Abstract
LNP databases are made locally accessible to one or more CNAM SCP to avoid network traffic associated with LNP routing determinations required with the advent of providers local number portability. All CNAM service queries are routed to the one or more CNAM SCPs for processing. Service routing is determined from the local accessible LNP databases without additional network traffic associated with such routing determinations in conventional systems. Four classes of service provider are defined. Queries for telephone services are routed in accordance with the class of service provider.
Claims26
A system for reducing traffic in a telephone network while providing caller name identification (CNAM) service, comprising:
- a signaling transfer point (STP) to receive a CNAM query from a switch on which a called party is homed, wherein the CNAM query contains a calling party telephone number;
- a CNAM SCP to receive the CNAM query from the STP and to return CNAM information to the switch;
- a CNAM SCP coupled to the CNAM SCP;
- and
- a duplicate local number portability signal control point (LNP SCP) database accessible to the CNAM SCP, the CNAM SCP database containing a plurality of CNAM records, wherein each CNAM record, comprises:
- a telephone number;
- and
- a directory name corresponding to the telephone number, and
- wherein the duplicate LNP SCP database contains a plurality of global translation title (GTT) records, each GTT record, comprising:
- a telephone number;
- and
- a service routing corresponding to a network element that provides the CNAM service.
A method for providing caller name identification (CNAM) service comprising the steps of:
- receiving a CNAM query from a switch on which a called party is homed through an STP, wherein the CNAM query contains a calling party telephone number;
- creating a duplicate LNP database containing a plurality of LNP routing records;
- routing the query directly to a CNAM LNP SCP, which is coupled to the duplicate LNP database and a CNAM database;
- accessing the LNP database obtaining routing information for processing the CNAM query;
- and
- routing the CNAM query in accordance with the obtained routing information for processing to obtain CNAM information in response to the CNAM query.
A system for reducing network traffic in a telephone network providing caller name identification (CNAM) service comprising:
- a signaling transfer point (STP) to receive a CNAM query from a switch on which a called party is homed, wherein the CNAM query contains a calling party telephone number;
- a CNAM service control point (CNAM SCP) to receive the CNAM query from the STP and return CNAM information to the switch;
- and
- a CNAM LNP database accessible to the CNAM SCP that contains a plurality of LNP routing records that duplicate an existing LNP database, each LNP routing record, comprising:
- a telephone number;
- and
- a service routing corresponding to a network element that provides the CNAM service.
A method for providing caller name identification (CNAM) service comprising the steps of:
- receiving a CNAM query from a switch on which a called party is homed, wherein the CNAM query contains a calling party telephone number;
- accessing a duplicate CNAM LNP database coupled to a CNAM SCP, containing a plurality of LNP routing records, obtaining routing information for processing the CNAM query;
- and
- routing the CNAM query in accordance with the obtained routing information.
A system for providing a telephone service, comprising:
- a signaling transfer point for receiving a service request requesting the telephone service to be provided from a switch on which a called party is homed;
- a service SCP for receiving the service request from the signaling transfer point;
- a duplicate LNP database coupled to the service SCP for providing routing information based on identification information in the service request;
- and
- means for routing the service request to a network element that provides the telephone service in accordance with the routing information.
A method for providing CNAM service, comprising the steps of:
- receiving a CNAM service request from a switch on which a called party is homed;
- obtaining routing information to route the CNAM service request to a network element responsible for providing the CNAM service from a duplicate LNP database coupled to a CNAM SCP;
- routing the CNAM service request to the network element to obtain CNAM information;
- and
- sending the CNAM information to a caller ID display device to be displayed.
