Title: Method for managing state of trunk between our station and other station in digital mobile communication system
Inventor: KANG JEONG SUK
IPC: H04W84/08
Filed: 2000-03-30
Abstract: PURPOSE: A method for managing the status of an inter-office trunk line in a digital mobile switching system is provided to process an alarm supplied to an inter-office trunk line in real time and to increase the efficiency of processor resources by driving a periodical polling thread to process trunk line status only in case that an interrupt is activated as an event is generated. CONSTITUTION: In case that an alarm is supplied to a received frame, a control part activates an interrupt(ST11). The control part checks whether another polling thread is being executed by the previous interrupt(ST12). If another polling thread is not being executed, the control part checks whether information for the current interrupt is recorded in an interrupt status register(ST13). In case that information for the current interrupt is recorded in the interrupt status register, the control part compares the present value of the interrupt status register with its previous value(ST14). In case that a change exists between the two values, the control part drives a polling thread(ST15). The control part creates a polling timer so that this polling thread can execute polling periodically(ST16). The polling thread reports the status of the activated alarm to an upper resource management part(ST17). After cancelling the polling timer, the control part confirms whether the alarm is in a clear state(ST19). In case that the alarm is in the clear state, the control part removes the interrupt(ST20).

Title: Method and apparatus for link adaptation in mobile communication system

Filed: 2000-06-27
Abstract: PURPOSE: A link adaptation method and apparatus of a mobile communication system are provided to reduce an interference to a different sector and increase a forward system capacity by reducing a surplus transmission power, and to effectively use a power by controlling the power by continuously feedbacking a channel state of a forward link and be adaptive to the channel state. CONSTITUTION: A terminal(AT) measures a receiving C/I value for a forward pilot channel(S110), and searches the greatest value of critical values smaller than the measured receiving C/I value from a C/I table and makes it as a reference C/I value(S120). The terminal selects a data transfer rate corresponding to the reference C/I value from the C/I table as a receivable data transfer rate and makes the selected data transfer rate as a DRC symbol of 4 bits(S130). The terminal obtains a value by subtracting the reference C/I value from the receiving C/I value and makes it as a receiving C/I margin(S140). The terminal divides the receiving C/I margin into 16 levels and makes 4 bit C/I margin symbol, codes it like the 4 bit DRC symbol and transmits it to a base station(S150). The base station receives the DRC and the C/I margin system, decodes them, and transmits the decoded DRC to a scheduler of the base station and transmits the decoded C/I margin to a transmission amplifier of the base station(S160). The scheduler of the base station determines a terminal to be assigned a traffic channel of the next channel from the DRC and a data transfer rate of the terminal(S170). In transmitting a level of power to be transmitted to the determined terminal by the transmission amplifier of the station, a value obtained by reducing as much as the received C/I margin from a maximum power is determined as a transmission power level of the forward traffic channel(S180).
