[0025] The embodiments of the present application provide a method, apparatus and storage medium for a terminal device to reside in a cell, which can select a cell of a corresponding frequency band for residence based on signal quality and power consumption in a preset scenario, thereby meeting the communication quality requirements and saving the power consumption of the terminal device to a certain extent.

[0026] In order to make the technical personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, they should all fall within the scope of protection of the present application.

[0027] The following is a brief description of some terms involved in this application, as follows:

[0028] Wideband Code Division Multiple Access (WCDMA) is a 3G cellular network that uses some of the same protocols as the 2G Global System for Mobile Communications (GSM) standard. Specifically, W-CDMA is a wideband spread spectrum 3G mobile communication air interface that uses code division multiple access multiplexing (or CDMA general multiplexing technology, not the CDMA standard).

[0029] Public Land Mobile Network (PLMN) is a network established and operated by the government or an operator approved by it to provide land mobile communication services to the public. This network is usually interconnected with the Public Switched Telephone Network (PSTN) to form a communication network for the entire region or country. For a specific terminal, it is usually necessary to maintain several different types of PLMN lists, and each list will have multiple PLMNs.

[0030] (1) RPLMN (Registered PLMN): Registered PLMN. It is the PLMN that the terminal registered before it was last turned off or disconnected from the network. At the 3GPP TSG TP-21 meeting in 2003, it was decided to delete this parameter from the USIM (Universal Subscriber Identity Module) card and save it in the terminal's memory.

[0031] (2) EPLMN (Equivalent PLMN): a PLMN that is equal to the PLMN currently selected by the terminal and has the same priority.

[0032] (3) EHPLMN (Equivalent Home PLMN): A home PLMN that is equal to the PLMN currently selected by the terminal. In fact, EHPLMN and EPLMN are like China Mobile's newly built 158 ​​network, while PLMN is like the original 135-139 networks.

[0033] (4) HPLMN (Home PLMN): The PLMN to which the terminal user belongs. In other words, the MCC (Mobile Country Code) and MNC (Mobile Network Code) contained in the IMSI (International Mobile Subscriber Identity) number on the terminal USIM card are consistent with the MCC and MNC on the HPLMN. For a certain user, there is only one PLMN to which he belongs.

[0034] (5) VPLMN (Visited PLMN): The PLMN visited by the terminal user. Its PLMN is not identical to the MCC and MNC of the IMSI stored in the SIM card. When the mobile terminal loses coverage, a VPLMN will be selected.

[0035] (6) UPLMN (User Controlled PLMN): is a parameter related to PLMN selection and stored on the USIM card.

[0036] (7) OPLMN (Operator Controlled PLMN): is a parameter related to PLMN selection and stored on the USIM card.

[0037] (8) FPLMN (Forbidden PLMN): a PLMN that is prohibited from access. Usually, when a terminal attempts to access a PLMN and is rejected, it will add the PLMN to this list.

[0038] (9) APLMN (Approve PLMN): A PLMN on which the terminal can find at least one cell and read its PLMN identification information.

[0039] The mobility management of terminal devices, in 3GPP (3rd Generation Partnership Project), mainly regulates the reselection specifications of terminal devices in idle state and the measurement configuration of network devices in connected state. The terminal devices report measurement reports, and the network devices schedule the terminal devices based on the measurement reports. The core principle is to maintain the best performance service cell, which can relatively obtain the best communication quality.

[0040] The connected state means that connections have been established between the terminal device and the base station, and between the base station and the core network for the target terminal device (such as a mobile phone), and data transmission can be performed at any time. This state does not require establishment delay, so the delay is the shortest.

[0041] The deactivated state means that there is no connection between the terminal device and the base station, but a connection is established between the base station and the core network for the terminal device. Once there is data to be sent to the terminal device, the base station will send a paging message, and the terminal device will quickly establish a connection with the base station after receiving it, and the terminal device will change from the deactivated state to the connected state.

[0042] The idle state means that no connection is established between the terminal device and the base station, or between the base station and the core network. If there is data to be sent to the terminal device, or the terminal device needs to send data, it will take a certain delay to switch from the idle state to the connected state.

[0043] Problems with existing technical solutions: unified specifications are made for the performance dimension with signal quality as the core, but other hardware support of the terminal device itself and its impact on the power consumption of the terminal device are not clearly considered, and the importance of standby time caused by power consumption factors in the NR 5G era is not considered. The impact of bandwidth differences under different frequency bands in the existing network is also not considered (it is generally believed that bandwidth size is proportional to power consumption). That is, the existing technology only defines the performance specifications of terminal devices searching the network, and does not consider other impacts of the power consumption dimension.

