US Patent 10271359 Wireless communication system

A host (100) provides a service to a dockee (120) via wireless docking. The host has a host wireless communication unit (102) and a near field receiver (103). When the user places the dockee near the host within a near field communication (153) distance, a near field transmitter (123) transmits a service search signal comprising a dockee identifier and a dockee service list for indicating services which are relevant to the dockee. The host determines a matching service set of services that are available at the host, and transmits, via the host communication unit, a service available signal comprising the dockee identifier and the matching service set via the host communication unit. The dockee processor determines whether the received dockee identifier corresponds to the dockee identifier and any of the matching services is actually required by the dockee, and if so, initiates the wireless docking with the host.
