Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method and system for automatically identifying base station types in an LTE network. Background Art

[0002] In the Long Term Evolution (LTE) system, the 3GPP specification defines two types of LTE base stations (eNodeBs), namely macro eNodeBs and home eNodeBs, and clarifies the calculation method of the eNB-ID and cell identity of the home eNodeB, that is, the eNB-ID of the home eNodeB is equal to the Cell Identity, and the eNB-ID of the macro eNodeB takes the high 20 bits of the Cell Identity.

[0003] Currently, in the operation and deployment of LTE networks, macro base stations and micro base stations coexist in large numbers. In terms of macro / micro base station mobility management functions under LTE networks, UE (user equipment) is required to be able to switch between macro / micro base stations. When adding neighboring cells through ANR (automatic neighbor relationship), it is impossible to automatically obtain key information about base station type and eNB-ID. The base station needs to carry Target eNB-ID in the handover request initiated to the core network (EPC, Evolved Packet Core). Currently, eNB-ID can only be derived from Cell Identity through known base station types. If the base station type cannot be obtained, it will lead to eNB-ID calculation errors. The core network will reject the handover request initiated by the base station, which will cause users to lose network and interrupt user services.

[0004] Solving this problem usually relies on manual configuration, but this cannot take advantage of ANR's low-cost solution to neighboring cell problems during rapid deployment. It not only increases labor and time costs, but is also prone to configuration errors, making it difficult to meet the needs of efficient and stable network operations. Therefore, it is urgent to propose a solution that automatically identifies base station types in ANR measurements. Summary of the invention

[0005] The present invention aims to quickly obtain the type of neighboring base stations in ANR measurement, solve the problem that the ANR (automatic neighbor relation) function cannot automatically obtain the type information of neighboring base stations, resulting in the inability to correctly derive the eNB-ID when the UE switches, which in turn causes the core network to reject the switching request, causing users to lose network and service interruption, improve the success rate of macro / micro base station switching, and realize efficient and stable operation of the LTE network.

[0006] To achieve the purpose of the present invention, the following technical solutions are adopted: A first aspect of the present invention provides a method for automatically identifying a base station type in an LTE network, comprising the following steps: The core network obtains the ECGI and base station type of each base station in the LTE network area, and saves the correspondence between the ECGI and base station type of each base station in the "ECGI-base station type" correspondence table; The serving base station turns on the ANR function and obtains the ANR measurement result reported by the UE, and obtains the neighboring base station information according to the ANR measurement result, where the neighboring base station information includes the ECGI of the neighboring base station; The serving base station carries the ECGI of the neighboring base station and initiates a request to the core network to obtain the base station type corresponding to the ECGI of the neighboring base station; After receiving the request, the core network searches for a matching record in the "ECGI-base station type" correspondence table and replies the found base station type information to the serving base station.

[0007] A further improvement is that the method for the core network to obtain the ECGI and base station type of each base station in the LTE network area includes: When each base station establishes a connection with the core network through an S1-SETUP message, it reports its own base station type information to the core network in the S1-SETUP message.

[0008] A further improvement is that after the serving base station obtains the neighboring base station information according to the ANR measurement result, the method further includes: adding the neighboring base station information to the neighboring cell list.

[0009] A further improvement is that the method further comprises the following steps: The serving base station receives the base station type information replied by the core network; The serving base station saves the received base station type information to the corresponding neighboring base station information in the neighboring cell list.

[0010] A further improvement is that the method further comprises the following steps: When the serving base station needs to hand over the UE to a neighboring base station, the eNB ID of the neighboring base station is correctly derived according to the type of the neighboring base station stored in the neighboring cell list, and is carried in a handover request message and sent to the core network.

[0011] A further improvement is that the neighboring base station information also includes the PCI and frequency of the neighboring base station.

[0012] A further improvement is that the base station types include macro base stations and micro base stations.

[0013] A second aspect of the present invention provides a system for automatically identifying base station types in an LTE network, comprising the following modules: A relationship table construction module is used to obtain the ECGI and base station type of each base station in the LTE network area through the core network, and save the correspondence between the ECGI and base station type of each base station in the "ECGI-base station type" correspondence table; A neighboring base station information acquisition module is used to enable the ANR function through the serving base station and obtain the ANR measurement result reported by the UE, and obtain the neighboring base station information according to the ANR measurement result, wherein the neighboring base station information includes the ECGI of the neighboring base station; A request module, used for initiating a request to the core network to obtain the base station type corresponding to the ECGI of the neighboring base station through the serving base station carrying the ECGI of the neighboring base station; The search and reply module is used to search for matching records in the "ECGI-base station type" correspondence table after the core network receives the request, and reply the found base station type information to the serving base station.

[0014] The third aspect of the present invention proposes an electronic device, comprising a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein when the processor executes the computer program, a method for automatically identifying a base station type in an LTE network as described in any one of the first aspects is implemented.

[0015] The fourth aspect of the present invention proposes a computer-readable storage medium, characterized in that the computer-readable storage medium includes a stored computer program, wherein when the computer program is running, the device where the computer-readable storage medium is located is controlled to execute a method for automatically identifying a base station type in an LTE network as described in any one of the first aspects.

