Charging analysis

Sukhbir Singh SDE (AXE-10)II

Objective

After the end of the lecture the trainees will be

able to :-

1. Describe the various variants used for charging in

2. Describe the whole sequence required for charginganalysis .

3. Define/Modify the charging analysis Tables .

# THE CALENDER FUNCTION :

- Controlled by a Real Time Clock (RTC) that ishandled by the operating system of APZ thatincrements the clock.

- The Calender Function in APZ controls Time

differentiated charging by means of the Real TimeClock.

- Clock is used by the functions :

Charging (Time differentiated charging)

Routine Test

Traffic Recording

-Information about clock can be printed by command :

<CACLP;

CALENDER CLOCK PRINT

TIME CLOCK TYPE RTU STATE

REAL TIME CLOCK NOT CONNECTED

DATE TIME DAY DCAT

020510 143845 FRI 0

Over a longer period of time, clock can start “Loosing” or

“Gaining”. This fact makes necessary to check and if

required, to adjust the clock at regular intervals.

However, the adjustment should not be more than a few

seconds over a time period of several months Clock

adjustment can be done by command:

CACLC:TDSF=5;

CACLC:TDSF=5,DATE=020510,TIME=0000;

CLOCK ADJUSTMENT

The day categories (DCAT) are set according to the

requirement of the administration at the time of installation of

the exchange. Calender information can be printed bycommand CACAP.

- Day categories for a particular date being holiday

can be set by command :

- CACAS : DATE=020510,DCAT=2;

- For removal of day categories from the list, command

CACAR is used.

DAY CATEGORIES

There can 10 DCAT be defined in the system .

DCAT- 0 : Ordinary working day

DCAT- 1 : Day before holiday (e.g. Saturday)

DCAT- 2 : Holiday

DCAT- 3 to 9 : Spare

CHARGING FUNCTION :

- Handled by the Charging Subsystem

(CHS) in the APZ. It comprises of :

Pulse Metering (PM)

Charging Methods

Toll Ticketing (TT)

CHARGING CONCEPT:

Differential Charging Concept Network Charging Concept

Differential Charging Concept

- The charging is based upon.

Distances involved

Class of subscribers and type of service

Type of day – Normal or holiday

Time of the day

Charging Analysis – The Charging Case (CC)

- CHS consists of software only.

- For flexibility in the charging analysis, all data is stored

in tables which can be printed , modified by means of commands.

CHARGING ANALYSIS :

- It is accomplished by means of several tables that deliver different analysis results.

- In the charging analysis, following things are analysed :

Who pays ?

Type of charging

Tariff to be applied for the particular call

Changing of tariff depending on type of day and time of day

Where the charging is to take place?

- Input to the Charging Analysis is the “Charging Case

- (CC)” – one of the result from B- Number Analysis table.

SPECIFICATION OF DATA FOR CHARGING ANALYSIS :

- Data specification for the Charging Analysis comprises of

following steps :

(1) Specification of Tariff (T) Data

(2) Specification of Switching Class (SWC) Data

(3) Specification of Tariff Class (TC) Data

(4) Specification of Charging Program (CHP) Data

(5) Specification of Charging Case (CC) Data

(1) Specification of Tariff (T) Data

- The Tariff Data table can be printed by using command

<CHTSP:T=ALL; TARIFF DATA

T TDS NSP 1 0 2 1 3 180 2 4 1 1 5 1.200 1 6 1.600 1

- The tariffs can be specified in the range 0.01 to

3276 seconds

- The tariff specification is done in the OP area

itself by using command CHTSI :

e.g. CHTSI :T= 24, NSP=1, TDS=90;

(2) Specification of Switching Class (SWC)

Data :

-The Switching Class (SWC) is like a time table and there can

be up to 16 different time tables (SWCs) in the exchange for

time differentiated charging.

- The SWC Analysis table is divided into an Operating (OP) and

Non-operating (NOP) area in order to make it possible tochange the data during traffic handling.

