Abstract
The present invention relates to a method of operating a communications network, comprising the steps of: receiving a plurality of packets from a network node; determining a first parameter based on the time period between the reception of a packet and the reception of the subsequent packet; determining a second parameter based on the variation of the first parameter; and determining the performance of the communications network in accordance with the ratio of the second parameter to the first parameter.
Claims18
A method of operating a wireless communications network, the method comprising the steps of:
- a) receiving a plurality of data packets comprising a real time communication session from a network node connected to the wireless communications network;
- b) determining a plurality of packet period parameter values, the data packet period parameter being determine by the time period between the reception of a data packet and the reception of the subsequent data packet;
- c) determining a plurality of jitter parameter values, the jitter parameter being determined by the difference between one data packet period parameter value and the subsequence data packet period parameter values;
- and
- d) determining, using the computer system including a computer processor, the performance of the wireless communications network in accordance with the ratio of an average of the jitter parameter value determine in step c) to an average of the packet period parameter values.
An apparatus for use in a wireless communications network, the apparatus comprising:
- a computer system, comprising a computer processor, the computer system being configure to:
- receive a plurality of data packets comprising a real time communication session from a the wireless communications network;
- determine a plurality of packet period parameter values, the data packet period parameter being determine by the time period between the reception of a data packet and the reception of the subsequent data packet;
- determine a plurality of jitter parameter values, the jitter parameter being determined by the difference between one data packet period parameter value and the subsequence data packet period parameter values;
- and
- determine the performance of the wireless communications network in accordance with the ratio of an average of the jitter parameter values to an average of the data packet period parameter values.
A non-transitory computer-readable medium storing computer executable code, which upon execution by a computer system to provide operation of a wireless communications network, the operation comprising:
- a) receiving a plurality of data packets comprising a real time communication session from a network node connected to the wireless communications network;
- b) determining a plurality of packet period parameter values, the data packet period parameter being determine by the time period between the reception of a data packet and the reception of the subsequent data packet;
- c) determining a plurality of jitter parameter values, the jitter parameter being determined by the difference between one data packet period parameter value and the subsequence data packet period parameter values;
- and
- d) determining the performance of the wireless communications network in accordance with the ratio of an average of the jitter parameter value determine to an average of the determined packet period parameter values.
