Abstract: A solution for security negotiation during handover of a user equipment (UE) between different radio access technologies is provided. In the solution, the UE receives non-access stratum (NAS) security information and access stratum (AS) security information which are selected by the target system and then performs security negotiation with the target system according to the received NAS security information and AS security information. As such, the UE may obtain the key parameter information of the NAS and AS selected by a Long Term Evolution (LTE) system and perform security negotiation with the LTE system when the UE hands over from a different system, such as a Universal Terrestrial Radio Access Network (UTRAN), to the LTE system.

Abstract: Embodiments of the present invention are related to a resource scheduling method and apparatus, so as to reduce a sending latency of resource scheduling to meet a sending latency requirement of a future service. The method includes: when determining that a service that needs to be carried meets a trigger condition of sending a resource scheduling request, sending, by a terminal, the resource scheduling request to a base station, where the resource scheduling request is used to request the base station to allocate an uplink resource to the terminal, and the resource scheduling request includes at least one of a priority indication of the service, a scheduling-free sending indication, a scheduling-free sending failure indication, a semi-persistent resource request, and a data buffer size indication; and allocating, by the base station, the uplink resource to the terminal based on the resource scheduling request. In such resource scheduling manner, a sending latency of a service can be reduced.

Abstract: Embodiments of the present invention disclose a security processing method and system in a network handover process. The method includes: generating, by a network switching node, a target key after receiving a handover request; sending, by the network switching node, security information including the target key to a target network node, and receiving a handover response message sent by the target network node; and sending, by the network switching node, a handover command to a mobile terminal, so that the mobile terminal accesses a target network. By adopting the present invention, security processing in handover of a mobile terminal from a 3G network to an HSPA network or an LTE network may be completed in a case that the network switching node currently used in the network is not changed.

The method for synchronizing an uplink ciphering parameter in unacknowledged mode includes: sending an indication message to a terminal when detecting that an unrecoverable error occurs in an uplink packet or that the uplink packet is invalid, where the indication message is used to instruct the terminal to initialize an uplink ciphering parameter; receiving a response message sent by the terminal; and initializing the uplink ciphering parameter according to an initial value of the ciphering parameter. The embodiments of the present invention solve a service defect, namely, a break of the communication link caused by synchronization of an uplink ciphering parameter between the terminal and the radio network controller in unacknowledged mode, and shorten the time of synchronizing the uplink ciphering parameter without interrupting the service.
