[0050] To make the technical problems, technical solutions, and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0051] To solve the problem that the existing resource reservation method has application limitations and cannot achieve all-round service guarantee, an embodiment of the present invention provides a resource reservation method. A network management function entity can send resource reservation information for a target slice service to a network node. The resource reservation information includes time-domain resource reservation information. By using time-domain resource reservation, it is possible to achieve the guarantee of high-reliability and periodic transmission services that are delay-sensitive and interference-sensitive, so as to solve the problem that the existing resource reservation method has application limitations and cannot achieve all-round service guarantee.

[0052] Optionally, the resource reservation method according to an embodiment of the present invention is applied to a network management function entity. As Figure 1 shown, the method includes:

[0053] S110, sending resource reservation information for a target slice service to a network node; wherein, the resource reservation information includes time-domain resource reservation information.

[0054] It should be noted that in the embodiment of the present invention, optionally, the network management function entity may be a Network Slice Subnet Management Function (NSSMF) entity, which can implement the reservation configuration of slice services; the network node may be a base station, which can implement the scheduling of slice services.

[0055] Optionally, in the resource reservation method according to an embodiment of the present invention, the resource reservation information further includes frequency-domain resource reservation information.

[0056] When adopting the resource reservation method according to the embodiment of the present invention, for services that require deterministic rate guarantee, the resource reservation information sent to the network node may include frequency-domain resource reservation information; for interference-sensitive high-reliability services, or delay-sensitive services, or services that need to be periodically transmitted, which may configure different frame structures and cause cross-slot interference between public and private networks, the resource reservation information sent to the network node may include time-domain resource reservation information.

[0057] By adopting this method, for target slice services with different service requirements, corresponding specific resources can be reserved respectively to meet the service guarantee of different service requirements, improve the service experience of services with special requirements for delay, reliability, and periodic transmission, and solve the problem that the existing resource reservation method has application limitations and cannot achieve all-round service guarantee.

[0058] Optionally, in the resource reservation method according to an embodiment of the present invention, the time-domain resource reservation information includes the slice identifier of the target slice service and the resource information of the reserved time-domain resources.

[0059] Optionally, the resource information includes one of continuous reserved time slots, time slot reservation pattern, and time slot reservation period.

[0060] In an embodiment of the present invention, optionally, the slice identifier of the target slice service can be used to indicate the target slice service for which resources need to be reserved. The slice identifier can be in the form of a slice identifier list, that is, the slice list indicating the slices for which resources need to be reserved is formed through the slice identifier list, and the slice services recorded in the slice list are target slice services.

[0061] Optionally, the slice identifier is identified by a Public Land Mobile Network (PLMN) identifier and / or a Network Slice Selection Assistance Information (NSSAI) identifier.

[0062] Optionally, the resource information may include continuous reserved time slots, which are used to indicate that for the target slice service, priority scheduling is performed within several consecutive uplink or downlink time slots when the service arrives, and a quick response is required.

[0063] Optionally, the resource information may include a time slot reservation pattern, which is used to indicate for the target slice service in which time slots to reserve, that is, to indicate the distribution pattern of the reserved time slots for the target slice service, so as to preferentially schedule the target slice service within the indicated time slots.

[0064] For example, in the 4.9G networking mode, the reserved time slots indicated by the time slot reservation pattern are {4, 8, 9}+10n, where n = 0, 1, 2….

[0065] Optionally, the resource information may include a time slot reservation period, which is used to indicate that for the target slice service, time slot resources are reserved every corresponding indicated time slot reservation period, so as to ensure that the target slice service can be preferentially scheduled on the reserved time slot resources.

[0066] Optionally, when the resource reservation information includes frequency domain resource reservation information, the frequency domain resource reservation information may include the slice identifier of the target slice service and the resource information of the reserved frequency domain resources.

