Description

Mobile terminal and communication method thereof

Technical Field

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

Background

A long-time call in a high-speed moving process (such as a call on a subway or a train running at a high speed) is generally required to be maintained under the condition of weak signals. During high-speed movement, frequent cell switching must be performed to maintain the call. And under the condition that the signal of the current service cell is weaker and weaker, searching the cell with stronger signal and switching. Therefore, the call drop caused by the fact that the current cell is weak and cannot support the call and no new suitable cell provides service can not occur, and the user experience is not influenced.

For example: when the radio frequency performance of the mobile phone is not good, the channel information of the current cell and the adjacent cell measured by the mobile phone may have errors, and at this time, the signal reported to the base station may have errors or the mobile phone may not receive the instruction for switching to the adjacent cell issued by the base station, or the current channel of the mobile phone is very weak when the base station issues the instruction, so that a call drop occurs. Thus, the dropped call during high speed movement can be summarized as: when the signal of the current service cell is weaker and weaker, no better cell provides service, and the whole call is interrupted.

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 an alternative mobile terminal for implementing various embodiments of the present invention.

The mobile terminal 100 may include the wireless communication unit 110, the sensing unit 140, the memory 160, and the controller 180, 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 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 terminal may obtain cell information sent by the base station through the broadcast receiving module 111.

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. When the mobile terminal performs cell handover, the mobile communication module 112 reports the cell information measured by the mobile terminal to the base station, and the base station makes a decision according to the sum of the reported measurement information.

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 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.

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 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 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 one embodiment, the controller 180 is further connected to the wireless communication unit 110, determines a moving state of the mobile terminal according to the location information module 115, and when it satisfies a preset condition, the controller 180 controls the mobile communication module 112 to perform a related operation. 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 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 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. It is understood that fig. 2 is a communication system architecture diagram of a 2G mobile network, and in the following embodiments of the present invention, a communication system of 3G and 4G mobile networks may also be adopted.

Based on the above-described mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.

Referring to fig. 3, there is provided a first embodiment of a mobile terminal of the present invention, in the present embodiment, the mobile terminal includes:

the judging module 101 is configured to judge a moving state of the mobile terminal, and send a message to the control module when the moving state of the mobile terminal meets a preset condition.

The mobile terminal provided by the embodiment is mainly applied to call processing and is used for processing a call process. It can be understood that the mobile terminal may be a terminal device equipped with a phone card, and in the following embodiments, a mobile phone is taken as an example for detailed description.

Specifically, when the mobile phone is in a call state, it is determined whether the mobile phone is in a call during a high-speed movement, and the determination may be made according to conditions such as GPS information of the mobile phone, corresponding base station information, or the number of times that the mobile phone performs a cell handover within a set time interval closest to the current time, for example, the location information module 115 or the sensing unit 140 in fig. 1. When the mobile phone is in a high-speed moving process for communication, on the basis of the existing communication state protocol, a Flag bit Flag is added and set to be 1, which indicates that the mobile phone is in a high-speed moving process for communication; when the mobile phone is at low speed or hardly moving, the Flag will take 0.

The control module 102 is configured to adjust the control parameter when receiving the message sent by the determining module; the control parameter is the frequency of measuring the channel information of the current service cell and/or the adjacent cell of the mobile terminal.

Specifically, the control module executes corresponding operations according to the values of the flag bits. When the Flag is 1, the control module adjusts the frequency of measuring the channel information of the current serving cell and the neighboring cell. On the basis of the existing mobile terminal call state protocol, a timer is added, and the time interval T1 of the timer can be set according to the mobile phone moving speed or the switching frequency of the serving cell within a set time nearest to the current time, if the mobile phone moving speed is fast or the cell switching frequency is fast, the time period T1 can be set to be a small value, otherwise, a large value can be set. Controlling the frequency of the cell measurement channel may be configured in an uplink frame structure, see fig. 4(a), which is a schematic diagram of a radio frame structure in an embodiment of the present invention, for example, information of the cell measurement channel is configured in an uplink subframe 3 of the radio frame, and in the prior art, only M (M is much smaller than N) radio frames are configured with information of the cell measurement channel among N radio frames sent for the cell measurement channel; in this embodiment, in order to increase the frequency of the scell channel, the structure of the N radio frames to be transmitted is adjusted, as shown in fig. 4(b), X radio frames (where X is greater than the value of M) including subframes configured with the scell channel information are added to the N radio frames, for example, one radio frame configured with the scell channel information may be set at intervals among the N radio frames.

It should be understood that, the method for the mobile terminal to obtain the information of the cell through the message broadcasted by the current serving base station, or obtain the cell information through the way of requesting to allocate the scanning interval or the sleep interval to scan and range the cell, and these methods for measuring the channel information of the current serving cell and the neighboring cell, and the method for the mobile terminal to receive and transmit the base station information, etc. are prior art in the field of communication technology, and are not described herein again.

Based on the above-mentioned embodiment of the invention, referring to fig. 5, the mobile terminal further includes:

a handover module 103, configured to perform cell handover according to the signal strength of the current cell and/or a neighboring cell.

