Delaying network reselection following performance of a circuit switched fallback procedure in a call failure scenario

摘要

A method for delaying network reselection by a wireless communication device following a call failure is provided. The method can include determining an initiation of a voice call while connected to a first network. The method can further include participating in a circuit switched fallback (CSFB) procedure to transition from the first network to a second network in response to initiation of the voice call. The method can additionally include determining an occurrence of a call failure of the voice call. The method can also include, responsive to the call failure, barring reselection to the first network for a threshold barring period.

1. A method for delaying network reselection by a wireless communication device following a call failure, the method comprising:
at the wireless communication device:
establishing a connection to a Long Term Evolution (LTE) network;participating in a circuit switched fallback (CSFB) procedure to transition the wireless communication device from the LTE network to a legacy network for handling a voice call via a circuit switched (CS) domain;attempting the voice call via the legacy network;determining an occurrence of a call failure associated with the voice call attempt;barring reselection to the LTE network for a threshold barring period after determining the occurrence of the call failure;attempting a successive voice call via the legacy network during the threshold barring period; andreselecting to the LTE network upon expiration of the threshold barring period when the successive voice call attempt fails.
