Patent ID: 8351344

Claim:
A system for measurement of Voice over Internet Protocol (VoIP) Quality of Experience (QoE), comprising: a QoE analysis unit that receives and analyzes first quality measurement information collected through a predetermined measurement method and second quality measurement information collected through a terminal with respect to voice quality, wherein the terminal includes a customer QoE measurement module wherein measurement of customer QoE is initiated by a request signal inputted from the outside, displays a first message indicating that the customer QoE for presently calling voice quality is being measured when the measurement of customer QoE is initiated, a second message for inducing the customer QoE measurement when the QoE analysis unit has collected the first quality measurement information, and a third message indicating that the customer QoE measurement is received when the QoE analysis unit has received the customer QoE measurement; a subscriber management unit that performs subscriber management for after-treatment on the basis of analysis in the QoE analysis unit; and an opening/cancelling management unit that collects data to be used for analysis of the second quality measurement information in the QoE analysis unit, wherein the first quality measurement information includes a one-way delay value for a first packet inputted through a session for measuring voice quality, wherein the one-way delay value is for a sender report packet, wherein the one-way delay value is an average one-way transmission delay value based on transmission delay for all received first packets when a one-way transmission delay time on the basis of a time stamp of the first packet inputted through the session for measuring voice quality exceeds a predetermined delay time.
