Abstract:
Certain aspects of the present disclosure relate to techniques for increasing the emergency call success rate by reducing the number of retries in a same domain. According to one aspect, a multi-mode user equipment may measure a first time period upon a first attempt of establishing an emergency call in a first RAT network. The UE may use a configurable parameter to determine a number of times that the UE may retry the emergency call in the first RAT network after expiration of the first time period without establishing the emergency call or after a failed attempt of the emergency call during the first time period. The UE may switch to a second RAT network if the UE fails in establishing the emergency call in the first RAT network after retrying the determined number of times.
