Abstract
A user device establishes a wireless connection with a wireless local area network using a first radio. The user device then deactivates a second radio of the user device based on establishing of the wireless connection with the wireless local area network. Subsequently, the user device determines whether to activate the second radio based on at least one criterion associated with the wireless connection.
Claims28
A method comprising:
- establishing, by a user device and using a first radio, a wireless data connection with a wireless access point, wherein the user device comprises a second radio in a powered-up state;
- placing the second radio of the user device into a powered-down state responsive to establishing the wireless data connection with the wireless access point;
- determining a signal strength for a signal from the wireless access point;
- determining whether to place the second radio into the powered-up state based on the signal strength;
- and
- placing the second radio into the powered-up state based at least in part on a determination that the signal strength is below a signal threshold, wherein placing the second radio into the powered-up state comprises supplying power to the second radio without transferring the wireless data connection to the second radio.
A user device comprising:
- a wireless local area network (WLAN) radio;
- a mobile telecommunications radio;
- and
- a processing device, coupled to the WLAN radio and the mobile telecommunications radio, wherein the processing device is configured to:
- establish a wireless connection with a WLAN using the WLAN radio;
- place the mobile telecommunications radio into a powered-down state based on establishment of the wireless connection with the WLAN;
- determine whether at least one criterion associated with the wireless connection is satisfied;
- and
- place the mobile telecommunications radio into a powered-up state responsive to a determination that the at least one criterion is satisfied, wherein placing the mobile telecommunications radio into the powered-up state comprises supplying power to the mobile telecommunications radio without transferring the wireless connection to the mobile telecommunications radio.
A non-transitory computer readable medium including instructions that, when executed by a processor, cause the processor to perform operations comprising:
- placing, by the processor, a second radio of a user device into a powered-down state after a wireless connection has been established with a wireless communication system via a first radio of the user device, wherein the powered-down state comprises an unpowered state or a partially powered state in which at least one component of the second radio is unpowered;
- determining, by the processor, whether to place the second radio into a powered-up state based on at least one criterion associated with the wireless connection;
- and
- placing the second radio into the powered-up state responsive to determining that the at least one criterion is satisfied, wherein placing the second radio into the powered-up state comprises supplying power to the second radio without transferring the wireless connection to the second radio.
