Description

Communication method and terminal

Technical Field

The present invention relates to the field of terminals, and in particular, to a communication method and a terminal.

Background

The power of the mobile stations is controlled so that the signal level is maintained substantially equal and the communication quality is maintained at a receivable level when all the mobile stations in the cell reach the base station. The power control is divided into forward and reverse power control, the reverse power control is divided into open-loop power control and closed-loop power control, and the closed-loop power control is subdivided into outer loop power control and inner loop power control. Power control is a key technique in CDMA systems. CDMA systems are interference limited systems in that the transmit power of the mobile station is interference to other users communicating within the cell, so the transmit power of the mobile station is limited to keep the total power level of the system to a minimum. Power control is one of the key technologies in WCDMA systems. Due to the near-far effect and self-interference problems, whether power control is effective directly determines whether the WCDMA system is available.

Power control is one of the most important requirements in cellular systems. The TD-SCDMA system is an interference limited system, and its system capacity is mainly limited by the interference of each mobile station and base station in the system due to near-far effect, so if the signal of each mobile station reaches the base station, the minimum signal-to-noise ratio required for ensuring the communication quality can be achieved and the system synchronization can be maintained, the capacity of the TD-SCDMA system will be maximized. The power control is based on evaluating the received network signal strength or signal-to-noise ratio and other indexes of the receiver end, and timely changes the transmitting power to compensate the path loss and fading in the wireless channel, thereby not only maintaining the communication quality, but also not generating additional interference to other users in the same wireless resource. In addition, power control allows for a reduction in transmitter power, thereby extending battery life. The purpose of power control is to control the power as much as possible without affecting the communication function of the mobile phone, reduce the mutual influence between the mobile phones, and save the power consumption.

However, in the field such as a deep mountain or other remote places, the number of users is small, the number of base stations is small, the strength and quality of network signals cannot be guaranteed, the situation that the mobile phone is out of service often occurs, and if an emergency situation occurs at this time, the user hopes to obtain contact with the outside through all means.

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 "unit", "means", 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, "unit" 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.

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 broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive digital broadcasting by using a digital broadcasting system such as a data broadcasting system of multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO @), terrestrial digital broadcasting integrated service (ISDB-T), and the like. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 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 113 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal.

The short-range communication module 114 is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth (TM), Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee (TM), and the like.

The location information module 115 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 GPS module 115 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 GPS module 115 can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 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 pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. The sensing unit 140 may include a proximity sensor 141 as will be described below in connection with a touch screen.

The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 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 151 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 151 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 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 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 audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like.

For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (incomingmunication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. 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.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 1810 for reproducing (or playing back) multimedia data, and the multimedia module 1810 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 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 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

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 the memory 160 and executed by the controller 180.

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 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. The mobile terminal 100 may include a wireless communication unit 110, an a/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, 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 interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

Referring to fig. 1 and fig. 3, a terminal according to a first embodiment of the present invention further includes: a network signal strength determining unit 51, configured to monitor a network signal strength of the terminal, and determine whether the network signal strength of the terminal is lower than a preset network signal strength value; a user number analyzing and judging unit 53, configured to analyze the number of end users in a preset range, and judge whether the number of end users in the preset range is lower than a preset standard value; and the transmission power increasing unit 55 is configured to increase the transmission power of the terminal to n times of the maximum transmission power when the network signal judging unit judges that the network signal strength of the terminal is lower than the preset network signal strength value and the user number analyzing and judging unit judges that the number of the terminal users in the preset range is lower than the preset standard value, where n is greater than or equal to 1 and less than or equal to 2, for example, 1, 1.2, 1.5 or 2. When the transmitting power is increased, the transmitting power can be increased step by step or can be in place in one step.

The network signal strength determining unit 51 further includes a network signal strength monitoring subunit 52, configured to estimate a distance to the base station by monitoring network signal strength changes of the serving cell and the neighboring cell; and the method is also used for judging the number of the peripheral base stations by analyzing broadcast messages of other cells or base stations. If the network signal strength of the serving cell and the neighboring cell of the terminal changes from strong to weak (for example, when the GSM network reaches-95 dBm), it indicates that the distance from the base station is increasing, that is, the terminal is moving away from the base station, and the network signal strength of the terminal is decreasing; if the number of the peripheral base stations is gradually reduced, the network signal strength of the terminal is reduced. Generally, the preset network signal strength value is based on the broadcast message which cannot be normally analyzed and sent by the base station; the predetermined standard value is less than 100, for example, 5, 45.

The user number analyzing and determining unit 53 is further configured to analyze a broadcast message sent by the base station to obtain the number of terminal users within a preset range, where the broadcast message includes the number of users served by the base station. When the system information is used specifically, the base station broadcasts the number of users served by the base station in the system information, and the terminal obtains the number of people using the terminal at the periphery by analyzing the system information. When the user moves from a place with more people and good signals to a place with few people, the number of people using the peripheral terminals analyzed by the process terminal is decreased gradually.

