RObust Header Compression (ROHC): Framework and four profiles: RTP, UDP, ESP, and uncompressed
TLDR
A highly robust and efficient header compression scheme for RTP/UDP/IP, UDP/IP and ESP/IP headers is specified in this document, done in a framework designed to be extensible.
Evaluation of CRTP performance over cellular radio links
TLDR
It is found that CRTP does not perform adequately over links built on cellular radio access technology, and it is suggested that a more robust header compression scheme must be developed to make IP telephony over cellular economically viable.
Efficient transport of voice over IP over cellular links
TLDR
It is shown that CRTP/UDP fails to deliver sufficient service quality at the error rates of a cost-efficient cellular system and that ROCCO combined with UDP Lite can provide an IP-based voice service over such cellular systems.
Wireless real-time IP services enabled by header compression
The world of telecommunications is currently going through a shift of paradigm from circuit switched, connection oriented information transfer towards packet switched, connection-less transfer. For
Capacity and speech quality aspects using adaptive multi-rate (AMR)
TLDR
The aim is to show the gain provided by an AMR system compared with an existing GSM system using second generation EFR and HR (half rate) coders, and show that there is a trade-off between capacity increase and speech quality degradation.
RObust Checksum-based header COmpression (ROCCO)
TLDR
This document describes a more robust header compression scheme that is adaptable to the characteristics of the link over which it is used and also to the properties of the packet streams it compresses.
The challenges of voice-over-IP-over-wireless
TLDR
Third-generation wireless systems— which go under the names of IMT-2000, UMTS, and EDGE (ETSI/3GPP)— will extend the services provided by current second-generation systems with high data-rate capabilities, for instance, for wireless access to the Internet.

  • 1 December 2002
TLDR
This document describes lower layer guidelines for robust header compression (ROHC) and the requirements ROHC puts on lower layers and general guidelines and guidelines specific for cellular systems are discussed.
Voice-over-IP-over-wireless
TLDR
Solution-header compression and traffic classification-and figures indicating that for WCDMA, voice over IP can be competitive with traditional circuit switched speech services are presented.
