摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may coordinate and improve data flows between wireless communication networks based on messaging between a modem processor and an application processor. In a first example, the modem processor may control the splitting of traffic between a first wireless communication network (e.g., a cellular network) and a second wireless communication network (e.g., a Wi-Fi network). The modem processor may establish a multiple access session (e.g., a multiple access protocol data unit session) that includes a session for each wireless communication network, and route traffic (e.g., communications with a network entity) based on access traffic steering, switching, and splitting (ATSSS) rules. In a second example, the application processor may control the traffic splitting. The application processor may obtain the ATSSS rules from the modem processor, and route traffic accordingly.

摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for limiting handoffs in cellular networks. In some aspects, a user equipment (UE) may determine a quantity of handoffs that are performed between two or more radio access technologies (RATs) during a time period. The UE may determine whether the quantity of handoffs exceeds a handoff threshold within the time period. The UE may reduce a rate of handoffs when the UE determines that the quantity of handoffs exceeds the handoff threshold within the time period. The UE also may select one of the RATs to camp on and maintain the wireless connection when the UE determines that the quantity of handoffs exceeds the handoff threshold. The UE may determine which RAT to camp on based on handoff count information, handoff total connection time information, or contextual awareness information.

摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a user equipment (UE) to select a data connection based on which applications are active in a foreground process of an application processor. The UE may activate a dedicated data subscription (DDS) based on a list of active applications. In some aspects, the UE may programmatically initiate a DDS switch based on which applications are active. The UE may determine which data connection to activate as the DDS based on the application configuration information and which applications are active. Application configuration information may indicate preferences regarding different data connections to use for each application. The application configuration information may indicate a preferred radio access technology (RAT), a preferred communication network, a preferred subscription, or any combination thereof.

摘要： A user equipment (UE) modem stores a route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice. The modem establishes a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID. The modem establishes a second PDU session with the first DNN and the second slice in response to receiving a second indication to start a second network interface associated with the second DNN ID.

摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for tracking network traffic for local area network (LAN) subnets in a wireless wide area network (WWAN). In some implementations, a UE of the WWAN may assign a unique public IP address to each router of the LAN. The UE may transmit network traffic received from the LAN to the WWAN. The network traffic originating from any router of the LAN may be associated with the unique public IP address that was assigned to that router. The WWAN may use the unique public IP addresses to generate network traffic information that may indicate amounts of network traffic flowing from each router of the LAN. The WWAN, for example, may use the network traffic information to determine billing information for any router in the LAN.

摘要： Certain aspects of the present disclosure provide techniques for a domain name system (DNS) override for edge computing. Embodiments include receiving signaling indicating an address of a DNS server. Embodiments include receiving signaling indicating an address of an edge DNS server. Embodiments include intercepting a DNS request from an application. Embodiments include changing a destination address of the DNS request to the address of the edge DNS server. Embodiments include intercepting a DNS response from the edge DNS server that is sent in response to the DNS request. Embodiments include upon determining that the DNS response does not comprise a failure notification, changing a source address of the DNS response to the address of the DNS server.

摘要： An apparatus for wireless communication includes a memory and a processor coupled to the memory. The processor is configured to send a data session establishment request to establish a data session with a network device using a wireless communication network. The data session establishment request has a first field to indicate a requested network slice for the data session. The processor is further to receive an indication of a granted network slice for the data session and to receive an indication of a back-off timer value from the network device. The processor is further configured, after expiration of a back-off timer based on the back-off timer value, to send a first message associated with the granted network slice and to send a second message having a second field corresponding to the first field of the data session establishment request.

摘要： Methods, systems, and devices for wireless communications are described that provide for establishment and maintenance of edge data network services. A user equipment (UE) may register one or more application clients for edge services at an edge application server. In order to maintain edge application servers that are continuing to be used by the UE, an edge enabler server at the edge data network, an edge enabler client at the UE, or both, may initiate a timer that is used to confirm the edge application server is continuing to be used. Such techniques may help prevent resources from being consumed after the edge services are no longer needed, such as after the UE no longer needs the edge services or the UE has moved outside of an area associated with the edge services.
