FreePhoneTable:>Before INLogic + DataISUP:IAMISUP:IAMTEXLEXLEXSubscriber:Problems related to:Modifying service dataModifying service logicHigh cost of service introductionIn order to provide value added services to the basic telephone service, the following conditions must be respected :All the telephone network users can get the benefit of the provided services without any specific equipment other than their own telephone set.Telephone network operators must have the possibility to answer quickly to the market needs.Existing equipment must be able to provide the new services related mechanisms keeping their basic function (call process) and this, without affecting the existing quality of service.The management of the new functionality set must be flexible.Physically , a service is a software implemented in the network switches and is an additional function to the call process.As any software, a service is made up of :Programs called “service logic”;Data called “service data”.In order to provide services to a maximum number of users, these services must be implemented in all (or in a large part of) the network switches.In a classical telephone network architecture, the implementation of new services involves several problems such as :Lengthy service availability lead time due to the development, the update of the existing switches (or their replacement) and to the installation of the service;Difficulties in service logic and data modification;Possibility to affect the quality of service especially during the introduction phases of new services.LEX: Local ExchangeTEX: Transit ExchangeCalling party

4 Intelligent Network Concept Why an Intelligent Network? SMPSS7VoiceSSP: Service Switching PointSCP: Service Control PointSTP: Signaling Transfer PointSMP: Service Management PointSCPSS7STPThe solution is to centralise the logic process and the service data management in a suitable environment: the Service Control Point (SCP). This environment is telephone network independent.The switches are no more service dependant.The only supplementary function for the call process is the Intelligent Network access function.The Intelligent Network access function is unique for all the services. It can be implemented in a dedicated switch or in all the telephone network switches. These switches are called Service Switching Points (SSP)The consequences are:A lower cost for the telephone network :A single type of switch for all services,No need to modify or change the equipment when providing new services,The Intelligent Network need not be a structure managed by the telephone network.Service delivery times shorter :The duration of a new service implementation is no longer dependant on the telephone network topology (number and type of switches…) so implementation becomes faster.A flexible management of the service logic and data :Centralised management in a suitable environment.The quality of basic service is not affected by new services introduction.SSPSSP

The IN access is done using an overlay architecture.In the end user switch (Local Exchange - LE) and in the transit exchanges (TE) :The user initiates the call from the telephone providing a service access number (SAN) which contains a prefix (0800) and the number to be translated (123456). The CCAF function manages the telephone network calling party access and takes into account its subscription characteristics.The CCF, analysing the service access number, routes the call to the SSP (Upstream 1/2 call).In the SSPThe CCF functionAnalyses the received number and, if it matches an IN call, asks to the SSF function to activate a service. In the given example, the numbering begins with 800. This is called SAC (Service Access Code), which is transmitted to the SSF function.The SSF functionChecks from the received information, the triggering conditions and determines the identification of the service to be activated.Initiates a dialog with the SCF function. The information included in the SSF/SCF dialog components, contain the service identification as well as the number to be translated.In the SCPThe SCF functionUses, once the dialog is open, the service identity (given in the dialog) in order to run the translation service logic.Requests the SDF function to provide the translated number from N° ( in the given example).Requests, through the open dialog with the SSF function, a call towards the translated number (downstream 1/2 call). In the given example, the service logic monitors the call establishment until the call is completed.Is advised when the call is completed and the service logic orders (via SSF) the CCF function to connect both half calls. If the service process is completed, the service logic closes the dialog with the SSF function and the call is monitored by CCF function of the switches.SSPLEXCCFCCFCCFLEXCCFTEXTEXCCAFCCAF

30 Free Phone NumberThe Free Phone Service (FPH) is based on the concept of reverse charging added with many new features of useful capabilities. Users have to dial 11 (Eleven) digits number ABCD, ( common prefix, ABCD unique last four digits). The phone line used for making such calls will not be charged; instead the call charges will be billed against the company or individuals subscribing to the FPH service. The FPH subscriber assigns actual phone lines to receive FPH calls and a routing plan describing call routing based on origin of the call, time of the day, type of the day etc. For the same FPH no. thus it is possible to assign several destination phone nos. It can handle much more calls without any degradation in service.Subscribing to an FPH number is very convenient as a first hand contact number and is very suitable for obtaining general information, booking complaints etc. The service is popular with the business community as by providing an FPH number an user with the casual interest can be provided with relevant information about any product and services, or book an order – all without being burdened by any phone call charges to be paid

