While a WCD is being served by a base station of a first network, the base station may detect both a fallback trigger and a handover trigger. The fallback trigger may be a trigger to initiate a fallback setup procedure, where the fallback setup procedure involves execution of a sequence of steps including a particular step. The handover trigger may be a trigger to initiate a handover procedure. The base station determines that the handover trigger was detected before execution of the particular step of the fallback setup procedure. Responsive to determining that the handover trigger was detected before execution of the particular step, the base station (a) foregoes the fallback setup procedure and (b) transmits to the WCD a message directing the WCD to establish communication with the second network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic setup of fallback communications during handover","description":"A method and system to help avoid a failed eCSFB call setup in the presence of handover.
