The present document is a technical report that summarises the work on the UTRAN Release 5 work item "Radio Access Bearer Support Enhancements". The work items comprises of two areas of study:
  • Robust header compression
  • SRNS context relocation
Each study area includes the requirements of the proposed feature, a description of the basic mechanism and a discussion of the issues involved. A recommended solution is provided and impacts to other RAN WGs are analysed.
