Method for Configuring Data Sessions For a User Equipment
The present disclosure relates to method performed by a control node (SMF) configured to configure data sessions for a user equipment, UE, wherein at least one first data session is established by a first User Plane Function, UPF, node (UPF1) and the first data session (DS1) is connected via a first wireless access node (gNB_Source) associated to a first geographical area (UPF_area1) of the first UPF node (UPF1), the method comprising receiving, from a service node (NWDAF), a first notification (508) of predicted geographical area mobility of the UE, the first notification (508) being directly or indirectly indicative of a plurality of predicted target wireless access nodes (WN3, WN4) indicated as potential target access nodes for the UE, processing the first notification (509), and determining if connecting the UE to any one of the plurality of predicted target wireless access nodes (WN3, WN4) comprises a change to an associated geographical area (UPF_area2) different to the first geographical area (UPF_area1), transmitting, to the first wireless access node (gNB_Source), a data session modification request (512) comprising the processed first notification, the data session modification request being indicative of a request to transfer the at least one first data session (DS1) to any one of the plurality of predicted target wireless access nodes (WN3, WN4), receiving, from the first wireless access node (gNB_Source), a data session establishment response (516) comprising a selected wireless access node (gNB_Target) of the plurality of predicted target wireless access nodes, the selected wireless access node (gNB_Target) being associated to a second geographical area (UPF_area2), configuring at least one second data session (DS2), to be connected via the selected wireless access node (gNB_Target), by sending, to a second User Plane Function, UPF node (UPF2) serving the second geographical area (UPF_area2), a data session establishment request (518), receiving, from the selected wireless access node (gNB_Target), a second notification (530) indicative of a transfer of the UE from the first wireless access node (gNB_Source) to the selected wireless access node (gNB_Target), and releasing (534) the first data session (DS1).
WIRELESS CLIENT DEVICE DETECTION AND STEERING ON A NETWORK WITH MULTIPLE ACCESS POINTS
A method for automatic steering of client devices accessing a network to a different access point on the network is provided. A network controller of the network device automatically identifies a pre-determined type of electronic client device gaining access to the network and automatically designates the client device as non-steerable when identified as the predetermined type of electronic client device. Thus, when the network controller selects a client device for being steered to a different access point of the network during a steering event, client devices designated as non-steerable by the network controller are prevented from being steered and only client devices that are not designated as non-steerable are available as candidates to be steered. A network device is also provided.
MME based handover decision
Techniques are described herein for handling handover requests from a user device. The techniques include receiving a handover request from a user device connected to a first access network and identifying an evolved packet data gateway (ePDG) serving the user device. The user device provides to the ePDG, measurement reports indicating network conditions. The techniques further include receiving the measurement report from the ePDG and determining whether a measurement in the measurement report is above a predetermined threshold. If the measurement is above the predetermined threshold, the handover request is accepted to enable the user device to connect to a second access network.
UE and communication method therefor
A User Equipment (UE) includes: a transmitter configured to transmit, in a case that a timer is running for a piece of Single Network Slice Selection Assistance Information (S-NSSAI) at a time when a Public Land Mobile Network (PLMN) is changed, a Protocol Data Unit (PDU) session establishment request message for an identical piece of S-NSSAI in a changed PLMN without stopping the timer. This configuration allows for provision of a communication control method for the terminal to apply congestion managements expected by the network to the congestion managements applied by the network in 5G congestion management to which multiple congestion managements are applied.
SYSTEM AND METHOD FOR CONNECTION AND HAND-OVER MANAGEMENT ACROSS NETWORKS AND SSIDS
Systems, methods, and devices for steering an IEEE 802.11 station (STA) using a cloud server are disclosed herein. There may be a plurality of IEEE 802.11 access points (AP)s, where at least one AP of the plurality of APs operate at least a first virtual network. One or more APs of the plurality of APs may run a Client Steering Daemon (CSD) configured to perform unassociated STA monitoring that produces a log of data that may be sent to the cloud server on a regular or dynamic basis. The cloud server may receive the log data and transmit a signal to at least one of the APs of the plurality of APs to enable it to steer the STA between the first virtual network and a second virtual network.
AMF BASED HANDOVER DECISION
The techniques include receiving a handover request from a user device connected to a first access network and identifying a Non-3GPP Interworking Function (N3IWF) serving the user device. The user device provides to the N3IWF, measurement report indicating network conditions. The techniques further include receiving the measurement report from the N3IWF and determining whether a measurement in the measurement report is above a predetermined threshold. If the measurement is above the predetermined threshold, the handover request is accepted to enable the user device to connect to a second access network.
Optimizations to support enhanced handover procedures
Aspects of the present disclosure relate to wireless communications, and more particularly, techniques that may help optimize enhanced handover procedures, such as MBB and CHO handover procedures.
Methods, apparatus, and systems using enhanced dedicated core network (DCN) selection
Methods, apparatus and systems using Enhanced Dedicated Core Network (DCN) selection are disclosed. One representative method includes receiving, by the core network entity from another core network entity, information indicating that a DCN type is new or has change for a wireless transmit/receive unit (WTRU); and sending a message, by the core network entity to the WTRU, including a new or a changed DCN type.
Systems and methods for supporting fixed tracking areas and fixed cells for mobile satellite wireless access
Access, mobility management and regulatory services are supported for satellite access to a 5G core network. A coverage area, e.g., a country or region, is divided into fixed virtual cells and fixed tracking areas. The UE receives configuration information for fixed cells and fixed tracking areas associated with a serving PLMN. The fixed cells and the fixed tracking areas are defined, independently of each other, as fixed geographic areas. A position of the UE is used to determine a fixed serving cell and/or fixed tracking area for the UE. A service operation for the UE is enabled for the serving PLMN based on the fixed serving cell or the fixed tracking area. A fixed cell may be associated with an overlapping fixed tracking area by assigning a color code to the tracking area and appending the color code to an ID for the fixed cell.
DETECTING HANDOVER FAILURES AT AN ACCESS POINT
The present disclosure describes methods and apparatus for detecting handover failures at an AP when the AP does not have an X2 interface with at least one of its neighbors. For example, methods are provided for detecting handover failures at an AP based on at least on a UE context release command message received from a mobile management entity (MME) and/or determining that a radio resource control (RRC) connection reconfiguration (RCR) message is not delivered to the UE.
