Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.

In addition, because the position of the Pico RRU is close to that of the adjacent Pico RRU, the states of the Pico RRUs are correlated in space, and therefore the state control accuracy of the Pico RRU can be improved by controlling whether the Pico RRU is in a dormant state or not according to the states of the adjacent Pico RRUs. Moreover, after the status control is performed on the Pico RRU, the Pico RRU can be in a dormant state, and the power consumption is low when the Pico RRU is in the dormant state, so that after the status control is performed on the Pico RRU, the electric quantity can be saved, and the energy conservation is realized.

The following description is made of an application scenario and related concepts of the embodiments of the present application.

1. Application scenarios

The state control scheme provided by the embodiment of the application can be applied to an indoor environment, and the indoor environment is provided with a digital indoor distribution system. Referring to fig. 1, a schematic diagram of a digital indoor distribution system is shown. The digital indoor distribution system comprises: BBU, Rsub and PicoRRU1-PicoRRU5 a plurality of Pico RRUs. Wherein one BBU can connect multiple rhubs, for example, one BBU can connect at least 10 rhubs. One Rhub may connect multiple Pico RRUs, e.g., one Rhub may connect up to 8 Pico RRUs.

The BBU is used for processing baseband signals. The Rsub and each Pico RRU can be connected in a star shape, and provide data aggregation and distribution functions for the BBU and the Pico RRU. Specifically, in the downlink communication process, after receiving downlink data sent by the BBU, the RHub performs shunting processing on the downlink data, and then sends the data after shunting processing to the Pico RRU; in the uplink communication process, the Rhub receives uplink data sent by the Pico RRU, converges the received uplink data, and sends the converged data to the BBU. Additionally, Rpub may also power the Pico RRU.

It should be noted that, since the communication connection relationship between different rhubs and the BBU and the Pico RRU is the same, fig. 1 only shows one RHub in communication connection with the BBU. In addition, fig. 1 shows only the communication connection relationship between the respective devices, and does not show the physical location relationship between the respective devices.

Specifically, the indoor environment may be a teaching building of a school, a dormitory, a mall, an airport, an office building, a gym, or the like.

In view of the foregoing, in an embodiment of the present application, an execution subject of the embodiment of the present application may be any Pico RRU in the digital indoor distribution system.

Since the digital indoor distribution system is deployed in an indoor environment, some Pico RRUs are deployed at the entrance of the environment, and some Pico RRUs are deployed in the indoor environment. In an embodiment of the present application, in order to ensure that the terminal can timely enjoy the communication service provided by the digital indoor distribution system when entering the environment, the Pico RRU disposed at the entrance may be configured to be always in an active state. Based on the above situation, in one case, the execution main body of the embodiment of the present application may be any Pico RRU except for the Pico RRU at the entrance in the digital indoor distribution system.

2. Concept of concern

After the Pico RRU is powered on and started, the running devices are different, and the power consumption is different. The power consumption is higher under the condition that more devices are operated, and on the contrary, the power consumption is lower under the condition that less devices are operated. Based on this, the Pico RRU can be considered to be in different states according to the number of devices operated by the Pico RRU and the power consumption difference.

In an embodiment of the present application, the above states may include: an active state and a dormant state. When the Pico RRU is in an activated state, the Pico RRU can timely respond to the request of the terminal and interact with devices such as RHUB and the like. When the Pico RRU is in the sleep state, since part of devices in the Pico RRU are not operated, that is, part of devices are in sleep, the Pico RRU needs to be awakened first, that is, to transition to the active state, so as to interact with the terminal, the RHub, and other devices.

In another embodiment of the application, as more devices are dormant in the Pico RRU, the power consumption is smaller, the longer the time required for waking up the Pico RRU, the fewer devices are dormant, the larger the power consumption is, and the shorter the time required for waking up the Pico RRU, based on which, the dormant state can be further subdivided and divided into different levels of dormant states. For example, a shallow sleep state and a deep sleep state are classified. And the power consumption of the Pico RRU in the shallow layer dormant state is larger than that in the deep layer dormant state.

