It should be further understood that the expression “comprising” or “include” used in the specification of the disclosure means the existence of the features, integers, steps, operations, elements and/or components, but does not preclude the existence or addition of one or more other features, integers, steps, operations, elements, components and/or combinations thereof.

The phrase “and/or” used herein includes all or any one and all combinations of one or more of the associated listed items.

In order to better understand and explain the solutions of the embodiments of the disclosure, some technologies involved in the embodiments of the disclosure are briefly described below.

Coverage classification may include or be referred to as coverage level, coverage class, and so on.

The coverage characteristics may include RSRP, signal to interference plus noise ratio (SINR), reference signal receiving quality (RSRQ), or other indicators that indicate the coverage classification. According to the current 3GPP protocol, based on the division of coverage levels, NB-IoT supports up to 3 coverage levels and enhanced machine type communication (eMTC) supports up to 4 coverage levels. The maximum number of coverage levels may change in other wireless communication systems or future 3GPP protocol.

According to the current 3GPP protocol, different coverage levels are determined by defining reference signal receiving power (RSRP) thresholds. In the future 3GPP protocol or in other wireless communication systems, the division of coverage classifications may be determined by defining other threshold indicators, including SINR, RSRQ, or other indicators that identify coverage differences. In this case, RSRP is taken as an example.

The resource configuration (a set of parameters affected by RSRP threshold) for each coverage level may include random access resource configuration, which includes time domain/frequency domain resources for transmitting the preamble (msg1) and the number of repetitions of the preamble.

Where, time domain resources include time domain periods, frequency domain resources include the number of subcarriers, the number of repetitions of preamble represents the number of repetitions for transmission required for transmitting a preamble, scheduling resource configuration includes the number of repetitions for transmission and/or modulation and coding scheme (MCS) configuration for physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH).

Specifically, the IoT terminal may compare the measured signal strength (RSRP) with the RSRP threshold to determine the coverage level (CL) where it is located, and then use the corresponding (random access channel (RACH) resource to initiate random access, a base station selects the corresponding resource configuration based on the CL that the UE accesses. For example, for a CL with a good signal strength, the transmission requirement can be met without setting the number of repetitions or with a small amount of repetitions while ensuring a higher data transmission rate, for a CL with a poor signal strength, the coverage characteristics can be met by setting a larger number of repetitions.

The open radio access network (O-RAN) focuses on the needs of network intelligence, interface openness, open source software and hardware white box, which is intended to promote the openness of wireless device interfaces, and realize intelligent wireless networks by introducing new technologies such as artificial intelligence, thereby to raise the openness of the next generation wireless communication network to a new level.

FIG. 5 is a schematic diagram of an O-RAN logical architecture according to an embodiment of the disclosure.

Referring to FIG. 5, according to an open radio access network (O-RAN) specification, a logical architecture of an open radio access network (O-RAN)is shown. The entities of wireless side may include a Near-RT RIC, an O-RAN control unit control plane (O-CU-CP), an O-RAN control unit user plane (O-CU-UP), an O-RAN data unit (O-DU), and an O-RAN evolved node B (O-eNB).

Service management and orchestration (SMO) entities may provide a variety of management services and network management functions, such as RAN management, core network management, transmission management, and end-to-end slice management.

Non-real time RAN intelligent controller (Non-RT RIC) is a logical entity built into SMO, which supports non-real-time control and optimization of RAN network elements and resources, artificial intelligence (AI)/machine learning (ML) model establishing, reasoning and updating, RAN is optimized through data analysis and AI/ML training/reasoning, and it provides strategic guidance and ML model management to the near-real Time RAN intelligent controller (Near-RT RIC) through the AI interface.

The Near-RT RIC logical entity may support near-real-time control and optimization of RAN network elements and resources, and may include artificial intelligence (AI)/machine learning (ML) model training, reasoning and updating, and strategy guidance. The Near-RT RIC provides network optimization instructions to the E2 node through the E2 interface.

E2 node: which may include O-RAN control unit control plane (O-CU-CP), O-RAN control unit user plane (O-CU-UP), O-RAN data unit (O-DU), O-eNB and other entities, where O-CU-CP, O-CU-UP, and O-DU are used for 5G new radio (NR) access, O-eNB is used for evolved universal mobile telecommunications system (UMTS) terrestrial radio access (E-UTRA) access. Compared with the CU-CP, CU-UP and DU of the non-O-RAN system, the E2 node adds support for the E2 interface.

