    Abstract: PROBLEM TO BE SOLVED: To enable efficient operation of channel resources by excluding the non-efficient utilization of the channel resources by autonomously reporting system data from a remote site and allocating a transmission parameter through a local controller while using this information. SOLUTION: The remote site of mobile equipment 106 autonomously supplies the system data such as the measured value of a received signal strength, for example, through a base station transceiver 104 to a base station controller 102 during a period in which a communication link is settled active. Thus, the reduction of setting overhead is achieved. By using the autonomous report of the measured reception strength, the base station controller 102 can control burst transmission parameter allocated before each of burst transmission such as data velocity, band width and nominal initial output power, for example. Further, on the basis of this autonomous report of the received signal strength, in the case of burst transmission, the base station controller 102 can control energy from the base station controller 102.

    Abstract: PROBLEM TO BE SOLVED: To avoid the wasteful use of the channel resource of a communication system by minimizing the number of occurring times of time-outs. SOLUTION: In a method for controlling time-out of communication protocol, the length of the time-out is decided, based on the sum of an average channel delay and the quadruple of the deviation of a channel delay. When the deviation of the channel delay is increased by introducing a delay to a communication channel, the time required for the time-out becomes longer. Consequently, the channel resource of the communication system can be utilized effectively, because the length of the time-out dramatically decreases and wasteful ramp up times become shorter.

    Abstract: PROBLEM TO BE SOLVED: To improve the transmission rate allocation efficiency of a wireless system by selecting a data rate sufficient for the support of the data rate of a communication link which is measured from data rate mode for a given user. SOLUTION: Management/control functions are supplied to the component of a wireless network. A mobile switch center(MSC) 100 supplies an interface between the wireless network and a cable network (PSTN) 110 or with a different wireless network (MSC) 120. A base station controller(BSC) 102 supplies the control and management functions to a base transceiver station(BTS) 104. The data rate of transmission on a communication link to a given user is measured on the basis of the measurement value of data in a data buffer. A data rate sufficient for supporting the data rate of the communication link, which is measured from a plurality of data rate modes, is selected to the given user.

    Abstract: A method is described to reduce the time required to assign the burst transmission parameters in a wireless communication system by autonomously sharing transmission and reception information among the components of the network. Information is autonomously provided from a remote subnetwork element to a controlling network element so the controlling network element may use the information to dynamically assign and update burst transmission parameters.

    Abstract: The Radio Link Protocol framing system provides the mobile wireless station set with high speed data transmission capability by using the Dedicated Control Channel, which comprises a stream of 20 msec frames, to carry a single 18 byte Radio Link Protocol frame and the Supplementary Channel, which comprises a stream of 20msec frames, to carry many 18 byte Radio Link Protocol frames to accommodate high-speed bursts of data. The Radio Link Protocol framing system packs the Radio Link Protocor frames within the Supplementary Channel (SCH-RLP frames) to maximize the data processing efficiency. The Radio Link Protocol framing system functions to package the subscriber's data into predetermined frame format consisting of Core Units, which are packed, as needed, into one SCH-RLP frame. The data capacity is limited solely by the Supplementary Channel burst capacity. By simply computing the Cyclic Redundancy Check bits to validate the accuracy of the data contained within a SCH-RLP frame enables the system to copy the data directly from the SCH-RLP frame to data receive buffers. Both sequential and non-sequential frames can be incorporated into a single SCH-RLP frame. The Core Unit is the common divisor of both the Dedicated Control Channel and the Supplementary Channel. The Dedicated Control Channel supports transmission of a full frame of 9.6Kbps, while the Supplementary Channel supports data transmission speeds of 9.6Kbps and higher.
