1. A method comprising:
- invoking an overlay function configured to assist an apparatus in performing system selection among a plurality of different types of systems based on a set of overlay parameters, wherein the set of overlay parameters comprises an indication of system priority among the plurality of different types of systems, wherein the indication of system priority does not include an indication of priority among different networks of a system, wherein the set of overlay parameters does not comprise a preferred roaming list or a public land mobile network list; and
in response to determining that the set of overlay parameters specifies that a higher priority system is to be acquired, initiating a scan to attempt to acquire a network of the higher priority system, wherein priority among networks of the higher priority system is specified separately from the set of overlay parameters.

Abstract
A mobile station includes at least one radio frequency transceiver, a data processor and a memory coupled to the data processor. The memory stores information that includes an overlay function and overlay parameters for use by the data processor to perform system selection by invoking the overlay function to determine if the overlay parameters specify that a home system is to be acquired and, if so, to initiate a scan using the transceiver to attempt to acquire the home system using home system-related overlay parameters, else attempting to acquire a non-home system.
