ENHANCED INTER-RADIO ACCESS TECHNOLOGY (IRAT) CELL RESELECTION

摘要

A cell reselection technique establishes a data call on a different radio access technology (RAT) when a background application requests initiation of a data call while camped on a serving RAT. Rather than setting up the data call immediately on the serving RAT, a user equipment (UE) determines signal quality of the other RAT. When the signal quality is good, the UE delays call setup until after reselecting to the other RAT.

主权项

1. A method of wireless communication, comprising:
receiving a request to initiate a data call from a background data application while in idle mode in a first radio access technology (RAT); checking a signal quality of a cell of a second RAT in response to receiving the request to initiate the data call; and delaying call set up procedures in the first RAT when the signal quality is above a cell reselection threshold and a cell reselection timer is running and not expired.
