Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, unless explicitly stated and limited otherwise, the terms "mounted," "disposed," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.
In the prior art, when configuring hardware resources for a newly-built cell, proper hardware resources are often selected in a manual selection mode according to experience of staff and comprehensively considering equipment cost. The method for selecting the hardware resources has large granularity, and because of the lack of quantitative calculation of specific processing capacity of the hardware resources, the selected hardware resources often have the phenomenon of mismatching with service operation in a cell needing to be established. For example, there may be a situation where the service operation in the newly built cell is not fully supported, or there may be a situation where hardware resources are excessive. Under the condition of excessive hardware resources, the waste of the hardware resources is caused, so that the whole processable business volume of the hardware resources is lower, and under the condition of insufficient hardware resources, the hardware resources are added later, and the normal business operation is easily influenced.
Based on the research findings, the embodiment of the application provides a hardware resource scheduling scheme, and by pre-establishing the mapping relation between the cell service operation and the hardware resources, the required hardware resource data can be accurately calculated when a cell is newly built, so that reasonable and effective management of the hardware resources is realized, and the processable traffic of the hardware resources is improved.
Referring to fig. 1, fig. 1 is an application scenario schematic diagram of a hardware resource scheduling method according to an embodiment of the present application. Included in this scenario is a wireless communication system that includes a hardware resource scheduling device, such as a base station device 100, which base station device 100 may be responsible for controlling a plurality of cells. The wireless communication system further comprises a user equipment 200, and the user equipment 200 can access the base station device 100 through a network to realize user service operation, wherein the user equipment 200 is a wireless communication terminal, such as a portable telephone or a smart phone.
Referring to fig. 2, fig. 2 is a flowchart of a hardware resource scheduling method applied to the base station apparatus 100 shown in fig. 1, and each step included in the method will be described in detail below.
Step S110, receiving a resource scheduling instruction, wherein the resource scheduling instruction comprises cell specification information to be established.
Step S120, according to the relation between the specification of the cell to be established and the specification of the preconfigured unit cell and the preset baseline hardware resource, obtaining the hardware resource scheduling data corresponding to the cell to be established, wherein the baseline hardware resource is the hardware resource corresponding to supporting the user service and the public service operation in the preconfigured unit cell specification.
The base station apparatus 100 needs to allocate hardware resources for supporting the intra-cell service operation first when being responsible for controlling the cell operation. Hardware resources with processing capability, storage capability, or forwarding capability related to the base station device 100 generally include components such as a CPU chip, a DSP chip, a switch chip, a PCIe interface bus, a network port/optical port module, a memory chip, and a Radio Frequency (RF). The hardware resources can be classified into processing type hardware resources, forwarding type hardware resources and storage type hardware resources according to the different capabilities of the hardware resources. For example, the processing type hardware resources mainly include a CPU chip, a DSP chip, and the like. The forwarding type hardware resources mainly comprise a switching chip, a PCIe interface bus and a network port/optical port module. Whereas the memory type hardware resources mainly include memory chips.
In this embodiment, a quantization manner may be adopted in advance to obtain a baseline hardware resource capable of supporting user service and public service operation in a preset unit cell specification. The unit cell specification information mainly comprises information such as the number of users accessed in a cell, frequency bands and the like. For example, the unit cell specifications as listed in table 1 may be, for example, a cell with a frequency band of 20MHz and a number of access users of 300 users, a cell with a frequency band of 10MHz and a number of access users of 200 users, or the like, and the unit cell is not particularly limited.
TABLE 1 Unit cell Specification information
| Frequency band | Number of users | |
| Unit cell 1 | 20MHz | 300 pieces |
| Unit cell 2 | |
200 |
In this embodiment, the core sub-resources of each type of hardware resource are used for quantization processing of processing capacity, where the core sub-resources of each type of hardware resource refer to resources in each type of hardware resource that have a greater influence on service operation, and in this embodiment, a CPU chip, a DSP chip, and a memory chip are used as an example for illustration. The core sub-resources of the CPU chip mainly comprise main frequency, external frequency, frequency multiplication coefficient, L2 cache size, kernel number and the like. The core sub-resources of the DSP chip mainly comprise main frequency, core number, instruction period, multiply-accumulate time, FFT fast Fourier transform processing time, cache size and the like. The core sub-resources of the memory chip mainly comprise frequency, rate, capacity and the like.
