Description:
BACKGROUND  
       [0001]     Mobile or wireless terminals, such as cell phones, mobile phones, and similar wireless devices are no longer the hallmark of traveling business executives and other professionals, but have become essential personal items that are always carried by many people all over the world on their persons.  
         [0002]     Modern cell phones are equipped with a feature know as enhanced home network. This feature allows cell phone users to operate their phone throughout North America or the European Community commonly without incurring roaming charges. Because the cell phones are, therefore, operational at no additional prohibitive cost across borders between states or countries, there is no reason to leave them behind while traveling. In a sense, the cell phone goes where its owner goes, and this, unfortunately, includes environments in which the use of a cell phone is undesirable, dangerous, or even illegal.  
         [0003]     In entertainment places, such a theaters, opera houses, symphony and music halls, ringing of cell phones is not only disruptive, but it may also interfere with aesthetic or other aspects of the performance. In government buildings and courthouses, security reasons may place additional restrictions on the use or even admittance of cell phones. In airplanes, explosives handling sites, hospitals, and other places in which radio-operated equipment may be used, the operation of cell phones may lead to spurious radio transmissions that may cause interference, malfunction, and may even trigger catastrophic events.  
         [0004]     Currently, X-Ray machines and scanners are used to discover and confiscate cell phones at the entrance to courthouses and other places in which these devices are prohibited. Spotting miniature cell phones through X-Ray machines is not only difficult but it is also time consuming.  
         [0005]     Another solution being used is a jamming device for mobile phone signals that disrupts the reception of the signal at the mobile phone, making it impossible to receive service from the mobile network. A permit is usually required in order to operate this device and it is currently illegal to use such a device in the United States. When this device is used, functions such as Short Messaging Service (SMS), email, and Internet access are all disabled.

         [0017]     Turning now to  FIG. 2 , a diagrammatic view of exemplary embodiments of the detection device  20  in an operation environment is shown. The detection device  20  may be programmed to transmit a control signal to wireless terminals  34  within a restricted area  32 . According to an exemplary embodiment, the control signal includes a preferred operational mode for the wireless terminal  34  inside of the restricted area  32 . The restricted area  32  is defined as an area in which the unrestricted use of the wireless terminals  34  is undesirable or prohibited. In exemplary embodiments, the restricted area  32  may be a stationary structure or facility including but not limited to, a government building, a courthouse, a hospital, a restaurant, or a theater. In other exemplary embodiments, the restricted area  32  may be a mobile facility such as an airplane or a boat.  
         [0018]     The preferred operational mode may include an availability of a feature of the wireless terminal  34  and a setting of the wireless terminal  34 .

For example, if the restricted area  32  is a church, movie theater, or some other place that an individual visits on a regular basis, the processor  26  may keep track of the preferred operational mode of the user&#39;s wireless terminal  34 . In exemplary embodiments, the user may be prompted to have the detection device  20  store the preferred operation mode of their wireless device  34  and automatically switch the operational mode of the wireless terminal  34  when it is present in the restricted area.  
         [0020]     Turning now to  FIG. 3 a  flowchart of the operation of exemplary embodiments of the detection device  20  is illustrated generally as  50 . As shown in process block  52 , when inside of the restricted area  32  the wireless terminal  34  detects a control signal emitted by the detection device  20 . After detecting the control signal, the wireless terminal  34  receives the preferred operational mode for the wireless terminal  34 , as depicted in process block  54 . Upon receiving the preferred operation mode for the wireless terminal  34 , the wireless terminal  34  presents the user with an option for changing the operational mode of the wireless terminal  34  to the preferred operational mode, as shown in process block  56 .  
         [0021]     Continuing with  FIG. 3 , as depicted at process block  58  the wireless terminal  34  receives a command from the user indicative of a desired operational mode of the wireless terminal  34 . If the user indicates that the operational mode of the wireless terminal  34  should be changed to the preferred operational mode the process proceeds to process block  60 . Otherwise, the operational mode of the wireless terminal  34  remains unchanged, as shown at process block  62 . If the user adapts the preferred operational mode for the wireless terminal  34 , the wireless terminal may store a previous operational mode of the wireless device, as shown at process block  60 . Additionally, the wireless terminal  34  may restore the operational mode of the wireless terminal to the previous operational mode when the control signal is no longer detected, as shown at process block  64 . The restoration of the previous operational mode may occur automatically once the wireless terminal  34  no longer detects the presence of the control signal or responsive to a user command to restore the previous operational mode.  
         [0022]     In additional exemplary embodiments, the detection device  20  may be used to broadcast a message to wireless terminals  34  within the restricted area  34 . For example, the control signal may include a command that instructs the wireless terminals  34  to present a message on a display of the wireless terminal  34 .