- The Switching Class data table can be printed byusing command :

<CHSSP:SWC=ALL;

SWITCHING CLASS DATA OPERATING

SWC DCAT TIME 1 0 0800 1400 2000

1 0800 1400 2 3 4 5 6 7 8 9

2 0 0730 2200 1 0730 2200 2 3 4 5 6 7 8 9 0730 2200

3 0 0600 0700 0800 1900

1 0600 0700 2030 2300 2 3 4 5 6 7 8 9

- Specification of SWC data (e.g. SWC=1) isaccomplished in the following steps :

CHSZI: SWC=1; (Clearing of NOP)

CHSPI:SWC=1; (Procedure initiation)

CHSSI:DCAT=0,TIME=0800&1400&2000;(Data specification)

CHSSI:DCAT=1, TIME=0800&1400;

CHSSI:DCAT=2&&9 ; CHSPE; (Procedure end)

CHSAI:SWC=1; (Transfer of data to OP)

CHSAR; (Reversion to old data)

DCAT=0 DCAT=0 DCAT=0

T=5T=6

An example of a tariff switching.

(3) Specification of Tariff Class (TC) Data :

- In the Tariff Class (TC), the tariffs used during the dayare specified.

- The Tariff Class (TC) data table can be printed by usingcommand :

<CHCSP:TC=ALL; TARIFF CLASS DATA

OPERATING TC SWC CPT DCAT T 1 PPC 1

4 1 PPC 0 6 5 4

2 3 4 5 6 7 8 9 4

- There can be up to 256 Tariff Classes in the exchange.

- When specifying a Tariff Class without any time

differentiated charging, no procedure has to be used as

one command is enough. E.g.

CHCSI:TC=1,T=1;

(Defining without swc)

- However, if a Switching Class (SWC) is used in the

Tariff Class (TC), a procedure has to be used as under :

CHCZI:TC=4; (Clearing of NOP)

CHCPI:TC=4,SWC=1; (Procedure initiation)

CHCSI:DCAT=0,T=6&5&4; (Data specification)

CHCSI:DCAT=1,T=6&5;

CHCSI:DCAT=2&&9, T=4;

CHCPE; (Procedure end)

CHCAI:TC=12; (Transfer of data to OP)

CHCAR; (Reversion to old data)

(4)Specification of Charging Program (CHP) Data

- The Charging Program (CHP) contains information

about the :

Tariff Class (TC) Method of charging – PM or TT or both

Charging Determination Code (CD)

A- party charging or B- party charging

Call Meter Alternative (CMA) etc.

- CHP can be from 1 to 4095

- Charging Determination Code (CD) can have

following values :

CD= 0 Superior exchange is CP and CDP. Pulses

may be registered in own exchange.

CD=1 Reception of Tariff Messages

CD=2,3 Own exchange is CP & CDP

CD=4 Subordinate exchange is CP & CDP

CD=5 Own exchange is CDP and

subordinate exchange is CP

- Charged Party (CP) may be :

AP= A Party Charging

BP= B Party Charging

NP= No Party Charging

- Charging Methods (CHM) can be :

PM= Pulse Metering

TT= Toll Ticketing

TTD= Combination of both PM & TT

<CIPSP:CHP=ALL;

- Specification of Charging Program data is accomplished in

following steps :

CIPZI:CHP=3;

CIPSI:CHP=3,TTD,AP,TC=2,CD=3,CMA=1&SMP-OFF;

CIPAI:CHP=3;

5) Specification of Charging Case (CC) Data

- The Charging Case (CC) is the input to the CHS from TCS. - The Charging Case (CC) data can be printed by command :

<CIBSP:CC=ALL;

CHARGING CASE DATA OPERATINGCC BC CHP 1 1

4 CO-0&&-1&-66 CL-0&&-4&-6&& -15 4

-Specification of Charging Case data may be :

(i) With branching condition

(ii) Without branching condition

- Branching conditions may be :

VPN=vpn Virtual Private Network

PTNCZ=ptncz Private Telecom Network Charging Zone

BGCZ=bgcz Business Group Charging Zone

CO=co Origin for charging

ACO=aco Origin for charging from A- No. Analysis

CL=cl Type of A – Subscriber

- For a Charging Case (CC) without any branching, no

procedure has to be used as all the data can be specified in one

single command. E.g.

CHASI:CC=4,CHP=2;

- However for a Charging Case with branching condition, a

procedure has to be used as under :

CIBZI:CC=ALL; (Clearing of NOP)

CIBPI:CC=112; (Procedure initiation) CIBSI:BC=VPN-

0&CO-0,CHP=2003; (Data specification)

CIBSI:BC=VPN-0&CO-1,CHP=3;

CIBSI:BC=VPN-2&PTNCZ-2&CO-1,CHP=200;

CIBPE:CC=112; (Procedure end)

CIBAI:CC=ALL; (Transfer of data to OP)
