[0002] A network slice service can carry the requirements of a certain industry customer for network capabilities, that is, the slice service demand information (such as latency, rate, etc.). At present, the deployment process of the network slice service may include: after the operator's network management system (NMS) receives the service demand information of the network slice service from the industry user, it decomposes it into core network (CN) service demand information and radio access network (RAN) service demand information, and sends the CN service demand information to the CN domain management function unit, and sends the RAN service demand information to the RAN domain management function unit; the CN domain management function unit deploys the CN service of the above network slice service according to the CN service demand information and configures the CN service information to the network slice selection function (NSSF); the RAN domain management function unit determines the wireless resource information of each base station for the above network slice service according to the RAN service demand information, and configures it to the corresponding base station, and the corresponding wireless resources are reserved for the above industry users until the above network slice service is deleted.

[0003] According to the above-mentioned deployment process of network slicing services, it may cause waste of wireless resources and core network resources. Untimely deployment may cause unavailability of network slicing services. Summary of the invention

[0004] The embodiments of the present application provide a network slicing service deployment method and a communication device, which can deploy network slicing services in a timely manner and help reduce waste of resources.

[0005] In a first aspect, an embodiment of the present application provides a network slicing service deployment method, which can be executed by a first device, or by a device matching the first device, such as a processor, a chip, or a chip system. The first device can be, for example, a cross-domain management functional unit. The method may include: receiving a first message of a network slicing service, the first message including service usage time and service demand information, and the network slicing service needs to meet the service usage time and service demand information; allocating a service identifier based on the first message, and obtaining core network service demand information and access network service demand information according to the service demand information; sending a second message to a second device, the second message including a service identifier, service usage time and access network service demand information, the network slicing service includes an access network service, and the access network service needs to meet the service usage time and access network service demand information; sending a third message to a third device, the second message including a service identifier, service usage time and core network service demand information, the network slicing service also includes a core network service, and the core network service needs to meet the service usage time and core network service demand information.

[0006] The service usage time is used to describe the time when the network slice service is used, such as the time when the network slice service can be used, or the time when the network slice service is requested to be used. The service demand information is used to describe the performance requirements or indicator requirements of the network slice service, such as requiring the delay of the network slice service to be within a certain range, the rate of the network slice service to be within a certain range, etc. The second device may be, for example, an access domain management functional unit, and the third device may be, for example, a core domain management functional unit.

[0007] By implementing the method provided in the first aspect, the network slicing service is decomposed into the access network service and the core network service. Both the access network service and the core network service must meet the service usage time, so that the network slicing service can be deployed in time, which helps to reduce the waste of resources. The access network service meets the service usage time, which can reduce the waste of wireless resources; the core network service meets the service usage time, which can reduce the waste of core network resources.

[0008] In a possible implementation, the second message may further include configuration indication information for indicating whether the second device should immediately send the wireless resource allocation policy for the access network service to the network device upon receiving the second message. Thus, the second device may determine, based on the configuration indication information, whether to immediately send the wireless resource allocation policy for the access network service to the network device upon receiving the second message, so as to reduce the waste of wireless resources.

[0009] Optionally, the configuration indication information indicates a first value, specifically indicating that the second device, upon receiving the second message, immediately sends the wireless resource allocation policy for the access network service to the network device. That is, upon receiving the second message, the second device immediately determines the wireless resource allocation policy for the access network service and sends it to the network device. The configuration indication information indicates a second value, specifically indicating that the second device, upon receiving the second message, does not immediately send the wireless resource allocation policy for the access network service to the network device. That is, upon receiving the second message, the second device does not immediately send the wireless resource allocation policy to the network device, but sends the wireless resource allocation policy to the network device after a period of time. The period of time is before the expiration of the service usage time.

[0010] In a possible implementation, the second message may further include first deletion indication information, which is used to indicate whether the second device deletes the access network service after the service usage time expires. If the second device is instructed to delete the access network service after the service usage time expires, the access network service can be deployed and used in a timely manner and deleted upon expiration. Optionally, when deleting the access network service, wireless resources may be released by default to reduce waste of wireless resources. Optionally, the first deletion indication information is used to indicate whether the second device deletes the access network service and releases resources after the service usage time expires to reduce waste of wireless resources.

[0011] In a possible implementation, the third message may further include second deletion indication information, which is used to indicate whether the third device deletes the core network service after the service usage time expires. If the third device is instructed to delete the core network service after the service usage time expires, the core network service can be deployed and used in a timely manner and deleted upon expiration. Optionally, when deleting the core network service, the core network resources (for example, releasing the core network network elements, etc.) may be released by default to reduce the waste of core network resources. Optionally, the second deletion indication information is used to indicate whether the third device deletes the core network service and releases the core network resources after the service usage time expires to reduce the waste of core network resources.

[0012] In a possible implementation, the service usage time includes a start time and an end time, the start time is the time when the network slice service starts to be used, and the end time is the time when the network slice service ends to be used. Optionally, the service usage time includes at least one time window, each time window includes a start time and an end time, so as to further reduce the waste of resources.

[0013] In a second aspect, an embodiment of the present application provides a network slicing service deployment method, which can be executed by a second device, or by a device matching the second device, such as a processor, a chip, or a chip system. The second device can be, for example, an access network domain management functional unit. The method may include: receiving a second message from a first device, the second message including a service identifier of a network slicing service, a service usage time of a network slicing service, and access network service demand information, the network slicing service including an access network service, and the access network service needs to meet the service usage time and access network service demand information; based on the service usage time and access network service demand information, determining a wireless resource allocation strategy and a policy effective time for the access network service; the policy effective time is the same as the service usage time.

