[0028] The embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present disclosure can be combined with each other without conflict.

[0029] In the related art, in the process of acquiring the system information of a cell, it is necessary to sort the reference signal receiving power (RSRP) measurement value of each cell from large to small, and try to read the system information of the cell broadcasted by the base station in sequence.

[0030] However, there may be a situation where a cell with a larger RSRP measurement value is not actually the most suitable cell to stay in, or even a cell that cannot be stayed in. If this sorting method is still used to read system messages, the terminal device will continue to try to read system messages and fail until the reading time threshold is exceeded before the system message of the next cell can be read, which will increase the power consumption of the terminal device, increase the time to access the cell, and reduce the working efficiency of the terminal device.

[0031] In order to improve the technical problem that in the current related technology, the terminal device continuously attempts to read the system message but fails until the reading time threshold is exceeded before the system message of the next cell can be read, thereby increasing the power consumption of the terminal device, prolonging the time to access the cell, and reducing the working efficiency of the terminal device. This embodiment provides a communication method, such as Figure 1 As shown, the method includes:

[0032] Step 101: Obtain first RSRP measurement values ​​of multiple cells.

[0033] In some examples, the method shown in the present disclosure can be executed by a terminal device, which can be called a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device can also be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, and a chip or chip system, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal device.

[0034] In one embodiment, obtaining first RSRP measurement values ​​of multiple cells includes receiving first RSRP measurement values ​​of multiple cells reported by a physical layer.

[0035] For this embodiment, the physical layer is the first layer of the Open System Interconnection Reference Model (OSI). Although it is at the bottom layer, it is the foundation of the entire open system. The physical layer provides transmission media and interconnection equipment for data communication between devices, and provides a reliable environment for data transmission. The physical layer can provide a data terminal device with a path for transmitting data and can also provide data transmission services, for example, ensuring that data can pass through it correctly and providing sufficient bandwidth.

[0036] In an embodiment of the present application, multiple cells are terminal devices that measure the frequencies sent by the network device in sequence according to the frequency priorities, and multiple cells may exist on each frequency.

[0037] It should be noted that the network equipment may be a base station, which is the abbreviation of base station subsystem (BSS). Taking the GSM network as an example, it includes a base transceiver station (BTS) and a base station controller (BSC). A base station controller can control dozens or even dozens of base transceivers.

[0038] In some examples, the first RSRP measurement value is an RSRP measurement value corresponding to the cell obtained when the terminal device measures the frequency point.

[0039] Step 102: Based on the historical system message reading results of multiple cells, adjust the first RSRP measurement value to obtain a second RSRP measurement value.

[0040] In an embodiment of the present application, the historical message reading results may include the reading results of the terminal device's last reading of system messages for multiple cells. For example, for cell a, cell b, cell c, and cell d, the last reading result for cell a may be a reading failure, the last reading result for cell b may be a reading failure, and the last reading result for cell c may be a reading success.

[0041] It should be noted that the second RSRP measurement value is obtained by adjusting the first RSRP measurement value based on the historical message reading result.

[0042] Step 103: Determine the current system message reading order of the multiple cells according to the second RSRP measurement value.

[0043] In some examples, the current system message reading order of the multiple cells is obtained according to the second RSRP measurement values ​​from large to small.

[0044] Compared with the related art, this embodiment obtains and saves the results of system message reading, adjusts the RSRP measurement values ​​of multiple cells, and obtains the adjusted order of reading system messages for multiple cells, thereby avoiding the situation where the terminal device repeatedly attempts to read the system message, reducing the power consumption of the terminal device, reducing the time for the terminal device to access the cell, and improving the working efficiency of the terminal device. Based on the adjusted system message reading order, the terminal device can reside in a better cell, so that the terminal device can have lower transmission power and retransmission times, further reducing power consumption.

[0045] Further, in order to illustrate the specific implementation process of the method of this embodiment, this embodiment provides the following Figure 2 The specific method shown, wherein the method includes:

[0046] Step 201: Obtain first RSRP measurement values ​​of multiple cells.

[0047] Exemplarily, the network device sends three frequencies A, B, and C to the terminal device. The terminal device measures frequencies A, C, and B one by one in the order of their priority, and can obtain cells a and b included in frequency A, cells c and d included in frequency C, and cells e and f included in frequency B. For frequencies A, C, and B, the multiple cells are cells a, b, c, d, e, and f.

[0048] Furthermore, for frequency A, frequency C, and frequency B, we can obtain cell a and cell b included in frequency A, cell a corresponds to RSRP measurement value a, cell b corresponds to RSRP measurement value b, cell e and cell f included in frequency B, cell e corresponds to RSRP measurement value e, cell f corresponds to RSRP measurement value f, and so on, and examples are not given one by one here.

