Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, electronic device and readable storage medium for adding a neighboring cell. Background Art

[0002] In modern communication networks, handover between base stations is a key technology to ensure that terminal devices can maintain stable communication when moving at high speeds. As a terminal device moves from the coverage area of ​​one base station to the coverage area of ​​another base station, the connection of the terminal device must be switched from one base station (source base station) to another base station (target base station). Good handover performance is critical to communication quality and user experience, and neighbor relationship configuration is the core of achieving efficient base station handover.

[0003] In the prior art, the length of the base station identifier of different base stations is not uniform, and the length of the base station identifier can be 20 bits, 28 bits, 21 bits, etc. When the source base station obtains the base station identifier of the target base station through the Cell Global Identity (CGI) measurement, the length of the base station identifier obtained by the source base station is always a fixed length. Therefore, if the actual length of the base station identifier of the target base station is inconsistent with the fixed length, when the source base station uses the fixed-length base station identifier obtained through the CGI measurement to parse the base station identifier of the target base station, there will be a problem of incorrect parsing of the base station identifier of the target base station, resulting in an error in adding the cell of the target base station to the neighboring cell relationship table or the neighboring cell list of the source base station, thereby causing subsequent switching failures between the source base station and the target base station.

[0004] Therefore, in the process of adding neighboring cells, the incorrect configuration of neighboring cell relations caused by the inconsistency between the actual length of the base station identifier and the fixed length has become a problem that needs to be solved urgently. Summary of the invention

[0058] First, the terms involved in one or more embodiments of this specification are explained.

[0059] A cell, also called a service cell, refers to the area covered by a base station or part of a base station. Each cell represents a geographical area served by a base station. A base station includes at least one cell. Different cells usually use different frequency bands for signal transmission to avoid mutual interference.

[0060] Terminal equipment includes equipment that provides voice and / or data connectivity to users, such as a handheld device with wireless connection function, or a processing device connected to a wireless modem. The terminal equipment can communicate with the core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal equipment may include user equipment (UE), wireless terminal equipment, mobile terminal equipment, device-to-device communication (D2D) terminal equipment, vehicle-to-everything (V2X) terminal equipment, machine-to-machine / machine-type communications (M2M / MTC) terminal equipment, Internet of Things (IoT) terminal equipment, subscriber unit (subscriberunit), subscriber station (subscriber station), mobile station (mobile station), remote station (remotestation), access point (access point, AP), remote terminal (remote terminal), access terminal (access terminal), user terminal (user terminal), user agent (user agent), or user equipment (user device), etc. For example, it may include a mobile phone (or "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-built-in mobile device, etc. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and other devices. It also includes restricted devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as bar codes, radio frequency identification (RFID), sensors, global positioning systems (GPS), laser scanners, etc., which are not specifically limited in the embodiments of the present application.

[0061] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for the application of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-size, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0062] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU).

[0063] The embodiments of the present application also relate to network devices. The network device may be a device for communicating with a terminal device, for example, an evolved NodeB (eNB or eNodeB) in a Long Term Evolution (LTE) communication system, or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a fifth generation mobile communication (5th Generation Mobile Communication Technology, 5G) system or a network communication system after the 5G system, or a network device in a future evolved public land mobile network (PLMN), etc.

[0064] The network devices involved in the embodiments of the present application include RAN devices and core network devices. The RAN device is connected to the terminal device, and is used to receive data from the terminal device and send it to the core network device. The RAN device corresponds to different devices in different communication systems. For example, in the LTE system, it corresponds to the evolved base station eNB, and in the 5G system, it corresponds to the 5G system, such as the access network equipment in the new wireless (NewRadio, NR) communication system (for example, the next generation base station (Next Generation NodeB, gNB), central control unit (Central Unit, CU), distributed unit (Distributed Unit, DU)). The core network equipment includes the access and mobility management function (AMF) network element, which belongs to the core network network element and is mainly responsible for the signaling processing part, such as: access control, mobility management, attachment and detachment, and gateway selection and other functions.

[0065] The following is an introduction to the implementation background of the technical solution provided in the embodiments of the present application.

[0066] In modern communication networks, handover between base stations is a key technology to ensure that terminal devices can maintain stable communication when moving at high speeds. As a terminal device moves from the coverage area of ​​one base station to the coverage area of ​​another base station, the connection of the terminal device must be switched from one base station to another. The success or failure of the handover directly affects the communication quality and user experience of the terminal device. Therefore, good handover performance is crucial to the stability and reliability of the mobile communication system.

[0067] The efficiency of the handover process between the source base station (one base station) and the target base station (another base station) depends on the neighbor relationship configuration of the source base station, which can be configured manually or automatically. Automatic Neighbor Relation (ANR) is a technology that automatically configures neighbor cell relations. It can automatically collect neighbor cell information based on the communication status of the source base station and the terminal device, and add the neighbor cells to the source base station's Neighbor Relation Table (NRT) or Neighbor Cell List (NCL) to ensure the stability of the handover process.

