A method, apparatus, and readable storage medium for configuring base station network slices.

Abstract

This application provides a method, apparatus, and readable storage medium for configuring a base station network slice. The base station generates first link establishment request information where the requested interface identifier in the requested slice information meets the acquisition conditions. Based on the first link establishment request information's request interface identifier meeting the acquisition conditions, the management network element obtains locally supported target slice information and its target interface identifier, and sends the target interface identifier to the base station. The base station then configures the slice information based on the target interface identifier. Since the target interface identifier received by the base station is automatically provided by the management network element and represents the interface identifier of the slice information supported by the management network element, compared to manual configuration which requires searching and manual input, the base station's slice information configuration based on the target interface identifier provided by the management network element is more accurate and faster.

Description

Technical Field

[0001] This application relates to the field of information technology, and more specifically, to a method, apparatus and readable storage medium for configuring base station network slices. Background Technology

[0002] Network slicing is an on-demand networking method that allows operators to separate multiple virtual end-to-end networks on a unified infrastructure. Each network slice is logically isolated from the radio access network to the bearer network and then to the core network. Examples include high-bandwidth slices, high-connectivity slices, and low-latency slices to adapt to the requirements of various diverse business application scenarios. However, network slicing requires unified coordination and configuration among various network elements. Therefore, the configuration management of slices is particularly important to fully guarantee the reliability and usability for different types of users.

[0003] In existing technologies, base station slicing management involves manual operation and maintenance of slice information, configuring slice information data according to the plan. This process requires maintenance personnel to search and manually configure, which is inefficient. Moreover, since there are many network slicing scenarios, the configuration information varies for different scenarios. Manual configuration may lead to configuration anomalies due to uncertainty or manual input errors, resulting in the risk of abnormal user access and service interruption, seriously affecting user experience and perception.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] Figure 1 The diagram illustrates exemplary system architectures of some embodiments of the base station network slicing configuration method or apparatus for which the present application can be applied.

[0059] like Figure 1 As shown, the system architecture may include a base station 101 and a core network 102. The core network 102 and the base station 101 can be connected via a wireless network. Various types of data, such as messages, requests, and instructions, can be transmitted between the base station 101 and the core network 102.

[0060] Base station 101, also known as a public mobile communication base station, is an interface device for mobile devices to access the Internet. It is also a type of radio station, referring to a radio transceiver station that transmits information between a mobile communication switching center and a mobile phone terminal within a certain radio coverage area. Base station 101 can support at least one mobile communication technology from various generations, such as: 3G, 4G, 5G, and 6G base stations.

[0061] The core network (CN) 102 can be the core network of at least one of the mobile communication technologies of various generations, such as the core network of third-generation (3G), fourth-generation (4G), fifth-generation (5G), and sixth-generation (6G). The core network 102 is one of the three main components of a mobile communication network (access network, bearer network, and core network), and it is primarily responsible for data processing and distribution. The core network 102 can include multiple network elements (NEs), which are network unit entities with specific functions, and can be referred to as core network control modules. For the 5G core network, its main network elements include Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF). The main tasks performed by the AMF include: Non-Access Stratum (NAS) signaling terminal, NAS signaling security, access stratum security control, inter-core network node signaling for mobility between 3GPP access networks, idle mode UE reachability (including paging retransmission control and execution), registration area management, supporting intra-system and inter-system mobility, access authentication, access authorization (including roaming permission checks), mobility management control (subscriptions and policies), supporting network slicing and SMF selection, etc. Because the AMF can be responsible for supporting intra-system and inter-system mobility, therefore... Figure 1 The core network 102 shown includes an AMF. That is, the base station 101 communicates with the AMF to implement the base station network slice configuration method or apparatus of this application.

[0062] It should be understood that Figure 1 The number of base stations 101 and core network 102 shown is merely illustrative. Depending on implementation needs, there can be any number of base stations 101 and core network 102.