[0016] The beneficial effects of the present invention are: The present invention effectively overcomes the defect that the traditional ANR cannot automatically obtain the key information of the neighboring cell base station type and eNB-ID when adding a neighboring cell. In the process of rapid base station deployment, there is no need to manually configure the neighboring cell base station type and eNB-ID information. Through the automatic identification mechanism of the present invention, the serving base station can quickly complete the neighboring cell configuration, greatly shortening the deployment time and improving the deployment efficiency.

[0017] The present invention can accurately identify the type of neighboring base stations, so that the base station can correctly deduce the eNB ID before switching, significantly improving the success rate of macro / micro base station switching, and reducing the switching failure caused by eNB-ID calculation errors. In addition, after the network deployment is completed, if the surrounding environment changes, such as the emergence of new neighboring cells or changes in the parameters of existing neighboring cells, the serving base station can automatically obtain the type of new neighboring base stations according to the process of the present invention again based on the ANR measurement results reported by the UE, to achieve automatic adaptation of neighboring cell relationships and self-optimization of the network, reduce the frequent intervention of manual network optimization, and reduce the operator's labor and time costs. At the same time, it reduces the user disconnection and service interruption caused by switching failures, and improves the user experience.

[0018] The present invention is applicable to base station systems, and also to base station plus repeater extended coverage systems, and is particularly applicable to distributed wireless systems, including optical fiber remote distributed systems, cable remote frequency shift repeater systems, frequency shift systems, sea area communications, low-altitude communications, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] Please refer to the attached Figure 1 -Attached Figure 3 ,like Figure 1 As shown, a first aspect of an embodiment of the present invention provides a method for automatically identifying a base station type in an LTE network, comprising the following steps: Step S1: The core network obtains the ECGI (E-UTRAN Cell Global Identifier) ​​and base station type (base station types include macro base stations and micro base stations) of each base station in the LTE network area, and saves the correspondence between the ECGI and base station type of each base station in the "ECGI-base station type" correspondence table. The "ECGI-base station type" correspondence table is used to record the mapping relationship between each ECGI and the corresponding base station type.

[0023] It can be understood that by setting up an "ECGI-base station type" correspondence table in the core network, an association mapping relationship between the ECGI of the base station and the base station type is established to provide a data basis for subsequent identification of neighboring base station types. The core network can quickly query the base station type corresponding to a certain ECGI in subsequent steps, thereby realizing automatic identification.

[0024] ECGI is a global cell identifier used to uniquely identify a cell in the LTE network. It consists of two parts: MCC (Mobile Country Code), MNC (Mobile Network Code) and eNBID (Evolved NodeB Identifier) ​​and CellID (Cell Identifier). Each base station cell has a unique ECGI. The core network is responsible for managing and controlling the resource allocation, user data transmission and network configuration of the entire network in the LTE network.

[0025] Step S2: The serving base station turns on the ANR (Automatic Neighbor Relation) function and obtains the ANR measurement results reported by the UE (user equipment, such as a mobile phone), and obtains the neighboring base station information according to the ANR measurement results, wherein the neighboring base station information includes the ECGI of the neighboring base station, the PCI (Physical Cell Identifier) ​​of the neighboring base station, and the frequency.

[0026] Specifically, after the serving base station obtains the neighboring base station information according to the ANR measurement result, the method further includes: adding the neighboring base station information to the neighboring cell list.

[0027] It can be understood that the serving base station refers to the base station that is currently providing services to the UE, and the neighboring base station refers to other base stations adjacent to the current serving base station. ANR is an automated network optimization technology used to dynamically discover and manage neighboring cell relationships. When the UE is connected to a serving base station, the serving base station will monitor the signal quality of the UE through the ANR function and collect relevant information about the neighboring base stations. The serving base station turns on the ANR function, which enables the serving base station to automatically discover and manage neighboring cells. After turning it on, the serving base station can continuously monitor the measurement information reported by the UE to prepare for subsequent processing of neighboring cell information. During the movement, the UE will continuously measure the surrounding signals and report the ANR measurement results to the serving base station. After receiving the results, the serving base station will extract the key information such as the PCI, frequency, and ECGI of the neighboring base station, and integrate this information into the neighboring cell list, and dynamically update the neighboring cell list.

[0028] Step S3: The serving base station carries the ECGI of the neighboring base station and initiates a request to the core network to obtain the base station type corresponding to the ECGI of the neighboring base station. The purpose of the request is to obtain the base station type of the neighboring base station.

[0029] It is understandable that the communication between the serving base station and the core network can be carried out through a standard LTE interface protocol (such as S1 interface). The request message includes the following fields: Request type: query base station type; Parameter: ECGI of neighboring base stations.

[0030] Step S4: After receiving the request, the core network searches for a matching record in the "ECGI-base station type" correspondence table, and replies the found base station type information to the serving base station.

