Widespread use of wireless phones has made them an indispensable tool to businesses and individuals alike. Many individuals carry their wireless phone almost everywhere they go just in case they need to make a call. As a result, friends and colleagues have come to reasonably expect they can get a hold of each other almost immediately with a single phone call.
While talking on a wireless phone is generally preferred, it is sometimes not possible as one party may be busy or in a meeting. Instead of a voice conversation, people may instead use their wireless phone to type a short text message and send it to another user. The short text message is sent over a specially provisioned data channel within the voice network called Short Messaging Service (SMS). SMS addresses messages using the same phone number provisioned to the wireless phone for voice communication but sends them over the data channel on the voice network. This data channel for SMS is generally limited to 140 text characters since it relies upon unused bandwidth made available when a control channel within the voice network is idle and not occupied setting up or managing voice calls.
Operators of the voice networks discovered they could charge users an additional fee for using SMS even though it cost very little for them to implement. The voice networks effectively charge for each message sent thus making the SMS communication a source of revenue. Even higher fees apply to users who send international messages to people outside their country.
Unfortunately, SMS communication remains a relatively closed and proprietary system as it is controlled by the operators of the voice network. Little has been done to increase the features associated with SMS messaging or decrease the costs as there are no competing systems. People sending text messages generally accept the 140 character limitation for sending each transmission and the relatively costly fee structure. Despite these limitations, the popularity of SMS communication on wireless devices continues to attract new users and grow in popularity. There is a need to develop an easy to use messaging system with lower costs and more features.
Aspects of the present invention provide a method and system of verifying the association between a phone number and a phone device. One aspect of the present invention independently verifies that a phone number has been provisioned on a voice network to a phone device and then uses the phone number on a new synthetic communication network for transmitting data. Aspects of the present invention initially receive a request to add a phone device previously registered with a voice network to the synthetic communication network for data. The phone number initially provided with the phone device on the voice network is classified as an unconfirmed phone number. For example, the unconfirmed phone number may not yet be associated with any phone device and therefore cannot be used on the synthetic communication network. The unconfirmed phone number may also be used as a ploy for diverting messages from an intended recipient to an unintended recipient. To confirm the phone number, one aspect of the present invention attempts transmission of a verification message from the phone device through a data channel on the voice network and back to the phone device. It is presumed that the phone device has access to the data channel on the voice network. Aspects of the present invention determine whether the verification message was received by the phone device over the data channel of the voice network. If the verification message was received then aspects of the present invention indicate that the unconfirmed phone number should be identified as a confirmed phone number associated with the phone device. Once confirmed, the method and system authorizes data communication using the phone devices on the synthesized communication network with the confirmed phone number.
Yet another aspect of the present invention concerns a subsequent verification of the association between a phone number and the phone device. This can be useful for continued use of a phone number and phone device on the synthesized network in accordance with aspects of the present invention. From time to time, the phone number of a phone device may need to be reconfirmed in a case the phone number has been abandoned and reassigned to a different phone device. In this implementation, the method and system receives an unconfirmed phone number asserted to be associated with a particular phone device. To confirm the phone number, aspects of the present invention generate a verification message on the phone device to verify the unconfirmed phone number. This verification message is transmitted from the from the phone device through the data channel on the voice network using the unconfirmed phone number. If the unconfirmed phone number returns back to the phone device then the previously unconfirmed phone number may become confirmed. Accordingly, aspects of the present invention determine whether the verification message received by the phone device over the data channel of the voice network was in fact the verification message for the unconfirmed phone number. If the verification message was received then the method confirms the verification message and indicates the unconfirmed phone number should be identified as a confirmed phone number. If the verification is not received then aspects of the present invention may indeed not confirm the phone number association with the phone device. Aspects of the present invention may further remove or disallow the phone number and phone device from further communications on the synthetic communication network.
Like reference numbers and designations in the various drawings indicate like elements.
Aspects of the present invention provide one or more of the following advantages. Users can registered their phone devices and join a synthetic communication network using a phone number previously only available for use on a voice network. The same phone number provisioned by a phone company or wireless phone provider can be reused on the synthetic communication network and take advantage of new data communication services. Some of the data communication services made available through the synthetic communication network includes features not available on the conventional voice network. For example, users of the synthetic communication network may use their phone number to enjoy a feature-rich form of text messaging on their phone devices not available on the voice network.
