Description

Technical Field

[0001] The present application belongs to the field of 4G / 5G communication transmission technology, and in particular, relates to a method for improving the efficiency of obtaining terminal location information. Background Art

[0002] The 3GPP 38.413 protocol stipulates that the NG port sends the information of the switching UE and the target station to the core network or the opposite base station through the HO Required message or the XN port sends the information of the switching UE and the target station to the core network or the opposite base station through the HO Required message or the XN port sends the information of the switching UE and the target station to the core network or the opposite base station through the HO Required message or the X2 port sends the information of the switching UE and the target station to the core network or the opposite base station through the HO Request message for the subsequent switching process.

[0003] However, due to the complexity and uncertainty of the wireless environment, there is a high probability of handover failure during the handover process. From the indicators and logs, the existing architecture cannot determine the location and cause of the UE that failed the handover, and cannot be further optimized to improve user perception. For handover failures in the existing network, one method is to adjust the handover parameters to observe whether the indicators have improved, and the other is to locate the specific handover failure point through manual network testing by network optimization personnel. This process requires a lot of manpower and has a high economic cost. The existing solution cannot quickly locate the location information of the handover failure point. Summary of the invention

[0004] The embodiment of the present application provides a method for improving the efficiency of obtaining terminal location information, aiming to obtain the location information of the switching UE through the switching process, and provide a reference for subsequent refined network optimization.

[0005] The technical solution adopted by the present invention is: like Figure 1 As shown, a method for improving the efficiency of obtaining terminal location information includes: a user equipment reports its own location information to a base station through signaling and data, and the base station periodically updates the location information of the user equipment, The base station configures the user equipment including the measurement configuration of the switching and the position, satisfies the measurement report of the user equipment to be fed back to the base station, and reports the measurement report, and the base station sends the switching request information to the target base station, The source station and the target base station obtain the geographical location information change of the user equipment, the information of the target base station, the wireless interface information of the user equipment and the latest geographical location of the user equipment.

[0006] Preferably, after initiating a handover request, the source station transmits the information of the target base station, the wireless interface information of the user equipment and the latest geographic location information of the user equipment to the target base station, and the interfaces include but are not limited to Ng, S1, Xn and X2.

[0007] The method specifically comprises the following steps: Step 1: The target station broadcasts in SIB1 and sends reference information, including a synchronization signal block SSB of the fifth generation mobile communication technology or a cell reference signal CRS of the fourth generation mobile communication technology; Step 2: The base station configures the UE Measurement configuration based on measurement and location information; Step 3: The UE measures the target signal and the current location information of the UE; Step 4: When the measurement report conditions are met, the UE reports the measurement results and UE location information to the base station; Step 5: The base station generates a request message based on the measurement report and the neighboring cell list and sends it to the core network or the target base station, wherein the request message includes the target station information, the wireless side information of the UE and the location information of the UE when reporting the measurement report; Step 6: Send a HO Reqired message to the core network. The request message carries the source station information including the UE location information. Step 7: AMF or MME finds the target base station through the target station information carried by the handover; Step 8: forward the handover request to the target base station and execute the subsequent handover process; Step 9: After the target base station receives the handover request, the base station records the location information in the handover request for subsequent handover MCS selection, problem troubleshooting and other preparations, and generates a handover preparation message to execute subsequent processes.

[0008] In step 6, if the interface is switched to Xn or X2, go directly to step 8.

[0009] In step six, if the source station is gNB, it is sent to AMF through the Ng port; if the source station is eNB, it is sent to MME through the S1 port.

[0010] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: Through the handover request reported by the user equipment (UE), the NG / Xn interface or the S1 / X2 interface, these requests carry data for obtaining the location information of the user equipment. With this data, the neighboring area of ​​the location information of the handover user equipment can be automatically obtained, which not only reduces the need for manual operation, but also effectively reduces costs. In this way, the market competitiveness of the product can be significantly improved, making it stand out in the fierce market competition. BRIEF DESCRIPTION OF THE DRAWINGS
