Directory assistance service based on context identifier

## Abstract

Methods and systems are disclosed for providing context information pertaining to a request of a directory assistance operator service based on a context identifier. The context identifier permits the directory assistance operator service to obtain context information including a location of the user and a location relevant to a directory listing search. The context identifier also can be used to pass context information or directory listing information across multiple types of user devices that use different types of services including a television service, a mobile service, a landline telephone service, and Internet service, and third party devices to permit enhanced directory assistance services to be provided to the user.

## Background
BACKGROUND
Directory Assistance (DA) is a service that provides users the ability to obtain the phone number and address of a person or entity (e.g., a business, a government office, etc.). Traditionally, users access directory assistance through their landline by dialing 411 or 1-area code-555-1212. More recently, users may access directory assistance via mobile applications.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. Also, the following detailed description does not limit the invention.
According to an exemplary embodiment, a directory assistance operator service uses a context identifier to obtain context information pertaining to a directory assistance request from a user. For example, the context identifier may serve as a pointer or a key to the context information.
According to an exemplary embodiment, the directory assistance operator service may provide directory assistance across multiple services (e.g., television service, mobile service, telephone service (e.g., landline), and Internet service) based on the context identifier. The directory assistance operator service may also provide directory assistance that are device-type specific (e.g., in terms of user device capabilities and user interfaces associated with a user device).
According to an exemplary embodiment, a directory assistance network may receive a directory assistance request from a user via a user device associated with a particular service (e.g., a television service, a mobile service, Internet service). According to an exemplary implementation, the directory assistance request includes context information. For example, the context information may include city information, state information, a name, an address, a business category, and/or a search query term(s). The directory assistance network extracts the context information from the directory assistance request and stores the context information. Additionally, the directory assistance network generates a context identifier and stores the context identifier. The context identifier may take the form of a string (e.g., a numeric string, an alphanumeric string, a character string, etc.). The context identifier may be unique relative to other context identifiers generated and stored.
According to an exemplary embodiment, a directory assistance operator network may permit directory assistance operators to service directory assistance requests. The context identifier may permit context information to be made available to the directory assistance operator. For example, based on the context identifier, context information may be populated on a user interface of a user device used by the directory assistance operator to service the directory assistance request. In this way, the user requesting directory assistance does not need to vocally repeat and/or re-enter the context information for the directory assistance operator. Additionally, the context identifier may permit not only the directory assistance operator service to access and use the context information but also other types of enhanced services (e.g., navigational services, obtaining coupons, etc.) to be offered to the user. For example, the context identifier may permit various user devices that operator on different platforms and/or service levels (e.g., mobile service, Internet service, television service) to exploit the context information and offer services to the user, which are user device appropriate.

For example, network device 160 may include a database management system that supports, among other things, a data model and a query language, and controls data access, data integrity, etc., relative to a database or a data structure.
FIGS. 1B-1D illustrate an exemplary messaging diagram pertaining to an exemplary scenario in which directory assistance service(s) may be provided. According to this scenario, assume a user is watching user device 140 (e.g., a television) and wishes to find information about a business. The user launches a 411 widget displayed on his/her user device 140 and a graphical user interface (GUI) is displayed to allow the user to search for directory assistance information, as illustrated in step (1). For example, the GUI may permit the user to search by category (e.g., automotive, etc.) and by name (e.g., business name, a person's name). The GUI may also permit the user to set user preferences (e.g., search radius, mobile telephone preference (e.g., the user's mobile telephone number), location preference (e.g., city, state, zip code)).
The user enters a search query via the 411 widget GUI. The 411 widget generates a directory assistance (DA) request that includes the search query and transmits the directory assistance request via user device 140 to television network 110, as illustrated in step (2). Television network 110 (e.g., a television network device, such as a server device) receives the directory assistance request. The television network device searches a directory assistance database. Television network 110 generates a directory assistance response based on the search result, as illustrated in step (3), and transmits the directory assistance response to user device 140, as illustrated in step (4).
