Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
It should be noted that the features of the embodiments and examples of the present invention may be combined with each other without conflict.
It should be noted that: "first," "second," and the like are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Currently, in the discussion about O-RAN, the interface to the management and data collection of nRT RIC is involved. One implementation is to manage the nRT RIC as a whole. As shown in FIG. 1, a wireless intelligent controller (RIC), an O-CU-CP and an O-CU-UP are managed as one Management Element (ME). The O1 interface is an interface for managing O-RAN by operation, maintenance and management (OAM), specifically, the O1 interface is connected to the nRT RIC, and the OAM interacts with the O-RAN in management through the O1 interface.
For nRT RIC, a distributed architecture may be adopted for deployment, as shown in fig. 2. In the distributed architecture, the function of nRT RIC may be divided into a plurality of modules (part 1, part2 in fig. 2), and data interaction is performed between the modules through a private Interface (private Interface).
Specifically, Part1 has a function of wireless resource coordination between base stations, and specifically may include user coordination between two base stations, dynamic, static or semi-static coordination of cell resources repeatedly covered between base stations, and the like, and data forwarding control during seamless handover;
part2, which has a base station-oriented internal radio resource management function, may specifically include a cell-level resource management function of each cell running on the base station, allocation and management of static, dynamic, and/or semi-static resources of each user in each cell, and the like, and also include storage and management of a context of the UE, and the like.
Since Part2 is oriented to the radio resource management function inside the base station, it can be deployed together with the base station according to the location of the base station, and of course, it can also be deployed separately from the base station.
In a distributed architecture, since the location of each nRT RIC is not fixed, and information synchronization between modules is also a great challenge, the interface of nRT RIC and O1 interfaces needs to be defined.
Based on this, in various embodiments of the present invention, a new functional module is introduced to complete the functions of sorting the nRT RIC data collection, forwarding the information, and the like.
In the first aspect, the newly introduced functional module organizes the nRT RIC data collection and sends the nRT RIC data collection to an external demand entity (which may be understood as a management device).
Based on this, an embodiment of the present invention provides an information Processing method, which is applied to an information Processing apparatus, that is, a newly introduced function Module, which may be referred to as a Unified Processing Module (UPM), as shown in fig. 3, and includes:
step 301: receiving measurement information sent by at least one nRT RIC;
here, a part of the at least one nRT RIC has a base station internal radio resource management function; another part of the at least one nRT RIC has a wireless resource coordination function between base stations; the nRT RIC having a function of managing radio resources inside the base station and the nRT RIC having a function of coordinating radio resources between the base stations can communicate with each other.
That is, according to the scheme provided by the embodiment of the present invention, nRT RIC adopts the distributed architecture shown in fig. 2.
Step 302: reporting the received measurement information;
step 303: and reporting the measurement information after the reporting processing to the management equipment.
In step 301, in actual application, measurement information may be applied to the nRT RIC by actively initiating a request, or measurement information of the nRT RIC may be collected by periodically reporting the nRT RIC, or a reporting application of the nRT RIC may be received, and it is determined that measurement information of the nRT RIC is collected by collecting a corresponding measurement information manner.
Based on this, in an embodiment, when receiving the measurement information, the method includes at least one of:
receiving measurement information periodically reported by corresponding nRT RIC;
sending a measurement query application to the corresponding nRT RIC; receiving measurement information reported by the corresponding nRT RIC based on the measurement query application;
receiving a measurement reporting application sent by a corresponding nRT RIC; sending an application acknowledgement to the corresponding nRT RIC; and receiving the measurement information reported by the corresponding nRT RIC based on the application confirmation.
Wherein the sending of the measurement query application to the corresponding nRT RIC comprises:
and sending a measurement query application to the corresponding nRT RIC based on a management command issued by the management device.
That is, the information processing apparatus analyzes the request information transmitted by the management device, converts the request information into an internal information collection instruction, and transmits a measurement query application to the nRT RIC based on the information collection instruction.
Here, in actual application, how to collect measurement information of nRT RIC may be selected as needed.
In practical application, after receiving the measurement information sent by the nRT RIC, the information processing apparatus may further store the measurement information locally, that is, locally store the measurement information reported by at least one nRT RIC, so as to obtain the measurement information in time when needed in the future.
In step 302, the reporting process mainly includes processing the data according to the external requirement entity.
