Abstract

Abstract A telecommunications network has a target exchange (RNC 222 2 ) which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange (RNC 222 1 ). The source exchange controls at least some connections which utilize radio resources in the region supervised by the target exchange. The congestion message causes the source exchange to adjust at least one connection which it controls in the region supervised by the target exchange. In a first mode of the invention, the target exchange determines a selected connection to be adjusted in view of the congestion condition. In this first mode, the congestion message identifies the selected connection to be adjusted and further includes an adjustment value (e.g., power reduction value) for the selected connection to be adjusted. In a second mode of the invention, the congestion message includes an identification of a congested area (e.g., a cell) within the region supervised by the target exchange, as well as a severity value indicating a severity of the congestion in the congested area. The severity value can be indicative of a needed decrease in congestion in the congested area.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 79 words
A telecommunications network having a target exchange which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange, the source exchange controlling connections with mobile stations which utilize radio frequency resources in the region supervised by the target exchange, which congestion message causes the source exchange to adjust at least one connection with a mobile station which it controls in the region supervised by the target exchange.
Claim 2
Dependent Claim 79 words
A telecommunications network having a target exchange which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange, the source exchange controlling connections with mobile stations which utilize radio frequency resources in the region supervised by the target exchange, which congestion message causes the source exchange to adjust at least one connection with a mobile station which it controls in the region supervised by the target exchange.
Claim 3
Dependent Claim 36 words
The telecommunications network of claim 1 , wherein the target exchange determines a selected connection to be adjusted in view of the congestion condition, and wherein the congestion message identifies the selected connection to be adjusted.
Claim 4
Dependent Claim 22 words
The telecommunications network of claim 2 , wherein the congestion message includes an adjustment value for the selected connection to be adjusted.
Claim 5
Dependent Claim 20 words
The telecommunications network of claim 3 , wherein the adjustment value for the selected connection is a power reduction value.
Claim 6
Dependent Claim 18 words
The telecommunications network of claim 2 , wherein the congestion message identifies plural selected connections to be adjusted.
Claim 7
Dependent Claim 26 words
The telecommunications network of claim 1 , wherein the congestion message includes an identification of a congested area within the region supervised by the target exchange.
Claim 8
Dependent Claim 14 words
The telecommunications network of claim 6 , wherein the congested area is a cell.
Claim 9
Dependent Claim 26 words
The telecommunications network of claim 6 , wherein the congestion message includes an identification of plural congested areas within the region supervised by the target exchange.
Claim 10
Dependent Claim 25 words
The telecommunications network of claim 6 , wherein the congestion message includes a severity value indicating a severity of the congestion in the congested area.
Claim 11
Dependent Claim 23 words
The telecommunications network of claim 9 , wherein the severity value is indicative of a needed decrease in congestion in the congested area.
Claim 12
Independent Claim 90 words
A method of operating a telecommunications network comprising: determining, at a target exchange, a congestion condition in a region supervised by the target exchange; preparing and sending from the target exchange a congestion message to a source exchange, the source exchange controlling connections with mobile stations which utilize radio frequency resources in the region supervised by the target exchange; the source exchange responding to the congestion message to adjust at least one connection with a mobile station which the source exchange controls in the region supervised by the target exchange.
Claim 13
Independent Claim 90 words
A method of operating a telecommunications network comprising: determining, at a target exchange, a congestion condition in a region supervised by the target exchange; preparing and sending from the target exchange a congestion message to a source exchange, the source exchange controlling connections with mobile stations which utilize radio frequency resources in the region supervised by the target exchange; the source exchange responding to the congestion message to adjust at least one connection with a mobile station which the source exchange controls in the region supervised by the target exchange.
Claim 14
Dependent Claim 40 words
The method of claim 11 , further comprising: determining, at the target exchange, a selected connection to be adjusted in view of the congestion condition; and including in the congestion message an identification of the selected connection to be adjusted.
Claim 15
Dependent Claim 23 words
The method of claim 12 , further comprising including in the congestion message an adjustment value for the selected connection to be adjusted.
Claim 16
Dependent Claim 19 words
The method of claim 13 , wherein the adjustment value for the selected connection is a power reduction value.
Claim 17
Dependent Claim 18 words
The method of claim 12 , comprising including in the congestion message plural selected connections to be adjusted.
Claim 18
Dependent Claim 26 words
The method of claim 11 , comprising including in the congestion message an identification of a congested area within the region supervised by the target exchange.
Claim 19
Dependent Claim 13 words
The method of claim 16 , wherein the congested area is a cell.
Claim 20
Dependent Claim 27 words
The method of claim 16 , further comprising including in the congestion message an identification of plural congested areas within the region supervised by the target exchange.
Claim 21
Dependent Claim 26 words
The method of claim 16 , further comprising including in the congestion message a severity value indicating a severity of the congestion in the congested area.
Claim 22
Dependent Claim 22 words
The method of claim 19 , wherein the severity value is indicative of a needed decrease in congestion in the congested area.
