the first management service providing entity in the above communication system.

[0139] As shown in Figure 4, the process of the communication method is as follows:

[0140] 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.

[0141] The first message is used to request that the communication service quality be guaranteed according to the network performance requirement when moving along the first route within the first time.

[0142] 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. It can be the time when the terminal is expected to move, or it can include the time when the terminal is expected to move. For example: if the terminal is expected to move between 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 the management service consumer.

[0143] Optionally, the first message may include at least one of the following: information indicating the first time, or information indicating the first route.

[0144] The information used to indicate the first time may include the start time and the end time. For example, if the time for performing 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. It may also include the start time and the evaluation time period. Continuing with this 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).

[0145] The information indicating the first route may include multiple coordinate points, i.e., the first route is composed of multiple coordinate points, such as by sequentially connecting the multiple coordinate points to obtain the first route. The information may also include bit values ​​corresponding to routes agreed upon by the management service consumer and the first management service provider. For example, the first management service provider pre-sets routes #1, #2, #3, and #4, with routes #1 through #4 corresponding to bits 00, 01, 10, and 11, respectively. If the first route is route #1, the information indicating the first route is 00. The information indicating the first route may also be represented in other ways, without limitation.

[0146] The management service consumer can flexibly determine the first time and / or the first area based on 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 pre-set 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 pre-set in the first management service provider entity.

[0147] 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 stopping conditions.

[0148] Route planning instructions can be used to indicate whether a movement route is required. That is, when a movement route is required, the route planning instructions can be used to indicate that a movement route is required; conversely, the route planning instructions can be used to indicate that a movement route is not required. Route planning instructions can also be used to indicate that a movement route is required. That is, when a route planning instruction is included in a message, it indicates that a movement route is required; when a route planning instruction is not included in the message, it indicates that a movement route is not required.

[0149] 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.

[0150] It can also be understood that in an embodiment of the present application, the route planning indication is used to indicate that a mobile route does not need to be provided. Therefore, when the route planning indication is used to indicate whether a mobile route needs to be provided, the first message includes a route planning indication for indicating that a mobile route does not need to be provided, and when the first management service providing entity receives the first message including the route planning indication, it can be determined that a mobile route does not need to be provided based on the route planning indication. Alternatively, when the route planning indication is used to indicate that a mobile route needs to be provided, the first message does not include the route planning indication, and when the first management service providing entity receives the first message, it can be determined that a mobile route does not need to be provided based on the fact that the route planning indication is not included in the first message. When the first management service providing entity determines that a mobile route does not need to be provided, it can reserve network resources for the management service consumer to ensure the network quality of the terminal when it is moving.

[0151] For network performance requirements, please refer to the aforementioned introduction and will not be repeated here.

[0152] 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 flat area route, 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 (m2). 2 When the route is a three-dimensional area (three-dimensional space) route, 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.

[0153] 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.

[0154] The policy adjustment parameter is used to indicate the parameters adjusted when the network resource reservation policy is updated, such as trial-and-error parameters and the value range of the parameter. The trial-and-error parameters can be parameters related to configuring slices and slice subnets, such as wireless spectrum, tracking area (TA) list, UE mobility level, delay tolerance, uplink and downlink maximum packet size, uplink and downlink reliability, resource sharing level, etc. The reservation policy is used to indicate the configuration method 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, in the process of obtaining the network resource reservation policy, the obtained reservation policy can be updated. For example, if the network resource reservation policy #1 obtained for the first time does not meet the requirements, reservation policy #2 can be obtained again based on reservation policy #1. That is, reservation policy #2 is the policy obtained based on reservation policy #1, and the policy adjustment parameter is adjusted during the process of obtaining reservation policy #2. The policy adjustment parameters may be determined according to the operator's internal network management policy or other conditions without limitation.

[0155] The optimization stop condition is used to indicate the conditions for stopping the update of the reservation policy of the network resource, such as setting the maximum number of iterations. 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. In this case, the optimization stop condition is used to indicate the conditions for stopping the update of the reservation policy, such as stopping the update after 100 updates, or the reservation policy obtained last meets the preset requirements. It can be understood that the optimization stop condition can be flexibly set according to the actual situation without any restrictions. The optimization stop condition can be determined according to the internal policy of the operator's network management, or it can be determined according to other conditions without any restrictions.

[0156] 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.

[0157] The management service consumer can flexibly determine route planning instructions, network performance requirements, evaluation precision requirements, slice identifiers, policy adjustment parameters, or optimization stopping conditions based on actual conditions. It is understood that the network performance requirements, evaluation precision requirements, policy adjustment parameters, or optimization stopping conditions can be pre-set 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 stopping conditions.

[0158] S402: The first management service providing entity obtains a network resource reservation policy according to the first message.

[0159] The network resource reservation policy 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.

[0160] There are multiple ways to obtain the network resource reservation policy. For example, 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.

