A method of authenticating User Equipment (UE) to a wireless telecommunications network, wherein the UE is subscribed to a first wireless telecommunications network, and authenticating being performed so as to subscribe the UE to a second wireless telecommunications network, and wherein there is an absence of a roaming capability between the first wireless telecommunications network and the second wireless telecommunications network for the UE, the method including generating, at the first wireless telecommunications network, a network key for authenticating the UE at the second wireless telecommunications network; loading the generated network key to the second wireless telecommunications network; subsequently communicating the generated network key to the UE from the first wireless telecommunications network; and authenticating the UE at the second wireless telecommunications network by communicating the network key from the UE to the second wireless telecommunications network, thereby to permit the UE to subscribe to the second wireless telecommunications network.

Wireless telecommunications network authentication

A method of allocating spectrum to a signal in a wavelength division multiplex network including a plurality of nodes, wherein the spectrum comprises a grid divided into a plurality of slots, including allocating to the signal a slot immediately adjacent to a second slot occupied by a second signal, wherein the signal and the second signal are both addressed to the same destination node, and wherein the slots allocated to the signal and the second signal form a spectrum block.

Optical network design and routing

A routing and wavelength assignment method for use in an optical fiber system, comprising: (i) identifying a plurality of paths between a source node and a destination node, (ii) selecting one of the plurality of identified paths, (iii) defining within the spectrum band of the selected path one or more blocks of spectral resource, in which each block comprises either: one or more unused wavelength channels, or one or more wavelength channels having the same spectral width, (iv) obtaining an entropy value of the selected path defining the spectrum fragmentation across its spectrum band, based on a logarithm of the ratio of the number of wavelength channels in each of the one or more blocks, to the total number of wavelength channels across the spectrum band, (v) iterating (ii) to (v) until the entropy value of each of the plurality of identified paths has been determined, and (vi) choosing from the plurality of identified paths a path having the lowest entropy value.

Optical data transmission

A routing and wavelength assignment method for use in an optical fiber network includes (i) identifying a path between each node pair in the network, (ii) identifying a block of spectral resource within the spectrum band of the identified path of a selected node pair, (iii) calculating a spectrum entropy value of the identified path of the selected node pair based on a logarithm of the ratio of the number of wavelength channels in each of the one or more blocks, to the total number of wavelength channels across the spectrum band, (iv) iterating (ii) and (iii) in respect of each of the paths between each other node pair in the network, until a spectrum entropy value of all the paths between all the node pairs has been calculated, (v) summing the spectrum entropy value of all of the paths between all of the node pairs to obtain a network spectrum entropy value in respect of a network configuration based on the paths between the node pairs, and (vi) determining from the network spectrum entropy value whether a signal carrying a demand through the network is separated from any other signals by a spectral gap sufficient to accommodate a change in the demand to an expected level.
