Description
Technical Field
The invention relates to the technical field of communication, in particular to a method and a system for improving reporting accuracy of UE (user equipment) capacity, UE and gNodeB.
Background
An Automatic Neighbor Relation (ANR) characteristic is defined in a 3GPP wireless NR system protocol, a gNodeB can issue CGI measurement to UE supporting CGI report, instruct the UE to measure an unknown neighbor, and add the unknown neighbor to the neighbor relation of a current cell according to a result reported by the UE measurement, so that the work of manually configuring the neighbor can be greatly reduced. Whether the UE supports CGI reporting or not is reported to the nodeb via the UE capability information, and the relevant capability parameters are shown in fig. 1. As shown in fig. 1, the CGI reporting capability reported by the UE is differentiated between an SA scenario and an NSA scenario. And the nr-CGI-Reporting is used for informing the gNodeB that the UE supports CGI Reporting in the SA scene, and the nr-CGI-Reporting-ENDC is used for informing the gNodeB that the UE supports CGI Reporting in the NSA scene.
The nr-CGI-Reporting capability is added before the 38.331-f40 protocol, and is commonly used for CGI Reporting capability in SA/NSA scenarios, as shown in fig. 2.
The 38.331-f50 protocol newly adds nr-CGI-Reporting-endec capability for CGI Reporting capability in NSA scenarios, and nr-CGI-Reporting is only used for SA scenarios, as shown in fig. 3.
When there is UE supporting f40 protocol and f50 protocol coexisting in the network in the SA/NSA hybrid networking scenario, if the UE capability only reports nr-CGI-Reporting but not nr-CGI-Reporting-endec, the nodeb cannot accurately identify whether the UE supports CGI Reporting capability in the NSA scenario because it cannot acquire information about whether the UE supports f40 protocol or f50 protocol:
if the UE supports the f40 protocol and the gNodeB is identified as supporting the f50 protocol, the gNodeB does not issue CGI measurement configuration to the UE in an NSA scene, so that the effective range of ANR characteristics is reduced;
if the UE supports the f50 protocol and the gnnodeb is identified as supporting the f40 protocol, the gnnodeb issues CGI measurement configuration to the UE in the NSA scenario, but the UE does not support CGI measurement at this time, which may cause various unknown results such as network resignation of the UE.

Therefore, this embodiment provides a method for improving UE capability reporting accuracy, where the method includes:
an accessstratumSubRelease cell is newly added in the UE capability of the 3GPP 38.331 protocol; the AccessStratumSubRelease cell is used for indicating the sub-version in the R15/R16 protocol version, as shown in fig. 5;
the R15/R16 protocol version and the sub-version are combined to obtain the detailed protocol version currently supported by the UE; for example:
if the cell value of AccessStratumRelease is rel15 and the cell value of AccessStratumSubRelease is subscribe 4, the detailed protocol version currently supported by the UE is f40 version;
if the value of the AccessStratumRelease cell is rel15 and the value of the AccessStratumSubRelease cell is subrel5, the detailed protocol version currently supported by the UE is the f50 version.
After the gNodeB acquires the detailed protocol version currently supported by the UE, the CGI capability reported by the UE can be accurately identified. Therefore, by optimizing the NR air interface UE capability reporting design, an Access stratum SubRelease cell is newly added in the reported UE, so that the gNodeB can accurately identify the CGI capability reported by the UE, the UE capability reporting accuracy can be improved, and the scheme can be applied to large-scale commercial use of the capability of the UE for accurately reporting the CGI capability and assisting the ANR characteristic in SA/NSA hybrid networking.
