However, because the signal coverage areas of the adjacent cell and the energy-saving cell in the actual network cannot be completely overlapped, the service load of the adjacent cell cannot accurately reflect the service requirement under the energy-saving cell, so that the inertia moment of the energy-saving cell is not accurate enough and cannot be matched with the actual service requirement of the energy-saving cell.
Another energy-saving technology is also proposed in the industry as a timing wake-up technology, and the energy-saving cell enters a turn-off state and a working state at a designated time according to a preset turn-off time and a wake-up time, but the turn-off time and the wake-up time are both statically configured, and cannot dynamically adapt to the service demand change of the energy-saving cell.

For ease of understanding, related art terms related to the present application will be explained first.
Detecting signals, wherein each cell in a preset area corresponds to a different detecting signal; a detection signal corresponds to a detection period, a detection frequency band and a transmission period; different detection signals occupy different time-frequency resources respectively; the detection signals comprise but not limited to detection time periods, detection frequency bands and sending period information corresponding to the detection signals; the detection signal information comprises a detection period, a detection frequency band and a transmission period corresponding to the detection signal, and the detection period, the detection frequency band and the transmission period can be preset in a base station where each cell is located in a preset area.
Different detection signals are orthogonal in time domain or frequency domain, namely, non-overlapping time domain resources or frequency domain resources are occupied; the detection period comprises a plurality of symbols in one system frame, and the symbols can be represented by symbol identifiers; the detection frequency band comprises a plurality of subcarriers in a cell working frequency band, and can be represented by subcarrier identification; for example, for probe signal 1, the corresponding probing period is { symbol3, symbol6, symbol9}, probing frequency band is { subsuccarrier 3, subsuccarrier 6, subsuccarrier 9}; for probe signal 2, the corresponding probing period is { symbol4, symbol6, symbol10}, the probing frequency band is { subsuccarrier 4, subsuccarrier 7, subsuccarrier 10}.
The transmission periods of different detection signals can be the same or different; the probing signal transmission period may be expressed as a duration of several system frames; for example, the transmission period of the probe signal 1 is a duration of 10 system frames, and the transmission period of the probe signal 2 is a duration of 20 system frames.
The detection signal information corresponding to each cell is sent to the terminal through a first message; the first message is sent to the terminal by the cell, and the sending mode can be a cell system broadcast message or an RRC message; the first message carries the detection signal corresponding to the cell.
When the cell is in a working state, a first message can be sent to the terminal; when the cell is in an off state, the first message is not sent any more; the energy-saving cell and the target terminal respectively receive or transmit the detection signals in the detection time period and the detection frequency band according to the transmission period of the detection signals.
The energy-saving cell is a cell in an off state. The power save cell may determine when to enter an off state based on traffic load to achieve base station power saving. For example, when the traffic load statistic value of the energy-saving cell in the preset historical time is smaller than the shutdown threshold value, or the traffic load predicted value in the future time is smaller than the shutdown threshold value, the energy-saving cell enters the shutdown state.
And the cells are associated, and are cells which meet the service requirements of the terminal or are accessed preferentially. For example, if the terminal is a private network terminal, the associated cell is a private network cell.
The monitoring period, to determine the period of the wake-up time, may comprise a plurality of consecutive probing periods.
At present, after an energy-saving cell in a cell shutdown technology enters a shutdown state, a neighboring cell in the same area determines the wake-up time of the energy-saving cell based on the self traffic load, namely, when the traffic load of the neighboring cell is greater than a preset threshold value, the energy-saving cell in the shutdown state is waken up, so that the energy-saving cell enters a working state, and wake-up based on the traffic load of the neighboring cell is realized. However, in the technology, because the signal coverage areas of the adjacent cell and the energy-saving cell in the actual network cannot be completely overlapped, the service load of the adjacent cell cannot accurately reflect the service requirement under the energy-saving cell.
In the timing wake-up technology, the energy-saving cell can enter a working state at a designated time according to a preset wake-up time, so that wake-up based on timing information is realized. However, in the timing wake-up technology, the wake-up time is statically configured, and the service requirement change of the energy-saving cell cannot be dynamically adapted.
Therefore, the existing energy-saving cell wake-up method can cause inaccurate wake-up time of the energy-saving cell and cannot be matched with the actual service requirement of the energy-saving cell. Therefore, the energy-saving cell is possibly awakened when the actual service requirement of the energy-saving cell is smaller, so that the resource waste of the energy-saving cell is caused, and the energy-saving effect is influenced; the energy-saving cell may not be awakened in time when the actual service requirement of the energy-saving cell is large, so that the access requirement of a terminal (UE) cannot be met, and the service performance of the UE is affected.
Based on the above, the application provides a wake-up method of an energy-saving cell, which has the following basic principles: after receiving a detection signal sent by a target terminal, the energy-saving cell determines the wake-up time of the energy-saving cell according to the detection signal, and then enters a working state at the wake-up time and is accessed to the target terminal.
According to the application, after the detection signal with the actual service of the target terminal sent by the target terminal is received, the wake-up time of the energy-saving cell is determined according to the detection signal, and the energy-saving cell enters the working state at the wake-up time, and the wake-up time of the energy-saving cell can be accurately determined by combining the actual service requirement of the target terminal, so that the wake-up time of the energy-saving cell is matched with the actual service requirement of the energy-saving cell, the on-demand wake-up of the energy-saving cell is realized, and the energy-saving effect and the service performance are both considered.
The following describes in detail the implementation of the embodiment of the present application with reference to the drawings.
The scheme provided by the application can be applied to the wake-up system 100 of the energy-saving cell illustrated in fig. 1, and the system comprises: a power saving cell 101, a target terminal 102.

