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
WiCoN Lab.Hansung Univ. 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.
Control field type of data field broadcast data
Simplified format of UDP data field

* This seems like multicasting protocol, but more simple, and no need of many multicasting addresses.