[0068] According to different communication system types, ANR can be divided into intra-system ANR and inter-system ANR (i.e., heterogeneous system ANR). Intra-system ANR refers to the neighbor relationship configuration between the source base station and the target base station in the same communication system (such as within the LTE system), while heterogeneous system ANR involves the neighbor relationship configuration between the source base station and the target base station in different communication systems, such as the neighbor relationship configuration between the source base station in the LTE network and the target base station in the 5G NR network.

[0069] During the configuration of intra-system ANR and inter-system ANR, when the terminal device communicates with the source base station, the source base station will send a control command to the terminal device, requiring the terminal device to measure the signals of the surrounding cells and feed back the measurement results to the source base station. The source base station automatically identifies the neighboring cells and adds them to the NRT or NCL of the source base station based on the measurement results reported by the terminal device and the signal strength, quality and other indicators of the neighboring cells.

[0070] However, in the current technical implementation, there are the following problems: Whether it is the evolved base station eNB in ​​the LTE network or the next-generation base station gNB in ​​the 5G network, the base station identification length of the evolved base station identification (Evolved NodeBIdentifier, eNB ID) of different eNBs and the next-generation base station identification (Next Generation NodeBIdentifier, gNB ID) of different gNBs is not uniform. Common base station identification lengths include 20 bits, 28 bits, and 21 bits, etc. This inconsistency in base station identification length leads to the following technical problems.

[0071] In the prior art, the source base station usually obtains the base station identifier (eNB ID or gNB ID) of the target base station through the global cell identifier CGI measurement. However, no matter what the actual length of the base station identifier of the target base station is, the length of the base station identifier obtained by the source base station through CGI measurement is always a fixed length. If the actual length of the base station identifier of the target base station is inconsistent with the fixed length, when the source base station uses the fixed-length base station identifier obtained through CGI measurement to parse the base station identifier of the target base station, there will be a problem of incorrect parsing of the base station identifier of the target base station, resulting in an error in adding the cell of the target base station to the neighbor relationship table NRT or the neighbor cell list NCL of the source base station, thereby causing subsequent switching failures between the source base station and the target base station.

[0072] Therefore, in the process of adding neighboring cells, the inconsistency between the actual length of the base station identifier and the fixed length leads to the configuration error of the neighboring cell relationship, which in turn causes the failure of base station switching, which becomes an urgent problem that needs to be solved.

[0073] Based on the problems existing in the related art, the present application provides a method, device, electronic device and readable storage medium for adding a neighboring cell. In the neighboring cell adding method, first, the source base station obtains the frequency point and the first identifier of the first cell, as well as the first base station identifier and the first target identifier length of the first base station, the length of the first base station identifier is a fixed length, and the length of the first target identifier indicates the actual length of the first base station identifier; secondly, the source base station processes the first base station identifier based on the length of the first target identifier to obtain a second base station identifier that is consistent with the length of the first target identifier, avoiding the parsing error that may occur when the source base station directly parses the first base station identifier, and ensuring that the second base station identifier is the correct base station identifier of the first base station; finally, the source base station adds the first cell as a neighboring cell of the second cell of the source base station based on the frequency point and the first identifier of the first cell, as well as the second base station identifier of the first base station, to ensure that the neighboring cell relationship between the first cell and the second cell is correctly configured, and to avoid the subsequent switching failure between the source base station and the first base station due to the error in parsing the first base station identifier.

[0074] Next, some specific embodiments and drawings are used to describe in detail how the present application solves the above-mentioned problem of incorrect configuration of neighboring cell relations caused by the inconsistency between the actual length of the base station identifier and the fixed length.

[0075] Figure 1 A flowchart of a method for adding a neighboring area provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the neighboring cell adding method provided in the embodiment of the present application specifically includes S101 to S103, and S101 to S103 are described in detail below.

[0076] S101. A source base station obtains a frequency point and cell global identifier CGI information of a first cell, and a first target identifier length of a first base station to which the first cell belongs.

[0077] The frequency point of the first cell refers to the frequency resources used in the coverage area of ​​the first cell in the wireless communication network for signal transmission and communication.

[0078] It should be noted that obtaining the frequency of the first cell helps to quickly achieve uplink and downlink synchronization between the terminal device and the first cell, thereby improving the subsequent switching efficiency of the terminal device from the second cell to the first cell.

[0079] The CGI information of the first cell includes a first identifier of the first cell and a first base station identifier of the first base station.

[0080] It should be noted that the first identification of the first cell is a unique identifier of the first cell. The first identification of the first cell includes a public land mobile network identity (PLMN-Id), a location area code (Location Area Code) and a cell identity (Cell Identity) of the first cell.

[0081] It should be noted that the length of the first base station identifier is a fixed length.

[0082] The length of the first base station identifier is a fixed length specified by the design and protocol of the communication system. The fixed length can be set by the user, and this embodiment does not make any specific limitation on this.

[0083] For example, the fixed length is 28 bits.

[0084] The first target identifier length is used to indicate the actual length of the first base station identifier.

[0085] It should be noted that the lengths of the first target identifiers of different base stations may be the same or may be different.

