The capacity base station provides a communication service for at least one terminal device based on an operation mode, a power saving transition mode and a power saving mode. And when the operation mode is in, the capacity base station judges whether to switch the capacity base station to the energy-saving transition mode based on the predicted load information corresponding to the capacity base station. When in the energy saving transition mode, the capacity base station hands over the communication service corresponding to the at least one terminal device to at least one neighboring base station. In response to completion of handover of the communication service of the at least one terminal device, the capacity base station switches to the power saving mode, wherein the capacity base station switched to the power saving mode suspends provision of the communication service.

Description

Capacity base station and management method thereof Technical Field The present disclosure relates to a capacity base station and a management method thereof, and more particularly, to an energy-saving capacity base station and a management method thereof. Background With the development of communication technology, mobile communication technology is applied to many services, and thus telecommunications operators support more frequency bands, larger bandwidth, more antennas, and denser networks to meet market demands. According to the research, the energy consumed by the mobile communication network is mainly used for maintaining the wireless network, and the energy consumption of the base station is the largest. Therefore, the energy saving of the base station is always the research focus in the field of energy saving of the mobile communication network. In the standard set by 3GPP, a capacity base station (capacity booster cell; CBC) can transfer (hand over) a User Equipment (UE) connected to other base stations when load is reduced, and switch to a power saving mode to reduce power consumption. On the other hand, a coverage base station (CC) is used to provide a wider signal coverage. When the load of the coverage base station becomes high, part of the communication service of the user equipment can be handed over to the capacity base station in the coverage area at proper time, so as to achieve the purpose of distributing the load. However, in the existing energy saving mode switching mechanism, there are problems that (1) when a capacity base station hands over its own traffic to other base stations and switches to an energy saving mode, causing overload of other base stations, the capacity base station still has to be activated again to share the overload traffic, causing the capacity base station to switch repeatedly, and (2) when two adjacent capacity base stations hand over user equipment to each other at the same time in preparation for entering the energy saving mode, neither can empty the load and switch to the energy saving mode. In view of this, there is a need in the art for an effort to avoid the above-mentioned collision situation, so that the capacity base station can be switched to the energy-saving mode. Disclosure of Invention In order to solve the above-mentioned problems, the present disclosure provides a capacity base station, which includes a communication interface and a processor. The communication interface is used for being in communication connection with a coverage base station. The processor is electrically connected with the communication interface. The capacity base station provides a communication service for at least one terminal device through the communication interface based on an operation mode, a power saving transition mode and a power saving mode. In response to the capacity base station being switched to the run mode, the processor determines whether to switch the capacity base station to the energy saving transition mode based on a predicted load information corresponding to the capacity base station. The processor performs an operation of handing over the communication service corresponding to the at least one terminal device to at least one neighboring base station including the overlay base station or a neighboring capacity base station corresponding to the capacity base station in response to the capacity base station being handed over to the power saving transition mode, and a operation of handing over the capacity base station to the power saving mode in response to the communication service of the at least one terminal device being handed over being completed, wherein the capacity base station handed over to the power saving mode suspends providing the communication service. In one embodiment of the present invention, the operation of determining whether to switch the capacity base station to the energy saving transition mode further comprises calculating the predicted load information of the capacity base station based on a historical load record of the capacity base station, and determining to switch the capacity base station to the energy saving transition mode in response to the predicted load information being below a first load threshold. In one embodiment of the present invention, the processor performs operations of broadcasting a first inhibit signal to at least one neighboring terminal device to suspend providing the communication service of the at least one neighboring terminal device in response to determining to switch the capacity base station to the power saving transition mode, transmitting a second inhibit signal to the neighboring base station to reject a handover request corresponding to the neighboring base station, returning a cancel handover signal to the neighboring base station in response to receiving the handover request from the neighboring base station, and switching the capacity base station to the power saving transition mode
