[0021] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0022] RFSP (RAT Frequency Selection Priority Index) is a parameter index issued by the core network to the radio access network in a mobile communication network. Its core function is to allow the network to finely control the selection of the wireless network standard (such as 5G NR, 4G LTE) and frequency band for specific users, thereby achieving resource management, load balancing, and differentiated services. The network issues different RFSP indices to different users, allowing the base station to know which radio resource management policy to apply to that user. The RFSP itself is a numerical index (such as 1, 2, 3...), which does not represent a specific policy but points to a pre-configured "policy table" in the base station (such as gNB / eNB). After receiving this index, the base station "translates" it into a specific RRM (Radio Resource Management) policy. For example, index value 1 might map to "prioritize 5G network," while index value 2 might map to "prioritize a specific frequency band of the 4G network" to balance the load. RFSP is a parameter at the UE (User Equipment) level. Therefore, different users in the same cell can be assigned different RFSP indices and enjoy different network selection strategies.

[0023] The RFSP works as follows: Operators configure the mapping relationship between RFSP index values ​​and RRM policies in the base station according to their needs. When a UE registers with the network, the core network (AMF / MME) determines an RFSP index based on the user's subscription data (from the UDM), current network policies, and even requested network slices, and sends it to the base station via the N2 / S1 interface. After receiving the RFSP index, the base station queries its local mapping table and applies the corresponding RRM policy to the user, thereby affecting the user's idle-state cell reselection and connected-state handover behavior. For example, it may encourage specific users to camp on 5G cells in the idle state or guide connected-state users to switch to a specified frequency layer.

[0024] The Network Data Analytics Function (NWDAF) is a key network element in the 5G core network. Its core task is to collect massive amounts of raw data from all parts of the network, generate insightful analysis results through intelligent analysis, and feed these results back to other functional entities in the network so that they can make better decisions, thereby achieving network automation, intelligence, and efficiency.

[0025] The working principle of NWDAF is as follows: Consumer network elements (such as PCF policy control functions) subscribe to the types of analysis they are interested in from NWDAF; NWDAF collects relevant raw data from data sources (such as UPF, SMF) as needed, analyzes the data, and generates analysis reports; NWDAF notifies the subscribed network elements of the analysis results or directly responds to their requests; Consumer network elements (such as PCF) adjust network policies (such as modifying QoS parameters and adjusting handover thresholds) based on the received analysis results, thereby realizing intelligent network operation.

[0026] The AMF (Access and Mobility Management Function) is a core control plane network element in the 5G core network. It is responsible for handling the most critical management tasks when user equipment (UE) accesses the network, including registration, connection, mobility management, and security authentication. It is the essential path for all signaling interactions.

[0027] The core functions of the AMF include the following modules: Access and Registration Management: Handles user registration requests, executes network access control, and determines whether to allow the user to use the 5G network. During registration, it also retrieves the user's subscription data from the Unified Data Management (UDM). Mobility Management: Tracks the user's location (at different granularities such as the registration area and tracking area) and manages the user's mobility context when the user moves (e.g., switching from one base station to another, or moving across the AMF), ensuring the network can locate the user regardless of their location and guaranteeing service continuity. Connection Management: Maintains the signaling connection state between the UE and the network. It manages the UE's transitions between idle state (no data transmission, energy saving) and connected state (data transmission). For example, when a user has data to send, the AMF assists in quickly restoring the connection. Authentication and Security: During user registration, the AMF collaborates with the Unified Data Management (UDM) / Authentication Credentials Storage and Processing Function (ARPF) to authenticate the user's identity and negotiate and generate keys to protect subsequent signaling and user plane data, ensuring communication security. Network slice selection: When a user requests to use a specific network slice (such as a low-latency slice), the AMF will assist in selecting a suitable slice instance based on the user's subscription and request, and connect the user to the corresponding network function.

[0028] The User Plane Function (UPF) occupies a central position in the 5G core network for data flow forwarding, and its operation is highly dependent on the command of the control plane. Policy reception: All forwarding behaviors of the UPF are not autonomously determined, but strictly follow the instructions (such as packet inspection rules, forwarding action rules, QoS enforcement rules, etc.) issued by the Session Management Function (SMF) through the N4 interface.

