Description

Obtaining method, network element, device and storage medium of prediction information

technical field

The present application relates to the field of wireless communication technologies, and in particular, to a method, a network element, a device, and a storage medium for obtaining prediction information.

Background technique

In order to improve the operational efficiency and service quality of the 5th generation mobile networks (5G), the industry proposes that the prediction mechanism based on artificial intelligence (AI) can be applied to the 5G system, so that the latter can be Predict efficiently and flexibly allocate resources.

In order to achieve this purpose, prediction for user equipment (UE, User Equipment) is generally regarded as a key technology, especially UE trajectory prediction and service prediction. In the core network of the 5G system, each network element uses 5G-S-TMSI (5G S-Temporary Mobile Subscription Identifier, 5GS Temporary Mobile Subscription Identifier) and other identifiers to mark a UE, and the 5G-S-TMSI changes cycle It is very long and can basically be regarded as a static UE identity in actual use. When a network element without prediction function needs to optimally generate context (that is, optimally generate configuration) based on the prediction for a certain UE, it can send an interface message to the network element with prediction function and pass The message contains the UE's 5G-S-TMSI to indicate which UE's prediction information is requested.

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

This brings the following problems: an important purpose of the prediction information for a certain UE is to optimize the configuration for the UE. However, according to the prior art, there is a common situation as follows: the generator of the configuration is requested to generate Before the configuration of the UE, any interface signaling connection for the UE has not been established between it and the network element with the prediction function, so that the generator of the configuration cannot obtain the prediction information for the UE, and thus cannot optimize the UE according to the prediction information.

Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

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 the UE to optimize the UE configuration before being requested to generate the configuration for a certain UE. This enables the configuration generator in the radio access network to optimize the generation of the context for the UE according to the prediction information when the context for a certain UE has not been held before, while ensuring user privacy. To facilitate a clearer understanding of the embodiments of the present application, some related technical knowledge is first introduced as follows.

1. Use prediction to optimize the configuration for the UE

In a traditional wireless communication system, the configuration of the network for the UE is often only generated based on current information or historical information. For example, the network usually configures measurement for the UE, instructing the UE to start measuring the signal of the neighboring cell when certain conditions are met. If the signal strength of the neighboring cell and the local cell satisfies a certain relationship (the specific relationship that needs to be satisfied is also configured by the network) , the UE will report the measurement result, and inform the network of the signal strength of the neighboring cell and the signal strength of the current cell. The network then compares the two signal strengths with a preset threshold, and if the conditions are met, triggers the handover process. In addition, when the network configures services for the UE, it only considers static information such as QoS (Quality of Service, quality of service) information about these services provided by the core network.

However, with the development of AI technology, the industry proposes that AI technology can be applied to 5G networks to predict the future location and service requirements of UEs, and then optimize the configuration based on these predictions.

For example, before the handover, the network can select the cell with the longest expected service duration and the highest expected average signal quality as the handover when multiple cells can provide services for the UE according to the predicted future motion trajectory of the UE. In order to minimize the impact of the handover process on the service, improve the service experience of the UE, and reduce the signaling load caused by the handover to the network.

For another example, if the network predicts that the services of the UE in the future will focus on low-traffic and delay-sensitive services (such as real-time voice), then the network can pay more attention to the signal coverage in the handover judgment to ensure the service continuity of the UE. Less consideration is given to the capacity and load of the candidate target cells, so it tends to select low-frequency and wide-coverage cells. Conversely, if the network predicts that the UE's services in the future will focus on high-traffic services (such as non-real-time video downloads), then the network can pay more attention to the capacity and load of the candidate target cell during handover judgment to ensure the data transmission rate. Less consideration is given to signal coverage, so high-frequency broadband cells tend to be selected.

In order to take into account the accuracy of the prediction for a certain UE (for which it is necessary to collect as much data about the UE as possible) and the user's privacy requirements, the industry proposes that the AI-based prediction module can be deployed separately and centrally (generally should be located in the computer room). inside) to reduce security risks. The AI prediction module is called DCA (Data Collection and Analysis) module. In order to ensure the real-time performance of data collection as much as possible, reduce the signaling load as much as possible, and minimize the impact on the existing RAN (Radio Access Network, radio access network), the industry proposes that the DCA module can be used with any existing RAN. Node communication, its communication interface is a dedicated interface for AI functions designed separately. In principle, the DCA module can use this interface to obtain the information it needs from other nodes in the RAN as prediction inputs, and other nodes in the RAN can also use this interface to obtain prediction information from the DCA module.

2. UE identity in 5G access network

The 5G radio access network, or NG-RAN, consists of various network elements. When a UE accesses the network, the network selects some network elements in the NG-RAN to serve the UE. For this purpose, 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 valid UE identity, but only store the temporary identity as an index of the UE context.

