    • Methods and devices are disclosed for forwarding data packets during handover in a packet-switched wireless communications system, such as a 3GPP Long-Term Evolution/System Architecture Evolution system. In an exemplary method, a source base station node (410, 900) determines (520) that handover of at least one radio bearer for a served user terminal (160) to a target base station node (430, 900) is imminent. The source base station node (410, 900) classifies (530) a plurality of data packets into two or more data flow classifications according to a transmission status for each data packet, a service requirement for each data packet, or both and selectively forwards (540) one or more of the data packets to the target base station node (430, 900) based on the data flow classification for each data packet. In some embodiments, the source base station node (410, 900) classifies (530) the data packets by inspecting (610) an Internet Protocol header for each packet to determine a corresponding service requirement. In some embodiments, the source base station node (410, 900) classifies (530) data packets by evaluating (650) a radio link control status to determine a transmission status for each data packet. In either case the source base station node (410, 900) selectively forwards (540) data packets corresponding to one or more of the classifications. For example, data packets associated with a reliable delivery service requirement may be forwarded while data packets associated with a maximum delay service requirement are not.
    • 公开了用于在分组交换无线通信系统(诸如3GPP长期演进/系统体系结构演进系统)中的切换期间转发数据分组的方法和设备。 在示例性方法中,源基站节点(410,900)确定(520)用于所服务的用户终端(160)的至少一个无线电承载到目标基站节点(430,900)的切换即将发生。 源基站节点(410,900)根据每个数据分组的传输状态,每个数据分组的服务要求或两者将多个数据分组分类(530)为两个或更多个数据流分类,并且选择性地将 540)基于每个数据分组的数据流分类将一个或多个数据分组发送到目标基站节点(430,900)。 在一些实施例中,源基站节点(410,900)通过检查(610)每个分组的互联网协议报头来确定相应的服务要求来对数据分组进行分类(530)。 在一些实施例中,源基站节点(410,900)通过评估(650)无线电链路控制状态以确定每个数据分组的传输状态来对数据分组进行分类(530)。 在任一情况下,源基站节点(410,900)选择性地转发(540)与一个或多个分类对应的数据分组。 例如,与可靠递送服务要求相关联的数据包可以被转发,而与最大延迟服务要求相关联的数据包则不被转发。
