Abstract

A communication system providing telephony communication across combined circuit switched and packet switched networks, such as a telephone network and the Internet, which are connectable to terminals, such as telephones and computers, for selective communication therebetween. The communication system includes an authorization and account control object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an information retrieval object in the packet switched network.

Claims

1. In a hybrid communications network comprising a circuit switched network and a packet-switched network, wherein the hybrid communications network comprises at least one session control object of a first service provider, a method for establishing a given communication session through the session control object comprising:

at a unitary logical object of a second service provider different than the first service provider, receiving a request to initiate the given communication session between a calling terminal and a called terminal, the calling terminal communicably coupled to at least one network element of the first service provider, the request identifying a user account associated with the calling terminal and including an address of the called terminal, the unitary logical object including a unitary logical database;

at the unitary logical object, authenticating an identity of a user of the calling terminal by accessing authentication information in the unitary logical database, checking a status of the user account by accessing account status information in the unitary logical database, and determining whether to permit establishment of the given communication session through the session control object based on the status of the user account;

from the unitary logical object, sending a response signal indicating whether establishment of the given communication session through the session control object is permitted; and

wherein the unitary logical object is distributed over multiple physical systems.

2. The method of claim 1, wherein each of the multiple physical systems includes an instance of the unitary logical object.

3. The method of claim 2, wherein the unitary logical object stores a plurality of user accounts, and each instance of the unitary logical object corresponds to a subgroup of the plurality of user accounts.

4. The method of claim 3, wherein the authenticating the identity of the user, checking the status of the user account, and determining whether to permit establishment of the given communication session includes determining the instance of the unitary logical object storing the user account associated with the calling terminal.

5. The method of claim 1, wherein the request to initiate the given communication session is sent from the session control object to the unitary logical object.

6. The method of claim 1, wherein the response signal indicating that the given communication session is authorized is sent from the unitary logical object to the session control object.

7. The method of claim 1, further comprising:

receiving usage information associated with the given communication session at the unitary logical object; and

logging the usage information in the unitary logical database.

8. The method of claim 7, further comprising decrementing a balance of the user account in the unitary logical database based on the usage information.

9. The method of claim 8, wherein the usage information comprises at least one of amount of usage or pricing of usage.

10. The method of claim 1, wherein the account status information in the unitary logical database includes information indicating whether a communications session is in progress that is associated with the user account, and the determining whether to permit establishment of the given communication session is based on whether there is already another communications session that is in progress that is associated with the user account.

11. The method of claim 1, wherein the account status information in the unitary logical database includes an available account balance of the user account, and the determining whether to permit establishment of the given communication session includes determining whether an available account balance of the user account permits the given communication session to be established.

12. The method of claim 1,

wherein the authenticating the identity of the user of the calling terminal includes receiving a password from the user and verifying that the password corresponds to the authentication information in the unitary logical database.

13. The method of claim 1,

wherein the account status information includes information indicating billing arrangements associated with the user account.

14. In a hybrid communications network comprising a circuit switched network and a packet-switched network, wherein the hybrid communications network comprises at least one session control object in a first network domain operated by a first service provider, a method for establishing a given communications session through the session control object comprising:

at an authorization and usage recording object in a second network domain operated by a second service provider different than the first service provider, receiving a request to initiate the given communication session between a calling terminal and a called terminal, wherein the calling terminal is communicably coupled to at least one network element in the first network domain, and wherein the request identifies a user account associated with the calling terminal and includes an address of the called terminal, the authorization and usage recording object including a unitary logical database that contains account status information associated with user accounts;

at the authorization and usage recording object, determining whether to authorize the establishment of the given communication session through the session control object based on the account status information in the unitary logical database that is associated with the user account;

from the authorization and usage recording object, sending a response signal indicating whether establishment of the given communication session through the session control object is authorized; and

at the authorization and usage recording object, updating the account status information that is associated with the user account in the unitary logical database based on usage information pertaining to the given communication session;

wherein the authorization and usage recording object comprises a single logical object distributed over one or more physical systems.

15. The method of claim 14, further comprising:

at the authorization and usage recording object, receiving from the session control object the usage information pertaining to the given communication session, which includes at least one of;

initiation of the given communication session, progress of the given communication session, pricing of the given communication session and termination of the given communication session.

16. The method of claim 14, wherein the request to initiate the given communication session is sent from the session control object to the authorization and usage recording object.

17. The method of claim 14, wherein the response signal indicating that establishment of the given communication session is authorized is sent from the authorization and usage recording object to the session control object.

18. The method of claim 14, wherein the account status information in the unitary logical database includes information indicating whether a communications session is in progress that is associated with the user account, and the determining whether to permit establishment of the given communication session is based on whether there is already another communications session that is in progress that is associated with the user account.

19. The method of claim 14, wherein the account status information in the unitary logical database includes an available account balance of the user account, and the determining whether to authorize establishment of the given communication session includes determining whether an available account balance of the user account permits the given communication session to be established.

20. The method of claim 14, wherein each of the multiple physical systems includes an instance of the authorization and usage recording object.

21. The method of claim 14, further comprising:

at the authorization and usage recording object, authenticating the identity of a user associated with the calling terminal by accessing authentication information in the unitary logical database.
