Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for improving the reliability of CGI measurement based on DRX in an NR system.
Background
In a related communication scenario (such as an ANR functional scenario), the NR station needs to issue measurement configuration to the UE to query the CGI information of the neighbor cell, and according to the protocol 38.300, when the UE receives the measurement configuration message issued by the base station and indicates that the CGI information of the neighbor cell needs to be queried, an appropriate idle period needs to be scheduled so that the UE detects SIB1 of the neighbor cell to obtain the CGI information of the neighbor cell, as shown in fig. 1. In order to ensure that the UE enters the idle period, the current industry is realized by configuring a DRX cycle, in which the gNB-DU will not schedule downlink data to the UE any more, and the UE can detect SIB1 of the neighboring cell in the cycle to obtain CGI information. However, in the practical application scenario, the UE may continuously have many downlink data services with higher priority, so that even if the gNB-CU configures a DRX cycle for the gNB-DU, the gNB-DU cannot enter the DRX cycle under the condition of continuously having downlink data service scheduling, so that the UE does not have an idle cycle to detect the neighbor SIB1, cannot timely measure and report neighbor CGI information, and thus the function of the related communication scenario (such as an ANR functional scenario) is interrupted, and the reliability is greatly reduced.
Disclosure of Invention
The invention aims to provide a method for improving the reliability of CGI measurement based on DRX in an NR system, which aims to solve the problems that gNB-DU cannot enter a DRX period for a long time, UE does not have an idle period to detect neighbor SIB1, cannot measure and report CGI in time, and the function interruption of related communication scenes is caused, and the reliability and stability of the related communication scenes are improved.
The invention provides a method for improving the reliability of CGI measurement by an NR system based on DRX, which comprises the following steps:
In a UE CONTEXT SETUP/UE CONTEXT MODIFICATION flow defined in a 38.473 protocol of the 3GPP wireless system, the CGI measurement reliability is improved by adding Mandatory DRX Indication cells in DRX Cycle cells carried by UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST messages; the Mandatory DRX Indication cells are used to indicate that the configured DRX cycle is to be immediately validated.
Further, after receiving Mandatory DRX Indication cells, the gNB-DU needs to stop scheduling all downlink data services.
Further, the method for improving the reliability of CGI measurement by the NR system based on DRX comprises the following steps:
Step 1, gNB-CU enters a related communication scene flow, and issues measurement configuration of inquiring neighbor CGI to UE, wherein the measurement configuration comprises DRX period configuration;
Step 2, the gNB-CU configures a DRX period to the gNB-DU through UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST information, carries Mandatory DRX Indication cells and sends the DRX period to the gNB-DU;
Step 3, after receiving UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST information, the gNB-DU immediately takes effect of the configured DRX period, stops scheduling all downlink data service in the DRX period, and replies UE CONTEXT SETUP RESPONSE/UE CONTEXT MODIFICATION RESPONSE response information to the gNB-CU;
Step 4, since the gNB-DU stops scheduling the downlink data service, the DRX period configured for the UE in step 1 takes effect, the UE obtains the CGI information of the neighboring cell by detecting the MIB and the SIB1, and reports the CGI information of the neighboring cell to the gNB through measurement; the gNB can timely receive the CGI information of the adjacent cell, and effectively carries out subsequent flow processing of related communication scenes.
Further, in step 2, the gNB-CU sends UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST message to the gNB-DU through ASN coding; in step 3, the gNB-DU receives UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST message and performs ASN decoding first.
The invention also provides a gNB-CU which is used for adding Mandatory DRX Indication cells in DRX Cycle cells carried by UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST messages; the Mandatory DRX Indication cells are used to indicate that the configured DRX cycle is to be immediately validated.
The invention also provides an NR system for executing the method for improving the CGI measurement reliability based on DRX.
In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:
The invention can solve the problem that the gNB-DU can not enter the DRX period for a long time, the UE can not detect the adjacent cell SIB1 in the idle period and can not timely measure and report the CGI, thereby causing the function interruption of the related communication scene and increasing the reliability and stability of the related communication scene.

Therefore, the problem that the gNB-DU cannot enter the DRX period for a long time, the UE does not have an idle period to detect the adjacent cell SIB1, and cannot measure and report the CGI in time, so that the function of a related communication scene (such as an ANR function scene) is interrupted is solved, and the reliability and stability of the related communication scene (such as the ANR function scene) are improved. Further, after receiving Mandatory DRX Indication cells, the gNB-DU needs to stop scheduling all downlink data services.

Step 2, gNB-CU configures DRX period to gNB-DU through UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST message, carries Mandatory DRX Indication cell, and sends to gNB-DU (through ASN coding);
Step 3, after receiving UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST information, the gNB-DU (carrying out ASN decoding on the information) immediately takes effect of the configured DRX period, stops scheduling all downlink data service in the DRX period, and replies UE CONTEXT SETUP RESPONSE/UE CONTEXT MODIFICATION RESPONSE response information to the gNB-CU;
Step 4, since the gNB-DU stops scheduling the downlink data service, the DRX period configured for the UE in step 1 takes effect, the UE obtains the CGI information of the neighboring cell by detecting the MIB and the SIB1, and reports the CGI information of the neighboring cell to the gNB through measurement; the gNB can timely receive the CGI information of the adjacent cell, and effectively carries out subsequent flow processing of related communication scenes.

Step 2, gNB-CU configures DRX period to gNB-DU through UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST message, carries Mandatory DRX Indication cell, and sends to gNB-DU (through ASN coding);
Step 3, after receiving UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST information, the gNB-DU (carrying out ASN decoding on the information) immediately takes effect of the configured DRX period, stops scheduling all downlink data service in the DRX period, and replies UE CONTEXT SETUP RESPONSE/UE CONTEXT MODIFICATION RESPONSE response information to the gNB-CU;
Step 4, since the gNB-DU stops scheduling the downlink data service, the DRX period configured for the UE in step 1 takes effect, the UE obtains the CGI information of the neighboring cell by detecting the MIB and the SIB1, and reports the CGI information of the neighboring cell to the gNB through measurement; the gNB can timely receive the CGI information of the adjacent cell, and effectively carries out subsequent flow processing of related communication scenes.

Step 3, after receiving UE CONTEXT SETUP REQUEST/UE CONTEXT MODIFICATION REQUEST information, the gNB-DU (carrying out ASN decoding on the information) immediately takes effect of the configured DRX period, stops scheduling all downlink data service in the DRX period, and replies UE CONTEXT SETUP RESPONSE/UE CONTEXT MODIFICATION RESPONSE response information to the gNB-CU;
Step 4, since the gNB-DU stops scheduling the downlink data service, the DRX period configured for the UE in step 1 takes effect, the UE obtains the CGI information of the neighboring cell by detecting the MIB and the SIB1, and reports the CGI information of the neighboring cell to the gNB through measurement; the gNB can timely receive the CGI information of the adjacent cell, and effectively carries out subsequent flow processing of related communication scenes.
