[0113] refer to Figure 1 , Figure 1 A schematic flow chart of a cell changing method is provided, which is executed by a first device, and the method includes:

[0114] S101: Determine, according to abnormal cell information, whether a first cell currently connected by the first device has been recorded as an abnormal cell;

[0115] S102: When the first cell has been recorded as an abnormal cell, control the first device to change the cell.

[0116] Exemplarily, the first device mentioned above may be a portable electronic device capable of connecting to a mobile network, such as a mobile phone, a tablet computer, a laptop computer, and a phone watch.

[0117] The cell in the embodiment of the present application refers to an area covered by a radiation signal of a base station or a part of a base station in a cellular mobile communication system. For example, the cell may include but is not limited to a sector. In this area, a mobile station can reliably communicate with the base station through a wireless channel.

[0118] In some embodiments, abnormal cell information may be understood as information about abnormal cells. The information may include, but is not limited to: cell information and / or abnormal information.

[0119] In some embodiments, the abnormal cell information may be understood as: information about a cell having good signal quality but poor communication service.

[0120] The cell information may include but is limited to at least one of the following:

[0121] Cell ID;

[0122] Cell location information;

[0123] Cell type information.

[0124] The abnormal information may include but is not limited to at least one of the following:

[0125] Time period information when the cell is abnormal;

[0126] Frequency information of abnormalities in the cell;

[0127] Abnormal type information of the cell, etc.

[0128] Exemplarily, the above-mentioned abnormal cell may be a cell with abnormal signals, for example, a cell with normal RSRP and RSRQ but abnormal signal to interference plus noise ratio (SINR), or a cell with abnormal RSRP, RSRQ and SINR.

[0129] The above abnormal cell information refers to cells with abnormal signals that have been recorded in history.

[0130] Exemplarily, in historical time, each time the first device is connected to a cell, the terminal will determine the RSRP, RSRQ and / or SINR of the cell. If it is found that after the terminal accesses the cell, the cell cannot provide normal communication services, or the RSRP, RSRQ and / or SINR of the cell, the cell is determined to be an abnormal cell, and the cell is recorded as an abnormal cell. Recording the cell as an abnormal cell here can be understood as: recording the cell information of the cell. As another example, the cell information is added to the cell abnormality list, etc. The cell information may include but is not limited to the cell identifier. In some embodiments, the cell information may also include: cell location information, etc.

[0131] Based on this, the first device may store cell information of multiple abnormal cells, that is, the abnormal cell information mentioned above. When the first device is connected to the first cell, it may determine whether the first cell has been previously recorded as an abnormal cell based on the previously stored abnormal cell information. When it is determined that the first cell has been recorded as an abnormal cell, it means that the signal of the first cell has been abnormal at a historical time. In order not to affect the user's Internet speed and call quality, when it is determined that the first cell has been recorded as an abnormal cell at a historical time, the first device may be controlled to perform a cell change operation to reduce the impact of the abnormal signal of the current cell on the user's use of the first device.

[0132] In some embodiments, controlling the first device to perform a cell change operation includes but is not limited to at least one of the following:

[0133] Measuring neighboring cells and finding a second cell with a better SINR than the first cell;

[0134] Switch to the second cell;

[0135] Reselect to the second cell.

[0136] If the first cell is not recorded as an abnormal cell, the electronic device may be controlled to continue to be connected to the first cell.

[0137] Exemplarily, the second cell may be a cell adjacent to the first cell, or another cell close to the first cell. The second cell may be a same-frequency cell, a different-frequency cell, and / or a different-system cell of the first cell.

[0138] In an embodiment, the abnormal cell information may further include time information of each cell being recorded as an abnormal cell, and when it is determined that the first cell is recorded as an abnormal cell based on the abnormal cell information, the time information of the first cell being recorded as an abnormal cell is obtained;

[0139] When the time interval between the moment when the first cell is recorded as an abnormal cell and the current moment is less than the second preset time interval, it means that the time when the first cell signal became abnormal is close to the current moment, and the possibility of returning to normal is small. At this time, the first device can be controlled to directly perform related operations to connect to the second device.

