15.1.4.2 Directory Response Parameters
Response Parameters
A collection of one or more of the parameters below. Name
Mandatory? Data Type
Description
POIContext N
POIWithDistanceType A list of one or more POIs and there distance from the
request location. Points of Interest
Distance pairs N
List of POI and Distance Integer
pairs List of all Point of Interest
records satisfying the request and the distance
from the source location. Distance will be zero for
WithinBoundary request.
15.1.4.3 Notes:
a. Depending on the nature of the query, some terms within the query may be mandatory or not.
b. The proximity query performs a spatial filter on a list of Points of Interest. These POIs may be listed explicitly by a unique identifier ID, Name,
Coordinate, Coordinate List, Address or derived from categories, formal categories or keywords within a Directory Type.
15.2 Part 2: Gateway Service
This is the interface between the GeoMobility Server and Location Server that resides in the GMLC or MPC through which OpenLS services obtain position data for Mobile
Terminals. This interface is modeled after the MLP specified in OMA 3.0 for Standard Location Immediate Service.
15.2.1 Use cases
These use cases have been grouped into 3 priority categories, with priority 1 having the highest priority and the only case for mandatory support.
The Gateway Service should support the following:

14 Use Case
Priority
Client requests a single mobile terminal’s immediate location.
1
Client requests single mobile terminal’s periodic location 2
Client requests multiple mobiles’ immediate location 2
Client requests single mobile terminal’s triggered location 3
Client request multiple mobiles’ periodic location 3
Client requests multiple mobiles’ triggered location 3
15.2.2 A Location Request Use Case
A subscriber wants to use a Location-Based Service. The Gateway Service is employed to obtain the position of the subscriber’s mobile terminal from the network. A Location
Service Client sends the request to determine a position to the Gateway. The Gateway calculates the position of the subscriber’s mobile terminal and forwards to the Location
Service Client, which may store it for as long as needed.
15.2.3 Request Parameters
