Overview of BCF software handling

2 Overview of BCF software handlingThe base station system (BSS) consists of base transceiver station (BTS) sites and at

least one BSC. A BTS site can be considered as the O&M functionality of a physical BTS

site.

A base transceiver station is referred to as a sector of the base station in radio network

maintenance. A sectorised BTS site can, therefore, consist of several logical BTSs. Both

types of the BTS (sectorised and unsectorised) are covered by one BCF. In Nokia

Siemens Networks's implementation of the BSS, a BTS site can consist of several

logical BTSs. One entity takes care of all the common functions of the BTSs on one BTS

site. This entity is called a base control function (BCF), which can be seen as the

common brain of several BTSs. Its main tasks are base station operation and mainte-

nance functions, that is, software loading, unit configuration, and alarm handling. The

BCF communicates with the BSC via the Abis O&M interface. The term BCF is used

here for the functional entity that offers the O&M functions of the BTS network element.

BCF software is handled in software builds, which are combinations of software entities

that provide the defined hardware with the functions required for it. The builds are

referred to as BCF software builds. A BCF software build includes the software of the

whole base station site. In the case of Flexi Multiradio BTS, Radio Module's software in

BTS can be shared with 3G or LTE

One of the advantages of a computer controlled network element is that new telecom-

munications functionalities can be introduced into existing network elements by replac-

ing and modifying the software. In the BSC, new BCF software is handled in software

builds. Software is loaded to the BCF when new BCF software is released, when a new

BTS site is brought into use, or when the BCF is restarted.

2.1 BCF Software Handling (command group EW)

BCF software is handled in the BSC with the commands of the commands group EW

(BCF Software Handling MML).

With the EW commands you can create and delete BCF software builds on the BSC'sdisk. You can attach the created software to a desired status in the BCF and to detach

the attached software build. A software build that is attached to the BCF can be acti-

vated. You can also change the statuses of two software builds with the status NEW,

BACKUP or FALLBACK, so that the attachment of the first status will change to the

second status and vice versa. You can set an initial build for and remove it from a BTS

site type. In addition, there are output commands that list information on the software

builds created in the BSC, the contents of the software build, and the software configu-

ration of the BCFs. You can also list ongoing build management operations. A more

thorough introduction of the EW commands is given in the following sections. Those

sections also give important information that should be taken into consideration when

using the commands. Figures are used to illustrate how the main commands of the EW

command group function.

BCF Software Handling Overview of BCF software handling

Id:0900d8058077eaef

The most central BCF software handling actions are transferring the software build to

the BSC's disks and bringing the software build into use in the BCFs. Software is brought

into use by creating a new software build, attaching it to the desired status in the BCF

and activating the software build. When the new software build is stable, its status is

changed to BACKUP. After this the old software build can be detached from the BCF

and deleted from the software management file and from the BSC's disks.

All BCF software handling functions discussed here can be done by using local MML

commands at the BSC site or with remote MML commands from the NetAct. A new BCF

software build can be transferred into the BSC on a floppy disk on site or through the

operation and maintenance network by means of file transfer services.

Figure 1 Transferring a BCF software build

Transferring software from the NetAct is practical for mass downloads. During a down-

load, software is transferred from a higher level network element to a lower level networkelement. The transfer is carried out file by file so that the master file and all application


10/36

10 DN98633622

Issue 8-2


Id:0900d8058077eaef


files of the software are transferred. Downloading and activation can be timed so that

the system can carry out the operation when the BCFs have the least amount of traffic.

With the NetAct applications you can also have all the software builds in one controlled

place.

2.2 Creation of BCF software build

With the EWC command you create a new BCF software build into the BCF Software

Build Management File (BTMFIL).

Figure 2 Creating a BCF software build

The creation operation reads the master file and checks that all the application files

specified in the master file are in the same subdirectory. A master file contains informa-

tion on all the application files of the software build, together with their version data. A

software build is also accompanied by a master file and the master file is located in the

same subdirectory as the software build. An application file is a load unit that contains

the code and standard data of one software module, or one file block. The application

files are the smallest parts of a software build that can be separately introduced into the

BSC.