[0014] Among them, the service usage time is used to describe the time when the network slice service is used, such as the time when the network slice service can be used, or the time when the network slice service is requested. The policy effective time is the same as the service usage time, that is, the wireless resource allocation policy is used for access network services during the policy effective time. The access network service demand information is used to describe the performance requirements or indicator requirements of the access network service, such as the delay of the access network service is required to be within a certain range, the rate of the access network service is required to be within a certain range, etc.

[0015] Implementing the method provided in the second aspect, the second device determines the wireless resource allocation strategy and the policy effective time based on the service usage time and the access network service demand information, so that the access network service can meet the service usage time and the access network service demand information, thereby timely deploying the access network service and reducing the waste of wireless resources.

[0016] In a possible implementation, the second message may further include configuration indication information for indicating whether the second device should immediately send the wireless resource allocation policy for the access network service to the network device upon receiving the second message. Thus, the second device may determine, based on the configuration indication information, whether to immediately send the wireless resource allocation policy for the access network service to the network device upon receiving the second message, so as to reduce the waste of wireless resources.

[0017] Optionally, the configuration indication information indicates a first value, specifically indicating that the second device, upon receiving the second message, immediately sends the wireless resource allocation policy for the access network service to the network device. That is, upon receiving the second message, the second device immediately determines the wireless resource allocation policy for the access network service and sends it to the network device. The configuration indication information indicates a second value, specifically indicating that the second device, upon receiving the second message, does not immediately send the wireless resource allocation policy for the access network service to the network device. That is, upon receiving the second message, the second device does not immediately send the wireless resource allocation policy to the network device, but sends the wireless resource allocation policy to the network device after a period of time. The period of time is before the expiration of the service usage time.

[0018] In one possible implementation, in response to the configuration indication information indicating a first value, upon receiving the second message, the wireless resource allocation strategy and the policy effective time are immediately sent to the network device, so that the network device can timely allocate wireless resources to the terminal device based on the wireless resource allocation strategy and the policy effective time, so that the access network service can be deployed and used in time. In response to the configuration indication information indicating a second value, the wireless resource allocation strategy and the policy effective time are sent to the network device within a first time, the first time is earlier than the policy effective time and later than the reception time of the second message, and the time difference between the first time and the policy effective time is less than the preset time difference. For example, after receiving the second message, the wireless resource allocation strategy and the policy effective time are sent to the network device within 1 hour before the policy effective time. The second device does not immediately send the wireless resource allocation strategy and the policy effective time to the network device, which can reduce the waste of wireless resources.

[0019] In a possible implementation, the second message may further include first deletion indication information, which is used to indicate whether the second device deletes the access network service after the service usage time expires. If the second device is instructed to delete the access network service after the service usage time expires, the access network service can be deployed and used in a timely manner and deleted upon expiration. Optionally, when deleting the access network service, wireless resources may be released by default to reduce waste of wireless resources. Optionally, the first deletion indication information is used to indicate whether the second device deletes the access network service and releases resources after the service usage time expires to reduce waste of wireless resources.

[0020] In a possible implementation, the first deletion indication information indicates a third value, that is, instructs the second device to delete the access network service after the service usage time expires. Then, when the first deletion indication information indicates the third value and the current time exceeds the service usage time, the second device deletes the service information of the access network service to delete the access network service; and sends a first deletion request to the network device, the first deletion request is used to request the network device to delete the wireless resource allocation policy to reduce the waste of wireless resources. The service information of the access network service includes a service identifier to completely delete the access network service.

[0021] In a possible implementation, the service usage time includes a start time and an end time, the start time is the time when the network slice service starts to be used, and the end time is the time when the network slice service ends to be used.

The third device can be, for example, a core network domain management functional unit. The method may include: receiving a third message from the first device, the third message including a service identifier of the network slicing service, a service usage time of the network slicing service, and core network service demand information, the network slicing service includes a core network service, and the core network service needs to meet the service usage time and core network service demand information; based on the service usage time and core network service demand information, determining the service configuration information of the core network service; sending the service configuration information and service usage time of the core network service to the core network network element.

[0023] The service usage time is used to describe the time when the network slice service is used, such as the time when the network slice service can be used or the time when the network slice service is requested. The core network service demand information is used to describe the performance requirements or indicator requirements of the core network service, such as the delay range of the core network service and the rate range of the core network service.

[0024] Implementing the method provided by the third aspect, the third device determines the service configuration information of the core network service based on the service usage time and the core network service demand information, and sends it and the service usage time to the core network network element, so that the core network network element can provide core network services that meet the service usage time and service configuration information, thereby timely deploying core network services and reducing the waste of core network resources.

[0025] In a possible implementation, the third message also includes second deletion indication information, which is used to indicate whether the third device deletes the core network service after the service usage time expires. If the third device is instructed to delete the core network service after the service usage time expires, the core network service can be deployed and used in a timely manner and deleted upon expiration. Optionally, when deleting the core network service, the core network resources can be released by default to reduce the waste of core network resources. Optionally, the second deletion indication information is used to indicate whether the third device deletes the core network service and releases the core network resources after the service usage time expires to reduce the waste of core network resources.