[0140] When the time interval between the moment when the first cell is recorded as an abnormal cell and the current moment is greater than or equal to the second preset time interval, it means that the time when the signal of the first cell was abnormal was relatively long from the current moment, and it is possible that it has returned to normal. At this time, the RSRP, RSRQ and SINR values ​​of the first cell at the current moment can be obtained, and based on RSRP, RSRQ and SINR, it can be determined whether the signal of the first cell has returned to normal, and when it is determined that the signal of the first cell is still abnormal, the first device is controlled to change the cell. When it is determined that the signal of the first cell has returned to normal, continue to stay in the first cell.

[0141] The second preset time interval mentioned above can be set as needed, for example, any value within 2 hours.

[0142] In an embodiment of the present application, the possibility of the signal of the first cell returning to normal at the current moment can be determined based on the moment when the first cell is recorded as an abnormal cell. When it is determined based on the moment when the first cell is recorded as an abnormal cell that the possibility of the signal of the first cell returning to normal at the current moment is small, the first device can be controlled to change the cell, thereby improving the cell replacement efficiency of the first device.

[0143] In one embodiment, the abnormal cell information also includes the number of times each cell is recorded as an abnormal cell. When the first cell is recorded as an abnormal cell, the number of times the first cell is recorded as an abnormal cell in historical time is obtained. When it is determined that the number of times the first cell is recorded as an abnormal cell in historical time is greater than or equal to a preset number of times, it means that the signal of the first cell is often abnormal in historical time, and the possibility of recovering to normal is small at present. At this time, the first device can be controlled to change the cell.

[0144] When it is determined that the number of times the first cell is recorded as an abnormal cell in the historical time is less than the preset number, it means that the abnormality of the signal of the first cell is accidental and may have been restored to normal at present. At this time, the RSRP, RSRQ and SINR of the first cell at the current moment can be obtained, and based on the RSRP, RSRQ and SINR, it can be determined whether the signal of the first cell has been restored to normal, and when it is determined that the signal of the first cell is still abnormal, the first device is controlled to change the cell. When it is determined that the signal of the first cell has been restored to normal, the device continues to stay in the first cell.

[0145] The above-mentioned preset number of times can be set as needed, for example, any number between 3-5 times.

[0146] In the embodiment of the present application, when the first device determines whether the currently connected first cell has been recorded as an abnormal cell based on the abnormal cell information, if the first cell has been recorded as an abnormal cell, since the abnormal cell record indicates that the cell has a signal abnormality in the historical time, when it is determined that the first cell has been recorded as an abnormal cell, the first device is controlled to change the cell so that the first device can connect to other cells, reducing the impact of the signal abnormality of the first cell on Internet access fluency and call quality, thereby improving user experience.

[0147] refer to Figure 2 In one embodiment, the S102 includes:

[0148] S201: When the first cell has been recorded as an abnormal cell, determining whether the first cell is in a preset state;

[0149] S202: If the first cell is in a preset state, control the first device to change the cell.

[0150] Exemplarily, when it is determined according to the abnormal cell information that the first cell has been recorded as abnormal cell information, the time when the first cell is recorded as an abnormal cell is obtained. When the time interval between the time when the first cell is recorded as an abnormal cell and the current time is greater than the second preset time interval, it means that the first cell was recorded as an abnormal cell a long time ago, and the current signal may have returned to normal.

[0151] At this time, it can be determined whether the signal of the first cell is still abnormal according to whether the first cell is in the preset state. When it is determined that the first cell is in the preset state, it means that the first cell is still an abnormal cell, and the first device is controlled to change the cell. When the first cell is not in the preset state, it means that the signal of the first cell has returned to normal. At this time, the first device can be controlled to continue to stay in the first cell.

[0152] In an embodiment of the present application, when it is determined that the time interval between the latest time when the first cell is recorded as an abnormal cell and the current time is long, it is possible to further determine whether the first cell has returned to normal by determining whether the first cell is in a preset state. This can reduce the inconvenience caused to the user by the first device still performing a cell change operation when the first cell has returned to normal.

[0153] Exemplarily, when it is determined according to the abnormal cell information that the first cell has been recorded as abnormal cell information, the number of times the first cell is recorded as an abnormal cell is obtained. When the number of times the first cell is recorded as an abnormal cell is less than a preset number, it indicates that the abnormality of the first cell is an accidental event and may have returned to normal.