[0063] like Figure 2 The flowchart shown is a method for configuring base station network slices according to embodiment 1 of this application. The method is applied to the management network element (AMF) and includes the following steps:

[0064] Step S201: Receive the first link establishment request information sent by the base station;

[0065] Specifically, when a base station requests to establish a link with the core network, it sends a link establishment request message to the AMF.

[0066] Specifically, the chain establishment request information is the NGSETUP REQUEST information.

[0067] If the base station requests to establish a link for the first time, it sends a first link establishment request to the AMF. The first link establishment request carries the request interface identifier corresponding to the slice information requested by the base station.

[0068] The request interface identifier is a unique identifier corresponding to the relevant information element of the request slice. Specifically, it can be unique information such as the IE (element id, the id attribute of the Element interface represents the identifier of the element, which corresponds to the global attribute id), the ST (skew detecting) code, and the SD (skew tolerant) code of the requested slice information.

[0069] Specifically, the connection establishment request information sent by the base station to the AMF also carries other information, such as location information, the base station's own IP address, port number, etc.

[0070] Step S202: Analyze the first link establishment request information to obtain the request interface identifier of the request slice information;

[0071] Specifically, after receiving the first link establishment request information sent by the base station, the first link establishment request information is analyzed to obtain the request interface identifier of the request slice information carried therein.

[0072] After analyzing and obtaining the requested interface identifier, it is determined whether the acquisition condition is met, that is, whether the condition for obtaining the interface identifier from the local machine can be triggered.

[0073] If the request interface identifier carried in the first link establishment request information is empty, the AMF cannot establish a link for the base station based on the empty request interface identifier, that is, the request interface identifier carried in the first link establishment request information does not meet the agreed link establishment conditions. However, it can trigger the operation of obtaining the interface identifier from the AMF locally, that is, the request interface identifier is empty and the acquisition condition is met; otherwise, the acquisition condition is not met.

[0074] Specifically, the agreement stipulates that the connection establishment condition is that the request interface identifier carried in the connection establishment request information meets the communication protocol, which may be the 3GPP protocol.

[0075] Step S203: Based on the fact that the requested interface identifier meets the acquisition conditions, obtain the target interface identifier of the target slice information;

[0076] The target slice information is the slice information supported by the management network element.

[0077] The AMF stores the slice information of the slices it supports.

[0078] If the requested interface identifier is empty in the connection establishment request information received from the base station, the acquisition condition is met. Part or all of the slice information is obtained from the supported slice information stored locally as the target slice information, and the target interface identifier corresponding to the target slice information is obtained.

[0079] Step S204: Send the target interface identifier to the base station so that the base station can configure slice information based on the target interface identifier.

[0080] Since the AMF sends the target interface identifier corresponding to the target slice information it obtains to the base station, the slice information configured by the base station based on the target interface identifier must be a slice supported by the AMF.

[0081] The base station configures slice information based on the received target interface identifier, and can establish a link with the corresponding target slice based on the configured slice information.

[0082] It should be noted that if the base station cannot guarantee that the requested slice information can be successfully established when requesting link establishment, it may lead to link establishment failure. Therefore, in this scheme, the first link establishment request information sent by the base station when it first requests link establishment carries an empty request interface identifier to trigger the AMF to provide the base station with the target interface identifier corresponding to its own target slice information, and feeds back the target interface identifier to the base station. The slice corresponding to the target interface identifier received by the base station is one that the base station can successfully establish a link with. Therefore, the base station can ensure that the network slice configuration can be successfully established by configuring based on the received target interface identifier.

[0083] In summary, this embodiment provides a method for configuring a base station network slice. The base station generates a first connection establishment request information where the requested interface identifier in the request slice information meets the acquisition conditions. The management network element, based on the fact that the requested interface identifier in the first connection establishment request information meets the acquisition conditions, obtains locally supported target slice information and its target interface identifier, and sends the target interface identifier to the base station. The base station then configures the slice information based on the target interface identifier. Since the target interface identifier received by the base station is automatically provided by the management network element and represents the interface identifier of the slice information supported by the management network element, compared to manual configuration which requires searching and manual input, the base station's configuration of slice information based on the target interface identifier provided by the management network element is more accurate and faster.

