Arrangements for controlling network elements
First Claim
1. An arrangement for controlling network elements in a telecommunication network comprising:
- a plurality of network elements;
a transmission network;
a network management system for controlling the network elements remotely by using modem connections via the transmission network;
wherein the network management system is connected to the transmission network with a first set of modems and a second set of modems;
the first set of modems is used for connections between the network management system and a network element initiated by the network management system; and
the second set of modems is used for connections between a network element and the network management system initiated by the network element.

Abstract
The idea of this invention is to use at least two modems on the network management system side. At least one of these modems is used only for connections initialized by the network management system. At least one other modem is used only for connections initialized by any or a group of network elements controlled by the network management system. The number of modems used for connections initiated by the management system may be more than one, thus enabling the network management system to initiate simultaneous connections to more than one network element. Likewise, more than one modem can be assigned for connections initiated by the network elements.

a group is allocated a group specific modem from the second set of modems and when establishing a connection to the network management system, a network element belonging to the group directs the connection via the group specific modem. -
5. An arrangement according to claim 1, wherein
at least one network element is given a subset of at least two modems from the second set of modems and when initiating a connection with the network management system, the network element establishes the connection using a modem belonging to this set. -
6. An arrangement according to claim 5, wherein
the subset of modems is given a priority order and, when initiating a connection with the network management system, the network element tries to establish a connection using the modems in the priority order until the establishment is successful. -
7. An arrangement according to claim 1, wherein at least some of the network elements are radio repeaters.

8. A network management system for a telecommunication network comprising:
-
a plurality of network elements;
a transmission network;
a network management system for controlling the network elements remotely by using modem connections via the transmission network;
wherein the network management system is arranged to be connected to the transmission network with at least a first set of modems and a second set of modems;
initiate connections towards the network elements using the first set of modems; and
take part in connections using the second set of modems and being initiated by the network elements.

9. A network element for a telecommunication network comprising:
-
a plurality of network elements;
a transmission network;
a network management system for controlling the network elements remotely by using modem connections via the transmission network;
wherein the network management system is connected to the transmission network with a first set of modems and a second set of modems;
the first set of modems is used for connections between the network management system and a network element initiated by the network management system; and
the second set of modems is used for connections between a network element and the network management system initiated by the network element;
and wherein the network element is arranged to receive knowledge of a subset of at least two modems of the second set of modems and a priority order for the subset and use the subset in the priority order when initiating a connections with the network management system. - View Dependent Claims (10)