The synthetic communication network also offers more competitive pricing on data communication services than a voice network. Aspects of the present invention combine the convenience of using a phone number with a development platform for use with the Internet and other data networks. By opening the development platform to data networks, users are not limited to pricing schemes dictated by a phone company or wireless phone provider managing the voice network. Instead, the users may use their phone number and directly subscribe to new data communication services through the Internet. While the phone company or wireless provider may control the initial provisioning of a phone number, aspects of the present invention allows the phone number to access a wider range of data communication services with competitive pricing and feature richness.
Phone number verification implemented in accordance with aspects of the present invention enables phone numbers provisioned from the voice network to be reused on a data network. The synthetic communication client works with the synthetic communication server to make sure the phone number is associated with the particular phone device. Aspects of the present invention may re-verify the association between the phone number and the phone device just in case the phone number has been abandoned and reassigned by the voice network to a different phone device. Once a phone number is verified, the phone device may register and begin using their phone device on the synthesized communication network without requesting additional services from their wireless phone carrier.
The synthetic communication network of the present invention further allows the use of phone numbers provisioned from voice networks around the world. A normalization process performed on the phone numbers in accordance with the present invention prevents conflicts from occurring between two different phone numbers. Even if phone numbers from two different countries initially appear the same, normalization ensures that phone numbers can be distinguished. Normalization performed in accordance with aspects of the present invention allows phone numbers provisioned from around the world to be used on the synthetic communication network.
Aspects of the present invention can also keep status on phone devices even though they might be members of different voice networks. The normalized phone number for each phone device is used to identify and track the status of each phone device. If a user changes the status on a phone device then all other phone devices on the synthetic communication network may potentially receive the status update.
A wireless phone provider may provide voice network 112 and communication bridge 110 in order to connect phone devices on voice network 112 to data network 104 and the Internet or an Intranet. Alternately, voice network 112 may be provided by a hybrid phone provider offering both wired and wireless devices that also have access to the Internet or an intranet over communication bridge 110 and data network 104. In general, voice network 112 provides voice communication between phone devices registered on the voice network 112 and data services like SMS text messaging through data channel 124. In this example, voice devices on voice network 112 may include wireless smart phones 114, conventional wireless phones 116, wired telephones 118, netbooks 120 and smartbooks 122. Indeed, it is contemplated that the voice network may include a mobile music player device if it has Wifi connectivity. Each phone device is provisioned a phone number and some have the ability to display text and/or images in addition to transmitting voice. These phone devices also have the ability to access a data network using a data protocol such as TCP/IP. Both netbook 118 and smartbook 122 have general purpose computing capabilities but also have been provisioned with phone numbers from the voice network 112 and therefore can also transmit voice in addition to accessing data network 104.
The wireless phone provider of voice network 112 may implement any one or more different wireless protocols. Typically, most wireless providers use Global System for Mobile (GSM), Code Division Multiple Access (CDMA) or some variant compatible with one or more features of these technologies. Each of these and other wireless protocols support a data channel 124 that transmits text and data between phone devices using the SMS protocol. Due to limitations of voice network 112, SMS messages are limited to approximately 128 to 160 characters and managed entirely by the wireless phone provider of the voice network 112.
Little has evolved in the area of SMS messaging as access to these systems are proprietary and controlled by the wireless phone providers. In part, these efforts are an attempt by the wireless phone providers to protect the revenue stream generated by the per message fees and additional charges. Alternate protocols such as Multimedia messaging service (MMS) allows multimedia transmission in addition to text however suffer similar limitations within the voice network 112.
To address these and other limitations, aspects of the present invention allow much more robust communication while reusing the phone numbers provisioned from the voice network. Synthetic communication server 102 creates a connection between phone devices over the Internet and bypasses data channel 124. Phone devices registered on the synthetic communication network 100 may subscribe to improved text messaging and other data services across data network 104 in accordance with aspects of the present invention using their phone number provisioned on the voice network 112. In turn, users 124 of these registered phone devices have improved text messaging and other data services at lower or no per message costs. Instead of per message charges, phone devices would only have to subscribe to Internet access in order to reach data network 104 over bridge 110. The Internet access on these phones devices may use one or more different data plans incorporating technologies such as Enhanced Data Rates from GSM Evolution (EDGE), Universal Mobile Telephone Standard (UMTS), High Speed Downlink Packet Access (HSDPA) and Evolution Data Optimized (EVDO). Phone devices may also access data network 104 and the Internet using other wireless technologies such as WiMax, WiFi 802.11a/b/c/n/x or other similar protocols.
