Method and system for transmitting multi-carrier enhanced dedicated channel data

A method for sending multi-carrier enhanced dedicated channel data, comprising:

• a drift radio network controller receiving an enhanced dedicated channel uplink data frame sent by a node B which only has an enhanced dedicated channel cell of a single carrier frequency layer in multi-carrier;
• and
• if all the nodes B governed by the drift radio network controller are all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier and are in an identical carrier frequency layer, the drift radio network controller not processing the received enhanced dedicated channel uplink data frame and sending the received enhanced dedicated channel uplink data frame to the serving radio network controller;
• if all the nodes B governed by the drift radio network controller are nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier but do not belong to an identical carrier frequency layer, or if all the nodes B governed by the drift radio network controller are not all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, the drift radio network controller setting “uplink multiplexing information” which is “null” in the received enhanced dedicated channel uplink data frame as carrier identifier information of the carrier for receiving data carried in the enhanced dedicated channel uplink data frame and sending that enhanced dedicated channel uplink data frame to the serving radio network controller.

A system for transmitting multi-carrier enhanced dedicated channel data, comprising:

• a first node B and a first serving radio network controller, wherein:
• the first node B is configured to set “uplink multiplexing information” in an enhanced dedicated channel uplink date frame to be “null” and send the enhanced dedicated channel uplink data frame to the first serving radio network controller when the first node B only has the enhanced dedicated channel cell of a single carrier frequency layer in multi-carrier;
• the first serving radio network controller is configured:
• to receive an enhanced dedicated channel uplink data frame sent by a first node B of a sender which only has an enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, and to distinguish which carrier in the multi-carrier is a carrier for receiving data carried in the enhanced dedicated channel uplink data frame based on carrier identifier information corresponding to a carrier frequency of an enhanced dedicated channel cell recorded when the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier is established or added in advance;
• or, the system comprises:
• a second node B, a drift radio network controller and a second serving radio network controller, wherein:
• the second node B is configured:
• to set “uplink multiplexing information” in the enhanced dedicated channel data frame to be “null” when the second node B only has the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier;
• and to send the enhanced dedicated channel uplink data frame to the drift radio network controller;
• the drift radio network controller is configured to receive the enhanced dedicated channel uplink data frame sent by the second node B which only has an enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier;
• and
• if all the nodes B governed by the drift radio network controller are nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier and are in an identical carrier frequency layer, the drift radio network controller not processing the received enhanced dedicated channel uplink data frame and sending the received enhanced dedicated channel uplink data frame to the second serving radio network controller;
• if all the nodes B governed by the drift radio network controller are nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier but do not belong to an identical carrier frequency layer, or if all the nodes B governed by the drift radio network controller are not all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, the drift radio network controller setting “uplink multiplexing information” which is “null” in the received enhanced dedicated channel uplink data frame as carrier identifier information of a carrier for receiving data carried in the enhanced dedicated channel uplink data frame and sending that enhanced dedicated channel uplink data frame to the second radio network controller;
• the second serving radio network controller is configured:
• to receive the enhanced dedicated channel uplink data frame sent by the drift radio network controller of a relay party which only has an enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, and to distinguish which carrier in the multi-carrier is a carrier for receiving data carried in the enhanced dedicated channel uplink data frame based on the carrier identifier information corresponding to the carrier frequency of the enhanced dedicated channel cell recorded when the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier is established or added in advance.

A drift radio network controller, which is configured:

• to receive an enhanced dedicated channel uplink data frame sent by a node B which only has an enhanced dedicated channel cell of a single carrier frequency layer in multi-carrier;
• and
• to not process the received enhanced dedicated channel uplink data frame and send the received enhanced dedicated channel uplink data frame to a serving radio network controller if all the nodes B governed by the drift radio network controller are all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier and are in an identical carrier frequency layer;
• to set “uplink multiplexing information” which is “null” in the received enhanced dedicated channel uplink data frame as carrier identifier information of a carrier for receiving data carried in the enhanced dedicated channel uplink data frame and send that enhanced dedicated channel uplink data frame to the serving radio network controller, if all the nodes B governed by the drift radio network controller are all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier but do not belong to an identical carrier frequency layer or if all the nodes B governed by the drift radio network controller are not all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier.
