Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method, network element, device and storage medium for obtaining prediction information. Background Art

[0002] In order to improve the operational efficiency and service quality of the fifth generation mobile communication systems (5G), the industry has proposed that a prediction mechanism based on artificial intelligence (AI) can be applied to the 5G system so that the latter can allocate resources efficiently and flexibly based on the prediction.

[0003] To achieve this goal, prediction of user equipment (UE) is generally considered a key technology, especially UE trajectory prediction and service prediction. In the core network of the 5G system, each network element uses identifiers such as 5G-S-TMSI (5G S-Temporary Mobile Subscription Identifier, 5GS temporary mobile user identity) to mark a UE. The 5G-S-TMSI change cycle is very long, and it can basically be regarded as a static UE identifier in actual use. When a network element that does not have a prediction function needs to optimize the generation of a context (that is, optimize the generation of a configuration) based on the prediction for a certain UE, it can send an interface message to a network element with a prediction function, and indicate which UE the prediction information is requested for by including the 5G-S-TMSI of the UE in the message.

[0004] However, this method is not applicable to the 5G access network NG-RAN (Next Generation-Radio Access Network). This is because the network elements in NG-RAN, such as communication base stations, are often not deployed in the computer room and are vulnerable to theft or intrusion by attackers. In order to protect user privacy, the 5G standard requires that the network elements in NG-RAN do not hold any static UE identifiers, but only hold temporary identifiers that are valid for each local area of ​​the network interface involving the NG-RAN network element, which is called "interface signaling connection for the UE".

[0005] This brings up the following problem: an important use of prediction information for a certain UE is to optimize the configuration for the UE. However, according to the prior art, the following situation commonly exists: before the configuration generator is requested to generate the configuration for the UE, it has not established any interface signaling connection for the UE with the network element with prediction function, making it impossible for the configuration generator to obtain the prediction information for the UE, and thus unable to realize the function of optimizing the UE configuration according to the prediction information.

[0059] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0060] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] The embodiments of the present application provide a solution to the problem that the configuration generator in the current 5G wireless access network cannot obtain the prediction information for a UE to optimize the UE configuration before being requested to generate the configuration for the UE, so that the configuration generator in the wireless access network can optimize the context for the UE according to the prediction information when it does not have the context for the UE before, and can also ensure user privacy. In order to facilitate a clearer understanding of the embodiments of the present application, some relevant technical knowledge is first introduced as follows.

[0063] 1. Using prediction to optimize UE configuration

[0064] In traditional wireless communication systems, the network configuration for UE is often generated only based on current information or historical information. For example, the network usually configures measurements for the UE, instructing the UE to start measuring the signals of adjacent cells when certain conditions are met. If the signal strength of the adjacent cell meets a certain relationship with the signal strength of the current cell (the specific relationship to be met is also configured by the network), the UE will report the measurement results to inform the network of the signal strength of the adjacent cell and the signal strength of the current cell. Then, the network will compare these two signal strengths with a preset threshold, and if the conditions are met, the switching process will be triggered. In addition, when the network configures the services for the UE, it will only consider static information such as the QoS (Quality of Service) information about these services provided by the core network.

[0065] However, with the development of AI technology, the industry has proposed that AI technology can be applied to 5G networks to predict the future location and service needs of UEs, and then optimize the configuration based on these predictions.

[0066] For example, before switching, the network can select the cell with the longest expected service time and the highest expected average signal quality as the target cell for switching based on the predicted future movement trajectory of the UE when multiple cells can provide services for the UE, so as to minimize the impact of the switching process on the service, improve the UE's service experience, and reduce the signaling load caused by the switching on the network.

[0067] For another example, if the network predicts that the UE's services in the future will be concentrated on low-traffic, delay-sensitive services (such as real-time voice), then the network can focus more on signal coverage to ensure UE's service continuity when making handover decisions, and consider less the capacity and load of candidate target cells, and thus tend to choose low-frequency and wide-coverage cells. Conversely, if the network predicts that the UE's services in the future will be concentrated on high-traffic services (such as non-real-time video downloads), then the network can focus more on the capacity and load of candidate target cells to ensure data transmission rate when making handover decisions, and consider less the signal coverage, and thus tend to choose high-frequency and wide-bandwidth cells.

[0068] In order to balance the accuracy of predictions for a certain UE (for which it is necessary to collect as much data as possible about the UE) and the privacy needs of users, the industry has proposed that AI-based prediction modules can be deployed separately and centrally (generally in the computer room) to reduce security risks. This AI prediction module is called the DCA (Data Collection and Analysis) module. In order to ensure the real-time nature of data collection, minimize the signaling load, and minimize the impact on the existing RAN (Radio Access Network), the industry has proposed that the DCA module can communicate with any node in the existing RAN, and its communication interface is a separately designed AI function-specific interface. In principle, the DCA module can use this interface to obtain the information it needs from other nodes in the RAN as input for prediction, and other nodes in the RAN can also use this interface to obtain prediction information from the DCA module.

