Detailed Description
The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable those skilled in the art to better understand and practice the invention and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The technical scheme of the invention is further elaborated below with reference to the drawings and specific embodiments.
Fig. 1 shows an application scenario of a radio resource scheduling method according to an embodiment of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a three-layer pyramid scheduling architecture is adopted, where a first layer scheduling architecture is a scheduling manager and a resource manager, where the scheduling manager and the CU have interfaces and are responsible for creating a scheduling pool according to scheduling requirements, the resource manager obtains resource requirements of a corresponding scheduling pool from the scheduling manager, and creates a resource pool for the corresponding scheduling pool.
The second layer is a scheduling pool and a resource pool, wherein each scheduling pool may correspond to a PLMN (Public Land Mobile Network ) level resource scheduling requirement, for example: the resource pools correspond to the exclusive resources and the shared resources of an operator according to the scheduling requirements of an operator, and each scheduling pool and each resource pool are mapped in a one-to-many relationship, namely, each scheduling pool can correspond to the resource scheduling of one or more resource pools.
The third layer is a scheduler and a resource block, which are the smallest entities for scheduling and distributing the resources, and are respectively created by a scheduling pool and a resource pool, and each scheduler corresponds to the scheduling requirement and the resource requirement of one slice, for example: high speed channel network slices. Similar to the second layer, here the schedulers and resource blocks are also mapped in a one-to-many relationship, i.e. each scheduler may correspond to a resource schedule of a plurality of resource blocks. Meanwhile, a communication interface is configured between the scheduler and the multiplexing entity or the demultiplexing entity, and PHY (Physical Layer) resources are scheduled through the multiplexing entity or the demultiplexing entity.
In an actual resource scheduling process, the scheduling manager may obtain resource requirement information from a direct CU (Centralized Unit), for example: PLMN information and network slice information, a scheduling pool is established or managed according to the acquired resource demand information, communication is carried out between a scheduling manager and the resource manager, the resource manager acquires the resource demand information from the scheduling manager, and the resource pool is established and managed according to the resource demand information. Further, the scheduling pool establishes and manages a scheduler according to the resource demand information, the resource pool obtains the resource demand information from the scheduling pool, and establishes and manages resource blocks according to the resource demand information.
For example, operators a, B and C share the radio network resources of the happy cell, with 30% of the resources of the happy cell being exclusively occupied by operator a, 40% of the resources being exclusively occupied by operator B, 10% of the resources being exclusively occupied by operator C, and the remaining 20% of the shared resources belonging to the three operators.
At this time, when the resource request of the operator a is received and 40% of the radio resource demand is needed, the scheduling manager establishes a scheduling pool responsible for the resource scheduling management of the operator a, and the resource manager establishes two resource pools according to the resource demand, wherein one is a resource pool including 30% of exclusive resources of the operator a, and the other is a shared resource pool established by taking 10% of resources from 20% of shared resource pools.
For network slicing requirements, for example: the operator B sends a resource requirement for the high speed channel resource schedule to the CU. After receiving the resource demand information from the CU, the scheduling manager firstly determines a scheduling pool of the operator B, then the scheduling pool determines whether a scheduler corresponding to the scheduling pool comprises a scheduler responsible for high-channel resource scheduling, if yes, determines whether scheduling parameters of the scheduler meet requirements, and if no, establishes a corresponding scheduler. Meanwhile, the resource pool is responsible for establishing and managing resource blocks corresponding to the scheduler.
RLC (Radio Link Control, radio link layer control protocol) is responsible for specific resource scheduling parameter management, such as: the scheduling parameters are sent to the scheduler. Scheduling parameters may include Qos requirements, queue buffering, throughput, PDB, MCS, HARQ status, etc. These scheduling parameters may be fed back to the RLC by the resource collector according to the parameter status of the resource blocks.
OAM (Operation Administration and Maintenance, operation and maintenance management) generally classifies management work of networks into 3 major classes according to actual needs of operator network operations: operation (Operation), administration (Maintenance), maintenance (Maintenance). The operation mainly completes analysis, prediction, planning and configuration work of daily network and business; maintenance is mainly a daily operation activity performed on testing and fault management of a network and services thereof. OAM is directly responsible for operation, administration and maintenance of the scheduler.
Fig. 2 is a schematic diagram of an implementation flow of a radio resource scheduling method according to an embodiment of the present invention.
