Telecommunications networks
First Claim
1. A mobile telecommunications network including a plurality of nodes, each serving one or more cells, and a network core (3), wherein a plurality of mobile telecommunications devices are registered with the network and communicate with the network core via the nodes, wherein the mobile telecommunications devices are provided with a respective subscriber identity module (SIM), and wherein authentication information is stored thereon under the control of the mobile telecommunications network core, wherein the mobile telecommunications network core 3 itself stores details of each of the SIMs issued under its control, wherein a plurality of relays, each serving a cell, are provided between at least one of said nodes (5) and at least one of said telecommunications devices (1) to extend the radio coverage provided by the said node (5), and wherein one of said relays comprises a joining relay (20) which is operable to connect to said node (5) via another of said relays (22), the network including an analyzer that analyzes characteristics of the path between the joining relay (20) and the network core (3) and for selectively changing the path to facilitate optimization of the path between the joining relay (20) and the network core (3).

Abstract
An SAE/LTE or 4G cellular telecommunications network is disclosed which comprises a plurality of eNodeBs 5 and a network core 3. A plurality of mobile telecommunications devices 1 are registered with the network and communicate with the network core 3 via the eNodeBs 5. A joining relay 20 and at least one other relay 22 is provided between the eNodeB 5 and the mobile telecommunications device 1 to extend the radio coverage provided by the eNodeB 5. The joining relay 20 analyses the characteristics of the path between the joining relay and the eNodeB 5 and selectively changes the path to optimise the path.
