Or the SMF entity sends the session establishment request message sent by the terminal device to the UDM entity/PCF entity, and the UDM entity/PCF entity verifies the session establishment request message of the terminal device, and if the verification is passed, it responds to the SMF entity.

Step S303: After successfully verifying the session establishment request message of the terminal device, the SMF entity initiates a service request to the RAN network element according to the carried group information, service-related information, and resource requirement information, and provides resource requirement information.

Wherein, the resource requirement information includes at least one of the following information: required service rate information, time delay information, reliability information, bandwidth information, etc. The resource requirement information can be session granularity, or QoS flow granularity, or service flow granularity, etc.

The element can further feed back the actually allocated resources to the charging device entity.

Step S304-Step S305, the SMF entity sends a session establishment acceptance message to the terminal device, and provides the terminal device with resources allocated by the RAN network element.

The subscription information or authorization information includes: whether the terminal device is allowed to apply for this service on the PC5 interface, and the requirements or resource attributes allowed by the terminal device to apply for this service on the PC5 interface; for example, the maximum allowed service rate, the minimum delay requirement, etc. If the verification is passed, the UDM entity/PCF entity sends the permitted service, group information, and allocatable resource information to the terminal. If the verification fails, the UDM entity/PCF entity can reject the request or determine the allocatable resources based on the actual subscription information or authorized information.

Or, the UDM entity/PCF entity of the core network can send the service information and allocatable resource information applied by the terminal device to the AMF entity or SMF entity, and the AMF entity or SMF entity encapsulates the service information and allocatable resource information applied by the terminal device as The N2 message is sent to the RAN network element; the RAN network element sends the service information and the allocatable resource information applied by the terminal device to the terminal device through the RRC message. Alternatively, the UDM entity/PCF entity of the core network encapsulates the service information and the allocatable resource information applied by the terminal device into a transparent container, and sends it to the terminal device through a NAS message or through an N2 and RRC message. Or, the core network element sends the service information and allocable resource information applied by the terminal device to the application-related server or NCIS function server (such as AF), and the application-related server or NCIS function server (such as AF) communicates with the terminal The inter-interface message protocol is sent to the terminal device.

Optionally, the resource requirement information includes at least one of the following: required service rate information, delay information//reliability information, and bandwidth information. The granularity of the resource requirement information may be session granularity, or QoS flow granularity, or service flow granularity.

After receiving the session establishment request, the RAN network element allocates resources that can be used on the PC5 interface according to the resource request information therein; and returns a resource allocation success response message to the core network element. If the RAN network element cannot allocate the required resources, it can feed back a failure message to the core network element, or the RAN network element can allocate resources that can actually be allocated, and feed back the actual allocated resources to the core network element. The actual allocated resources can be further fed back to the charging device entity.

Step S408-Step S409, the SMF entity sends a session establishment acceptance message to the terminal device. The RAN network element sends the allocated resources to the terminal device through the core network element.

Enter the RAN network element; the RAN network element sends the RRC message to the terminal equipment. Alternatively, the UDM entity/PCF entity of the core network encapsulates the service information and the allocatable resource information information into a transparent container, and sends it to the terminal device through a NAS message or through an N2 and RRC message. Or, the core network element sends the service information and allocable resource information to the application-related server or NCIS function server (AF), and the application-related server or NCIS function server (AF) communicates with the terminal device through the interface message protocol Send to the terminal device.

When the resources are deactivated, the PC5 resource configuration information will be Is saved. However, RAN/CN does not allocate actual PC5 resources to terminal devices. When the terminal device has actual resource requirements, the required resources are activated through the service request process; at this time, the terminal device is allowed to request resource allocation according to actual needs while maintaining the session connection. In specific implementation, the third schematic diagram of the optional processing flow of the resource management method, as shown in Figure 5, includes the following steps:

Step S501: The terminal device establishes a session.

The session establishment process in the embodiment of the present invention is the same as the session establishment process in the related art, and will not be repeated here.

Step S502: The terminal device initiates a service establishment request.

Optionally, if the terminal device deactivates the session or deactivates the resources in the session, the terminal device also needs to initiate a service establishment request when it needs to establish a service, and the service establishment request is used to activate the session corresponding to the service and the corresponding resources . The service establishment request carries session information that needs to be activated; optionally, the service establishment request also carries QoS flow information or service flow information that needs to be activated.

Step S503: After receiving the service establishment request initiated by the terminal, the AMF entity sends the activated session or QoS flow information or service flow information to the SMF entity.

Step S504-Step S505, the SMF entity sends the session or QoS flow or service flow information that needs to be activated to the RAN network element.

In some embodiments, the terminal device requests resources from the network device during the session establishment process, and does not perform resource application and authorization during the group establishment process. During specific implementation, taking the control plane entity as an SMF entity as an example, the SMF entity receives a session establishment request message sent by the terminal device, and the session establishment request message carries resource request information. In the optional processing flow of the resource management method shown in FIG. 3, the SMF entity obtains the subscription information of the terminal device from the user plane entity (such as the UDM entity), and verifies the session establishment request of the terminal device according to the subscription information Whether the message passed. Alternatively, the SMF entity sends the received session establishment request message to a user plane entity (such as a UDM entity), and the UDM entity verifies whether the session establishment request message of the terminal device passes. Wherein, the subscription information includes: whether the terminal device is allowed to apply for the corresponding service on the PC5 interface, and/or the terminal device is allowed to apply for the resource attribute of the service on the PC5 interface.

Information and business-related information allocate resources; and once the resources are allocated, they are activated and effective. In the optional processing flow of the resource management method shown in FIG. 4, before the control plane entity receives the resource request message, the control plane entity sends the information of the allocatable resource sent by the user plane entity to the terminal device through the protocol message unit, The information of the allocatable resource is determined by the control plane entity after verifying the subscription information or authorization information of the terminal device. Alternatively, the control plane entity sends the information about the allocatable resources sent by the user plane entity to the terminal device through an RRC message, and the information about the allocatable resources is passed by the control plane entity in verifying the subscription information or authorization information of the terminal device. Determined afterwards. Alternatively, the control plane entity sends the allocatable resource information sent by the user plane entity to the terminal device via a NAS message; or the control plane entity sends the allocatable resource information sent by the user plane entity via N2 and RRC messages To the terminal device; the information of the allocatable resource is determined by the control plane entity after verifying the subscription information or authorization information of the terminal device.

When the resources are deactivated, the PC5 resource configuration information will be Is saved. However, RAN/CN does not allocate actual PC5 resources to terminal devices. When the terminal device has actual resource requirements, the required resources are activated through the service request process; at this time, the terminal device is allowed to request resource allocation according to actual needs while maintaining the session connection. In the optional processing flow of the resource management method shown in FIG. 5, after the terminal device deactivates the session or deactivates the resources in the session, the AMF entity receives the service establishment request message sent by the terminal device, and the service establishment The request message carries resource request information, and the AMF entity sends the service establishment request message to the SMF entity.
