3. PrePiad Card (PPC)

4. Introduction PPC service is Prepaid Calling Card Service where user buy s prepaid cards to make call The user, after purchasing a PPS card with a fixed face value, obtains the balance in the card. When he initiates a call with the card, the system accepts or rejects the call according to the card status, balance, and validity period. During a call, the system deducts the cost from the card in real time, namely, real-time charging. If the balance is used up, the call is terminated. This is the process of prepayment of the service. Its very convenient and popular service among both users and operators

5. Features Calling Number Black List –If wrong PIN inputs reach the specified threshold from the same calling number, the blacklist count will be accumulated. If the call from this calling number passes the authentication without reaching the threshold, the blacklist count will be cleared. When the blacklist count reaches its threshold, the calling number gets locked. In this condition the calling number cannot access the PPS service in period of time. –After entering the blacklist for a preset period, the calling number will automatically be cleared from the blacklist if calls are made from this calling number. Then the calling number can use PPS normally.

6. Features Originating Call Screening –This feature is used to permit or bar some regions or calling numbers to access the service. The screening number may be country code, area code or partial (or complete) calling number. –The screening type can be “ None ”, “ Restricted ” or “ Permitted ” : –“ None ” means this function is disabled. –“ Restricted ” means that the screening numbers are not allowed to call in. –“ Permitted ” means that only the screening numbers are allowed to call in.

7. Terminating Call Screening –This feature is used to screen the called number which is dialed by the user. The screened number may be country code, area code or specific calling number. Features

8. Balance Prompt After Called Party Hooks On –After a call ends, service can prompt the balance to the user if the called party hooks on first. Call Duration Prompt After Called Party Hooks On –After a call ends, the service can prompt duration of last call if the called party hooks on first. Call Cost Prompt After Called Party Hooks On –After a call ends, the service can prompt cost of last call if the called party hooks on first. Features

9. Language Selection –PPS service can provide up to 8 types of prompt language for the user to select. If user ’ s selection fails, service will use default prompt language. Before user makes the selection, service will play prompt message by all type prompt languages in turn. Features

10. Charge Discount Based on Account Number –In PPS service, each card has a ChargeRateModulator. And cards from different batch calling different called number from different country or area may have different discounts. If a card has one discount, the final ChargeRateModulator will be ChargeRateModulator * (1-discount).

11. Feature Recharge Bonus –A bonus is applied to user balance when he recharges his account –Depending on rules some bonus is added to the user account –Bonus rules are configurable by the operator

12. Feature Usage Bonus –This bonus is applied when subscribers usage exceeds a certain threshold set by the operator. –Here user recharges to the same card/account –This feature can stimulate the user to further use the service –The more you use, the more bonus you get –Principle of usage bonus can be % of amount used during a certain period

13. How it works User dials 1010 and enters the service flow for this service The service asks for the PIN number on the scratch card. IN verifies the PIN number and sends a signal to SSP to connect the call The call continues until the balance is consumed. At this time SCP instructs the SSP to disconnect the call.

14. Example If a user wants to dial 021-34558588 using calling card, he will dial 1010 and then upon prompt enter the PIN number. After entering the PIN, he can dial his desired number to make this call. After ending the call he may hand up or dial another number.

66. How it works This service works on the principle of forwarding the called number to a pre-configured number set by the subscriber of this service. Example follows

67. Example (Incoming) Malik has subscribed to UPT service. His number is 034838938. He gives this number to his friends. When his friends want to call him anytime, they will dial 034838938. If Malik has set incoming PIN then he first needs to enter his PIN. After successfully entering the PIN he can receive this call.

68. Example (Outgoing Call) Now Malik wants to use his UPT number to make an outgoing call. First he will dial the UPT access code. He will listen to the prompt to enter the PIN of his account. After successfully passing the PIN check, the system will check his balance to see if he has enough balance. Now the system will prompt him to dial the destination number.