[0161] Case 1: The first management service providing entity obtains the network resource reservation policy from the second management service providing entity.

[0162] In this case, the first management service provider obtaining the network resource reservation policy based on the first message may specifically include: the first management service provider obtaining the network resource reservation policy from the second management service provider based on the first message. In other words, the first management service provider can obtain the network resource reservation policy from the second management service provider, eliminating the need for the first management service provider to generate the network resource reservation policy based on the first message. This reduces the overhead of the first management service provider.

[0163] 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, and the fourth message is used to request to determine the network resource reservation policy according to the network performance requirements. 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, and the fifth message is used to indicate the network resource reservation policy. Accordingly, the first management service provider entity receives the fifth message from the second management service entity.

[0164] 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 a request to guarantee 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. In this case, 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. In this case, 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).

[0165] 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, or a service guarantee satisfaction degree corresponding to the network resource reservation policy.

[0166] A network resource reservation policy is a specific configuration method for each network element, such as the configuration value of each network element attribute. A network resource reservation policy identifier is a unique identifier assigned by the second management service provider to each obtained network resource reservation policy when obtaining the network resource reservation policy. A network resource reservation policy characteristic is a description of the network resource reservation policy, such as optimal latency or optimal throughput.

[0167] The service assurance satisfaction can be used to characterize the degree of match between network performance and network performance requirements. Network performance corresponds to 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.

[0168] 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 these multiple information correspond to the multiple policies respectively.

[0169] For example, the network resource reservation policy includes three network resource reservation policies. The identifiers of these three network resource reservation policies are: Policy #1, Policy #2, and Policy #3, their characteristics are: Characteristics #1, Characteristics #2, and Characteristics #3, and their service assurance satisfaction levels are: Satisfaction #1, Satisfaction #2, and Satisfaction #3. Among them, Policy #1, Characteristics #1, and Satisfaction #1 correspond to each other; Policy #2, Characteristics #2, and Satisfaction #2 correspond to each other; and Policy #3, Characteristics #3, and Satisfaction #3 correspond to each other. These correspondences can be sent to the first management service provider entity by placing different information in the same tuple, or by other means, without limitation.

[0170] Different situations of the fourth message are described below.

[0171] 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.

[0172] 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.

[0173] The information used to indicate the first time can refer to the relevant introduction of the aforementioned "S401" and will not be repeated here.

[0174] 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. The at least one network element can be determined by the first management service provider entity according to the first route and the evaluation precision requirement. For example, the first management service provider entity can determine the first area according to the first route and the evaluation precision requirement; then determine the network elements providing 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 to #6 in the first area for providing network services, and then determines network elements #2 to #5 that can cover the first area based on network elements #1 to #6, then at least one network element is network elements #2 to #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, etc., without limitation.

[0175] 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 based on the first route and the evaluation precision requirement. For example, the first management service provider determines a corresponding grid based on the evaluation precision requirement and then uses this grid to cover the first route. In other words, the first area can be composed of multiple grids.

[0176] For example, as shown in Figure 5, based on the evaluation precision requirement, grid #s is determined. Grid #s is a square grid with a length of 2m and a width of 2m. Multiple grids #s are used to cover the first route, and the area formed by multiple grids #s is the first area. For another example, as shown in Figure 6, based on the evaluation precision requirement, grid #h is determined. Grid #s is a square grid with a length of 1m and a width of 1m. Multiple grids #h are used to cover the first route, and the area formed by multiple grids #h is the first area. Grid #s is smaller than grid #h, meaning that grid #s corresponds to a higher evaluation precision requirement, while grid #h corresponds to a lower evaluation precision requirement. It can be seen that the first area determined by grid #s has higher precision; that is, the higher the evaluation precision requirement, the higher the precision of the determined first area.

[0177] The region information is used to indicate the multiple first grids that constitute the first region. That is, when the first grids are used to cover the first route according to the evaluation precision requirement, multiple first grids can be obtained. This region information may include at least one of the following: identifiers of each of the multiple first grids, sizes of the multiple first grids, or positions of each of the multiple first grids. The sizes of the multiple first grids correspond to the evaluation precision requirement, and the positions of the multiple first grids can be represented by their respective center points or by other means, without limitation. It will be understood that the identifiers, sizes, and positions of the multiple first grids can clearly indicate the multiple first grids. The region information can be determined by the first management service entity based on the first route and the evaluation precision requirement. For details, please refer to the aforementioned description of determining the first region and will not be repeated here. The region information can also be obtained by the first management service entity from other sources, without limitation.

[0178] 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 this information to the second management service provider entity through a third message, so that the second management service provider entity obtains the network resource reservation policy based on the third message.

[0179] 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; accordingly, the second management service provider entity receives the fourth message from the first management service provider entity.

