The memory 116 is communicatively coupled to the I/O subsystem 114 via a number of signal paths. Although only a single memory device 116 is illustrated in FIG. 1, the portable communication device 102 may include additional memory devices in other embodiments. Various data and software may be stored in the memory 116. For example, one or more operating systems, applications, programs, libraries, and drivers that make up the software stack executed by the processor 110 may reside in memory 116 during execution.

The data storage 118 may be embodied as any type of device or devices configured for the short-term or long-term storage of data. For example, the data storage 118 may include any one or more memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices

The communication circuitry 120 of the portable communication device 102 may include any number of devices and circuitry for enabling communications between the portable communication device 102 and one or more devices or networks as discussed in more detail below. The communication circuitry 120 may be configured to use any one or more, or combination thereof, communication protocols to communicate, such as, for example, a cellular communication protocol Wideband Code Division Multiple Access (W-CDMA)), a wireless network communication protocol (e.g., Wi-Fi®, WiMAX), a wireless personal area network communication protocol (e.g., Bluetooth®), a wired network communication protocol (e.g., TCP/IP), and/or other communication protocols.

The portable communication device 104 may be substantially similar to the portable communication device 102 and include similar components, which have been identified in FIG. 1 with a common reference numbering scheme, including a processor 150, a processor core 152, a 110 subsystem 154, a memory 156, a data storage 158, a communication circuitry 160 and one or more peripheral devices 162. As such, the description provided above of the components of the portable communication device 102 is equally applicable to those similar components of the portable communication device 104 and is not repeated herein so as not to obscure the present disclosure. Of course, it should be appreciated that in some embodiments the portable communication devices 102, 104 of the system 100 may be dissimilar to each other. For example, the portable communication devices of the system 100 may be embodied as various types of communication devices different from each other (e.g., a tablet, a smart phone, or other communication device) and include components typically found in such corresponding communication devices.

Each of the portable communication devices 102, 104 of the system 100 may be embodied as any type of communication device capable of performing the functions described herein. For example, each of the portable communication devices 102, 104 may be embodied as, without limitation, a smart phone, a cellular telephone, a handset, a messaging device, a tablet, a consumer electronic device, and/or any other portable communication device configured to recovering the operating system.

FIG. 2 illustrates an embodiment of an environment 200 for recovering the operating system, which is established by the system of FIG. 1. In an embodiment, the environment 200 may comprise a recovery agent 205 residing in a firmware 203 of the portable communication device 102, which may communicate with a recovery agent 215 residing in an operating system 212 of the portable communication device 104, to recover an operating system 202 in the portable communication device 102, in response that a system detection module 204 residing in the firmware 203 detects that the operating system 202 is crashed.

In an embodiment, the system detection module 204 may detect a system of the portable communication device 102 during a system boot process, including detecting whether the operating system 202 is crashed, e.g., because of a malicious attack to the portable communication device 102. If the operating system 202 is crashed, the system detection module 204 may send a recovery request to the recovery agent 205. However, it should be understood that other embodiments may implement other technologies for the recovery request. For example, the system detection module 204 may report to a user of the portable communication device 102, who may request the recovery, e.g., through pressing a key.

In an embodiment, the recovery agent 205 may comprise a near field communication (NFC) module 206 a high speed wireless communication module 207, a recovery manager 208 and a read/write module 209. The recovery agent 215 may comprise a near field communication (NFC) module 216, a high speed wireless communication module 217, a recovery manager 218 and a read/write module 219.

In an embodiment, the NFC module 206 may detect whether the portable communication device 104 exists, connect the portable communication device 102 with the portable communication device 104 and obtain a network address of the portable communication device 104, based on NFC technologies. In response to detecting the existence of the portable communication device 104, the recovery manager 208 may initiate a session with the recovery manager 218. For example, the recovery manager 208 may coordinate the NFC module 206 to send a request of connection and receive a response to the request from/to the recovery manager 218 of the portable communication device 104.

In an embodiment, after the session is initiated, the NFC module 206 may disconnect the NFC connection with the portable communication device 104. The high speed wireless communication module 207 may then connect the portable communication device 102 with the portable communication device 104, based on a high speed wireless communication technology, such as Bluetooth or WiFi. The high speed wireless communication module 207 may complete the connection using the network address obtained from the NFC module.

Through the high speed wireless connection, the recovery manager 208 may continue the session with the recovery manager 218 to copy an operating, system image from the portable communication device 104 using the read/write module 209. Examples of the operating system image may include the operating system 212 of the portable communication device 104, except for any data or codes desired to keep secret from the portable communication device 102, such as private data. In another embodiment, the operating system image may be obtained from a third party, e.g., an online source, and pre-stored in the portable communication device 104. In yet another embodiment, the operating system image may be copied from the portable communication device 102 before the operating system 202 is crashed.

In an embodiment, the NFC module 216 may detect whether the portable communication device 102 exists, connect the portable communication device 104 with the portable communication device 102, and obtain a network address of the portable communication device 102, based on the NFC technology. In response to detecting the existence of the portable communication device 102, the recovery manager 218 may initiate a session with the recovery manager 208 of the portable communication device 102. For example, the recovery manager 218 may coordinate the NFC module 216 to receive a request of connection and send a response to the request from/to the recovery manager 208 of the portable communication device 104.

In an embodiment, after the session is initiated, the NFC module 216 may disconnect the NFC link with the portable communication device 102. The high speed wireless communication module 217 may then connect the portable communication device 104 with the portable communication device 102, based on a high speed wireless communication technology, such as Bluetooth or WiFi. The high speed wireless communication module 217 may complete the connection using the network address obtained by the NFC module.

Through the high speed wireless connection, the recovery manager 218 may continue the session with the recovery manager 208 to obtain the operating system image using the read/write module 219 and send the operating system image to the portable communication device 102.

