[0131] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0132] For CPA, only the MN can initiate the PSCell condition addition process; for CPC, the PSCell condition change process can be initiated by the MN or SN, which are referred to as MN-initiated and SN-initiated CPC respectively in the following text. The CPC / CPA signaling process is similar, such as Figure 1 The CPA process is shown.

[0133] The CPA / CPC process includes the following important steps:

[0134] 1) The initiating node of the process (MN or source SN) gives the recommended candidate cells based on the latest measurement results;

[0135] 2) The MN sends an SN Addition Request message to the candidate SN(s), requesting the candidate SN(s) to reserve transmission resources;

[0136] 3) If the candidate SN(s) agree to reserve transmission resources, each candidate SN shall select the target primary and secondary cells (PSCell(s)) and the corresponding secondary cell group (SCG) cells and provide the corresponding SCG radio resource configuration feedback to the MN.

[0137] Note that the candidate SN(s) can accept or reject the recommended candidate cells provided by the MN or source SN.

[0138] 4) MN sends CPA / CPC configuration information to UE through RRCReconfiguration message, which includes SCG radio resource configuration and CPA / CPC execution conditions provided by candidate SN(s). Each execution condition includes 1 or 2 trigger conditions (i.e. CondEvent).

[0139] 5) The UE receives and saves the CPA / CPC configuration in the RRCReconfiguration message, and then starts to evaluate the execution conditions. When the execution condition corresponding to a candidate PSCell is satisfied (i.e., all 1 or 2 trigger conditions are met), the UE sends an RRCReconfigurationComplete message to the MN to indicate the selected candidate PSCell (hereinafter referred to as TargetPSCell, and the node where it is located is called TargetSN); and initiates the synchronization process to the Target PSCell.

[0140] It should be noted that the CPC / CPA process failure may be CPA Execution to wrong PSCell, CPC Execution to wrong PSCell, that is, the CPA / CPC Execution process failed or SCG failure occurred immediately after successful CPA / CPC Execution; after the failure, the suitable primary and secondary cell suitable PSCell found according to the terminal measurement results may be another PSCell in the target PSCell(s) list or not in the target PSCell(s) list at all. Specifically:

[0141] If the suitable PSCell is another PSCell in the target PSCell(s) list, it means that the UE has selected the wrong target PSCell under the target SN;

[0142] If the suitable PSCell is not in the target PSCell(s) list, it may be caused by the initiating node (MN or source SN) mistakenly providing recommended candidate cells, or the candidate SN mistakenly rejecting the recommended candidate cells.

[0143] In the prior art, the CPA / CPC candidate cells are determined based on the terminal measurement results, and this measurement occurs before the MN or SN initiates the CPA / CPC process, that is, there is a large difference between the terminal measurement results (outdated) before the CPA / CPC process and the actual cell measurement results at the time of CPA / CPCExecution failure / SCG failure, which causes the CPA / CPC process to fail. The information collected by the existing technical solutions cannot assist in judging and optimizing the CPA / CPC process failure caused by outdated terminal measurement results.

[0144] In order to solve the above problems, the present invention provides an information processing method, device, equipment and medium. The method and device are based on the same application concept. Since the method and device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0145] like Figure 2 FIG. 1 is a flow chart of an information processing method provided by an embodiment of the present invention. The method is applied to a master node MN, and the method may include:

[0146] Step 201, sending first information to a candidate secondary cell; wherein the first information is used by the candidate secondary cell to select a primary or secondary cell, and the first information includes a recommended candidate cell list provided by a node initiating a first process and a measurement time corresponding to a terminal measurement result; the first process is a CPC process for changing a conditional primary or secondary cell or a CPA process for adding a conditional primary or secondary cell; or,

[0147] Preferably, the recommended candidate cell list is arranged according to the PSCell priority or according to the probability of the terminal moving to the PSCell. Specifically, the first information may be sent to N candidate secondary cells, where N is a positive integer greater than 1.

[0148] It should be noted that during the CPC / CPA process, by sending the recommended candidate cell list provided by the node initiating the first process and the measurement time corresponding to the terminal measurement result to the candidate secondary cell, a basis is provided for the candidate secondary cell to correctly select the Target PScell(s), thereby avoiding the failure of the CPA / CPC process.

