Abstract: A method for controlling application access to network slicing service at a User Equipment (UE). The method includes: issuing an activation request for establishing network connectivity service for an application executing at the UE, the activation request including an application identifier of the application; determining a network slice for the application based on the activation request; performing a verification of the determined network slice, in accordance with network slicing operator policies; and upon successful verification of the determined network slice, creating a binding between the application identifier and the determined network slice.

Abstract: A method, a synchronization server, a corresponding terminal, and a system for transmitting a message intended for a first terminal, referred to as a destination terminal, from a second terminal, referred to as a source terminal, to at least one third terminal, referred to as an associated terminal, sharing a same identifier with the source terminal. The method includes transmitting from the source terminal to a synchronization server a first synchronization message, in which the message intended for the destination terminal is inserted, and recovering by using the at least one associated terminal the message intended for the destination terminal from the synchronization server by using at least a second synchronization message.

Abstract: A method, a gateway, a synchronization server, a corresponding terminal and a system for transmitting a message intended for a first terminal, referred to as a destination terminal, from a second terminal, referred to as a source terminal, to at least one third terminal, referred to as an associated terminal, sharing a same identifier with the destination terminal. The method includes, following reception of the message by a gateway, transmitting from the gateway to a synchronization server the message by using a first signaling protocol and recovering by the at least one associated terminal the message intended for the destination terminal from the synchronization server by using a first synchronization message.
