## Background
RELATED APPLICATION
This application claims priority to U.S. Provisional Patent Application No. 60/969,419, filed Aug. 31, 2007, the entirety of which is hereby incorporated by reference.


TECHNICAL FIELD
The present disclosure relates generally to voicemail and, more particularly, to providing a toggle feature for toggling voicemail class of service (CoS) between plain old voicemail (POVM) and visual voicemail (VVM).
BACKGROUND
Voicemail systems allow a caller to leave a voice message if the desired recipient is unavailable. Traditional voicemail systems (referred to herein as plain old voicemail or POVM) allow a subscriber to place a call to a voicemail system to access messages stored in his or her voicemail box. This is done through a telephone user interface (TUI) that facilitates interaction between the subscriber and the voicemail system. The TUI provides functions for the subscriber to listen to messages, skip messages, delete messages, and save messages. The TUI also provides functions for the subscriber to set a voicemail greeting, record a voicemail greeting, record a name, and set/change a password.
A subscriber with multiple voicemail messages is required to listen to, skip, delete, or save each message while reviewing the voicemail box. This is time consuming and can be frustrating for the subscriber in situations where an important message has been deposited, requiring the subscriber to listen to, skip, delete or save each message in search of the important message.
To help reduce the need to search through multiple messages, various improved voicemail systems have been developed that allow messages to be stored based on a priority scheme to increase the efficiency of listening to voicemail messages. Often, these systems use a telephone number of the caller to identify a priority for a message and position the voicemail messages in order based on the assigned priorities. When the recipient accesses the voicemail system to acquire voicemail messages, the recipient is presented with each voicemail message in order of the priority or importance to the recipient. This reduces unwanted listening or skipping through multiple voicemail messages to find an important message. However, an important message can easily be relegated to a position of low importance if the subscriber has not previously set the priority for the caller. In this system, the priority for an incoming voicemail message is determined directly by the telephone number associated with the caller.
The aforementioned systems fail to allow a subscriber to select the exact voicemail message the subscriber would like to hear. Further, the aforementioned systems require the use of a TUI to access the voicemail system. Still further, these systems merely notify a subscriber of a pending voicemail message with a message waiting indicator (MWI) and require that the subscriber access the voicemail system to retrieve the pending message(s).
Thus, it is desirable to create new enhanced voicemail systems and novel methods for providing visual voicemail (VVM) services. Moreover, there is a need to toggle between VVM service and POVM service from a subscriber's mobile device.
SUMMARY
A method for toggling voicemail class of service (CoS) can include receiving a subscriber-initiated CoS change request at a billing system, wherein the CoS change request includes a request to change from a first CoS associated with a first voicemail system (VMS) to a second CoS associated with a second VMS. The subscriber-initiated CoS change request can be received from a mobile device. The method can further include validating the CoS change request at the billing system, sending a CoS delete request to the first VMS to at least temporarily disable a first voicemail account, and sending a provisioning request to the second VMS to provision a second voicemail account. The validating step can include determining if a subscriber associated with the first voicemail account is authenticated for the voicemail service provided by the second VMS.
The aforementioned method can further include sending a first boot message to the mobile device if the second VMS is a visual voicemail system (VVMS) and the second voicemail account is a VVM account.
In one embodiment, the first VMS is a plain old voicemail system (POVMS) and the second VMS is a VVMS. In another embodiment, the first VMS is a VVMS and the second VMS is a POVMS.
A computer-readable medium on a mobile device includes computer-executable instructions that, when executed, perform the steps of receiving an input to toggle between a first voicemail service and a second voicemail service, generating and sending a voicemail CoS change request message based upon the input, and receiving a notification that a voicemail account is provisioned on the second VMS. The CoS change request can include a request to change from a first CoS associated with a first VMS to a second CoS associated with a second VMS.
The aforementioned computer-readable medium can further include instructions that, when executed, perform the step of receiving a first boot message if the second VMS is a VVMS and the second voicemail account is a VVM account.
In one embodiment, the first voicemail service is a POVM service and the first VMS is a POVMS, and the second voicemail service is a VVM service and the second VMS is a VVMS. In another embodiment, the first voicemail service is a VVM service and the first VMS is a VVMS, and the second voicemail service is a POVM service and the second VMS is a POVMS.
