Appendix C. LIF Mobile Location Protocol

The Location Interoperability Forum (LIF) is an initiative established jointly by Ericsson, Motorola, and Nokia to define and promote a common and ubiquitous solution for determining the location of mobile devices across different wireless network boundaries. The members of LIF include a mix of network operators, equipment manufacturers, and service providers responsible for deploying equipment for this solution. LIF has developed a standards-based solution to locate mobile devices called the Mobile Location Protocol. Issues considered in developing the Mobile Location Protocol specification include the following:

• How to ensure end user privacy and location information security

• How to locate legacy phones (with no existing positioning capability)

• How to offer location services to roaming users

• How to support applications developed internally, by third-party developers and by service providers

• Availability of location capable terminals

• Interoperability of equipment and applications provided by multiple vendors

• Provisioning, billing, and revenue-sharing models
