Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a network energy-saving wake-up method, apparatus, communication device, and storage medium. Background Art

[0002] When a base station enters a low-traffic state, the coverage of cell-edge users and the performance perception will be weakened. When the base station enters shallow sleep or deep sleep, signal reception and transmission will no longer be performed. Therefore, in geographical areas where the coverage is weakened or disappeared, the base station in the energy-saving state cannot perceive the traffic and wake up, and a cooperation-based method needs to be designed for base station wake-up.

[0003] Among the existing base station wake-up methods, one wake-up method is that a user equipment (UE) wakes up a base station entering the quasi-sleep mode, but this requires the cell to still retain the uplink signal detection system during shallow sleep or deep sleep, which affects the energy-saving effect; another wake-up method is to wake up the base station by evaluating the overall energy efficiency of the network, but the users under the cell in the sleep state cannot be perceived; the method based on user trajectories and traffic prediction to judge the cell where the user will arrive in the future requires a large amount of prediction calculations, and the accuracy needs to be verified.

[0116] The technical solution of the embodiment of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0117] The technical solution of the embodiment of the present invention can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Long Term Evolution (LTE) system or 5G system, etc. Optionally, the 5G system or 5G network can also be referred to as a New Radio (NR) system or NR network.

[0118] Exemplarily, the communication system to which the embodiment of the present invention is applied may include a network device and a terminal device (which can also be referred to as a terminal, a communication terminal, etc.); the network device can be a device that communicates with the terminal device. Among them, the network device can provide communication coverage within a certain area range and can communicate with terminals located in this area. Optionally, the network device can be a base station in each communication system, such as an Evolutional Node B (eNB) in the LTE system, or a base station (gNB) in the 5G system or NR system.

[0119] It should be understood that in the embodiment of the present application, a device with communication functions in a network / system can be referred to as a communication device. The communication device can include a network device and a terminal with communication functions. The network device and the terminal device can be the specific devices described above, which will not be elaborated here; the communication device can also include other devices in the communication system, such as other network entities such as a network controller and a mobility management entity. This is not limited in the embodiment of the present invention.

[0120] It should be understood that the terms "system" and "network" in this article are often used interchangeably herein. The term " / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this article generally represents an "or" relationship between the preceding and following associated objects.

[0121] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0122] Before elaborating on the technical solutions of the embodiments of the present invention, a brief description of traditional base station energy saving and wake-up technologies is first provided.

[0123] Currently, the base station energy saving and wake-up technology mainly is that the base station determines the level of base station energy saving and whether to wake up according to the dynamic traffic of the cell. One situation is that the base station energy saving levels are low-traffic energy saving, shallow sleep, and deep sleep, as shown in Table 1. The base station pre-sets the traffic thresholds for each energy saving level, and makes a decision on base station energy saving or determines whether to wake up the base station by comparing the monitored or predicted real-time traffic of the cell with the set thresholds.

[0124] Table 1

[0125]

[0126] However, when the base station enters the low-traffic energy saving state, the coverage and performance perception of cell-edge users will be weakened; when the base station enters the shallow sleep or deep sleep state, the network will no longer receive and send signals. Therefore, in the geographical areas where the coverage is weakened or disappeared, the cells in the energy saving state cannot sense the traffic and wake up, and a cooperation-based method needs to be designed to wake up the base station.

[0127] Based on this, the embodiments of the present invention provide a network energy saving and wake-up method. Figure 1 For the flow diagram of the network energy saving and wake-up method of the embodiments of the present invention Figure 1 ; as Figure 1 shown, the method includes:

[0128] Step 101: A first network device obtains first information sent by at least one first base station; the first information includes at least first data related to a user and first location information of the user;

[0129] Step 102: The first network device sends second information to the second base station according to the first information, where the second information is used for network energy saving wake-up.

[0130] In this embodiment, the first network device assists in performing network energy-saving wake-up, for example, by sending a second message to the second base station to perform network energy-saving wake-up. In some optional embodiments, the first network device may be a base station in a group of base stations or a base station cluster, and the base station may serve as a control base station in the group of base stations or the base station cluster to assist in performing network energy-saving wake-up. In other optional embodiments, the first network device may be a control device, a server, a network function, etc. that is different from the base station, and the control device, server, and network function may be a control platform, an intelligent control platform, an intelligent control platform, an intelligent controller, etc.; exemplarily, the first network device may be a near-real-time RAN intelligent controller (Near-RT RIC) in an open radio access network (O-RAN, Open-Radio Access Network), which may realize near-real-time control and optimization of RAN elements and resources through fine-grained data collection and operations performed through the E2 interface.

[0131] In this embodiment, the first base station and the second base station have an association relationship. In some optional embodiments, the association relationship may at least include: the coverage area of the first base station and the coverage area of the second base station have overlapping coverage areas, or the cell where the first base station is located and the cell where the second base station is located can be neighboring cells of each other, or the first base station and the second base station can be neighboring base stations of each other.

[0132] In this embodiment, before executing step 102, the second base station is in an energy-saving state, which can be, for example, a low-service energy-saving state, a shallow sleep state, or a deep sleep state as recorded in Table 1, or the coverage area of the second base station is an area where coverage is weakened or coverage disappears. Exemplarily, when the second base station is in a low-service energy-saving state, since some transmitting radio frequency channels are closed (or dormant), the first information can be sent to the first network device through the partially opened transmitting radio frequency channels. When the second base station is in a shallow sleep state or a deep sleep state, since analog devices such as power amplifiers and transceivers are turned off, the first information cannot be sent to the first network device.

[0133] In some optional embodiments, the at least one first base station includes the at least one second base station or a neighboring cell of the second base station.

[0134] In an embodiment of the present invention, the first network device formulates a wake-up policy based on the first user-related data sent by the first base station and the first location information of the user, and sends second information for network energy-saving wake-up to the second base station. That is, network energy-saving wake-up is performed in a collaborative manner, comprehensively considering the user experience, and ensuring the user experience without affecting the energy-saving effect of the base station.

[0135] In various embodiments of the present invention, the network energy-saving wake-up can also be referred to as Energy saving network, Energy Saving or energy-saving wake-up.

[0136] In some optional embodiments, the first user-related data includes at least one of the following: user plane measurement information of the network device of the user / user group; performance metrics related to the mobility of the user / user group; performance metrics related to random access of the user / user group.

[0137] Exemplarily, the user plane measurement information of the network device of the user / user group may include one or more of the following: average uplink or downlink throughput (Average UL / DL Throughput), uplink or downlink scheduled IP throughput (UL / DLScheduled IP throughput), uplink or downlink physical resource block (PRB, Physical Resource Block) utilization (or usage), uplink or downlink buffer status (Buffer Status), uplink or downlink block error rate (BLER), uplink or downlink modulation and coding scheme (MCS, Modulation and Coding Scheme), etc.

[0138] The performance metrics related to the mobility of the user / user group may include, but are not limited to, information related to handover failure. Such information related to handover failure may be, for example: the number of handover failures related to mobility robustness optimization (MRO, MobilityRobustness Optimization). Exemplarily, the information related to handover failure may include, but is not limited to, the handover failure rate.

[0139] The performance metrics related to user / user group random access may include one or more of the following: information related to random access channel failure (RACH Failure); information related to radio link failure (RLF, Radio Link Failure); information related to UE context release (UE CONTEXT Release). Exemplarily, the information related to random access channel failure (RACH Failure) may include, but is not limited to, one or more of the following: the number of RACH failures, the RACH failure rate, the RACH cause, the number of RACH retries, etc. The information related to RLF may include, but is not limited to, one or more of the following: the number of RLF occurrences, the failure rate.

[0140] In some optional embodiments, the first location information includes, but is not limited to: Location and Velocity measurements. Exemplarily, the first location information may include, but is not limited to, one or more of the following: angle of arrival (AOA) information, longitude and latitude information, time of arrival (TOA) information, altitude information, speed, etc.

[0141] In some optional embodiments, base stations may be divided into at least two types based on different functions: basic coverage type (or main function) and supplementary hot spot type (or main function); different types (or main functions) of base stations may correspond to different first data, that is, different types (or main functions) of base stations send different metric data or key performance indicators (KPIs, Key Performance Indicator).

[0142] In some optional embodiments, the first data sent by the base station of the basic coverage type (or main function) may include at least one of the following: performance metrics related to the mobility of the user / user group, performance metrics related to user / user group random access; the first data sent by the base station of the supplementary hot spot type (or main function) may include the user plane measurement information of the network device of the user / user group.

[0143] In some optional embodiments, the second information includes at least one of the following: indication information for carrier activation or wake-up, indication information for channel activation or wake-up, indication information for cell activation or wake-up.

[0144] In this embodiment, the second information is used for energy-saving wake-up, that is, to indicate or cause the second base station to switch from the first state to the second state. The first state may be an energy-saving state, and the second state may be a non-energy-saving state, or alternatively, the energy-saving effect of the first state is better than that of the second state.

