| 摘要 | The present invention relates to specialised mobile communication schemes which are becoming frequently deployed, for example, utility mobile communication schemes such as railway-operator-consortia-managed mobile communications schemes which come under the umbrella term of GSM-Railways (GSM-R) systems. The invention seeks to define an architecture to support the use of 'Functional Numbers' for addressing purposes within a wireless communication network, and provide a method for transporting 'Functional Numbers' between the relevant wireless communication entities within the architecture. The invention also seeks to define a flexible and extendible encoding scheme for the GSM-R defined supplementary service handling operations used for registering, interrogating and deregistering FNs. In addition the invention provide an extension to the way Functional Numbers are registered and deregistered by providing an encoding for supervisory control of registration and deregistration procedures. | ||||||