[0029] The data flow forwarding path of UPF is as follows: Uplink: The base station sends the user's data packets to the UPF → The UPF processes the data packets according to the rules → and routes the data packets to the external data network (such as the Internet). Downlink: Data packets from the external network arrive at the UPF → The UPF, based on the session context and mobility anchor information → accurately forwards the data packets to the serving base station where the user is currently located.

[0030] When executing traffic statistics and policies, UPF periodically feeds back the execution status (such as traffic usage and link quality) to SMF so that SMF can dynamically adjust its policies. At the same time, UPF's performance data (such as throughput and latency) is also collected by NWDAF (Network Data Analysis Function) for network congestion prediction and intelligent analysis, thereby achieving more global intelligent scheduling.

[0031] In 5G networks, UE (User Equipment) refers to the terminal equipment directly used by the user, such as smartphones, tablets, laptops, IoT sensors, vehicle terminals, or CPE (Customer Premises Equipment). It is the starting and ending point of the entire mobile communication network service. The UE establishes a wireless connection with the 5G base station (gNB) through its radio frequency antenna and baseband chip. It is responsible for converting user application data (such as video and web pages) into wireless signals conforming to the 5G air interface standard for transmission, and receiving signals from the base station and parsing them back to retrieve data. When the UE powers on or enters a new area, it actively initiates a registration request to the network. During this process, the UE cooperates with the core network (such as AMF and AUSF) to complete identity authentication and authorization, proving itself as a legitimate user and obtaining network access rights. The UE needs to constantly track its network location and assist the network in completing handover when moving (such as moving from one cell's coverage area to another) to ensure uninterrupted service.

[0032] UDM (Unified Data Management) is a key data management network element in the 5G core network. It is responsible for storing and managing all user (UE) subscription data, authentication credentials and location information, and providing unified data query, update and subscription services for other core network elements (such as AMF and SMF).

[0033] UDM's core functionalities include the following management functions: Contract data management: Stores each user's online contract information, including: User identifier: such as SUPI (user permanent identifier).

[0034] Business authorization: Whether the user is allowed to use the 5G network, whether they are allowed to use specific network slices, and the QoS (Quality of Service) level they can enjoy, etc.

[0035] Service area restrictions: Whether users are allowed to roam or access specific areas.

[0036] Credential Management: UDM works in conjunction with AUSF (Authentication Server Function) to store users' long-term security keys and authentication methods. When a user registers, UDM provides the necessary authentication data to ensure the legitimacy of the user's identity.

[0037] User Location Management (UDM): The UDM records the current AMF (Access and Mobility Management Function) node to which a user is located, thus knowing which control node the user currently "belongs" to at the core network level. This helps the network quickly locate the correct AMF when it needs to page a user.

[0038] Provide unified data services: UDM, as the data source, provides query, subscription and notification services for contracted data to other network elements such as AMF, SMF, and NEF (Network Open Functions) through a standardized service interface (Nudm).

[0039] The wireless network (RAN) is the terminal network in a mobile communication system that directly faces the user terminal (UE), responsible for connecting user equipment to the core network via radio waves. In 5G networks, the RAN mainly consists of equipment such as base stations and antenna systems, and is commonly referred to as the RAN (Radio Access Network). Base Station (gNB): Responsible for establishing wireless connections with the UE, performing signal modulation and demodulation, resource scheduling, and management. Each base station covers a specific area, providing a stable network connection when the user moves within that area. Antenna System: The base station transmits and receives radio signals through antennas.

[0040] There are two main limitations in related technologies: Technical limitation 1: Existing technologies struggle to trigger complete differentiated services at the scene / location level in a commercial environment. For example, consider a venue package for commercial use: Expected process: ① When a user with a venue package arrives at a venue and performs the services covered by the package, ② The network identifies the user and the service and issues the terminal left-hand label display, end-to-end service guarantee strategy, network billing strategy, and post-evaluation SMS strategy according to the rules.

