Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a base station wake-up method, a base station hibernation method, an apparatus, network equipment, and a medium. Background Technology

[0002] 5G's peak energy efficiency is far higher than 4G, but 5G services suffer from tidal effects and uneven load distribution, with base stations frequently idling during low-load periods, resulting in significant energy waste. To address these issues, the industry has proposed base station sleep technology. 5G base station power consumption can be divided into two main parts: AAU (Active Antenna Unit) and BBU (Building Baseband Unit). Under full load, AAU power consumption accounts for approximately 90% of the total power consumption, making it the primary component of base station power consumption. However, after the AAU enters sleep mode, it can only be woken up when the configured sleep period arrives. Therefore, the BBU and AAU cannot be woken up promptly when encountering sudden surges in service, thus affecting user experience. Summary of the Invention

[0072] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0073] Embodiments of the present invention, such as Figure 1 As shown, a base station wake-up method is provided, applied to a first BBU, the method comprising:

[0074] S101, receive the first wake-up signal sent by the second BBU through the transmission link between the first BBU and the second BBU. The first BBU belongs to the first base station and the second BBU belongs to the second base station.

[0075] It should be noted that, in this embodiment of the invention, the first base station is a capacity layer cell base station. Capacity layer cells are high-frequency network layer cells, characterized by high data transmission rates in the high-frequency band but small coverage radius and weak signal penetration, used to provide greater network capacity. The second base station is a coverage layer cell base station. Coverage layer cells are low-frequency network layer cells, characterized by low data transmission rates in the low-frequency band but large coverage radius and strong signal penetration, used to provide basic coverage. Therefore, the first BBU is a capacity layer BBU; the first AAU is a capacity layer AAU; and the second BBU is a coverage layer BBU.

[0076] In this embodiment of the invention, a transmission link between the first BBU and the second BBU enables the first BBU to receive a first wake-up signal sent by the second BBU while in sleep mode, thereby waking it up and waking up the first AAU. It is understood that in the event of a sudden surge in service, the second BBU can send a first wake-up signal to the first BBU via the transmission link, thus solving the problem in the prior art where BBUs and AAUs cannot be woken up in a timely manner when encountering sudden surges in service, ensuring a smooth user experience.

[0077] S102, according to the first wake-up signal, control the module in the first BBU that is in a sleep state at the target sleep level to enter the wake-up state.

[0078] In this embodiment of the invention, the module in the first BBU that is in a sleep state at the target sleep level is controlled to enter the wake-up state, that is, the first BBU is controlled to turn on the power supply to the module in the sleep state at the target sleep level.

[0079] S103, send a second wake-up signal to the first active antenna unit (AAU). The second wake-up signal is used to instruct the module in the first AAU that is in a sleep state at the target sleep level to enter a wake-up state. The first AAU belongs to the first base station.

[0080] In this embodiment of the invention, after the first BBU enters the wake-up state upon receiving the first wake-up signal from the second BBU, it sends a second wake-up signal to the first AAU (i.e., S102 and S103 are in sequence, with S102 preceding S103). After receiving the second wake-up signal, the first AAU turns on the power supply to the module in the sleep state of the target sleep level, thereby achieving the effect of serial wake-up.

[0081] It should be noted that after receiving the first wake-up signal from the second BBU, the first BBU can send a second wake-up signal to the first AAU while simultaneously controlling the module in the first BBU that is in the sleep state at the target sleep level to enter the wake-up state (i.e., S102 and S103 have no order and are performed simultaneously). Both the first BBU and the first AAU turn on the power supply to the module in the sleep state at the target sleep level, thereby achieving the effect of parallel wake-up and shortening the wake-up time.

[0082] Of course, after the first BBU receives the first wake-up signal from the second BBU, it can simultaneously control the modules in the first BBU that are in a sleep state at the target sleep level to enter the wake-up state, and also control the modules in the first AAU that are in a sleep state at the target sleep level to enter the wake-up state (i.e., S103 is omitted, and S102 is replaced with: according to the first wake-up signal, control the modules in the first BBU and the first AAU that are in a sleep state at the target sleep level to enter the wake-up state). In other words, both the first BBU and the first AAU can enter the wake-up state through the first wake-up signal from the second BBU, without the first BBU sending a second wake-up signal to the first AAU, thus achieving the effect of parallel wake-up and shortening the wake-up time.

[0083] In one embodiment, the transmission link may optionally include one of the following:

[0084] The optical module of the second BBU is connected to the optical module of the first BBU;

[0085] The second BBU and the first BBU are mounted on the back panel of the same chassis.

[0086] In this embodiment of the invention, by establishing the aforementioned transmission link between the first BBU and the second BBU, the first BBU and the second BBU can communicate. Of course, other signaling can also be transmitted between the first BBU and the second BBU, which will not be elaborated here.

[0087] It should be noted that the optical module of the second BBU is connected to the optical module of the first BBU via optical fiber, although other cables can also be used for the connection.

[0088] The second BBU and the first BBU are located in the same chassis, and they can transmit signals through the backplane in the chassis.

