BACKGROUND

This invention, in general, relates to messaging services. More particularly, this invention relates to completing a call attempt made by a first party on a first network to a second party on a second network.

When a caller attempts to call a recipient on a network, multiple conditions may cause the call attempt to be terminated. For example, the call may be terminated due to a busy signal, an unanswered signal, an unreachable signal, manual termination by the caller, etc. The caller may thereafter wish to send a message to the recipient to complete the call attempt. There is a need for a messaging service to enable the caller to create and deliver messages including short messaging service (SMS) messages, voice SMS messages, multimedia messaging service (MMS) messages, and multimodal messages without making another call, or re-initiating the call to the recipient. Moreover, there is a need for a messaging service that enables the recipient to retrieve the message sent by the caller without difficulty.

The caller may manually terminate the call attempt on encountering the busy signal, the unanswered signal, the unreachable signal, etc. Even if a network provides some call attempt completion services, communicating availability of the call attempt completion services to the caller before the manual termination may not be possible.

There is a need for communicating availability of call attempt completion services before and after manual termination of the call attempt by the caller.

Hence, there is an unmet need for completing a call attempt made by a first party on a first network to a second party on a second network by providing a messaging service, where availability of the messaging service for sending a message to the second party is communicated to the first party before or after manual termination of the call attempt by the first party.

SUMMARY OF THE INVENTION

This summary is provided to introduce a selection of concepts in a simplified form that are further described in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.

The method and system disclosed herein addresses the need for completing a call attempt made by a first party on a first network to a second party on a second network by providing a messaging service, where availability of messaging service for sending a message to the second party is communicated to the first party before or after manual termination of the call attempt. The second network may be the same as the first network, or one of any other networks excluding the first network. The first network detects termination of the call attempt made by the first party on the first network to contact the second party on the second network. The call attempt may, for example, be terminated due to occurrence of a busy signal, an out of coverage signal, an unreachable signal, congestion of one or more of the first network and the second network, an unanswered signal from the second party, or manual call termination by the first party.

The first network communicates availability of a messaging service to the first party on detection of termination of the call attempt. The messaging service may, for example, be a short messaging service (SMS), a voice SMS service, a multimedia messaging service, and a multimodal messaging service. The first network may communicate the availability of the messaging service to the first party via, for example, a voice call, an SMS message, or an alert based on unstructured supplementary service data. The first network may communicate the availability of the messaging service to the first party prior to manual call termination by the first party or after the manual call termination by the first party. The first network may communicate the availability of the messaging service to the first party after manual call termination by the first party via a voice call. The first party is not billed for the communication of the availability of the messaging service.

Acceptance and declination of the messaging service by the first party may, for example, be detected by an explicit dual tone multi frequency input, an implicit predefined timeout, or a subscription of the first party to the messaging service. On acceptance of the messaging service by the first party, the first party creates a message to be delivered to the second party on the second network. Creating the message by the first party may, for example, comprise recording one or more of a text SMS message, a voice SMS message, a multimedia messaging service message, and a multimodal message on a communication device of the first party.

The first network delivers the created message to the second party on the second network. The text SMS message, the voice SMS message, the multimedia service message, and the multimodal message are delivered to the second party in a text short messaging service message format, a voice SMS message format, a multimedia messaging service message format, and a multimodal message format respectively. The first party is billed for the delivery of the created message. On declination of the messaging service by the first party, the first network sends a missed call notification to the second party. The first network may send a missed call notification to the second party on declination of the messaging service by the first party.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 illustrates a method of completing a call attempt made by a first party 201 on a first network 203 to a second party 205 on a second network 204. The first party 201, the first network 203, the second party 205, and the second network 204 are illustrated in FIG. 2. The second network 204 may be the first network 203, or one of multiple networks excluding the first network 203. The call may be initiated on a wireless telephony network or a wired telephony network. The first network 203 detects 101 termination of the call attempt. The call attempt may, for example, be terminated due to occurrence of a busy signal, an out of coverage signal, an unreachable signal, congestion of one or more of the first network 203 and the second network 204, an unanswered signal from the second party 205, and manual call termination by the first party 201.

On detection of the termination of the call attempt, the first network 203 communicates 102 availability of a messaging service to the first party 201. The messaging service may, for example, be a short messaging service (SMS), a voice SMS service, a multimedia messaging service, and a multimodal messaging service. As used herein, the term "multimodal messaging" refers to a mode of communication that seamlessly combines graphics, text, and audio output with speech, text, and touch input to provide an enhanced user interface.

