FIELD: radio communications.
SUBSTANCE: method is claimed for notifying radio communication network (RAN) about selected CN operator from client equipment (UE) in a system, where a set of CN operators are present, who use RAN jointly. On request of IDT transmission UE receives ID of CN operator, selected from a list of ID, broadcasted by cell, to which connection is set up, and transmits IDT message from ID of selected CN operator to RAN network. On receipt of IDT message RAN determines, whether IDT includes ID message of selected CN operator. In case of presence of ID of selected CN operator, RAN saves ID of selected CN operator in UE-context. In case of absence of ID of selected CN operator, RAN reads saved ID of selected CN operator from UE-context.
EFFECT: ensured precise routing and reduced signaling losses.
