Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for communication. Background Technology

[0002] Currently, in order to reduce the management complexity of communication network infrastructure and improve the operation and maintenance efficiency in multi-vendor scenarios, intent-driven management service (IDMS) can be used to achieve the above objectives.

[0003] However, in existing intent-driven management services, because intent consumers cannot know the specific reasons why an intent is not being met, they may randomly adjust the values ​​of intent parameters, potentially resulting in values ​​being set too low. Furthermore, since intent consumers cannot know the reasons for the unmet intent, they can only operate on various fields of the intent based on guesswork to achieve the intent's goal. This results in numerous negotiation rounds between the intent consumer and the intent producer, consuming significant system maintenance resources. Summary of the Invention

[0004] This application provides a communication method and apparatus that enables an intent consumer to obtain detailed operational information about an intent, allows the intent consumer to manage the intent based on the obtained intent fulfillment status, and enables the intent consumer to purposefully adjust the expression values ​​of intent parameters. This avoids situations where the intent consumer is unaware of the specific circumstances under which the intent was not fulfilled, leading to inappropriate adjustments to the expression values ​​of intent parameters, thereby improving the system's operational performance.

[0005] In a first aspect, a communication method is provided, comprising a first device receiving first information from a second device, the first information including information on the evaluation value of the first parameter, the first parameter being a parameter of a first intent; if the evaluation value of the first parameter does not reach the expression value of the first parameter, the first device sending second information to the second device, the second information being used to make the evaluation value of the first parameter reach the expression value of the first parameter.

[0006] In this configuration, the first device deploys the intent consumer module, and the second device deploys the intent producer module. The first device and the second device can be two different devices, in which case the intent consumer module and the intent producer module are deployed on different devices; alternatively, the first device and the second device can be the same device, in which case the intent consumer module and the intent producer module are deployed on the same device.

[0007] Based on the above scheme, the first device receives first information from the second device. This first information includes an evaluation value of a first parameter of a first intent, and, if the evaluation value of the first parameter does not reach its expressed value, the first device sends second information to the second device. The first device is aware of the expressed value of the first parameter. Therefore, the first device can manage the intent based on the evaluation value and the expressed value of the first parameter. For example, it can send information to the second device to ensure that the evaluation value of the first parameter reaches its expressed value. This allows the first device to purposefully adjust the expressed value of the intent parameter, avoiding situations where the first device is unaware of the specific circumstances under which the intent is not satisfied, leading to inappropriate adjustments to the expressed value of the intent parameter and improving system performance.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the first device sends third information to the second device, the third information including information on parameters that the second device needs to feedback, wherein the information on parameters that need to be fed back includes information on the first parameter.

[0009] Based on the above scheme, the first device can send information to the second device indicating the parameters that the second device needs to provide feedback. This allows the second device to provide feedback on the corresponding parameters to the first device, enabling the first device to understand why the parameters of the intent are not met. This avoids the situation where the first device can only operate on the fields of the intent based on guesswork, resulting in a large number of negotiation attempts with the second device. This saves system maintenance resources and improves system performance.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the first information further includes modification instruction information, which includes information about the expression of some or all of the parameters of the first parameter after modification.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the second information is also used to instruct the first device to accept modification of some or all of the parameters of the first parameter.

The first creation request information is used to request the creation of a second intent, the parameters of the second intent include at least one of the parameters of the first parameter, and the first modification request information is used to indicate the modification of the expression value of at least one of the parameters of the first parameter.

[0013] Based on the above scheme, the first device can send at least one first creation request information and / or a first modification request information to the second device to create an intent and / or adjust the expression value of the intent parameters, so that the intent can be satisfied and the system's operating performance can be improved.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the second information is also used to instruct the first device not to accept modifications to some or all of the parameters of the first parameter.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the second information includes a second modification request information and / or at least one second creation request information.

The second creation request information is used to indicate the creation of a third intent, the parameters of which include the parameters in the first parameter whose evaluation value has not reached the expression value.

[0016] Based on the above scheme, the first device can adjust the expression value of the intent parameter and / or create a new intent by sending at least one second modification request message and / or a second creation request message to the second device, so that the intent can be satisfied and the system's operating performance can be improved.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the first parameter includes at least one of the following parameters: target, constraint, area of ​​action, preference information, or time of achievement.

Figure 1 As shown, the architecture of this intent can be called a wireless intent-driven network (WIDN) architecture. In actual deployment, the intent instance base and intent schema base can be deployed together with intent management as sub-functions of intent management; the intent knowledge base can be deployed together with knowledge management as a sub-function of knowledge management.

[0073] The intent instance library stores intent instances; the intent pattern library stores intent patterns; intent management manages intent patterns and intent instances; the intent knowledge base stores intent knowledge; knowledge management manages intent knowledge; and the consumer of intents can be a business support system (OSS), an operations support system (BSS), an application (APP), or a third-party user.

[0081]

[0082] Among them, the functional modules in the wIDN architecture and ENI architecture can serve as sub-modules of services in the IDMS architecture.

[0083] It should be understood that the above Figures 1 to 3 This is merely an illustrative example and is not intended to limit the scope of this application.

