Methods, systems, and computer program products for using an E.164 number (ENUM) database for message service message routing resolution among 2G and subsequent generation network systems

A method for message service message routing resolution among second generation (2G) and subsequent generation network systems, the method comprising:

• receiving a message including message service content and a 2G message recipient identifier;
• determining whether subscriber preference information regarding delivery of the message via a 2G network or a subsequent generation network exists;
• querying an ENUM database, wherein a response to the query includes an indicator indicating availability of a subscriber at one or more network delivery addresses, and determining that both 2G and subsequent generation network delivery addresses are available for the subscriber, determining that both 2G and subsequent generation network delivery addresses are available for the subscriber includes determining that the subsequent generation network address is provisioned in the ENUM database and that the recipient is currently available at the 2G and subsequent generation network delivery addresses;
• and
• in response to determining that the subscriber preference information exists, delivering the message service content to a recipient via at least one of the 2G and the subsequent generation network in accordance with the subscriber preference information, wherein delivering the message service content in accordance with the subscriber preference information includes delivering the subscriber content via the 2G network if the subscriber preference information indicates that the subscriber prefers 2G delivery over 3G delivery.

A system for messaging service message routing resolution among second generation (2G) and subsequent generation network systems, the system comprising:

• an E.164 Number (ENUM) database for storing information for translating 2G subscriber identifiers to 3G addresses, wherein the ENUM database is configured to respond to queries with a response including an indicator indicating availability of a subscriber at one or more network delivery addresses;
• and
• a 2G and subsequent generation message service gateway operatively associated with the ENUM database for receiving message including message service content and a 2G recipient identifier, for querying the ENUM database using the 2G recipient identifier, for receiving a response from the ENUM database, for determining, based on the response, unavailability of a subsequent generation network delivery address for the recipient or unavailability of the recipient via any subsequent generation network delivery address provisioned for the recipient with the ENUM database, and for attempting, in response to determining the unavailability of a subsequent generation network delivery address for the recipient in the ENUM database or the unavailability of the recipient via any subsequent generation network delivery addresses provisioned for the recipient in the ENUM database, attempting to deliver delivering the message service content to the recipient via a 2G network.

A non-transitory computer program product comprising computer-executable instructions embodied in a computer-readable medium for performing steps comprising:

• receiving a message including message service message content and a 2G message recipient identifier;
• querying an E.164 number (ENUM) database using the 2G message recipient identifier;
• receiving a response from the ENUM database, wherein the response includes an indicator indicating availability of the recipient at one or more network delivery addresses;
• determining, based on the response, unavailability of the recipient at a subsequent generation network delivery address provisioned for the recipient in the ENUM database or unavailability of the recipient via any subsequent generation network delivery addresses provisioned for the recipient in the ENUM database;
• and
• in response to determining the unavailability of a subsequent generation network delivery address provisioned for the recipient in the ENUM database or the unavailability of the recipient any subsequent generation network delivery addresses provisioned for the recipient in the ENUM database, attempting to deliver the message service content to the recipient via a 2G network.

• and
• in response to determining that the subscriber preference information exists, delivering the message service content to a recipient via at least one of the 2G and the subsequent generation network in accordance with the subscriber preference information, wherein delivering the message service content in accordance with the subscriber preference information includes delivering the subscriber content via the 2G network if the subscriber preference information indicates that the subscriber prefers 2G delivery over 3G delivery.
