The capacity base station provides a communication service for at least one terminal device based on an operation mode, an energy-saving transition mode and an energy-saving mode. When in the operation mode, the capacity base station determines whether to switch the capacity base station to the energy-saving transition mode based on predicted load information corresponding to the capacity base station. When in the energy-saving transition mode, the capacity base station transfers the communication service corresponding to the at least one terminal device to at least one neighboring base station. In response to completion of handover of the communication service of the at least one terminal device, the capacity base station switches to the energy saving mode, where the capacity base station switched to the energy saving mode suspends providing the communication service.

Description

Technical Field

[0001] This disclosure relates to a capacity base station and its management method, and more particularly to an energy-saving capacity base station and its management method. Background Technology

[0002] With the development of communication technology, mobile communication technology has been applied to many services, and as a result, telecommunications operators have supported more frequency bands, larger bandwidths, more antennas, and denser networks to meet market demands.

[0003] Research indicates that the energy consumed by mobile communication networks is primarily used to maintain the wireless network, with base stations accounting for the largest share of that energy consumption. Therefore, base station energy conservation has always been a key research focus in the field of mobile communication network energy conservation.

[0004] In the standards defined by 3GPP, capacity booster cells (CBCs) can hand over connected user equipment (UEs) to other base stations and switch to power-saving mode to reduce energy consumption when the load decreases. On the other hand, coverage cells (CCs) are used to provide a wider signal coverage area. When the load on a coverage cell becomes high, it can transfer the communication services of some user equipment to capacity booster cells within the coverage area to achieve the purpose of load distribution.

[0005] However, the existing energy-saving mode switching mechanism has the following problems: (1) When the capacity base station transfers its own traffic to other base stations and switches to energy-saving mode, causing other base stations to be overloaded, the capacity base station still needs to be activated again to share the overloaded traffic, causing the capacity base station to switch on and off repeatedly; (2) When two adjacent capacity base stations transfer user equipment to each other at the same time to prepare to enter energy-saving mode, neither of them can clear the load and switch to energy-saving mode.

[0006] In view of this, how to avoid the aforementioned conflicting situations and enable capacity base stations to switch to energy-saving mode is an urgent goal that the industry needs to strive for. Summary of the Invention

[0051] To make the description of this disclosure more detailed and complete, reference can be made to the accompanying drawings and the various embodiments described below, in which the same numbers represent the same or similar elements.

[0052] First, please refer to Figure 1 This diagram illustrates the coverage base station (CC) and capacity base station (CBC) in some embodiments disclosed herein. As shown in the dashed line, the coverage base station (CC) has a relatively large signal coverage area; conversely, as shown in the dashed line, the capacity base station (CBC) is used to share the signal load for a portion of the area. The coverage base station (CC) and capacity base station (CBC) provide communication services to terminal devices (i.e., user equipment) within their signal coverage area.

[0053] When the number of user equipment in the coverage area of ​​a capacity base station (CBC) decreases and it is ready to switch to energy-saving mode, the capacity base station (CBC) can transfer the communication services of the user equipment it serves to a nearby coverage base station (CC) or capacity base station (CBC), such as coverage base stations (CC) or capacity base stations (CBC) with overlapping signal coverage areas.

[0054] Please refer to Figure 2 This is a schematic diagram of a capacity base station (CBC) according to one embodiment of the present disclosure. The capacity base station (CBC) includes a processor 12 and a communication interface 14, wherein the processor 12 is electrically connected to the communication interface 14.

[0055] In some embodiments, processor 12 may include a central processing unit (CPU), a graphics processing unit (GPU), a multiprocessor, a distributed processing system, an application-specific integrated circuit (ASIC), and / or a suitable computing unit.

[0056] Communication interface 14 provides a communication connection to a coverage base station (CC), such as a capacity base station (CBC) located within the signal coverage area of ​​the coverage base station CC. In some embodiments, communication interface 14 is also used to provide a communication connection to other nearby capacity base stations (CBCs). Furthermore, communication interface 14 is also used to provide a communication connection to one or more terminal devices (e.g., user equipment) to provide communication services.

[0057] In some embodiments, the communication interface 14 communicates with the coverage base station CC, the capacity base station CBC, and the terminal device based on a variety of different communication protocols, for example, through different frequency bands or wired or wireless means.

[0058] Please refer to Figure 3 , Figure 3 This is a schematic diagram of capacity base station mode switching in this embodiment. When the load of the capacity base station CBC decreases to a certain level and needs to switch from active mode (ACT) to energy saving mode (ES), the capacity base station CBC provides communication services to at least one terminal device through communication interface 14 based on active mode (ACT), energy saving transition mode (EST), and energy saving mode (ES).

[0059] Conversely, when load demand increases and the capacity base station CBC needs to switch from energy-saving mode ES to operating mode ACT, the capacity base station CBC provides communication services to at least one terminal device through communication interface 14 based on energy-saving mode ES, operating transition mode AT and operating mode ACT.