[0084] It should also be understood that the network device involved in this application can be any device with wireless transceiver capabilities. This equipment includes, but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home base station (e.g., Home evolved Node B, or HomeNode B, HNB), Base Band Unit (BBU), Access Point (AP), Wireless Relay Node, Wireless Backhaul Node, Transmission Point (TP), or Transmission and Reception Point (TRP) in a Wireless Fidelity (WIFI) system. It can also be a gNB in ​​a 5G system, such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a Base Band Unit (BBU) or a Distributed Unit (DU).

[0085] In some deployments, a gNB may include a centralized unit (CU) and a distribution unit (DU). A gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU handles non-real-time protocols and services, implementing radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions. The DU handles physical layer protocols and real-time services, implementing radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can be considered to be sent by the DU, or by the DU+AAU. It is understood that network devices can be devices that include one or more of the following: CU nodes, DU nodes, and AAU nodes. In addition, the CU can be classified as a network device in the radio access network (RAN) or as a network device in the core network (CN), and this application does not limit this.

[0086] In this embodiment, the functions of a network device can also be implemented through multiple network function entities, each of which is used to implement a portion of the functions of the network device. These network function entities can be network elements in hardware devices, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform).

[0087] To facilitate understanding of the embodiments of this application, the following is a brief introduction to several terms involved in this application.

[0088] 1. Intent

[0089] Intent refers to expectations for a system, including requirements, goals, and constraints for the system, but excluding the process of how to satisfy these parameters. In this application, the following concepts related to intent are included:

[0090] (1) Intent Fulfil Status: This is the status of the intent fulfillment result. This status is configured by the management service (MNS) producer (intent producer) and obtained by the MNS consumer (intent consumer).

[0091] (2) Intent expression: An expression used to carry an intent. This expression includes the action name of the intent, the action attribute of the intent, the name of the object to which the intent is applied, and the attribute of the object to which the intent is applied. It has specific syntax and semantics.

[0092] (3) Intent translation: The process of converting intents into executable commands / sub-intents / rules of intents.

[0093] (4) Intent decision and execution: Select the executable command / sub-intent / rule of intent based on the network environment and intent achievement status, and issue the selected executable command / sub-intent / rule of intent.

[0094] (5) Executable commands of intent: refers to a series of instructions formed by the translation and decision-making processes of intent.

[0095] (6) Intent creation: Create a new intent instance in the intent system and create the corresponding intent context.

[0096] (7) Intent maintenance: Adjust the executable commands of intent according to changes in the network environment, so as to achieve the intent goal as much as possible.

[0097] (8) Intent Achievement: The intent system detects that the key performance indicator (KPI) value in the network has reached the target value in the intent expression.

[0098] (9) Intention state: Identifies the state of the intention, including active state, deactivated state, conflict state, dormant state, etc.

[0099] (10) Intent knowledge base: A database used to store historical experience and intent knowledge needed for translation.

[0100] (11) Intent Pattern: Specifies the syntax and semantics of intent expressions, including which fields, the range of values ​​for each field, the type of each field, and the hierarchical relationship between fields.

[0101] (12) Conflict of intent: When two intents cannot be achieved simultaneously due to mutual exclusion in intent expression, execution command or semantics, the two intents are said to be in conflict.

[0102] (13) Syntactic conflict: refers to a conflict between two intentions in their expressions. For example, if two intentions describe mutually exclusive desired goals for the same target (cell, base station, etc.) under the same effective conditions, then the two intentions have a syntactic conflict.

[0103] (14) Semantic conflict: refers to the inherent conflict between the internal interpretations of intention and goal. It is difficult to identify at the level of intention expression and intention execution, and is a deeper conflict between intentions.

[0104] (15) Operation conflict: refers to the conflict between two intentions in the translated execution operation, that is, the operations of the two intentions cannot be executed at the same time.

[0105] 2. Network Management System

[0106] A network management system (NMS) is a management system responsible for the operation, management, and maintenance of a network. Its managed objects can include entities within the network, such as network devices, applications, server systems, routers, switches, hubs, and auxiliary equipment (such as uninterruptible power supply systems), providing a comprehensive network view. NMS offers operators a way to manage networks across different regions and equipment vendors. Network administrators can use NMS to comprehensively monitor the network's operational status, enabling better management and maintenance. NMS improves network availability and reliability, thereby enhancing overall network efficiency and reducing management costs.

[0107] 3. Network Element Management System

[0108] An element management system (EMS) is a system that manages one or more telecommunications network elements (NEs) of a specific type. Generally, the EMS manages the functions and capacity of each NE, but does not participate in communication between different NEs in the network.

[0109] To support communication between NEs, EMS needs to communicate with the higher-level NMS. EMS is based on the operation-support system (OSS) architecture of the telecom management network (TMN) hierarchical model. This architecture enables service providers (SPs) to meet customers' rapidly evolving service demands while also meeting high standards of quality of service (QoS) requirements.

[0110] EMS provides unified operation and maintenance functions in the professional network field, focusing on network element management within regions, networks, and subnetworks, and enabling end-to-end management and maintenance of equipment and networks. For example, an EMS can be used to centrally manage an operator's IP multimedia subsystem (IMS) network and equipment, including: core network equipment, data communication equipment, next-generation network (NGN) equipment, service equipment, and third-party information technology (IT) equipment.

[0111] Currently, traditional northbound interfaces (ITF-N) are defined using a method of full network resource modeling and full network object management. NMS (Network Management System) adds, deletes, modifies, and checks all southbound managed objects through configuration management, performance management, and fault management operations. However, this approach not only raises the management and maintenance threshold for operators but also exposes the differences between equipment vendors, making interoperability between different vendors difficult.