[0154] Therefore, it is possible to further determine whether the signal of the first cell has returned to normal based on whether the first cell is in a preset state. When it is determined that the first cell is in a preset state, it means that the signal of the first cell is still abnormal, that is, the first cell is still an abnormal cell. At this time, in order not to affect the network speed and call quality of the first device, the first device is controlled to change cells. When the first cell is not in the preset state, it means that the signal of the first cell has returned to normal. At this time, the first device can be controlled to continue to stay in the first cell.

[0155] The above-mentioned preset state is a signal abnormal state.

[0156] Exemplarily, the RSRP and RSRQ may be normal, but the SINR may be abnormal. That is, when it is determined that the RSRP and RSRQ of the first area are normal, but the SINR is abnormal, it is determined that the first cell is in a preset state.

[0157] In an embodiment of the present application, when it is determined that the first cell has been recorded as an abnormal cell at a historical time, whether the signal of the first cell has returned to normal is determined based on whether the first cell is currently in a preset state. If the first cell is in the preset state, it means that the signal of the first cell is still abnormal. At this time, the first device can be controlled to connect to the second cell to avoid affecting the network speed and call quality of the first device. If the first cell is not currently in the preset state, it means that the signal of the first cell has returned to normal. At this time, there is no need to change the cell, reducing the inconvenience caused to the user by the first device performing the cell change process.

[0158] In some embodiments, the terminal may first determine whether the first cell is in a preset state;

[0159] When it is determined that the first cell is in a preset state, it is determined whether the first cell is recorded as an abnormal cell according to the abnormal cell information.

[0160] In some embodiments, the first device may store abnormal cell information locally.

[0161] refer to Figure 3 In another embodiment, the method further comprises:

[0162] S103: Receive the abnormal cell information collected by the second device.

[0163] The second device in the embodiment of the present application may be a physical device or a virtual device with a large storage capacity.

[0164] For example, the second device in the embodiment of the present application may be a server or a cloud service platform.

[0165] In the embodiment of the present application, considering that the number of cells distributed is relatively large, the number of cells that an electronic device can connect to is limited, and the cell information of abnormal cells that can be collected is also limited. Therefore, the process of collecting and storing abnormal cell information can be performed by the second device.

[0166] In some embodiments, the first device may send a request message to the second device, and the request message may include information reflecting the current location of the first device. In this way, the second device can return abnormal cell information related to the current location of the first device to the first device. In this way, the first device can receive abnormal cell information in the area where the first device is located from the second device, rather than abnormal cell information of the entire network, thereby reducing the amount of information interaction between the first device and the second device.

[0167] Exemplarily, when all terminal devices connected to the second device determine that the cell to which they are currently connected is an abnormal cell, they may send cell information to the second device, and the second device may collect and store the abnormal cell information sent by each terminal device.

[0168] Based on this, when the first device needs to determine whether the first cell is an abnormal cell based on the abnormal cell information, it can receive the abnormal cell information sent by the second device, and determine whether the first cell has been recorded as an abnormal cell based on the received abnormal cell information.

[0169] Exemplarily, the abnormal cell information sent by the second device and received by the first device may include the number of times signal abnormalities occur in the abnormal cell and the time when the signal abnormality most recently occurred.

[0170] In another embodiment, when the first device is connected to the first cell, it is also possible to first determine whether the first cell is in a preset state, and when it is determined that the first cell is in the preset state, send a first message to the second device, wherein the first message is used to request to obtain abnormal cell information stored in the second device.

[0171] After receiving the abnormal cell information sent by the second device, if it is determined that the first cell has been recorded as an abnormal cell before, it means that the signal abnormality of the first cell is unlikely to recover in a short period of time. At this time, the first device is controlled to change the cell.

[0172] In an embodiment, the determining whether the first cell is in a preset state includes:

[0173] Acquire current signal parameters of the first cell;

[0174] Based on the current signal parameter, it is determined whether the first cell is in a preset state.

