  • Method and apparatus for creating a packet using a digital signal processor
    Patent number: 7088739
    Abstract: The present invention provides a method and apparatus for creating a packet using a digital signal processor. Call set-up information is received. Thereafter, call data is received and a data portion of the packet is created using the call data. One or more headers are created using the call data and the call set-up information. The packet is then created by attaching the one or more headers to the data portion of the packet. In addition, the one or more headers may include a real time transport protocol header, a user datagram protocol header, an Internet protocol header, and a media access control header.

  • Method and apparatus for compressing packet headers
    Patent number: 6954460
    Abstract: The present invention provides a method and apparatus for creating a packet having one or more compressed headers. Call set-up information is received. Thereafter, call data is received and a data portion of the packet is created using the call data. One or more current headers are created using the call data and the call set-up information. The one or more current headers are compressed. The packet is then created by attaching the one or more compressed headers to the data portion of the packet. The one or more compressed headers are created using one or more differences between the one or more current headers and the one or more previous headers. After compression, the one or more current headers are saved as the one or more previous headers.