[0112] To reduce the management complexity of network infrastructure and improve operational efficiency in multi-vendor scenarios, intent-driven management services have been introduced. Their main approach can be summarized as follows:

[0113] NMS does not directly manage network resource management (NRM), but only retains the intent model. It only transmits vendor-agnostic intent expressions on the northbound interface, thereby avoiding the problem of differences in equipment vendor implementations.

[0114] The intent is expressed in a declarative manner, that is, it only describes what (what) without involving how (how). Only basic conceptual knowledge in the wireless field is required to complete the intent expression, thereby reducing the operation and maintenance threshold.

[0115] Once EMS receives an intent, it needs to translate it into network requirements and specific execution operations based on the network status, and then execute it to achieve the intent.

[0116] However, in the current technology, the intent consumer can only obtain whether the intent has been fulfilled. When the intent has not been fulfilled, since the intent consumer does not know the reason why the intent was not fulfilled, it can only operate on the various fields of the intent based on guesses and negotiate with the intent producer, resulting in a high number of negotiations and unnecessary consumption of operation and maintenance resources. At the same time, since the adjustment of the intent target is random, the intent target may be adjusted too low during the process of intent consumer adjustment.

[0117] In view of this, this application provides a communication method and apparatus that can improve the above-mentioned problems.

[0118] It should be understood that in the following embodiments, the first device deploys an intent consumer module and the second device deploys an intent producer module. The first device and the second device can be two different devices, in which case the intent consumer module and the intent producer module are deployed on different devices; or the first device and the second device can be the same device, in which case the intent consumer module and the intent producer module are deployed on the same device.

[0119] Figure 4 This is a schematic diagram of the communication method 400 provided in an embodiment of this application. For example... Figure 4 As shown, the method 400 includes the following steps:

[0120] S410, the second device sends first information to the first device. Correspondingly, the first device receives the first information from the second device.

[0121] For example, the second device may send first information to the first device, the first information including information on the evaluation value of a first parameter, the first parameter being a parameter of a first intent.

[0122] Specifically, the second device can send first information to the first device, enabling the first device to obtain information on whether the evaluation value of the first parameter has reached the expression value of the first parameter. The first device is aware of the expression value of the first parameter. The evaluation value of the first parameter refers to the numerical value of the first parameter in the real-time network evaluation of the first intent, and the expression value of the first parameter refers to the numerical value of the expression of the first parameter in the first intent. When the evaluation value of the first parameter reaches the expression value of the first parameter, the first intent can be considered satisfied or achieved; when the evaluation value of the first parameter does not reach the expression value of the first parameter, the first intent can be considered not satisfied or not achieved. The first parameter includes at least one of the following: target, constraint, area of ​​action, preference information, or achievement time. Furthermore, the target refers to the state that the intention hopes to achieve. For example, in a throughput optimization intention, the target could be "throughput greater than 10kbps," and in a latency optimization intention, the target could be "end-to-end latency less than 10ms." Constraints refer to the limiting conditions that need to be followed in achieving the intention's target. For example, in a network deployment intention, constraints could be frequency information, transmission information, etc. The area of ​​effect is the region where the intention applies. For example, in a coverage optimization intention, the area of ​​effect might be "Chaoyang District, Beijing." Preference information refers to the preferred or prioritized target objects in the process of achieving the intention. For example, in an area where both 5G and 4G base stations exist, and throughput needs to be improved, preference information can be used to prioritize improving the throughput of 5G base stations. The time of achievement refers to the time period during which the intention is achieved. For example, an energy-saving intention aims to be achieved between 1:00 AM and 2:00 AM.

[0123] In one implementation, when the first parameter is a target, the first information may include information about the target's evaluation value. For example, if the target's evaluation value is 8 and the target's expression value is 10, then the target's evaluation value has not reached the target's expression value, and the first intention is considered not to have been satisfied; if the target's evaluation value is 10 and the target's expression value is also 10, then the target's evaluation value has reached the target's expression value, and the first intention is considered to have been satisfied.

[0124] In one implementation, when the first parameter is a constraint, the first information may include information about the constraint's evaluation value. For example, if the constraint's evaluation value is 6 and its expression value is 8, then the constraint's evaluation value has not reached the constraint's expression value, and the first intent is considered not satisfied; if the constraint's evaluation value is 8 and its expression value is also 8, then the constraint's evaluation value has reached the constraint's expression value, and the first intent is considered satisfied.

[0125] In one implementation, when the first parameter is a scope, the first information may include information about the evaluation value of the scope. For example, if the evaluation value of the scope is 5 and the expression value of the scope is 6, then the evaluation value of the scope does not reach the expression value of the scope, and the first intent is considered not to be satisfied; if the evaluation value of the scope is 5 and the expression value of the scope is also 5, then the evaluation value of the scope reaches the expression value of the scope, and the first intent is considered to be satisfied.

[0126] In one implementation, when the first parameter is the achievement time, the first information may include information about the evaluation value of the achievement time. For example, if the evaluation value of the achievement time is 8 and the expression value of the achievement time is 9, then the evaluation value of the achievement time has not reached the expression value of the achievement time, and the first intention is considered not to have been satisfied; if the evaluation value of the achievement time is 8 and the expression value of the achievement time is also 8, then the evaluation value of the achievement time has reached the expression value of the achievement time, and the first intention is considered to have been satisfied.