For example, the time required for Pico RRU to transition from a shallow sleep state to an active state may be 10 seconds, while the time required to transition from a deep sleep state to an active state may be 100 seconds.

The state control method, the Pico RRU, the state control apparatus, and the processor-readable storage medium provided in the embodiments of the present application are respectively described in detail below with specific embodiments.

Referring to fig. 2, a flowchart of a first state control method applied to a first Pico RRU is provided. The first Pico RRU may be any Pico RRU in the indoor distribution system or any Pico RRU in the digital indoor distribution system described above except for the Pico RRU at the entrance.

Specifically, the state control method includes the following steps S201 to S202.

Step S201: and acquiring the state of the adjacent Pico RRU of the first Pico RRU under the condition that the first Pico RRU has no access terminal and the state meets the energy-saving triggering condition.

After entering the coverage area of the Pico RRU, the terminal accesses the Pico RRU, so the above access terminal may be understood as: a terminal that has access to Pico RRU. In one case, the first Pico RRU may count the number of terminals that have access to the first Pico RRU according to a preset period, and when the number is greater than 0, the first Pico RRU may be considered to have an access terminal, and when the number is equal to 0, the first Pico RRU may be considered to have no access terminal. In another case, the first Pico RRU may also detect the access terminal, and consider that the first Pico RRU has the access terminal as long as it is detected that there is terminal access, otherwise, consider that the first Pico RRU has no access terminal if it is not detected that there is terminal access within a certain time period.

The state of the first Pico RRU satisfies the energy saving triggering condition, and it can be considered that there is a space for energy saving optimization for the first Pico RRU. That is, the energy-saving triggering condition represents that the Pico RRU has an energy-saving optimization space.

Based on the above situation, in an embodiment of the present application, when the status of the Pico RRU includes an active status and a dormant status, the energy saving trigger condition may be that the first Pico RRU is in the active status. So that the state of the first Pico RRU can transition from the active state to the dormant state. Since the power consumption of the Pico RRU in the dormant state is less than the power consumption in the active state, an energy-saving optimization space exists when the first Pico RRU is in the active state.

In another embodiment of the present application, in a case that the status of the Pico RRU includes an active status and a dormant status, and the dormant status can be subdivided into a shallow dormant status and a deep dormant status, the above-mentioned power saving triggering condition may be that the first Pico RRU is in the active status or the shallow dormant status. Thus the state of the first Pico RRU can transition from an active state to a shallow sleep state, a deep sleep state, or from a shallow sleep state to a deep sleep state. Since the power consumption of the Pico RRU in the shallow sleep state is less than that in the active state, and the power consumption in the deep sleep state is less than that in the shallow sleep state, an energy-saving optimization space exists when the first Pico RRU is in the active state or the shallow sleep state.

For example, the power consumption of the Pico RRU may be about 50-80W in the active state, about 35-60W in the shallow sleep state, and about 0W in the deep sleep state.

In addition, under the condition that the state of the first Pico RRU does not satisfy the energy saving triggering condition, the scheme provided by the embodiment of the present application may be executed again from step 201 at a certain time interval.

In another embodiment of the application, after it is determined that the first Pico RRU has no access terminal and the state satisfies the energy saving triggering condition, timing may be started, and after the timing duration reaches a preset duration, the state of the adjacent Pico RRU of the first Pico RRU is obtained.

Since the adjacent Pico RRUs of the first Pico RRU are generally located closer to the first Pico RRU, the terminal may be mobile, which may cause the states of the adjacent Pico RRUs to change. In addition, the neighboring Pico RRU also requires reaction time to complete the state transition. Therefore, in this embodiment, after it is determined that the first Pico RRU has no access terminal and the state satisfies the energy saving triggering condition, the state of the adjacent Pico RRU is obtained at a preset time interval, and at this time, the state of the adjacent Pico RRU is relatively stable and the accuracy is higher.