Referring to fig. 2, the radio resource scheduling method according to the embodiment of the present invention at least includes the following operation flows: operation 201, obtaining public land mobile network information and slice information of a radio resource requested to be scheduled in a scheduling request; an operation 202 of determining a scheduler for scheduling radio resources and a resource block corresponding to the scheduler according to public land mobile network information and slice information; operation 203, the scheduler obtains wireless resources from the resource blocks according to the scheduling request, and performs wireless resource scheduling; the scheduler is used for scheduling the wireless resources corresponding to the specified slice information.
In operation 201, public land mobile network information and slice information of a radio resource requested to be scheduled in a scheduling request are acquired.
In this embodiment of the present invention, the scheduler is mainly used for scheduling resources, and here, first, the functional division of the lower scheduler is explained, and main functional modules of the scheduler include:
a scheduling feedback module, configured to collect scheduling information in a scheduling process, feedback the collected scheduling information to a scheduling pool for the scheduling pool to make a decision on scheduling resources, and feedback the scheduling information to a BWP (Bandwidth Part) management module for the BWP management module to dynamically adjust the BWP of the UE; the BWP management inputs information to the resource mapping module for use in resource application after adjusting a part of BWP of the UE.
And the strategy management module is used for acquiring the scheduling strategy from the scheduling pool and maintaining the scheduling factors. And inputting the scheduling strategy into a scheduling main process, obtaining scheduling priority according to the scheduling factors and the input scheduling parameters, and inputting the scheduling priority into a packet flow manager.
And the resource mapping management module is responsible for maintaining mapping between the scheduler and the resource blocks and scheduling characteristics of each resource block, and acquiring proper resources from the resource blocks.
The packet stream management module is responsible for managing a packet stream chain table of the current scheduler and providing scheduling reference to a scheduling main process;
the scheduling main process module is responsible for scheduling process of each scheduling TTI (Transmission Time Interval ), and notifies multiplexing entity of scheduled MAC (Multiple Access Channel ) and SDU (Service Data Unit, service data unit) information.
Wherein, BWP management is responsible for maintaining BWP information of UE (User Equipment, user terminal) and controlling BWP activation and handover. The scheduling feedback information provides a reference for BWP handover for BWP management, which inputs the BWP information of the UE into a resource mapping unit of the scheduler for use in resource allocation. The BWP management acquires BWP reception capability of the UE from the CU and acquires configuration information of the BWP, facilitating BWP selection management of the UE.
In this way, the scheduler may collect scheduling information, including resource demand information, using the scheduling feedback module.
Determining a scheduler for scheduling the radio resource and a resource block corresponding to the scheduler according to the public land mobile network information and the slice information in operations 202 to 203; acquiring wireless resources from the resource blocks according to the scheduling request at the scheduler, and performing wireless resource scheduling; the scheduler is used for scheduling the wireless resources corresponding to the specified slice information.
In this embodiment of the present invention, determining a scheduler for scheduling radio resources and a resource block corresponding to the scheduler according to public land mobile network information and slice information is implemented by: determining a scheduling pool for scheduling the wireless resources and a resource pool corresponding to the scheduler according to the public land mobile network information; the scheduling pool determines a scheduler for scheduling the wireless resources according to the slice information; the resource pool acquires slice information from the scheduling pool, and establishes or determines a resource block corresponding to the scheduler according to the slice information; wherein the resource blocks correspond to physical resources having a specified purpose.
Further, the following steps are adopted to determine a scheduling pool for scheduling the radio resources and a resource pool corresponding to the scheduler according to the public land mobile network information: the scheduling manager establishes or determines a scheduling pool for scheduling the wireless resources according to the public land mobile network information; the resource manager acquires public land mobile network information from the scheduling manager, and establishes or determines a resource pool corresponding to the scheduling pool according to the public land mobile network information; wherein the resource pool corresponds to a radio resource of the designated public land mobile network.
In this embodiment of the present invention, the scheduler determines physical layer resources available for scheduling from the resource blocks and communicates with the physical layer to schedule the physical layer resources.
For example, a user sends a resource scheduling request through a terminal, and under the condition that the user does not feel, a scheduling manager obtains resource demand information from a CU, determines PLMN information and slice information corresponding to the resource demand information, and utilizes big data of a mobile operator to slice the data scheduling request, the scheduling manager determines a scheduling pool responsible for the mobile operator, and the resource manager obtains the resource demand information from the scheduling manager and determines a resource pool corresponding to the mobile operator in the resource pool. The further scheduling pool determines a scheduler corresponding to the mobile operator big data slice, and the resource block obtains resource demand information from the scheduler and determines a resource block corresponding to the mobile operator big data slice. The scheduler obtains appropriate resources from the corresponding resource blocks, the resource blocks input the allocated resource information into the resource collector, and at the end of TTI scheduling, a PDU (protocol data unit Protocol Data Unit) of UE (User Equipment) level is generated and issued to the PHY.