Specifically, in a period of time T1, if the signal of the current cell is lower than or equal to a certain threshold and the signal strength of the neighboring cell is higher than or equal to a certain threshold, the mobile phone actively informs the base station of the measurement information and requests handover, which can be implemented by the mobile communication module 112 in fig. 1, and the base station makes a decision according to the reported measurement information and the channel idle state of the target cell, so that the mobile phone can be handed over to the cell with better signal more smoothly.

With reference to fig. 6, a schematic structural diagram of another mobile terminal is provided in combination with the above embodiment of the present invention, where the mobile terminal includes: a first processing module 201 and a second processing module 202, a judging module 203, a control module 204, a switching module 205 and an associating module 206, wherein the first processing module 201 is connected with a first subscriber identity card 207, and the second processing module 202 is connected with a second subscriber identity card 208.

The judging module 203 is configured to judge a moving state of the mobile terminal, and send a message to the control module when the moving state of the mobile terminal meets a preset condition.

The mobile terminal provided by the embodiment is mainly applied to call processing and is used for processing a call process. It can be understood that, in the following embodiments, a detailed description is given by taking a mobile phone as an example, in this embodiment, the first subscriber identity module card may be a main card, and the second subscriber identity module card may be a sub card, where the number of the sub cards may be set according to actual needs, and in the following embodiments, a detailed description is given by taking the second subscriber identity module card as one card.

Specifically, when the mobile phone is in a call state, it is determined whether the mobile phone is in a call during a high-speed movement, and the determination may be made according to conditions such as GPS information of the mobile phone, information of a corresponding base station, or a frequency of serving cell handover of the mobile phone within a set time interval nearest to the current time, for example, the location information module 115 or the sensing unit 140 in fig. 1. When the mobile phone is in a high-speed moving process for communication, on the basis of the existing communication state protocol, a Flag bit Flag is added and set to be 1, which indicates that the mobile phone is in a high-speed moving process for communication; when the mobile phone is at low speed or hardly moving, the Flag will take 0.

The control module 204 is configured to control the second processing module 202 to obtain channel information of a current serving cell and/or an adjacent cell of the mobile terminal when the message sent by the determining module is received and the first subscriber identity module 208 is in a call state.

It should be understood that the above subscriber identity card is not limited to the SIM card, USIM card, etc., and the SIM card is used for the explanation in this embodiment.

Specifically, the control module executes corresponding operations according to the values of the flag bits. When the Flag is 1, the control module adjusts the frequency of measuring the channel information of the current serving cell and the neighboring cell. On the basis of the existing mobile terminal call state protocol, a timer is added, and the time interval T1 of the timer can be set according to the mobile phone moving speed or the switching frequency of the serving cell within a set time nearest to the current time, if the mobile phone moving speed is fast or the cell switching frequency is fast, the time period T1 can be set to be a small value, otherwise, a large value can be set. When the mobile phone has two SIM cards, the idle time slot of the auxiliary card is used for measuring the channel information of the calling card service cell and the adjacent cell. This design, in turn, increases the frequency of cell information measurements. Meanwhile, the mobile phone integrates the channel measurement information of the serving cell and the neighboring cell measured by the main card and the auxiliary card (or cards), and actively reports the final result to the base station. The method for measuring cell channel information in the above embodiments is also applicable to the method for measuring cell information by the secondary card and the primary card.

A handover module 205, configured to perform cell handover according to the signal strength of the current cell and/or the neighboring cell.

Specifically, within a period of time T1, if the signal of the current cell is lower than or equal to a certain threshold and the signal strength of the neighboring cell is higher than or equal to a certain threshold, the mobile phone actively informs the base station of the measurement information and requests for handover, and the base station makes a decision according to the reported measurement information and the channel idle state of the target cell, so that the mobile phone can be handed over to the cell with a better signal more smoothly. When the mobile phone has two SIM cards, the information of the cell measured by the main card and the auxiliary card can be combined, and the information is actively reported to the base station according to the comprehensive measurement result to judge whether to switch the cell.

The association module 206 is configured to establish an association relationship between a first subscriber identity module card and a second subscriber identity module card of the mobile terminal, and send cell channel information obtained by the second processing module to the first processing module.

Specifically, the first subscriber identity module card and the second subscriber identity module card may be SIM cards of the same network type, or may be SIM cards of different network types, for example, the first subscriber identity module card is a telecommunication card, and the second subscriber identity module card is a mobile card; the server corresponding to the communication of the first subscriber identity card is a telecommunication network server (i.e. a first network server), and the server corresponding to the communication of the second subscriber identity card is a mobile server (i.e. a second network server).

An embodiment of associating two subscriber identity cards is provided below, and in an embodiment, the card insertion state of the mobile phone card slot can be detected. When the SIM cards are detected to be inserted into the two card slots, the card information of the main card and the card information of the auxiliary card are obtained, and the one-to-one correspondence relationship between the card information of the main card and the card information of the auxiliary card is established and stored in the local mobile phone to establish the binding relationship. And respectively sending the card information of the main card, the card information of the auxiliary card and the binding relationship to a first network server corresponding to the main card and a second network server corresponding to the auxiliary card. Specifically, the registration signaling may be sent to the corresponding server, where the form of the registration signaling is shown in fig. 7, and includes three fields: the network card comprises a Bind flag, Local card info and Bind card info, wherein the Bind flag indicates whether a binding information identification bit exists, the Local card info indicates the card information of the network card, and the Bind card info indicates the card information of the binding card.

