Satellite Terminal Access Stratum

Abstract: HSC has been involved in Design, development and integration of Satellite Access Stratum (AS). based on 3GPP Release 6 Specifications. HSC was responsible for complete AS Design/development as well as integration with multiple interfaces viz. Non-Access Stratum (NAS), Physical Layer, Network and Platform.

Salient features of Project are:

  • UT System Architecture/Design
  • Participation in RLC/MAC/RRC Air Interface Specifications and NAS-AS Interface specifications for Satellite Environment
  • Test Environment design and development for Control and Data Path Testing
  • Integration of Satellite AS components with L1/DSP (Customer HW), NAS and Satellite BSS
  • AS optimizations:
    • Zero byte header compression for VoIP
    • Simultaneous support for Dedicated and Packet Channels
    • Zero buffer copy

Customer Benefits:

  • Support to Customer in finalizing Air Interface Specifications and finalizing interfaces with NAS Vendor
  • Developed elaborate test setup to do real-time testing of Data Path. Test setup was reused in Sub-system and System Integration
  • Proactive support towards System and Sub-system Integration
