Abstract:
An alias can be used to access address book information across multiple communication applications. The alias can also be a screen name, for example, an instant messenger screen name. However, the alias can be used to access more than just instant messenger contact information; it can be used to access other information, including telephone numbers, SMS, EMS and MMS contact information as well as instant messenger contact information. Additionally, the single alias can be used to access instant messenger contact information across multiple instant messenger services. An alias can be assigned that is easy to remember; for example, it can be a shortened version of the contact&#39;s name, or a nickname.

Description:
BACKGROUND  
       [0001]     1. Field of the Invention  
         [0002]     The field of the invention relates generally to mobile communication devices and more particularly to managing contact information for a plurality of communication applications running on a mobile communication device.  
         [0003]     2. Background Information  
         [0004]     Conventional mobile communication devices, such as cellular telephones and Personal Digital Assistants (PDAs) with communication capability, can be configured to support a variety of communication applications, or services, including, for example, voice communication services, Short-Message-Service (SMS), Enhanced Message Service (EMS), Multimedia Messaging Service (MMS), and Instant Messaging (IM). Conventional mobile communication devices often include an “address book” to keep track of contact information for a plurality of contacts; however, maintaining contact information for a large number of contacts can become unwieldy, making conventional address books difficult to use.  
         [0005]     This problem is compounded when a mobile communication device is configured to support multiple communication applications, because each contact can potential be associated with a different contact identifier for each communication application. For example, each contact can have a unique telephone number, SMS address or identifier, IM address or identifier, etc. Accordingly, conventional address books can become filled with enough information that they are difficult to navigate and use.  
         [0006]     Conventional address books typically provide several navigation methods. For example, the user can scroll through each entry one entry at a time. Such an approach is generally manageable when the address book is small, but quickly becomes unmanageable, or at least time consuming, as the address book grows. In many cases the user can also enter a letter, for example, the first letter of a last name, to limit the number of entries that must be subsequently searched. This can still be time-consuming for long lists. A user can sometimes enter more characters to further limit the number of entries to be searched, even zeroing in on the precise entry. This can require that several characters be entered to select a contact.  
         [0007]     A “speed dial” approach can also be used to allow quick access to entries in an address book. In such an approach, a contact is associated with a defined storage location. For example, a communication device can have perhaps 1 to 99, or more, defined storage locations for this purpose. A user can then access a contact by entering an identifier, such as a number, that identifies the associated storage location. A drawback to this approach, however, is that a typical user can only remember the storage identifier for a relatively small number of contacts. Thus, the user ends up scrolling through the speed dial locations anyway.  
       SUMMARY OF THE INVENTION  
       [0008]     One way to quickly access address book information is through the use of aliases. An alias can be assigned that is easy to remember; for example, it can be a shortened version of the contact&#39;s name, or a nickname. The alias can also be a screen name, for example, an instant messenger screen name; however, the alias can be used to access more than just instant messenger contact information. For example, the alias can be used to access address book information, including telephone numbers, SMS, EMS, IM and MMS contact information.  
         [0009]     In one aspect, a single alias can even be used to access IM contact information for multiple IM services.  
         [0010]     These and other features, aspects, and embodiments of the invention are described below in the section entitled “Detailed Description.”

     DETAILED DESCRIPTION  
       [0019]     In the systems and methods described below, an alias is associated with contact entries in an address book included in a communication device. The alias can then be used to access the appropriate contact identifier for a specific communication application. For example, if a user of a mobile communication devices is trying to send an SMS message to a specific contact, then the alias can be used to select the contacts SMS address. The aliases are provided by the user and can, therefore, be easier to remember than, e.g., a speed dial location. Moreover, a single alias can be used to select the appropriate contact identifier for each communication application supported.  
         [0020]     For purposes of this specification and the claims that follow, the term contact identifier is intended to refer to the number, address, or other identifier used to establish a communication with the contact using a given communication application (e.g, a telephone number, SMS number, email address, etc.).  
         [0021]      FIG. 1  is a diagram illustrating an address book  100  configured in accordance with one embodiment of the systems and methods described herein. As can be seen, address book  100  comprises a plurality of contact entries  102 . Contact entries  102 , can for example, comprise contact information such as the name of the contact, address, business, title, etc., as with many conventional address books. Further, each contact entry can contain one or more contact identifiers for the associated contact. In addition, however, an alias  104  is associated with each contact entry  102 . Alias  104  can be a moniker that is associated with the contact by the user. Alias  104  can, for example, be a name, nickname, initials, abbreviation, screen name, etc. Preferably, an alias  104  associated with a specific contact will be easy to remember.  