[0175] Exemplarily, the first device may obtain the current signal parameter of the first cell, and compare the obtained current signal parameter with a preset value. If the current signal parameter of the first cell is less than the preset value, it means that the current signal parameter of the first cell is poor, and then it is determined that the first cell is in a preset state. If the current signal parameter of the first cell is greater than or equal to the preset value, it means that the current signal parameter of the first cell is good, and then it is determined that the first cell is not in the preset state.

[0176] Exemplarily, the above-mentioned current signal parameters may include: at least one of RSRP, RSRQ, SINR and carrier signal received strength (Received Signal Strength Indication, RSSI).

[0177] In one embodiment, the current signal parameter includes: SINR, and determining whether the first cell is in a preset state based on the current signal parameter includes:

[0178] When the SINR is less than a first preset value, it is determined that the first cell is in a preset state.

[0179] Exemplarily, when the acquired current signal parameter of the first cell is SINR, a first preset value is acquired, and the current SINR of the first cell is compared with the first preset value.

[0180] If the current SINR of the first cell is less than the first preset value, it is determined that the first cell still has a signal abnormality, that is, the cell is in a preset state. If the SINR of the first cell is greater than or equal to the first preset value, it is determined that the signal of the first cell has returned to normal, and at this time, it is determined that the first cell is not in a preset state.

[0181] The first preset value may be pre-stored in the first device, or may be obtained from the second device when the first device determines that the first cell has been recorded as an abnormal cell according to the abnormal cell information.

[0182] In addition, the second device may also periodically send the first preset value to the first device. Accordingly, the first device receives the first preset value sent by the second device, and updates the first preset value locally stored in the first device based on the received first preset value.

[0183] Among them, the size of the above-mentioned first preset value can be set as needed, and the embodiment of the present application does not limit this.

[0184] Exemplarily, the first preset value mentioned above may be set by the second device according to the device type of the first device.

[0185] For example, when the first device is a tablet computer, it means that the main function of the first device is to surf the Internet. At this time, the second device can configure a first preset value with a larger value for the first device. For example, the first preset value configured for the first device is any value between 20-30db.

[0186] When the first device is a mobile phone, it means that the main function of the first device is to make calls. At this time, the first preset value can be set to a smaller value, for example, any value between 1-10db.

[0187] Exemplarily, the first preset value may also be set by the second device according to the user profile of the user to which the first device belongs. When the user is determined to be young based on the user profile, the first preset value may be set to a larger value, taking into account that young people have a greater need to surf the Internet and have higher requirements for network quality. When the user is determined to be older based on the user profile, the first preset value may be set to a smaller value, taking into account that the elderly generally have weaker needs to surf the Internet than young people.

[0188] Exemplarily, the first preset value configured by the second device for the first device may also be any value between -84qdb and -24qdb, for example, -40dqb.

[0189] In one embodiment, the current signal parameter further includes: reference signal received power RSRP and reference signal received quality RSRQ; when the SINR is less than a first preset value, determining that the first cell is in a preset state includes:

[0190] When the RSRP of the first cell is greater than a first threshold and / or the RSRQ of the first cell is greater than a second threshold, and the SINR of the first cell is less than the first preset value, it is determined that the first cell is in the preset state.

[0191] Exemplarily, the first threshold and the second threshold mentioned above may be minimum values ​​of RSRP and RSRQ when indicating that the signal quality is good.

[0192] For example, the first threshold may be any value between -44dbm and -140dbm. For example, the first threshold may be -90dbm.

[0193] The second threshold mentioned above may be any value between -19.5db and -3db. For example, the second threshold may be -5db.

[0194] In the embodiment of the present application, it is considered that in some cases, even if the RSRP of the first cell is greater than the first threshold and / or the RSRQ is greater than the second threshold, that is, the signal quality of the first cell is excellent, but if the SINR of the first cell is poor at this time, poor call quality or Internet access may still occur. Therefore, when it is determined that the first cell has been recorded as an abnormal cell, the RSRP and RSRQ of the first cell are obtained. If the RSRP of the first cell is greater than the first threshold and / or the RSRQ is greater than the second threshold, the SINR of the first cell can be further obtained. If the SINR is less than the first preset value, it is determined that the first cell is in a preset state, and the first device is controlled to perform a cell change operation.