[0127] In one implementation, when the first parameter is preference information, the first information may include the evaluation value of the preference information. For example, if the evaluation value of the preference information is 4 and the expression value of the preference information is 7, then the evaluation value of the preference information does not reach the expression value of the preference information, and the first intention is considered not to be satisfied; if the evaluation value of the preference information is 7 and the expression value of the preference information is also 7, then the evaluation value of the preference information reaches the expression value of the preference information, and the first intention is considered to be satisfied.

[0128] In one implementation, when the first parameter is a target and an area of ​​effect, the first information may include information about the evaluation values ​​of the target and the area of ​​effect. For example, if the evaluation values ​​of the target and the area of ​​effect are 6 and 7 respectively, and the expression values ​​of the target and the area of ​​effect are 9 and 10 respectively, then the evaluation value of the target and the area of ​​effect does not reach the expression value of the target and the area of ​​effect, and therefore the first intention is considered not satisfied; if the evaluation values ​​of the target and the area of ​​effect are 9 and 7 respectively, and the expression values ​​of the target and the area of ​​effect are 9 and 10 respectively, then the evaluation value of the area of ​​effect does not reach the expression value of the area of ​​effect, and therefore the first intention is considered not satisfied; if the evaluation values ​​of the target and the area of ​​effect are 6 and 7 respectively, and the expression values ​​of the target and the area of ​​effect are 6 and 7 respectively, then the evaluation value of the target and the area of ​​effect reaches the expression value of the target and the area of ​​effect, and therefore the first intention is considered satisfied.

[0129] In one implementation, when the first parameter is a goal and an achievement time, the first information may include the evaluation values ​​of the goal and the achievement time. For example, if the evaluation values ​​of the goal and the achievement time are 3 and 5 respectively, and the expression values ​​of the goal and the achievement time are 6 and 6 respectively, then the evaluation values ​​of the goal and the achievement time have not reached the expression values ​​of the goal and the achievement time, and the first intention is considered not to be satisfied; if the evaluation values ​​of the goal and the achievement time are 6 and 4 respectively, and the expression values ​​of the goal and the achievement time are 6 and 8 respectively, then the evaluation value of the achievement time has not reached the expression value of the achievement time, and the first intention is considered not to be satisfied; if the evaluation values ​​of the goal and the achievement time are 5 and 5 respectively, and the expression values ​​of the goal and the achievement time are 5 and 5 respectively, then the evaluation value of the goal and the achievement time has reached the expression values ​​of the goal and the achievement time, and the first intention is considered to be satisfied.

[0130] In one implementation, when the first parameter is the achievement time and the area of ​​effect, the first information may include information about the evaluation values ​​of the achievement time and the area of ​​effect. For example, if the evaluation values ​​of the achievement time and the area of ​​effect are 7 and 8 respectively, and the expression values ​​of the achievement time and the area of ​​effect are 9 and 10 respectively, then the evaluation value of the achievement time and the area of ​​effect has not reached the expression value of the achievement time and the area of ​​effect, and the first intention is considered not to be satisfied; if the evaluation values ​​of the achievement time and the area of ​​effect are 7 and 8 respectively, and the expression values ​​of the achievement time and the area of ​​effect are 7 and 10 respectively, then the evaluation value of the area of ​​effect has not reached the expression value of the area of ​​effect, and the first intention is considered not to be satisfied; if the evaluation values ​​of the achievement time and the area of ​​effect are 6 and 8 respectively, and the expression values ​​of the achievement time and the area of ​​effect are 6 and 8 respectively, then the evaluation value of the achievement time and the area of ​​effect has reached the expression value of the achievement time and the area of ​​effect, and the first intention is considered to be satisfied.

[0131] In one implementation, when the first parameter is a target, an achievement time, and an area of ​​effect, the first information may include the evaluation values ​​of the target, the achievement time, and the area of ​​effect. For example, if the evaluation values ​​of the target, the achievement time, and the area of ​​effect are 3, 4, and 5 respectively, and the expression values ​​of the target, the achievement time, and the area of ​​effect are 6, 7, and 8 respectively, then the evaluation values ​​of the target, the achievement time, and the area of ​​effect have not been reached, and the first intention is considered not to have been satisfied. If the evaluation values ​​of the target, the achievement time, and the area of ​​effect are 6, 7, and 8 respectively, and the expression values ​​of the target, the achievement time, and the area of ​​effect are 6, 7, and 10 respectively, then the evaluation value of the area of ​​effect has not been reached, and the first intention is considered not to have been satisfied. If the evaluation values ​​of the target, the achievement time, and the area of ​​effect are 3, 5, and 8 respectively, and the expression values ​​of the target, the achievement time, and the area of ​​effect are 3, 5, and 8 respectively, then the evaluation values ​​of the target, the achievement time, and the area of ​​effect have been reached, and the first intention is considered to have been satisfied.

[0132] Optionally, before S410, method 400 further includes S401, that is, the first device sends third information to the second device. Correspondingly, the second device receives the third information from the first device.

[0133] Specifically, the first device can send a third message to the second device, which includes information about parameters that the second device needs to provide feedback on, including information about the first parameter.

[0134] Furthermore, the third information can be an intent creation request information sent by the first device to the second device, used to request the second device to create a first intent. This intent creation request information also includes information about the first intent, such as information about the expression of the first parameter.