A system for providing a voicemail CoS toggle feature includes a mobile device configured to generate and send a subscriber-initiated CoS change request to a billing system, wherein the CoS change request includes a request to change from a first CoS associated with a first VMS to a second CoS associated with a second VMS. The billing system can be configured to receive the subscriber-initiated CoS change request, validate the CoS change request, generate and send a CoS delete request to the first VMS to at least temporarily disable a first voicemail account, and generate and send a provisioning request to the second VMS to provision a second voicemail account.
The aforementioned billing system can be further configured to generate and send a first boot message if the second VMS is a VVMS and the second voicemail account is a VVM account.
In one embodiment, the first VMS is a POVMS and the second VMS is a VVMS. In another embodiment, the first VMS is a VVMS and the second VMS is a POVMS.

DETAILED DESCRIPTION
As required, detailed embodiments of the present disclosure are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary examples of the disclosure that may be embodied in various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as an illustration, specimen, model or pattern. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials or methods have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.
Referring now to the drawings wherein like numerals represent like elements throughout the several views, FIG. 1 schematically illustrates a wireless communications network 100 in which the various embodiments of the present disclosure can be implemented. By way of example, the wireless communications network 100 can be configured as a 2G GSM (Global System for Mobile communications) network and provide data communications via GPRS (General Packet Radio Service), and EDGE (Enhanced Data rates for GSM Evolution). By way of further example, the wireless communications network 100 can be configured as a 3G UMTS (Universal Mobile Telecommunications System) network and provide data communications via the HSPA (High-Speed Packet Access) protocol family, such as, HSDPA (High-Speed Downlink Packet Access), EUL (Enhanced Uplink) or otherwise termed HSUPA (High-Speed Uplink Packet Access), and HSPA+ (Evolved HSPA). The wireless communications network 100 is also compatible with future mobile communications standards including, but not limited to, pre-4G and 4G, for example. The wireless communications network 100 can be configured to provide messaging services via Short Message Service (SMS), Multimedia Message Service (MMS), and instant messaging, for example. The wireless communications network 100 can also be configured to provide advanced voicemail messaging features, such as visual voicemail.
The illustrated communications network 100 includes a plain old voicemail system (POVMS) 102 and a visual voicemail system (VVMS) 104. The POVMS 102 and VVMS 104 are illustrated as separate systems for clarity, but can be a single system with capabilities to handle both POVM and VVM services. Accordingly, at times, the POVMS 102 and VVMS 104 are collectively referred to as the voicemail system (VMS) 102, 104. It is contemplated that a subscriber can have at least one voicemail account in one or both of the POVMS 102 and the VVMS 104. It is further contemplated that the POVMS 102 and the VVMS 104 can be synchronized automatically at any time or manually based upon a request from the either or both of the subscriber and the service provider that operates the VMS 102, 104.
The VVMS 104 is illustrated as being in communication with a content delivery server (CDS) 106, an unstructured supplementary service data (USSD) server 108, and a billing system 109. The POVMS 102 is also illustrated as being in communication with the USSD server 108 and the billing system 109.
The POVMS 102 and the VVMS 104 can each include a telephony server (TS) 107, 110 for handling incoming voicemail inquiries via a telephone user interface (TUI) 112 and a storage server (SS) 114, 116 for storing and managing voicemail messages for a plurality of voicemail accounts, respectively.
The USSD server 108 can be configured to: receive, decode, and process new USSD messages; perform database queries to retrieve the VMS hostname serving a subscriber; perform database queries to resolve the VMS hostname to the corresponding IP address; obtain the subscriber's voicemail CoS; and send the subscriber's voicemail CoS to a VVM enabled device 118 (also referred to herein as the subscriber's mobile device (MD) 118). Accordingly, the USSD server 108 is in communication with a home location register (HLR) 120, a subscriber database 122, and a domain name server (DNS) 124 to facilitate these functions. The MD 118 can be, but is not limited to, a user equipment, a mobile terminal, a cellular telephone, a personal digital assistant (PDA), a handheld computer, or combinations thereof, and the like.
The billing system 109 can be configured to delete a first CoS on a first voicemail system and provision a second CoS on a second voicemail system. In one embodiment, the billing system 109 can be configured to delete a POVM CoS and provision a VVM CoS on the respective systems. This embodiment is described in detail below with reference to FIG. 2. In another embodiment, the billing system 109 can be configured to delete a VVM CoS and provision a POVM CoS on the respective systems. This embodiment is described in detail below with reference to FIG. 4.