[0026] In one possible implementation, the second deletion indication information indicates a fourth value, that is, instructs the third device to delete the core network service after the service usage time expires. Then, when the second deletion indication information indicates the fourth value and the current time exceeds the service usage time, the service information of the core network service is deleted to delete the core network service; and a second deletion request is sent to the core network network element, and the second deletion request is used to request the core network network element to delete the service configuration information and service identification of the core network service to reduce the waste of core network resources. Among them, the service information of the core network service includes the service identification to completely delete the core network service. After the core network network element deletes the service configuration information and service identification of the core network service, the core network network element no longer supports the core network service, and no longer supports the above-mentioned network slicing service.

[0062] In the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previously associated objects are in an "or" relationship.

[0063] It should be understood that in this application, "at least one" means one or more; "plurality" means two or more. In addition, "equal to" in this application can be used in conjunction with "greater than" or "less than". When "equal to" is used in conjunction with "greater than", the technical solution of "greater than" is adopted; when "equal to" is used in conjunction with "less than", the technical solution of "less than" is adopted.

[0064] In the present application, "sending information to... (e.g., a terminal device)" can be understood as the destination of the information being the terminal device. This can include sending information to the terminal device directly or indirectly. "Receiving information from... (e.g., a terminal device)" or "receiving information from... (e.g., a terminal device)" can be understood as the source of the information being the terminal device, which can include receiving information from the terminal device directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly and will not be repeated here.

[0065] The following is an explanation of the relevant names or terms involved in this application to facilitate understanding by those skilled in the art.

[0066] 1. Terminal equipment

[0067] Terminal equipment can also be called user equipment (UE), mobile station (MS), mobile terminal (MT), etc., or equipment used to provide voice or data connectivity to users, or IoT devices. For example, terminal equipment includes handheld devices with wireless connection functions, vehicle-mounted devices, etc. At present, terminal devices can be: mobile phones, tablet computers, laptops, PDAs, mobile internet devices (MID), wearable devices (such as smart watches, smart bracelets, pedometers, etc.), vehicle-mounted devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, smart point of sale (POS) machines, customer-premises equipment (CPE), wireless terminals in industrial control, smart home devices (such as refrigerators, TVs, air conditioners, electric meters, etc.), smart robots, robotic arms, workshop equipment, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, flight equipment (such as smart robots, hot air balloons, drones, airplanes), etc. The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device that serves as a terminal function in D2D communication.

[0068] 2. Network equipment

[0069] The network device is a node in the RAN, which can also be called an access network device, or a RAN node (or device). The network device is used to help terminal devices achieve wireless access. In one possible scenario, the network device can be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next generation NodeB (gNB), a next generation base station in a 6G system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, an access network device in a mobile switching center non-terrestrial network (NTN) communication system, that is, it can be deployed on a high altitude platform or satellite, etc. The network device can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a wireless controller in a cloud radio access network (CRAN) scenario. The network device may also be a device that acts as a base station in device-to-device (D2D) communication, Internet of Vehicles communication, drone communication, and machine communication. Optionally, the network device may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0070] All or part of the functions of the network device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform).

[0071] In another possible scenario, multiple network devices collaborate to assist the terminal in achieving wireless access, and different network devices respectively implement part of the functions of the base station. For example, the network device may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be set separately, or may be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understandable that the network device may be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into a network device in the access network RAN, or the CU may be divided into a network device in the core network CN, without limitation here.

[0072] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open access network (open RAN, O-RAN or ORAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0074] In order to realize functions such as model training, business design, and business orchestration, autonomous networks came into being. Autonomous networks automatically control the network through automation / intelligent technology. Autonomous networks can manage, analyze, and control the network to achieve single-domain autonomy and cross-domain collaboration.

[0075] For example, the network structure of the autonomous network can be found in Figure 1 shown. Figure 1 The autonomous network shown may be at least one of the following networks:

[0076] Single-domain autonomous network: includes network elements and domain management functional units;

[0077] Cross-domain autonomous network: including network elements, domain management functional units and cross-domain management functional units;

[0078] Business autonomous network: includes network elements, domain management functional units, cross-domain management functional units and business operation units.

[0079] The business operation unit, also known as the communication service management function unit, can provide functions and management services such as billing, settlement, accounting, customer service, business, network monitoring, communication service life cycle management, and business intent translation. The business operation unit includes the operator's operation system or the operation system of a vertical industry.

[0080] The cross-domain management function unit, which may also be referred to as a network management function unit (network management function, NMF), may provide one or more of the following management functions or management services: network lifecycle management, network deployment, network fault management, network performance management, network configuration management, network assurance, network optimization function, translation of intent from communication service provider (intent-CSP) (or simply business intent), translation of intent from communication service consumer (intent-CSC) (or simply business intent), etc. Among them, the network may include at least one network element, at least one subnetwork, or at least one network slice. For example, the cross-domain management function unit may be a network slice management function (network slice management function, NSMF), a management data analytical function (management data analytical function, MDAF), a cross-domain self-organization network function (self-organization network function, SON-function), or a cross-domain intent management function unit.

[0081] In some deployment scenarios, the cross-domain management functional unit may also provide one or more of the following management functions or management services: sub-network lifecycle management, sub-network deployment, sub-network fault management, sub-network performance management, sub-network configuration management, sub-network assurance, sub-network optimization function, communication service provider's sub-network intention translation, communication service user's sub-network intention translation, etc. Among them, the sub-network may be composed of multiple small sub-networks or multiple network slice sub-networks.

