Abstract
A wireless communication system attempts to acquire service from one of a plurality of possible service provider systems. If service is acquired by a less desirable service provider system, the wireless communication system of the present invention constructs an alternate list of more desirable service provider systems and periodically attempts to acquire service from a more desirable service provider system. The wireless communication system may include a most recently used (MRU) list of recently acquired service provider systems. The MRU list may be used to sort the list of alternate service provider systems so that the alternate list of service provider systems will first list those service provider systems that are also contained in the MRU list. Data entries that are contained in both the alternate scan list and the MRU list are sorted in accordance with the position of the service provider system within the MRU list.
