Description

Communication terminal, base station, system and method

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication terminal, a base station, a system, and a method.

Background

Volte (voice over lte) is a voice service based on IMS (Internet Protocol Multimedia Subsystem). IMS has become a core network standard architecture in the full IP (Internet Protocol) era because it supports multiple access and rich multimedia services. After the development and maturity of the last years, IMS has become the mainstream choice for the improvement of the fixed Voice domain, Voice Over Broadband (Broadband Voice), PSTN (Public Switched Telephone Network) Network, and is also determined by 3GPP, GSMA as the standard architecture of mobile Voice. VoLTE is an IP data transmission technology, a 2G/3G network is not needed, all services are borne on a 4G network, and the unification of data and voice services in the same network can be realized. In other words, the 4G network not only provides high-rate data services, but also provides high-quality data calls, which requires VoLTE technology to implement.

However, when the user uses VoLTE for a video call, both sides must use terminals supporting VoLTE, and the SIM cards of both sides must open the VoLTE function, otherwise the call will automatically fall back to a normal voice call. Therefore, when a user attempts to perform a video call with another person using VoLTE, if the VoLTE function is not supported by the opposite terminal or the like, the user often has to perform the call by voice, which degrades the user experience.

In addition, even if both terminals support the VoLTE function, the quality of the wireless channel is unstable, and there may be an unexpected situation, for example, the user moves to a corner with poor signal quality, or the user suddenly leaves the coverage of the 4G network, so that the terminal cannot be registered to the VoLTE network for use.

Disclosure of Invention

The technical problem to be solved by the present invention is to provide a terminal, a communication base station, a system and a method by using WiFi, aiming at the above-mentioned defect, when a user uses VoLTE to perform a video call, both of them must use a terminal supporting VoLTE function or fall back to voice communication due to signal reasons during VoLTE use.

In order to achieve the above object, the present invention provides a communication terminal, which includes a first transmission module and a second transmission module, wherein the detection module:

and the first transmission module is used for transmitting data after establishing connection with the communication base station.

The detection module is used for detecting the data transmission quality of the first transmission module, the second transmission module and the communication base station;

and the second transmission module is used for transmitting data after establishing connection with the communication base station when the data transmission quality between the first transmission module and the communication base station is lower than a first threshold value.

In an optional embodiment, the detecting module is further configured to detect data transmission quality between the first transmission module and the communication base station, where:

the data transmission quality includes a data transmission rate and a bit error rate.

In an alternative embodiment, the data comprises audio data, video data, text data, image data.

In an alternative embodiment, the first transmission module comprises a data network transmission module and the second transmission module comprises a WiFi network transmission module.

Further, the present invention also provides a communication base station, including:

the receiving module is used for receiving a data communication request sent by the first transmission module of the communication terminal;

the detection module is used for detecting the data transmission quality of the communication base station and the communication terminal;

a sending module, configured to send a data communication request to a communication terminal when data transmission quality between the communication base station and the communication terminal is lower than a first threshold, where the data communication request includes data transmitted by a second transmission module;

and the transmission module is used for receiving the data communication request sent by the second transmission module of the communication terminal.

Further, the present invention also provides a communication system, including: a communication terminal as described hereinbefore and a communication base station as described hereinbefore.

Further, the present invention also provides a communication method, where the communication method includes:

sending and receiving data to a base station through a first transmission module;

and when the data transmission quality with the communication base station is detected to be lower than a first threshold value and the data transmission quality between the second transmission module and the base station reaches a second threshold value, transmitting data through the second transmission module.

In an alternative embodiment, the data transmission quality is dependent on the data transmission rate and the bit error rate.

In an optional embodiment, the first transmission module comprises an operator network transmission module, such as an LTE network transmission module, and the second transmission module comprises a WiFi network transmission module.

According to the invention, when the first transmission module of the terminal does not have a data transmission function or the transmission speed of the first transmission module is lower than the threshold value, data communication is realized or the data communication quality is improved through the second transmission module, so that the user experience is greatly improved under the condition of not improving the user cost. Especially, at the present that VoLTE is becoming popular, many terminals still stay in the 3g era, but most households and almost all large shopping malls are equipped with WIFI, and data transmission is performed through WIFI and LTE dual channels or a WIFI single channel, so that user experience of a user on high-definition data communication is improved.

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 a hardware structure of a mobile terminal for implementing various embodiments of the present invention.

