IDENTITY MODULE WITH INTERCHANGEABLE UNIQUE IDENTIFIERS

摘要

A telecommunications system is provided, comprising a plurality of different cellular telecommunications networks, an identity module registrable on the plurality of different networks and containing multiple unique identifiers, each unique identifier being associated with a respective network; and, a device, operative in accordance with the identity module, to communicate with the networks when the identity module is registered on that network. The identity module comprises a common security key associated with at least two of the unique identifiers such that the identity module is registrable on each one of the plurality of networks when a unique identifier of the identity module and its associated security key are authenticated for that network.

1. A telecommunications system comprising:
a plurality of different wireless telecommunications networks; an identity module registrable on the plurality of different networks and containing multiple unique identifiers, each unique identifier being associated with a respective network; and, a device, operative in accordance with the identity module, to communicate with each of the networks when the identity module is registered on that network, wherein the identity module comprises a common security key associated with at least two of the unique identifiers such that the identity module is registrable on each one of the plurality of networks when a unique identifier of the identity module and its associated common security key are authenticated for that network, wherein the identity module attempts to connect to one of the plurality of networks using the unique identifiers in accordance with a predetermined sequence, wherein the service platform is operative to instruct the identity module to reorder the predetermined sequence of unique identifiers, wherein the identity module is operative to reorder the predetermined sequence of identifiers upon instruction, and wherein the reordered sequence of unique identifiers is calculated in dependence on one or more criteria selected from a group comprising the diagnostic data transmitted from the identity module, cellular coverage, signal strength, cost, service quality, device priority and predicted device functionality on the network.
