DC CAFCFirst Claim
1. A method of routing a short message in a communication network, the method comprising:
- receiving said short message at a first network node and screening said short message to determine if said short message is forwardable;
forwarding said short message to a second network node if said first network node determines that said short message is forwardable;
receiving said short message at said second network node and screening said short message based at least in part on a set of criteria; and

Abstract
A method and system for controlling the use of a short message service in a telecommunication system that includes a telecommunication network, a terminal device by which a subscriber is connected to the network, a mobile services switching center connected to the network, a gateway connected to the network, a short message service center connected to the gateway, and a database (DB) connected to or associated with the gateway. A short message sent by an originating subscriber is checked as to whether the short message is among those deemed non-allowed. Forwardable short messages are directed to the gateway, from which the database is queried to determine whether the originating subscriber is permitted the short message to the intended recipient or, alternatively, whether the message should been blocked based on predetermined criteria.

13. A system for routing a short message in a communication network, the system comprising:
-
a first network node configured to receive the short message from a terminal device and screen the short message to determine if the short message is forwardable; if the first network node determines that the short message is forwardable, the first network node configured to forward the short message to a second network node; the second network node configured to receive the short message from the first network node and screen the short message based at least in part on a set of criteria; and if the set of criteria are satisfied by the short message, the second network node configured to forward said short message. - View Dependent Claims (14, 15, 16, 17, 18, 19)