         [0022]     Generally, each contact entry  102  is associated with a single alias  104 ; however, depending on the embodiment, a contact can be associated with a plurality of aliases  104 . A single alias  104  can also be associated with more than one contact entry  102 . Additionally, in certain embodiments, certain contact entries  102  may not be associated with an alias  104 .  
         [0023]     Thus, the contact entry  102 —alias  104  association generates an association between the contact identifiers included in the contact entry and the associated alias. This is illustrated in the diagram of  FIG. 2 . As can be seen, the contact entry  102  can include a plurality of contact identifiers  202 . These can include a home telephone number, mobile telephone number, work telephone number, IM identifier, SMS contact identifier, EMS contact identifier, MMS contact identifier, etc. In many embodiments, contact identifiers  202  will only include identifiers for communication applications supported by the associated communication device; however, in certain embodiments, contact identifiers for unsupported communication applications can also be stored in contact entry  102 . Each of these contact identifiers  202  is associated with the corresponding alias  104 . The association between contact identifiers  202  and alias  104  can allow for quick access to contact information and identifiers as described in detail below.  
         [0024]     It will be appreciated that there are many methods by which the alias information can be entered and associated with a contact entry. For example, the user can be allowed to enter the aliases into the user&#39;s communication device when the user is entering other contact information. In certain embodiments, a software program running on a computer can be used to enter and manage contact and alias information, which can then be downloaded to the communication device.  
         [0025]      FIG. 3  is flow chart illustrating an example method for using an alias for establishing a communication from the perspective of a communication device in accordance with one embodiment of the systems and methods described herein. First, the communication device can be configured to initiate a communication application, in step  302 , in response to an action taken by the user. For example, the user can activate an SMS application supported by the communication device. This will cause the communication device to launch the SMS application and wait for a SMS identifier to be entered in to the device.  
         [0026]     Instead of entering an SMS identifier, however, the user can input an alias, which will be received by the device in step  308 . The alias can, for example, be input through a user interface associated with the communication device. The device can then map the alias provide in step  304  to the associated contact entry in step  310 . The device can be configured to then determine and select the appropriate contact identifier  202 , e.g., the associated SMS identifier, in step  312 . In other words, the SMS application, or a software program or application configured to run on the communication device, can be configured to scroll through the contact identifiers associated with the corresponding contact entry and select the one the corresponds to, or is appropriate for, the SMS application. Other method for determining or retrieving the appropriate contact identifier may also be used. For example, a function may be defined that retrieves the appropriate contact for the address book data using an application (or application identification) and an alias (or alias identification).  
         [0027]     If the communication application selected is a data application, such as an SMS application, then the user can, prior to entering the alias, enter the data, or message, to be transmitted in step  304 . In alternative embodiments, or implementations, the data can be entered after the alias is entered (step  308 ) and the associated contact identifier is selected (step  312 ). If the application is a data application, then the data can be sent in step  316 , once the contact identifier, e.g., SMS identifier, is selected. But if the application is a voice application, for example, then a connection can be made, e.g., a call can be placed, using the selected contact identifier in step  318 .  
         [0028]     In certain instances, a contact can have multiple contact identifiers for a given communication application. For example, a contact can have multiple telephone numbers as illustrated in  FIG. 3 . A user can also have multiple identifiers for other communication applications.  FIG. 4 , for example, illustrates the situation where multiple IM identifiers  402  and  404  are associated with a single contact and alias  104 . Two IM identifier are illustrated in  FIG. 4  by way of example only. It will be understood that more than two identifiers for a given communication application can be associated with a single alias, such as the the three telephone numbers in  FIG. 3 . In such situations, the user can be prompted to select the appropriate identifier.  
         [0029]     On example method for prompting the user to select one of multiple contact identifiers associated with the same communication application is illustrated by the flow chart of  FIG. 6 . In  FIG. 6 , once it is determined that there are multiple contact identifiers associated with the contact for the selected communication application, the user can be prompted to select the appropriate identifier in step  602 . For example, the contact identifiers can be displayed on a display associated with the communication device. The user can then select the appropriate identifier, e.g., by scrolling to the appropriate identifier or entering a number associated with the appropriate identifier, which will be received in step  604 . The selected identifier can then be associated with the outgoing message or communication in step  606 , which can then be sent or initiated in step  608 .  
