Definitions

  • the present invention relates to a procedure for setting up a call in a wireless local loop based on mobile communication technology, in which subscriber's stations are connected via a radio link to an access node and from the access node to a local exchange in a wired network.
  • a subscriber's station is connected via a wireless link to an access node or a WLL controller.
  • the access node may consist of multiplexers, crossbar switches and various transmitting systems.
  • the WLL system may be based e.g. on technology used in mobile telephone systems, such as the GSM/DCS1800 technology (GSM, Global System for Mobile Communications; DCS, Digital Cellular System) .
  • GSM Global System for Mobile Communications
  • DCS Digital Cellular System
  • GSM Global System for Mobile Communications
  • DCS Digital Cellular System
  • GSM Global System for Mobile Communications
  • DCS-1800 is a mobile communication system standardized by ETSI, which is based on the GSM specifi- cation and aims at a more effective use of microcells and which works in the frequency range of 1800 MHz.
  • the WLL controller can be connected to the telephone exchange using e.g. the V5.2 or V5.2 protocol .
  • ETSI European Telecommunications and Standards Institute
  • V5 interfaces enable subscribers belonging to a physically separate access network, which may be either a wi- red or a wireless network, to be connected to a telephone exchange using a standard interface.
  • a dynamic concentrator interface V5.2 consistent with the standards ETS 300 347-1 and 347-2 consists of one or more (1 - 16) PCM (Pulse Code Modulation) cables.
  • One PCM cable comprises 32 channels, each of which with a transfer rate of 64 kbit/s, i.e. 2048 kbit/s in all.
  • the V5.2 interfa- ce supports analogue telephones as used in the public telephone network, digital, such as ISDN (Integrated Services Digital Network) basic and system subscriber connections as well as other analogue or digital terminal equipment based on semi-fixed connections.
  • the dialling information when the dialling information is to be transmitted from an access node based on a mobile communication system to a local exchange in a wired network, the message-based dialling information consistent with mobile communication specifications has to be converted in the access node into a voice- frequency multifrequency code (MFT, multifrequency tone or DTMF, dual tone multifrequency) acceptable to the local exchange.
  • MFT voice- frequency multifrequency code
  • the problem is that generating such signal tones is slow because the signal tones and the intervals between them should have a certain duration according to recommendations of the CCITT (CCITT, International Brass and Telephone Consultative Committee, working under ITU; ITU, International Telecommunication Union, working under the UN) , which retards call setup.
  • CCITT International Committee, International Brass and Telephone Consultative Committee, working under ITU; ITU, International Telecommunication Union, working under the UN
  • the object of the invention is to eliminate the drawback mentioned above.
  • a specific object of the invention is to present a procedure that allows faster setup of a call from an access node to a local exchange in a wired network.
  • the procedure of the invention is characterized by what is presented in claim 1.
  • the message-based dialling information consistent with mobile communication specifications is con- verted in the access node into message-based dialling information consistent with the signalling used in the interface between the local exchange and the access no- de, and this information is transmitted to the local exchange .
  • the invention has the advantage that it enables faster call setup from an access node to a local exchan- ge in a wired network.
  • the subscriber's station is connected to the access node via a GSM/DCS interface, in which case the dialling information given by the subscriber's station is in accordance with the GSM specification.
  • the signalling from the subscriber's station to the network is therefore implemented using signalling consistent with the GSM standard.
  • the subscri- ber ' s station is connected from the access node to the wired network local exchange via a V5 interface consistent with the ETS 300 347-1 standard, and the message- based dialling information consistent with mobile communication specifications is converted in the access node into message-based dialling information consistent with the ETS 300 324-1 specification.
  • the message- based dialling information consistent with the ETS 300 324-1 specification is transmitted in the form of so-called SIGNAL messages via the signalling channel of the V5 interface to the local exchange .
  • the figure presents a wireless local loop WLL comprising a number of subscriber's stations MS, which communicate with an access node AN over a radio link.
  • the signalling between the subscriber's station MS and the access node AN is message-based signalling consistent with the GSM specifications (GSM/DCS1800) .
  • the ac- cess node AN again is connected to a local exchange LE in a wired network via a V5.2 interface consistent with the ETS 300 347-1 standard.
  • the message-based dialling in- formation consistent with the GSM specification is converted into message-based dialling information consistent with the ETS 300 324-1 standard, and this information is transmitted in the V5 interface as message-based signalling in the form of so-called SIGNAL messages via the signalling channel of the V5 interface to the wired network local exchange LE .
  • SIGNAL messages means that the PSTN protocol (one of the five network layer protocols of the V5.2 interface) is used. Therefore, WLL subscribers are interpreted in the local exchan- ge as being normal analogue subscribers. If desirable, WLL subscribers can also be regarded in the local exchange LE as ISDN 2B+D subscribers.
  • the message-based dialling information can be transmitted to the wired network local exchange LE via the signalling channel reserved for the subscriber in the V5 interface in the form of ISDN signalling messages (LAPD signalling) .
  • LAPD signalling ISDN signalling

Abstract

L'invention concerne un procédé servant à établir une communication dans un circuit local sans fil (WLL) en fonction d'une technique de communication mobile, dans lequel des postes d'abonné (MS) sont reliés par l'intermédiaire d'une liaison radio à un noeud d'accès (AN) et, depuis ce noeud d'accès, à un centre de rattachement (LE) dans un réseau câblé. Afin d'établir la communication plus rapidement, l'information de numérotation à base de message conforme aux normes de communication mobile envoyées par un poste d'abonné, est convertie dans le noeud d'accès (AN) en information de numérotation à base de message conforme à la signalisation utilisée dans l'interface entre le centre de rattachement et le noeud d'accès et cette information est transmise au centre de rattachement.
