Non Trusted User Plane Update

• Enabling Non-Trusted User Plane roaming is
  similar to enabling Control Plane Roaming
• An Inter-MPC L3 interface needs to be supported
• V1/V2 fully define this interface / protocol
• A variant of OMA RLP could be used
• Both UP and CP will require unique variants of
  RLP
• With the exception of V1 NI the IS-41 RSP issue
  is not relevant so in fact enabling Non-Trusted
  UP roaming should be easier than enabling CP
  roaming
• H-MPC simply needs a SID/NID mapping to the V-MPC
  address
• It was agreed at the last LBS Roaming Summit
  that the V1/V2 interface / protocol would be used

InterMPC Solution for Nontrusted Model

• For V1/V2 nontrusted an inter-MPC L3-type
  protocol is defined in 80-V6195-2NP and the LBS
  roaming call flows are defined in 80-V8470-2NP