[0044] In the technical solution of the present application, in the scenario specifications not clearly defined by 3GPP, under different requirements of performance and power consumption, when the terminal device is in the first motion state or the second motion state, the current resident frequency band of the terminal device is intelligently reselected or switched to a cell for resident in combination with different preset scenarios to make up for the insufficient coverage of its power consumption factor and improve the user experience.

[0045] Among them, the terminal device speed in the first motion state is less than the speed threshold (which may include a stationary state or a micro-motion state), and the terminal device speed in the second motion state is greater than or equal to the speed threshold (which may be called a mobile state).

[0046] like Figure 1 As shown, it is a system architecture diagram of the communication system used in the embodiment of the present application. The communication system may include a terminal device and a network device, and the network device may be a device that communicates with the terminal device (or referred to as a communication terminal, terminal). The network device can provide communication coverage for a specific geographical area and can communicate with the terminal devices located in the coverage area. Figure 1 One network device and two terminal devices are shown exemplarily. Optionally, the communication system may include multiple network devices and each network device may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application. Optionally, the communication system may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0047] Among them, the network equipment may include access network equipment and core network equipment. That is, the wireless communication system also includes multiple core networks for communicating with the access network equipment. The access network equipment may be an evolutionary base station (evolutional node B, referred to as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), micro-micro base station, access point (AP), transmission point (TP) or new generation base station (new generation Node B, gNodeB) in a long-term evolution (LTE) system, a next-generation (mobile communication system) (next radio, NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

[0048] In the embodiment of the present application, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0049] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0050] The technical solution of the present application is further described below by way of embodiments. Figure 2 As shown, it is a schematic diagram of an embodiment of a method for a terminal device to camp on a cell in an embodiment of the present application, which may include:

[0051] 201. Detect whether the terminal device meets a preset state.

[0052] The preset state may include:

[0053] is in at least one of a first motion state and a screen-off state; or,

[0054] It is in at least one of the second motion state and the screen-on state, and the current data traffic is less than the data traffic threshold; the terminal device rate in the first motion state is less than the rate threshold, and the terminal device rate in the second motion state is greater than or equal to the rate threshold.

[0055] Exemplarily, the motion sensor in the terminal device can be used to identify whether the current motion state of the terminal device is the first motion state or the second motion state. That is, the motion state can be identified by a preset algorithm of the motion sensor. Optionally, an identification cycle can be configured. When the identified motion state is in the first motion state, the motion state can be periodically identified through the identification cycle; when the identified motion state is in the second motion state, the motion state can be identified in real time.

[0056] When the terminal device is in the first motion state, it indicates that the current serving cell and neighboring cell of the terminal device are stable in the current network environment, and the cell obtained by the cell measurement is approximately stable with little fluctuation. When the terminal device is in the second motion state, it indicates that the current serving cell and neighboring cell of the terminal device are not stable in the current network environment.

[0057] It is understandable that the screen-on / off state can indicate whether the current scene is perceived by the user. If the terminal device is in the screen-off state, it means that the scene cannot be directly perceived by the user. At this time, the performance is less concerned and the scene is safe, so the power consumption can be considered as the main consideration.

[0058] For the determination of data traffic, the terminal device can monitor the data traffic (data) in real time to determine whether it reaches a certain defined threshold (e.g., 2 m / s) to determine in real time whether the current data traffic exceeds the data traffic threshold or does not exceed the data traffic threshold. It is also possible to determine whether the current data traffic exceeds the data traffic threshold by using a preset application list (the preset application list is a list of applications with high frequency and low data traffic). For example, if the currently running application (app) is in the preset application list, it can be considered that the current data traffic is less than the data traffic threshold.

[0059] It should be noted that step 201 is an optional step.

[0060] 202. When it is detected that the terminal device meets a preset state, reselect or switch to a target neighboring cell for residence.

[0061] The signal quality of the target neighboring cell is greater than or equal to a signal quality threshold, and the power consumption of the target neighboring cell is less than the current serving cell where the terminal device resides.

[0062] Optionally, the signal quality indicator may include at least one of a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indicator (RSSI), and a signal-to-interference plus noise ratio (SINR). Among them, the SINR may include a reference signal-to-noise ratio (RS-SINR).

