[0020] In order to make the purpose, technical scheme and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in detail below with reference to the drawings. It should be noted that the embodiments and features in the embodiments of the present disclosure can be combined with each other as long as they do not conflict.

[0021] ​​Currently, there can exist New Radio (NR) cells, LTE cells, eLTE (Evolved LTE) cells, Non-Standalone (NSA) cells at the same time; and there can exist 4G core network (Evolved Packet Core; EPC) and 5G core network (5th-Generation Core; 5GC) at the same time. Currently, a terminal can only obtain public gateway interface (Cell Global Identifier; CGI) information of a neighboring cell through measurement. In the face of so many networking systems, if the terminal can obtain more complete cell information and report the base station, the ANR function can play a greater value. Therefore, it is hoped that the terminal can not only obtain CGI information of a neighboring cell, but also obtain specific cell information such as slice information, voice support information, n26 interface support information, network side discontinuous reception (Discontinuous Reception; DRX) capability information, and the like.

[0022] In view of the problem that the original terminal ANR measurement can only obtain CGI information of a neighboring cell, the embodiment of the present disclosure makes the terminal perform a special ANR measurement process without changing the existing protocol process as much as possible. This makes the terminal not only obtain CGI information of a neighboring cell, but also obtain network side information such as slice information.

[0023] The first aspect, as shown in the Figure 1 The embodiment of the present disclosure provides an Auto Neighbor Relationship (ANR) measurement method, which comprises the following steps:

[0024] S01, in response to the ANR measurement configuration issued by the original base station, re-establishes with the target base station.

[0025] Specifically, after the UE (User Equipment) and the original base station and the core network device connected with the original base station complete the complete access process, the original base station will issue an event-based / periodic measurement configuration to the UE to measure the neighboring base station; after completing the measurement task, the UE will send the measurement results of the neighboring base station that meets the condition (the condition is a standard protocol, so it is not described in detail here) to the original base station in the form of a measurement report, so that the original base station issues an ANR measurement configuration according to the measurement report. That is, the target base station in step S01 refers to the base station that meets the condition in the neighboring base station after the UE measures the neighboring base station according to the event-based / periodic measurement configuration.

[0026] It should be noted that the reestablishment is a standard procedure, for example, the UE reestablishes with the 5GC base station, and the reestablishment is performed according to 3GPP TS38.304.

[0027] S02、According to the ANR measurement configuration, obtain the public gateway interface (Cell Global Identifier; CGI) information of the target base station, and the configuration information of the core network device connected by the target base station.

[0028] Specifically, in step S02, after the UE reestablishes with the target base station, the UE initiates mobility registration to the network device connected by the target base station according to its own mobility. If the core network devices connected by the target base station and the original base station are different, when the UE sends the mobility registration to the core network device connected by the target base station successfully, the core network device will feed back a registration response (RegistrationAcc) signaling to the UE. At this time, the UE can obtain the configuration information of the core network device of the target base station from the RegistrationAcc signaling. If the UE does not initiate mobility registration, it means that the core network devices connected by the target base station and the original base station are the same. At this time, the configuration information of the core network device of the target base station is the configuration information of the core network device of the original base station.

[0029] In the embodiment of the present disclosure, the UE performs ANR measurement, so that the original base station can not only obtain the CGI information of the target base station, but also obtain more configuration information of the network device connected by the target base station. In this way, the disadvantages in the prior art that the ANR measurement can only upload the obtained CGI information of the target base station to the original base station are overcome, and the method of the embodiment of the present disclosure provides more information for cell automatic networking.

[0030] In some embodiments, the configuration information of the core network device includes at least one of network slice information, network support public land mobile network (Public Land Mobile Network; PLMN) information, network tracking area identity (Tracking Area Identity; TAI) information, network voice support information, network discontinuous reception (Discontinuous Reception; DRX) support information, and N26 interface information.

