Abstract: A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.

Abstract: A method is provided to anonymize the media access control (MAC) address of a client device. The method involves generating a plurality of media access control (MAC) addresses for use by a client device in a network. Policies are defined that determine which one of the plurality of MAC addresses is to be used by the client device. The plurality of MAC addresses allocated for use by the client device are registered with a management entity in the network.

Abstract: In one example, a Network Policy Function (NPF) obtains a first identifier for a User Equipment (UE) based on communications between the UE and a first access network of a system, and an Internet Protocol (IP) address used by the UE to communicate over the first access network. The NPF obtains a second identifier for the UE based on communications between the UE and a second access network of the system. The NPF determines that the UE used the IP address to communicate over the first access network of the system based on a correlation between the first identifier for the UE and the second identifier for the UE. The NPF provides the IP address to the UE, and the UE uses the IP address to communicate over the second access network.

Abstract: An Evolved Node B (eNB) provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The eNB determines that the eNB is connected to at least one gateway that provides public internet access, and broadcasts an internet indication in a predetermined System Information Block (SIB). The eNB receives an attach request from the UE including an attach type of internet enabled and a Packet Data Network (PDN) type of internet enabled. The eNB forwards the attach request to a Mobility Management Entity (MME).

Abstract: Methods are provided which indicate availability of the same service on a different access network. In these methods, the network controller generates an identifier for each of one or more services provided by a wireless local access network (WLAN). The identifier is associated with a particular service which is also provided by a private radio network. The network controller provides to an access point the identifier to be broadcast to one or more user devices of the WLAN to connect to the particular service via the private radio network. A mobility management entity receives a request from a user device to connect to the private network, where the request includes an identifier associated with a particular service provided to the user device in the WLAN and based on the identifier, the mobility management entity enables the particular service to be provided to the user device via the private radio network.

Abstract: Dynamic roaming partner prioritization based on service quality feedback may be provided. First, a server associated with an enterprise may receive performance data and location data for each of a plurality of service provider networks from a plurality of end use devices associated with the enterprise. Next, the server may assign a ranking to a plurality of service providers by location based upon information. The information may comprise the received performance data and the location data corresponding to each of the plurality of service provider networks. The server may then push the ranking to a first end use device.

Abstract: In one example, an authentication server generates a Chargeable User Identity (CUI) for a User Equipment (UE) based on a first indication of an identifier obtained from the UE based on communications of the UE over a first network interface of a system. The authentication server obtains a second indication of the identifier based on communications of the UE over a second network interface of the system. In response to obtaining the second indication of the identifier, the authentication server determines that the UE is attempting to communicate over the second network interface. In response to determining that the UE is attempting to communicate over the second network interface, the authentication server uses the CUI for further communications of the UE over the second network interface.