[0063] The RF hardware design of the terminal device in this application has different power consumption in different bands, as shown below:

[0064] 1. The power consumption of PA (Power Amplifier) ​​is mainly related to the power size.

[0065] like Figure 3A FIG. 1 is a schematic diagram of the power consumption of n1 and n78 at different powers in the embodiment of the present application. Figure 3A In the figure, the horizontal axis is bandwidth and the vertical axis is power consumption. Under the same power, the power consumption of n1 is much greater than that of n78. Therefore, the power consumption of frequency division duplexing (FDD) band is greater than that of time division duplexing (TDD) band.

[0066] 2. The power consumption between different TDD bands and FDD bands is also different.

[0067] like Figure 3B , which is a schematic diagram of frequency band and power consumption, and standard and power consumption in the embodiment of the present application. Figure 3B As shown in the figure, in the frequency band and power consumption, the horizontal axis is power and the vertical axis is power consumption; in the standard and power consumption, the horizontal axis is power and the vertical axis is power consumption. Among them, the standard, frequency band, FDD / TDD, power, etc. will affect the power consumption of the transceiver.

[0068] For example: the power consumption of each 4G frequency band is different, and the power consumption of each NR 5G frequency band is also different; FDD power consumption is greater than TDD power consumption; in the case of the same frequency and the same channel, if the power consumption is different for different standards, NR power consumption > LTE power consumption; the PA power of the terminal device will also affect the power consumption, the greater the power, the greater the power consumption.

[0069] 3. Under the same band, the larger the bandwidth, the greater the power consumption.

[0070] like Figure 3C , which is a schematic diagram of bandwidth and power consumption in the n1 and n8 frequency bands in the embodiment of the present application. Figure 3C In the figure, the horizontal axis is bandwidth and the vertical axis is power consumption. The larger the bandwidth, the greater the power consumption.

[0071] Through 1 and 2, we can finally get a table of the power consumption of the current RF and hardware devices of the terminal device in each band. The power consumption of different bands is different, for example, the experimental data in Table 1 below:

[0072] Table 1 Power consumption of different bands corresponding to different powers

[0073]

[0074] Based on this table, a priority table of band power consumption is customized, that is, the band list is obtained from the smallest to the largest power consumption, as shown in Table 2 below:

[0075] Table 2: Priority table of different bands from small to large in terms of power consumption

[0076]

[0077] It should be noted that in Table 1 and Table 2, when there is no uplink data, the power can be considered to be 0. The power involved in this application refers to the power of the power amplifier in the terminal device.

[0078] Optionally, when it is detected that the terminal device meets a preset state, reselecting or switching to a target neighboring cell for residence may include but is not limited to the following implementations:

[0079] (1) When detecting that the terminal device is in the first motion state, the screen-off state, and the idle state, reselecting to reside in a first target neighboring cell, the signal quality of the first target neighboring cell is greater than or equal to a signal quality threshold, and the corresponding frequency band power consumption is minimal.

[0080] Exemplarily, when the terminal device is in the first motion state + screen-off state, if the terminal device is in the NR or LTE idle state, based on the specification conditions of 38.304 / 36.304, reselect to the first target neighboring cell for residence, and the first target neighboring cell is a cell on the frequency band (band) with a signal quality greater than or equal to the signal quality threshold and the lowest power consumption. For example, reselect to the cell on the LTE B40 (i.e., 4G TDD B40) band in Table 2 above for residence.

[0081] It should be noted that the 3GPP specifications must be met first. If there are multiple adjacent cells and the signal quality of the adjacent cells meets the preset signal threshold (for example, RSRP>=-105, RSRQ>=-10, SINR>=0), the cell on the band with the lowest power consumption can be reselected for residence.

[0082] For example: Current serving cell A NR Band 1 RSRP = -100

[0083] Current neighboring cell B NR Band 40 RSRP = -105

[0084] According to the 3GPP specifications, the terminal device will preferentially reside in the current serving cell A. After the optimization of this application, when the terminal device is in the first motion state + screen-off state, and in the idle state, it will reselect to reside in the current adjacent cell B based on the power consumption factors of the band.

[0085] (2) When detecting that the terminal device is in the first motion state, the screen-off state, and the connected state, adjust the measurement report of the terminal device, and report the adjusted measurement report to the network device, so that the network device switches the current service cell where the terminal device resides to the second target neighboring cell, the adjusted measurement report includes the reported signal quality of the current service cell and the reported signal quality of the second target neighboring cell, the power consumption of the second target neighboring cell is less than the power consumption of the current service cell, the actual signal quality of the second target neighboring cell is less than the actual signal quality of the current service cell, and the actual signal quality of the second target neighboring cell is greater than or equal to the signal quality threshold.