The mobile communication 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, and the like. 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 communication 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 digital broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), a data broadcasting system of forward link media (MediaFLO), a 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 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 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 1220, 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 module 151. The image frames processed by the camera 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 1210 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 module 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile communication terminal 100 (e.g., an open or closed state of the mobile communication terminal 100), a position of the mobile communication terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile communication terminal 100, an orientation of the mobile communication terminal 100, acceleration or deceleration movement and direction of the mobile communication terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile communication terminal 100. For example, when the mobile communication 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 1410 as will be described below in connection with a touch screen.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile communication 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 communication 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 communication 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 communication terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile communication 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 communication 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 module 151, an audio output module 152, an alarm module 153, and the like.

The display module 151 may display information processed in the mobile communication terminal 100. For example, when the mobile communication terminal 100 is in a phone call mode, the display module 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 communication terminal 100 is in a video call mode or an image capturing mode, the display module 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 module 151 and the touch pad are stacked on each other in the form of layers to form a touch screen, the display module 151 may serve as an input device and an output device. The display module 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. The mobile communication terminal 100 may include two or more display modules (or other display devices) according to a particular desired embodiment, for example, the mobile terminal may include an external display module (not shown) and an internal display module (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 communication 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 module 153 may provide an output to notify the mobile communication terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like. In addition to audio or video output, the alarm module 153 may provide output in different ways to notify the occurrence of an event. For example, the alarm module 153 may provide an output in the form of a vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm module 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 module 153 may also provide an output notifying the occurrence of an event via the display module 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.

The memory 160 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 the like. Also, the mobile communication 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.

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 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 communication terminal 100 as shown in fig. 1 may be configured to operate using, for example, 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 communication 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 communication terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile communication 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 helps locate at least one of the plurality of mobile communication 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 communication terminals 100. The mobile communication terminal 100 generally participates in conversation, messaging, and other types of communication. 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 BSC275, and the BSC275 accordingly controls the BS270 to transmit a forward link signal to the mobile communication terminal 100.

Based on the hardware structure of the mobile terminal and the communication system, the network access method of the invention is provided with various embodiments. The network access method of the invention accesses the wireless network and the mobile network in parallel after acquiring the wireless network signal and the mobile network signal, namely simultaneously using the wireless network and the mobile network to surf the internet. The wireless network is a WIFI network, and the mobile network is a 2G/3G/4G network.

Compared with the prior art that the wireless network or the mobile network is used for surfing the Internet at the same time, the method and the device have the advantages that the wireless network and the mobile network are used for surfing the Internet at the same time, so that the Internet surfing mode is more flexible, diversified Internet surfing requirements of users can be met, the network bandwidth is widened, and the Internet surfing experience of the users is improved.

The following is a detailed description of specific examples.

First embodiment

Referring to fig. 3, fig. 3 is a block diagram of a communication terminal according to a first embodiment of the present invention.

In this embodiment, the communication terminal 100 includes a first transmission module 10a and a detection module 20, a second transmission module 10 b;

the first transmission module 10a is configured to transmit data after connecting with the communication base station BS 270.

In the present embodiment, the communication terminal 100 includes a first transmission module 10a and a second transmission module 10 b; in some cases, there may be a case where the communication terminal 100 includes the first transmission module 10a and the second transmission module 10b, but the first transmission module 100a is out of function.

The detecting module 20 is configured to detect data transmission quality between the first transmission module 10a and the second transmission module 10b and the communication base station BS 270;

in this embodiment, the detecting module 20 is configured to detect the data transmission quality between the first transmission module 10a and the second transmission module 10b and the communication base station BS270, and in an alternative embodiment, the data transmission quality depends on a data transmission rate and a bit error rate, and the larger the data transmission rate, the smaller the bit error rate, the higher the data transmission quality.

The second transmission module 10b is configured to, when the data transmission quality between the first transmission module 10a and the communication base station BS270 is lower than a first threshold, establish a connection with the communication base station BS270 and then transmit data. .

In this embodiment, it should be noted that the threshold, also called a critical value, refers to the lowest value or the highest value that an effect can generate. In this embodiment, the size of the threshold is not necessarily fixed and is affected by various environmental conditions; in this embodiment, the second threshold is a speed at which the second transmission module 10b can effectively transmit data.

