Abstract: The present invention provides a communication security processing method and an apparatus. The communication security processing method includes: determining, by a base station, that user equipment UE needs to access an access point AP; acquiring, by the base station, a security parameter that is required for the UE to interact with the AP; after an air interface is securely activated, sending, by the base station, the security parameter to the UE, so that the UE performs, by using the security parameter, security processing on data exchanged between the UE and the AP. According to the communication security processing method and the apparatus that are provided in the present invention, a security air interface between UE and a base station is used to transfer a security-related parameter, which improves data communication security, and enhances network control performed by an operator.

Abstract: Embodiments of the present disclosure disclose a data retransmission communication method and a terminal for implementing inter-base station carrier aggregation, where the method includes: receiving, by a first Radio Link Control (RLC) entity of a terminal, a packet data unit PDU; and when the first RLC entity determines that the PDU reaches a maximum quantity of retransmissions, instructing, by the first RLC entity, a second RLC entity of the terminal to transmit the PDU, where the first RLC entity is corresponding to a first base station, and the second RLC entity is corresponding to a second base station. By using the method and the terminal in the embodiments, frequency of RRC connection re-establishment is reduced, and a data packet loss caused by frequent re-establishment is further avoided, thereby improving user experience.