69. Weather Report Sports Info Airline Info Exam Results Premium Rate Service

70. Introduction PRM is used for accessing info/content and recreational services In PTCL this service is 0900 service. The end user is charged with a premium rate for this information access Content provider and operator split revenue Subscribers of this service are content providers

71. Red List –All telephone subscribers on the red list can enjoy free-of-charge service and the bills for their calls are not charged. Blacklist –For subscribers who do not want to enjoy this service, you can put them onto the black list, so that the telephone subscribers on the black list will be refused to call this type of service. PRM Service Features

72. Call Forwarding on Busy/No Answer –When information console is on busy or no answer, the call can be transferred to the same type of information console. Information Valid Period –The valid period of information service can be set as required. For example, an information service can be provided from 10th to 12th March. Features

73. Integrated Service Window –The system provides information for subscribers to select, and connect to corresponding information service console according to the selections of subscribers. It is possible for multiple subscribers to use one PRM number to be their access code jointly. Features

74. –For example, two subscribers, one is entertainment information hotline, another is stock hotline, these two information providers share one PRM number. The end user dials the PRM number will get the announcement “ Welcome, please dial 1 to connect entertainment information hotline, dial 2 to connect stock hotline”. These announcement and choice is different from different subscribers. So service can define the announcement and the selection by using Integrated Service Window Function. Features

75. How Does it Work Call Connection Process –1. Subscriber dials information console number from telephone; –2. If subscriber is not directly connected to SSP, terminal office will send the call to the nearest SSP –3. SSP judges that this call is a PRM call and reports it to SCP –4. SCP checks this information console is valid or not.

76. –5. If this information console has no integrated service window, SCP will add route flag before the information console number and instructs SSP to select route to this information console. –6. If this information console has an integrated service window, SCP will instruct SSP to collect subscriber’s selections from the caller and report the collected information to SCP –7. SCP retrieves the information console number required by subscriber according to subscriber’s selections, and instructs SSP to connect subscriber to this information console. –8. SSP connects How Does it Work

77. Benefits Benefits for Operators: – Operator host content and charge a premium fee –Flexible and powerful charging methods for the premium charge Benefits for Subscriber: –One contact number and many information channels –Profit earning with less initial investment Benefit for Users: –Content services are accessible easily through normal DTMF phone –Only need to remember one number

78. Example For example a user wants to listen to flight schedule from PIA. The number is 0900-11786 He will dial 0900-11786 and will listen to the prompts by IN. Upon selecting his desired flight number and its related info he requires, he will be played the information

79. Number Portability

80. Introduction Number Portability is changing location but retaining the telephone number with in the operator. To use this service the subscriber, who is relocating to another city, applies for this service. Other people can reach him by calling his same old number.

81. Service Features Auto Connection – Automatic connection with the new number without informing the caller about the new number. – Automatic connection with the new number after the caller is informed about the new number by playing an announcement. Auto Connection must be enabled if the announcement function is disabled.

82. How it works To use this service the subscriber, who is relocating to another city, applies for this service. Other people can reach him by calling his same old number. His old number will be ported to new number according to the routing modes. Routing modes are described next.

83. Routing Modes 3 routing modes available –Onward mode –Query on release mode –All Call Query mode

84. NP Networks There are three types of network in the NP service: Originating Network: the network where the call is originated from Donor Network: the network to which the number range has been allocated Recipient Network: the network where a number is located after being ported

85. On-Ward Mode –When a user initiates a call, the exchanger routes the call to the exchanger of the network where the called locates in according to the called number. –The exchanger where the called locates in checks if the called number is an NP number, if yes, trigger the NP service.

86. Onward mode Caller Called 1 2 3 4 5 No additional requirement on exchanges Ideal for networks with NP ratio < 30%

87. –When a call is launched, the exchange routes the call to the exchange of the network where the called originally located. –The exchange where the called originally located in checks if the called number is an NP number, if yes, releases the call. –The exchange of the network where the calling party locates triggers the NP service according to the release code set by the exchange of the network where the called party locates Query on Release mode

88. Caller Called Donor Network has to send release codes Higher requirement on existing network

89. All Call Query mode –When a user initiates a call, the call will not be routed to the exchange of the network where the called located in. –All calls will trigger the NP service, the NP service checks if the called number is an NP number. –If the called number is an NP number, The exchange of the network where the calling party locates triggers the NP service. The NP service queries the new number according to the called number, and delivers the call connection

90. All Call Query mode All calls are forwarded to IN, thus increased traffic Volume, ideal for networks with NP ratio > 60 %

91. Example Mr. Jawad has subscribed for this service who moved from Lahore to Islamabad. His old number was 042-567899 His new number in Islamabad is 051-2823456. Now if his friends wants to reach him, they can still dial 042-567899 and reach him due to number portability service.

92. Free Phone / International Free Phone

93. Introduction FPH allows “reverse charging” where subscriber receives calls at his own expense Subscriber can posses multiple sets that can be accessed by a single number International Free phone ( introduced in IN expansion project) extends free phone service through out the world

94. Service Features TDR ( Time of the Day routing) –For example, the service subscriber can set to connect all the calls initiated during the period of 08:00 ~ 11:59 hours to the number 075526869880, connect all the calls made during the period of 12:00 ~ 18:59 hours to the number 075583371091 and release the calls in other time segments after an announcement is played.

