U Co M Protocol

  1. 1. Presence, Location Awareness, Power Management and IP Phone (Infrastructure mode) UCoM Demonstration (Multi-Radio Wireless LAN Research)
  2. 2. Step 1: Presence, Location & Power - Infrastructure Mode <ul><li>SmartBrick is plugged into UCoMProxy ; its presence is detected and registered with UCoMServer </li></ul>
  3. 3. Step 1: Presence, Location & Power - Infrastructure Mode <ul><li>SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer </li></ul><ul><li>Receiver enters room and MiniBrick registers with the UCoMServer via SmartBrick & UCoMProxy </li></ul>Receiver
  4. 4. Step 1: Presence, Location & Power - Infrastructure Mode <ul><li>SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer </li></ul><ul><li>Receiver enters room and MiniBrick registers with the UCoMServer via SmartBrick & UCoMProxy </li></ul><ul><li>UCoMCaller queries UCoMServer to determine MiniBrick ’s presence & location </li></ul>Receiver UCoMCaller
  5. 5. Step 1: Presence, Location & Power - Infrastructure Mode <ul><li>SmartBrick is plugged into UCoMProxy; its presence is detected and registered with UCoMServer </li></ul><ul><li>Receiver enters room and MiniBrick registers with UCoMServer via SmartBrick & UCoMProxy </li></ul><ul><li>UCoMCaller queries UCoMServer to determine MiniBrick’s presence & location. </li></ul><ul><li>UCoMCaller sends a “wakeup” request to MiniBrick via UCoMServer . The UCoMServer forwards request to UCoMProxy & Smart Brick . </li></ul><ul><li>MiniBrick powers on the Receiver </li></ul>“ Wakeup” “ Wakeup” Receiver Power’s On!
  6. 6. Step 2: People Discovery, Location, iPhone <ul><li>Receiver invokes uTalk and registers with UCoMServer according to step 1 </li></ul>
  7. 7. <ul><li>Receiver invokes uTalk and registers with UCoMServer according to step 1 </li></ul><ul><li>Caller invokes uTalk to contact UCoMServer and determine if receiver is present and powered on </li></ul>Step 2: People Discovery, Location, iPhone
  8. 8. Step 2: People Discovery, Location, iPhone <ul><li>Receiver invokes uTalk and registers with UCoMServer according to step 1 </li></ul><ul><li>Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on </li></ul><ul><li>If receiver is present If receiver is powered on then Caller sends call request along with its IP address to UCoMServer , which relays request to receiver else Caller sends a wakeup request to UCoMServer which wakes up receiver </li></ul>
  9. 9. Step 2: People Discovery, Location, iPhone <ul><li>Receiver invokes uTalk and registers with the UCoMServer according to step 1 </li></ul><ul><li>Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on </li></ul><ul><li>If receiver is present If receiver is power on then Caller sends a call request along with its IP address to the UCoMServer, which will relay the request to receiver else Caller sends a wakeup request to the UCoMServer which will in turn wake up receiver </li></ul><ul><li>Receiver opens a connection to caller, and they talk in real-time using the infrastructure network </li></ul>
