Method and array for determining internet protocol addresses of a terminal array
The invention relates to a method and an array for determining the IP addresses of a terminal array connected to an IP network by means of a telecommunication network. A pseudo-hardware address is administratively assigned as identifier to the subscriber connection of the terminal array. Said identifier is stored in the peripheral area of the telecommunication network and transmitted in an IP address request by the terminal array to a network management unit for assigning IP addresses. Said network management unit assigns an IP address using the identifier of the terminal connection and transmits said address to the terminal array.
1. A method for determining an IP address that is uniquely assigned to a terminal arrangement connected to an IP network via a subscriber line of a telecommunications network, comprising the following steps of:
allocating a unique identifier to the terminal arrangement by a network management device of the IP network;
storing of the unique identifier in the peripheral area of the telecommunications network and in a network management unit for assigning IP addresses;
assigning an IP address by the network management unit, taking into account the unique identifier stored in the network management unit;
sending an IP address request message from the terminal arrangement to the network management unit, where the message contains the unique identifier previously stored in the peripheral area; and
sending the assigned IP address from the network management unit to the terminal arrangement as response to the received IP-address request message;
wherein the unique identifier in the peripheral area of the telecommunications network is stored in a network element, assigned to a number of subscriber lines, and is transferred to the terminal arrangement on initialization of the terminal arrangement.
2. The method as claimed in claim 1 , wherein the identifier is saved as part of subscriber-line port data.
3. The method as claimed in claim 1 , wherein the identifier is stored—in particular permanently or temporarily—in the terminal arrangement.
4. The method as claimed in claim 1 , wherein the identifier is stored in the terminal arrangement on configuration of a subscriber line.
5. The method as claimed in claim 1 , wherein the IP address to be sent in response to IP-address requests is permanently assigned when storing the identifier in the network management unit.
