Abstract
A method performed by a first network control node for routing a signaling request in a communication system comprising a home communication network and a visiting communication network. The signaling request originates from a communication device subscribing to the home communication network and having a home subscriber identification (ID). The communication device is registered to the visiting communication network with a local subscriber ID different from the home subscriber ID, the local subscriber ID being associated with the home subscriber ID. The method comprises receiving the signaling request originating from the communication device, the signaling request comprising the local subscriber ID, and detecting that the local subscriber ID is associated with the home subscriber ID. The method further comprises, in the signaling request, replacing the local subscriber ID with the home subscriber ID, and sending the signaling request comprising the home subscriber ID to a subscriber database of the home network.
