• 7. 4G Overview The RAN provides access links between UE and the EPC network. UE: UE includes the end-user terminals such as cell phones and PCs Radio Node: The Radio Node corresponds to eNodeB in 3GPP specifications. It controls the radio connections with connected UE and manages the cell resources, including connection mobility control. eNodeB is a part of LTE radio access network and is the component that allows UEs to connect to the LTE network. The RAN access links are divided into the following planes: User plane: It carries the end-user payload traffic of voice, video, or any data traffic. Control plane: It carries control signaling for user plane traffic. IP Transport Network: The IP transport network provides interconnection between the eNodeBs and the nodes in
• 8. 4G Overview EPC: EPC is the IP-based core network between the RAN and other networks. On the user plane, EPC connects the RAN with the SGW, and on the control plane, with the MME. MME: Mobility Management Entity & deals with the EPC control plane, Its role is to manage sessions, authentication, paging, mobility, bearers and roaming. SGW: Serving Gateway & deals with routing and forwarding of user data packets. It also routes incoming and outgoing IP packets for better system collaboration and serves as an anchor for the UE when it moves from one eNodeB to another. PDN-GW: Packet Data Network Gateway. It is the network node that connects the EPC to external IP networks. It routes packets to and from external IP networks. ENM: Ericsson Network Manager provides a Unified Network Management for Radio, Core and associated Transport nodes. NMS: Network Management Station that manages more than one subnetwork
• 9. Interfaces of the 4G eNodeB S1: The S1 interface connects the LTE and the EPC for both the user and the control planes. It has two parts: the S1-C, belonging to the control plane and the S1-U, belonging to the user plane. The S1-C connects the eNodeB to the MME and is based on IP transmission. It transmits signaling messages of the radio network layer of the LTE RAN through the Stream Control Transmission Protocol (SCTP)/IP stack. The S1-U connects the eNodeB to the S-GW through the GTP/UDP5/IP stack. X2: Interface provides connectivity between two or more eNodeBs. There are two parts of the X2 interface, the X2-C, the interface between the control planes of eNodeBs, and the X2-U, the interface between the user planes of eNodeBs. The X2-C and the X2-U have the same structure as the S1 interface. Mul: Interface that communicates with the OSS/ENM and carries traditional operation and maintenance data, such as alarms, performance events and software upgrades.

See example below Integrate BBU & Check Integration Log for Progress 1. The RBS Summary File will be used again to continue to Integrate the BBU. 2. Here the RAN HW & Tx definitions are done at BBU with respect to site configuration. 3. BBU will be restarted & the onsite configuration files will be installed. 4. Continue to check the Auto Integration Log Box for progress of integration. Integrate BBU 1. Once the initial loading of the OSF is loaded to about 65% Software Download and Install Complete appears at the bottom of the screen, the option to Integrate the BB will become available. 2. Click on “Integrate”.
• 57. Baseband Onsite Commissioning Verify that the Onsite Commissioning is completed successfully. 1. After 10-15 min the Commissioning will be finished. 2. Once the configuration file is completed,the network loader should be at 70% 3. Example below: 4. In order to confirm that the integration completed successfully, Check the LED indications lights on the board, Verify that both the and the TNC LEDs are solid GREEN. 5. Go to web browser on the https://169.254.2.2/ea.html page & Verify that the node status as “Node is working”. 6. Onsite Commissioning ends here. Further steps can be done Onsite or Remotely.
• 58. Baseband Commissioning/Configuration Scripts 1. Baseband will be having 10 different scripts i.e 3 OSF & 7 Remote files/scripts. 2. RBS Summary, Site Basic & Site Equipment scripts are for Onsite Commissioning. Also know as OSF i.e Onsite Files. These are xml files. 3. TN, RN, Post Install scripts can be run in both Onsite or via ENM when Remote connectivity is through. These are know as mos or remote files/scripts. 4. ARNE scripts to be run only Remotely in ENM. 5. RBS Summary- It contains information of SW & which Site Basic & Site Equipment script to define. 6. Site Basic- It contains information of all Tx related information of the site , node fingerprint & node maintenance username & password. 7. Site Equipment- It contains information of Hw to be define & how Hw will connect to BBU. 8. TN- It contains info about Sync, Clock, QoS & additional Tx info. 9. RN- It contains info about plmn, Enb Id, Carrier power, TxRx, earfcn, PCI , Cell BW, TAC, Lat-Long, MME , Relation to other technology, etc. 10.Post Install- It contains additional info of node.
• 59. Baseband Remote Integration via ENM The following steps must be executed by the Remote engineer after Onsite Commissioning is done & BBU defined in ENM. 1. Upload with ftp the mos Delta Moshell script to ENM. 2. Open the ENM Application Launcher and click on Shell Terminal on Scripting APP. 3. RESULT: A shell(Advance MO Shell) will be displayed as below: 4. Login to the BBU: ACTION: Type: amos lt all RESULT: Login to BBU via shell Terminal & configuration of the node is loaded in it till which it was configured onsite. 5. Load the remaining mos script/file in the BBU: ACTION: Type: run /.mos lt all RESULT: The new configuration which was in mos script is loaded in the node . Through this step all TN, RN & Post Install mos scripts/files to be run & configurations in each mos scripts are loaded to BBU one by one. 6. After the configuration and in order to assure the fallback procedure, create a Configuration Version (i.e backup) in BBU: ACTION: Type: cvms RESULT: New CV Backup is created with respect to the current configuration of the Baseband.

