Abstract:
1. A method of controlling operation of first and second wireless communication networks both operating in a predetermined frequency band, the first communication network being operable to communicate within a plurality of first network channels within the predetermined frequency band, the second communication network being operable to communicate within at least one second network channel within the predetermined frequency band, each second network channel coexisting in a frequency range occupied by a plurality of the first network channels, the method comprising: determining whether there are data to be communicated within a communication network channel of one of the first and second wireless communication networks; transmitting a channel restriction message to another of the first and second wireless communications networks, the channel restriction message instructing prevention of communication within another of the first and second wireless communications networks on at least one network channel in another of the first and second wireless communications networks coexisting in a frequency range occupied by the communication network channel; instructing communication within one of the first and second wireless communications networks on the communication channel; and receiving an indication of quality of service of data traffic in the first and second wireless communication networks and scheduling transmission of the channel restriction message to minimize disruption to the data traffic in the first and second wireless communication networks having a higher quality of service.
