Patent ID: 8537799

Claim:
A method comprising: providing, from a wireless wide area network (WWAN) device of a communication system, a WWAN communication schedule associated with the WWAN device to a wireless local area network (WLAN) device of the communication system, wherein the WWAN device is coupled with the WLAN device; determining, at the WWAN device, a WWAN communication time interval associated with the WWAN device for performing WWAN communication operations and a WLAN communication time interval associated with the WLAN device for performing WLAN communication operations based, at least in part, on a coexistence signal received from the WLAN device; determining, at the WWAN device, whether the WWAN communication time interval is in progress to determine whether to perform one or more WWAN communication operations; in response to determining that the WWAN communication time interval is in progress, determining, at the WWAN device, whether to handoff control to the WLAN device to initiate the WLAN communication time interval; transmitting, to a base station to which the WWAN device is connected, a control message indicating absence of WWAN data at the WWAN device for transmission to the base station, in response to determining to handoff control to the WLAN device to initiate the WLAN communication time interval; and performing, at the WWAN device, the one or more WWAN communication operations in response to determining that the WWAN communication time interval is in progress and in response to determining not to handoff control to the WLAN device.