[0069] 2. UE Identification in 5G Access Network

[0070] The 5G radio access network, or NG-RAN, consists of multiple network elements. When a UE accesses the network, the network will select some network elements in the NG-RAN to provide services to the UE. To do this, these network elements need to establish a context related to the UE and generate corresponding configurations. In order to protect the privacy of the UE, these network elements do not store any long-term UE identifiers, but only store temporary identifiers as indexes of the UE context.

[0071] Specifically, for a network element in NG-RAN, which may be referred to as "network element A" here, when it is establishing or has established a context related to the UE, if the network element needs to receive UE-related signaling sent by another network element (which may be referred to as "network element B" here), it will allocate a "UE interface AP (Application Protocol) ID (Identity)" as an index for the UE and its context, and inform network element B through interface signaling. After that, whenever network element B needs to send an interface message related to the UE to network element A, network element B should include the above "UE interface AP ID" in the interface message. In this way, when network element A receives the interface message sent by network element B, it can infer which UE the message is for through the "UE interface AP ID" contained in the message. Even if the target is the same UE, different network elements operate independently when allocating "UE interface AP ID", and the values ​​of the allocated "UE interface AP ID" are completely unrelated. As a result, even if any potential attacker breaks into two network elements, as long as there is no direct connection related to the UE between the two network elements, it is impossible for the attacker to determine that they are targeting the same UE through the UE context once stored in the two network elements, thereby significantly increasing the difficulty for the attacker to track the UE by breaking into a small number of base stations.

[0072] 3. UE-related context establishment process

[0073] Due to the mobility of the UE itself or changes in business conditions, the network sometimes needs to dynamically adjust the network element that provides services to the UE, so that a network element that originally did not provide services to the UE generates a context related to the UE and generates some necessary configurations. The most typical scenario is the handover process: due to the mobility of the UE itself, the NG-RAN node that originally provided services to it (each NG-RAN node has complete base station functions and can be composed of multiple network elements) can no longer provide services to it. In this case, the NG-RAN node will trigger a handover process to request another NG-RAN node to provide services to it, including establishing the corresponding context related to the UE and generating the configuration after the handover.

[0074] In the existing NG-RAN, when the UE is already connected to the network, the process for requesting a network element to generate a context related to the UE includes the following six categories:

[0075] 1) Handover process based on NG interface. NG interface refers to the signaling interface between the NG-RAN node and the core network. In this type of handover process, the UE is initially served by the source NG-RAN node of the handover. For some reason, the source node decides to let the target NG-RAN node serve the UE. Then the source NG-RAN node will first initiate a request to the target NG-RAN node via the core network to request the target NG-RAN node to generate the context of the UE, generate the corresponding configuration information, and configure the air interface connection between it and the UE. The source NG-RAN node will first generate a "Source to Target Container", specifically the Source NG-RAN to Target NG-RAN Container, which contains the necessary Access Spectrum (AS) context information related to the UE for the target NG-RAN node to configure. The source NG-RAN node will include the container in the Handover Required message it sends to the core network, and after receiving this message, the core network will include the container intact in the Handover Request message it sends to the target NG-RAN node. In other words, this "source to target container" can be understood as a kind of information sent by the source NG-RAN node of the handover to the target NG-RAN node of the handover.

[0076] 2) Handover process based on Xn interface. Xn interface refers to the signaling interface between two NG-RAN nodes. In this type of handover process, the UE is initially served by the source NG-RAN node of the handover. For some reason, the source node decides to let the target NG-RAN node serve the UE. Then the source NG-RAN node will send a handover request (Handover Request) message to the target NG-RAN node through the Xn interface to request the target NG-RAN node to generate the context of the UE and generate the corresponding configuration information. This handover request message will contain the necessary access layer context information related to the UE.

[0077] 3) UE context extraction process. For some reason, the connection between a UE and the NG-RAN node serving the UE is disconnected, and then the UE establishes a connection with another nearby NG-RAN node. If the latter NG-RAN node identifies which NG-RAN node the UE was previously connected to based on the information provided by the UE, the latter NG-RAN node can send a Retrieve UE Context Request message to the former NG-RAN node. After verification, the former NG-RAN node will feedback a Retrieve UE Context Response message to the latter NG-RAN node, so that the latter NG-RAN node can generate the context of the UE and generate corresponding configuration information. This Retrieve UE Context Response message will contain the necessary access layer context information related to the UE.