[0086] In this embodiment, the source base station can know the actual length of the first base station identifier of the first base station by obtaining the first target identifier length of the first base station, so that the first base station can subsequently correctly parse the first base station identifier of the first base station based on the first target identifier length to obtain the second base station identifier of the first base station.

[0087] S102: The source base station processes the first base station identifier based on the first target identifier length to obtain a second base station identifier of the first base station.

[0088] The length of the second base station identifier is the same as the length of the first target identifier.

[0089] It should be noted that the source base station adjusts the first base station identifier of the first base station based on the first target identifier length to generate a second base station identifier, and the length of the second base station identifier is the actual base station identifier length of the first base station.

[0090] Specifically, the source base station may dynamically adjust the length of the first base station identifier based on the length of the first target identifier through an algorithm or rule base built into the source base station to generate a second base station identifier corresponding to the first base station identifier and having the same length as the first target identifier.

[0091] In this embodiment, the source base station can correctly generate the base station identifier (second base station identifier) ​​of the first base station by dynamically adjusting the length of the first base station identifier, so that in the subsequent neighboring cell adding process, the source base station can correctly identify the information of the first base station, ensure that the information of the first cell added to the neighboring cell relationship table NRT or the neighboring cell list NCL is accurate, and avoid the first cell added to the neighboring cell relationship table NRT or the neighboring cell list NCL due to incorrect parsing of the base station identifier of the first base station.

[0092] S103: The source base station adds the first cell as a neighboring cell of the second cell based on the frequency and the first identifier of the first cell and the second base station identifier.

[0093] The second cell is the cell of the source base station.

[0094] It should be noted that the source base station adds the information of the first cell to the neighbor relation table NRT or the neighbor cell list NCL of the second cell based on the frequency and the first identifier of the first cell and the second base station identifier.

[0095] An embodiment of the present application provides a method for adding a neighboring cell. First, a source base station obtains a frequency point and a first identifier of a first cell, as well as the first base station identifier and a first target identifier length of the first base station, wherein the length of the first base station identifier is a fixed length, and the length of the first target identifier indicates an actual length of the first base station identifier; secondly, the source base station processes the first base station identifier based on the length of the first target identifier to obtain a second base station identifier that is consistent with the length of the first target identifier, thereby avoiding possible parsing errors that may occur when the source base station directly parses the first base station identifier, and ensuring that the second base station identifier is the correct base station identifier of the first base station; finally, the source base station adds the first cell as a neighboring cell of the second cell of the source base station based on the frequency point and the first identifier of the first cell, as well as the second base station identifier of the first base station, to ensure that the neighboring cell relationship between the first cell and the second cell is correctly configured, thereby avoiding subsequent switching failure between the source base station and the first base station due to a parsing error of the first base station identifier.

[0096] It should be noted that the source base station and the first base station can be eNB or gNB, and this embodiment does not specifically limit this. That is, the neighbor cell adding method provided in this application can be applicable to ANR within the system or to ANR in different systems.

[0097] For example, when the source base station obtains that the number of bits of the first base station identifier of base station A to which cell A belongs is 28 bits and the length of the first target identifier of base station A is 20 bits, the source base station first processes the 28-bit first base station identifier to obtain the second base station identifier of base station A, and the number of bits of the second base station identifier is 20 bits; thereafter, the source base station adds cell A as a neighboring cell of cell B of the source base station based on the frequency and first identifier of cell A, and the second base station identifier of base station A.

[0098] In the above embodiment, the source base station needs to obtain the frequency point and global cell identifier CGI information of the first cell, and the first target identifier length of the first base station to which the first cell belongs. Next, a method for the source base station to obtain the frequency point and global cell identifier CGI information of the first cell, and the first target identifier length of the first base station to which the first cell belongs is described in detail.

[0099] Figure 2 A flowchart of another method for adding a neighboring area provided in an embodiment of the present application is shown below. Figure 2 As shown, in a possible embodiment, S101, the source base station obtains the frequency and global cell identifier CGI information of the first cell, and the first target identifier length of the first base station to which the first cell belongs, which can be implemented through Sa1 to Sa7. Sa1 to Sa7 are described in detail below.

[0100] Sa1. The source base station broadcasts a second system message.

[0101] The second system message includes the frequency of the second cell and the second target identifier length of the source base station. The second target identifier length is used to indicate the actual length of the base station identifier of the source base station.

[0102] It should be noted that, in actual use, the second cell of the source base station will also serve as a neighboring cell of other base stations. Therefore, in order for other base stations to correctly resolve the base station identifier of the source base station, the source base station needs to broadcast the frequency of the second cell and the second target identifier length to other base stations or terminal devices in the cell of other base stations by regularly broadcasting the second system message.

[0103] In this embodiment, the source base station broadcasts a second system message to enable other base stations or terminal devices to learn the second target identifier length of the source base station, so that other base stations can subsequently parse and obtain the correct base station identifier of the source base station, thereby ensuring that the neighboring cells of other base stations are correctly configured.

[0104] In addition, the second system message also includes second access information for the terminal device in the second cell to access the source base station. The second access information may include access authority, signal strength, load status and other information of the source base station, which is not specifically limited in this implementation.

