5. 3/7/01Alcatel/SignalSoft Contribution: TR45.2 LFG Location Information Restriction (LIR) LIR Modes –Unconditionally Restricted –Restricted with Exception List (Fixed) –Restricted with Exception List (Variable) –Unrestricted Type of Activation –Demand (Subscriber administrable) –Permanent (Operator administrable)

6. 3/7/01Alcatel/SignalSoft Contribution: TR45.2 LFG Proposed Application Class Regulatory or Legal Internal Network Operation Application Subscribed to by user –This application appears in the exception list of the user. Application invoked by user –This application is invoked explicitly by the subscriber, e.g. by dialing *sushi –Or application provided by serving wireless network (who may or may not own the HMPC)

7. 3/7/01Alcatel/SignalSoft Contribution: TR45.2 LFG Mapping LIR – Application Class Mechanics If user has LIR = Unconditionally Restricted –Only Regulatory or Legal and –Internal Network Operation are allowed. If user has LIR = Restricted (Fixed) –Only Regulatory or Legal and –Internal Network Operation and. –Application Subscribed to by user are allowed If user has LIR = Restricted (Variable) –Only Regulatory or Legal and –Internal Network Operation and. –Application Subscribed to by user –Application invoked by user are allowed

8. 3/7/01Alcatel/SignalSoft Contribution: TR45.2 LFG Mapping LIR – Application Class Reasoning We want to keep exception list of subscribers (allowed LCS Client IDs) in only the HMPC and not have to be passed around the wireless network (potentially a large list of LCS Clients per subscriber) HMPC can do the initial screening of LCS Client IDs. HLR or VLR can do screening based on LIR mode and proposed application class as seen in previous slide

9. 3/7/01Alcatel/SignalSoft Contribution: TR45.2 LFG Other stuff to do Minimize the amoutn of info that travels through network –Could POSREQTYPE and PQOS be combined? Do we need to send LCSClientID to the user? Verizon requirement. –Used so that the user can accpet or reject request for position – but the user may not even know which ClientIDs (numbers) he wants. –Maybe sending a 4 letter name or acronym would be better. Others?…