[0084] like Figure 3 The flowchart shown is a second embodiment of a method for configuring a base station network slice according to this application. The method includes the following steps:

[0085] Step S301: Receive the first link establishment request information sent by the base station;

[0086] Step S302: Analyze the first link establishment request information to obtain the request interface identifier of the request slice information;

[0087] Step S303: Based on the fact that the requested interface identifier meets the acquisition conditions, obtain the target interface identifier of the target slice information;

[0088] Steps S301-303 are the same as steps S201-203 in Example 1, and will not be described again in this example.

[0089] Step S304: Generate a chain establishment failure message;

[0090] If the request interface identifier in the first chain establishment request information is empty, then the empty request interface identifier is not consistent with the interface identifier of the slice information supported by the AMF. It can be determined that the request slice information corresponding to the first chain establishment request information does not meet the agreed chain establishment conditions. Therefore, the chain establishment based on the first chain establishment request information fails.

[0091] Correspondingly, a chain establishment failure message is generated.

[0092] Specifically, the chain establishment failure message is an NGSETUP FAILURE message.

[0093] The chain establishment failure message also carries information about the reason for the chain establishment failure, specifically using the cause value. For example, in this solution, the cause value for the first chain establishment request information is 1. Of course, the cause value for the chain establishment failure can be set according to the actual situation. This application does not restrict the value of the cause corresponding to the chain establishment failure.

[0094] Step S305: Generate first feedback information based on the target interface identifier and the connection establishment failure message;

[0095] In the event of a chain establishment failure, a chain establishment failure message is generated. The AMF will then add this chain establishment failure message to the obtained target interface identifier to generate the first feedback information.

[0096] Step S306: Send the first feedback information to the base station so that the base station can configure slice information based on the target interface identifier in the first feedback information.

[0097] The generated first feedback information is sent to the base station. After receiving the first feedback information, the base station can determine that the connection establishment has failed based on the connection establishment failure information carried therein, and configure itself based on the target interface identifier carried therein.

[0098] In practice, after receiving the first feedback information, the base station first analyzes the confirmed link establishment failure information to determine the link establishment failure, and then obtains the target interface identifier for configuration.

[0099] In summary, the method for configuring a base station network slice provided in this embodiment includes: generating a link establishment failure message; generating first feedback information based on the target interface identifier and the link establishment failure message; and sending the first feedback information to the base station, so that the base station configures slice information based on the target interface identifier in the first feedback information. Since link establishment failure requires feedback of link establishment failure information to the base station, this solution sends the target interface identifier along with the link establishment failure information to the base station. This ensures that the base station receives an accurate target interface identifier without significantly increasing the data transmission volume between the base station and the AMF (Application-Based Function).

[0100] like Figure 4 The flowchart shown is a third embodiment of a method for configuring a base station network slice according to this application. The method includes the following steps:

[0101] Step S401: Receive the first link establishment request information sent by the base station;

[0102] Step S402: Analyze the first link establishment request information to obtain the request interface identifier of the request slice information;

[0103] Step S403: Based on the fact that the requested interface identifier meets the acquisition conditions, obtain the target interface identifier of the target slice information;

[0104] Step S404: Generate a chain establishment failure message;

[0105] Step S405: Generate first feedback information based on the target interface identifier and the connection failure message;

[0106] Step S406: Send the first feedback information to the base station so that the base station can configure slice information based on the target interface identifier in the first feedback information;

[0107] Steps S401-406 are the same as steps S301-306 in Example 2, and will not be described again in this example.

[0108] Step S407: Receive the second link establishment request information sent by the base station, wherein the second link establishment request information is generated by the base station based on the received target interface identifier;

[0109] After configuring the slice information based on the received target interface identifier, the base station continues to generate a second link establishment request, which contains the target interface identifier.

