In order to facilitate understanding of the technical solutions provided by the embodiments of the present application by those skilled in the art, the following briefly describes related technologies:

at present, in the application scene of a private network, video transmission operation (such as VR video transmission operation, non-VR video transmission operation, VR game and other interactive operation) has extremely high requirements on network transmission, generally requires a video stream code rate of tens Mbps, and the transmission delay is within 20 milliseconds; because the 5G private network can provide a high-bandwidth low-latency network environment, the 5G private network has the opportunity to meet the network requirements of video streaming.

For the existing 5G base station, when the resource scheduler is used for performing the resource scheduling operation, the granularity of control for scheduling the base station resources is too coarse, for example: for each 5G frame, the base station provides time-frequency resources for each user according to a specific proportion (for example: 20%, 30%, etc.), in this implementation manner, only the specific resource proportion can be configured, and a specific time Slot resource Slot cannot be adjusted, that is, a finer granularity resource regulation operation cannot be performed; in general, the related art cannot perform fine resource regulation and control operations, so that the time-frequency resources of the base station cannot be fully and fully utilized, and the utilization rate of the time-frequency resources is reduced.

In order to solve the above technical problem, this embodiment provides a method, an apparatus, and a system for controlling a private network base station, where an execution body of the method for controlling a private network base station is a control system for a private network base station, and the control system may include: the remote controller and the private network base station which is in communication connection with the remote controller can be obtained by expanding the radio access network intelligent control RIC standard, specifically, the remote controller can expand a coarse-granularity control service model interface in the RIC standard into a new fine-granularity control service model interface, the remote controller is provided with an RIC-SDK module, the private network base station is provided with an RIC proxy module which is in communication connection with the RIC-SDK module, so that the remote controller can be in communication connection with the private network base station through the RIC-SDK module and the RIC proxy module, the remote controller can generate fine-granularity time slot resource scheduling information and send the time slot resource scheduling information to the private network base station, thereby enabling the private network base station to obtain and execute a fine-granularity scheduling strategy, and further fully utilizing the time-frequency resources (or physical resources) of the private network base station.

The number of private network base stations to which the remote controller is in communication connection can be one or more; in particular, the remote controller may be any programmable computing device having the control capability of a private network base station, and further, the basic structure of the remote controller may include: at least one processor. The number of processors depends on the configuration and type of remote controller. The remote controller may also include Memory, which may be volatile, such as RAM, or nonvolatile, such as Read-Only Memory (ROM), flash Memory, etc., or both. The memory typically stores an Operating System (OS), one or more application programs, program data, and the like. In addition to the processing unit and the memory, the remote controller also includes some basic configurations, such as a network card chip, an IO bus, a display component, and some peripheral devices. Alternatively, some peripheral devices may include, for example, a keyboard, a mouse, a stylus, a printer, and the like. Other peripheral devices are well known in the art and are not described in detail herein.

In addition, the private network base station may be communicatively connected to one or more private network devices and servers to enable stable data processing operations, and the private network devices may be implemented as at least one of: VR clients, video clients, vehicle terminals, smart wearable devices, etc., network connections may be made between private network devices and private network base stations, which may be wireless or wired network connections. If the private network device is in communication connection with the private network base station, the network system of the mobile network may be any one of 4G (LTE), 4g+ (lte+), 5G, 5.5G, 6G, and the like.

Specifically, in order to stably implement efficient scheduling or control operation for the time-frequency resource of the private network base station, the remote controller and the private network base station in this embodiment may be respectively configured to perform the following steps:

and the remote controller is used for generating time slot resource scheduling information corresponding to the private network base station in a preset control period of the private network base station and transmitting the time slot resource scheduling information to the private network base station. Wherein, the remote controller may include: a quality of service cross-layer scheduling module, a capability & demand prediction module, a peripheral device, which may include at least one of: the cross-layer user ID matching module, the subtle-level time synchronization module and the like, because the operation of the remote controller involves various cross-layer indexes, in order to avoid system overhead and inconsistency caused by multiple transmission of the same data, the cross-layer scheduling module, the capacity & demand prediction module and the peripheral equipment of the service quality can be in communication connection with a cross-layer message bus, the cross-layer message bus is in communication connection with a issuing control module and a collecting control module, and the cross-layer message bus can adopt a message queue middleware in a classical publish-subscribe mode. Specifically, each module is used for executing the following steps:

