Abstract: Various techniques and approaches described herein may be applied to control congestion at a session management (SM) function (SMF) based on at least one back-off timer maintained at a user equipment (UE). In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE may be configured to establish a protocol data unit (PDU) session with a SMF. The UE may be configured to determine whether a back-off timer associated with the PDU session is terminated. The UE may refrain from sending, to the SMF, data over a control plane associated with the PDU session when the back-off timer is unterminated. The UE may send, to the SMF, the data over the control plane associated with the PDU session when the back-off timer is terminated.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.

Abstract: A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Active (DSDA) mode or a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); determining a recommendation to change the DDS from the first SIM to a second SIM at a modem, informing a user of the recommendation to change the DDS; changing the DDS in response to, at least in part, the recommendation an input from the user; updating a first state variable to indicate a state of the DDS; and routing internet data to the second SIM.

Abstract: Certain aspects of the present disclosure provide techniques for communicating, by a user equipment (UE), over multiple slices. A method that may be performed by the UE includes receiving, by a modem, from an operating system (OS), a request for route identifier, the request for route identifier comprising a traffic descriptor corresponding to a first application from which the request for route identifier originated. The method further includes transmitting a route identifier to the OS, the route identifier generated by the modem based on a routing policy that provides mapping between the traffic descriptor and a network route. The method further includes receiving, by the modem, a start network request comprising the route identifier. The method further includes establishing, in response to the start network request, a network connection via the network route.

Abstract: In one aspect, a method includes determining, by a user equipment (UE), a pair identifier (ID); and transmitting, by the UE, a protocol data unit (PDU) session establishment message and the pair ID. In another aspect, a method include receiving, by a first network entity from a second network entity, a PDU session request message including a pair ID; and associating, by the network entity, a PDU session indicated by the PDU session request message with the pair ID. In yet another aspect, a method includes receiving, by a network entity from a UE, a PDU session establishment message and a pair ID; and transmitting, by the network entity, a PDU session request message responsive to the PDU session establishment message and including the pair ID.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a cellular connection with a base station associated with a cellular radio network. The UE may receive an access policy of the cellular radio network identifying an access preference rule for the UE to adopt for connections to a core network function of the cellular radio network, the access preference rule indicating for the UE to preferentially connect to the core network function via a non-cellular radio network. The UE may determine that a gateway between the non-cellular radio network and the core network function of the cellular radio network is not configured. The UE may determine that a gateway selection policy of the cellular radio network is not configured. The UE may establish a connection to a legacy core network function of a legacy cellular radio network via a legacy gateway.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may prevent rejected attachment requests when connecting to a trusted wireless local area network (WLAN) and from a wireless wide area network (WWAN). For example, an attachment packet data network (PDN) connection may be maintained with the WWAN while connected to the trusted WLAN. In some cases, the connection used to maintain the attachment may be an internet protocol (IP) multimedia subsystem (IMS) connection. Alternatively, the UE may determine that the WLAN connection is a trusted connection and deactivate the WWAN connection. Should the WLAN become unavailable the UE may reactivate the connection with the WWAN.

Abstract: A method of wireless communication by a UE (user equipment) includes transmitting a list to an IMS (IP multimedia subsystem) service center. The list includes multiple mobile station international subscriber directory numbers (MSISDNs). The method also includes receiving a paging message indicating different causes for the paging message. A method of wireless communications by a network determines whether a call initiator is in a list received from a UE (user equipment) in response to receiving a mobile terminated call for the UE. The list comprises multiple mobile station international subscriber directory numbers (MSISDNs). The network also transmits a message to the UE indicating whether the mobile terminated call is from one of the MSISDNs in the list.
