Apparatuses, systems, and methods for application awareness interworking between cellular systems. A wireless device may be configured to initiate an application during an ongoing procedure serviced by a first operating according to a first radio access technology (RAT), receive, from a first cellular system, an indication to switch to a second cellular system operating according to a second RAT, and delay the switch to the second cellular system until completion of the ongoing procedure. A network function may be configured to detect initiation of an application during an ongoing procedure serviced by a cellular system operating according to a first RAT, the application having associated application preferences, determine that the associated application preferences indicate a switch to a second cellular system operating according to a second RAT, and delay the switch to the second cellular system until completion of the ongoing procedure.

The present disclosure provides a method for improving call performance in a wireless network. The method includes sending an invite request to a server to initiate a Voice over New Radio (VoNR) service, where the UE is connected with a first network entity, and where the invite request comprises a media feature tag. The method includes initiating an Evolved Packet System fallback (EPS FB) service timer based on the media feature tag and a quality of service (QoS) timer and establishing a call over a second network entity using a dedicated bearer when the EPS FB command is received from the server. The call is established over the second network entity using the dedicated bearer by sending a service request to the server and/or sending an update request to the server when the EPS FB timer is expired and the EPS FB command is not received from the server.

Wireless communications systems and methods related to downlink performance of a UE in a wireless communication network are provided. For example, method of wireless communication performed by a user equipment (UE), the method comprising determining a level of interference to a reference signal received from a serving base station operating a first radio access technology (RAT) and switching, based on the determined level of interference, a radio access technology mode preference of the UE to a second RAT, the second RAT being different from the first RAT. Other features are also claimed and described.

Aspects of the subject disclosure may include, for example, detecting initiation of a service associated with a UE, where the service comprises an OTT voice/video call, facilitating, for the service, activation of an end-to-end network slice between a core network and the UE, detecting a RAT switch determination for the UE, where the RAT switch determination relates to communicative coupling of the UE with a second network node, and where the second network node is associated with a second RAT different from the first RAT, responsive to the detecting the RAT switch determination, determining whether the service is ongoing over the end-to-end network slice, and, based on a determination that the service is ongoing over the end-to-end network slice, preventing the UE from communicatively coupling with the second network node until the service is determined to be completed or until the end-to-end network slice is released. Other embodiments are disclosed.

An apparatus includes a includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives signaling that indicates edge application service relocation for transferring a user equipment (UE) session for a UE to a target edge data network. The processor identifies an edge application service in the source edge data network processing media content corresponding to the UE session; generates a resource template for the edge application service including requirements for running the edge application service; transmits a request for the edge application service relocation to the target edge data network, the request including the resource template; and enables the edge application service relocation for the user equipment from the edge application service at the source edge data network to an edge application service at the target edge data network.

A method for connecting user equipment (UE) to data network name (DNN) in public network integrated non-public network (NPN) is provided. The method includes identifying prioritized DNN and corresponding network slice, from list of prioritized DNNs and network slices, when UE (moves from first location to second location, where session management (SM) retry timer is enabled, disabling SM retry timer based on identification, evaluating user route selection policy (URSP) rule for connecting UE to prioritized DNN and corresponding network slice. Further, the disclosure relates to method receiving rejection cause when UE sends request to connect to higher priority DNN and via corresponding network slice, where SM retry timer is enabled, detecting inactivity of packet transmission for pre-determined time period, and evaluating URSP rule, where UE is connected to higher priority DNN, and corresponding network slice.