[0078] 4) Secondary node addition process. In the 5G system, a UE can be served by two NG-RAN nodes at the same time. When the NG-RAN node serving a UE needs another NG-RAN node to provide services to the UE at the same time for some reason (such as insufficient bandwidth), it will send a secondary node addition request (S-NodeAddition Request) message to the latter NG-RAN node via the Xn interface, requesting the latter to act as the secondary node (Secondary Node) of the UE, which includes requesting the target NG-RAN node to generate the context of the UE and generate corresponding configuration information. At the same time, the previous NG-RAN node becomes the master node (Master Node) of the UE. This secondary node addition request message contains the necessary access layer context information related to the UE.

[0079] 5) UE context establishment process. In the 5G system, an NG-RAN node can be divided into two parts: CU (Central Unit) and DU (Distributed Unit). Specifically, an NG-RAN node can be composed of a CU and one or more DUs. The CU and DU are connected by an F1 interface or a W1 interface. The CU controls and applies high-level configurations, while the DU controls and applies low-level configurations. In order for a UE to obtain complete services, the CU and DU need to jointly provide services for the UE. To this end, when a CU decides to provide services for a UE, it sends a UE Context Setup Request message to a suitable DU to request the DU to generate the underlying context of the UE and generate corresponding configuration information. This UE context establishment request message will contain the necessary access layer context information related to the UE.

[0080] 6) Bearer context establishment process. CU can be further divided into CU-CP (Control Plane) and CU-UP (User Plane). Specifically, a CU can be composed of a CU-CP and one or more CU-UPs. The CU-CP and CU-UP are connected by the E1 interface. CU-CP is responsible for configuration control, while CU-UP is responsible for the configuration application and dynamic scheduling of the user plane. In order for a UE to obtain complete services, CU-CP and CU-UP need to jointly provide services for the UE. To this end, when a CU-CP decides to provide services for a certain UE, it will send a Bearer Context Setup Request message to a suitable CU-UP to request the CU-UP to generate a user plane context for the UE. This bearer context establishment request message will contain the necessary access layer context information related to the UE.

[0081] It should be pointed out that the above are the existing containers or messages in the existing 5G system, which are designed to enable a wireless access network element to establish a UE context. In fact, in other systems including 4G (the 4th generation mobile communication technology), and when different systems interact, there are some other containers or messages that are designed to enable a wireless access network element to establish a UE context. Their functions are basically similar to the containers and messages in the 5G system listed above, and they will not be repeated here.

[0082] Figure 1A flow chart of a method for obtaining prediction information provided in an embodiment of the present application is provided, and the method is applied to a first network element in a wireless access network, such as Figure 1 As shown, the method comprises the following steps:

[0083] Step 100: Receive a first interface message sent by a second network element in a wireless access network, where the first interface message includes first information; wherein the first information is prediction information corresponding to a user equipment UE or an index for obtaining prediction information corresponding to the UE;

[0084] Specifically, since the network elements in the wireless access network do not hold any static UE identifiers, but only hold temporary identifiers that are valid locally for each pair of network interfaces involving the wireless access network network elements, called "interface signaling connection for the UE", when the network elements in the wireless access network need to request prediction information from the network elements with prediction functions, they cannot indicate to the network elements with prediction functions which UE the prediction information is requested for, resulting in the network elements in the wireless access network being unable to directly obtain the prediction information for the UE from the network elements with prediction functions.

[0085] In order to enable the first network element in the wireless access network to obtain prediction information for UE (one or more), in an embodiment of the present application, the second network element in the wireless access network first sends a first interface message to the first network element, and the first interface message includes first information, wherein the first information is the prediction information corresponding to the UE or can be used to obtain the index of the prediction information corresponding to the UE.

[0086] The above-mentioned prediction information may be at least one kind of prediction information for the UE, such as prediction information for the future location of the UE or prediction information for the future service flow of the UE, and so on.

[0087] The first interface message may be various interface messages or containers, such as a source-to-target container, a handover request message, an extract UE context response message, a secondary node add request message, a UE context establishment request message or a bearer context establishment request message, and the like.

[0088] Step 101: Obtain prediction information corresponding to the UE based on first information.

[0089] Specifically, if the first information is the prediction information corresponding to the UE, the first network element can directly obtain the prediction information corresponding to the UE from the first interface message after receiving the first interface message sent by the second network element. It should be noted that the prediction information held by the second network element can be obtained in advance from a network element that can provide prediction information. For example, the second network element can obtain it from a network element with prediction function after establishing an interface signaling connection for the UE between the core network and the network element with prediction function in advance, or the second network element can obtain it from a network element in other wireless access networks that have obtained the prediction information corresponding to the UE in advance.