         [0030]      FIG. 5  is a flow chart illustrating an example method for using an alias to respond to, or forward a message, or incoming communication, in accordance with one embodiment of the systems and methods described herein. In step  502 , a message, or incoming communication, is received. The user can then select to activate the communication application associated with the message so that the user can view or hear the message. This will cause the communication device to initiate the communication application in step  504 . The user can then select to respond to, or forward the message in step  506 , which can cause the application to prompt the user for an alias in step  508 .  
         [0031]     In one embodiment, the contact identifier associated with the received message can appear as a default alias when the user elects to forward or respond to the message. If the user wants to send the response to another party, an additional party, or if no default is used, then the user can enter the appropriate alias in step  510 . In step  512 , the alias can be mapped to the appropriate contact entry and the appropriate contact identifier can be selected from contact identifiers  202 .  
         [0032]     The user can be prompted repeatedly until the user has entered the aliases associated with all contacts to which the user desires to forward the message. Once the user is done entering aliases, the message can be forwarded in step  514 . But first, the user can be given the option to enter further data, such as a reply message, in step  516 , depending on the embodiment and the type of communication involved.  
         [0033]     It will be appreciated that the prompt of step  508  can be for a contact identifier, to which the user instead responds with an alias. Accordingly, the device should be configured to recognize an alias, from a contact identifier, and map it to the associated contact entry.  
         [0034]     Certain communication applications can incorporate voice recognition. In such instances, the voice recognition component can be trained on the aliases associated with the contact entries. For example, after activating a particular communication application, the user can speak the alias into the device, cause in the device to map the alias to the appropriate contact entry and retrieve the appropriate contact identifier.  
         [0035]      FIG. 7  is a diagram of a mobile communication device  700  configured to implement the systems and methods described above. As can be seen, in the example of  FIG. 7 , device  700  includes an antenna  702  and a radio  704 . Radio  704  can be configured to modulate signals to be transmitted with a carrier frequency and transmit them via antenna  702 . Radio  704  can also be configured to demodulate signals received via antenna  702 . Processor  706  can be configured to process the transmit and receive signals.  
         [0036]     Processor  706  can comprise multiple processors or processing circuits, such as Digital signal Processors (DSPs), audio processors, math coprocessors, etc. These processors and/or processing circuits can be included in a single Integrated Circuit (IC), or several ICs, and can be packaged in a single chip package or multiple chip packages. Radio  704  can be any standard or customized radio configured to transmit signals wirelessly over the air. Antenna  702  can comprise a single or antenna or multiple antennas, e.g., for spatial diversity. In fact antenna  702  can actually comprise one or more arrays of antennas.  
         [0037]     Device  700  can also include a memory  714  coupled with processor  706 , which can be configured to store instructions  718  and data that can be used by processor  714  to control the operation of device  700 . In addition, memory  714  can be configured to store an address book  720 , which can comprise contact information and associated aliases as described above. Memory  714  can also store applications such as communication applications  716 , which can include, e.g., a SMS application, MMS application, EMS application, IM application, etc. Memory  714  can also store alias program  712 .  
         [0038]     Thus, a user can cause one of the communication applications  716  to be launched (step  302 ), e.g., via commands entered through a user interface  710  coupled with processor  706 . Once launched, the select communication application can then prompt the user for a contact identifier, e.g., the application can cause a prompt to be displayed on display  708 . The user can, in response to the prompt, input an alias (step  308 ), e.g., through user interface  710 . Alias program  712  can be configured to then recognize that an alias was provided, map the alias to the corresponding contact entry (step  310 ) in address book  720 , and select the appropriate contact identifier (step  312 ). The selected communication application can then send, or initiate, a communication using the contact identifier (step  316 ).  
         [0039]     Alias program  712  can actually comprise part of the communication applications  716  or can be an overlay that works in conjunction with each of communication applications  716 .  
         [0040]     It should be noted that memory  714  can be one or multiple device contained in one ore multiple circuit packages. For example, memory  714  can include static or dynamic memory, erasable memory, removable memory, etc.  
         [0041]     While certain embodiments and/or implementations of the inventions have been described above, it will be understood that the embodiments described are by way of example only. Accordingly, the inventions should not be limited based on the described embodiments. Rather, the scope of the inventions described herein should only be limited in light of the claims that follow when taken in conjunction with the above description and accompanying drawings.