As illustrated in FIG. 2, the portable communication device 102 may further install various applications running over the operating system 202. Similarly, the portable communication device 104 may further install a firmware 213 running under the operating system 212 and various applications 211 running over the operating system 212.

In some embodiments, the various modules of the environment 200 may be embodied as hardware, software, firmware or a combination thereof. For example, any of the above-stated modules may be embodied as software/firmware instructions stored in a machine-readable medium of the portable communication device 102 or the portable communication device 104.

With the above solution, the portable communication device 102 may recover the operating system from another portable communication device without the need of a wired connection, such as a data line or a USB. On the contrary, a wireless connection can be used to recover the operating system from a reliable source, namely, the portable communication device 104, which the user of the portable communication device 102 trusts and runs the operating system that may be suitable for the portable communication device 102 as well. In addition, since the portable communication devices 102 and 104 obtain each other's network address and initiate the session via the NFC connection, it avoids broadcasting under other wireless communication schemes to obtain the targeted network addresses, and thus enhances security for the later operating system image transmission.

FIG. 3 illustrates an embodiment of a method of recovering the operating system. The method on the left is implemented by the portable communication device 102, while the method on the right is implemented by the portable communication device 104.

Referring to the method on the left, in block 301, when booting the system of the portable communication device 102, the system detection module 204 may check hardware and software of the system. If, in block 302, the system detection module 204 detects that the operating system 202 is crashed before being loaded into a memory of the portable communication device 102, then in blocks 303-304, the portable communication device 102 may display the information about the operating system being crashed on its screen and detect whether the user presses a key to request the operating system recovery. If the user presses the key, then in block 305, the NFC module 206 or other device may detect whether the portable communication device 104 having a good operating system image suitable for the portable communication device 102 exists within a NFC communication distance. In response to detecting the existence of the portable communication device 104, the recovery manager 208 or other device may initiate a session with the recovery manager 218 or other device, in block 306. For example, the recovery manager 208 may coordinate the NFC module 206 to connect with the portable communication device 104 and obtain the network address of the portable communication device 104, based on the NFC technologies. In an embodiment, after the session is initiated, the NFC module 206 may disconnect the NFC connection with the portable communication device 104.

Then, in block 307, the recovery manager 208 or other device may coordinate the high speed wireless communication module 207 or other device to connect the portable communication device 102 with the portable communication device 104, based on a high speed wireless communication technology, such as Bluetooth or WiFi. The high speed wireless communication module 207 may complete the connection using the network address obtained from the NFC module. In block 308, the recovery manager 208 or other device may continue the session with the recovery manager 218 and send a request of copying the operating system image to the portable communication device 104. Examples of the operating system image may include the operating system 212 of the portable communication device 104, except for any data or codes desired to keep secret from the portable communication device 102, e.g., private data. In an embodiment, the operating system image may be obtained from a third party, e.g., an online source, and pre-stored in the portable communication device 104. In yet another embodiment, the operating system image may be copied from the portable communication device 102 before the operating system 202 is crashed.

In blocks 309-310, the recovery manager 208 or other device may receive the operating system image from the portable communication device 104, and install the operating system image onto the firmware 203 using the read/write module 209 or other device. In block 311, the portable communication device 102 may reboot and load the operating system image to the memory.

Referring now to the method on the right, in block 320, the NFC module 216 or other device may detect whether the portable communication device 102 exists within a NFC communication distance. In response to detecting the existence of the portable communication device 102, the recovery manager 218 or other device may initiate a session with the recovery manager 208 or other device, in block 321. For example, the recovery manager 208 may coordinate the NFC module 206 to connect with the portable communication device 102 and obtain the network address of the portable communication device 102, based on the NFC technologies. In an embodiment, after the session is initiated, the NFC module 216 may disconnect the NFC connection with the portable communication device 102.

Then, in block 322, the high speed wireless communication module 217 or other device may connect the portable communication device 104 with the portable communication device 102, based on a high speed wireless communication technology, such as Bluetooth or WiFi. The high speed wireless communication module 217 may complete the connection using the network address obtained from the NFC module 216. In block 323, the recovery manager 18 or other device may continue the session with the recovery manager 208 and receive a request of copying the operating system image from the portable communication device 102. Examples of the operating system image may include the operating system 212, except for any data or codes desired to keep secret from the portable communication device 102, e.g., the private data. In another embodiment, the operating system image may be obtained from a third party, e.g., an online source, and pre-stored in the portable communication device 104. In yet another embodiment, the operating system image may be copied from the portable communication device 102 before the operating system 202 is crashed. In block 324, the recovery manager 218 or other device may obtain the operating system image using the read/write module 219, and send the operating system image to the portable communication device 102.

It should be understood that other embodiments may implement other technologies for the system and method as discussed above. In an embodiment, the process of displaying the operating system being crashed on the screen and waiting for the user to press the key may be omitted. On the contrary, when the system detection module 204 detects that the operating system 202 is crashed, the system detection module 204 or other device may send the recovery agent 205 with the request of recovering the operating system, in response to which, the recovery agent 205 can start connecting with the portable communication device 104 and recover the operating system. In another embodiment, the portable communication device 102 may recover the operating system, even if the operating system 202 hasn't been crashed. For example, during the system boot process, the user may initiatively request the operating system recovery (e.g., through pressing a special key), rather than requesting the recovery after receiving the notification of the operating system being crashed.

While the disclosure has been illustrated and described in detail in the drawings and foregoing description, such an illustration and description is to be considered as exemplary and not restrictive in character, it being understood that only illustrative embodiments have been shown and described and that all changes and modifications consistent with the disclosure and recited claims are desired to be protected.