Specifically, for a network element in the NG-RAN, it may be referred to as "network element A" here. In the case that it is establishing or has established a context related to the UE, if the network element needs to receive another network element The UE-related signaling sent by the element (here may be referred to as "network element B"), it will assign a "UE interface AP (ApplicationProtocol, application protocol) ID (Identity, identification)" to the UE and its context As an index, it is notified to network element B through interface signaling. After that, whenever the network element B needs to send an interface message related to the UE to the network element A, the network element B should include the above-mentioned "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 by using the "UE interface AP ID" contained in the message. Even for the same UE, when different network elements allocate "UE interface AP ID", the operations are independent of each other, and the assigned "UE interface AP ID" is completely irrelevant in value, making any potential attacks Even if the attacker hacks into two network elements, as long as there is no direct connection related to the UE between the two network elements, it cannot judge that they are targeting the same UE through the UE context stored in the two network elements. One UE, which significantly increases the difficulty for attackers to track the UE by hacking into a small number of base stations.

3. UE-related context establishment process

Due to the movement of the UE itself or the change of the service situation, the network sometimes needs to dynamically adjust the network element that serves the UE, so that a network element that did not serve the UE originally generates a context related to the UE, and generates some contexts related to the UE. necessary configuration. The most typical scenario is the handover process: due to the movement of the UE itself, the NG-RAN node that originally served it (each NG-RAN node has a complete base station function and can be composed of multiple network elements) can no longer After providing services for it, the NG-RAN node will request another NG-RAN node to provide services for it by triggering the handover process, including establishing a corresponding context related to the UE, and generating a post-handover configuration.

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:

1) Handover flow based on NG interface. The NG interface refers to the signaling interface between the NG-RAN node and the core network. In this type of handover procedure, the UE is initially served by the source NG-RAN node of the handover, and the source node decides to serve the UE by the target NG-RAN node for some reason, then the source NG-RAN node will first use the The core network initiates a request to the target NG-RAN node to request the target NG-RAN node to generate the context of the UE, generate 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 (Source to Target Container)", specifically the Source NG-RAN to Target NG-RAN Container (Source NG-RAN to Target NG-RANContainer), which contains the necessary and Access stratum (Access Spectrum, AS) context information related to the UE is used for configuration by the target NG-RAN node. The source NG-RAN node will include the container in the Handover Required message it sends to the core network, and after the core network receives this message, it will include the container in its destination. In the handover request (Handover Request) message sent by the target NG-RAN node. That is to say, the "source-to-target container" can be understood as a kind of information sent by the handover source NG-RAN node to the handover target NG-RAN node.

2) Handover flow based on Xn interface. The Xn interface refers to the signaling interface between two NG-RAN nodes. In this type of handover procedure, the UE is initially served by the handover source NG-RAN node, and the source node decides to serve the UE by the target NG-RAN node for some reason, then the source NG-RAN node will pass Xn The interface sends a handover request (Handover Request) message to the target NG-RAN node to request the target NG-RAN node to generate the context of the UE and generate corresponding configuration information. This handover request message will contain necessary access stratum context information related to the UE.

3) Extract UE context flow. For some reason, the connection between one UE and the NG-RAN node serving the UE is broken, and then the UE establishes a connection with another NG-RAN node in the vicinity. 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 may send an extract UE context request to the former NG-RAN node ( Retrieve UE Context Request) message. After the previous NG-RAN node passes the verification, it will feed back 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 the corresponding UE context. configuration information. This extract UE context response message will contain necessary access stratum context information related to the UE.

4) Auxiliary node adding process. In a 5G system, one 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 serve the UE for some reason (such as insufficient bandwidth), it will send a message to the latter NG-RAN node via the Xn interface A secondary node addition request (S-NodeAddition Request) message, requesting the latter to act as the secondary node (Secondary Node) of the UE, including 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 includes necessary access stratum context information related to the UE.

5) UE context establishment process. In the 5G system, an NG-RAN node can be subdivided into two parts: CU (Central Unit, centralized unit) and DU (Distributed Unit, distributed unit). Specifically, one NG-RAN node may consist of one CU and one or more DUs. The CU and DU are connected by F1 interface or W1 interface. The CU controls and applies the high-level configuration, while the DU controls and applies the low-level configuration. 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 serve a certain UE, it will send a UE Context Setup Request message to an appropriate DU to request the DU to generate the UE's underlying context and generate the corresponding configuration information. This UE context establishment request message will contain necessary access stratum context information related to the UE.

6) Bearer context establishment process. The CU can be further subdivided into two parts: CU-CP (Control Plane, control plane) and CU-UP (User Plane, user plane). Specifically, one CU may consist of one CU-CP and one or more CU-UPs. The CU-CP and CU-UP are connected by E1 interface. CU-CP is responsible for configuration control, while CU-UP is responsible for user plane configuration application and dynamic scheduling. In order for a UE to obtain complete services, the CU-CP and CU-UP need to jointly provide services for the UE. To this end, when a CU-CP decides to serve a certain UE, it sends a Bearer Context Setup Request message to an appropriate CU-UP to request the CU-UP to generate the UE's User plane context. This bearer context establishment request message will contain necessary access stratum context information related to the UE.

