Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

The mobile terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like. In the following, it is assumed that the terminal is a mobile terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

Fig. 1 is a schematic diagram of an alternative mobile terminal hardware architecture for implementing various embodiments of the present invention.

The mobile terminal 100 may include a wireless communication unit 110, a user input unit 120, an output unit 130, a memory 140, a controller 150, and a power supply unit 160, etc. Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a mobile communication module 111, a wireless internet module 112, and a location information module 113.

The mobile communication module 111 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 112 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include WLAN (wireless LAN) (Wi-Fi), Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The location information module 113 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module is a GPS (global positioning system). According to the current technology, the location information module 113 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the position information module 113 can calculate the speed information by continuously calculating the current position information in real time.

The user input unit 120 may generate key input data to control various operations of the mobile terminal according to a command input by a user. The user input unit 120 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch panel is superimposed on the display unit 131 in the form of a layer, a touch screen may be formed.

The output unit 130 may include a display unit 131 and the like.

The display unit 131 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 131 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 131 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 131 and the touch panel are stacked on each other in the form of layers to form a touch screen, the display unit 131 may function as an input device and an output device. The display unit 131 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The memory 140 may store software programs and the like for processing and controlling operations performed by the controller 150, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or is to be output. Also, the memory 140 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 140 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and so on. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 140 through a network connection.

The controller 150 generally controls the overall operation of the mobile terminal. For example, the controller 150 performs control and processing related to voice calls, data communications, video calls, and the like. The controller 150 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 160 receives external power or internal power and provides appropriate power required to operate the respective elements and components under the control of the controller 150.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 150. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in memory 140 and executed by controller 150.

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.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the 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 a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

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. 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 to be understood that useful positioning information may be obtained with any number of satellites. The location information module 113 as shown in fig. 1 is generally configured to cooperate with the 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.

Referring to fig. 3, a first embodiment of a wireless lan access apparatus according to the present invention provides a wireless lan access apparatus, including:

and the selection module 10 is configured to obtain a base station to be selected by screening according to the signal strength and the preset condition, which are received by the mobile terminal and sent by each wireless local area network base station.

The invention carries out screening according to the received Wireless Local Area Network (WLAN) signals, automatically starts the Wireless Local Area network access function of the mobile terminal after obtaining the effective base station, accesses the Wireless Local Area network, does not need the mobile terminal to start the Wireless Local Area network access function all the time, does not need the manual operation of a user, and realizes the automatic access of the Wireless Local Area network. The wireless local area network access device may be configured in a mobile terminal.

As an implementation manner, first, when the wlan function of the mobile terminal is in a closed state, the selection module 10 obtains the signal strength of each base station according to the signal sent by each wlan base station received by the mobile terminal, and obtains the base station to be selected by screening according to a preset condition.

In this embodiment, the preset condition is to perform priority ranking on each base station according to the signal strength, and the base station with the priority ranking within the preset range is the base station to be selected. Of course, the preset condition may also be other screening conditions, and may be flexibly configured according to actual needs.

Specifically, when the wlan function of the mobile terminal is in an off state, the mobile terminal actually receives the bs signal and processes the bs information at any time no matter the user is walking or standing still with the mobile terminal.

At this time, the selection module 10 obtains the signal strength of each base station according to the signal sent by each wlan base station received by the mobile terminal.

Then, the selection module 10 performs priority ranking on each base station according to the signal strength of each base station, so that the base station with the strongest signal has the highest priority and the base station with the worst signal has the lowest priority, and thus, the selection module 10 obtains a base station queue arranged according to the priority and the priority ranking of each base station.

Then, the selection module 10 selects a base station with a priority ranking within a preset range as a base station to be selected according to the base station queue, for example, selects a base station with the highest priority ranking three times as the base station to be selected.

Thus, the selection module 10 obtains the base station to be selected. It should be noted that there may be one or more candidate base stations obtained by screening.

And the verification module 20 is configured to verify whether the candidate base station is a valid base station according to a preconfigured record table and the signal strength of the candidate base station.

After the candidate base station is obtained, the verification module 20 verifies whether the candidate base station is a valid base station according to the preconfigured record table and the signal strength of the candidate base station.

As an implementation manner, according to the record table, the verification module 20 obtains a signal strength effective range corresponding to the base station to be selected; and if the signal intensity of the base station to be selected meets the effective range of the signal intensity, judging the base station to be selected as an effective base station.

Note that the log table describes effective ranges of signal strengths of the respective wireless lan base stations to which the mobile terminal has currently connected.

Specifically, the verification module 20 queries a pre-configured record table, and searches for a signal strength effective range corresponding to the candidate base station.

If the valid range of the signal strength corresponding to the candidate base station is not found in the record table, the verification module 20 determines that the current mobile terminal is connected to the candidate base station, and determines that the candidate base station is an invalid base station.

If the valid range of the signal strength corresponding to the candidate base station is successfully found in the record table, the verification module 20 determines whether the signal strength of the candidate base station is within the valid range of the signal strength corresponding to the candidate base station.

