As described in the background art, wireless network management needs to be adapted to provide necessary data support for artificial intelligence and big data analysis. At present, the wireless network side also has the following problems that the point-to-point optimization of the UE cannot be satisfied:

1) In the existing wireless network management system, no management model is established for the UE, and for consideration of security factors, sensitive identifiers of the UE, such as an International Mobile Subscriber Identity (IMSI), a Temporary Mobile Subscriber Identity (TMSI), and a wireless network Temporary identifier (GRNTI) of a wireless side, are not exposed to the network management side, so that a specific UE cannot be located from the network management side.

2) In the aspect of existing wireless network management, a wireless network management side cannot obtain data information for a single UE, only can perform network adjustment with a coarser granularity by using a cell or a network element (base station) as a unit, and cannot perform optimization and adjustment of network service for a certain UE point to point.

In order to solve at least one of the above problems, embodiments of the present invention provide an identifier allocation method for a user equipment, which allocates a new identifier of a network management side to the user equipment, so as to ensure that a sensitive identifier of the user equipment is not exposed to the network management side, and provide support for implementing optimization and adjustment of a peer-to-peer network service at a user equipment granularity level.

Referring to fig. 1, a network topology architecture to which the embodiments of the present invention can be applied is provided. Organization a and organization B in fig. 1 each include a 3-layer managed network architecture defined by 3GPP, where the specific structure of organization B is similar to organization a and is not shown in detail in fig. 1. The numbers on the various connecting lines in fig. 1 (e.g., 1-7) or the combination of numbers and letters (e.g., 4a,5a, etc.) indicate the type of interface between the various units. Wherein NM denotes a Network Manager (Network Manager), EM denotes an Element Manager (Element Manager), and DM denotes a Domain Manager (Domain Manager). The identifier allocation method for the user equipment provided by the embodiment of the invention can be applied to the interface type 2 in fig. 1, namely, the traditional network management northbound interface.

Referring to fig. 2, a method for allocating identifiers of user equipment according to an embodiment of the present invention includes:

step 21, the first network element manager allocates a first network element manager part identifier for uniquely identifying the first user equipment to the first user equipment, and the first user equipment is a device in the first radio access network managed by the first network element manager.

Here, the first user equipment is a device in the first radio access network managed by the first network element manager, for example, the first user equipment may be a device residing under a certain cell of the first radio access network. In this embodiment of the present invention, a first network element manager allocates, to a first user equipment, a network element manager partial identifier (for convenience of description, referred to as a first network element manager partial identifier) that can uniquely identify the first user equipment.

Step 22, the first network element manager sends the identifier of the first network element manager part of the first user equipment to a first network manager, where the first network manager is a network manager to which the first network element manager belongs.

Here, the first network element manager is one managed by the first network manager. After the first network element manager allocates the first network element manager part identifier to the first user equipment, the first network element manager sends the first network element manager part identifier to the first network manager, so as to prompt the first network manager to continue allocating the network manager part identifier (for convenience of description, referred to as the first network manager part identifier) to the first user equipment.

Step 23, the first network element manager receives a first network manager side identifier of the first user equipment, which is sent by the first network manager, where the first network manager side identifier includes the first network element manager part identifier and a first network manager part identifier, which is allocated to the first user equipment by the first network manager and is used for uniquely identifying the first user equipment.

Here, after allocating a first network manager part identifier to a first user equipment, the first network manager may obtain a network management side identifier of the first user equipment (for convenience of description, referred to as a first network management side identifier), and send the network management side identifier to the first network element manager, where the first network management side identifier includes the first network element manager part identifier and the first network manager part identifier. And the first network element manager receives the first network management side identifier of the first user equipment, which is sent by the first network manager. In addition, the first network element manager may further establish a corresponding relationship between the first network element side identifier and a sensitive identifier (such as IMSI, TMSI, GRNTI, or the like) of the first user equipment. Here, the network element manager portion identifier and the "part" of the network manager portion identifier are for the network element side identifier and constitute part of the network element side identifier.

Through the above steps, the embodiment of the present invention may respectively maintain the first network manager side identifier of the first user equipment at the first network element manager and the first network manager side, so that the first user equipment may be uniquely identified by the first network manager side identifier, isolation of the user sensitive identifier is achieved, and support may be provided for achieving the optimization and adjustment of the point-to-point network service at the user equipment granularity level.

