The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
When the distributed base station is actually deployed, the surrounding base stations may support low-power-consumption operation and wake-up notification functions, and may not have the low-power-consumption operation and wake-up notification functions.
When the surrounding base stations do not have the low power consumption operation and wake-up functions, and when the distributed base stations are actually deployed, the remote units overlapping with the base stations without the low power consumption operation and wake-up functions can be set not to enter the low power consumption, and the energy-saving function of operating and waking up the remote units with the low power consumption can also be provided, and the method is shown in fig. 1:

When the external base station does not support low power consumption and awakening function, the remote unit with mobile interaction between the distributed base station and the external base station is set not to enter low power consumption, and other remote units can enter low power consumption. When the terminal moves between the external base station and the distributed base station in a connection state or a non-connection state, the remote unit without entering low power consumption guarantees the moving continuity of the network service. When the terminal moves among the remote units of the distributed base station, the method ensures to wake up and operate the remote units with low power consumption, saves energy and simultaneously ensures the continuity of service.
In specific implementation, the remote units which do not enter the low power consumption state can be allowed to enter the low power consumption state according to a certain strategy, so that the energy is further saved.
When the surrounding base stations have low power consumption and wake-up functions, the distributed base stations provide energy saving functions together with the surrounding base stations, including embodiment 2 and embodiment 3:
referring to fig. 2, the method for saving energy of a distributed base station of the present invention includes the following steps:
201: the near-end unit of the distributed base station detects the service under each far-end unit in real time, counts the service condition of each far-end unit,
202: determining if there is a terminal under the remote unit, if there is no terminal, executing 203, otherwise executing 205,

205: if there is a terminal, it is determined whether there is a traffic problem with the remote unit, and if so, execution 206,
206: if the service problem exists, if the remote unit has a neighboring remote unit in a low power consumption state, a notification message is sent to the neighboring remote unit, the neighboring remote unit in the low power consumption state is awakened, the awakened remote unit is recorded to be in a normal state, if the awakened neighboring remote unit has a neighboring base station, and all the remote units related to the neighboring base station are in a normal working state, the neighboring base station is notified, and the distributed base station enters a normal working state.
In embodiment 1 and embodiment 2, the set energy saving conditions include whether the set time point is a time point at which the low power consumption state can be performed, and whether the remote unit is allowed to perform the low power consumption state.
Specifically, in embodiment 1 and embodiment 2, the determining whether there is a terminal under the remote unit includes the following steps:
the remote unit checks whether a connection state terminal exists, and the base station knows the condition of the connection state terminal in real time and can directly obtain the condition;
and for the remote unit without the connected terminal, detecting whether a non-connected terminal exists, setting a first timer, starting the first timer when the remote unit is judged to have no terminal, and judging that the remote unit has no terminal when the remote unit has no terminal in the timing period of the first timer.

