METHOD FOR A COMMUNICATION UNIT TO PARTICIPATE IN MULTIPLE CALLS

摘要

While participating in a group call on a first wireless communication resource (114), senior members (104-107) of a communication group (108) can initiate a semi-private call. A central controller (110) allocates a second wireless communication resource (115) for the semi-private call. Furthermore, executive members (106-107) can initiate an executive call to be established on a third wireless communication resource (116). Executive members can participate in the executive call, the semi-private call, and the group call, whereas senior members can participate in the semi-private call and the group call. Junior members (101-103), normally allowed to participate only in the group call, can be selected by senior members to temporarily participate in the group call and the semi-private call.