Specifically, when the first Pico RRU starts timing, a timer may be started to perform timing. Therefore, the timing duration of the timer can be set to be the preset duration, the timer counts down, and the timing duration can be considered to reach the preset duration when the counting down is finished. In addition, a timer can be started for timing. And after the timing duration of the timer reaches the preset duration, ending the timing, and executing the subsequent steps to obtain the state of the adjacent Pico RRU.

Step S202: and controlling whether the first Pico RRU is in a dormant state or not according to the obtained state of the adjacent Pico RRU.

Since the location where the adjacent Pico RRUs are located is closer to the location where the first Pico RRU is located, and the probability that the terminal moves from the coverage area of the first Pico RRU to the coverage area of the adjacent Pico RRU is higher, it can be considered that the state of the first Pico RRU and the state of the adjacent Pico RRU have a correlation.

In an embodiment of the application, when controlling whether the first Pico RRU is in the dormant state according to the state of the adjacent Pico RRU, whether the first Pico RRU is in the dormant state may be controlled according to the number of the Pico RRUs in the dormant state in the adjacent Pico RRU or the occupation ratio of the Pico RRU in the dormant state in the adjacent Pico RRU.

For example, if the number of Pico RRUs in a sleep state in neighboring Pico RRUs is greater than a preset number, the first Pico RRU may be controlled to be in the sleep state. For example, the predetermined number may be 3, 4, etc.

And if the occupation ratio is larger than the preset occupation ratio, controlling the first Pico RRU to be in a dormant state. For example, the predetermined ratio may be 70%, 75%, or the like.

It should be noted that whether the first Pico RRU is in the sleep state may also be controlled in other manners, and a specific implementation manner is described in the following embodiments and will not be described in detail here.

In addition, in the case that the status of the Pico RRU includes an active status and a dormant status, whether the first Pico RRU is in the dormant status may be to control the first Pico RRU to be in the dormant status, that is, to transition from the active status to the dormant status, or to control the first Pico RRU not to be in the dormant status, that is, to still maintain to be in the active status.

In the case that the status of the Pico RRU includes an active status and a dormant status, and the dormant status can be subdivided into a shallow dormant status and a deep dormant status, whether the first Pico RRU is in the dormant status may be controlled to be in the shallow dormant status or the deep dormant status, that is, to transition from the active status to the shallow dormant status or the deep dormant status, or to be controlled not to perform the status transition, and the original status is maintained.

As can be seen from the above, when the scheme provided by the embodiment of the application is applied to control the state of the Pico RRU, it is considered whether the Pico RRU has an access terminal and whether the state of the Pico RRU satisfies the energy saving triggering condition. And on the basis, controlling whether the Pico RRU is in a dormant state or not according to the states of the adjacent Pico RRUs of the Pico RRU. Whether the Pico RRU has the access terminal or not and the state of the Pico RRU are not necessarily related to the working time of the indoor environment but are related to the dynamic occurrence of the terminal in the environment, so the flexibility of controlling the state of the Pico RRU can be improved by applying the scheme provided by the embodiment of the application.

Moreover, after the status control is performed on the Pico RRU, the Pico RRU can be in a dormant state, and the power consumption is lower when the Pico RRU is in the dormant state, so that after the status control is performed on the Pico RRU, the electric quantity can be saved, and the energy conservation is realized.

Referring to fig. 3, a flowchart of a second state control method is provided, and compared with the foregoing embodiment shown in fig. 1, in this embodiment, the step S202 described above controls whether the first Pico RRU is in a sleep state according to the obtained state of the adjacent Pico RRU, which can be implemented by the following steps S202A and S202B.

Step S202A: and controlling the first Pico RRU to be in a dormant state under the condition that the obtained state of the adjacent Pico RRUs represents that each adjacent Pico RRU of the first Pico RRU is in the dormant state.