According to at least one embodiment of the present invention, the first network element manager may perform the operation in step 21 only when a certain user equipment needs to be managed, specifically, before step 21, the first network element manager may determine the user equipment that needs to be managed through a network manager, use the user equipment that needs to be managed as the first user equipment, and then enter step 21 to allocate the first network element manager part identifier to the first user equipment. When the first user equipment needing to be managed is determined, different implementation modes exist according to different application scenes.

For example, when user equipment in a certain target network element (specifically, the target network element may be a base station and/or a cell) needs to be managed, the process shown in fig. 2 may be triggered. At this time, the first network manager may determine the target network element and notify the network element manager to which the target network element belongs (i.e., the network element manager that manages the target network element, which is assumed to be the first network element manager); the first network element manager may receive the notification message of the target network element sent by the first network manager, and then use the user equipment within the coverage area of the target network element (e.g., the user equipment residing within the coverage area, or the user equipment having a connection with the target network element, etc.) as the first user equipment, so that the user equipment under a specific network element may be subsequently allocated with a network management side identifier through the flow shown in fig. 2, and further provide subsequent management of network services at a user equipment granularity level for the user equipment based on the network management side identifier.

For another example, the first network element manager receives a notification message of a target service sent by the first network manager; then, the first element manager uses the user equipment performing the target service in the network element managed by itself as the first user equipment, so that the user equipment performing the specific service can be subsequently allocated with a network management side identifier through the process shown in fig. 2, and further, based on the network management side identifier, the subsequent management of the network service at the granularity level of the user equipment is provided for the user equipment.

In consideration of factors such as mobility of the user equipment, the embodiment of the present invention may also perform, after the network management side identifier is allocated to the first user equipment, recovery of the network management side identifier according to a change in a location of the first user equipment, and specifically may include recovery of a network element manager part identifier and/or recovery of a network manager part identifier.

According to at least one embodiment of the present invention, after step 23, if the first ue moves out of the first radio access network managed by the first element manager, for example, the first ue drops or shuts down or removes the first radio access network through a process of cell reselection or cell handover, etc., at this time, the first element manager may recover the first element manager portion identifier of the first ue, and send a notification message for instructing to recover the first network manager portion identifier of the first ue to the first network manager.

According to at least one embodiment of the present invention, after step 23, if the first user equipment enters a second radio access network managed by a second network element manager from a first radio access network managed by the first network element manager, and a network manager to which the second network element manager belongs is also the first network manager, at this time, the first network element manager may recover the first network element manager partial identifier of the first user equipment. In addition, when the user equipment moves between the network element managers, the network manager part identifiers of the first user equipment can be interacted between the network element managers, so that the network manager does not need to allocate the network manager part identifiers for the first user equipment again. At this time, the first network element manager may send the first network manager part identifier of the first user equipment to the second network element manager, in addition to recovering the first network element manager part identifier of the first user equipment. For example, in the process of cell reselection or cell handover, etc., where the first user equipment enters the second radio access network from the first radio access network, the recovery and reallocation of the identifier of the network element manager portion may be performed according to the above procedure. Of course, when the user equipment moves between the network element managers, the network manager can re-allocate the network manager part identifier to the user equipment, and at this time, the operation of interacting the network manager part identifier of the user equipment between the network element managers is not needed.

In an actual scenario, in addition to that the user equipment with the above assigned network element side identifier may move out of the first radio access network managed by the first network element manager, it may also happen that the second user equipment enters the first radio access network from a radio access network (e.g. a second radio access network) managed by another network element manager (e.g. a second network element manager, assuming that the network manager to which the second network element manager belongs is also the first network manager), at this time, the first network element manager may assign a second network element manager portion identifier for uniquely identifying the second user equipment to the second user equipment, and send the second network element manager portion identifier of the second user equipment to the first network manager.

Similarly, in order to avoid reassigning the network manager part identifier, after the second user equipment moves into the first radio access network, the first network element manager may receive the second network manager part identifier of the second user equipment sent by the second network element manager; then, the first network element manager may allocate, to the second user equipment, a second network element manager part identifier for uniquely identifying the second user equipment, and send both the second network element manager part identifier and the second network manager part identifier of the second user equipment to the first network manager.