Based on this, in an embodiment, the reporting the received measurement information includes:
receiving a message issued by the management equipment;
analyzing the received message to obtain a management instruction;
based on the processing instruction, at least one of the following operations is carried out on the received measurement information to obtain processed data:
classifying the received measurement information;
calculating the received measurement information;
merging the received measurement information;
smoothing the received measurement information;
accumulating the received measurement information;
and carrying out mean processing on the received measurement information.
The classification of the received measurement information may include, in addition to the content classification, association of parameters from different nRT RIC's and association of data for one user, for example, data for one user may come from different protocol layers such as L1, L2, or L3, and the classification may be performed based on the information of the user.
The calculation refers to performing some operations on the original measurement information to obtain the required parameters. For example, the number of bits transmitted per second (bps) is obtained from the measured time interval, or the average transmission amount (number of bits) within 1s is obtained.
The merging refers to merging the raw measurement information, such as taking a maximum value, a minimum value, or an average value among the multiple measurement values.
The smoothing process may be performed according to the need, for example, the smoothing process is performed by smoothly combining data of different time intervals, for example, by using the following formula:
Xn+1＝Xn+X/T (1)
wherein Xn +1 is the total value after the current smoothing, Xn represents the total value after the last smoothing, the initial value is 0 or a value determined by simulation, and X represents the value of the current time; t represents a coefficient, usually a constant, which is empirically derived.
In practical applications, the accumulation may be a linear accumulation of data.
The specific processing procedure of the averaging processing may be determined according to the need, such as normalized averaging processing.
In practical application, the information processing device can also locally store the processed data and the data in the processing process so as to be timely known in the following needs.
Based on this, in an embodiment, the method may further include at least one of:
locally saving the processed data;
intermediate data resulting from operating on the received measurement information is stored locally.
Here, the intermediate data refers to data generated during the above operation on the received measurement information, such as storing an intermediate result of the measurement information calculation. For example, the period of receiving the measurement information is 1ms, and if 10ms is needed, the value after the calculation of the currently received parameter can be stored locally.
The reporting process also comprises the conversion of information formats, and information is filled in according to formats specified by the external demand entities.
Based on this, in an embodiment, the reporting the received measurement information includes:
and performing message assembly on the received measurement information based on the interface message format of the management equipment.
In actual application, the information processing device can interact with the management equipment through an upper layer interface.
Specifically, the information processing apparatus may interact with the management device through an O1 interface or an a1 interface.
In practical application, the management device refers to a network management function entity, such as OAM.
In practical applications, the information processing apparatus may further perform self-optimization (expressed as self optimization) on part of locally stored data, so as to subsequently enable the management device to accelerate convergence of cell or user-related control parameters.
Based on this, in an embodiment, the method further comprises:
and updating the parameters of the user and/or the cell level in the locally stored measurement related information by combining a preset model based on the locally stored measurement related information.
Here, in actual application, the preset model may be determined as needed, for example, the preset model may be an Artificial Intelligence (AI) model for determining an air interface movement trajectory of a user, an AI model for determining a cell load law, a model for statistical characteristics of a user and a cell based on big data, and the like.
In practice, the information processing apparatus may update the parameters at the user and/or cell level in the locally stored measurement-related information either off-line or on-line.
Wherein, the updating of the user and/or cell level parameters in the locally stored measurement related information under the offline condition means: updating parameters of a user level and/or a cell level in the locally stored measurement related information when no function with higher priority than the self-optimization function needs to run in the environment in which the information processing device runs; when a function with higher priority than the self-optimization function needs to be run, updating of the user and/or cell level parameters in the locally stored measurement related information is stopped.
Accordingly, said updating of user and/or cell level parameters in locally stored measurement related information while online refers to: in the environment in which the information processing apparatus operates, user and/or cell level parameters in the locally stored measurement related information are updated whenever trigger information is received, such as new parameters or an external trigger.
In a second aspect, the newly introduced functional module forwards the information sent by the management device to the corresponding nRT RIC.
Based on this, an embodiment of the present invention provides an information processing apparatus, which is applied to an information processing apparatus, that is, a newly introduced function module, which may be referred to as a UPM, as shown in fig. 4, where the method includes:
step 401: receiving a message sent by a management device;
step 402: the information in the message is distributed to at least one nRT RIC.
Wherein part of the at least one nRT RIC has a base station internal radio resource management function; another part of the at least one nRT RIC has a wireless resource coordination function between base stations; the nRT RIC having a function of managing radio resources inside the base station and the nRT RIC having a function of coordinating radio resources between the base stations can communicate with each other.
