An information handling system of a Radio Access Network (RAN) system operating a secure network slice orchestration system may comprise a network interface device of the RAN system transceiving data within a 5G New Radio (NR) frequency band with an endpoint computing device, the network interface device receiving an instruction from a client solutions management (CSM) platform to assign a network slice within the 5G NR frequency band, based on a security profile associating the endpoint computing device with a security tier, to a network slice as established by a software defined network (SDN) controller within a sub-portion of the 5G NR frequency band, the secure network slice orchestration system determining the endpoint computing device is associated with the network slice within a communications profile received from the CSM platform, and the SDN controller establishing a virtual access point transceiving data within the network slice with the endpoint computing device.

The invention relates to a method for determining an access right to a service, the method comprises: receiving a service request, generating at least one token, the at least one token being broadcast by at least one beacon device; receiving a message comprising at least data interpretable as a token, data from which the at least one beacon device is identifiable and data from which a position of the terminal device is derivable. By applying the received pieces of data it is possible to determine if an access to the service may be granted to the terminal device. The invention also relates to a network controller, a communication system and a computer program product.

Various techniques and systems are described herein for anonymization of basic service set identifiers (BSSIDs) for wireless access points (WAPs). In various examples, a first WAP may determine a first BSSID. The first WAP may generate a first beacon packet comprising the first BSSID. A first client packet may be received, the first client packet comprising the first BSSID as a destination address of the first client packet. A determination may be made that at least a threshold amount of time has passed since the first BSSID was designated for use in beacon packets. Thereafter, the first WAP may determine a second BSSID different from the first BSSID. The first WAP may generate a second beacon packet comprising the second BSSID.

A random acoustic phase scrambler device is installed in-line with a telecommunications fiber link to prevent voice detection via fiber links. The device includes a transducer to produce vibrations; a length of optical fiber positioned to receive the vibration from the transducer; and a random acoustic phase driver configured to control the intensity and frequency of the vibrations. The transducer produces randomized vibrations within an acoustic bandwidth. The device is configured to introduce device-induced phase changes to signals within the telecommunications fiber link. The bandwidth of the device-induced phase changes is greater than the bandwidth of voice-induced phase changes, and the device-induced phase changes are greater in intensity than the voice-induced phase changes. The device-induced phase changes mask voice-induced phase changes through the telecommunications fiber link that are otherwise detectable by voice detection equipment tapped to the telecommunications fiber link.

Various embodiments of the invention are detection systems and methods for detecting call provenance based on call audio. An exemplary embodiment of the detection system can comprise a characterization unit, a labeling unit, and an identification unit. The characterization unit can extract various characteristics of networks through which a call traversed, based on call audio. The labeling unit can be trained on prior call data and can identify one or more codecs used to encode the call, based on the call audio. The identification unit can utilize the characteristics of traversed networks and the identified codecs, and based on this information, the identification unit can provide a provenance fingerprint for the call. Based on the call provenance fingerprint, the detection system can identify, verify, or provide forensic information about a call audio source.

A user equipment, a method performed by user equipment, and a chipset provided in a user equipment each encompass receiving a paging message including an indication from a current serving cell of the user equipment, the indication triggering a frequency redistribution procedure in which the user equipment reselects a target cell belonging to a frequency different from a frequency of the current serving cell, to be used as a serving cell, and performing the frequency redistribution procedure in response to receiving the paging message including the indication.

A telecommunication device includes an audio signal transmission unit configured to receive an audio signal and to transmit the same to a further telecommunication device. The telecommunication device further includes a signaling unit configured to output a signaling when there is a concern that the audio signal is acoustically understandable for third parties or represents a disturbance for third parties. A further telecommunication device includes an audio signal receive unit configured to receive an audio signal from a further telecommunication device and to output the same acoustically, and a signaling unit configured to output a signaling when there is a concern that the output audio signal is acoustically understandable for third parties or represents a disturbance.

A method of operating a second network access node comprises configuring the second network access node to act as a secondary network access node for a dual connectivity mode for a terminal device in which a first network access node acts as a master network access node. The method further comprises establishing, while acting as a secondary network access node for the dual connectivity mode, that the second network access node should switch to acting as a master network access node, deriving a new master network access node security key for use by the second network access node when switched to acting as a master network access node for the dual connectivity mode, and configuring the second network access node to act a master network access node for the dual connectivity mode using the new master network access node security key.
