Communication interface and method for robust header compression of data flows
First Claim
Patent Images
1. A communication interface, comprising:
- a processor configured to generate data for a data flow having packets and associated with a context ID (CID) and a data flow status indicator, and provide a robust header compression (RoHC) compressor that employs said CID to compress headers of said packets and marks said CID as reusable by another data flow if said data flow status indicator indicates said data flow is terminated; and
a transmitter configured to transmit said packets.

Abstract
A communication interface and method for efficient robust header compression (RoHC). One embodiment of the communication interface includes: (1) a data flow associated with a context ID (CID) and a data flow status indicator, and having packets, and (2) a robust header compression (RoHC) compressor configured to employ the CID to compress headers of the packets and to mark the CID as reusable by another data flow if the data flow status indicator indicates the data flow is terminated.

8. A method of robust header compression (RoHC), comprising:
-
employing a context ID (CID) to compress packet headers of a data flow; gaining access to a data flow status indicator; and marking said CID as reusable if said data flow status indicator indicates said data flow is terminated, wherein said employing, said gaining and said marking are performed by a processor. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A modem, comprising:
-
a modem processor configured to provide a protocol stack that is operable to receive packets of a data flow, said packets having respective headers; a robust header compression (RoHC) compressor that is operable to; employ a context ID (CID) to compress said respective headers, determine if said data flow is terminated based on a data flow status indicator associated with said data flow, and mark said CID as reusable by another data flow if said data flow is terminated; and a transmitter configured to transmit said packets. - View Dependent Claims (16, 17, 18, 19, 20, 21)
