Abstract
Abstract In the Intelligent Networks environment, where multiple Service Providers and multi-Vendor equipment are involved in new service offering, the risk of overloading the network elements are real and managing the traffic is a challenge. Network traffic overloads could result from equipment failures, major equipment outages, or widespread loads above engineered levels. To solve the problem of network traffic overload, a Mediation Point (MP) is connected to a group of service control points (SCP). The MP includes control feature to balance the load and manage the overload controls for the multiple SCPs that are deployed in load sharing mode in the network.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
123 words
In an intelligent telecommunications network having a plurality of service control points (SCPs) forming a load sharing group, a method for managing traffic consisting of queries to the load sharing group, comprising the steps of: maintaining respective controls lists for the plurality of SCPs, each controls list identifies controls which are active at the corresponding SCP; sending a query intended for the load sharing group to a mediation point (MP); and selecting, by the MP which has access to the respective controls lists, a particular SCP of the plurality of SCPs for which the controls list of the particular SCP does not identify a control relating to the query as being active; and sending, from the MP, the query to the particular SCP.
Claim 2
Dependent Claim
123 words
In an intelligent telecommunications network having a plurality of service control points (SCPs) forming a load sharing group, a method for managing traffic consisting of queries to the load sharing group, comprising the steps of: maintaining respective controls lists for the plurality of SCPs, each controls list identifies controls which are active at the corresponding SCP; sending a query intended for the load sharing group to a mediation point (MP); and selecting, by the MP which has access to the respective controls lists, a particular SCP of the plurality of SCPs for which the controls list of the particular SCP does not identify a control relating to the query as being active; and sending, from the MP, the query to the particular SCP.
Claim 3
Dependent Claim
29 words
A method as claimed in claim 1, comprising discarding, responsive to an active control relating to the query being identified in each controls list, the query by the MP.
Claim 4
Dependent Claim
67 words
A method as claimed in claim 1, comprising the steps of: generating a new control by any one SCP of the plurality of SCPs in the load sharing group; sending, by the any one SCP, an add control signal which identifies the new control to the MP; and updating, by the MP, the controls list corresponding to the any one SCP to add the identified new control.
Claim 5
Dependent Claim
37 words
A method as claimed in claim 3, wherein the step of generating the new control includes receiving, by the any one SCP, the query which results in the any one SCP reaching a predetermined level of congestion.
Claim 6
Dependent Claim
59 words
A method as claimed in claim 4, comprising the steps of: sending, by the any one SCP of the plurality of SCPs in the load sharing group, a remove control signal which identifies an existing control to the MP; and updating, by the MP, the controls list corresponding to the any one SCP to remove the identified existing control.
Claim 7
Dependent Claim
39 words
A method as claimed in claim 5, wherein individual controls in the controls lists are identified by a global title address and translation type, and each query includes respective indications for the global title address and the translation type.
Claim 8
Dependent Claim
59 words
A method as claimed in claim 6, wherein the any one SCP is overloaded when the predetermined congestion level which is associated with the global title address and the translation type indicated in the received query is reached; and the add control signal includes an identifier of the any one SCP, the global title address and the translation type.
Claim 9
Dependent Claim
24 words
A method as claimed in claim 7, wherein the add control signal indicates one or more levels of congestion on the any one SCP.
Claim 10
Independent Claim
122 words
A system for managing traffic consisting of queries to a load sharing group of service control points (SCPs) in an intelligent telecommunications network, comprising: a plurality of SCPs in the load sharing group; and a mediation point (MP) communicatively coupled to the plurality of SCPs, wherein the MP includes: respective controls lists for the plurality of SCPs, each controls list identifies controls which are active at the corresponding SCP; means for receiving a query intended for the load sharing group; means for selecting a particular SCP of the plurality of SCPs for which the controls list of the particular SCP does not identify a control relating to the query as being active; and means for sending the query to the particular SCP.
Claim 11
Independent Claim
122 words
A system for managing traffic consisting of queries to a load sharing group of service control points (SCPs) in an intelligent telecommunications network, comprising: a plurality of SCPs in the load sharing group; and a mediation point (MP) communicatively coupled to the plurality of SCPs, wherein the MP includes: respective controls lists for the plurality of SCPs, each controls list identifies controls which are active at the corresponding SCP; means for receiving a query intended for the load sharing group; means for selecting a particular SCP of the plurality of SCPs for which the controls list of the particular SCP does not identify a control relating to the query as being active; and means for sending the query to the particular SCP.
Claim 12
Dependent Claim
31 words
A system as claimed in claim 9, wherein the MP includes means, responsive to an active control corresponding to the query being identified in each controls list, for discarding the query.
Claim 13
Dependent Claim
67 words
A system as claimed in claim 9, wherein each SCP of the plurality of SCPs includes means for generating a new control, and means for sending an add control signal which identifies the new control to the MP; and wherein the MP includes means for updating the controls list corresponding to the SCP from which the add control signal is received, to add the identified new control.
Claim 14
Dependent Claim
35 words
A system as claimed in claim 11, wherein the means for generating the new control, in each SCP, includes means for receiving the query which results in that SCP reaching a predetermined level of congestion.
Claim 15
Dependent Claim
60 words
A system as claimed in claim 12, wherein each SCP of the plurality of SCPs includes means for sending a remove control signal which identifies an existing control to the MP; and wherein the MP includes means for updating the controls list corresponding to the SCP from which the remove control signal is received, to remove the identified existing control.
Claim 16
Dependent Claim
39 words
A system as claimed in claim 13, wherein individual controls in the controls lists are identified by a global title address and translation type, and each query includes respective indications for the global title address and the translation type.
Claim 17
Dependent Claim
58 words
A system as claimed in claim 14, wherein any one SCP becomes overloaded when the predetermined congestion level which is associated with the global title address and the translation type indicated in the received query is reached; and the add control signal includes an address of the any one SCP, the global title address and the translation type.
Claim 18
Dependent Claim
24 words
A system as claimed in claim 15, wherein the add control signal indicates one or more levels of congestion on the any one SCP.
