Abstract:
1. A method for wireless communications, comprising: obtaining at least one of a plurality of circuit switch fall back (CSFB) parameters from at least one of an LTE eNodeB or a usable system, wherein the plurality of CSFB parameters comprise a channel list, a system time, and a neighbor list; determining if any of the plurality of CSFB parameters are usable and updating a matrix to indicate the usability of the obtained CSFB parameters, where the matrix defines system acquisition procedures based on usable CSFB parameters; performing a full system acquisition process defined by the matrix when one or more of the plurality of CSFB parameters are not useable; and performing a comprehensive system acquisition process defined by the matrix when each of the plurality of CSFB parameters is useable.