Because the position of the adjacent Pico RRUs of the first Pico RRU is closer to the position of the first Pico RRU, when each adjacent Pico RRU is in a dormant state, a terminal can be considered to be absent around the area covered by the first Pico RRU, so that the probability that a terminal enters the area covered by the first Pico RRU within a certain time is low, and the first Pico RRU can be controlled to be in the dormant state to save electric quantity.

Step S202B: and under the condition that the obtained state of the adjacent Pico RRUs indicates that the Pico RRU in the activated state exists in the adjacent Pico RRUs of the first Pico RRU, if the second Pico RRU does not exist in the adjacent Pico RRU, controlling the first Pico RRU to be in a dormant state.

Wherein the second Pico RRU is: there is a Pico RRU for the access terminal.

In this case, although there is a Pico RRU in an active state in the adjacent Pico RRUs, there is no Pico RRU having an access terminal, so there is no terminal in the coverage area of the adjacent Pico RRUs, and therefore, it can also be considered that there is no terminal around the area covered by the first Pico RRU, and the probability that a terminal enters the area covered by the first Pico RRU within a certain time period is low, and the first Pico RRU can be controlled to be in a dormant state, so as to save power.

In addition, under the condition that the obtained state of the adjacent Pico RRUs indicates that the Pico RRUs in the activated state exist in the adjacent Pico RRUs of the first Pico RRU, if a second Pico RRU exists in the adjacent Pico RRUs, it is indicated that a terminal exists in the coverage area of the adjacent Pico RRU, that is, the terminal exists around the area covered by the first Pico RRU, and since the terminal is movable, there is a possibility that the terminal moves to the area covered by the first Pico RRU. In this case, the first Pico RRU may not perform state transition and keep the original state unchanged.

From the foregoing description of the concept, the sleep state may include a shallow sleep state and a deep sleep state, so in an embodiment of the present application, in the step S202A, in a case that the obtained state of the adjacent Pico RRUs indicates that each adjacent Pico RRU is in the sleep state, the first Pico RRU is controlled to be in the sleep state, and specifically, in a case that the obtained state of the adjacent Pico RRU indicates that each adjacent Pico RRU is in the shallow sleep state or the deep sleep state, the first Pico RRU is controlled to be in the deep sleep state. Therefore, the first Pico RRU can directly jump to the deep sleep state no matter in the active state or in the shallow sleep state, and the electric quantity can be greatly saved.

In the step S202B, if the second Pico RRU does not exist in the adjacent Pico RRU, the first Pico RRU is controlled to be in the sleep state, and specifically, if the second Pico RRU does not exist in the adjacent Pico RRU, the first Pico RRU is controlled to be in the shallow sleep state. On the one hand, if there is a Pico RRU in an active state in the neighboring Pico RRUs, it can be considered that a terminal exists in an area covered by the neighboring Pico RRU recently, and considering that the terminal has a mobile characteristic, it can be considered that there is a possibility that the terminal enters the area covered by the first Pico RRU. On the other hand, the time required to transition from the deep sleep state to the active state is longer than the time required to transition from the shallow sleep state to the active state. Therefore, in the above two aspects, in the above case, not only power can be saved by controlling the first Pico RRU to be in the shallow sleep state, but also once a terminal enters the coverage area of the first Pico RRU, the first Pico RRU can quickly transition to the active state to provide service for the terminal.

As can be seen from the above, when the scheme provided by the above embodiment is applied to the state control, it is not only ensured that the first Pico RRU is in the dormant state when each adjacent Pico RRU of the first Pico RRU is in the dormant state, but also ensured that the first Pico RRU is also in the dormant state when the active Pico RRU exists in the adjacent Pico RRUs and the second Pico RRU does not exist. Therefore, the flexibility of state control on the Pico RRU is higher, and the power saving is facilitated.

Referring to fig. 4, a flowchart of a third state control method is provided, and compared with the foregoing embodiment shown in fig. 1, in this embodiment, the state control method may further include step S203.