Alternatively, core sub-resources and business capabilities associated with the computational capabilities of the hardware resources may be mapped in an approximately quantitative manner. For example, the core sub-resource related to the computing capability of the CPU may be expressed in a set form in advance, and is denoted as a core sub-resource set pcpu= { main frequency, cache, number of cores }, and the core sub-resource related to the computing capability of the DSP may be expressed in a set form, and is denoted as a core sub-resource set pdsp= { main frequency, cache, number of cores }, of the DSP. Similarly, the core sub-resource related to the computing capability of the memory chip is expressed in a set form, and is denoted as a memory hardware core sub-resource set pmem= { frequency, rate, capacity }. The core sub-resource of the overall hardware of the base station apparatus 100 may be expressed as p= { Pcpu, pdsp, pmem }.
It should be noted that the above determination of the core sub-resource in the hardware resources of the base station device 100 is merely illustrative, and other resources of each type of hardware resources may be selected as the core sub-resource according to the requirements in practical applications, which is not particularly limited.
Referring to fig. 3, in this embodiment, baseline hardware resources that can be used to support user services and public service operations of unit cell specifications may be preconfigured by:
step S101, obtaining the number of the processing type hardware resources, the forwarding type hardware resources and the core sub-resources in the storage type hardware resources for supporting the operation of user services and public services in a unit cell according to the number of pre-access users in the unit cell and the required frequency band.
Step S102, the base line hardware resource is obtained according to the number configuration of the processing type hardware resource, the forwarding type hardware resource and the core sub-resource in the storage type hardware resource.
Alternatively, a unit cell, for example, one 20MHz cell, 10MHz cell, or 2 20MHz cells, etc., is preset. Setting the pre-access user number of the unit cell, the required frequency band and the like to obtain various hardware resources supporting the service operation in the unit cell. The hardware resource needed by the unit cell is a baseline hardware resource Pbaecell, and the hardware resource is composed of a CPU baseline hardware resource Pcpu-basecell, a DSP baseline hardware resource Pdsp-basecell and a storage baseline hardware resource Pem-basecell, and is expressed as Pbaecell= { Pcpu-basecell, pdsp-basecell, pem-basecell }. The baseline hardware resource is a corresponding hardware resource supporting the operation of user service and public service in a preconfigured unit cell specification, and the corresponding hardware resource can be the minimum resource capable of supporting the operation of the unit cell service, can be a hardware resource formed by adding a certain amount of resources on the basis of the minimum resource capable of supporting the operation of the unit cell service, or can be a hardware resource corresponding to the operation of the unit cell service obtained by setting according to actual requirements.
Optionally, the number of core sub-resources of each type of hardware resource required by the operation of the unit cell is obtained in advance through a simulation operation mode, for example, when the unit cell is 2 20MHz cells, the number of core sub-resources of a CPU chip supporting the operation of the user service and the public service in the unit cell is Pcpu-basecell= {1.6ghz,4m,1/16}. The number of core sub-resources of the DSP chip supporting the user service and the public service in the unit cell is Pcpu-basecell= {800MHz,8M,1/18}. The number of core sub-resources of the memory chip supporting the user service and the public service operation in the unit cell is Pcpu-basecell= {2133MHz,160 MT/s,2G/32G }.
The above set means that the base station needs to occupy 1 core resource of the main frequency 1.6GHz,4M cache and 16 core CPU under the condition of running 2 20MHz cells; 1 core resource of the 18-core DSP needs to occupy the main frequency of 800MHz and 8M cache; and occupies 2G memory space. Through the conversion of the hardware processing resources and the storage resources into the operation capability, the processing capability of the service is converted into the occupation number of the cores of the hardware core resources and the occupation of the memory capacity under the same main frequency and cache.
After the base line hardware resource corresponding to the unit cell is established through the steps, when the resource scheduling instruction is received, the hardware resource scheduling data corresponding to the cell to be established can be obtained according to the relation between the cell specification to be established and the specification of the unit cell in the resource scheduling instruction and the base line hardware resource corresponding to the unit cell. The cell to be established is the cell which is currently pre-established but is not established successfully.
For example, in the case where the unit cell is 2X MHz cells, where X may be 5, 10, 15, 20, etc. The hardware resource scheduling data corresponding to the n cells to be established can be obtained through calculation according to the following formula:
pcelln= ((n+1)/2) Pbasecell (n is an odd number)
Pcelln= (n/2) Pbasecell (n is even)
Wherein Pcelln is the hardware resource scheduling data corresponding to the cells to be established, pbascell is the baseline hardware resource corresponding to the unit cell, and n is the number of the cells to be established.
