Abstract: 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.