[0067] In the resource reservation method according to the embodiment of the present invention, optionally, the method further includes:

[0068] Determine the resource reservation information according to the slice attributes of the target slice service and the Service Level Agreement (SLA) requirements.

[0069] Optionally, the slice attributes of the target slice service can be used to indicate whether time-frequency domain resource reservation is required for the target slice service.

[0070] Among them, the slice attributes can be sent from a Communication Service Management Function (CSMF) entity to a network management function entity.

[0071] Specifically, when a user subscribes to the CSMF, the subscription information needs to include whether time-frequency domain resource reservation is performed for the slice service. For example, if a tenant has strong demands for deterministic guarantees of slice service rate and latency, the resource reservation service can be subscribed. Through time-frequency domain resource reservation, deterministic rate, latency, and reliability guarantees can be provided for the service in case of network congestion. The CSMF sends the field indicating whether resource reservation is required to a Network Slice Management Function (NSMF) entity and the NSSMF.

[0072] Among them, when the NSSMF receives that the slice attribute of the target slice service indicates that time-frequency domain resource reservation is required, the resource reservation information is determined according to the requirements of the Service-Level Agreement (SLA).

[0073] Specifically, the resource reservation information is determined according to the slice attributes of the target slice service and the requirements of the Service-Level Agreement (SLA), including at least one of the following:

[0074] When the slice attribute indicates that resource reservation is required and the SLA requirement is rate guarantee, the determined resource reservation information includes frequency domain resource reservation information;

[0075] When the slice attribute indicates that resource reservation is required and the SLA requirement is at least one of latency guarantee, reliability guarantee, and periodic transmission, the determined resource reservation information includes time domain resource reservation information.

[0076] That is, if the slice SLA requirement is mainly for rate guarantee, frequency domain resource reservation is adopted. If the slice SLA requirement is mainly for latency, reliability guarantee, or periodic transmission, time domain resource reservation is adopted, and continuous reserved time slots, time slot reservation patterns, or time slot reservation periods are configured according to the slice SLA requirements to indicate the time domain resources that need to be reserved.

[0077] For example, if the target slice service is a small packet service sensitive to latency (such as a factory control service), the resource reservation information configured by the NSSMF includes a continuous reservation time slot field, indicating that the base station performs priority resource reservation and scheduling for several consecutive time slots when the slice service arrives, that is, ensuring that the slice service has the highest scheduling priority within the earliest several consecutive time slots after the service arrives, so as to ensure that the slice service receives a scheduling response first.

[0078] Among them, the number of consecutive time slot reservations is planned and configured by the NSSMF. If there are remaining resources after scheduling, other services can be scheduled. It should be noted that this priority scheduling strategy can be applied to each traffic flow belonging to the reserved slice list of the target slice service. Since the arrival times of each traffic flow within the slice may be different, the time slots with priority guarantee may also be different.

[0079] In another implementation, if the target slice service is a service sensitive to interference (such as a smart grid service), that is, stable reliability guarantee is required and large fluctuations in service performance due to co-channel / co-frequency interference cannot be tolerated, the resource reservation information configured by the NSSMF according to the time slot structure includes a time slot reservation pattern to ensure that the transmitted time slots avoid cross-time slot interference as much as possible.

[0080] For example, the time slot reservation pattern is related to the frame structure. Taking the private network 4.9G 2.5ms single-cycle frame structure as an example, the time slot ratio is DSUUU, and the public network 2.5ms double-cycle frame structure is DDDSU DDSUU. As Figure 2 shown, the uplink data of the private network in uplink time slots 2, 3, and 7 may be interfered by the public network, while the interference can be avoided in uplink time slots 4, 8, and 9. Based on the above analysis, the time slot reservation pattern can be designed as {4, 8, 9}+10n (n = 0, 1, 2...). Through the configured time slot reservation pattern, within the reserved time slots, the target slice service can achieve absolute priority scheduling and avoid interference.