For example, when the cell to be established is 4X MHz cells, the hardware resources required to be allocated are: pcell4=2×Pbascell= {2×Pcpu-basecell,2×Pdsp-basecell,2×Pmem-basecell }, that is, 2 CPU core resources and 2 DSP core resources and 4G memory capacity are required.
Step S130, corresponding cell-level hardware resources are allocated to the cell to be established according to the obtained hardware resource scheduling data.
After the hardware resource scheduling data corresponding to the cell to be established is obtained through the above steps, the corresponding cell-level hardware resource can be allocated to the cell to be established from the hardware resources of the base station device 100. The cell-level hardware resource can support the operation of the user service and the public service in the cell to be established.
In this embodiment, the cell is carried on the cell-level hardware resource, and the mapping relationship between the user service and the public service operation and the required cell-level hardware resource can be established through the concept of the cell. The cell-level hardware resources correspond to cells of the logical concept, which can be quantized to physical resources. In order to reasonably utilize the cell-level hardware resources to support the access of the user terminal and support the operation of user services, the user services and the public service processing capacity of the cell-level hardware resources are quantized and then correspond to a plurality of physical resource blocks, and the cell-level hardware resources corresponding to each physical resource block support the operation of the corresponding user services and public services. Different service demand information and the physical resource blocks required to be occupied can be established in advance, so that the number of the physical resource blocks required to be occupied by a user can be calculated when the user is pre-accessed, and reasonable control and scheduling of cell-level hardware resources are realized.
For example, a cell corresponding to a cell-level hardware resource supporting one 20MHz cell operation may be divided into 100 physical resource blocks, where assuming that 10 physical resource blocks are required for common service operation in the cell, the remaining 90 physical resource blocks may be used for user service operation.
In this embodiment, the correspondence between the service requirement information and the physical resource blocks to be occupied as shown in the following table may be pre-established:
table 2 correspondence table of service demand information and physical resource blocks to be occupied
Wherein QCI (QoS Class Identifier) is a scale value for measuring packet forwarding behavior, such as packet loss rate, packet delay budget, for a particular offered service data flow, which is applied to both guaranteed bit rate (Guranteed Bit Rate, GBR) traffic bearers and Non-guaranteed bit rate (Non-Guranteed Bit Rate, non-GBR) traffic bearers, for specifying control bearer group packet forwarding modes defined within the access node, such as scheduling weights, admission thresholds, queue management thresholds, link layer protocol configurations, etc. PRB (Physical Resource Block ) is the physical resource block described above. The RAB is a radio access bearer (Radio Access Bearer).
The QCI is defined as 1-4 for GBR bearer traffic and the QCI is defined as 5-9 for Non-GBR bearer traffic.
For GBR bearer service (QCI: 1-4), the number of PRBs corresponding to the occupied cell-level hardware resources is Urb= ((RAB. DataRate)/64)/2;
for a no-GBR bearer (QCI: 5-9), the number of PRBs corresponding to the occupied cell-level hardware resources is up-no= ((RAB) dataRate)/64)/8;
physical resource block occupied by User 1: urb1+Urb1-no 1;
physical resource blocks occupied by User 2: uprb2+uprb-no2;
physical resource block occupied by User 3: uprb3+uprb-no3;
……
physical resource blocks occupied by users UserN: upprbN+Upbb-noN.
If N users are accessed to a certain cell at present, the physical resource blocks occupied by the users are recorded as follows: utotalbb=uprb1+uprb1+uprb2+uprb2+ … +uprbn+uprb-noN.
After the corresponding relation between the service requirement information and the physical resource blocks to be occupied is pre-established and stored through the above steps, referring to fig. 4, when a user pre-accesses the base station device 100, user-level resources may be allocated to the user according to the following steps:
step S210, when an access request of a user is monitored, the access request carries service demand information of the user, and the number of physical resource blocks required to be occupied by the user is obtained according to the service demand information of the user based on the corresponding relation between the pre-stored service demand information and the physical resource blocks required to be occupied.
Step S220, corresponding physical resource blocks are allocated to the user according to the number of the physical resource blocks required to be occupied by the user.
