    abstract =  {This document provides a problem statement, lists requirements, and captures design aspects for a GEOPRIV Layer 7 (L7) Location Configuration Protocol (LCP). This protocol aims to allow an end host to obtain location information, by value or by reference, from a Location Information Server (LIS) that is located in the access network. The obtained location information can then be used for a variety of different protocols and purposes. For example, it can be used as input to the Location-to-Service Translation (LoST) Protocol or to convey location within the Session Initiation Protocol (SIP) to other entities. This document is not an Internet Standards Track specification; it is published for informational purposes.},