[0041] Existing solutions: Both existing technical solutions pose a risk of network performance degradation in commercial environments and cannot be deployed.

[0042] One approach is to trigger user location updates based on TAC (Tracking Area Code): 5G cells covering the venue area are configured with independent TACs. Once a user occupies a cell, a "mobility registration updating" registration request is triggered. The core network AMF obtains the policy from the PCF via N15 and triggers the end-to-end policy. Technical drawback: Configuring independent TACs for each scenario introduces the risk of TAC poaching in the wireless network.

[0043] Second, cell location updates based on subscribers: The cell-level location information of subscribers in the core network is reported to the network every time a user switches. Technical drawback: Reporting location information every time a user switches can generate a "signaling storm" risk due to a large amount of end-to-end signaling interaction.

[0044] In summary, the key challenge of technical limitation 1 lies in how the network can accurately configure end-to-end strategies at the venue level without causing performance degradation.

[0045] Technical limitation 2: Existing technologies cannot achieve coordination between differentiated service strategies of the wireless network and the core network. Taking the scheduling strategy of differentiated services as an example: First, the wireless network strategy: Several scheduling strategies based on "user + service" combinations are deployed on intelligent computing boards. When a smart computing board identifies a specific combination condition as active, it triggers the corresponding strategy, achieving differentiated scheduling at the user + service level. Second, the core network: User services are identified through NWDAF + intelligent UPF network elements. Based on the strategy, the 5QI of NON-GBR is changed to the 5QI of GBR to achieve user + service level scheduling.

[0046] The key challenge of technical limitation 2 is that the scheduling strategy of wireless network and core network can only be "relay triggering" of wireless network first and then core network or single core network, and cannot be "coordinated concurrent"; and the guarantee effect of core network relay triggering is uncertain when the wireless network strategy has been triggered.

[0047] In view of this, this application provides a method and related equipment for determining end-to-end communication strategies triggered by a base station. This solution proposes a signaling process that is identified and triggered by the base station to ensure end-to-end communication. Based on the current 3GPP framework and related technologies, it proposes a signaling process that triggers an N2 message to prompt the core network to start / stop the end-to-end strategy when a base station deploying a differentiated service package strategy identifies a specific user or a specific user + a specific service. This solves the problem that current technologies are unable to configure end-to-end strategies with precise scene / location granularity in commercial scenarios without incurring the performance degradation risks described in the background.

[0048] In the signaling flow proposed above, an end-to-end key identification parameter body is proposed: the parameter body includes user identifier, location identifier, radio-side policy effective identifier, radio-side policy information, core network policy effective identifier, core network policy information, etc.; to solve the problem that related technologies cannot achieve coordination between differentiated service policies of radio network and core network.

[0049] It should be noted that in all specific embodiments of this application, when processing data related to user identity or characteristics, such as user information, user behavior data, user historical data, and user location information, user permission or consent is obtained first. Furthermore, the collection, use, and processing of this data comply with relevant laws, regulations, and standards. In addition, when embodiments of this application require access to sensitive personal information of users, separate permission or consent from the user is obtained through pop-ups or redirection to confirmation pages. Only after obtaining the user's separate permission or consent is the necessary user-related data required for the proper functioning of these embodiments acquired.

[0050] See Figure 1 This application provides an end-to-end communication strategy determination system triggered by a base station. The system includes user equipment, a base station, and a core network, wherein the base station is communicatively connected to both the user equipment and the core network. The user equipment interacts with the core network via the base station for signaling.

[0051] It should be noted that, in the core network of this application embodiment, from the definition of the 3GPP protocol to the current core network, a solution has been implemented by deploying network elements such as NWDAF, intelligent UPF, and AM-PCF to achieve terminal differentiation display, scheduling assurance, and post-evaluation SMS. In the wireless network of this application embodiment, from the definition of the 3GPP protocol to the current wireless network, a solution has been implemented by deploying intelligent computing boards to achieve identification and assurance of services based on PLMN, 5QI, RFSP, traceid, and other protocols.