[0089] In one implementation, optionally, the first wake-up signal is sent by the second BBU to the first BBU when the second BBU determines that the first base station needs to enter a wake-up state based on the historical camping information of the currently accessed users of the second base station.

[0090] It should be noted that when the first base station is in a dormant state, the second BBU determines whether the first base station needs to exit the dormant state, i.e., whether the first base station needs to enter the wake-up state, based on the historical login information of the users currently connected to the second base station.

[0091] Specifically, the second BBU obtains the number of users who were previously registered with the first base station among the current users of the second base station based on the historical registration information reported by all current users of the second base station. When the number of users is higher than the fifth threshold, it determines that the first base station needs to enter the wake-up state and sends the first wake-up signal to the first BBU.

[0092] In one embodiment, optionally, before receiving the first wake-up signal sent by the second BBU via the transmission link between the second BBU and S101, the method further includes:

[0093] Based on the network load, determine whether the first base station needs to enter a sleep state.

[0094] If it is determined that the first base station needs to enter a sleep state, the online users of the first base station are migrated to the second base station, and a sleep signal is sent to the first AAU. The sleep signal is used to instruct the first AAU to enter a sleep state of the target sleep level.

[0095] Control at least one module in the first BBU corresponding to the target hibernation level to enter hibernation state.

[0096] In one embodiment, optionally, the above method further includes:

[0097] Based on the network load and the threshold values ​​corresponding to different hibernation levels, the target hibernation level is determined. The target hibernation level is one of the shallow hibernation level, deep hibernation level, and extreme hibernation level.

[0098] In one embodiment, optionally, both the first AAU and the first BBU include an optical module and a power module, the optical module and power module of the first AAU are connected, the optical module and power module of the first BBU are connected, and the optical module of the first AAU and the optical module of the first BBU are connected.

[0099] In the sleep state of the target sleep level, the optical module and power module of the first AAU are in a wake-up state, and the optical module and power module of the first BBU are in a wake-up state.

[0100] In one embodiment, optionally, in step S102, according to the first wake-up signal, controlling the module in the first BBU that is in a sleep state at the target sleep level to enter a wake-up state includes:

[0101] The power module in the first BBU is controlled to supply power to the module in the first BBU that is in a sleep state at the target sleep level.

[0102] In this embodiment of the invention, the power module in the first BBU is controlled to supply power to the module in the first BBU that is in a hibernation state at the target hibernation level so that it can enter the wake-up state.

[0103] In one embodiment, optionally, in step S103, a second wake-up signal is sent to the first AAU, including:

[0104] The first wake-up signal is sent from the optical module of the first BBU to the optical module of the first AAU.

[0105] In embodiments of the present invention, such as Figure 2 As shown, the optical modules of the first AAU and the first BBU can transmit signals via optical fiber. Of course, other cables capable of transmitting signals, such as RS485, can also be used. This embodiment of the invention does not impose any limitations on this.

[0106] Furthermore, the optical modules of the first BBU and the second BBU can also transmit signals via optical fiber.

[0107] In one embodiment, optionally, after sending the second wake-up signal to the first AAU in S103, the above method further includes:

[0108] Based on historical residency information, obtain the historical users of the first BBU;

[0109] Obtain the inter-frequency measurement information of the historical users;

[0110] Based on the inter-frequency measurement information, determine whether to migrate the historical user from the second base station to the first base station.

[0111] It should be noted that after the first BBU and the first AAU enter the wake-up state, the historical users of the first base station are obtained based on the historical camping information of the first base station. The historical users are currently camped on the second base station, and inter-frequency measurement is initiated for the historical users to obtain the inter-frequency measurement information of the historical users. Based on the inter-frequency measurement information and migration conditions, it is determined whether to migrate the historical users from the second base station back to the first base station.

[0112] Specifically, the migration condition could be that when the signal quality is below a quality threshold, historical users are migrated from the second base station back to the first base station.

[0113] like Figure 3 This is a flowchart illustrating the base station wake-up method according to an embodiment of the present invention. In this embodiment, the base station wake-up method includes the following steps:

[0114] S301, Obtain the historical camping information of users accessing the second base station.

[0115] S302, determine whether the number of users who have historically camped on the first base station is greater than the second user threshold.

[0116] If the judgment result of S302 is yes, then proceed to S303, and the first base station enters the wake-up process.

[0117] If the result of S302 is negative, then return to S301.

[0118] S304, the second BBU sends the first wake-up signal to the first BBU.

[0119] S305, the first BBU turns on the power to the module and enters the wake-up state.

[0120] S306, the first BBU sends a second wake-up signal to the first AAU.

[0121] S307, the first AAU turns on the power supply to the module and enters the wake-up state.

[0122] S308 initiates inter-frequency measurements for users who have historically camped at the first base station.

[0123] S309 determines whether the signal quality is below the quality threshold.

[0124] If the judgment result of S309 is yes, then proceed to S310 to migrate the historical user back to the first base station.

[0125] If the judgment result of S309 is negative, then proceed to S311 to keep the historical user camped on the second base station.