[0090] If the first information is an index for obtaining prediction information corresponding to the UE, the first network element cannot directly obtain the prediction information corresponding to the UE from the first interface message after receiving the first interface message sent by the second network element. It is also necessary to further obtain the prediction information corresponding to the UE through other methods based on the obtained index. The specific method of obtaining the prediction information corresponding to the UE based on the index will be introduced in the subsequent content.

[0091] The method for obtaining prediction information provided in the embodiment of the present application enables a first network element in a wireless access network to obtain prediction information corresponding to a UE or an index for obtaining prediction information corresponding to a UE from a first interface message sent by a second network element in the wireless access network, thereby enabling the first network element to obtain prediction information corresponding to a UE without holding any static UE identifier, thereby ensuring user privacy.

[0092] Optionally, the first network element may be a network element in the wireless access network that needs to generate a UE context, and the second network element may be a network element in the wireless access network that holds the UE context. After the network element that needs to generate the UE context obtains the prediction information corresponding to the UE, it can optimize the generation of the UE context based on the prediction information.

[0093] Figure 2 A flowchart of a method for obtaining prediction information provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0094] Step 200: The network element holding the UE context (i.e., the UE context holder) sends an interface message or container to the network element that needs to generate the UE context (i.e., the UE context generator), which directly includes prediction information for the UE, so that the network element that needs to generate the UE context can optimize the generation of the UE context according to the prediction information.

[0095] The above-mentioned interface message or container is used to enable the configuration generator (i.e., the UE context generator) to establish a context for the UE, including but not limited to a source to target container, a switching request message, an extract UE context response message, a secondary node addition request message, a UE context establishment request message, a bearer context establishment request message, and the like.

[0096] The above prediction information is at least one kind of prediction information for the UE, including but not limited to prediction of the future location of the UE, prediction of the future service flow of the UE, etc. The prediction information may be obtained in advance by the network element holding the UE context from the network element that can provide the prediction information.

[0097] Step 201: A network element that needs to generate a UE context generates the UE context in an optimized manner according to the content included in the above interface message or container and in combination with the prediction information in the above interface message or container.

[0098] The advantage of this embodiment is that the latency is minimal, the configuration generator can perform configuration immediately after receiving the message, and it is applicable to all scenarios.

[0099] Optionally, when the first information is an index, acquiring prediction information corresponding to the UE based on the first information includes:

[0100] receiving a second interface message sent by a second network element, where the second interface message includes prediction information and an index corresponding to the UE;

[0101] Specifically, if the first information included in the first interface message sent by the second network element to the first network element is an index for obtaining the prediction information corresponding to the UE, then the second network element may also send a second interface message to the first network element, wherein the second interface message includes the prediction information and index corresponding to the UE, so that the first network element can obtain the prediction information corresponding to the UE from the second interface message. It can be understood that the index included in the second interface message is the same as the index included in the first interface message.

[0102] It should be noted that the prediction information held by the second network element may be obtained in advance from a network element that can provide prediction information. For example, the second network element may obtain the prediction information from the network element with prediction function after establishing an interface signaling connection for the UE between the core network and the network element with prediction function. The second network element may also obtain the prediction information from other network elements in other wireless access networks that have obtained the prediction information corresponding to the UE.

[0103] Optionally, the second interface message may be an interface message transmitted through an interface dedicated to the AI ​​function.

[0104] Based on the index, prediction information corresponding to the UE is obtained from the second interface message.

[0105] Specifically, after receiving the second interface message sent by the second network element, the first network element can obtain the prediction information corresponding to the UE from the second interface message based on the index obtained from the first interface message and the association relationship between the prediction information and the index included in the second interface message.

[0106] The method for obtaining prediction information provided in the embodiment of the present application enables a first network element in a wireless access network to obtain prediction information corresponding to a UE from a second interface message sent by a second network element in the wireless access network, thereby enabling the first network element to obtain prediction information corresponding to a UE without holding any static UE identifier, thereby ensuring user privacy.

[0107] Figure 3 A flowchart of a method for obtaining prediction information provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method comprises the following steps:

[0108] Step 300, the network element holding the UE context (i.e., the UE context holder) sends a first interface message or container to the network element that needs to generate the UE context (i.e., the UE context generator), wherein the first interface message or container includes an index of prediction information for the UE, so that the network element that needs to generate the UE context can optimize the generation of the UE context according to the prediction information.