The system comprises a collection control module, a service quality cross-layer scheduling module and a time slot resource scheduling module, wherein the collection control module is used for collecting and acquiring resource related parameters corresponding to a private network base station, wherein the resource related parameters can comprise resource use information, current to-be-processed data corresponding to the private network base station, base station capability provided by the private network base station and the like, and the collected resource related parameters can be sent to the service quality cross-layer scheduling module through a cross-layer message bus so as to be used for determining time slot resource scheduling information.

The capacity & demand prediction module is used for predicting the private network base station capacity and the transmission demand in the next control period, obtaining the private network base station capacity and the transmission demand in the next control period, and sending the predicted private network base station capacity and transmission demand in the next control period to the service quality cross-layer scheduling module through the cross-layer message bus.

The capability & demand prediction module stores capability and demand prediction algorithms, which can be used to predict private network base station capability (network transmission capability) and transmission demand in a next control period, and for the private network base station capability in the next control period, the capability & demand prediction module can be obtained by analyzing and processing physical layer information and data link layer information of the private network base station, and specifically, the prediction principle of the network transmission capability of the private network base station can be as follows: and performing channel quality estimation operation on a physical downlink shared channel (Physical Downlink Shared Channel, abbreviated as PDSCH) to confirm the upper limit value of a Modulation and Coding Strategy (MCS) which can be adopted by each terminal equipment (UE) in the next control period, and then predicting the capability of a private network base station for transmitting data to each UE based on the upper limit value of the MCS.

The transmission requirement of the private network base station in the next control period can be obtained by analyzing and processing the information of the application layer and the transmission layer of the private network base station, wherein the prediction principle of the transmission requirement can be as follows: acquiring the type (such as I frame and P frame) of a historical transmission frame (such as video frame and image frame) and the size of a transmission frame data packet through a private network base station; and then, the transmission requirement of the next preset control period can be predicted based on the type of the historical transmission frame and the size of the transmission frame data packet, so as to obtain a predicted transmission requirement, wherein the predicted transmission requirement comprises the type of each transmission frame and the upper limit value of the transmission frame data packet size. Specifically, taking an application scenario of video transmission as an example, a linear regression method can be used to predict the time of possibly reaching a new video frame data packet in a next control period based on the arrival time of a historical video frame data packet, predict the type of each video frame according to the type of the historical video frame reported by an application layer and the size of the video frame data packet reported by a base station, and infer the upper limit value of the size of the data packet, thereby completing the prediction operation of the transmission requirement. In summary, in order to timely perform the operation of generating the time slot resource scheduling information, the capability & demand prediction module may use some fast and efficient prediction algorithms to perform the fast prediction operation on the network transmission capability and the transmission demand.

The cross-layer user ID matching module is used for constructing and maintaining the mapping relation among the temporary identification information, the session tunnel identification and the IP address; specifically, the cross-layer user ID matching module can acquire a temporary identifier information-free RNTI of the terminal equipment in the private network base station and a first mapping relation between the temporary identifier information RNTI and the session tunnel ID through the private network base station; determining a second mapping relation between the IP address and the session tunnel ID corresponding to the terminal equipment; and generating the mapping relation among the temporary identification information, the session tunnel identification and the IP address based on the first mapping relation and the second mapping relation. Specifically, since the application layer uses an IP address as a unique UE-ID and the private network base station RAN uses an RNTI as a unique ID, in order to prevent confusion between UE-IDs of different layers, a 5GC core network can be utilized as a bridge for mapping them. In a 5GC core network, a session management function records a first mapping relation between RNTI reported by a private network base station RAN and PDU session tunnel ID (TEID), acquires a second mapping relation between TEID and IP address pre-stored in a database, constructs a translation chain RNTI-TEID-IP address to associate different UE-IDs through the first mapping relation and the second mapping relation, and distributes corresponding base station resources for each terminal device through the constructed translation chain so as to ensure stable data processing.