In an optional embodiment, in this embodiment, when the communication terminal 100 is in a data call, a situation of signal degradation suddenly occurs, that is, when the data transmission quality of the first transmission module 10 of the communication terminal 100 is lower than a first threshold, if the communication terminal 100 detects that the data transmission quality of the second transmission module 10b is higher than a second threshold, the communication terminal sends data that can be transmitted through the second transmission module to the base station BS 270.

In one embodiment, the first transmission module 10a comprises an operator network transmission module, such as an LTE network transmission module, and the second transmission module 10b is a WiFi network interface. The transmitted data includes audio data, video data, text data, and image data, such as VoLTE calls carried over an LTE network.

In this embodiment, when the first transmission module 10a of the communication terminal 100 does not have the data transmission function or when the transmission quality of the first transmission module 10a is lower than the first threshold, the second transmission module 10b compensates for the inability of performing data communication or improves the data communication quality. The invention can greatly improve the user experience without improving the user cost. Especially, at the present that VoLTE is becoming popular, many terminals still stay in the 3G era, but most households and almost all large shopping malls are equipped with WIFI, and data transmission is performed through WIFI and LTE dual channels or a WIFI single channel, so that user experience is improved.

Second embodiment

Referring to fig. 4, fig. 4 is a schematic diagram of a communication base station module according to a second embodiment of the present invention.

Referring to fig. 5-1, fig. 5-2, and fig. 5-3, fig. 5-1 is a schematic view of a communication system under normal conditions according to a third embodiment of the present invention, fig. 5-2 is a schematic view of a communication system according to the third embodiment of the present invention, and fig. 5-3 is a control flow diagram of a communication terminal in the communication system according to the third embodiment of the present invention.

In this embodiment, the communication system includes at least one communication terminal 100, at least one communication base station BS 270;

the communication base station BS270 receives a data communication request sent by the first communication terminal 100A to the second communication terminal 100B; in this embodiment, it should be noted that the data communication request sent from the first communication terminal 100A to the second communication terminal 100B needs to be processed by the communication base station.

When the communication base station BS270 detects that the data transmission speed of the first communication terminal 100A and/or the second communication terminal 100B is lower than the first threshold, the first communication terminal 100A and/or the second communication terminal 100B is notified to establish a communication channel through the second transmission module 10B;

when the first communication terminal 100A and/or the second communication terminal 100B detects that the speed of accessing the network by the second transmission module 10B reaches the second threshold, the first communication terminal 100A and/or the second communication terminal 100B establishes a communication channel with the communication base station BS270 through the second transmission module 10B.

For convenience of explanation of the present embodiment, video communication between the

communication terminals

100A and 100B through VoLTE is taken as an example as follows. First, a brief description will be given of a procedure when a VoLTE terminal performs video communication with a non-VoLTE terminal.

As shown in fig. 5-1, the communication terminal 100A has VoLTE capability, and is registered in a VoLTE network provided by the base station BS 2701; the communication terminal 100B is not VoLTE capable and is registered in the voice network provided by the base station BS 2702.

The communication terminal 100A initiates a request for a VoLTE video call to the communication terminal 100B, which is sent to the base station BS2702 through the base station BS 2701;

after receiving the video call request, the base station BS2702 detects that the communication terminal 100B can only support voice communication, and then notifies the base station BS2701 that only voice communication can be performed;

after receiving the information, the base station BS2701 notifies the communication terminal 100A that only voice communication is possible;

finally, the communication terminal 100A and the communication terminal 100B establish a voice communication channel through the base stations BS2701 and BS 2702.

The above is the process of performing video communication between the VoLTE terminal and the non-VoLTE terminal under normal conditions. The procedure for video communication between VoLTE terminal and non-VoLTE terminal in this embodiment is as follows

As shown in fig. 5-2, the communication terminal 100A, which has VoLTE capability as in fig. 5-1, is registered in the VoLTE network provided by the base station BS 2701; the communication terminal 100B is not VoLTE capable and is registered in the voice network provided by the base station BS 2702.

after receiving the video call request, the base station BS2702 detects that the communication terminal 100B can only support voice communication, and then the base station BS2702 notifies the communication terminal 100B to use WiFi for communication, and if the communication terminal 100B finds an available WiFi network, sends IP information of the WiFi network to the base station BS 2702; if the communication terminal 100B finds that there is no WiFi network available, the communication terminal 100B also needs to notify the base station BS2702, when ordinary voice communication is used as in fig. 5-1. In this embodiment, the video call request may also be directly sent to the communication terminal 100B without processing after the base station BS2702 receives the video call request, and the communication terminal 100B detects that it only supports voice communication, and thus detects whether there is an available WIFI network, and if the communication terminal 100B finds that there is an available WIFI network, sends the IP information of the WIFI network to the base station BS 2702; if the communication terminal 100B finds that there is no WiFi network available, the communication terminal 100B also needs to notify the base station BS2702, when ordinary voice communication is used as in fig. 5-1.

