Patent ID: 8614991

Claim:
A wireless communication apparatus comprising: a wireless communication unit configured to perform 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 configured to execute an application for real-time communication via the wireless communication unit; a communication quality obtaining unit configured to obtain 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 configured to determine 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, configured to estimate a handover start time based on the communication quality obtained by the communication quality obtaining unit; a control unit configured to control so as to generate a sound indicating that the handover is in progress, during processing of the handover; and a determination unit configured to determine whether a user of the wireless communication apparatus is a speaker or a hearer in the application, wherein the control unit is configured to control a time to generate the sound indicating that the handover is in progress, based on a result of determination by the determination unit, and wherein the control unit, based on the result of determination by the determination unit: is configured to generate the sound indicating that the handover is in progress immediately after start of handover if the user is a speaker, and is configured to generate the sound indicating that the handover is in progress when there is no reproduction data of the application after start of handover if the user is a hearer.
