Abstract: A method for providing a secure transmission of packet data on a plurality of network access modes in a packet data network. The UE-1 comprises a processing module for initiating communication with one or more receiving UE-2, operating a spread spectrum access (SS) middleware for communicating to a service application (SA) server for retrieving available access modes of the one or more receiving UE-2. The processing module retrieves available access modes for the one or more receiving UE-2, randomly breaks up an uplink transmission of packet data on multiple transmissions of packet data on available access modes of the UE-1 and sends packet data of the transmissions on available access modes of the UE-1.

Abstract: A method and scrambling module for degrading delay-sensitive traffic quality in a telecommunications network, wherein data packets that meet a pre-defined rule are detected and delayed by inducing a delay. The scrambling module comprises an access list comprising the pre-defined rule(s) for detecting certain data packets, a packet detector configured to detect the data packets that meet the pre-defined rule, and a delay inducer module acting to induce a delay to the data packets. The delay is variable for consecutive data packets and may follow a seesaw-like function, a random function, or any other type of function for consecutive data packets. The data packets are detected based on the rule, which may contain indications for intercepting the data packets based on their origination from a certain application port number, destination to a certain application port number, origination from an address identified in the pre-defined rule, or destination to a certain address.
