Abstract
A mobile communication handset which is configured for communicating by a cellular or PCS or cordless call over a first wireless link to a base station, and is also configured for communicating with one or more other communication devices over other respective wireless direct device-to-device second links implemented by the Bluetooth Intercom Profile, is provided with functionality to carry on a group call by appropriately combining speech signals carried by the various links and by the handset. The first wireless link may be a cordless link which is implemented by the Bluetooth Telephony Profile. Alternatively, the first link may also be configured as wireless direct device-to-device link, in which case all wireless links involved in the group call are implemented by the Bluetooth Intercom Profile.