the remote unit judges whether the system message has the specific reporting parameter corresponding to the remote unit, if not, the public system message is broadcasted, otherwise, the specific system message of the remote unit is broadcasted.
Because the remote unit needs to be powered off, it needs to detect whether there is a terminal under the remote unit.
Whether the remote unit has a non-connection state terminal or not is detected, and a detection threshold needs to be sent to the terminal through a system message.
For a distributed base station system, the near-end unit is the entire control center, and the system messages sent by the near-end unit to all the far-end units are generally the same.
For example, all remote units have connected terminals, the near end unit broadcasts common system messages, and all remote units broadcast common system messages.
At a certain moment, the near-end unit detects that a certain far-end unit has no connected terminal, at this moment, other far-end units all have connected terminals, and other far-end units do not need to perform non-connected terminal detection, so that the near-end unit issues a system message for detecting whether a terminal exists or not for the far-end unit without the connected terminal, and other far-end units with the terminal do not need to detect.
At this time, the near-end unit simultaneously issues a public broadcasting system message and a specific system message of the far-end unit, wherein the messages comprise the report parameters for detecting the non-connected terminal.
The remote unit broadcasts a specific system message to detect the non-connection state terminal; other remote units broadcast the common system message without detecting the unconnected terminal.
The remote unit of the distributed base station can independently broadcast a specific system message, which is a method for realizing whether the remote unit independently detects a non-connection state terminal, so that whether the remote unit can enter a dormant state or not can be realized.
In embodiment 1 and embodiment 2, the determination of whether the remote unit has a service problem includes a terminal mobility problem and a traffic amount higher than a set threshold.
Specifically, the following is performed for determining whether there is a terminal mobility problem: and setting a second timer, starting the second timer when the terminal mobility problem is detected, and judging that the terminal mobility problem exists if the terminal mobility problem exists in the timing period of the second timer.
Specifically, the detecting of the terminal mobility problem includes that for the connected terminal, the remote unit checks whether the connected terminal has the terminal mobility problem, and the base station knows the condition of the connected terminal in real time and can directly obtain the condition;
for the non-connection state terminal, setting a second configuration parameter of the information reported by the non-connection state terminal, wherein the second configuration parameter is used for detecting whether the remote unit has the mobility problem of the non-connection state terminal,
the near-end unit generates a system message and broadcasts the system message, wherein the system message comprises a second configuration parameter of the set non-connection state terminal reporting information,
the terminal receives the system message broadcast by the near-end unit, stores the second configuration parameter,
the non-connected terminal judges whether the reporting threshold is met according to the second configuration parameter,
if the non-connected terminal meets the report threshold, the information is reported to the remote unit,
if the remote unit receives the information reported by the non-connection state terminal, it judges that there is a mobility problem of the non-connection state terminal,
the second configuration parameter comprises duration and a threshold lower than a terminal reselection threshold, and if the quality of the current service cell of the non-connected terminal is lower than the threshold in the second configuration parameter in the duration, the reporting threshold is judged to be met.
The specific steps for the base station traffic higher than the set threshold include: and setting a third timer, starting the third timer when the traffic of the base station is judged to be higher than the set threshold currently, and judging that the traffic of the base station is higher than the set threshold when the traffic of the base station is higher than the set threshold in the timing period of the third timer.
Corresponding to the method of embodiment 2, the present invention also provides embodiment 3:
referring to fig. 3, the method for saving energy of a distributed base station of the present invention includes the following steps:
301: the near end unit receives the notification message as in embodiment 2 sent by the neighboring base station,
302: judging whether the notification message notifies to awaken the current distributed base station or not;
303: if the notification message is to notify and awaken the current distributed base station, if the near-end unit is in the low power consumption state, the near-end unit is awakened and enters the normal working state, the near-end unit searches for the far-end unit which has the adjacent cell relation with the source cell of the base station sending the notification message, and awakens the far-end unit, records that the awakened far-end unit is in the normal working state,
for the awakened remote unit, detecting whether a terminal enters or not, if no terminal enters, the target remote unit enters a low power consumption state again, and if the remote unit has other adjacent base stations and all remote units related to the adjacent base stations are in a normal working state, informing the adjacent base stations that the distributed base stations enter the normal working state;
and 305, if the notification information is the working state of the neighbor cell base station, updating and storing the state information of the neighbor cell base station by the distributed base station.
In embodiment 3, detecting whether a terminal enters specifically includes the following steps: and setting a fourth timer, starting the fourth timer, detecting whether a terminal exists under the remote unit, if so, judging that the terminal enters, if not, judging that no terminal exists under the base station in the timing period of the fourth timer, otherwise, re-detecting whether the terminal exists under the remote unit.

and if the remote unit receives the reported information of the non-connection state terminal, judging whether the non-connection state terminal exists under the remote unit.
When the external base station supports low power operation and wake-up functions, all remote units of the distributed base station can enter a low power state. If the distributed base station is in a low power consumption state, when the terminal enters the distributed base station from an external cell, the external cell triggers a mobility problem to wake up the distributed base station, and the distributed base station wakes up a remote unit having a neighboring cell relation with the external cell to ensure the mobility of the network service of the terminal.
