Description

[0001] UMA TERMINAL AND BATTERY CONSUPTION SAVING METHOD THEREOF [0002]

The present invention relates to a UMA (Unlicensed Mobile Access) terminal capable of reducing battery consumption and a method for reducing battery consumption.

The mobile terminal may be configured to perform various functions. Examples of such various functions include a data and voice communication function, a function of photographing a video or a moving image through a camera, a voice storage function, a music file playback function through a speaker system, and an image or video display function.

Some mobile terminals include additional functions to execute games, and some other mobile terminals are also implemented as multimedia devices. Moreover, recent mobile terminals can receive a broadcast or multicast signal to view a video or television program.

In addition to the above functions, efforts to support and increase the functions of the current mobile terminal are continuing. Such efforts include not only changes and improvements in the structural components that form the mobile terminal, but also additions and improvements of software and hardware.

Recently, some service providers in Europe are implementing UMA (Unlicensed Mobile Access) service, which provides low-cost communication to users on a cell-by-cell basis. The UMA service not only provides communication through a wireless LAN (WiFi) but also provides a fixed-mobile convergence (FMC) through interworking with an existing cellular network. A dedicated UMA terminal is required to receive the UMA service. The UMA terminal is fixed to "UMA preferred" when the network access node is manufactured.

However, since the UMA service is advantageous in that the communication fee is cheap, the WiFi network connection is not designed to consume low power in consideration of mobility, so that power consumption is very large unlike the conventional cellular network. In other words, in Europe there are several operators offering UMA services, and users frequently travel to nearby countries. Therefore, when UMA service is used in an environment like Europe, the UMA terminal needs to search for the mode frequently, so the battery is consumed as much. For example, when connected to a WiFi network, it consumes about 2 to 3 times more battery power in a standby state than in a cellular network, and is up to 6 times as large during a call.

Currently, only some operators in Europe (Orange or T-Mobile) offer UMA services. Therefore, when a service is provided from most of the non-UMA cellular service providers which do not provide the UMA service within the home country or from the local station to the other station, the UMA terminal unnecessarily performs the WiFi network search. In this case, battery consumption is caused by the unnecessary WiFi network search.

It is an object of the present invention to provide a UMA terminal capable of reducing battery consumption in a UMA service and a method for reducing battery consumption.

According to another aspect of the present invention, there is provided a battery saving method for a UMA terminal, the method comprising: registering a new network when a user moves to a new network or uses a SIM in a new network; Receiving the provider network information from the registered network and determining the type of the network; And changing the menu status of the network connection mode (NAM) automatically or according to the user selection based on the determined network type.

Preferably, the provider network information includes a mobile country code (MCC) and a mobile network code (MNC).

Preferably, the provider network type includes a UMA provider network and a non-UMA provider network.

Preferably, when the menu state of the network connection mode (NAM) is performed according to the user's selection, a pop-up message is displayed.

Preferably, the menu state change of the network connection mode (NAM) changes the network connection mode (NAM) from UMA Preferred to GERAN / UMTS Only when the corresponding network type is changed from the UMA provider network to the non-UMA provider network, When the network type is changed from a non-UMA carrier network to a UMA carrier network, the network connection mode (NAM) is changed from GERAN / UMTS Only to UMA Preferred.

In order to achieve the above object, a UMA terminal according to an embodiment of the present invention includes: a memory for storing business network information; And a control unit for discriminating the type of the network based on the provider network information and changing the menu state of the network connection mode (NAM) automatically or according to the user selection according to the determined network type.

Preferably, the provider network information includes a country code (MCC) and a network code (MNC).

Preferably, the network registration is performed when the user moves to a new network or uses a SIM of a new network.

Preferably, the controller changes the network connection mode (NAM) from UMA Preferred to GERAN / UMTS Only when the corresponding network type is changed from the UMA provider network to the non-UMA provider network; If the network type is changed from a non-UMA operator network to a UMA operator network, the network connection mode (NAM) is changed from GERAN / UMTS Only to UMA Preferred.

