Abstract
A method of processing congestion conditions of a MTP user part in the SS7 network is disclosed. According to the method, a congestion condition is identified, and information regarding the condition is transmitted in a MTP user part to an originating signaling point. The originating signaling point reduces traffic to be transmitted to the MTP user part of the congested destination, thereby preventing an interruption of service.

A method of processing congestion conditions of a MTP user part in a SS7 network, comprising:
- (a) defining a user part congested (UPC) message that indicates when congestion has occurred in a MTP user part of a destination signaling point;
- a MTP_STATUS primitive to reduce a number of the signaling messages to be transmitted to the congested MTP user part;
- (b) generating the UPC message, and transmitting the generated UPC message to an originating signaling point of the signaling message when a MTP of the destination signaling point recognizes congestion conditions of the MTP user part of the destination signaling point;
- and
- (c) generating the MTP_STATUS primitive, and transmitting the generated MTP_STATUS primitive to a MTP user part of the originating signaling point to request the MTP user part of the originating signaling point to reduce the number of the signaling messages to be transmitted to the congested MTP user part of the destination signaling point.
A method of processing congestion conditions of a MTP user part in a SS7 network, comprising:
- (a) informing an originating signaling point that congestion has occurred in a MTP user part of a destination signaling point for a signaling message when a MTP of the destination signaling point recognizes the congestion conditions of the MTP user part of the destination signaling point;
- and
- (b) reducing a number of signaling messages to be transmitted from a MTP of the originating signaling point to the MTP user part of the congested destination signaling point in response to a request for reduction from a corresponding MTP user part of the originating signaling point.
A message transfer part (MTP) user part signaling message used to indicate congestion of a destination signaling point to a origination signaling point in a common channel signaling network, comprising:
- a congestion level parameter, indicating a degree of congestion in the MTP user part;
- a user part identification parameter, identifying the congested MTP user part;
- a destination code, identifying a signaling point to which the congested MTP user part belongs;
- and
- a routing label, indicating information for the message to be routed.
A message transfer part (MTP) user part signaling message used to indicate congestion of a destination signaling point to an origination signaling point in a common channel signaling network, comprising:
- means for identifying a congestion level in a congestion level parameter indicating a degree of congestion in the MTP user part;
- means for identifying a user part indicating the congested MTP user part;
- means for identifying a destination code indicating a signaling point to which the congested MTP user part belongs;
- and
- means for setting a routing label indicating information for the message to be routed.
A method of reducing the number of signaling messages to be transmitted from an origination point to a congested destination point in a common signaling network, comprising:
- receiving a User Part Congested (UPC) signal from an adjacent signaling point;
- generating an MTP_STATUS primitive in accordance with parameters from the UPC signal;
- transmitting the MTP_STATUS primitive to a corresponding MTP user part to reduce a number of signaling messages to be transmitted to the congested destination point.
