A Low Power Node (LPN) may be called a small base station, and there are usually two deployment scenarios of hot spot deployment and enhanced coverage; in a hot spot deployment scenario, in order to achieve a high data rate and spectral efficiency, a large number of small base stations need to be densely deployed in an area, but due to a small coverage area of a small cell (small cell) under a small base station, the probability of handover failure occurring when a medium-high speed mobile User Equipment (UE) passes through a small base station is increased, and the service continuity of the UE is affected. In order to improve the UE mobility after introducing a small cell, it is proposed in the industry that a base station, such as a macro base station, ensures basic coverage, the UE always maintains Radio Resource Control (RRC) connection with the base station, and the small cell is only used as a transmission node to provide a higher data rate.
Under the system architecture, a UE maintains connection with at least two base stations and uses radio resources under the two base stations, so as to implement cross-node radio resource aggregation, where the architecture is generally called a dual-connection architecture, as shown in fig. 1, of the two base stations to which the UE is connected, one of the two base stations having certain management and control capabilities is generally called a Master base station (MeNB, Master eNB), and the other base station is called a Secondary base station (SeNB, Secondary eNB); to support higher throughput or better mobility, the dual connectivity architecture may be extended to a multi-connectivity architecture in which a UE may communicate with multiple wireless access points or base stations of more than one wireless access system or network.
Under a dual-connection or multi-connection architecture, the longer the sleep time of the UE in a certain base station is, the more power can be saved, however, if the UE sleeps in a certain base station for a long time, when new service data or signaling arrives in the sleep time, if the UE cannot be awakened in time, the service experience of the user may be affected.
