Wireless network operation on license-exempt band
First Claim
1. An apparatus, comprising:
- at least one processor; and
at least one memory storing a computer program;
in which the at least one memory with the computer program is configured with the at least one processor to cause the apparatus to at least;
receive from a first device a first broadcast message which comprises a network identifier for an enabling station;
use the network identifier to associate with the enabling station and obtain from it a list of at least one license-exempt channel, in which the at least one license-exempt channel comprises at least a portion of television white spaces (TVWS) spectrum;
join a first ad hoc network with the first device, in which the first broadcast message comprises a first identifier for the first ad hoc network;
transmit a second broadcast message which comprises the network identifier for the enabling station;
receive from a third device a third broadcast message which comprises a second identifier for a second ad hoc network; and
to select joining the first ad hoc network over the second ad hoc network based on at least one of;
a service offered in the first ad hoc network but not in the second ad hoc network; and
recognizing the first ad hoc network as trusted.

Abstract
An apparatus receives from a first device a first broadcast message/beacon which comprises an identifier for an enabling station, then uses the identifier to associate with the enabling station to obtain from it a list of at least one license-exempt channel (e.g., TV whitespaces). In one embodiment the apparatus can then join an ad hoc network (IBSS) with the first device and transmit a second beacon which comprises the identifier for the enabling station. If the apparatus hears multiple beacons advertising different IBSSs, it can select to join the first device'"'"'s ad hoc network over the other(s) based on a service offered or the first device'"'"'s network being trusted. Various examples are detailed for where in the beacon frame the identifier (e.g., SSID) might be placed. In one example the apparatus and first device are Mode I devices and the enabling station is a Mode II device under (draft) IEEE802.11af.

7. A method, comprising:
-
receiving from a first device a first broadcast message which comprises a network identifier for an enabling station; and using the network identifier to associate with the enabling station and obtain from it a list of at least one license-exempt channel, in which the at least one license-exempt channel comprises at least a portion of television white spaces (TVWS) spectrum; joining a first ad hoc network with the first device, in which the first broadcast message comprises a first identifier for the first ad hoc network; transmitting a second broadcast message which comprises the network identifier for the enabling station; receiving from a third device a third broadcast message which comprises a second identifier for a second ad hoc network; and selecting to join the first ad hoc network over the second ad hoc network based on at least one of; a service offered in the first ad hoc network but not in the second ad hoc network; and recognizing the first ad hoc network as trusted. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer readable memory storing a computer program which when implemented by at least one processor causes the at least one processor to execute instructions, comprising:
-
code for reading a network identifier for an enabling station from a first broadcast message received from a first device; code for using the network identifier to associate with the enabling station and to obtain from it a list of at least one license-exempt channel, in which the at least one license-exempt channel comprises at least a portion of television white spaces (TVWS) spectrum; code for joining a first ad hoc network with the first device, in which the first broadcast message comprises a first identifier for the first ad hoc network; code for inserting the network identifier for the enabling station in a second broadcast message for transmission; code for reading a second identifier for a second ad hoc network from a third broadcast message received from a third device; and code for selecting to join the first ad hoc network over the second ad hoc network based on at least one of; a service offered in the first ad hoc network but not in the second ad hoc network; and recognizing the first ad hoc network as trusted. - View Dependent Claims (14)
