Abstract

A message distribution center (MDC) is interposed between content providers and a wireless carrier to subjectively examine and direct messages via SMTP based on desired rules (e.g., non-peak hours, paying subscribers only, etc.) using standard SMTP Gateway and other well-known protocols. The MDC includes an individual queue for each subscriber, and the provider is informed through conventional SMTP protocol messages that the short message has been accepted. If the carrier has specifically disallowed service for a particular MIN (e.g., in the case of churning), then the content provider is informed through an SMTP interchange that the recipient is invalid. An MDC provides a single mechanism for interacting with subscribers of multiple carriers, regardless of each carrier'"'"'s underlying infrastructure. For the carrier, an MDC can protect their SS7 network by intelligently throttling messages and configuring message delivery parameters to be more network friendly. An MDC can receive outside a relevant wireless network recipient handset presence information. In the disclosed embodiment, a content provider communicates with the MDC using SMTP protocol messages, and the MDC communicates with wireless carriers preferably using RMI/SMPP techniques.

Claims

1. A message distribution center, comprising:

a receiver to receive a given short message from a short message source device;

a plurality of subscriber queues storing short messages, including one of said plurality of subscriber queues storing said given short message, before delivery to a wireless carrier'"'"'s subscriber message delivery network;

an automatic deletion module to automatically delete a short message from at least one of said plurality of subscriber queues when a maximum threshold associated with said one of said plurality of subscriber queues is exceeded, said maximum threshold being determined according to a delivery statistic; and

a transmitter to transmit said given short message to said wireless carrier'"'"'s subscriber message delivery network.

2. The message distribution center according to claim 1, further comprising:

an assignment module to individually assign each of said plurality of subscriber queues a maximum number of short messages that each of said plurality of subscriber queues can store.

3. The message distribution center according to claim 1, further comprising:

at least one of an RMI communication interface and an SMPP communication interface to transmit said queued short message.

4. The message distribution center according to claim 1, wherein:

said plurality of subscriber queues each correspond to a different subscriber in said wireless carrier'"'"'s subscriber message delivery network.

5. The message distribution center according to claim 1, wherein:

each of said plurality of subscriber queues operates in a first in-first out fashion.

6. The message distribution center according to claim 1, wherein:

said wireless carrier'"'"'s subscriber message delivery network is a wireless intelligent network (WIN).

7. A method of delivering a short message with a message distribution center, comprising:

receiving a given short message from a short message source device;

storing said given short message in at least one of a plurality of subscriber queues before delivery to a wireless carrier'"'"'s subscriber message delivery network;

automatically deleting a short message from at least one of said plurality of subscriber queues when a maximum threshold associated with said one of said plurality of subscriber queues is exceeded, said maximum threshold being determined according to a delivery statistic; and

transmitting said given short message to said wireless carrier'"'"'s subscriber message delivery network.

8. The method of delivering a short message with a message distribution center according to claim 7, further comprising:

individually assigning to each of said plurality of subscriber queues, with an assignment module, a maximum number of short messages that each of said plurality of subscriber queues can store.

9. The method of delivering a short message with a message distribution center according to claim 7, further comprising:

transmitting said queued short message with at least one of an RMI communication interface and an SMPP communication interface.

10. The method of delivering a short message with a message distribution center according to claim 7, wherein:

said plurality of subscriber queues each corresponding to a different subscriber device in said wireless carrier'"'"'s subscriber message delivery network.

11. The method of delivering a short message with a message distribution center according to claim 7, further comprising:

operating each of said plurality of subscriber queues in a first in-first out fashion.

12. The method of delivering a short message with a message distribution center according to claim 7, wherein:

said wireless carrier'"'"'s subscriber message delivery network is a wireless intelligent network (WIN).