That is to say, according to the solution provided by the embodiment of the present invention, the nRT RIC adopts the distributed architecture shown in fig. 2.
In step 401, after receiving the message sent by the management device, the information processing apparatus parses the message to obtain the information in the message, and then distributes the message to at least one nRT RIC as required.
In actual application, the information processing device may interact with the management apparatus through an upper interface.
Specifically, the information processing apparatus may interact with the management device through an O1 interface or an a1 interface.
In practical application, the management device refers to a network management function entity, such as OAM.
The information processing method provided by the embodiment of the invention receives the measurement information sent by at least one nRT RIC; reporting the received measurement information; reporting the measurement information after the reporting processing to a management device; and/or receiving a message sent by the management equipment; distributing information in the message to at least one nRT RIC; wherein part of the at least one nRT RIC has a base station internal radio resource management function; another part of the at least one nRT RIC has a wireless resource coordination function between base stations; the nRT RIC with the function of managing the wireless resources inside the base station and the nRT RIC with the function of coordinating the wireless resources among the base stations can communicate, and the functions of collecting the data of the nRT RICs, collecting the information, forwarding the information and the like are completed through a new functional module, so that the information synchronization and management under the distributed nRT RIC framework are realized.
The present invention will be described in further detail with reference to the following application examples.
In the embodiment of the application, a UPM is newly added in an nrT RIC framework, and the UPM at least comprises the following two functions:
first, information is collected from each nRT RIC;
specifically, the information can be applied to each nRT RIC in an active request initiating manner, the information can be collected from each nRT RIC in a periodic manner, or whether the information is collected is determined after the report application of each nRT RIC is received.
Secondly, the processing function of the information;
the processing functions may include:
converting the information format; specifically, after the measurement information is collected from each nRT RIC, the information is filled in according to a format specified by an external demand entity and then sent to the external entity (i.e., management device) with demand;
sorting and filtering information content; specifically, according to the requirements of the external entity, the data are subjected to smoothing, averaging, fitting, accumulating, combining and other operations and then are sent to the external entity with the requirements according to the requirements;
and receiving request information sent by an external entity, analyzing the request information and converting the request information into an internal information collection instruction.
The UPM may further include an interface function for interacting with an external entity, and specifically may include functions of flow management, fault tolerance management, conversion of message format, and the like for the interactive interface.
That is, the UPM provides a unified internal interface and external interface for the nRT RIC, and the unified interface opens up the capability of Radio Resource Management (RRM), that is, the requirements of radio resource management can be sent to the nRT RIC through the UPM by OAM or other external function module.
Externally, the UPM interfaces with network management function entities (such as OAM) through a1 or O1 interfaces, as shown in fig. 5. The A1 and the O1 belong to interfaces with different types or different message contents, and the UPM can be simultaneously adapted to one or more interfaces connected to the outside during actual application.
Inside the nRT RIC architecture, the UPM is connected to each nRT RIC (dashed connection in the figure), and the collection of measurement information is performed by interaction with each nRT RIC. Specifically, the UPM is connected with the Part1 and the Part2, and in practical application, when the nRT RIC generates one Instance (Instance) of the Part2 for one base station, the Instance of the Part2 is connected with the UPM.
The function of the UPM is described in detail below.
As shown in fig. 6, the functions of the UPM mainly include: a storage function (Memory), an upper layer interface (such as an a1 or O1 interface) parsing function, a message adaptation function, a data collection function, and an information processing function; wherein the content of the first and second substances,
a storage function: the UPM provides all information storage functions for UPM operation, including various information storage functions such as collected information, calculated intermediate information, interface analysis information and the like, and provides a uniform interface.
The upper layer interface analysis function: aiming at different interface types, corresponding adaptation functions are provided, which comprise: analyzing the received messages on different upper layer interfaces, and distributing the analyzed data to each internal nRT RIC; and receiving the content which is constructed and sent to the upper layer interface according to different interface formats.
The message adaptation function: and generating a message to be reported according to the data content provided by the information processing function module. Generating different sending contents according to the requirements of different upper layer interfaces, wherein the main functions comprise: classification of data content, filling of message content, sending of message body, and acknowledgement after message body sending, etc. According to the external requirement of the nRT RIC, such as Non-RT RIC, OAM, an indication message aiming at RRM is generated, and the open function of RRM to the outside is realized. For example, OAM sends a demand for Load Balancing (LB) to nRT RIC through an O1 interface, and the UPM sends the demand for LB to nRT RIC, so that nRT RIC determines whether RRM needs to be triggered to generate a switching behavior, whether admission control needs to be generated, whether a user releasing behavior is generated, and the like, according to the specific content of the demand for LB; and generating an indication to the RRM according to the decision result.
