R1 PAA must be able to obtain location information for a PaC Location credentials may be provided by PaC In this case PaC is colocated with a location module (e.g. GPS receiver) that computes the required credentials PANA messaging will be used to transfer the credentials from PaC to PAA Location credentials could be provided by a third party location provider E.g. In U-TDOA, location is computed by the network provider In this case some out-of-band messaging is required between PAA and location provider Not of concern for us here. |
