摘要： Procedures, systems, and devices for addressing quality of service (QoS) during an intersystem change of a wireless transmit/receive unit (WTRU) are discussed herein. A WTRU may send a protocol data unit (PDU) modification request to a network node, such as a session management function (SMF) device, indicating support for reflective quality of services (RQoS). In response to the modification request, the WTRU may then receive an acknowledgement, after which the WTRU may then be able to send data for a PDU of a specific RQoS. The RQoS may be specific to a single PDU or a plurality of PDUs. The modification request may include Session Management (SM) and/or Mobility Management (MM) information. The modification request may be included in an attach procedure or a tracking area update (TAU).

摘要： A method and a system are disclosed for providing session continuity in a 5G system. A wireless transmit receive unit (WTRU) may receive, from a session management function (SMF), a first Non-Access Stratum (NAS) message indicating a Packet Data Unit (PDU) session re-establishment. Upon receiving the first NAS message, the WTRU may determine an old PDU session ID based on the NAS message and generate a new PDU session ID. The WTRU may transmit a second NAS message indicating a PDU session establishment request. The second NAS message may include the old and new PDU session IDs. Upon receiving the PDU session establishment request, the SMF may determine that the old PDU session ID is associated with an existing PDU session for which the PDU session re-establishment is requested. The SMF may also determine that the new PDU session ID is associated with a new PDU session to be established.

摘要： Coordinated P-GW change for SIPTO may be provided. A WTRU may send and/or receive one or more flows via a first PDN connection and via a first P-GW. The WTRU may send an indication to the network that at least one flow of the first PDN connection is available for SIPTO. The indication may include one or more SIPTO preferences. The WTRU may receive a message from a MME. The message may trigger establishment of a second PDN connection via a second P-GW. The WTRU may move, while maintaining the first PDN connection, the at least one flow from the first PDN connection to the second PDN connection. The WTRU may deactivate the first PDN connection when the one or more flows have been moved to the second PDN connection and/or when no information has been received via the first PDN connection after a predetermined duration.

摘要： A network may implement a method to support a mobility of a wireless transmit/receive unit (WTRU). The network or network functions may identify the WTRU that is associated with one or more capabilities and one or more mobility properties. The network or network functions may determine subscription information and network policy information for the WTRU. The network or network functions may select a mobility pattern for the WTRU based on the one or more capabilities and the one or more mobility properties associated with the WTRU, the subscription information, and the network policy information. The mobility pattern may be associated with a mobility parameter and a value corresponding to the mobility parameter.

摘要： Delivery mode switching between unicast and multicast/broadcast is described. A WTRU may move from a RAN node that supports multimedia broadcast/multicast service (MBMS) session to one that does not support MBMS session, or vice versa. In order to avoid duplicated packet transmission, the unicast delivery mode may be deactivated when the WTRU decides to use multi-cast/broadcast session. When the multicast/broadcast session is not available, the WTRU may re-activate the unicast delivery mode for MBMS. For example, the PDU session for unicast delivery mode deactivation may be released and the PDU session for unicast delivery mode reactivation may be re-established. Such activity may necessitate additional signaling between WTRU and the network for PDU session establishment/release and all other services running in the PDU session may be interrupted.

摘要： A method addressing handover procedure failure or cancellation includes receiving, by a remote wireless transmit/receive unit (WTRU) connected to a source NodeB, a handover command to begin a handover procedure to establish a connection with a target NodeB on a network. A method may further include, on a condition that the handover procedure fails, transmitting, by a relay TRU, a handover failure/cancellation indication to the remote WTRU and cancelling, by the remote WTRU, the handover procedure. A method may also include initiating, by the remote WTRU, a radio resource control (RRC) re-establishment procedure to connect with the source NodeB or a new NodeB.
