Description
Technical Field
The disclosure relates to the technical field of computers, in particular to a system and a method for allocating slice resources of the internet of things, electronic equipment and a storage medium.
Background
In recent years, with the high-speed development and construction of a power grid, diversified service demands, increased data flow and massive terminal devices pose new challenges to the programmability, isolation, customization and other capabilities of the current power communication Network architecture, many defects of the traditional Network cause service and resource providers to find a more dynamic and more predictive resource management system architecture, and a 5G Network slice architecture based on Network Function Virtualization (NFV) technology and Software Defined Networking (SDN) technology is generated due to operation, so that the flexibility of the Network is enhanced, the differentiated service demands are met, and meanwhile, the Network construction cost is saved.
Network slicing is based on virtualization technology, which cuts physical infrastructure resources (e.g., access networks, transport networks, core networks) into multiple logically independent virtual end-to-end logical networks, each of which can obtain the network functions and related resources (e.g., computing, network, memory, and storage resources) needed to meet specific service requirements. The network slice supports high dynamic expansion of a network structure, and can meet the requirements of most of power grid services on high bandwidth, low time delay and large-scale connection in the future. The network slice is introduced to realize the flexible, differentiated and large-scale connection communication capability of the power grid, so that the system cost can be greatly reduced, the communication time delay is reduced and the network service efficiency is improved while the user service quality is ensured. Meanwhile, the use of the network slice can create customized service for users in the power industry, so that the requirements of future power grid service scenes are better met, and the application innovation of energy Internet services is promoted. However, the existing network slicing solution brings higher complexity in calculating the required resource amount, increases the time delay of the user service request response and the calculation amount of resource allocation, and affects the user service quality and the network efficiency. On the other hand, the current situation of lack of radio resources provides a new challenge for resource allocation of current slices, the use scenes of each frequency band are basically specified, the fixed allocation mode of spectrum resources causes that the bandwidth required by emerging services is increased and limited, and the radio bandwidth is difficult to meet the requirement of rapidly increasing mobile data traffic. Most of the existing network slice solutions have defects in the aspects of efficiently utilizing limited spectrum resources, ensuring resource isolation among different slices and among different users, and cannot efficiently utilize resources under the condition of network resource shortage, thereby causing low network benefits.

The details of the embodiments of the present disclosure are described in detail below with reference to specific embodiments.
Fig. 1 shows a block diagram of an internet of things slice resource allocation system according to an embodiment of the present disclosure. As shown in fig. 1, the system for allocating slice resources of the internet of things comprises an inter-slice controller and an intra-slice controller; wherein the content of the first and second substances,
the inter-chip controller is suitable for receiving a resource service request of a terminal, calculating wireless network resource information required by the resource service request, determining a target slice allocated for the resource service request according to the wireless network resource information, and sending the wireless network resource information to an on-chip controller corresponding to the target slice;
and the on-chip controller corresponding to the target slice receives the resource service request and the wireless network resource information sent by the inter-chip controller, and allocates wireless network resources in the current slice for the resource service request of the terminal according to the wireless network resource information.
In this embodiment, the internet of things may be, for example, an electric power internet of things, but it is understood that other internet of things are also applicable to the embodiment of the present disclosure.
Taking an electric power internet of things as an example, the physical grid slice resource allocation system in the embodiment of the disclosure may receive resource service requests of a power grid terminal, such as a substation terminal monitoring request, an electric meter data acquisition request, and the like, at a slice example layer by dividing physical resources into a plurality of network slices, define the resource service requests and calculate physical resource requirements according to communication demand characteristics of different power grid services, and construct different service slices to better meet the resource service requirements of different power grid terminals.
The slice instance layer of the slice resource allocation system in the embodiment of the present disclosure at least includes an inter-slice controller and an intra-slice controller; the inter-chip controller is responsible for responding to a resource service request of the terminal to the network slice, processing wireless network resource information, managing the life cycle of the network slice and the like, is used for ensuring the isolation of wireless network resources among the slices, and interacts with other layers in a system architecture; and the on-chip controller is responsible for the distribution of wireless network resources in the slice, ensures the wireless network resource isolation of each terminal in the slice, and distributes the wireless network resources according to the priority of the service when the resource service request exceeds the load bearing of the slice too much.
In some embodiments, after receiving a resource service request of a terminal, an inter-chip controller calculates wireless network resource information required by the resource service request, where the wireless network resource information may include, but is not limited to, the number of physical resource blocks and the type of wireless network resource. The pre-divided network slices can be preset to different resource types according to different physical resources allocated to the network slices, such as dedicated resources, continuous resources, discontinuous resources, and the like. The inter-chip controller may allocate a suitable target slice to the resource service request according to the wireless network resource information, and send the wireless network resource information to the on-chip controller corresponding to the target slice.