[0105] Sa2. The terminal device in the second cell accesses the source base station based on the second access information.

[0106] It should be noted that the method by which the terminal equipment in the second cell accesses the source base station based on the second access information is an existing method and will not be described in detail in this embodiment.

[0107] Sa3. The source base station sends the first configuration information to the terminal device in the second cell. Correspondingly, the terminal device in the second cell receives the first configuration information sent by the source base station.

[0108] The first configuration information is used to instruct the terminal device to perform frequency point measurement and CGI information measurement of the first cell, and to obtain the first target identifier length.

[0109] It should be noted that when the source base station turns on ANR to add a neighboring cell, the source base station transmits the first configuration information to the terminal device in the second cell through the wireless interface, so that the terminal device can perform frequency measurement and CGI information measurement of the first cell and obtain the first target identifier length.

[0110] The method by which the terminal device performs frequency measurement and CGI information measurement of the first cell is an existing method and will not be described in detail in this embodiment.

[0111] Sa4. The terminal device in the second cell receives the first system message broadcast by the first base station.

[0112] The first system message includes the frequency of the first cell and the first target identifier length.

[0113] It should be noted that the first base station will periodically broadcast the first system message of the first base station, and the first system message includes information related to the first cell. Specifically, the first system message includes at least the frequency of the first cell and the first target identifier length.

[0114] In addition, the first system message also includes first access information for a terminal device in the first cell to access the first base station. The first access information may include access authority, signal strength, load status, and other information of the first base station, which is not specifically limited in this implementation.

[0115] The terminal equipment in the second cell can receive the first system message broadcasted by the first base station through the wireless interface, and parse and query the first system message to extract the frequency of the first cell and the first target identifier length of the first base station.

[0116] In this embodiment, the source base station receives and parses the first system message broadcast by the first base station through the terminal equipment in the second cell, accurately obtains the frequency point and the first target identifier length of the first cell, and ensures that the source base station can obtain a reliable first measurement result; at the same time, it simplifies the operation of the terminal equipment, avoids the complicated measurement process, improves the accuracy of obtaining the frequency point of the first cell and the first target identifier length of the first base station, and reduces the measurement error.

[0117] Sa5. The terminal device in the second cell generates a first measurement result based on the first system message and the CGI information of the first cell.

[0118] It should be noted that the CGI information of the first cell is obtained by the terminal equipment in the second cell performing CGI measurement on the first cell based on the CGI information measurement indication in the first configuration information.

[0119] Sa6. The terminal device in the second cell sends the first measurement result to the source base station. Correspondingly, the source base station receives the first measurement result sent by the terminal device in the second cell.

[0120] The first measurement result includes the frequency and CGI information of the first cell, and the first target identifier length.

[0121] It should be noted that the terminal device can simultaneously measure the frequency and CGI information of multiple first cells, and obtain the first target identifier length of the first base station to which each first cell belongs. Therefore, the first measurement result includes the frequency and CGI information of at least one first cell, and the first target identifier length corresponding to the first base station to which at least one first cell belongs.

[0122] After receiving the first configuration information sent by the source base station, the terminal device performs relevant measurements according to the instructions of the first configuration information.

[0123] Specifically, the terminal device first measures the frequency of at least one first cell, and then obtains CGI information of at least one first cell based on the frequency of at least one first cell, and determines the first target identifier length of the first base station to which each cell belongs.

[0124] After the terminal device obtains the frequency point and CGI information of at least one first cell and the first target identifier length of the first base station to which each first cell belongs, the terminal device packages the frequency point and CGI information of at least one first cell and the first target identifier length of the first base station to which each first cell belongs, obtains a first measurement result, and sends the first measurement result to the source base station.

[0125] In a possible implementation, when the source base station is a gNB and the first base station is an eNB, that is, in the NR network, the terminal device in the second cell reports the frequency point and CGI information of at least one first cell included in the first measurement result, and the first target identifier length of the first base station to which each first cell belongs to to the source base station in the form of a second measurement report.

[0126] The frequency and CGI information of the first cell in the second measurement report and the length of the first target identifier of the first base station may be reported in the form of: MeasResults→MeasResult List EUTRA→MeasResult EUTRA→CGI-Info EUTRA.

[0127] Among them, "MeasResults" is a field in the second measurement report, which is used to indicate the measurement results of the terminal equipment in the second cell. "MeasResults" contains specific data of various network measurements performed by the terminal equipment in the second cell, including but not limited to the frequency points and signal quality of different first cells.

[0128] "MeasResult List EUTRA" is a sub-element of "MeasResults" and is specifically used to store the measurement results of the terminal equipment in the second cell in the Evolved Universal Terrestrial Radio Access (EUTRA) network. "MeasResult List EUTRA" includes multiple measurement results of the terminal equipment in the second cell in the EUTRA network. Each measurement result may include a frequency point, identification information, signal strength, etc. of the first cell.

[0129] "MeasResult EUTRA" is an item in "MeasResult List EUTRA", and is used to indicate a measurement result of the terminal equipment in the second cell in the EUTRA network. Each measurement result specifically corresponds to the frequency point, identification information, signal strength, etc. of a first cell.