[0110] Specifically, the second chain establishment request information is the NGSETUP REQUEST information.

[0111] The second connection request information generated by the base station is identical to the first connection request information except for the request interface identifier.

[0112] The AMF receives a second link establishment request from the base station, which carries the interface identifier of the core network slice supported by the AMF.

[0113] Step S408: Analyze the second connection request information to obtain the target interface identifier;

[0114] The AMF analyzes the received second connection request information to obtain the target interface identifier carried in it.

[0115] The target interface identifier is the interface identifier with the slice in the core network supported by the AMF.

[0116] Step S409: Establish a connection with the base station based on the target interface identifier.

[0117] Since the second chain-building request information carries a target interface identifier, and the target interface identifier meets the agreed chain-building conditions, subsequent chain-building operations can be performed based on the target interface identifier in the second chain-building request information.

[0118] In summary, the base station network slicing configuration method provided in this embodiment further includes: receiving a second link establishment request information sent by a base station, wherein the second link establishment request information is generated by the base station based on a received target interface identifier; analyzing the second link establishment request information to obtain the target interface identifier; and establishing a link with the base station based on the target interface identifier. In this scheme, after receiving the second link establishment request generated by the base station based on the target interface identifier, a link is established with the base station based on the target interface identifier. Since the target interface identifier is provided to the base station by the AMF, the base station's configuration based on the target interface identifier ensures the accuracy of the configuration, and establishing a link based on the target interface identifier ensures successful link establishment.

[0119] like Figure 5 The flowchart shown is a fourth embodiment of a base station network slicing configuration method provided in this application. The method includes the following steps:

[0120] Step S501: Receive the first link establishment request information sent by the base station;

[0121] Step S502: Analyze the first link establishment request information to obtain the request interface identifier of the request slice information;

[0122] Step S503: Based on the fact that the requested interface identifier meets the acquisition conditions, obtain the target interface identifier of the target slice information;

[0123] Step S504: Generate a chain establishment failure message;

[0124] Step S505: Generate first feedback information based on the target interface identifier and the connection establishment failure message;

[0125] Step S506: Send the first feedback information to the base station so that the base station can configure slice information based on the target interface identifier in the first feedback information;

[0126] Step S507: Receive the second link establishment request information sent by the base station, wherein the second link establishment request information is generated by the base station based on the received target interface identifier;

[0127] Step S508: Analyze the second connection request information to obtain the target interface identifier;

[0128] Steps S501-508 are the same as steps S401-408 in Example 3, and will not be described again in this example.

[0129] Step S509: Based on the matching of the target interface identifier with the target interface identifier stored locally, determine that the target slice information carried in the second chain establishment request meets the agreed chain establishment conditions;

[0130] Among them, the interface identifier of the supported core network slice is stored locally in the AMF, which is the target interface identifier.

[0131] If the target interface identifier in the second link request is consistent with the target interface identifier stored locally in the AMF, and the interface identifier of the target slice information satisfies the communication protocol, then it can be determined that the target slice information carried in the second link request meets the agreed link establishment conditions.

[0132] Step S510: Generate a link establishment success message and send it to the base station.

[0133] The AMF generates a successful link establishment message and sends it to the base station, thus enabling the base station to establish a link with the target slice in the core network.

[0134] In summary, the method for configuring a base station network slice provided in this embodiment includes: determining that the target slice information carried in the second link establishment request information meets the agreed link establishment conditions based on the matching of the target interface identifier with the target interface identifier stored locally; and generating a link establishment success message and sending it to the base station. In this scheme, the AMF determines that the target interface identifier in the second link establishment request information received from the base station matches the target interface identifier stored locally, determines that the target slice information carried in the second link establishment request information meets the agreed link establishment conditions, generates a link establishment success message and sends it to the base station, thereby realizing the process of establishing a link between the base station and the core network.

