Abstract
Disclosed is a method and apparatus and system for managing frequency use in a system where multiple air interface protocols are in use. When a wireless communication device (WCD) is operating under a particular air interface protocol on a particular frequency channel, the WCD detects a threshold signal under another air interface protocol, and the WCD responsively transitions from operating under the particular air interface protocol on the particular frequency channel to operating under the particular air interface protocol on a different frequency channel. The method may thereby help to reduce likelihood of interference.
Claims19
A method comprising:
- while a wireless communication device (WCD) is operating under a first air interface protocol on a first frequency, the WCD detecting a threshold signal under a second air interface protocol;
- and
- responsive to the detecting, the WCD transitioning from operating under the first air interface protocol on the first frequency to operating under the first air interface protocol on a second frequency,
- wherein transitioning from operating under the first air interface protocol on the first frequency to operating under the first air interface protocol on the second frequency comprises a feature selected from the group consisting of (i) in an idle mode, transmitting a re-registration message and (ii) in an active mode, receiving a handoff directive.
A method for managing frequency use by a wireless communication device (WCD), the method comprising:
- the WCD being served under a first air interface protocol on a first frequency channel;
- while the WCD is being served under the first air interface protocol on the first frequency channel, the WCD detecting a threshold strong signal under a second air interface protocol;
- and
- responsive to the WCD detecting the threshold strong signal under the second air interface protocol while the WCD is being served under the first air interface protocol on the first frequency channel, the WCD transitioning from being served under the first air interface protocol on the first frequency channel to being served under the first air interface protocol on a second frequency channel,
- wherein transitioning from being served under the first air interface protocol on the first frequency channel to being served under the first air interface protocol on the second frequency channel comprises a feature selected from the group consisting of (i) in an idle mode, transmitting a re-registration message and (ii) in an active mode, receiving a handoff directive.
A wireless communication device (WCD) comprising:
- a first radio for operating under a first air interface protocol;
- a second radio for operating under a second air interface protocol;
- and
- control logic operable, when the first radio is operating under the first air interface protocol on a first frequency, to make a determination that the second radio is detecting a threshold strong signal under the second air interface protocol, and
- responsive to the determination to cause the first radio to transition from operating under the first air interface protocol on the first frequency to operating under the first air interface protocol on a second frequency,
- wherein transitioning from operating under the first air interface protocol on the first frequency to operating under the first air interface protocol on the second frequency comprises a feature selected from the group consisting of (i) in an idle mode, transmitting a re-registration message and (ii) in an active mode, receiving a handoff directive.