The subscriber database 122 can be configured to store and manage subscriber data, such as, but not limited to, account information, services information, and equipment information for a plurality of subscribers. The subscriber database 122 can be in communication with the billing system 109 for retrieving billing information for a subscriber. It is contemplated that the subscriber database 122 and billing system 109 can be combined.
The DNS server 124 can be configured to maintain a database for resolving host names and IP addresses for various network nodes, such as the POVMS 102 and VVMS 104, for example. The USSD server 108 can retrieve a VMS hostname serving a subscriber from the subscriber database 122 and query the DNS 124 by specifying the VMS hostname to resolve the corresponding IP address.
The HLR 120 can be configured to provide routing information for mobile-terminated calls and short message service (SMS) messages. The HLR 120 is in communication with a mobile switching center (MSC) and visiting location register (VLR) 126. The MSC/VLR 126 is in communication with the MD 118 and a short message service center (SMSC) 128. The SMSC 128 can be configured to deliver SMS messages and message waiting indicator (MWI) messages.
The POVMS 102 and VVMS 104 can be configured to store a plurality of voicemail accounts. Each voicemail account can include a voicemail box in which voicemail messages can be deposited for a subscriber. The number of voicemail messages capable of being stored per account can be determined by the voicemail service provider or a third party, such as the system manufacturer, for example. The maximum voicemail message length can also be set. The number of voicemail messages and the maximum voicemail message length can be configurable on the POVM 102 and VVMS 104.
Prior to a subscriber being provisioned for visual voicemail service on the VVMS 104, the subscriber's voicemail box is in a not provisioned state. After being provisioned for visual voicemail service, the subscriber's voicemail box state is changed to provisioned—not initialized state to reflect that the subscriber is provisioned for service, but has not yet initialized service via a first boot access process described later with reference to FIG. 3. Upon completion of the first boot access process, the VVMS 104 state can be changed to provisioned—initialized to reflect that the subscriber is provisioned for voicemail service and has completed the first boot access process. It is contemplated that in certain embodiments a subscriber's VVM account remains active, but temporarily disabled or temporarily decommissioned.
State changes to voicemail messages, whether requested through TUI via POVM methods or directly on the MD 118 via VVM methods, are automatically updated in both the voicemail box and on the subscriber's MD 118. This ensures automatic and full synchronization between the subscriber's MD 118 and the VVMS 104 so that the latest voicemail information is stored on the subscriber's MD 118. The subscriber's VMS-hosted voicemail box can recognize and maintain message states for each message such as, but not limited to, an unheard—new state, a skipped state, and a saved—read state. Deleted messages can be deleted from the VVMS 104, via the TUI or directly on the MD 118. The message is deleted on both the VVMS 104 and the MD 118. However, in an alternative embodiment, deleted messages remain accessible on the MD 118 and/or on the VVMS 104 for a specified period of time to allow the message to be recovered in the case of accidental or premature deletion. In other embodiments, the VVMS 104 discards all messages after the MD 118 has successfully received and stored the available message content.
The MD 118 voicemail box also recognizes and maintains message states. The MD 118 voicemail box can have message states for each message including, but not limited to, an unheard—new state, a saved—read state, and a deleted state. The MD 118 does not require a skipped state because VVM provides an interface that allows a subscriber to access any message regardless of the order in which the message was received and is not subject to restraint of a priority scheme. As mentioned above, the MD 118 voicemail box deleted state can be configured such that the message is available for recovery or merely as an indication that the message has been deleted. Either of these options can be set to be available for a time specified by either the subscriber via a device input or by the voicemail service provider.
Referring now to FIG. 2, an exemplary message flow diagram of a process 200 for toggling voicemail CoS is illustrated, according to one embodiment of the present disclosure. In the illustrated embodiment, a subscriber desires to change their voicemail CoS from a POVM service to a VVM service. The subscriber may have been previously provisioned for VVM service or may be accessing the VVM service for the first time. The general assumption with regard to this embodiment is that the MD 118 is a VVM enabled device. That is, the MD 118 includes VVM application specific software.
The process 200 begins at the MD 118 whereby a user can select an option to enable VVM. In step 202, after enabling the VVM option, the MD 118 can generate CoS change request and send the request to the billing system 109 for authentication. The request can be a lightweight directory access protocol (LDAP) request sent via an access point name, such as a Wireless Application Protocol (WAP) APN or WEB APN, for example. Alternatively, it is contemplated that the request can be delivered via an SMS message, a USSD message, or any other message type. It should be understood that all messages sent to and from the various nodes in the process 200 can be performed using LDAP, SMPP, USSD and like protocols.