[0135] like Figure 6 The flowchart shown is a fifth embodiment of a method for configuring a base station network slice according to this application. The method includes the following steps:

[0136] Step S601: Receive the first link establishment request information sent by the base station;

[0137] Step S602: Analyze the first link establishment request information to obtain the request interface identifier of the request slice information;

[0138] Step S603: Based on the fact that the requested interface identifier meets the acquisition conditions, obtain the target interface identifier of the target slice information;

[0139] Step S604: Generate a chain establishment failure message;

[0140] Step S605: Generate first feedback information based on the target interface identifier and the connection establishment failure message;

[0141] Step S606: Send the first feedback information to the base station so that the base station can configure slice information based on the target interface identifier in the first feedback information;

[0142] Step S607: Receive the second link establishment request information sent by the base station, wherein the second link establishment request information is generated by the base station based on the received target interface identifier;

[0143] Step S608: Analyze the second connection request information to obtain the target interface identifier;

[0144] Step S609: Establish a connection with the base station based on the target interface identifier;

[0145] Steps S601-609 are the same as steps S401-409 in Example 3, and will not be described again in this example.

[0146] Step S610: Update the target slice information and target interface identifier based on the received configuration information;

[0147] In addition, after the base station establishes a link with the core network, the AMF can also update the configuration information of the established link.

[0148] Specifically, the target slice information and target interface identifier corresponding to the base station are updated.

[0149] In practice, updated slice information and interface identifiers can be input through an input structure (such as a keyboard and mouse, touch structure, etc.) connected to AMF; or updated slice information and interface identifiers can be obtained from storage space based on an agreed automatic update cycle / time. This application does not restrict the source and acquisition method of such configuration information.

[0150] Step S611: Generate an update message based on the updated target interface identifier and send it to the base station so that the base station updates the slice information configuration based on the update message.

[0151] This involves generating an update message, which carries the updated target interface identifier.

[0152] Specifically, the update message is CONFIGURATIONUPDATE.

[0153] The update message is sent to the base station. After receiving the update message, the base station analyzes it to obtain the target interface identifier and updates the slice information configuration based on the updated target interface identifier, so that the slice information in the corresponding core network of the base station is consistent with that in the AMF.

[0154] In practice, after the baseline updates the slice information configuration based on the update message, it sends a configuration update feedback message to the AFM to notify the AFM that the information has been updated and recorded.

[0155] Specifically, the base station sends an AKC (ACKNOWLEDGE) message to the AMF.

[0156] In summary, the base station network slicing configuration method provided in this embodiment further includes: updating the target slice information and the target interface identifier based on the received configuration information; generating an update message based on the updated target interface identifier and sending it to the base station, so that the base station updates the slice information configuration based on the update message. In this scheme, the interface identifier of the base station can also be updated at the AMF (Application Function Manager). The AMF sends the updated target interface identifier to the base station in the form of an update message, so that the base station updates its slice information configuration based on the update message, ensuring that the slice information in the corresponding core network of the base station is consistent with that in the AMF, thus guaranteeing that the base station configuration is consistent with the AMF configuration.

[0157] like Figure 7The diagram shown is a flowchart of Embodiment 6 of a method for configuring a base station network slice according to this application. The method is applied to a base station and includes the following steps:

[0158] Step S701: Generate first chain establishment request information, wherein the request interface identifier for requesting slice information in the first chain establishment request information satisfies the acquisition condition;

[0159] If a base station requests to establish a link for the first time, it sends a first link establishment request to the management network element AMF. This first link establishment request carries the request interface identifier corresponding to the slice information requested by the base station.

[0160] Specifically, the connection establishment request information sent by the base station to the AMF also carries other information, such as location information, the base station's own IP address, port number, etc.

[0161] It should be noted that the request interface identifier in the connection establishment request information sent by the base station when it first requests connection establishment is empty, in order to ensure that the management network element sends back the target interface identifier it stores to the base station. In specific implementation, when the base station fails or its configuration information is incorrect or lost for other reasons, the base station can also act as the first to request connection establishment and generate the first connection establishment request information.

