  • Each subscriber will generally be given a block of televoting number ranges to conduct a televoting event.
  • the blocks are no more than 100 numbers wherein the last two digits of a televoting number is used to identify a choice or an option where callers can register their votes or answers.
  • Televoting events are run within a limited time frame and as such not all callers are able to register their votes or choices within the time interval over which the televoting event runs. This requires each of the calls received to be handled by the intelligent network in three stages, namely before the start time of the televoting event, during the televoting event itself and after the finish time of the event.
  • the treatment of calls received to a televoting event has to be done separately for each block of numbers, so that three separate operations need to be sent to each SSP for each block of numbers.
  • One operation is required for the treatment of the numbers received before the event starts, another operation for the televoting event itself and a third operation for the treatment of numbers received after the televoting event has finished.
  • a large amount of time and effort has to be utilised to set the appropriate operations in each SSP at various times which is also a time consuming process.

  • Each ten digit number 32 represents a televoting destination number which a caller may call whereby each of the numbers 32 represent a choice or option for that caller to register their vote or to register an answer. Therefore each televoting number is identified by the last two digits 36.
  • certain parameters will be transmitted from the SCP 6 to each of the SSPs 4 so that each SSP 4 is programmed to handle incoming calls from callers to the televoting event in accordance with the parameters.
  • each SSP 4 prior to the start time of the televoting event signals are transmitted using the INAP from the SCP 6 to each SSP 4 to the effect of blocking any incoming calls from prospective televoters. This is done by loading a memory located within each SSP with for example the first four digits of the block 30 of the televoting number range or alternatively five or six of the first digits of each of the numbers 32.

  • This field indicates the number of counters to be reserved for a televoting event.
  • SSPs 4 are to handle incoming calls to a televoting event. For example, if there are two televoting numbers available for the televoting event, these numbers will be activated and calls to each of these numbers counted in each SSP 4. The count value may be incremented by one for each call received to that number and where each counter is set with a predetermined value N so that only the Nth caller associated with the value N may be routed through to the SCP 6 over the links 8. Therefore only the Nth caller will be routed to the SCP 6 for further treatment whilst all other calls received at the SSP will be terminated with an announcement such as "Your vote has been registered. Unfortunately you have not been successful in reaching the next stage of the contest". This is where a televoting event has offered prizes to certain callers. It acts as a type of filter so that the telephone network is not congested within the short period of time that the televoting event is running.
  • the time when the televote is activated If the time is earlier than the present time, or if it has not been set at all, the televote is started immediately. Otherwise, the vote will be started at the defined time.
  • All of these parameters are loaded into the SSPs from the SCP as mentioned previously.
  • a normal televote will run from the start time until the finish time in accordance with the filtering criteria set in the televoting event.
  • the incoming calls are then treated in each SSP in the same manner as normal filtered televoting calls are treated as defined in the ETSI Core INAP CS-1 standard.
  • the SSP 4 When a call is received by an SSP 4 , the SSP 4 will determine if the televoting event is in progress from the start time, finish time and the televoting destination numbers. If the event is running then the incoming call to that destination number will be treated in accordance with the filtering criteria set in the SCP 6. If however the call is received prior to the start time or after the finish time, the call will be blocked in accordance with the comparison step in the SSP 4 mentioned previously. Therefore, by way of example, when the televoting event is finished, whereby each clock in each SSP 4 senses the finish time, calls to the televoting numbers will again be blocked. Therefore any incoming call to the televoting event after the finish time will have its first four or five digits sensed and decoded in each
  • the SSP 4 on receiving a call to one of the televoting destination numbers in the range of televoting numbers, will check whether or not the televoting event is running. If it is not presently running the call will be blocked and if it is running the call will be subject to the filtering criteria which overrides the blocking process.

  • the call is then received at one of the SSPs 4 at step 44 and a determination is made at step 46 as to whether the particular televoting event is running. This is done by comparing the first four or five digits in the televoting destination number with the first four or five digit string in the incoming call.
  • Each SSP would be expecting a televoting number for example to have the first four digits as 1900.
  • this string is not sensed then it is recognised as not being a number directed to a televoting service and if there is a match then these particular calls will be blocked at step 48 if the televoting event is not running and an announcement issued to the caller at step 50 to the effect that the televoting event is not presently running. If the televoting event is running wherein each SSP has instructions for processing calls to the event during the time it is running, then each received call is counted in the SSPs at step 52 and any pre-arranged filtering criteria set in the SSPs is applied at step 54.
  • a particular announcement may be issued to the caller at step 56 such as "Your call has been counted, thank you for calling this televoting service", or "Your vote has been registered and your call will be transferred to the next stage of processing in the contest".
  • all of the calls counted in each SSP is progressively transmitted to the SCP at step 58 wherein the SCP processes those results.
  • each of the counters in the SSPs may be reset to continue counting the calls received during the televoting process.
  • the present invention particularly has advantages to the network operators wherein they can define a large range of televoting numbers in one go and therefore make the management of the number range much easier. It also facilitates a service design since the service does not need to take care of calls received before and after the event is executed and no particular knowledge of the B-party number is required.

Abstract

L'invention concerne un procédé et un système permettant d'acheminer les appels vers un événement de vote à distance, à l'aide d'un réseau intelligent. Le procédé de cette invention consiste: à recevoir, au moyen de commutateurs d'accès aux services (SSP)(4), des appels téléphoniques effectués par les appelants; à bloquer, sur la base de certains paramètres envoyés par un point de commande du service (SCP)(6) et mémorisés par chaque SSP (4), les appels destinés à plusieurs numéros de vote à distance si ledit événement de vote à distance n'a pas encore débuté; et enfin à activer un ou plusieurs numéros appelés de sorte que ceux-ci peuvent recevoir et traiter les appels, sur la base des paramètres susmentionnés, une fois que l'événement de vote à distance a débuté.
