By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.

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, various embodiments of the present invention are proposed.

As shown in fig. 3, a first embodiment of the present invention provides an apparatus for invoking GPS estimated location information by a mobile terminal, the apparatus comprising:

the GPS invoking module 310 is configured to invoke a GPS according to an operating mode and an activation frequency of a mobile terminal to obtain first location information of the mobile terminal, where the first location information includes first location data and a first time corresponding to the first location data.

Specifically, the apparatus for invoking GPS to estimate location information by the mobile terminal in this embodiment further includes a setting module 340. The setting module 340 is configured to preset a usage scenario of the mobile terminal to determine an operating mode of the mobile terminal. The user sets a usage scenario of the mobile terminal in the setting module 340 in advance, for example: and correspondingly setting working modes corresponding to the use scenes. When the operation mode is set, the operation mode corresponding to the usage scenario one to one may be set, for example: the home mode corresponds to the home mode, the office mode corresponds to the company mode, the shopping mall mode corresponds to the shopping mode, and the playground mode corresponds to the sports mode. In addition, the motion situation can be divided into two modes, for example: "home" and "company" correspond to "static mode", and "mall" and "playground" correspond to "dynamic mode".

The setting module 340 is further configured to preset a GPS activation frequency corresponding to the usage scenario according to the working mode. The activation frequency refers to the frequency of calling the GPS, so that the GPS is prevented from being called all the time, and the power consumption of the mobile terminal are saved. For example, the activation frequency of "static mode" is set to "one hour/time", i.e., GPS is invoked once per hour; the activation frequency of the "dynamic mode" is set to "ten minutes/time", i.e. GPS is invoked every ten minutes.

The GPS calling module 310 periodically calls a GPS according to the detected operating mode and the activation frequency, and the GPS acquires geographic location information, i.e., location data, of the current location according to the current location of the mobile terminal, and at the same time, calls a clock module in the mobile terminal to acquire the current time.

The current position and the current time in this embodiment are dynamic positions and times, that is, when the GPS is called for the first time, the first geographic position information and the corresponding time at that time are obtained, and when the GPS is called for the second time, the second geographic position information and the corresponding time at that time are obtained, and so on. Then, the first geographical location information and the second geographical location information are connected to obtain an activity trace diagram of the mobile terminal, and the activity trace diagram is sent to the data processing module 330 for storage.

And a motion state analysis module 320, configured to record a motion state of the mobile terminal and calculate a motion vector corresponding to the motion state.

Specifically, according to the operating mode of the mobile terminal, the motion state is determined and recorded each time the GPS is activated, for example: static and/or dynamic. The motion vector includes a motion direction and a motion speed. A plurality of geographical information and corresponding times acquired by the GPS calling module 310 each time the GPS is activated are dynamically calculated, thereby determining the moving direction and speed of the mobile terminal.

Taking the working mode as "dynamic mode" and the activation frequency as "ten minutes/time" as an example, assuming that the time when the GPS is called for the first time is 12:00:00 and the geographic location is point a, the motion vector can be calculated by the following two ways:

first, referring to fig. 4, position data obtained by calling a GPS at one time by the GPS calling module 301 is geographic coordinates, in the process of calling the GPS at one time, the mobile terminal obtains coordinates of a point a at a starting position as (0,0), and in the tenth minute as 12:10:00, the mobile terminal arrives at a point B at another position as (4,3), and the unit is meter, then the linear distance from the point a to the point B is 5 meters, and the included angle with respect to the horizontal direction is 37 °. The direction of motion in the motion vector is thus determined to be 37 ° relative to horizontal, with a speed of 0.5m/min (calculated from 5 m/10 min to 0.5 m/min).

Secondly, referring to fig. 5, position data obtained by calling a GPS for one time by the GPS calling module 301 is represented by south, east, west and north, in the process of calling a GPS, the mobile terminal is at a starting position a ', the position of the point a' is in the east-west direction, and in the tenth minute, namely 12:10:00, the mobile terminal arrives at another position B ', the direction of the point B' is 53 degrees north and the moving speed is 0.5 m/min.

Further, when the motion vector is calculated, the average motion direction and the average motion speed of the mobile terminal can be obtained by calling the geographic information acquired by the GPS for multiple times and averaging.

The data processing module 330 is configured to predict second location information of the mobile terminal according to the first location information and the motion vector.

Specifically, the first location information referred to in this embodiment is the location information of the last GPS call, and those skilled in the art can understand that the GPS can also acquire multiple sets of location information before the first location information.

The data processing module 330 estimates the second location information of the mobile terminal according to the following two situations:

firstly, after acquiring first position information and a motion vector when the application program a calls the GPS for the first time, the application program a continues to run in the background, and then the application program a periodically calls the GPS according to the activation frequency, and then the second position information acquired when the application program a calls the GPS for the second time may be acquired again, or may be acquired by integrating and adding the first position information and the motion vector.