In one implementation, processor 206 executes instructions in memory 202 selected from one or more components including phone device verification and registration module 216, phone number normalization and synchronization module 218, message processing and routing module 220, multimedia processing and routing module 222, phone device status and notification module 224, and run-time module 228 that manages system resources used when processing one or more of the above components on system 200.
Phone device verification and registration module 216 verifies that a phone number has been provisioned to a phone device then registers the phone device on the synthetic communication network in accordance with implementations of the present invention. One verification module of the present invention retrieves the phone number directly from firmware on the phone device and performs the verification operations. Alternatively, the user of the phone device may supply the phone number for the phone device through a keyboard or other data entry device associated with the phone device. Aspects of the present invention first verify that the phone number is registered with the particular phone device before it can be registered on the synthetic communication network of the present invention. Over time, it may be necessary to verify a phone number more than once to ensure it is still associated with a particular phone device. In some cases, a phone number initially associated with one phone device may later be associated with a different phone device if the owner of the phone device cancels the voice service or changes providers. The phone number and corresponding phone device can be registered on the synthetic communication network in accordance with aspects of the present invention and begin transmitting data once it has been successfully verified.
Phone number normalization and synchronization module 218 normalizes the format of different phone numbers in a phone directory on the phone device to a predetermined standard. Implementations of the present invention process each phone number and consider how they should be modified and/or formatted. The normalized phone numbers preferably conform to an international telephone number (ITN) standard and incorporate a country code and other information to identify the ITN on a uniform basis.
The normalized phone numbers are used to synchronize the phone directory of phone numbers with registered phone numbers on the synthetic communication network of the present invention. If a phone number in the directory is also registered on the synthetic communication network then it is added or synchronized with entries in the synthetic communication client running on the phone device. This synchronization continues as new phone numbers are added to the phone directory and normalized phone numbers are added to the synthetic communication network.
Message processing and routing module 220 ensures messages from one phone device pass to another phone device in accordance with aspects of the present invention. The messages on the synthetic communication network use the normalized phone numbers to identify phone devices with particularity. Once identified, the routing module creates a network connection between the phone devices using a protocol such as TCP/IP. This message processing and routing module 220 generally passes text messages between phone devices registered on the synthetic communication network according to their previously verified and normalized phone numbers. In some implementations, messages processed by routing module 220 may operate in a compatibility mode and thus transmit one or more groups of 140 text characters. Alternatively, message processing and routing module 220 may indeed transmit a variable length of characters unlimited by the 140 characters of legacy SMS communication but instead dependent upon the length of the message being transmitted and capacities of the phone device sending or receiving the message.
Multimedia processing and routing module 222 operates in similar manner except that it processes a wider range of data types and may send images, video, sound or other data to a normalized phone number. Additional compression and encoding methods may be implemented on the multimedia processing and routing module 222 to effectively increase transmission bandwidth and decrease storage requirements.
Phone device status and notification module 224 enables phone devices to update their current status while tracking the status of other phone devices within the synthetic communication network. The synthetic communication client running on each phone device generally sends status updates to the synthetic communication servers. Likewise, the synthetic communication server sends updated status out to each of the phone devices tracking the status of the other phone devices. Aspects of the present invention also allows the synthetic communication client to determine the status of other members in their phonebook or directory without initiating a phone call, text message or even a separate communication session. For example, phone device status information may be obtained by accessing the synthetic communication servers holding the status in a status area on the servers.
Text messaging module 226 provides conventional text messaging functions used for phone number verification in accordance with aspects of the present invention. Conventional text messaging sends text messages to phone devices over a data channel portion of a voice network. Aspects of the present invention send a verification text message using text messaging module 226 to confirm that a phone number is associated with the particular phone device. In one implementation, text messaging module 226 subscribes to national and international SMS services to verify phone numbers nationally and internationally.