[0135] Furthermore, after receiving the third information from the first device, the second device can calculate the achievement status of the parameter to be fed back based on the information of the parameter to be fed back, the expression of the first parameter, and the evaluation value of the first parameter. The achievement status of the parameter to be fed back can be reflected by the specific numerical values ​​of the evaluation value and the expression value of the parameter to be fed back.

[0136] In one implementation, the third information, including the information of the parameters that need to be fed back, can be the identification information of the parameters that need to be fed back.

[0137] S420, if the evaluated value of the first parameter does not reach the expressed value of the first parameter, the first device sends second information to the second device. Correspondingly, the second device receives the second information from the first device.

[0138] For example, after receiving the first information, the first device determines whether the evaluated value of the first parameter reaches the expressed value of the first parameter. If the evaluated value of the first parameter does not reach the expressed value of the first parameter, the first device sends second information to the second device based on the first information, the second information being used to make the evaluated value of the first parameter reach the expressed value of the first parameter.

[0139] In one possible implementation, the first information includes information about the evaluated value of the first parameter, which may be the specific situation regarding whether the evaluated value of the first parameter achieves the expressed value of the first parameter (e.g., the numerical value of the evaluated value of the first parameter). This allows the first device to determine whether the evaluated value of the first parameter achieves the expressed value of the first parameter based on the specific situation regarding whether the evaluated value of the first parameter achieves the expressed value of the first parameter, wherein the first device is aware of the expressed value of the first parameter. If the evaluated value of the first parameter does not achieve the expressed value of the first parameter, the first device sends second information to the second device, which is used to make the evaluated value of the first parameter achieve the expressed value of the first parameter.

[0140] In another possible implementation, prior to S410, method 400 also includes S402, whereby the second device modifies the expression of some or all of the parameters of the first parameter.

[0141] Specifically, after calculating the achievement of the first parameter, the second device can modify the expression of the parameter whose evaluation value in the first parameter has not reached the expression value based on the achievement of the first parameter.

[0142] Subsequently, the second device can add modification instruction information to the first information sent to the first device. The modification instruction information includes information on the expression of some or all of the parameters of the modified first parameter, that is, the expression of the parameters in the modified first parameter whose evaluation value has not reached the expression value.

[0143] After receiving the first information containing modification instruction information, the first device may accept or reject the modification of some or all of the expressions of the first parameter by the second device.

[0144] On the one hand, when the first device accepts some or all of the modifications to the first parameter, the second information sent by the first device to the second device is also used to instruct the first device to accept the modifications made by the second device to some or all of the first parameter.

[0145] Furthermore, the method 400 further includes S421, namely, the first device sends at least one first creation request information and / or a first modification request information to the second device. Correspondingly, the second device receives at least one first creation request information and / or a first modification request information from the first device.

[0146] Specifically, after the first device accepts modifications to some or all of the parameters of the first parameter, the second information sent by the first device to the second device further instructs the first device to accept the modifications to some or all of the parameters of the first parameter. Furthermore, the first device may send at least one first creation request message and / or a first modification request message to the second device. The first creation request message requests the creation of a second intent, the parameters of which include at least one parameter from the first parameter. The first modification request message instructs the modification of the expression value of at least one parameter from the first parameter.

[0147] For example, the first parameter of the first intent is the target and the achievement time. If the modification instruction information sent by the second device to the first device includes the modification information of the target but does not include the modification information of the achievement time, the first device can send the first modification request information to the second device. The first modification request information can indicate the modification of the expression value of the achievement time in the first parameter.

[0148] For example, the first parameters of the first intent are the target, the achievement time, and the area of ​​effect. If the modification instruction information sent by the second device to the first device includes modification information for the target and the achievement time, but does not include modification information for the area of ​​effect, then the first device can send a first creation request information to the second device. The first creation request information indicates the creation of a second intent, and the parameters of the second intent include the area of ​​effect parameter in the first parameters.

[0149] Specifically, when the expression values ​​of the parameters whose evaluation values ​​do not reach the expression values ​​in the first parameter are the same, a new request message can be sent; when the expression values ​​of the parameters whose evaluation values ​​do not reach the expression values ​​in the first parameter are different, more than one new request message can be sent.

[0150] It should be understood that in the above scheme, if the first device accepts all the parameter modifications in the first parameter by the intent management module of the second device, then the first device can send only the second information to the second device, without needing to send at least one first creation request information and / or first modification request information to the intent management module of the second device.

[0151] On the other hand, if the first device does not accept modifications to some or all of the parameters of the first parameter, the first device may send second information to the second device so that the evaluation value of the first parameter reaches the expression value of the first parameter.

[0152] In the above technical solution, the second information includes a second modification request information and / or at least one second creation request information. The second modification request information is used to indicate the modification of the expression value of the parameter whose evaluation value in the first parameter has not reached the expression value. The second creation request information is used to indicate the creation of a third intent. The parameters of the third intent include the parameters whose evaluation value in the first parameter has not reached the expression value.

[0153] For example, if the first parameter of the first intent is the target and the achievement time, and if the modification instruction information sent by the second device to the first device includes modification information of the target and the achievement time, then the first device can send a second modification request information to the second device. The second modification request information can indicate the modification of the expression value of the target and the expression value of the achievement time in the first parameter.

