Apparatus and method to perform fast neighbor list search during a transfer to a different RAT target system

摘要

A method, an apparatus, and a computer program product for wireless communication are provided for reducing the amount of time for sending a measurement report message, such as a Pilot Strength Measurement Message (PSMM), after sending a completion message in wireless communication. A first radio access technology is monitored, and an indication is received on a second radio access technology. Before a transfer is made to the second radio access technology based on the indication, a UE receives neighbor information for the second radio access technology via the first radio access technology. Thereafter, a transfer is performed to transfer the UE from the first radio access technology to the second radio access technology.

1. A method for reducing an amount of time for reporting a measurement report message after sending a completion message for a transfer from a first Radio Access Technology (RAT) to a second RAT in wireless communication, the method comprising:
monitoring a first RAT; receiving an indication on a second RAT; prior to a transfer from the first RAT to the second RAT based on the indication:
receiving neighbor information for the second RAT via the first RAT,searching an environment based on the neighbor information, andgenerating a first neighbor list based on the neighbor information; performing the transfer from the first RAT to the second RAT; and after the transfer:
receiving a second neighbor list via the second RAT,comparing the first neighbor list to the second neighbor list to determine an active neighbor list, andconfiguring the measurement report message based on the determined active neighbor list, wherein the transfer includes an x-way soft handoff based on a fast neighbor scan of the neighbor information that results in a soft handoff status and the x in the x-way soft handoff comprises an integer equal to or greater than 1.