[0195] If the RSRP of the first cell is less than or equal to the first threshold and the RSRQ is less than or equal to the second threshold, the first device may be directly controlled to perform a cell change operation.

[0196] In an embodiment, determining whether the first cell is in a preset state based on the current signal parameter further includes:

[0197] Receiving a first preset value and a second preset value sent by the second device;

[0198] When the duration that the SINR is less than the first preset value is greater than or equal to a second preset value, it is determined that the first cell is in a preset state.

[0199] Exemplarily, when the first device determines that the first cell has been recorded as an abnormal cell, the first preset value and the second preset value may be acquired from the second device.

[0200] After receiving the first preset value and the second preset value from the second device, the first device can determine whether the SINR of the first cell is less than the first preset value according to the received first preset value. When the SINR of the first cell is less than the first preset value, timing is performed, and the SINR of the first cell is continuously acquired during the timing process. When it is determined that the duration of the SINR of the first cell being less than the first preset value is greater than or equal to the second preset value, it means that the SINR of the first cell is at a relatively small value for a relatively long time, and it also means that the signal of the first cell is still abnormal, which further indicates that the first cell is in a preset state. At this time, the first device is controlled to change the cell.

[0201] If the duration of the SINR of the first cell being less than the first preset value is less than the second preset value, it means that the SINR of the first cell may have a short-term fluctuation and will soon return to normal, with little impact on Internet access speed and call quality. At this time, it can be determined that the first cell is not in the preset state, and the first device is controlled to continue to be connected to the first cell, so as to reduce the inconvenience caused to the user by the frequent cell changes of the first device.

[0202] The second preset value may be set by the second device according to a specific location of the first cell where the first device is currently located.

[0203] Exemplarily, the second device can obtain the specific location of the first cell based on the positioning system in the first device. If it is determined based on the specific location of the first cell that other cells in the area where the first cell is located have also been recorded as abnormal cells, it means that the signal quality in the area where the first cell is located is poor. At this time, if the second preset value is set to a smaller value, it will cause the first device to frequently change cells, and will also affect the user's use of the first device. At this time, the second preset value can be set to a larger value. If the signal quality of other cells in the area where the first cell is located is good, at this time, the second preset value can be set to a smaller value, so that the first device can immediately perform a cell change operation when the signal quality of the first cell does not meet the user's needs, so as to meet the user's requirements for signal quality.

[0204] The positioning system in the first device may be a GPS (Global Positioning System).

[0205] In one embodiment, when the first cell has been recorded as an abnormal cell, controlling the first device to change the cell includes:

[0206] When the first cell has been recorded as an abnormal cell, the cell is connected to the second cell through cell switching or cell reselection.

[0207] Exemplarily, when it is determined based on the abnormal cell information that the first cell has been recorded as an abnormal cell and the first cell is currently in a preset state, an attempt to connect to the second cell may be made by controlling a restart operation of the first device.

[0208] Exemplarily, when the first cell has been recorded as an abnormal cell, the SINR of a second cell adjacent to the first cell may be measured, and if the SINR of the second cell is greater than that of the first cell, the first device may be controlled to switch to the second cell.

[0209] It should be noted that when the first cell to which the first cell is currently connected is an abnormal cell, it is also possible to try to connect to the second cell in other feasible ways, which is not limited in this embodiment of the present application.

[0210] In an embodiment, after the first device is connected to the second cell, the operation of determining whether the second cell is a recorded abnormal cell may continue to be performed.

[0211] Exemplarily, after the first device is connected to the second cell, it can determine whether the second cell has also been recorded as an abnormal cell based on the abnormal cell record, and determine whether the second cell is in a preset state. When it is determined that the second cell has been recorded as an abnormal cell and / or is in a preset state, perform relevant operations to connect to the third cell, and repeat the above judgment process until it is connected to a cell with normal signal.

[0212] Exemplarily, after the first device is connected to the second cell, the SINR of the second cell can be obtained and compared with the third preset value. If the SINR of the second cell is less than the third preset value, it is determined that the second cell is in a preset state.

[0213] The third preset value mentioned above may be greater than the second preset value.

[0214] The method for obtaining the third preset value may refer to the method for obtaining the first preset value and the second preset value described above, and the embodiments of the present application will not be described in detail here.

