## Background
BACKGROUND OF THE INVENTION
Presence is generally defined as knowing that a person is available via, for example, a certain device over a particular medium as soon as a user connects to the network. For instance, via presence information, it may be ascertained that the person is available online, and on a connected device with a certain device profile. The user which indicates its presence on the network is termed a presentity. Presence is used to notify a group of watchers in a contact list about the state of person, including availability. When the user changes its presence state, each contact on the contact list is informed about the new presence state of the user. Presence infrastructure is used predominantly with Instant Messaging (IM) or Short Message Service (SMS) on a computer. However, the distinction between computers, personal digital assistants and cellular telephones has been progressively blurring which allows a cross over of functionality between one type of Internet Protocol (IP) device to another.
Radio jamming techniques are sometimes used either to block the use of cellular telephones in certain areas, or to notify a cellular telephone that it is in a restricted area and certain types of communication are not recommended or allowed. Cellular telephone jamming can be a legitimate tool for certain applications. For example, jamming can be used to prevent cellular telephone calls from interrupting a church service or a theater presentation through either blocking or ring restriction. The problem is, even when jamming is used for legitimate purposes, it can still have negative side effects. For example, jamming can prevent reception of emergency cellular telephone calls.
The present invention addresses negative side effects that can result from legitimate jamming such as a caller not knowing the person being called is in the restricted area such as in a theater. Current jamming devices may cause a cellular telephone to switch from ringer to vibrate mode. If the person in the theater receives an incoming cellular telephone call, that person may choose to answer the cellular telephone, but answering the cellular telephone may take time as the person leaves the theater and walks to the lobby. If the caller is unaware that the person is in the restricted area, the caller may hang up before the person receiving the call can answer. Presence can be used to communicate to a potential caller (the watcher) that the person receiving the call (the presentity) is in the restricted area.
Therefore, what is needed is a method of extending the presence system to cellular telephones to overcome negative side effects associated with jamming. More specifically, the present invention provides alternative communications during jamming in a presence system.
SUMMARY OF THE INVENTION
Presence is a technology in which information about one person, place, or thing is communicated to another person, place, or thing. In presence terminology, a person, place, or thing about which information is being collected is called a presentity, and a person, place, or thing receiving presence information is called a watcher. Currently, presence is widely used in Instant Messaging (IM) systems and is used to communicate to one IM user (the watcher) that another IM user (the presentity) is online and available for communication.
The present invention relates to using presence technology to inform a caller that the cellular telephone he or she is calling is being jammed. Cellular telephone jamming can be a legitimate tool for certain applications. However, even when jamming is used for legitimate applications it can still have negative effects. Some of the negative effects include a caller to a jammed cellular telephone does not know the telephone is being jammed and another is to prevent reception of emergency telephone calls.
The present invention addresses negative side effects that can happen as a result of legitimate jamming. That is that a caller does not know a person being called is in a restricted area. For example, in a theater, a sophisticated jamming device may cause a cellular telephone to switch from ringer to vibrate mode. If a person in the theater receives an incoming telephone call, that person may choose to answer the telephone, but answering the telephone may take some time. The person may have to leave the theater and walk to the lobby. If the caller does not know what's going on, the caller may hang up before the person receiving the call can answer. The jamming device can provide extra information to a cellular telephone or a cellular network. For example, in a theater, a jamming device may tell a cellular telephone, the location of the theater and when the show will be over. In another example, a jamming device may tell a cellular telephone that the person being jammed is in a class, in surgery or in a meeting. The jamming device may give the name of a person to contact, like a theater usher, in the case of an emergency. All this information and other information of this type can be included in data sent by the jamming device.
Presence can be used to communicate to a potential caller (the watcher) that the person receiving the call (the presentity) is in a restricted location. This presence information can be available to the watcher before the watcher initiates the telephone call. The presence information communicated to the watcher may contain a list of alternative ways to contact the presentity. In one embodiment of the invention the presence information may inform the watcher that the presentity is unavailable by direct telephone call but is available by voice mail, Instant Messaging (IM), or e-mail. The presence information may also contain a list of the presentity's preferences. For example, the presence information may say that while the presentity is in a restricted area, the presentity prefers to be contacted by e-mail.
An individual may also have a personal jamming device in his or her home. The jamming device may tell the cellular telephones in the user's home that the person is asleep or doing something important.
The presence system can combine information from a jamming device with information from other sources to produce an inferred state information. This is information about the presentity calculated from data collected by the presence system. For example, information from the jamming device can be combined with information from a person's calendar to produce an inferred estimate of when the presentity will be available in the future.
In one embodiment of the present invention, a method for to provide alternative communications during jamming in a presence system, that comprises, registering a mobile device as a presentity to a presence server in the presence system, detecting a communication jamming of the mobile device, providing information related to the detected communication jamming as a state information to the presence server, and upon attempting to communicate with the mobile device while being jammed, providing the state information and offering an alternative communication suggestion. The method may also provide a presentity contact preference, wherein the alternative communication suggestion is voice mail, instant messaging or e-mail. The method may also determine a security authorization of at least one of a caller, and a service attempting to communicate with the mobile device. The method may provide a presentity physical location, direct to an alternative contact, and upon attempting to communicate with the mobile device, providing at least one of a caller, and a device attempting to communicate with the mobile device, with an alternative contact information. The method may combine the information related to the detected communication jamming with a presentity schedule to produce a presentity inferred state and provide the information related to the detected communication jamming prior to attempting the communication.
In another embodiment of the present invention, a computer readable medium comprises instructions for registering a mobile device as a presentity to a presence server, detecting a communication jamming of the mobile device, and providing the information related to the detected communication jamming as a state information to the presence server. The computer readable medium may comprise instructions to supply selective communications jamming within a user's home wherein the selective jamming is timed and wherein the selective jamming excludes a pre-determined set of callers. The computer readable medium may determine a security authorization of at least one of a caller, and a device attempting to communicate with the mobile device and combine the information related to the detected communication jamming with a presentity schedule to produce a presentity inferred state.
In yet a further embodiment, a system adapted to provide alternative communications during jamming in a presence system, that comprises, a mobile device registered as a presentity on the presence system, and a presence server on the presence system, the presence server adapted to detect communication jamming of the mobile device, and provide the information related to the detected communication jamming as a state information to the presence server. Whereupon attempting to contact the mobile device while being jammed, at least one of a caller, and a device attempting to communicate with the mobile device, is provided with the state information and offered an alternative communication suggestion. The system may combine the information related to the detected communication jamming with a presentity schedule to produce a presentity inferred state.
