TELECOMMUNICATIONS NETWORKS

摘要

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 oneother relay (22) is provided between the e Node B (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 e Node B (5) and selectively changes the path to optimise the path.