In another embodiment of the present invention, a scheduling pool, a resource pool, a scheduler, and resource blocks are also established and managed according to the scheduling request.
In this embodiment of the present invention, first resource requirement information including public land mobile network information is received before public land mobile network information and slice information of radio resources requested to be scheduled by a scheduling request are acquired; the scheduling manager establishes and manages a scheduling pool according to the first resource demand information; the resource manager obtains the first resource demand information from the scheduling manager, and establishes and manages a resource pool corresponding to the scheduling pool according to the first resource demand information.
In this embodiment of the invention, second resource requirement information including network slice information is also received; under the management of a scheduling manager, the scheduling pool establishes and manages the scheduler according to the second resource demand information; the resource pool acquires second resource demand information from the scheduling pool, and establishes and manages resource blocks corresponding to the scheduler according to the second resource demand information.
For example, the scheduling manager interacts with the CU to obtain resource demand information, such as: PLMN and slice related information, and establishing and managing a scheduling pool according to the acquired resource demand information, for example: and establishing, updating and deleting scheduling pools according to the resource demand information, wherein each scheduling pool corresponds to one PLMN.
The resource manager interacts with the scheduling manager, and obtains resource requirements from the scheduling manager to perform corresponding resource pool management, for example: establishing a corresponding resource pool for the scheduling pool, and managing the established resource pool, for example: and updating and deleting the corresponding resource pool according to the resource demand information.
Each scheduling pool corresponds to a scheduling requirement of a PLMN level, and each scheduling pool can be associated with a plurality of resource pools, so that resource sharing in a network sharing mode is realized. The scheduling pool and the corresponding scheduling manager of the previous layer have interfaces, and the interfaces are mainly responsible for feeding back the demand of the scheduling pool on the resource pool and receiving the service demand of the scheduling manager, for example: updating scheduling policies, etc. The scheduling pool is responsible for managing the scheduler according to the resource demand information, for example: and establishing, deleting and updating the scheduler according to the resource demand information.
In addition, a communication interface is configured between the scheduling pool and the corresponding resource pool, and the interface is mainly responsible for interacting with the corresponding resource pool according to the resource block requirement of the scheduler, and the resource pool establishes, updates or deletes the resource block according to the resource block requirement. Each resource pool corresponds to a PLMN level resource for managing the resources of the PLMN-available portion.
Each scheduler is responsible for scheduling requirements at a slice level, and is divided into a downlink scheduler and an uplink scheduler, and one scheduler can be associated with a plurality of resource blocks.
Additional details of this embodiment of the present invention may be referred to in the detailed description of fig. 1, and will not be described herein.
Based on the technical solutions of the above embodiments of the present invention, the requirement of network sharing and slicing is introduced in the 5G network, where network sharing refers to that one RAN (Radio Access Network ) may be connected to a plurality of operator core network nodes, the RAN may be co-constructed by a plurality of operators, or one of the operators may separately construct the RAN, and the other operators lease the RAN network of the operator. The network slice may be treated differently according to the requirements of each customer, for example: a high speed channel network slice, a big data network slice, etc. may be provided. By means of the slicing, different traffic differentiation processes and resources can be isolated, and then the mobile network operator can treat the clients as clients belonging to different tenant types, each client having different service requirements, which are managed and subscribed according to what slice type each tenant can use according to SLA (Service Level Agreement ). Therefore, each scheduling pool or each scheduler can independently perform thread deployment, so that the scheduling pressure of each TTI can be dispersed in a mode of deploying different scheduling pools or schedulers to different threads, and the parallelism of the scheduling process is improved. Therefore, different network sharing modes and scheduling requirements of different network slices are clearly supported, and the expandability of a scheduling architecture is effectively enhanced. Meanwhile, the scheduling process can be selectively separated in the second layer or the third layer and deployed on different concurrent threads, so that the scheduling processing capacity is effectively improved, the scheduling response time is obviously reduced, and the user experience is improved.

Therefore, through the three-layer wireless resource scheduling architecture, efficient wireless resource scheduling is realized according to the resource demand information, meanwhile, the bottom layer of schedulers can be configured according to the functions of physical resources, and each scheduler is responsible for scheduling the physical resources with a specific function. Therefore, the parallel processing capacity of the scheduling process of the wireless resources is remarkably improved, the scheduling processing speed is effectively improved, and the user experience is remarkably improved.