When the base station BS2702 receives the available IP information sent by the terminal B, the base station BS2701 is notified that the VoLTE communication channel is successfully established;

after receiving the message that the VoLTE communication channel is successfully established, the base station BS2701 forwards the message to the communication terminal 100A;

up to this point, even if the communication terminal 100B originally did not have VoLTE video capability, the communication terminal 100A can perform VoLTE video communication with the communication terminal 100B.

The main architecture and flow for the communication terminal 100B to implement this function is shown in fig. 5-3, where the dashed lines represent control information; the solid line represents the data.

1. The UI module Z01 is mainly used to receive request information of a user. When the user decides to receive VoLTE video communications using the WiFi network, the entire functionality is started by UI module Z01.

2. The UI module Z01 launches a central control module Z02 that is primarily responsible for supporting communications between the other modules, as well as for controlling the other modules. When the user turns on the function, the central control module Z02 starts the signaling receiving module Z04.

3. And after receiving the information sent by the base station BS2702, the antenna receiving module Z05 sends the information to the signaling receiving module Z04. After judging that the received VoLTE video request is received, the signaling receiving module Z04 delivers the message to the central control module Z02.

4. After receiving the message, the central control module Z02 starts the WIFI detection module Z06. The WIFI detection module Z06 is mainly responsible for starting the WIFI network card Z07, accessing the WiFi network, and simultaneously judging the connectivity of the WiFi network, namely whether the WiFi network can access the Internet or not.

5. When the WIFI network card Z07 is started and accesses an effective WiFi network, IP information corresponding to the WIFI network card Z07 is submitted to the central control module Z02; the central control module Z02 also needs to be informed if no active network is accessed.

6. After receiving the information of the WIFI network card Z07, the central control module Z02 assembles the information into an effective signaling format through the signaling sending module Z03, and sends the signaling to the base station through the antenna sending module Z08.

7. When the VoLTE video communication channel is successfully established, the WIFI network card Z07 can obtain video data through the antenna receiving module Z05, and send the video data through the antenna sending module Z08.

In this embodiment, only some changes need to be made to the signaling flow of the terminal that does not support VoLTE capability, such as the communication terminal 100B, and the base station, and the terminal that has VoLTE capability, such as the communication terminal 100A, can implement data communication with the communication terminal 100B without any changes.

Fourth embodiment

Referring to fig. 6-1, fig. 6-2, fig. 6-3, and fig. 6-4, fig. 6-1 is a schematic view of a communication system in a normal situation according to a fourth embodiment of the present invention, fig. 6-2 is a schematic view of a communication system according to a third embodiment of the present invention, fig. 6-3 is a schematic view of another communication system according to the third embodiment of the present invention, and fig. 6-4 is a control flow diagram of a communication terminal according to the present invention. The present embodiment is different from the third embodiment in that: in the third embodiment, one of the terminals does not support data communication, and the terminals of this embodiment all support data communication, but the communication quality is not required due to environmental changes or other reasons, and is improved by WiFi. The same parts of this embodiment as the third embodiment are not described in detail.

In the present embodiment, VoLTE video call is taken as an example. First, the procedure of falling back of VoLTE video call into voice call is introduced. As shown in fig. 6-1, communication terminal 100A and communication terminal 100B are initially engaged in VoLTE video communication.

In some cases, the communication quality of the radio link between the communication terminal 100A and the communication base station BS2701 is greatly degraded (for example, the communication terminal 100A moves to be hidden in a corner, or a sudden heavy rain occurs to make radio wave fading strong), and then the communication base station BS2701 negotiates with the communication terminal 100A, ends video communication, and falls back to voice communication. Meanwhile, the communication base station BS2701 notifies the base station BS2702 of the message.

After receiving the message sent by the base station BS2701, the base station BS2702 negotiates with the communication terminal 100B, and prepares to end the video communication.