[0180] The first management service provider entity obtains regional information and / or information indicating at least one network element based on the first message. For details, please refer to the aforementioned 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, it can send the regional information and / or information indicating at least one network element to the second management service provider entity, so that the second management service provider entity can obtain a network resource reservation policy based on the information. In this way, the second management service provider entity does not need to obtain regional information and / or information indicating at least one network element based on the first message, thereby reducing the overhead of the second management service provider entity.

[0181] 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.

[0182] 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 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 currently 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.

[0183] It is understood that the network performance requirements, policy optimization instructions, policy adjustment parameters, or optimization stopping conditions may be pre-set in the second management service providing entity. In this case, the fourth message may not include the network performance requirements, the policy optimization instructions, the policy adjustment parameters, or the optimization stopping conditions. In addition, the first management service providing entity may determine whether to optimize the network resource reservation policy based on actual circumstances, that is, whether to include the policy optimization instruction in the fourth message.

[0184] Optionally, before the second management service provider sends a fifth message for indicating the network resource reservation policy 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 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.

[0185] The specific manner in which the second management service providing entity constructs the network twin model based on the regional information and the information for indicating at least one network element is not limited in this embodiment of the application. Among them, the regional information and the information for indicating 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.

[0186] 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.

[0187] For example, as shown in Figure 7, a trend forecast can be performed for the entire communication network during a first time period. The communication services of a terminal within multiple first grids can then be simulated, and the network quality at that time can be measured. This network quality can then be compared with network performance to obtain a service assurance satisfaction degree. The service assurance satisfaction degrees corresponding to the multiple first grids can be obtained in parallel or sequentially, without limitation. After obtaining network resource reservation policy #1, the second management service provider can determine whether the service assurance satisfaction degree corresponding to network resource reservation policy #1 meets preset requirements. If it does not meet the preset requirements, the second management service provider can perform a policy update based on network resource reservation policy #1 to obtain network resource reservation policy #2. The same operations are performed on network resource reservation policy #2 as for network resource reservation policy #1, i.e., the obtained network resource reservation policies are continuously updated until the service assurance satisfaction degree corresponding to the last obtained network resource reservation policy meets the preset requirements, or until the optimization stop condition is finally met, at which point the network resource reservation policy update is stopped. The second management service provider can assign an identifier to each obtained network resource reservation policy. 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 these N policies, retain specific policy content, 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 the preset requirements (such as service assurance satisfaction is greater than 1). At this time, the second management service provider entity assigns identifiers to these 2 network resource reservation policies, such as policy #11 and policy #22, retains the specific policy content of these 2 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.

[0188] It can be understood that the service assurance satisfaction can be at the route granularity, that is, one 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 shortcoming 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, one network resource reservation strategy corresponds to the service assurance satisfaction of multiple first grids that constitute the first route. The service assurance satisfaction can be expressed in various 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 level may be used to indicate the degree to which network performance compares to network performance requirements. For example, service assurance satisfaction is divided into three levels, such as high, medium, and low. A ratio of measured network performance to network performance requirements greater than or equal to 1 corresponds to a high level, a ratio of measured network performance to network performance requirements less than 1 and greater than or equal to 0.6 corresponds to a medium level, and a ratio of measured network performance to network performance requirements less than 0.6 corresponds to a low level. Alternatively, the service assurance satisfaction level may be a measured network performance indicator, such as a latency of 20 milliseconds (ms).

[0189] It is understood that when updating the network resource reservation policy, 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 more optimized network resource reservation policy. In other words, the second management service provider entity will not obtain the network resource reservation policy only once.

[0190] 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 the network resource reservation strategy can be obtained based on the slice network. For details, please refer to the above-mentioned relevant introduction and will not be repeated here.

[0191] In a second possible implementation, the fourth message is specifically used to request that the communication service quality when moving along the first route within the first time be guaranteed according to network performance requirements.

[0192] 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 be found in the description of "S401" above and will not be repeated here. It will be appreciated that in this case, the first management service provider does not process the information indicating the first route, but instead forwards it to the second management service provider via the fourth message. This reduces the overhead of the first management service provider.

[0193] Optionally, the fourth message includes at least one of the following: network performance requirements, slice identifier, policy optimization indication, policy adjustment parameters, and optimization stop conditions. For details, please refer to the above-mentioned related introduction and will not be repeated here.

[0194] 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.

[0195] Specifically, the second management service providing entity can 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 providing entity to obtain 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 can be constructed based on the regional information and at least one network element. The second management service providing 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.

[0196] Case 2: The first management service providing entity generates a network resource reservation policy.

[0197] In this case, the first management service providing entity obtaining the network resource reservation policy based on the first message may specifically include: the first management service providing entity generating the network resource reservation policy based on the first message. In other words, the first management service providing entity may generate the network resource reservation policy based on the first message without obtaining the network resource reservation policy from another entity.

[0198] Specifically, the first management service provider entity generates a network resource reservation strategy 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 strategy through the network twin model based on the first message.

