RADIO CONTROL APPARATUS, CONNECTION DESTINATION SWITCHING METHOD, AND SYSTEM

摘要

A radio control apparatus determines a call type of a communication terminal, and transmits a release redirection control signal to the communication terminal. When the call type is a general call, the release redirection signal not including broadcast information is transmitted to the communication terminal. When the call type is an important communication call, the release redirection control signal including the broadcast information is transmitted to the communication terminal.

主权项

1. A radio control apparatus configured to control radio communication of a communication terminal in a first radio communication system, the radio control apparatus comprising:
a determination unit configured to determine a call type of a communication of the communication terminal when a connection destination of the communication terminal is switched to a second radio communication system; a storing unit configured to repeatedly receive and store broadcast information, wherein the broadcast information is transmitted in the second radio communication system; and a communication unit configured to transmit a release redirection control signal to the communication terminal, wherein the release redirection control signal indicates that a connection with the first radio communication system is to be disconnected, and that a connection with the second radio communication system is to be established; wherein, when the call type determined by the determination unit is a general call, the communication unit transmits the release redirection control signal not including the broadcast information to the communication terminal, and wherein, when the call type determined by the determination unit is an important communication call, the communication unit transmits the release redirection control signal including the broadcast information to the communication terminal.
