Abstract
Abstract A wireless terminal is disclosed that is capable of establishing a communications channel with either a public wireless network or a private wireless network on existing IS-95 CDMA facilities without changing the air interface or requiring the existence of independent private network facilities. Furthermore, a wireless terminal is disclosed that enables a user of a wireless terminal to affect which private wireless network the wireless terminal accesses, again on existing IS-95 facilities and without changing the air interface.The wireless terminal comprises two or more lists of SID/NID signals: a default list and at least one override list. Both the default list and the override list provide a different preference for which public or private network the wireless terminal accesses when a call is placed from the wireless terminal. A switch in the wireless terminal advantageously causes the wireless terminal to use either the default list of SID/NID signals or one of the override lists of SID/NID signals. The switch can be activated either manually by the user or by inserting the wireless terminal into a cradle in accordance with the present invention.