[0199] It is understood that the first management service provider entity obtains regional information and at least one network element based on the information indicating the first route. Please refer to the aforementioned related introduction and 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 a network resource reservation policy through the network twin model. This is similar to the operation of the second management service provider entity. Please refer to the aforementioned related introduction and will not be repeated here.

[0200] S403: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0201] 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. 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.

[0202] Optionally, after the first management service providing entity obtains the network resource reservation policy, the above-mentioned communication method may also include: the first management service providing 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 providing entity.

[0203] The second message may include at least one of the following: network resource reservation policy, an identifier of the network resource reservation policy, characteristics of the network resource reservation policy, or service guarantee satisfaction 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.

[0204] It is understood that the second message may not include the network resource reservation policy. That is, the management service consumer does not need to know the specific content of the network resource reservation policy, but only needs to know that the network resource reservation policy has been generated, as well as information such as the characteristics and satisfaction of the network resource reservation policy. This can reduce communication overhead.

[0205] In addition, when the network resource reservation policy is a policy, the first management service provider entity triggers the configuration of network resources (S403) according to the network resource policy 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 carried out simultaneously or in a certain 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 any restrictions.

[0206] 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 may 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 based on the policy. That is, in this case, the first management service provider triggering the configuration of network resources based on the network resource reservation policy may specifically include: the management service consumer sending a third message to the first management service provider indicating the application policy based on the second message, where the application policy is the policy selected from the network resource reservation policy; and the first management service provider receiving the third message from the management service consumer indicating the application policy; and the first management service provider triggering the configuration of network resources based on the application policy. That is, in this case, the first management service provider needs to first send the second message to the management service consumer indicating the network resource reservation policy. 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 via the third message, the first management service provider triggers the configuration of network resources based on the application policy.

[0207] 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.

[0208] In summary, in this embodiment of the present application, after receiving the first message from the management service consumer, the first management service provider can reserve network resources corresponding to the first route within the first time period based on the first message, so that the terminal can use the network resources when moving along the first route within the first time period. In this way, the communication service quality of the terminal can be guaranteed when moving along the first route within the first time period.

[0209] Scenario 1:

[0210] Figure 8 is a second flow chart of the communication method provided in an embodiment of the present application. This communication method is applicable to the above-mentioned communication system and primarily involves a management service consumer, a first management service provider, and a second management service provider. In scenario 1, the management service consumer may request the first management service provider to guarantee the quality of communication service when moving along a first route within a first time period in accordance with network performance requirements. The first management service provider may obtain a network resource reservation policy from the second management service provider and, based on the network resource reservation policy, trigger the configuration of network resources.

[0211] As shown in Figure 8, the process of the communication method is as follows:

The fourth message includes: information indicating the first time, regional information, information indicating at least one network element, network performance requirements, a policy optimization instruction, policy adjustment parameters, and optimization stop conditions. For details, please refer to the aforementioned description of "S402" and will not be repeated here.

[0218] S804: The second management service providing entity obtains a network reservation policy according to the fourth message.

[0219] Specifically, the second management service providing entity constructs a network twin model based on the area information and the information used to indicate at least one network element; and obtains the network resource reservation strategy through the network twin model based on the fourth message.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] The second message is used to indicate the network resource reservation strategy, and the second message includes: 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 "S403", which will not be repeated here.

[0224] S807: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0225] When the network resource reservation policy is a single policy, the first management service providing entity may trigger the configuration of network resources based on the policy; when the network resource reservation policy includes multiple policies, the first management service providing entity may receive a third message (S806' in FIG8 ) from the management service consumer indicating an application policy, where the application policy is a policy selected from the network resource reservation policy; and trigger the configuration of network resources based on the application policy.

[0226] 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.

[0227] Scenario 2:

[0228] Figure 9 is a flow chart of the communication method provided in an embodiment of the present application. This communication method is applicable to the above-mentioned communication system and mainly involves a management service consumer, a first management service provider, and a second management service provider. In scenario 1, the management service consumer can request the first management service provider to ensure the quality of communication service when moving along the first route within a first time according to network performance requirements, and indicate the network slice to be used. The first management service provider can obtain the network resource reservation policy from the second management service provider and trigger the configuration of network resources based on the network resource reservation policy.

[0229] As shown in Figure 9, the process of the communication method is as follows:

[0230] 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.

[0231] 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 the network performance requirements, and the first message includes: information for indicating the first time, information for indicating the first route, route planning instructions, network performance requirements, evaluation precision requirements, and slice identification. For details, please refer to the relevant introduction of the aforementioned "S401" and will not be repeated here.

[0232] S902: The first management service providing entity obtains area information and at least one network element according to the first message.

[0233] S903: The first management service providing entity sends a fourth message to the second management service providing entity. Correspondingly, the second management service providing entity receives the fourth message from the first management service providing entity.

