Abstract: A network node, a core network node and a user equipment are disclosed. The network and the core network node each includes a processor; and a memory storing respective instructions. When executed by the processor, the network node is configured to: determine at least one radio access network timing synchronization status reporting range associated with at least one radio access network timing synchronization status attribute; and transmit, to a second network node, the radio access network timing synchronization status reporting range. The core network node is configured to: determine at least one radio access network timing synchronization status reporting range associated with at least one radio access network timing synchronization status attribute. In addition, the user equipment includes a processor; and a memory storing instructions that, when executed by the processor, cause the user equipment to: determine a clock quality acceptance criteria; and transmit the clock quality acceptance criteria.

Abstract: To take into account a possible collision during sidelink communications, a transmitter (transceiver) may request one or more other apparatuses (transceivers, receivers) to monitor and report transmissions on sidelink resources at least during a resource received and used by the transmitter for transmission of the data. When one or more monitoring reports are received it is determined whether to reschedule the transmission of the data.

Abstract: Various communication systems may implement network management tools to help manage registration requests from a user equipment. For example, network functions in a communication system with a shared data layer may be used to manage requests from the user equipment. A method may include transmitting a request from a user equipment to a network function. The method may also include receiving at the user equipment a temporary identification from the network function The temporary identification comprises an identifier that helps locate a shared data layer function that stores context information for the user equipment. In addition, the method may include transmitting from the user equipment a subsequent request comprising the temporary identification to another network function or the network function.

Abstract: A method, apparatus and computer program product are provided in order to cause a redirection request to be provided by an access and mobility management function (AMF) to one or more access nodes to cause at least some of user equipment returning from an idle mode to be redirected from the AMF to an alternate AMF within a same AMF set. In response to a subsequent determination to stop redirection, the method, apparatus and computer program product also cause a cease redirection request to be provided by the AMF to one or more access nodes in order to stop redirection of user equipment returning from the idle mode to the alternate AMF.

Abstract: In some example embodiments, there is provided a method. The method may include generating, by a network node, a message including an indication of whether a bearer is at least one of a default bearer or a dedicated bearer; and sending, by the network node, the generated message, wherein the generated message is sent to a base station to enable the base station to control assignment of the bearer to a macrocell when the indication represents that the bearer is a default bearer. Related systems, methods, and articles of manufacture are also described.

Abstract: There are provided measures for enabling/realizing external steering of access traffic multipath communication in a mobile communication system, e.g. an external access traffic multipath communication steering function. Some such measures include that a session management function element or instance in a mobile communication system initiates control of establishment of at least one user plane session for access traffic multipath communication, obtains communication information of an external steering function element or instance to be used for steering access traffic multipath communication in the at least one user plane session, creates access traffic multipath communication rules, forwarding action rules and multi access rules for access traffic multipath communication in the at least one user plane session, and provides the access traffic multipath communication rules and the communication information of the external steering function element or instance to the communication function element or instance.