These include:Origin-dependent routing: screens and selects a destination for the incoming calls, according to their origin.Date and time-dependent routing: screens and selects a destination for the incoming calls, according to the date and time of the calls.Presorting (prompt and collect routing): the calling party is prompted to enter information, which is used to define the routing of the incoming call. After reception of a menu announcement, the calling party can select one of the proposed options using a DTMF telephone set. The calling party has the right to hit a wrong key several times. The maximum number of retries is configurable. When it is reached, a fault announcement is played.Call distribution-dependent routing: the Service Subscriber can specify the percentage of UPN calls to be routed to a given destination. The algorithm increments the counter of the selected destination and the global call counter, after which it recalculates, for each destination, the current percentages to be used for the next selection. All the counters are reset when the proportions are reached.
42 Universal Personnel Number- Specific Features Service access restrictionsThe Service allows to select service access restrictions for incoming calls. These restrictions include:UPN Black Number: to bar malicious users from accessing their UPN numbers. The Service Subscriber defines the UPN Black Numbers relating to previous fraudulent usage with the Service Provider. The service rejects the calls originating from these numbers and a fault announcement is played.Grey list: to block access to the calling lines declared in the grey list, and unblock this access by entering a PIN.UPN Category Restriction: to restrict calls from certain calling party categories.UPN Black/white list: to specify restriction lists with exceptions. Calls are authorized or rejected according to the prefix or the complete calling number. The Service Subscriber defines black lists, which contain the numbers to be rejected, and white lists, which contain the numbers to be authorized.Call origin restriction: to reject incoming calls from the fixed (national or international) or mobile networks.Authentication: access to the UPN number is controlled by the request and check of a PIN. The PIN is necessary when the Subscriber wants to limit access to his UPN number to certain users. During call set-up the calling party first enters the UPN number, then is asked to enter the PIN in order to authenticate service accessibility. When the maximum number of attempts is reached (the number of wrong pin code inputs is configurable) the call is released. On timeout, the call can be rejected with a service or subscriber announcement or redirected to a UPN Routing Number.Call limiter: to limit the maximum number of simultaneous calls to one of his destinations (UPN Routing Numbers) or his UPN number.Supervision of the number of calls over a period: to supervise the number of calls per UPN number.Traffic type restriction: to restrict access to a UPN number for international incoming calls.Restriction on date: to restrict access to a UPN number during a period defined by a begin and an end date.Restriction on called party: to forbid connection to international UPN Routing Numbers.