[0130] “CGI-Info EUTRA” is a field in “MeasResult EUTRA”, and is used to represent data related to CGI information, and generally includes identification information of the first cell, such as the first base station identification of the first base station, PLMN-Id, and the like.

[0131] In addition, in the present application, "CGI-InfoEUTRA" also includes a new field, namely "eNB ID Length", and "eNB ID Length" is used to indicate the actual length of the first base station identifier, namely the first target identifier length.

[0132] In another possible implementation, when the source base station and the first base station are both eNBs, that is, in an LTE network, the terminal device in the second cell reports the frequency and CGI information of at least one first cell included in the first measurement result, and the first target identifier length of the first base station to which each first cell belongs to to the source base station in the form of a third measurement report.

[0133] The frequency and CGI information of the first cell and the length of the first target identifier of the first base station in the third measurement report may be reported in the form of: MeasResults→MeasResult Neigh Cells→MeasResult List UTRA→MeasResult UTRA→cgi-Info.

[0134] The content represented by MeasResults in the third measurement report is the same as that represented by MeasResults in the second measurement report, which will not be described in detail in this embodiment.

[0135] "MeasResult Neigh Cells" is a sub-element in MeasResults, which is used to store measurement results related to neighboring cells. In the LTE system, terminal devices usually measure multiple neighboring cells, and measResult Neigh Cells is used to record the measurement information of these neighboring cells. It includes information such as signal quality, frequency, and identification of neighboring cells to help the source base station understand the situation of these neighboring cells.

[0136] "MeasResult List UTRA" is a sub-element of "MeasResult Neigh Cells" and is specifically used to store measurement results performed in the Universal Terrestrial Radio Access (UTRA) network. It lists multiple measurement results related to the first cell. MeasResult List UTRA contains multiple measurement data of the terminal equipment in the second cell on the UTRA network, especially measurement data on cell identification, frequency, signal strength, etc.

[0137] "MeasResult UTRA" is an item in "MeasResult List UTRA" and is used to represent a single measurement result of the UTRA network. Each "MeasResult UTRA" corresponds to a measurement result of a first cell, and the measurement result of the first cell records the frequency point, identification information, signal quality and other information of the first cell.

[0138] "cgi-Info" is a field in "MeasResult UTRA" and is specifically used to represent data related to the CGI information of the first cell, usually including identification information of the first cell, such as the first base station identification of the first base station, PLMN-Id, etc. In addition, in the present application, "cgi-Info" also includes the "eNB ID Length" field.

[0139] Sa7. The source base station determines the frequency and CGI information of the first cell and the first target identifier length based on the first measurement result.

[0140] It should be noted that the source base station extracts information from the first measurement result, namely, the frequency and CGI information of at least one first cell carried in the first measurement result, and the first target identifier length of the first base station to which each first cell belongs.

[0141] In the embodiment of the present application, the source base station configures the terminal device to perform frequency measurement, CGI information measurement and first target identifier length acquisition, thereby ensuring that the source base station can accurately and in real time acquire the frequency and CGI information of the first cell, as well as the first base station identifier length. Since the terminal device has strong flexibility and a wide coverage range, it can perform measurements at different locations, greatly improving the accuracy and real-time performance of the first measurement result; at the same time, it effectively reduces the burden on the source base station, avoids the source base station from over-relying on its own measurement capabilities, and improves the utilization efficiency of network resources.

[0142] In the above embodiment, the terminal device needs to send the first measurement result including the frequency point and CGI information of the first cell and the first target identifier length to the source base station. Next, the method for the terminal device to obtain the frequency point and CGI information of the first cell and the first target identifier length is described in detail.

[0143] In a possible embodiment, the frequency point and the first target identifier length of the first cell in the first measurement result are determined by the terminal device according to the first system message broadcast by the first base station.

[0144] The first system message includes the frequency of the first cell and the first target identifier length.

[0145] It should be noted that the specific content of the first system message has been described in detail in the method embodiment shown in the above Sa4, and will not be repeated in this embodiment.

[0146] In an embodiment of the present application, the source base station receives and parses the first system message broadcast by the first base station through the terminal device in the second cell, accurately obtains the frequency point and the first target identifier length of the first cell, and ensures that the source base station can obtain a reliable first measurement result; at the same time, it simplifies the operation of the terminal device, avoids the complicated measurement process, improves the accuracy of obtaining the frequency point of the first cell and the first target identifier length of the first base station, and reduces the measurement error.

[0147] In the above embodiment, the source base station needs to obtain the frequency point and global cell identifier CGI information of the first cell, and the first target identifier length of the first base station to which the first cell belongs. Next, another method for the source base station to obtain the frequency point and global cell identifier CGI information of the first cell, and the first target identifier length of the first base station to which the first cell belongs is described in detail.

[0148] Figure 3 A flowchart of another method for adding a neighboring area provided in an embodiment of the present application is shown below. Figure 3 As shown, in a possible embodiment, S101, the source base station obtains the frequency and global cell identifier CGI information of the first cell, and the first target identifier length of the first base station to which the first cell belongs, which can be implemented through Sc1 to Sc5. Sc1 to Sc5 are described in detail below.

