Abstract

A sender can create and send a message that can be delivered to recipients with SMS-enabled wireless stations regardless of the other communication capabilities of the wireless stations and the network or network service providers of the recipients. The sender creates a voice message and sends the message to a message server, which stores the message in an interactive voice response (IVR) system. An SMS notification is sent to the recipient and includes instructions for accessing the voice message from the IVR system. The recipient views the SMS notification and accesses the IVR system. After entering a password or otherwise authenticating the recipient or the recipient wireless station, the recipient retrieves the message from the IVR system. If it is not known whether the recipient has an SMS-enabled wireless station, the message server initiates attempts to send SMS notifications using multiple SMS message generation mechanisms.

Claims

1. In a wireless communication system, a method of initiating delivery of a voice message to a recipient wireless station, comprising:

receiving an instant voice message at a message server from a sender device, the voice message designating a recipient;

storing the instant voice message in an interactive voice response (IVR) system associated with the message server;

14. The method of claim 1, wherein initiating transmission of the SMS notification and transmitting the stored instant voice message from the IVR system to the recipient wireless station are conducted without requiring the recipient wireless station to have any particular communication capabilities for receiving voice messages other than being SMS-enabled.

15. The method of claim 1, wherein initiating transmission of the SMS notification and transmitting the stored instant voice message from the IVR system to the recipient wireless station are conducted without requiring the recipient wireless station to operate on the same wireless network as the sender device.

16. In a server of a wireless network, a method of initiating delivery of an instant voice message to a recipient wireless station, comprising:

in response to an instant voice message addressed to a designated recipient being stored in an interactive voice response (IVR) system, determining whether a database associated with the server indicates whether a recipient wireless station associated with the designated recipient is enabled for Short Message Service (SMS) messages;

if it is determined that the database indicates that the recipient wireless station is enabled for SMS messages, transmitting an SMS message to the recipient wireless station, the SMS message including instructions for accessing the instant voice message stored in the IVR system; and

if it is determined that the database does not indicate whether the recipient wireless station is enabled for SMS messages;

communicating with one or more interfaces to determine whether the recipient wireless station is capable of receiving SMS messages from any of the one or more interfaces; and

if it is determined that the recipient wireless station is capable of receiving SMS messages from one of the one or more interfaces, transmitting an SMS message to the recipient from said one of the one or more interfaces, the SMS message including instructions for accessing the instant voice message stored in the IVR system.

17. The method of claim 16, wherein:

the one or more interfaces includes at least two interfaces; and

communicating with the one or more interfaces comprises communicating with the at least two interfaces in parallel.

18. The method of claim 16, wherein:

the one or more interfaces includes at least two interfaces; and

communicating with the one or more interfaces comprises communicating with the at least two interfaces in sequence.

19. The method of claim 16, wherein the one or more interfaces includes a native SMS gateway, a HyperText Transfer Protocol (HTTP) SMS gateway and a SMS controller.

20. The method of claim 16, further comprising, if it is determined that the database indicates that the recipient wireless station is not enabled for SMS messages, transmitting an error message to a sender device associated with a sender of the instant voice message.

21. The method of claim 16, further comprising, if it is determined that the database does not indicate whether the recipient wireless station is enabled for SMS messages, updating the database to indicate whether the recipient wireless station is enabled for SMS messages after communicating with one or more interfaces.

22. In a wireless station that operates in a wireless network, a method of accessing an instant voice message, comprising:

receiving a Short Message Service (SMS) message that includes instructions for accessing an instant voice message stored in an interactive voice response (IVR) system, wherein the instant voice message is associated with a first mobile directory number that is provided by a sender of the instant voice message;