[0162] Step S702: Send the first connection establishment request information to the management network element, so that the management network element can feed back the target interface identifier to the base station based on the request interface identifier meeting the acquisition conditions;

[0163] The base station sends the generated first connection establishment request information to the AMF. After receiving the first connection establishment request information, the AMF analyzes it to obtain the request interface identifier.

[0164] If the request interface identifier is empty, the AMF cannot establish a link for the base station based on the empty request interface identifier. That is, the request interface identifier carried in the first link establishment request information does not meet the agreed link establishment conditions. However, it can trigger the operation of obtaining the interface identifier from the AMF locally. That is, the empty request interface identifier meets the acquisition conditions.

[0165] Specifically, based on the request interface identifier carried in the first connection establishment request information, the AMF is triggered to obtain the target interface identifier from the local machine. The target interface identifier is the interface identifier corresponding to the core network slice supported by the AMF, and then the target interface identifier is fed back to the base station.

[0166] In practice, the AMF packages the connection failure message with the target interface identifier and sends it to the base station.

[0167] Specifically, the chain establishment failure message includes information such as the reason for the failure.

[0168] Step S703: Receive the target interface identifier of the target slice information fed back by the management network element, wherein the target slice information is the slice information supported by the management network element;

[0169] The management network element sends the target interface identifier of the supported target slice information to the base station along with the link establishment failure message. After receiving the link establishment failure message, the base station obtains the target interface identifier from it.

[0170] In practice, the base station can first identify the link establishment failure message, and only after confirming the link establishment failure will it obtain the target interface identifier.

[0171] In practice, the base station can first identify a specific field in the link establishment failure message. The content carried in this field is the target interface identifier fed back to the base station by the AMF. If the specific field is not empty, the target interface identifier is obtained.

[0172] Step S704: Configure slice information based on the target interface identifier.

[0173] In this process, the base station configures slice information based on the target interface identifier received from the AMF. Since the AMF sends the target interface identifier corresponding to the target slice information it obtains to the base station, the slice information configured by the base station based on the target interface identifier must be a slice supported by the AMF.

[0174] The base station configures slice information based on the received target interface identifier, and subsequently establishes links with the corresponding target slice based on the configured slice information.

[0175] It should be noted that the first link establishment request information sent by the base station when it first requests link establishment carries an empty request interface identifier to trigger the AMF to provide the base station with the target interface identifier corresponding to its own target slice information, and feeds back the target interface identifier to the base station. The slice corresponding to the target interface identifier received by the base station is one that the base station can successfully establish a link with. Therefore, the base station can ensure that the network slice configuration can be successfully established by configuring based on the received target interface identifier.

[0176] In summary, this embodiment provides a method for configuring a base station network slice. The base station generates a first connection establishment request information where the requested interface identifier in the request slice information meets the acquisition conditions. The management network element, based on the fact that the requested interface identifier in the first connection establishment request information meets the acquisition conditions, obtains locally supported target slice information and its target interface identifier, and sends the target interface identifier to the base station. The base station then configures the slice information based on the target interface identifier. Since the target interface identifier received by the base station is automatically provided by the management network element and represents the interface identifier of the slice information supported by the management network element, compared to manual configuration which requires searching and manual input, the base station's configuration of slice information based on the target interface identifier provided by the management network element is more accurate and faster.

[0177] like Figure 8 The flowchart shown is a 7th embodiment of a base station network slicing configuration method provided in this application. The method includes the following steps:

[0178] Step S801: Generate first chain establishment request information, wherein the request interface identifier for requesting slice information in the first chain establishment request information satisfies the acquisition condition;

[0179] Step S802: Send the first connection establishment request information to the management network element, so that the management network element can feed back the target interface identifier to the base station based on the fact that the request interface identifier meets the acquisition conditions;

[0180] Step S803: Receive the target interface identifier of the target slice information fed back by the management network element, wherein the target slice information is the slice information supported by the management network element;

[0181] Step S804: Configure slice information based on the target interface identifier;

[0182] Steps S801-804 are the same as steps S701-704 in Example 6, and will not be described again in this example.

