Rf module 150 may include various existing circuit elements for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption/decryption chip, a Subscriber Identity Module (SIM) card, memory, and so forth. The rf module 150 may communicate with various networks such as the internet, an intranet, a wireless network, or with other devices via a wireless network. The wireless network may comprise a cellular telephone network, a wireless local area network, or a metropolitan area network. The Wireless network may use various Communication standards, protocols, and technologies, including, but not limited to, Global System for Mobile Communication (GSM), Enhanced Data GSM Environment (EDGE), wideband Code division multiple Access (W-CDMA), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), bluetooth, Wireless Fidelity (WiFi) (e.g., Institute of Electrical and Electronics Engineers (IEEE) standard IEEE802.11 a, IEEE802.11 b, IEEE 802.2.1 g, and/or IEEE802.11 n), Voice over Internet Protocol (VoIP), world wide Internet Microwave Access (Microwave for Wireless Communication), other suitable protocols for short message service (Max), and any other suitable Communication protocols, and may even include those protocols that have not yet been developed.

The positioning module 112 is used for acquiring the current position of the terminal 10. Examples of the positioning module 112 include, but are not limited to, a global positioning satellite system (GPS), a wireless local area network-based positioning technology, or a mobile communication network-based positioning technology.

The camera module 114 is used to take a picture or video. The pictures or videos taken may be stored in the memory 102 and transmitted through the radio frequency module 150.

Audio module 116 provides an audio interface to a user that may include one or more microphones, one or more speakers, and audio circuitry. The audio circuitry receives audio data from the peripheral interface 108, converts the audio data to electrical information, and transmits the electrical information to the speaker. The speaker converts the electrical information into sound waves that the human ear can hear. The audio circuitry also receives electrical information from the microphone, converts the electrical information to voice data, and transmits the voice data to the peripheral interface 108 for further processing. The audio data may be retrieved from the memory 102 or through the radio frequency module 150. In addition, the audio data may also be stored in the memory 102 or transmitted through the radio frequency module 150. In some examples, the audio module 116 may also include an earphone jack for providing an audio interface to a headset or other device.

The screen 118 provides an output interface between the terminal 10 and the user. In particular, screen 118 displays video output to the user, the content of which may include text, graphics, video, and any combination thereof. Some of the output results are for some of the user interface objects. It is understood that the screen 118 may also include a touch screen. The touch screen provides both an output and an input interface between the terminal 10 and a user. In addition to displaying video output to users, touch screens also receive user input, such as user clicks, swipes, and other gesture operations, so that user interface objects respond to these user input. The technique of detecting user input may be based on resistive, capacitive, or any other possible touch detection technique. Specific examples of touch screen display units include, but are not limited to, liquid crystal displays or light emitting polymer displays.

The key module 160 also provides an interface for user input to the terminal 10, and the user can press different keys to cause the terminal 10 to perform different functions.