[0060] For details regarding mode switching, please refer to Figure 3 As shown in the figure, the capacity base station (CBC) disclosed in this invention will first switch to the energy-saving transition mode (EST) before switching from the operating mode (ACT) to the energy-saving mode (ES). Furthermore, the capacity base station (CBC) will only switch to the energy-saving mode (ES) after confirming that the serviced terminal equipment has been successfully handed over.

[0061] Specifically, in response to the capacity base station CBC being switched to operating mode ACT, the processor 12 performs the following operations: based on the predicted load information of the corresponding capacity base station CBC, determines whether to switch the capacity base station CBC to energy-saving transition mode EST. In response to the capacity base station CBC being switched to energy-saving transition mode EST, the processor 12 performs the following operations: transfers the communication service corresponding to at least one terminal device to at least one neighboring base station, wherein the at least one neighboring base station includes a coverage base station CC or a neighboring capacity base station of the corresponding capacity base station CBC; and in response to the completion of the transfer of the communication service of the at least one terminal device, switches the capacity base station CBC to energy-saving mode ES, wherein the capacity base station CBC switched to energy-saving mode ES suspends the provision of communication service.

[0062] For example, when a capacity base station (CBC) is in operating mode (ACT), it provides communication services to terminal devices within its signal range while predicting future load traffic. When it determines that the future predicted traffic reaches a specific criterion (e.g., traffic is below a threshold), the capacity base station (CBC) switches to power-saving transition mode (EST).

[0063] After switching to the energy-saving transition mode EST, the capacity base station CBC transfers the communication services of the user equipment it serves to the adjacent coverage base station CC and / or capacity base station CBC (i.e., neighboring base stations). Then, after transferring the communication services of all connected terminal equipment, it switches to the energy-saving mode ES.

[0064] In contrast, the capacity base station (CBC) proposed in this disclosure will first switch to a transitional operating mode (AT) before switching from energy-saving mode (ES) to operating mode (ACT). Furthermore, the capacity base station (CBC) will only switch to operating mode (ACT) after confirming the load of the terminal equipment that needs to be taken over.

[0065] Specifically, in response to the capacity base station CBC being switched to power-saving mode ES, the processor 12 performs the following operations: suspends the provision of communication services; and determines, based on the predicted load information of the corresponding coverage base station CC, whether to switch the capacity base station CBC to operating transition mode AT. In response to the capacity base station CBC being switched to operating transition mode AT, the processor 12 performs the following operations: transmits a handover invitation to the coverage base station CC; receives a handover request corresponding to the handover invitation from the coverage base station CC, wherein the handover request corresponds to at least one terminal device; and, based on the handover request, determines whether to switch the capacity base station CBC to operating mode ACT to provide communication services to at least one terminal device.

[0066] For example, when the capacity base station (CBC) is in power-saving mode (ES), it suspends communication services and predicts the future load traffic of the coverage base station (CC) at a future time (e.g., the capacity base station CBC within the signal range of the coverage base station CC predicts the future traffic of the coverage base station CC). When it is determined that the future predicted traffic reaches a certain standard (e.g., the traffic exceeds a threshold), the capacity base station CBC switches to the operation transition mode (AT).

[0067] After switching to the Transitional Operating Mode (AT), the Capacity Base Station (CBC) sends a handover invitation to the Coverage Base Station (CC) to confirm how many terminal devices' communication services can be transferred to the Capacity Base Station (CBC). Correspondingly, the Coverage Base Station (CC) receives the handover invitation and sends a handover request. Upon receiving the handover request, the Capacity Base Station (CBC) can obtain the number of terminal devices and / or load traffic that can be transferred from the Coverage Base Station (CC), and determine whether to switch to the Transitional Operating Mode (ACT) to share the load of the Coverage Base Station (CC). Finally, if the Capacity Base Station (CBC) switches to the Transitional Operating Mode (ACT), it takes over the communication services of the transferred terminal devices from the Coverage Base Station (CC).

[0068] Please refer to further details. Figure 4A This is a schematic diagram illustrating the operation of the capacity base station (CBC) switching from operating mode ACT to energy-saving mode ES in some embodiments of this disclosure. Additionally, please refer to... Figure 4B This corresponds to some embodiments disclosed herein. Figure 4A A schematic diagram illustrating the operation of a nearby base station.

[0069] First, during OP101 operation, the capacity base station (CBC) determines whether the predicted future load is below a threshold.

[0070] In some embodiments, when the Capacity Base Station (CBC) switches to Operation Mode ACT, a machine learning model is used to calculate future predicted traffic based on past and current load data (i.e., historical load records). Load data includes information such as allocated and used bandwidth, Physical Resource Blocks (PRBs), number of connected devices, uplink traffic, and downlink traffic.

[0071] Specifically, the operation of determining whether to switch the capacity base station (CBC) to the energy-saving transition mode (EST) further includes: calculating the predicted load information of the capacity base station (CBC) based on the historical load records of the capacity base station (CBC); and determining to switch the capacity base station (CBC) to the energy-saving transition mode (EST) in response to the predicted load information being lower than a first load threshold.