Step S203: and after the first Pico RRU is in the dormant state, if a first activation signal is received, controlling the first Pico RRU to make state transition forward to an adjacent state.

Wherein the forward neighbor state is: and the state which is adjacent to the current state of the first Pico RRU and corresponds to the power consumption which is larger than the power consumption corresponding to the current state. That is, the power consumption of the Pico RRU in the forward neighbor state is greater than the power consumption in the current state.

The first activation signal may be: and the Pico RRU in the adjacent Pico RRUs generates a signal sent to the first Pico RRU after the state transition and the transition to the activated state. The first activation signal may also be: and the Pico RRU in the adjacent Pico RRUs detects a signal sent to the first Pico RRU after the terminal is accessed.

Specifically, since the power consumption of the Pico RRU in the forward adjacent state is greater than that in the current state, and the power consumption of the Pico RRU in the active state is the largest, after the forward adjacent state is transited, the state of the Pico RRU gets closer to the active state, and even transits to the active state.

For example, if the status of the Pico RRU includes an active status and a dormant status, the two statuses are adjacent statuses, and the power consumption of the Pico RRU in the active status is greater than the power consumption of the Pico RRU in the dormant status, then the forward adjacent status is the active status when the status of the Pico RRU is the dormant status.

If the status of the Pico RRU comprises an activated status and a dormant status, and the dormant status can be subdivided into a shallow dormant status and a deep dormant status, the activated status, the shallow dormant status and the deep dormant status are adjacent in sequence, the power consumption of the Pico RRU in the activated status is greater than that in the shallow dormant status, the power consumption of the Pico RRU in the shallow dormant status is greater than that in the deep dormant status, when the Pico RRU is in the deep dormant status, the forward adjacent status is the shallow dormant status, and when the Pico RRU is in the shallow dormant status, the forward adjacent status is the activated status.

As can be seen from the above, in the scheme provided in this embodiment, after the first Pico RRU is in the dormant state, the first Pico RRU can be wakened up layer by the adjacent Pico RRU, so that the flexibility of state control is further improved.

Based on the above embodiment, after the first Pico RRU performs the state transition forward to the adjacent state, it may be possible to be in the activated state again, and in view of this, in an embodiment of the present application, after the first Pico RRU is in the activated state again, a second activation signal may be sent to each adjacent Pico RRU, so that each adjacent Pico RRU performs the state transition forward to the adjacent state.

Since the coverage area of the first Pico RRU may already have the terminal after the first Pico RRU is in the activated state, or there is a high probability that the terminal enters, considering the mobility of the terminal, the probability that the area covered by the neighboring Pico RRU of the first Pico RRU enters the terminal is also high. In view of this, in the scheme provided in this embodiment, after the first Pico RRU is in the activated state again, the activation signal is sent to each adjacent Pico RRU, so that each adjacent Pico RRU can be awakened layer by layer in time to prepare for providing a service to the terminal, and therefore, the communication effect for the terminal can be effectively ensured while the power is saved.

In the case that the states of the Pico RRU include an active state, a shallow sleep state, and a deep sleep state, the transition process between the states mentioned in the above embodiments is organized as shown in fig. 5. In the state transition diagram shown in fig. 5, the reference numerals on the arrow side indicate conditions for performing a state transition.

Wherein the condition (1) is a condition for transition from an active state to a deep sleep state: and each adjacent Pico RRU is in a shallow dormant state or a deep dormant state.

The condition (2) is a condition for transitioning from the shallow sleep state to the deep sleep state: and each adjacent Pico RRU is in a shallow dormant state or a deep dormant state.

The condition (3) is a condition for transition from the active state to the shallow sleep state: and the adjacent Pico RRUs comprise the Pico RRU in an activated state, and the Pico RRU with the access terminal does not exist in the adjacent Pico RRUs.

