Abstract
A radio communication apparatus includes a first access unit and a second access unit. The first access unit accesses a first radio network. The second access unit accesses a second radio network that performs higher-speed communication than the first radio network. When a packet connection request is made while the radio communication apparatus is in a service area of the first radio network, the second access unit accesses the second radio network, and attempts to make a connection to the second radio network.

4. A radio communication method, wherein
when a voice call origination request is made while a radio communication apparatus is connected to a second radio network that performs higher-speed communication than a first radio network, the radio communication apparatus accesses the first radio network, and makes a voice call through circuit switching of the first radio network, and wherein when a packet connection request is made after the voice call is disconnected, the radio communication apparatus holds the packet connection request to the first radio network, and forcibly accesses the second radio network.