Secondly, after the application program B acquires the first position information and the motion vector when the GPS is called for the first time, the application program B is closed, the application program B is restarted after a plurality of time intervals, the position change of the mobile terminal in a plurality of time intervals is calculated firstly compared with the first position information and the motion vector acquired for the previous time, and then the second position information of the mobile terminal is estimated. For example, referring to fig. 4, the geographic position of the mobile terminal at the first position is B (4,3), the moving direction is 37 ° relative to the horizontal direction at a time of 12:10:00, the moving speed is 5m/min, after 20 minutes (12: 30:00) of restarting the application B, the geographic position of the mobile terminal at that time is estimated to be C (12,9), and the linear distance from the point B to the point C is 10 m. The operation mode of the mobile terminal is 'dynamic mode', the activation frequency is 'ten minutes/time', when the GPS is called again, the time is 12:40:00, the mobile terminal moves from the point C to the point D, and the geographic position of the point D is (16, 12). In this embodiment, the point C may be the second position, and the point D may also be the second position.

In practical application, when a plurality of application programs call the GPS at the same time, each application program predicts the second position information according to the corresponding first position and motion vector.

The apparatus for predicting location information by using a GPS for a mobile terminal according to this embodiment calls the GPS through the GPS calling module 310 according to the working mode and the activation frequency of the mobile terminal to obtain first location information of the mobile terminal, the motion state analyzing module 320 records the motion state of the mobile terminal and calculates a motion vector corresponding to the motion state, and the data processing module 330 predicts second location information of the mobile terminal according to the first location information and the motion vector. Therefore, when the GPS is called every time, the information of other positions can be estimated according to the previous position and the motion vector, the time is saved, the power loss caused by frequent calling of the GPS is saved, and the situation that the position information cannot be obtained after the GPS enters a GPS blind area is avoided.

Referring to fig. 6, a second embodiment of the present invention further provides an apparatus for invoking GPS to estimate location information by a mobile terminal. In the second embodiment, the apparatus for invoking GPS to estimate location information by the mobile terminal differs from the first embodiment in that the motion state analysis module 320 includes:

a period setting unit 321 for setting the first period.

In particular, the time length of the first period is less than the activation frequency, e.g. 1 minute, 30 seconds, etc. The period setting unit 321 divides the activation frequency into several first periods each time the GPS is activated.

A motion vector obtaining unit 322, configured to obtain a motion vector of the GPS in the first time period.

Specifically, when the GPS is called once, a motion vector of the GPS continuously operating in each first period is acquired, which mainly includes a motion direction and a motion speed of the mobile terminal. That is to say, within one activation frequency, according to a plurality of first time periods, a plurality of motion directions and motion speeds of the mobile terminal during the plurality of first time periods are obtained, so that the motion trajectory of the mobile terminal may be a straight line or a curve, and the motion speed may be a constant speed or a variable speed. And obtaining the motion vector of the mobile terminal by taking an average value or an arbitrary value.

The mobile terminal of the embodiment invokes a device for estimating location information by using a GPS, sets a first time period by using the time period setting unit 321, and the motion vector acquisition unit 322 acquires a motion vector of the GPS in the first time period. Therefore, the accuracy of the motion vector is improved, the accuracy of the pre-estimated mobile terminal at the second position information is improved, and the method has the advantages of saving time and electricity, quickly positioning, reducing blind areas and providing better use experience for users.

In the third embodiment, the apparatus for invoking GPS to estimate location information by the mobile terminal is different from the second embodiment in that the data processing module 330 includes:

a motion variable estimation unit 331, configured to estimate a motion variable of the mobile terminal according to the motion vector in the first time period.

Specifically, the activity conditions of the mobile terminal in the N first time periods are different, so the motion speed and the motion direction of the mobile terminal are also changed correspondingly, a certain first time period is set as a reference first time period, and then the motion vectors corresponding to the (N-1) first time periods are respectively obtained, and the motion variable of each motion vector is compared with the reference first time period.

And the position information estimation unit 332 is configured to calculate, according to the first position information and the motion variable, a second time when the mobile terminal reaches a second position data or a second position data corresponding to the second time when the mobile terminal reaches the second position data.

Specifically, the estimation of the second location information of the mobile terminal may be divided into two cases, one is to estimate a time when the mobile terminal reaches the second location data, and the other is to estimate the second location data corresponding to the second time.

In practical application, the time when the map-like application program calls the GPS for the previous time to obtain the data is 9:10:00, the location is "home", and the "supermarket" is selected as the second location data, the motion variable calculated by the motion variable estimation unit 331 is 6min, and the time to reach the "supermarket" is 9:16:00 displayed on the mobile terminal.

Further, the time when the application program of the sports fitness class calls the GPS for the previous time is also 9:10:00, the location is "home", and 9:18:00 is selected as the second time, the motion variable estimation unit 332 calculates that the second location data is "mall" after 8min by using "home" as the starting point and according to the motion variables of the motion direction and speed.

The device for predicting the position information by using the GPS for the mobile terminal provided in this embodiment predicts the motion variable of the mobile terminal according to the motion vector in the first time period by using the motion variable predicting unit 331, and calculates, by using the position information predicting unit 332, according to the first position information and the motion variable, to obtain the second time when the mobile terminal reaches the second position data or the second position data corresponding to the second time when the mobile terminal reaches the second position data. Therefore, when the GPS is called every time, the information of other positions can be estimated according to the previous position and the motion vector, the time is saved, the power loss caused by frequent calling of the GPS is saved, and the situation that the position information cannot be obtained after the GPS enters a GPS blind area is avoided.
