Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

For example, the air interfaces used by communication systems include, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (particularly Long term evolution (L TE)), Global System for Mobile communications (GSM), and so forth.

Referring to fig. 2, a CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and Mobile Switching Centers (MSCs) 280, the MSCs 280 are structured to interface with Public Switched Telephone Networks (PSTNs) 290, the MSCs 280 are also structured to interface with the BSCs 275, which may be coupled to the base stations 270 via backhaul lines, which may be structured according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame relay, HDS L, ADS L, or xDS L, it will be appreciated that a system as shown in fig. 2 may include a plurality of BSCs 2750.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.

Example one

As shown in fig. 3, a first embodiment of the present invention provides an automatic alarm method for a mobile terminal loss, which includes:

step 310, detecting that the mobile terminal is in a lost state.

Specifically, a trigger condition for the mobile terminal being lost is set in advance and stored in the memory 160. When the trigger condition is reached, it is detected that the mobile terminal is in a lost state.

More specifically, referring to fig. 4, step 310 further includes:

step 410, receiving the short message.

Specifically, the short messages sent by other mobile terminals are received, and the phone numbers of the other mobile terminals may be contact phone numbers stored in the mobile terminals or strange phone numbers.

In practical application, the owner usually finds that the mobile terminal is forgotten and lost or stolen by others and lost. When the owner finds that the mobile terminal is lost, a short message is sent to the mobile terminal at the first time, which causes two situations, one is: the owner and the friend are together, the mobile terminal of the friend is used for sending short messages to the mobile terminal of the owner, and the received short message number is the contact phone number stored in the address list; the other situation is that: the owner alone sends a short message to the mobile terminal of the owner by using the mobile terminal of a stranger, and the received short message number is a strange telephone number.

Step 420, determining whether the content of the short message is the same as the preset content of the short message, if so, entering step 430.

Specifically, the short message content triggering the loss mode is preset, and the short message content is similar to the verification password and can be one of numbers, characters and symbols or any combination thereof. And judging whether the content of the received short message is the same as the preset short message content (verification password), if so, entering the step 430, and if not, failing to judge that the mobile terminal is in a lost state.

Step 430, determining that the mobile terminal is in a lost state.

Specifically, when the content of the short message is the same as the preset content of the short message, it is determined that the mobile terminal is in a lost state. After step 430, step 320 is triggered.

When the content of the short message is different from the preset content of the short message, the short message may be a short message sent by other people or a harassing short message, it cannot be determined that the mobile terminal is in a lost state, and the process is ended.

Step 320, determining whether the electric quantity of the mobile terminal is greater than a preset electric quantity threshold, if so, entering step 330, and if not, entering step 340.

Specifically, the current electric quantity of the mobile terminal is obtained, and whether the current electric quantity is greater than a preset electric quantity threshold is judged, if yes, step 330 is performed, and if not, step 340 is performed.

In step 330, an alarm signal is generated to alarm.

Specifically, when the mobile terminal is in a lost state, an alarm mode is entered. In the alarm mode, at least the following seven alarm modes are adopted to achieve the purpose of reminding people around the mobile terminal.

First, an alarm signal is issued in such a manner as to generate a sound signal for a ringtone alarm, which is prestored in the memory 160. The alarm is connected with a loudspeaker of the mobile terminal, and the sound signal is amplified through the loudspeaker, so that the sound signal can be widely spread. The sound signal may be set to a sound with a distinct alarm characteristic, such as: police car enforcement sounds, pre-stored "thief catching" sounds, default alarm sounds.

Secondly, aiming at the mobile terminal with an indicator light, the light alarm is carried out by sending out an alarm signal in a mode of generating light flicker. The manner in which the light flashes may be a light with a noticeable vigilance, such as: the 'red' and 'blue' lights similar to the warning lights flash alternately, etc.

Thirdly, the light alarm is given out by generating sound signals and flashing light. Generating an alarm in combination with the first and second ways described above.

Fourthly, an alarm signal is sent out in a vibration mode to alarm.

Fifthly, an alarm signal is sent out to alarm in a mode of generating sound signals and vibration.

Sixth, an alarm signal is generated to give an alarm in a manner of generating light flickering and vibration.

Seventh, an alarm signal is generated to give an alarm in a manner of generating a sound signal, a light blinking and a vibration.

Further, in the alarm mode, the functions of all keys or/and touch keys of the mobile terminal are shielded, so that the current holder (thief) of the mobile terminal cannot operate the mobile terminal.

Further, in the alarm mode, only incoming calls are allowed to be received, so that the owner can make an incoming call in time to contact the current holder of the mobile terminal, and cannot normally operate other functions of the mobile terminal.

And 340, backing up the data in the mobile terminal to the cloud.

Specifically, when it is determined that the electric quantity of the mobile terminal is less than or equal to the preset electric quantity threshold, which indicates that the electric quantity of the mobile terminal is not enough to generate an alarm, data in the mobile terminal is backed up to a cloud account of the mobile terminal owner, for example: contact person modes in the address list, short message contents, chat records of social application programs, application program lists and the like.

And 350, destroying the data in the mobile terminal and restoring factory settings.

Specifically, after the data in the mobile terminal is backed up to the cloud, the data in the mobile terminal is destroyed and returned to the factory setting, so that lawless persons are not allowed to take the opportunity.

Further, as will be understood by those skilled in the art, since the power of the mobile terminal will gradually decrease, the

steps

320 and 350 are dynamically performed in real time, namely: in the alarm mode, if the initial electric quantity of the mobile terminal is greater than a preset electric quantity threshold value, an alarm signal is generated to alarm, until the electric quantity is less than or equal to the preset electric quantity threshold value, data in the mobile terminal are backed up to the cloud end, the data in the mobile terminal are destroyed, and factory settings are restored, or if the mobile terminal receives a signal for removing the alarm, the alarm is automatically removed.
