Detailed Description
The operating system of the handheld device and the operating system of the desktop device provide many similar functions, such as scheduling processor resources, managing memory, loading programs, managing input/output, and building user interfaces. But because handheld devices are often used to handle simpler tasks, their operating systems are somewhat simpler and much smaller.
The handheld operating system is typically small and may be stored on a read-only memory. The operating system of the handheld device can be used almost immediately when the device is turned on, since it is not necessary to load the operating system from the hard disk into the RAM. The operating system of the handheld device may provide embedded touch screens, handwriting input, wireless networking, and cellular communications.
Taking a smart phone as an example, whether a mobile phone is a smart phone is determined, and whether the mobile phone supports functions of MP3, HTML page browsing, external memory card insertion, and the like is not determined, but whether the mobile phone is provided with an operating system. That is, one needs to see the program extensibility of the operating system to see if it can support the installation and application of third party software.
At present, there are various types of handheld devices, such as a mobile phone, a tablet computer, a PDA, and even a notebook, which are popular for people due to their convenience in carrying, but they are also convenient to be lost or stolen while being convenient to carry.

TDD mode has not been emphasized on the whole in FDD mode in first and second generation mobile communication systems. However, due to the need for new services and the development of new technologies, and many advantages of the TDD mode, the TDD mode will be increasingly emphasized.
The working principle of time division duplex is as follows: TDD is a duplex scheme of a communication system for separating a reception channel and a transmission channel (or uplink and downlink) in a mobile communication system. In the TDD mode mobile communication system, the receiving and transmitting are in different time slots of the same frequency channel, namely carrier, and the receiving and transmitting channels are separated by using the guaranteed time; in the FDD mode, the receiving and transmitting are performed on two separate symmetric frequency channels, and the receiving and transmitting channels are separated by a guaranteed frequency band. The characteristics and communication benefits of mobile communication systems employing different duplex modes are different. The uplink and downlink channels in the TDD mode mobile communication system use the same frequency, and thus have reciprocity of the uplink and downlink channels, which brings many advantages to the TDD mode mobile communication system.
Many details of the invention may be changed without departing from its spirit and scope.