[0145] In some optional embodiments, the first state includes at least one of the following: carrier-off state, channel-off state, cell sleep state. The second state includes at least one of the following: carrier-on state, channel-on state, cell active state, etc.

[0146] In this embodiment, the first data is data related to users within the coverage area of the first base station. In some optional embodiments, the first data may be metric data or KPIs predefined or configured by the first network device. When the metric data or KPI value of a neighboring cell user (i.e., a user in the area where the first base station is located) is worse than a threshold, it can be considered that the experience of the neighboring cell user is poor, and the second base station needs to be woken up to provide better service. It should be noted that being worse than the threshold may mean that some metric data or KPI values are greater than or equal to the corresponding threshold, or some metric data or KPI values are less than or equal to the corresponding threshold. As long as it can lead to a poor user experience result, it can be considered that the current some metric data or KPI values are worse than the threshold.

[0147] In some optional embodiments, metric data or KPIs related to the type or main function of the base station can be predefined or configured based on the type or main function of the base station. For example, based on the base coverage type (or main function) of the base station, the base coverage type can predefined or configure metric data or KPIs related to coverage metrics; in the case where the base station is of the supplementary hotspot type (or main function), the supplementary hotspot type can predefined or configure metric data or KPIs related to performance metrics.

[0148] In other optional embodiments, the first network device can also define or configure metric data or KPIs related to performance metrics and coverage metrics, and jointly use them as metrics for energy-saving wake-up.

[0149] In practical applications, the first network device can judge the type or main function of the base station according to the base station deployment information; and then define or configure corresponding metric data or KPIs according to the type or main function of the base station, such as a base station of the base coverage type or a base station of the supplementary hotspot type.

[0150] In some optional embodiments, the first data sent by a base station of the base coverage type (or main function) may include at least one of the following: performance metrics related to the mobility of a user / user group, performance metrics related to the random access of a user / user group; the first data sent by a base station of the supplementary hotspot type (or main function) may include the user plane measurement information of the network device of the user / user group.

[0151] In some optional embodiments of the present invention, before the first network device obtains the first information sent by at least one first base station, the method further includes: the first network device sending a first subscription request to at least one third base station, where the first subscription request includes first subscription content and a first triggering method; the first subscription content includes second data related to a user and the second location information of the user; the first triggering method includes periodically reporting the first subscription content; or reporting the first subscription content when a first preset triggering condition is met; where the at least one third base station includes the at least one first base station, and / or the at least one third base station includes the at least one second base station.

[0152] In some optional embodiments, the first network device obtaining the first information sent by at least one first base station includes: the first network device receiving the first information sent by the at least one first base station according to the first triggering method.

[0153] In this embodiment, the first network device requests a subscription from at least one third base station within its coverage area for subscribing to second data related to a user and the second location information of the user. Where the at least one third base station includes the at least one first base station and / or the second base station, that is, the at least one first base station and / or the second base station can, based on the subscription of the first network device, report the first information to the first network device according to the first triggering method.

[0154] In this embodiment, the first network device can send different data related to the user in the first subscription request for different base station types or the main functions of the base stations. For example, for base stations of the basic coverage type or function, data related to the user of this type or function can be sent; for base stations of the supplementary hotspot type or function, data related to the user of this type or function can be sent. Alternatively, the first network device can also send the same data related to the user in the first subscription request for all third base stations within its coverage area, that is, send the same subscription content; after receiving the first subscription request, each third base station collects and reports the same metric data or KPIs, or after receiving the first subscription request, each third base station selects the metric data or KPIs to be reported according to its own type or function. This embodiment does not limit this.

[0155] In some optional embodiments, the data types included in the second data include the data types included in the first data. Exemplarily, the second data may include N data (or data types), and the first data may include M data (or data types), then M is less than or equal to N. It can be understood that the third base station can determine by itself the first data to be reported to the first network device according to the content in the first subscription request.

[0156] In this embodiment, the first triggering method includes periodically reporting the first subscribed content. That is, each third base station reports the first subscribed content (i.e., the first information) collected or measured to the first network device according to a set period. Alternatively, the first triggering method is to report the first subscribed content when a first preset triggering condition is met. Among them, the first preset triggering condition may be that the second data related to the user (or the second data subscribed by the base station) is worse than the first threshold corresponding to the second data, or the relative relationship between the second data related to two or more users.

[0157] Among them, the second data related to the user being worse than the first threshold corresponding to the second data specifically refers to the situation where the relevant parameters that can bring user experience are lower than the relevant threshold. That is, it can be considered that the experience of neighboring area users is poor, and the second base station needs to be woken up to provide better services. In practical applications, it can be that some indicator data or KPI values are greater than or equal to the corresponding first threshold, or some indicator data or KPI values are less than or equal to the corresponding first threshold. As long as it can bring a result of poor user experience, it can be considered that the user-related data is worse than the first threshold corresponding to the second data. For example, UL MCS>0, RLF rate>0, etc. Another example is that the first preset triggering condition may be the relative relationship between the second data related to two or more users, such as when Uplink Buffer Status>1000Byte, UL THP<1000kbps, etc.

[0158] In some optional embodiments, the second data related to the user includes one or more of the following: the user plane measurement information of the network device of the user / user group; the performance indicators related to the mobility of the user / user group; the performance indicators related to the random access of the user / user group.

[0159] Exemplarily, the user plane measurement information of the network device of the user / user group may include one or more of the following: average uplink or downlink throughput, uplink or downlink PRB utilization rate, uplink or downlink scheduled IP throughput (UL / DLScheduled IP throughput), uplink or downlink buffer status (Buffer Status), uplink or downlink block error rate (BLER), uplink or downlink MCS, etc.

[0160] The performance metrics related to the mobility of the user / user group may include, but are not limited to, information related to handover failure, such as the number of handover failures related to MRO (Number of handover failures related with MRO). Exemplarily, the information related to handover failure may include, but is not limited to, the handover failure rate.

[0161] The performance metrics related to the random access of the user / user group may include one or more of the following: information related to random access channel failure (RACH Failure); information related to radio link failure (Radio Link Failure); information related to UE context release (UE CONTEXT Release). Exemplarily, the information related to random access channel failure (RACH Failure) may include, but is not limited to, one or more of the following: the number of RACH failures, the RACH failure rate, the RACH cause, the number of RACH retries, etc. The information related to RLF may include, but is not limited to, one or more of the following: the number of RLF occurrences, the failure rate.

[0162] In some alternative embodiments, the second location information includes, but is not limited to, Location and Velocity measurements. Exemplarily, the second location information may include, but is not limited to, one or more of the following: AOA information, longitude and latitude information, TOA information, altitude information, velocity, etc.

[0163] In some alternative embodiments, base stations may be classified into at least two types based on different functions: basic coverage type (or main function) and supplementary hot spot type (or main function); different types (or main functions) of base stations may correspond to different first data, that is, different types (or main functions) of base stations send different metric data or key performance indicators (KPIs, Key Performance Indicator).

[0164] In some alternative embodiments, the second data corresponding to the base stations of the basic coverage type (or main function) may include at least one of the following: performance metrics related to the mobility of the user / user group, performance metrics related to the random access of the user / user group; the second data corresponding to the base stations of the supplementary hot spot type (or main function) may include the user plane measurement information of the network devices of the user / user group.

[0165] In some optional embodiments of the present invention, before the first network device obtains the first information sent by at least one first base station, the method further includes: the first network device sending a second subscription request to at least one third base station, where the second subscription request includes second subscription content and a second triggering method; the second subscription content includes status information, and the second triggering method includes periodically reporting the second subscription content; or reporting the second subscription content when a second preset triggering condition is met; the at least one third base station at least includes the second base station; receiving third information sent by the at least one third base station according to the second triggering method, where the third information includes the second subscription content.

[0166] In some optional embodiments, the status information includes at least one of the following: carrier shutdown state, channel shutdown state, cell sleep state, carrier on state, channel on state, cell activation state.

[0167] In this embodiment, the first network device requests to subscribe to the status information of at least one third base station within its coverage area. Among them, the at least one third base station includes the second base station, that is, the second base station reports the status information of the base station according to the second triggering method based on the subscription of the first network device. In other optional embodiments, the at least one third base station may also include other base stations other than the second base station, such as the first base station, that is, the first base station may also report the status information of the base station according to the second triggering method based on the subscription of the first network device.

[0168] In this embodiment, the second triggering method includes periodically reporting the second subscription content, that is, each base station reports its own status information to the first network device according to a set period. Or, the second triggering method includes reporting the second subscription content when a second preset triggering condition is met, where the second preset triggering condition may be the initialization of the base station status or the change of the base station status, that is, when the status of the third base station is initialized, the third information (that is, the status information of the base station) is sent to the first network device, or when the status of the third base station changes, for example, when switching from the first state to the second state, or from the second state to the first state, the third information (that is, the status information of the base station) is sent to the first network device.

