Screening of unfamiliar messages and parameters
First Claim
1. Method for preventing or allowing the conveyance of at least one message via a node in a network, the node comprising first and second screening functions, each at least one message comprising a first parameter with information on a type of the message, at least one of the at least one message further comprising a second parameter with information about a destination for the at least one message, whereinwhen the at least one message arrives at the node and the first screening function does not recognize the type of message indicated by the first parameter, the first screening function calls upon a second screening function, which performs an action based on the destination indicated by the second parameter.

Abstract
The present invention relates to a method, a node (105) and a network (102) for screening out unfamiliar messages. The invention is preferably applied in a ISUP network. The screening takes place through when a message or a parameter is detected which is not recognized a function is called upon which looks up the message and destination in a table (401, 601). The table (401, 601) is built up and modified by the operator. If the parameter (603) or message (403) and destination (404, 604) are found in the table then the corresponding action (405, 605) which can be, for example, to not forward the message or parameter, is taken.

11. A node in a network arranged for preventing or allowing the conveyance of at least one message via the node, the node comprising first and second screening functions, each at least one message comprising a first parameter with information on a type of the message, and at least one of the at least one message further comprising a second parameter with information about a destination for the at least one message, wherein
when the at least one message arrives at the node and the first screening function does not recognize the type of message indicated by the first parameter, the first screening function calls upon a second screening function, which performs an action based on the destination indicated by the second parameter.
