Abstract

A communications apparatus includes an RF signal processing device, a baseband signal processing device and a processor. The processor controls operations of the RF signal processing device and the baseband signal processing device, camps on a first cell of a first RAT, collects cell selection/reselection parameters of one or more frequencies of the first RAT in an autonomous fast return (AFR) list, switches from the first RAT to the second RAT to camp on a second cell of the second RAT, establishes a connection with a peer communications apparatus via the second cell, receives a connection release message or a channel release message from the second cell to release the connection, and switches from the second RAT to the first RAT by performing a cell selection procedure or a redirection procedure according to the AFR list to camp on a third cell of the first RAT.