In general, the cluster of computers advantageously improves scalability through better overall utilization of resources and increases reliability as it is less likely for multiple computers to fail simultaneously. One implementation of this alternate system 300 may separate the different functions used in implementing aspects of the present invention onto different computers within the cluster of computers. For example, it is contemplated that six virtual machines may each be configured to execute phone device verification and registration server 302, normalization and synchronization server 304, message processing and routing server 306, multimedia processing and routing server 308, phone device status and notification server 310 and conventional text messaging server 312 on a cluster of three physical computers with virtualization technology. These different servers in alternate system 300 function in a similar manner as the aforementioned corresponding modules described in conjunction with and illustrated in
In one implementation, the synthetic communication client obtains the phone number and corresponding country code presumed to be associated with the phone device and used for communications over the synthetic communication network (404). The synthetic communication client running on the phone device may present a series of default options suggesting an international dialing prefix, a country code and a request that the user enter the phone number of the phone device. Typically, these options are suggested by the synthetic communication client based upon the country that the phone device is currently registered in. However, it is also possible that a user can override these suggested settings and enter their own country code, phone number and other information in the default options.
It is also possible for the client obtain the phone number from the phone device programmatically through an application programming interface (API). For example, the synthetic communication client may interface with an API that accesses an area of firmware on the phone device holding the phone number provisioned to the phone device when it was registered on the voice network. In this implementation, the phone number obtained through the API is automatically entered into the “phone number field” section of the synthetic communication client application. The user may decide to accept or modify the phone number in the “phone number field” suggested by the client. As such, it is also possible for the user to erase the suggested phone number entirely and specify a different phone number in the “phone number field” of the client as previously described.
Next, the synthetic communication client normalizes the phone number to a standard international telephone number (ITN) format taking into consideration the country code and other factors for use in the synthetic communication network (406). Normalizing the phone number to the ITN allows the synthetic communication network to uniquely identify the phone number and phone device on an international basis. Without normalization, it might be possible for two phone devices from different countries or areas to have identical phone numbers on the synthetic communication network. The normalized phone number ensures a country code and other fields are in the phone number thus greatly limiting or eliminating the possibility of duplicate phone numbers existing on the synthetic communication network. To avoid the potential conflict, the normalization process performed in accordance with the present invention makes sure each phone number adheres to the following ITN format:
Several operations may be performed in normalizing the phone number associated with the phone device. The synthetic communications client first attempts to incorporate the International dialing prefix “+” and “<CC>” and Country code to the phone number provided. Aspects of the present invention presumes that the phone number provided does not include the International dialing prefix of “+” (or its variants) or the country code and therefore adds them to the phone number. The country code defaults to the country code associated with the country where the phone has been registered or, alternatively, whatever country the user of the phone device specifies is the country of origin. The “+” symbol is added because it indicates that the country code and phone number will subsequently follow in sequence thereafter.
Second, the synthetic communications client may check for a few different conditions of the phone number. A lead-in character or characters may be added or removed from the start of the phone number. Some users may inadvertently add lead-in characters to their phone number out of habit to indicate access to local exchanges or other conditions. However, if a lead-in character is not meant to be part of the ITN then the client proceeds to remove the lead-in character from the phone number. For example, a lead-in character of “0” in a phone number in the United Kingdom indicates a local dialing prefix however it is not used in the ITN representation of a United Kingdom phone number. Accordingly, the synthetic communications client will remove the lead-in character “0” from a phone number when the country code associated with the United Kingdom (i.e., “44”) is indicated.
Alternatively, the voice network in certain countries may need to add a lead-in character to the phone number for a valid ITN. For example, in Mexico a leading “1” is generally inserted after the country code for Mexico (i.e., “52”) and before the phone number begins. The synthetic communication client of the present invention may therefore consider prepending a lead-in character of “1” to the phone number when the country code is “52” since few users would know to include this value in their phone number.
Third, aspects of the present invention may also check the length of the phone number to make sure it is the appropriate length for the country specified by the country code. If the length of the phone number is improper, the client may reject the phone number provided and indicate that it is either too long or too short in view of known acceptable phone numbers for the particular country. For example, a phone number having 15 digits may be rejected as longer than the accepted 10 digit numbers used in the United States. Once these and other checks are completed, the phone number for the phone device is considered normalized and the ITN representation of the phone number is ready for verification.
The verification operation ensures that the phone number originally provided to the synthetic communication client is indeed associated with the phone device. Conversely, if the phone number was invalid or associated with another phone device then the verification operation will indicate that the phone number (as well as the ITN representation of the normalized phone number) cannot be verified. Verification in one implementation of the present invention confirms the association between the phone number and the phone device by sending a round-trip verification message over a data channel of the voice network (408). In at least one implementation, the synthetic communication client creates a verification message embedded with text that uniquely identifies the verification message. For example, the embedded text may include a 3-digit randomly generated number to identify the message on its return trip back to the synthetic communication client. Both a “From:” or equivalent field and a “To:” or equivalent field in the verification message use the provided phone number presumed to be associated with the phone device.