[0169] In some optional embodiments of the present invention, before sending the second information to the second base station according to the first information, the method further includes: when the first network device determines that the second base station is in the first state, determining whether to send the second information to the second base station according to the first information, where the second information is used for the second base station to switch from the first state to the second state.

[0170] In some optional embodiments, the first state includes at least one of the following: carrier-off state, channel-off state, and cell sleep state.

[0171] In some optional embodiments, the energy-saving effect of the first state is better than that of the second state.

[0172] In this embodiment, when the first network device determines that the second base station is in the first state, for example, when it determines that the second base station is in an energy-saving state, it determines whether to send or not send the second information to the second base station according to the first information. The second information is used for the second base station to switch from the first state to the second state, that is, it determines whether to wake up the second base station according to the first information, or determines whether to switch the second base station from an energy-saving state to a non-energy-saving state.

[0173] In some optional embodiments, determining that the second base station is in the first state includes: the first network device receives the third information sent by the second base station, the third information includes the status information of the second base station, and the first network device determines that the second base station is in the first state based on the status information.

[0174] In some optional embodiments, the first network device receiving the third information sent by the second base station includes: the first network device receives the third information sent by the second base station in accordance with the second trigger mode.

[0175] In this embodiment, the first network device can obtain the status information sent by the second base station and determine that the second base station is in the first state according to the status information. In some optional embodiments, the first network device can obtain the status information sent by the second base station through the above subscription method; in other optional embodiments, the first network device can also obtain the status information sent by the second base station by periodically or aperiodically querying the second base station.

[0176] In some optional embodiments of the present invention, before the first network device obtains the first information sent by at least one first base station, the method further includes: the first network device sends a third subscription request to at least one third base station, the third subscription request includes third subscription content, and the third subscription content includes the first configuration information and the third location information of the base station; the at least one third base station includes the at least one first base station and / or the second base station; the first network device receives the fourth information sent by the at least one third base station, and the fourth information includes the third subscription content.

[0177] In some optional embodiments, the first configuration information of the base station includes one or more of the following: frequency information of the base station, bandwidth information of the base station, user information of the base station, transmit power information of the base station, mobile management parameter configuration information of the base station, access control parameter configuration information of the base station; and / or, the third location information includes one or more of the following: location information of the base station, relative location between the base station and neighboring base stations, coverage area of the base station, coverage area of neighboring base stations.

[0178] In this embodiment, the first network device requests a subscription from at least one third base station within the coverage area, subscribing to the first configuration information and the third location information of the base station. Wherein, the at least one third base station may include the above-mentioned first base station and / or second base station. That is, based on the subscription of the first network device, the first base station and / or the second base station send the first configuration information and the third location information (i.e., the fourth information) of the base station to the first network device.

[0179] In some optional embodiments of the present invention, the method further includes: the first network device creates first relationship information related to the base station according to the first configuration information and the third location information of the base station; at least the base station information, neighboring base station information, and trigger area information are included in the first relationship information.

[0180] In some optional embodiments, the trigger area information is the overlapping coverage area between the coverage area of the base station and the coverage area of neighboring base stations.

[0181] In this embodiment, before performing step 101, the first network device may create first relationship information according to the information obtained through the above subscription. The first relationship information may also be referred to as a neighboring area wake-up relationship table. The first network device may create first relationship information (or neighboring area wake-up relationship table) for each base station, so that when a certain base station needs to be woken up, the neighboring base stations related to the base station can be determined based on the first relationship information (or neighboring area wake-up relationship table) corresponding to the base station, and then a decision can be made according to the information reported by the neighboring base stations to determine whether to send the second information to the base station.

[0182] Among them, when the base station is in the second state (i.e., non-energy-saving state), its coverage area may overlap with one or more cells. In this embodiment, the first relationship information (or neighboring area wake-up relationship table) created for each base station is to create first relationship information (or neighboring area wake-up relationship table) with all the cells that have an overlapping coverage area with the base station, and the overlapping coverage area is used as the trigger area information, that is, the overlapping coverage area is used as the area for triggering the wake-up of neighboring areas.

[0183] In some optional embodiments, the method further includes: the first network device determines second data related to a user subscribed by the base station according to first configuration information of the base station, and determines a first threshold corresponding to each item of data; the first network device determines a first preset trigger condition according to at least one item of data corresponding to the base station and the first threshold corresponding to each item of data; correspondingly, the first relationship information further includes the data corresponding to the base station and the first preset trigger condition.

[0184] In this embodiment, the first network device can determine at least one item of second data corresponding to the base station according to the first configuration information of the base station, such as information about the type or main function of the base station, that is, determine at least one index or KPI corresponding to, requested by, or subscribed by the base station, and determine a first threshold corresponding to each item of data. Based on the at least one item of data corresponding to the base station and the first threshold corresponding to each item of data, a first preset trigger condition is determined. Among them, the at least one item of data corresponding to the base station and the first preset trigger condition corresponding to each item of data are added to the first relationship information.

[0185] In this embodiment, the first network device can determine a corresponding first threshold for each item of second data. When the second data is worse than the first threshold corresponding to the second data, specifically referring to the situation where relevant parameters that can bring a user experience are lower than the relevant threshold, it can be considered that the experience of users in the neighboring cell is poor, and the second base station needs to be woken up to provide better services. In practical applications, it can be that some index data or KPI values are greater than or equal to the corresponding first threshold, or some index data or KPI values are less than or equal to the corresponding first threshold. As long as it can bring a result of poor user experience, it can be considered that the user-related data is worse than the threshold corresponding to the data.

[0186] Among them, since the size of each overlapping coverage area, the performance of neighboring cells, etc. all affect the data related to waking up (such as KPI), the first network device can set or determine different first thresholds corresponding to the data for each neighboring cell according to the first configuration information of the base station and the neighboring cell, the relative position information between the base station and the neighboring cell, and according to set rules, algorithms or engineering experience.

[0187] In some optional embodiments, the first threshold is an absolute value, and / or, the first preset trigger conditions corresponding to at least two items of data have an association relationship.

[0188] In this embodiment, the absolute value is relative to the relative value. The absolute value may be a positive number, a negative number, or zero. For example, UL MCS > 0, RLF rate > 0, etc. In addition, the first preset trigger conditions corresponding to at least two items of data have an associated relationship, which may be a conditional association relationship, a relative association relationship, etc. For example, when Uplink Buffer Status > 1000Byte, UL THP < 1000kbps, etc.

[0189] In some alternative embodiments, the first relationship information further includes a second threshold corresponding to the base station; wherein the second threshold is used to determine whether to send or not send the second information to the second base station.

[0190] In some alternative embodiments, the first relationship information further includes a conversion relationship for converting the second data and the first threshold corresponding to each item of data into a factor.

[0191] In this embodiment, the dimensions of the data (or KPIs, metric data, etc.) and the impact on the user experience are different. It is necessary to perform conversion processing on the data (or KPIs, metric data, etc.) of the neighboring cells, such as normalization processing and / or weighting processing, etc. Finally, a factor (or can be called a wake-up factor, wake-up impact factor, etc.) is obtained by synthesizing multiple items of data (or KPIs, metric data, etc.) to determine whether to wake up the second base station. At the same time, for the second base station to be woken up, the more the data related to triggering the wake-up exceeds the threshold, the more it affects the user experience, which indicates that this second base station should be woken up more.

[0192] For example, it can be designed that the conversion coefficient a_mcs of MCS[0 - 28] and the wake-up impact factor is 1 / 28, and the measured MCS is converted into a wake-up impact factor of (MCS threshold - MCS) * a_mcs; it can be designed that the conversion relationship between THP (throughput) and the wake-up impact factor is (THP threshold - THP) / THP threshold; therefore, the wake-up impact factor of user 1 on the site can be expressed as: (MCS threshold - MCS) * a_mcs + (THP threshold - THP) / THP threshold.

[0193] Furthermore, a weight coefficient e_VIP can be designed to increase the wake-up impact factor. For example, the above measured MCS and THP are converted into a wake-up impact factor of [(MCS threshold - MCS) * a_mcs + (THP threshold - THP) / THP threshold] * e_VIP, where e_VIP > 1, which will increase the influence of this user on waking up the site. In the actual application process, for important users (such as VIP users), the factor increase process can be performed, that is, a weight coefficient is designed for important users.

