Definitions

  • the present invention relates to call charging in a telecommunications system and, more particularly, to a method of and a telecommunications system for charging calls at a charging rate to be determined.
  • Reverse charging that is the called party bears the costs for the call, is made possible by a service called "collect-call". Through a telephone operator, the called party can agree to collect the charges for the call .
  • operators of mobile telecommunication networks offer lower costs per time unit (i.e. per second or per minute) or higher charging rates against lower subscription fees, for example.
  • a local network operator may take advantage therefrom, by offering subscriptions such as low international call charges compared against higher local charging rates or, visa versa, low local charging rates against more expensive international call charges.
  • subscriptions such as low international call charges compared against higher local charging rates or, visa versa, low local charging rates against more expensive international call charges.
  • EP-0,608,066 and the corresponding US patent 5,515,425 disclose a telecommunication system having a so-called "active" database in which charging rate information of several operators is stored.
  • the term "active" has to be construed in that the data base is updated with each change in the charging rate, for example, based on the time of the day or calling patterns that may develop in a particular network.
  • This rate data base may be accessed on a call-by-call basis and the information retrieved may be provided to switching equipment, such as a PABX, in order to automatically route a call to the lowest-cost provider or network.
  • WO 97/05749 provides a call management system for determining an optimum telecommunication network or carrier, based on the least costs for completing a call. Likewise, a rate or tariff information data base is provided.
  • the actual charging of a call is made dependent on charging rates which are applicable if such call would be handled by other operators, other networks, other international and global carriers, if applicable, different call directions etc., provided the same or equivalent resources are used and at the same time of placing the call. Contrary to the prior art identified above, selection of the most optimum (e.g. cheapest) carrier and/or routing of the call through a selected operator is not an issue of the present invention. This can be best explained in some examples.
  • the call can be pretty costly.
  • a telecommunications service provider or network operator may offer to charge the call against the rate as if the call was placed from the company to the employee.
  • a first party having a subscription with a first network operator under the condition of low rate local calls and expensive charging rates for international calls.
  • a second party has a subscription with the same network operator, which provides for low international charging rates and more expensive local calls.
  • the network operator or communications service provider may offer to charge the least expensive charging rate applicable. In the above case, the calling rate from the second to the first party.
  • the network operator may also offer to charge this call against a charging rate which would be charged by an other operator in the service area of the first party, if such charging rate is lower and provided equivalent system resources will be used (e.g. the same quality) and at the same time of the day.
  • a charging rate which would be charged by an other operator in the service area of the first party, if such charging rate is lower and provided equivalent system resources will be used (e.g. the same quality) and at the same time of the day.
  • a charging rate which would be charged by an other operator in the service area of the first party, if such charging rate is lower and provided equivalent system resources will be used (e.g. the same quality) and at the same time of the day.
  • a network operator will offer this flexible charging method as a novel service, available on a subscription basis, for example.
  • charging rate right can be offered. Such that, if a user of the telecommunications system is provided with a charging rate right, the call is charged by applying a charging rate selected in accordance with the charging rate right.
  • the network operator or communications service provider applies a particular charging rate without actually adapting the network resources to the charging rate applied. For example, if a call from a called party to a calling party is less expensive, than the communication path i.e. the system resources used, will actually not be changed.
  • the method according to the invention in a further embodiment thereof, provides also for establishing a call using the system resources corresponding to the charging rate to be applied.
  • the selection of system resources can be implemented in exchange equipment of the communications system or, alternatively, in the Private Automatic Branch exchange (PABX) or other equipment of the user or subscriber.
  • the charging rate information in a yet further embodiment of the method according to the invention, is made available from charging data base equipment of the telecommunications systems i.e. the wired and/or wireless networks involved.
  • the charging rates can be made available from charging data base equipment of one or both the calling and called party.
  • the charging rates are acquired and processed through signalling and processing resources provided by the telecommunications system. This puts the least requirements on subscribers, which can benefit from the novel and inventive charging method according to the invention without having to change or adapt their communication equipment.
  • a call is set up after the charging rate to be applied has been selected. This to avoid occupation of scarce resources.
  • the telecommunication system may provide the same signalling tones and the like as with a "normal" call set up. Accordingly, callers do not have to experience the selection of charging rates and/or an actual selection of system resources if a call is set up from the called party, for example.
  • the invention further provides for a telecommunications system, comprising wired and/or wireless telecommunication networks, each such network comprising exchange equipment arranged for establishing a communication link between a calling and called party by processing signalling information provided, and charging means for charging the call in accordance with the processed signalling information, characterized in that the charging means are arranged for providing charging rates applicable at the time of and for using such system resources required for establishing the call and for charging the call following one of the applicable charging rates.
  • the charging means may be arranged for charging the least expensive rate applicable and/or for applying the applicable charging rate dependent on a charging rate right of one or both parties involved in a call.
  • the exchange equipment of the telecommunications system may be arranged for establishing a communication link following the charging rate to be applied. That is, the communication link is set up from or using those system resources which are associated with the selected charging rate.
  • SSP Service Switching Point
  • SCP Service Control Point
  • the invention further relates to SCP equipment and telecommunication terminal equipment arranged for the charging of calls following the invention.
