Description
Technical Field
One or more embodiments of the present disclosure relate to the field of wireless communication and network virtualization technologies, and in particular, to a RAN-side network slice resource allocation method, apparatus, and electronic device.
Background
Network slicing is based on Network Function Virtualization (NFV) and Software Defined Networking (SDN) technologies, a single physical Network is divided into multiple independent end-to-end logical networks, which are isolated from each other and made programmable, and each Network can obtain Network functions and related resources required to meet specific service requirements. The network slice is a basic core technology for supporting wide vertical application services in a future network, and can meet differentiated service requirements brought by applications such as enhanced mobile broadband (eMBB), large-scale machine type communication (mMTC) and ultra-low delay high reliability communication (uRLLC).
In a 5G scene, slices share the same base station and server, and as the number of slices increases, emerging vertical application scenes put different demands on a wireless network. These requirements also face various challenges in a Radio Access Network (RAN), including large-scale Access of various terminals, which increases the computational complexity of a related algorithm in terms of the amount of resources required for computation, and increases the time delay of user service request response, affecting user experience; on the other hand, the allocation of radio network resources is in dynamic change due to the different number of users using the radio network at different times.
Due to the random mobility of users and the dynamic occupation and release of radio resources, the dynamic allocation strategy of resources becomes very complex. In addition, with the rapid development of the internet of things, the burst characteristic of the network service is stronger and stronger. Most of the current researches on RAN side network slice resource allocation methods are carried out under the condition that the environmental state is completely known, and the researches on the aspect of adapting to time-varying wireless network environments are incomplete, so that the whole wireless network has high throughput, low resource utilization rate and poor overall utility. In burst traffic, the static resource allocation method, although simple, will generate bandwidth waste, and the dynamic resource allocation method can adapt to the burst traffic demand.
Based on this, a method for realizing dynamic allocation of RAN-side network slice resources on the premise of guaranteeing the Quality of Service (QoS) requirements of users as much as possible is needed.

Detailed Description
For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
It is to be understood that unless otherwise defined, technical or scientific terms used in one or more embodiments of the present disclosure should have the ordinary meaning as understood by those of ordinary skill in the art to which this disclosure belongs. The use of the terms "comprising" or "including" and the like in one or more embodiments of the present specification is intended to mean that the element or item presented before the term "comprises" or "comprising" is included in the list of elements or items listed after the term and its equivalents, without excluding other elements or items.
As described in the background section, the existing network slice resource allocation method cannot adapt to the problem of dynamic change of RAN environment well, and does not consider a processing mode in case of emergency.
In view of this, one or more embodiments of the present specification provide a RAN-side network slice resource allocation method, which, with reference to fig. 1, includes the following steps:
step S101, in response to determining that an emergency situation about burst service occurs in a resource allocation period, a base station preferentially utilizes current idle resources to create an emergency slice with the highest priority for the burst service;
step S102, in response to determining that the emergency situation is released at the beginning of the next resource allocation period of the resource allocation period, the base station cancels the emergency slice, and restores the resource allocated to the emergency slice to idle resource.
It can be seen that, in the RAN-side network slice resource allocation method in one or more embodiments of the present specification, when RAN-side network slice resource allocation is performed, emergency situations related to emergency services in the RAN are considered, and a resource allocation method and a processing method after emergency situations are resolved are designed for the emergency situations, so that dynamic changes of a RAN environment can be adapted, and the utilization rate of resources is improved.
Hereinafter, the technical means of the present disclosure will be described in further detail with reference to specific examples.
Referring to fig. 2, a flowchart of a method for allocating RAN-side network slice resources in a normal situation in an embodiment of the present specification is shown, where a normal resource allocation mechanism is adopted in the normal situation, and the method includes the following steps:
step S201, the base station receives a radio resource request from a user at the current time.
In this step, assuming that the RAN-side network slice performs radio resource allocation with T as an allocation period, a network that changes slowly (for example, a cellular network in a rural area at night) may be simulated with a larger value of T, and a network that changes rapidly (for example, a cellular network in a urban area during the day) may be simulated with a smaller value of T. At the beginning of each allocation period T, the base station receives a radio resource request from the user equipment at the current time.
Step S202, the base station calculates the amount of radio resources required by the corresponding RAN side network slice according to the radio resource request of the user, and sets the priority of each RAN side network slice.
In this step, the base station determines, according to the radio Resource request of the user equipment, the number of radio resources, that is, the number of Physical Resource Blocks (PRBs), required by the RAN-side network slice to satisfy the terminal service request.