[0126] Embodiments of the present invention, such as Figure 4 As shown, a base station wake-up method is also provided, applied to a second BBU, the method comprising:

[0127] S401, a first wake-up signal is sent to the first BBU through the transmission link between the first BBU and the second BBU, wherein the first BBU belongs to the first base station and the second BBU belongs to the second base station.

[0128] In one embodiment, the transmission link may optionally include one of the following:

[0129] The optical module of the second BBU is connected to the optical module of the first BBU;

[0130] The second BBU and the first BBU are mounted on the back panel of the same chassis.

[0131] In one implementation, optionally, the first wake-up signal is sent by the second BBU to the first BBU when the second BBU determines that the first base station needs to enter a wake-up state based on the historical camping information of the currently accessed users of the second base station.

[0132] Embodiments of the present invention, such as Figure 5 As shown, a base station sleep method is also provided, applied to a first BBU, the method comprising:

[0133] S501 determines whether the first base station needs to enter a sleep state based on network load conditions.

[0134] In this embodiment of the invention, network load conditions include load rate and / or number of users. For example, when the number of users at the first base station is lower than a first user number threshold, it is determined that the first base station needs to enter a sleep state.

[0135] Optionally, it can be determined whether the first base station needs to enter sleep mode based on the network load of the first base station within a preset period.

[0136] S502, if it is determined that the first base station needs to enter a sleep state, the online users of the first base station are migrated to the second base station, and a sleep signal is sent to the first AAU. The sleep signal is used to indicate that the first AAU enters a sleep state of the target sleep level. The first base station includes the first BBU and the first AAU.

[0137] In this embodiment of the invention, when it is determined that the first base station needs to enter a sleep state, the online users of the first base station are migrated to the second base station, thereby ensuring normal communication for the online users. Then, a sleep signal is sent to the first AAU, and the first AAU shuts off the power supply to at least one module corresponding to the target sleep level according to the sleep signal, so as to enter the sleep state of the target sleep level.

[0138] The target hibernation level is one of shallow hibernation, deep hibernation, and extreme hibernation. The number of modules hibernating varies at different hibernation levels. It is understood that the number of modules hibernating at a shallow hibernation level is less than that at a deep hibernation level, and the number of modules hibernating at a deep hibernation level is less than that at an extreme hibernation level. However, the specific modules hibernating at different hibernation levels are not limited in this embodiment of the invention.

[0139] Optionally, a sleep signal is sent to the first AAU, including:

[0140] The sleep signal is sent from the optical module of the first BBU to the optical module of the first AAU.

[0141] In embodiments of the present invention, such as Figure 6 As shown, the optical modules of the first AAU and the first BBU can transmit signals via optical fiber. Of course, other cables capable of transmitting signals, such as RS485, can also be used. This embodiment of the invention does not impose any limitations on this.

[0142] S503, control at least one module in the first BBU corresponding to the target hibernation level to enter hibernation state.

[0143] In this embodiment of the invention, when the first AAU enters a sleep state of the target sleep level, the first BBU also enters a sleep state of the target sleep level, thereby realizing integrated sleep of AAU and BBU, reducing base station power consumption, and solving the problem of energy waste caused by not considering BBU sleep in the prior art.

[0144] like Figure 7 This is a schematic flowchart illustrating the base station sleep method according to an embodiment of the present invention. In this embodiment, the base station sleep method includes the following steps:

[0145] S701, obtain network load information within a preset period.

[0146] S702 determines whether the number of users in the network load situation is lower than the first user number threshold.

[0147] If the judgment result of S702 is yes, then proceed to S703, and the first base station enters the sleep state of the target sleep level.

[0148] If the result of S702 is yes, then return to S701.

[0156] Based on the network load and the threshold values ​​corresponding to different hibernation levels, the target hibernation level is determined. The target hibernation level is one of the shallow hibernation level, deep hibernation level, and extreme hibernation level.

[0157] In this embodiment of the invention, since the number of modules hibernating at the shallow hibernation level is less than the number of modules hibernating at the deep hibernation level, and the number of modules hibernating at the deep hibernation level is less than the number of modules hibernating at the extreme hibernation level, the threshold value corresponding to the shallow hibernation level is higher than the threshold value corresponding to the deep hibernation level, and the threshold value corresponding to the deep hibernation level is higher than the threshold value of the extreme hibernation level.

[0158] Network load conditions include load rate and / or number of users.

Under different sleep levels, the optical module and power module of the first AAU are both in a wake-up state, and the optical module and power module of the first BBU are also in a wake-up state, thus ensuring that they can receive wake-up signals to switch from sleep state to wake-up state.

Figure 8 (Not shown) is in the wake-up state, while other modules in the first BBU, such as the baseband board and the main control board, are in the sleep state, thereby maximizing power consumption and further reducing base station power consumption.

[0173] In one embodiment, optionally, according to the first wake-up signal, controlling the module in the first BBU that is in a sleep state at the target sleep level to enter a wake-up state includes:

[0174] The power module in the first BBU is controlled to supply power to the module in the first BBU that is in a sleep state at the target sleep level.