The time synchronization module is used for realizing time synchronization operation between the private network base station and the remote controller, and particularly, the time synchronization module can realize subtle-level time synchronization operation, and because the time error required by fine-granularity scheduling operation at the time slot level is far smaller than 5G time slot time of 500us, the accurate time protocol (PTP) level synchronization operation is provided between the private network base station and the remote controller through a pair of intelligent NICs.

And the service quality cross-layer scheduling module is used for acquiring the parameters such as the resource related parameters for carrying out resource scheduling operation, the predicted private network base station capability and the data transmission requirement and the like, and analyzing and processing the parameters such as the resource related parameters, the predicted private network base station capability and the data transmission requirement and the like so as to determine the time slot resource scheduling information corresponding to the private network base station. The service quality cross-layer scheduling module includes a scheduling policy for generating resource scheduling information, where the scheduling policy is related to a specific environment of system deployment and a specific execution application, and a person skilled in the art can flexibly adjust or deploy the specific scheduling policy according to the specific environment of system deployment and the specific execution application, which is not described herein.

In addition, the obtained slot resource scheduling information may include: the length of the time slot scheduling list is equal to the length of the control period, and the time slot scheduling list may include temporary identification information, a code modulation strategy and the number of physical resource blocks corresponding to each terminal device, for example: the time slot scheduling list may be implemented as { RNTI, MCS, PRB }, where RNTI is a unique but temporary ID of a terminal device UE called a radio network temporary identity in a private network base station RAN, MCS is a coded modulation policy selected by the RAN for the UE, and PRB is the number of material resource blocks allocated by the private network base station RAN for the UE. For example, the time slot resource scheduling information obtained by the qos cross-layer scheduling module may be: { Timestamp, frame_id, { slot_id [ { RNTI, MCS, PRB },.+ -,...

In addition, for the time slot resource scheduling information, in order to ensure that the remote controller can control the resource scheduling operation of the private network base station without failure under the condition that the remote controller has communication delay with the private network base station, when the resource scheduling information is generated based on the remote controller, a certain time sequence design is required to be satisfied, and because the specific time sequence design can be used for measuring the effectiveness and success rate of cross-layer scheduling, for example: because of time delay of information reporting and the like of the base station, the remote controller hopes to delay the time for generating the time slot resource scheduling information as much as possible so as to obtain more timely information, thereby completing more accurate prediction and generating a more efficient scheduling strategy; on the other hand, it is necessary to ensure that the scheduling policy for each control period can reach the private network base station in time before expiration. Therefore, in order to perform scheduling operation on the timeslot resources of the private network base station timely and accurately, the embodiment configures the remote operation time sequence for the remote controller, specifically, the service quality cross-layer scheduling module may perform the expected execution time of the timeslot resource scheduling operation through the private network base station, acquire the information generation duration and the information transmission duration corresponding to the timeslot resource scheduling information, and determine the generation time of the timeslot resource scheduling information based on the expected execution time, the information generation duration and the information transmission duration, that is, the generation time=the expected execution time-the information generation duration-the information transmission duration, and then enable the service quality cross-layer scheduling module to generate the timeslot resource scheduling information corresponding to the private network base station at the generation time.

When the time slot resource scheduling information is generated based on the generation time, the service quality cross-layer scheduling module can delay the time for generating the time slot resource scheduling information as much as possible, and the scheduling strategy of each control period can be ensured to reach the private network base station in time before expiration, so that the private network base station can obtain the more timely time slot resource scheduling information, thereby completing more accurate resource scheduling control operation and being beneficial to improving the effectiveness and success rate of cross-layer scheduling.