The creation operation also checks that the versions of the application files are the same

as specified in the master file. The BSC also checks that the sizes of all build files are

the same that are mentioned in the master file.

The build ID is the identity string that is used for identifying unambiguously the different

BCF software builds on the BSC's disk. The same build ID can be used in different BSCs

at the same time.

The build type is determined during creation. The BSC checks the file format of themaster file and decides the type of the build. The alternatives are DF, C, I, P, CX, E, XM,

XE, XB and M.

2.3 Software build attachment to BCF

With the EWA command you attach the software build to the desired status in the BCF

specified in the command. The BCF builds in the BSC can be attached to the BCF with

three different statuses. A build status is the activity status of a software build that is

located on a disk and is created with management commands. When the software build

is attached to the BCF, it has an activity state known as its status.

These statuses are NEW (NW), BACKUP (BU) and FALLBACK (FB).

Build type Description

DF The software build used in the Talk-family base sta-

tions.

C The software build used in the MetroSite base stations.

I The software build used in the InSite base stations.

P The software build used in the UltraSite base stations.

CX The software build used in the MetroSite and UltraSitebase stations.

E The software build used in the FlexiEDGE base sta-

tions.

XM The software build used in the BTSplus Mainline base

stations.

XE The software build used in the BTSplus eMicro base

stations.

XB The software build used in the BTSplus Basic base

stations.

M The software build used in the Flexi Multiradio base

stations.

Table 1 Software build types

Status Status description

New (NW) NEW is the status of a new software build when it is

first introduced in the BCF, after which it will be brought

into use.

Backup (BU) BACKUP is the status of a software build that is usually

defined as active and in use, and is therefore normally

loaded during initial loading when the BCF is restarted.

The BACKUP build cannot be removed with the BCF

build management commands.

Figure 3 Attaching a BCF software build

The system automatically checks that the site type and the build type are compatible.

The attachment operation then reads the master file and checks that all the application

files specified in the master file are in the same subdirectory. It also checks that theversions of the application files are the same as specified in the master file. The BSC

also checks that the sizes of all build files are the same that are mentioned in the master

file.

If possible, the attachment operation downloads the software build to the BCF as a back-

ground operation without disturbing ongoing calls, and stores it to the BCF's non-volatile

memory by replacing the oldest build in that memory. The BCF's memory consists partly

of a non-volatile memory, which is not erased if the power supplies fail. It is possible to

save information into the non-volatile memory by a program. The BCF hardware

database and the BCF's software have been saved into the non-volatile memory. The

non-volatile memory is often called a FLASH memory.

The BCF software management system checks the load rate of the BCSU beforestarting the background downloading of the software build. If the load rate is high

Fallback (FB) FALL-BACK is the status of a software build that is

usually older than the BACKUP build, and which

usually functions as the online backup copy of the BCFsoftware build. If necessary, the FALL-BACK build can

be loaded to the BCF with the MML commands.

enough to possibly prevent the call setup, the downloading will be put in a queue until

the load rate decreases enough and the downloading can be started.

You can check the state of the download operation with the EWI command.

You can also monitor various phases of BCF operations on the display of the serviceterminal with the BCF Reset Phase Monitoring service terminal extension. For more

information, see BCF Reset Phase Monitoring.

2.4 Activation of BCF software build

With the EWV command you activate the attached software build and restart the BCF

with it. If necessary, the build will be loaded from the BSC's disks to the BCF.

Figure 4 Activating a BCF software build

The BCF builds in the BSC can be attached to the BCF with three different statuses.

These statuses are NEW (NW), BACKUP (BU) and FALLBACK (FB). Refer to table

Software build statuses for a description of the statuses. Each of these builds can be

activated.

The activation command changes the default build of the BCF and it stays as the default

until another build is activated. The default build is the build that is primarily used for the

initial loading of the BCF and must have the status BU, NW, or FALLBACK. Initial

loading is the loading of the computer unit's or system's load modules from disk or from

the non-volatile memory into the random access memory (RAM) for execution. There

can only be one default build at a time. Build activation normally causes a BCF restart

with the activated software. There are some cases where the BCF restart does not

begin, but the activated build is only set as a default build. These are:

• the administrative state of the BCF is LOCKED

• the O&M link of the BCF is out of order

• the BCF does not respond to the reset request sent by the BSC

The activation command is rejected by the system if the software attachment procedureis still in progress. In that case the activated build is not changed to the default build and

the activation command must be given again later.

