Method and apparatus for determining a telephone number for accessing a target entity
DC CAFCFirst Claim
1. A method of determining a telephone number for contacting a target entity identified by a number string, said method comprising the steps of:
- (a)—
storing in the domain name system (DNS) of the Internet records each associated with a corresponding domain name and holding a telephone number of an entity associated with the domain name, each said domain name being related to a respective number string from which it can be derived by a process including parsing at least a substantial portion of the number string into at least a part of said domain name;
(b)—
applying said process to the said number string identifying the target entity whereby to form the related domain name; and
(c)—
supplying the domain name formed in step (b) to the DNS to retrieve the telephone number held in the corresponding said record.

Abstract
Service resource items (49) for use in call setup in a telephone system are held on servers (58) that are connected to a computer network which is logically distinct from the telephone system infrastructure; this computer network may, for example, make use of the Internet. Each service resource item (49) is locatable on the network at a corresponding URI and is associated with a particular telephone number. A mapping is provided between telephone numbers and the URIs of associated service resource items. When it is desired to access a service resource item (49) associated with a particular telephone number, this mapping is used to retrieve the corresponding URI (step 55) which is then used to access the desired service resource item (56, 57, 59).

4. A method of determining a telephone number for contacting a target entity, said method comprising the steps of:
-
(a)—
forming, from a number string identifying the target entity, a domain name by a process including parsing at least a substantial portion of the number string into at least a part of said domain name;(b)—
(supplying the domain name formed in step (a) to the domain name system of the Internet and receiving back from the domain name system a resource record including a telephone number. - View Dependent Claims (5, 6)

7. A method of determining a telephone number for contacting a target entity identified by a number string, said method comprising the steps of:
-
(a)—
storing in a DNS-type distributed database system, records each associated with a corresponding domain name and each holding a telephone number of an entity associated with the domain name, each said domain name being related to a respective number string from which it can be derived by a process including parsing at least a substantial portion of the number string into at least a part of said domain name;(b)—
applying said process to the said number string identifying the target entity whereby to form the related domain name; and(c)—
supplying the domain name formed in step (b) to the DNS-type distributed database to retrieve the telephone number held in the corresponding said record. - View Dependent Claims (8)

- 9. A server of the domain name system of the Internet, the server holding at least one resource record that provides a mapping from a domain name to a telephone number of a party associated with the domain name, at least a substantial portion of the domain name being in the form of a number string that has been parsed into plural domain-name labels.
- 11. A DNS-type distributed database system holding at least one resource record that provides a mapping from a domain name to a telephone number of a party associated with the domain name, at least a substantial portion of the domain name being in the form of a number string that has been parsed into plural domain-name labels.