[0072] It should be noted that the machine learning models used to calculate predicted traffic can be based on model architectures such as Long Short-Term Memory (LSTM), Transformer, Gated Recurrent Unit (GRU), and can be trained and / or fine-tuned using past load data; however, this disclosure is not limited to this.

[0073] It should be noted that the first load threshold can be calculated based on the historical load records of the capacity base station (CBC). In some embodiments, the capacity base station (CBC) calculates the average load traffic as the first load threshold based on multiple load traffic volumes over a past period.

[0074] In some embodiments, the machine learning model calculates the predicted traffic over a future period, and the capacity base station (CBC) determines whether the predicted traffic is below a first load threshold to decide whether to switch modes.

[0075] As mentioned above, if the predicted load is not lower than the first load threshold, the capacity base station CBC maintains the operation mode ACT and continues to calculate the predicted load; conversely, if the predicted load is lower than the load threshold, the capacity base station CBC executes operation OP103 and switches to the energy-saving transition mode EST.

[0076] In some embodiments, after determining that the predicted load is lower than the first load threshold, the capacity base station (CBC) also confirms the current and future load information of neighboring base stations to determine whether to switch to the energy-saving transition mode (EST).

[0077] Specifically, in response to the determination to switch the capacity base station (CBC) to the energy-saving transition mode (EST), the processor 12 performs the following operations: obtains at least one neighboring load information from at least one neighboring base station; and, based on the at least one neighboring load information, decides whether to cancel the switch to the energy-saving transition mode (EST).

[0078] For example, when the predicted load is below a first load threshold, the capacity base station (CBC) sends a resource status request to neighboring base stations. Upon receiving this request, the neighboring base stations reply with a resource status response, which includes their current and future load information. If the future load traffic of a neighboring base station is too high, the capacity base station (CBC) may need to share the traffic, thus canceling the switch to the energy-saving transition mode (EST).

[0079] In some embodiments, when switching to the Energy Saving Transition Mode (EST), the Capacity Base Station (CBC) further broadcasts a signal to surrounding terminal devices to reject connections and transmits a signal to surrounding base stations to refuse handover of communication services to the terminal devices. Furthermore, if a handover request is received from a neighboring base station at this time, the Capacity Base Station (CBC) sends back a cancellation handover signal to refuse handover. On the other hand, for handover requests that have been previously confirmed but for which the handover process has not yet been completed, the Capacity Base Station (CBC) transmits a cancellation handover signal to cancel the handover operation.

[0080] Specifically, in response to the determination to switch the capacity base station CBC to the energy-saving transition mode EST, the processor 12 performs the following operations: broadcasts a first prohibition signal to at least one nearby terminal device to suspend the provision of communication services to at least one nearby terminal device; transmits a second prohibition signal to the nearby base station to reject the handover request of the corresponding nearby base station; in response to receiving the handover request from the nearby base station, transmits a cancellation handover signal back to the nearby base station; and after broadcasting the first prohibition signal and transmitting the second prohibition signal, switches the capacity base station CBC to the energy-saving transition mode EST.

[0081] For example, the capacity base station (CBC) broadcasts a cell barred signal via the Master Information Block (MIB) to reject connection requests from terminal devices. The capacity base station (CBC) also notifies neighboring base stations via the Xn interface that it is preparing to enter energy-saving transition mode (EST) to avoid handover requests from neighboring base stations.

[0082] For handover requests that have responded with a handover request acknowledgement (HO REQ ACK) but have not yet completed the handover procedure, the capacity base station (CBC) sends a handover cancel request (HO cancel REQ) to the corresponding neighboring base station to suspend the handover. Subsequently, if the neighboring base station refuses to cancel the handover (e.g., by receiving a rejection message from a neighboring base station), the capacity base station (CBC) will still switch to the energy-saving transition mode (EST) after completing the handover, and then transfer the communication services of the terminal equipment to other base stations in subsequent operations.

[0083] After switching to Energy Saving Transition Mode (EST), the Capacity Base Station (CBC) performs Operation OP105, transmitting an Energy Saving Handover Request (ES HO REQ) to neighboring base stations to confirm whether the communication services of the terminal devices can be handed over. The handover request includes the number of terminal devices and traffic that the Capacity Base Station (CBC) expects to hand over.

[0084] In some embodiments, the Capacity Base Station (CBC) uses a machine learning model to predict the future movement trajectory of each terminal device based on its past and present locations. Further, based on the terminal device's future movement trajectory, it is assigned to a nearby base station, such as one located closer in the future.

[0085] Specifically, the operation of transferring the communication service of at least one terminal device further includes: allocating at least one terminal device to at least one neighboring base station based on at least one trajectory prediction corresponding to each of the at least one terminal device to generate an allocation result; transmitting at least one transfer request to at least one neighboring base station based on the allocation result; receiving a transfer response corresponding to the transfer request from at least one neighboring base station; and transferring the communication service of at least one of the at least one terminal device based on the transfer response.