[0031] It is understandable that after receiving the request sent by the service base station, the core network will extract the ECGI parameters of the neighboring base station in the request, and the core network will search for a record matching the ECGI in the "ECGI-base station type" correspondence table. If a matching record is found, the base station type information in the record will be extracted, and the core network will encapsulate the found base station type information into a response message and return it to the service base station through the interface. Through the query and reply of the core network, the service base station can accurately obtain the base station type information of the neighboring base station, thereby realizing automatic identification of the type of the neighboring base station.

[0032] In this embodiment, if Figure 2 As shown, the method in step S1 for the core network to obtain the ECGI and base station type of each base station in the LTE network area includes: When each base station establishes a connection with the core network through an S1-SETUP message, it reports its own base station type information to the core network in the S1-SETUP message.

[0033] It is understandable that in the LTE network, the S1 interface is the main interface connecting the evolved NodeB (eNB) and the core network (EPC, Evolved Packet Core). The S1-SETUP message is a standardized message format defined in the 3GPP specification.

[0034] When the base station starts or reconnects to the core network, the base station sends an S1-SETUP message to establish a connection with the core network. The S1-SETUP message carries the base station type field of the base station ECGI. After receiving the S1-SETUP message, the core network parses the fields and extracts the ECGI and base station type information of the base station. The core network stores the ECGI and base station type information in the "ECGI-base station type" correspondence table. The base station automatically reports its own ECGI and base station type information through the S1-SETUP message, reducing the workload of manual configuration. Whenever a new base station accesses the network or an existing base station reconnects, the core network can obtain the latest ECGI and base station type information in a timely manner.

[0035] Through the S1-SETUP message, the base station can automatically report its own ECGI and base station type information when establishing a connection with the core network. This method makes full use of the standard protocol mechanism of the LTE network, realizes the automatic collection and management of base station information, and provides a reliable data source for subsequent base station type identification.

[0036] In this embodiment, the following steps are also included: Step S5: The serving base station receives the base station type information replied by the core network; the serving base station saves the received base station type information to the corresponding neighboring base station information in the neighboring cell list, thereby completing the identification of the neighboring base station type.

[0037] In this embodiment, the following steps are also included: Step S6: When the serving base station needs to hand over the UE to a neighboring base station, the eNB ID of the neighboring base station is correctly derived according to the neighboring base station type stored in the neighboring cell list, and is carried in a handover request message and sent to the core network.

[0038] It is understandable that when the serving base station needs to initiate a handover operation, it is derived according to the calculation method of the macro base station and micro base station eNB-ID in the 3GPP specification based on the neighboring base station type that has been obtained and saved in the neighboring cell list. For macro base stations, eNB-ID takes the value of the upper 20 bits of Cell Identity; for micro base stations, eNB-ID is equal to Cell Identity. After the serving base station correctly calculates the eNB ID of the neighboring base station, it carries it in the handover request message and sends it to the core network to ensure that the handover request can be correctly processed by the core network, avoid the problem of handover failure due to eNB-ID error, and improve the handover success rate.

[0039] The present invention effectively overcomes the defect that the traditional ANR cannot automatically obtain the key information of the neighboring cell base station type and eNB-ID when adding a neighboring cell. In the process of rapid base station deployment, there is no need to manually configure the neighboring cell base station type and eNB-ID information. Through the automatic identification mechanism of the present invention, the serving base station can quickly complete the neighboring cell configuration, greatly shortening the deployment time and improving the deployment efficiency.

[0040] The present invention can accurately identify the type of neighboring base stations, so that the base station can correctly deduce the eNB ID before switching, significantly improving the success rate of macro / micro base station switching, and reducing the switching failure caused by eNB-ID calculation errors. In addition, after the network deployment is completed, if the surrounding environment changes, such as the emergence of new neighboring cells or changes in the parameters of existing neighboring cells, the serving base station can automatically obtain the type of new neighboring base stations according to the process of the present invention again based on the ANR measurement results reported by the UE, to achieve automatic adaptation of neighboring cell relationships and self-optimization of the network, reduce the frequent intervention of manual network optimization, and reduce the operator's labor and time costs. At the same time, it reduces the user disconnection and service interruption caused by switching failures, and improves the user experience.

[0041] A second aspect of an embodiment of the present invention proposes a system for automatically identifying base station types in an LTE network, which corresponds to a method for automatically identifying base station types in an LTE network provided in the above-mentioned embodiment of the present invention. Since a system for automatically identifying base station types in an LTE network provided in an embodiment of the present invention corresponds to a method for automatically identifying base station types in an LTE network provided in the above-mentioned embodiment of the present invention, the implementation method of the aforementioned method for automatically identifying base station types in an LTE network is also applicable to a system for automatically identifying base station types in an LTE network provided in this embodiment.

[0044] The request module is used to initiate a request to the core network to obtain the base station type corresponding to the ECGI of the neighboring base station through the serving base station carrying the ECGI of the neighboring base station.

[0045] The search and reply module is used to search for matching records in the "ECGI-base station type" correspondence table after the core network receives the request, and reply the found base station type information to the serving base station.
