Telecommunication system for relaying cellular coverage
First Claim
1. A cellular communication device configured to provide an aggregator function, the cellular communication device comprisinga radio system for establishing a wireless connection to a cellular radio area network;
- a base station radio system configured to act as a base station for establishing cellular wireless connections with one or more other cellular communication devices; and
a security function configured to establish a secure connection with a cellular core network, via a cellular radio area network to which the radio system has established a wireless connection;
wherein the secure connection is utilized to carry data from and to the base station radio system and is carried, at least in part, by a further secure connection between a base station of the macro radio area network and a macro security gateway of the core network, and using an aggregator Access Point Name (APN) of the cellular core network used only by devices providing aggregator functions, to an aggregator security gateway of the cellular core network, the aggregator APN providing access to the aggregator security gateway.

Abstract
A cellular telecommunications network architecture is described where certain UEs are configured to assist the network to improve coverage in regions of poor radio conditions. In certain embodiments, appropriate UEs are selected to act as a dynamic, out-of-band coverage extensions. Network performance can thereby be improved when serving users at the cell edge (or in other poor radio condition regions of a cell). Data from UEs connected to those assisting UEs is encrypted to allow secure transit of data without requiring modification to the RAN or Core Network.
