Abstract

An instant messaging service is provided using short message service (SMS) messages as the underlying transport layer. A user having a phone to which an MSISDN is assigned can use another entity to generate messages to be transmitted as if they originated from the phone. The SMS message is delivered to the second party'"'"'s phone as per a normal SMS message and a copy of the SMS message can also be delivered to the sender'"'"'s phone to provide a full conversation history on all devices. The entity can also be used to receive SMS messages, in which case, delivery of SMS messages to the phone to which the MSISDN is assigned can be suspend to avoid a duplicate notification of incoming messages.

Claims

1. A method for distributing messages by a network messaging center, comprising:

receiving a message from a first entity, associated with a first Mobile Subscriber Integrated Services Digital Network Number (MSISDN), addressed to a second MSISDN;

transmitting the received message to the second MSISDN; and

forwarding a copy of the received message to a second entity associated with the first MSISDN.

2. The method of claim 1, wherein:

the first entity is a device to which the first MSISDN has been assigned; and

the second entity is an active address book associated with the first MSISDN.

3. The method of claim 1, wherein:

the first entity is an active address book associated with the first MSISDN; and

the second entity is a device to which the first MSISDN has been assigned.

4. The method of claim 3, further comprising modifying the copy of the received message to indicate the first MSISDN as the sender.

5. The method of claim 1, wherein the step of forwarding the copy of the received message is performed in response to determining that a suspend delivery condition is not active.

6. The method of claim 1, further comprising the step of buffering the copy of the received message prior to forwarding the copy to the second entity.

7. The method of claim 6, wherein the step of buffering is performed in response to determining that a suspend delivery condition is active.

8. The method of claim 1, further comprising the step of determining a suspend delivery condition to be active in accordance with activity associated with at least one of the first and second entities.

9. The method of claim 8, wherein the suspend delivery condition applies to all messages addressed to the first MSISDN.

10. The method of claim 8, wherein the suspend delivery condition applies to all messages associated with the second MSISDN.

11. A method for distributing messages by a network messaging center, comprising:

receiving a message from a first Mobile Subscriber Integrated Services Digital Network Number (MSISDN) addressed to a second MSISDN;

forwarding the received message to an entity associated with the second MSISDN; and

withholding transmission of the received message to a device to which the second MSISDN has been assigned, in response to determining a suspend delivery condition associated with the second MSISDN is active.

12. The method of claim 11, wherein the entity associated with the second MSISDN is an active address book.

13. The method of claim 11, further comprising the step of buffering the received message for later delivery.

14. The method of claim 13, further comprising the step of transmitting all buffered messages to the device to which the second MSISDN has been assigned.

15. The method of claim 11, further comprising the step of transmitting the received message to the device to which the second MSISDN has been assigned, in response to determining the suspend delivery condition is not active.

16. The method of claim 15, wherein the step of transmitting includes retrieving the withheld message from a storage.

17. A Short Message Service Center (SMS-C) comprising:

an SMS-C interface for sending messages to and receiving messages from a second SMS-C;

a mobile device interface for sending messages to and receiving messages from a mobile device to which a Mobile Subscriber Integrated Services Digital Network Number (MSISDN) has been assigned;

an active address book interface for sending messages to and receiving messages from an entity associated with the MSISDN; and

a processor for receiving a message over one of the SMS-C interface, the mobile device interface, and the active address book interface and for forwarding the received message to the other two interfaces.

18. The SMS-C of claim 17, further comprising:

a buffer for queuing messages forwarded to the mobile device interface.

19. The SMS-C of claim 17, wherein the processor includes a delivery suspension engine for determining a suspend delivery condition associated with the MSISDN is active, and for forwarding the received message to a buffer in response to the determination.

20. The SMS-C of claim 17, wherein the processor includes a modification engine for modifying the received message prior to forwarding the message to the mobile device interface.
