Method for allowing access to services offered by an intelligent mobile communications network

A method of making network services available to a subscriber of a first mobile communications network when the subscriber roams in a second mobile communications network, comprising:

• intercepting a signaling message issued by a service switching function of the second mobile communications network as a consequence to a service request by the subscriber;
• checking the intercepted signaling message;
• and
• based on a result of the check, updating the intercepted signaling message to include service addressing data adapted to invoke a service in the first mobile communications network.

A mobile communications network comprising network apparatuses adapted to make network services available to a subscriber of the mobile communications network when the subscriber roams in a visited mobile communications network,

• wherein the network apparatuses comprise a service addressing function comprising:
• a signaling message interceptor adapted to intercept a signaling message issued by a service switching function of the visited mobile communications network as a consequence to a service request by the subscriber;
• a signaling message parser adapted to check the intercepted signaling message;
• and
• a signaling message modifier adapted to update the intercepted signaling message based on a result of the signaling message check, so that the updated message comprises service addressing data address for invoking a service in the mobile communications network.

An apparatus for use in a mobile communications network, comprising:

• a signaling message interceptor adapted to intercept a signaling message received by the mobile communications network, and issued from a service switching function of a visited mobile communications network in which a subscriber of the mobile communications network is roaming as a consequence to a service request by the subscriber;
• a signaling message parser adapted to check the intercepted signaling message;
• and
• a signaling message modifier adapted to update the intercepted signaling message based on a result of the signaling message check, so that the updated signaling message comprises service addressing data address for invoking a service in the mobile communications network.
