Detailed Description

The method of the embodiment of the present application may be applied in Long Term Evolution (LTE), a fifth generation mobile communication (5generation, 5g) system, or a future mobile communication system.

Currently, the third Generation partnership project (3 rd Generation partnership project,3 gpp) defines two schemes for 5G New air interface (New Radio, NR) networking, namely an independent networking SA and a non-independent networking NSA.

SA refers to a5G independently deployed control plane and user plane, and a5G independently carries control signaling and user plane data.

In the networking mode of the SA, there are many options for the operator to select, for example, option 1, option 2, option 5, and option 6 may be provided in the SA.

Illustratively, fig. 1 shows a networking mode of SA option 2. The 5G core network is connected with the 5G base station through a next generation Network (NG) interface in a straight line, SA signaling and data are transmitted, and an independent 5G networking is formed.

Fig. 2 is a networking mode of SA option 5, which is different from SA option 2 in that, in the networking mode of SA option 5, a 4G base station may be upgraded to an evolved LTE (LTE) access, and NSA signaling (such as registration and authentication) between a5G wireless network and a core network transfers the LTE through the 4G base station.

Fig. 3 is a5G network architecture of an SA. The network architecture includes a terminal device, AN Access Network (AN), a core network, and a Data Network (DN). The access network device is mainly used for realizing functions of a wireless physical layer, resource scheduling and wireless resource management, wireless access control, mobility management and the like; the core network device may include a management device and a gateway device, the management device is mainly used for device registration, security authentication, mobility management, location management, and the like of the terminal device, and the gateway device is mainly used for establishing a channel with the terminal device and forwarding a data packet between the terminal device and an external data network on the channel; the data network may include network devices (e.g., servers, routers, etc.), and is mainly used for providing various data service services for the terminal devices. The description is given by taking an access network, a core network and a data network in 5G as examples.

The access network in the 5G may be a radio access network (R) AN, and the (R) AN device in the 5G system may be composed of a plurality of 5G- (R) AN nodes, and the 5G- (R) AN nodes may include: an access network of the 3GPP, an access network of the non-3 GPP, such as an Access Point (AP) of a WiFi network, a next generation base station (which may be collectively referred to as a new generation radio access network node (NG-RAN node), where the next generation base station includes a new air interface base station (NR nodeB, gNB), a new generation evolved base station (NG-eNB), a Central Unit (CU), a Distributed Unit (DU), a gNB in a separate form, and the like), a transmission point (TRP), a Transmission Point (TP), or other nodes.

The 5G core network (5G core/new generation core,5 GC/NGC) includes multiple functional units such as an access and mobility management function (AMF) network element, a Session Management Function (SMF) network element, a User Plane Function (UPF) network element, an authentication server function (AUSF) network element, a Policy Control Function (PCF) network element, an Application Function (AF) network element, a unified data management function (UDM) network element, a Network Slice Selection Function (NSSF) network element, a network function (network element) network element, and the like.

The AMF network element is mainly responsible for services such as mobility management, access management and the like. The SMF network element is mainly responsible for session management, dynamic host configuration protocol function, selection and control of user plane function and the like. The UPF network element is mainly responsible for routing and forwarding data packets, filtering messages, and performing quality of service (QoS) control related functions, etc., which are externally connected to a Data Network (DN) and a user plane. The DN mainly provides services for the user equipment, such as providing mobile operator services, internet services or third party services. The AUSF network element is mainly responsible for authentication functions of the terminal equipment and the like. The PCF network element is mainly responsible for providing a unified policy framework for network behavior management, providing policy rules for control plane functions, obtaining registration information related to policy decisions, and the like. It should be noted that these functional units may work independently, or may be combined together to implement some control functions, such as access control and mobility management functions for access authentication, security encryption, location registration, etc. of the terminal device, and session management functions for establishment, release, and modification of a user plane transmission path, etc. The UDM network element is a unified user data management and is mainly used for storing the subscription data of the user equipment.

