## Background
RELATED APPLICATIONS
This application is a nationalization under 35 U.S.C. §371 from International Application Serial No. PCT/CN2011070095, filed Jan. 7, 2011 and published as WO 2012/048536 A1on Apr. 19, 2012, which claims benefit of priority under 35 U.S.C.

TECHNICAL FIELD
The present disclosure relates to a communication technology, in particular to a control method for charging a terminal and an apparatus thereof.
BACKGROUND
Currently, a terminal (such as a mobile phone) is charged by the following two charging modes: {circumflex over (1)} ED after the terminal is full charged, a charging current path is switched off; and {circumflex over (2)} after the terminal is full charged, a battery inside the terminal is subjected to trickle charge, and when the voltage of the battery inside the terminal is reduced to a preset voltage threshold value, the secondary charging is started. The preset voltage threshold value is in the range of 4 to 4.1V.
If the above two charging modes are applied, a terminal is more likely to have the following problems when it has been in a charging state for a long time: in the charging mode {circumflex over (1)}, although a charging current is cut off after charging is completed, the terminal cannot be continuously charged when the terminal carries out a service with high power consumption, the electrical energy of the battery of the terminal is rapidly lost and a charging interval is shortened; and in the charging mode {circumflex over (2)}, after the charging is completed, a charging circuit cannot be normally switched off and the terminal would be kept in the charging state for a long time, thereby causing the heating of the terminal body, resulting in an energy waste, even generating a potential safety hazard.
By applying the two charging modes to a terminal, the service life of a battery inside the terminal is shortened and the user experience is influenced.

The standby state of the terminal refers to that: when the terminal is in a power-on state, no network side services or terminal local services are initiated, and meanwhile, no user operates the terminal. After the terminal enters the standby state for a certain time, the terminal enters a low power consumption mode and an operation current of the terminal is reduced to a low power consumption level and is always kept until the terminal enters the operation state.

The operation state of the terminal refers to that: when the terminal is in the power-on state, the terminal is triggered to initiate a certain or a plurality of services due to trigger events such as an operation performed by a user on the terminal or a request from a network side, or the like, i.e. a service module is triggered to be started and enters a stable operating state. When the terminal is in the operation state, a Central Processing Unit (CPU) inside the terminal starts to operate and the operating current is large and is commonly dozens to hundreds of times of that in the standby state. The initiated services include wireless services and terminal local services, wherein the wireless services usually include telephone call, short message, Internet surfing, online game, CMMB, GPS or the like; and the terminal local services commonly include local game, file editing, alarm clock setting or the like.

In the embodiment, in a full-charged state of the terminal, when the terminal is determined to be in the operation state, the charging circuit of the terminal is controlled to be in the switching-on state and the charger continues to supply power to the terminal so as to fill up the electric energy consumed due to operation of the terminal, avoid the start of secondary charging caused by rapid power consumption when the terminal is in the operation state, and prolong the service life of a battery of the terminal; and when the terminal is determined to be in the standby state, the charging circuit of the terminal is controlled to be in the switching-off state so as to avoid a heating phenomenon of the terminal, which is generated when the charging circuit is switched on for a long time, and save a great quantity of energy and improve the charging safety of the terminal.