The multimodal messaging service combines voice data and other modalities, for example, image, video, etc. with a text SMS message. The multimodal messaging service enables use of multiple modalities of communication based on requirements of the first party 201 and the usage environment. As used herein, modalities refer to any human mode of interaction on the input side of an application, for example, the first party's 201 voice, any visual mode, or combination of voice and any visual mode, etc., that allows the first party 201 to speak, hear, type, touch or see in that application, and one or more human interaction modes on the output side of the application such as the second party's 205 ability to hear, visually see, or simultaneously hear and visually see the output. Multimodal interactions thereby extend web or other application user interface to allow multiple modes of interaction, offering the first party 201, for example, the choice of using their voice, or an input device such as a key pad, keyboard, mouse or stylus. For output, the second party 205 will, for example, be able to listen to spoken prompts and audio, to view information on graphical displays, and to simultaneously listen to and view an output.

Multimodal messaging enables users to send and receive voice messages associated directly with text SMS messages. To send a multimodal message, the first party 201 composes a message to be sent using SMS technology using a text input device, for example, a keypad of a mobile phone. The composed text message is associated and combined with a voice message recorded by the first party 201. The combined message is sent to the second party 205 via a multimodal messaging platform. The multimodal messaging platform synchronizes and processes input voice and text information and transfers the synchronized and processed information to a mobile phone of the second party 205. The multimodal platform enables wireless carriers and service providers to offer applications with integrated voice and visual interfaces.

The second party 205 may then read the received text message and retrieve the associated voice message via a link provided in the received text message or in a separate text message by the multimodal platform. A speech recognition engine may be used for control of the playback and recording of voice messages as well as control of other messaging functions. Multimodal messaging may be implemented using wireless telephone devices capable of sending and receiving SMS text messages and may also be extended to different device types and network technologies.

The first network 203 may communicate the availability of the messaging service to the first party 201 by, for example, a voice call, an SMS message, or an alert based on unstructured supplementary service data (USSD). The first network 203 may communicate the availability of the messaging service to the first party 201 prior to manual call termination by the first party 201 or after the manual call termination by the first party 201. For example, if the first party 201 attempts to call the second party 205 and encounters a busy signal, the availability of the messaging service may be communicated to the first party 201 before the first party 201 manually terminates the call by pressing an "END" key on the first party's 201 communication device 202. However, if the first party 201 manually terminates the call by pressing the "END" key before the communication of the availability of the messaging service, the first network 203 may communicate the availability of the messaging service after the manual call termination by placing a voice call to the first party 201. The first party 201 is not billed for the communication of the availability of the messaging service.

The first party 201 accepts 103 the messaging service. The first network 203 detects the acceptance or declination of the messaging service by the first party 201 by an explicit dual tone multi frequency (DTMF) input, for example, by the first party 201 pressing a "#" key on the communication device 202, an implicit predefined timeout, for example, by the first party 201 waiting on the line for a predefined period of time, or a subscription of the first party 201 to the messaging service. If the first party 201 declines the messaging service, the first network 203 sends a missed call notification to the second party 205. When the first party 201 accepts the messaging service, the first party 201 creates 104 a message to be sent to the second party 205 on the second network 204. The first party 201 may create the message, for example, by typing a text SMS message, recording a voice SMS message, and by composing an MMS message or a multimodal message on the first party's 201 communication device 202. The first network 203 then delivers 105 the created message to the second party 205 on the second network 204. The call attempt made by the first party 201 on the first network 203 to the second party 205 on the second network 204 is thereby completed.

The first network 203 delivers the created message by transmitting the created message to the second party 205 in a suitable format. The created text SMS message is delivered in a text SMS format. The recorded voice SMS message is delivered in a voice SMS message format. The recorded MMS message is delivered in an MMS message format. The recorded multimodal message is delivered in a multimodal message format. The first network 203 may bill the first party 201 for the delivery of the created message. FIG. 2 illustrates a system for completing a call attempt made by a first party 201 on a first network 203 to a second party 205 on a second network 204. The second network 204 may be the first network 203, or one of multiple networks excluding the first network 203. A system for completing a call attempt made by the first party 201 to the second party 205 within the first network 203 is exemplarily illustrated in FIG. 3. The system disclosed herein comprises a call termination detection module 203a, a service communication module 203b, an acceptance and declination detection module 203c, a delivery engine 203d, a billing engine 203e, a message database 203f, and a message creation module 202a. The call termination detection module 203a, the service communication module 203b, the acceptance and declination detection module 203c, the delivery engine 203d, the billing engine 203e, and the message database 203f may be part of the first network 203. The message creation module 202a may be provided on a communication device 202 of the first party 201.

