Method and apparatus for searching radio technologies
First Claim
1. An apparatus comprising:
- at least one processor configured to perform a first search for a first radio technology and obtain search results indicating frequency channels acquired for the first radio technology, and to perform a second search for a second radio technology using the search results for the first search to omit frequencies from the second search; and
a memory coupled to the at least one processor.

Abstract
Techniques to improve searches for wireless networks are described. A terminal uses results of a search for one radio technology to reduce the search space for another search for the same radio technology or a different radio technology. In one scheme, a first search for a first radio technology (e.g., GSM) is initially performed, and search results indicating frequency channels acquired for the first radio technology are obtained. A second search for a second radio technology (e.g., W-CDMA) is performed using the results of the first search to omit frequencies from the second search. In another scheme, acquisition is performed on at least one frequency channel previously acquired for a radio technology (e.g., W-CDMA). A search for the radio technology is then performed using results of the acquisition to omit frequencies from the search.
