     DETAILED DESCRIPTION 
     A system and method are provided that allow mobile devices to securely communicate over wireless network with one or more security system control panels for controlling the security systems remotely.  FIG. 1  is a high-level architectural diagram that illustrates the system of the present disclosure in one embodiment. A mobile device  102  may include an application or software that presents a virtual security keypad to the user on the mobile device for entering data or receiving data as if the user were directly using a security system control panel at a premise being secured  104 . Thus, a virtual security keypad emulates a security control panel keypad, for example, on a mobile device. 
     The system and method of the present disclosure in one embodiment leverages Hypertext Transfer Protocol (HTTP) or HTTPS (Hypertext Transfer Protocol over Secure Socket Layer) protocol and Java™ virtual machine (VM) built in phones, personal digital assistants (PDAs) or Blackberries™ or like mobile devices (MD). In one embodiment, HTTP and HTTPS are data transport layers and Java™ VM provides the convenient way to render data on the mobile devices. Mobile devices may install Java™ application (also referred to as Midlet). The Java™ application provides or renders the virtual security keypad on the mobile devices. A Midlet issues HTTP/HTTPS requests to Network Operating Center (NOC) such as Honeywell&#39;s Alarmnet Data Server ( 106 ). 
     Communication protocol may be implemented for communicating between the mobile device&#39;s application program that provides the virtual security keypad and a network operating center ( 106 ) that provides communication connections to and from the security control panel ( 108 ). An example of a network operating center ( 106 ) is Honeywell&#39;s Alarmnet Data Server. In one embodiment of the present disclosure, the following types of requests or protocols are utilized: Session_Init, Session_Poll, Session_KeyCodes, Session_End. Session_Init request prepares NOC for incoming session to security panel. This request, for example, contains security panel identification and globally unique session identification. NOC establishes virtual connection with the security panel, for example, similarly to a Total Connect session. Session_Poll requests the security panel status. Session_KeyCodes request carries the end-user (MD&#39;s user) keystrokes that perform actions on a security panel. Examples of actions may include but are not limited to ARM or DISARM. Briefly, ARM command refers to arming or turning on a security system. Similarly, DISARM command refers to disarming or turning off the security system. Session_End request requests to end the communication session with a security panel. Other command may be issued using the virtual security keypad. 
     As described above, MD ( 102 ) can operate in HTTP or HTTPS mode. However, HTTPS requires substantial MD resources effectively causing sluggish responses. The system and method of the present disclosure in one embodiment can operate in HTTP secure mode. In this mode HTTP requests contain URL parameters that describe one or more session requests described above for establishing a session and communicating between the virtual keypad of the Midlets ( 102 ) and the security system. In one embodiment, those URL parameters are encrypted, for example, using AES encryption standard, and may be encoded, for example, by converting binary into hex string and passed, for instance, within HTTP header. Any other encryption methodology may be used in the system and method of the present disclosure. By using Midlet or like JAVA™ based applications that can enable virtual security keypad on mobile devices, the end-user extends the access to his/her home or business security panel. 
     A premise being secured ( 104 ) includes a security control panel ( 108 ) for controlling the security system installed at the premise ( 104 ) and an Internet communicator ( 110 ) that enables the security control panel ( 108 ) to communicate over the Internet. MDs ( 102 ), NOC ( 106 ) and security panel ( 108 ) for example via an Internet communicator ( 110 ) may communicate over the Internet, for example, via an Internet service provider ( 112 ). 
       FIG. 2  illustrates a method and protocol details of establishing virtual connection from a security panel via mobile phone, PDA, etc., in one embodiment of the present disclosure. Mobile device  210  represents any type of mobile devices capable of running Java™ applications or like, and communicating wirelessly. Such devices may include but are not limited to portable electronic devices, cellular phones, personal digital assistants, smart phones, and laptops. NOC ( 212 ) generally represents a server that services communications between the mobile devices ( 210 ) and security control systems located at the premises being secured. 7845i-GSM ( 214 ) generally refers to a device that delivers Internet and/or digital communications via a wireless network such as the GSM (Global System for Mobile) network. 7845i-GSM is an example such devices. Any other devices capable of providing digital communications in a mobile network may be utilized in the system and method of the present disclosure. Security panel ( 216 ) generally refers to a security system control panel that is located at a premise being secured and may include user interface such as a screen monitor and a keypad. An example of a security panel is Vista  20 . 
     At step  1  ( 202 ), when Java™ Midlet application is activated on a mobile device ( 210 ) such as phone or PDA, it sends HTTP Session_Init request to Network Operating Center (NOC) ( 212 ). HTTP Session_Init request may be embodied as HTTP GET request and contains encrypted security panel identification, for example, 7845i-GSM radio identification, which routes data packets between virtual keypad and security panel. There may be other pieces of information such as session identification associated with Session_Init embedded into the request. Upon receiving the request NOC ( 212 ) establishes TCP binary connection with security panel ( 216 ) via 7845i-GSM Internet communicator ( 214 ), for instance, similarly as is done in the Total Connect services. 
     At step  2  ( 204 ), once NOC ( 212 ) establishes connection with security panel ( 216 ), the panel ( 216 ) sends encrypted status information back to NOC ( 212 ) via 7845i-GSM Internet communicator ( 214 ). It is a low-level security data and it is encrypted using AES (Advanced Encryption Standard). Any other encryption scheme may be utilized. Meanwhile, Midlet application on Mobile Device (MB) ( 210 ) sends its Session_Poll HTTP request. Upon receiving the Session_Poll request NOC ( 212 ) looks up the session identification and attaches the encrypted data from the security panel as the HTTP response to the Session_Poll request. 
     At step  3  ( 206 ), when end-user keys a command on Midlet (virtual security keypad) on the mobile device ( 210 ), the end-user keys the sequence of numbers or special symbols (such as “*” or “#”). The ASCII key values are captured by Midlet application, encrypted using AES (Advanced Encryption Standard) and may be encoded, for example, by converting binary into hex strings. They can be embedded into HTTP string character request. Any other encryption may be utilized. This request is labeled as Session_KeyCodes. Once HTTP request is formed by Midlet application, it is then sent from the mobile device ( 210 ) running the Midlet application to NOC ( 212 ) for processing. When a HTTP Session_KeyCodes request is received at NOC ( 212 ) it is unpacked, for example, to get binary content, decrypted, and then formatted, encrypted and sent to security panel ( 216 ) via 7845-iGSM Internet communicator ( 214 ). When a security panel ( 216 ) receives a message, it responds to it as it would to real security keypad. Data from panel forms the HTTP response with binary data content. The HTTP response is then sent to the mobile device ( 210 ) via 7845-iGSM Internet communicator ( 214 ) and NOC ( 212 ). 
     At step  4  ( 208 ), when the end-user wishes to end the virtual session, Midlet application on the mobile device ( 210 ) sends Session_End HTTP request to NOC ( 212 ) which in turn breaks the TCP binary connection with Internet communicator (7845i-GSM) ( 214 ) and security panel ( 216 ). 
     Various aspects of the present disclosure may be embodied as a program, software, or computer instructions embodied in a computer or machine usable or readable medium, which causes the computer or machine to perform the steps of the method when executed on the computer, processor, and/or machine.