[0234] The fourth message is used to request that a network resource reservation policy be determined according to network performance requirements. In Scenario 2, the fourth message is specifically used to indicate a request to determine a network resource reservation policy applicable to at least one network element according to network performance requirements. The fourth message includes: information indicating the first time, regional information, information indicating at least one network element, network performance requirements, a policy optimization indication, policy adjustment parameters, optimization stop conditions, and a slice identifier. For details, please refer to the relevant introduction of the aforementioned "S402" and will not be repeated here.

[0235] S904: The second management service providing entity obtains a network reservation policy according to the fourth message.

[0236] S905: 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.

[0237] S906: 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.

[0238] S907: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0239] When the network resource reservation policy is a single policy, the first management service providing entity may trigger the configuration of network resources based on the policy; when the network resource reservation policy includes multiple policies, the first management service providing entity may receive a third message (S906' in FIG9 ) from the management service consumer indicating an application policy, where the application policy is a policy selected from the network resource reservation policy; and trigger the configuration of network resources based on the application policy.

[0240] It can be understood that the operations of S901-S907 are similar to those of the aforementioned S801-S807, except that the first message (S901) and the fourth message (S903) carry 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. S901-S907 can refer to the relevant introduction of the aforementioned S801-S807 and the aforementioned S401-S403, and will not be repeated here.

[0241] Scenario 3:

[0242] Figure 10 is a fourth flow diagram of a communication method provided in an embodiment of the present application. This communication method is applicable to the aforementioned communication system and primarily involves a management service consumer and a first management service provider. In scenario 3, the management service consumer may request the first management service provider to guarantee the quality of communication service while traveling along a first route within a first timeframe, in accordance with network performance requirements. Based on this request, the first management service provider generates a network resource reservation policy and, based on this network resource reservation policy, triggers the configuration of network resources.

[0243] As shown in Figure 10, the process of the communication method is as follows:

[0244] S1001: 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.

[0245] 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 for indicating the first time, information for indicating the first route, route planning instructions, network performance requirements, and evaluation precision requirements. For details, please refer to the relevant introduction of the aforementioned "S401" and will not be repeated here.

[0246] S1002: The first management service providing entity generates a network resource reservation policy according to the first message.

[0247] S1003: 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.

[0248] The second message is used to indicate the network resource reservation strategy, and the second message includes: 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 "S403", which will not be repeated here.

[0249] S1004: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0250] When the network resource reservation policy is a single policy, the first management service providing entity may trigger the configuration of network resources based on the policy; when the network resource reservation policy includes multiple policies, the first management service providing entity may receive a third message (S1003' in FIG10 ) from the management service consumer indicating an application policy, where the application policy is a policy selected from the network resource reservation policy; and trigger the configuration of network resources based on the application policy.

[0251] 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.

[0252] Scenario 4:

[0253] Figure 11 is a flowchart diagram of the communication method provided in an embodiment of the present application. This communication method is applicable to the above-mentioned communication system and mainly involves a management service consumer and a first management service provider. In scenario 3, the management service consumer can request the first management service provider to ensure the communication service quality when moving along a first route within a first time according to network performance requirements, and indicate the network slice to be used. The first management service provider generates a network resource reservation policy based on the request and triggers the configuration of network resources based on the network resource reservation policy.

[0254] As shown in Figure 11, the process of the communication method is as follows:

[0255] 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.

[0256] 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 the network performance requirements, and the first message includes: information for indicating the first time, information for indicating the first route, route planning instructions, network performance requirements, evaluation precision requirements, and slice identification. For details, please refer to the relevant introduction of the aforementioned "S401" and will not be repeated here.

[0257] S1102: The first management service providing entity generates a network resource reservation policy according to the first message.

[0258] S1103: 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.

[0259] S1104: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0260] When the network resource reservation policy is a single policy, the first management service providing entity may trigger the configuration of network resources based on the policy; when the network resource reservation policy includes multiple policies, the first management service providing entity may receive a third message (S1103' in FIG11 ) from the management service consumer indicating an application policy, where the application policy is a policy selected from the network resource reservation policy; and trigger the configuration of network resources based on the application policy.

[0261] It can be understood that the operations of S1101-S1104 are similar to those of 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 relevant introduction of the aforementioned S1001-S1004 and the aforementioned S401-S403, and will not be repeated here.

[0262] For example, Figure 12 is a flowchart of a communication method according to an embodiment of the present application. This method can be applied to the communication between the management service consumer and the first management service providing entity in the above communication system.

[0263] As shown in Figure 12, the process of the communication method is as follows:

[0264] 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.

[0265] 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 service when traveling along the route according to network performance requirements. The network performance requirements can be referred to the relevant introduction of "S401" above and will not be repeated here.

[0266] 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.