[0086] Optionally, the reported signal quality of the current serving cell in the measurement report is lower than the actual signal quality of the current serving cell, and / or the reported signal quality of the second target neighboring cell is higher than the actual signal quality of the second target neighboring cell.

[0087] Optionally, when it is detected that the terminal device is in the first motion state, the screen-off state, and the connected state, adjusting the measurement report of the terminal device and reporting the adjusted measurement report to the network device may include: when it is detected that the terminal device is in the first motion state, the screen-off state, and the connected state, reducing the actual signal quality of the current service cell by a first preset deviation to obtain the reported signal quality of the current service cell, and / or increasing the actual signal quality of the second target neighboring cell by a second preset deviation to obtain the reported signal quality of the second target neighboring cell; reporting the reported signal quality of the current service cell and / or the reported signal quality of the second target neighboring cell as the adjusted measurement report to the network device. That is, when adjusting the measurement report, the terminal device can either reduce the signal quality of the current service cell alone, increase the service quality of the neighboring cell alone, or reduce the signal quality of the current service cell and increase the service quality of the neighboring cell. The specific embodiments of the present application are not limited thereto.

[0088] Optionally, the first preset deviation and the second preset deviation may be the same or different, and this application does not make any specific limitation.

[0089] Exemplarily, when the terminal device is in the first motion state + screen-off state, if the terminal device is in the NR or LTE idle state, the measurement report can be adjusted to make it easier for the network device to switch the terminal device to a cell on a band with low power consumption for residence, that is, the network device switches the terminal device from the current service cell to the second target neighboring cell for residence, wherein the power consumption of the second target neighboring cell is less than the power consumption of the current service cell, and the actual signal quality of the second target neighboring cell is less than the actual signal quality of the current service cell, and is greater than or equal to the signal quality threshold.

[0090] For example: Current serving cell ANR Band 1 RSRP = -100

[0091] Current neighboring cell B NR Band 40 RSRP = -105

[0092] According to the 3GPP specifications, the terminal device will preferentially reside in cell A. After the optimization of this application, when the terminal device is in the first motion state + screen-off state, and in the connected state, based on the power consumption factor of the band, when the network device configures the event of measuring cell B, the terminal device will report that the signal quality of the current serving cell A is too low by one or more offsets, and / or, report that the signal quality of the current adjacent cell B is too high by one or more offsets, thereby causing the network device to be more inclined to switch the terminal device from the current serving cell A to reside in the current adjacent cell B.

[0093] (3) When it is detected that the terminal device is in at least one of the second motion state and the screen-on state, and the current data traffic of the terminal device is less than the data traffic threshold, reselect a third target neighboring cell for residence, and the signal quality of the third target neighboring cell is greater than or equal to the signal quality threshold, and the corresponding frequency band power consumption is minimized.

[0094] Optionally, when it is detected that the terminal device is in at least one of the second motion state and the screen-on state, and the current data traffic of the terminal device is less than a data traffic threshold, reselecting to reside in a third target neighboring cell may include: when it is detected that the terminal device is in at least one of the second motion state and the screen-on state, and the currently running application is in a preset application list, reselecting to reside in the third target neighboring cell.

[0095] Exemplarily, when the terminal device is no longer in the first motion state + screen-off state, that is, the terminal device is in at least one of the second motion state and the screen-on state, if real-time detection shows that the current data traffic volume of the terminal device is less than the data traffic volume threshold, or, by determining that the currently running application is in the preset application list, it can be considered that the current data traffic volume is less than the data traffic volume threshold. At this time, the terminal device reselects to the third target neighboring cell for residence.

[0096] For example, the preset application list may include commonly used high-frequency, low-data traffic applications such as WeChat and Alipay.

[0097] Optionally, the method may also include: when it is detected that the terminal device is in at least one of the second motion state and the screen-on state, and the current data traffic of the terminal device is greater than or equal to the data traffic threshold, selecting a fourth target neighboring cell to reside in, the signal quality of the fourth target neighboring cell is greater than or equal to the signal quality threshold, and the bandwidth of the corresponding frequency band is the largest.