[0082] The domain management function unit may also be referred to as a subnetwork management function (NMF) or a network element / function management function unit. The domain management function unit may provide one or more of the following management functions or management services: lifecycle management of subnetworks or network elements, deployment of subnetworks or network elements, fault management of subnetworks or network elements, performance management of subnetworks or network elements, assurance of subnetworks or network elements, optimization management of subnetworks or network elements, intent translation of subnetworks or network elements, etc. Among them, a subnetwork includes one or more network elements. Alternatively, a subnetwork may also include one or more subnetworks, that is, one or more subnetworks form a subnetwork with a larger coverage area. Alternatively, a subnetwork may also include one or more network slice subnetworks. A subnetwork includes one of the following descriptions:

[0083] A network in a certain technical domain, such as a wireless access network, core network, or transport network;

[0084] A certain type of network, such as 5G network, 6G network, etc.

[0085] A network provided by a certain equipment vendor, such as the network provided by equipment vendor X;

[0086] A network in a certain geographical area, such as the network of factory A, the network of prefecture-level city B, etc.

[0087] Network elements are entities that provide network services, including core network elements, access network elements, etc. For example, core network elements may include but are not limited to access and mobility management function (AMF) entity, session management function (SMF) entity, policy control function (PCF) entity, network data analysis function (NWDAF) entity, network repository function (NRF), gateway, NSSF entity, etc. Access network elements may be the above-mentioned network devices.

[0088] In the service-oriented management architecture, it can include management service providers (Management Service Producer, MnS Producer) and management service consumers (Management Service Consumer, MnS Consumer). It can be understood that:

[0089] When the management service is a management service provided by the above-mentioned business operation unit, the business operation unit is the management service provider, and other business operator units may be management service consumers;

[0090] When the management service is the management service provided by the above-mentioned cross-domain management function unit, the cross-domain management function unit is the management service provider and the business operation unit is the management service consumer;

[0091] When the management service is a management service provided by the above-mentioned domain management functional unit, the domain management functional unit is the management service provider, and the cross-domain management functional unit or the business operation unit is the management service consumer;

[0092] When the management service is a management service provided by the above network element, the network element is the management service provider, and the domain management function unit, the cross-domain management function unit or the business operation unit is the management service consumer.

[0093] See also Figure 2 , is a flow chart of a network slicing service deployment method. The method may include the following steps:

[0094] 1. The industry user sends a slice service request to the NMS. Correspondingly, the NMS receives the slice service request from the industry user.

[0095] Among them, the slice service request includes service demand information, that is, the service demand information of the network slice service. The slice service request is used to request a network slice service that needs to meet the service demand information. In other words, the slice service request is used to request a network slice service that meets the service demand information.

[0096] In response to the received slice service request, the NMS decomposes the service requirement information into RAN service requirement information and CN service requirement information.

[0097] 2a, the NMS sends a RAN slicing service request to the RAN domain management function unit. Correspondingly, the RAN domain management function unit receives the RAN slicing service request from the NMS.

[0098] Among them, the RAN slice service request may include RAN service requirement information.

[0099] 2b, NMS sends a CN slice service request to the CN domain management function unit. Correspondingly, the CN domain management function unit receives the CN slice service request from NMS.

[0100] Among them, the CN slice service request may include CN service demand information.

[0101] Step 2a and step 2b can be understood as NMS sending RAN service demand information to RAN domain management function unit and sending CN service demand information to CN domain management function unit. Both can be performed at the same time, or step 2a can be performed first and then step 2b, or step 2b can be performed first and then step 2a.

[0102] 3a, the RAN domain management function unit sends the radio resource information to the network device. Correspondingly, the network device receives the radio resource information from the RAN domain management function unit.

[0103] The radio resource information includes radio resource management (RRM) policy.

[0104] The RAN domain management functional unit responds to the received RAN slice service request, determines the wireless resource information of each network device for the above network slice service according to the RAN service demand information, and configures it to the corresponding network device. The corresponding wireless resources are reserved for the above industry users until the above network slice service is deleted.

[0105] 3b, the CN domain management function unit sends service information to the NSSF. Correspondingly, the NSSF receives the service information from the CN domain management function unit.

[0106] Among them, the business information may include network slice selection assistance information, such as single network slice selection assistance information (single network slice selection assistance information, S-NSSAI) and the like.

[0107] The CN domain management functional unit responds to the received CN slicing service request, deploys the CN service of the above-mentioned network slicing service according to the CN service demand information, and configures the service information of the CN service on the NSSF.

[0108] Figure 2 The network slicing service deployment method shown is a deployment-and-activation method, that is, when the network slicing service is deployed, the corresponding configuration parameters are issued and take effect, and the corresponding wireless resources are reserved, which may cause the following problems:

[0109] If network slicing services are deployed in advance, wireless resources will be wasted because the corresponding wireless resources have been allocated before the network slices are used;

[0110] If the network slicing service is deployed only when it is used, the network slicing service will not be deployed in time or the network slicing service deployment will fail, resulting in unavailability for industry users, because the deployment of network slicing services takes a long time, generally three days;

[0111] When there are a large number of network slice services, the accuracy of the network slice service pre-assessment results may be low. For example, it may be pre-assessed that there are no available resources, but in fact there are available resources.