In one implementation, the verification message may be sent from the synthetic communication client on the phone device using short messaging service (SMS) on the voice network. A successful return trip of the verification message back to the same synthetic communication client verifies the phone number in accordance with the present invention. Further details on the verification operation are described later herein in further detail. If the verification message does not return then there is an unsuccessful verification of the phone number and phone device association. (408-No) Accordingly, the synthetic communication client may deny the phone device and phone number access to synthetic communication network (410).
If the phone number association with the phone device is verified (408-yes) then the synthetic communication client receives authorization for the phone device to communicate over the synthetic communication network using the phone number from the voice network. In one implementation, a user of the newly added phone number and phone device can then communicate with other users who also have phone devices and phone numbers admitted to the synthetic communication network of the present invention. Thereafter, data is transmitted between phone devices on the synthetic communication network using each the respective phone number represented as a unique ITN.
The synthetic communication client offers to check if some or all of the phone numbers in a directory on the phone are also registered on the synthetic communication network. Users typically allow the synthetic communication client to check their phone directory as they want to communicate over the synthetic communication network with their current friends and associates. Accordingly, the synthetic communication client associated with the phone device is synchronized with entries in the phone directory from the phone device that are also members of the synthetic communication network (414). Each entry in the phone directory of the phone device is also checked for membership in the synthetic communication network. Aspects of the present invention also continue to update the synthetic communication client to include additional members of the synthetic communication network as new members join and as new phone numbers are added to the phone directory of the phone device.
Once synchronization is complete, aspects of the present invention can communicate messages with other members of the synthetic communication network through the synthetic communication client (416). Typical communication between members of the synthetic communication network is done over a data network such as the Internet using their respective normalized phone numbers having a country code and consistent with an international telephone number (ITN). The simplicity of reusing the phone numbers in their phone directory to communicate with other phone devices makes the synthetic communication network of the present invention compelling. Moreover, users of the synthetic communication network may use the phone number to send text messages over the Internet and not pay expensive per message charges for local and international text messaging over the data channel of their voice network.
Aspects of the present invention determine if one or more directory entries from a phone device can receive communications over the synthetic communication network using the directory entry's phone number (502). To make such a determination, each phone number in the phone directory of the phone device is compared with registered phone numbers on the synthetic communication network. Making the comparison further involves normalizing phone numbers from the directory in the same manner as registered phone numbers on the synthetic communication network. (504) For example, the normalized version of a phone number from the directory should include a country code and be formatted consistent with an international telephone number (ITN) format. Details on normalizing one or more phone numbers in accordance with aspects of the present invention are described in further detail later herein.
Next, a comparison determines whether the normalized phone number from a directory entry match a normalized phone number registered with the synthetic communication network (506). A match between a normalized phone number from the directory and a normalized phone number registered on the synthetic communication network indicates that the phone number from the directory is also a member of the synthetic communication network. The match does not consider details such as a person's name, address, company or other personal information. Since these details are not part of the comparison and determination, they need not be stored on or sent to the synthetic communication server. Thus, if there is a match between the two normalized phone numbers (506-Yes) then aspects of the present invention returns the normalized phone number and indicates that the phone number from the directory is a member of the synthetic communication network. The phone device corresponding to the phone number can be used to exchange messages over the synthetic communication network using the normalized phone number (508). Storing the normalized phone number synchronizes the synthetic communication client with the phone number entries in the directory on the phone device. This synchronized list of normalized phone numbers is used by the synthetic communication client to communicate with other phone devices over the new synthetic communication network.
When the normalized phone number from the directory does not match (506-No), aspects of the present invention may still provide the normalized phone number to the synthetic communication client but indicate that the normalized phone number is not yet registered on the synthetic communication network (510). Likewise, the client may synchronize the normalized phone numbers but will indicate on the graphical user interface (GUI) that the phone number cannot be used to send messages over the synthetic communication network. For example, the GUI of the synthetic communication client may display the name of the person, the corresponding normalized phone number and an icon that the particular number is not yet registered on the synthetic communication network of the present invention. If the normalized phone number subsequently does register, then a different icon on the GUI of the synthetic communication client will indicate that the number is registered and can communicate on the synthetic communication network. Information on the person's name, address, company or other details is generally obtained by cross referencing a normalized phone number with phone numbers from the directory on the phone device. For privacy reasons, the synthetic communication server may leave all personal information within the directory of the phone device and only store normalized phone numbers registered on the synthetic communication network.