[0086] Similarly, machine learning models used to predict the movement trajectory of terminal devices are generated based on past location records of the terminal devices, trained and / or fine-tuned.

[0087] In some embodiments, after the terminal equipment is allocated to each neighboring base station, the handover request transmitted by the capacity base station (CBC) may also include the number of terminal equipment to be handed over to a specific neighboring base station, traffic, and predicted trajectory.

[0088] Please return Figure 4B After the capacity base station (CBC) transmits the handover request, during operation OP201, the neighboring base station receives the handover request.

[0089] Furthermore, during OP203 operation, neighboring base stations assess their own load and determine the number of terminal devices and / or traffic that can be taken over based on handover requests.

[0090] Next, during OP205 operation, the neighboring base station transmits a handover response to the capacity base station CBC based on the assessment results.

[0091] For example, suppose a handover request transmitted by a capacity base station (CBC) indicates that the communication services of a total of 7 terminal devices need to be handed over, of which 3 are assigned to neighboring base station A, and the handover request also records the predicted trajectory, service requirements (e.g., bandwidth, QoS), required resources and / or traffic of each terminal device.

[0092] At this point, if the load of a nearby base station is no longer able to take over any terminal device, its energy saving handover request will fail (ES HO Failure).

[0093] In another scenario, if a neighboring base station is able to take over the terminal equipment, it sends back an energy saving handover request acknowledgement (ES HO REQ ACK), which includes the number of terminal equipment that the neighboring base station is able to take over, traffic, reserved spectrum resources and / or reserved computing resources.

[0094] It should be noted that if the number of terminal devices and / or traffic that a neighboring base station can take over exceeds the allocated number and / or traffic (e.g., 5 devices), the neighboring base station can also reserve spectrum resources and computing resources for 5 devices and send the data back to the capacity base station (CBC).

[0095] Accordingly, the capacity base station (CBC) and neighboring base stations complete the preparatory work for the handover. Therefore, during operation OP107, the capacity base station (CBC) hands over the communication services of the terminal equipment; simultaneously, during operation OP207, the neighboring base station takes over the terminal equipment.

[0096] Next, during operation OP109, the capacity base station (CBC) confirms whether communication services for all connected terminal devices have been handed over. If communication services for all terminal devices cannot be handed over due to insufficient load on neighboring base stations, handover failure, or other reasons, the capacity base station (CBC) returns to operation OP105 and attempts the handover operation again.

[0097] In some embodiments, to avoid repeatedly executing multiple handover requests while neighboring base stations cannot provide load in a short period of time, the capacity base station (CBC) sets a timer and waits for a period of time (e.g., 10 seconds) before transmitting the handover request again.

[0098] Next, once the communication services of all terminal equipment have been handed over, the capacity base station (CBC) switches to energy-saving mode (ES) during operation OP111.

[0099] In some embodiments, after completing the handover of communication services for all terminal devices, the capacity base station (CBC) notifies neighboring base stations that it will enter power-saving mode (ES). Correspondingly, in operation OP209, the neighboring base station removes the capacity base station (CBC) from the neighboring base station list upon receiving the notification.

[0100] Specifically, in response to the capacity base station CBC being switched to the energy-saving transition mode EST, the processor 12 further performs the following operations: in response to the completion of the handover of communication services of at least one terminal device, it transmits a notification signal to at least one neighboring base station so that at least one neighboring base station removes the capacity base station CBC from the neighboring base station list; and after completing the transmission of the notification signal, it switches the capacity base station CBC to the energy-saving mode ES.

[0101] For example, the capacity base station (CBC) notifies neighboring base stations via the Xn interface that it is preparing to enter power-saving mode (ES). Upon receiving this notification, the neighboring base stations update their Automatic Neighbor Relation list (ANR list).

[0102] In some embodiments, to avoid the inability to smoothly hand over communication services to all terminal devices and remain in the energy-saving transition mode EST, which would prevent the capacity base station CBC from switching to the energy-saving mode ES and from serving new terminal devices, the capacity base station CBC also sets specific conditions to avoid getting stuck in an infinite loop.

[0103] Specifically, after the capacity base station CBC is switched to the energy-saving transition mode EST, in response to the fulfillment of the tripping condition, the processor 12 switches the capacity base station CBC to the operating mode ACT.

[0104] Specifically, the tripping conditions include the duration after the capacity base station (CBC) is switched to the energy-saving transition mode (EST) exceeding a duration threshold and the capacity base station (CBC) not being switched to the energy-saving mode (ES).

[0105] For example, if the capacity base station CBC is switched to the energy-saving transition mode EST for more than 10 seconds, and cannot switch back to the energy-saving mode ES due to reasons such as the inability to transfer the communication services of all terminal devices, then the processor 12 will switch the capacity base station CBC back to the operating mode ACT.

[0106] Specifically, the skip condition includes the number of times the capacity base station (CBC) transmits a handover request to a neighboring base station exceeding a certain threshold.