[0215] In one embodiment, the method further comprises:

[0216] When it is determined that the first cell is in a preset state, the cell information of the first cell is sent to the second device, so that the second device records the first cell as an abnormal cell.

[0217] Exemplarily, considering that the storage capacity of the first device is usually small, if too much abnormal cell information is stored in the first device, it will affect the normal operation of the first device. In addition, since the cells that the first device can connect to are limited, the abnormal cell information that can be collected is also limited. Therefore, the first device can also send the cell information of the first cell to the second device when it is determined that the first cell is in a preset state, so that the second device records the first cell as an abnormal cell.

[0218] Exemplarily, the above-mentioned cell information at least includes:

[0219] The mobile network code of the first cell;

[0220] The mobile country code of the first cell;

[0221] a cell identifier of the first cell;

[0222] The frequency information of the first cell.

[0223] Among them, the Mobile Network Code (Mobile Network Code, MNC) and the Mobile Country Code (Mobile Country Code, MCC) can be used to uniquely identify the operator of the network to which the first device is connected.

[0224] Among them, MCC is used to uniquely identify the country to which the mobile user belongs.

[0225] The above-mentioned cell identifier may be a physical cell identifier (PCI) and / or a Cell ID of a cell.

[0226] The above-mentioned cell information may also include frequency band information of the first cell signal, a tracking area code (Tracking Area Code, TAC), a location area code (Location Area Code, LAC) and specific location information of the first cell.

[0227] It should be noted that the above is only an exemplary listing of several types of cell information of the first cell and does not constitute a limitation on the cell information of the embodiment of the present application.

[0228] Exemplarily, the second device may uniquely identify a cell through MNC, MCC, Cell ID and frequency information, may uniquely identify a cell through MNC, MCC and LAC, or may uniquely identify a cell based on cell location information acquired through GPS.

[0229] refer to Figure 4 , Figure 4 A flowchart of another cell changing method is also provided, which is executed by a second device, and the method includes:

[0230] S401: Collect abnormal cell information sent by multiple terminal devices; wherein the abnormal cell information at least indicates an abnormal cell;

[0231] S402: When a condition for sending abnormal cell information is met, the collected abnormal cell information is sent to the first device, where the abnormal cell information is used by the first device to control the first device to change the cell when the first cell currently connected is determined to be recorded as an abnormal cell.

[0232] Exemplarily, the second device may be connected to multiple terminal devices, wherein the first device is any terminal device among the multiple terminal devices connected to the second device. When each terminal device connected to the second device determines that the cell it is currently connected to is an abnormal cell, it obtains the cell information of the cell and sends the obtained cell information to the second device.

[0233] Correspondingly, the second device receives the cell information sent by each terminal device, and stores the received cell information as abnormal cell information.

[0234] Exemplarily, since the second device stores cell information of multiple abnormal cells, when it is determined that the conditions for sending the abnormal cell information are met, the stored abnormal cell information can be sent to all terminal devices connected to the second device, so that the terminal device can determine whether the cell it is currently in is a recorded abnormal cell.

[0235] The abnormal cell information sent by the second device to each terminal device may further include the latest time when the abnormality occurs in each abnormal cell and the number of times the abnormality occurs in each cell.

[0236] In one embodiment, when the abnormal cell information sending condition is met, sending the collected abnormal cell information to the first device includes:

[0237] When a first preset time interval is reached, sending the collected abnormal cell information to the first device;

[0238] or,

[0239] When it is determined that the first device is in a preset state, the collected abnormal cell information is sent to the first device.

[0240] Exemplarily, the second device may send abnormal cell information to all terminal devices every time the first preset time interval is reached, so that each terminal device can determine whether the cell in which it is currently located has been recorded as an abnormal cell.

[0241] Considering that abnormal cells usually account for a small proportion of a large number of cells, and the number of terminal devices in each cell is also large, sending abnormal cell information to all terminal devices at every first preset time interval will occupy a large amount of network resources. Therefore, when receiving the first message sent by the first device, the currently stored abnormal cell information can also be sent to the first device.

[0242] In one embodiment, the method further comprises:

[0243] A first preset value and / or a second preset value is sent to the first device, wherein the first preset value and / or the second preset value is used by the first device to determine whether the first cell is in a preset state.