[0112] When industry users do not use the network slicing service, the corresponding wireless resources will still be reserved for the network slicing service or the operator will still operate the network slicing service, resulting in a waste of wireless resources or human resources.

[0113] Given that Figure 2 The network slicing service deployment method shown has the above-mentioned problems. The embodiment of the present application provides a network slicing service deployment method, which can deploy network slicing services in a timely manner and help reduce waste of resources.

[0114] Before describing the network slicing service deployment method provided in the embodiment of the present application, the network architecture to which the embodiment of the present application is applied is described. For the convenience of description, the core network is referred to as CN and the access network is referred to as RAN.

[0115] See also Figure 3 , is a schematic diagram of a network architecture applying an embodiment of the present application. Figure 3 The network architecture shown includes a management device, a first device, a second device, a third device, a network device and a core network element.

[0116] Among them, the management device refers to the equipment of industry users, which can be a business operation unit, such as an operator's operation system or a vertical industry's operation system. The first device can be the above-mentioned cross-domain management functional unit. In the embodiment of the present application, it can be an operator management device. The second device can be the above-mentioned RAN domain management functional unit. In the embodiment of the present application, it can be an equipment vendor management device, specifically a RAN equipment vendor management device. The third device can be the above-mentioned CN domain management functional unit. In the embodiment of the present application, it can be an equipment vendor management device, specifically a CN equipment vendor management device. The core network network element can be the above-mentioned NSSF and / or NWDAF.

[0117] The interface between the management device and the first device can be called a business management service interface, the interface between the first device and the second device can be called a RAN subnetwork management service interface, the interface between the first device and the second device can be called a CN subnetwork management service interface, and the interface between the second device and the network device can be called a base station configuration service interface; the interface between the third device and the core network element can be called a core network element service interface.

[0118] In the embodiment of the present application, the management device may send a network slicing service request to the first device, for requesting the first device to provide a network slicing service that meets the request; the first device may send a RAN service request to the second device, for requesting the second device to provide a RAN service that meets the request, and the second device may send an RRMpolicy to the network device in response to the request; the first device may send a CN service request to the third device, for requesting the third device to provide a CN service that meets the request, and the third device may send service configuration information of the CN service to the core network element in response to the request. The above-mentioned RAN service and the above-mentioned CN service may constitute the above-mentioned network slicing service.

[0119] The above requests include service usage time to request network slicing services that meet the service usage time. Correspondingly, when the second network element sends RRMpolicy to the network device, it also sends the service usage time, so that the RAN service is used within the service usage time and is not used outside the service usage time, so as to reduce the waste of wireless resources. When the third network element sends service configuration information to the core network network element, it also sends the service usage time, so that the CN service is valid within the service usage time and is not invalid outside the service usage time, so as to reduce the waste of core network resources.

[0120] The following is based on Figure 3 The network architecture shown in the figure illustrates the network slicing service deployment method provided in the embodiment of the present application. For the convenience of description, the terminal device takes UE as an example.

[0121] See also Figure 4 , is a flow chart of a network slicing service deployment method provided in an embodiment of the present application. The method may include but is not limited to the following steps:

[0122] 401, the management device sends a first message to the first apparatus. Correspondingly, the first apparatus receives the first message from the management device. The first message includes service usage time and service demand information.

[0123] The first message may be a network slicing service request, or a network slicing service management request, etc., which is used to request the first device to provide a network slicing service that meets the service usage time and service demand information. In other words, the network slicing service needs to meet the service usage time and service demand information. The network slicing service may also be referred to as the network service. The embodiment of the present application takes the first message used to request network slicing service 1 as an example.

[0124] Among them, the service demand information is used to describe the performance requirements or indicator requirements of network slice service 1. Performance may include one or more of the following: latency, UE throughput, maximum number of UEs, reliability, availability, etc. The service demand information, for example, requires that the latency of network slice service 1 be within a certain range, the user rate of network slice service 1 be within a certain range, etc.

[0125] The service usage time is used to describe the time when the management device of the industry user uses the network slice service 1, such as the time when the network slice service 1 can be used, or the time when the network slice 1 is requested to be used. The service usage time can be a time window, and the time window can include a start time (StartTime) and an end time (EndTime). The start time is the time to start using the network slice service 1, that is, the time when the management device of the industry user can start using the network slice service 1; the end time is the time to end using the network slice service, that is, the time when the management device of the industry user cannot use the network slice service 1. In other words, once the system time exceeds the end time, the management device of the industry user can no longer use the network slice service 1.

[0126] Optionally, the service usage time may include at least one time window, each time window including a start time and an end time, so as to flexibly use the network slice service 1, which can further reduce the waste of resources.

[0127] Carrying the service usage time in the first message enables the first device to obtain the accurate service usage time of the industry user for a specific network slice service, and then to arrange and reserve resources for the network slice service in advance.

[0128] In response to the received first message, the first device allocates a service identifier for network slice service 1, where the service identifier is used to identify the network slice service 1 requested by the first message. The service identifier may be S-NSSAI, and in the embodiment of the present application, the service identifier is exemplified by S-NSSAI A.

