Definitions
- the invention has for its object to provide a method by which the problems mentioned are overcome.
- the invention enables communication between the telephone exchange of the Internet subscriber and the Internet subscriber via the Internet session.
- This communication can be used to transmit information (such as incoming calls and the caller's number) to a subscriber via his user channel, via which he is simultaneously in an Internet session.
- the invention is particularly advantageous for an analog subscriber since it only has a single user channel, i.e. no second useful channel and also no D channel.
- An embodiment of the invention is specified by claim 2. According to this embodiment of the invention it is for a subscriber possible to transfer the decision whether he wants to accept an incoming call to the local office, so that this delivers the call if necessary.
- the figure shows the basic technique of the invention.
- a so-called Internet Interworking Unit IWU is integrated in the local exchange, which implements the dial-in node (Point of Presence, POP) on the Internet and closes the modem protocols of the analog subscribers (modem pool is integrated in the IWU).
- the IWU is usually connected to the switching technology via an ISDN primary rate access (ISDN PRI) connection (like a private branch exchange). Messages between the IWU and switching technology are exchanged via the D channel.
- ISDN PRI ISDN primary rate access
- the participant logs in the IWU the dynamic IP address to the switching technology, where it is stored for the further procedure.
- a message is to be sent from the 'switching technology' to an Internet user (e.g. for information about incoming calls)
- this information is passed on by the 'switching technology' to the Internet IWU (D-channel message).
- the message contains the dynamic IP address of the subscriber concerned.
- IWU the Internet IWU
- IP / PPP Message converted into an IP packet and sent to the subscriber (TCP / IP / PPP or UDP / IP / PPP).
- the subscriber sends an IP packet with a special application number to the IWU.
- the special application converts the IP packet into a message, which is forwarded to the switching technology via the D channel, for example. If the IWU is not in the local office of the Internet subscriber, but in another exchange, the messages are exchanged between the exchanges using the SCCP and / or TCAP protocols.
- the route selection is based on the E.164 number of the participant and the E.164 number of the IWU.
- the subscriber connected to the Internet dial-in point can be given information about this call.
- the subscriber transmits his or her request to accept or not to accept the call to the exchange, which then delivers or rejects the incoming call.
- the invention enables the transmission of a message to an Internet subscriber from the local office via the existing user channel.
- a message is sent to the Internet dial-up node in the local office, converted there into an IP packet and sent to the subscriber himself via the subscriber's connection to the Internet.
- the information path from the subscriber to the local office takes place using the same mechanism.
- the subscriber sends an IP packet to the dial-in node, which converts the IP packet into a message that is sent to the local office in question.