In addition, in the above process, how to detect the method for moving a certain ue out of or into a certain radio access network may refer to the flow of mobility management in the prior art, and for saving space, it is not described herein again.

The above describes the allocation and reclamation of the network manager side identity of the user equipment from the network element manager side. The above flow will be described next from the network manager side.

Referring to fig. 3, the method for allocating identifiers of a ue according to an embodiment of the present invention, when applied to a first network manager, includes:

step 31, a first network element manager receives a first network element manager part identifier of a first user equipment, which is sent by a first network element manager, where the first network element manager part identifier is an identifier that is allocated by the first network element manager for the first user equipment and is used for uniquely identifying the first user equipment, and the first network element manager is a network element manager managed by the first network manager.

Here, after the first network element manager allocates the first network element manager part identifier to the first user equipment, the first network element manager sends a notification message to the first network manager, where the notification message carries the first network element manager part identifier and is used to instruct the first network manager to continue allocating the network manager part identifier to the first user equipment. In step 31, the first network manager receives the identifier of the first element manager portion, and specifically may receive the notification message carrying the identifier of the first element manager portion.

Step 32, the first network manager allocates a first network manager part identifier for uniquely identifying the first user equipment to the first user equipment, and sends a first network manager side identifier of the first user equipment to the first network element manager, where the first network manager side identifier includes the first network element manager part identifier and the first network manager part identifier.

Here, the first network manager allocates a network manager part identifier (referred to as a first network manager part identifier for convenience of description) to the first user equipment, so as to generate a network management side identifier (referred to as a first network management side identifier for convenience of description) of the first user equipment based on the first network element manager part identifier and the first network manager part identifier, and return the first network management side identifier to the first network element manager.

Through the above steps, the embodiment of the present invention may respectively maintain the first network manager side identifier of the first user equipment on the first network manager side and the first network element manager side, so that the first user equipment may be uniquely identified by the first network manager side identifier, isolation of the user sensitive identifier is achieved, and support may be provided for the subsequent peer-to-peer network management of the user equipment granularity level.

According to at least one embodiment of the present invention, before step 31, the first network manager may determine a target network element (specifically, a base station or a cell) that needs to be managed and a network element manager to which the target network element belongs; then, the first network manager sends a notification message of a target network element to a network element manager to which the target network element belongs, where the network element manager to which the target network element belongs includes the first network element manager, and the first user equipment is user equipment in a coverage area of the target network element. Subsequently, through the flow shown in fig. 3, the network management side identifier may be allocated to the first user equipment in the target network element.

According to at least one embodiment of the present invention, before step 31, the first network manager may determine a target service that needs to be managed; then, a notification message of the target service is sent to the first network element manager. Here, the first user equipment is user equipment for performing a target service. Similarly, the flow shown in fig. 3 may be used to subsequently allocate a network management side identifier to the first user equipment performing the target service.

To implement the recycling process of the identifier, according to at least one embodiment of the present invention, after the step 32, the first network manager may further receive a notification message sent by the first network element manager and used for instructing to recycle the identifier of the first network manager portion of the first user equipment; then, the first network manager recovers the first network manager part identifier of the first user equipment according to the notification message.

In order to implement the identifier updating process, according to at least one embodiment of the present invention, after the step 32, the first network manager may further receive a second network manager part identifier and a second network manager part identifier of the second device, which are sent by the first network manager; then, judging whether the network element manager part identifier of the second device maintained by the first network manager is the same as the second network element manager part identifier, if so, not executing the processing, and ending the process; if not, the identifier of the element manager of the second device may be updated to the identifier of the element manager of the second device, so as to implement the update process of the user identifier.

The above introduces the user identifier allocation procedure from the network element manager and the network manager side. As can be seen from the above flow, the network management side identifier (denoted by UE _ Man _ ID) of the User Equipment (UE) in the embodiment of the present invention includes two parts, which are respectively: the network manager part identifier (represented by UE _ NM _ ID) and the network element manager part identifier (represented by UE _ EM _ ID) can adopt bits with a pre-agreed length, and then the bits of the two parts are connected together to form the UE _ Man _ ID. A unique identity under the network manager is typically assigned by the network manager for identifying the network manager part identity of the user equipment management plane, e.g. UE _ NM _ ID. Considering the mobility scenario of the UE across the element managers, in order for the network manager to be able to clearly identify the target element manager to which the subsequent configuration for the UE is sent, the network manager part identifier of the UE, such as UE _ EM _ ID, needs to be allocated.