As shown in fig. 3, the 5G core network is connected to the 5G base station NG interface and transfers NSA signaling and data. The 5G radio air interface and Radio Resource Control (RRC) signaling, broadcast signaling, and data are transferred through the 5G NR. Wherein, the en-gNB is an E-UTRA-NR Generation NodeB, and mainly describes the gNB connected to a 4G cellular side core (EPC), namely the gNB is connected to the EPC and the 5GC at the same time. A next generation evolved node B (ng-eNB) mainly describes an eNB connected to a 5GC, i.e., the eNB is connected to both the EPC and the 5GC.

NSA refers to the independent deployment of the control plane by 4G, with 4G carrying control signaling. The 5G and the 4G jointly deploy the user plane, and the 5G and the 4G carry user plane data. Or the 5G is independently deployed with the user plane, and only the 5G carries the user plane data.

In the networking mode of NSA, there are many options for the operator to select, for example, option 3 series, option 4 series, option 7 series, option 8, and the like may be provided in NSA.

Illustratively, fig. 4 illustrates a networking approach of the NSA option 3 series. Fig. 5 shows a networking scheme of the NSA option 7 series. The 5G is attached to a network architecture in which the 4G base station operates, NSA signaling (such as registration, authentication, and the like) between the 5G wireless network and the core network is transmitted through the 4G base station, and the 5G cannot operate independently.

Fig. 6 is a network architecture of NSA. As shown in fig. 6, a 4G core network is introduced into 5G, 5G is used for high-speed data transmission, and NSA signaling is carried by 4G. RRC signaling, broadcast, etc. signaling for the 5G radio air interface may be transferred by 4G, with data transferred through 5G NR and 4G LTE.

In specific application, a5G new air interface independent networking mode needs to independently deploy a5G end-to-end network, and a5G base station and a core network are newly built, so that the operation can be independent of 4G. The existing 4G network can be used in a non-independent networking mode, and some 5G devices are transformed, upgraded or added, so that the network can enable users to experience the ultrahigh network speed of 5G, and the existing devices are not wasted. In the process of transition from 4G to 5G, there are cases where parallel application of SA, non-NSA or SA _ NSA is supported, and in some network systems, there are network architectures supporting one or more of SA, non-NSA or SA _ NSA.

The existing standard protocol uses the same set of model for the management of SA and NSA modes of gNB, and only distinguishes between EP interfaces, does not distinguish between SA and NSA, and does not distinguish between 4G network systems or 5G network systems, so that data of SA and NSA cannot be classified respectively, and data of 4G network systems or 5G network systems cannot be classified respectively. The operator cannot perform resource control on the cell of the SA _ NSA base station based on the specific performance condition of the SA or the NSA, and the situation that the resource control is unreasonable easily occurs.

The following describes the technical solution of the present application and how to solve the above technical problems in detail by specific embodiments. The following embodiments may be implemented independently or in combination, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 8 is a schematic flowchart of a network management method according to an embodiment of the present application, and as shown in fig. 8, the method includes:

s801: the network data receiving equipment sends a network data subscription request to the domain network management equipment, wherein the network data subscription request carries indication information; the indication information is used for indicating the domain network management equipment to report network data corresponding to the network networking information, and the network networking information comprises at least one of network networking options or network systems; network networking options are used to describe one or more of the following: SA, NSA or SA _ NSA.

In this embodiment, when the network data carries the indication information in the request, the network data may be used to instruct the domain network management device to report network data related to one or more of SA, NSA, SA _ NSA, or network standard. When the indication information includes different content, different network data may be requested correspondingly, and specific reference may be made to the description in the explanation of the indication information, which is not described herein again.

In a specific application, the network data receiving device may send a network data subscription request to the domain network management device based on a request of a user, so as to obtain network data related to the indication information, which meets a user requirement. The network data receiving device may also send a network data subscription request to the domain network management device by itself, so that dynamic resource control and the like may be further implemented based on the network data sent by the domain network management device.

S802: and the domain network management equipment determines the network data corresponding to the indication information according to the network data subscription request.

In a possible implementation of the embodiment of the application, the domain network management device may analyze the network networking information of the collected network data, and determine the network data corresponding to the indication information. In this manner, the domain network device does not need to communicate with the corresponding network element based on the network data subscription request.