In one implementation, a synthetic communication server receives one or more phone numbers from the phone directory on the phone device and performs the normalization on behalf of the synthetic communication client. Initially, the synthetic communication server receives a default country code and at least one phone number from the phone directory to be transformed into a normalized phone number with international dialing prefix and country code (602). A suggested default country code generally corresponds to the country associated with the voice network where the phone number and phone device were provisioned. In some cases the default country code of the phone device may be modified by the user of the synthetic communication client to accommodate a different country and country code.
Implementations of the present invention first check whether the phone number starts with an international dialing prefix or equivalent (604). For example, a phone number from the phone directory of a phone device registered in the United Kingdom may be entered as +44 2710 5566. If the “+” symbol is included in a phone number (604-Yes) then aspects of the present invention presumes that the international dialing prefix is followed by a subsequent country code and phone number and in a proper international telephone number (ITN) format as previously described.
Depending on the country code, aspects of the present invention may also replace an alternate international dialing prefix such as a “011” in the United States with the universal international dialing prefex “+”. Accordingly, the synthetic communication server may use the phone number without modification if the international dialing prefix is the leading character to the phone number as provided (606).
Next, aspects of the present invention determine if the first few characters of the provided phone number also happen to match the default country code provided (608). If the default country code appears in the first characters (608-Yes) then it is presumed that the phone number includes a country code but is missing an international dialing prefix. Consistent with aspects of the present invention, the synthetic communication server adds an international dialing prefix to the phone number from the phone directory (610).
Alternatively, if the first characters do not match the default country code then aspects of the present invention may determine whether lead-in characters to the phone number need to be added, removed or modified in view of the default country code (612). When the lead-in characters of the phone number need modification (612-Yes) then the synthetic communication server modifies lead-in characters to phone number in order to comply with format and dialing requirements of ITN in view of default country code (614). As previously described, some users may add lead-in characters to phone numbers in their phone directory out of habit or to indicate access to local exchanges or other conditions. If the lead-in character is not meant to be part of the ITN then the normalization process on the server proceeds to remove the lead-in character from the phone number. For example, a lead-in character “0” on the phone number in the United Kingdom may indicate a local dialing prefix however it is not used in the ITN representation of a United Kingdom phone number. Accordingly, the server will remove the lead-in character “0” from a phone number when the default country code provided is the United Kingdom (i.e., “44”).
Conversely, voice network in other countries may need a lead-in character added to a phone number to create a valid ITN. For example, in Mexico a lead-in character “1” may be inserted after the country code for Mexico (i.e., “52”) and before the start of the phone number. The synthetic communication client of the present invention therefore may prepend a lead-in character of “1” to the phone number when the default country code is 52 as few users might know to include this value in their phones number when dialing internationally.
Additionally, aspects of the present invention may then add both the international dialing prefix and default country code to the phone number obtained from the phone directory. For example, the synthetic communication server of the present invention prepends a phone number with a “+44” when the default country is United Kingdom and no international dialing prefix or country codes are detected in the first portion of characters from the phone number (616).
Once normalized, aspects of the present invention provide a normalized version of the at least one phone number from the phone directory and indicates if a phone number is also a member of the synthetic communication network (618). For efficiency, one implementation of the synthetic communication server may receive and process a group of the phone numbers in a single request. Similarly, the resulting set of one or more normalized phone numbers may be sent back to the synthetic communication client in one transmission. It is advantageous for the synthetic communications server to keep copies of all the normalized phone numbers from each phone device and phone directory. For example, the synthetic communications server may be able to determine if a phone device and phone number are already members of the synthetic communication network by simply comparing the normalized phone number with other previously registered phone numbers and ITN values.
It should be appreciated that membership in the synthetic communication network may be determined using only the phone numbers normalized in accordance with implementations of the invention. Normalized phone numbers stored by the synthetic communication server include country code information and identify the corresponding phone device on an international basis. Registering as a member of the synthetic communication network therefore only requires providing an ITN and not providing any personal information that other communication networks might require, such as a login or username.
