Nokia 4G LTE Baseband Dimensioning


Target of Baseband Dimensioning:
Target of Baseband Dimensioning: Allow to estimate HOW many sites are required taking into account the HW (System Module) Limitations
The approach presented so far in this chapter to calculate the number of sites from the capacity point of view (site throughput) only takes into account Physical Layer and/or RRM features into account (e.g. Channel bandwidth, transmit power, scheduler type, etc...)
System Module options:
FSMF: high capacity system module
FSME: high capacity system module
FSMD: lower capacity system module
Input of the dimensioning:
Total Number of subscribers
Number of active subscribers (per Site)
Share of active subscribers
Output of the dimensioning:
Number of sites from baseband point of view

Radio Resource Control (RRC)

The Radio Resource Control (RRC) protocol is used in UMTS and LTE on the Air interface. It is layer that exists between UE and eNB and exists at the IP level. This protocol is specified by 3GPP in TS 25.331[1] for UMTS and in TS 36.331 [2] for LTE. RRC messages are transported via the PDCP-Protocol.

The major functions of the RRC protocol include connection establishment and release functions, broadcast of system information, radio bearer establishment,reconfiguration and release, RRC connection mobility procedures, paging notification and release and outer loop power control.[3] By means of the signalling functions the RRC configures the user and control planes according to the network status and allows for Radio Resource Management strategies to be implemented.[4]

The operation of the RRC is guided by a state machine which defines certain specific states that a UE may be present in. The different states in this state machine have different amounts of radio resources associated with them and these are the resources that the UE may use when it is present in a given specific state.[4][5] Since different amounts of resources are available at different states the quality of the service that the user experiences and the energy consumption of the UE are influenced by this state machine.[5]

Video Tutorial Mentum Cell Planner


The below activities are examples of how to plan a GSM network with Mentum CellPlanner. the information required to plan the network, the main activities and some results to obtain.

Prerequisites
need the following information to create a GSM network plan in Mentum CellPlanner:
• Map data as input to analysis functions.
• RF measurements as input to optimized propagation models.
• Site data such as coordinates, location areas, registration areas, neighbor relations and antenna configuration.
• Traffic load estimates for GSM services to support in the network

Hunter NePa (Network Parser) - Huawei 4G XML (eNodeB) Format

Step by step to download Huawei 4G Configuration Parameters: (XML)

    Log in into “iManager M2000”.
    Access Menu: 'NE File' > 'NE Backup'
    On the left, select the NE you want to backup.
    Click in 'Backup' button
    In the 'NE Backup list' filter 'Backup File'. Set 'Begins with' 'BAKDATA'. This will make sure you'll download the NE you just backed up (The files that begins with AUTOBAKDATA are created by the system using backup schedule)
    Download the configuration file from M2000 to your computer by selecting it in the 'Download to OSS Client...'

Step by step to parse (process/extract) Huawei 4G Configuration Parameters: (XML)

    First, check if the downloaded files are compressed (ZIP, RAR, 7-z, GZ, etc...). If so, uncompress it using any Compress/Uncompress utility such as Winzip, Winrar or 7-zip.
    Then, run the correspondent Hunter Macro (to parse the desired format). Note that you must use an exclusive/specific macro for each type of Vendor/Technology.
    Optional: Click 'Edit' button (a pencil) in the Hunter Nepa Main Menu, to indicate where the raw files are.
    Optional: Click 'Open Folder' button in the Hunter Nepa Main Menu, to check (open) the target folder and verify if it only contain the intended files (raw, extracted). If this folder contains other files, the macro may have some problems.
    Click 'Run' button (Exclamation Mark) to process.

WCDMA Radio Network Capacity Dimensioning Issue

WCDMA is a self-interference system
WCDMA system capacity is closely related to coverage
WCDMA network capacity has the “soft capacity” feature
The WCDMA network capacity restriction factors in the radio network part include the following:
Uplink interference
Downlink power
Downlink channel code resources (OVSF)
Channel element (CE)
IUB  Bandwidth
