What does system management provide? Log management and backup recovery functions.

5G network management has the following advantages:

(1) Web-based user interface.

(2) Unified network management (such as 4G/5G convergence).

(3) Network intelligence analysis.

(4) Open API interface.

(5) Virtualization deployment

SaaS: Software as a Service.

Platform as a service.

IaaS: Infrastructure as a service.

Hardware and software components of 5G network management;

At the bottom, the server provides basic physical resources such as CPU, memory and storage, extracts specific resources from the platform to form a virtual network management platform, and then provides network management functions to the top, including system management, self-operation and maintenance management, intelligent operation and maintenance management and wireless applications. The client can remotely access 5G network management.

Components of the 5G network management system include:

(1) System management: provides security management, log management and backup and recovery functions.

(2) Self-operation and maintenance management: providing application performance management.

(3) Intelligent operation and maintenance: provide advanced applications of alarm root cause analysis and network intelligent analysis, and develop automation platform and global policy management.

(4) Wireless application: providing data acquisition, northbound interface management, network intelligence analysis, wireless configuration management and wireless network elements.

Management, wireless network operation and maintenance monitoring, signaling tracking analysis, network element open upgrade center and general network element management.

(5) Public * * * application: providing network-wide alarm and topology management.

Common functions of 5G network management include:

(1) task description: task background and plan data table.

(2) Network planning: planning data sheet.

(3) Engineering survey: simulating engineering survey.

(4) Equipment installation: simulate hardware equipment installation.

(5) Equipment maintenance: data configuration and parameter adjustment.

(6) Business verification: perform business verification according to the configured data to complete the task.

Task 2: Configure Data

Briefly describe the basic process of opening PnP base station.

Step 1: Confirm whether DHCP relay function is enabled in transmission.

Step 2: UME network management version is put into storage.

Step 3: UME network management foreground configuration production.

Step 4: UME network management creates and starts the station opening task, and tracks the station opening task.

Step 5: Power on the front desk.

Step 6: Track whether the opening task of UME station is completed.

General parameters:

(1)PLMN: public land mobile (communication) network.

PLMN=MCC + MNC

(2)PCI: physical cell ID, the value range is 0 ~ 1007.

PCI = PSS+3 SSS (PSS is 0 ~ 2, SSS is 0 ~ 335).

(3)SCTP local port number/remote port number: SCTP protocol port number, the local port number is usually 384 12, and the remote port slogan is usually 38422.

(4) Center frequency point: The cell uses frequency points to determine the center frequency of the cell.

(5) Frequency bandwidth: cell bandwidth. The frequency range of FR 1 band is 450 MHz ~ 6 GHz, also known as sub 6 GHz band. The frequency range of FR2 band is 24.25 ~ 52.6 GHz, which is usually called millimeter wave. The maximum available bandwidth of FR 1 band is 100MHz, and that of FR2 band is 400 MHz. At present, the network 5G mainly adopts 30 kHz subcarrier spacing, and the bandwidth is 100 MHz. The actual configuration is determined according to the 5G scenario.

(6) Downlink resource ratio per 10 ms: the ratio of downlink in the whole radio frame. It is related to frame structure and symbol ratio.

(7)TAC tracking area: There is AMF distribution, and several cells form a TAC, which is the basic range of paging.

(8) Cell ID: the value range is 0 ~ 255, and the cell ID in a base station is not duplicate, which is planned by the group.

Data configuration:

1. Global parameters:

"MCC": mobile country code, unique in the world. China is 460.

"MNC": mobile network code. The only operators in China, such as China Mobile, are all born after 00.

"OMC server address": server address, filled in according to the actual server address.

"OMC prefix length": filled in according to the network plan.

"SNTP server IP address": SNTP server is used for time synchronization, and general operators and provincial companies will have SNTP servers.

"Time Zone": East Zone 8.

Site configuration parameters:

"Subnet ID": filled in according to the plan.

"Network Element ID": filled in according to the plan, and the network element ID cannot be duplicate.

"Base Station Name": the base station name is not needed, and can be planned manually.

"Network Element Model Type": CUDU, unique value.

"Network element IP address": the network element address of the base station, which is used for communication with the network management.

3. Transmission network configuration:

"IP address of network element": filled in according to the scheme.

"IP prefix": fill in according to the plan.

"IP gateway address": fill in according to the scheme.

"VLAN identification used by IP layer": used to isolate IP layer. If multiple IPS are configured, multiple VLANs are required (for example, separating the network management IP from the service IP).

"Even number": fill in as planned.

"SCTP local port number/remote port number": 384 12 for all netcom.

"Local Address/Remote Address": to be filled in according to the plan. The local address is the IP address of the network element and the remote address is the core network.

IP address of AMF.

"Static routing configuration (destination IP address)": This address is the IP address of the core network AMF.

"Static routing configuration (static routing prefix length)": filled in according to the plan.

"Static routing": When the remote IP addresses of the core network and the gateway are not in the same network segment, they need to be configured to be the same as the remote address.

A network segment, otherwise it will not work.

4. Unit configuration:

"Community ID": a unique community ID, which is filled in according to the plan. Generally, it is planned by the group in a unified way.

"Physical cell identification code": the value range of PCI is 0 ~ 1007. In one example, multiplexing cannot be repeated, and the PCI mod 3 of adjacent cells is not equal.

"Tracking Area Code": unique in AMF and planned by the core network.

"Band indication": indicates the frequency band used by the cell.

"Frequency bandwidth": indicates the cell bandwidth.

"Tiling service type": configured according to the scene.

"Slice Partition": filled in according to business.

Task 3: Business Debugging

After completing the configuration of 5G data, how to judge whether the configuration of 5G data is correct and whether the 5G base station can be turned on normally. This requires service debugging to test whether the service can run normally, so as to judge whether the 5G base station is opened normally.

Question 1: What is eMBB? What scene is it mainly used in?

A: eMBB is enhanced mobile bandwidth. EMBB mainly serves the consumer Internet, such as AR/VR and HD video.

Broadcasting, 8K HD, etc. Requires high network speed and needs the support of large bandwidth.

Question 2: What is uRLLC? What scene is it mainly used in?

A: uRLLC is a low-latency and high-reliability communication method. The main scenes of uRLLC, such as car networking, unmanned aerial vehicles, industrial control, telemedicine and so on. The requirements for low delay and reliability of the network are very high.

Question: What is mMTC? What scene is it mainly used in?

A: Large machine connection. MMTC mainly serves the Internet of Things, such as smart cities (water meters, electricity meters, gas meters, street lamps, traffic lights), smart homes (cigarettes, lights, door locks, household appliances), and smart agriculture.

It is very important for students to know what kind of verification to use in what scenarios.
