Embodiment 1

[0120] Embodiment one: if Figure 4 As shown, the NR-NR dual-connection master-slave nodes of the CU / DU separation structure are exchanged.

[0121] Step 1: The source MgNB-CU decides to initiate a handover process to change the current master node to a slave node and change the current slave node to a master node.

[0122] Step 2: The source MgNB-CU derives the access layer root key KgNB* required by the target master node, specifies a value (that is, the first value above), and then derives the root key KgNB* required by the target slave node from KgNB* combined with the value Access stratum key S-KgNB*.

[0123] Step 3: The source MgNB-CU generates measurement configuration information for the target SgNB-CU after handover, which contains an indication (ie, the above-mentioned first indication information) to indicate that the configuration information is an addition based on the source MgNB-CU measurement configuration information. Quantity configuration information.

Embodiment 2

[0138] Embodiment two: if Figure 5 As shown, the non-separated structure NR-NR dual-connection master-slave node exchange.

[0139] Step 1: The source MgNB decides to initiate a handover process to change the current master node into a slave node, and change the current slave node into a master node.

[0140] Step 2: The source MgNB derives the access layer root key KgNB* required by the target master node, specifies a value, and then derives the access layer key S-KgNB* required by the target slave node from KgNB* combined with this value .

[0141] Step 3: The source MgNB generates measurement configuration information for the target SgNB after handover, which includes an indication (such as the first indication information above) to indicate that the configuration information is incremental configuration information based on the source MgNB measurement configuration information.

[0142] Step 4: The source MgNB generates radio bearer configuration information for the tar...

Embodiment 3

[0152] Embodiment three: as Image 6 As shown, the MCG and SCG are interchanged in the dual connection scenario in the CU / DU separation structure gNB.

[0153] Step 1: The gNB-CU decides to initiate an intra-gNB handover procedure to change the current MCG to SCG and the current SCG to MCG. The current MCG is using the physical resources inside gNB-DU1, and the current SCG is using the physical resources inside gNB-DU2.

[0154] Step 2: gNB-CU sends a UE context modification request message (such as the third interface message) to gNB-DU1, which includes an instruction to reconfigure the source MCG as the target SCG (such as the fifth instruction information).

[0155] Step 3: gNB-DU1 generates the cell group configuration information of the target SCG after handover, which includes the cell group identification information of the source MCG, to indicate that the configuration information is incremental configuration information based on the source MCG configuration informati...

Abstract

The invention discloses an information sending method and device, an information receiving method and device and equipment. The method for sending the information of a first node comprises the following steps that: the first node sends at least one piece of first configuration information in an initiated first process, wherein the first configuration information comprises first indication information, the first indication information is used for indicating that the first configuration information is incremental configuration information based on current second configuration information, and identification information corresponding to the first configuration information is different from identification information corresponding to the second configuration information. According to the scheme provided by the invention, exchange operation can be carried out between the nodes in an incremental configuration manner, so that the signaling overhead is saved, unnecessary synchronous reconfiguration operation is avoided, and the interruption time delay of user plane data is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and equipment for sending and receiving information. Background technique [0002] In a wireless access system, a terminal can communicate with an access network through two or more cell groups (Cell Group). This configuration can not only improve the reliability of data transmission, but also improve the throughput of data transmission. Different cell groups have different cell group IDs (Cell Group ID). A cell group whose Cell Group ID is 0 is called a master cell group (Master Cell Group, MCG), and other cell groups are called secondary cell groups (Secondary Cell Group, SCG). [0003] like figure 1 As shown, in the E-UTRA and NR systems, RRC (Radio Resource Control) configuration information mainly includes these three types of parameters: measurement configuration, radio bearer configuration information, and cell group configuration informa...
