Abstract: Systems, methods, apparatuses, and computer program products for handover optimization using time sensitive communication assistance information. The method may include, receiving, from a network element, a handover request message or a context message. At least one of the handover request message or the context message may include time sensitive communication assistance information. The method may also include at least one of performing an admission control procedure based on the time sensitive communication assistance information, and scheduling data transmission with a user equipment based on the time sensitive communication assistance information.

Abstract: A method and apparatus may include receiving, by a radio access network (RAN), at least one burst arrival time (BAT) parameter from at least one session management function (SMF). The method may further include determining, by the RAN, if at least one actual BAT is offset from the at least one received BAT parameter by at least one threshold. The method may further include setting, by the RAN, at least one BAT correction parameter based upon at least one offset time. The method may further include calculating, by the RAN, at least one new BAT parameter according to the one BAT correction parameter. The method may further include adjusting, by the RAN, at least one burst schedule based upon one or more of the at least one BAT correction parameter or the at least one new BAT parameter.

Abstract: Methods and apparatus, including computer program products, are provided for supporting network functions. In some example embodiments, there may be provided a method that includes selecting, by a network node, a network function instance and/or a group of network function instances, the selecting based on information indicating membership of the network function instance in the group of network functions instances and the information including session information for a request associated with a session of a user equipment, the session information indicating whether the network function instance and/or the group of network function instances is assigned to the user equipment; and forwarding, by the network node, the request to the selected network function instance and/or the selected group. Related systems, methods, and articles of manufacture are also described.

Abstract: In some example embodiments, there may be provided a method that includes generating, by an application function and based on a time sensitive communication requirement for one or more end stations, at least one quality of service parameter for a time sensitive communication path from a talker end station through at least a portion of a 5G system to a listener end station; and sending, by the application function, a request towards a policy control function, the request including the at least one quality of service parameter configured to enable a creation, at the one or more 5G nodes, of a quality of service flow in accordance with the at least one quality of service parameter, wherein the one or more 5G nodes comprise a user plane function and/or at least one base station. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: 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.

Abstract: Methods and apparatus, including computer program products, are provided for reliability network slicing. In some example embodiments, there may be provided a method that includes accessing, by at least one user equipment, a first network reliability slice served by a first base station; accessing, by at least one user equipment, a second network reliability slice served by a second base station, wherein the first network reliability slice and the second network reliability slice are established across domains such that one or more first resources providing the first network reliability slice are not shared with one or more second resources providing the second network reliability slice; establishing, by the at least one user equipment, a first packet data protocol session over the first network reliability slice and a second packet data protocol session over the second network reliability slice; and transmitting, by the at least one user equipment, user plane traffic over the first packet data protocol session on the first network reliability slice and duplicated user plane traffic over the second packet data protocol session on the second network reliability slice. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: Various communication systems may benefit from improved network communication setup. A method, in certain embodiments, may include determining at a network entity a new protocol data unit session anchor of a protocol data unit session with a user equipment. The method may also include transmitting from the network entity to the new protocol data unit session anchor a request to establish the new protocol data unit session anchor. In addition, the method may include transmitting an indication from the network entity to a radio access network. The indication may notify the radio access network to switch paths to the new protocol data unit session anchor. Further, the method includes sending from the network entity a gratuitous address resolution protocol request to the determined new packet data unit session anchor. The gratuitous address resolution protocol request may comprise an address of the user equipment in the protocol data unit session.

Abstract: A method for admission control including transmitting a first admission request to a distributed unit of the IAB donor, wherein the first admission request includes information about a resource set to be established for a terminal device; receiving a first admission response from the distributed unit indicating whether one or more resources in the resource set are to be accepted; transmitting a second admission request to each of at least one IAB node including information about the resource set; receiving a second admission response from each of the at least one IAB node indicating whether one or more resources in the resource set are to be accepted; and in response to determining that at least one resource in the resource set is to be accepted, transmitting to an IAB node serving the terminal device a request for establishing a context of the terminal device including information about the resource.