[0107] For example, if the capacity base station CBC attempts to transmit a handover request to a neighboring base station more than 5 times, and is unable to hand over all communication services and switch to power saving mode ES due to reasons such as the neighboring base station being overloaded, then the processor 12 will switch the capacity base station CBC back to operating mode ACT.

[0108] It should be noted that the tripping conditions described in this disclosure are for illustrative purposes only, and this disclosure is not limited to them. In fact, the capacity base station (CBC) can set other tripping conditions as needed.

[0109] Furthermore, in some embodiments, if the capacity base station CBC is switched back to the operating mode ACT due to the triggering of the tripping condition, it may indicate that the capacity base station CBC is temporarily unable to enter the energy-saving mode ES. Therefore, after switching back to the operating mode ACT, the capacity base station CBC sets a timer to prevent it from being switched back to the energy-saving transition mode EST again in a short period of time.

[0110] Specifically, in response to the tripping condition being met, after the capacity base station CBC is switched to the operating mode ACT, the processor 12 does not switch the capacity base station CBC to the energy-saving transition mode EST within a specific time interval.

[0111] For clarity, please refer to [link / reference]. Figure 4C This is a schematic diagram illustrating the operation of a capacity base station (CBC) switching from operating mode ACT to power-saving mode ES in another embodiment of this disclosure, wherein OP101, OP103, OP105, OP107, OP109, and OP111 are operating. Figure 4A The corresponding operations are similar, so the similarities will not be repeated.

[0112] In operation OP109, if the capacity base station (CBC) is unable to hand over communication services to all terminal devices, the capacity base station (CBC) executes operation OP110 to determine whether the tripping conditions are met. If the tripping conditions are met, the capacity base station (CBC) executes operation OP112; if the tripping conditions are not met, the capacity base station (CBC) returns to operation OP105.

[0113] In other words, when the capacity base station (CBC) attempts to transmit handover requests too many times and / or the duration of entering the energy-saving transition mode (EST) is too long, the capacity base station (CBC) will execute operation OP112 and switch to operation mode (ACT).

[0114] Furthermore, after switching to the operating mode ACT, the capacity base station CBC executes operation OP113. After a certain duration, the capacity base station CBC returns to operation OP101 to determine whether to switch to the energy-saving transition mode EST.

[0115] According to the above embodiments, the capacity base station (CBC) proposed in this disclosure ensures the smooth handover of communication services for all terminal devices by first switching to the energy-saving transition mode (EST) and coordinating load and handover of communication services with neighboring base stations, thus avoiding service requests from terminal devices during this phase. Simultaneously, before switching to energy-saving mode (ES), the capacity base station (CBC) ensures that neighboring base stations have sufficient load capacity to accommodate terminal devices. Furthermore, after switching to energy-saving mode (ES), the capacity base station (CBC) prevents neighboring base stations from becoming overloaded in a short period and needing to switch back to operating mode (ACT). Further, after switching to energy-saving transition mode (EST), the capacity base station (CBC) can also set tripping conditions to prevent the inability to switch to energy-saving mode (ES) and continued operation in energy-saving transition mode (EST).

[0116] On the other hand, please refer to further Figure 5A This is a schematic diagram illustrating the operation of the capacity base station (CBC) switching from power-saving mode (ES) to operating mode (ACT) in some embodiments of this disclosure. Additionally, please refer to... Figure 5B This corresponds to some embodiments disclosed herein. Figure 5A A schematic diagram illustrating the operation of a nearby base station.

[0117] First, during OP301 operation, the capacity base station (CBC) determines whether the predicted future load of the coverage base station (CC) is higher than a threshold.

[0118] Similarly, in some embodiments, when the capacity base station (CBC) switches to power-saving mode (ES), it continuously receives load data from the coverage base station (CC) and calculates future predicted traffic using a machine learning model based on past and current coverage base station CC load data (i.e., historical load records). The load data includes information such as allocated and used bandwidth, physical resource blocks, number of connected devices, uplink traffic, and downlink traffic.

[0119] Specifically, the operation of determining whether to switch the capacity base station CBC to the operation transition mode AT further includes: calculating the predicted load information of the coverage base station CC based on the historical load records of the coverage base station CC; and determining to switch the capacity base station CBC to the operation transition mode AT in response to the predicted load information being higher than a second load threshold.

[0120] It should be noted that the machine learning model used to calculate predicted traffic can be based on model architectures such as LSTM, Transformer, GRU, etc., and can be trained and / or fine-tuned using past load data; however, this disclosure is not limited to this.

[0121] It should be noted that the second load threshold can be calculated based on the historical load records of the coverage base station CC. In some embodiments, the capacity base station CBC calculates the average load traffic as the second load threshold based on multiple load traffic events of the coverage base station CC over a past period.

[0122] In some embodiments, the machine learning model calculates the predicted traffic of the coverage base station (CC) over a future period, and the capacity base station (CBC) determines whether the predicted traffic is higher than a second load threshold to decide whether to switch modes.

