Filed: 2000-12-23
Abstract: PURPOSE: A method for enhancing transmission speed using hop count in mobile computing environment is provided to use a hop count module to a reception function of a transmission protocol, thereby achieving a routing optimization at the optimum hop count. CONSTITUTION: A hop count for providing the optimum transmission capability according to a time of movement is set to a transmission control protocol of a mobile host(MH)(S10). Thereafter, position information of MH and data at a transmitter, as a Correspondent Host(CA), is transmitted to a home agent(HA)(S11). The HA receives the data, check the position of the MH and then discriminates whether the MH belongs to a charge region of HA(S12). If the MH belongs to a charge region of HA, the HA transmits data to the MH. The MH receives the data and discriminates whether the hop count is the same as a time of movement(S13). If the hop count is not the same as a time of movement, the MH transmits a response message to the received message to the HA(S14). The HA transmits the message to the CA(S15). The CA checks the message from the HA and confirms whether a conversion message exists via a route optimum method(S16). If the hop count is the same as a time of movement, the MH transmits a conversion message to the HA and a foreign agent(FA)(S17). The HA and FA transmit a response message to the CA(S18). If the conversion message is confirmed, the CA transmits data to the HA(S19). The data of CA is transmitted to the MH by the HA, the discrimination of sameness between the hop count and a time of movement is performed(S20). If it is discriminated that the position of MH do not belong to the charge region, the HA performs a tunneling to the FA. Thereafter, the FA transmits the data received from the CA to MH(S21).

Title: Method of Echo Removing by Vocoder Variable Data Rate
Inventor: JUNG WON GUK
IPC: H04W24/02
Filed: 2000-12-28
Abstract: PURPOSE: A method of removing an echo using a vocoder variable information rate is provided to operate an adaptive echo remover without changing a filter coefficient when a present frame is decided to a nonvoice section, thereby increasing stability of the adaptive echo remover. CONSTITUTION: A variable rate vocoder compresses a voice signal at several rates, and inputs the signal to a simultaneous call detector and an adaptive filter updater(30). The simultaneous call detector decides whether a compressed present frame is below a 1/8 rate, and if so, the simultaneous call detector recognizes a state as a simultaneous speech state. If the present frame is over the 1/8 rate, the simultaneous call detector does not recognize the state as the simultaneous speech state and updates an adaptive filter coefficient to operate an adaptive echo remover(32, 34). If the state is the simultaneous call state, the simultaneous call detector does not update the adaptive filter coefficient, and operates the adaptive echo remover by applying a present coefficient(33).