[0194] In this embodiment, for the second base station to be woken up, within the geographical area (i.e., the triggering area) where wake-up is triggered, the more users expected to be woken up, the greater the total factor, and the more likely the second base station should be woken up. Based on this, the first network device sets the second threshold corresponding to this base station, adds up the factors corresponding to all users in the neighboring area to obtain the total factor, and if the total factor exceeds (or is greater than or equal to) this second threshold, then this base station can be woken up. In other alternative embodiments, when there are two or more base stations to be woken up exceeding the threshold in the co-covered area, the first network device determines to preferentially wake up the base station with the largest total factor, or determines to preferentially wake up N base stations whose total factors are ranked among the top N, where N is a positive integer; among them, the total factor ranking is sorted from largest to smallest.

[0195] In some alternative embodiments, the first network device sends a first subscription request to at least one third base station based on the first relationship information (or the neighboring area wake-up relationship table), specifically sending the first subscription request to the third base station based on the second data in the first relationship information and the first preset triggering condition.

[0196] Exemplarily, the content of the first relationship information (or the neighboring area wake-up relationship table) of the base station can refer to the example shown in Table 2 below.

[0197] Table 2

[0198]

[0199]

[0200] In this embodiment, the first network device can determine that the cell where the at least one first base station is located is a neighboring area of the second base station according to the first relationship information, or the at least one first base station and the second base station are neighboring base stations to each other; furthermore, the first network device determines whether to send the second information to the second base station according to the first information. In some alternative embodiments, the method further includes: the first network device determines that the cell where the at least one first base station is located is a neighboring area of the second base station according to the first relationship information.

[0201] In this embodiment, the first network device can determine the neighboring area relationship between base stations according to the created first relationship information, that is, determine that the cell where the at least one first base station is located is a neighboring area of the second base station. In other alternative embodiments, the first network device can also determine the neighboring area relationship between base stations according to the received fourth information (or the third subscription content, or the first configuration information and the third location information of the base station, etc.), that is, determine that the cell where the at least one first base station is located is a neighboring area of the second base station.

[0202] In some optional embodiments, determining whether to send or not send the second information to the second base station according to the first information includes: the first network device screens the first information according to the first trigger area information related to the second base station to obtain the first data of the first user satisfying the first trigger area information; the first user is any user in the first information whose first location information satisfies the first trigger area information; the first network device performs conversion processing on the first data of the first user to obtain a first factor; the first network device adds up the first factors corresponding to all the first users satisfying the first trigger area information to obtain a first value; the first network device compares the first value with a second threshold related to the second base station, and determines whether to send or not send the second information to the second base station according to the comparison result.

[0203] In this embodiment, after receiving the first information sent by at least one first base station, the first network device can determine all the first trigger areas related to the second base station according to the first relationship information, that is, determine the overlapping areas of all the neighboring areas of the second base station, and then screen the reported data according to the first trigger area to obtain the first data of the first user satisfying the first trigger area information; where the first user refers to any user among all the users satisfying the first trigger area, that is, obtain the first data of all the users satisfying the first trigger area information. Further, the first network device can perform conversion processing on the first data of each first user according to the "factor" (or conversion relationship) in the first relationship information to obtain the first factor corresponding to each first user, and add up the first factors corresponding to all the first users satisfying the first trigger area information to obtain a first value. Finally, compare the first values of all the first users with the second threshold corresponding to the second base station, and determine whether to send or not send the second information to the second base station according to the comparison result.

[0204] In some optional embodiments, the first network device performs conversion processing on the first data of the first user to obtain a first factor, including: the first network device adds up the first data of each item of the first user after conversion according to the corresponding conversion relationship to obtain a first factor.

[0205] In some optional embodiments, the first network device adds up the first data of each item of the first user after conversion according to the corresponding conversion relationship to obtain a first factor, including: the first network device adds up the first data of each item of the first user after conversion according to the corresponding conversion relationship, and multiplies the added data by the first weight corresponding to the first user to obtain a first factor.

[0206] In this embodiment, the conversion processing of the first data of each first user by using the "factor" (or conversion relationship) in the first relationship information is as follows: For example, it is possible to design the conversion coefficient a_mcs between MCS[0-28] and the wake-up influence factor as a_mcs = 1 / 28, and convert the measured MCS into the wake-up influence factor as (MCS threshold - MCS) * a_mcs; it is possible to design the conversion relationship between THP and the wake-up influence factor as (THP threshold - THP) / THP threshold; therefore, the first factor of the first user can be expressed as: (MCS threshold - MCS) * a_mcs + (THP threshold - THP) / THP threshold.

[0207] Alternatively, the first user has a first weight, for example, denoted as the weight coefficient e_VIP, to increase the influence of the factor on network energy-saving wake-up. Then, the measured MCS and THP are converted into the wake-up influence factor as [(MCS threshold - MCS) * a_mcs + (THP threshold - THP) / THP threshold] * e_VIP, where e_VIP > 1, which will increase the influence of this first user on the wake-up site.

[0208] In some alternative embodiments, determining whether to send the second information to the second base station according to the comparison result includes: when the comparison result is that the first value is greater than or equal to the second threshold, determining to send the second information to the second base station; when the comparison result is that the first value is less than the second threshold, determining not to send the second information to the second base station.

[0209] In this embodiment, after adding up the first factors of all first users to obtain a first value, comparing the first value with the second threshold in the first relationship information. If the first value is greater than or equal to the second threshold, it can indicate that there are more users with poor user experience or more users expecting the base station to wake up, and the second base station should be woken up more; correspondingly, if the first value is less than the second threshold, it can indicate that there are fewer users with poor user experience or fewer users expecting the base station to wake up, and the second base station does not need to be woken up currently.

[0210] In some alternative embodiments of the present invention, when the first network device is the intelligent control platform in the O-RAN system, the first network device communicates with the base station through the E2 interface; or, when the first network device is a control base station, the first network device communicates with the base station through the X2 interface.

[0211] Based on the above embodiments, the embodiments of the present invention further provide a network energy-saving wake-up method. Figure 2 It is a schematic flow of the network energy-saving wake-up method of the embodiments of the present invention Figure 2 ; as Figure 2 shown, the method includes:

[0212] Step 201: The first base station sends first information to the first network device. The first information at least includes first data related to a user and the first location information of the user. The first information is used for the first network device to send second information for network energy-saving wake-up to the second base station.

[0213] In this embodiment, there is an association relationship between the first base station and the second base station. In some optional embodiments, the association relationship may at least include: the coverage areas of the first base station and the second base station have an overlapping coverage area, or the cell where the first base station is located and the cell where the second base station is located can be neighboring cells to each other, or the first base station and the second base station can be neighboring base stations to each other.

That is, network energy-saving wake-up is performed in a cooperative manner, that is, the base station is woken up with data and location related to users in neighboring cells, comprehensively considering the user experience in neighboring cells and the user experience. Without affecting the energy-saving effect of the base station, the user experience is guaranteed.

[0220] In some optional embodiments, the second information includes at least one of the following: an indication information for carrier activation or wake-up, an indication information for channel activation or wake-up, an indication information for cell activation or wake-up.

[0221] In some optional embodiments of the present invention, before the first base station sends the first information to the first network device, the method further includes: the first base station receives a first subscription request sent by the first network device, where the first subscription request includes a first subscription content and a first triggering manner; the first subscription content includes second data related to the user and the second location information of the user; the first triggering manner includes periodically reporting the first subscription content; or reporting the first subscription content when a first preset triggering condition is met.

[0222] In some optional embodiments, the first base station sending the first information to the first network device includes: the first base station sending the first information to the first network device according to the first triggering manner.

[0223] In this embodiment, the first network device requests a subscription from at least one base station within its coverage area for subscribing to second data related to the user and the second location information of the user. Among them, the at least one base station includes the first base station, that is, the first base station reports the first information to the first network device according to the first triggering manner based on the subscription of the first network device.

[0224] In some optional embodiments, the data types included in the second data include the data types included in the first data. Exemplarily, the second data may include N data (or data types), and the first data may include M data (or data types), where M is less than or equal to N. It can be understood that the first base station may determine the first data to be reported to the first network device according to the content in the first subscription request and based on the second data.

[0225] In this embodiment, the first triggering method includes periodically reporting the first subscription content, that is, the first base station reports the collected or measured first subscription content (i.e., the first information) to the first network device according to a set period. Alternatively, the first triggering method is to report the first subscription content when a first preset triggering condition is met, where the first preset triggering condition may be that the second data related to the user (or the second data subscribed by the base station) is worse than the first threshold corresponding to the second data, or the relative relationship between two or more second data related to the user.

[0226] Among them, the situation that the second data related to the user is worse than the first threshold corresponding to the second data specifically refers to the case where the relevant parameters that can bring the user experience are lower than the relevant threshold. That is, it can be considered that the experience of the neighboring cell user is poor, and the second base station needs to be woken up to provide better services. In practical applications, it may be that some metric data or KPI values are greater than or equal to the corresponding first threshold, or some metric data or KPI values are less than or equal to the corresponding first threshold. As long as it can bring the result of poor user experience, it can be considered that the user-related data is worse than the first threshold corresponding to the second data. For example, UL MCS > 0, RLF rate > 0, etc. Also, for example, the first preset triggering condition may be the relative relationship between two or more user-related data, such as when Uplink Buffer Status > 1000Byte, UL THP < 1000kbps, etc.

