Wireless telecommunications network authentication

A method of managing a telecommunications network, the telecommunications network having a first user and a second user, the method comprising the step of: ascertaining a competitive characteristic associated with the first user and a competitive characteristic associated with the second user; comparing the ascertained competitive characteristics; identifying whether there is a disparity between the competitive characteristics that exceeds a threshold, thereby to identify a competitive advantage associated with the first or second user; and if it is identified that the disparity exceeds the threshold, adapting a network configuration of a network connection associated with the first user so as to offset the competitive advantage associated with the first or second user.

Network management

A method of controlling an Autonomous Vehicle (AV), comprising the steps of: detecting a fault in a first AV-; in response to detecting said fault, transmitting a communication for alerting an AV of the fault, wherein said communication is a device-to-device wireless communication; receiving said communication at a second AV-; identifying the second AV as being capable of retrieving at least part of the first AV and delivering said at least part to an intended destination; and instructing the second AV to perform the retrieving and delivering.

Vehicle management

A method of selecting competitors for a multi-user competitive activity being performed over a telecommunications network, in which a first UE and a second UE are in communication with the telecommunications network, and the telecommunications network providing at least one network slice, wherein the method comprises the steps of: identifying a network slice onto which the first UE is allocated; identifying a network slice onto which the second UE is allocated; determining that the first UE and the second UE are intending to participate in the multi-user competitive activity; and selecting the first UE and the second UE to participate in the multi-user competitive activity in dependence on the identified network slices onto which the first UE and the second UE is allocated.

Competitor selection

A method of authenticating a device subscribed to a first wireless communication network on a second wireless communication network, the method including: deriving at a node within the first wireless communication network a set of one or more network keys for the second wireless communication network from one or more network keys of the first wireless communication network that uniquely identify the device within the first wireless communication network; communicating the derived set of one or more network keys to the device; storing a first copy of the derived set of one or more network keys within an identification module at the device and a second copy of the derived set of one or more network keys within a secure area of the device; and authenticating the device on the second wireless communication network using the second copy of the derived set of one or more network keys stored in the secure area of the device.