According to this scenario, assume that the user reviews the search results included in the directory assistance response and is not satisfied. The user then decides to select a directory assistance operator icon to receive directory assistance operator service, as illustrated in step (5). The directory assistance operator application (e.g., included in the directory assistance application, such as the 411 widget) generates a directory assistance request that includes context information and transmits, via user device 140, the directory assistance request to directory assistance network 125, as illustrated in step (6). In this example, the context information may include city, state, and zip code pertaining to the location of the user, the search query, search result, and the city, state, and zip code associated with the search query. User device 140 may obtain portions of the context information from one or more files that is/are created and stored during runtime of the directory assistance application, from user preference information, and/or from information included in the directory assistance response in step (4). When the directory assistance request is received by directory assistance network 125 (e.g., network device 160), network device 160 stores the context information (e.g., in a context database), generates a context identifier, and stores the context identifier in the context database, as illustrated in step (7).
Referring to FIG. 1C, directory assistance network 125 transmits a directory assistance response that includes the context identifier to user device 140, as illustrated in step (8). The directory assistance operator application receives the context identifier and generates a directory assistance operator request, as illustrated in step (9). The directory assistance operator application, via user device 140, transmits the directory assistance operator request that includes the context identifier to directory assistance operator network 130, as illustrated in step (10). Directory assistance operator network 130 (e.g., a directory assistance operator network device, such as a gateway device or a server device) receives the directory assistance operator request. The directory assistance operator network device extracts the context identifier from the directory assistance operator network request and generates a context information request, as illustrated in step (11). According to another implementation, user device 155 may receive the directory assistance operator request, generate a context information request, etc., instead of directory assistance operator network 130, so as to obtain the context information in a manner similar to the directory assistance operator network device, as described herein.
Referring to FIG. 1C, the directory assistance operator network device transmits the context information request to directory assistance network 125, as illustrated in step (12). As further illustrated in FIG. 1C, directory assistance network 125 (e.g., network device 160) receives the context information request and retrieves the context information from the context database based on the context identifier, as illustrated in step (13). Network device 160 generates a context information response that includes the retrieved context information and transmits the context information response to directory assistance operator network 130. Directory assistance operator network 130 transmits the context information response to user device 155, as illustrated in step (14).
Referring to FIG. 1D, according to this scenario, a directory assistance operator receives the directory assistance operator response information. For example, user device 155 includes a directory assistance operator application in which the context information is automatically obtained. For example, the directory assistance operator application may automatically populate the context information in one or more graphical user interfaces for the directory assistance operator. In this way, the user does not have to re-provide this information to the directory assistance operator.
According to this scenario, the directory assistance operator initiates a telephone call to the user via telephone network 120 and user device 150, as illustrated in step (15). Alternatively, the directory assistance operator initiates a telephone call to the user via mobile network 105 and user device 135. The user is prompted via the 411 widget GUI of an incoming call from the directory assistance operator. According to this scenario, the user subscribes to television service, mobile service, and landline telephone service from a common service provider. The user accepts the call from the directory assistance operator on user device 150 (e.g., a landline telephone).
The directory assistance operator and the user converse. The directory assistance operator retrieves directory assistance information that the user desires. During the conversation, the user requests that the directory assistance operator send the directory assistance information (e.g., a listing) to the user's mobile device (e.g., user device 135) because the user plans to travel to the business.
As illustrated in FIG. 1D, user device 155 generates a directory assistance operator response that includes the directory assistance information (e.g., a listing of a business, with address, business hours, and telephone number), as illustrated in step (16). User device 155 transmits the directory assistance operator response to user device 135 via mobile network 105, as illustrated in step (17).
Mobile network 105 may communicate the directory assistance operator information to user device 135 using some form of electronic communication (e.g., e-mail message, Short Messaging Service (SMS) message, Multimedia Messaging Service (MMS) message, Instant Message (IM) message, Wireless Application Protocol (WAP) Push Message, etc.). User device 135 may include an electronic communication application to receive the directory assistance operation information.