After receipt of the CoS change request, the billing system 109 can determine if the subscriber is authenticated to use VVM. In step 204, the billing system 109 can generate an appropriate positive or negative acknowledgement response message (POSACK or NACK) based upon the authentication status. The billing system 109 can then send the response message to the MD 118. If the subscriber is authenticated for VVM service, the billing system 109 can generate a POVM CoS delete message and send the delete message to the POVMS 102 in step 206. The POVMS 102 can be identified by a voicemail system identification (VMS_ID). The POVMS 102 can receive the delete message and delete the subscriber's voicemail box or temporarily disable the voicemail box until a later request is received to reinstate the voicemail box. If the subscriber is not authenticated for VVM service, the billing system 109 can generate a NACK response message and send the NACK response message to the MD 118. The MD 118 can receive the NACK response message and can prompt the subscriber to call customer service.
In step 208, the billing system 109 can assign a VVMS 104 to the subscriber. The billing system 109 can use load balancing, for example, to determine in which VVMS the subscriber's voicemail box should be created. Alternatively, the billing system 109 can select the VVMS 104 in which the subscriber had a previous voicemail box, for example, a previously disabled voicemail box. The VVMS 104 can create a voicemail box for the subscriber or can enable a previously disabled voicemail box. In step 210, the conditional call forwarding (CCF) feature on the subscriber's account can be reset for the new VVMS 104 and a first boot message can be sent to the MD 118. An exemplary first boot message is described below with reference to FIG. 3.
Referring now to FIG. 3, a message flow diagram of an exemplary process 300 for first boot access of a subscriber's MD 118 to a VVMS 104 is illustrated, according to the present disclosure. The first boot access process 300 assumes that, the subscriber has been provisioned for VVM service and has the proper voicemail CoS as provided in the process 200 described above in FIG. 2. When the subscriber is initially provisioned to the VVMS 104 with a VVM CoS, the subscriber's account can be enabled for voicemail notification via the CDS 106. The VVMS 104 can initiate a notification message to the CDS 106 that is intended for delivery to the subscriber's MD 118 via a short message peer-to-peer (SMPP) message. This enables the subscriber to have confirmation that the VVM service is enabled and to immediately access the service via a VVM application. A visual prompt can be presented to the subscriber as a cue or reminder to setup a voicemail box prior to receipt of incoming voice messages. Conventional voicemail, in contrast, blocks receipt of new messages until the mailbox is set up, or notifies the subscriber of the first new voice messages thereby prompting the subscriber to place a call to retrieve them, but bars access to those messages until the subscriber sets up the mailbox. The visual prompt of the present disclosure advantageously eliminates the annoyance and need to access the voicemail system via the TUI 112 to setup the voicemail box and ensures the subscriber sets up a voicemail box.
The VVM service uses several parameters to enable automatic synchronization between the MD 118 and the VVMS 104. For example, prior to first boot, the MD 118 does not have this information. Accordingly, the first boot process 300 described below provides an initial SMPP message including a basic set of parameters for future synchronization sessions.
The process 300 begins when the VVMS 104 generates an SMPP notification message (notification_SM) in step 302. For example, a notification_SM message can include, but is not limited to, the hostname and port number for the subscriber's CDS 106, a token identifying the subscriber's VVMS 104, the subscriber's voicemail box ID (mailbox_ID) embedded with the token to uniquely identify the subscriber for the VVMS 104, and the current VVMS password (if the password has not already been set). In an alternative embodiment, the notification_SM can include the IP address and port number for the subscriber's CDS 106 and the mailbox_ID. The password and token can be added to increase security and preserve data integrity. If a password is used, the password may be unencrypted and instead the password can be obscured to hide the actual default password digits.
After the notification_SM message is generated, the VVMS 104 can send the message to the CDS 106 in step 304. In step 306, the CDS 106 can receive the notification_SM message and generate a VVM application directed notification_SM message and send the message to the SMSC 128. The SMSC 128 can receive the message and forward the message to the MD 118, in step 308. The application directed short message can be received by the MD 118 and sent directly to the VVM application. Typically, the user will not be notified of the incoming short message. The VVM application can generate any prompts necessary to guide the user through setup and other processes identified in the application directed short message upon receipt of the short message or at a time thereafter.
