IPC: H04W24/00
Filed: 2000-12-30
Abstract: PURPOSE: A method for automatically diagnosing a switching system is provided to collectively process MMCs requiring various repetitive performances through an automated tool. CONSTITUTION: An emulator reads an instruction code file for saving pattern information, instruction code, and procedure information(S101). The emulator executes a run thread routine(S102) and waits for signals from a run thread and an MMS(S103). It is determined whether the received signal is BatchMsgToClientSig(S104). It is determined whether the received signal from the run thread is a request for performing a command(S114). The emulator loads the command to BatchMsgToClientSig for transmitting to the MMS(Man-Machine Subsystem)(S115). It is checked whether the received signal is a run thread termination data(S116). A memory assigned to each part is released(S117). It is checked whether the received data is command-examining result(S105). The emulator performs operation corresponding to the command examining result(S106). It is determined whether the received data is message-outputting data(S107). Output messages are divided by token and PRN(Printout Reference Number) is extracted(S108). It is checked whether the extracted PRN exists in the pattern information area(S109). Data are extracted by using extracted information recorded in the pattern information(S110). A procedure ID is extracted and the standby run thread is activated(S111). It is checked whether message output is completed(S112). MMC transmission count is decreased(S113).

IPC: H04M3/42
Filed: 2001-02-27
Abstract: PURPOSE: A method for reducing voice discontinuance generated due to a rate re-negotiation sequence is provided to detect, record and store noises in a normal traffic state in picture communication and to output the stored noises, instead of silence, if a rate re-negotiation sequence is generated. CONSTITUTION: A microcomputer in a picture phone judges whether a rate re-negotiation sequence is generated. In case that the rate re-negotiation sequence is generated, the microcomputer outputs the voice stored in a noise buffer to the speaker. If the rate re-negotiation sequence is not generated, the microcomputer outputs voice data to the speaker. Then the microcomputer judges whether voice data exist. In case that voice data exist, the microcomputer initializes a temporary buffer. If no voice data exist, the microcomputer stores the voice data outputted to the speaker in the temporary buffer and increases the noise count. If it is judged that the increased noise count exceeds a preset time, the microcomputer moves the contents stored in the temporary buffer to the noise buffer.