[0154] For example, the first parameter of the first intent is the target and the area of ​​effect. If the modification instruction information sent by the second device to the first device includes modification information of the target, the time of achievement, and the area of ​​effect, then the first device can send a second creation request information to the second device. The second creation request information indicates the creation of a third intent. The parameters of the third intent include the target and area of ​​effect parameters in the first parameter.

[0155] In the above scheme, if the first device does not accept the modification of the expression of all or part of the parameters of the first parameter, the first device may also send a second message to the second device, which is used to instruct the second device to continue to use the first intention for communication.

[0156] It should be understood that in the above scheme, when the expression values ​​of parameters whose evaluation values ​​do not reach the expression values ​​are the same within the first parameter, a new request message can be sent; when the expression values ​​of parameters whose evaluation values ​​do not reach the expression values ​​are different within the first parameter, more than one new request message can be sent.

[0157] It should also be understood that, unless otherwise specified, there are no restrictions on the order of the steps in the above scheme, nor are there any restrictions on the causal relationship or other logical relationship between them, and some steps are optional. This application does not limit the implementation method.

[0158] Based on the above scheme, the first device receives first information from the second device. This first information includes the evaluation value of the first parameter of the first intent, and, if the evaluation value of the first parameter does not reach the expression value of the first parameter, the first device sends information to the second device to make the evaluation value of the first parameter reach the expression value of the first parameter. Thus, the first device can manage the intent based on the evaluation value and expression value of the first parameter of the first intent. For example, by sending information to the second device to make the evaluation value of the first parameter reach the expression value of the first parameter, the first device can purposefully adjust the expression value of the intent parameter to satisfy the intent, avoiding situations where the first device cannot know the specific circumstances under which the intent is not satisfied, leading to inappropriate adjustments to the expression value of the intent parameter. Furthermore, the first device can send information to the second device instructing the second device to provide feedback on the parameters, allowing the second device to provide feedback on the corresponding parameters. This enables the first device to understand the reason why the intent parameters are not satisfied, avoiding situations where the first device can only operate on the various fields of the intent based on guesswork, resulting in numerous negotiation attempts with the second device. This saves system maintenance resources and improves system performance.

[0159] Figure 5 This is a schematic diagram of the communication method 500 provided in an embodiment of this application. For example... Figure 5 As shown, the method 500 includes the following steps:

[0160] S501, the first device sends third information to the intent management module of the second device. Correspondingly, the intent management module of the second device receives the third information from the first device.

[0161] For example, the first device may send third information to the intent management module of the second device. The third information includes information about the parameters that the second device needs to return, wherein the information about the parameters that need to be returned includes information about the first parameter, which is a parameter of the first intent.

[0162] The descriptions of the first parameter and the third information can be found in the descriptions of the first parameter and the third information in S410 above. For the sake of brevity, these descriptions will not be repeated here.

[0163] S502, the intent management module of the second device sends intent translation information to the intent translation module of the second device. Correspondingly, the intent translation module of the second device receives the intent translation information from the intent management module of the second device.

[0164] For example, after receiving the third information from the first device, the intent management module of the second device can send intent translation information to the intent translation module of the second device. The intent translation information includes information about the parameters that need to be fed back, as well as information about the expression of the first parameter.

[0165] In one implementation, the information of the parameter that needs to be fed back can be the identification information of the parameter that needs to be fed back.

[0166] S503, the intent translation module of the second device sends intent execution notification information to the intent decision and execution module of the second device. Correspondingly, the intent decision and execution module of the second device receives the intent execution notification information from the intent translation module of the second device.

[0167] For example, after receiving intent translation information from the intent management module of the second device, the intent translation module of the second device can send intent execution notification information to the intent decision and execution module of the second device. The intent execution notification information includes information about the parameters that need to be fed back, as well as information about the expression of the first parameter.

[0168] S504, the intention decision and execution module of the second device calculates the achievement status of the parameters that need to be fed back.

[0169] For example, after receiving an intent to execute notification message containing information about the parameters that need to be fed back and information about the expression of the first parameter, the second device can, in conjunction with the evaluation value of the first parameter, calculate the achievement status of the parameters that need to be fed back, based on the information about the parameters that need to be fed back, the expression of the first parameter, and the evaluation value of the parameters that need to be fed back.

[0170] In one implementation, the achievement status of the parameter that needs feedback can be reflected by the specific values ​​of the evaluation value and the expression value of the parameter that needs feedback.

[0171] S505, the intent decision and execution module of the second device sends intent context update information to the intent management module of the second device. Correspondingly, the intent management module of the second device receives the intent context update information from the intent decision and execution module of the second device.

[0172] For example, after calculating the achievement status of the parameters that need to be fed back, the intent decision and execution module of the second device can send intent context update information to the intent management module of the second device. The intent context update information includes information on the achievement status of the parameters that need to be fed back.

[0173] S506, the intent management module of the second device sends first information to the first device. Correspondingly, the first device receives the first information from the intent management module of the second device.

[0174] For example, after receiving the intent context update information, the intent management module of the second device can send first information to the first device, which includes information about the evaluation value of the first parameter. For example, it could be information about the specific numerical value of the evaluation value of the first parameter.

[0175] Specifically, for the description of the first information, please refer to the relevant description of the first information in S410 above. For the sake of brevity, this application will not repeat it here.

[0176] S507, if the evaluated value of the first parameter does not reach the expressed value of the first parameter, the first device sends second information to the second device. Correspondingly, the second device receives the second information from the first device.