[0123] If the predicted load is not higher than the second load threshold, the capacity base station CBC maintains the power saving mode ES and continues to calculate the predicted load; conversely, if the predicted load is higher than the load threshold, the capacity base station CBC executes operation OP303 and switches to the operation transition mode AT.

[0124] In some cases, a portion of the load handled by the coverage base station CC may be outside the signal coverage and / or service range of the capacity base station CBC. Accordingly, in some embodiments, the capacity base station CBC also determines from the load data provided by the coverage base station CC how much traffic is a load that the capacity base station CBC can take over in the future, and determines whether to switch to the transitional operating mode AT based on the manageable load. For example, the capacity base station CBC can determine the amount of manageable load by the location of the terminal equipment.

[0125] Specifically, the operation of determining whether to switch the capacity base station CBC to the operation transition mode AT further includes: calculating the predicted handover load of the corresponding capacity base station CBC in the historical load record based on the historical load record of the coverage base station CC; and determining to switch the capacity base station CBC to the operation transition mode AT only when the predicted handover load is higher than a second load threshold.

[0126] In some embodiments, the capacity base station (CBC) can use a machine learning model to calculate its own predicted traffic based on past load data (e.g., the machine learning model used to calculate the predicted traffic of the capacity base station CBC in the foregoing embodiments).

[0127] In another embodiment, the capacity base station (CBC) can also determine which terminal devices are manageable loads based on their future trajectories. For example, this can be done using the machine learning model described in the preceding embodiments for predicting terminal device movement trajectories.

[0128] After switching to the transitional operating mode AT, in operation OP305, the capacity base station CBC transmits a handover invitation to the coverage base station CC.

[0129] For example, the capacity base station (CBC) transmits a resource status update signal to the coverage base station (CC). This resource status update signal includes an offload invite signal and the capacity base station's (CBC) available resource capacity. The capacity base station's (CBC) available resource capacity includes the amount of traffic it can accommodate, the available spectrum, the permissible power value, and / or the maximum number of devices it can accommodate.

[0130] Please return Figure 5B After the capacity base station CBC transmits the handover invitation, the coverage base station CC receives the handover invitation during operation OP401.

[0131] Furthermore, in operation OP403, the coverage base station CC calculates the load (e.g., the number of terminal devices and / or traffic that can be transferred to the capacity base station CBC) based on the handover invitation.

[0132] Next, during OP405 operation, the coverage base station CC transmits a handover request to the capacity base station CBC based on the handover load.

[0133] In some embodiments, the coverage base station CC calculates the load to be transferred to the capacity base station CBC based on the terminal devices within the signal coverage area of ​​the capacity base station CBC.

[0134] Specifically, the handover request is generated by the following operations: calculating the handover load of the corresponding capacity base station (CBC) based on at least one location information corresponding to at least one surrounding terminal device; and generating a handover request based on the handover load.

[0135] In some cases, the capacity base station (CBC) will still broadcast SSB and SIB1 signals even when it is in power-saving mode (ES). In this way, terminal devices around the capacity base station (CBC) can sense the presence of the capacity base station (CBC) and confirm their distance and / or relative position to the capacity base station (CBC).

[0136] Accordingly, the coverage base station (CC) can calculate how many terminal devices are within the signal coverage area of ​​the capacity base station (CBC) based on the distance and / or relative location reported by the terminal devices, and then calculate the handover load.

[0137] In other cases, the capacity base station (CBC) will not broadcast SSB and SIB1 signals when it is in power-saving mode (ES). As a result, terminal devices around the capacity base station (CBC) cannot determine their distance and / or relative position to the capacity base station (CBC).

[0138] Accordingly, the coverage base station CC uses a machine learning model to predict whether the future movement trajectory of the terminal device will enter the signal coverage area of ​​the capacity base station CBC based on the past and present location of the terminal device (e.g., the machine learning model used to predict the movement trajectory of the terminal device in the aforementioned embodiment), and then calculates the handover load.

[0139] Specifically, the handover request is generated by the following operations: calculating at least one predicted location of at least one surrounding terminal device based on at least one historical load record of at least one surrounding terminal device; and calculating the handover load of the corresponding capacity base station (CBC) based on at least one predicted location to generate the handover request.

[0140] After calculating the handover load, the coverage base station (CC) transmits a handover request, which includes the expected number of terminal devices to be handed over, traffic, predicted trajectory, and service requirements (e.g., bandwidth, QoS).

[0141] Correspondingly, after receiving the handover request, in order to determine whether switching to the operating mode ACT is cost-effective, the capacity base station CBC determines whether the handover load is higher than the third load threshold in operation OP307.

[0142] Specifically, the operation of determining whether to switch the capacity base station (CBC) to the operating mode (ACT) further includes: in response to the handover load in the handover request being higher than a third load threshold, determining to switch the capacity base station (CBC) to the operating mode (ACT).

