A service is utilized by a wireless communication device (). For this service, the wireless communication device () simultaneously maintains a first data path () and a second data path () to a wireless communication network. The first data path () has a first QoS level, and the second data path () has a second QoS level that is different from the first QoS level. The wireless communication device () selects one of the first data path () and the second data path () for transmitting content of the service while the other of the first data path () and the second data path () is maintained in an inactive state.

Simultaneous data paths for QOS control of service data traffic

Methods of operating a first VAE server are disclosed. V2X message information per geographical area is received from a V2X application specific server. Position information is received from a VAE client of a wireless device, wherein the position information indicates a position of the wireless device. Responsive to receiving the position information and responsive to the V2X message information per geographical area, a second VAE server is identified based on the position information. An address for the second VAE server is transmitted to the VAE client of the wireless device. Related VAE servers and V2X wireless devices are also discussed.

Methods of identifying VAE servers and related V2X wireless devices and servers

A V2X UE (e.g., wireless device) that includes a vehicle-to-everything (V2X) application enabler (VAE) client and a V2X application-specific client associated with a V2X application, where the V2X UE is connected with a V2X application server is enabled to receive notifications of conditions occurring in a wireless network that connects them. The V2X application-specific client in the UE performing a registration with the V2X application server for receiving notifications. The registration comprises one or more conditions monitored by a network function (NF) in the wireless network. For example, the condition can be related to QoS provided by the network in a particular geographic area and/or in a particular time window, where the NF can be a network data and analytics function (NWDAF). The VAE client receives from the VAE server the notifications. The VAE client can receive a notification of a particular occurrence of the condition after the NF monitoring detects the occurrence.

Network information delivery towards application at device side

A method performed by a network node for a wireless telecommunications network performs operations including providing a resource allocation model that corresponds to a base station and that provides a recommendation regarding resource allocation for a user equipment, UE, that is in an operating zone of the base station during a limited resource condition of the base station. Operations may include identifying, based on the resource allocation model, a reduced priority zone in the operating zone of the base station that corresponds to the UE having a high risk of reduced service from the base station relative to other UEs in the operating range of the base station.

Methods for intelligent resource allocation based on throttling of user equipment traffic and related apparatus

Embodiments include methods performed by a V2X application enabler (VAE) client of a V2X User Equipment (UE) arranged for communication with a VAE server. Such methods include sending, to the VAE server, a registration or de-registration request to register or de-register for receiving intelligent transport system (ITS) messages. The registration or de-registration request includes an identifier of the V2X UE and an identifier of a first type of ITS messages from the VAE server, for which the V2X UE wishes to register or de-register for receiving. Such methods include receiving, from the VAE server a response indicating acknowledgement of the registration or de-registration request. Other embodiments include complementary methods performed by VAE servers, as well as UEs and application servers configured to perform such methods.

Method, apparatus, and computer-readable medium for intelligent transportation system (ITS) message distribution

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

Network architecture, methods, and devices for a wireless communications network

A method of operating a vehicle to anything, V2X, application enabler, VAE, server is provided according to some embodiments disclosed herein. The method includes receiving a registration request message from a V2X application specific server. The method further includes transmitting a registration response message to the V2X application specific server responsive to receiving the registration request message.

Methods providing V2X application server registration

The invention relates to a method for grouping a plurality of user entities connected to a cellular network into different clusters, the method comprising: —collecting, for each of the plurality of user entities, activity information comprising different activity parameters, each activity parameter describing an activity of the corresponding user entities in the cellular network, —generating, for each of the plurality of user entities, a user profile comprising the activity parameters for the corresponding user entity, —grouping the plurality of user entities into the different clusters based on a similarity of the activity parameters of the user profiles.

Clustering of user entities in a cellular network

Embodiments include methods performed by a V2X application enabler (VAE) client, of a V2X User Equipment (UE) arranged for communication with a VAE server. Such methods include sending, to the VAE server, a first request for registration or de-registration to receive intelligent transportation system (ITS) messages associated with at least one of the following: a first V2X service, when an identifier of the first V2X service is included in the first request; and a first geographic area, when an identifier of the first geographic area is included in the first request. Such methods also include receiving, from the VAE server, a first response comprising an acknowledgement of the first request for registration or de-registration. Embodiments also include complementary methods and/or procedures performed by VAE servers, as well as V2X UEs, VAE servers, and computer-readable media configured in accordance with the exemplary methods and/or procedures.

A method performed by a vehicle to everything application enabler (VAE) client of a wireless device for using a service in a wireless communication network for vehicle to anything (V2X) wireless devices. The VAE client receives, from a V2X application specific client, a V2X message of a service with a service ID; and determines a network node for receiving an uplink V2X message based on the service ID. The VAE client further transmits the uplink V2X message to the determined network node with the service ID.