O-eNB: which is eNB or ng-eNB supporting O-RAN architecture.

O-Cloud: which is O-RAN cloud computing platform.

External server: which is a server for various application APP, etc., and may provide SMO with rich data.

The O-RAN architecture mainly includes four interfaces:

A1: which is located between Non-RT RIC and near-RT RIC, and supports strategy management, rich information and ML model management services.

E2: which is used to connect the near-RT RIC and E2 node. One E2 node can only be connected to one near-RT RIC. The Near-RT RIC entity can collect the near-real-time information (UE-level or cell-level) measured by respective functional entity of the wireless network through the E2 interface, and can also issue control command words to the base station through the E2 interface, and finally the E2 interface may control the behavior of the base station.

O1: which is an interface located between the O-RAN managed entity (near-RT RIC, E2 node) and the O-RAN management entity (SMO), and supports operation and management, including network fault/configuration/accounting/performance/security (F CAPS) management, physical network function (PNF) software management and file management.

O2: which connects SMO and O-Cloud to support O-RAN virtualization.

Open fronthaul M-plane interface: which is located between SMO and O-RAN radio unit (O-RU) to support O-RU management.

In order to make the objectives, technical solutions, and advantages of the disclosure clear, the implementations of the disclosure will be further described in detail below in conjunction with the accompanying drawings.

To support large-scale connections, 3GPP has proposed two cellular IoT protocol standards of Narrow Band IoT (NB-IoT) and enhanced machine type communication (eMTC). In the protocol, 3GPP introduced the concept of coverage level (CL).

FIG. 1 is a schematic diagram of 3GPP NB-IoT coverage level (CL) according to the related art.

Referring to FIG. 1, CL is divided by defining a signal strength threshold (rsrpThreshold), and differentiated resource configurations are defined for respective coverage levels to achieve requirements of coverage, capacity, and management for a large number of terminals.

CL division is mainly achieved by defining reference signal receiving power (RSRP) threshold. In actual networks, the RSRP threshold is generally determined based on the maximum and deepest coverage of the cell. However, since IoT services are mostly transmitted infrequently, in fact, the distribution of IoT terminals that truly have service transmitting and receiving requirements in the cell has time-varying characteristics.

FIG. 2 is a schematic diagram of a distribution of IoT terminals during a day according to the related art.

FIG. 3 is a schematic diagram of a distribution of IoT terminals during a night according to the related art.

Referring to FIGS. 2 and 3, for example, IoT terminals are distributed evenly during the day, but at night, most of the terminals that transmit IoT services fall into a range of strong signal strength. In this case, a fixed division of three CLs and a fixed resource configuration may lead to insufficient resources for CL0, which may cause access congestion; at the same time, the resources reserved for CL1 and CL2 may be wasted since the actual number of users is small, thereby reducing resource utilization.

The semi-static resource configuration cannot adapt to the time-varying distribution of IoT terminals, which results in an increased power consumption and a decreased system capacity.

As mentioned above, the distribution of IoT terminals that truly have service transmitting and receiving requirements in the cell has time-varying characteristics. The CL-based semi-static resource configuration cannot adapt to the time-varying characteristics of terminal distribution, and may allocate a larger number of repetitions, which not only wastes terminal power, but also causes unnecessary resource waste, thereby reducing system capacity.

FIG. 4 is a schematic diagram of distribution characteristics of IoT terminals according to the related art.

Referring to FIG. 4, during the morning time period, an actual effective terminal of CL0 in the area is UE1/UE2, during the noon time period, the actual effective terminal of CL0 is UE1/UE5, and during the afternoon time period, the actual effective terminal of CL0 is UE1/UE2. Where, UE1/UE5 have higher RSRP, it may meet transmission requirement that the number of repetitions is 1, UE2 has lower RSRP, and the number of repetitions is 2. In this case, if it uses the semi-static configuration that the number of repetitions is 2, the number of repetitions for UE1 and UE5 would be too high during the noon time period, which results in an increased resource occupation.

An information processing method is provided according to an embodiment of the present disclosure, which is used in a first network device.