[0143] If the handover load is not higher than the third load threshold, the capacity base station (CBC) determines that it does not need to switch to operating mode (ACT) and sends a cancellation handover signal back to the coverage base station (CC) to cancel the handover operation. Next, in operation OP309, the capacity base station (CBC) switches to power-saving mode (ES) and returns to operation OP301.

[0144] If the handover load exceeds the third load threshold, in operation OP311, the capacity base station CBC sends back a handover confirmation signal and switches to operation mode ACT. Correspondingly, in operation OP407, the coverage base station CC begins handing over communication services to the terminal equipment; simultaneously, in operation OP313, the capacity base station CBC takes over the terminal equipment.

[0145] It should be noted that, in some embodiments, the confirmation handover signal includes terminal equipment that the capacity base station (CBC) can take over, reserved spectrum resources, and / or reserved computing resources.

[0146] It should be noted that the third load threshold can be calculated based on the historical load records of the capacity base station (CBC). In some embodiments, similar to the first load threshold, the capacity base station (CBC) calculates the average load traffic as the third load threshold based on multiple load traffic events over a past period.

[0147] According to the above embodiments, the capacity base station (CBC) proposed in this disclosure ensures efficient operation by first switching to the transitional operating mode (AT) and confirming the terminal devices and loads to be handed over with the coverage base station (CC). Furthermore, the capacity base station (CBC) can timely distribute traffic by predicting and monitoring the load of the coverage base station (CC). Simultaneously, by determining whether individual terminal devices are within the signal coverage area of ​​the capacity base station (CBC), the handover load can be more accurately determined.

[0148] Please refer to Figure 6 This is a flowchart illustrating the switching from operating mode ACT to power-saving mode ES in a base station management method 500 according to another embodiment of this disclosure. The base station management method 500 includes steps S501 to S505. The base station management method 500 is used to provide communication services to at least one terminal device through a capacity base station CBC based on the operating mode ACT, the power-saving transition mode EST, and the power-saving mode ES. The base station management method 500 can be executed by a capacity base station (e.g., the capacity base station CBC in the first embodiment).

[0149] First, in step S501, in response to the capacity base station CBC being switched to the operating mode ACT, the capacity base station CBC determines whether to switch the capacity base station CBC to the energy-saving transition mode EST based on the predicted load information of the corresponding capacity base station CBC.

[0150] Next, in step S503, in response to the capacity base station CBC being switched to the energy-saving transition mode EST, the capacity base station CBC transfers the communication service of the corresponding terminal device to at least one neighboring base station, wherein the at least one neighboring base station includes at least one of the coverage base station CC and the neighboring capacity base station of the corresponding capacity base station CBC.

[0151] Finally, in step S505, in response to the completion of the handover of communication services for at least one terminal device, the capacity base station CBC switches to power saving mode ES, wherein the capacity base station CBC switched to power saving mode ES suspends the provision of communication services.

[0152] In some embodiments, step S501 further includes the capacity base station CBC calculating the predicted load information of the capacity base station CBC based on the historical load records of the capacity base station CBC; and in response to the predicted load information being lower than a first load threshold, the capacity base station CBC determining to switch the capacity base station CBC to the energy-saving transition mode EST.

[0153] In some embodiments, in response to determining to switch the capacity base station CBC to the energy-saving transition mode EST, the base station management method 500 further includes the capacity base station CBC broadcasting a first prohibition signal to at least one neighboring terminal device to suspend providing communication services to at least one neighboring terminal device; the capacity base station CBC transmitting a second prohibition signal to the neighboring base station to reject the handover request of the corresponding neighboring base station; in response to receiving the handover request from the neighboring base station, the capacity base station CBC transmitting a cancellation handover signal back to the neighboring base station; and after broadcasting the first prohibition signal and transmitting the second prohibition signal, the capacity base station CBC switches to the energy-saving transition mode EST.

[0154] In some embodiments, step S503 further includes the capacity base station (CBC) allocating at least one terminal device to at least one neighboring base station based on at least one trajectory prediction corresponding to each of the at least one terminal device to generate an allocation result; the capacity base station (CBC) transmitting at least one handover request to at least one neighboring base station based on the allocation result; the capacity base station (CBC) receiving a handover response corresponding to the handover request from at least one neighboring base station; and handing over the communication service of at least one of the at least one terminal device based on the handover response.

[0155] In some embodiments, in response to the capacity base station CBC being switched to the energy-saving transition mode EST, the base station management method 500 further includes, in response to the completion of the handover of communication services for at least one terminal device, the capacity base station CBC transmits a notification signal to at least one neighboring base station so that at least one neighboring base station removes the capacity base station CBC from the neighboring base station list; and after the capacity base station CBC completes transmitting the notification signal, it switches the capacity base station CBC to the energy-saving mode ES.

[0156] In some embodiments, in response to determining to switch the capacity base station CBC to the energy-saving transition mode EST, the base station management method 500 further includes the capacity base station CBC obtaining at least one neighboring load information from at least one neighboring base station; and the capacity base station CBC deciding whether to cancel the switch to the energy-saving transition mode EST based on the at least one neighboring load information.

