  • the technology is especially useful in connection with broadband upgrading of the access network because it allows "realization” of a "second telephony subscription" over the 0 broadband IP-equipped channel, based on a comparatively simple and cheap solution.
  • This second subscription also allows a coverage area restricted mobility (For instance the home/the school/the youth centre/%)
  • Figure 1 shows the physical architecture of the system according to the present invention
  • Figure 2 shows the protocol architecture between a DECT-terminal (PP) and a base station (FP) .
  • the DECT-standard actually only defines radio access and belonging signalling.
  • the underlying network for handling of mobility and switching is actually not defined but a number of goal networks, i.a. ISDN, POTS and GSM are indicated.
  • the DECT-standard defines generic mechanisms which the underlying network must have in terms of "Home Database” (HDB) and "Visitor Location Database” (VDB) .
  • the basic idea of this invention instead is to use Internet as goal network and base mobility handling on Mobile-IP, and the voice switching on "Voice-Over- Internef-technology .
  • the DECT-terminal correspond to, in the IP-world, a "proxy" which to Internet just looks like an Internet-telephony-equipped computer.
  • the interface II is the ordinary DECT-interface .
  • the interface 12 is an IP-based interface which is identical to the interface which a computer equipped with Internet-based telephony makes use of in order to via a gateway (GW) communicate with terminals in PSTN and/or the ISDN-notwoi k . 13 constitutes a normal POTS-interface .
  • the interface 14 is used by GW for incoming calls from PSTN to convert the "telephone number" of the DECT-terminal to corresponding IP-address.
  • the interface is also used by FP in connection with the "location update"-procedure to translate from IPUI to IP-address (because the DECT-mobile does not know “its" IP-address).
  • Each mobile DECT-terminal consequently must be allocated a unique IP-address.
  • the database has been arranged in order to make calls from PSTN/ISDN as transparent as possible. If the solution is used in the application "2:nd subscription” and "ordinary" DECT- telephone number is 7075560, the DECT-teiminals of the home can be allocated number #7075560n, where n is a digit between 1 and 9 which acccordingly makes possible up to 9 mobile terminals.

After that Sven can answer in usual way.
  • FP keeps count of where Sven is, i.e. if Sven is in ordinary DECT-coverage area, or in another acknowledged DECT-coverage area. It also should be realized that when Sven moves between two DECT-coverage areas, Sven can not be accessed via his telephone. FP in ordinary DECT-coverage area has no knowledge of where Sven is, but just observes that Sven is out of the coverage area.

Abstract

L'invention concerne un système destiné à un système de télécommunications et de communication de données sans fil. Ce système permet la mobilité des terminaux à l'aide de la technologie DECT et de l'Internet. Les terminaux DECT sont actuellement utilisés pour une mobilité réduite de la zone de desserte. La technologie est avantageuse en termes de coût, mais la mobilité est comparativement réduite. Une mobilité simple et peu coûteuse entre les zones de desserte DECT fait défaut et est donc souhaitable. L'invention a pour objet d'apporter une mobilité étendue du système DECT à l'aide d'un protocole Internet. L'invention est basée sur la norme 'mobile IP', selon laquelle des ordinateurs reliés à l'Internet disposent d'une fonction leur permettant de se déplacer entre différents points de connexion à l'Internet sans nécessiter une importante reconfiguration du terminal et/ou des éléments réseau.
