Abstract: A method for indicating routing capacity related data or routing delay related data via signalling messages in a core network of a telecommunications network using Diameter messages of a Diameter protocol includes: transmitting a first piece of routing capacity related information from a first Diameter enabled network node to a second Diameter enabled network node, and transmitting a second piece of routing capacity related information from the first Diameter enabled network node to the second Diameter enabled network node. The first and second pieces of routing capacity related information are transmitted by at least one Diameter message, wherein the first piece of routing capacity related information comprises aggregated routing capacity data or aggregated routing delay data related to a first routing alternative, and the second piece of routing capacity related information comprises aggregated routing capacity data or aggregated routing delay data related to a second routing alternative.

Abstract: A method for indicating an emergency call availability to a Mobile Equipment includes: storing, at a memory device attached to the ME, information regarding the possibility of unauthenticated emergency calls in dependency of availability data, determining that the ME is in a limited service state; and indicating, by the ME, emergency call availability. The availability data indicates, for at least a first mobile telecommunications network and a second mobile telecommunications network, whether: all unauthenticated emergency calls are allowed with or without an identification module inserted in the ME, unauthenticated emergency calls are only allowed if a valid identification module is inserted in the ME, or unauthenticated emergency calls are not allowed.