According to an exemplary implementation, the electronic communication application may prompt the user for additional services pertaining to the directory assistance operator information. For example, the user may be prompted whether he/she would like navigational services (e.g., driving directions, etc.), coupons, user ratings of business or better business bureau (BBB) information, web site information, etc. Depending on, for example, the capabilities of user device 135 (e.g., applications installed, whether user device 135 is a smartphone, etc.) and/or the enhanced services requested by the user, user device 135 may provide such enhanced service, access other networks (e.g., Internet 115), generate and send service requests (e.g., to a third party service, a mobile network service, etc.), as illustrated in step (18), and receive enhanced information (e.g., coupons, etc.) and/or enhanced services, as illustrated in step (19), pertaining to the directory assistance operator information. According to other implementations, the directory assistance operator information may include enhanced information.

As previously described, network device 160 receives context information and generates a context identifier, as illustrated in FIG. 3A. According to an exemplary embodiment, the context identifier may be a unique string. Alternatively, the context identifier may include a unique string and one or more other fields that provide information relevant to providing directory assistance. For example, as illustrated in FIG. 3B, a context identifier 305 may include a type of service field 310 and a unique string field 315.
The type of service field 310 may indicate the type of service used by the user to invoke the directory assistance request. For example, the type of service field 310 may indicate whether the user invokes directory assistance via a television service, a mobile service, or an Internet service, and/or the type of directory assistance application (e.g., a television widget, a mobile application, a desktop application, etc.). In this way, the directory assistance operator may identify the type of user device, the capabilities of the user device, the type of enhanced services that may be available, etc. Unique string field 315 may indicate a unique string. According to an exemplary implementation, when network device 160 generates a context identifier, network device 160 may assign a time-to-live value to the context identifier. An exemplary scenario is described below in which the context identifier includes type of service field 310.
Referring back to FIG. 1C, user device 155 may receive the directory assistance operator request with the context identifier instead of directory assistance operator network 130. According to this embodiment, the directory assistance operator may begin providing directory assistance, before context information is received, based on the information included in the context identifier (e.g., type of service field 310). For example, the directory assistance operator may launch an application or communicate with a third party service provider to begin providing an enhanced service to the user.
According to other embodiments, context identifier 305 may include other types of informational fields. For example, context identifier 305 may include a type of services to which the user is subscribed field. For example, the user may be subscribed to television, mobile, and Internet services. The type of services to which the user is subscribed field may indicate the services to which the user is subscribed. Based on this information, the directory assistance operator may identify different enhanced services available to the user based on his/her subscriptions (e.g., without requesting this information from the user). According to such an implementation, network device 160 may communicate with a subscriber profile repository (e.g., resident in one or more of mobile network 105, television network 110, etc.) to identify the service(s) subscribed to by the user. Network device 160 may receive, for example, a device identifier (e.g., a network address (e.g., a media access control (MAC) address, an Internet Protocol (IP) address), an equipment identifier (e.g., an International Mobile Equipment Identity (IMEI), etc.)), a telephone number, etc., associated with user device 135, 140, 145, etc., to obtain subscription of service information from the subscriber profile repository.

Category field 395 may store a search category, such as a business category or person, or a more particular category (e.g., a yellow page category, such as automotive repair, etc.) inputted by the user via a directory assistance application.
As previously described, when context information is received by user device 155, the context information may be automatically populated in fields of one or more graphical user interfaces associated with a directory assistance operator application. FIG. 4A is a diagram illustrating an exemplary graphical user interface of a directory assistance operator application. As illustrated, the graphical user interface screen may include a user information section 405, a context information section 425, and an enhanced service section 455. According to other implementations, the graphical user interface screen may include additional, fewer, and/or different sections of fields than those described herein.
