Problems solved by technology

[0005] When the communication device directly switches from the 3GPP CS network to the LTE network, it cannot connect to Mobile Terminating (MT) / MO calls, and a ping-pong effect may occur
Due to the ping-pong effect, the communication device will move between the LTE network and the 3GPP CS network very frequently

Abstract

The present invention provides a method and an apparatus for improving a circuit-switched fallback in a wireless communications system in which user equipment can communicate via a first radio access technology and a second radio access technology. A method for improving circuit switched fallback for a user equipment (UE) in a wireless communications system, herein the UE is capable of communicating via first and second radio access technologies (RATS), including: determining that a connection has been released, wherein the connection is associated with a second network corresponding to the second RAT; starting a timer providing a period of time when the connection has been released; and stopping e timer after a condition is satisfied. The method and the device for a circuit-switched fallback in a wireless communications system provided by the invention provide the time period by using the timer, which can effectively avoid the ping-pong effect and further enhance the user experience.

Description

technical field [0001] Aspects of the present invention relate generally to wireless communications, and more particularly, to a method and apparatus for improving Circuit Switched Fallback (CSFB). Background technique [0002] The Long Term Evolution (LTE) of the Third Generation Partnership Project (Third Generation Project Partnership, 3GPP) is called "4G" in the market, and it represents the latest standard of the wireless communication network. LTE uses an Internet Protocol Multimedia Subsystem (IP Multimedia Subsystem, IMS) architecture that utilizes packet-based signaling. However, LTE also provides support for previous technologies (known in the market as "2G" or "3G"), such as the Universal Mobile Telecommunications System (UMTS) platform, the Global System for Mobile Communications (Global System for Mobile Communications, GSM) platforms and Code Division Multiple Access (CDMA) platforms, all of which use a different air interface than LTE and can operate on Circu...
