TECHNICAL FIELD The present application relates to the technical field of wireless communication, but is not limited to the technical field of wireless communication, in particular to a method for determining Extended Discontinuous Reception (eDRX) parameters, a communication device, and a storage medium. BACKGROUND 3GPP has introduced new power-saving mechanisms for Narrow Band Internet Of Things (NB IOT), which respectively are an Extended Discontinuous Reception (eDRX) mode, a Discontinuous Reception (DRX) mode and a Power Save Mode (PSM). As shown in FIG. 1, in each eDRX cycle, there is a Paging Time Window (PTW), and the user equipment (UE, User Equipment) monitors the paging channel in the PTW according to the DRX cycle, in order to receive downlink data, and the terminal is in a sleeping state in the rest of the time. Since the duration of the DRX cycle is short, it can be considered that the terminal is always reachable without sleeping. In the eDRX mode, it can be considered that the terminal device is reachable at any time, but the time delay is relatively large, and the time delay depends on the eDRX cycle, and a balance between low power consumption and time delay can be struck.