In addition, it is also necessary to set priorities for each RAN-side network slice according to the characteristics of the service provided by each RAN-side network slice. The division of the RAN-side network slice priorities requires evaluation of the service requested by each user according to the current network scenario and signal environment. For example: generally, the low-latency service priority of the urrllc is higher than that of the other urrllc slices, and the higher priority needs to be allocated to the urrllc slices sensitive to the delay. For example, some conversational services, voice and video telephony, are the most typical conversational services, and are characterized by a small end-to-end delay. Some streaming media services are real-time, but because the streaming media services are unidirectional transmission and do not need interaction, the real-time requirements are less strict than those of session services, and certain packet loss rate and packet error rate are allowed. There are also some background class, background class business, including some automatic background e-mail reception, multimedia message or receiving some files and database downloads, the characteristic of this kind of business is that users have no special requirement for transmission time, but the requirement for packet loss rate is very high. Then in terms of latency, the priority order from high to low is: network slices of session class, network slices of streaming media class, and network slices of background and background classes.
Step S203 determines whether the total number of radio resources required for each RAN-side network slice is greater than the total number of radio resources owned by the base station.
Step S204, if the total number of radio resources required by each RAN-side network slice is greater than the total number of radio resources owned by the base station, the base station allocates radio resources to each RAN-side network slice (that is, the base station allocates resources to the RAN-side network slice with a high priority in priority) in the order from high to low of the priority of each RAN-side network slice, and after all the total number of radio resources owned by the base station is allocated, the remaining network slices refuse to access.
Step S205, if the total number of radio resources required by each RAN-side network slice is less than or equal to the total number of radio resources owned by the base station, the base station allocates radio resources to each RAN-side network slice according to the number of radio resources required by each RAN-side network slice.
In this step, referring to fig. 3a, a radio resource allocation method when the total number of radio resources required for each RAN-side network slice is smaller than the total number of radio resources owned by the base station is shown. In the figure, S1 to S6 are 6 RAN-side network slices corresponding to different user radio resource requests, and during the initial radio resource allocation process, the allocation principle of concentrating the idle radio resources as much as possible should be followed for the subsequent radio resource reuse.
Step S206, determining whether the number of radio resources required by each RAN-side network slice at the current time is less than the number of radio resources allocated to the RAN-side network slice in the previous resource allocation period.
In this step, in order to consider the dynamically changing network requirements, the radio resources allocated to each RAN-side resource slice are dynamically adjusted according to the real-time requirements of the user, and it needs to be determined whether the number of radio resources required by each RAN-side resource slice at the current time is less than the number of radio resources allocated to the RAN-side resource slice in the previous resource allocation period. Referring to fig. 3b, a schematic diagram of a resource change required by a RAN-side network slice at a current time compared to a previous resource allocation period in an embodiment of the present disclosure is shown. Comparing fig. 3a and fig. 3b, it can be seen that the number of radio resources required by the RAN-side network slices S2, S5, and S6 at the current time is less than the number of radio resources allocated in the previous resource allocation period, and the number of radio resources required by the RAN-side network slices S1, S3, and S4 at the current time is greater than the number of radio resources allocated in the previous resource allocation period.
Step S207, for the RAN-side network slice whose number of radio resources required at the current time is smaller than the number of radio resources allocated in the previous resource allocation period, reserves the number of radio resources required at the current time at the original radio resource position, and restores the redundant radio resources to the idle radio resources.
In this step, referring to fig. 3c, a schematic diagram of resource allocation of the RAN-side network slice at the current time in an embodiment of this specification is shown, and comparing with fig. 3a and fig. 3b, it can be seen that the RAN-side network slices S2, S5, and S6 reserve the amount of radio resources required at the current time in their original radio resource positions, and restore redundant radio resources to idle radio resources.
Step S208, for the RAN-side network slice whose number of radio resources required at the current time is greater than the number of radio resources allocated in the previous resource allocation period, the number of radio resources required at the current time is reserved at the original radio resource position, and the remaining radio resources that are still required are obtained at the idle radio resources.
In this step, comparing fig. 3c with fig. 3a and fig. 3b, it can be seen that the RAN-side network slices S1, S3, and S4 reserve the amount of radio resources required at the current time in their original radio resource positions, and obtain the remaining radio resources required at the idle radio resources.
Further, in consideration of the fact that a large number of short and urgent emergency traffic demands (i.e., sudden data streams requiring spectrum resources, such as emergency medical care, emergency traffic accidents, emergency information, etc.) easily occur in the RAN, a resource allocation method and a post-emergency relief process are designed for emergency situations. Referring to fig. 4, a flowchart of a method for allocating RAN-side network slice resources in an emergency in one embodiment of the present specification, where an emergency resource allocation mechanism is adopted in the emergency, includes the following steps:
step S401, the base station receives the emergency wireless resource request of the burst service from the user equipment at the current time.
