Abstract:
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 ).
