Abstract: A method performed by a network node for transferring Protocol Data Unit (PDU) sessions of a User Equipment (UE) during a mobility procedure in which the UE is moved from a Fifth Generation System (5GS) to an Evolved Packet System (EPS) is disclosed. The method comprises one or more of determining that a target Mobility Management Entity (MME) for the mobility procedure in the EPS supports a first number of EPS Bearers that is less than a second number of EPS Bearer Identities (EBIs) assigned to a number of PDU sessions (e.g., and their associated Quality of Service (QoS) Flows) of the UE that are to be transferred from the 5GS to the EPS; determining which of the PDU sessions and/or QoS Flows of the UE are not to be transferred to the target MME; and releasing, requesting the release of or initiating release of the PDU sessions and/or QoS Flows that are not to be transferred to the target MME.

Abstract: A wireless communication network (100) serves User Equipment (UEs) (101) over wireless network slices (111 – 113) that comprise Network Exposure Functions (NEFs) (141 – 143). The egress AF (134 – 136) receives a slice request from an external data system (102) and transfers the slice request to the NEF (141 – 143) in the wireless network slice (111 – 113). An Access and Mobility Management Function (AMF) (120) selects the wireless network slice (111 – 113) for the UE (101). The UPF (121 – 123) in the wireless network slice (111 – 113) receives user data from the UE (101) and transfers the user data to the ingress AF (131 – 133) in the wireless network slice (111 – 113). The ingress AF (131 – 133) transfers the user data to the NEF (141 – 143) in the wireless network slice (111 – 113). The NEF (141 – 143) transfers the user data to the egress AF (134 – 136) in response to the slice request. The egress AF (134 – 136) transfers the user data to the external data system (102) in response to the slice request.

Abstract: A network node (1700) configured to operate as a source network node (32) of a reconfiguration procedure transmits signaling to a target network node (34) of the reconfiguration procedure. The signaling indicates (i) whether or not the target network node (34) is to provide feedback information (44) to the source network node (32) and/or (ii) which one or more types of feedback information (44) the target network node (34) is to provide to the source network node (32). Based on the received feedback information (44), the network node may train a model to predict predicted information, predict the predicted information using the model, and make a decision based on the predicted information.

Abstract: This disclosure provides systems, methods and apparatuses for intelligent connectivity switching techniques. The techniques include, for example, determining that a wireless connection is encrypted, and in response to determining that the wireless connection is encrypted, employing one or more intelligent connectivity switching mechanisms to ensure a desirable level of user experience may be maintained and data stall conditions may be avoided or overcome. When a wireless station is in an area where two radio access technology (RAT) connections are present, the intelligent connectivity switching mechanisms can include responding to a user interface prompt, evaluating one or more signal-to-noise (SNR)-related metrics, or comparing an application, task or activity to a whitelist.

Abstract: An example computing device establishes a first network connection to a playback device that supports a first communication protocol for sending audio content for playback to the playback device, and detects user input associated with a modification to the playback. While the computing device and the playback device are connected to a common data network that supports a second communication protocol, the computing device transmits, via the common data network using the second communication protocol, a command to modify media playback based on the user input. While the computing device or playback device are not connected to the common data network that supports the second communication protocol, the computing device (i) establishes a second network connection to the playback device that supports a third communication protocol, and (ii) transmits, via the second network connection using the third communication protocol, a command to modify media playback based on the user input.

Abstract: Providing a voice call includes: receiving, from a user equipment (UE), a request to initiate a voice call traffic session; requesting setup of a voice call data pipe; based on at least a setup of the voice call data pipe not completing prior to a timer event, transmitting voice packets over a signaling data pipe; and based on at least the voice call data pipe setup completing, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe. Placing a voice call includes: requesting, by the UE, to initiate the voice call traffic session; based on at least a first trigger event, transmitting voice packets over the signaling data pipe; and based on at least a second trigger event, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during an active call on a first radio access technology (RAT), that a first condition for performing a handover from the first RAT to a second RAT is satisfied. The UE may determine that the second RAT would trigger a fallback to a third RAT after the handover from the first RAT to the second RAT and that a second condition for performing a handover from the third RAT to the first RAT is satisfied. The UE may refrain from performing the handover from the first RAT to the second RAT based at least in part on the determination that the second RAT would trigger the fallback and the determination that the second condition is satisfied. Numerous other aspects are provided.

Abstract: Embodiments of the present disclosure provide method and apparatus for handover management. A method performed by a first mobility management function in a first system comprises obtaining mobility management context for single radio voice call continuity (SRVCC). The method further comprises sending a forward relocation request to a second mobility management function in a second system during a handover from the first system to the second system. The forward relocation request comprises mobility management context for the SRVCC.
