Normally, when a user equipment (UE) is connected to a public safety answering point (PSAP)—e.g., is on a 911 call—all incoming calls are automatically routed to voicemail. In contrast, the systems and methods disclosed herein enable calls that were dialed within a predetermined time window of the 911 call to be sent through to call-waiting to enable the user to accept or reject the call. The system can use a “guard timer” to determine whether a call is within the predetermined time window. The system can include a single guard timer for all incoming calls—e.g., “any call made from the UE within the previous X minutes prior to the 911 call.” The system can also include individual guard timers for each call that expire separately relative to the call's proximity to the 911 call."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Guard timer to optimize E911 call handling","description":"Systems and methods for optimized call handling during e911 calls.