[0031] In some embodiments, the ANR measurement method includes not only the above steps, but also step S03 performed after step S02, re-establishing with the original base station, and sending the target base station information and the configuration information of the core network device connected thereto to the original base station. That is, after the UE obtains the core network device information of the target base station, the UE will re-establish with the original base station again, and feed back the obtained related information of the target base station to the original base station, so that the original base station can obtain the information on the network side of the target base station through the UE.

[0032] In some embodiments, S00 can also be included before step S01, that is, performing measurement on the neighboring base station in response to the event / periodic measurement configuration issued by the original base station; according to the measurement result of the neighboring base station, a cell meeting the condition is taken as a target base station, and the measurement result of the target base station is sent to the original base station, so that the original base station sends the ANR measurement configuration according to the measurement result.

[0033] In order to clearly describe the ANR measurement method of the embodiments of the present disclosure, three exemplary schemes are given below, but it should be understood that the three exemplary schemes do not constitute a limitation on the embodiments of the present disclosure.

[0034] In one example, as shown in Figure 2 and 3 , the original base station and the target base station are connected to two different 5GC devices respectively, denoted as 5GC-1 and 5GC-2, and the original base station and the target base station are denoted as gNB-1 and gNB-2 respectively. The ANR measurement method specifically includes the following steps:

[0035] S11, the UE accesses the original base station gNB-1 and registers in the core network device 5GC-1 connected to the original base station. That is, the UE has completed the access process on gNB-1, and has completed the registration process on 5GC-1.

[0036] S12, after the UE accesses gNB-1, gNB-1 issues an event / periodic measurement configuration, and the UE performs measurement on the neighboring base station according to the measurement configuration issued by gNB-1. It should be noted that the number of neighboring base stations can be one or more, including the above-mentioned gNB-2.

[0037] S13, the UE takes the measurement result of the neighboring base station meeting the condition among the measured neighboring base stations as the target base station, and sends the measurement result of the target base station to gNB-1 in the form of a measurement report. It should be noted that gNB-2 is taken as an example for illustration.

[0038] S14, the gNB-1 sends the ANR measurement configuration of the gNB-2 to the UE, the UE receives the measurement configuration sent by the gNB-1 and saves the context information of the gNB-1.

[0039] S15, after receiving the ANR measurement configuration of the gNB-2 sent by the gNB-1, the UE performs re-establishment with the gNB-2.

[0040] S16, the UE initiates a mobility registration request to the 5GC-2, the 5GC-2 sends a registration response (RegistrationAcc) signaling to the UE after receiving the mobility request sent by the UE, the UE sends the registration completion information to the 5GC-2 after receiving the RegistrationAcc signaling sent by the 5GC-2, at the same time, the UE acquires the CGI information of the gNB-2, and acquires the configuration information of the 5GC-2 according to the RegistrationAcc signaling sent by the 5GC-2. Among them, the configuration information of the 5GC-2 includes at least one of network slice information, network supported PLMN information, network TAI information, network voice support information, network DRX support information, and N26 interface information.

[0041] S17, the UE performs re-establishment with the gNB-1, and feeds back the acquired CGI information of the gNB-2 and the configuration information of the 5GC-2 to the gNB-1.

[0042] It should be noted that the above examples are described by taking the core network device as the 5GC device as an example, and in some embodiments, the core network device can also be the EPC device. In some embodiments, the base station device can be an LTE base station or an NR base station.

[0043] In one embodiment, as shown in Figure 4 and 5 , the original base station is a 4G base station, represented by eNB, the core network connected by the base station is EPC, and the core network device is EPC device, represented by EPC; the target base station is a 5G base station, represented by gNB, the core network connected by the base station is 5GC, and the core network device is 5GC device. The ANR measurement method specifically includes the following steps:

[0044] S21, the UE accesses the original base station eNB and registers in the core network EPC device connected by the eNB. That is, the UE has completed the access process on the eNB, and has completed the registration process on the EPC device.

