Home and roaming provisioning method for mobile terminals

摘要

A telecommunication terminal for accessing a data network via an access network using a set of provisioning data stores a current set of provisioning data and at least one set of protected provisioning data. The protected provisioning data cannot be updated without the intervention of the terminal user. This enables a mobile terminal to change access network without losing the provisioning data of the home access network. It avoids the need for further provisioning on returning to the home access network.
