Abstract

The invention discloses a user equipment information reporting and processing method, device and medium, and the method comprises the steps that user equipment records user equipment information, wherein the user equipment information comprises one or a combination of the following information: auxiliary node information, auxiliary cell information, wave beam information, cell-level measurement result information, wave beam-level measurement result information and historical information of user equipment in an inactive state; and the user equipment reporting the user equipment information. Andthe network side determines the state of the user equipment according to the user equipment information. By adopting the invention, the user equipment information can adapt to the application requirements in various scenes. And the network side can be further assisted to determine geographical positions such as paths and speeds of the user equipment, or the network side is assisted to subsequently configure auxiliary nodes and/or auxiliary cells for the user equipment according to the historical information.

Example Embodiment

[0138]Example 1:

[0139]Figure 5 It is a schematic diagram of a UE in a multiple/dual connectivity architecture. As shown in the figure, the UE is in a multiple/dual connectivity architecture while maintaining connections with the MN and SN. As shown in the figure, it is assumed that both UE1 and UE2 use Cell1 as the primary cell. If UE1 is under the common coverage of Cell1 and Cell3, UE1 can establish dual connections with Cell1 and Cell3 (the base station where it is); and UE2 is under the common coverage of Cell1 and Cell2, then UE2 can communicate with Cell1 and Cell2 (the base station where it is). ) Establish a dual connection.

[0140]The UE history information of LTE only includes the information of the primary serving cell, that is, for UE1 and UE2, the records in the current state are the cell identity of Cell1 and the respective access time. The secondary node information may include secondary node identification, access time, etc. The secondary node identifier may be the PSCell identifier of the primary and secondary cell that the UE accesses for the secondary node, and may further be in the form of CGI or frequency point+PCI.

[0141]If the secondary node information is introduced, the more detailed location information of UE1 and UE2 can be further distinguished according to the coverage area of the secondary node, so as to provide assistance for the network side to determine the UE path/speed and other information, or the secondary SN node is the subsequent SN of the UE The decision basis for the selection of the lower cell to provide historical information.

[0142]2. Implementation of recording secondary cell information on the terminal side.

[0143]In implementation, the secondary cell information includes a cell identity and/or UE access time.

[0144]In implementation, the secondary cell identifier is the frequency point of the secondary cell access + PCI.

Example Embodiment

[0145]Example 2:

[0146]In the CA architecture, the UE can send and receive data from multiple cells. Among them, the cell that has a control plane signaling connection with the UE is the primary cell, and the other cells are only used to send and receive data to improve the UE throughput and peak rate, which are called secondary cells.

[0147]The secondary cell and the primary cell can be at the same node or at different nodes. Even when the secondary cell and the primary cell belong to the same base station, the deployment of the radio frequency unit of the secondary cell can be geographically different from the radio frequency unit of the primary cell, which is called remote radio.

[0148]Therefore, for the record of UE history information, the UE may also report the record related to the secondary cell, including cell identification and access time, etc., to assist the network side in determining the UE path/speed and other information. The identifier of the secondary cell may be in the form of the frequency point of the secondary cell access + PCI.

[0149]Furthermore, based on multiple connections, the UE can also record and report for the secondary cell of the MN and/or SN node.

[0150]If the secondary cell information is introduced, the more detailed location information of the UE can be further distinguished according to the coverage of the secondary cell, and the network side can assist in determining the UE path/speed and other information, or the auxiliary MN/SN node is the subsequent MN of the UE The judgement basis for selecting and providing historical information in the secondary cell under /SN.

[0151]3. Implementation of recording beam information on the terminal side.

[0152]In implementation, the beam information recorded by the beam information is that of the primary cell and/or secondary cell of the MN when the UE is connected to the NR node, and the corresponding cell has beam division. Beam information, and/or, the beam information of the primary cell and/or secondary cell under the SN; or,

[0153]The beam information recorded by the beam information is the beam of the cell where the UE resides when the UE is in an idle state or in an inactive state, and when the UE resides in an NR cell and the cell has beam division. information.

[0154]In implementation, the beam information includes one or a combination of the following information: beam index, access time of the UE in each beam, and residence time of the UE in each beam.

Example Embodiment

[0155]Example 3:

[0156]In the NR system, beam (beam) is introduced on the basis of the cell. A cell can use different amounts of beam information according to different frequency locations and actual service conditions. The beam information is related to the direction, and the coverage areas of adjacent beams may partially overlap. On the cell-level record, the UE can also record information related to the beam direction, including the beam index, and the relevant access/resident time of the UE in each beam.

[0157]For example, the beam related information can be recorded in the following manner:

[0158]1) The UE enters the initial access/camping beam of the current cell, which may also include the time in the beam; or,

[0159]2) All beams that the UE has accessed/camped on after entering the current cell may also include the accumulated time of each beam; or,

[0160]3) The UE records all the beam information passed by the UE in chronological order, and may also include the time to access/stay on each beam.

[0161]When the UE is in the connected state, if there is a connection with the NR node, and if the corresponding cell has beam division, beam related information can be recorded for the primary cell and/or secondary cell under the MN and/or SN. For example, when the UE in the EN-DC scenario, if the SN node is configured with beam division, the UE can record beam-related information for each serving cell of the SN node (may include the primary and secondary cells PSCell and the secondary cell SCell), such as SSB identification, etc. .

[0162]When the UE is in an idle state/inactive state, if it camps on an NR cell and the cell has beam division, the UE can record the beam information of the camped cell.

[0163]4. Implementation of the measurement result information recorded on the terminal side.

[0164]In implementation, the cell-level measurement result information includes one or a combination of the following information:

[0165]Cell ID, UE's access time, UE's residence time, UE's best measurement result during UE's access, UE's best measurement result during its stay, UE's best measurement result during its access time, UE's stay The time when the best measurement result appears during the stay.

[0166]In implementation, the beam-level measurement result information includes one or a combination of the following information:

[0167]Cell ID, beam ID, UE access beam time, UE stayed beam time, UE's best measurement result during beam access, UE's best measurement result during beam access, UE's best beam access period The time when the measurement result appears, and the time when the optimal measurement result appears during the UE stays on the beam.
