A method of predicting a location of a user equipment, UE, in a mobile communication network includes generating a list of potential target base stations by generating a transition count for each potential target base station including a count of transitions from the base station to the potential target base station within a predetermined time period, generating a plurality of relative transition frequencies based on the transition counts, and generating a transition probability for each respective potential target base station based on the relative transition frequency of the potential target base station from the base station.

User equipment tracking and paging area selection in wireless communication systems

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 method and a platoon manager for enabling a first wireless device located in a first vehicle to communicate over a cellular network when the first wireless device has no connection to the cellular network. After identifying a vehicle platoon to which the first vehicle belongs, a relay vehicle is found in the vehicle platoon where a second wireless device is located that has a connection to the cellular network. The second wireless device is then instructed to act as a relay to the cellular network for the communication with the first wireless device by means of a wireless Device-to-Device (D2D) link between the first and second wireless devices.

A method and a vehicle as well as a method and a user equipment for enabling a network node to manage paging of the user equipment are disclosed. Moreover, a method and a network node for managing paging of a user equipment are disclosed. The user equipment sends, to the vehicle, an identification of the user equipment by use of a direct wireless communication connection. Then, the vehicle sends, to the network node, the identification of the user equipment. The network node sends, to the user equipment, a control message instructing the user equipment to apply a second DRX cycle, wherein the second DRX cycle is longer than a first DRX cycle. The network node also receives, from the vehicle, position information of the vehicle, whereby the network node, upon paging of the user equipment, sends a paging message, based on the position information of the vehicle, to the user equipment. Corresponding computer programs and carriers therefor are also disclosed.

Methods and vehicle, network node and user equipment for enabling efficient paging

A method in a network node downloads an upcoming web page to a user equipment. The network node obtains a first value, relating to the upcoming web page, of a set of features. The features represent any one out of: the upcoming web page, the user equipment, and a web browser in the user equipment. The network node predicts whether it is beneficial regarding download time to activate an uplink grant pre-allocation for the user equipment for downloading the upcoming web page. The prediction is based on a relationship between the first value and of a second value of the set of features, which second value is related to a previously downloaded web page, and an evaluation whether it is beneficial regarding download time to activate the uplink grant pre-allocation for the previously downloaded web page. The network node provides the prediction to a base station.

Network node, a base station for uplink grant pre-allocation

A method of operating a User Equipment, UE, in a wireless communication network. The UE is configured for Discontinuous Reception, DRX, operation with a DRX cycle having a DRX ON period in which the UE is in a DRX awake state and ready for reception and a DRX OFF period in which the UE is in a DRX sleep state. The UE determines whether an uplink packet to be transmitted is delay tolerant. The UE delays, when the uplink packet is regarded as delay tolerant, a request for an uplink transmission grant for the uplink packet until a DRX ON period of the UE. By delaying the request for an uplink transmission grant for a delay tolerant uplink packet until a DRX ON period of the UE, the UE does not have to wake up to listen to the response from the network during the DRX OFF period.

Efficient operation of user equipment in a wireless communication network

A method and apparatus for automatically adapting a service level for a service consumed by a terminal user in a communication network, using a service level control system (). A service usage analyzer () collects information on service usage of the user, and estimates the user with respect to his/her service usage based on features of a usage pattern extracted from the collected service usage information. A subscription policy manager () then adapts the service level for service usage based on the user estimation, by adjusting or introducing a corresponding rule or policy in the user's subscription profile (). The user will then consume the service with the new adapted service level.

A pre-scheduling grant transmission method performed by a network node includes issuing a first sequence of pre-scheduling grants to provide a UE with reserved resources for uplink data packet transmission from a send buffer of the UE, collecting data relating to at least transmitted uplink traffic initiated by the first pre-scheduling grants to obtain a data set providing a statistical description of the traffic flow during the time period covered by the first sequence of pre-scheduling grants, predicting from the obtained data set the time when the next data packet arrives to the send buffer of the UE, and transmitting at least one pre-scheduling grant to the UE at a time in the vicinity of the predicted time, thereby providing the UE with timely resources for transmitting the data packet shortly after the packet has arrived at the UE send buffer.