[0177] For example, after receiving the first information, the first device determines whether the evaluated value of the first parameter reaches the expressed value of the first parameter, wherein the first device is aware of the expressed value of the first parameter. If the evaluated value of the first parameter does not reach the expressed value of the first parameter, the first device sends second information to the second device based on the first information. This second information is used to make the evaluated value of the first parameter reach the expressed value of the first parameter. For example, the second information can be used to instruct the first device to accept modifications to some or all of the parameters of the first parameter.

[0178] Specifically, the first device can determine whether the evaluation value of the first parameter has reached the expressed value of the first parameter based on whether the evaluation value of the first parameter has reached the expressed value of the first parameter. If the evaluation value of the first parameter has not reached the expressed value of the first parameter, the first device sends second information to the second device, which is used to make the evaluation value of the first parameter reach the expressed value of the first parameter.

[0179] The second information includes a second modification request and / or at least one second creation request. The second modification request is used to indicate the modification of the expression value of the parameter whose evaluation value in the first parameter has not reached the expression value. The second creation request is used to indicate the creation of a third intent. The parameters of the third intent include the parameters whose evaluation value in the first parameter has not reached the expression value.

[0180] It should be understood that in the above scheme, when the expression values ​​of parameters whose evaluation values ​​do not reach the expression values ​​are the same within the first parameter, a new request message can be sent; when the expression values ​​of parameters whose evaluation values ​​do not reach the expression values ​​are different within the first parameter, more than one new request message can be sent.

[0181] It should also be understood that, unless otherwise specified, there are no restrictions on the order of the steps in the above scheme, nor are there any restrictions on the causal relationship or other logical relationship between them, and some steps are optional. This application does not limit the implementation method.

[0182] Based on the above scheme, by adding information elements to the intent translation information and intent execution notification information, the parameters that the second device needs to feed back can be indicated; by adding information elements to the intent context update information, the achievement status of the calculated parameters that need to be fed back can be indicated.

[0183] Furthermore, the first device receives first information from the intent management module of the second device. If the evaluation value of the first parameter does not reach the expression value of the first parameter, the first device sends second information to the intent management module of the second device. Thus, the first device can manage the intent based on the evaluation value and expression value of the first parameter of the first intent. For example, it can send information to the intent management module of the second device to make the evaluation value of the first parameter reach the expression value of the first parameter, so that the first device can purposefully adjust the expression value of the intent parameter to satisfy the intent. This avoids the situation where the first device cannot know the specific circumstances of the unmet intent, resulting in an inappropriate adjustment of the expression value of the intent parameter. In addition, the first device can send information to the intent management module of the second device instructing the second device to provide feedback on the parameters. This allows the intent management module of the second device to provide feedback on the corresponding parameters to the first device, avoiding the situation where the first device can only operate on the various fields of the intent based on guesswork, resulting in a large number of negotiation times with the second device. This saves system maintenance resources and improves system performance.

[0184] Figure 6 This is a schematic diagram of the communication method 600 provided in an embodiment of this application. For example... Figure 6 As shown, the method 600 includes the following steps:

[0185] S601, the first device sends third information to the intent management module of the second device. Correspondingly, the intent management module of the second device receives the third information from the first device.

[0186] For example, the first device may send third information to the intent management module of the second device. The third information includes information about the parameters that the second device needs to return, wherein the information about the parameters that need to be returned includes information about the first parameter, which is a parameter of the first intent.

[0187] The descriptions of the first parameter and the third information can be found in the descriptions of the first parameter and the third information in S410 above. For the sake of brevity, these descriptions will not be repeated here.

[0188] S602, the intent management module of the second device sends intent translation information to the intent translation module of the second device. Correspondingly, the intent translation module of the second device receives the intent translation information from the intent management module of the second device.

[0189] For example, after receiving the third information from the first device, the intent management module of the second device can send intent translation information to the intent translation module of the second device. The intent translation information includes information about the parameters that need to be fed back, as well as information about the expression of the first parameter.

[0190] In one implementation, the information of the parameter that needs to be fed back can be the identification information of the parameter that needs to be fed back.

[0191] S603, the intent translation module of the second device sends intent execution notification information to the intent decision and execution module of the second device. Correspondingly, the intent decision and execution module of the second device receives the intent execution notification information from the intent translation module of the second device.

[0192] For example, after receiving intent translation information from the intent management module of the second device, the intent translation module of the second device can send intent execution notification information to the intent decision and execution module of the second device. The intent execution notification information includes information about the parameters that need to be fed back, as well as information about the expression of the first parameter.

[0193] S604, the intention decision and execution module of the second device calculates the achievement status of the parameters that need to be fed back.

[0194] For example, after receiving an intent to execute notification message containing information about the parameters that need to be fed back and information about the expression of the first parameter, the second device can, in conjunction with the evaluation value of the first parameter, calculate the achievement status of the parameters that need to be fed back, based on the information about the parameters that need to be fed back, the expression of the first parameter, and the evaluation value of the parameters that need to be fed back.

[0195] In one implementation, the achievement status of the parameter that needs feedback can be reflected by the specific values ​​of the evaluation value and the expression value of the parameter that needs feedback.

[0196] S605, the intent decision and execution module of the second device sends intent context update information to the intent management module of the second device. Correspondingly, the intent management module of the second device receives the intent context update information from the intent decision and execution module of the second device.

