1. An apparatus comprising processing circuitry configured to control:
- an address identifier configured to maintain a serving network position entity address of a serving network position entity of a serving network by storing the address of the serving network position entity at a mobile station; and
a location identification request generator configured to receive an indication of the serving network position entity address maintained at said address identifier, said location identification request generator configured to generate a location identification request when a mobile station employing the apparatus is positioned at the serving network, the location identification request routed to the serving network position entity identified by the serving network position entity address without inquiry to a home network of the mobile station in response to a location service being requested by sending the location identification request to the address stored at the mobile station,wherein the serving network position entity address stored is a pre-configured value to enable interaction directly between the mobile station and the serving network for location services without inquiry to the home network.

Abstract
Apparatus, and an associated method, for facilitating performance of location services for a mobile station that roams beyond its home network. A cache is provided at the mobile station. The cache is populated with a value identifying the address of the serving position server. When a location service is requested, the cache is accessed, and a message is sent to the address identified in the cache. The cache is updatable, such as through the generation and forwarding of a message to the mobile station by the home position server responsive to registration of the mobile station.

11. An apparatus comprising processing circuitry configured to control:
-
a home-network message generator positioned at a home network associated with a mobile station, said home-network message generator configured to generate a message for delivery to a serving network position entity of a serving network when the mobile station enters the serving network, the message identifying authentication indicia associated with the mobile station required by the serving network position entity, the home-network message generator being further configured to provide the mobile station with a serving network position entity address to be stored at the mobile station to enable the provision of position identification information to the mobile station without inquiry to the home network in response to a location service being requested, wherein the serving network position entity address stored is a pre-configured value to enable interaction directly between the mobile station and the serving network for location services without inquiry to the home network. - View Dependent Claims (12, 13, 14, 15, 21)

16. A method comprising:
-
maintaining a serving network position entity address of a serving network entity at a mobile station by storing the serving network position entity address at the mobile station; and generating a message for delivery to the serving network position entity using the serving network position entity address stored at the mobile station, the message identifying a location service requested by the mobile station, the location service to be provided by the serving network position entity in relation to provision of position identification information to the mobile station without inquiry to the home network in response to a location service being requested, wherein the serving network position entity address stored is a pre-configured value to enable the mobile station to interact directly with the serving network entity for location services without inquiry to the home network. - View Dependent Claims (17, 18, 19, 20)