[0267] The first time and the information used to indicate the first time can be referred to in the aforementioned description of "S401" and will not be repeated here. The first starting point is the starting point of the terminal's expected movement. The first end point is the end point of the terminal's expected movement. 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 will be understood that the terminals in the embodiments of this application are all terminals that can be managed by the management service consumer.

[0268] The management service consumer can flexibly determine the first time, the first starting point, or the first end point based on the actual situation of the terminal, such as determining the first time based on the expected movement time of the terminal, and / or determining the first starting point and the first end point based on information such as the area where the terminal is expected to move, 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 providing entity, so as to ensure the quality of communication services based on such information.

[0269] It is understood that when the first starting point, the first end point, or the first time is pre-set in the first management service providing entity, the first message may not include information indicating the first starting point, information indicating the first end point, or information indicating the first time. In other words, if the first message does not include information indicating the first starting point, information indicating the first end point, or information indicating the first time, it may indicate that the information indicating the first starting point, the information indicating the first end point, or the information indicating the first time has been pre-set in the first management service providing entity.

[0270] 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.

[0271] 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 and will not be repeated here. It can be understood that in an embodiment of the present application, it is necessary to provide a mobile route, 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.

[0272] A passing point is used to indicate a location that needs to be passed through. The passing point can be represented by longitude and latitude coordinates. In other words, the mobility strategy requested by the management service consumer needs to pass through this location.

[0273] The passing area is used to indicate the area that needs to be passed through. The passing area can be represented by multiple coordinate points constituting the area, or by other methods that can represent the area, without limitation. In other words, the mobility strategy requested by the management service consumer needs to pass through the area.

[0274] A restricted area is used to indicate a location or area that cannot be traversed. The location can be represented by latitude and longitude coordinates, the area can be represented by multiple coordinate points, or any other method that can represent the area. This means that the mobility policy requested by the management service consumer cannot traverse this location or area.

[0275] 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 and there is no restriction.

[0276] The management service consumer can flexibly determine route planning instructions, network performance requirements, evaluation precision requirements, slice identifiers, policy adjustment parameters, optimization stop conditions, transit points, transit areas, restricted areas, and route preferences based on actual conditions. It is understood that the network performance requirements, evaluation precision requirements, policy adjustment parameters, or optimization stop conditions, transit points, transit areas, restricted areas, and route preferences can be pre-set in the first management service providing entity. In this case, the first message may not include this information.

[0277] S1202: The first management service providing entity obtains a network resource reservation policy and a first route according to the first message.

[0278] The network resource reservation policy indicates how the reserved network resources are configured to ensure the quality of communication service during movement along the first route within a first timeframe. For details, refer to the aforementioned "S402" and are not further described here. The first route is the route from the first starting point to the first end point, and the network resource reservation policy is the network resource reservation policy for that route.

[0279] There are multiple ways to obtain the network resource reservation policy and the first route. The first management service provider can obtain the network resource reservation policy and the first route from another entity (such as the second management service provider), or the first management service provider can generate them independently. The following describes each case separately.

[0280] 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.

[0281] In this case, the first management service provider obtaining the network resource reservation policy and the first route based on the first message may specifically include: the first management service provider obtaining the network resource reservation policy and the first route from the second management service provider based on the first message. In other words, the first management service provider can obtain the network resource reservation policy and the first route from the second management service provider, eliminating the need for the first management service provider to generate the network resource reservation policy and the first route based on the first message. This reduces overhead for the first management service provider.

[0282] Specifically, the first management service provider entity obtains the network resource reservation policy 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, and 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 policy according to network performance requirements. 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, which is used to indicate the network resource reservation policy and the first route. Accordingly, the first management service provider entity receives the fifth message from the second management service entity.

[0283] The fourth message can specifically indicate a request for a route from the first starting point to the first end point, and a network resource reservation policy applicable to at least one network element (described below) according to network performance requirements (referred to as request #11), or a request for a route from the first starting point to the first end point, and a guaranteed quality of communication service when traveling along the route according to network performance requirements (referred to as request #22). The specific function of the fourth message is related to the operation of the first management service provider. Specifically, the first management service provider 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. In this case, the fourth message functions as request #11; or the first management service provider can forward the information included in the first message to the second management service provider. In this case, the fourth message functions as request #22. In other words, when the first management service provider performs different processing based on the first message, the corresponding fourth message is different (described below).

[0284] 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.

[0285] The network resource reservation policy, the identifier of the network resource reservation policy, the characteristics of the network resource reservation policy, and the service guarantee satisfaction can be referred to the related introduction of the aforementioned "S402", which will not be repeated here.

[0286] 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, if a route is represented by multiple coordinate points, then the route can be obtained by connecting the multiple coordinate points; or if a route is represented by multiple grids covering the route, then the route can be obtained by connecting lines in the multiple grids in sequence, without limitation. It can be understood that, as shown in Figures 5 and 6, when a route is represented by multiple grids, the higher the fineness of the multiple grids, that is, the smaller the grid size, the more accurately the route can be expressed; correspondingly, if the fineness of the multiple grids is lower, that is, the larger the grid size, the accuracy of the route based on the multiple grid areas is lower. It can also be understood that the first route can be one route or multiple routes.

