Abstract: A method, apparatus and computer program product may be provided for providing always-on as an attribute of a PDU session, providing interworking aspects with respect to an always-on PDU session, and enabling network determination of whether a PDU session will be an always-on PDU session. An example method may include receiving, from UE, a PDU session establishment request message, the PDU session establishment request message comprising an always-on PDU session requested IE set to a value indicative of a request to establish a new-always on PDU session (e.g., “Always-on PDU session requested”), and upon a determination that the requested PDU session shall be established as an always-on PDU session, cause transmission of a PDU session establishment accept message, the PDU session establishment accept message comprising an always-on PDU session indication IE that is set to a value indicative of always-on PDU session required (“Always-on PDU session required”).

Abstract: Systems, methods, apparatuses, and computer program products for efficient registration for partially supported service areas are provided. One method may include providing, to at least one user equipment registered to a network within a registration area, information comprising one or more lists of single network slice selection assistance information (S-NSSAIs) and one or more lists of tracking area identities (TAIs). The one or more single network slice selection assistance information (S-NSSAIs) is included in a list of rejected single network slice selection assistance information (S-NSSAIs) or in a list of extended rejected single network slice selection assistance information (S-NSSAIs), and is associated with a cause value indicating that the one or more single network slice selection assistance information (S-NSSAIs) is not supported uniformly in the registration area and is not supported in a current tracking area.

Abstract: A method, apparatus, and computer program product provide for controlling access attempts for wireless backhaul. In the context of a method, the method constructs an access request comprising an Integrated Access and Backhaul (IAB) access indication. The method further determines whether the access attempt is allowed for a particular cell, and if so, determines an establishment cause value based at least on the IAB access indication. The method also causes transmission of the access request and establishment cause value.

Abstract: Methods, systems, apparatuses, and computer program products are provided for managing configuration of ports of an entity in a device or a mobile communication system, and to facilitate integration of the device and the mobile communication system with a time sensitive networking (TSN) network. A feature support information element may be set to indicate whether per-instance parameter handling of a stream filter instance table is supported by an entity, such as a TT including a device side TSN translator (DS-TT)/network side (NW-TT), and/or network function such as a TSN application function (TSN AF). Accordingly, a stream filter instance value for at least one, or each, stream filter instance of a stream filter instance table may be populated by a TT or TSN AF and sent to the other of the TT or TSN AF.

Abstract: In some example embodiments, there may be provided a method that includes receiving, at a user equipment while being served by a first system and during protocol data unit session establishment or modification procedure, a message including an access point name aggregate maximum bit rate value; and when there is an inter-system change from the first system to the second system, setting, at the user equipment, the access point name aggregate maximum bit rate value of a session management context for the second system to the received access point name aggregate maximum bit rate value received while being served by the first system. Related systems, methods, and articles of manufacture are also described.
