    • The present invention relates to a relocation method, system and network element for changing a serving radio resource control entity. After an initial operating state in which a user equipment (30) has radio links with a serving network element (20) and a drift network element (21) supporting said serving network element (20) with a wireless connection, the serving network element (20) transmits a relocation-specific information to a target network element (22). Based on the relocation-specific information, the target network element (22) establishes a link to the drift network element (21), such that the drift network element (21) can receive user traffic from both the serving network element (20) and the target network element (20). Then, the radio resource control is relocated to the target network element (20). The relocation-specific information may comprise an identifier or a list of identifiers of drift network elements. Thus, existing soft handover techniques can be enhanced by allowing a user plane connection to be maintained with drift net-work elements. Thereby, any amount of drift network elements can be kept, with improved radio performance as a consequence.
    • 本发明涉及一种用于改变服务无线电资源控制实体的重定位方法,系统和网元。 在用户设备(30)具有与服务网元(20)的无线链路的初始操作状态和利用无线连接支持所述服务网元(20)的漂移网元(21)之后,服务网元( 20)向目标网络元件(22)发送重定位特定信息。 基于重定位特定信息,目标网元(22)建立到漂移网元(21)的链路,使得漂移网元(21)可以从服务网元(20)和 目标网元(20)。 然后,无线资源控制被重定位到目标网元(20)。 重定位特定信息可以包括漂移网络元件的标识符或标识符列表。 因此,现有的软切换技术可以通过允许用漂移网络元件维持用户平面连接来增强。 因此,可以保持任何数量的漂移网络元件,结果改善了无线电性能。
