Abstract:
A technique for providing an asymmetric multipoint call between a plurality of network nodes (10, 12, 14, 16, 18) in a communication network supporting distributed call and connection management (DCM) features is provided, wherein a first call is established between a master node (10) and a first slave node (12) and a second call is established between the master node (10) and a second slave node (14). A method implementation of the technique comprises the steps of exchanging call management information for the asymmetric multipoint call between the master node (10) and the first slave node (12) based on the first call, exchanging call management information for the asymmetric multipoint call between the master node (10) and the second slave node (14) based on the second call, and excluding the first (12) and the second (14) slave node from directly exchanging call management information relating to the asymmetric management call between each other.
