摘要

A base station, a terminal device, a control method, and a program for communication handover are provided. First information indicating one or more base stations which are candidates for a handover destination of a terminal device in connection from a base station, is acquired. Second information regarding communication quality predicted in a communication through a candidate base station for each of the candidate base stations is acquired based on the first information. Third information regarding the communication quality for at least one of the candidate base stations is notified to the terminal device based on the second information. The third information is used to handover of the terminal device.

說(shuō)明書

The terminal device may continuously execute (S507) the measurement of radio quality of the radio signals (S505, S506) transmitted from the surrounding base stations. Then, the terminal device transmits the measurement report (MR) capable of providing a handover trigger to the base station 1 based on the value of the measurement result and the information on the communication delay (S508). The base station 1 performs a process for executing a handover of the terminal device in response to receiving the MR (S509). For example, in response to receiving the MR including the information on the base station 2, the base station 1 transmits a handover request to the base station 2, and in response to obtaining the approval from the base station 2, transits an instruction message for switching the connection destination to the terminal device. This procedure is similar to a procedure used conventionally, and therefore will not be described in detail here.
