  • Header compression mechanism for transmitting RTP packets over wireless links
    Patent number: 8532106
    Abstract: A header compression method for a MAC protocol that combines contention-free and contention-based MAC protocols into a heterogeneous MAC protocol used for forwarding VoIP traffic in VoIP systems on wireless networks using multiple base stations that reduces packet overhead thus allowing for transmission of high bit-rate data to multiple users over wired and wireless means.
    Type: Grant

  • RTP voice packets for base station hand-off in mobile IP telephony
    Patent number: 8483129
    Abstract: In wireless networks where the goal is to support a large number of VOIP based cellular calls, large overhead headers in RTP voice packets are not acceptable. In wireless networks where multiple base stations are deployed, handsets may handoff from one base station to the other while in a voice call creating a large overhead. This disclosure describes an efficient way to extend a header compression algorithm and lower the overhead when the handset is in a voice call and hands off from one base station to another.