[0109] The above-mentioned first interface message or container is used to enable the configuration generator (i.e., the UE context generator) to establish a context for the UE, including but not limited to a source to target container, a switching request message, an extract UE context response message, a secondary node addition request message, a UE context establishment request message, a bearer context establishment request message, and the like.

[0110] Step 301: The network element holding the UE context sends a second interface message (generally speaking, this message should be transmitted through an interface dedicated to the AI ​​function) to the network element that needs to generate the UE context, which includes prediction information for the UE and an index of the prediction information.

[0111] The above prediction information is at least one kind of prediction information for the UE, including but not limited to prediction of the future location of the UE, prediction of the future service flow of the UE, etc. The prediction information may be obtained in advance by the network element holding the UE context from the network element that can provide the prediction information.

[0112] Step 302: Since the network element that needs to generate the UE context may be configured for multiple UEs at the same time, it needs to first determine the prediction information transmission message (i.e., the second interface message) related to the UE according to the index of the configuration information in step 300, and then obtain the prediction information related to the UE, and then optimize the context of the UE based on the content contained in the message or container in step 300 and the prediction information.

[0113] The advantage of this embodiment is that the interface usage is clear, and the delay and Figure 2 The corresponding embodiments are not much different and are applicable to all scenarios.

[0114] Optionally, when the first information is an index, acquiring prediction information corresponding to the UE based on the first information includes:

[0115] Sending a prediction information request message to a third network element, where the prediction information request message includes an index;

[0116] Specifically, if the first information included in the first interface message sent by the second network element to the first network element is an index for obtaining the prediction information corresponding to the UE, then after receiving the first interface message, the first network element can send a prediction information request message to the third network element, wherein the prediction information request message includes the index obtained by the first network element from the first interface message, so that the third network element can determine the prediction information corresponding to the UE based on the index.

[0117] Optionally, the third network element may be a network element that includes the functions of data collection and prediction based on AI, that is, a network element with prediction function. It should be noted that, since the interface signaling connection for the UE could not be established between the third network element and the first network element before (before the first network element sends a prediction information request message to the third network element), the index included in the prediction information request message sent by the first network element to the third network element (that is, the index included in the first interface message) should be an index that can indicate to the third network element which UE the prediction information is requested for. For example, the index can be the UE interface application protocol identifier used by the second network element when establishing an interface signaling connection for the UE between the core network and the third network element in advance. In this way, the third network element can know which UE the prediction information is requested for by the first network element based on the index included in the prediction information request message.

[0118] Optionally, the above prediction information request message can be transmitted through an interface dedicated to the AI ​​function.

[0119] A prediction information transmission message sent by a third network element is received, where the prediction information transmission message includes prediction information corresponding to the UE; wherein the prediction information corresponding to the UE is determined by the third network element based on an index.

[0120] Specifically, after the first network element sends a prediction information request message to the third network element, the third network element can determine the prediction information corresponding to the UE according to the index included in the received prediction information request message, and send a prediction information transmission message to the first network element, wherein the prediction information transmission message includes the prediction information corresponding to the UE, so that the first network element can obtain the prediction information corresponding to the UE from the prediction information transmission message. Optionally, the prediction information transmission message can also include the index obtained by the third network element from the prediction information request message.

[0121] Optionally, the above-mentioned prediction information transmission message can be transmitted through an interface dedicated to the AI ​​function.

[0122] According to the method for obtaining prediction information provided in the embodiment of the present application, the first network element in the wireless access network can request prediction information from the third network element according to the index sent by the second network element, so that the first network element can obtain the prediction information corresponding to the UE without holding any static UE identifier, thereby ensuring user privacy.

[0123] Figure 4 A flowchart of a method for obtaining prediction information provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method comprises the following steps:

[0124] Step 400: The network element holding the UE context (i.e., the UE context holder) sends an interface message or container to the network element that needs to generate the UE context (i.e., the UE context generator), which includes an index of the prediction information for the UE, so that the network element that needs to generate the UE context can optimize the generation of the UE context according to the prediction information.

[0125] The above-mentioned interface message or container is used to enable the configuration generator (i.e., the UE context generator) to establish a context for the UE, including but not limited to a source to target container, a switching request message, an extract UE context response message, a secondary node addition request message, a UE context establishment request message, a bearer context establishment request message, and the like.

[0126] Step 401: The network element that needs to generate the UE context sends a prediction information request message to the network element that can provide prediction information (i.e., the prediction information provider, which should generally be a network element that includes data collection and AI-based prediction functions) to request the other party to provide prediction information. This prediction information request message contains the index of the above prediction information, which is the same as the index obtained by the network element that needs to generate the UE context from the above interface message or container, and is an index that can indicate to the network element that can provide the prediction information which UE the prediction information is requested for.

