Method for implementing autonomous management of radio resources across dual networks
First Claim
1. An apparatus, comprising:
- a processing element, wherein the processing element is configured to operate with a cellular radio having a single transmitter to;
communicate with a first cellular network according to a first radio access technology;
notify the first cellular network of a tune-away mode, wherein during a tune-away using the tune-away mode, the cellular radio is configured to tune-away to a second cellular network using a second radio access technology and to be temporarily non-responsive to the first cellular network while maintaining a signaling connection to the first cellular network;
subsequent to operation on the first cellular network and while maintaining a signaling connection to the first cellular network, tune away to the second cellular network according to the second radio access technology to communicate with the second cellular network;
set a timer to a predetermined amount of time upon tuning away to monitor an amount of time the cellular mobile device is tuned away; and
return to communicating on the first cellular network subsequent to the tuning away on the second cellular network, wherein in response to the cellular radio tuning away to the second cellular network for a time that is shorter than the predetermined amount of time, the processing element is configured to operate with the cellular radio to transmit a scheduling request to the first cellular network via the signaling connection even when the cellular radio does not have uplink data to send.

Abstract
Managing radio resources across dual networks includes a wireless mobile device connecting to a first wireless network using a first radio access technology. The wireless device may notify the first network of a capability to be temporarily non-responsive to the first network while maintaining a signaling connection to the first network. The wireless device may communicate with a second network. The wireless device may return to communicating with the first network subsequent to communicating with the second network, and in response to communicating with the second network for less than a predetermined amount of time, the wireless device may send a scheduling request to the first network. In response to receiving a grant acknowledgement from the first network, the wireless device may send a buffer status report that includes a value such as zero to indicate that the wireless device has returned to and can communicate with the first network.

14. A non-transitory, memory medium storing program instructions executable by a processor to:
-
communicate with a first cellular network according to a first radio access technology using a cellular radio having a single transmitter; subsequent to communicating with the first cellular network and while maintaining a signaling connection to the first cellular network, tune away to a second cellular network according to a second radio access technology to communicate with the second cellular network using the cellular radio; set a timer to a predetermined amount of time upon tuning away to monitor an amount of time the cellular radio is tuned away; return to communicating with the first cellular network using the cellular radio subsequent to the tuning away on the second cellular network; in response to the cellular radio tuning away to the second cellular network for a time that is shorter than the predetermined amount of time, send a scheduling request to the first cellular network via the signaling connection to notify the first cellular network that the tune-away operation is complete even if the cellular radio does not have uplink data to send. - View Dependent Claims (15, 16, 17, 18, 19)