Alternative Embodiment 2

FIGS. 16A and 16B show a principle flow of information processing under an O-RAN system and modules and interfaces in the corresponding O-RAN system framework according to various embodiments of the disclosure.

Referring to FIGS. 16A and 16B, in operation S1-16, an SMO module collects the location information of a terminal and the feature information of an IoT service (such as the periodic characteristic of the service) from an application server. The above information is used to realize the estimation and prediction of IoT coverage characteristics and service feature in the cell.

The location of IoT users is mostly static (for example, meter reading service) or the running trajectory is regular (for example, high-voltage power line inspection service). Operators may obtain relevant information from vertical industries and store it in the operation server in advance.

IoT services generally have periodic regularities. For example, the humidity detection service detects and reports the humidity indicators of the surrounding environment every fixed time interval. Operators can also store the relevant requirement information of vertical industries in the operation server in advance.

SMO may obtain the configuration information about the terminals and services of vertical industries (such as location and periodicity of service occurrence) stored in the server in advance from the running server through the public interface.

In operation S2-16, the SMO receives information from the O-eNB or O-DU through the O1 interface. The information may include the measurements about RSRP and BSR reported by the IoT terminal, and information about the base station measurement statistics and configuration, the base station measurement statistics and configuration information may include the number of Msg1s received in each CL, the number of Msg4s received in each CL, and the UE downlink BO size, the current cell configuration information may include RACH configuration information (number of subcarrier resources for each CL, the number of repetitions of the preamble code, period), the MCS value of the uplink transmission of each CL, the number of repetitions of the uplink transmission of each CL, the number of repetitions for transmission of the Ack/NACK for Msg4 of each CL, the number of repetitions for transmission of Ack/NACK for the PDSCH of each CL, the MCS value of the downlink transmission of each CL, the number of repetitions of the downlink transmission of each CL, the number of repetitions of the CSS transmission of each CL, the number of repetitions of the USS transmission of each CL, and the RSRP threshold corresponding to the CL in the cell.

In operation S3-16, the SMO transmits the received measurements to Non-RT RIC via the internal bus. The Non-RT RIC analyzes the measurement and statistical results, which involves using user BO and vertical industry preset period or time settings to obtain the periodic characteristics of IoT services under the coverage of respective RSRPs, involves using the number of Msg1 and Msg4 received in each CL and the corresponding RACH configuration information to analyze the capacity performance reference under different RACH configurations. This capacity reference gives different RACH configurations (the number of repetitions, period, the number of subcarriers), the access success rate or the access capacity value of the system under any number of users with access requirements.

In operation S4-16, the Non-RT RIC uses AI/ML to predict the service distribution in the next time period, which involves Non-RT RIC using historical data (such as the data of the past year) to train the AI model to obtain an AI model suitable for IoT service in a cell. It involves using the trained AI model in combining with the service period distribution characteristics obtained in operation S3-16 and the actual measurement data in the last N (>=1) periods to predict the distribution of the IoT service capacity over time under different RSRPs in the next period.

In operation S5-16, the Non-RT RIC dynamically configures cell radio resources and transmission parameters based on the distribution characteristics of IoT services in the cell, which includes clustering IoT terminals in the same cell by using the capacity weighted variance analysis method, which is realized particularly through estimating and setting different RSRP thresholds. Further, for IoT users in the same cluster, the fluctuation features of the coverage characteristics over time are estimated, and the number of repetitions required for data transmission and the change of MCS are dynamically estimated based on the fluctuation features, so as to obtain the number of repetitions of data transmission and the optimal configuration of MCS for the same type of IoT users in different time periods. On the other hand, in order to ensure the access performance of the same type of IoT users, it may estimate the capacity requirement distribution of the same type of user IoT services in different time periods, and use the capacity performance reference under different RACH configurations obtained in operation S3-16 to estimate the best RACH resource and transmission parameter configuration in different time periods (including the number of RACH subcarriers, period, and the number of repetitions).

In operation S6-16, it may transmit the resource and transmission parameter configuration obtained in operation S5-16 to SMO through the internal bus interface Non-RT RIC. Next, SMO transmits the relevant parameter configuration to the O-eNB or O-DU by using the O1 interface. Finally, the O-eNB or O-DU completes the update of resource configuration parameters.