[0129] The first device also obtains RAN service demand information and CN service demand information according to the service demand information in response to the received first message. It can be understood that the first device decomposes the service demand information into RAN service demand information and CN service demand information. The RAN service demand information is used to describe the performance requirements of the RAN service in the network slice service 1, and the CN service demand information is used to describe the performance requirements of the CN service in the network slice service 1. Among them, the performance may include one or more of the following: latency, user rate (UE throughput), number of users (maximum number of UE), reliability (reliability), availability (availability), etc. In the embodiment of the present application, the RAN service of the network slice service 1 takes RAN service 2 as an example, and the CN service takes CN service 3 as an example. The network slice service 1 includes RAN service 2 and CN service 3.

[0130] Exemplarily, the service demand information is decomposed into RAN service demand information and CN service demand information, which may be: when the service demand information includes a delay less than 10 milliseconds (ms), the CN service demand information may include a delay less than 3ms, and the RAN service demand information may include a delay less than 7ms; when the service demand information includes a number of users greater than 500, the CN service demand information may include a number of users greater than 500, and the RAN service demand information may include a number of users greater than 500.

[0131] 402a, the first device sends a second message to the second device. Correspondingly, the second device receives the second message from the first device. The second message includes a service identifier, service usage time, and RAN service requirement information. That is, the second message includes S-NSSAI A, service usage time, and RAN service requirement information.

[0132] The second message may be a RAN service request for requesting the second device to provide a RAN service that meets the service usage time and the RAN service requirement information. That is, the second message is used to request the second device to provide a RAN service 2 that meets the service usage time and the RAN service requirement information.

[0133] 402b, the first device sends a third message to the third device. Correspondingly, the third device receives the third message from the first device. The third message includes a service identifier, service usage time, and CN service requirement information. That is, the third message includes S-NSSAI A, service usage time, and CN service requirement information.

[0134] The third message may be a CN service request for requesting the third device to provide a CN service that meets the service usage time and CN service requirement information. That is, the second message is used to request the second device to provide a CN service 3 that meets the service usage time and CN service requirement information.

[0135] Step 402a and step 402b can be understood as the first device sending the RAN service demand information and service usage time to the second device, and sending the CN service demand information and service usage time to the third device. Both can be performed at the same time, or step 402a is performed first and then step 402b, or step 402b is performed first and then step 402a.

[0136] 403a, the second device sends the wireless resource allocation policy and the policy effective time to the network device. Correspondingly, the network device receives the wireless resource allocation policy and the policy effective time from the second device.

[0137] The radio resource allocation policy is the above RRM policy. The radio resource allocation policy has a policy effective time, that is, the radio resource allocation policy is not always effective, but is effective within the policy effective time.

[0138] In response to the received second message, the second device determines the wireless resource allocation strategy and the policy effective time based on the service usage time and the RAN service demand information, and sends the wireless resource allocation strategy and the policy effective time to the network device. The policy effective time is the same as the service usage time. That is, the wireless resource allocation strategy is valid during the service usage time.

[0139] The network device may configure radio resources for the UE based on the radio resource allocation policy and the policy effective time, and indicate the configured radio resources to the UE.

[0140] 403b, the third device sends the service configuration information and service usage time of the CN service to the core network element. Correspondingly, the core network element receives the service configuration information and service usage time from the third device.

[0141] The service configuration information of the CN service may include but is not limited to a service identifier, a public land mobile network (PLMN) identifier, service coverage area information, etc. The service usage time of the network slice service 1 is also the service usage time of the CN service 2.

[0142] In response to the received third message, the third device determines the service configuration information and service usage time of the CN service based on the service usage time and the CN service demand information, so as to send the service configuration information and service usage time of the CN service to the core network network element.

[0143] The embodiment of the present application does not limit the order in which step 403a and step 403b are executed. They may be executed simultaneously, or step 403a may be executed first and then step 403b, or step 403b may be executed first and then step 403a.

[0144] For RAN service 2 and CN service 3, their service identifiers can both be the service identifier of network slicing service 1, that is, S-NSSAIA.

[0145] contrast Figure 4 and Figure 2 It can be seen that Figure 4 Increasing service usage time enables the operator management system to arrange resources on demand based on the actual time requirements of the service, ensuring that network slicing services are provided according to actual needs while reducing resource waste.

[0146] Figure 4 based on Figure 3 The network architecture shown in FIG. 1 partially illustrates the network slicing service deployment method provided in the embodiment of the present application. Figure 5 The network slice deployment method provided in the embodiment of the present application will be described in detail. It can be understood that Figure 5 The embodiment shown is for Figure 4 Further description of the illustrated embodiment.

[0147] See also Figure 5 , is a flow chart of another network slicing service deployment method provided in an embodiment of the present application. The method may include but is not limited to the following steps:

[0148] 501, the management device sends a first message to the first apparatus. Correspondingly, the first apparatus receives the first message from the management device. The first message includes service usage time and service demand information.

[0149] Step 501 can be found in Figure 4 The specific description of step 401 in the illustrated embodiment will not be repeated here.

[0150] 502. The first device allocates a service identifier based on the first message, and obtains RAN service requirement information and CN service requirement information according to the service requirement information.

[0151] In response to the received first message, the first device allocates a service identifier for network slice service 1, where the service identifier is used to identify the network slice service 1 requested by the first message. The service identifier may be S-NSSAI, and in the embodiment of the present application, the service identifier is exemplified by S-NSSAI A.

