A method performed by a Radio Area Network, RAN, function node for handling connectivity in a RAN is provided. The RAN function node receives from a network node, a first subscription request for one or more RAN insights relating to the connectivity, requested for an application related to a wireless device. The RAN function node identifies RAN data needed to fulfil the subscription request and sends to a RAN node, a second subscription request for the identified RAN data. The RAN function node receives published RAN data according to the second subscription request and generates the RAN insights according to the first subscription request based on the received RAN data. The RAN function node establishes which domain out of a trusted domain or an untrusted domain the generated RAN insights are to be exposed in and publishes the generated RAN insights according to the first subscription request.

Method and system for exposing radio access network (RAN) data

A fault tolerance solution for a multi-layer cloud system. The embodiments of this disclosure are applicable to radio access network (RAN) application area as well as cloud environment with virtual machine or container-based application function implementation. In one aspect there is a method performed by a load balancing system, which method includes: receiving a request sent by a client and selecting from a first cluster of serving entities a first main serving entity and a first backup serving entity. The method also includes, as a result of receiving the request sent by the client, sending to the client information identifying the selected first main serving entity and the selected first backup serving entity.

Load balancing systems and methods

A wireless device () is configured for dual mode V2X communications over multiple short range radio interfaces. The wireless device () is configured to transmit ITS messages over a first short range radio interface configured to operate according to a first communication standard (e.g. PC5 or IEEE 802.11p), and to receive ITS messages over both the first short range radio interface and a second short radio interface configured to operate according to a second communication standard. Implementing the transmitter chain of only one technology, either PC5 or IEEE 802.11p, at each wireless device () reduces complexity and mitigates co-channel and adjacent channel interference that is caused by uncoordinated and concurrent transmissions of different technologies from the same wireless device. Implementing receiver chains for both PC5 and 802.11p allows the wireless device () to receive signals in the ITS frequency band regardless of which technology the transmitting device is using.

A method performed by a network node to change a transport path for a user plane session in a radio communications network. The path prolongs along a first part between an antenna endpoint of a network node and a Packet Processing Function (PPF) instance serving the network node and a second part between the PPF instance and a Core Network (CN) endpoint. The network node identifies available CN endpoints in a CN, available PPF instances in a Radio Access Network (RAN) and of available antenna endpoints in the RAN that are available for the user plane session and comprises a number of possible transport paths for the user plane session. When detecting a change event related to the user plane session, the network node controls whether or not to change the transport path to any of the a number of possible transport paths for the user plane session.

A method and apparatus for requesting service delivery of data in a communication network. A mobile device sends, to an interaction device, information relating to a service and requests information relating to a RAN to which the mobile device is attached. It receives the requested information from a remote device and uses the received information to establish a required service delivery parameter relating to delivery of the service from a server to the mobile device. It sends towards the server a request for data, the request including the established service delivery parameter, and receives from the server data sent using the service delivery parameter.
