Abstract: The present invention relates to a method to protect, in a secured container using an encryption key, a set of mixed sensitive and public data to be transferred to an entity. The method includes the steps of: generating a random key, ciphering the set of mixed sensitive and public data using said random key to obtain a ciphered set of data, generating an initialization value, and defining configuration information for the secured container. The initialization value, the configuration information and random key form a preamble. The preamble and the ciphered set of data are encrypted. The initialization value renders the resulting encrypted data variable from a secured container to another even in case of repetitive configuration information in the preamble.

The re-instantiating step is automatically triggered by the step of updating the initial operating system.

Abstract: A method for operating a low-mobility wireless device in a cellular network, wherein the low-mobility wireless device operates with an active base node, and the low-mobility wireless device operates in a first mode, in which measurements of transmissions of base nodes are diminished. When the cellular network is enhanced by a new base node, the active base node transmits a first indication at least to the low-mobility wireless device. The low-mobility wireless device, in response to the reception of the first indication, switches to a second mode of operation, comprising execution of at least one measurement of transmissions of base nodes, and transmits at least one measurement report to the then-active base node. The active base node, upon reception of a measurement report, updates neighbour relation data relating to the base node identified by a base node reference with information obtained from the received measurement report.
