LBS Roaming Initiative Update
• LBS roaming initiative quickly nearing completion
• “PDE transaction method” identified as industry solution for user plane user
• Still need to finalize settlement component
• Need to capture all work in a CDG reference document
• Two conference calls and Tampa meeting planned– LBS Roaming Settlement Conference Call, May 7th, 2pm Pacific, 858-845-5000 (ID=3333,
PW=3333)
– LBS Roaming Solution Document Review, June 7th 2pm Pacific, 858-845-5000 (ID=9999, PW=9999)
– Final Face to Face Meeting, June 15th 2007 2:45 p.m. (Tampa Bay Area)

Overview of Settlement• Refers to financial settlement between operators
• Remuneration for services provided to inbound roamers
• Currently performed between operators for packet data roaming. Settlement charges are calculated by the kilobyte.
• Operators indicated this will be a requirement for LBS roaming
– LBS roaming will consume V-PDE resources
– In many cases, LBS roaming volumes between operators will be asymmetrical
• This slide deck investigates LBS roaming settlement for the “remote transaction solution” for user plane LBS roaming

Status of Settlement Solution
• General agreement on LBS usage record solution
• Open questions:– Will CRX be used for settlement?– Create general usage record for multiple
applications? (raised in Macau)– Use existing billing records, e.g. UDRs or DIAMETER
billing records (raised in Macau)

Strawman Location Billing Record (LBR)
• Strawman specifically designed for remote transaction solution
• Strawman is based on proposed inter-PDE protocol
• Assumes:– Billing/Settlement are performed on a per transaction basis– Operators want details of each PDE transaction– Summaries can be generated using LBRs on a periodic basic,
e.g. monthly– No LBR generated for keep alive messages– Detailed logs will also be available on PDEs – possible that
LBRs are generated from logs

Modify LBS to be application billing record?
• Do we expect other applications to need similar billing records? (normally MS accesses home server)
• Can we anticipate the need of future applications?
• Would we compromise the LBR record by trying to accommodate future unknown applications?

RADIUS/DIAMETER UDRs for LBS billing
• UDRs normally for general data access by users
• LBS records only needed for settlement
• Desirable to have LBS billing records in normal billing stream?
• UDR well suited for information required for LBS billing?
