1. A method for mediating between diameter type signaling network peers, the method comprising: identifying, by a network peer mediating device, a source equipment type and a release version for signaling network peers based on pre-defined automatic identification and classification rules, wherein each of the signaling network peers is associated with a different telecommunication service provider or a different application vendor; classifying, by the network peer mediating device, the application vendor of an implemented diameter application in each of the signaling peers; retrieving, by the network peer mediating device, conversion rules adapted for the identified source equipment type or application vendor, wherein the conversion rules adapted for the application vendor comprise message structure rules, content type rules, or content value rules; intercepting, by the network peer mediating device, messages of any communication session comprising an exchange of data between the signaling peers of different telecommunication service providers; applying, by the network peer mediating device, access control rules for validating the intercepted messages; applying, by the network peer mediating device, steering rules on outgoing messages for selecting a destination route of receiving signaling peers; applying, by the network peer mediating device, filtering rules to eliminate redundant information in the data exchanged in the at least one communication session; applying, by the network peer mediating device, the conversion rules to the intercepted messages to translate between message formats of the different signaling peers.