If the signal strength of the candidate base station is within the valid range of the corresponding signal strength, the verification module 20 determines that the signal strength of the candidate base station satisfies the valid range of the corresponding signal strength, and the candidate base station is a valid base station.

If the signal strength of the candidate base station is not within the valid range of the corresponding signal strength, the verification module 20 determines that the signal strength of the candidate base station does not satisfy the valid range of the corresponding signal strength, and the candidate base station is an invalid base station.

Thereby, the authentication module 20 obtains the authentication result of the valid base station. One or more effective base stations may be obtained.

And the starting module 30 is configured to control the mobile terminal to access the wireless local area network corresponding to the base station to be selected if the base station to be selected is an effective base station.

After the verification result of the valid base station is obtained, if the valid base station exists in the current base station to be selected, the starting module 30 controls the mobile terminal to start the wireless local area network access function.

After the wlan access function is turned on, since the current active base stations are all base stations to which the mobile terminal has been connected, and account information of the wlan logging in the base station is stored in the record table, the turning-on module 30 may access the wlan according to the account information of each wlan configured in advance.

Therefore, automatic access of the wireless local area network is realized.

In this embodiment, the selection module 10 obtains a base station to be selected by screening according to the signal strength and the preset condition sent by each wlan base station received by the mobile terminal; then, the verification module 20 verifies whether the base station to be selected is an effective base station according to the preconfigured record table and the signal strength of the base station to be selected, so as to remove the base station with poor signal strength and poor wireless local area network; if the base station to be selected is a valid base station, that is, the signal strength of the base station to be selected is within the acceptable range, the start module 30 controls the mobile terminal to start the wireless local area network access function, and access the wireless local area network corresponding to the base station to be selected, so that the automatic access of the wireless local area network is realized. According to the embodiment, the wireless local area network access function does not need to be started all the time by the mobile terminal, automatic screening can be carried out according to the wireless local area network base station received by the terminal, and the wireless local area network access function of the mobile terminal is automatically started to access the wireless local area network after an effective usable base station is obtained, so that the automatic access of the wireless local area network is realized. Moreover, the effective base station obtained by screening can be accessed to the effective wireless local area network after the wireless local area network access function is opened, and the network access efficiency is improved. According to the embodiment, the mobile terminal is automatically accessed to the common wireless local area network, manual operation of a user is not needed, the electric quantity of the mobile terminal cannot be wasted, and the use experience of the user is improved.

Further, referring to fig. 3, a second embodiment of the wlan access device of the present invention provides a wlan access device, based on the first embodiment of the wlan access device of the present invention, the starting module 30 is further configured to,

The present embodiment is different from the first embodiment of the wlan access device of the present invention described above in that: the embodiment verifies the position of the mobile terminal, thereby improving the access success rate of the wireless local area network.

If the base station to be selected is a valid base station, the start module 30 may determine that a wlan base station that the mobile terminal has accessed at present exists, and at this time, in order to further improve the success rate of wlan access, the location of the mobile terminal is obtained.

When the position of the mobile terminal is obtained, the positioning can be carried out through a base station or a data service. In order to accurately position the mobile terminal, the mobile terminal can be positioned through the data service, and more accurate position information can be acquired.

In this embodiment, the record table further records the effective location ranges of the wlan base stations to which the current mobile terminal has been connected. The valid location range is used to determine whether the current mobile terminal has ever connected to the valid base station in the vicinity of the current location.

After the current position of the mobile terminal is obtained, the starting module 30 queries the effective position ranges corresponding to the current effective base stations in the record table.

Then, the start module 30 determines whether the current mobile terminal is located within the valid location range according to the current location of the mobile terminal.

If the current position of the current mobile terminal is within the effective position range of any effective base station, the starting module 30 determines that the mobile terminal is within the effective position range of the effective base station; if the current position of the current mobile terminal is not within the effective position range of any effective base station, the starting module 30 determines that the mobile terminal is not within the effective position range of the effective base station.

Thereby, the opening module 30 obtains a position determination result of the mobile terminal.

After the position determination result of the mobile terminal is obtained, if the mobile terminal is located in the effective position range of an effective base station, the mobile terminal is once connected to the effective base station near the current position, and accesses the wireless local area network, that is, the current effective base station is available historically.

Therefore, it can be considered that the active base station can currently provide the access function of the wireless lan as well, and the network status is available. Then, the starting module 30 starts the wlan access function of the mobile terminal to access the wlan corresponding to the active base station. Thereafter, the mobile terminal can obtain network data based on the accessed wireless local area network, and provide network service for the user.

Further, as an implementation manner, if the current location of the current mobile terminal is not within the effective location range of any effective base station, the mobile terminal never connects the effective base station obtained by screening near the current location, that is, the location of the current mobile terminal is suspicious and is not within the history range of the user. The start module 30 determines that the wlan of each active base station is unavailable and does not turn on the wlan function.
