According to some embodiments, a method performed by a network management system for managing one or more radio access networks (RANs) comprises receiving an indication from a RAN that a RAN identifier has been assigned for a wireless device, associating a management system identifier for the wireless device with the RAN identifier for the wireless device; and storing the association in a wireless device registry.

Individual user equipment management in RAN

An apparatus in a mobile communication network combines information from monitoring IP flows carrying latency sensitive content passing the apparatus and information about the application behavior and target Quality of Experience (QoE) or target connectivity characteristics such as Quality of Service (QoS) from the application to provide ongoing predictions of QoE/QoS. In some cases, the apparatus exploits a probe on a device to generate traffic for learning flow characteristics not obtained from monitoring application IP flows in the network. Embodiments disclosed herein can be used to predict quality metrics for many applications where jitter/latency is a factor affecting perceived quality, such as QoE for a human consumer or QoS for machine type communications. The embodiments are applicable to the analysis of traffic carrying conversational speech.

Estimating quality metric for latency sensitive traffic flows in communication networks

Systems and methods are disclosed herein for User Equipment (UE) assisted data collection for mobility prediction. In one embodiment, a method performed by a UE for UE-assisted data collection for mobility prediction comprises receiving, from a network node of a cellular communications system, a UE trajectory prediction model for predicting a UE trajectory. The method further comprises executing the UE trajectory prediction model to generate a predicted trajectory for the UE, comparing the actual UE trajectory to the predicted UE trajectory, and sending, to a network node of the cellular communications system, a result of the comparison of the actual UE trajectory to the predicted UE trajectory. In this manner, mobility prediction performance is improved.

UE-assisted data collection for mobility prediction

A method for over-the-top, OTT, management in a communication network is presented. The method is performed in a packet data network gateway, PGW. The method comprises receiving (S) a request for an application network interaction protocol, ANIP, service from an application client, sending (S) the received request to a global ANIP server, wherein the request is extended with a public land mobile network, PLMN, identity, receiving (S) an address to a local ANIP server from the global ANIP server, and sending (S) the received address to the local ANIP server to the Send request for application client. Methods, a PGW, an application client, an ANIP server, computer programs, and a ANIP service computer program product for OTT management in a communication network are also presented.

Over-the-top management in a communication network

Methods and systems for providing flexible information exposure in a Fifth Generation (5G) Core (5GC) and an Operations, Administration, and Maintenance (OAM) system are provided. According to one aspect of the present disclosure, a method, performed by a first network node of a 5GC for providing flexible information exposure in the 5GC and an OAM system, comprises: receiving, from a second network node, a request to register the second network node as a provider of data and/or a compute function; registering the second network node as a provider of the data and/or the compute function; storing information associating the second network node with the data and/or compute function provided by the second network node; and sending, to the second network node, a response to the request to register the second network node as a provider of data and/or a compute function.

Flexible data analytics processing and exposure in 5GC

A method performed by a core network node of a wireless communications network having a first gNB and a second gNB, a wireless device, WD, is connected to the first gNB, and a first Packet Data Unit, PDU, session is established between the WD and a Data Network over a first User Plane Function, UPF. The method includes obtaining information regarding a predicted positional change indicating a new future position of the WD and selecting a second UPF which is more suitable than the first UPF for transmission of data between an application server and the WD for the new future position. The method includes triggering establishment of the second PDU session over the second UPF, and in response to the triggering establishment of the second PDU session over the second UPF, triggering a first move of packet flows from the first PDU session to the second PDU session.

Method and apparatus for switching UPFs

A method for over-the-top (OTT) management in a communication network is presented. The method is performed in an application client. The method comprises sending a request for activation of a policy for an application network interaction protocol (ANIP) service to a packet data network gateway (PGW) wherein the request indicates an address to a local ANIP server; receiving a set of rules related to the requested activation of the policy from the PGW, wherein the set of rules are defined for a packet data network (PDN) session applicable for the ANIP service; and communicating over the communication network based on the received set of rules. Methods, application clients, PGWs, ANIP servers, computer programs, and a computer program for OTT management in a communication network are also presented.

A de-jitter function for holding-and-forwarding packets such that the packets are delivered with an agreed fixed latency. The de-jitter function can be placed at the edge of a virtual 5G TSN switch (e.g. the de-jitter function can be deployed as part of a UPF for uplink (UL) packets and/or it can be deployed as part of a user equipment (UE) for downlink (DL) packets). By using the de-jitter function, the TSN can consider the wireless network as having a consistent, deterministic latency with no jitter.

Communication system with de-jitter buffer for reducing jitter

A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

Resource segmentation to improve delivery performance

According to a yet further aspect of the embodiments of the present invention a serverconfigured to bind a device application to a web service is provided. The server comprises WebRTC functionality. The server is configured to receive a request for the web service from the device application, wherein communication between the server and the device application is done via https and WebRTC and the device application is configured to generate WebRTC credentials comprising a private key, certificate of the private key and a fingerprint of the certificate. The server is configured to receive the fingerprint and fingerprint generation algorithm of the certificate, store the fingerprint and fingerprint generation algorithm and associating the fingerprint with the device application, and use DTLS, providing the certificate of the device application, in combination with the stored fingerprint to identify the device application to bind the device application to the web service.

Methods and arrangements for binding a device application to a web service

Systems and methods that are particularly well-suited for service-based core network endpoint authentication are disclosed. In some embodiments, a method of operation of a network node implementing a second network function in a core network of a cellular communications system comprises receiving, at a main service of the second network function, a request from a first network function for a desired service via Hypertext Transfer Protocol/Representational State Transfer (HTTP/REST) signaling. The request comprises information that identifies one or more delegate endpoints of the first network function that expose one or more delegate services, respectively, of the first network function for providing the desired service using one or more different communication styles. The method further comprises initiating the desired service using a selected delegate endpoint from the one or more delegate endpoints identified by the information comprised in the request.
