Problems solved by technology

In this way, a wireless communication device can remain "stayed" on a traditional wireless network for a period of time after terminating a voice connection, for example, to service an ongoing data connection, and the user of the wireless communication device may communicate via Correspondingly experience lower-than-expected data performance compared to slower traditional wireless networks

Abstract

Method and apparatus for facilitating return to a first wireless network from a second wireless network by a wireless communication device is provided. A method includes the wireless communication device engaging in data transfer for an application session on the first wireless network; participating in a CSFB procedure to transition from the first wireless network to the second wireless network for servicing a voice connection; buffering data received for the application session before and / or during the CSFB procedure; releasing the voice connection; discontinuing requests for downlink data for the application session in response to termination of the voice connection to provide a gap in data transfer; reselecting to the first wireless network during the gap in data transfer; using the buffered data to continue the application session during reselection; and resuming data transfer for the application session on the first wireless network after completing reselection.

Description

technical field [0001] Embodiments described herein relate generally to wireless communications, and more particularly to facilitating return from a second wireless network to a first wireless network after performing a Circuit Switched Fallback (CSFB) procedure. Background technique [0002] Cellular wireless networks using newer Radio Access Technology (RAT) systems such as Long Term Evolution as standardized by the Third Generation Partnership Project (3GPP) are being developed and deployed. (LTE) system and Long Term Evolution-Advanced (LTE-A) system. Cellular wireless networks using these newer RATs, which may be referred to as fourth generation (4G) and higher RATs, often support faster data rates and / or newer / different services than legacy RAT-based cellular wireless networks Set, the legacy RATs, such as second generation (2G) and third generation (3G) RATs, include Universal Mobile Telecommunications System (UMTS) networks and Global System for Mobile Communication...
