METHOD AND FILTERING DEVICE FOR FILTERING MESSAGES RECEIVED BY COMMUNICATION NETWORK SUBSCRIBER OVER SERIAL DATA BUS OF SAID NETWORK Russian patent published in 2013 - IPC H04L12/40 

FIELD: radio engineering, communication.

SUBSTANCE: in order to filter incoming messages with a large number of filtering criteria, the filtering device (6) has a list in which several identifier pairs (ID1, ID2) are stored, each defining a range of values limited by a first identifier (ID1) and a second identifier (ID2). The identifier (8) of an incoming message (7) is at least compared to selected identifier pairs (ID1, ID2) and a request is made whether the identifier (8) of the incoming message (7) is greater than, or greater than or equal to the selected first identifier (ID1) and less than, or less than or equal to the selected second identifier (ID2). The incoming message (7), depending on the configuration bit setting (SFM; EFM), is forwarded to an application (5) or rejected, if the identifier (8) of the incoming message (7) lies within the range of values limited by the first identifier (ID1) and the second identifier (ID2).

EFFECT: simple method and efficient consumption of resources.
