发明名称 IMPROVED QUALITY OF VoIP MEDIA DATA FLOW BY ADAPTATION OF VOICE CODING BASED ON SELECTED MODULATION AND CODING SCHEME (MCS)
摘要 FIELD: information technologies. ^ SUBSTANCE: connection of voice transfer over IP (VoIP) is established through radio interface with mobile radio station. Current conditions of radio communication are determined for VoIP connection, and based on this, modulation and coding scheme (MCS) for part of VoIP connection. Mode of VoIP coding is selected for part of VoIP connection, based on a certain modulation and coding scheme. VoIP voice is then coded into certain quantity of coded VoIP frames, using selected mode of VoIP coding, which has an associated bitrate. Optimal quantity of coded VoIP frames is included into VoIP packet for transportation through VoIP connection at selected mode of voice coding and selected MCS. ^ EFFECT: error resistance and maximisation of VoIP communication capacity. ^ 28 cl, 10 dwg, 4 tbl