For example, in the registration signaling sent to the first network server through the primary card, the Bind flag is an identifier with binding information, the Local card info is card information of the primary card, and the Bind card info is card information of the secondary card.

Referring to fig. 8, an embodiment of a mobile terminal communication method is presented, the method comprising the steps of:

s101, judging whether the moving state of the mobile terminal meets a preset condition or not.

Specifically, the mobile terminal provided in this embodiment is mainly applied to call processing, and is used for processing a call process. It can be understood that the mobile terminal may be a terminal device equipped with a phone card, and in the following embodiments, a mobile phone is taken as an example for detailed description.

Specifically, when the mobile phone is in a call state, whether the mobile phone is in a call in the high-speed moving process is determined according to conditions such as GPS information of the mobile phone, information of a corresponding base station, or the number of times that the mobile phone switches a serving cell within a set time interval nearest to the current time. Such as the location information module 115 or the sensing unit 140 of fig. 1 described above.

And S102, when the moving state of the mobile terminal meets a preset condition, adjusting the control parameter.

Specifically, when the mobile phone is in a high-speed moving process for communication, on the basis of the existing communication state protocol, a Flag is added and set to be 1, which indicates that the mobile phone is in a high-speed moving process for communication; when the mobile phone is at low speed or hardly moving, the Flag will take 0.

And the mobile terminal executes corresponding operation according to the value of the zone bit. When the Flag is 1, the control module adjusts the frequency of measuring the channel information of the current serving cell and the neighboring cell. On the basis of the existing mobile terminal call state protocol, a timer is added, and the time interval T1 of the timer can be set according to the mobile phone moving speed or the switching frequency of the serving cell within a set time nearest to the current time, if the mobile phone moving speed is fast or the cell switching frequency is fast, the time period T1 can be set to be a small value, otherwise, a large value can be set. The frequency controlling the measurement cell may be configured in an uplink frame structure, see fig. 4 (b).

S103, cell switching is carried out according to the signal intensity of the current cell and/or the adjacent cell.

Specifically, in a period of time T1, if the signal of the current cell is lower than or equal to a certain threshold and the signal strength of the neighboring cell is higher than or equal to a certain threshold, the mobile phone actively informs the base station of the measurement information and requests for handover, and the base station makes a decision according to the reported measurement information and the channel idle state of the target cell, so that the mobile phone can be handed over to the cell with a better signal more smoothly.

Referring to fig. 9, another embodiment of a mobile terminal communication method is presented, the method comprising the steps of:

s201, judging whether the moving state of the mobile terminal meets a preset condition.

Specifically, when the mobile phone is in a call state, whether the mobile phone is in a call in the high-speed moving process is determined according to conditions such as GPS information of the mobile phone, information of a corresponding base station, or the number of times that the mobile phone switches a serving cell within a set time interval nearest to the current time.

S202, when the mobile state of the mobile terminal meets the preset condition, adjusting the control parameter.

And the mobile terminal executes corresponding operation according to the value of the zone bit. When the Flag is 1, the control module adjusts the frequency of measuring the channel information of the current serving cell and the neighboring cell. On the basis of the existing mobile terminal call state protocol, a timer is added, and the time interval T1 of the timer can be set according to the mobile phone moving speed or the switching frequency of the serving cell within a set time nearest to the current time, if the mobile phone moving speed is fast or the cell switching frequency is fast, the time period T1 can be set to be a small value, otherwise, a large value can be set. The frequency controlling the measurement cell may be configured in an uplink frame structure, see fig. 4(a) and 4 (b). For example, information of the scell channel is configured in the uplink subframe 3 of the radio frame, in the prior art, only M (M < N) radio frames are information of the scell channel configured in N radio frames transmitted for measurement, while in this embodiment, to increase the frequency of the scell channel, the structure of the transmitted N radio frames is adjusted, as shown in fig. 4(b), each of the N radio frames includes a subframe configured with the scell channel information.

S203, judging the state of the user identification card of the mobile terminal.

Specifically, when the first user card is in a call state and the second user card is in an idle state, step S204 is executed.

And S204, the second user identification card measures the channel information of the current service cell and/or the adjacent cell of the mobile terminal.

The sensing processing chip 417 is used to determine a moving state of the mobile terminal, such as determining whether the current mobile terminal is in a call state and is in a high-speed moving state, in which the mobile terminal needs to frequently switch a serving cell. Whether the mobile terminal is in a call state can be determined according to the subscriber identity card 303 and the corresponding protocol stack 307.

Both protocol stacks (the first protocol stack 411 and the second protocol stack 412) in the implementation of the present invention are configured and controlled by a driver of the first processor 401.

After the user equipment is powered on, the user equipment and the subscriber identity card are communicated once in 28 seconds, and some fixed communication check (such as whether the subscriber identity card is in place and the like) is completed.