[0197] For example, after calculating the achievement status of the parameters that need to be fed back, the intent decision and execution module of the second device can send intent context update information to the intent management module of the second device. The intent context update information includes information on the achievement status of the parameters that need to be fed back.

[0198] S606, The intent management module of the second device modifies the expression of some or all of the parameters of the first parameter.

[0199] Specifically, after receiving the intent context update information, the intent management module of the second device can modify the expression of the parameter whose evaluation value in the first parameter has not reached the expression value according to the achievement of the first parameter.

[0200] S607, the intent management module of the second device sends first information to the first device. Correspondingly, the first device receives the first information from the intent management module of the second device.

[0201] For example, after the intent management module of the second device modifies the expression of the parameter whose evaluation value has not reached the expression value in the first parameter, it can send first information to the first device. The first information includes information about the evaluation value of the first parameter and modification instruction information. The modification instruction information includes information about the expression of some or all of the parameters of the first parameter after modification, that is, the expression of the parameter whose evaluation value has not reached the expression value in the first parameter after modification.

[0202] S608, if the evaluated value of the first parameter does not reach the expressed value of the first parameter, the first device sends second information to the intent management module of the second device. Correspondingly, the intent management module of the second device receives the second information from the first device.

[0203] For example, after receiving the first information, the first device can determine whether the evaluated value of the first parameter reaches the expressed value of the first parameter, wherein the first device is aware of the expressed value of the first parameter. If the evaluated value of the first parameter does not reach the expressed value of the first parameter, the first device sends second information to the intent management module of the second device, the second information being used to make the evaluated value of the first parameter reach the expressed value of the first parameter.

[0204] Specifically, after receiving the first information, the first device can determine whether the evaluated value of the first parameter reaches the expressed value of the first parameter. Further, the first information includes modification instruction information, and the first device can accept or reject modifications made by the intent management module of the second device to the expression of some or all of the first parameter's parameters.

[0205] In one implementation, if the first device does not accept modifications to some parameters of the first parameter, the first device may send second information to the intent management module of the second device. This second information includes at least one second creation request and / or a second modification request. The second modification request indicates modification of the expression value of at least one parameter in the first parameter, and the second creation request indicates creation of a third intent, the parameters of which include at least one parameter from the first parameter.

[0206] It should be understood that in the above scheme, if the first device does not accept the modification of the expression of all parameters of the first parameter, the first device may also send a second message to the intent management module of the second device, which is used to instruct the second device to continue to use the first intent for communication.

[0207] S609, if the first device receives a modification to some parameters of the first parameter, it sends at least one first creation request message and / or a first modification request message to the intent management module of the second device. Correspondingly, the intent management module of the second device receives at least one first creation request message and / or a first modification request message from the first device.

[0208] For example, the first device may send at least one first creation request and / or first modification request to the intent management module of the second device.

[0209] In this context, the second information sent by the first device to the intent management module of the second device, when it receives modifications to some or all of the parameters of the first parameter, can also be used to instruct the first device to accept the modifications to some or all of the parameters of the first parameter by the intent management module of the second device.

[0210] Specifically, the relevant descriptions of the first creation request information and the first modification request information can be found in the descriptions of the first creation request information and the first modification request information in S421 above. For the sake of brevity, this application will not repeat them here.

[0211] In the above scheme, if the first device accepts all the parameter modifications in the first parameter by the intent management module of the second device, the first device can send only the second information to the second device, without needing to send at least one first creation request information and / or first modification request information to the intent management module of the second device.

[0212] It should be understood that in the above scheme, when the expression values ​​of parameters whose evaluation values ​​do not reach the expression values ​​are the same within the first parameter, a new request message can be sent; when the expression values ​​of parameters whose evaluation values ​​do not reach the expression values ​​are different within the first parameter, more than one new request message can be sent.

[0213] It should also be understood that, unless otherwise specified, there are no restrictions on the order of the steps in the above scheme, nor are there any restrictions on the causal relationship or other logical relationship between them, and some steps are optional. This application does not limit the implementation method.

[0214] Based on the above scheme, by adding information elements to the intent translation information and intent execution notification information, the parameters that the second device needs to feedback can be indicated; by adding information elements to the intent context update information, the achievement status of the calculated parameters that need to be fed back can be indicated; the intent management module of the second device can modify the expression of the intent parameters according to the obtained intent achievement details, and return feedback information to the first device, sending the modified expression of the intent parameters and the intent achievement details to the first device.

[0215] Furthermore, the first device receives first information from the intent management module of the second device. If the evaluation value of the first parameter does not reach the expression value of the first parameter, the first device sends second information to the intent management module of the second device. Thus, the first device can manage the intent based on the evaluation value and expression value of the first parameter of the first intent, as well as the modification instruction information. For example, it can send information to the intent management module of the second device to make the evaluation value of the first parameter reach the expression value of the first parameter, so that the first device can purposefully adjust the expression value of the intent parameter to satisfy the intent. This avoids the situation where the first device cannot know the specific circumstances of the intent not being satisfied, resulting in an inappropriate adjustment of the expression value of the intent parameter. In addition, the first device can send information to the intent management module of the second device to instruct the second device to provide feedback on the parameters that the second device needs to provide feedback on. This avoids the situation where the first device can only operate on the various fields of the intent based on guesswork, resulting in a large number of negotiation times with the second device, saving system maintenance resources and improving system performance.