As described above, the base station apparatus 100 may be responsible for managing a plurality of cells, and may allocate corresponding cell-level hardware resources to the plurality of cells. In this embodiment, when an access request of a user is monitored, a target cell pre-accessed by the user may also be obtained, where the access request of the user is sent by the corresponding user terminal 200. When the corresponding physical resource blocks are allocated to the user, whether the number of the physical resource blocks which can be allocated to the target cell and are to be accessed by the user can meet the requirement of the user is also detected.
Optionally, based on the corresponding relation between the pre-established service requirement information and the physical resource blocks required to be occupied, the number of the physical resource blocks required to be occupied by the user can be obtained according to the service requirement information of the user to be accessed.
And when the number of the physical resource blocks which can be allocated to the target cell and are to be accessed by the user is smaller than the number of the physical resource blocks required by the user, detecting whether other built cells which have the allocated free physical resource blocks except the target cell exist. The target cell is the cell to which the current user wants to access. If there are other established cells with allocable idle physical resources, the user to be accessed needs to be scheduled to the other established cells, wherein the established cells are the cells which are established successfully at present.
For example, if the target cell to be accessed has 90 physical resource blocks available for allocation to support user service operation. And if the sum of the number of the physical resource blocks required to be occupied by the current user to be accessed and the number of the occupied physical resource blocks in the target cell to be accessed exceeds 90, the cell to be accessed does not have the physical resource blocks capable of meeting the user service operation of the user to be accessed, and the user to be accessed needs to be scheduled to other cells.
And allocating corresponding physical resource blocks for the user to be accessed from the physical resource blocks of other established cells with the allocatable idle physical resource blocks according to the number of the physical resource blocks required to be occupied by the user to be accessed.
After the cell is established, the cell needs to be activated, and the cell in an activated state can allocate corresponding user-level resources for the user to be accessed.
Therefore, when the cell to be accessed does not have the physical resource block which can meet the user service operation of the user to be accessed, the physical resource block can be allocated for the user to be accessed from other cells which have idle physical resource blocks and are in an activated state.
Of course, if the number of physical resource blocks available for allocation of the target cell to be accessed by the user is greater than or equal to the number of physical resource blocks required by the user, allocating corresponding physical resource blocks for the user from the physical resource blocks of the target cell to be accessed according to the number of physical resource blocks required to be occupied by the user.
The above is that in case there are other established cells with allocable free physical resource blocks, the problem of user access can be solved by scheduling the users to other established cells. However, when the number of physical resource blocks available for allocation of the target cell to be accessed by the user is smaller than the number of physical resource blocks required by the user and there are no other established cells other than the target cell with allocable free physical resource blocks, the user access problem can be solved by adopting a new cell mode.
When the base station device 100 obtains the new resource scheduling instruction, the corresponding cell-level hardware resource is allocated to the newly-established cell in the new resource scheduling instruction by adopting the mode of allocating the cell-level hardware resource. And allocating corresponding physical resource blocks for the user from the idle physical resource blocks of the newly-built cell corresponding to the new resource scheduling instruction according to the number of the physical resource blocks required to be occupied by the user.
It should be understood that, the base station apparatus 100 has limited hardware resources, and when the number of physical resource blocks available for allocation of the target cell to be accessed by the user is smaller than the number of physical resource blocks required by the user, and there are no other established cells other than the target cell with allocable idle physical resource blocks, and there are no cell-level hardware resources available for allocation to the newly established cell, then the problem of user access needs to be solved by adopting a resource preemption manner.
Alternatively, the priority of the user to be accessed may be obtained, in this embodiment, different priorities may be set in advance for different service types, for example, a service with strong real-time performance such as a call type, a video type, etc. may be set as a higher priority, and a service with information query, search, etc. may be set as a lower priority. Optionally, the priority of the user to be accessed is obtained according to the service type of the user to be accessed.
Optionally, the priority of the accessed user in the cell to be accessed by the user is obtained, in this embodiment, when each user accesses the cell resource, the base station device 100 may record the access information of the user, for example, may record as userctxnfoslist= { RNTI, pri, uprb-no, activetime, isBusy }, where RNTI (RNTI Radio Network Tempory Identity) is a radio network temporary identifier, pri may be used to identify the priority of the corresponding user, uprb and Uprb-no respectively represent the number of physical resource blocks occupied by the GBR bearer service and the no-GBR bearer service that need to be established by the corresponding user, activetime represents the time information of the corresponding user accessing the cell resource, and isBusy describes whether the service state of the user is a busy state.
