Abstract: Systems and methods provide a short data, low latency service using a Multi-access Edge Computing (MEC) network. A network device receives, in a core network, an attach request from an end device and detect whether a packet size range for data transmissions from the end device is within a configured size threshold. The network device directs, when the packet size is within the configured size threshold, routing of the data transmissions via a control plane function of an edge network to a local instance of an application server in the edge network. The network device directs, when the packet size is over the configured size threshold, routing of the data transmissions via a user plane function of the edge network to a local instance of an application server in the edge network.

Abstract: Methods and apparatuses exemplified in this disclosure provide mechanisms for a wireless communication device to indicate its Radio Access Technology (RAT) preferences to a wireless communication network, and for a wireless communication network to consider the RAT preferences of a given device when deciding which RAT the device will use. As a non-limiting example of the advantages flowing from these mechanisms, devices operating within a network that includes or is associated with multiple RATs can indicate their preferences for which RAT they use, while still allowing the network to retain control of the RAT selection decisions. Such flexibility offers significant advantages in 5G networks that provide tight integration between multiple RATS—e.g., between LTE and NR air interfaces. However, the methods and apparatuses disclosed herein are not limited to 5G networks.

Abstract: Systems and methods can support identifying pairings and channel parameters in short-range wireless communications such as bluetooth low energy interfaces. Radio frequency sensors may be positioned within an electromagnetic environment where a master wireless device and a slave wireless device share short-range wireless communications. Signals transmitted between the master wireless device and the slave wireless device can be received by the radio frequency sensors. Inter-arrival times for packets within the received signals may be identified. Statistics of the inter-arrival times can be analyzed to identify connection intervals between the master wireless device and the slave wireless device as well as back-to-back interval exchanged within the connection intervals. Packet header contents may be used to reconcile the estimated timing parameters and time slots. Pairings between the master wireless device and the slave wireless device may be identified and tracked along with communication channel parameters.

Abstract: A switch has a determining section and a memory managing section. The determining section determines whether or not the node is in a non-ordinary state in which received packets cannot be successfully processed, on a basis of a determination whether or not congestion notification packets received from a node have been continuously received during at least a given period and a determination whether or not a quantity of memory used in a buffer memory which accumulates received packets is at least a given value. The memory managing section deletes, in a case where the node is determined to be in the non-ordinary state, data addressed to the node in the non-ordinary state among data accumulated in the buffer memory.

Abstract: A two-tier Anycast addressing hierarchy enables deterministic traffic management in an Anycast system. Different locations of the Anycast system advertise a common Anycast cover route comprising a first-tier Anycast address with a first address prefix, and different specific routes comprising a set of second-tier Anycast addresses with a second address prefix, wherein each address of the set of second-tier Anycast addresses falls within the already advertised Anycast cover route, and wherein the second prefix is larger than the first prefix. Domain Name System (DNS) operation can resolve queries to the cover route when normal Anycast operation is desired or can be modified to resolve a subset of queries to a particular second-tier address in order to shift a deterministic amount of traffic based on the resolved subset of queries to a deterministically selected Anycast system location based on the location from which the particular second-tier address is advertised.

Abstract: The present application relates to a method for detecting and determining a failure probability (pA) of a radio network. The method is characterized in that devices of the radio network cyclically transmit operating parameters to a central computer wherein each transmitted operating parameter comprises an operating value of the respective device and a detection time point (t) of the operating value. All transmitted parameters and values can be viewed at any time by accessing the central computer. The central computer cyclically stores the operating values of all operating parameters detected within a predefined time interval (T) as the respective operating constellation and checks the radio network for a failure (A). The central computer cyclically creates a model based on the stored operating constellations and failures (A), which assigns a failure probability (pA) to each possible operating constellation.
