Abstract: Methods, systems, and devices are disclosed for wireless communication over unlicensed spectrum using a femto cell. In an implementation of the system, a dualmode mobile device adapted to communicate over a licensed frequency spectrum and over an unlicensed frequency spectrum is provided. The dual-mode mobile device detects the presence of a femto cell communicating over an unlicensed spectrum and in response, initiates a communication connection with the unlicensed spectrum femto cell. Subsequently, the connection over a license spectrum may be disconnected upon successful establishment of the connection over the unlicensed spectrum. In yet another implementation, a femto cell communicating over an unlicensed spectrum may be adapted to communicate with a mobile switching center and/or with a voice over IP switch.

Abstract: In a Voice over Internet Protocol (VoIP) video communication method and apparatus, first and second VoIP-based terminals store video event indexes and images mapped thereto with respect to state information of a user and terminal, and establish a session using session establishment information defining the video event. The first terminal then transmits a data packet including the video event index, and the second terminal receives the data packet and outputs an image mapped to the video event index of the images stored in advance. Thus, by transmitting and receiving a predefined index alone without transmitting user and terminal states as a real time data-type image, the VoIP video communication method and apparatus prevent unnecessary waste of bandwidth in video communication.

Abstract: In one embodiment, a voicemail system stores a voicemail message left by a first caller for a second caller. The voicemail system facilitates the transfer of a call out of a playback of the voicemail to the first caller and generates a credential that is coupled with the call. If the first caller is not available for the call, the second caller is transferred to the voicemail mailbox of the first caller where second caller records a second voicemail, which is placed in the mailbox of the first caller. The call may be transferred back to the mailbox of the first caller in response to a transfer code entered by the second caller. The voicemail system verifies the second caller based on the credential and returns the second caller to the appropriate location in the queue of voicemails.

Abstract: A reception-process manager of a call server writes, in a transfer-voice-data storage, voice data contained in a voice packet received from the transmitter terminal which has acquired the talk right. A transmission-process manager of the call server determines the next transmission interval of a voice packet for each receiver terminal on the basis of determination information received from the each receiver terminal. The transmission-process manager reads out the voice data in a size dependent on the determined transmission interval from the transfer-voice-data storage, generates voice packet containing the voice data for the each receiver terminal, and transmits the voice packet to the each receiver terminal. Thus, the voice-packet transmission interval can be changed for each receiver terminal without stopping voice-packet transmission.