And the private network base station is used for receiving the time slot resource scheduling information sent by the remote controller and scheduling the time slot resources of the private network base station based on the time slot resource scheduling information. The private network base station comprises a local adapter and a RIC agent module, wherein the local adapter and the RIC agent module can be used for executing the following steps:

the RIC agent module is used for detecting the validity of the time slot resource scheduling information after receiving the time slot resource scheduling information with fine granularity, and obtaining first detection information corresponding to the time slot resource scheduling information; timely detecting the time slot resource scheduling information to obtain second detection information corresponding to the time slot resource scheduling information; target detection information corresponding to the slot resource scheduling information is determined based on the first detection information and the second detection information.

Wherein, performing validity detection on the time slot resource scheduling information, and obtaining first detection information corresponding to the time slot resource scheduling information may include: carrying out serialization processing on the time slot resource scheduling information to obtain a byte sequence corresponding to the time slot resource scheduling information; detecting whether the byte sequence is continuous; when the byte sequence is continuous, determining the first detection information as detection information for identifying that the time slot resource scheduling information is effective; when the byte sequence is discontinuous, the first detection information is determined to be the detection information for identifying that the time slot resource scheduling information is invalid.

The performing timeliness detection on the time slot resource scheduling information, and obtaining second detection information corresponding to the time slot resource scheduling information may include: acquiring a time stamp corresponding to the time slot resource scheduling information and the local synchronization time of the private network base station; and detecting timeliness of the time slot resource scheduling information based on the time stamp and the local synchronous time, and obtaining second detection information corresponding to the time slot resource scheduling information. Wherein. The step of detecting timeliness of the time slot resource scheduling information based on the time stamp and the local synchronization time, and the step of obtaining second detection information corresponding to the time slot resource scheduling information may specifically include: when the time stamp is the same as the local synchronous time, determining the second detection information as detection information for identifying timeliness of the time slot resource scheduling information; and when the time stamp is different from the local synchronous time, determining the second detection information as detection information for identifying that the time slot resource scheduling information does not have timeliness.

Specifically, after receiving the fine-grained time slot resource scheduling information and verifying the integrity and the validity of the time slot resource scheduling information, if the time slot resource scheduling information is timely and complete, the RIC proxy module may allow the base station resource to be scheduled based on the time slot resource scheduling information; when the time slot resource scheduling information is not timely or complete, the RIC proxy module can prohibit the scheduling operation of the resources of the base station based on the time slot resource scheduling information, and can discard or ignore the obtained time slot resource scheduling information.

The local adapter is configured to determine how to allocate a corresponding resource block to the terminal device UE for each time slot resource, and in the allocation process of the resource block, the PRB allocation information provided by the time slot resource scheduling information may cause non-optimal utilization operation of the available resources in the private network base station due to two reasons: (1) Data transmission relies on control resource allocation operations that may fail when multiple users contend for the same control resource element; for example, the UE relies on a set of resource blocks named control channel elements CCEs, including such things as: scheduling details, power control information and transmission information such as hybrid automatic repeat request, HARQ, feedback information. In each slot, only a few CCEs are available, so that when the number of terminal devices UE is multiple, a collision may occur when multiple UEs are hashed into the same CCE index in one slot, so that scheduling resources for multiple users in one slot is not always possible. (2) If the RLC buffer of a particular terminal equipment UE is empty, the resource blocks allocated for that UE may be wasted. In order to solve the above problem, the local adapter may ensure collision-free resource block allocation self-timer by correctly allocating control resources, and optimize the utilization of resources by adjusting the transmission sequence of the UE.

Specifically, the local adapter can realize conflict-free resource allocation operation, and in the process of establishing connection between the terminal equipment and the private network base station, the local adapter can acquire a random temporary identifier randomly generated for the terminal equipment; determining a temporary identifier configuration table for processing the random temporary identifier, wherein the temporary identifier configuration table comprises a plurality of predefined temporary identifiers without resource allocation conflict; the random temporary identifier is replaced by any predefined temporary identifier in the temporary identifier configuration table, and the predefined temporary identifiers replaced by different terminal devices are different.

