Telecommunications Networks
First Claim
1. A telecommunications network, comprising:
- a radio access network; and
a network core operable to page a mobile terminal, wherein at least one element of the network is operable to receive mobile terminating data from the network and to determine whether that mobile terminating data can be delivered to the mobile terminal, and wherein said at least one element is operable to instruct the network core to page the mobile terminal if the mobile terminating data cannot be delivered to the mobile terminal.

Abstract
A telecommunication system includes a first radio access technology having a first radio access network and a first network core operable to page a mobile terminal via at least one element of the first radio access technology. The telecommunications system also includes a second radio access technology having a second radio access network and a second network core operable to page said mobile terminal via at least one element of the second radio access technology. Each of these elements may receive the page from its radio access technology, determine whether the mobile terminal is registered with that radio access technology and notify its core network if the mobile terminal is not registered. The core network may cause the mobile terminal to be paged in the other radio access technology. Different timer periods for idle timers at mobile terminal and eNodeB may avoid possible loss of mobile terminating data.

2. A telecommunications network, comprising:
-
a radio access network; and a network core, wherein at least one element of the network is operable to receive mobile terminating data destined for a mobile terminal from the network and to determine whether the mobile terminal is in an active state and to notify the core network if the mobile terminal is not in the active state.

14. A telecommunications network, comprising:
a radio access network comprising a plurality of nodes, a core network, and a plurality of telecommunications terminals for communicating with the core network via an associated one of said nodes, the telecommunications terminals each having a timer which expires after a first duration after a triggering event, and the nodes each having a timer which expires after a second duration after a triggering event, wherein the expiry of the telecommunications terminal timer causes the telecommunications terminal to enter an idle or inactive communication state and the expiry of the node timer causes the node to notify the core network that the terminal has entered an idle or inactive communication state, and wherein said second duration is shorter than said first duration and by the arrangement being such that, in response to a triggering event of the telecommunications terminal timer and the node timer, the telecommunications terminal enters the idle or inactive state after the associated node has notified the core network. - View Dependent Claims (15, 16)

17. A telecommunications system, comprising:
-
a first radio access technology having a first radio access network and a first network core operable to send data to a mobile terminal via at least one element of the first radio access technology; and a second radio access technology having a second radio access network and a second network core operable to send said data to said mobile terminal via at least one element of the second radio access technology, wherein at least one of said core networks is operable to reconfigure said data from a form suitable for sending by said first radio access technology into a form suitable for sending by said second radio access technology. - View Dependent Claims (18)

19. A method of operating a telecommunications network including a radio access network and a network core which pages a mobile terminal, the method comprising:
-
receiving at least one element of the network mobile terminating data from the network; determining whether the mobile terminating data can be delivered to the mobile terminal; and instructing the network core, via said at least one element, to page the mobile terminal if the mobile terminating data cannot be delivered to the mobile terminal. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of operating a telecommunications network including a radio access network comprising a plurality of nodes, a core network, and a plurality of telecommunications terminals for communicating with the core network via an associated one of said nodes, the telecommunications terminals each having a timer which expires after a first duration after a triggering event, and the nodes each having a timer which expires after a second duration after a triggering event, the method comprising:
-
at the expiry of the telecommunications terminal timer, causing the telecommunications terminal to enter an idle or inactive communication state; and at the expiry of the node timer, causing the node to notify the core network that the terminal has entered an idle or inactive communication state, wherein said second duration is shorter than said first duration such that, in response to a triggering event of the telecommunications terminal timer and the node timer, the telecommunications terminal enters the idle or inactive state after the associated node has notified the core network. - View Dependent Claims (31, 32)