• 62. MoShell is a text-based O&M client providing access to the following services: — Configuration Service (CS) — Alarm Service (AS) — Performance Management (PM) Service — Log Service (LS) — OSE shell (COLI) — File transfer (File Transfer Protocol (FTP) / Hypertext Transfer Protocol (HTTP)) Access to all services is supported both in secure mode (secure Common Object Request Broker Architecture ( CORBA), Secure Shell (SSH), Secure File Transfer Protocol (SFTP)) and unsecure mode (unsecure CORBA, Telnet, FTP). Advanced MO Scripting (AMOS) provides a Command-Line Interface (CLI) towards supported Connectivity Packet Platform (CPP), and Transport-based Network Elements. MoShell architecture as shown. BBU is Cello packet platform i.e CPP node, & It have various access methods for different services: — For Managed Services like CS, CORBA is used. — For the command shell, ssh or telnet is used. — To collect PM XML ROP files FTP/SFTP is used. AMOS is part of ENM package for O&M of BBU. What is MoShell
• 63. MO Concept of RAN Nodes - The MO i.e Managed Object is a way of modelling resources in a CPP node. - The purpose of the Management Object (MO) is to interface towards the various O&M services described. - The MOs are organized in a hierarchical structure as FDN/LDN/RDN as below: - Each MO instance is uniquely identified in the node by its Local Distinguished Name (LDN). - The highest MO in a node, the so-called root MO is the ManagedElement. This MO represents the whole node. - There is only one instance of the ManagedElement MO in the node and it is referenced by the LDN: ManagedElement=1 - The string at the left of the equal sign is called the MO class (or MO type) and the string at the right of the equal sign is called the MO identity. In the case of the root MO, the MO class is ManagedElement and the identity is 1. - If an MO is located further down in the MO tree, the LDN must contain the MO classes and identities of all the parents of that MO, in a sequence going from the root MO down to the MO in question. See example below:
• 64. RAN O&M via MoShell/AMOS Functionality Alarm Service(AS) -The list of active alarms can be retrieved with the commands al to show an overview. alt to show overview + Date & Time ala the same as al, with more details. Configuration Service(CS)- MoShell supports the following 6 operations from the configuration service: Performance Management (PM) Service pmr to show an overview of KPI trend of node. Minimum time interval is 15mins statistic ROP. Produce PM KPI reports. pmx to show counters of KPIs values extractad from the statistic ROP files.

• 67. RAN Node Backup & Restore.
• 68. Baseband Configuration Backup Baseband Configuration Backup can be taken via any of below three process: — Creating Onsite Configuration Version/ Backup at node by connecting directedly to it & transferring the CV to local terminal for future reference. Command- cvget “cvname”. — Creating Configuration Version/ Backup at node by connecting BBU through ENM-AMOS & storing the CV in ENM-AMOS terminal for future reference. Command- cvget “cvname”. — Creating Configuration Version/ Backup at node(s) via ENM- SHM i.e Software Hardware Manager. Here we can take backup of multiple nodes at a time & we can schedule the process too. After job is done it is saved in ENM for future reference. Example of a Site backup after completing the above steps. For site restoration we should refer the latest backup. Site Backup will be having 2 files as below On opening the backupinfo.xml of a Site backup we will be having three details as below: 1. Backup Version or Name. 2. Site id of Backup taken. 3. Available Baseband Software level at the time of backup taken. During restoration with this configuration backup need to have same Software.
• 69. Baseband Restoration from Configuration Backup 1. If any site BBU gets faulty then site can be restored with its last taken “Configuration Backup” through onsite engineer. 2. The Site Engineer reaches the site with the Configuration Backup and the software/upgrade package as noted during the CV creation. 3. The new hardware installed on the site is powered on. The laptop is configured with an IP address of 169.254.2.1, a subnet mask of 255.255.255.0 and a default gateway of 169.254.2.2. 4. Connect node LMT port to laptop that has server application for sftp. Start laptop SFTP server as done during commissioning time. 5. From the web browser of the Laptop, the following URL is accessed. https://169.254.2.2/autointegration.html. IP to put in Auto integration is 169.254.2.1. User & password as rbs/rbs. 6. The attached Summary File is used to define the correct Software Package Zip File and the Backup Name. 7. The software package and the summary file itself should be present in the Folder as defined on the SFTP server. 7. Enter the SFTP server file path of Restore File in the ‘Site Installation File’ text field 8. After this proceed to “Download files”, Once the files are download the node is ready to log in. 9. Install License Key File. The node is ready to be brought into service. 10.The ease of restoration of the BBU to the last known configuration that was available during backup creation is a simple, quick, and robust procedure
• 70. Easy HW Replacement & Site Restoration Background Issue — Complicated and time consuming manual HW replacement procedure as described in previous step. Solution — Easy HW Replacement introduces automated replacement of Basebands in field based on Zero Touch Integration, with ENM. — The configuration from the replaced HW is automatically included on the new HW by restoring node CV. Befits — Solution to increase network performance by fast replacement of Basebands — No need for integration competence or laptop at site. — Faster node recovery & Less time spent on site. Prerequisites The network must be set up i.e, — The end-to-end customer network must be setup for Zero Touch Auto-integration using DHCP — DHCP Server: ENM to act as DHCP Server — DHCP Relay: Site router configuration to act as DHCP Relay — LTE and NR should run in the single Baseband Network Operation Management must have: — Backup shall regularly be uploaded in ENM-SHM for all nodes — License Key Files for all nodes shall always be stored in ENM-SHM — Operational SW package shall always be stored in ENM-SHM