For example, the domain network management device may determine, according to the network networking information of the network data generation object, network data corresponding to the indication information; the network data generating object includes one or more of the following: terminal equipment, a cell and a network element.

For example, taking the network data generation object as the network element, when the network networking option of the network element is hybrid networking SA _ NSA and the network data is network performance data of a cell, the domain network management device may determine the network networking option of the network data according to an NSA _ DC switch (NSA _ DC dual connectivity switch) of the cell corresponding to the acquired network data. Such as: the NRCellCU cells are arranged under the 5G base station, when the domain network management equipment receives the statistic information of the early cell switching of the NRCellCU, the NSA _ DC switch of the NRCellCU cells can be inquired, and if the NSA _ DC switch indicates SA, the statistic information of the early cell switching is network data under the SA networking.

Or, the domain network management device may determine the networking option of the network element according to the connection information included in the network element. For example, if the 5G base station includes an EP _ S1U (that is, the 5G base station is connected to the SGW network element of the 4G core network), it may be determined that the network networking option of the corresponding network element is NSA, and the network networking option of the network data may be further determined according to the network networking option of the network element corresponding to the network data.

It can be understood that, in the case that the network data generation object is a cell, the domain network management device may query the configuration data or networking architecture of the cell or network element to obtain the network networking option of the network data. In the case that the network data generation object is a terminal device, the domain network management device may determine the network networking option of the network data according to the access type of the terminal device.

In another possible implementation of the embodiment of the present application, as shown in fig. 8, S802 optionally includes: s8021, the domain network management device sends the network data acquisition requirement information including the indication information to the corresponding network element. S8202, the network element sends the network data corresponding to the indication information to the domain network management device.

That is, the domain network management device may send the indication information to the corresponding network element, determine, by the corresponding network element, network data corresponding to the indication information, and send the network data to the domain network management device.

In the embodiment of the present application, the number of the corresponding network elements may be one or more. The corresponding network element may be indicated in the network data subscription request, for example, if the network data subscription request carries an identifier of one or more network elements, the corresponding network element may be a network element corresponding to the network element identifier carried in the network data subscription request; or, the network data subscription request carries the identifiers of the one or more subnetworks, and then the corresponding network element may be a network element included in the one or more subnetworks. The corresponding network element may also be all or part of the corresponding network elements in the domain network management device, and the like, so that the network data subscription request may not carry the identifier of the relevant network element, and the domain network management device determines the corresponding network element according to the actual requirement. The embodiment of the present application does not specifically limit a corresponding network element.

After receiving the network data acquisition requirement information including the indication information, the corresponding network element may send the network data related to the indication information to the domain network management device. For example, when the network element sends a PRB Usage to the domain network management unit, the network element needs to carry network data acquired in a scenario that the PRB Usage is an SA, an NSA, an SA _ NSA, a 4G base station, or a5G base station.

S803: and the domain network management equipment sends the network data corresponding to the indication information to the network data receiving equipment.

For example, the domain network managing device may send a network data file or a data stream channel for writing network data to the network data receiving device. Suitably, the domain network management device may generate a network data file or a data stream channel corresponding to the indication information; the network data file or the data stream channel carries indication information; and writing the network data into the corresponding network data file or starting a plurality of data flow channels for writing the network data according to the indication information corresponding to the network data.

In the embodiment of the present application, the network data file or the data stream channel includes, but is not limited to, one or more of the following: SA5G base station performance files, NSA5G base station performance files, SA _ NSA5G base station performance files, SA 4G base station performance files, NSA 4G base station performance files, SA _ NSA 4G base station performance files, SA performance files, NSA performance files, SA _ NSA performance files, and the like.

In this embodiment of the application, when the indication information includes network networking splitting information, the domain network management device may generate network data files or data stream channels of all network networking options or network types supported in the network, where each network data file or data stream channel carries a network networking option identifier or a network type identifier corresponding to the network data file or data stream channel. When the indication information includes a network networking option identifier, or a network system identifier, or includes both a network networking option identifier and a network system identifier, the domain network management device establishes a network data file or a data stream channel corresponding to the identifier included in the indication information, and each network data file or data stream channel carries the network networking option identifier or the network system identifier corresponding to the network data file or the data stream channel.

