Definitions
- the fixed subscriber number assigned to a subscriber - e.g. the telephone number or the fax number - determined by the affiliation of the communication terminal assigned to the subscriber to a switching system.
- the subscriber number e.g. 636-82963
- the subscriber number assigned to the subscriber usually changes because the communication terminal is either assigned to another switching system or the communication terminal is connected to the same switching system via another subscriber interface.
- a communication system is known from German published patent application DE 196 04 244 A1, in which the communication terminals assigned to a switching system are connected to the switching system via an ATM-based communication network.
- the subscriber interfaces are made available by a plurality of ATM transfer units connected to the ATM-based network - often referred to in the literature as an ATM hub.
- the switching system and the ATM transfer unit each have an ATM connection unit, via which a connection to the ATM-based network is realized on the one hand and, on the other hand, a bidirectional conversion between the data format internal to the switching system or transfer unit and the ATM-based data format he follows.
- ATM asynchronous transfer mode
- An ATM cell is composed of a five-byte long cell header containing the switching data relevant for the transport of an ATM cell, the so-called ⁇ header 'and a 48-byte long user data field, the so-called' payload '.
- Data transmission via an ATM-based network generally takes place in the context of virtual paths or channels.
- Channel identification and switching information consisting of a virtual path identification are set up in the respective ATM network node.
- a so-called VCI value is assigned to the virtual channel identification and a so-called VPI value to the virtual path identification.
- the switching information entered in the connection tables specifies how the virtual paths or the virtual channels contained in the virtual paths of the connections coming in and going out at the ATM network nodes are assigned to one another by the signaling, ie which input with which output are connected in terms of switching technology is linked.
- ATM cells transmitted via these virtual connections essentially have switching data consisting of a VPI and a VCI value in the cell header.
- the ATM cell header data are processed, that is to say the switching data arranged therein is recorded and evaluated.
- the ATM cells are then switched to an output representing a specific destination by the ATM network node on the basis of the switching information stored in the connection table.
- an ATM channel is set up between the ATM transfer unit and the switching system for each communication terminal, ie each subscriber interface of an ATM Transfer unit or each communication terminal connected to a subscriber interface is assigned a unique VPI / VCI address for data transmission by the switching system. So far, the assignment and management of the VPI / VCI address to the respective subscriber interfaces in the switching system has been carried out manually.
- the present invention has for its object to provide a method by which an automatic assignment of a network access address to a communication terminal can be done in a simple manner.
- An essential advantage of the method according to the invention is that by automatically assigning a network access address to a communication terminal connected to the switching system via the communication network, the susceptibility to errors of the system is reduced, in contrast to the manual assignment previously carried out.
- An advantage of embodiments of the invention defined in the subclaims is, inter alia, that by transmitting a personal identification number PIN (Personal Identification Number) and, alternatively or additionally, the transmission of a password.
- PIN Personal Identification Number
- Access to the switching system by unauthorized persons is prevented by a communication subscriber assigned to the communication terminal - frequently referred to in the literature as subscriber authentication - for registering the terminal on the switching system.
- 1 a structural diagram for the schematic representation of the essential functional units involved in the method according to the invention before a communication subscriber moves; 2: a structure diagram for the schematic representation of the essential functional units involved in the method according to the invention after the communication subscriber has moved.
- Fig. 1 shows a schematic representation of two switching systems PBX1, PBX2 (private branch exchange) which are connected via an ATM-based communication network ATM-KN to two ATM transfer units ATM-HUB1, ATM-HUB2.
- the ATM-based communication network ATM-KN consists, for example, of three network nodes NK1, NK2, NK3, the first switching system PBX1 via the first network node NK1, the second switching system PBX2 and the first ATM transfer unit ATM- HUB1 via the second network node NK2 and the second ATM transfer unit ATM-HUB2 via the third network node NK3 are connected to the ATM-based communication network ATM-KN.
- the ATM transfer units ATM-HUB1, ATM-HUB2 each have n subscriber interfaces TSS1, ..., TSSn for connecting communication terminals to the ATM-based communication network ATM-KN. Examples are about. Subscriber interface TSS1 of the first ATM transfer unit ATM-HUB1, a first communication terminal KE-A assigned to a first communication subscriber and connected via the subscriber interface TSS1 of the second ATM transfer unit ATM-HUB2, a second communication terminal KE-B assigned to a second communication subscriber .
- ISDN communication terminals (_Integrated Services Digital Network) or interfaces derived therefrom, such as, for example, U p0 , are usually used via the ATM transfer units ATM-HUB1, ATM-HUB2 using So interfaces.