[0127] Step 402: The network element capable of providing prediction information determines the prediction information requested by the network element that executes the configuration (i.e., the network element that needs to generate the UE context) according to the index in the prediction information request message, and then feeds back a prediction information transmission message containing the requested prediction information to the network element that needs to generate the UE context.

[0128] The above-mentioned prediction information is at least one kind of prediction information for the UE, including but not limited to prediction information for the future location of the UE, prediction information for the future service flow of the UE, etc.

[0129] Optionally, the above-mentioned fed back prediction information transmission message may also include an index of the network element capable of providing prediction information obtained from the prediction information request message, which is used to indicate that the prediction information transmission message is associated with the prediction information request message received in step 401.

[0130] Step 403 : The network element that needs to generate the UE context generates the UE context in an optimized manner according to the content included in the message or container in step 400 and the prediction information in step 402 .

[0131] The advantage of this embodiment is that the network elements have clear division of labor and clear signaling purposes. The network elements that need to generate UE context can directly obtain the latest prediction information from the network elements that can provide prediction information, and are not restricted by the communication protocol version of the network elements that need to generate UE context.

[0132] Optionally, when the first information is an index, acquiring prediction information corresponding to the UE based on the first information includes:

[0133] Receive a prediction information transmission message sent by a third network element, the prediction information transmission message including prediction information and an index corresponding to the UE; wherein the prediction information corresponding to the UE is determined by the third network element based on the index included in the prediction information request message after receiving the prediction information request message sent by the second network element.

[0134] Specifically, if the first information included in the first interface message sent by the second network element to the first network element is an index for obtaining the prediction information corresponding to the UE, then the second network element may also send a prediction information request message to the third network element, wherein the prediction information request message includes an index for obtaining the prediction information corresponding to the UE, so that the third network element can determine the prediction information corresponding to the UE based on the index. It can be understood that the index included in the prediction information request message is the same as the index included in the first interface message.

[0135] Optionally, the third network element may be a network element including the functions of data collection and prediction based on AI, that is, a network element with a prediction function. The second network element may be a network element in a wireless access network that establishes an interface signaling connection for the UE in advance between the core network and the third network element. It can be understood that after the interface signaling connection for the UE is established between the second network element and the third network element, the interface message related to the UE sent by the second network element to the third network element will include a UE interface application protocol identifier for the UE, which can indicate to the third network element which UE the interface message is related to, so the index included in the above-mentioned prediction information request message can be the UE interface application protocol identifier used when the second network element establishes an interface signaling connection for the UE between the core network and the third network element in advance, or it can be any other index identifier, for example, it can be the UE interface application protocol identifier used when the interface signaling connection for the UE is established between the first network element and the second network element.

[0136] After the second network element sends a prediction information request message to the third network element, the third network element can determine the prediction information corresponding to the UE based on the index included in the received prediction information request message, and send a prediction information transmission message to the first network element, wherein the prediction information transmission message includes the prediction information corresponding to the UE and the index obtained by the third network element from the prediction information request message, so that the first network element can obtain the prediction information corresponding to the UE from the prediction information transmission message.

[0137] Optionally, the above prediction information request message can be transmitted through an interface dedicated to the AI ​​function.

[0138] Optionally, the above-mentioned prediction information transmission message can be transmitted through an interface dedicated to the AI ​​function.

[0139] According to the method for obtaining prediction information provided in the embodiment of the present application, the second network element in the wireless access network can send a prediction information request message to the third network element, requesting the third network element to send prediction information to the first network element, so that the first network element can obtain the prediction information corresponding to the UE without holding any static UE identifier, thereby ensuring user privacy.

[0140] Figure 5 A flowchart of a method for obtaining prediction information provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the method comprises the following steps:

[0141] Step 500: The network element holding the UE context (i.e., the UE context holder) sends an interface message or container to the network element that needs to generate the UE context (i.e., the UE context generator), which includes an index of the prediction information for the UE, so that the network element that needs to generate the UE context can optimize the generation of the UE context according to the prediction information.

[0142] The above-mentioned interface message or container is used to enable the configuration generator (i.e., the UE context generator) to establish a context for the UE, including but not limited to a source to target container, a switching request message, an extract UE context response message, a secondary node addition request message, a UE context establishment request message, a bearer context establishment request message, and the like.

[0143] Step 501, the network element holding the UE context sends a prediction information request message to the network element that can provide prediction information (i.e., the prediction information provider, which generally should be a network element that includes data collection and AI-based prediction functions), requesting the other party to provide prediction information to the network element that needs to generate the UE context. This prediction information request message contains the index of the above prediction information, which is the same as the index obtained by the network element that needs to generate the UE context from the above interface message or container. In particular, the index can be the UE interface application protocol identifier in step 500. The network element that needs to generate the UE context can establish an interface signaling connection for the UE in advance between the core network and the network element that can provide prediction information.