[0183] Step S805: Generate a second connection establishment request based on the configured target interface identifier;

[0184] After configuring the slice information based on the received target interface identifier, the base station continues to generate a second link establishment request, which contains the target interface identifier.

[0185] Specifically, the second chain establishment request information is the NGSETUP REQUEST information.

[0186] The second connection request information generated by the base station is identical to the first connection request information except for the request interface identifier.

[0187] Step S806: Send the second connection establishment request information to the management network element so that the management network element can verify the target interface identifier of the second connection establishment request information;

[0188] After generating the second link establishment request information, the base station sends it to the management network element.

[0189] In this process, the AMF receives the second link establishment request information sent by the base station, obtains the interface identifier of the core network slice supported by the AMF carried therein, and verifies the target interface identifier in the second link establishment request information to determine whether it meets the agreed link establishment conditions.

[0190] The target interface identifier is the interface identifier of the slice in the core network supported by the AMF. Since the second chain establishment request information carries the target interface identifier, and the target interface identifier meets the agreed chain establishment conditions, subsequent chain establishment operations can be performed based on the target interface identifier in the second chain establishment request information.

[0191] Step S807: Receive a link establishment success message sent by the management network element. The link establishment success message is output by the management network element based on the determination that the target slice information carried in the second link establishment request meets the agreed link establishment conditions.

[0192] In this process, once the AMF determines that the target interface identifier meets the agreed link establishment conditions, it sends a link establishment success message to the base station, thus enabling the target slice in the core network to successfully establish a link with the base station.

[0193] In summary, the method for configuring a base station network slice provided in this embodiment further includes: generating second link establishment request information based on the configured target interface identifier; sending the second link establishment request information to a management network element, so that the management network element verifies the target interface identifier of the second link establishment request information; and receiving a link establishment success message sent by the management network element, wherein the link establishment success message is output by the management network element based on determining that the target slice information carried in the second link establishment request information meets the agreed link establishment conditions. In this scheme, the second link establishment request information is generated based on the target interface identifier provided by the management network element and sent to the management network element, so that the management network element establishes a link with the base station based on the target interface identifier. Since the target interface identifier is provided to the base station by the AMF, the base station's configuration based on the target interface identifier ensures the accuracy of the configuration, and link establishment based on the target interface identifier ensures successful link establishment.

[0194] like Figure 9 The diagram shown is a sequence diagram of a method for configuring a base station network slice, in which the scenario includes the management network element (AMF) and the base station.

[0195] Step S901: The base station sends the first link establishment request information (NG SETUP REQUEST(1)) to the AMF;

[0196] The request interface identifier in the chain establishment request information is empty.

[0197] Step S902: AMF reports a connection establishment failure message (NG SETUP FAILURE);

[0198] The chain establishment failure message carries the target interface identifier of the core network target slice supported by AMF.

[0199] Step S903: The base station sends the link establishment request information again (NG SETUP REQUEST(2));

[0200] In this chain establishment request information, the request interface identifier is the target interface identifier.

[0201] Step S904: AMF sends a message indicating successful chain establishment (NG SETUP RESPONSE);

[0202] The target slice between the base station and the core network has been successfully linked. Subsequently, the target slice corresponding to the link established by the base station can be modified through AMF.

[0203] Step S905: The AMF sends configuration update information (AMF CONFIGURATUIN UPDATE) to the base station;

[0204] After receiving the update information, the base station updates its configuration based on the new target slice information (including the request interface identifier and other information) in the update information.

[0205] Step S906: The base station sends an update feedback message to the AMF (AMF CONFIGURATUIN UPDATEACKNOWLEDGE).

[0206] Corresponding to the above-described method embodiment for configuring a base station network slice, this application also provides an apparatus embodiment for applying the method for configuring a base station network slice.