Accordingly, one implementation of the present invention attempts transmission of a verification data message from the phone device through a data channel within the voice network and back to the phone device using the unconfirmed phone number (704). In one implementation, the data channel of the voice network allows the verification data message to be up to 140 characters using a short messaging service (SMS). A synthetic communication client executing on the phone device may randomly generate the verification data message up to this character limit and prepare to send it over the data channel using the phone number presumed associated with the phone device. For example, the SMS message may address the phone device using the presumed phone number and include the randomly generated message for verification purposes.
Next, aspects of the present invention determine if the verification message was subsequently received by the phone device over the voice network (706). One embodiment of the present invention uses the synthetic communication client executing on the phone device to compare the original outbound verification data message with the returning verification data message. If the verification data message returned to the synthetic communication client matches then aspects of the present invention have independently verified and confirmed that the phone number is associated with the phone device as presumed (706-Yes). For example, the verification data message may be include randomly generated 3-digit value sent out as an SMS message that loops back and returns to the synthetic communication client executing on the phone device. The synthetic communication client verifies the phone number of the phone device when the 3-digit value received by the synthetic communication client of the present invention matches the 3-digit value sent out.
Once confirmed, aspects of the present invention indicate the unconfirmed phone number should be identified as a confirmed phone number associated with the phone device (710). The confirmed phone number can be used reliably on the synthetic communication network as the phone number has been successfully and independently verified. Repeated verification may be performed at regular intervals to make sure the phone number has not been disconnected, abandoned or reassigned to a different phone device over time. In general, verification ensures that the phone devices will be able to communicate with each other on the synthetic communication network as expected.
If the phone number can be confirmed then aspects of the present invention authorizes communication with the phone device over the synthesized communications network using the confirmed phone number (712). Alternatively, if the predetermined data message returned to the synthetic communication client does not match (706-No) then aspects of the present invention indicate that the unconfirmed phone number cannot be confirmed and used as a phone number associated with the phone device and the phone number are not registered (708).
Aspects of the present invention receive an unconfirmed phone number provisioned from a voice network and presumed to be associated with a phone device (802). The phone device may be a wireless phone as well as any other device that is assigned a phone number on the voice network. It is necessary for the synthesized communication network to independently verify the association of the phone number on the phone device before it can be reliably reused for the synthetic communication network. This is at least because phone numbers are provisioned and managed on the voice network but reused on the synthetic communication network of the present invention.
Accordingly, one implementation of the present invention attempts transmission of a verification message from the phone device through a data channel within the voice network and back to the phone device using the unconfirmed phone number (804). In one implementation, the data channel of the voice network allows the verification message to be up to 140 characters using a short messaging service (SMS). A synthetic communication client executing on the phone device randomly generates the verification message up to this character limit and prepares to send over the data channel using the phone number presumed associated with the phone device. For example, the SMS message may address the phone device using the phone number presumed to be associated with the phone device and include the randomly generated verification message for subsequent comparison.
Next, aspects of the present invention determine if the predetermined message was subsequently received by the phone device over the voice network (806). One embodiment of the present invention uses the synthetic communication client executing on the phone device to compare the original outbound verification message with the returning message. If the message returned to the synthetic communication client matches the verification message then aspects of the present invention have independently verified and confirmed that the phone number is associated with the phone device as alleged (806-Yes). For example, the verification message may be a randomly generated 3-digit value sent in an SMS message that loops back and returns to the synthetic communication client executing on the phone device. Essentially, the confirmed phone number can continue to be used reliably on the new synthetic communication network as the phone number has been successfully and independently re-verified. This ensures that the phone devices are able to communicate with each other over the synthetic communication network as expected.
Once confirmed, aspects of the present invention indicate that the phone number should continue to be identified as a confirmed phone number associated with the phone device (808). Repeated verification may be performed at regular intervals to make sure the phone number has not been disconnected, abandoned or reassigned to a different phone device over time.
Alternatively, if the verification message returned to the synthetic communication client does not match (806-No) then aspects of the present invention indicates that the unconfirmed phone number should no longer be used as a phone number associated with the phone device on the synthetic network in accordance with the present invention (810).
One implementation of the present invention consistent with the GUI of phone device 902 depicts a set of normalized phone numbers being monitored. A status list on the synthetic communication client tracks the status of phone devices and displays the status as indicated by status 904a-h. For example, a user may set the status to indicate a specific activity illustrated in status 904b such as “Studying physics” or may indicate a general status such as status 904f indicating “Busy . . . ”. Status on the synthetic communication is flexible and can be set to anything the user wants to indicate.