[0098] Optionally, when it is detected that the terminal device is in at least one of the second motion state and the screen-on state, and the current data traffic of the terminal device is greater than or equal to the data traffic threshold, selecting the fourth target neighboring cell to reside may include: when it is detected that the terminal device is in at least one of the second motion state and the screen-on state, the current data traffic of the terminal device is greater than or equal to the data traffic threshold, and the public land mobile network of the current service cell is in a preset public land mobile network table, and the bandwidth of the current service cell is less than the bandwidth threshold, if the bandwidth of the current service cell is less than the bandwidth of the fourth target neighboring cell, reducing the signal quality of the current service cell to select the fourth target neighboring cell to reside.

[0099] For example, when the terminal device is in the second motion state, or the screen-on state, or the second motion state + the screen-on state, if the current data traffic of the terminal device is greater than or equal to the data traffic threshold, the performance dimension can be adjusted to be prioritized. The bandwidth of the new resident cell is observed, and on the basis of meeting 3GPP, the cell on the band with a larger bandwidth is always selected, and the cell on the band with a smaller bandwidth is suppressed.

[0100] For example, N8 and N28 are common bands with relatively small bandwidths. If it is on China Telecom (FDD-LTE) (46011) network, N8 bandwidth is 10MHz.

[0101] The software configuration setting table is as follows:

[0102] / / band_preference_list[0]

[0103] {

[0104] {0x04,0x06,0x00,0x00,0x03,0x0F}, / / PLMN[0]

[0105] {0x04,0x06,0x00,0x01,0x01,0x0F}, / / PLMN[1]

[0106] {0x00,0x00,0x00,0x00,0x00,0x00}, / / PLMN[2]

[0107] },

[0108] 0x0008, / / Band8

[0109] 0x000A / / BW-threshold = 10MHz

[0110] 0xFFFC, / / idle_rsrp_offset=-8dbm

[0111] 0xFFFE, / / idle_rsrq_offset=-2db

[0112] 0xFFFC, / / conn_rsrp_offset=-8dbm

[0113] 0xFFFE, / / conn_rsrq_offset=-2db

[0114] },

[0115] Exemplarily, if the PLMN+band of the current serving cell meets the configuration, for example, the PLMN of the current serving cell is in the preset public land mobile network table, and the bandwidth Bandwidth of the current serving cell is less than the bandwidth threshold BW-threshold, or the PLMN+band of the fourth target neighboring cell meets the configuration, for example, the PLMN of the fourth target neighboring cell is in the preset public land mobile network table, and the bandwidth Bandwidth of the fourth target neighboring cell is less than the bandwidth threshold BW-threshold. When performing cell reselection in idle state and measuring and reporting A3 / A5 events in connected state, an offset penalty is imposed on small bandwidth cells.

[0116] It should be noted that if BW-threshold is the default value without additional settings (e.g. 0xFFFF), it is considered that the bandwidth threshold is not checked and the band is directly considered as a small bandwidth; if it is set to a valid array, such as 10MHz, then the band with a bandwidth not greater than 10MHz in the 46011 network is a small bandwidth.

[0117] Optionally, if the current service cell where the terminal device resides is a large bandwidth cell, if the signal quality is less than the signal quality threshold, when reselecting or switching to a small bandwidth cell, it is necessary to increase the deviation of the signal quality of the small bandwidth cell, so that the terminal device is easier to reside in the small bandwidth cell.

[0118] If the current serving cell where the terminal device resides is a small bandwidth cell, and if the signal quality is less than the signal quality threshold, when reselecting or switching to a large bandwidth cell, it is necessary to increase the deviation of the signal quality of the small bandwidth cell to speed up the escape from the small bandwidth cell.

[0119] Exemplarily, idle_rsrp_offset and idle_rsrq_offset refer to the increased deviation when calculating small bandwidth cells between same-frequency and different-frequency cells with the same priority level based on the 3GPP 38304 protocol, which makes it easier to select cells residing in large bandwidth and speed up the escape from cells in small bandwidth.

[0120] conn_rsrp_offset and conn_rsrq_offset are similar. In the NR connected state, based on 3GPP38331, the deviation is increased by adjusting the measurement report for small bandwidth cells, making it easier to maintain cells with large bandwidth and speed up switching to escape from cells with small bandwidth.

[0121] If the current serving cell where the terminal device resides is a large bandwidth cell and the signal quality is less than the signal quality threshold, when reselecting or switching to the large bandwidth cell, normal reselection or switching rules are followed without involving deviation.

[0122] If the current serving cell where the terminal device resides is a small bandwidth cell, and if the signal quality is less than the signal quality threshold, when reselecting or switching to the small bandwidth cell, a deviation is added to the signal quality of the small bandwidth cell (target cell and source cell) at the same time, so it is not affected during reselection or switching.

