Systems, methods, apparatuses, and computer program products for 5G support for time sensitive communication. One method may include sending a report of user equipment capabilities to a communication network. The method may also include receiving a propagation delay compensation configuration from a network node. The method may further include configuring a communication with the network node based on the propagation delay compensation configuration. Further, the propagation delay compensation configuration may take into consideration at least one of propagation delay compensation information from an application function or the report.

Application function influencing intra-5G propagation delay compensation

Systems, methods, apparatuses, and computer program products for working clock determination for a mobile user equipment. A method may include receiving time domain information at a session management function during a protocol data unit (PDU) session procedure. The method may also include forwarding the time domain information to a user plane function for the PDU session procedure. The method may further include configuring the user plane function according to the time domain information to enable determination of a correct mapping between the time domain information and a user equipment or a PDU session.

Working clock determination for a mobile user equipment

Method, apparatuses, and computer program products provide means for monitoring time sources for nodes of a network and providing timing resiliency solutions. An example method includes: establishing time synchronization within a network comprising a plurality of nodes using a time source; receiving an indication regarding at least one of degradation or failure of the time source for at least one node; receiving an indication regarding at least recovery of the time source for the at least one node; and determining, within the network, an action to be taken to upon failure at the at least one node in response to the at least one of the degradation or the failure of the time source for the at least one node, where the action to be taken comprises instructing the at least one node to leverage either hold over functionality or a backup time source.

Time source health monitoring support for network timing resiliency

An apparatus including at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to receive, from a serving access node, a downlink radio resource control message including reference time information for a clock provided by the serving access node and traceability information for enabling traceability of the clock to a reference time standard. The traceability information includes at least information on a clock class indicative of a current status of the clock provided by the serving access node.

UTC traceability support for terminal devices

Device-side, translator functions may be authenticated by elements of a 5G core network before communications involving such functions are allowed to occur, or continue to occur.

Systems and methods for authenticating time-sensitive network elements

According to an example aspect of the present invention, there is provided a method comprising: receiving, from a network node, before entering a power saving state, an indication of a dependency between frequencies and time instances; identifying at least one frequency based on the indicated dependency and a moment of time; and selecting a cell utilizing the identified at least one frequency.

Carrier selection in wireless network

A method, apparatus and computer program product are provided herein to receive, from a source, performance requirements, and cause transmission, to a network, of a request to influence time sensitive communications (TSC) configuration parameters. For example, a method is provided to in response to the request to influence TSC configuration, receive, from the network, network configuration and radio access network (RAN) resource constraints and determine a quality of service (QoS) and the TSC configuration parameters to support a TSC data stream based on the performance requirements received from the source, the network configuration, and the RAN resource constraints. The method is further configured to cause transmission of the determined QoS and the TSC configuration parameters to the network and the source and in an instance the network accepts the determined QoS and the TSC configuration parameters, configure resources for the TSC data stream and continuously support service continuity.
