An interference avoiding method and apparatus are provided for use in a home network in which different communication protocols are used by different devices in a domain of the home network. The domain is supporting a particular medium. The method avoids interference in the domain of signals of secondary devices with signals of a primary device in the event when the primary device becomes active. The said secondary devices are using available spectrum of the primary device when the primary device is inactive. The method comprises
- determining by a first processing means a common frequency band being common to the different communication protocols being respectively used by each of the secondary devices; and
- determining by a second processing means an escape frequency band within the common frequency band; and
- upon activation of the primary device, by a global master of the home network initiating :
- a commanding control signal towards the secondary devices for a use of the escape frequency band during a predefined period in order to execute its terminating signals which are terminating its communication session; and
- a forbidding control signal towards the primary device in order to forbid during the predefined period a use of the escape frequency band, and thereby avoiding the interference. |