[0227] In some optional embodiments, the second data related to the user includes one or more of the following: the user plane measurement information of the network device of the user / user group; the performance metrics related to the mobility of the user / user group; the performance metrics related to the random access of the user / user group.

[0230] The performance metrics related to the random access of the user / user group may include one or more of the following: information related to random access channel failure (RACH Failure); information related to radio link failure (Radio Link Failure); information related to UE context release (UE CONTEXT Release). Exemplarily, the information related to random access channel failure (RACH Failure) may include, but is not limited to, one or more of the following information: the number of RACH failures, the RACH failure rate, the RACH cause, the number of RACH retries, etc. The information related to RLF may include, but is not limited to, one or more of the following information: the number of RLF occurrences, the failure rate.

[0231] In some alternative embodiments, the second location information includes, but is not limited to, Location and Velocity measurements. Exemplarily, the second location information may include, but is not limited to, one or more of the following information: AOA, longitude and latitude information, TOA information, altitude information, velocity, etc.

[0232] In this embodiment, for different base station types or the main functions of the base stations, the user-related data in the first subscription request sent by the first network device may be different. For example, for a base station of the basic coverage type or function, the user-related data for this type or function may be sent; for a base station of the supplementary hot spot type or function, the user-related data for this type or function may be sent. Alternatively, the first network device may also send the same user-related data in the first subscription request for all base stations within the coverage area, that is, send the same subscription content; after receiving the first subscription request, each base station (including the first base station) collects and reports the same metric data or KPIs, or after receiving the first subscription request, each base station (including the first base station) selects the metric data or KPIs to be reported according to its own type or function. This embodiment does not limit this.

[0233] In some optional embodiments of the present invention, before the first base station sends the first information to the first network device, the method further includes: the first base station receives a third subscription request sent by the first network device, where the third subscription request includes third subscription content, and the third subscription content includes the first configuration information of the base station and the third location information.

[0234] In some optional embodiments, the first configuration information of the base station includes one or more of the following: the frequency information of the base station, the bandwidth information of the base station, the user information of the base station, the transmit power information of the base station, the mobile management parameter configuration information of the base station, the access control parameter configuration information of the base station; and / or, the third location information includes one or more of the following: the location information of the base station, the relative position between the base station and neighboring base stations, the coverage area of the base station, the coverage area of neighboring base stations.

[0235] In this embodiment, the first network device requests subscriptions from at least one base station (including the first base station) within its coverage area for the configuration information and location information of the base stations. Based on the subscription of the first network device, the first base station sends the first configuration information of the base station and the third location information (i.e., the fourth information) to the first network device.

[0236] Among them, the configuration information of the base station may include the configuration of the base station and / or neighboring cells; among them, the configuration of the base station and / or neighboring cells may at least include the type or function of the base station and neighboring cells. The location information of the base station may include information such as the absolute location of the base station, the relative position between the base station and neighboring cells, etc.

[0237] In some optional embodiments of the present invention, when the first network device is the intelligent control platform in the O-RAN system, communication and interaction between the first network device and the first base station are carried out through the E2 interface; or, when the first network device is a control base station, communication and interaction between the first network device and the first base station are carried out through the X2 interface.

[0238] Based on the above embodiments, an embodiment of the present invention further provides a method for network energy-saving wake-up.

[0241] In this embodiment, before step 301 is executed, the second base station is in an energy-saving state, which can be, for example, the low-traffic energy-saving state, the shallow sleep state or the deep sleep state recorded in Table 1, or the coverage area of the second base station is an area with reduced or disappeared coverage. Exemplarily, when the second base station is in the low-traffic energy-saving state, since some transmit radio frequency channels are turned off (or in the sleep state), the first information can be sent to the first network device through the partially turned-on transmit radio frequency channels. When the second base station is in the shallow sleep state or the deep sleep state, since analog devices such as power amplifiers and transceivers are turned off, the first information cannot be sent to the first network device.

[0242] Then in some alternative embodiments, the at least one first base station includes the at least one second base station or the neighboring area of the second base station.

[0243] In the embodiment of the present invention, the first network device formulates a wake-up strategy based on the first data of the user and the first location information of the user sent by the first base station, and sends the second information for network energy-saving wake-up to the second base station, that is, network energy-saving wake-up is performed in a cooperative manner, comprehensively considering the user experience of neighboring areas, and ensuring the user experience without affecting the energy-saving effect of the base station.

[0249] In some optional embodiments, the second information includes at least one of the following: an indication information for carrier activation or wake-up, an indication information for channel activation or wake-up, an indication information for cell activation or wake-up.

[0250] In this embodiment, the second information is used for energy-saving wake-up, that is, to indicate or cause the second base station to switch from the first state to the second state. The first state may be an energy-saving state, and the second state may be a non-energy-saving state. Or, the energy-saving effect of the first state is better than that of the second state.

[0251] In some optional embodiments, the first state includes at least one of the following: carrier-off state, channel-off state, cell sleep state. The second state includes at least one of the following: carrier-on state, channel-on state, cell activation state, etc.

[0252] In some optional embodiments of the present invention, before the second base station receives the second information sent by the first network device, the method further includes: the second base station receives a first subscription request sent by the first network device, where the first subscription request includes first subscription content and a first triggering method; the first subscription content includes second data related to the user and the second location information of the user; the first triggering method includes reporting the first subscription content periodically; or reporting the first subscription content when a first preset triggering condition is satisfied; the second base station sends the first information to the first network device according to the first triggering method.

[0253] In this embodiment, the first network device requests subscriptions from at least one base station within its coverage area for subscribing to second data related to the user and the second location information of the user. Among them, the at least one base station includes the second base station, that is, based on the subscription of the first network device, the second base station reports the first information to the first network device according to the first triggering method.

[0254] In some optional embodiments, the data types included in the second data include the data types included in the first data. Exemplarily, the second data may include N data (or data types), and the first data may include M data (or data types), then M is less than or equal to N. It can be understood that the second base station can determine the first data to be reported to the first network device from the second data according to the content in the first subscription request.

[0255] In this embodiment, the first triggering method includes reporting the first subscription content periodically, that is, the second base station reports the first subscription content (i.e., the first information) collected or measured to the first network device according to a set period. Or, the first triggering method is to report the first subscription content when a first preset triggering condition is satisfied, where the first preset triggering condition may be that the second data related to the user (or the second data subscribed by the base station) is worse than the first threshold corresponding to the second data, or the relative relationship between two or more second data related to the user.

[0256] Among them, the second user-related data is worse than the first threshold corresponding to the second data, specifically referring to the situation where the relevant parameters that can bring user experience are lower than the relevant threshold. That is, it can be considered that the experience of neighboring cell users is poor, and the second base station needs to be woken up to provide better services. In practical applications, it can be that some metric data or KPI values are greater than or equal to the corresponding first threshold, or some metric data or KPI values are less than or equal to the corresponding first threshold. As long as it can bring a poor user experience result, it can be considered that the user-related data is worse than the first threshold corresponding to the second data. For example, UL MCS > 0, RLF rate > 0, etc. Another example is that the first preset trigger condition can be the relative relationship between two or more user-related data, such as when Uplink Buffer Status > 1000Byte, UL THP < 1000kbps, etc.

[0257] In some optional embodiments, the second user-related data includes one or more of the following: user plane measurement information of the network device of the user / user group; performance indicators related to the mobility of the user / user group; performance indicators related to the random access of the user / user group.

[0258] Exemplarily, the user plane measurement information of the network device of the user / user group may include one or more of the following: average uplink or downlink throughput; uplink or downlink PRB utilization rate; uplink or downlink data cache information, uplink or downlink block error rate (BLER), uplink or downlink MCS, etc.

[0259] The performance indicators related to the mobility of the user / user group may include, but are not limited to, information related to handover failure (HandoverFailure). For example, the information related to handover failure may be: the number of handover failures related to MRO (Numberof handover failures related with MRO). Exemplarily, the information related to handover failure may include, but is not limited to, the handover failure rate.

[0260] The performance indicators related to the random access of the user / user group may include one or more of the following: information related to random access channel failure (RACH Failure); information related to radio link failure (Radio Link Failure); information related to UE context release (UE CONTEXT Release). Exemplarily, the information related to random access channel failure (RACHFailure) may include, but is not limited to, one or more of the following information: the number of RACH failures, the RACH failure rate, the RACH reason, the number of RACH retries, etc. The information related to RLF may include, but is not limited to, one or more of the following information: the number of RLF occurrences, the failure rate.