[0052] See Figure 2 This application provides an end-to-end communication strategy determination method triggered by a base station, applied to a base station, the method including steps S101 to S102.

[0053] Step S101: Obtain the trigger signal of the package user equipment in the base station / cell range, and send the policy update signal to the core network control plane network element according to the trigger signal. The parameter body of the policy update signal includes user information, location information and wireless network policy information. Step S102: Receive the policy update response signal fed back by the core network control plane network element, and determine the end-to-end communication policy based on the policy update response signal; the policy update response signal includes user information class and core network policy information class.

[0054] It should be noted that the aforementioned end-to-end communication strategy determination method triggered by the base station belongs to new signaling. This new signaling process is initiated by the 5G base station to interact with the core network via N2 messages. The present invention uses the name defined in the following embodiments, but the actual name may vary. Rights protection should be determined based on the triggering characteristics and function of the new signaling. The embedding method of this process in the relevant network process is related to the triggering scenario.

[0055] Referring to Table 1, the strategy update parameter body should at least contain the following message units and parameters. This invention temporarily defines them with the following names, but the actual names may vary. Rights protection should be determined based on the composition and function of the parameter body message units.

[0056] Table 1. Schematic diagram of strategy update parameter body

[0057] Referring to Table 2, the strategy update reply parameter body should at least contain the following message units and parameters. This invention temporarily defines them with the following names, but the actual names may vary. Rights protection should be identified based on the composition and function of the parameter body message units.

[0058] Table 2. Schematic diagram of strategy update reply parameter body

[0059] See Figure 3 In one specific embodiment, after the 5G base station (gNB) receives the trigger signal, it sends a strategy update signal to the core network control plane element (AMF); after receiving the strategy update signal, the core network control plane element (AMF) sends a strategy update reply signal back to the base station (gNB).

[0060] The signaling information exchange between the base station and the core network can be divided into at least the following three categories: 1. User Information Category: To identify users and then trigger end-to-end strategies based on user contract information.

[0061] 2. Location Information: Identify the user's device location / scene and then trigger network protection based on the user's contract information and the scene / venue policy.

[0062] 3. Policy Information: The base station reports the currently effective policy type to the core network. The core network determines its own policy based on the base station's policy, and the two sides interact to achieve end-to-end coordination.

[0063] It should be noted that the trigger signal is determined according to the actual application, and this embodiment does not impose any specific restrictions.

[0064] In some embodiments, see Figure 4 The trigger signal is obtained through the following method: Step S201: Obtain the access signal of the package user equipment entering the base station / cell range, and determine the identification information of the network frequency selection priority index of the package user equipment based on the access signal; Step S202: Identify user identity information based on the identification information of the priority index of the network frequency selection of the package user equipment, so as to obtain the trigger signal of the package user equipment.

[0065] See Figure 5 In one specific embodiment, a package user equipment (UE) enters the range of a 5G base station / cell. The package user equipment (UE) moves into the base station (gNB). The base station (gNB) can obtain the user's RFSP (Network Frequency Selection Priority Index) ID information through the Xn interface link of the previous base station or the UDM of the core network. Based on the RFSP ID, the user's identity information can be identified, triggering the new process in this embodiment of the invention to achieve policy coordination between the radio network and the core network.

[0066] In some embodiments, see Figure 6 Based on the trigger signal, a policy update signal is sent to the core network control plane network elements, including: Step S301: Determine the user identity parameter body and user location parameter body based on the user identity information, set the policy switching parameter body to the active state, and leave the wireless side policy type parameter body empty. Step S302: Determine the policy update signal based on the user identity parameter body, user location parameter body, policy switching parameter body, and radio-side policy type parameter body, and send the policy update signal to the core network control plane network element.

[0067] In one specific embodiment, a user device with a package enters the venue without using any package services. The base station that has deployed the package guarantee strategy identifies the user's identity through the RFSP ID information carried in the registration information (the principle is similar to 3GPP), triggers a "strategy update", and transmits the user's identity and location information. At this time, the strategy switch is set to the active state, indicating that the end-to-end strategy has been triggered. However, since no package services have been triggered at this time, there is no information in the "RAN strategy information".