[0149] Sc1. A source base station receives a first system message broadcast by a first base station, where the first system message includes a frequency of a first cell and a first target identifier length.

[0150] The content of the first system message broadcast by the first base station has been described in detail in the method embodiment shown in the above Sa4, and will not be repeated in this embodiment.

[0151] Sc2. The source base station determines the frequency of the first cell and the first target identifier length based on the first system message.

[0152] After acquiring the first system message broadcast by the first base station, the source base station parses and queries the first system message, and can extract the frequency of the first cell and the first target identifier length of the first base station.

[0153] Sc3. The source base station sends second configuration information to the terminal device in the second cell. Correspondingly, the terminal device in the second cell receives the second configuration information sent by the source base station.

[0154] The second configuration information is used to instruct the terminal equipment in the second cell to measure the CGI information of the first cell.

[0155] It should be noted that the source base station transmits the second configuration information to the terminal equipment in the second cell through the wireless interface, so that the terminal equipment can measure the CGI information of the first cell.

[0156] Before the source base station sends the second configuration information to the terminal device, the terminal device needs to access the source base station based on the access information broadcast by the source base station for terminal device access. Thereafter, when the source base station turns on ANR to add a neighboring cell, the source base station can send the second configuration information to the terminal device.

[0157] Sc4. The terminal equipment in the second cell measures the CGI information of the first cell and generates a second measurement result.

[0158] Sc5. The terminal device in the second cell sends the second measurement result to the source base station. Correspondingly, the source base station receives the second measurement result sent by the terminal device in the second cell.

[0159] The second measurement result includes CGI information of the first cell.

[0160] It should be noted that the terminal device can measure the CGI information of multiple first cells at the same time. After receiving the second configuration information sent by the source base station, the terminal device performs CGI information measurement according to the instruction of the second configuration information, and packages the CGI information of at least one first cell obtained by measurement to obtain a second measurement result, and sends the second measurement result to the source base station.

[0161] Sc6. The source base station determines the CGI information of the first cell based on the second measurement result.

[0162] It should be noted that the source base station extracts information in the second measurement result, that is, CGI information of at least one first cell carried in the second measurement result.

[0163] In an embodiment of the present application, the source base station directly obtains the frequency of the first cell and the first target identifier length of the first base station through the first system message broadcast by the first base station, and then obtains the CGI information of the first cell through the terminal device. Different from the above-mentioned method in which the source base station obtains the frequency and CGI information of the first cell and the first target identifier length through the terminal device, the method of the embodiment of the present application relies on the direct acquisition of the source base station when obtaining the frequency of the first cell and the first target identifier length of the lower base station, rather than through the terminal device in the second cell, which reduces the dependence on the terminal device, thereby effectively improving the stability and efficiency of the neighboring cell adding operation.

[0164] In the above embodiment, the source base station needs to add the first cell as a neighboring cell of the second cell based on the frequency point and the first identifier of the first cell, and the second base station identifier. Next, the specific process of the source base station adding the first cell as a neighboring cell of the second cell based on the frequency point and the first identifier of the first cell, and the second base station identifier is described in detail.

[0165] In a possible embodiment, S103, the source base station adds the first cell as a neighboring cell of the second cell based on the frequency and the first identifier of the first cell and the second base station identifier, which can be implemented through Sd1. Sd1 is described in detail below.

[0166] Sd1. The source base station adds the frequency point and the first identifier of the first cell, and the second base station identifier to the neighbor cell relationship table NRT or the neighbor cell list NCL of the second cell based on the frequency point and the first identifier of the first cell, and the second base station identifier.

[0167] The neighbor relation table NRT is a data structure used to store the neighbor configuration information of the base station. Each base station has a neighbor relation table NRT, which records the neighbor relation between the cell under the jurisdiction of the base station and other cells. The neighbor relation table NRT usually includes the identifier of each neighbor, the frequency of the neighbor, the CGI information of the neighbor, the identifier of the base station to which the neighbor belongs, etc.

[0168] As a management tool for base stations, the Neighbor Relationship Table (NRT) contains comprehensive configuration information related to neighboring cells, helping base stations make decisions in terms of handover, resource management, load balancing and interference management.

[0169] The neighbor cell list NCL is a data structure used to store all neighbor cell information known to the base station. Each base station maintains a local neighbor cell list NCL, which lists the identification information, frequency, CGI, and identification of the base station to which the cell belongs of other cells related to it.

[0170] The neighbor cell list NCL is mainly used to support the base station to quickly access neighbor cell information in operations such as handover and load balancing. The neighbor cell list NCL usually includes relatively concise content, and its main purpose is to help the base station make decisions quickly in actual operations, such as handover selection and interference management.

[0171] It should be noted that the method in which the source base station adds the frequency point and the first identifier of the first cell, and the second base station identifier to the neighbor cell relationship table NRT or the neighbor cell list NCL of the second cell based on the frequency point and the first identifier of the first cell, and the second base station identifier is an existing method and will not be repeated in this embodiment.

