Abstract: 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.

Abstract: 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.

Abstract: 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.

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: Methods, systems, and devices are described for wireless communication. A modem processor of a user equipment (UE) may receive a switch indication directing the modem to utilize a designated SIM and may access identification (ID) information from the SIM, including ID information for a network operator. The modem processor may then retrieve a stored access point name (APN) associated with the network operator and establish a connection to the data network identified by the stored APN. In some cases, the APN may be stored in the modem processor after a successful connection to the data network using the designated SIM. In some cases, the UE may also identify a network priority rule associated with the network operator of the SIM and establish the connection to the data network based on the priority rule.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 用户设备（UE）的调制解调器处理器可以接收指示调制解调器利用指定的SIM的交换机指示，并且可以从SIM接入标识（ID）信息，包括网络运营商的ID信息。 调制解调器处理器然后可以检索与网络运营商相关联的存储的接入点名称（APN），并建立与由所存储的APN标识的数据网络的连接。 在某些情况下，APN可以在使用指定的SIM成功连接到数据网络之后存储在调制解调器处理器中。 在一些情况下，UE还可以识别与SIM的网络运营商相关联的网络优先级规则，并基于优先级规则建立与数据网络的连接。