In this embodiment, the priority of the accessed user may be obtained through the access information of the accessed user. And searching users with priority lower than that of the pre-accessed users in the accessed users, and taking the accessed users as target users.
Optionally, whether the target user meets a preset preempted condition or not may be detected, if yes, the physical resource blocks occupied by the target user are recovered, and corresponding physical resource blocks are allocated to the user from the recovered physical resource blocks according to the number of the physical resource blocks required to be occupied by the user.
In this embodiment, whether the target user satisfies a preset preempted condition may be detected by: and detecting whether the activation time of the target user is longer, for example, detecting whether the time length of the activation time from the current moment exceeds a preset time length, and if so, performing subsequent detection. Or when the number of the target users is multiple, that is, the priorities of the multiple target users are the same and lower than the priority of the pre-accessed user, the user with the longest duration of the corresponding activation time from the current moment can be selected from the multiple target users, and then the selected target user is subjected to subsequent detection.
Optionally, detecting whether the service state of the target user meeting the above requirements is in an idle state, if so, detecting whether both up rb and up rb-no in the access information of the target user are greater than the number of physical resource blocks occupied by the user to be accessed to establish the GBR bearer service and the no-GBR bearer service. If the conditions are met, the target user can be judged to meet the preset preempted conditions, the physical resource blocks occupied by the target user can be recovered, and corresponding physical resource blocks are allocated for the users to be accessed.
Optionally, in this embodiment, when the physical resource block is recovered, the target user may be one, that is, when a certain target user meets the above condition, the physical resource block of the target user is recovered to meet the access requirement of the user to be accessed. However, if there are no physical resource blocks occupied by a single target user and the number of the physical resource blocks is greater than or equal to the number of physical resource blocks required by the user to be accessed, that is, there are a plurality of target users with priority lower than that of the user to be accessed, and the sum of the physical resource blocks occupied by the plurality of target users is greater than or equal to the number of the physical resource blocks required by the user to be accessed, the access problem of the user can be solved by recovering the physical resource blocks occupied by the plurality of target users and allocating the physical resource blocks to the user to be accessed.
In this embodiment, when a user accessing a cell resource releases or a service of the user initiates a change to cause a change of a physical resource block of a cell carried by a cell-level hardware resource, dynamic recovery management needs to be performed on the physical resource block of the cell-level hardware resource. I.e. the number of current occupied physical resource blocks is equal to the number of occupied physical resource blocks in the cell before the user releases or before the user's traffic initiates a change minus the physical resource blocks released by the user or the reduced occupied physical resource blocks due to the user's traffic change. Thus, the dynamic management of the physical resource blocks of the cell-level hardware resources is realized.
Further, in order to dynamically allocate the cell-level hardware resources and avoid the waste of power consumption of the hardware resources, referring to fig. 5, in this embodiment, the method further includes the following steps:
step S310, detecting whether there is a cell not allocated with a physical resource block to the user, and if there is a cell not allocated with a physical resource block to the user, executing step S320. If not, no operation is performed.
Step S320, detecting whether there are other established cells with free physical resource blocks in addition to the cell, and if there are other established cells with free physical resource blocks in addition to the cell, executing step S330. If not, no operation is performed.
Step S330, releasing the cell-level hardware resources corresponding to the cells which are not allocated with the physical resource blocks to the users.
Alternatively, in this embodiment, it may be detected in real time, or at intervals of a preset period, whether there is a cell to which no physical resource block is allocated to the user, that is, a cell to which no user accesses or no service is available for a long time. I.e. the situation that the cell-level hardware resource corresponding to the cell is idle, the cell has no user access or long-time useless service. In order to avoid useless power consumption waste of the cell-level hardware resources in this case, the cell-level hardware resources corresponding to the cell need to be released for the hardware resource allocation of the subsequent other newly-built cells.
In this embodiment, in order to ensure that there are other cells available for supporting user service operation or other cells available for supporting potential user access after the release of the above-mentioned cell-level hardware resources, before the release of the above-mentioned cell-level hardware resources, it is further required to detect whether there are other established cells with idle physical resource blocks in addition to the above-mentioned cells, and the established cells are in an active state. If so, the step of releasing the cell-level hardware resources described above may be performed.
