METHOD AND DEVICE FOR PROVIDING CORRELATION MEANS IN HYBRID TELECOMMUNICATION NETWORKS Russian patent published in 2009 - IPC H04L12/64 

FIELD: physics; communication.

SUBSTANCE: invention relates to communication networks. Combinational networks allow simultaneous connection between user equipment over networks of different network types. For communication sessions on different network types, belonging to the same user equipment, a correlation check is enabled by introducing an identifier denoted as combinational call indicator (CCI). This CCI identifier in combination with the known calling line identity (CLI) identifier enables user equipment and other network entities to perform a correlation check between channel switching calls and packet switching communication sessions, which are ongoing or to be established. User equipment, setting up a related communication session, sets the CCI identifier and provides the CCI identifier when setting up the communication session towards the receiving user equipment or network entity, which enabled checking whether the last received communication session is correlated with an earlier established session due to the presence of the CCI identifier.

EFFECT: improved call setup.