The condition (4) is a condition for transitioning from the shallow sleep state to the active state: and the Pico RRU in the adjacent Pico RRU is in an activated state, or the Pico RRU in the adjacent Pico RRU detects that the terminal is accessed.

The condition (5) is a condition for transitioning from the deep sleep state to the shallow sleep state: and the Pico RRU in the adjacent Pico RRUs is in an activated state.

The following describes a state control scheme provided in the embodiment of the present application by way of specific examples with reference to fig. 1 and 5.

It is assumed that PicoRRU1 is disposed at an indoor environment entrance, configured to be always in an active state. No access terminal currently exists for any of PicoRRU1-PicoRRU 5. The current status of each Pico RRU and the neighboring Pico RRUs are shown in table 1 below.

TABLE 1

Pico RRU	Current state	Adjacent Pico RRU
			PicoRRU1	Active state	PicoRRU2、PicoRRU3
PicoRRU2	Active state	PicoRRU1、PicoRRU3、PicoRRU4、PicoRRU5
			PicoRRU3	Shallow sleep state	PicoRRU1、PicoRRU2
PicoRRU4	Shallow sleep state	PicoRRU2、PicoRRU5
			PicoRRU5	Deep sleep state	PicoRRU2、PicoRRU4

For PicoRRU2, there is no access terminal, of its neighboring picorrus, PicoRRU1 is in an active state, PicoRRU3 and PicoRRU4 are both in a shallow sleep state, PicoRRU5 is in a deep sleep state, and there is no access terminal for these neighboring picorrus, so PicoRRU2 can be controlled to be in a shallow sleep state, i.e., to transition from an active state to a shallow sleep state.

For the PicoRRU3, there is no access terminal, the PicoRRU1 in its neighboring picorrus is in an active state, the PicoRRU2 has transitioned to a shallow sleep state, and there is no access terminal for these neighboring picorrus, so the PicoRRU3 can be controlled to be in the shallow sleep state, i.e., the status of the PicoRRU3 remains unchanged.

For the PicoRRU4, there is no access terminal, of its neighboring picorrus, the PicoRRU2 has transitioned to the shallow sleep state, the PicoRRU3 is in the shallow sleep state, and there is no access terminal for these neighboring picorrus, so the PicoRRU4 can be controlled to be in the deep sleep state, i.e., to transition from the shallow sleep state to the deep sleep state.

The PicoRRU5 is already in a deep sleep state, and there is no energy saving optimization space, that is, its state does not satisfy the energy saving triggering condition, so the state control is not performed according to the scheme provided in the embodiment of the present application.

Assume that a terminal enters the coverage area of PicoRRU1 and accesses PicoRRU1 when it moves to the entrance of the indoor environment. The PicoRRU1 detects that a terminal is accessed, and sends a first activation signal to the PicoRRU2 and the PicoRRU3 in the adjacent picorrus. The PicoRRU2 and the PicoRRU3 are both in shallow sleep states at this time, such that the forward adjacent states of the PicoRRU2 and the PicoRRU3 are active states, and after receiving the first activation signal, a state transition is made to the forward adjacent states, transitioning to the active states.

Since the PicoRRU2 and the PicoRRU3 have transitioned to the active state, a first activation signal is sent to the respective neighboring PicoRRU. Specifically, after the PicoRRU2 sends the first activation signal to the PicoRRU1, the PicoRRU3, the PicoRRU4 and the PicoRRU5, since the PicoRRU1 is configured to be always in the activation state and the PicoRRU3 is already in the activation state, the PicoRRU1 and the PicoRRU3 do not need to respond to the first activation signal, the PicoRRU4 and the PicoRRU5 are in the deep sleep state, and the forward adjacent state of the PicoRRU4 and the PicoRRU5 is the shallow sleep state, and the forward adjacent state transitions to the shallow sleep state by one layer.

Corresponding to the state control method, the embodiment of the application also provides a Pico RRU.