For situations in which VVM is temporarily unavailable for network maintenance, device maintenance, or other unforeseen circumstances, the VVM subscriber can access voicemail via the TUI 112 as a default access method.
Referring now to FIG. 4, a message flow diagram of an exemplary process 400 for toggling voicemail CoS is illustrated, according to another embodiment of the present disclosure. In the illustrated embodiment, a subscriber desires to change their voicemail CoS from a VVM service to a POVM service. The subscriber may have been previously provisioned for POVM service or may be accessing the POVM service for the first time. It should be understood that a subscriber that is provisioned for VVM service can also by default be provisioned for VVM service. That is, a VVM subscriber can use the TUI 112 to access voicemail messages stored at VMS 102, 104.
The process 400 begins at the MD 118 whereby a user can select an option to disable VVM. In step 402, after disabling the VVM option, the MD 118 can generate CoS change request and send the request to the billing system 109 for authentication. The request can be a LDAP request sent via an access point name, such as a WAP APN or WEB APN, for example. Alternatively, it is contemplated that the request can be delivered via an SMS message, a USSD message, or any other message type. It should be understood that all messages sent to and from the various nodes in the process 400 can be performed using LDAP, SMPP, USSD and like protocols.
After receipt of the CoS change request, the billing system 109 can determine if the subscriber is authenticated to change VM CoS. In step 404, the billing system 109 can generate an appropriate positive or negative acknowledgement response message (POSACK or NACK) based upon the authentication status. The billing system 109 then sends the response message to the MD 118.
In step 406, the billing system 109 can generate a VVM CoS delete message and send the delete message to the VVMS 104. The VVMS 104 can be identified by a voicemail system identifier (VMSID). The VVMS 104 can receive the delete message and delete the subscriber's voicemail box or temporarily disable the voicemail box until a later request is received to reinstate the voicemail box. If the subscriber is not authenticated to change voicemail CoS, the billing system 109 can generate a NACK response message and send the NACK response message to the MD 118. The MD 118 can receive the NACK response message and can prompt the subscriber to call customer service.
In step 408, the billing system 109 can assign a POVMS 102 to the subscriber. The billing system 109 can use load balancing, for example, to determine in which POVMS the subscriber's voicemail box should be created. Alternatively, the billing system 109 can select the POVMS in which the subscriber had a previous voicemail box, for example, a previously disabled voicemail box. The POVMS 102 can create a voicemail box for the subscriber or can enable a previously disabled voicemail box. In step 410, the CCF feature on the subscriber's account can be reset for the new POVMS.
FIG. 5 is a schematic block diagram illustrating an exemplary mobile device 118 for use in accordance with an exemplary embodiment of the present disclosure.

Referring also now to FIG. 6, an exemplary graphical user interface (GUI) screen 600 for accessing phone functions including toggling visual voicemail service is illustrated, according to the present disclosure. The illustrated GUI screen 600 includes a visual voicemail toggle option 602, a call TUI option 604, and a change voicemail password option 606. The visual voicemail toggle option 602 allows a user to turn VVM on and off. For example, a user may desire to turn VVM off when roaming internationally due to the high costs associated with international data roaming. Enabling the voicemail toggle option 602 can trigger the MD 118 to generate and send a CoS change request message 202, 402 to the billing system 109. The call TUI option 604 is a short cut way a user can call the TUI 112 to listen to voicemail messages or change voicemail settings of the POVM 102 or VVMS 104 via the TUI 112. The change voicemail password option 606 can allow the user to change the voicemail password associated with their VVM service on the MD 118.
The illustrated GUI screen 600 also includes a sort order option 608 whereby the user can select the order by which contacts are sorted, and a display order option 610 whereby the user can select the order by which contacts are displayed. The illustrated GUI screen 600 can further include a call forwarding option 612 whereby the user can select a call forwarding number or numbers, a call waiting option 614 whereby the user can enable/disable a call waiting feature, a “show my caller ID” option 616 whereby the user can enable/disable a caller ID feature, and a TTY option 618 whereby the user can enable/disable a TTY feature.
The law does not require and it is economically prohibitive to illustrate and teach every possible embodiment of the present claims. Hence, the above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the disclosure. Variations, modifications, and combinations may be made to the above-described embodiments without departing from the scope of the claims. All such variations, modifications, and combinations are included herein by the scope of this disclosure and the following claims.