The mobile and fixed phones of company users are then included into the company’s PNP (Private Numbering Plan).Multi-site managementThe company may be a group located on several different sites: the VPN service makes it possible for each site to have its own Private Numbering Plan, and calls between sites are considered as calls on private networks.Private Numbering PlanThe Telecom Manager assigns private extensions to the site’s VPN users of the site users. Each VPN user can have more than one company line. Thus, a VPN user can call another VPN user in the same company by simply dialing a unique reduced number of digits.The Telecom Manager can define PABX (Private Automatic Branch Exchange) ranges or/and individual PABX extensions in a site. Private extensions can be defined independently from of a PABX range.The Private Numbering Plan may be either a structured or an unstructured PNP for all the sites of the group.Preferred External Destination –This feature allows a subscribing company to integrate non-VPN lines as preferred external destinations (for instance, partnerships, suppliers, customers, etc) by defining Preferred External Destination (PED) numbers (also called ABD) in the site’s Private Numbering Plan of the site. A PED number is associated with a complete public directory number (fixed or mobile) or a PABX range.Group HuntingThe aim of Group Hunting is to manage the mobility of a VPN user by defining a list of numbers that, that can be called to reach the VPN user.This feature allows routing incoming calls according to a sequential examination of the numbers in a Hunting List. It is activated either for company incoming calls or for incoming calls from an outside company when a VPN user is busy, or does not reply, or is not reachable.A default hunting list, including the four user’s four lines and the voice mail is used if no dedicated hunting list or hunting list was specified for the VPN user.
48 Virtual Private Network IN Call forwardingCall forwarding is a routing feature managed dynamically by a given VPN user or operator when he/she wants to specify an alternative destination to for reaching him/her. Call forwarding has the priority over Group Hunting. This means that if a given VPN user activates call forwarding, the forwarded number is used to call him/her, even he/she has a Hunting List.; Group Hunting is processed when call forwarding is not activated.Call forwarding can be processed in mobile or fixed networks or in company PABXs.There are two types of call forwarding:Call Forwarding Conditional (CFC): on busy, no reply or not reachable conditions.Call Forwarding Unconditional (CFU): no condition.CFU overrulingThis feature enables some privileged calling parties (e.g. secretary or family member) to overrule Call Forwarding Unconditional (CFU) in order to call directly a given VPN user directly.Voice mail managementEach VPN user can have a voice mail in the mobile or fixed network, or in the PABX. The voice mail can be used as a final destination in the management of IN call forwarding or Hunting Lists.Exception listsThis feature allows the screening of incoming and outgoing calls of company users based on two types of lists - named called exception lists - containing “allowed” or “not allowed” numbers.VPN linesA VPN user can have more than one VPN line (e.g. PABX extension, mobile, a fixed phone in home etc). Up to four company lines can be defined for each VPN user. Each line may have its own extension (unstructured numbering) or may be identified by a line code before a unique extension (structured numbering).In the framework of a structured numbering plan, this feature allows a given VPN user to call another VPN user by indicating the called line. Thus, the call is routed according to the used line code directly to the line of the concerned called party’s concerned line. If no line code is dialed, the default destination is used to route the call.
49 Virtual Private Network On-net and Off-net callsOn-net calls are private calls made by VPN users to call other VPN users in the same group.Off-net calls are calls made by VPN users towards the public network For making Off net calls PIN verification is there.On-site and Off-site callsOn-site call: a call is said to be on-site when the cell phone is inside his the user’s site area.Off-site call: a call is said to be off-site when the cell phone is outside his the user’s site area.Forced on Net, Virtual on NetThe VPN service provides for two options regarding private rate charges for calls to public numbers:Forced on Net: enables telephone calls to private numbers in the plan (fixed or mobile), dialed using the public format, to be charged at private rates.Virtual on Net: enables telephone calls to Preferred External Destinations outside the company to be charged at private rates.Account codeThis feature enables you to mark calls made by VPN users of a given group in the company account according to the company activities and organization.Dual invoicingThis feature allows you to bill calls made by a given VPN user either on the corporate account or on his/her personal account.
50 Virtual Private Network Group short numbersGroup short numbers can be defined in the PNP (Private Numbering Plan) at company level.Group short numbers enable VPN users of different sites to access public directory numbers or other PNP short numbers (except another short number of the same group) by just dialing the short number.Welcome numberWelcome numbers are public directory numbers enabling external people (not belonging to the subscribing company) to make calls to dedicated VPN users (for instance, customer information service, technical support, etc). The welcome number is translated into a private number (for instance, group short number, extension or site short number) and is handled by the VPN service as a call made by a CMM user.Remote accessWith the Remote Access (RMTA) feature, VPN users can access the Private Numbering Plan of their site from any handset not belonging to the VPN group (in a national or international context), and take advantage of the VPN services (voice mail access, PED numbers, etc). This access is provided by means of a dedicated service code VPN Service Access Number and authentication.SubstitutionWith the substitution feature, VPN users can access the Private Numbering Plan of their site from any handset of another VPN user of their group, and take advantage of the VPN services and to the rights granted to the said member line (voice mail access, PED numbers etc). This access is provided by means of a dedicated service code and authentication.Follow-on callWith the follow-on call feature, VPN users can initiate, under some certain conditions, a new call without authentication after a remote access, substitution or dual invoicing call, or a new call after a call to the account code service without having to redial the account code.Inter-working with co-operating VPNs This feature enables the VPN platform to inter-work with co-operating VPNs by routing to them or receiving company calls from them.The sites of a group (i.e. a subscribing company) can be dealt with by several co-operating VPNs in different countries.

