A data communication system serves a wireless communication device over a Non Third Generation Partnership Project (non-3GPP) network slice. The data communication system receives a request for the non-3GPP slice from the wireless communication device over a non-3GPP access node. The data communication system exchanges network signaling with a 3GPP network. The data communication system receives an authorization from the 3GPP network for the wireless communication device to use the non-3GPP network slice. The data communication system establishes a Virtual Private Network (VPN) for the wireless communication device over the non-3GPP access node in response to the authorization from the 3GPP network. The data communication system exchanges user data with the wireless communication device over the VPN. The data communication system exchanges the user data with a non-3GPP communication system over the VPN or another VPN for the non-3GPP communication system.

Data communications over a wireless communication network slice

Techniques related to the management of communication devices using a combination of local and centralized blockchains to enable the detection of state changes that deviate from the expected behaviors are disclosed. In one example aspect, a method for detecting code injection activity in communication devices by a machine learning based platform includes determining, by a verification system, baseline information about a communication device; detecting a state change of the communication device, responsive to the state change of the communication device; appending, by the verification system, a current-state block representing the state change to a prior-state block representing a previous state of the communication device in a blockchain; and detecting whether a suspicious attack has occurred by comparing the payload of the current-state block to the baseline information.

Code injection prevention for communication devices

Global mobile communication event identifiers (IDs) improve security by enabling early detection of cybersecurity events in cellular networks. The event IDs are each unique to a category of mobile communication events and consistent across the network functions (NF), even from different vendors. NFs assign event IDs to mobile communication events, which are reported to a cybersecurity operations center. The cybersecurity operations center has visibility into network-wide events and is thus able to match occurrences of event IDs with categorized attacks, when an attack is occurring. This enables rapid, intelligent selection of a defensive response.

Global mobile communication event IDs for improved network and security operations

A programmable radio exposure function switches between real-time and near-real-time modes of operation for a radio access network (RAN) intelligent controller of a telecommunications system. An application programming interface is exposed by the radio exposure function and performs radio resource management for the telecommunications system. The application programming interface communicates with services and/or applications to control RAN functions, and allocates RAN resources of the telecommunications system to a user equipment for the services and/or applications. A machine learning module is embedded within the radio exposure function and trained to identify network slices of the telecommunications system for the services and/or applications. The machine learning module analyzes data received from the user equipment to detect that the user equipment has violated a security constraint of the telecommunications system.

A method for configuring a network of a communication system to secure applications executable on user equipment (UE) connectable to the network. The method includes receiving a predefined first traffic signature corresponding to a first application, and configuring a network traffic monitoring tool to detect an activation of the first application executing on the UE. The method additionally includes configuring the network traffic monitoring tool to monitor active traffic manifested on the network associated with the first application, configuring a traffic signature comparison tool to detect a security breach associated with the first application, and configuring an alarm tool issue an alarm and/or act against the first application.

Systems and methods for securing applications executed on communication systems

A wireless communication system delivers a wireless data service to a wireless communication device using content-addressing. The wireless communication system generates a content-address from a data set. The wireless communication system stores the content-address in association with the data set. The wireless communication system encrypts the content-address with a system key and transfers the encrypted content-address to the wireless communication device. The wireless communication device decrypts the encrypted content-address with a user key to obtain the content address. The wireless communication device re-encrypts the content-address with the user key. The wireless communication system receives the re-encrypted content-address from the wireless communication device and decrypts the re-encrypted content-address with the system key to obtain the content-address. The wireless communication system retrieves the data set from the memory circuitry with the decrypted content-address. The wireless communication system delivers the wireless data service to the wireless communication device based on the retrieved data set.

Wireless data service using content-addressing

Systems, methods, and devices are disclosed herein to identify and deploy policy changes from a policy source in a wireless communication network to enforcement points in the network based on trends identified by the policy source in KPIs reported by the enforcement points. In an implementation, enforcement points in the network report KPIs to the policy source. The KPIs are related to authorization attempts made by user equipment in the network. The policy source, upon receiving the KPIs, identifies a trend in the KPIs and identifies a policy change based on the KPIs. The policy source then deploys the policy change to the enforcement points. In various implementations, the policy source is a Policy Decision Point (PDP), and the enforcement points are Policy Enforcement Points (PEPs).

Quality of trust framework for wireless communication networks

In a wireless communication system, wireless communication devices filter smart contract data. The wireless communication devices generate source smart contract outputs. The wireless communication devices select some of the source smart contract outputs. The wireless communication devices select at least one target smart contract. The wireless communication devices transfer the selected source contract outputs to the ones of the selected target smart contracts. The selections that comprise this filtering may be based on device location, device identifier, digital certificates, device application identifiers, device component identifiers, alarms, messages, time, day, date, and/or some other factors.

Smart contract filtration in a wireless communication system

A first wireless network slice executes a first slice input and generates a first slice output. The first slice transfers the first slice output to a second wireless network slice. The second slice receives and authorizes the first slice output and transfers a first acknowledgement to the first slice. The first slice receives the first acknowledgement and responsively uses the first slice output to deliver a data communication service. The second slice executes a second slice input and generates a second slice output. The second slice transfers the second slice output to the first slice. The first slice receives and authorizes the second slice output and transfers a second acknowledgement to the second slice. The second slice receives the second acknowledgement and responsively uses the second slice output to deliver the data communication service.

Synchronized wireless network slicing

A wireless communication network serves a Network Exposure Function (NEF) slice to User Equipment (UE). An Access and Mobility Management Function (AMF) selects a NEF slice for the UE. A Session Management Function (SMF) selects a NEF address for the NEF slice for the UE. A User Plane Function (UPF) exchanges Application Programming Interface (API) calls and responses between the UE and a NEF based on the NEF address. The NEF exchanges the API messages with the UE over the UPF. The NEF slice may comprise an edge NEF slice that is selected based on the geographic location of the UE and that features a local NEF element that is coupled to a core NEF element.