[0157] In some embodiments, the base station management method 500 further includes switching the capacity base station CBC to the operating mode ACT in response to meeting the tripping condition after the capacity base station CBC is switched to the energy-saving transition mode EST.

[0158] In some embodiments, the tripping condition includes the duration after the capacity base station (CBC) is switched to the energy-saving transition mode (EST) exceeding a duration threshold and the capacity base station (CBC) not being switched to the energy-saving mode (ES).

[0159] In some embodiments, the tripping condition includes the number of times the capacity base station (CBC) transmits a handover request to a neighboring base station exceeding a certain threshold.

[0160] In some embodiments, the base station management method 500 further includes not switching the capacity base station CBC to the energy-saving transition mode EST for a specific time interval after the tripping condition is met and the capacity base station CBC is switched to the operating mode ACT.

[0161] According to the above embodiments, the base station management method 500 disclosed herein ensures that the capacity base station CBC smoothly hands over the communication services of all terminal devices by first switching the capacity base station CBC to the energy-saving transition mode EST and coordinating the load and handover of communication services of terminal devices with neighboring base stations, thus avoiding any terminal devices requesting services during this stage. Simultaneously, before switching to the energy-saving mode ES, the base station management method 500 ensures that neighboring base stations have sufficient load capacity to accommodate terminal devices. Furthermore, after switching to the energy-saving mode ES, the base station management method 500 avoids the need for neighboring base stations to switch back to the operating mode ACT due to short-term overload.

[0162] Please refer to Figure 7 This is a flowchart illustrating the switching from a power-saving mode ES to an operating mode ACT in another embodiment of the base station management method 600 disclosed herein. The base station management method 600 includes steps S601 to S609. The base station management method 600 is used to provide communication services to at least one terminal device through a capacity base station CBC based on the power-saving mode ES, the operating transition mode AT, and the operating mode ACT. The base station management method 600 can be executed by a capacity base station (e.g., the capacity base station CBC in the first embodiment).

[0163] First, in step S601, in response to the capacity base station CBC being switched to power-saving mode ES, communication services are suspended.

[0164] Next, in step S603, the capacity base station CBC determines whether to switch the capacity base station CBC to the operation transition mode AT based on the predicted load information of the corresponding coverage base station CC.

[0165] Next, in step S605, in response to the capacity base station CBC being switched to the operation transition mode AT, the capacity base station CBC transmits a handover invitation to the coverage base station CC.

[0166] Next, in step S607, the capacity base station CBC receives a handover request corresponding to the handover invitation from the coverage base station CC, wherein the handover request corresponds to at least one terminal device.

[0167] Finally, in step S609, the capacity base station CBC determines, based on the handover request, whether to switch the capacity base station CBC to operating mode ACT to provide communication services for at least one terminal device.

[0168] In some embodiments, step S603 further includes the capacity base station CBC calculating the predicted load information of the coverage base station CC based on the historical load records of the coverage base station CC; and in response to the predicted load information being higher than a second load threshold, the capacity base station CBC determining to switch the capacity base station CBC to the operation transition mode AT.

[0169] In some embodiments, a handover request is generated by the following steps: calculating the handover load of a corresponding capacity base station (CBC) based on at least one location information corresponding to at least one surrounding terminal device; and generating a handover request based on the handover load.

[0170] In some embodiments, the handover request is generated by the following steps: calculating at least one predicted location of at least one surrounding terminal device based on at least one historical load record of at least one surrounding terminal device; and calculating the handover load of the corresponding capacity base station (CBC) based on the at least one predicted location to generate the handover request.

[0171] In some embodiments, step S609 further includes responding to a handover load in a handover request that is higher than a third load threshold, and the capacity base station CBC determines to switch the capacity base station CBC to operating mode ACT.

[0172] In some embodiments, step S603 further includes the capacity base station CBC calculating the predicted handover load of the corresponding capacity base station CBC in the historical load record based on the historical load record of the coverage base station CC; and the capacity base station CBC determining to switch the capacity base station CBC to the operation transition mode AT in response to the predicted handover load being higher than a second load threshold.

[0173] According to the above embodiments, the base station management method 600 disclosed herein ensures efficient operation by first switching the capacity base station (CBC) to the operation transition mode (AT) and confirming the terminal equipment and load to be transferred with the coverage base station. Furthermore, the base station management method 600 can timely distribute traffic by predicting and monitoring the load of the coverage base station. Simultaneously, by determining whether individual terminal equipment is within the signal coverage area of ​​the capacity base station (CBC), the method can more accurately determine the load transfer.

[0174] Although several embodiments have been described in detail above as examples, the capacity base station and its management method proposed in this disclosure can also be implemented in other systems, hardware, software, storage media, or combinations thereof. Therefore, the scope of protection of this disclosure should not be limited to the specific implementations described in the embodiments of this disclosure, but should be determined by the appended claims.
