Abstract: A method and apparatus for timing advance (TA) synchronization for uplink (UL) data transmissions are provided. A base station transmits a TA instruction to a UE. The TA instruction indicates one of at least two TA options. The first TA option indicates direct initial grant-free (GF) uplink (UL) data transmissions. The second TA option indicates indirect initial GF UL data transmissions with the UE initiating TA reference signaling for updating a TA parameter of the UE. The UE performs an initial GF UL data transmission to the base station based on the TA instruction.

Abstract: The embodiment of the present disclosure provided a method, device, and system for processing a message. The method for processing a message comprises obtaining a traffic type of a service data packet, sending the message or a data packet that carries the traffic type to a radio network controller, where the radio network controller obtains the traffic type and performs scheduling processing on the service data packet according to a quality of service requirement corresponding to the traffic type. The present disclosure can realize performing resource allocation and scheduling processing on the applications corresponding to the service data packet based on the traffic type. Compared to resource allocation and scheduling processing based on the traffic type in the prior art, the granularity of classification of the present disclosure is more refined, and can realize more refined resource allocation and scheduling processing, and can effectively improve the efficiency of scheduling processing.

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.

Abstract: Embodiments of the present invention include a bearer switching method, a home NodeB gateway, and a home NodeB. The method includes: receiving a first relocation request message sent by a source home NodeB HNB, where the first relocation request message is used to request switching of a local IP access LIPA bearer; and determining, according to the first relocation request message, whether a target HNB supports LIPA mobility, so as to perform a corresponding switching operation. According to the bearer switching method, switching of an LIPA bearer is effectively managed, thereby saving a resource and signaling, and avoiding resource waste and an invalid signaling overhead caused when an HNB that does not support the LIPA mobility prepares the resource for the LIPA bearer.