[0123] In an embodiment of the present application, if the terminal device is in a first motion state + screen-off state, or in a second motion state, and / or a screen-on state, the cell in which the terminal device resides is intelligently selected based on power consumption and performance to enhance the user experience in the power consumption dimension. In the NR SA network, the power consumption benefits are particularly obvious.

[0124] Optionally, the embodiments of the present application are applied to NR SA (Standalone, independent networking) network, LTE network, or higher-standard network scenarios.

[0125] In an embodiment of the present application, when it is detected that the terminal device meets a preset state, reselect or switch to a target neighboring cell for residence; wherein the signal quality of the target neighboring cell is greater than or equal to a signal quality threshold, and the power consumption of the target neighboring cell is less than the current serving cell where the terminal device resides. Because the signal quality of the target neighboring cell is greater than or equal to the signal quality threshold, and the power consumption of the target neighboring cell is less than the current serving cell where the terminal device resides, when it is detected that the terminal device meets the preset state, reselect or switch to the target neighboring cell for residence, which can not only meet the communication quality requirements, but also save the power consumption of the terminal device to a certain extent.

[0140] Combine the following Figure 6 A detailed introduction to the various components of the mobile phone in the terminal device:

[0141] The RF circuit 610 can be used for receiving and sending signals during information transmission or calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 680 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 610 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (Low Noise Amplifier, LNA), a duplexer, etc. In addition, the RF circuit 610 can also communicate with the network and other devices through wireless communication. The above wireless communication can use any communication standard or protocol, including but not limited to Global System of Mobile communication (Global System of Mobile communication, GSM), General Packet Radio Service (General Packet Radio Service, GPRS), Code Division Multiple Access (Code Division Multiple Access, CDMA), Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA), Long Term Evolution (Long Term Evolution, LTE), email, Short Messaging Service (SMS), etc.

[0142] The memory 620 can be used to store software programs and modules. The processor 680 executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory 620. The memory 620 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 620 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0143] The input unit 630 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile phone. Specifically, the input unit 630 may include a touch panel 631 and other input devices 632. The touch panel 631, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 631 or near the touch panel 631 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. Optionally, the touch panel 631 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 680, and can receive and execute commands sent by the processor 680. In addition, the touch panel 631 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 631, the input unit 630 may also include other input devices 632. Specifically, the other input devices 632 may include but are not limited to one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, etc.

[0144] The display unit 640 can be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 640 may include a display panel 641. Optionally, the display panel 641 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch panel 631 may cover the display panel 641. When the touch panel 631 detects a touch operation on or near it, it is transmitted to the processor 680 to determine the type of touch event. Subsequently, the processor 680 provides a corresponding visual output on the display panel 641 according to the type of touch event. Although in Figure 6 In the embodiment, the touch panel 631 and the display panel 641 are used as two independent components to realize the input and output functions of the mobile phone, but in some embodiments, the touch panel 631 and the display panel 641 can be integrated to realize the input and output functions of the mobile phone.

[0145] The mobile phone may also include at least one sensor 650, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 641 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 641 and / or the backlight when the mobile phone is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0146] The audio circuit 660, the speaker 661, and the microphone 662 can provide an audio interface between the user and the mobile phone. The audio circuit 660 can transmit the received audio data to the speaker 661 after converting the received audio data into an electrical signal, which is converted into a sound signal for output; on the other hand, the microphone 662 converts the collected sound signal into an electrical signal, which is received by the audio circuit 660 and converted into audio data, and then the audio data is output to the processor 680 for processing, and then sent to another mobile phone through the RF circuit 610, or the audio data is output to the memory 620 for further processing.

[0147] Wi-Fi is a short-range wireless transmission technology. The mobile phone can help users send and receive emails, browse web pages and access streaming media through the Wi-Fi module 670, which provides users with wireless broadband Internet access. Figure 6 A Wi-Fi module 670 is shown, but it is understandable that it is not an essential component of the mobile phone and can be omitted as needed without changing the essence of the invention.

[0148] The processor 680 is the control center of the mobile phone. It uses various interfaces and lines to connect various parts of the entire mobile phone. By running or executing software programs and / or modules stored in the memory 620, and calling data stored in the memory 620, it executes various functions of the mobile phone and processes data, thereby monitoring the mobile phone as a whole. Optionally, the processor 680 may include one or more processing units; preferably, the processor 680 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications.
