This feature is based on LTE433: Cell Trace and includes extensions for IMSI number additions for the cell trace data. The feature provides detailed subscriber oriented information at call level for one or more specific mobile(s). The operator can activate Network Monitoring subscriber and equipment tracing for a limited period of time for specific analysis purposes, .e.g. for root cause determination of a and Maintenance malfunctioning mobile, advanced troubleshooting, optimization of resource usage and quality, RF coverage control and capacity improvement, dropped call analysis or E2E procedure validation. System maintenance is responsible for maintaining computing platform of the Flexi LTE BTS. It consists of four internal systems: supervision system, internal alarm system, recovery system and diagnostic system. The supervision system performs continuous Network Monitoring checking and testing in order to detect irregularities, the alarm system monitors the procedural behaviour of SW tasks, the recovery and Maintenance system tries to eliminate the fault effects and spreading of the faults and the diagnostic can be activated in addition to support the trouble-finding-phase of the fault handling.

In the flat architecture of the LTE, meaning multiple S1 and X2 interfaces this is more important than e.g. in WCDMA system where only few common interfaces are in place. Depending on the failed connection and/or node, a single failure can cause in worst case up to 1000-2000 or even more alarm events. By using alarm correlation instead of this big amount of alarms only a dedicated alarm is send to the operator in case of interface problems.

The BTS Site Browser allows quick discovery, monitoring and configuration of multiple BTS's without need of constant connect/reconnect to individual BTS's. Timing advance measurements can be used by the operator for network planning and optimization exercises. It is possible to locate Network Monitoring high and low traffic areas in the cell, to geographically plot a generic user distribution in the cell, to obtain dropped call statistics etc. and Maintenance within the limited scope of the timing advance accuracy and scope. Timing advance alone is not providing enough indications to do localization services. Each cell of a LTE network needs to have a physical cell ID (PCI) assigned. The PCI is reported as part of the synchronization signal. Network Administration


As the range of the PCIs is limited to 504 values and neither the neighbours of a cell, nor the neighbours of the neighbours shall have the same PCI value assigned, the value selection per cells needs to consider its environment. This feature includes the automatic assignment of PCI values to cell, the detection of possible collision and also the optimization of the PCI values.

LTE Local User Account Management

O&M Security

This Feature introduces a local user account management for the Flexi Multiradio BTS.

Planning Tools like NetAct Configurator and BTS Site Manager provide the Site Configuration File, the Radio plan and the Transmission plan for the Flexi Multiradio BTS. These plans are downloaded, stored and activated to single Flexi Multiradio BTS via NetAct or BTS Site Manager. In addition the dedicated modification of selected managed objects is supported as well as the management of states and features. The SW Management provided by NetAct services and BTS Site Manager consists of software management functionalities focused to the Flexi Multiradio BTS. Those functionalities are downloading SW builds, activating SW builds and uploading SW configurations. With Configuration NetAct several downloads and uploads may run in parallel for multiple Flexi Multiradio BTS. A SW build consists of several files. Also Management SW update for parts of the SW are handled as builds consisting of one or more files updating the impacted SW segments. When a SW build is downloaded it can be activated immediately, or later by a dedicated activation request. The SW configuration upload functionality may be used to keep NetAct back-up data base up-to-date. Alarms are reported to the management systems, including the cause of the service loss. The alarms themselves are supplemented with the alarm manual pages to describe the conditions in more details. The fault detection also leads if needed to automatic recovery Network Monitoring actions. The Flexi Multiradio BTS alarm system gathers alarm reports from the application software in the Flexi Multiradio BTS and and Maintenance reports them to the NetAct. On NetAct a graphical user interface provides a view for active alarms and according reports as well as an alarm history and enables the operator to modify Alarm parameters. Alarm monitoring is as well possible with the BTS Site Manager. The Radio Network Performance Management provides the operators with continuous up-to-date information, enabling them to Network Monitoring maintain a high standard of network operability for their customers. With NetAct Threshold Based PM Alarming it makes it easier to and Maintenance detect faults, identify bottlenecks and optimize the network. Flexible KPIs provide a quick view about the actual network performance. Configuration Management

The Flexi Multiradio BTS Certificate Management feature provides the handling of the private and public key as well as digital certificates in X.509v3 format. Keys and certificates are used for mutual authentication between IPsec and/or TLS protocol peers. This feature represents the BTS local/peer part of the NSN Identity Management System (IDM) respectively a 3rd party PKI solution This feature enables centralized user account management for the Flexi Multiradio BTS and integrated Operation and Mediation function from NetAct together with the Remote User Information Management application (RUIM) application. It provides also a mass updating function of local user passwords for BTS.

ANR Fully UE based


In case an unknown physical cell ID (PCI) is detected and reported by a UE to the Flexi Multiradio BTS the corresponding EUTRAN Cell Global ID (ECGI) is derived with the help of the UE-measurements. The Flexi Multiradio BTS resolves the corresponding public IP address of the new found neighbor Flexi Multiradio BTS and establishes the X2 connection to exchange neighbor cell information respectively opens the X2 interface for control layer applications. The automated planning of neighbor relation to UTRAN cells is done on NMS level with the help of NetAct Configurator and Optimizer. This feature prepares neighbour relations for each LTE cell in the optimization scope and UTRAN automatically based on current LTE and legacy UTRAN network configuration data with an intelligent algorithm in Optimizer to identify possible UTRAN neighbor cells. This functionality can be triggered manually. From creation time onwards the established relations are updated/synchronized automatically in case of changes occurring at the UTRAN side (deletion of cell or change of the parameters), ensuring up-to-date Inter RAT neighbor relationships.

LTE830

LTE Automatic Lock

Uplink peak data rates are limited by the lack of support of 64QAM in UEs cat 1-4. 3GPP 36.213 defines MCS20 as highest coding Coverage, capacity scheme applicable to 16QAM. The usage MCS21 to MCS24 for 16QAM operation provides approximately 25% higher UL peak rates ad and peak rates allows to meet LTE 25.913 high level requirement of 50 Mbps in UL. In LTE as in other technologies the "lock/unlock" commands are necessary for specific objects so that changes to related parameters can be applied. This means that the lock command, the required parameter change and the unlock command need to be executed. As in LTE currently parameter changes are possible only via configuration data downloads, three different configuration files would be required. Configuration Management

With the help of this feature the operator does not have to care about the required lock/unlock commands, but only about the required parameter change. The required "lock/unlock" commands are issued automatically in Flexi Multiradio BTS. The operator can choose to use a less service impacting way by applying the graceful cell shutdown or the hard, but fast and immediate lock in case of cell parameter changes. After the parameter changes are done, the cell will be re-activated to that state it had before the modification.