The call termination detection module 203a detects termination of a call attempt made by the first party 201 to contact the second party 205. The call termination detection module 203a may, for example, detect the termination of the call attempt due to occurrence of a busy signal, an out of coverage signal, an unreachable signal, congestion of one or more of the first network 203 and the second network 204, an unanswered signal from the second party 205, and a manual call termination by the first party 201. On detection of the termination of the call attempt, the service communication module 203b communicates availability of a messaging service to the first party 201. The service communication module 203b may, for example, communicate availability of the messaging service by a voice call, a short message service message, or an alert based on unstructured supplementary service data. The messaging service may, for example, be one or more of a short messaging service (SMS), a voice short messaging service, a multimedia messaging service (MMS), and a multimodal messaging service. The service communication module 203b may communicate the availability of the messaging service prior to manual call termination by the first party 201 or after the manual call termination by the first party 201. The first party 201 may accept or decline use of the messaging service. The acceptance and declination detection module 203c may, for example, detect the acceptance or the declination of the messaging service by the first party 201 by an explicit dual tone multi frequency (DTMF) input, an implicit predefined timeout, or a subscription of the first party 201 to the messaging service. On acceptance of the messaging service, the first party 201 may create a message to be sent to the second party 205 on the second network 204 using the message creation module 202a. The message creation module 202a may, for example, enable the first party 201 to create a text SMS message, and record a voice SMS message, an MMS message, or a multimodal message on the communication device 202.

The message database 203f may store the created message. The delivery engine 203d then delivers the created message to the second party 205 on the second network 204. The delivery engine 203d delivers the created message by transmitting the created message to the second party 205 in a suitable format. The delivery engine 203d delivers the text SMS message in a text SMS format, the recorded voice SMS message in a voice SMS message format, the composed MMS message in an MMS message format, and the composed multimodal message in a multimodal message format. The delivery engine 203d may also deliver a missed call notification to the second party 205 if the first party 201 declines use of the messaging service.

The billing engine 203e bills the first party 201 for the delivery of the created message. The billing engine 203e determines the bill amount to be paid by the first party 201 for the delivery of the created message. The billing engine 203e does not bill the first party 201 for the communication of the availability of the messaging service. The message database 203f stores communication information of the messaging service, missed call notifications sent to the second party 205, and billing information of the first party 201.

FIG. 4 exemplarily illustrates a flowchart of the steps for completing a call attempt made by a first party 201 to a second party 205 within a first network 203. Consider party "A" who attempts 401 to call party "B". Due to conditions such as occurrence of a busy signal, an out of coverage signal, an unreachable signal, congestion of the first network 203, an unanswered signal from the party "B", or manual termination by the party "A", the call attempt may be terminated. The first network 203 detects the termination 402 of the call attempt. The first network 203 then queries 403 party "A" to use the messaging service. If party "A" declines the use of the messaging service, the first network 203 terminates 404 the call. If party "A" accepts the messaging service, party "A" provides 405 message content by typing a text SMS message, recording a voice SMS message, an MMS message, or a multimodal message on party "A'"s communication device 202. The first network 203 then delivers 406 the message content created by party "A" to party "B". Party "B" then retrieves 407 the message content from the first network 203. Party "B" may, for example, read the SMS, listen to the voice SMS, view the MMS, or view and listen to the multimodal message. On retrieval of the created message, party "A" may be notified of the receipt 408 by the party "B".

Consider an example of a first party 201 John attempting to call a second party 205 Jane using a mobile phone as a communication device 202. John is a subscriber of a first network 203 Networkl and Jane is a subscriber of a second network 204 Network2. Alternatively, both John and Jane may be subscribers of Networkl. When John attempts to call Jane, Jane may be out of reach of Network2 and the call may be terminated.

Networkl detects the termination of the call attempt by John and informs John about the availability of the messaging service. Networkl may inform John about the availability of the messaging service before he manually terminates the call by pressing the "END" key on his mobile phone. If John manually terminates the call before Networkl informs him about the availability of the messaging service, Networkl may send John an SMS message or may contact John via a voice call to inform him about the availability of the messaging service. John is not billed for the information about the availability of the messaging service.

Networkl may provide John the option to send a message to Jane by pressing the

"#" key on his mobile phone. If John does not want to send a message to Jane, Networkl will send a missed call notification to Jane. Jane receives the missed call notification when she comes back into the reach of Network2. If John decides to send a message to Jane, he creates the message on his mobile phone. Networkl delivers the created message to Jane and bills John for the delivery of the message.