Referring to fig. 6, an embodiment of the present application provides a schematic structural diagram of a Pico RRU, which serves as a first Pico RRU and includes a memory 601, a transceiver 602, and a processor 603;

the memory 601 is used for storing computer programs; the transceiver 602, configured to transceive data under the control of the processor 603; the processor 603 is configured to read the computer program in the memory 601 and perform the following operations:

Specifically, the memory 601, the transceiver 602, and the processor 603 are communicatively connected to a bus interface, and communication is achieved through the bus interface.

Wherein in fig. 6 the bus architecture may comprise any number of interconnected buses and bridges, with one or more processors, represented by the processor 603, and various circuits of the memory, represented by the memory 601, being linked together. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, power management circuits, and the like, which are well known in the art, and therefore, will not be described any further herein. The bus interface provides an interface. The transceiver 602 may be a plurality of elements including a transmitter and receiver that provide a means for communicating with various other apparatus over a transmission medium including wireless channels, wired channels, fiber optic cables, and the like. The processor 603 is responsible for managing the bus architecture and general processing, and the memory 601 may store data used by the processor 603 in performing operations.

The processor 603 may be a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or a Complex Programmable Logic Device (CPLD), and may also have a multi-core architecture.

Whether the Pico RRU has the access terminal or not and the state of the Pico RRU are not necessarily related to the working time of the indoor environment but are related to the dynamic occurrence of the terminal in the environment, so the flexibility of controlling the state of the Pico RRU can be improved by applying the scheme provided by the embodiment of the application. In addition, because the position of the Pico RRU is close to that of the adjacent Pico RRU, the states of the Pico RRUs are correlated in space, and therefore the state control accuracy of the Pico RRU can be improved by controlling whether the Pico RRU is in a dormant state or not according to the states of the adjacent Pico RRUs. Moreover, after the status control is performed on the Pico RRU, the Pico RRU can be in a dormant state, and the power consumption is lower when the Pico RRU is in the dormant state, so that after the status control is performed on the Pico RRU, the electric quantity can be saved, and the energy conservation is realized.

controlling the first Pico RRU to be in a dormant state under the condition that the obtained state of the adjacent Pico RRUs represents that each adjacent Pico RRU is in the dormant state;

and obtaining the state of the adjacent Pico RRU of the first Pico RRU after the timing duration reaches the preset duration.

Since the adjacent Pico RRUs of the first Pico RRU are generally located closer to the first Pico RRU, the terminal may be mobile, which may cause the status of the adjacent Pico RRUs to change. In addition, the neighboring Pico RRUs also require reaction time to complete the state transition. Therefore, in this embodiment, after it is determined that the first Pico RRU has no access terminal and the state satisfies the energy saving triggering condition, the state of the adjacent Pico RRU is obtained at intervals of a preset duration, and at this time, the state of the adjacent Pico RRU is relatively stable and the accuracy is higher.

Since the coverage area of the first Pico RRU may already have the terminal after the first Pico RRU is activated, or there is a high probability that the terminal enters, the probability that the area covered by the neighboring Pico RRU of the first Pico RRU enters the terminal is also high in consideration of mobility of the terminal. In view of this, in the scheme provided by this embodiment, after the first Pico RRU is in the activated state again, the activation signal is sent to each adjacent Pico RRU, so that each adjacent Pico RRU can be wakened up layer by layer in time to prepare for providing a service to the terminal, and thus, the power can be saved and the communication effect for the terminal can be effectively ensured.

In addition, because the position of the Pico RRU is close to that of the adjacent Pico RRU, the states of the Pico RRUs are correlated in space, and therefore the state control accuracy of the Pico RRU can be improved by controlling whether the Pico RRU is in a dormant state or not according to the states of the adjacent Pico RRUs. Moreover, after the status control is performed on the Pico RRU, the Pico RRU can be in a dormant state, and the power consumption is low when the Pico RRU is in the dormant state, so that after the status control is performed on the Pico RRU, the electric quantity can be saved, and the energy conservation is realized.