To sum up, in this embodiment of the application, the domain network management device may send, based on the indication of the network data receiving device, the network data corresponding to the indication information to the network data receiving device. The network data receiving device may obtain network data corresponding to one or more of the network networking options or the network standards, so that the operator may perceive and evaluate network performance under different network networking, or may subsequently implement reasonable resource control and the like based on the specific conditions of one or more of the network standards or the network networking options.

The second embodiment of the present application provides a specific network management method, and the second embodiment of the present application may adopt an interaction process similar to that in the first embodiment of the present application. Specifically, in the second embodiment of the present application, the indication information includes a network networking option identifier, a network format identifier, or a network networking identifier and a network format identifier.

In the embodiment of the application, when the indication information includes the network networking option identifier, the network networking option needing to be subscribed is made clear in the indication information. For example, when the indication information includes the SA identifier, network data of the SA may be collected subsequently; when the indication information comprises the NSA identification, subsequently collecting network data of the NSA; when the indication information includes the SA _ NSA identifier, network data of the SA _ NSA may be collected subsequently; when the indication information comprises the SA identifier and the NSA identifier, the network data of the SA and the network data of the NSA can be collected subsequently; and the like.

When the indication information contains the network type identifier, the network type to be subscribed is clarified in the indication information, for example, when the indication information contains the 4G identifier, the network data of the 4G base station can be collected subsequently; when the indication information comprises the 5G identification, the network data of 5G can be collected subsequently; and the like.

When the indication information contains a network networking identifier and a network system identifier, a network networking option of a certain network system needing to be subscribed is determined in the indication information. For example, when the indication information includes the SA identifier and the 5G identifier, the SA network data of the 5G base station may be collected subsequently; when the indication information comprises the NSA identifier and the 4G identifier, acquiring NSA network data of the 4G base station subsequently; and the like.

The specific implementation of S802 may be: the domain network management equipment determines network data acquisition demand information of a corresponding network element according to the network data subscription request, wherein the network data acquisition information comprises indication information; the domain network management equipment sends network data acquisition demand information to a network element or a management unit of the network element; the network data acquisition demand information is used for indicating the network element or a management unit of the network element to send network data corresponding to the indication information; and the domain network management equipment receives network data corresponding to the indication information sent by the network element or the management unit of the network element.

That is, in this embodiment of the application, the domain network management device may determine, according to the network networking identifier and/or the network system identifier included in the indication information, network data acquisition information corresponding to the identifier included in the indication information, and further acquire network data corresponding to the identifier included in the indication information.

A third embodiment of the present application provides a specific network management method, and an interaction process similar to that in the first embodiment of the present application may be adopted in the third embodiment of the present application. Specifically, in the third embodiment of the present application, the indication information includes network networking splitting information.

The specific implementation of S802 may be: the domain network management equipment determines network data acquisition demand information of a corresponding network element according to the network data subscription request, wherein the network data acquisition information comprises indication information; the domain network management equipment sends network data acquisition demand information to a network element or a management unit of the network element; the network data acquisition requirement information is used for: indicating the network element or a management unit of the network element to respectively send corresponding network data according to a network networking mode or a network standard; the domain network management equipment receives network data sent by a network element or a management unit of the network element.

That is, in this embodiment of the present application, a network element may determine, according to network networking splitting information, network data corresponding to a network networking mode or a network system supported by the network element, and send the network data to a domain network management device according to a classification.

Fig. 9 is a schematic flowchart of a network management method according to a fourth embodiment of the present application, and as shown in fig. 9, the method includes:

s901: the domain network management equipment receives a network networking configuration request; the network networking configuration request is used for requesting the domain network management equipment to configure a network networking option for the network element or configure a network networking mode selector switch for the cell of the network element.

S902: and the domain network management equipment configures network networking options of the network elements or configures a network networking mode switch of the cells of the network elements according to the configuration request.

