METHODS AND SUBSCRIBER DATA STORAGE NODES FOR HANDLING SIGNALING REQUESTS IN A COMMUNICATION SYSTEM

摘要

A method performed by a subscriber data storage node of a visiting communication network for handling a signalling request in a communication system comprising a home communication network and the visiting communication network. The signalling request originates from a communication device subscribing to the home communication network and having a home subscriber identification, ID, for communication in the home communication network. 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 signalling request originating from the communication device, the signalling request being associated with the local subscriber ID and identifying that the local subscriber ID is associated with the home subscriber ID. The method further comprises requesting a subscriber data from a subscriber data storage node of the home communication network, the request comprising the home subscriber ID, and receiving the subscriber data from the subscriber data storage node of the home communication network.

1. A method performed by a subscriber data storage node of a visiting communication network for handling a signalling request in a communication system comprising a home communication network and the visiting communication network, the signalling request originating from a communication device subscribing to the home communication network and having a home subscriber identification (ID) for communication in the home communication network, the communication device being 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 comprising:
receiving the signalling request originating from the communication device, the signalling request being associated with the local subscriber ID; identifying that the local subscriber ID is associated with the home subscriber ID; requesting a subscriber data from a subscriber data storage node of the home communication network, the request comprising the home subscriber ID; and receiving the subscriber data from the subscriber data storage node of the home communication network.