[0068] The core network, by knowing that a user's device has entered the venue, triggers interaction regarding the user's package acceptance status and policy status, as well as NWDAF's processes for subscribing to and monitoring user data.

[0069] In some embodiments, see Figure 7 The methods also include: Step S401: Obtain the package services of the package user equipment entering the base station / cell range, and determine the service type of the package user equipment based on the package services; Step S402: If the service type is a preset protection type, obtain the trigger signal of the package user equipment.

[0070] In one specific embodiment, see Figure 8 When a user device within a package enters the 5G base station / cell range configured with the package policy and activates the package service, the base station can verify the user's identity information via the RFSP ID and identify the user's service type based on the assigned intelligent computing board. When the base station detects that the user's service type matches the type that the package requires to be protected, it triggers a new application process, achieving policy coordination with the core network.

[0071] In some embodiments, the method further includes: Update the radio-side policy type parameter body according to the service type so that the core network can update the policy update response signal.

[0072] In one specific embodiment, a user device with a package service enters the venue and uses the package service. After the base station identifies this through the intelligent computing board, it triggers a "strategy update," and the "RAN strategy information" displays the strategy, assuming that only the inter-frequency coordination strategy of the wireless network is implemented.

[0073] After obtaining the radio network policy, the core network further overlays scheduling policies and informs the radio network via "strategy updatereply". From the user's perspective, they simultaneously benefit from both the frequency division policy from the radio network and the scheduling policy from the core network.

[0074] In some embodiments, see Figure 9 The methods also include: Step S501: Obtain the identification information of the network frequency selection priority index of the user who has triggered the end-to-end communication policy; identify the user's identity information based on the identification information of the network frequency selection priority index of the user who has triggered the end-to-end communication policy; and obtain the trigger signal. Step S502: Determine the user identity parameter body and user location parameter body based on the user identity information, and set the policy switching parameter body to an inactive state; Step S503: Determine the policy update signal based on the user identity parameter body, user location parameter body, and policy switching parameter body, and send the policy update signal to the core network control plane network element so that the core network updates the policy update response signal.

[0075] In a specific embodiment, the wireless network applies, modifies, or deactivates a certain type of policy (e.g., mobility management, scheduling, power control, etc.) to package user equipment. When an end-to-end policy is triggered, the triggering status is transmitted between NG and XN during 5G handover. When a package user equipment leaves the package deployment area and enters a base station without a package policy, the base station without a package policy triggers a "strategy update" signal again, prompting the user to deactivate the end-to-end policy.

[0076] In one specific embodiment, a base station that has not deployed a package guarantee policy identifies the user's identity through the RFSPID information carried in the registration information, triggers a "strategy update", and transmits the user's identity and location information. At this time, the "strategyswitch" is set to an inactive state, which means that the end-to-end policy stops being triggered.

[0077] This application provides a method and related equipment for determining end-to-end communication policies triggered by a base station. The scheme acquires trigger signals from packaged user equipment within the base station / cell range, and sends policy update signals to the core network control plane elements based on these signals. The policy update signal's parameter body includes user information, location information, and radio network policy information. After identifying a specific packaged user equipment, it triggers the signaling process for the end-to-end policy, refining the granularity of the end-to-end communication policy triggering process to the base station / cell level without causing network performance degradation. It also receives policy update response signals from the core network control plane elements and determines the end-to-end communication policy based on these response signals. The policy update response signals include user information and core network policy information, enabling coordination between differentiated service policies of the radio network and the core network.

[0078] See Figure 10 This application also provides an end-to-end communication strategy determination device triggered by a base station, which can implement the above method. The device includes: The policy update module is used to obtain the trigger signal of the package user equipment in the base station / cell range, and send the policy update signal to the core network control plane network element according to the trigger signal. The parameter body of the policy update signal includes user information, location information and wireless network policy information. The strategy determination module is used to receive the strategy update response signal fed back by the core network control plane network element, and determine the end-to-end communication strategy based on the strategy update response signal; the strategy update response signal includes user information and core network strategy information.