[0261] In some optional embodiments, the second location information includes, but is not limited to, Location and Velocity measurements. Exemplarily, the second location information may include, but is not limited to, one or more of the following information: Angle of Arrival (AOA) information, longitude and latitude information, Time of Arrival (TOA) information, altitude information, velocity, etc.

[0262] In some optional embodiments of the present invention, before the second base station receives the second information sent by the first network device, the method further includes: the second base station receives a second subscription request sent by the first network device, where the second subscription request includes second subscription content and a second triggering manner; the second subscription content includes status information, and the second triggering manner includes periodically reporting the second subscription content; or reporting the second subscription content when a second preset triggering condition is met; the second base station sends a third information to the first network device according to the second triggering manner, where the third information includes the status information of the second base station.

[0263] In some optional embodiments, the status information includes at least one of the following: carrier off state, channel off state, cell sleep state, carrier on state, channel on state, cell activation state.

[0264] In this embodiment, the first network device requests subscriptions from at least one base station (including the second base station) within its coverage area for the status information of the subscribed base stations. The second base station reports the status information of the base station to the first network device according to the second triggering manner based on the subscription of the first network device.

[0265] In this embodiment, the second triggering manner includes periodically reporting the second subscription content, that is, the second base station reports its own status information to the first network device according to a set period. Or, the second triggering manner includes reporting the second subscription content when a second preset triggering condition is met, where the second preset triggering condition may be the initialization of the base station status or the change of the base station status. That is, when the status of the second base station is initialized, the third information (i.e., the status information of the base station) is sent to the first network device, or when the status of the second base station changes, such as switching from the first state to the second state, or from the second state to the first state, the third information (i.e., the status information of the base station) is sent to the first network device.

[0266] In some optional embodiments of the present invention, before the second base station receives the second information sent by the first network device, the method further includes: the second base station receives a third subscription request sent by the first network device, the third subscription request includes third subscription content, and the third subscription content includes the first configuration information of the base station and the third location information; the second base station sends fourth information to the first network device, and the fourth information includes the third subscription content.

[0267] In some optional embodiments, the first configuration information of the base station includes one or more of the following: the frequency information of the base station, the bandwidth information of the base station, the user information of the base station, the transmit power information of the base station, the mobile management parameter configuration information of the base station, the access control parameter configuration information of the base station; and / or, the third location information includes one or more of the following: the location information of the base station, the relative position between the base station and the neighboring base station, the coverage area of the base station, the coverage area of the neighboring base station.

[0268] In this embodiment, the first network device requests subscriptions from at least one base station (including the second base station) within its coverage area for the first configuration information and the third location information of the base station. Based on the subscription of the first network device, the second base station sends the first configuration information and the third location information (i.e., the fourth information) of the base station to the first network device.

[0269] In some optional embodiments of the present invention, when the first network device is the intelligent control platform in the O-RAN system, communication and interaction between the first network device and the second base station are carried out through the E2 interface; or, when the first network device is a control base station, communication and interaction between the first network device and the second base station are carried out through the X2 interface.

[0270] The technical solutions of the embodiments of the present invention will be described in detail below with specific examples.

[0271] Step 1, select a first network device to construct the first relationship information or the neighbor wake-up relationship table. The first relationship information or the neighbor wake-up relationship table can be referred to Table 2 and includes the base station to be woken up, neighboring areas, trigger wake-up areas (optional), wake-up related data (or metric data, KPIs, etc.) / trigger conditions, the conversion relationship for converting the data into wake-up factors, and the second threshold of the base station, etc.

[0272] Specifically, Figure 4 is a schematic flowchart of creating the first relationship information in the network energy-saving wake-up method of the embodiment of the present invention; as Figure 4 shown, the method includes:

[0273] Step 401: Obtain the configuration information and location information of the base station, and determine the wake-up trigger area based on the configuration information and location information of the base station.

[0274] Here, the area information corresponding to the wake-up trigger area may be equivalent to the trigger area information in the above embodiment. The configuration information is equivalent to the first configuration information in the above embodiment, and the position information is equivalent to the third position information in the above embodiment.

[0275] In this example, when the base station is in the second state (i.e., the non-energy-saving state), its coverage area may overlap with one or more cells. In this embodiment, the first relationship information (or neighbor cell wake-up relationship table) created for each base station is the first relationship information (or neighbor cell wake-up relationship table) created with all the cells in the overlapping coverage area of the base station, and the overlapping coverage area is used as the trigger area information, that is, the overlapping coverage area is used as the area for triggering the wake-up of the corresponding neighbor cell.

[0276] Step 402: Determine the main function or type of the base station, and define the metric data according to the main function or type of the base station.

[0277] In this example, the first network device can determine at least one piece of metric data corresponding to the base station according to the configuration information of the base station, such as information about the type or main function of the base station.

[0278] Step 403: The first network device determines the first threshold corresponding to each piece of metric data, and determines the trigger condition according to at least one piece of metric data corresponding to the base station and the first threshold corresponding to each piece of metric data.

[0279] Here, the trigger condition may specifically be the first preset trigger condition in the above embodiment. The metric data may be equivalent to the second data in the above embodiment.

[0280] In this example, the first network device can determine the corresponding first threshold for each piece of metric data. When the metric data is worse than the first threshold corresponding to the metric data, specifically referring to the situation where the relevant parameters that can bring the user experience are lower than the relevant threshold, it can be considered that the experience of the neighbor cell users is poor, and the second base station needs to be woken up to provide better services. In practical applications, that the metric data is worse than the first threshold corresponding to the metric data may mean that some metric data or KPI values are greater than or equal to the corresponding first threshold, or some metric data or KPI values are less than or equal to the corresponding first threshold. As long as it can bring a poor user experience result, it can be considered that the user-related data is worse than the threshold corresponding to the data.

[0281] Among them, since the size of each overlapping coverage area, the performance of the neighbor cell, etc. all affect the wake-up-related data (such as KPI), the first network device can set or determine different first thresholds corresponding to the data for each neighbor cell according to the configuration information of the base station and the neighbor cell, the relative position information between the base station and the neighbor cell, and according to the set rules, algorithms or engineering experience.

[0282] In some optional embodiments, the first threshold is an absolute value corresponding to the metric data, and / or the trigger conditions corresponding to at least two metric data have an association relationship. Here, the absolute value is relative to the relative value, and the absolute value may be a positive number, a negative number, or zero. For example, UL MCS > 0, RLF rate > 0, etc. In addition, the trigger conditions corresponding to at least two metric data have an association relationship, and the association relationship may be a conditional association relationship, a relative association relationship, etc. For example, when Uplink Buffer Status > 1000Byte, UL THP < 1000kbps, etc.

[0283] Step 404: The first network device determines the conversion relationship between the metric data and the wake-up impact factor, and determines the second threshold corresponding to the base station.

[0284] Here, the wake-up impact factor can be equivalent to the factor in the above embodiments.

[0285] In this example, the dimensions of the metric data and the impact on the user experience are different. It is necessary to perform conversion processing on the metric data of neighboring cells, such as normalization processing and / or weighting processing, etc. Finally, the wake-up impact factor is obtained by synthesizing multiple metric data to decide whether to wake up the base station. At the same time, for the base station to be woken up, the more the metric data related to the wake-up exceeds the threshold, the more it affects the user experience, indicating that the base station should be woken up more.

[0286] For example, it can be designed that the conversion coefficient a_mcs between MCS[0 - 28] and the wake-up impact factor is 1 / 28, and the measured MCS is converted into the wake-up impact factor as (MCS threshold - MCS) * a_mcs; the conversion relationship between THP and the wake-up impact factor can be designed as (THP threshold - THP) / THP threshold; therefore, the wake-up impact factor of user 1 on the site can be expressed as: (MCS threshold - MCS) * a_mcs + (THP threshold - THP) / THP threshold.

[0287] Furthermore, a weight coefficient e_VIP can be designed to increase the wake-up impact factor. For example, the above measured MCS and THP are converted into the wake-up impact factor as [(MCS threshold - MCS) * a_mcs + (THP threshold - THP) / THP threshold] * e_VIP, where e_VIP > 1, which will increase the influence of this user on waking up the site. In the actual application process, for important users (such as VIP users), the factor increase process can be performed, that is, a weight coefficient is designed for important users.

[0288] In this example, for the base station to be woken up, within the geographical area where wake-up is triggered (i.e., the trigger area), the more users expect to be woken up, the larger the total factor, and the more likely the base station should be woken up. Based on this, the first network device sets the second threshold corresponding to the base station, adds up the factors corresponding to all users in the neighboring cells to obtain the total factor. If the total factor exceeds (or is greater than or equal to) the second threshold, the base station can be woken up. In other alternative embodiments, when there are two or more base stations to be woken up exceeding the threshold in the co-covered area, the first network device determines to preferentially wake up the base station with the largest total factor, or determines to preferentially wake up N base stations whose total factors are ranked among the top N, where N is a positive integer; among them, the total factor ranking is sorted from largest to smallest.

