Problems solved by technology

[0004] The source base station actually doesn’t care about the content of the RRCReconfiguration information element carried by the destination to the UE, so it is completely unnecessary to decode and re-encode it, which will increase the system overhead and have a significant impact on system efficiency in the multi-user handover scenario

Embodiment 1

[0025] Such as figure 1 As shown, this embodiment proposes a method for improving the execution efficiency of XN handover in the NR system, the method is:

[0026] By redesigning the Target NG-RANnode To Source NG-RAN node Transparent Container information element in the HANDOVER REQUEST ACKNOWLEDGE signaling in the XN interface, the execution efficiency of XN handover in the NR system is improved.

[0027] Further, the method of redesigning the Target NG-RAN node To Source NG-RAN node Transparent Container information element in the HANDOVER REQUEST ACKNOWLEDGE signaling in the XN interface is:

[0028] (1) Construct the RRCReconfiguration information element into a DL-DCCH-Message message;

[0029] (2) Encode the constructed DL-DCCH-Message message, and put the coded stream into the Target NG-RAN node To Source NG-RAN node Transparent Container cell to obtain the redesigned Target NG-RAN node To Source NG-RAN node Transparent Container cells.

[0030]Therefore, the redesi...

Embodiment 2

[0032] Based on the method for improving the execution efficiency of NR system XN handover described in Embodiment 1, as figure 1 As shown, this embodiment proposes an NR system XN handover method, including the following steps:

[0033] S1, the source base station initiates a handover request HANDOVER REQUEST to the destination base station through the XN port;

[0034] S2. After receiving the handover request HANDOVER REQUEST, the target base station prepares for the handover, and then sends the HANDOVER REQUEST ACKNOWLEDGE signaling to the source base station. The HANDOVER REQUEST ACKNOWLEDGE signaling includes the redesigned Target NG-RAN node To Source NG-RAN node Transparent Container information element; the redesigned Target NG-RAN node To Source NG-RAN node TransparentContainer information element carries the encoded code stream of the DL-DCCH-Message message containing the RRCReconfiguration information element;

[0035] S3. After receiving the HANDOVER REQUEST ACKN...

Embodiment 3

[0037] This embodiment proposes an NR system, the NR system includes a source base station, a destination base station, and a UE, and XN handover is performed according to the following NR system XN handover method:

[0038] S1, the source base station initiates a handover request HANDOVER REQUEST to the destination base station through the XN port;

[0039] S2. After receiving the handover request HANDOVER REQUEST, the target base station prepares for the handover, and then sends the HANDOVER REQUEST ACKNOWLEDGE signaling to the source base station. The HANDOVER REQUEST ACKNOWLEDGE signaling includes the redesigned Target NG-RAN node To Source NG-RAN node Transparent Container information element; the redesigned Target NG-RAN node To Source NG-RAN node TransparentContainer information element carries the encoded code stream of the DL-DCCH-Message message containing the RRCReconfiguration information element;

[0040] S3. After receiving the HANDOVER REQUEST ACKNOWLEDGE signal...

Abstract

The invention provides a method for improving XN switching execution efficiency of an NR system, a switching method and the NR system. A redesigned Target NG-RAN node To Source NG-RAN node Transfer Control cell does not carry a code stream after a handover command Handover Command is coded, but carries a code stream after a DL-DCCH-Message message containing an RRCReceiving cell is coded, so that unnecessary ASN coding and decoding processes can be reduced, time delay in an XN process can be effectively reduced, NR system overhead is effectively reduced in a scene that multiple UE (User Equipment) are simultaneously switched, and the switching efficiency is improved. And the problems of switching failure and the like caused by overhigh overhead of the NR system are avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method for improving the execution efficiency of XN handover in an NR system, a handover method, and an NR system. Background technique [0002] The 3GPPNR wireless system 38.423 protocol defines the signaling process for UE to perform XN handover. The source base station initiates a handover request HANDOVER REQUEST to the destination base station through the XN port. After the handover command HandoverCommand is ASN encoded, the Target NG-RAN node To Source NG-RAN nodeTransparent Container information element in the HANDOVER REQUEST ACKNOWLEDGE signaling is sent to the source base station, and the handover command HandoverCommand carries the RRCReconfiguration information element to trigger the UE to perform handover. [0003] After receiving the HANDOVER REQUEST ACKNOWLEDGE signaling, the source base station decodes the Target NG-RAN node ToSource NG-RAN node...
