Patent ID: 8780965

Claim:
A method for inter-modem coordination, comprising: establishing a first data connection to a network in a first network coverage area using a first air interface provided by a first modem; detecting a second network coverage area with a second air interface provided by a second modem; upon detecting that the second modem provides a better data service than the established first data connection provided by the first modem, concurrently initiating a first timer by the first modem and a second timer by the second modem for determining a data call state of the second modem and the first modem, respectively; terminating the first data connection to the network upon detecting that the first timer and the second timer have not expired and the data call state of the second modem is no data call; and initiating a second data connection to the network using the second air interface provided by the second modem upon detecting that the data call state of the first modem is no data call or either one or both of the first and second timers are expired.
