<p>The present invention discloses a method for joint transmission, wherein, an anchor network element sends a joint transmission request to a non-anchor network element; after receiving a joint transmission response sent from the non-anchor network element, the anchor network element allocates radio resources for a user equipment in the system which the anchor network element itself belongs to, wherein, the joint transmission response includes the radio resources allocated by the non-anchor network element; the anchor network element sends bearer establishment or reconfiguration signaling to the user equipment through RRC signaling, wherein, the bearer establishment or reconfiguration signaling carries the radio resources for the user equipment, according to which the user equipment performs the joint transmission, allocated respectively by itself and the non-anchor network element. The present invention also discloses a system and an anchor network element for joint transmission. With the solutions of this invention, the cross-system joint transmission of the user equipment data is implemented, and the problem of RRC connection maintenance, wherein the user equipment simultaneously accesses two systems, is solved.</p> |