A data collection function: the UPM interacts with the nRT RICs and is responsible for triggering the nRT RICs to send measurement information and providing a uniform data collection interface and flow for the nRT RICs. And receiving the measurement information sent by each nRT RIC. And sends the information to the storage function module for storage. After receiving the measurement information, the received measurement information needs to be classified in real time, and a correctness checking function is performed, such as removing obviously wrong parameter values, combining repeated parameter values, and associating parameters from different nRT RIC. For data of one user, the data may come from different protocol layers such as L1, L2 or L3, and when collecting data, association processing is performed according to the information of the user, and the data after association processing is written into the storage module.
Here, for the measurement information of each nRT RIC, detailed description is given below in parts 1 and Part 2.
Measurement information of Part 1: part1 is primarily responsible for control functions between multiple Central Units (CUs), so the measurement information characteristic of Part1 is: the quantity is large, and the requirement on processing instantaneity is low. Therefore, the information of the UPM and the Part1 mainly includes query class information and periodic reporting class information.
The query type information mainly comprises: the UPM sends the information of the query application to Part1 according to the requirement sent by the upper layer interface, including the number of users in each cell, the number of users moved after equalization, the average rate and the maximum rate of the air interface in each cell, the number of times that the rate of the air interface in each cell is lower than a minimum threshold, the time length of each time and the like.
For the periodic reporting type information, Part1 reports the information between cells according to the time or data volume period specified by the UPM, such as the number of times of inter-cell interference coordination (ICIC) start, and the changes of the maximum air interface rate, average rate, etc. of the neighboring cells after ICIC start.
The measurement information of Part2 includes: query type information, periodic reporting type information and event triggering type information.
Wherein the content of the first and second substances,
for the query type information, the UPM sends the information of the query application to Part2 according to the requirement sent by the upper layer interface, including the parameters of the user level, including the number of times of user link interruption, the number of times of 0 rate on the link, the number of times of data loss on the link, the bit or byte length, etc.
For the periodic reporting type information, Part2 reports the user-level information according to the time or data volume period specified by the UPM, including the length of the data bit or byte discarded by the UE in the period, the length of the retransmitted data bit or byte, the average rate of the UE air interface, the rate of successful data transmission at one time of the air interface, the rate of successful data retransmission and transmission at the air interface, the rate of failed data transmission at the air interface, and the like.
The event trigger type information is: the UPM generates information corresponding to the command to Part2 upon receiving an external radio resource management request. When the Part2 needs UPM to make a decision, an application is sent to the UPM, and when the UPM makes a decision that the report is needed, the Part2 reports corresponding information.
An information processing function: based on the data information collected by the data collection function module, the collected data is classified, calculated, merged, smoothed, accumulated, averaged and the like. And processing the data according to the requirements of the messages reported by various interfaces. Meanwhile, Self-Optimization (Self Optimization) is performed based on the information stored by the storage function module.
Specifically, the self-optimization function optimizes information of the user and/or the cell by introducing a self-optimization tool, such as an AI model for determining an air interface movement track of the user, an AI model for determining a cell load rule, a statistical characteristic tool of the user and the cell based on big data, and the like, based on the information stored in the storage function module, and writes updated information into the storage function module. The self-optimization function provides new information processing capability for nRT RIC, and by introducing various tool software, these parameters can be iteratively upgraded, i.e. updated, in an offline or online manner, thereby helping to accelerate convergence of cell and/or user related control parameters.
The offline operation of the UPM self-optimization function (i.e. the iterative upgrade is performed on the parameters in an offline manner) refers to: in the environment where the nRT RIC is operated, when the operation environment does not have a function of higher priority than the self-optimization function to be operated, the self-optimization function is started, thereby performing optimization for the parameter; when a function with higher priority than the self-optimization function needs to run, the self-optimization function is stopped.
The online operation of the UPM self-optimization function (i.e. the iterative upgrade for these parameters in an online manner) means that: in the environment where nRT RIC operates, when a new parameter or a channel external trigger is received, the self-optimization function is started, so as to perform optimization for new information, and always keep the data stored in the storage function module to be optimized data.
The self-optimization function embodies that the nRT RIC has an intelligent algorithm and has intelligent message storage and processing functions, and the self-management and self-optimization intelligentization of the nRT RIC is really realized.
