BSSAP+ Stack: Architecture

• Enables usage as a GPRS BSSAP+ stack or UMTS BSSAP+ stack through different compile time options
  
• Communication with VLR via SCCP class 0 connectionless service
  
• Uses return option in SCCP and handles N_NOTICE indication from SCCP. Supports on/off mode at run-time
  
• Integrated with Aricent SCCP, MTP-3 stacks
  
• Optional support over Aricent SIGTRAN stack
  

BSSAP+ Stack: Ports

• Sun-Solaris Port
  
• Other ports can be built within 3-4 weeks
  

Conformance to AAPE™

• Modularity
  
  • Layered architecture
    
  • Stack data structures are hidden from the outside world
    
  • Compile time exclusion of functionality
    
• Multiple configuration options – multi-tasking/single-thread and message-based/functional interface
  
• Porting effort restricted to modules involving operating system interfaces; error handling/reporting, external interfaces
  
• Customization of task architecture, custom event handlers and communication between modules
  
• Debugging support
