Packet switched radio channel traffic supervision
First Claim
1. In a telecommunication system comprising at least one packet radio channel and a plurality of transceiving stations, each of said transceiving stations capable of transmitting packet calls comprising a plurality of data packets on at least one packet radio channel, a method of supervising traffic on the at least one radio channel, said method comprising the steps of:
- a) receiving periodic packet reports associated with at least one packet call on the packet radio channel, said packet report including information on a number of frames included in the packet call, a packet identifier for identifying the packet call associated with the packet report and a time stamp indicating when the packet call was placed in a transmission buffer;
b) calculating the size of the packet call in time in response to the information on the number of frames;
c) calculating the difference between the time the packet report was received and the time the packet call was placed in the transmission buffer;
d) calculating the time lapse since a previous packet report having the same packet identifier was received; and
e) utilizing the calculations from steps b) -d), to calculate an estimated average data traffic for the packet call on the at least one packet radio channel.

Abstract
A method and system for packet switched radio channel (PRCH) traffic supervision is disclosed. A PRCH supervision function receives a packet report for each data packet transmitted on the PRCH. The PRCH supervision function calculates an estimate of average data traffic for each packet call on the PRCH, an estimate of average data traffic on the PRCH and an estimate of the average packet delay on the PRCH. The calculations may be done for the uplink and downlink of the PRCH separately, or, as values for the combined uplink and downlink of the PRCH. The results of the calculations may then be used to determine if a packet call should be admitted to the PRCH or if a packet call should be expelled from the PRCH.

12. In a telecommunication system comprising at least one packet radio channel and a plurality of transceiving stations, each of said transceiving stations capable of transmitting and receiving packet calls on the at least one packet radio channel, a method of supervising traffic on the at least one radio channel, said method comprising the steps of:
-
a) receiving periodic packet reports associated with a packet call on the packet radio channel, said packet report including information on a number of frames a for the associated packet call, a packet identifier for identifying the packet call associated with the packet report and a time stamp indicating when the associated packet call was placed in a transmission buffer; b) calculating the size of the packet call in time in response to the information on the number of frames; c) calculating the difference between the time the packet report was received and the time the data packet was placed in the transmission buffer; d) calculating the time lapse since a previous packet report having the same packet identifier was received; and e) utilizing the calculations from steps b)-d), to calculate an estimated average traffic delay for each individual packet call on the at least one packet radio channel upon receipt of each packet report.

-
a) receiving periodic packet reports associated with packet calls on the packet radio channel, said packet report including information on a number of frames included in the associated packet call, a packet identifier for identifying the packet call associated with the packet report and a time stamp indicating when the associated packet call was placed in a transmission buffer; b) calculating the size of the packet call in time in response to the number of frames; c) calculating the difference between the time the packet report was received and the time the packet call was placed in the transmission buffer; d) calculating the time lapse since a previous packet report having the same packet identifier was received; and e) utilizing the calculations from steps b)-d), to calculate an estimated average data traffic delay for each individual packet call on the at least one packet radio channel upon receipt of each packet report.

14. An apparatus for controlling traffic on a packet radio channel, said apparatus comprising:
-
means for receiving periodic packet reports on a packet call from a network protocol stack, the packet report including a packet identifier, a number of frames comprising the packet call and a time stamp indicating when the packet call was placed in a transmission buffer; an admission control function for controlling admission of packet calls to the packet radio channel; a congestion control function for controlling expulsion of packet calls from the packet radio channel; and a packet radio channel traffic supervisor function responsive to the number of frames and the time stamp in each received packet report for updating system traffic status and controlling the admission control function and the congestion control function in accordance with the updated system traffic status. - View Dependent Claims (15, 16, 17, 18, 19)