[0045] S22, after the UE accesses the eNB, the eNB issues event / periodic measurement configuration, and the UE performs measurement on the neighboring base station according to the measurement configuration issued by the eNB. It should be noted that, due to the difference in the type of core network connected by the eNB and gNB, the eNB is EPC and the gNB is 5GC, so the eNB issues event / periodic measurement configuration as inter-system measurement configuration, and the UE performs inter-system measurement at this time; the number of neighboring base stations can be one or more, which includes the gNB mentioned above.

[0046] S23, the UE takes the measurement result of the neighboring base station meeting the condition as the target base station, and sends the measurement result of the target base station to the eNB in the form of measurement report. It should be noted that the target base station is taken as an example for illustration.

[0047] S24, the eNB issues the ANR measurement configuration of the gNB to the UE, and the UE receives the measurement configuration issued by the eNB and saves the context information of the eNB.

[0048] S25, after receiving the ANR measurement configuration of the gNB issued by the eNB, the UE performs re-establishment with the gNB.

[0049] S26, the UE initiates a mobility registration request to the 5GC device, and after receiving the mobility request sent by the UE, the 5GC device sends a registration response (RegistrationAcc) signaling to the UE, and the UE sends the information of completing the registration to the 5GC device after receiving the RegistrationAcc signaling sent by the 5GC device, at the same time, the UE acquires the CGI information of the gNB, and acquires the configuration information of the 5GC device according to the RegistrationAcc signaling sent by the 5GC device. Among them, the configuration information of the 5GC device includes at least one of network slice information, network supporting PLMN (Public Land Mobile Network) information, network TAI (Tracking Area Identity) information, network voice support information, network DRX (Discontinuous Reception) support information, N26 interface information.

[0050] S27, the UE performs re-establishment with the eNB, and feeds back the acquired CGI information of the gNB and the configuration information of the 5GC device to the eNB.

[0051] It should be noted that in the above examples, the original base station is connected to the EPC, and the target base station is connected to the 5GC. Correspondingly, the original base station is connected to the 5GC, and the target base station is connected to the EPC. The ANR measurement method described above is also applicable. In some embodiments, the base station device can be an LTE base station or an NR base station.

[0052] In one example, as shown in Figure 6 and 7 The original base station and the target base station are connected to the same core network 5GC device, and the original base station and the target base station are represented by gNB-1 and gNB-2 respectively. The ANR measurement method specifically includes the following steps:

[0053] S31, the UE accesses the original base station gNB-1 and registers in the core network 5GC device connected to the original base station. That is, the UE has completed the access process on gNB-1, and has completed the registration process on the 5GC device.

[0054] S32, after the UE accesses gNB-1, gNB-1 issues event-type / periodic measurement configuration, and the UE performs measurement on the neighbor base station according to the measurement configuration issued by gNB-1. It should be noted that the number of neighbor base stations can be one or more, which includes the above-mentioned gNB-2.

[0055] S33, the UE selects the measurement result of the neighbor base station that meets the condition as the target base station from the measured neighbor base stations, and sends the measurement result of the target base station to gNB-1 in the form of a measurement report. It should be noted that the target base station is taken as an example of gNB-2.

[0056] S34, gNB-1 issues the ANR measurement configuration of gNB-2 to the UE, and the UE receives the measurement configuration issued by gNB-1 and saves the context information of gNB-1.

[0057] S35, after receiving the ANR measurement configuration of gNB-2 issued by gNB-1, the UE performs re-establishment with gNB-2, and the UE does not perform mobility registration at this time.

[0058] S36, the UE performs re-establishment with gNB-1 and feeds back the obtained CGI information of gNB-2 and the configuration information of the 5GC device to gNB-1.

[0059] It should be noted that in the above examples, the core network device is taken as an example of the same 5GC device. In some embodiments, the core network device can also be the same EPC device. In some embodiments, the base station device can be an LTE base station or an NR base station.
