Abstract: Embodiments of the present invention provide a cell handover method and a device. so that the target eNB uses a current serving small node as a user plane serving node after UE is handed over and uses the target eNB as a control plane serving node after the UE is handed over; receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. This avoids a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great because the current serving small node forwards a large amount of data to the target eNB.

Abstract: Embodiments of the present invention provide a data transmission method, an apparatus, and a communications system. The method includes sending, by a macro base station, a configuration request message to an access node, where the configuration request message includes a bearer configuration parameter that carries a radio bearer (RB) identifier; receiving, by the macro base station, a configuration success message from the access node, where the configuration success message carries at least physical layer parameter configuration information that is configured by the access node for a user equipment; and sending, by the macro base station, a reconfiguration message to the user equipment. The reconfiguration message includes at least the RB identifier and/or a logical channel identifier that is reconfigured to transmit on the access node and the physical layer parameter configuration information of the access node.

Abstract: Embodiments of the present invention disclose a method and an apparatus for implementing a group call service. A user equipment of the trunking group call service receives group configuration information and a downlink assignment message and/or an uplink grant message from an evolved cell. The user equipment saves the group configuration information and the downlink assignment message and/or the uplink grant message. If the user equipment is in a group receive state at different points of time, trunking group call service data is saved by sharing a downlink resource, indicated by the downlink assignment message, with another user equipment in the group in a semi-persistent scheduling manner according to the group configuration information.
