Abstract
In some examples, in response to determining that a new communication channel is required, a wireless device retrieves information provided from a network node of availability of alternative communication channels for the wireless device. In response to retrieving information that a second communication channel is available for a location within which the wireless device is located, the wireless device removes wireless device specific information and initiates a request to connect to the second communication channel, where the second communication channel is in a frequency range different from a frequency range of the first communication channel.
Claims20
A method at a network node, comprising:
- in response to determining by the network node that a wireless device is using a first communication channel in a first geographical area, initiating, at the network node, a database query of availability of alternative communication channels for the wireless device within the first geographical area;
- and
- in response to identifying that there is a second communication channel within the first geographical area, informing, by the network node, the wireless device that the second communication channel is available for the wireless device within the first geographical area.
A network node comprising:
- one or more processors;
- and
- a non-transitory storage medium storing instructions executable by the one or more processors to:
- based on determining by the network node that a wireless device is using a first communication channel in a first geographical area, initiate, at the network node, a database query of availability of alternative communication channels for the wireless device within the first geographical area;
- and
- based on identifying that there is a second communication channel within the first geographical area, inform, by the network node, the wireless device that the second communication channel is available for the wireless device within the first geographical area.
A non-transitory machine-readable storage medium storing instructions that upon execution cause a network node to:
- based on determining by the network node that a wireless device is using a first communication channel in a first geographical area, initiate, at the network node, a database query of availability of alternative communication channels for the wireless device within the first geographical area;
- and
- based on identifying that there is a second communication channel within the first geographical area, inform, by the network node, the wireless device that the second communication channel is available for the wireless device within the first geographical area.
