Abstract
Disclosed are a method for modification in dual-connection mode and a device. The method for modification in dual-connection mode provided includes: an MN determines an SN to which at least one flow is to be transferred, the MN sending to the SN a transfer instruction carrying the indication information of the PDU session to which the at least one flow belongs, the transfer instruction is used for the SN to determine whether to receive the flow transferred by the MN, the indication information of the PDU session is used for indicating that the at least one flow includes part or all of the flow under a PDU session.
Claims18
A method for modification in a dual-connection mode, comprising:
- determining, by a master node (MN), a secondary node (SN) to which at least one flow is to be transferred;
- and
- sending, by the MN, to the SN a transfer instruction carrying indication information of a protocol data unit (PDU) session to which the at least one flow belongs;
- wherein the transfer instruction is used for the SN to determine whether to receive the at least one flow transferred by the MN;
- wherein the indication information of the PDU session comprises information for indicating that the at least one flow comprises part or all of flows under the PDU session;
- wherein before sending, by the MN, to the SN the transfer instruction, the method further comprises:
- placing, by the MN, the indication information of the PDU session in a list of PDU sessions to be setup in the transfer instruction;
- wherein, the indication information of the PDU session is a split indicator newly added into PDU Session resource set up info-SN terminated IE in the list of PDU sessions to be setup, when the split indicator is set as non-SPLIT, the MN sends all of the flows under the PDU session to the SN, and when the split indicator is set as SPLIT, the MN sends part of the flows under the PDU session to the SN.
A method for modification in a dual-connection mode, comprising:
- receiving, by a secondary node (SN), a transfer instruction carrying indication information of a protocol data unit (PDU) session to which at least one flow belongs sent by a master node (MN);
- and
- determining, by the SN, whether to receive the at least one flow transferred by the MN according to the transfer instruction;
- wherein the indication information of the PDU session comprises information for indicating that the at least one flow comprises part or all of flows under the PDU session;
- wherein the indication information of the PDU session is placed in a list of PDU sessions to be setup, and the indication information of the PDU session is a split indicator newly added into PDU Session resource set up info-SN terminated IE in the list of PDU sessions to be setup, when the split indicator is set as non-SPLIT, the MN sends all of the flows under the PDU session to the SN, and when the split indicator is set as SPLIT, the MN sends part of the flows under the PDU session to the SN.
A device for modification in a dual-connection mode, comprising:
- a processor, a memory and a transceiver;
- wherein
- the processor is configured to read a program in the memory and execute a following process:
- determining an SN to which at least one flow is to be transferred;
- and sending to the SN a transfer instruction carrying indication information of a PDU session to which the at least one flow belongs;
- wherein the transfer instruction is used for the SN to determine whether to receive the at least one flow transferred by an MN;
- wherein the indication information of the PDU session comprises information for indicating that the at least one flow comprises part or all of flows under the PDU session;
- wherein the processor is further configured to:
- place the indication information of the PDU session in a list of PDU sessions to be setup in the transfer instruction;
- wherein, the indication information of the PDU session is a split indicator newly added into PDU Session resource set up info-SN terminated IE in the list of PDU sessions to be setup, when the split indicator is set as non-SPLIT, the MN sends all of the flows under the PDU session to the SN, and when the split indicator is set as SPLIT, the MN sends part of the flows under the PDU session to the SN.
