Abstract
Abstract A system allocates data links between a switch and a database for data transactions in a telecommunications network. The data links between the switch and the database carry the transaction data for providing routing, card verification, address translation information, etc. by the database. The Flexible Link Selection Algorithm provides for accessing the data links using the round-robin method, wherein each data link is accessed sequentially to transport the data to and from the database. Alternatively, the Flexible Link Selection Algorithm provides for accessing the data links using dynamic allocation based on the least cost routing between the switch and the database. In the latter mode, the switch uses the least "expensive" database, i.e., database having the least cost routing between the switch and the database, until the volume of data transactions in the data links associated with that database exceeds a predetermined threshold level. If the threshold level is exceeded, the next least "expensive" database is selected, and its data links are utilized used to carry the data transactions between the database and the switch.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
266 words
A telecommunications system for selecting the least cost routing of a database transaction, comprising: at least two intelligent platform means for providing information associated with the transaction, wherein each intelligent platform means includes substantially identical information required for processing the transaction; each intelligent platform means having first ends of at least two data links connected thereto for selectively carrying information associated with the transaction; and a switch, communicatively coupled with the intelligent platform means via second connected ends of the data links for routing a telephone call through a network excluding the platform means, based on a result of the transaction, wherein the switch includes processing means for selecting a data link to an intelligent platform means based on a least cost of routing the database transaction between the switch and the intelligent platform means, the processing means further determining transaction traffic along each of the data links associated with a first selected platform means involving least cost routing, and (a) if the transaction traffic with the first platform means is below a preselected threshold on each data link of the selected platform means, selectively alternating data links for carrying transactions; (b) if the transaction traffic on one of the data links of the first platform means is above the preselected threshold, selectively switching transactions to the other data link, for as long as the threshold thereon is not exceeded; and (c) if the transaction traffic on both of the data links of the first platform means is above the preselected threshold, selectively switching transactions to the data links associated with a second intelligent platform means.
Claim 2
Dependent Claim
266 words
A telecommunications system for selecting the least cost routing of a database transaction, comprising: at least two intelligent platform means for providing information associated with the transaction, wherein each intelligent platform means includes substantially identical information required for processing the transaction; each intelligent platform means having first ends of at least two data links connected thereto for selectively carrying information associated with the transaction; and a switch, communicatively coupled with the intelligent platform means via second connected ends of the data links for routing a telephone call through a network excluding the platform means, based on a result of the transaction, wherein the switch includes processing means for selecting a data link to an intelligent platform means based on a least cost of routing the database transaction between the switch and the intelligent platform means, the processing means further determining transaction traffic along each of the data links associated with a first selected platform means involving least cost routing, and (a) if the transaction traffic with the first platform means is below a preselected threshold on each data link of the selected platform means, selectively alternating data links for carrying transactions; (b) if the transaction traffic on one of the data links of the first platform means is above the preselected threshold, selectively switching transactions to the other data link, for as long as the threshold thereon is not exceeded; and (c) if the transaction traffic on both of the data links of the first platform means is above the preselected threshold, selectively switching transactions to the data links associated with a second intelligent platform means.
Claim 3
Dependent Claim
39 words
The telecommunications system according to claim 1, wherein the processing means re-enables switched transaction communication back to the first intelligent platform means when the transaction traffic on one of the data links associated therewith falls below the preselected threshold.
Claim 4
Dependent Claim
237 words
A telecommunications method for selecting the least cost routing of a database transaction, comprising the steps: providing information associated with the transaction from, at least two intelligent platforms, substantially identical information required for processing the transaction being stored at each intelligent platform; providing at least two data links to each intelligent platform for selectively carrying information associated with the transaction; and communicatively coupling a switch with the intelligent platforms via the data links for routing a telephone call through a network excluding the platforms, based on a result of the transaction; selecting a data link to an intelligent platform based on a least cost of routing the database transaction between the switch and the intelligent platforms; determining transaction traffic along each of the data links associated with a first selected platform involving least cost routing, and (a) if the transaction traffic with the first platform is below a preselected threshold on each data link of the selected platform, selectively alternating data links for carrying transactions; (b) if the transaction traffic on one of the data links of the first platform is above the preselected threshold, selectively switching transactions to the other data link, for as long as the threshold thereon is not exceeded; and (c) if the transaction traffic on both of the data links of the first platform is above the preselected threshold, selectively switching transactions to the data links associated with a second intelligent platform.
Claim 5