60 Tele Voting- General Description ScopeThe Caller makes a call to the one of the n VOT numbers (max 50)TelevotingServiceCounterUpdateevery nth callornth callThe VOT service allows a service subscriber to know the number of calls placed to each among several Televoting numbers during some time periods in the PSTN/PLMN/ISDN network. The calls are registered and counted. This service enables to survey public opinion using the telephone network.A special routing can be defined for some calls chosen on counting criteria.VOT applies for national calls only.Maximal10 vote numbers per voting event are offered to the user to express his choice.Each voting choice is associated to a VOT phone number. To express his vote, the user makes a call to the VOT number, and then the corresponding counter is incremented. An announcement is made to thank the user for voting.The VOT service allows a service subscriber to know the number of users who have chosen each televoting number. Televoting numbers are assigned to the televoting event and activated for the time period(s) requested by the service subscriber.The service allows selecting some efficient calls. VOT offers the following "Types of vote" which are ways to select winners:Select one call about n until a certain number max of winners,Select the nth call.For these calls the televoting user is routed to a public network directory number which can be an operator for a winning. For the other calls the users receive a thanks announcement.Independent from the chosen vote type there will be no winner if the game parameter of the voting event is set to zero. In this case all callers get the thanks announcement.After the televoting event is finished, the results registered during the event are available to the service subscriber.Announcementoperator

62 Tele Voting- Service Features Validity periodVOT number can be valid or notcalls placed out of the validity period are routed to fault announcementCounterGlobal vote counterLocal televoting counter per VOT numberWinner counterCounters can be resetValidity period: A VOT number can be valid or not, i.e. attributed by the operator to a subscriber or not. Calls placed out of the validity period are routed to a fault announcement.Counter:Each acknowledged call for a vote number increases a counter related to the dialled VOT number. After every “n”  efficient calls the SMP database is updated with the actual counter values.At any given point of time, all the counters associated to a given vote event can be reset using the operator interface.The counter update for an efficient call is made as follows:read and increment the global vote counter,increment the local Tele-voting number counter with a multiplicative factor of the filtering rate,if call is a winner, increment the local winner counter,if local global counter is a multiple of “SMP Counter Update parameter”, update the dynamic Tele-voting number counters and the dynamic winner counter in the SMP.
63 Tele Voting- Service Features Origin dependent handling:Call handling according to the origin of the call, determined with the first few digits of the calling line for fixed phones or the first few digits of the location number for mobile phones.Two types of routing exist when the Origin Dependent Handling criterion is used:routing to a fault announcement, for the origin areas not defined,routing to a destination (that can be an announcement or a PSTN/PLMN number), for the allowed origin areas.
64 Tele Voting- Service Features Day type dependent handlingVOT call handling depends on day type.Two types of routing exist:routing to a fault announcement, for the forbidden day type,routing to a destination (that can be an announcement or a PSTN/PLMN number), for the allowed day type.This feature is available only without pre-filtering [i.e. filtering rate N=1].This feature enables the service subscriber to specify the handling of the call according to the ‘day type’ of the call. Two types of routing exist when the day type dependent handling criterion is used:routing to a fault announcement, for the forbidden day type,routing to a destination (that can be an announcement or a PSTN/PLMN number), for the allowed day type.The day type is determined from the date of the call. Day types are defined with calendar. By default 10 public calendars are available in the VOT which a subscriber can associate to his VOT number. In addition, the service subscriber can define customized calendars.Up to 16 day types can be defined per calendar. Each day of the year must be associated to one day type. The subscriber may indicate a different destination for each of them (max: 15 branches + branch “else”).When the service provider creates the Tele-voting event he associates one of the calendars to it. From this calendar the day types in the criterion are derived.
65 Tele Voting- Service Features Time dependant handlingVOT call handling depends on time.Two types of routing exist:routing to a fault announcement, for the forbidden time,routing to a destination (that can be an announcement or a PSTN/PLMN number), for the allowed time.Time dependent handlingThis feature is available only without pre-filtering [i.e. filtering rate N=1].This criterion enables to route a call according to the time band the call is set up. The time band is determined from the time of the call. Time band is defined as the interval in which the call will be translated to a given destination.Two types of routing exist when the time dependent handling criterion is used:routing to a fault announcement, for the forbidden time,routing to a destination (that can be an announcement or a PSTN/PLMN number), for the allowed time.Time informationA day can be divided into time bands allowing a separate distribution arrangement for each time band. For a specific translation it will be possible to specify up to 12 time bands in one day defined in hours and minutes with a precision of one second. In fact, there can be up to 11 time bands and the ELSE case.