The BCF restart initiates the loading of the software build from the BSC to the BCF if the

build is not found in the BCF's non-volatile memory.

2.5 Status change of two BCF software builds

With the EWH command you change the statuses of two software builds. If the other

status is empty, the attached status will be copied to the empty one, but the empty status

cannot be copied to the attached status.

Figure 6 Changing NW and BU statuses

If either one of the builds is the default build, it remains as the default after the status

has been changed.

If one status is BU and empty, and the default build has the other (NW) status, the

change command copies the NW build to the BU status and changes the build with the

BU status into the default build.

2.6 Detachment of software build from BCF

You cannot delete a BCF software build that still has attachments. You cannot delete aBCF software build that has been set as the initial build.

2.8 Setting of initial software build

When you have created a software build, you can define an initial software build in

advance for each BTS site type with the EWS command.

When a BCF is created, this predefined software build is attached and activated auto-

matically to the new BCF. The initial builds are indicated with the following letters:

The build is attached to the BU status. If the O&M link of the BCF is already in the

working state, the system also background downloads the software build into the BCF.

You may thus ignore two standard manual work phases, attaching and activating, in

BTS commissioning.

You can also remove or change the initial build with the EWS command at any time. You

can see the initial BCF software builds with the EWL command.

2.9 Information listingWith the EWI command you can output ongoing BCF software handling system activities

like background downloading or saving software to the BCF's non-volatile memory. The

command also shows operations in the pending state.

You can output all the created software builds on the BSC's disks with the EWL

command. The command shows the following information on each created software

build:

• build ID

• build type

• release version

• initial build of the BTS site type

• master file name

• subdirectory

• connection counter

The connection counter tells how many attachments have been made to the software

build.

You can output the software configuration of the BCF with the EWO command. The

command shows the following information on all attached software builds of the BCF:

• status

• build ID

• release version • subdirectory

• state (“DEFAULT” in this field indicates the default build)

• software master

• in the case of Flexi Multiradio BTS, if the Radio Module is shared and the software

master is WCDMA, then also the file name and the version of the active software in

Radio Module are shown.

You can output build and file information on the application files included in the software

build with the EWP command. The command shows the following information on the BCF

software build:

• build ID

• build type

XB The initial build of the BTSplus Basic base stations.

M The initial build of the Flexi Multiradio base stations.

• master file name

• master file version

• subdirectoryIn addition, it also shows the following information on the files of the software build: appli-

cation file names, file versions, freezing dates, file types, and unit information which indi-

cates the units in which these files will be run.

2.10 Capacity

The BSC manages BCF software in builds. In the BSC's disks there are 40 subdirecto-

ries for BCF software, each containing one build.

The BCF software builds are located in various disk directories and each software build

is located in its own subdirectory. For more information on the directory structure, refer

to figure BSC directory tree in BCF Hardware Database Handling .

The capacity of the BCF software management files limits the number of BCF software

builds that can be created in one BSC. The BSDATA (BSS Radio Network Configuration

Database) limits the number of the BCFs that can be created in one BSC. The capacity

of the management files is the following:

• the maximum number of BCFs created in a BSC depends on the BSC configuration

(see Product Descriptions Product Description of Base Station Controller BSC2i,

BSCi and Product Description of Base Station Controller BSC3i ).

• the maximum number of software builds created in a BSC is 40

• the possible status of a BCF software build attached to a BCF is NEW (NW),

BACKUP (BU), or FALL-BACK (FB). At any one time there can be only one command managing BCF software handling in

the BSC, but one command can handle several BCFs at the same time.

The maximum number of simultaneous download operations has been restricted to 32.

If there are no resources left, the BSC puts the extra downloading operations in a queue

until resources are available again. It is possible to load the same build to every BCF or

a different one to each BCF.

