Abstract
A method for routing a terminating call to a user equipment via a first control node for controlling the call, wherein the user equipment is attached to a second control node which is adapted to provide routing information. The method comprises determining, by the second control node, if the user equipment is attached to the second control node over a third control node, wherein the attachment over the third control node indicates that call control shall be performed by a specific service domain. Based on the determining, the provided routing information is selected by the second control node, wherein the routing information indicates to the first control node if the further call establishment to the user equipment is controlled either by the second control node or by the third control node. The call is then routed, by the first control node, according to the selected routing information.