[0144] Step 502: The network element capable of providing prediction information sends a prediction information transmission message to the network element that needs to generate a UE context, wherein the message includes prediction information and an index of the prediction information, which is obtained by the network element capable of providing prediction information from a prediction information request message.

[0145] The above-mentioned prediction information is at least one kind of prediction information for the UE, including but not limited to prediction information for the future location of the UE, prediction information for the future service flow of the UE, etc.

[0146] Step 503: Since the network element that needs to generate the UE context may be configured for multiple UEs at the same time, it needs to first determine the prediction information transmission message related to the UE according to the index of the configuration information in step 500, and then obtain the prediction information related to the UE, and then optimize the context of the UE based on the content contained in the message or container in step 500 and the prediction information.

[0147] The advantage of this embodiment is that the network elements have clear division of labor, and since the network element that needs to generate the UE context can directly obtain the latest prediction information from the network element that can provide prediction information, the delay is moderate.

[0148] Figure 6 A flow chart of a method for obtaining prediction information provided in an embodiment of the present application is provided, and the method is applied to a second network element in a wireless access network, such as Figure 6 As shown, the method comprises the following steps:

[0149] Step 600, start;

[0150] Step 601: Send a first interface message to a first network element in a wireless access network, where the first interface message includes first information so that the first network element can obtain prediction information corresponding to a user equipment UE based on the first information; wherein the first information is prediction information corresponding to the UE or an index for obtaining prediction information corresponding to the UE.

[0151] Specifically, since the network elements in the wireless access network do not hold any static UE identifiers, but only hold temporary identifiers that are valid locally for each pair of network interfaces involving the wireless access network network elements, called "interface signaling connection for the UE", when the network elements in the wireless access network need to request prediction information from the network elements with prediction functions, they cannot indicate to the network elements with prediction functions which UE the prediction information is requested for, resulting in the network elements in the wireless access network being unable to directly obtain the prediction information for the UE from the network elements with prediction functions.

[0152] In order to enable the first network element in the wireless access network to obtain prediction information for UE (one or more), in an embodiment of the present application, the second network element in the wireless access network first sends a first interface message to the first network element, and the first interface message includes first information, wherein the first information is the prediction information corresponding to the UE or can be used to obtain the index of the prediction information corresponding to the UE.

[0153] The above-mentioned prediction information may be at least one kind of prediction information for the UE, such as prediction information for the future location of the UE or prediction information for the future service flow of the UE, and so on.

[0154] The first interface message may be various interface messages or containers, such as a source-to-target container, a handover request message, an extract UE context response message, a secondary node add request message, a UE context establishment request message or a bearer context establishment request message, and the like.

[0155] If the first information is the prediction information corresponding to the UE, the first network element can directly obtain the prediction information corresponding to the UE from the first interface message after receiving the first interface message sent by the second network element. It should be noted that the prediction information held by the second network element can be obtained in advance from a network element that can provide prediction information. For example, the second network element can obtain it from a network element with prediction function after establishing an interface signaling connection for the UE between the core network and the network element with prediction function in advance, or the second network element can obtain it from a network element in other wireless access networks that have obtained the prediction information corresponding to the UE in advance.

[0156] If the first information is an index for obtaining the prediction information corresponding to the UE, then after receiving the first interface message sent by the second network element, the first network element cannot directly obtain the prediction information corresponding to the UE from the first interface message, but needs to further obtain the prediction information corresponding to the UE through other methods based on the obtained index.

[0157] The method for obtaining prediction information provided in the embodiment of the present application enables a first network element in a wireless access network to obtain prediction information corresponding to a UE or an index for obtaining prediction information corresponding to a UE from a first interface message sent by a second network element in the wireless access network, thereby enabling the first network element to obtain prediction information corresponding to a UE without holding any static UE identifier, thereby ensuring user privacy.

[0158] Optionally, when the first information is an index, the method further includes:

[0159] A second interface message is sent to the first network element, where the second interface message includes prediction information and an index corresponding to the UE, so that the first network element can obtain the prediction information corresponding to the UE from the second interface message based on the index.

[0160] Specifically, if the first information included in the first interface message sent by the second network element to the first network element is an index for obtaining the prediction information corresponding to the UE, then the second network element may also send a second interface message to the first network element, wherein the second interface message includes the prediction information and index corresponding to the UE, so that the first network element can obtain the prediction information corresponding to the UE from the second interface message. It can be understood that the index included in the second interface message is the same as the index included in the first interface message.