In some embodiments, the internet of things slice resource allocation system may create a logical platform on top of physical resources in advance and divide the logical platform into different logical instances, where each logical instance represents a network slice. The wireless network physical resources within the system may be pre-partitioned to different network slices. Different network slices may be managed by different on-chip controllers. For example, n network slices are divided in the system, and m < ═ n on-chip controllers can be set, and in a preferred embodiment, m can be equal to n, that is, the network slices and the on-chip controllers have a one-to-one correspondence relationship. And after the on-chip controller corresponding to the target slice receives the resource service request and the wireless network resource information sent by the inter-chip controller, allocating the wireless network resource in the target slice for the current resource service request of the terminal according to the wireless network resource information so as to be used by the terminal.
In some embodiments, the on-chip controller and the inter-chip controller may be implemented in hardware, for example, the on-chip controller and the inter-chip controller may be implemented in a processor. It is of course understood that in other embodiments, the on-chip controller and the inter-chip controller may be implemented using software.
In an optional implementation manner of this embodiment, the on-chip controller is further adapted to obtain a radio network resource requirement of a terminal allocated in a slice, and predict a radio network resource required by the slice in a next resource allocation period.
In this optional implementation manner, a resource estimation module may be disposed on the on-chip controller, and configured to estimate, according to a wireless network resource requirement of a terminal in a current slice, a resource that may be needed by the slice in a next resource allocation period, so as to provide a reference for the on-chip controller to adjust a resource allocation policy.
In an optional implementation manner of this embodiment, the on-chip controller is further adapted to evaluate a priority of a resource service request of the terminal, and allocate a wireless network resource to the resource service request according to the priority.
In this optional implementation manner, a service evaluation module may be further disposed on the on-chip controller, and configured to evaluate a priority of a resource service request of the terminal, and enable the on-chip controller to allocate available wireless network resources to the terminal according to the priority.
In an optional implementation manner of this embodiment, the system for allocating slice resources of the internet of things further includes: the virtual resource management and orchestrator is suitable for dividing physical resource blocks in a system into different physical resource block groups, setting different resource types for each physical resource block group, dividing the physical resource block groups into different slices in advance according to the resource types required by each slice, forming virtual network resource information according to the division results, and feeding the virtual network resource information back to the inter-slice controller.
In the optional implementation manner, the virtual Resource management and orchestrator optionally combines disjoint Physical Resource blocks PRB into a Physical Resource Block Group (PRBG) according to service requirements; and defining the resource block group PRBG as different resource types (dedicated resources, continuous resources and discontinuous resources) according to a physical resource mapping mode; according to the type of the resource needed by the slices, the PRBG is divided into each slice in advance, and the pre-allocation result is fed back to the inter-slice controller; and virtualizing the wireless resources according to different resource types to form a wireless resource virtual view, wherein the on-chip controller can form the slice resource pool according to the virtual view. Each slice can only see the virtual view of the virtualized resources but cannot see the exact physical frequency position of the virtualized resources, so that other slices are prevented from accessing and even deducing the actual physical resources allocated to the current slice, and the isolation of wireless network resources is effectively guaranteed. The on-chip controller may adapt the radio network resources within a chip to the physical resources when allocating them to the terminal. But such adaptation may not follow the physical resources pre-allocated to the network slice by the virtual resource management and orchestrator, but may be adjusted according to the actual situation. For example, the virtual resource management and orchestrator allocates x physical resource blocks to the current slice, and the on-chip controller may allocate y (y < ═ x) physical resource blocks to the current slice for the terminal to use.
In an optional implementation manner of this embodiment, the intra-chip controller feeds back the radio network resource information allocated to the terminal to the inter-chip controller; the inter-chip controller feeds the wireless network resource information back to the virtual resource management and orchestrator; and the virtual resource management and orchestrator counts the unallocated wireless network resources and types according to the wireless network resource information.
In this optional implementation manner, after the on-chip controller completes the allocation of the on-chip resources, the on-chip controller may feed back a resource allocation result to the inter-chip controller, and the inter-chip controller feeds back the resource allocation result to the virtualized resource layer, and the virtualized resource layer may count the number and type of the unallocated resources, and then adjust the physical resource block groups allocated to the slices.
In an optional implementation manner of this embodiment, the on-chip controller is further adapted to periodically check the state of the terminal, and after the state of the terminal is switched from the active mode to the idle mode, reallocate the radio network resources released by the terminal to other terminals in the active mode in the slice.
In this alternative implementation, a terminal state controller may be further configured to periodically check the state (active or idle) of the terminal, and when the terminal to which the wireless network resource is allocated transitions from the active mode to the idle mode, it will release the allocated resource. Then, the chip controller redistributes the released resources to other terminals in the active mode in the chip, and the resource utilization rate is improved.
The embodiment of the disclosure adopts a two-stage management idea between chips and inside a chip, and improves the utilization rate of wireless resources by combining the active state of a monitoring terminal of an on-chip controller with the reuse of idle resources between chips; while inter-slice and intra-slice resource isolation is achieved by a combination of intra-slice presentation of a virtual view of the wireless resources separate from the physical resource locations and inter-slice allocation of disjoint physical resource blocks. Meanwhile, by predicting the resources possibly required in the next stage, reference is provided for the inter-chip controller to adjust the resource allocation strategy, the complexity in the aspect of calculating the required resource amount is reduced, the service request response time delay is reduced, and the overall system benefit is improved.
