1. A wireless communication apparatus comprising:
- a wireless communication unit for performing wireless communication by connecting to a first wireless communication network and a second wireless communication network different from the first wireless communication network;
an execution unit for executing an application for real-time communication via the wireless communication unit;
a communication quality obtaining unit for obtaining communication quality of a wireless link of the first wireless communication network during execution of the application by connecting to the first wireless communication network;
a determination unit for determining whether to start preparing handover from the first wireless communication network to the second wireless communication network based on the communication quality obtained by the communication quality obtaining unit;
an estimation unit, when the determination unit determines to start preparing handover during execution of the application, for estimating a handover start time based on the communication quality obtained by the communication quality obtaining unit; and
a control unit for controlling so as to notify that the handover is in progress, during processing of the handover.

Abstract
There is a problem that, if a silent period is generated to a real-time application such as VoIP due to handover using BBM method, a user has a sense of anxiety and misunderstands that communication is completely disconnected. If the silent period is generated to the real-time application such as VoIP due to packet loss at handover, a terminal activates handover alarm (beep sound, for example), indicating that handover is in progress, during the silent period. Thereby, it notifies the user that the silent period is caused by handover and prevents user'"'"'s misunderstanding that communication is completely disconnected.

7. A communication apparatus comprising:
-
a communication unit for executing communication by connecting to a communication network; an execution unit for executing an application for real-time communication via the communication unit; and a control unit for controlling so as to receive handover information, from a wireless communication apparatus, that the wireless communication apparatus, which is a communication counterpart of the application, performs handover from a first wireless communication network being communicated to a second wireless communication network different from the first wireless communication network and to notify that the handover is in progress during processing of the handover. - View Dependent Claims (8, 9, 10, 19, 20)