The target terminal 102 is configured to determine, according to the cell information, the energy-saving cell 101 corresponding to the target terminal 102, and then send a probe signal to the energy-saving cell 101 according to the target power.

Specifically, as shown in fig. 2, the target terminal 102 may include: a first terminal 103 and a second terminal 104. The wake-up system 100 of the energy saving cell may further include: serving cell 105.

The target terminal obtains the working state of the access cell.

And finally, determining the candidate cell with the minimum distance with the target terminal as the energy-saving cell corresponding to the target terminal from the candidate cells with the distance between the target terminals smaller than the preset distance threshold.
In another possible implementation manner, the cell information is a migration indication message sent by the current serving cell of the target terminal. The migration indication message includes: and the energy-saving cell identification corresponding to the target terminal. The energy-saving cell may be the same coverage cell with the smallest service load, where the working state in the same coverage cell of the service cell is in an off state when the service load of the service cell is greater than a load threshold. Or, the energy-saving cell may be a coverage cell in which the service rate average value in the history time is not less than the expected rate of the target terminal or the service delay average value in the history time is not greater than the expected delay of the target terminal when the service load of the service cell is not greater than the load threshold.
The target terminal determines an energy-saving cell corresponding to the target terminal according to the cell information, and the method comprises the following steps: and the target terminal determines the energy-saving cell corresponding to the target terminal according to the identification of the energy-saving cell.
The serving cell sends a migration indication message to the target terminal when the serving cell meets a preset condition. The migration indication message carries an identifier of the terminal, an identifier of an energy-saving cell corresponding to the terminal, a corresponding detection signal and migration indication information. And in the monitoring period, if the target terminal receives the migration indication message sent by the service cell, determining the energy-saving cell corresponding to the target terminal according to the identification of the energy-saving cell.
When the service cell meets the preset condition, the process of sending the migration indication message to the target terminal specifically comprises the following steps:
the service cell acquires the history information of each same coverage cell according to the monitoring period.
It should be noted that, the process of the serving cell obtaining the history information of each same coverage cell may send a history information request message to each same coverage cell according to a monitoring period for the serving cell. Wherein the indication information of the cell information request carries the service cell identification. In response, each co-coverage cell transmits a cell information indication message to the serving cell after receiving the history information request message transmitted by the serving cell. The cell information indication message carries the same coverage cell identification and cell history information.
The process of the serving cell obtaining the history information of each same coverage cell may also send a cell information indication message to the serving cell for each same coverage cell according to the monitoring period. The historical information comprises a service load average value, a service rate average value and a service time delay average value of a cell in historical time; the same coverage area exists between the same coverage area and the service area, and the same coverage area identifier corresponding to each cell can be preset in the base station.
And the service cell determines a target terminal and a corresponding energy-saving cell according to the history information of the same coverage cell.
Specifically, if the same coverage cells of the service cell are in an off state and the service load of the service cell is greater than a preset load threshold, determining an edge terminal under the service cell as a target terminal. The signal intensity of the serving cell received by the edge terminal is smaller than a signal intensity threshold. The service cell determines the edge terminal according to the measurement report sent by the terminal, and the measurement report carries the signal intensity of the service cell measured by the terminal. The service cell determines any one of the coverage cells or one with the smallest service load as the energy-saving cell corresponding to the target terminal.
And if the same coverage cells of the service cell are in an off state, the service load of the service cell is not more than a load threshold value, and the service rate of any terminal in the service cell is less than the expected rate of the terminal or the service delay of the terminal is more than the expected delay of the terminal, determining the terminal as a target terminal. The expected rate and the expected time delay of the terminal can be obtained from a service request message sent by the terminal, and also can be obtained from core network equipment connected with a serving cell.
And if the average value of the service rates of the same coverage cells in the historical time is not smaller than the expected rate of the target terminal or the average value of the service delays of the same coverage cells in the historical time is not larger than the expected delay of the target terminal, determining the same coverage cells as the energy-saving cells corresponding to the terminal.
It should be noted that, the serving cell may determine whether the same coverage cell is currently in an off state according to the deactivation indication message and the activation indication message sent by the same coverage cell. Specifically, if the deactivation indication message sent by the same coverage cell and received at the first time before the current time is not received after the first time, the same coverage cell is considered to be in the off state. The deactivation indication message and the activation indication message are respectively used for indicating that the cell is in an off state and enters the working state from the off state.