2.11 Handling firmware build in BTSplus BCF

In the BTSplus BCF, firmware (FW) build is handled in the BSC with the commands of

the command group EW (BCF Software Handling MML). With the EW command, youcan create firmware build to its own BCF SW management file. You can attach the

firmware build to BTSplus BCFwith the NEW status.

After attaching, BSC starts the background download for the firmware build if O&M link

is in order. BTSplus automatically upgrades firmware build within BTS after background

download. When the firmware build is up and running in BTSplus, detach firmware build

from the BCF with the EW command that the NEW status can be released for the BCF

software build management.

Attach a valid software build with NEW status to BTSplus after firmware build download

so that the software build overwrites the firmware build in the non-volatile memory in

BTSplus. This software build should be the same one which is already running in

BCFand attached in the BACKUP status. After software build background download,

BCF Software Handling Bringing a new BCF software build into use

Id:0900d80580790704

3 Bringing a new BCF software build into useBringing the BCF software build into use can be separated into the phases listed below

as links. The procedures in that list are to carry out in the presented order.

BCF software handling functions discussed in the following sections can also be per-

formed from the NetAct.

Before you start

The following initial conditions should be met before you start to bring a new BCF

software build into use:

• the BSC's OMU is in the normal working state (WO-EX) (the USI command)

• both of the BSC's disks are in the normal working state (WO-BU) (the ISI

command)

The new BCF software build should be tested with one BCF. When its stability has been

proven to be good, the software build can be distributed to the other BCFs.

3.1 Transferring a BCF software build

Before you start

The BCF software builds are located in the subdirectories on the BSC's disks. On the

disk there is a directory named BCF_PACK and subdirectories named PACK_X. The

value of X ranges from 0 to 39. Ensure that the new BCF software build is located on a

floppy disk (the IWX command). Copy the BCF software build files to the first unused

build subdirectory of both disks, for example from a floppy disk.

Steps

Output the existing software builds and their subdirectories (EWL).

With this command you search the first subdirectory that does not include any created

software builds.

ZEWL;

The command has no parameters.

2 Check that the subdirectory is empty on both disks (IWX).

ZIWX::,::,;

3

Delete the extra files from the subdirectory (IWD).

You can delete the extra files from the subdirectory if the subdirectory is not empty but

it contains no files that associated with the created software builds.

ZIWD::,::,,,;

4 Define the source of the software build on the floppy disk (IWY).

The alarm 7715 is set if the O&M unit of the BCF is caught in a circle of resets. The BCF

or has received at least 3 resets within 30 minutes. When this alarm is set, the BCF is

unable to operate properly.

You must find out the reason why the BCF is receiving continuous resets and correct

the error that causes them. Possible reasons for the error can be, for example, a wrong

hardware database in the BCF, a hardware fault in the BTS, a change of the O&M link

state during the reset, or a corrupted BCF software build.

The system cancels the alarm when 15 minutes have passed after the last reset of the

BCF.

3.6 Detaching a BCF software build from the BCF

Steps

Check the BCF software build (EWO).

ZEWO:;

Check that the BCF has a software build that has been attached to the required status

and that it is not the default build or the BU build.

2 Detach the software build from the BCF (EWE).

ZEWE::;

3

Check the command printout.If the system outputs an error code, check it in General Error Messages of System, find

out the reason for it, correct the fault, and try again.

3.7 Deleting a BCF software build

Before you start

The BCF software build files cannot be deleted from the subdirectory where the files for

the created builds are located.

Steps

Check if the software build has any attachments (EWL).

Note also the subdirectory name where the build files are located. If the build has been

attached to the BCF, it must be detached before it can be deleted.ZEWL;


2

Delete the software build using the parameter value DSK (EWD).

ZEWD::;

Further information

If the command execution failed, check the error code from General Error Messages of

System, correct the situation and try again.

Example: Deleting the software build

ZEWD:EP_1_0:DSK;

If you have problems with deleting the physical software build files with the EWD

command, you have to delete them with the commands of the I/O system. See Disk File

and Directory Handling (command group IW).

The BCF software build files must not be deleted from the subdirectory where the files

for the created builds are located (IWD command).

For an overview, see Overview of BCF software handling.
