Motivation

• Considering IEEE 802.16 radio system as
• Broadband wireless service system
• Fixed Wireless Access or mobile communication
  system applications
• Service convergence with IP network as core
  network
• Competition with cellular network
• Prominent prospects on Broadcasting and LBS
• Necessity of new killer applications Location
  Based MBS
• Keeping existing protocols with additional
  functions in BS

4
Limitations for Internet Broadcasting

• Necessity of unique IP address
• Not enough IP addresses to be assigned
• Difficulty of managing IP addresses, especially
  for mobile unit
• Client-server model Client access request to
  server.
• Necessity of pre-knowledge of web site address of
  server (even multicasting IP address)
• Every time click is needed to request
  information.
• So much load to server and network as increasing
  number of users
• Not enough solutions for broadcasting
• Not enough solutions for user location information

Benefits of LB MBS

• No necessity of receiver IP address
• No DHCP server
• No IP address managing
• No limitation of number of receivers
• No necessity of pre-knowledge of web site address
  information request
• Just listening and tuning of broadcast data
• Less load for broadcasting server
• Sending datagram to each RAS not to terminals
• Less traffic generation to network
• No privacy problem of user location information
• No violations to existing protocols !

Control Message

• Control field for broadcasting parameters of AR
• Optional protocol between server and AR
• repetition period, repetition duration,
  priority control
• authentication, scrambling, etc.
• Type of data field
• Message format between server and terminals
• According to this, users can filter interesting
  data only.
• Terminals can use for their own purposes.

Simplified format of UDP data field

5) Data Broadcasting
1) Broadcasting Announcement
2) Req. Broadcasting
This seems like multicasting protocol, but
more simple, and no need of many multicasting
addresses.