When both the base station BS2702 and the communication terminal 100B are ready, the base station BS2702 ends the video communication, and reestablishes a voice communication link for the communication terminal 100A and the communication terminal 100B. By this time, the entire video communication falls back to the voice communication.

In this embodiment, a more moderate link migration policy is performed through the WiFi network, so that it is ensured that the user does not interrupt video communication as much as possible.

As shown in fig. 6-2, as in fig. 6-1, the radio link quality between the communication terminal 100A and the communication base station BS2701 suddenly deteriorates. In contrast, the communication base station BS2701 does not negotiate back to voice communication directly with the communication terminal 100A, but sends information to establish an alternative link to the communication terminal 100A. And only if the alternative link cannot be established, the voice communication is dropped back.

After receiving the request for establishing the alternative link, the communication terminal 100A detects whether there is an available WiFi network. If there is a WiFi network available, the communication terminal 100A transmits IP information of the WiFi network to the communication base station BS 2701.

After receiving the alternative link information sent by the communication terminal 100A, the communication base station BS2701 migrates the original VoLTE link, that is, sends VoLTE video data to the access point connected to the communication terminal 100A through the router, and then the access point is responsible for sending the data to the communication terminal 100A. By the mode, even if a scene with suddenly poor signal quality occurs, video communication cannot be immediately interrupted, and user experience is improved.

Finally, as shown in fig. 6-3, when the quality of the wireless link is improved again, the communication terminal 100A may negotiate with the communication base station BS2701 to migrate the VoLTE link back again, and at this time, no VoLTE video data is transmitted through the router.

The main architecture and flow for the terminal to implement this function is shown in fig. 6-4, where the dashed lines represent control information; the solid line represents the data.

1. The UI module Y01 is mainly used to receive request information of a user. When the user decides to migrate the VoLTE video communication channel using the WiFi network, the whole function is started by UI module Y01.

2. UI module Y01 launches central control module Y02, central control module Y02 is primarily responsible for supporting communications between the other modules, as well as for controlling the other modules. When the user turns on the function, the central control module Y02 starts the signaling receiving module Y04.

3. And after receiving the information sent by the base station BS270, the antenna receiving module Y05 sends the information to the signaling receiving module Y04. And after judging that the received request is the request for establishing the alternative link, the signaling receiving module Y04 delivers the message to the central control module Y02.

4. After receiving the message, the central control module Y02 starts the WiFi detection module Y06. The WiFi detection module Y06 is mainly responsible for starting the WiFi network card Y07 and accessing the WiFi network, and meanwhile, judging the connectivity of the WiFi network, namely whether the WiFi network can access the Internet or not. Meanwhile, the central control module Y02 needs to activate the channel quality detection module Y09.

5. When the WiFi network card Y07 is started and an effective WiFi network is accessed, IP information corresponding to the WiFi network card Y07 is submitted to the central control module Y02; the central control module Y02 also needs to be informed if no active network is accessed.

6. After receiving the information of the WiFi network card Y07, the central control module Y02 assembles the information into an effective signaling format through the signaling sending module Y03, and sends the signaling to the base station through the antenna sending module Y08.

7. When the VoLTE video communication channel is successfully established, the WiFi network card Y07 can obtain video data through the antenna receiving module Y05, and send the video data through the antenna sending module Y08.

8. When the channel quality detection module Y09 judges that the wireless channel quality is good enough, the central control module Y02 is informed; after receiving the message, the central control module Y02 assembles a request frame for VoLTE link relocation through the signaling sending module Y03, and sends the request frame to the base station through the antenna sending module Y08.

9. When the base station BS270 determines that the VoLTE link can be migrated back, it sends back information to the communication terminal 100. At this time, the antenna receiving module Y05 receives the information. The antenna receiving module Y05 submits the received information to the signaling receiving module Y04, and when the module determines that the VoLTE link transition-back response message is replied by the base station BS270, the module notifies the central control module Y02.

10. The central control module Y02 turns off the WiFi detection module Y06 and the WiFi network card Y07. At this time, the terminal no longer transmits VoLTE video data using the WiFi network, but returns to the state of initially communicating directly with the base station BS 270.

The embodiment aims at the problem that the communication quality of a plurality of terminals with data communication functions is suddenly deteriorated in some occasions, and the data communication quality is improved through WiFi, especially in the VoLTE communication process, the communication quality can be improved through WiFi.