According to the embodiment of the present invention, when the UMA terminal registers in the network (moves to a new network or uses a SIM in a new network), the network connection mode (UMA provider network or non-UMA provider network) (NAM) is changed automatically or according to the selection of the user, thereby reducing consumption of the battery in the standby state.

At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current position in real time.

An audio / video (A / V) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame such as a still image or a moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display module 151.

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated in the process of receiving an external sound signal.

Hereinafter, the mobile terminal related to the present invention will be further described with reference to FIGS. 2 and 3 in view of the components according to the outline. Hereinafter, for simplicity of explanation, a slider type mobile terminal will be described as an example among various types of mobile terminals such as a folder type, a bar type, a swing type, a slider type, and the like. Therefore, the present invention is not limited to a slider type mobile terminal but can be applied to all types of mobile terminals including the above-mentioned type.

2 is a perspective view of a mobile terminal according to an embodiment of the present invention.

The mobile terminal 100 of the present invention includes a first body 200 and a second body 205 configured to be slidable along at least one direction on the first body 200. In the case of a folder phone, the mobile terminal 100 may include a first body and a second body configured to fold or unfold at least one side of the first body.

The state where the first body 200 is disposed in a state of being overlapped with the second body 205 may be referred to as a closed configuration and the first body 200 may be referred to as a second body 205 ) May be referred to as an open configuration.

The mobile terminal 100 mainly operates in the standby mode in the closed state, but the standby mode is also released by the operation of the user. The mobile terminal 100 operates mainly in a communication mode in an open state, but is also switched to a standby mode by a user's operation or a predetermined period of time.

The casing (casing, housing, cover, etc.) constituting the outer appearance of the first body 200 is formed by the first front case 220 and the first rear case 225. Various electronic components are installed in a space formed by the first front case 220 and the first rear case 225. At least one intermediate case may be additionally disposed between the first front case 220 and the first rear case 225.

The cases may be formed by injection molding of a synthetic resin or may be formed of a metal material such as stainless steel (STS) or titanium (Ti).

The display unit 151, the sound output module 152, the camera 121 or the first user input unit 210 may be disposed in the first body 200, specifically, the first front case 220.

Since the display unit 151 has already been described with reference to FIG. 1, a detailed description will be omitted for the sake of simplicity.

The sound output module 152 may be implemented in the form of a speaker.

The camera 121 may be implemented to suitably photograph an image or a moving image for a user and the like.

As in the case of the first body 200, the case constituting the outer appearance of the second body 205 is formed by the second front case 230 and the second rear case 235.

The second user input unit 215 may be disposed on the front surface of the second body 205, specifically, the second front case 230.

The third user input unit 245, the microphone 122, and the interface unit 170 may be disposed in at least one of the second front case 230 and the second rear case 235.

The first to third user input units 210, 215, and 245 may be collectively referred to as a user input unit 130 and may be employed in any manner as long as the user operates in a tactile manner with a tactile impression .

For example, the user input unit may be implemented by a dome switch or a touch pad capable of receiving a command or information by a push or a touch operation of a user, or may be a wheel, a jog type, a joystick, or the like Can also be implemented.

In a functional aspect, the first user input unit 210 is for inputting commands such as start, end, scrolling, etc., and the second user input unit 215 is for inputting numbers, letters, symbols and the like.

A power supply unit 190 for supplying power to the mobile terminal 100 is mounted on the second rear case 235 side.

The power supply unit 190 may be detachably coupled to a rechargeable battery, for example, for charging.

3 is a rear perspective view of the mobile terminal of FIG.

Referring to FIG. 3, a camera 121 may be further mounted on the rear surface of the second rear case 235 of the second body 205. The camera 121 of the second body 205 has a photographing direction which is substantially opposite to that of the camera 121 of the first body 200 and a different pixel from the camera 121 of the first body 200 Lt; / RTI >

For example, the camera 121 of the first body 200 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and transmit it to the other party, Since it is often the case that a subject is photographed and not immediately transferred, it is preferable to have a high pixel.

