Abstract: A data transmission method, a data receiving device, and a data sending device are disclosed. An RLC protocol entity unit of a data receive end receives a TCP acknowledgement from a TCP protocol entity unit of the data receive end; and the RLC protocol entity unit sends indication information to an RLC protocol entity unit of a data transmit end, where the indication information is used to indicate whether the RLC protocol entity unit needs to generate a TCP acknowledgement. The RLC protocol entity unit receives the indication information from the RLC protocol entity unit, and sends the TCP acknowledgement to a TCP protocol entity unit of the data transmit end based on the indication information, to ensure that the TCP protocol entity unit ultimately receives only one TCP ACK for one TCP data packet.

Abstract: The present invention relates to the communications field, and discloses user equipment and a network access method, so as to resolve a problem of service transmission interruption caused by a relatively long time for UE to access a network again after the UE fails to access a network or detects an RLF or an HOF in a current cell. In a specific solution, an obtaining unit obtains access information for accessing a network in a first cell, and the first cell is a cell included in a list pre-stored on the UE. A storage unit stores the access information obtained by the obtaining unit. A determining unit determines that accessing a network in the first cell is required. An access unit accesses a network in the first cell according to the access information stored in the storage unit.

Abstract: The present invention relates to wireless communications technologies, and in particular, to a terminal, a network device, and a data transmission method in a random access process, so as to resolve a current problem that a transmission delay is relatively long when a terminal transmits a relatively large data packet in a random access process. In the terminal a processing module, is configured to determine that the terminal transmits data of multiple TTIs to a base station in a current random access process; and a transceiver module is configured to send first indication information to the base station, where the first indication information is used to indicate that the terminal transmits the data of the multiple TTIs in the current random access process. In this way, the terminal can transmit data of multiple TTIs in one random access process.