In order to avoid mapping multiple UEs to the same CCE index, the local adapter may store predefined UE-RNTI configuration information (i.e. corresponding to the above-mentioned temporary identity configuration table, where one temporary identity configuration table may include 10 or 20 mapping relations), and in particular, a set of UE-RNTI configurations that do not cause CCE collisions may be calculated in an offline manner, and in a random access procedure in which the UE tries to establish a connection, the original randomly generated RNTI configuration may be replaced with a predefined RNTI configuration, i.e. any one of the predefined UE-RNTI configuration information, which implementation requires only a few lines of codes, which implementation is simple and reliable, and is practical for avoiding resource allocation collisions in the dedicated 5G network.

In other examples, the local adapter may not only implement the conflict-free resource allocation operation, but also implement the resource allocation adjustment, specifically, referring to fig. 2, the local adapter may obtain a resource linked list corresponding to the time slot resource scheduling information, where the resource linked list includes a plurality of ordered linked list nodes, and each linked list node includes a resource block that needs to be allocated for one time slot scheduling operation, and a modulation coding policy for identifying an amount of data that can be transmitted by each time slot resource; and scheduling the time slot resources of the private network base station based on the resource linked list.

When the local adapter performs scheduling operation on the time slot resources of the private network base station based on the resource linked list, the local adapter is used for: determining a current linked list node to be processed based on the resource linked list; when the private network base station has residual resource blocks, identifying whether the current list node corresponds to transmission data or not; and when the current list node corresponds to the transmission data, prohibiting the allocation operation of the time slot resources based on the current list node. The local adapter in this embodiment is also used to: acquiring life cycles corresponding to all chain table nodes in a resource chain table; and managing the corresponding linked list nodes based on the life cycle.

When the private network base station is in communication connection with a plurality of terminal devices, the local adapter is further configured to: acquiring preset data transmission sequences of two adjacent terminal devices; determining the actual data transmission sequence of two adjacent terminal devices; and when the actual data transmission sequence is different from the preset data transmission sequence, scheduling the time slot resources of the private network base station based on the actual data transmission sequence and the resource linked list.

The resource allocation operation in the remote controller may be implemented based on the predicted arrival time of the data packet, where when there may be a prediction error in the predicted arrival time of the data packet, the prediction error may cause a problem of resource underutilization in the private network base station, and on one hand, if the predicted arrival time is earlier, the allocated resource is still unused and wasted. On the other hand, if the predicted time is later, the data must wait until resources are available, which can result in longer network delays. To solve this problem, the local adapter adopts a heuristic algorithm to adjust the resource allocation, the algorithm can determine a resource linked list corresponding to the time slot resource scheduling information after obtaining the time slot resource scheduling information, the resource linked list comprises a plurality of ordered linked list nodes, each linked list node can correspond to the allocated MCS for the UE and the allocated number of available time slot resources (for example, PRB), and the local adapter can perform specific resource scheduling operation in combination with the above resource linked list according to the following manner: 1) If there is a real-time RAN event that requires resources, for example: frame retransmission, UE random access and periodic broadcast, the local adapter postpones the resource allocation operation; 2) The local adapter may determine the allocated PRBs for each UE, and when there are spare resources, may reclaim the spare resources and reduce the allocated PRBs, and if necessary, reallocate the reclaimed PRBs to other UEs; 3) If the previous data packet arrives later than the next data packet in the prediction, the local adapter exchanges two resource decisions; 4) The allocated resources that are not fully consumed in the current control period are reserved for the next control period. In addition, the local adapter can also allocate a survival time for the allocation decision corresponding to each linked list node, so as to avoid staying in the allocation policy linked list indefinitely. Through resource allocation adjustment, the base station can timely respond to the RAN event, tolerate prediction errors and effectively use radio resources.