User information section 405 may include information pertaining to the user. As an example, user information section 405 may include a service provider field 410, a user device/service field 415, other service field 415, and a mobile telephone number field 420. Service provider field 410 indicates the service provider of the user (e.g., Verizon, etc.). User device/service field 415 indicates the type of device or service associated with a directory assistance operator communication. In this example, user device/service field 415 indicates that the user initiated a communication for directory assistance operator service via television FIOS. Other service field 415 indicates other services subscribed to the user (e.g., mobile service). Mobile telephone number field 420 indicates a mobile telephone number associated with the user.
Context information section 425 may include information pertaining to the context of the user or the context of the user and search(es) performed by the user for directory assistance. As an example, context information section 425 may include a location of user field 430, a location of search field 435, a search query field 440, a search category field 445, and a context identifier field 450. Location of user field 430 indicates a location of the user (e.g., Norfolk Va. 23501). Location of search field 435 indicates a location pertaining to a search conducted by the user (e.g., Norfolk Va. 23501 and the search radius (e.g., 25 miles)). Search query field 440 indicates a search query (e.g., a last search query or multiple search queries) initiated by the user via a directory assistance application, which in this example, may be a 411 widget associated with the user's television service device(s). Search category field 445 indicates a search category (e.g., business). Context identifier field 450 indicates the context identifier.
Enhanced service section 455 may permit a user (e.g., a directory assistance operator) to provide enhanced services to the user. For example, as illustrated in FIG. 4B, user device 155 may send an enhanced directory assistance request to the Internet or a third party service via directory assistance operator network 130. Depending on the enhanced service, the enhanced directory assistance request may include information pertaining to a listing (e.g., a business name, a business address, a telephone number, etc.). User device 155 may receive an enhanced directory assistance response, which may be provided to the user via an appropriate user device, as illustrated in FIG. 4C. For example, coupons would not be sent to the user via a television service user device (e.g., set top box and television) since the user will not be able to use or print the coupons. However, the directory assistance operator may provide the coupons to the user via user device 130 or user device 140.
According to other embodiments, the directory assistance operator may provide information to the user's service provider, a third party service, or the user's user device to permit these enhanced services to be provided, as described further below.
Referring back to FIG. 4A, as an example, enhanced service section 455 may include a television video ads field 460, a coupons field 465, a Web site Uniform Resource Locator (URL) field 470, a user reviews field 475, a BBB information field 480, an hours of operation field 485, a smartphone field 490, and a horoscope field 495.
Television video ads field 460 may permit the directory assistance operator to communicate a request to the user's service provider for television advertisements pertaining to the business requested by the user. For example, television network 110 may receive a request from user device 155/directory assistance operator network 130 that includes listing information pertaining to a business that provides vehicle repair. Television network 110 (e.g., a television content server) may conduct a search to determine whether there is a television advertisement for the vehicle repair shop indicated by the listing information. If one or more television advertisements are found, the 411 widget GUI displayed by user device 140 may prompt the user that a television advertisement(s) is available for viewing. The user may then select and play the television advertisement.
Coupons field 465 may permit the user to receive coupons. For example, according to an exemplary implementation, the directory assistance operator may access a web site that offers coupons via coupons field 465. The directory assistance operator may conduct a search for coupons based on listing information. If coupons are obtained, the directory assistance operator may provide these coupons to the user (e.g., via mobile network 105 or Internet 115).
Web site URL field 470 may permit the user to receive a Web site URL. For example, according to an exemplary implementation, the directory assistance operator may determine whether a business associated with the listing information has a Web site URL. If the business has a Web site URL, the directory assistance operator may provide the URL to the user.
User reviews field 475 may permit the user to receive user reviews pertaining to a listing (e.g., a business listing). BBB information field 480 may permit the user to receive BBB information pertaining to a listing (e.g., a business listing). Hours of operation field 485 may permit the user to receive the days and times a business is open, and horoscope field 495 may permit the user to receive his/her horoscope. Similar to that previously described, the directory assistance operator may obtain these types of information and provide them to the user.