A flash 250 and a mirror 255 may be additionally disposed adjacent to the camera 121 of the second body 205. The flash 250 illuminates the subject when the subject of the subject is photographed by the camera 121 of the second body 205. The mirror 255 allows the user to illuminate the user's own face or the like when the user intends to take a picture of himself / herself (self-photographing) using the camera 121 of the second body 205.

The second rear case 235 may further include an acoustic output module 152.

The sound output module 152 of the second body 205 may implement a stereo function together with the sound output module 152 of the first body 200 and may be used for a call in a speakerphone mode.

In addition, an antenna 260 for receiving broadcast signals may be disposed on one side of the second rear case 235 in addition to the antenna for communication. The antenna 260 may be installed to be detachable from the second body 205.

A portion of the slide module 265 that slidably couples the first body 200 and the second body 205 is disposed on the first rear case 225 side of the first body 200.

The other part of the slide module 265 may be disposed on the second front case 230 side of the second body 205 and may not be exposed to the outside as in this figure.

In the above description, the second camera 121 and the like are disposed on the second body 205, but the present invention is not limited thereto.

For example, at least one of the configurations 260, 121 to 250, and 152 described as being disposed in the second rear case 235, such as the camera 121 of the second body, It is also possible that the first rear case 225 is mounted to the rear case 225. In such a case, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state is protected by the second body 205. Further, even if the camera 121 of the second body is not separately provided, the camera 121 of the first body may be configured to be rotatable so that the camera 121 of the second body can be photographed up to the photographing direction .

The terminal 100 shown in Figs. 1 to 3 is operable in a communication system capable of transmitting data through a frame or a packet, including a wired / wireless communication system and a satellite-based communication system .

Hereinafter, a communication system capable of operating a terminal according to the present invention will be described with reference to FIG.

However, the present invention is applicable to all communication systems including CDMA wireless communication systems.

4, the CDMA wireless communication system includes a plurality of terminals 100, a plurality of base stations (BSs) 270, and base station controllers (BSCs) 275 , And a mobile switching center ('MSC') 280. MSC 280 is configured to be coupled to a Public Switched Telephone Network (" PSTN ") 290, and is also configured to be coupled to BSCs 275. BSCs 275 may be coupled in pairs with BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs 275 may be included in the system shown in FIG.

Each BS 270 may comprise at least one sector, and each sector may comprise an omnidirectional antenna or an antenna pointing to a particular direction of radial from BS 270. [ In addition, each sector may include two or more antennas of various types. Each BS 270 may be configured to support a plurality of frequency assignments and each of the plurality of frequency assignments has a specific spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. BS 270 may be referred to as a Base Station Transceiver Subsystem (BTSs). In this case, the word "base station" may be referred to as a combination of one BSC 275 and at least one BS 270. [ The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

In addition, FIG. 4 illustrates several Global Positioning System ('GPS') satellites 300. The satellites 300 help to locate at least one of the plurality of terminals 100. Although two satellites are shown in Figure 4, useful location information may be obtained by two or more satellites. The location information module 115 shown in FIG. 1 cooperates with satellites 300 to obtain desired location information. Here, you can track your location using all of the technologies that can track your location, as well as your GPS tracking technology. Also, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

Among the typical operations of a wireless communication system, the BS 270 receives a reverse link signal from the various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the particular base station 270 is processed by the particular base station 270. The data resulting from the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270. The BSC 275 also transmits the received data to the MSC 280 and the MSC 280 provides additional transmission services for connection with the PSTN 290. [ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

The mobile terminal can be connected to a cellular network as well as to a wireless LAN (WiFi) network through the wireless Internet module 113, and the mobile terminal is referred to as a UMA terminal.

The UMA service is a representative service that provides communication through WiFi and provides Fixed-Mobile Convergence (FMC) through interworking with existing cellular networks. A dedicated UMA terminal is required to receive the UMA service. The UMA terminal is fixed to the UMA at the time of manufacture.

5 is a diagram illustrating a NAM menu setting of the UMA terminal.

