Abstract
Abstract A method of volume screening signalling messages in a communications signalling system, in which control orders from a centralized control are distributed so as to provide equitable volume screening of selected signalling messages being sent over each available communications link of a plurality of links within link sets that interconnect signal transfer points (STPs) of the system. This is achieved by dynamically apportioning the acceptance rate of the selected signalling messages from each available link, in the same proportion as that of the total signalling messages being sent over that available link.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
A method of volume screening signalling messages at mated pairs of signal transfer points interconnected with other mated pairs by link sets in a telecommunication system, comprising the steps of: dividing the signalling messages sent from each signal transfer point of one mated pair to those of another mated pair over links of the link sets; dynamically apportioning the signalling messages equally amongst available links within each link set; selecting some of the signalling messages in accordance with volume-screening parameters; limiting the rate at which the selected signalling messages are accepted by said another mated pair; and dynamically apportioning the acceptance rate of the selected signalling messages from each available link, in the same proportion as that of the total signalling messages sent over that available link.
Claim 2
Independent Claim
127 words
A method of volume screening signalling messages at mated pairs of signal transfer points interconnected with other mated pairs by link sets in a telecommunication system, comprising the steps of: dividing the signalling messages sent from each signal transfer point of one mated pair to those of another mated pair over links of the link sets; dynamically apportioning the signalling messages equally amongst available links within each link set; selecting some of the signalling messages in accordance with volume-screening parameters; limiting the rate at which the selected signalling messages are accepted by said another mated pair; and dynamically apportioning the acceptance rate of the selected signalling messages from each available link, in the same proportion as that of the total signalling messages sent over that available link.
Claim 3
Dependent Claim
95 words
A method of volume screening signalling messages in accordance with claim 1, further comprising: dividing said signalling messages sent from said one mated pair equally between its signal transfer points; dynamically apportioning the acceptance rate of the selected signalling messages at each signal transfer point, in the same proportion as that of the total signalling messages sent to that signal transfer point; and dynamically apportioning the acceptance rate of the selected signalling messages from each available link set, in the same proportion as that of the total signalling messages sent over that available link set.
Claim 4
Dependent Claim
81 words
A method of volume screening signalling messages in accordance with claim 2, in which the maximum average acceptance rate of the selected signalling messages is one message per gapping interval, further comprising: setting the gapping interval for each link set to be inversely proportional to the proportion of the total signalling messages sent over that link set; and setting the gapping interval for each link to be inversely proportional to the proportion of the total signalling messages sent over that link.
Claim 5
Dependent Claim
64 words
A method of volume screening signalling messages in accordance with claim 2, in which the signal transfer points are interconnected by identical link sets, further comprising: apportioning the acceptance rate of the selected signalling messages in a successive manner equally between the signal transfer points of said another mated pair, equally amongst the link sets, and equally amongst the links of each link set.
Claim 6
Dependent Claim
41 words
A method of volume screening signalling messages in accordance with claim 4, further comprising: dynamically reapportioning the acceptance rate of the selected signalling messages in response to changes in the volume of signalling messages being received by said another mated pair.
Claim 7
Independent Claim
88 words
A method of volume screening signalling messages at signal points in a telecommunication system, comprising the steps of: receiving signalling messages at each signal point over links of link sets, dynamically apportioning the received signalling messages equally amongst available links within each link set; selecting at least some of the signalling messages in accordance with volume-screening parameters; and dynamically apportioning the rate the selected signalling messages are accepted from each available link, in the same proportion as that of the total signalling messages sent over that available link.
Claim 8
Independent Claim
88 words
A method of volume screening signalling messages at signal points in a telecommunication system, comprising the steps of: receiving signalling messages at each signal point over links of link sets, dynamically apportioning the received signalling messages equally amongst available links within each link set; selecting at least some of the signalling messages in accordance with volume-screening parameters; and dynamically apportioning the rate the selected signalling messages are accepted from each available link, in the same proportion as that of the total signalling messages sent over that available link.
Claim 9
Dependent Claim
46 words
A method of volume screening signalling messages in accordance with claim 6, further comprising: dynamically apportioning the acceptance rate of the selected signalling messages from each available link set in the same proportion as that of the total signalling messages sent over that available link set.