95. Day of Year Routing (DOY) –For example, the service subscriber can set to connect all the calls initiated during the period from July 1,2003 to August 31, 2003 to the number 075526869880, connect all the calls made during the period from September 1, 2003 to December 31,2003 to the number 075583371091 and release the calls in other time segments after an announcement is played. Service Features

96. Day of Week Routing (DOW) –For example, the service subscriber can set to connect all the calls initiated during the period from Monday to Wednesday to the number 075526869880, connect all the calls made during the period from Thursday to Saturday to the number 075583371091 and release the calls in other time segments after an announcement is played. Service Features

97. Call Limit Simultaneous Call Limit This service feature realizes the function of limiting the number of the simultaneous calls to a terminal number or a forwarding number. When the limit is reached, the calls routed to the terminal number or forwarding number will not be connected, and an announcement will be played. –For example, a service subscriber has a hunt number 075582960321 and has two terminals in this hunt group. Now the service subscriber can set simultaneous call limit for the number 075582960321 as two. By doing this service subscriber can make sure that the hunt number 075582960321 handles only two calls simultaneously.

98. Call Cost and Time Limit –This service feature allows a service subscriber to define the maximum number of calls or the call cost within a window of time. Once the call count or the cost equals the call limit, any subsequent call received will not be serviced. This lessens the possibility of congestion at the service subscriber ’ s call handling equipment. The maximum number of calls and call cost limit can be defined on a daily or monthly basis. –For example, if the limit of daily call times is 100, and that of daily call cost is 500 USD, when the call times in a day reach 100 or the call cost in a day reaches 500 USD, the system will not connect the new calls for the subscriber ‘ s FPH service number. Call Limit

99. Configurable Maximum Single Call Duration –The service subscriber can set the maximum duration for each call in advance. If the maximum call duration is reached, the call will be released without any announcement played. –For example, if the maximum single call duration is set to 180 seconds for a service subscriber then, any call terminating on that service subscriber terminal can be of maximum duration 180 seconds. If the call duration exceeds 180 seconds, then system will automatically release the call. User Interaction Welcome Message Language Selection Call Limit

100. Welcome Message –When a user accesses a subscriber service, the system can play the welcome message to the user, which is customized by the service subscriber and can be configured on the service subscriber level. If the service subscriber selects the welcome message, the welcome message will be the first announcement in the subscriber service and cannot be interrupted. Features

101. How it works In PTCL this service is 0800 service To access the service user dials the 0800- xxxxx number and listen to the prompts as set by the subscriber (usually a company/business) His call can be directed to different number depending upon his selection and or time segment.

112. One card does it all Universal Card

113. Introduction Currently four types of Prepaid cards in use PS, HCD, PPT and UBP. Difficult for both users and PTCL to manage these 4 different cards Huawei suggests creating a universal card solution to increase efficiency and convenience of maintenance.

114. Features The universal card holds all the features that were originally in the prepaid calling card function. The UBP service and PPT service keep all their functions as normal.

115. Scenario 1- How it Works Huawei suggested various scenarios to PTCL earlier and it agreed to scenario 1. The details are below. The original service flow of all service remain same but the databases will be combined into one DB. All cards will unify into one card and features of the cards will be converged Operator issues one type of card.

116. Scenario 1

117. After analyzing the solution and requirement by Huawei R&D, they have suggested an advanced and new solution (Scenario 2). As development on HCD and UBP will be frozen in next version, Huawei is suggesting to merge HCD and UBP service into PPC service. HCD service is already almost like PPC service except its usage location, they can be combined easily Scenario 2

118. In scenario 2, there will be only 2 services instead of the original 4. PPS, HCD and UBP converge into one service, while PPT service remains same. The database for all the services will be combined into one database. Scenario 2 – How it works

119. Scenario 2

120. Scenario 2 – Old Cards To cater for old cards in circulation, the UBP (1226) service flow will be changed to prompt the user as follows: “ The old system have migrated to new system, the access number has changed to 1010, please dial 1010 again and select the UBP function in the main menu, thank you ”, then release the call. This prompt can be stopped until the old cards are almost used up for some while.

121. Example For example a user buys a Universal Card to use for prepaid calling card. He will dial the 1010 number and after following the prompts he will select the call option. He will dial the desired number and he may hang up the call or he can again enter into the prompts menu to use the card for UBP.
