摘要： A method and system for selective silencing in a WLAN mesh network are provided. In the selective silencing method, a node being silenced is distinguished from a node being activated. The mechanism for selectively silencing is activated by altering the setting of a bit (or bits) in the frame control field of the control frame. A control frame, including the bits with the pre-specified setting, is sent, with a destination set to a transmitter of the control frame.

摘要： A non-agile channelization method for multichannel medium access control (MAC) is provided, in which an available channel is categorized as an agile or non-agile channel, an operation mode of the channel categorized as the non-agile channel is selected, and multichannel switching is performed according to the selected operation mode.

摘要： A system and method for controlling congestion using Request-to-Send (RTS) and Clear-to-Send (CTS) in a wireless mesh network are provided. A receiver in a congestion state sets a duration field value of congestion control in a CTS frame and transmits the CTS frame to a sender. In response, the sender retransmits an RTS frame to the receiver without transmitting data, after waiting for an RTS retransmission waiting time period corresponding to the duration field value. The congestion state information is broadcast to neighboring nodes. Therefore, the congestion control system using the CTS frame does not use a separate frame for the congestion control. And, all of the neighboring nodes can participate in the congestion control, increasing the network efficiency.

摘要： In a harmonic speech encoder (16) a speech signal to be encoded is represented by a plurality of LPC parameters which are determined by a LPC parameter computer (30), a pitch value and a gain value. The speech encoder comprises a (coarse) pitch estimator (38) for determining a coarse pitch, and a refined pitch computer (32) to determine a refined pitch from the coarse pitch value. The refined pitch value is determined in an analysis by synthesis way, in which a refined pitch value is selected which results in a minimum error measure between a representation of a synthesized speech signal and a representation of the original speech signal.

摘要： Combinational networks may provide simultaneous connectivity over networks of different network types between user equipment. A communication session, comprising a circuit switched call and one or more packet switched sessions, may be deployed simultaneously over different network types, in relation to the same user equipment. The circuit switched call and the packet switched session can be correlated, in which case the communication session is regarded as a combinational session. By introducing a number of logical databases that contain actual data on network addresses and communication sessions, a correlation check is deployed applied by a correlation node. The check consists of a number of queries towards said databases or to other network entities, yielding whether the communication session is to be regarded as combinational. The result of the check may e.g. be deployed in an on-line combinational charging system.