- a U P0 or an S 0 interface comprises on the one hand 2 user data channels, which are designed as ISDN-oriented B channels with a transmission rate of 64 kbit / s each, and on the other hand a signaling channel, which is configured as an ISDN-oriented D- Channel is designed with a transmission rate of 16 kbit / s.
- a signaling channel which is configured as an ISDN-oriented D- Channel is designed with a transmission rate of 16 kbit / s.
- analog communication terminals to the ATM-based communication network ATM-KN via a / b interfaces.
- This time slot-oriented data - consisting of two B channels and one D channel - is usually transmitted between the communication terminals KE-A, KE-B and the switching system connected to the ATM transfer units ATM-HUB1, ATM-HUB2 based on, for example from the product brochure "ICs for Communications - IOM ® -2 Interface Refe- rence Guide "from Siemens, Kunststoff, 3/91, order no. B115-H6397-XX-7600, in particular pages 6 to 12 of the known data format IOM-2.
- the switching systems PBX1, PBX2 and the ATM transfer units ATM-HUB1, ATM-HUB2 each have an ATM connection unit (not shown) via which a connection to the ATM-based communication network ATM-KN is realized on the one hand and on the other hand a bidirectional conversion between the IOM-2 data format and the ATM data format, which is usually provided for data transmission between the switching systems PBX1, PBX2 and the ATM transfer units ATM-HUB1, ATM-HUB2, takes place.
- a bidirectional conversion between the IOM-2 data format and the ATM data format can be carried out either according to the method known from German laid-open specification DE 196 04 244 AI or according to the method proposed in the German patent application with the official identification number 198 39 129.3 .
- the first communication terminal KE-A is assigned to the second switching system PBX2 and the second communication terminal KE-B is assigned to the first switching system PBX1.
- the literature frequently speaks of the fact that the first communication terminal KE-A is registered at the second switching system PBX2 and the second communication terminal KE-B is registered at the first switching system PBX1.
- the address of the second switching system PBX2 - hereinafter referred to as system address AA2 - and an address clearly assigned to the first communication terminal KE-A in the ATM-based communication network ATM-KN are stored in a memory of the first communication terminal KE-A. address EA-A designated - saved.
- the address of the first switching system PBX1 is in a memory of the second communication terminal KE-B - furthermore with System address AAl denotes - and an address assigned to the second communication terminal KE-B, which is clearly assigned in the ATM-based communication network ATM-KN - hereinafter referred to as the terminal address EA-B.
- the first communication terminal KE-A can be uniquely addressed in the ATM-based communication network ATM-KN.
- the terminal address EA-B of the second communication terminal KE-B and one of these terminal address EA-B are assigned in a configuration table KT1 stored in the first switching system PBXl Network access address VCI4 stored.
- the second communication terminal KE-B can be uniquely addressed in the ATM-based communication network ATM-KN.
- FIG. 2 shows a schematic illustration of the assignment of the communication terminals KE-A, KE-B after the first communication subscriber has moved. Due to the move of the first communication subscriber, the assignment of the first communication terminal KE-A assigned to the first communication subscriber to the subscriber interfaces TSS1, ..., TSSn of the ATM transfer unit ATM-HUB1, ATM-HUB2 has changed. Thus, the first communication terminal KE-A is no longer connected to the ATM-based communication network ATM-KN via the subscriber interface TSS1 of the first ATM transfer unit ATM-HUB1 but via the subscriber interface TSSn of the second ATM transfer unit ATM-HUB2.
- the network access address VPI3 stored in the second switching system PBX2 in the configuration table KT2 is necessary for the first communication terminal KE-A so that the second switching system PBX2 to the first communication subscriber calls are forwarded via the ATM-based communication network ATM-KN to the subscriber interface TSSn of the second ATM transfer unit ATM-HUB2.
- the second ATM transfer unit ATM-HUB2 sends a configuration message containing the terminal address EA-A of the first communication terminal KE-A via the third route LW3 to the second switching system identified by the system address AA2 stored in the first communication terminal KE-A PBX 2 - often referred to in the literature as ⁇ Home PBX 'the first communication terminal KE-A.
- the second switching system PBX2 determines a new network access address VCI9 - that is, an ATM-based VPI / VCI address - for the first communication terminal KE-A and enters this in the appropriate place in the configuration table KT2.
- the first communication terminal KE-A is registered as new on the second switching system PBX2.