[0287] It can be understood that in the embodiment of the present application, the first route has a corresponding relationship with the network resource reservation policy, 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 policy. 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 policy in the aforementioned "S402". Please refer to the relevant introduction of the aforementioned "S402" and will not be repeated here.

[0288] 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 first route identifier, 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 these multiple information correspond to the multiple routes respectively.

[0289] For example, the first route includes three routes, identified as Route #1, Route #2, and Route #3, with characteristics as Route Feature #1, Route Feature #2, and Route Feature #3, and service assurance satisfaction as Satisfaction #1, Satisfaction #2, and Satisfaction #3. The network resource reservation policy includes three network resource reservation policies, identified as Policy #1, Policy #2, and Policy #3, with characteristics as Policy Feature #1, Policy Feature #2, and Policy Feature #3. Route #1, Route Feature #1, Satisfaction #1, Policy #1, and Policy Feature #1 correspond to each other; Route #2, Route Feature #2, Satisfaction #2, Policy #2, and Policy Feature #2 correspond to each other; and Route #3, Route Feature #3, Satisfaction #3, Policy #3, and Policy Feature #3 correspond to each other. These correspondences can be sent to the first management service provider by placing different pieces of information in the same tuple, or by other means, without limitation.

[0290] Different situations of the fourth message are described below.

[0291] In the first 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 determine a reservation strategy for network resources applicable to at least one network element according to network performance requirements. The service scope of at least one network element (described below) includes a first area (described below), and the first area includes the first starting point and the first end point.

[0292] Optionally, the fourth message may include at least one of the following: information indicating the first starting point, information indicating the first end point, area information, information indicating at least one network element, or information indicating the first time.

[0293] The information used to indicate the first time, the area information, the at least one network element, and the information used to indicate the at least one network element can refer to the relevant introduction of the aforementioned "S401" and 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" and will not be repeated here.

[0294] It is understood that in the embodiments of the present application, the first area may be the area of ​​the route from the first starting point to the first end point, that is, the first area includes the first starting point and the first end point, that is, the first area may cover the first starting point and the first end point. It is understood that the first area can be determined based on the first starting point and the first end point according to actual circumstances. For example, the size of the first area can be pre-set, and the first area is 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 pre-set, and the first area is determined based on the shape, the first starting point, and the first end point. There is no limitation to this.

[0295] After receiving the first message, the first management service providing 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 this information to the second management service providing entity through a third message, so that the second management service providing entity obtains the network resource reservation strategy and the first route based on the third message.

[0296] 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.

[0297] The first management service provider entity obtains regional information and / or information indicating at least one network element based on the first message. For details, please refer to the aforementioned 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, it can send the regional information and / or information indicating at least one network element to the second management service provider entity, so that the second management service provider entity can obtain the network resource reservation strategy and the first route based on the information. In this way, the second management service provider entity does not need to obtain regional information and / or information indicating at least one network element based on the first message, thereby reducing the overhead of the second management service provider entity.

[0298] Optionally, the fourth message includes at least one of the following: network performance requirements, slice identifiers, policy optimization instructions, policy adjustment parameters, optimization stop conditions, passing points, restricted areas, or route preferences.

[0299] For network performance requirements, slice identification, policy optimization instructions, policy adjustment parameters, and optimization stop conditions, please refer to the relevant introduction of "S401" above and will not be repeated here. For passing points, restricted areas, and route preferences, please refer to the relevant introduction of "S1201" above and will not be repeated here.

[0300] It is understood that the network performance requirements, policy optimization instructions, policy adjustment parameters, optimization stop conditions, transit points, restricted areas, or route preferences may be pre-set in the second management service provider. In this case, the fourth message may not include the network performance requirements, the policy optimization instructions, the policy adjustment parameters, the optimization stop conditions, the transit points, the restricted areas, or the route preferences. In addition, the first management service provider may determine whether to optimize the network resource reservation policy based on actual circumstances, that is, whether to include the policy optimization instruction in the fourth message.

[0301] Optionally, before the second management service providing entity sends a fifth message for indicating the network resource reservation strategy and the first route to the first management service providing entity based on the fourth message, the above-mentioned communication method may also include: the second management service providing entity 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.

[0302] The second management service providing entity constructs 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 repeat it here.

[0303] It is understood that, as shown in Figure 13, after determining each reservation policy for network resources, the second management service providing entity can determine a corresponding route from the first starting point to the first end point based on the policy pre-verification result corresponding to the reservation policy. Specifically, the corresponding route is determined based on the service assurance satisfaction level 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 assurance satisfaction requirements. In this way, the communication service quality of the terminal can be guaranteed when moving along the route within the first time period.