I.e. the network management side identity of the user equipment UE _ Man _ ID = UE _ NM _ ID + UE _ EM _ ID.

In the embodiment of the invention, the network management side identifier of the user equipment is distributed by the network element manager and the network manager, and the network management side identifier is usually only effective in the network element manager and the network manager. Since different network managers may have different management policies and coverage areas, when the user equipment enters another network manager or element manager, the management of the other network manager or element manager will be obeyed.

For example, when the user equipment enters the equipment coverage area managed by another network element manager, the network element manager part identifier in the network management side identifier of the user equipment needs to be updated.

For another example, after the ue enters the coverage area of the network managed by another network manager, the network manager part identifier in the network manager side identifier of the ue needs to be updated, and in addition, if one network element manager usually belongs to only one network manager, the network element manager part identifier in the network manager side identifier of the ue needs to be updated.

In addition, in the embodiment of the present invention, the allocation of the network management side identifier of the user equipment may be performed as needed, and when a certain user equipment needs to be managed, the network management side identifier is allocated to the user equipment. For example, according to the analysis of the historical performance measurement data, when the network manager creates a management policy and applies the management policy to a certain base station (gNB), the gNB subsequently reports the user equipment residing in the gNB to the network management side, and at this time, the network management side identifier may be allocated to the user equipment. For another example, in combination with the service of the user equipment, the information of the user equipment that has performed a certain target service is also reported to the network management side by the gNB, and at this time, the network management side identifier may be allocated to these user equipments.

In the process of distributing the network management side identifier, the network management side device (such as a network manager) does not obtain the sensitive identifier (IMSI/TMSI/IMEI/GRNTI … …) of the user equipment, so that the security of the personal information of the user equipment can be protected, privacy disclosure is avoided, and the security of the network is improved.

Referring to fig. 4, an example of an interaction procedure for allocating the network management side identifier of the user equipment is given, where:

in step 40, the NM determines the EM configuration management policy by analyzing the measurement data reported by the EM.

In step 41, the NM informs the EM of information of the target network elements (e.g. base stations/cells) involved by the management policy.

In step 42, the EM assigns a network element manager part identification uejmjd for the UE residing in the target network element it manages.

In step 43, the EM reports the information of the UE in the target network element managed by the EM (including the UE _ EM _ ID allocated to the UE) to the NM.

In step 44, the NM allocates a network manager part identifier UE _ NM _ ID to the UE reported by the EM, so as to generate a network manager side identifier UE _ Man _ ID = UE _ NM _ ID + UE _ EM _ ID of the UE.

In step 45, the NM informs the EM of the network management side identity UE _ Man _ ID of the UE.

Through the above process, the distribution of the network management side identifier of the UE under the target network element is realized.

Referring to fig. 5, another example of an interaction procedure for allocating the network management side identifier of the user equipment is shown, where:

in step 50, the NM receives the use case configuration information, and needs to deploy a specific use case, for example, a use case optimized for a specific service; NM requests EMS to obtain UE information of said special service, so as to determine target UE to be distributed with network management side identification.

In step 51, the NM obtains from the EM information of target UEs residing in the network elements it manages and performing the specific service, to instruct the EM to allocate network element manager partial identities to these UEs.

In step 52, the EM allocates a network element manager portion identification UE _ EM _ ID for said target UE residing in the network element it manages.

In step 53, the EM reports information of the target UE (including UE _ EM _ ID allocated to the UE) in the network element managed by the EM to the NM.

In step 54, the NM allocates a network manager part identifier UE _ NM _ ID to the UE reported by the EM, so as to generate a network manager side identifier UE _ Man _ ID = UE _ NM _ ID + UE _ EM _ ID of the UE.

In step 55, the NM informs the EM of the network management side identity UE _ Man _ ID of the UE.

Through the above procedures, the network management side identifier is allocated to the UE performing the target service.

Based on the method for allocating the network management side identifier of the user equipment, the embodiment of the invention can allocate the network management side identifier for the user equipment. Subsequently, the embodiment of the invention can collect the user data based on the network management side identifier.