Smartphone field 490 may permit the user to receive navigational assistance to a listing destination. For example, according to an exemplary implementation, the directory assistance operator may communicate a request to the user's service provider or a third party service to provide navigational assistance to the user. As an example, if the user receives listing information via user device 135, the user may be prompted as to whether the user would like navigational assistance to the location of the listing. Other types of enhanced service information may be provided, such as, show times (e.g., movie listings, Broadway show times, etc.).
According to an exemplary embodiment, context information pertaining to directory assistance may extend to multiple types of user devices based on a context identifier. The description below discloses exemplary scenarios that are further illustrative of a directory assistance service based on the context identifier.
According to an exemplary scenario, a directory assistance operator receives a request from a user for directory assistance. The directory assistance operator may identify a listing with which the user is satisfied. The directory assistance operator, via user device 155, may update context information, associated with the context identifier stored in context table 350, with listing information. The user, via user device 140 (e.g., a television) may select a refresh icon or a search again icon, via the 411 widget GUI, to receive the updated listing information. The user may request, via user device 140 and television network 110, to receive any available television advertisements pertaining to the listing.
According to another exemplary scenario, a user uses user device 135 (e.g., a smartphone) having a mobile 411 application to search for a listing. The user is not satisfied with the search results and initiates a communication to a directory assistance operator. The communication includes the context identifier. The user and the directory assistance operator converse. The directory assistance operator performs a search based on the context information obtained from network device 160. The directory assistance operator sends the listing to the smartphone in a communication, as illustrated in FIG. 5. Upon receipt of the communication (e.g., an SMS message, an MMS message, etc.), an application is awakened (e.g., the mobile 411 application, an electronic communication application, or some other application (e.g., a web browser, etc.)) on the smartphone to provide an enhanced service to the user. As an example, the application may send the context identifier to a third party server 505, which may retrieve (updated) context information from context table 350 associated with network device 160, and use the context information to provide the enhanced service.
According to another exemplary scenario, a user uses a user device 145 (e.g., a desktop computer) to search for a directory listing on a web site that provides directory listing information. The user finds the listing and sends the listing to network device 160. Based on the user's request, a context identifier is sent to another user device, such as user device 135 (e.g., a tablet device). The next day, the user turns on the tablet device and obtains the context identifier, via a communication (e.g., an email message, an SMS message, etc.) from network device 160. User device 135 obtains the context information from network device 160 based on the context identifier and permits the user to select one or more enhanced services (e.g., directions, coupons, advertisements, etc.).
According to another exemplary scenario, a user uses a user device (e.g., user device 135, user device 135 user device 145) to invoke the directory assistance operator service. In this example, the user does not attempt a search. Rather, the user selects, for example, a directory assistance operator icon to receive the directory assistance operator service. According to such a scenario, the context information sent to network device 160 may include, for example, the user's location, the user's search location (e.g., based on a user's preference) and the type of service. The context information may also include other types of information (e.g., other services to which the user is subscribed). As previously described, the user device receives a context identifier that is transmitted to directory assistance operator network 130 and context information may be obtained by the directory assistance operator.
FIGS. 6A and 6B are flow diagrams illustrating an exemplary process 600 associated with an exemplary embodiment of a directory assistance operator service based on a context identifier. According to an exemplary embodiment, the steps in process 600 are performed by network device 160. For example, processor 205 of network device 160 may execute application 215 (e.g., a context identifier application or program) and use other components (e.g., communication interface 220, etc.) to perform process 600.
Referring to FIG. 6A, in block 605, network device 160 receives context information pertaining to a directory assistance service. For example, network device 160 receives context information from a user device (e.g., user device 135, user device 140, user device 145) via communication interface 220. As previously described, the context information may include the location of the user, the location of the search, a business category, a search query, etc., depending on the particular circumstances surrounding the invocation of the directory assistance operator service.