[0172] In an embodiment of the present application, in an embodiment of the present application, the source base station adds the first cell to the neighbor relationship table NRT or the neighbor cell list NCL of the second cell based on the frequency and the first identifier of the first cell and the second base station identifier of the first base station, which can effectively ensure that the neighbor relationship configuration between the first cell and the second cell is accurate, and avoid subsequent switching failure when the terminal device switches from the source base station to the first base station due to incorrect configuration of the second cell.

[0173] In the above embodiment, after the source base station adds the first cell as a neighboring cell of the second cell, the source base station can switch the base station connected to the terminal device in the second cell from the source base station to the target base station. Next, a method for the source base station to switch the base station connected to the terminal device in the second cell from the source base station to the target base station is described in detail.

[0174] like Figure 2 or Figure 3 As shown, in a possible embodiment, after S103, the source base station adds the first cell as a neighboring cell of the second cell based on the frequency and CGI of the first cell and the second base station identifier, the neighboring cell adding method also includes S104 to S108, and S104 to S108 are described in detail below.

[0175] S104. The source base station receives a first measurement report sent by a terminal device in the second cell.

[0176] The first measurement report includes a signal quality measurement result of at least one first cell.

[0177] It should be noted that the signal quality measurement result includes information such as signal strength and signal quality of at least one first cell.

[0178] Before the method shown in S104, the source base station needs to send third measurement configuration information to the terminal equipment in the second cell, where the third measurement configuration information is used to instruct the terminal equipment in the second cell to perform terminal equipment switching measurement.

[0179] Before the source base station receives the first measurement report sent by the terminal device in the second cell, the source base station needs to send third measurement configuration information to the terminal device in the second cell, where the third measurement configuration information is used to instruct the terminal device in the second cell to perform terminal device switching measurement.

[0180] Among them, the switching measurement refers to the measurement operation that the terminal equipment in the second cell needs to perform. The purpose of performing the switching measurement is for the source base station to determine whether to control the terminal equipment in the second cell to switch from the second cell to the third cell (target cell).

[0181] S105. The source base station determines a first cell with the best signal quality among the at least one first cell as a third cell.

[0182] The source base station extracts the signal quality measurement result of at least one first cell from the first measurement report, and selects the first cell with the best signal quality (such as the highest signal strength) as the third cell (target cell), which can provide the best service quality for the terminal device.

[0183] It should be noted that the method in which the source base station analyzes the signal quality measurement results of multiple first cells to obtain the first cell with the best signal quality is an existing method and will not be described in detail in this embodiment.

[0184] S106: The source base station sends a switching requirement message to the centralized control device. Correspondingly, the centralized control device receives the switching requirement message sent by the source base station.

[0185] Among them, the centralized control device can be a mobility management entity (Mobility Management Entity, MME) or a fifth-generation core network (5G Core Network, 5GC).

[0186] When the source base station is an eNB, the centralized control device is the MME or 5GC. In the LTE network, the MME undertakes important signaling tasks, including access requests, handover control, and location updates of terminal devices.

[0187] When the source base station is a gNB, the centralized control device is 5GC. In the 5G network, 5GC replaces the traditional MME and provides similar control functions such as user plane data management, session management, access control, etc.

[0188] The switching request message is used to request that the terminal equipment in the second cell be connected to the second base station to which the third cell belongs.

[0189] It should be noted that the handover requirement message is a HANDOVER REQUIRED message. The HANDOVER REQUIRED message is a control message in a mobile communication network, and is mainly used to notify a target base station to perform resource preparation, communication configuration, and handover operations during a handover between base stations.

[0190] The HANDOVER REQUIRED message includes the information required by the target base station so that the target base station can allocate appropriate resources to the terminal device and ensure the smooth completion of the handover process.

[0191] Specifically, the HANDOVER REQUIRED message includes source base station information, target base station information, terminal device information, handover related parameters and additional information.

[0192] The source base station information includes the base station identifier of the source base station (eNB ID or gNB ID) and some related information; the target base station information includes the second base station identifier of the target base station, and the resource requirements or capability information of the target base station; the terminal equipment information includes the terminal equipment identifier, status, required service quality and other information; the switching related parameters include frequency, time slot, service quality requirements and other information; the additional information includes some parameters used for switching optimization, such as the frequency bands supported by the target base station, whether to use different wireless access technologies (such as switching from LTE to NR), etc.

[0193] The necessary switching information is transmitted between base stations through the HANDOVER REQUIRED message, which can ensure smooth transfer from one base station to another, help reduce delays and losses during switching, and improve the user's communication quality.

[0194] S107: The source base station receives a first response message sent by the centralized control device.

[0195] Figure 4 A flow chart of a base station switching method provided in an embodiment of the present application. Figure 4 As shown, in S107, the source base station receives the first response message sent by the centralized control device, which can be achieved through Se1 to Se6, and Se1 to Se6 are described in detail below.

[0196] Se1, the centralized control device sends a handover request (HANDOVER REQUEST) message to the second base station (target base station). Correspondingly, the second base station receives the handover request message sent by the centralized control device.