Referring to fig. 6, a data acquisition method of a user equipment according to an embodiment of the present invention, when applied to a first element manager, includes:

step 61, the first network element manager establishes a first link between the first network manager and the first network element manager for the first user equipment, and allocates a first link identifier for the first link.

Here, the first link identifier is the first network management side identifier or a link management identifier associated with the first network management side identifier, where the first network management side identifier includes a first network element manager part identifier, which is allocated by the first network element manager to the first user equipment and is used for uniquely identifying the first user equipment, and a first network manager part identifier, which is allocated by the first network manager to the first user equipment and is used for uniquely identifying the first user equipment.

Specifically, the link management identifier associated with the first network management side identifier may be an identifier different from the first network management side identifier, and the identifier and the first network management side identifier are in one-to-one correspondence, so that the only one network management side identifier corresponding to the link management identifier may be determined through the link management identifier.

Step 62, the first network element manager sends the first link identifier and the user data of the first user equipment to the first network element manager through the first link.

Here, the first network element manager may send, through the first link, user data of the first user equipment, and carry the first link identifier, where the first link identifier is used to indicate the user equipment corresponding to the user data. In this way, the first network manager may determine, according to the first link identifier, a target device to which the user data belongs, and further manage the target device.

Through the steps, the embodiment of the invention realizes the acquisition of the user data, isolates the sensitive identification of the user equipment and improves the information safety of the user equipment.

According to at least one embodiment of the present invention, in step 62, after obtaining the user data of the first user equipment, the first network element manager sends the user data to the first network manager through the first link. Here, the first element manager may issue a user data acquisition task of the first user equipment to a node device in the first radio access network where the first user equipment is located according to a user acquisition requirement, where the identity identifier of the first user equipment may adopt the sensitive identifier of the device. And the node equipment in the first radio access network executes a specific data acquisition task, acquires the user data of the first user equipment and reports the user data to the first network element manager.

According to at least one embodiment of the present invention, in step 61, when user data of a first user equipment needs to be collected, the first network element manager may send a request message for establishing an end-to-end link to the first network manager, where the request message carries a first network management side identifier of the first user equipment; then, after receiving the acknowledgement message returned by the first network element manager, the first network element manager establishes a first link between the first network element manager and the first network manager, and allocates a first link identifier to the first link.

According to at least one embodiment of the present invention, before sending the request message, the first network element manager may create a client side of the data collection link at the ue level, and the first network manager may create a server side of the data collection link at the ue level, so that a client-server based link may be subsequently established.

In order to improve resource utilization, in this embodiment of the present invention, the first network element manager may further release the first link when determining that it is necessary to stop collecting the user data of the first user equipment. Specifically, the first network element manager may determine that the collection of the user data of the first user equipment needs to be stopped when detecting that the first user equipment moves out of the first radio access network managed by the first network element manager or receiving a notification message sent by the first network manager and used for stopping the collection of the user data of the first user equipment. Here, when it is detected that the first user equipment moves out of the first radio access network managed by the first network element manager, the first network element manager may further send a notification message for instructing to release the first link to the first network manager, so as to trigger the first network manager to release the link.

Through the steps, the embodiment of the invention reports the user data of the user equipment to the network manager based on the network management side identifier of the user equipment, thereby avoiding the leakage of the sensitive identifier of the user equipment. In addition, the embodiment of the invention creates and maintains the transmission link of the user data of the user equipment, so that various measurement data of the user equipment can be transmitted through the link, point-to-point user data acquisition of the user equipment at the granularity level is realized, and support can be provided for subsequent network service optimization and adjustment.

Corresponding to the flow shown in fig. 6, another data collecting method of a user equipment according to an embodiment of the present invention, when applied to a first network manager, includes the following steps as shown in fig. 7:

Step 72, the first network manager receives said first link identification and user data of the first user equipment via said first link.

Through the above steps, the embodiment of the present invention creates and maintains the first link for user data transmission of the first user equipment based on the network management side identifier of the user equipment, so that various measurement data of the first user equipment can be collected through the first link, and further, the first link is used for implementing network management of subsequent user equipment granularity levels.