[0304] It can also be understood that the second management service providing entity may assign an identifier to each route when determining the route, and supplement the route feature description and service guarantee satisfaction for the first route when determining the first route.

[0305] 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.

[0306] 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 details on each of these items, refer to the aforementioned description of "S1201" and are not further described here. It will be appreciated that in this scenario, the first management service provider does not process the information indicating the first time or the information indicating the first starting point, but instead forwards these items to the second management service provider via the fourth message. This reduces the overhead of the first management service provider.

[0307] 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.

[0308] Optionally, before the second management service providing entity sends a fifth message for indicating the network resource reservation strategy and the first route to the first management service providing entity based on the fourth message, the above-mentioned communication method may also include: the second management service providing entity 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.

[0309] Specifically, the second management service providing 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 providing 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 providing 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.

[0310] Case 2: The first management service providing entity generates a network resource reservation policy.

[0311] In this case, the first management service provider entity obtaining the network resource reservation policy and the first route based on the first message may specifically include: the first management service provider entity generating the network resource reservation policy and the first route based on the first message. In other words, the first management service provider entity may independently generate the network resource reservation policy and the first route based on the first message without obtaining the network resource reservation policy and the first route from other entities.

[0312] Specifically, the first management service providing entity generates a network resource reservation strategy and a first route based on the first message, which may specifically include: the first management service providing entity obtains regional information and at least one network element based on the information used to indicate the first starting point and the information used to indicate the first end point; the first management service providing entity constructs a network twin model based on the regional information and at least one network element; the first management service providing entity obtains the network resource reservation strategy and the first route through the network twin model based on the first message.

[0313] It is understood that the first management service providing entity obtains 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 aforementioned related introduction and will not be repeated here. In addition, the first management service providing 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. This is similar to the operation of the second management service providing entity. Please refer to the aforementioned related introduction and will not be repeated here.

[0314] S1203: The first management service providing entity sends a second message indicating the network resource reservation policy and the first route to the management service consumer. Correspondingly, the management service consumer receives the second message indicating the network resource reservation policy and the first route from the first management service providing entity.

[0315] The second message may include at least one of the following: a network resource reservation policy, an identifier of the network resource reservation policy, characteristics of the network resource reservation policy, a first route, an identifier of the first route, a service guarantee satisfaction corresponding to the first route, or characteristics of the first route. For each information, please refer to the relevant introduction at the aforementioned "S1202" and will not be repeated here.

[0316] It is understandable that the second message may not include the network resource reservation policy. In other words, the management service consumer does not need to know the specific content of the network resource reservation policy, but only needs to know that the network resource reservation policy has been generated, as well as information such as the characteristics and satisfaction of the network resource reservation policy.

[0317] After obtaining the network resource reservation policy and the first route, the first management service provider can indicate the network resource reservation policy and the first route to the management service consumer via a second message. It is understood that the first route may include at least one route, and the network resource reservation policy may include at least one policy. For details, please refer to the aforementioned description of S1202 and will not be repeated here.

[0318] S1204: The first management service providing entity triggers configuration of network resources according to the network resource reservation policy.

[0319] 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.

[0320] When the network resource reservation policy is a policy, the first management service provider can trigger the configuration of network resources according to the policy. In this case, the first management service provider triggers the configuration of network resources according to the network resource policy (S1204) and the first management service provider sends the second message to the management service consumer according to the network resource reservation policy (S1203) at the same time, or they can be performed in a certain order, such as the first management service provider first triggers the configuration of network resources and then sends the second message to the management service consumer, or the first management service provider first sends the second message to the management service consumer and then triggers the configuration of network resources, without limitation.

[0321] When the network resource reservation policy includes multiple policies, the first management service provider can trigger the configuration of network resources based on a policy selected from the multiple policies. The policy can be selected by the first management service provider or by the management service consumer, without limitation. The specific manner of triggering the configuration of network resources based on the network resource reservation configuration is not limited in this embodiment of the application.

[0322] Optionally, when the network resource reservation policy includes multiple policies, the first management service provider triggering the configuration of network resources according to the network resource reservation policy may specifically include: the first management service provider sending a third message to the management service consumer based on the second message to indicate the application policy, where the application policy is a policy selected from the network resource reservation policy; and the management service consumer correspondingly receives the third message from the first management service provider; and the first management service provider triggering the configuration of network resources based on the application policy. That is, in this case, the first management service provider needs to first send the second message to the management service consumer to indicate the network resource reservation policy and the first route. 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.

[0323] In summary, in this embodiment of the present application, after receiving the first message from the management service consumer, the first management service provider can obtain the first route based on the first message and reserve network resources corresponding to the first route within a first time period, so that the terminal can use these network resources when moving along the first route within the first time period. In this way, the communication service quality of the terminal can be guaranteed while moving along the first route within the first time period.

[0324] Scenario 5:
