Definitions

  • the present invention generally relates to wireless communication systems and more specifically to a method and system for providing supervisory control over wireless phone data usage.
  • Wireless phones are widely used in this country.
  • Wireless phone service providers typically allow a wireless phone subscriber to place calls send and receive text or multimedia messages, browse the Internet, etc. at any time.
  • more and more parents are inclined to have their children of school age carry wireless phones to make it easier for their children to contact them and vice versa.
  • Wireless data usage includes, without limitation, text messaging, chat, multimedia messaging, Internet browsing, file downloading and uploading, audio, video or other media streaming and other packet data transfers.
  • the disclosed system allows a Supervisor, such as a parent or manager, to establish individual profiles for supervised Users of respective wireless phones across a range of parameters. For example, a parent can establish a user profile for each child that is to be provided a wireless phone. The user profile allows the use of the phone by the child, subject to controls over data usage, as specified by the Supervisor.
  • the disclosed system allows the Supervisor to limit the number of text messages sent and/or received during a specified control period, such as a week or a month, to a predetermined maximum number of messages and/or kilobytes and to prevent incoming and/or outgoing messages during specified periods, such as during school hours, except from and/or to predetermined numbers or addresses (collectively "always- accessible addresses" or "always-accessible identifiers") specified by the Supervisor.
  • the Supervisor may be the subscriber who ordered and pays for the wireless service, as may be the situation in the case of a parent supervisor.
  • the Supervisor can also be the user of the phone, as in the case of a self-supervised user.
  • the Supervisor may be a person, such as a manager in a corporation, who oversees wireless phone usage by employees, but who is not the subscriber of record, from the perspective of the wireless carrier.
  • the actual subscriber can be the Supervisor, the user of the wireless phone, a corporation or a third party.
  • the Supervisor is associated with the supervised wireless phone, as described below.
  • Restrictions can also be defined with regard to data usage while the phone is at or near defined geographic locations. Separate restrictions can be applied to each type of data service. For example, text messages can be blocked and Internet browsing can be allowed while the phone is within the grounds of a school attended by the user. Additionally, a location restriction can be employed in conjunction with other restrictions on data usage and capabilities described herein.
  • streaming video can be restricted if the wireless phone is within a prescribed geographic region and the time is within a time period specified by the Supervisor. More specifically, the decision whether to block or permit a data usage can be made as a Boolean function of any of the applicable restrictive or permissive criteria applicable to phone or data usage herein described.
  • the location of the wireless phone can be obtained using cell sector identifiers alone or in combination with signal strength information, a global positioning system receiver disposed within the wireless phone or by any other suitable techniques (alone or in combination) for determining the geographic location of the wireless phone.
  • messages to or from predetermined numbers or addresses specified by the Supervisor, and time spent browsing Internet sites specified by the Supervisor are not counted toward the total number of messages or minutes permitted during the specified control period.
  • a supervised user attempts to use a data service during a period in which such use is prohibited, or from a prohibited geographic region, a message can be played or displayed to the user indicating that the attempt will not be honored at that time and/or from that location.
  • a message can be sent to a supervised user during a period during which data usage is prohibited or while the wireless device is within a prohibited geographic region, a message can be sent to the originating party indicating that the phone is not accessible at the present time or in the current location.
  • the Supervisor can also specify telephone numbers, addresses, uniform resource locations (URLs) or identifies of other sources within the user profile that are never permitted to send data to the supervised user's phone, and the system prevents any data from such sources from being delivered to the wireless phone.
  • URLs uniform resource locations
  • the system can prevent the wireless phone from being used to send data to addresses or other destinations specified by the Supervisor.
  • the data destinations that cannot be reached from the supervised phone and the data source from which data transmissions are blocked are referred to herein as "never- accessible addresses" (or “never-accessible identifiers").
  • data such as text messages announcing new voicemail messages from callers, other than from always-accessible callers, can optionally be blocked.
  • Certain data sources, namely the always-accessible addresses can be identified within the user profile and data from these numbers can always access the supervised wireless phone (or voicemail, should the phone not be answered), even during a prohibited use period or in a prohibited use location.
  • a parent's home number, wireless phone number, work or personal e-mail address can be included in the profile, so that the parent is always able to reach the child's phone.
  • Incoming data for a supervised phone is analyzed to determine if the source of the data is one of the always-accessible addresses. If the data source is not on the always-accessible list, the data can be discarded or, alternatively, stored until the mobile phone is no longer prohibited from receiving the data.
  • a data source is provided an ability to send data to the supervised wireless phone upon entering a security code, referred to herein as a "cut-through code.”
  • the Supervisor (or an individual having knowledge of the cut- through code) can access the supervised wireless phone when sending data from a number other than one of the always-accessible numbers via the use of the cut-through code.
  • the user profiles are maintained within a database that can be modified at any time by the Supervisor. More specifically, the Supervisor can log in over a wide area communications network (such as the Internet) or an other network or combination of networks that permits remote access.
  • the Supervisor can then change usage limits in real time, change, add, delete addresses that are always or never accessible to/by a particular supervised wireless phone, change restricted use times and make all other permitted changes to the respective user profiles.
  • a security code is required to be entered and is verified before permitting changes to be made to the managed user profiles under the Supervisor's controls.
  • the presently described supervisory functions can operate independent of billing controls, such as real-time pre-paid billing controls or post-paid billing systems, that can also be applicable to the supervised phone.
  • the information defining the restrictions on phone use can be stored in a separate database or in a common database i.e., a database that also stores billing parameters.
  • the presently described functionality can be provided as an overlay to pre-paid billing controls or other call billing and control systems and can be configured to share resources with such other systems while exercising call control independently of such other systems.
  • the presently described supervisory system can employ one or more servers that operate independent of servers that provide billing functionality, or alternatively, the presently described supervisory system can share server resources while exercising control independent of restrictions pertaining to billing functions.
  • the user profiles allow use of wireless phones by children or other supervised users, subject to controls on incoming and/or outgoing data usage specified by the Supervisor.
  • Other aspects, features and advantages of the presently disclosed system for exercising supervisory control over wireless phone usage will be apparent from the Detailed Description of the Invention that follows.

Abstract

Un système pour surveiller l'utilisation des radiotéléphones permet à un surveillant d'établir pour des utilisateurs de radiotéléphones surveillés des profils d'utilisateurs portant sur des batteries de paramètres et qui sont enregistrés dans une base de données de profils d'utilisateurs. De tels paramètres peuvent comporter un ou plusieurs emplacements où l'utilisation du radiotéléphone est limitée ou permise. En outre, on peut apporter des limitations d'utilisation du radiotéléphone portant notamment sur le temps total d'utilisation, le nombre de messages ou d'octets, et ce, en s'appuyant sur l'utilisation totale du téléphone pendant des périodes de gestion spécifiques, des périodes chronologiques, des dates ou des jours de la semaine pendant lesquels l'utilisation du téléphone est limitée ou permise. Il est possible d'établir une ou plusieurs listes incluant des numéros ou d'autres identifiants qui sont toujours accessibles, et une ou plusieurs listes incluant des numéros ou d'autres identifiants qui ne sont jamais accessibles. Au cas où une communication, un message ou une navigation ne respecte par des critères définis, la tentative de communication est bloquée. Des messages définis peuvent être restitués ou affichés à l'interlocuteur appelé ou appelant, suivant le cas, lorsqu'une tentative de communication est bloquée. Il est possible de spécifier des combinaisons booléennes de restrictions et de critères d'utilisation autorisé pour le radiotéléphone, de façon à disposer d'une certaine souplesse lors de l'établissement des critères d'utilisation du radiotéléphone.