Specifically, in step 71, the first network element manager may receive a request message for establishing the end-to-end link, where the request message carries a first network element side identifier of the first user equipment, and the request message is sent by the first network element manager. Then, the first network manager sends a confirmation message for the request message to the first network element manager, establishes a first link between the first network manager and the first network element manager, and allocates a first link identifier to the first link.

Here, the link management identifier associated with the first network management side identifier may be an identifier different from the first network management side identifier, and the identifier and the first network management side identifier are in one-to-one correspondence, and a unique network management side identifier corresponding to the link management identifier may be determined through the link management identifier.

According to at least one embodiment of the invention, prior to step 71 above, the first network manager creates a server side of the data collection link at the user equipment level.

In order to improve the resource utilization, the first network manager may release the first link when determining that it is necessary to stop collecting user data of the first user equipment. Specifically, the first network manager may determine that the collection of the user data of the first user equipment needs to be stopped when receiving a notification message sent by the first network element manager and used for instructing to release the first link, or when receiving a notification message sent by a network manager and used for stopping the collection of the user data of the first user equipment.

Step 82, determining the first user equipment corresponding to the first link identifier, and performing network management optimization processing on the first user equipment according to the network management optimization policy.

Here, the first network management side identifier corresponding to the first link identifier may be determined according to the first link identifier, and further, the first user equipment corresponding to the first link identifier is determined according to a correspondence between the locally maintained network management side identifier of the user equipment and the sensitive identifier of the user equipment. In step 82, the first network element manager may send the network management optimization policy to a radio access network (e.g., a cell/base station where the first user equipment resides) where the first user equipment resides, so as to implement network management for the first user equipment.

Through the steps, the embodiment of the invention can carry out network management on the first user equipment through the network management optimization strategy received from the first link, thereby realizing the network management of the user equipment in granularity level.

According to at least one embodiment of the present invention, before step 81, the first network element manager may further send the first link identifier and the user data of the first user equipment to the first network manager through the first link, so that the first network manager performs processing such as user policy decision based on the user data.

Referring to fig. 9, an embodiment of the present invention further provides a device management method applied to a first network manager, including:

step 91, the first network element manager receives the user data of the first user equipment from the first link, where the user data is sent by the first network element manager.

Here, the first link is a link established between the first network manager and a first network element manager for the first user equipment, and the first network manager maintains the first link by using the first link identifier, where the first link identifier is the first network management side identifier or a link management identifier associated with the first network management side identifier, and the first network management side identifier includes a first network element manager partial identifier, which is allocated to the first user equipment by the first network element manager and is used for uniquely identifying the first user equipment, and a first network manager partial identifier, which is allocated to the first user equipment by the first network manager and is used for uniquely identifying the first user equipment.

And step 92, the first network manager takes the first link identifier as an identity identifier of the first user equipment, and generates a network management optimization policy of the first user equipment based on the user data of the first user equipment.

Here, the first network manager may use the first link identifier as an identity identifier of the first user equipment, and train a preset network management model based on user data of the first user equipment to obtain a network management optimization policy; or, the user data of the first user equipment is used as an input parameter of the trained network management model, and a network management optimization strategy output by the network management model is obtained.

Specifically, the embodiment of the invention can obtain a network adjustment model for improving the end-to-end experience of the user equipment through model training by the aid of data acquisition of the user equipment and the support of technologies such as AI/ML and the like, so that the aim of reasonably allocating, adjusting and managing the network by utilizing artificial intelligence and automatic network resources is fulfilled.

Step 93, sending the first link identifier and the network management optimization policy to the first network element manager.

Through the steps, the embodiment of the invention can utilize the link established between the network manager and the network element manager aiming at a certain user equipment to collect the data of the user equipment, thereby realizing the network management of the user equipment granularity level.

Specifically, the user data includes at least one of the following data:

By means of data acquisition of user equipment and the support of AI/ML and other technologies, operators can obtain a network adjustment model for improving end-to-end experience of the user equipment through model training, so that the aims of reasonably allocating, adjusting and managing network resources automatically are fulfilled by utilizing artificial intelligence.

In the above data acquisition process, for data acquisition of User Equipment (UE), on the premise of maintaining the existing 3GPP message format to the maximum extent, NM serves as a server side and EM serves as a client side, a point-to-point link is established for each UE, and UE _ Man _ NM _ ID and UE _ Man _ EM _ ID are used to maintain UE end-to-end connection. Here, the UE _ Man _ NM _ ID and the UE _ Man _ EM _ ID constitute a link management identifier associated with the network management side identifier.

