An outbound roaming system detects that a wireless device has left a home wireless network and, in response, identifies a visited wireless network on which the wireless device is likely to roam or is currently roaming. The outbound roaming system queries the visited wireless network to offer security information for the wireless device. The security information can include a security parameter for the visited wireless network to mitigate a potential cyberattack enabled by the wireless device. In response to receiving an acceptance of the offer and satisfying a condition, the outbound roaming system provides the security information to the visited wireless network. As such, the visited wireless network can dynamically defend against cyberattacks enabled by roaming devices.

Cybersecurity system for outbound roaming in a wireless telecommunications network

Described herein are techniques for facilitating communications between vehicles within a platoon while minimizing latency. In some embodiments, such techniques may be performed by a lead vehicle and may comprise obtaining, from one or more sensors, sensor information pertaining to an environment in which the lead vehicle is located and generating, from the sensor information, driving instructions to be executed by a platoon of vehicles. The techniques may further comprise identifying, within the platoon of vehicles, a plurality of separate groups of vehicles and transmitting the generated driving instructions to a platooning platform via a long-range communication channel such that the driving instructions are relayed to each of the plurality of separate groups of vehicles. The techniques may further comprise transmitting the generated driving instructions to at least one additional vehicle of the platoon of vehicles via a short-range communication channel.

Network assisted platooning for self driving vehicles

A telecommunication network associated with a wireless telecommunication provider can be configured to select RAN components for use by a UE in an open RAN. Hardware/software of a telecommunication network automatically selects one or more RUs, DUs, and CUs (which may come from different vendors) to use for a communication session with a UE. In some configurations, an application on the UE specifies the desired performance (e.g., bandwidth requirements, processing requirements, latency requirements, . . . ). For example, if an application requests a large throughput of data, a Massive MIMO RU can be selected for use, whereas if a moderate throughput is specified, then a traditional 4×4 antenna can be selected for the communication session. Similarly, if the network load is high, then multiple DUs can be activated by the telecommunication network to work together and provide necessary processing power.

Selection of open radio access network (RAN) components

Systems, methods, and computer-readable media herein dynamically adjust the policies used within a core network. These policies are determine based on the identification of a user device being a reduced capability device and the data requirements for that device. A correlation between the type of reduced capability device and the data requirements is used to derive data-drive insights using a near-real time RAN intelligence controller. The data used to determine these insights and policies are based near-real time sources.

Managing a baseband network policy

A method is performed by a wireless mobile network to mitigate interference between communication links. A request is received for resources needed to support an application by a vehicle relative to another vehicle. The resources are configured based on the application and are used to establish a direct communication link between the vehicles. The resources are to be shared between the direct communication link and another communication link. The mobile network defines certain blanked resources that are disallowed for use to perform the application. Any remaining resources (or non-blanked resources) are allowed for use to perform the application. The blanked resources can be used by the other communication link to avoid interference with the direct communication link. The allocation of resources is communicated to the vehicle to establish the direct communication link with the other vehicle.

Network-assisted blanking of shared resources for direct communication links

A method performed by a cybersecurity system that receives a registration request of a wireless device over a 5G network and, in response, selects a network slice associated with a capability, a traffic characteristic, and includes network resources. The system dynamically provisions security resources for multiple network slices based on respective security requirements, which are determined by monitoring network traffic associated with functions or applications supported by the network slices. The system allocates the selected network slice including security resources that satisfy its security requirement to support the wireless device.

An address retrieval system that retrieves the physical address of a user based on a request from another user. The address retrieval system can be connected to a network, such as a cellphone network, to allow a user to submit a request containing personally identifiable information, such as a phone number, of another user and the address retrieval system can locate/retrieve the requested address information and return the information to the requesting user or a third party. The release of the address information can be managed by a user-configurable privacy policy that provides rules, permissions and/or other management regarding the release of the user's address information.

Address retrieval systems and methods

A security system generates a digital signature for a small cell of a wireless network and assigns the digital signature to the small cell for connecting to the wireless network. The digital signature can be generated based on a connectivity schedule for the small cell. When the security system obtains a connection request from the small cell to connect to the wireless network, the security system compares an instance of the digital signature included in the connection request with an expected digital signature and compares the point in time when the connection request was communicated with an expected time indicated in the connectivity schedule. The security system detects an anomaly when the instance of the digital signature deviates from the expected digital signature or the point in time deviates from the expected time, and causes performance of an action based on a type or degree of the anomaly.

A system obtains security data of interconnected networks. The visibility of the security data is asymmetric for each interconnected network relative to the other. The security data is continuously stored and used in real-time or near real-time to identify services of the interconnected networks that require safeguards against a potential cyberattack. The interworking system determines a security parameter that relates the security data to the potential cyberattack and communicates the security parameter to the interconnected networks. The interconnected networks can safeguard against the potential cyberattack based on the security parameter.

Techniques for improving a vehicles access to GPS signals are discussed herein. An unmanned aerial vehicle (UAV) may be configured to communicate with the vehicle, such as a V2X capable vehicle, and provide GPS line of sight connection to a GPS satellite, thereby avoiding any blocking issues while maintaining accurate positioning of the vehicle on the ground. Short-range communications (e.g., Wi-Fi, PC5, unicast, etc.) may be used to provide the connectivity between the vehicle and the UAV. In some cases, a vehicle may drive into a designated area and the UAV and/or the vehicle may initiate connectivity with the other and start UAV assisted positioning services within the designated area.

Unmanned aerial vehicle assisted positioning

A fifth generation (5G) network can provide testing capabilities by employing a test server to generate requests for testing at remote locations of the 5G network. The test server can be used to initiate tests, determine test conditions for conducting the tests, direct test locations, and receive test data from test tools remote from the server. The test server can initiate, establish, maintain, format, or otherwise determine tests that are usable to improve operation of the 5G network.
