step S101: before the communication equipment loads the version program, judging whether energy-saving processing is needed or not;
in this step, the communication device may be a base station including a baseband processing unit BBU, or a base station protecting a radio remote unit RRU, or a base station including both the baseband processing unit BBU and the radio remote unit RRU, and the specific situation is determined according to the specific situation, and it should be understood that the communication device that needs to perform version program loading to implement version program loading of a corresponding service is included.
Step S102: and if the judgment result is needed, the communication equipment does not load the version program.
In this step, the communication device can be put in the state of lowest power consumption without loading the corresponding version program. It is worth noting that a transmission detection module is added in the BOOT of the communication device (BBU or RRU) including the BOOT module BOOT to determine whether transmission is normal, and the determination standard can refer to whether the optical module is inserted into the optical port, whether there is an optical signal, and whether the optical port power meets the requirement. For the power network port, it needs to judge whether the network port has a signal. For communication equipment which does not have an independent BOOT module or is inconvenient to process in the BOOT module, the transmission state is judged at the early stage of version loading, and if the transmission does not meet the communication requirement, the subsequent version is not loaded, and the unrelated core function is not started.
Specifically, in step S101, it is specifically determined whether or not the energy saving process is required, and it is possible to determine whether or not the communication link connected to the communication terminal is failed, and if so, it is determined that the energy saving process is required. Specifically, the determining, by the communication device, whether the communication link connected to the communication device fails includes: the communication device determines whether at least one of the following occurs: and no optical module is inserted, no optical signal exists, and the optical power is lower than a preset threshold and no electric port signal. It is noted that the preset threshold value can be specifically set according to specific situations. The method for determining whether the communication link is failed is not limited to the above method, and other methods for determining that the communication link is failed are all protected.
Specifically, in step S101, the communication device is a baseband processing unit including at least one baseband board; judging whether energy-saving processing is needed comprises: the baseband processing unit judges whether all cells of at least one radio remote unit corresponding to one baseband single board need to be closed, and if yes, the baseband processing unit judges that energy-saving processing is needed. It should be noted that, specifically, the determining whether the cell needs to be closed may be performed by determining whether a user of the cell meets a preset condition, and if so, removing the user of the cell and then closing the cell, or may be performed according to the service and coverage of the cell, which should be understood that existing methods capable of determining that the cell needs to be closed and performing energy saving processing are included.
Specifically, in step S101, the communication device is a baseband processing unit including at least one baseband board; further comprising: after the version program is normally loaded, the baseband processing unit judges whether all cells of at least one radio remote unit corresponding to one baseband single board need to be closed, and if so, deep energy-saving processing is performed. Specifically, the deep energy-saving processing includes: and resetting the radio frequency unit and closing a communication link connected with the radio frequency unit.
Further, for better energy saving, the method further comprises the following steps: and when the baseband processing unit judges that all the cells corresponding to the baseband single board need to be closed, the power supply to the baseband single board is stopped.
Further, for better control of communication equipment energy saving, complex control is avoided: and when the communication equipment judges that the communication link has a fault, the communication equipment closes the communication link between the communication equipment cascaded with the lower level of the communication equipment.

step S101: a base band processing unit (BBU) in a base station judges whether the optical power is lower than a preset threshold value;
step S102: and if the light power is judged to be lower than the preset threshold value, the version program of each device is not loaded, and the device is in a low-consumption state.
EXAMPLE III
In the energy saving method of the communication device of this embodiment, the communication device is taken as a base station of a baseband processing unit BBU and a radio remote unit RRU, and for example, as shown in fig. 3, the method includes the following steps:
step S301: a base band processing unit (BBU) in a base station judges whether the optical power is lower than a preset threshold value;
step S302: if the optical power is judged to be lower than the preset threshold value, the BBU does not load each device version program, and the device is in a low consumption state;
step S303: a baseband processing unit (BBU) closes a communication link connected with a Radio Remote Unit (RRU);
in this step, it should be understood that there is a cascade relationship between the baseband processing unit BBU and the radio remote unit RRU, that is, the radio remote unit RRU is a cascade communication device at the next stage of the baseband processing unit BBU.
Step S304: the RRU does not load each device version, and the device is in a low consumption state.
It should be noted that the remote radio module in this embodiment is loaded with a version program.
Example four

step S401: the BBU refers to the cell service information and the coverage information, determines a cell to be energy-saving according to a certain strategy, and switches off the cell;
step S402: the BBU searches an optical port corresponding to the energy-saving cell;
