1.3 Basic Concept/GlossaryThis chapter describes the basic concepts used in this document.

Nastar SystemThe Nastar system consists of multiple physical entities such as the Nastar server, eSAU, SAU,LTE SAU, and PS SAU.

Basic DataBasic data includes configuration data, engineering parameters, map files, and other data suchas NE group information, terminal information, VIP information, complaining subscriberinformation, feature matrix, and mailbox information.

Analysis DataAnalysis data includes the MR data, CHR data, and GSM performance data.



7

MR DataMR data file: It is generated in the unit of measurement objects based on the measurement thatis triggered periodically or by specific events. It records network environment features such asserving cell RSCP, serving cell Ec/No, DL BLER, neighboring cell RSCP and neighboring cellEc/No for a certain place at a certain time during a call.The MR data is recorded in the unit of measurement objects for a certain place at a certain time.Therefore, a large amount of collected MR data can effectively show the network trafficdistribution, signal coverage, and other network indicators. In this way, the Nastar can performnetwork performance analysis from the network perspective.The MR data is generated by the base station controller and saved as a binary file on the SAUboard (or the OMU board if there is no SAU board).

CHR DataCHR data file: It records key information such as access and release time, access and releasecell, and access and release cause in the unit of calls.The CHR data is recorded in the unit of calls. Therefore, the CHR data effectively shows thesubscriber behavior on the network and enable the Nastar to perform network performanceanalysis from the subscriber perspective.The CHR data is generated by the base station controller and saved as a binary file on the SAUboard (or the OMU board if there is no SAU board).

Basic subscriptionBasic data subscription is used to turn on the NE data switches on the live network so that NEscan generate raw data and to enable the data preprocessing functions of the SAU and eSAU sothat the raw data generated by NEs can be preprocessed to the analysis data that meets the Nastarrequirements.

Application subscriptionApplication data subscription is used to deliver specific rule files to NEs so that NEs can generateraw data that meets requirements.

OSSOSS refers to the Operating Support System. On the GSM, UMTS, or LTE network, the M2000is used.

IMSIIMSI refers to the international mobile subscriber identity. An IMSI is a 15-digit string consistingof digits 0 to 9. The structure of the IMSI from left to right is MCC+MNC+MSIN. MNC andMSIN form the NMSI.l MCC refers to the mobile country code of a mobile subscriber.l MNC refers to the mobile network code, that is, the PLMN code of a mobile subscriber.

PLMN refers to the public land mobile network.



8

l MSIN refers to the mobile subscriber identification number.l NMSI refers to the national mobile subscriber identification and uniquely identifies an MS

in a country.Huawei provides a dedicated solution to secure IMSI information. When the anonymous policyis enabled on the network where the Nastar is deployed, first encrypt IMSIs using the anonymouspolicy tool. The Nastar analyzes services based on the encrypted IMSIs.

IMEI-TACInternational Mobile Equipment Identity (IMEI) uniquely identifies an MS.An IMEI consists of 15 digits ranging from 0 to 9 and is composed of the following four parts:l Type approval code (TAC): consists of six digits and is used to identify an MS type.l Final assembly code (FAC): consists of two digits and is used to identify a vendor.l Serial Number (SNR): consists of six digits and is used to uniquely identify an MS when

the TAC and FAC of two MSs are the same.l SSP: a spare bit, which consists of only one digit and is reserved for use.In an IMEI, the first eight digits that are composed of TAC and FAC uniquely identify an MStype, and the later digits from 9 to 15 uniquely identify an MS of a certain type.The Nastar analyzes only MSs of a certain type identified by the first eight digits that arecomposed of TAC and FAC. In the Nastar window, IMEI-TAC refers to these eight digits.

Peer NumberPeer number refers to the phone number of the peer end during a call, such as the fixed-linephone number or mobile number. For example, if the calling party is being analyzed, the peerend number is the phone number of the called party.Huawei provides a dedicated solution to secure MSISDN information. When the anonymouspolicy is enabled on the network where the Nastar is deployed, first encrypt MSISDNs usingthe anonymous policy tool. The Nastar analyzes services based on the encrypted MSISDNs.

LayersLayers are classified into site layers, service layers and map layers.l Map layers are generated when the map files are imported, such as street map layer and

river map layer.l Site layers are generated when the engineering parameter files are imported, such as base

station layer.l Service layers refer to the layers with counters or grids in the network geographical

observation function.

BHCABHCA refers to busy hour call attempts, that is, the number of calls within one busiest hour.The formula for calculating BHCA is as follows: BHCA = A x W1 + B x W2 + C x W3.Table 1-2 describes the definition of each counter in the formula.



9

Table 1-2 Definitions of A, B, C, W1, W2, and W3Counter DefinitionA Total number of services under a base station controller in busy hours.

The services include calls and data services.B Number of handovers triggered during busy-hour services.C Number of NAS messages in busy hours.W1 Weight of services affecting BHCA.

l The value is 1 for GSM.l The value is 1 for UMTS.l The value is 1 for LTE.

W2 Weight of handovers affecting BHCA.l The value is 0.3125 for GSM.l The value is 0.33 for UMTS.l The value is 0.33 for LTE.

W3 Weight of NAS messages affecting processing capabilities.l The value is 0.41 for GSM.l The value is 0.38 for UMTS.l The value is 0.38 for LTE.

This counter can reflect influences on the performance of the Nastar and SAU of a user's networkin different traffic models. This helps to check whether the Nastar and SAU can process datafor a specific network scale and traffic model. Traffic model changes cause BHCA changes.Users need to expand the capacity if the processing capability of the Nastar fails to meet BHCArequirements.

Equivalent NEEquivalent NE is a term introduced to calculate the network scale for the Nastar. Table 1-3describes the relationship between equivalent NEs and the network scale on the Nastar side.