The data collection method and the device management method of the user device according to the embodiments of the present invention will be described in more detail below by using several examples.

Fig. 10 shows an example of link establishment, user data transmission, and link release, where an operator indicates a specific data acquisition requirement of the NM, and assuming that the requirement is to acquire data of a specific UE to meet a certain optimization use case, the following steps may be included subsequently:

in steps 101a to 101b, NM and EM create a server side and a client side of the UE level data acquisition link, respectively.

Step 102, for each UE that needs to be managed, EM requests NM to establish an end-to-end link.

Step 103, in response to the above request, identifying a link by using the UE _ Man _ NM _ ID and the UE _ Man _ EM _ ID, and establishing an end-to-end link for each UE. Here, the UE _ Man _ NM _ ID and the UE _ Man _ EM _ ID may be represented by UE _ NM _ ID and UE _ EM _ ID, respectively, or other identifications may be used.

Step 104, the EM sends the UE data to the NM on the corresponding link through the link established above.

Through the steps, the establishment of the UE management link can be realized.

Fig. 10 also shows a procedure for UE to manage link release, as follows:

step 105, when a certain UE moves out of the network element managed by the EM, the EM sends the information of the UE that moves out of the network element, such as the network management side identifier of the UE, to the NM.

In step 106, the EM informs the NM that the shifted-out UE's associated link needs to be released.

Of course, the above steps 105 and 106 may also be combined, so that the number of interactive messages may be reduced.

Steps 107 a-107b, NM and EM release the UE's management link, respectively. Here, the NM and EM may further release the network manager part identifier and the network element manager part identifier of the UE.

In this example, the operator may also instruct the NM to stop data acquisition of a certain UE, or remove an optimization case corresponding to a certain UE, at this time, the NM may notify the EM to release the management link of the UE, and then release the management link through a process similar to steps 107a to 107 b.

In the background of intelligently managing a wireless network and improving user Experience, starting from a wireless side to adjust wireless resources for a user in near real time is a main content of research of an open wireless access network (O-RAN), wherein Quality of Experience (QoE) uses 5G local applications with high requirements (such as cloud virtual reality) to consume bandwidth and be sensitive to delay. However, for such traffic-intensive and highly interactive applications, the current semi-static QoS framework cannot efficiently meet diversified QoE requirements, especially considering the potentially significant fluctuation of radio transmission capacity, it is generally considered that QoE estimation/prediction at the application layer helps to cope with such uncertainty, improve the efficiency of wireless resources, and ultimately improve the user experience.

In QoE optimization in O-RAN architecture and its open interface, multidimensional data can be acquired and processed through Machine Learning (ML) algorithm to support traffic identification, qoE prediction, qoS enforcement decision.

UE radio channel information, such as mobility information;

layer 2 related information of the UE, such as throughput, delay, etc.;

UE radio protocol stack status, such as PDCP buffer status;

Step 1102, the EM identifies the target UE according to the UE _ Man _ ID of the target UE, and issues the UE acquisition task to the RAN to which the target UE belongs.

And 1103, reporting the measurement data of the target UE by the RAN according to the collection task.

In step 1101, the EM reports the UE measurement data and carries the UE _ Man _ ID to identify the target UE.

In step 1105, the NM performs AI/ML model training based on the received data.

And step 1106, the NM generates an optimization strategy of the target UE according to the training result, and sends the optimization strategy to the EM by carrying the UE _ Man _ ID identification.

Step 1107, the em identifies the target UE based on the UE _ Man _ ID and sends configuration information to the RAN based on the above optimization strategy.

In step 1108, the RAN receives the configuration information and adjusts the target UE resources based on the configuration information.

Step 1109, the ran continues to report the measurement data of the target UE after the optimization policy is implemented.

Step 1110, the em reports the UE measurement data and carries the UE _ Man _ ID to identify the target UE.

And 1111, NM judges whether the expected optimization effect is achieved according to the received measurement data so as to determine whether to initiate a new round of optimization, and the data is put into an AI/ML training data set.

In step 1112, the UE drops or moves out of the RAN managed by the EM.

And step 1113, deleting the corresponding management link through the deletion process of the UE management link between NM and EM.