When the transmitting power is increased, the transmitting power can be increased step by step or can be in place in one step.

Unlike the previous embodiment, the transmission power boosting unit 55 includes: a first transmission power boosting subunit 56, configured to gradually boost the transmission power of the terminal to the maximum transmission power; detecting whether the terminal can receive the feedback of the network where the terminal is located; a second transmit power boosting subunit 58, configured to boost the transmit power of the terminal to n times of the maximum transmit power if the terminal cannot receive the feedback from the network where the terminal is located when the first transmit power boosting subunit is activated, where n is greater than 1 and less than or equal to 2, and in this embodiment, n is 2. In this embodiment, the first transmit power boosting sub-unit 56 and the second transmit power boosting sub-unit 58 boost the transmit power in two steps, so that the feedback of the network can be obtained more quickly without causing additional interference to other users in the same radio resource.

When the transmitting power is increased, the transmitting power can be increased step by step or can be in place in one step.

Different from the two embodiments, in this embodiment, an activation unit 57 is further included to inquire whether to set the boost of the transmission power to an active state if the network signal strength of the terminal is weakened from strong; at this time, only in the active state, the transmission power of the terminal can be boosted by the transmission power boosting unit 55 at a later stage.

Referring to fig. 6, when the network signal strength of the terminal is weakened from strong, whether to set the increase of the transmission power to the active state may be queried through the interface shown in fig. 6; in this interface 11, three keys including an activation key 12 for causing the raising of the transmission power to be in an activated state, a closing key 13 for causing the raising of the transmission power to be in a closed state, and a related key 14 for explaining the use of the raising of the transmission power may be provided; when the user clicks the about key 14, the function pops up, and the user needs to go to an area where personnel are rare and the base station signal is weak, so that the emergency network locking function is provided, and the user needs to activate the function in advance. "

It should be noted that only in the active state, the transmission power of the terminal can be raised later by the transmission power raising unit 55. In addition, when the terminal is far away from the base station, or because the mountain, when the signal loss that trees blockked the result is serious, if the signal that the terminal received the base station and issued is too weak to lead to the unable normal analysis of terminal, except launching the enhancement mechanism, can also design an external antenna addition method that can expand, reserve the port for the terminal, or with UTB or earphone port sharing, the user only needs the metallic substance that will hand-carry, such as necklace, the metal wire of earphone the inside etc. and port connection, in order to reach external antenna's effect, under the certain circumstances of base station transmission network signal intensity, through the ability of reinforcing terminal received signal, the signal is analyzed as far as possible. However, when the signaling sent by the terminal cannot be transmitted to the base station, the general-purpose transmit power boosting unit 55 is generally required to be activated.

Based on the above terminal hardware structure, various embodiments of the method of the present invention are provided.

As shown in fig. 7, a fourth embodiment of the present invention proposes a communication method, including the steps of: s1, monitoring the network signal intensity of the terminal; s2, judging whether the network signal intensity of the terminal is lower than a preset signal intensity value; if not, returning to the step S1, if yes, entering the step S3, and analyzing the number of the terminal users in the preset range; then, as shown in step S4, it is determined whether the number of end users in the preset range is lower than a preset standard value; if yes, in step S5, increasing the transmission power of the terminal to n times of the maximum transmission power, where n is greater than or equal to 1 and less than or equal to 2; if not, the process returns to step S2 to continuously determine whether the service of the terminal is lower than the preset network signal strength value.

In step S1, when the network signal strength of the terminal is monitored, the distance from the base station may be estimated by monitoring the network signal strength changes of the serving cell and the neighboring cell; and analyzing the broadcast messages of other cells or base stations to judge the number of the peripheral base stations and the overall situation of the network. If the network signal strength of the serving cell and the neighboring cell of the terminal changes from strong to weak, it indicates that the distance from the base station is increasing, that is, the terminal is far away from the base station, and the network signal strength of the terminal is decreasing; if the number of the peripheral base stations is gradually reduced, the network signal strength of the terminal is reduced. In step S2, the default rssi value is based on the terminal being unable to parse the broadcast message normally, and is generally less than 100, for example, when the GSM network reaches-95 dBm.

In step S3, the terminal obtains the number of terminal users in the preset range by parsing the broadcast message sent by the base station, where the broadcast message includes the number of users served by the base station. More specifically, the base station broadcasts the number of users served by the base station in the system message, and the terminal obtains the number of people using the terminal in the periphery by analyzing the system message. When the user moves from a place with more people and good signal to a place with less people, the number of people using the peripheral terminals analyzed by the process terminal is decreased until the number of people is lower than the preset standard value in step S4, wherein the preset standard value in the invention is less than 100, such as 8, 30, 60, 80, etc.

