Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a modem of a user equipment (UE) may receive one or more parameters that configure the modem to perform a periodic communication to maintain a first connection of the UE; and perform the periodic communication based at least in part on the one or more parameters, wherein the periodic communication is performed on a second connection different than the first connection. In some aspects, an application processor of a UE may establish a connection with a server for a plurality of applications, the server to be configured to communicate with respective application servers for the plurality of applications; configure a modem of the UE to perform a periodic communication to maintain the connection; and provide a push notification, received via the connection and associated with an application of the plurality of applications, to the application.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for enabling access control in a connected mode, idle mode, and an inactive state. An exemplary method generally includes receiving access control information associated with one or more services used by the UE for communicating with the wireless communications network, receiving a request to transmit traffic using the one or more services, checking a type of the traffic against the access control information, and scheduling the traffic for transmission if the type of the traffic satisfies one or more criteria in the access control information based on the checking.

Abstract: Methods and devices for wireless communication are disclosed. For example, one method includes detecting a loss of connectivity between a user equipment and a network, the user equipment having at least a first and second layer of a communication protocol. The method further includes sending messages from the first layer to the second layer, at least one message of the messages being delayed at the second layer based on the loss of connectivity. The method also includes identifying, at the first layer, at least one trigger condition, determining, at the first layer, to abort the sending of a first delayed message to the network based on the identified at least one trigger condition, communicating, by the first layer, to the second layer the determination to abort the first delayed message; and aborting the sending of the first delayed message at the second layer.

Abstract: Aspects of the disclosure are directed to congestion control in a user equipment in connected mode including upon receipt of a trigger, using a register to determine if a data packet transmission has been initiated by an application associated with the UE, wherein the UE is in a connected mode; retrieving an Application-specific Congestion control for Data Communication (ACDC) category mapped to the application associated with the UE, wherein a mapping between the ACDC category and the application is performed a priori to a transition to the connected mode; retrieving at least one access control parameter based on the ACDC category; and determining if the application is allowed to perform the data packet transmission based on the at least one access control parameter.

Abstract: Systems, methods and apparatus for non-optimized handoffs for wireless communication are provided. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network.

Abstract: Commonly, when a mobile device tethers to a computer, one Internet Protocol address is provided. When an embedded application runs continuously, such as with a Internet Protocol Multimedia Subsystem application, tethered applications can be prohibited from operating. If the continuous application is not active, then the continuous application can be disconnected and thus the tethered application can function.

Abstract: A broadband service is provided by allocating air interface resources in a wireless network that conforms to the 1xEV-DO standard. The air interface resources are characterized by various quality of service (QoS) parameters, such as bandwidth, packet priority and error rate. Packetized information is transmitted in data flows between a base station and cell phones. A particular QoS level is reserved for each of the data flows that support the broadband service. An operating system on a cell phone monitors one data flow as well as another data flow in the opposite direction. When the base station runs out of an air interface resource, the base station suspends the QoS reservation of a data flow. The operating system determines that the QoS reservation in one direction has been suspended and sends an unsolicited message to the base station releasing the QoS reservation in the opposite direction, thereby conserving network resources.

Abstract: More seamless handoff between access networks is achieved by saving session information for each access network upon being handed off from the access network and invoking the saved session information upon being handed back to the access network. An access terminal establishes a first session with a first access network, which may entail performing QoS negotiation with the first access network and setting up packet filters at a packet data gateway. The access terminal exchanges data with the first access network in accordance with the configuration of the first session. The access terminal saves the first session configuration after being handed off to a second access network, establishes a second session with the second access network, and exchanges data with the second access network in accordance with the configuration of the second session. The access terminal uses the saved first session configuration upon being handed back to the first access network.
