The invention relates to handling and signaling associated with multicall capability in radio communication systems. The invention enables to combine user equipment, radio access networks and core networks with different multicall capabilities. Therefore, multicall capabilities of user equipment are sent to a network, wherein said capabilities are compared with capabilities within the network. Said capabilities are processed and information about capabilities is returned to the user equipment. The network and user equipment handle call requests according to said capabilities depending on user settings and the number and kind of currently ongoing calls. |
