Abstract: Stored in an each speaker's sound volume coefficient table 13 are a speaker identification ID and information of a voice coefficient so as to be correlated with each other. A speaker identification unit 11 extracts an each speaker's ID from a received packet based on floor control information or outputs the packet as an RTP packet to an RTP buffer. A sound volume control unit 12 executes a control program 14a of a recording medium 14 to record a current speaker identification ID and reads a sound volume coefficient relevant to the speaker identification ID from the each speaker's sound volume coefficient table 13 to output the coefficient as sound volume control information. In this case, the sound volume control unit 12 increments/decrements the relevant sound volume coefficient based on sound volume adjustment information of a sound volume adjustment unit.

Abstract: A method (100) and system (20) for multiparty communication using at least one dual mode communication device includes a dual mode radio (11) having at least a first modem (12) for operation on a first network and a second modem (13) for operation on a second network and a processor (55) coupled to the radio. The dual mode radio can be programmed to establish (102) an interconnect call on a first network between the dual mode radio and a second communication device, receive (104) a request for a private call on a second network from a third communication device, and mix and route (106) audio from the private call and the interconnect call at the dual mode radio when a multiparty call mode is selectively chosen. The dual mode radio can be a first modem operating on a CDMA network and a second modem operating on an iDEN network.

Abstract: To conserve energy, components in mobile devices have to transition less frequently between “active” and “sleep” modes, and to sleep for longer intervals. In accordance with at least one preferred embodiment of the present invention, there is broadly contemplated herein an approach for remote discovery of wireless client and access point configurations, especially those settings associated with the power consumption of the client's wireless interface. Methods contemplated in the preferred embodiment use packet probing techniques to determine the client and access point configurations remotely. The probing techniques include sending packets to the client device, over the wireless LAN, at intervals calculated using data publicly available on the wireless LAN technology in use and results of previous packet probing measurements. Measurements from several packet probes and methods for statistical data processing are used to make a determination.

Abstract: An adjustment of the target signal to interference ratio (SIRtarget) at the start of each transmission (N) uses an Outage-Based OLPC method, which establishes the ratio (SIRtarget) as the sum of a first component (SIRoutage-tgt) that adjusts quickly to the conditions of the communications channel and a second component (SIRBLER-tgt) that is adjustable according to a target block error rate (BLERtarget) The stored values of the two components (SIRoutage-tgt, SIRBLER-tgt) in at least one prior transmission (N?1) are used obtain convergence of the target ratio (SIRtarget) by setting the initial value in the transmission (N) for the first component (SIRoutage-tgt) equal to a value higher than the average values for the first component (SIRoutage-tgt) and setting the initial value in said transmission (N) for the second component (SIRBLER-tgt) and setting the initial value in said transmission (N) for the second component (SIRBLER-tgt) equal to the average of the values of the second component (SIRBLER-tgt).

Abstract: A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay-sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay-sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.

Abstract: In an on-vehicle radio communication apparatus, when the battery is in a voltage discharging state, every time a predetermined period pases, a current consumption value is updated for the radio circuit by integrating the current consumption for steady operation of the radio circuit. In addition, every time an event occurs in the radio circuit, the current consumption value is updated for the radio circuit by integrating the current consumption for the event operation. If the current consumption value is greater than or equal to a predetermined threshold value, the operation is stopped.