[0049] Step 202: Based on the historical system message reading result, determine the current RSRP adjustment values ​​of multiple cells.

[0050] Optionally, step 202 may specifically include: analyzing the reading results of the last system message reading for multiple cells in the historical system message; based on the reading results, adjusting the RSRP adjustment value used by each of the multiple cells when the system message was last read, to obtain the current RSRP adjustment values ​​of the multiple cells.

[0051] In the embodiment of the present application, the RSRP adjustment value is obtained based on historical system messages.

[0052] For example, for cells a, cell b, cell c, cell d, cell e and cell f, in the historical system message reading results, the last reading result for cell a may be a reading failure, the last reading result for cell b may be a reading failure, and the last reading result for cell c may be a reading success.

[0053] Accordingly, the RSRP adjustment values ​​used when the system message of the cells a, b and c was read last time can be adjusted, and the RSRP adjustment values ​​of the current cells a, b and c can be obtained.

[0054] In some examples, step 202 specifically further includes: if the target cell among the multiple cells is read successfully, the RSRP adjustment value used when the system message of the target cell was read last time is reduced by one unit value to obtain the current RSRP adjustment value of the target cell.

[0055] Optionally, the target cell may be any one of the multiple cells. For example, the multiple cells are cell a, cell b and cell c, and the target cell may be any one of cell a, cell b and cell c.

[0056] For example, if the last reading result of cell c is successful, and the RSRP adjustment value used when reading the system message of cell c last time is 1, 1 can be reduced by one unit value, that is, 1 is adjusted to 0 as the current RSRP adjustment value of cell c.

[0057] For this embodiment, step 202 specifically further includes: if the target cell reading fails in the reading result, analyzing the reason for the failure to read the system message of the target cell; and determining the current RSRP adjustment value of the target cell based on the analysis result.

[0058] For example, if the last reading result of cell a was a reading failure and the last reading result of cell b was a reading failure, it is necessary to determine the reasons for the reading failure of cells a and cell b. Based on the different reasons, the RSRP adjustment values ​​used when the system message was last read for cells a and cell b are adjusted respectively, and then the current RSRP adjustment values ​​of cells a and cell b are determined.

[0059] In an embodiment of the present application, step 202 specifically also includes: if it is determined based on the analysis result that the reason for the failure to read the system message of the target cell is a preset failure reason, the RSRP adjustment value used for the last system message reading of the target cell is increased by one unit value to obtain the current RSRP adjustment value of the target cell.

[0060] It should be noted that the preset failure reasons include large cell interference, low signal-to-noise ratio, etc. The preset failure reasons can be set as needed. The specific types of the preset failure reasons are not specifically limited in the embodiments of the present application.

[0061] For example, if the reason for the reading failure of cell a is analyzed to be the preset failure reason, the RSRP adjustment value used when the system message of cell a was read last time was 1, and 1 can be increased by one unit value, that is, 1 is adjusted to 2, as the current RSRP adjustment value of cell a.

[0062] As an optional manner, step 202 specifically further includes: in response to the RSRP adjustment value used in the last system message reading of the target cell being a preset initialization value, determining the preset initialization value as the current RSRP adjustment value of the target cell.

[0063] Exemplarily, if the last reading result of cell c is successful, the preset initialization value is 0, and the RSRP adjustment value used when the system message of cell c was read last time is 0, the preset initialization value 0 is used as the current RSRP adjustment value of cell c.

[0064] Furthermore, step 202 specifically includes: if all the multiple cells in the reading result fail to be read based on a preset failure reason, determining the preset initialization value as the current RSRP adjustment value of the multiple cells.

[0065] In some examples, if the multiple cells are cell a, cell b and cell c, the last reading result of cell a was a reading failure based on a preset reason, the last reading result of cell b was a reading failure based on a preset reason, and the last reading result of cell c was a reading failure based on a preset reason, that is, all the multiple cells failed to read based on the preset failure reason, and the current adjustment values ​​of cells a, cell b and cell c are all set to the preset initialization values.

[0066] Further optionally, step 202 specifically includes: if it is determined based on the analysis result that the cause of the failure to read the system message of the target cell is other than the preset failure cause, the RSRP adjustment value used for the last system message reading of the target cell is determined as the current RSRP adjustment value of the target cell.

[0067] In the embodiment of the present application, if the reason for the reading failure of cell b is analyzed to be other than the preset failure reason, and the RSRP adjustment value used when the system message of cell b was read last time is 1, then 1 is used as the current RSRP adjustment value of cell a.

[0068] It should be noted that other reasons other than the preset failure reasons may be dual-card punching, single antenna reception performance loss, and inconsistent intra-window and inter-window merging strategies, etc. Other reasons other than the preset failure reasons can be set as needed. The specific types of other reasons other than the preset failure reasons are not specifically limited in the embodiments of the present application.

