Abstract
A method of adapting the characteristics of a call server to optimise the call server's performance and usage of available network resources. A network management element determines the impact of any changes in the condition of the network on the call server and provides an indication to the call server which resets at least one characteristic of the call server to optimise the call server's performance.
Claims18
A method of adapting a routing algorithm used by a call server connected to a communications network comprising the steps of:
- detecting a change in at least one condition of the communications network;
- analyzing the change to determine whether the routing algorithm requires adaptation to accommodate said change;
- and, in the case of the routing algorithm requiring adaptation,
- providing an indication of the required adaptation to the call server;
- and
- receiving the indication at the call server and adapting the routing algorithm used by the call server in response to said indication.
A method of modifying at least one characteristic of a call server in a communications network which includes a network management element capable of monitoring a condition of the network, the method comprising:
- generating an indication of the condition of the network providing sufficient information for the call server to utilise available network resources;
- sending the indication to the call server;
- receiving at the call server the indication of the condition of the network;
- and
- modifying said at least one characteristic in accordance with said indication to enable the call server to utilise the available network resources.
A network management element capable of determining a condition of a communications network and capable of communicating said condition with a call server connected to the network for use in a method of adapting a routing algorithm used by a call server connected to a communications network, the method comprising the steps of detecting a change in at least one condition of the communications network;
- analyzing the change to determine whether the routing algorithm requires adaptation to accommodate said change;
- and, in the case of the routing algorithm requiring adaptation, providing an indication of the required adaptation to the call server, and
- receiving the indication at the call server and adapting the routing algorithm used by the call server in response to said indication, the network management element being adapted to correlate information received from a packet backbone network relating to the condition of the network with an instruction set comprising at least one informational element, each informational element providing an instruction to a call server to modify at least one of the characteristics of the call server so as to optimise the manner in which the call server utilises the available resources of the packet backbone network.
A call server adapted for use in a method of adapting a routing algorithm used by the call server connected to a communications network, the method comprising the steps of:
- detecting a change in at least one condition of the communications network;
- analyzing the change to determine whether the routing algorithm requires adaptation to accommodate said change;
- and, in the case of the routing algorithm requiring adaptation, providing an indication of the required adaptation to the call server;
- and receiving the indication at the call server and adapting the routing algorithm used by the call server in response to said indication, wherein the call server includes:
- a receiving element for interfacing with said indication;
- an processing element for processing information provided by said indication;
- and
- a routing algorithm adapting element for adapting said routing algorithm.
A routing algorithm for a call server adapted for use in a method of adapting a routing algorithm used by a call server connected to a communications network, the method comprising the steps of:
- detecting a change in at least one condition of the communications network;
- analyzing the change to determine whether the routing algorithm requires adaptation to accommodate said change;
- and, in the case of the routing algorithm requiring adaptation, providing an indication of the required adaptation to the call server;
- and receiving the indication at the call server and adapting the routing algorithm used by the call server in response to said indication, the routing algorithm operable in accordance with a set of rules which determine route selection over a communication network, at least one rule capable of being adapted in response to the call server receiving an indication relating to the adaptation of the said at least one rule.
A communication network having means to modify a characteristic of a call server for use in a method of adapting a routing algorithm used by a call server connected to a communications network, the method comprising the steps of:
- detecting a change in at least one condition of the communications network;
- analyzing the change to determine whether the routing algorithm requires adaptation to accommodate said change;
- and, in the case of the routing algorithm requiring adaptation, providing an indication of the required adaptation to the call server;
- and receiving the indication at the call server and adapting the routing algorithm used by the call server in response to said indication.