[0161] After receiving the second interface message sent by the second network element, the first network element can obtain the prediction information corresponding to the UE from the second interface message according to the index obtained from the first interface message and the association relationship between the prediction information and the index included in the second interface message.

[0162] It should be noted that the prediction information held by the second network element may be obtained in advance from a network element that can provide prediction information. For example, the second network element may obtain the prediction information from the network element with prediction function after establishing an interface signaling connection for the UE between the core network and the network element with prediction function. The second network element may also obtain the prediction information from other network elements in other wireless access networks that have obtained the prediction information corresponding to the UE.

[0163] Optionally, the second interface message may be an interface message transmitted through an interface dedicated to the AI ​​function.

[0164] The method for obtaining prediction information provided in the embodiment of the present application enables a first network element in a wireless access network to obtain prediction information corresponding to a UE from a second interface message sent by a second network element in the wireless access network, thereby enabling the first network element to obtain prediction information corresponding to a UE without holding any static UE identifier, thereby ensuring user privacy.

[0165] Optionally, when the first information is an index, the method further includes:

[0166] A prediction information request message is sent to a third network element so that the third network element can send a prediction information transmission message to the first network element, wherein the prediction information transmission message includes prediction information and an index corresponding to the UE; wherein the prediction information corresponding to the UE is determined by the third network element based on the index included in the prediction information request message.

[0167] Specifically, if the first information included in the first interface message sent by the second network element to the first network element is an index for obtaining the prediction information corresponding to the UE, then the second network element may also send a prediction information request message to the third network element, wherein the prediction information request message includes an index for obtaining the prediction information corresponding to the UE, so that the third network element can determine the prediction information corresponding to the UE based on the index. It can be understood that the index included in the prediction information request message is the same as the index included in the first interface message.

[0168] Optionally, the third network element may be a network element including the functions of data collection and prediction based on AI, that is, a network element with a prediction function. The second network element may be a network element in a wireless access network that establishes an interface signaling connection for the UE in advance between the core network and the third network element. It can be understood that after the interface signaling connection for the UE is established between the second network element and the third network element, the interface message related to the UE sent by the second network element to the third network element will include a UE interface application protocol identifier for the UE, which can indicate to the third network element which UE the interface message is related to, so the index included in the above-mentioned prediction information request message can be the UE interface application protocol identifier used when the second network element establishes an interface signaling connection for the UE between the core network and the third network element in advance, or it can be any other index identifier, for example, it can be the UE interface application protocol identifier used when the interface signaling connection for the UE is established between the first network element and the second network element.

[0169] After the second network element sends a prediction information request message to the third network element, the third network element can determine the prediction information corresponding to the UE based on the index included in the received prediction information request message, and send a prediction information transmission message to the first network element, wherein the prediction information transmission message includes the prediction information corresponding to the UE and the index obtained by the third network element from the prediction information request message, so that the first network element can obtain the prediction information corresponding to the UE from the prediction information transmission message.

[0176] A prediction information transmission message is sent to a first network element in a wireless access network, wherein the prediction information transmission message includes prediction information corresponding to a user equipment UE and an index for obtaining the prediction information corresponding to the UE, so that the first network element can obtain the prediction information corresponding to the UE based on the index included in a first interface message sent by a second network element in the wireless access network; wherein the prediction information corresponding to the UE is determined by the third network element based on the index included in the prediction information request message after receiving the prediction information request message sent by the second network element.

[0177] Specifically, since the network elements in the wireless access network do not hold any static UE identifiers, but only hold temporary identifiers that are valid locally for each pair of network interfaces involving the wireless access network network elements, called "interface signaling connection for the UE", when the network elements in the wireless access network need to request prediction information from the network elements with prediction functions, they cannot indicate to the network elements with prediction functions which UE the prediction information is requested for, resulting in the network elements in the wireless access network being unable to directly obtain the prediction information for the UE from the network elements with prediction functions.

[0183] The above-mentioned third network element may be a network element that includes the functions of data collection and prediction based on AI, that is, a network element with prediction function. It should be noted that, since the interface signaling connection for the UE could not be established between the third network element and the first network element before (before the first network element sends a prediction information request message to the third network element), the index included in the prediction information request message sent by the first network element to the third network element (that is, the index included in the first interface message) should be an index that can indicate to the third network element which UE the prediction information is requested for. For example, the index can be the UE interface application protocol identifier used when the second network element establishes an interface signaling connection for the UE between the core network and the third network element in advance. In this way, the third network element can know which UE the prediction information is requested for by the first network element based on the index included in the prediction information request message.
