Abstract: The present disclosure relates to application server access methods and terminals. One example method includes in response to a terminal failing to connect to an application server by using an IPv6 address, setting an accessed domain name to a restricted domain name, and, when the accessed domain name is re-accessed later, connecting to the application server by directly using an IPv4 address.

Abstract: In an outbound transmission control method, a satellite network device segments an application layer packet into a plurality of Message Data Convergence Protocol (MDCP) protocol data units (PDUs) at an MDCP layer. The satellite network device sequentially delivers the MDCP PDUs to a satellite link control (SLC) layer as SLC service data units (SDUs) at the SLC layer, and segments the SLC SDU into N SLC PDUs at the SLC layer. SLC PDUs of one or more users are obtained at a physical layer (PHY) from the SLC layer. The SLC PDUs of the one or more users are spliced together at the PHY to form outbound data of a physical slot with a fixed length. The satellite network device in turn sends the outbound data to one or more terminals.

Abstract: The present invention provides an electronic device, a method, and a chip for sending data. The method includes: When a terminal device is in a dual-connectivity state, the terminal device determines a foreground application that is currently being run. When the application that is being run in a foreground is a present application, the terminal device further determines whether that is being of to-be-sent data is a data packet of a present type or a hardware resource occupation status of the terminal device; and sends the data packet of the present type, respectively sends the two data packets through two links, to implement transmission accuracy of sensitive data.
