  • the invention relates to a method and to an arrangement which relate to a mobile telephone network which is utilized by a plurality of mobile telephone stations. More particularly, the invention relates to a telephone system subscriber service arrangement and to a method of directing calls in a telephone system.
  • a business telephone subscriber may have a cordless telephone that makes him at least partially reachable when he is away from his office.
  • the European patent application EP 462727 A2 describes how a limited number of mobile telephone stations in a mobile telephone network are given access to business services that normally only are available to the business telephone sub ⁇ scribers using the private exchange (PABX) . According to the European application, only mobile stations located in a limited area in the mobile network close to the private exchange are given access to the services. The application does not explain how services can be accessed by mobile stations located in a wide area. Employees who need to make and receive telephone calls wherever they are, have to use mobile telephone stations that have no direct connection to a PABX.
  • PABX private exchange
  • the alternatives available today are to use either a stationary PABX telephone or a cordless telephone with limited range of use, using a private numbering plan, or a mobile telephone station with full mobility but with no PABX connec ⁇ tion, using a public numbering plan.
  • One object of the present invention is thus to enable a user of a mobile telephone in a mobile telephone network to use subscriber services which are normally only available to subscribers located in a private telephone network.
  • the intention of the invention is to enable the user to avail himself/herself of the subscriber services irrespective of where the mobile telephone is located in the mobile network.
  • This object is achieved with an inventive arrangement which is connected to both the mobile telephone network and to the private network, and by an inventive method by means of which any call from the mobile telephone can be directed to the inventive arrangement irrespective of where the mobile telephone is located in the mobile telephone network.
  • Another additional object of the invention is to enable use of services even if the user is located in a mobile telephone network other than the one connected to the arran- gement. This object is achieved by another inventive methodby means of which any call can be directed to the inventive arrangement.
  • the advantage with the invention is that the subscriber can act as if he/she belongs to the private network even if he/she is located in any of the mobile telephone networks connected to the private network.
  • Figure 1 shows schematically a telephone system according to the present invention and illustrates an inventive method of directing a call from a mobile telephone to the inventive arrangement
  • Figure 2 shows schematically a telephone system according to the present invention and illustrates an inventive method of directing a call from a mobile telephone in a first mobile telephone network to the inventive arrangement in another mobile telephone network.