In block 610, network device 160 generates a context identifier. For example, processor 205 executes application 215 to generate a unique string in response to receiving the context information. For example, application 215 may include a randomizer, a random number generator, or some other suitable generator for generating the unique string. According to an exemplary implementation, the unique string may be based on the context information in which one or more portions of the context information may be used as seed(s) to generate the unique string. According to other implementations, the unique string is generated without reference to the context information.
According to other embodiments, the context identifier includes one or more informational fields, in addition to a unique string. As an example, an informational field may indicate the type of service (e.g., mobile service, television service, etc.) the user is using to receive directory assistance operator service and/or other services to which the user is subscribed.
In block 615, network device 160 stores the context identifier and the context information. For example, processor 205 executes application 215 to store the context identifier and the context information in a database or a data structure (e.g., context table 350). In block 620, network device 160 transmits the context identifier to the user device (e.g., user device 135, user device 140, user device 145) via communication interface 220.
In block 625, network device 160 receives the context identifier from a directory assistance device via communication interface 220. For example, a network device in directory assistance operator network 130 (e.g., a gateway, a server, etc.) or user device 155 may send a request that includes the context identifier to network device 160.
Referring to FIG. 6B, in block 630, network device 160 retrieves the context information corresponding to the context identifier. For example, processor 205 executes application 215 to perform a lookup of context information based on the received context identifier. According to an exemplary implementation, the context identifier may serve as a key or a pointer to the context information stored in context table 350.
In block 635, network device 160 transmits the context information to the directory assistance device via communication interface 220. For example, network device 160 transmits the context information to the network device in directory assistance operator network 130 or user device 155.
Although FIGS. 6A and 6B illustrate an exemplary process 600 for providing a directory assistance operator service based on a context identifier, according to other embodiments, process 600 may include additional operations, fewer operations, and/or different operations than those illustrated in FIGS. 6A and 6B and described herein. Additionally, while process 600 is described with reference to an exemplary device (e.g., network device 160), according to other embodiments, block(s) described in process 600 may be performed by a device or combination of devices other than those specifically mentioned. For example, user device (e.g., user device 135, user device 145, etc.) may perform one or more blocks described in process 600.
Additionally, network device 160 may service requests for context information from devices other than directory assistance (operator) devices. For example, user devices (e.g., user device 135, user device 140, user device 145) may request context information from network device 160 based on the context identifier. As an example, when context information is updated, the user device may obtain the context information from network device 160. Additionally, a third party device or a service provider device (e.g., the user's service provider) may obtain context information from network device 160, based on the context identifier, to provide the user with enhanced services.
FIG. 7 is a flow diagram illustrating an exemplary process 700 associated with an exemplary embodiment of a directory assistance service based on a context identifier. According to an exemplary embodiment, the steps in process 700 are performed by user device 135, user device 140, or user device 145 (referred to as user device). For example, processor 205 of the user device may execute application 215 (e.g., a 411 widget application or program, a 411 mobile application, or a 411 Internet application) and user other components (e.g., communication interface 220, etc.) to perform process 700.
In block 705, the user device aggregates context information pertaining to a directory assistance service. For example, processor 205 executes application 215 to obtain context information from various sources, such as one or more files created and stored during runtime of the directory assistance application (e.g., based on the name of the file(s), format of information included in the file(s), etc.), user preference information, information included in the directory assistance response (e.g., identify a field(s) in a packet or other information container, which may include a search query term(s), a search result, or other parameters pertaining to the search (e.g., area of search, radius of search, etc., as illustrated in step (4) of FIG. 1B), user location information (e.g., GPS information). According to an exemplary embodiment, the user device aggregates the context information when the user device receives a user input (e.g., via a graphical user interface) to invoke a directory assistance operator service.
In block 710, the user device transmits the context information to network device 160 via communication interface 220. For example, processor 205 executes application 215 to generate a directory assistance request that includes the context information.
In block 715, the user device receives a context identifier from network device 160 via communication interface 220. For example, the user device receives a directory assistance response that includes the context identifier via communication interface 220.