[0289] Step 405: The first network device generates a neighboring cell wake-up relationship table corresponding to the base station. The generated neighboring cell wake-up relationship table can be referred to as shown in Table 2 above.

[0290] Here, the neighboring cell wake-up relationship table can be equivalent to the first relationship information in the above embodiment.

[0291] Figures 5a to 5c It is an application schematic diagram for creating the first relationship information in the network energy-saving wake-up method of the embodiment of the present invention.

[0292] In the existing network, there are various wireless network systems. TD-LTE is mainly divided into three frequency bands: F / A band (outdoor), D band (outdoor), E (indoor). The F band has frequency points 38400, 38544, 38496, the A band has frequency point 36275, the D band has frequency points 40936, 41134, and the E band has frequency points 38950, 39148, 39292. The frequency bands of FDD-LTE mainly include the 900M low-frequency band for expanding the coverage level of TD-LTE, and the 1800MHz high-frequency band as a means to supplement the capacity in hot spots. NR mainly has the 700M low-frequency band for wide coverage, and the 2.6G high-frequency band for providing high-capacity transmission capabilities in hot spots.

[0293] In different scenarios such as the main urban area, county, and rural areas, different network topologies are designed in the existing network to meet the requirements of different scenarios. As Figure 5a shown:

[0294] For example, in the main urban area, it is mainly 700M + FDD1800 + F / D bands, achieving wide coverage through 700M, FDD1800, and F / D bands, and supplementing hot spot coverage through multi-carrier aggregation of 2.6G and F / D bands of 5G and the E band;

[0295] For example, in towns and townships, the main frequency bands are 700M + FDD1800 / FDD900 + F / D bands. Wide coverage is achieved through 700M, FDD1800 / FDD900, and F / D bands, and multi-carrier aggregation of the F / D band and E-band supplementation are used to cover hotspots.

[0296] For example, in rural areas, the main frequency bands are 700M + FDD900 + F / D bands. Wide coverage is achieved through 700M, FDD900, and F / D bands, and multi-carrier aggregation of the F / D band is used to cover hotspots.

[0297] Therefore, taking the main urban area scenario as an example, the base stations for basic coverage wake up the base stations for supplementing hotspot capacity. For example, FDD1800 wakes up 2.6G, 700M wakes up 2.6G, and 2.6G / 700M / FDD1800M wakes up the indoor E-band.

[0298] Taking the rural scenario as an example, there are also cases where the base stations for basic coverage are woken up. For example, the D-band / F-band wakes up FDD900.

[0299] Taking the creation of the neighbor cell wake-up relationship table for the base stations supplementing hotspots as an example, the frequency bands of the base stations supplementing hotspots are relatively high, and the frequency bands of the neighbor cells for basic coverage are relatively low. When the high-frequency base station is in the non-energy-saving state and its coverage area overlaps with one or more cells, all the cells with overlapping coverage are taken as neighbor cells, and the overlapping coverage area is taken as the geographical area where the corresponding neighbor cell triggers wake-up.

[0300] As Figure 5b shown in (1) of [], the 2.6G site provides high-capacity transmission capabilities for hotspots, and its coverage area overlaps with several FDD1800 sites. Then its neighbor cell wake-up relationship includes: when the 2.6G site is in the energy-saving state, the main serving cell of UE-1 is one of the FDD1800 base stations. In the area overlapping with the 2.6G site, since it exceeds the corresponding first threshold and thus meets the trigger condition, the part exceeding the first threshold is converted into a wake-up impact factor, which is used to increase the possibility of waking up the cell built by the 2.6G site.

[0301] As Figure 5b shown in (2) of [], the 2.6G site provides high-capacity transmission capabilities for hotspots, and its coverage area overlaps with 1 700M site. Then its neighbor cell wake-up relationship includes: when the 2.6G site is in the energy-saving state, the main serving cell of UE-2 is at the 700M site. In the area overlapping with the 2.6G site, since it exceeds the corresponding first threshold and thus meets the trigger condition, the part exceeding the first threshold is converted into a wake-up impact factor, which is used to increase the possibility of waking up the cell built by the 2.6G site.

[0302] As Figure 5bIn (3), the E-band site provides indoor high-capacity transmission capabilities. Its coverage area overlaps with that of one 700M site and one 2.6G site. Then its neighbor cell wake-up relationship includes: when the E-band site is in the energy-saving state, the primary serving cell of UE-3 is in the 700M site. In the area overlapping with the E-band site, since it exceeds the corresponding first threshold and thus meets the trigger condition, the part exceeding the first threshold is converted into a wake-up impact factor. The primary serving cell of UE-4 is in the 2.6G site. In the area overlapping with the E-band site, since it exceeds the corresponding first threshold and thus meets the trigger condition, the part exceeding the first threshold is converted into a wake-up impact factor. The wake-up impact factors of the two users, UE-3 and UE-4, are added together to increase the possibility of waking up the cell built by the E-band site.

[0303] In the above example, KPIs related to performance can be used, such as UL THP, UPlink Buffer Status, ULMCS, UL BLER, UL PRB utilization rate, DL THP, DL MCS, Downlink Buffer Status, DL BLER, DL PRB utilization rate, and so on.

[0304] Taking the creation of a neighbor cell wake-up relationship table for a base station with basic coverage as an example, when the traffic volume and the number of users of the base station are extremely small, it enters the energy-saving state. When the base station with basic coverage is in the non-energy-saving state, its coverage area overlaps with one or more cells. Then all the cells with basic coverage in the overlapping area are taken as neighbor cells, and the overlapping area is taken as the geographical area for triggering the wake-up of the corresponding neighbor cells.

[0305] As Figure 5c shown, the main function of the FDD900 site is to provide a site with basic coverage. Its coverage area overlaps with one 700M site and another FDD900 site. Then its neighbor cell wake-up relationship includes: when the FDD900 site is in the energy-saving state, the primary serving cell of UE-5 is in the 700M site. In the area overlapping with the FDD900 site, since it exceeds the corresponding first threshold and thus meets the trigger condition, the part exceeding the first threshold is converted into a wake-up impact factor. The primary serving cell of UE-6 is in the FDD900 site. In the area where the two FDD900 sites overlap, since it exceeds the corresponding first threshold and thus meets the trigger condition, the part exceeding the first threshold is converted into a wake-up impact factor. The wake-up impact factors of the two users, UE-5 and UE-6, are added together to increase the possibility of waking up the cell built by the FDD900 site.

[0306] For the neighbor cell wake-up relationship of the base station with basic coverage, KPIs related to coverage metrics can be used, such as HOFrate, HO ping pong, RLF, random access failure rate, RSRP, SINR, and so on.

[0307] Step 2, the first network device subscribes to the status information of the base station.

[0308] Specifically, Figure 6 is a schematic diagram of a subscription process in the network energy-saving wake-up method of this embodiment of the present invention; as Figure 6 shown, the method includes:

[0309] Step 501: The first network device sends a subscription request to the base station, and the subscription object is the base stations within its jurisdiction. The subscription request includes subscription content and a trigger method; wherein, the subscription content is the status information of the base station, and the trigger method includes periodically reporting the subscription content; or, reporting the subscription content when a second preset trigger condition is met, such as reporting the status information when the base station deployment is initialized or the base station status changes.

[0310] Step 502: The base station feedbacks the information of successful subscription, and the first network device learns that the base station has accepted the subscription request.

[0311] Step 503: The base station detects the trigger condition, whether it is deployment initialization or status change.

[0312] Step 504: After detecting that the trigger condition occurs, the base station reports the subscription content to the first network device, including the base station ID and the status information of the base station.

[0313] The subscription process in this example is equivalent to the second subscription process in the above embodiment, and at least includes the process of the first network device sending a second subscription request to at least one third base station and receiving the third information sent by at least one third base station.

[0314] Exemplarily, the code implementation of the above subscription request content can be referred to as follows:

[0315]

[0316]

[0317] Step 3, the first network device subscribes to the user data and user location information that trigger energy-saving wake-up.

[0318] Specifically, Figure 7 is another schematic diagram of a subscription process in the network energy-saving wake-up method of this embodiment of the present invention; as Figure 7 shown, the method includes:

[0319] Step 601: The first network device sends a subscription request to the base station. The subscription object is the base stations within the jurisdiction area. The subscription request includes subscription content and a triggering method. The subscription content includes user-related metric data and the location information of the user. The triggering method includes reporting the subscription content periodically; or reporting the subscription content when a first preset triggering condition is met.

[0320] Here, reporting the subscription content when the first preset triggering condition is met may specifically refer to that the user-related metric data is worse than the threshold corresponding to the metric data, or the relative relationship between two or more user-related data.