[0081] In yet another implementation, if the target slice service is a periodic small packet service, resources can be reserved for the service periodically to ensure priority scheduling of the periodic service and improve the service experience. The specific method is as follows:

[0082] For example, in scenarios such as industrial parks and factories, usually a type of service has the same service model, including packet size, packet sending interval, etc. This type of service can be configured as a slice, and the time slot reservation period field can be configured according to the packet sending interval in the slice SLA metrics. For example, if the slice service period is 20 ms (the slice service period can be obtained through manual input of service requirements, AI service model learning, etc.), when the base station identifies that a QoS flow belongs to the slice that needs to be reserved (wherein, in the PDUSession Resource Setup signaling, the core network notifies the base station which slice the QoS flow belongs to), and there is traffic arriving in a certain time slot, it instructs the base station to reserve time slot resources for this QoS flow every 20 ms to ensure priority scheduling.

[0083] It should be noted that the periodic reservation resources corresponding to the configured time slot reservation period are for each traffic flow in the traffic list corresponding to the target slice service. Since the arrival times of each traffic flow within the slice may be different, the reserved time slots may also be different.

[0084] Based on the resource reservation information of the target slice service determined in the above manner, the NSSMF distributes one of the slice identifier list of the target slice service that needs to be reserved, the configured continuous reserved time slots, the reserved time slot pattern, and the time slot reservation period to the base station.

[0085] The base station performs resource reservation and scheduling according to the resource reservation information distributed by the NSSMF. Specifically, within the reserved time slots, the services in the reserved slice list belonging to the target slice service are preferentially scheduled. Only when it is ensured that the slice service scheduling is completed and there are remaining resources, can other services be scheduled. Simply put, it ensures that the target slice service has absolute scheduling priority within the reserved time slots.

[0086] Another aspect of the embodiments of the present invention also provides a resource reservation method, which is applied to a network node, such as Figure 3 shown, the method includes:

[0087] S310, obtaining the resource reservation information of the target slice service sent by the network management function entity; wherein, the resource reservation information includes time domain resource reservation information;

[0088] S320, according to the resource reservation information, preferentially scheduling the target slice service on the reserved resources indicated by the resource reservation information.

[0089] By adopting the resource reservation method described in the embodiments of the present invention, the network management function entity can send time-domain resource reservation information to network nodes. For target slice services with different service requirements, specific time-domain resources can be reserved respectively to meet the service guarantee for different service requirements. In addition, through the resource scheduling of the base station, the service guarantee effect can be improved.

[0090] For the resource reservation method described in the embodiments of the present invention, optionally, the resource reservation information further includes frequency-domain resource reservation information.

[0091] By adopting the resource reservation method described in the embodiments of the present invention, for services that require deterministic rate guarantee, the resource reservation information sent to network nodes may include frequency-domain resource reservation information; for interference-sensitive high-reliability services, or delay-sensitive services, or services that need to be sent periodically, which may be configured with different frame structures resulting in cross-slot interference between public and private networks, the resource reservation information sent to network nodes may include time-domain resource reservation information.

[0095] Optionally, for the resource reservation method, wherein the method further includes:

[0096] After scheduling the target slice service, if there are remaining resources in the reserved resources indicated by the resource reservation information, other slice services are scheduled on the remaining resources.

[0097] For the resource reservation method described in the embodiments of the present invention, the network management function entity can configure resource reservation information according to the slice SLA requirements. This resource reservation information can include not only frequency-domain resource reservation information but also time-domain resource reservation information. According to the frequency-domain resource reservation information and / or time-domain resource reservation information, the base station performs absolute priority scheduling to better meet the service SLA requirements.

[0098] Optionally, in the method described in the embodiments of the present invention, the resource reservation information includes time-domain resource reservation information. This time slot reservation guarantee mechanism can be used for slice services with special requirements for delay, reliability, and periodic packet transmission, and guarantees the slice service experience through time slot reservation and priority scheduling.