S302, the target terminal sends a detection signal to the energy-saving cell according to the target power.
The target power is the sum of the preset power of the target terminal and the path loss power of the signal sent by the target terminal to the energy-saving cell.
Specifically, in each monitoring period, the target terminal transmits a detection signal in a target detection period and a target detection frequency band according to a target transmission period, and the transmission power of the detection signal is the target power.
The target sending period, the target detecting period and the target detecting frequency range are determined according to the detecting signal information of the energy-saving cell corresponding to each monitoring period.
The target power value may be determined according to a distance between the target terminal and the corresponding energy-saving cell. The greater the distance, the greater the target power value.
One possible implementation manner, the target power corresponding to the target terminal=the preset power+the path loss power.
The path loss power may be determined according to a distance between the target terminal and the corresponding energy-saving cell and a path loss formula. The path loss formula is used for reflecting the corresponding relation between the distance between the transceiver devices and the path loss value, and the existing path loss formula can be adopted. Propagation models defined by 3GPP 36.873 and 3GPP 38.901 can be employed for 4G and 5G systems, respectively. The method comprises the steps of including urban micro base stations (urba n microcel l, UMi), urban macro base stations (uban macro l, UMa), rural macro l, RMa and indoor hot spot (InH), wherein each scene is divided into a line-of-sight (LOS) condition and a non-line-of-sight (NLOS) condition, and corresponding path LOSs formulas are respectively defined.
Illustratively, using the UMa model for line-of-sight (LOS), the path LOSs equation is as follows:
Path loss＝28.0+22*log10(d)+20log10(fc)
where Path loss denotes Path loss power, d denotes a distance between the target terminal and the energy saving cell, and fc denotes a target probing frequency of the target terminal.
The path loss power can be calculated according to the distance between the target UE and the corresponding energy-saving cell and the carrier center frequency of the energy-saving cell by using the formula.
The preset power value is related to the receiving sensitivity of the base station where the energy-saving cell is located, and is the minimum power value meeting the signal detection requirement of the base station.
S303, the energy-saving cell receives the detection signal sent by the target terminal.
Wherein the target terminal comprises one or more of the following: the terminal receives the access failure indication message sent by the cell and the terminal receives the migration indication message sent by the current service cell of the terminal. The energy-saving cell opens an uplink channel at each detection period according to the detection signal information corresponding to the energy-saving cell and the detection signal sending period, and receives the detection signal sent by the terminal at the detection frequency band.
It should be noted that, the energy-saving cell may close the uplink channel in the symbol time except the sounding period, so as to reduce the power consumption of the base station.
S304, the energy-saving cell determines the wake-up time of the energy-saving cell according to the detection signal.
Specifically, if the energy-saving cell monitors that the detection signal power of the detection signal in the detection period is greater than the power threshold value in the monitoring period, the detection period is determined to be the target period. The monitoring period may be a preset period.
If the number of the target time periods monitored by the energy-saving cell in the monitoring period is larger than the number threshold, determining that the ending time of the monitoring period is the wake-up time of the energy-saving cell.
For example, if the power of the detection signal received by the energy-saving cell in a certain detection period is greater than a preset power threshold, the detection period is determined as a target period. If the number of the target time periods is larger than a preset value in a certain monitoring period, determining the ending time of the monitoring period as a wake-up time.
S305, the energy-saving cell enters a working state at the wake-up time and accesses the target terminal.
Illustratively, the energy-saving cell enters the operational state from the off state at the wake-up time. And the base station of the energy-saving cell starts an uplink channel and a downlink channel at the wake-up time, and normally receives and transmits signals so as to access the target terminal.
Further, if the target terminal is successfully accessed to the energy-saving cell, the terminal does not belong to the target terminal any more, the energy-saving cell can remove the terminal from the target terminal, and the terminal stops sending the detection signal to the energy-saving cell.
If a certain target terminal is not successfully accessed to a corresponding energy-saving cell, determining the terminal as the terminal which receives the access failure indication message in the target terminal, executing the steps S301-S304 provided by the embodiment of the application in the next monitoring period, re-determining a corresponding new energy-saving cell, sending a detection signal to the new energy-saving cell, and accessing the target terminal to the new energy-saving cell after the new energy-saving cell enters a working state.
According to the wake-up method of the energy-saving cell, the target terminal determines the energy-saving cell corresponding to the target terminal according to the cell information, then sends the detection signal to the energy-saving cell according to the target power, and after receiving the detection signal sent by the target terminal, the energy-saving cell determines the wake-up time of the energy-saving cell according to the detection signal, and then enters a working state at the wake-up time and is accessed into the target terminal. The application matches the wake-up time of the energy-saving cell with the actual service requirement of the energy-saving cell by utilizing the detection signal of the target terminal, thereby improving the accuracy of the wake-up time of the energy-saving cell, realizing the on-demand wake-up of the energy-saving cell and taking into account the energy-saving effect and the service performance.
