Abstract: A GTP Triggered Message handling capability is provided for enabling handling of GTP Triggered Messages. A GTP Triggered Message including a GTP Sequence Number and an invalid TEID is received, and one of a plurality of processing elements is selected for the GTP Triggered Message based on the GTP Sequence Number of the GTP Triggered Message. The selected one of the processing elements is selected based on a mapping of a group of GTP Sequence Numbers to the selected one of the processing elements. The GTP Triggered Message is propagated toward the selected processing element such that the GTP Triggered Message may be processed by the selected processing element. In this manner, processing of GTP Triggered Messages having invalid TEIDs may be performed by processing elements which typically process GTP Triggered Messages having valid TEIDs, such that GTP Triggered Messages having invalid TEIDs are not required to be processed by a central processing module before being provided to the processing elements.

Abstract: A re-entrant resonant cavity 12 includes a first metallized molded plastic component 18, which comprises a re-entrant stub 17, an end wall 14 and a cylindrical side wall 13. The component 18 is surface mount soldered to a metallized PCB substrate 19. A rostrum 24 is located facing the end face 21 of the stub 17 to define a capacitive gap 22 with it. The end face 21 of the stub 17 and the rostrum 24 are configured such that relative rotation between them changes the profile of the gap 22 and hence the gap capacitance. By suitably locating the two parts during manufacture, a particular capacitance may be chosen to give a desired resonance frequency from a selection available depending on the relative angular position of the stub 17 and rostrum 24. In another cavity, the rostrum is replaced by an etched metallization layer of a printed circuit board.
