2 SIP Signaling Protocol Interaction Entities in need for location information - Emergency Services Routing Proxy - Public Safety Answering Point ESRP PSAP Location Server stores information about a particular subscriber or knows where to retrieve it from. Location Server Diameter server collects information about the current attachment point of the device. Diameter Server HELD Diameter Parameter Query Single Admin. Domain

3 Properties Main use case of authors is location information. Then generalized. Corresponds to a “SELECT ‘foo’ FROM database WHERE username=‘bar’; Query contains the AVP codes that are desired for a given user. Response provides the AVPs corresponding to that query.