As shown in FIG. 5, the network connection mode provided in the menu of the UMA terminal is largely composed of a UMA preferred mode, a GERN / UMTS preferred mode, and a GERN / UMTS only mode. The UMA priority mode indicates a mode in which a mobile terminal first connects to a WiFi network and a cellular network is connected if there is no WiFi network. The GERN / UMTS preferred mode is a mode in which a 2G / 3G cellular network is connected first, and a 2G / 3G (second generation / generation) cellular network is connected. In addition, the GERN / UMTS Only mode indicates a mode for connecting only the 2G / 3G cellular network.

6 is a flowchart illustrating a method of reducing battery consumption of a UMA terminal according to the first embodiment of the present invention.

As shown in FIG. 6, in the UMA terminal, the menu state of the network access mode (NAM) for the UMA user at the time of manufacture is set to the UMA preferred mode (S10). Accordingly, the control unit of the UMA terminal firstly accesses the WiFi network in the standby state, and connects to the cellular network in the absence of the WiFi network.

In this case, when the user moves to a new area (or country) and the UMA terminal has to register in the new network (S11), the controller 180 receives the country code (MCC: Mobile Country Code) and a MNC (Mobile Network Code) (S12). Once the MCC and the MNC are received, the control unit 180 compares the MCC and the MNC received previously (S13). If the network is changed, the controller 180 checks whether the network is a non-UMA network (S14). The check may be performed by tabulating the network information with the MCC and the MNC of each country or region, and then confirming the network type from the received MCC and MNC.

If the corresponding network is a non-UMA network, the controller 180 changes the menu state of the NAM shown in FIG. 5 from "UMA Preferred" to "GERAN / UMTS Only (2G / 3G cellular network Quot; connection ") (S15).

Accordingly, the controller 180 can significantly increase the battery usage time in the UMA terminal by preventing the wireless Internet module 113 from unnecessarily searching for the wireless LAN (WiFi) network in the standby mode.

7 is a flowchart illustrating a method of reducing battery consumption of a UMA terminal according to a second embodiment of the present invention. FIG. 6 shows an example of automatically changing the network connection mode (NAM), and FIG. 7 shows an example in which the user can directly change the network connection mode (NAM). Therefore, although the numbers are different, steps S10 to S14 of Fig. 6 are substantially the same as steps S20 to 24 of Fig.

Therefore, if the changed network in step S24 is a non-UMA network, the control unit changes from the current UMA network to the non-UMA network as shown in FIG. 8, / UMTS Only "to the pop-up 50 so that the user can select it (S25). The user selects the "OK" menu by looking at the message displayed in the pop-up 50 (S26). Therefore, the control unit changes the menu state of the network connection mode (NAM) from "UMA Preferred" to "GERAN / UMTS Only" (S27) according to the confirmation of the user.

When the user registers again in the UMA provider network, the controller 180 performs the above-described procedure to automatically change the menu state of the network connection mode (NAM) from "GERAN / UMTS Only" to "UMA Preferred" .

In addition, as shown in FIG. 9, when the user registers again in the UMA carrier network, the present invention displays a predetermined message on the pop-up 51 so that the user can select the original menu state "UMA Preferred ". That is, the control unit 180 displays a message to the user via the pop-up 51 asking whether the UMA network has been changed from the current non-UMA network to the UMA preferred network.

When the user selects the "OK" menu in response to the message, the controller changes the menu status of the network connection mode (NAM) from "GERAN / UMTS Only" to "UMA Preferred".

10 is a flowchart illustrating a method of reducing battery consumption of a UMA terminal according to a third embodiment of the present invention. 10 shows another example of network registration, in which a SIM of a new carrier network is used in a UMA terminal. Therefore, except for step S31, substantially the same as in Fig.

Therefore, according to the present invention, when a UMA terminal registers in a network (moving to a new network or using a SIM in a new network), the network access mode (NAM) is established according to the type of the registered network (UMA provider network or non- ) Is changed automatically or according to the user's selection.

Further, according to an embodiment of the present invention, the above-described method can be implemented as computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Further, the computer may include a control unit of the terminal.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
