It is necessary to transfer between entities of a Public Land Mobile Network (PLMN) information specific to the PLMN in order to deal with the specific behaviour of roaming mobile stations. The Signalling System No. 7 specified by CCITT is used to transfer this information. This European Telecommunication Standard (ETS) describes the requirements for the signalling system and the procedures needed at the application level in order to fulfil these signalling needs.