[0244] Exemplarily, after sending abnormal cell information to the first device, the second device can configure the corresponding first preset value and / or second preset value for the first device according to the device type of the first device or the user profile of the user to which the first device belongs, and send the first preset value and the second preset value configured for the first device to the first device.

[0245] Exemplarily, the second device may also send the first preset value and / or the second preset value to all terminal devices connected to the second device at every third preset time interval, so that all terminal devices may update the locally stored first preset value and / or second preset value according to the currently received first preset value and / or second preset value.

[0246] In one embodiment, the collecting abnormal cell information sent by multiple terminal devices includes:

[0247] receiving cell information of a first cell sent by the first device, wherein the first device is any terminal device among the multiple terminal devices;

[0248] The cell information is stored as abnormal cell information.

[0249] Exemplarily, when the first device determines that the first cell is an abnormal cell, the cell information of the first cell can be sent to the second device. Accordingly, after receiving the cell information of the first cell sent by the first device, the second device can check whether the cell information of the first cell exists in the stored abnormal cell information. When the cell information of the first cell is included in the stored abnormal cell information, it means that the first cell has been recorded as an abnormal cell. At this time, the stored occurrence time and number of occurrences of the abnormality of the first cell signal can be updated according to the reception time of the cell information of the first cell sent by the first device.

[0250] When the first cell has not been recorded as an abnormal cell before, the cell information of the first cell may be stored as abnormal cell information.

[0251] The cell information of the first cell recorded by the second device at least includes:

[0252] The mobile network code of the first cell;

[0253] The mobile country code of the first cell;

[0254] a cell identifier of the first cell;

[0255] The frequency information of the first cell.

[0256] refer to Figure 5 The embodiment of the present application also provides a cell replacement method, including:

[0257] The cell information of the abnormal cell is obtained, wherein the abnormal cell is a cell with normal RSRP and RSRQ but poor SINR, for example, RSRP is about -90dbm, but SINR is less than 0.

[0258] When the first device determines that the first cell currently located is an abnormal cell, the cell information of the first cell is sent to the cloud, and the cloud records the cell information of the first cell as abnormal cell information, wherein the abnormal cell information stored in the cloud includes: MCC, MNC, TAC, Cell_ID, earfcn (frequency band information), PCI, band (frequency band information) and location information.

[0259] The cloud can also regularly send the stored abnormal cell information to each terminal device. If the terminal device determines that the current cell is an abnormal cell based on the abnormal cell information sent by the cloud, it will receive sinr_th (first preset value), timer_th (second preset value) and / or sinr_hys sent by the cloud.

[0260] Specifically, the overall process of the scheme is as follows, where S302 to S305 are the cloud-based acquisition of abnormal cell information, and S306 to S318 are specific schemes for improving the abnormal network paging rate based on the abnormal cell information. The value range of sinr_th is (-84, -24)qdb, and the default is -40qdb, i.e. -10db (1db = 4qdb). The value range of timer_th (second preset value) is (20, 170) seconds, and the default is 60 seconds. The value range of sinr_hys is (4, 16)qdb, and the default is 8ddb, i.e. 2db.

[0261] The specific plan is as follows:

[0262] S501: Start;

[0263] S502: Determine whether the first cell where the first device is located is a cell with normal RSRP and RSRQ but poor SINR. If yes, execute S503; if not, execute S504;

[0269] S508: The cloud sends sinr_th, timer_th and / or sinr_hys to the first device;

[0270] S509: Continue monitoring and execute S507;

[0271] S510: Determine whether the SINR of the first cell is less than sinr_th, if yes, execute S511, if no, execute S512;

[0272] S511: Start timing time and execute S513;

[0273] S512: Continue monitoring and judging, and execute S510;

[0274] S513: Determine whether time is greater than or equal to timer_th, if yes, execute S514, if no, execute S515;

[0275] S514: Triggering the OOS to escape from the first cell, and executing S516;

[0276] S515: Continue monitoring and judging, and execute S513;

[0277] S516: Determine whether the SINR of the second cell is greater than or equal to sinr_th+sinr_hys (third preset value). If yes, execute S517; if no, execute S518.
