Abstract: This disclosure relates to collaborative optimization of random access channel configuration in wireless access networks. In one implementation, optimization of the random access channel configuration in one wireless access network node may be performed with assistance from other wireless network nodes by receiving operational parameters that may be relevant for random access channel configuration optimization but are not locally collected at the wireless access network node.

Abstract: Provided are a handover evaluation and report method, apparatus and a base station. A source base station sends a beam measurement indication, a cell measurement strategy and a threshold of one of RSRP, RSRQ, or SINR to a target base station. The target base station instructs the terminal to measure a cell on a source base station side according to the beam measurement indication and the cell measurement strategy. In response to determining that an inter-system handover of the terminal is an unnecessary handover according to a cell measurement result sent by the terminal, the target base station generates an inter-system handover report indicating that this handover of the terminal is the unnecessary handover and sends the inter-system handover report to the source base station Thus, the source base station acknowledges, according to the inter-system handover report, an unnecessary inter-system handover is performed by the terminal.