These normalized phone numbers 908a-h also show a user name (First Name Last Initial) and the normalized phone number formatted with both an international dialing prefix and country code. The synthetic communication client of the present invention may be used to manage and display these users and their normalized phone numbers once they are synchronized in accordance with aspects of the present invention as previously described. Additional information may include a corresponding icon or photo 906a-906h chosen by the phone device being monitored.
In one implementation, a synthetic communication server receives a message with a normalized phone number identifying a target phone device and updated status of the target phone device on a synthetic communication network (1002). Status may indicate that the user of the phone device is currently busy, on a plane, that the phone has actually been turned off or any status message the user of the phone device wishes to provide. Generally, the user enters status information on a synthetic communication client executing on the target phone device. The synthetic communication client transmits the updated status of the phone device by sending a status message over the synthetic communication network to the synthetic communication server.
Aspects of the present invention store the updated status of the target phone device in a status area referenced by the normalized phone number of the target phone device (1004). Entries in the status area also hold the current status of each phone device on the synthetic communication network along with their corresponding normalized phone numbers. Next, the synthetic communication server of the present invention determines if a subset of phone devices from a set of one or more other phone devices on the synthetic communication network is interested in the status of the target phone device (1006). To make this determination, the synthetic communication server downloads a status list from each phone device listing the phone devices to be monitored. The server compares the normalized phone number of the target phone device against normalized phone numbers in the status list from each of the phone devices. Matches from these comparisons determine the subset of phone devices interested in the status of the target phone device.
If the target phone device is being monitored then aspects of the present invention push the updated status of the target phone device to the subset of phone devices and the status list on each phone device (1008). For example, the updated status may be sent to each phone device in the subset through a status update message sent over the synthetic communication network. Individual phone devices process the status updates for target phone device and other phone devices then display the results in a GUI such as the one depicted in
The phone device generally sends the status list and an updated status of the individual phone device in a message that includes a normalized phone number that specifically identifies the phone device on the synthetic communication network (1104). For example, a phone device may send the status list of normalized phone numbers in response to a request for the status list from a synthetic communication server. The synthetic communication server receives the updated status of the phone device and updates the appropriate entry in the status area of the synthetic communication server. In addition, the synthetic communication server may also receive the status list of other phone devices being monitored by the phone device.
Next, aspects of the present invention receive the status updates of the other phone devices in the status list referenced using the corresponding normalized phone numbers for each of the other phone devices (1108). In one implementation, the synthetic communication client running on the phone device updates the status list with the status updates of the other phone devices. The phone device may then display the status updates of the one or more other phone devices on the synthetic communication network in a display area of the phone device (1108). One implementation of the present invention may display the status of other phone devices as illustrated in accordance with
While examples and implementations have been described, they should not serve to limit any aspect of the present invention. Accordingly, implementations of the invention can be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them. Apparatus of the invention can be implemented in a computer program product tangibly embodied in a machine readable storage device for execution by a programmable processor; and method steps of the invention can be performed by a programmable processor executing a program of instructions to perform functions of the invention by operating on input data and generating output. The invention can be implemented advantageously in one or more computer programs that are executable on a programmable system including at least one programmable processor coupled to receive data and instructions from, and to transmit data and instructions to, a data storage system, at least one input device, and at least one output device. Each computer program can be implemented in a high level procedural or object oriented programming language, or in assembly or machine language if desired; and in any case, the language can be a compiled or interpreted language. Suitable processors include, by way of example, both general and special purpose microprocessors. Generally, a processor will receive instructions and data from a read only memory and/or a random access memory. Generally, a computer will include one or more mass storage devices for storing data files; such devices include magnetic disks, such as internal hard disks and removable disks; magneto optical disks; and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including by way of example semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto optical disks; and CD ROM disks. Any of the foregoing can be supplemented by, or incorporated in, ASICs.
While specific embodiments have been described herein for purposes of illustration, various modifications may be made without departing from the spirit and scope of the invention. For example, a predetermined data message containing text characters can be sent over a data channel portion of the voice network as a verification message for a phone number and phone device. However, alternate methods of confirming a phone number may include sending a voice message to a phone number and then verifying the receipt of the voice message on the phone device with a return voice message. Accordingly, the invention is not limited to the above-described implementations, but instead is defined by the appended claims in light of their full scope of equivalents.
