Described is a method of synchronizing a TSN NW-TT module inside a UPF with a Grandmaster (GM) in a Time Domain of the communication network. The method comprises receiving one or more PTP or gPTP messages on an N3 interface of the UPF. The method includes determining a first time offset value between the GM and the UPF N3 interface based on information received in the PTP or gPTP messages. A timing of the UPF N3 interface is adjusted using the determined first time offset value to synchronize the time between the UPF N3 interface and the GM. The method includes determining a second time offset value between the UPF N3 interface and the NW-TT module. A timing of the NW-TT module is adjusted using the determined second time offset value to synchronize the time between the NW-TT module and the GM.

Method of high precision time synchronization with a communication network grandmaster for user plane function

Provided is a method and system for controlling data transmission in a 5G-V2X network. The 5G-V2X network has at least one defined geographical area including a plurality of traffic sensing devices (TSDs). Each of the TSDs is configured to provide data over one or moreG channels to a V2X processing system via an edge gateway module (EGW) of the defined geographical area. The EGW includes a transmission controller (TC). The method comprises the TC dynamically adjusting a data transmission frequency of at least one TSD of the plurality of TSDs in accordance with a transmission control policy.

System and a method for increasing network efficiency in a 5G-V2X network

Described is a method of processing data packets in a communications network. The method comprises receiving a first data packet of a data packet flow from a network device and determining an instruction set for processing said first data packet. A flow key for said first data packet is determined. The first data packet is processed according to the determined instruction set. The method includes receiving a subsequent data packet and determining if a flow key of said subsequent data packet matches said flow key of said first data packet. If yes, the subsequent data packet is processed using the instruction set determined for said first data packet.