[0152] The first device also obtains RAN service demand information and CN service demand information according to the service demand information in response to the received first message. It can be understood that the first device decomposes the service demand information into RAN service demand information and CN service demand information. The RAN service demand information is used to describe the performance requirements of the RAN service in the network slice service 1, and the CN service demand information is used to describe the performance requirements of the CN service in the network slice service 1. Among them, the performance may include one or more of the following: latency, user rate (UE throughput), number of users (maximum number of UE), reliability (reliability), availability (availability), etc. In the embodiment of the present application, the RAN service of the network slice service 1 takes RAN service 2 as an example, and the CN service takes CN service 3 as an example. The network slice service 1 includes RAN service 2 and CN service 3.

[0153] Exemplarily, the service demand information is decomposed into RAN service demand information and CN service demand information, which may be: when the service demand information includes a delay less than 10 milliseconds (ms), the CN service demand information may include a delay less than 3ms, and the RAN service demand information may include a delay less than 7ms; when the service demand information includes a number of users greater than 500, the CN service demand information may include a number of users greater than 500, and the RAN service demand information may include a number of users greater than 500.

[0154] 503, the first device sends a second message to the second device. Correspondingly, the second device receives the second message from the first device. The second message includes the service identifier, service usage time and RAN service requirement information. That is, the second message includes S-NSSAI A, service usage time and RAN service requirement information. Step 503 is Figure 4 Step 402a in .

[0155] The second message may be a RAN service request for requesting the second device to provide a RAN service that meets the service usage time and the RAN service requirement information. That is, the second message is used to request the second device to provide a RAN service 2 that meets the service usage time and the RAN service requirement information.

[0156] Optionally, the second message may further include configuration indication information for indicating whether the second device should immediately send the radio resource allocation policy of the RAN service to the network device upon receiving the second message. Thus, the second device may determine, based on the configuration indication information, whether to immediately send the radio resource allocation policy of the RAN service to the network device upon receiving the second message, so as to reduce waste of radio resources.

[0157] Exemplarily, the configuration indication information indicates a first value, specifically indicating that the second device immediately sends a wireless resource allocation policy to the network device upon receiving the second message. That is, upon receiving the second message, the second device immediately determines the wireless resource allocation policy and sends it to the network device. Immediately can be understood as a short time interval between receiving the second message and sending the wireless resource allocation policy. The configuration indication information indicates a second value, specifically indicating that the second device does not immediately send the wireless resource allocation policy to the network device upon receiving the second message. That is, upon receiving the second message, the second device does not immediately send the wireless resource allocation policy to the network device, but sends the wireless resource allocation policy to the network device after a period of time. The period of time is before the expiration of the service usage time. It should be noted that when the second device sends the wireless resource allocation policy to the network device, it also sends the policy effective time.

[0158] It can be understood that the configuration indication information can be a field in the second message. When the value of this field is a first value (for example, "1"), it indicates that the second device immediately sends the wireless resource allocation policy to the network device when receiving the second message; when the value of this field is a second value (for example, "0"), it indicates that the second device does not immediately send the wireless resource allocation policy to the network device when receiving the second message.

[0159] Optionally, the second message may further include first deletion indication information, which is used to indicate whether the second device deletes the RAN service after the service usage time expires. If the second device is instructed to delete the RAN service after the service usage time expires, the RAN service can be deployed and used in a timely manner and deleted upon expiration. Optionally, when deleting the access network service, the wireless resources may be released by default to reduce the waste of wireless resources. Optionally, the first deletion indication information is used to indicate whether the second device deletes the access network service and releases the resources after the service usage time expires to reduce the waste of wireless resources.

[0160] Exemplarily, the first deletion indication information indicates a third value, specifically instructing the second device to delete the RAN service after the service usage time expires. It can be understood that the first deletion indication information can be a field in the second message, and when the value of the field is a third value (e.g., "1"), it instructs the second device to delete the RAN service after the service usage time expires.

[0161] 504. The second device determines a wireless resource allocation strategy and a strategy effective time based on the service usage time and the RAN service demand information.

[0162] Among them, the wireless resource allocation strategy may include but is not limited to service identification, resource type (including physical resource block (PRB), data radio bearer (DRB) and radio resource control (RRC) resources, etc.) and resource usage ratio (including dedicated resource ratio, minimum resource usage ratio and maximum resource usage ratio, etc.).

[0163] The wireless resource allocation policy has a policy effective time, that is, the wireless resource allocation policy is not always effective, but is effective within the policy effective time.

[0164] In response to the received second message, the second device determines the wireless resource allocation strategy and the policy effective time based on the service usage time and the RAN service demand information, and sends the wireless resource allocation strategy and the policy effective time to the network device. The policy effective time is the same as the service usage time. That is, the wireless resource allocation strategy is valid during the service usage time.

[0165] 505, the second device sends the wireless resource allocation policy and the policy effective time to the network device. Correspondingly, the network device receives the wireless resource allocation policy and the policy effective time from the second device. Step 505 is Figure 4 Step 403a in .

[0166] For the second message including configuration indication information, the configuration indication information indicates a first value, and when the second device receives the second message, it immediately determines the wireless resource allocation strategy and the policy effective time, and sends the wireless resource allocation strategy and the policy effective time to the network device, so that the network device can timely allocate wireless resources to the terminal device based on the wireless resource allocation strategy and the policy effective time, so that the RAN service can be deployed and used in time. The configuration indication information indicates a second value, and the second device sends the wireless resource allocation strategy and the policy effective time to the network device within a first time, the first time is earlier than the policy effective time and later than the reception time of the second message, and the time difference between the first time and the policy effective time is less than the preset time difference, which can be configured in advance by the operator. For example, after receiving the second message, the second device sends the wireless resource allocation strategy and the policy effective time to the network device within 1 hour before the policy effective time. The second device does not immediately send the wireless resource allocation strategy and the policy effective time to the network device, which can reduce the waste of wireless resources.