[0149] It should be noted that, for MN-initiated CPA / CPC, the first information is provided by the MN; for SN-initiated CPC, the first information is provided by the source secondary node provided by the MN.

[0150] Specifically, an SN Addition Request message is sent to the candidate secondary cell, where the SN Addition Request message includes the first information.

[0151] For SN-initiated CPC, first, the MN receives a secondary node change requirement SNChange Required message sent by the source secondary node, and the SN Change Required message includes the first information; then, the MN sends the first information to the candidate secondary cell.

[0152] Step 202: When the first process fails, receiving second information sent by the terminal, or receiving second information forwarded by a third-party node from the terminal; the second information is information recorded by the terminal after the first process fails;

[0153] It should be understood that the failure of the first process refers to the failure of the first process execution process or the occurrence of a secondary cell group failure SCG failure immediately after the process is successfully executed. It should be noted that after the first process fails, the terminal will save or record the second information.

[0154] Optionally, the second information includes one or more of the following information:

[0155] A measurement result of a first cell at the time when the first process fails, the first cell includes candidate cells and / or neighboring cells;

[0156] A cell ID of the first primary and secondary cell (suitable PSCell);

[0157] Information of the first primary and secondary cells;

[0158] The measurement result of the first primary and secondary cells;

[0159] first indication information, where the first indication information is used to indicate whether the first primary and secondary cell is in a target primary and secondary cell target PSCell(s) list, where the first primary and secondary cell is determined by the terminal based on the latest terminal measurement result when the first process fails;

[0160] Second indication information, where the second indication information is used to indicate the node that initiates the first process, such as MN-initiated and SN-initiated.

[0161] Here, the second information sent by the receiving terminal may specifically be a secondary cell group failure message SCGFailureInformation sent by the receiving terminal, and the secondary cell group failure message includes the second information.

[0162] Here, the second information from the terminal forwarded by the third-party node is received; that is, after receiving the second information sent by the terminal, the third-party node forwards the second information to the MN.

[0163] Step 203: Determine the node to be optimized according to the second information.

[0164] Step 204: perform relevant optimization processing on the node to be optimized.

[0165] It should be noted that the MN performs a preliminary analysis based on the second information to determine the node that has a problem and needs to be optimized. The specific situation is different, and the corresponding node to be optimized is also different. For specific implementation, please refer to the following embodiment section. Here, the node to be optimized is a primary node or a secondary node, where the secondary node is a source secondary node source SN or a target secondary node Target SN.

[0166] Here, after the master node determines the node to be optimized, when the node to be optimized is a secondary node, the master node transmits relevant information to the secondary node to perform optimization processing on the secondary node side related to the configuration of the first process. In this way, the optimization processing helps to shorten the time from configuration to execution of the first process, and can also avoid the failure of the CPA / CPC process caused by outdated terminal measurement results.

[0167] In an optional embodiment, the above step 204 may include:

[0168] In the case that the node to be optimized is a secondary node, third information is sent to the secondary node, and the third information is used by the secondary node to perform optimization processing on the configuration related to the first process.

[0169] Optionally, the secondary node is a source secondary node; and the third information includes the second information and one or more of the following information:

[0170] The time when CPC process is initiated;

[0171] The moment when CPC process fails;

[0172] The latest terminal measurement results when the CPC process fails;

[0173] The third indication information is used to indicate that the first primary and secondary cells are not in the second recommended candidate cell list, the second recommended candidate cell list is a recommended candidate cell list provided by the source secondary node that initiates the CPC process, and the first primary and secondary cells are determined by the terminal based on the latest terminal measurement result when the first process fails.

[0174] Optionally, the secondary node is a target secondary node; and the third information includes the second information and one or more of the following information:

[0175] When initiating the first process, the terminal measurement result carried by the node initiating the first process;

[0176] When initiating the first process, the measurement time corresponding to the terminal measurement result carried by the node initiating the first process;

[0177] The time when the first process is initiated;

[0178] The moment when the first process fails;
