Abstract
A method and device for determining a packet drop indicator, for use in a communication system is described. The method comprises the following steps: A. determining the number of packets sent at a sending side within a first time period; B. determining the number of packets received at a receiving side within a second time period; and C. calculating a packet drop indicator on the basis of said number of sent packets and said number of received packets.

A method of determining a packet drop indicator, for use in a communication system comprising a sending side and a receiving side, comprising the following steps:
- A. determining the number of packets sent at the sending side within a first time period;
- B. determining the number of packets received at the receiving side within a second time period;
- and C. calculating a packet drop indicator on the basis of said number of sent packets and said number of received packets, wherein said sending and receiving sides are different sides connected via a transmission path;
- and wherein said step C is performed at said receiving side, said determining of step A comprises receiving an indication of the number of packets sent by said sending side, and said determining of step B comprises counting the number of received packets.
A method of reporting a number of packets, comprising performing at one side of a communication system comprising a sending side and a receiving side the following steps:
- A. counting a number of packets sent or received within a time period;
- and B. reporting the counted value to the other side, wherein said sending and receiving sides are different sides connected via a transmission path;
- and wherein said time period is determined by detection of receipt of successive trigger messages.
A control device for a sending side of a communication system comprising said sending side and a receiving side that are different sides connected via a transmission path, comprising:
- a counter for counting a number of packets sent at the sending side within a predetermined time period, and a count value handler for handling a count value determined by said counter in a procedure for determining a packet drop indicator;
- and a trigger message response element for determining said time period on the basis of trigger messages sent successively by said sending side.
A control device for a receiving side of a communication system comprising a sending side and said receiving side that are different sides connected via a transmission path, comprising:
- a counter for counting a number of packets received at the receiving side within a predetermined time period, and a count value handler for handling a count value determined by said counter in a procedure for determining a packet drop indicator;
- and a trigger message response element for determining said time period on the basis of trigger messages received successively by said receiving side.