Step S402, the base station calculates the amount of radio resources needed by the corresponding RAN side emergency network slice according to the emergency radio resource request of the user equipment, and preferentially utilizes the current idle resources to create the RAN side emergency network slice with the highest priority for the burst service.
Step S403, determining whether the current idle radio resource of the base station can meet the total radio resource requirement of the RAN-side emergency network slice.
Step S404, if the current idle wireless resource of the base station can not meet the total wireless resource requirement of the RAN side emergency network slice, the current idle resource is utilized, and after the idle resource is utilized, the resource of the RAN side network slice with low priority is preempted according to the sequence from low to high of priority, so that the RAN side emergency network slice is created.
Step S405, if the current idle radio resource of the base station can meet the total radio resource requirement of the RAN-side emergency network slice, creating the RAN-side emergency network slice at the current idle radio resource.
In this step, referring to fig. 3d, a schematic diagram of resource allocation of a RAN-side emergency network slice in an embodiment of this specification is shown, and as can be seen from the diagram, if the total amount of radio resources required by the RAN-side emergency network slice S7 is less than the amount of idle radio resources at the current time, a RAN-side emergency network slice S7 is created at the idle radio resources.
Step S406, at the beginning of the next resource allocation period, determining whether the emergency of the emergency service corresponding to the RAN-side emergency network slice is released.
In this step, since the burst service in the RAN is generally short and urgent, it is necessary to determine whether the emergency of the burst service is released at the start time of the next allocation cycle, so as to provide a method for processing release and unreleased emergency, thereby improving the utilization rate of radio resources.
Step S407, if the emergency is resolved, the base station cancels the RAN-side emergency network slice, and restores the radio resource allocated to the RAN-side emergency network slice to an idle radio resource.
Step S408, if the emergency is not resolved, the base station dynamically adjusts the RAN-side emergency network slice together with the rest RAN-side network slices in the normal situation according to the normal situation.
In this step, if the emergency is not resolved, the base station allocates resources to the RAN-side emergency slice and the rest of RAN-side network slices according to a normal resource allocation mechanism, so as to dynamically adjust the radio resources of each RAN-side network slice.
It can be seen that, in the RAN-side network slice resource allocation method provided in the embodiments of the present specification, allocation of RAN-side network slice resources is divided into normal situations and emergency situations, a large number of short and emergency burst services in the RAN are considered, and a resource allocation method and a processing method after emergency situation is resolved are designed for the emergency situations, so that the method can adapt to dynamic changes of RAN environments; meanwhile, on the premise of ensuring the Quality of Service (QoS) requirement of a user as much as possible, considering the condition that the wireless resources cannot meet the requirements of all RAN side network slices, distributing the priority to the RAN side network slices and distributing the resources according to the priority; in addition, the resource requirement of the dynamic change of the user is considered, a dynamic adjustment allocation strategy is introduced, the resources allocated to each RAN side network slice are adjusted according to the real-time requirement, and the utilization rate of the resources is improved.
It is to be appreciated that the method can be performed by any apparatus, device, platform, cluster of devices having computing and processing capabilities.

for each slice in the emergency slice and the rest slices, determining the resource amount required by the slice according to a resource request from user equipment, and setting a priority for the slice according to the characteristics of the service provided by the slice, wherein the priority is ranked from high to low into a session-class network slice, a streaming media-class network slice and a background-class network slice;
responding to the fact that the sum of the resource amount needed by each slice is larger than the total resource amount owned by the base station, distributing resources to each slice according to the sequence from high to low in priority, and refusing access of the rest slices until the total resource amount is completely distributed;
the base station further allocates resources to the emergency slice and the remaining slices according to a normal resource allocation mechanism, including: for each of the emergency slice and the remaining slices,
in response to the fact that the resource quantity needed by the slice is smaller than the resource quantity allocated in the last resource allocation period, reserving the resource quantity needed by the current resource allocation period at the original resource position of the slice, and recovering redundant resources into idle resources; and
in response to the fact that the resource quantity needed by the slice is larger than the resource quantity allocated in the last resource allocation period, reserving the resource quantity needed by the current resource allocation period at the original resource position of the slice, and obtaining the remaining needed resources from the idle resources;
the base station preferentially utilizes the current idle resources to create the emergency slice with the highest priority for the burst service, and the method comprises the following steps:
in response to determining that the current idle resources cannot meet the resource requirements of the emergency slice, first utilizing the current idle resources and then preempting resources of a low-priority slice to create the emergency slice;
the resource allocation periods with larger values are used to simulate slower changing networks, while the resource allocation periods with smaller values are used to simulate faster changing networks.
5. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable by the processor, characterized in that the processor implements the method according to any of claims 1 to 3 when executing the computer program.