The maximum transmission power of the terminal in step S5 is specified in the network communication protocol; for example, the GSM900 handset maximum transmit power level is normally 5(33dBm) and the minimum transmit power level is 19(5 dBm). In this embodiment, n is 1, 1.2, 1.5, or 2. When the transmitting power is increased, the transmitting power can be increased step by step or can be in place in one step.

Referring to fig. 6, when the network signal strength of the terminal is weakened from strong, whether to set the increase of the transmission power to the active state may be queried through the interface shown in fig. 6; in this interface 11, three keys including an activation key 12 for causing the raising of the transmission power to be in an activated state, a closing key 13 for causing the raising of the transmission power to be in a closed state, and a related key 14 for explaining the use of the raising of the transmission power may be provided; when the user clicks the about key 14, the function pops up, and the user needs to go to an area where personnel are rare and the base station signal is weak, so that the emergency network locking function is provided, and the user needs to activate the function in advance. It should be noted that step S5 can be performed only when the increase of the transmission power is activated.

In addition, when the terminal is far away from the base station, or because the mountain, when the signal loss that trees blockked the result is serious, if the signal that the terminal received the base station and issued is too weak to lead to the unable normal analysis of terminal, except launching the enhancement mechanism, can also design an external antenna addition method that can expand, reserve the port for the terminal, or with UTB or earphone port sharing, the user only needs the metallic substance that will hand-carry, such as necklace, the metal wire of earphone the inside etc. and port connection, in order to reach external antenna's effect, under the certain circumstances of base station transmission network signal intensity, through the ability of reinforcing terminal received signal, the signal is analyzed as far as possible. However, when the signaling sent by the terminal cannot be transmitted to the base station, the signaling generally needs to be raised by the general transmit power.

As shown in fig. 8, a second embodiment of the present invention proposes a communication method including the steps of: t1, monitoring the network signal intensity of the terminal; t2, judging whether the network signal intensity of the terminal is lower than a preset signal intensity value; if not, returning to the step T1, if yes, entering the step T3, and analyzing the number of the terminal users in the preset range; then, as shown in step T4, it is determined whether the number of end users in the preset range is lower than a preset standard value; if yes, increasing the transmission power of the terminal to the maximum transmission power as shown in step T5, then entering step T6 to detect whether the terminal can receive the feedback of the network where the terminal is located, and if yes, directly ending as shown in step T7; if not, as shown in the step T8, the transmission power of the terminal is increased to twice the maximum transmission power.

In step T1, when the network signal strength of the terminal is monitored, the distance from the base station may also be estimated by monitoring the network signal strength changes of the serving cell and the neighboring cell; and analyzing the broadcast messages of other cells or base stations to judge the number of the peripheral base stations and the overall situation of the network. If the network signal strength of the serving cell and the neighboring cell of the terminal changes from strong to weak, it indicates that the distance from the base station is increasing, that is, the terminal is far away from the base station, and the network signal strength of the terminal is decreasing; if the number of the peripheral base stations is gradually reduced, the network signal strength of the terminal is reduced. In step T2, the predetermined rssi value is based on that the terminal cannot normally parse the broadcast message, and is generally less than 100, for example, when the GTM network reaches-95 dBm.

In step T3, the terminal obtains the number of terminal users in the preset range by parsing the broadcast message sent by the base station, where the broadcast message includes the number of users served by the base station. More specifically, the base station broadcasts the number of users served by the base station in the system message, and the terminal obtains the number of people using the terminal in the periphery by analyzing the system message. When the user moves from a place with more people and good signal to a place with less people, the number of people using the peripheral terminals analyzed by the process terminal is decreased until the number of people is lower than the preset standard value in the step T4, wherein the preset standard value in the invention is smaller than 100, such as 8, 30, 60, 80, and the like.

The maximum transmitting power of the terminal in the steps T5 and T8 is specified in a network communication protocol; for example, the GTM900 handset maximum transmit power level is normally 5(33dBm) and the minimum transmit power level is 19(5 dBm). When the transmitting power is increased, the transmitting power can be increased step by step or can be in place in one step.

Referring to fig. 6, when the network signal strength of the terminal is weakened from strong, whether to set the increase of the transmission power to the active state may be queried through the interface shown in fig. 6; in this interface 11, three keys including an activation key 12 for causing the raising of the transmission power to be in an activated state, a closing key 13 for causing the raising of the transmission power to be in a closed state, and a related key 14 for explaining the use of the raising of the transmission power may be provided; when the user clicks the about key 14, the function pops up, and the user needs to go to an area where personnel are rare and the base station signal is weak, so that the emergency network locking function is provided, and the user needs to activate the function in advance. It should be noted that the step T5 can be performed only if the increase of the transmission power is activated.

The invention provides a communication method and a terminal, which can enhance the transmitting power of the terminal so as to be in contact with the outside under the condition that a user cannot obtain normal service due to weak base station signals in the field such as a deep mountain or other remote places, and have a certain effect on the safety of outdoor activities of the user.