It should be pointed out that the above list is a container or message that exists in the existing 5G system and is intended to enable a radio access network element to establish a UE context. In fact, within other systems including 4G (the 4th generation mobile communication technology, fourth generation mobile communication technology), and when interacting between different systems, there are other The network element establishes the container or message of the UE context, and their functions are basically similar to the container and message in the 5G system listed above, and will not be repeated here.

FIG. 1 is a schematic flowchart of a method for obtaining prediction information provided by an embodiment of the present application. The method is applied to a first network element in a wireless access network. As shown in FIG. 1 , the method includes the following steps:

Step 100: Receive a first interface message sent by a second network element in the wireless access network, where the first interface message includes first information; wherein the first information is prediction information corresponding to the user equipment UE or used to obtain the information corresponding to the UE. index of prediction information;

Specifically, since the network elements in the radio access network do not hold any static UE identifiers, they only hold temporary identifiers that are locally valid for each pair of network interfaces involving the network elements of the radio access network, which are called “for this UE interface signaling connection", so when the network element in the radio access network needs to request the prediction information from the network element with the prediction function, it cannot indicate to the network element with the prediction function which prediction information it is requesting for the UE. , so that the network element in the radio access network cannot directly obtain the prediction information for the UE from the network element with the prediction function.

In order to enable the first network element in the wireless access network to obtain the prediction information for the UE(s), in this embodiment of the present application, the second network element in the wireless access network first sends a message to the first network element A first interface message, where the first interface message includes first information, where the first information is prediction information corresponding to the UE or an index that can be used to obtain the prediction information corresponding to the UE.

The above prediction information may be at least one type of prediction information for the UE, such as prediction information for the future location of the UE or prediction information for the future service traffic of the UE, and so on.

The above-mentioned first interface message may be various interface messages or containers, such as source to target container, handover request message, extract UE context response message, secondary node addition request message, UE context establishment request message or bearer context establishment request message, etc.

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

Specifically, if the first information is prediction information corresponding to the UE, after receiving the first interface message sent by the second network element, the first network element can directly obtain the prediction information corresponding to the UE from the first interface message. It should be noted that the prediction information held by the second network element may be obtained in advance from the network element that can provide the prediction information, for example, the second network element may communicate with the network element with the prediction function through the core network obtained from the network element with the prediction function after establishing the interface signaling connection for the UE, or the second network element may have obtained the prediction information corresponding to the UE from a network element in other radio access networks in advance. obtained from.

If the first information is an index used to obtain prediction information corresponding to the UE, after receiving the first interface message sent by the second network element, the first network element cannot directly obtain the information corresponding to the UE from the first interface message. For the prediction information, the prediction information corresponding to the UE needs to be further obtained by other methods according to 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.

In the method for obtaining prediction information provided by the embodiment of the present application, the first network element in the wireless access network can obtain the prediction information corresponding to the UE from the first interface message sent by the second network element in the wireless access network or use In order to obtain the index of the prediction information corresponding to the UE, the first network element can obtain the prediction information corresponding to the UE without holding any static UE identifier, thereby ensuring user privacy.

Optionally, the first network element may be a network element in the radio access network that needs to generate a UE context, the second network element may be a network element in the radio access network that holds the UE context, and the network element that needs to generate the UE context is in After the prediction information corresponding to the UE is obtained, the context of the UE can be optimally generated according to the prediction information.

FIG. 2 is a schematic flowchart of a method for obtaining prediction information provided by an embodiment of the present application. As shown in FIG. 2 , the method includes the following steps:

Step 200: The network element holding the UE context (that is, the UE context holder) sends an interface message or container to the network element that needs to generate the UE context (that is, the UE context generator), which directly contains the prediction information for the UE, This enables the network element that needs to generate the UE context to optimally generate the UE context according to the prediction information.

The above-mentioned interface message or container is used to enable the configuration generator (ie, the UE context generator) to establish a context for the UE, including but not limited to source-to-target container, handover request message, extract UE context response message, secondary node add request message, UE context establishment request message, bearer context establishment request message, and so on.

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 traffic of the UE, and the like. The prediction information may be acquired in advance by the network element holding the UE context from the network element capable of providing the prediction information.

Step 201: The network element that needs to generate the UE context optimally generates the UE context according to the content contained in the above-mentioned interface message or container and combined with the prediction information in the above-mentioned interface message or container.

The advantage of this embodiment is that the delay is the lowest, and the configuration generator can perform the configuration immediately after receiving the message, and is applicable to all scenarios.

Optionally, in the case where the first information is an index, obtaining prediction information corresponding to the UE based on the first information, including:

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;

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 used to obtain prediction information corresponding to the UE, the second network element may also send the first information to the first network element. A second interface message, 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. It can be understood that the second interface message The index included in is the same as the index included in the first interface message.

It should be noted that the prediction information held by the second network element may be obtained in advance from the network element that can provide the prediction information, for example, the second network element may communicate with the network element with the prediction function through the core network obtained from the network element with the prediction function after establishing the interface signaling connection for the UE, or the second network element may have obtained the prediction information corresponding to the UE from a network element in other radio access networks in advance. obtained from.

Optionally, the above-mentioned second interface message may be an interface message transmitted through an interface dedicated to the AI function.

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