Abstract: A packet switched (PS) service identification method and a terminal, where a weight of at least one socket corresponding to a PS service is determined, a key socket is determined from the at least one socket according to the weight of the at least one socket, and an identifier of the key socket is sent to a network side such that the network side formulates a policy and charging control (PCC) rule according to the 5-tuple. In this PS service identification process, because the terminal does not encrypt the PS service, the terminal can accurately identify the PS service.

Abstract: A network performance improvement method and an apparatus for user equipment. In the network performance improvement method, user equipment establishes a first PDN connection and transmits data of a first application program through the first PDN connection. Then, the user equipment starts a second application program and determines whether a current network status satisfies a quality of service requirement of the second application program. When determining that the current network status does not satisfy the quality of service requirement of the second application program, the user equipment starts to establish a second PDN connection, and transmits, after the second PDN connection is successfully established, at least a part of application data of the second application program through the second PDN connection.

Abstract: Embodiments of the present disclosure resolve problem of power consumption caused because an AP is frequently woken up. This solution includes: receiving, by a modem, pre-processing information, which is sent by an application processor AP, of an application, where the pre-processing information includes at least a period range value and first data that are of the application, the period range value is used to represent frequency at which the application needs the AP to send and receive the first data, and the first data is data that the application needs the AP to send to a server; invoking, by the modem, preset functions according to the period range value and a time at which the modem receives the pre-processing information, to determine a sending time of the first data; and sending, by the modem, the first data to the server according to the sending time.

Abstract: A packet transmission method and related apparatus are disclosed. A transmit end retransmits a first packet to a receive end and decreases a congestion window and a slow start threshold upon determining that the first packet has been lost. The receive end sends an ACK in response to the retransmitted first packet to the transmit end on receipt of the retransmitted first packet for the first time, where the ACK contains a proactively constructed DSACK option for informing the transmit end that the first packet has been received repeatedly. The transmit end therefore compensates the congestion window and/or the slow start threshold.

Abstract: This application provides a packet sending method, an apparatus and a chip. The method is applied to a terminal, the terminal includes a baseband processor, an application processor, and a communications interface. The baseband processor reports information about a first packet to the application processor, where the first packet is a to-be-sent packet discarded by the baseband processor. The application processor transmits a second packet to the baseband processor according to the information about the first packet, where the second packet is the same as the first packet. The baseband processor sends the second packet to a network device by using the communications interface.
