Apparatus, and associated method, for providing location service to a roaming mobile station

摘要

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.