[0167] It can be understood that, for the configuration indication information indicating the second value, the second device determines that the current time (ie, the current system time) is within the specified advance time period of the policy effective time, and sends the wireless resource allocation policy and the policy effective time to the network device.

[0168] 506, the second device sends a second response message to the first device. Correspondingly, the first device receives the second response message from the second device.

[0169] The second response message is used to respond to the second message, and may be a RAN service request response message. The second response message may include a service identifier and first indication information, and the first indication information is used to indicate that the RAN service is deployed successfully.

[0170] 507, the first device sends a third message to the third device. Correspondingly, the third device receives the third message from the first device. The third message includes the service identifier, service usage time and CN service requirement information. That is, the third message includes S-NSSAI A, service usage time and CN service requirement information. Step 507 is Figure 4 Step 402b in .

[0171] The third message may be a CN service request for requesting the third device to provide a CN service that meets the service usage time and CN service requirement information. That is, the second message is used to request the second device to provide a CN service 3 that meets the service usage time and CN service requirement information.

[0172] Optionally, the third message may further include a second deletion indication information, used to indicate whether the third device deletes the CN service after the service usage time expires. If the third device is instructed to delete the CN service after the service usage time expires, the CN service can be deployed and used in a timely manner and deleted upon expiration. Optionally, when deleting the CN service, CN resources may be released by default to reduce the waste of CN resources. Optionally, the second deletion indication information is used to indicate whether the third device deletes the CN service and releases CN resources after the service usage time expires to reduce the waste of core network resources.

[0173] Exemplarily, the second deletion indication information indicates the fourth value, specifically instructing the third device to delete the CN service after the service usage time expires. It can be understood that the second deletion indication information can be a field in the third message, and when the value of the field is the fourth value (for example, "1"), it instructs the third device to delete the CN service after the service usage time expires.

[0174] 508. The third device determines the service configuration information and service usage time of the CN service based on the service usage time and the CN service demand information.

[0175] The service configuration information may include but is not limited to a service identifier, a public land mobile network (PLMN) identifier, service coverage area information, and the like.

[0176] In response to the received third message, the third device determines the service configuration information and service usage time of the CN service based on the service usage time and the CN service demand information, so as to send the service configuration information and service usage time of the CN service to the core network network element.

If the reception time of the first access request message is within the policy effective time, the network device can determine the wireless resources allocated to the UE based on the wireless resource allocation policy. On the contrary, if the reception time of the first access request message is not within the policy effective time, the first access request message is rejected.

[0193] 603, the network device sends a first access response message to the UE. Correspondingly, the UE receives the first access response message from the network device.

[0194] The first access response message is used to respond to the first access request message.

[0195] In response to the reception time of the first access request message being within the policy effective time, a first access response message is sent to the UE, and the first access response message includes the wireless resources allocated to the UE. In other words, the first access response message carrying the wireless resources is sent by the network device when the reception time of the first access request message is within the policy effective time.

The service information includes a service identifier.

[0199] 605, the second device sends a first deletion request to the network device. Correspondingly, the network device receives the first deletion request from the second device.

[0205] 702. The core network element determines whether the UE can use the CN service based on the network slice selection auxiliary information and service usage time.

[0206] The core network element determines whether the UE can use the network slice service corresponding to the network slice selection auxiliary information based on the network slice selection auxiliary information and the service usage time, and then determines whether the UE can use the CN service of the network slice service. If the reception time of the second access request message is within the service usage time, the UE can use the network slice service and the CN service. Otherwise, the UE cannot use the network slice service and the CN service.

[0207] 703, the core network element sends a second access response message to the UE. Correspondingly, the UE receives the second access response message from the core network element.

[0208] The second access response message is used to respond to the second access request message.

[0209] In response to the reception time of the second access request message being within the service usage time, a second access response message is sent to the UE, and the second access response message includes a service identifier corresponding to the CN service. That is, the second access response message carrying the service identifier is sent by the core network element when the reception time of the second access request message is within the service usage time.

[0210] In response to the fact that the reception time of the second access request message is not within the service usage time, a second access response message is sent to the UE, and the second access response message includes a rejection indication, which is used to instruct the core network element to reject the second access response message.

[0211] 704. When the current time exceeds the service usage time, the third device deletes the CN service.

[0212] When the second deletion indication information indicates the fourth value and the current time exceeds the service usage time, the third device deletes the service information of the CN service to delete the CN service. The service information includes a service identifier.

[0213] 705, the third device sends a second deletion request to the core network element. Correspondingly, the core network element receives the second deletion request from the third device.

[0214] The second deletion request is used to request the core network element to delete the service configuration information to reduce the waste of core network resources. The second deletion request may include a service identifier, requesting the core network element to delete the service configuration information corresponding to the service identifier. The core network element deletes the service configuration information corresponding to the service identifier, and the core network element no longer supports the network slice service corresponding to the service identifier.

[0215] exist Figure 7 In the illustrated embodiment, the UE can access the CN service based on the network slice selection auxiliary information, and the third device can delete the CN service when the current time exceeds the service usage time to reduce the waste of core network resources.