[0321] Among them, the user-related data being worse than the threshold corresponding to the data specifically refers to the situation where the relevant parameters that can bring the user experience are lower than the relevant threshold. That is, it can be considered that the experience of the neighboring area users is poor, and the second base station needs to be woken up to provide better services. In practical applications, it can be that some metric data or KPI values are greater than or equal to the corresponding threshold, or some metric data or KPI values are less than or equal to the corresponding threshold. As long as it can bring a poor user experience result, it can be considered that the user-related data is worse than the threshold corresponding to the data. For example, UL MCS > 0, RLF rate > 0, etc. Another example is that the first preset triggering condition can be the relative relationship between two or more user-related data, such as when Uplink Buffer Status > 1000Byte, UL THP < 1000kbps, etc.

[0322] Exemplarily, for base stations of the supplementary hotspot type, the metric data related to performance is corresponding, such as UL THP, UPlink Buffer Status, UL MCS, DL THP, DL MCS, Downlink Buffer Status, etc.; for base stations of the basic coverage type, the metric data related to coverage is corresponding, such as HOF, HO ping pong, RLF, random access failure rate, etc.

[0323] Step 602: The base station feeds back the information of successful subscription, and the first network device learns that the base station has accepted the subscription request.

[0324] Step 603: The base station detects the triggering condition, such as detecting that the metric data is worse than the threshold.

[0325] Step 604: After detecting that the triggering condition occurs, the base station reports the subscription content to the first network device, such as including the base station ID, the metric data of the user, and the user location.

[0326] The subscription process of this example is equivalent to the first subscription process in the above embodiment, and at least includes the process of the first network device sending a first subscription request to at least one third base station and receiving the first information sent by at least one third base station.

[0327] Exemplarily, the code implementation of the above subscription request content can be referred to as follows:

[0328]

[0329]

[0330] Step 4, the first network device determines to send the second information to the base station to be woken up according to the user's data (such as the first data) and the user's location information (such as the first location information), using the first relationship information (or neighbor wake-up relationship table).

[0331] Specifically, Figure 8 is the interaction process schematic of the network energy-saving wake-up method of the embodiment of the present invention Figure 1 ; as Figure 8 shown, the method includes:

[0332] Step 701: Generate the second information.

[0333] Here, the first network device screens the user data reported by all neighboring cells of the cell to be woken up, and specifically determines whether the user's location information is within the trigger area; if it is within the trigger area, it can be determined as a woken-up user. Calculate the conversion factor according to the data of the woken-up user, and compare the first value obtained by adding up the conversion factors of all users with the second threshold of the base station to decide whether to wake up the base station. In this example, the first value is greater than or equal to the second threshold, so the second information for energy-saving wake-up is generated.

[0334] Step 702: The first network device sends the second information to the base station to be woken up.

[0335] Step 703: The base station to be woken up executes the energy-saving wake-up strategy based on the second information and feeds back the successful execution to the first network device.

[0336] Specifically, the above first network device can be implemented by Near-RT RIC / xApp or None-RTRIC / rApp in the O-RAN architecture; it can also be implemented by the control base station in the way of OMC or base station cluster.

[0337] Figure 9 is the interaction process schematic of the network energy-saving wake-up method of the embodiment of the present invention Figure 2; In this example, based on the O-RAN architecture, the intelligent control platform (Near-RT RIC / xAPP) realizes collaborative network energy-saving wake-up. The intelligent control platform (Near-RT RIC / xAPP) may include a Near-RT RIC Platform and an xAPP (uplink interference prediction module).

[0338] In this example, the E2 interface connecting the enhanced Near-RT RIC and the base station is implemented to enable the Near-RT RIC to subscribe to and receive the energy-saving status of the base station; based on the Near-RT RIC / xAPP, user KPIs and user location information for triggering the wake-up of the base station are subscribed, and an energy-saving policy is generated; the enhanced E2 interface is implemented to enable the Near-RT RIC to issue the energy-saving policy. As Figure 9 shown, the method includes:

[0339] Step 801: The intelligent control platform (Near-RT RIC / xAPP) subscribes to the configuration information of the base station and its neighboring cells, as well as the location information of the base station and its neighboring cells, and constructs a neighboring cell wake-up relationship table for the base station according to the configuration information of the base station and its neighboring cells and the location information of the base station and its neighboring cells.

[0340] This step may include: The xAPP (uplink interference prediction module) sends an E2 subscription request (E2 SUBSCRIPTION(Request)) to the Near-RT RIC Platform, requesting to subscribe to the configuration information of the base station and its neighboring cells, as well as the location information of the base station and its neighboring cells; this subscription request may be sent through the RIC application programming interface (API, Application Programming Interface). The Near-RT RIC Platform initiates a subscription process (SUBSCRIPTION PROCEDURE) to the base station through the E2 interface; the Near-RT RIC Platform sends a message of E2 subscription success (E2 SUBSCRIPTION(Success)) to the xAPP (uplink interference prediction module) through the RIC API. The base station that receives the subscription request sends an indication report (Indication Report) to the Near-RT RIC Platform through the E2 interface, which includes the subscription content; the Near-RT RIC Platform sends an E2 indication (E2 Indication) to the xAPP (uplink interference prediction module) through the RIC API; the xAPP (uplink interference prediction module) designs index data and thresholds, wake-up factor conversion relationships, and a second threshold, and constructs a neighboring cell wake-up relationship table.

[0341] Step 802: The intelligent control platform (Near-RT RIC / xAPP) subscribes to the status information reported by the base station through the E2 interface.

[0342] This step may include: the xAPP (uplink interference prediction module) sends an E2 subscription request (E2 SUBSCRIPTION (Request)) to the Near-RT RIC Platform, requesting to subscribe to the status information of the base station, and this subscription request can be sent through the RIC API. The Near-RT RIC Platform initiates a subscription process operation (SUBSCRIPTION PROCEDURE Action) to the base station through the E2 interface; the subscription request includes the cell ID or base station ID, and the status information of the cell or base station; the triggering condition can be initialization or status change. The Near-RT RIC Platform sends a message of E2 subscription success (E2 SUBSCRIPTION (Success)) to the xAPP (uplink interference prediction module) through the RIC API. The base station that receives the subscription request sends an indication report (Indication Report) to the Near-RT RIC Platform through the E2 interface, which includes the subscribed content, such as the status information of the cell or base station; the Near-RT RIC Platform sends an E2 indication (E2 Indication) to the xAPP (uplink interference prediction module) through the RIC API, which may include the status information of the cell or base station.

[0343] Step 803: The intelligent control platform (Near-RT RIC / xAPP) subscribes to the user data and user location information that trigger energy-saving wake-up from neighboring base stations.

[0344] This step may include: the xAPP (uplink interference prediction module) sends an E2 subscription request (E2 SUBSCRIPTION (Request)) to the Near-RT RIC Platform, requesting neighbor cell user data and user location information. This subscription request can be sent through the RIC API. The Near-RT RIC Platform initiates a subscription process operation (SUBSCRIPTION PROCEDURE Action) to the neighbor cell base station through the E2 interface; the subscription request includes user data (or KPIs, metric data, etc.) and the location information of the user; the trigger condition can be that the user data for energy-saving wake-up is worse than the threshold. The Near-RT RIC Platform sends a message of E2 subscription success (E2 SUBSCRIPTION (Success)) to the xAPP (uplink interference prediction module) through the RIC API. The neighbor cell base station that receives the subscription request sends an indication report (Indication Report) to the Near-RT RIC Platform through the E2 interface, which includes the subscription content. The Near-RT RIC Platform sends an E2 indication (E2 Indication) to the xAPP (uplink interference prediction module) through the RIC API, which may include the subscription content.

[0345] Step 804: The intelligent control platform (Near-RT RIC / xAPP) issues a base station wake-up policy to the base station to be woken up through the E2 interface according to the neighbor cell relationship, base station status information, neighbor cell user data, and user location information.

[0346] This step may include: the xAPP (uplink interference prediction module) generates a base station wake-up policy and sends an E2 control message to the Near-RT RIC Platform through the RIC API. The E2 control message includes the base station wake-up policy. The Near-RT RIC Platform sends the base station wake-up policy to the base station to be woken up through the E2 interface. After the base station to be woken up is woken up, it sends a control acknowledgement (CONTROL ACKNOWLEDGE) message to the Near-RT RIC Platform through the E2 interface.

[0347] It should be noted that the specific implementation processes of the above steps 801 to 804 can be referred to those described in the foregoing embodiments. This embodiment mainly describes the implementation architecture and interfaces.

[0348] In other alternative embodiments, when the first network device is the control base station in the base station cluster, the specific implementation can be carried out by referring to the implementation method through the intelligent control platform. The difference is that the control base station interacts with the base station to be woken up and the neighbor cell base station through the X2 interface.