In this embodiment of the present application, the domain network management device may receive a network networking configuration request from the network data receiving device, and further, the domain network management device may configure a network networking option of a network element or configure a cell configuration network networking mode switch of the network element based on the network networking configuration request.

In a specific application, the network networking configuration request may be a request for creating or modifying a management object, and the management object may be one or more of a sub-network, a network element, or a cell. The network networking configuration request may also be referred to as a configuration request or a network element configuration request, etc.

In one possible implementation, the network networking configuration request may include an identification of a network networking option, where the network networking option is used to describe one or more of the following: SA, NSA or SA _ NSA. The domain network management device can flexibly configure the network networking options of the corresponding network elements, thereby facilitating the subsequent differentiation and statistics of the network data of different network networking.

In this embodiment of the present application, the number of network elements configured by the domain network management device may be one or more. The configured network element may be indicated in the network networking configuration request, for example, the network networking configuration request carries an identifier of one or more network elements, and the configured network element may be a network element corresponding to the network networking configuration request carrying the network element identifier; or, the network networking configuration request carries the identifier of one or more sub-networks, and the configured network element may be a network element included in one or more sub-networks. The configured network elements may also be all or part of the corresponding network elements in the domain network management device, and the like, so the network networking configuration request may not carry the identifier of the network element or the sub-network, and the domain network management device determines the network elements to be configured according to the actual requirements. The embodiment of the present application does not specifically limit a corresponding network element.

After determining the network element to be configured, the domain network management device may send a network element configuration request to the network element to be configured, where the network element configuration request carries an identifier of a network networking option in the network networking configuration request, and then the network element may adapt to configure the network networking option according to the identifier of the network networking option.

In another possible implementation manner, the network networking configuration request may include an identifier of a cell network networking mode switch, and the domain network management device may determine a cell included in the network element and configure the cell network networking mode switch in a management object of the cell. The cell network networking mode switch can dynamically switch the support capability of the cell to the network networking mode, and is favorable for fully utilizing network resources according to the real-time network performance condition.

For example, taking the example that the cell network networking mode switch is an NSA _ DC switch, the domain network management device may determine a cell included in a network element or a sub-network, configure the NSA _ DC switch in a management object of a corresponding cell, and optionally, may also send the configuration condition to the corresponding network element.

In specific implementation, the domain network management device may introduce a network deployment scenario configuration interface of the base station in a northbound manner, where the network deployment scenario configuration interface carries an identifier of a network networking option, so as to implement configuration of the network networking option of the network element; or, the domain network management device may introduce a configuration interface of a cell network networking mode switch in the north direction, and the cell network networking mode switch may be used to switch the capability of the cell to support the SA or the NSA.

In summary, in the embodiment of the present application, the domain network management device may implement flexible configuration of a network networking option of a network element, or may implement flexible configuration of a cell configuration network networking mode switch of the network element, so that the support conditions of the SA and the NSA in the network may be adjusted based on the flexible configuration.

Optionally, the domain network management device may further collect network performance data reported by the network element, and determine whether to reconfigure the cell network networking mode switch of the cell based on the collected network performance data, that is, as shown in fig. 9, an optional step S903: and the domain network management equipment acquires network performance data reported by the network elements. Optional step S904: and the domain network management equipment judges whether to reconfigure the cell network networking mode selector switch of the cell according to the network performance data of the network element.

For example, according to the collected network performance data, the domain network management device detects that the terminal PRB resource of the SA is insufficient and the NSA _ DC switch of the corresponding cell is in an on state, and may configure the NSA _ DC switch of the cells to be off and the cell resource is used by the terminal of the SA. Thereby, a reasonable resource allocation can be achieved.

Or, the domain network management unit device detects that the terminal PRB resources of the SA are redundant but the PRB resources of the NSA terminal are insufficient according to the acquired network performance data, and if the corresponding cell NSA _ DC switch is in the off state, configures the NSA _ DC switches of these cells to be on, and may use part of the cell resources for the NSA terminal. Thereby, a reasonable resource allocation can be achieved.