[0197] After receiving the switching request message sent by the centralized control device, the second base station determines whether the third cell of the second base station allows the terminal device in the second cell to access.

[0198] Se2. The second base station determines whether the third cell of the second base station allows the terminal equipment in the second cell to switch from accessing the second cell to accessing the third cell.

[0199] If the third cell of the second base station allows the terminal equipment in the second cell to switch from accessing the second cell to accessing the third cell, the target base station executes Se3; if the third cell of the second base station does not allow the terminal equipment in the second cell to switch from accessing the second cell to accessing the third cell, the target base station executes Se4.

[0200] Se3: The second base station sends a handover request confirmation (HANDOVER REQUESTACKNOWLEGE) message to the centralized control device. Correspondingly, the centralized control device receives the handover request confirmation message sent by the second base station.

[0201] In the case where the third cell of the second base station allows the terminal equipment in the second cell to switch from accessing the second cell to accessing the third cell, the second base station sends a switching request confirmation message to the centralized control device.

[0202] The handover request confirmation message includes radio resource control (RRC) configuration information of the third cell.

[0203] It should be noted that the RRC configuration information includes at least an identifier of the third cell and information required for accessing the third cell.

[0204] After the centralized control device receives the handover request confirmation message sent by the second base station, the centralized control device executes Se5.

[0205] Se4. The second base station sends a handover preparation failure message to the centralized control device. Correspondingly, the centralized control device receives the handover preparation failure message sent by the second base station.

[0206] When the third cell of the second base station does not allow the terminal equipment in the second cell to switch from accessing the second cell to accessing the third cell, the second base station sends a handover preparation failure (HANDOVERPREPARATION FAILURE) message to the centralized control device, and the handover preparation failure message is used to indicate that the third cell of the second base station does not allow the terminal equipment in the second cell to access.

[0207] After the centralized control device receives the handover preparation failure message sent by the second base station, the centralized control device executes Se6.

[0208] Se5. The centralized control device sends a first response message (HANDOVER COMMANG) to the source base station. Correspondingly, the source base station receives the first response message sent by the centralized control device.

[0209] The first response message is used to instruct the source base station to control the terminal device in the second cell to access the second base station.

[0210] Se6. The centralized control device sends a second response message to the source base station. Correspondingly, the source base station receives the second response message sent by the centralized control device.

[0211] The second response message is used to instruct the third cell of the second base station to reject access by terminal equipment in the second cell.

[0212] S108. The source base station sends an RRC reconfiguration message to the terminal equipment in the second cell, so that the terminal equipment in the second cell accesses the second base station based on the RRC configuration information.

[0213] The RRC reconfiguration message includes RRC configuration information.

[0214] It should be noted that after the centralized control device sends the second response message to the source base station, the source base station sends an RRC reconfiguration message to the terminal device in the second cell, so that after the terminal device in the second cell receives the RRC reconfiguration message sent by the source base station, the terminal device in the second cell switches to the third cell based on the RRC configuration information, thereby completing the switching of the terminal device in the second cell from the first base station to the second base station.

[0215] In an embodiment of the present application, through coordination between the source base station and the centralized control device, the terminal device can be efficiently switched from the source base station to the second base station with high accuracy and efficiency, effectively reducing the network impact of the terminal device due to switching delays, while optimizing the utilization of wireless resources and the overall performance of the network.

[0216] Figure 5 This is a schematic diagram of the structure of a neighboring area adding device provided in an embodiment of the present application. Figure 5 As shown, the neighbor cell adding device 500 provided in this embodiment can exist independently and be used to implement the operations corresponding to the source base station in the above method embodiment.

[0217] The neighbor cell adding device 500 may include: a transceiver module 501 and a processing module 502. The processing module 502 is used for data processing, and the transceiver module 501 may implement corresponding communication functions. The transceiver module 501 may also be called a communication interface or a communication unit.

[0218] Optionally, the neighbor cell adding device 500 may also include a storage unit, which can be used to store instructions and / or data, and the processing module 502 can read the instructions and / or data in the storage unit so that the neighbor cell adding device 500 implements the steps implemented by the source base station in the aforementioned method embodiment.

[0219] The transceiver module 501 is used to perform the reception-related operations of the source base station in the above method embodiment, and the processing module 502 is used to perform the processing-related operations of the source base station in the above method embodiment.

[0220] Optionally, the transceiver module 501 may include a sending module and a receiving module. The sending module is used to perform the sending operation in the above method embodiment. The receiving module is used to perform the receiving operation in the above method embodiment.

[0221] It should be noted that the neighboring cell adding device 500 may include a sending module but not a receiving module. Alternatively, the neighboring cell adding device 500 may include a receiving module but not a sending module. Specifically, it may depend on whether the above solution executed by the neighboring cell adding device 500 includes a sending action and a receiving action.

[0222] As an example, the neighboring area adding device 500 is used to perform the above Figure 1 Actions performed by the source base station in the illustrated embodiment.

[0223] The neighbor cell adding device 500 may include: a processing module 502 .
