Abstract
The invention relates to a method for optimising routing to a first user equipment (T1, T2) roaming in a visited network (OP B, OP C) in a communications system comprising at least a home network (OP A), a visited network (OP B, OP C) and a relaying network (IPX, IPX1, IPX2, IPX3, IPX4). The method of the invention comprises storing (2-4, 3-2, 3-4, 3-6) a location information of a first user equipment (T1, T2) to a database (DB) external to the home network (OP A) and the visited network (OP B, OP C), the location information being associated with an identification information of the first user equipment (T1, T2); receiving (2-6, 3-10) a message from a second user equipment (T1, T2); recognizing (3-12) at least one identification information of the first user equipment (T1, T2) in the message; comparing (3-14, 3-16) the identification information stored in the database (DB) with the identification information received in the message; and if the both identification information matches, routing (2-8, 3-26) a communication according to the location information of the first user equipment (T1, T2).

7. A method for optimizing routing to a first user equipment roaming in a visited network in a communications system comprising at least a home network, the visited network and a relaying network, the method comprising:
-
storing location information of the first user equipment to a database external to the home network and the visited network, the location information being associated with identification information of the first user equipment; receiving a message from a second user equipment; recognizing the identification information of the first user equipment in the message; comparing stored identification information stored in the database with the recognized identification information received in the message; and in the event said comparing determines a match of the stored identification information and the recognized identification information, routing a communication according to the stored location information of the first user equipment. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A device for optimizing routing to a first user equipment roaming in a visited network in a communications system comprising at least a home network, the visited network and a relaying network, the device being adapted to:
-
receive location information of a first user equipment, the location information being associated with identification information of the first user equipment; store the location information in a database external to the home network and the visited network; receive a message from a second user equipment; recognize the identification information of the first user equipment in the message; retrieve stored identification information of the first user equipment from the database; compare the stored identification information stored in the database with the recognized identification information received in the message; and if the stored identification information and the recognized identification information match, provide routing information for and/or route a communication according to the stored location information of the first user equipment.
