Abstract:
1. A telecommunications network system, comprising: a first radio access technology including a first radio access network and a first network core; a second radio access technology including a second radio access network and a second network core, wherein the first network core and the second network core are operable to page a mobile terminal, wherein at least one element of the telecommunications network system is operable to receive mobile terminating data from the radio access networks and to determine whether the mobile terminating data can be delivered to the mobile terminal, wherein said at least one element is operable to instruct at least one of the network cores to page the mobile terminal if the mobile terminating data cannot be delivered to the mobile terminal, wherein the at least one element receives the mobile terminating data from a particular one of the radio access technologies, determines whether said mobile terminal is camped with the particular one of the radio access technologies and notifies the at least one of the network cores if the mobile terminal is not camped with the particular one of the radio access technologies, wherein the mobile terminal has an active state in which a cell occupied by the mobile terminal is known and an idle or inactive state when the cell occupied by the mobile terminal is not known but in which a last area known to be occupied by the mobile terminal is recorded, and wherein the state of the mobile terminal determines signaling performance when the mobile terminal moves from one of the radio access technologies to the other of the radio access technologies.