[0069] Step 203: Based on the current RSRP adjustment values ​​of the multiple cells, the first RSRP measurement value is adjusted to obtain a second RSRP measurement value.

[0070] Optionally, before step 203, the method of this embodiment may include: saving the current RSRP adjustment values ​​of the multiple cells in a preset storage location of the terminal device.

[0071] For example, if the current RSRP adjustment value of cell a is 1, the current RSRP adjustment value of cell b is 2, and the current RSRP adjustment value of cell c is 0, the current adjustment values ​​of cells a, b, and c are all saved in the terminal device.

[0072] Step 204: Determine the current system message reading order of the multiple cells according to the second RSRP measurement value.

[0073] For this embodiment, before step 204, the method of this embodiment further includes: reading system messages from multiple cells in a system message reading order.

[0074] In some examples, before step 204, the method of this embodiment further includes: updating a first decision condition for residing in multiple cells based on current RSRP adjustment values ​​of the multiple cells to obtain a second decision condition; and determining a second cell in the multiple cells that does not meet the second decision condition based on the second decision condition.

[0075] Among them, the terminal device no longer obtains the first RSRP measurement value of the second cell reported by the physical layer.

[0076] Optionally, the 3rd Generation Partnership Project (3GPP) standard describes the criteria for camping on a cell, and the first decision condition needs to satisfy Formula 1 and Formula 2 as shown below:

[0077] Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)–Pcompensation

[0078] -Qoffsettemp(Formula 1)

[0079] Squal=Qqualmeas–(Qqualmin+Qqualminoffset)-Qoffsettemp

[0080] (Formula 2)

[0081] In Formula 1 and Formula 2, Srxlev>0 and Squal>0, Srxlev represents the strength of the received signal power of the currently connected base station monitored by the terminal device (Serving cell received signal strength measurement, Srxlev), Qrxlevmeas represents the measured value of the received signal quality, Qrxlevmin represents the minimum channel requirement for cell reselection, and offset represents a function.

[0082] The RSRP adjustment value can adjust the measurement values ​​Qrxlevmeas and Qqualmeas reported by the physical layer. That is, the second decision condition must satisfy the following formulas 3 and 4:

[0083] Srxlev=Qrxlevmeas-Temp RSRP –(Qrxlevmin+Qrxlevminoffset)–

[0084] Pcompensation-Qoffsettemp (Formula 3)

[0085] Squal=Qqualmeas-Temp RsRP –(Qqualmin+Qqualminoffset)-

[0086] Qoffsettemp(Formula 4)

[0087] In Formula 3 and Formula 4, Temp RSRP Indicates the RSRP adjustment value.

[0088] It should be noted that after the criteria for staying in a cell are optimized, a cell that fails to obtain system messages too many times will not meet the stay conditions, so that the terminal device can directly skip such cells during the cell search process and give priority to or reselect other better cells, thereby achieving the effect of shortening latency and reducing power consumption.

[0089] In a cellular mobile communication network, taking the terminal device as UE as an example, the cell base station will broadcast system messages, including MIB, including network attached storage (NAS) information and timers and counters (SIB1) in idle mode and connected mode of UE, system message 2 (SIB2), including cell selection and reselection parameters (SIB3) in idle mode of UE and other system messages. Among them, the management information base (MIB), SIB1, SIB2 are necessary system messages for UE to stay in the cell. If the necessary system messages fail to be obtained, the UE considers that the cell cannot be stayed. When the UE is turned on for cell selection, or when reselecting a cell in idle mode, or when it loses coverage, or when reselecting from other radio access technology (Radio Access Technolog, RAT) cells, it is necessary to first measure according to the frequency priority to obtain that there may be multiple cells on the frequency point, and try to read the system message of the cell broadcast by the base station according to the RSRP of the cell from large to small, until a suitable cell for staying is found or a better cell is reselected.

[0090] In the related technical solutions, there may be a scenario where the UE fails to obtain system messages. If the system message fails to be obtained within a certain system message period, the UE will generally try more system message periods to obtain the system message broadcast by the cell. When the UE fails to obtain the necessary system message for residence at a specific time, the UE may think that the cell cannot be resided. In some special scenarios of the related technical solutions, such as cells with a large RSRP, abnormalities or other interferences may occur, resulting in a lower signal-to-noise ratio. In fact, it is not the most suitable cell to reside in or the cell cannot be resided in. If the UE keeps trying to reside in the cell to read the system message, it will cause increased latency and power consumption.

[0091] like Figure 3 As shown, taking the terminal device as UE as an example, there are two frequency points and each frequency point has two cells. During the cell search process, the UE Figure 4As shown, frequency 1 is measured first according to the frequency priority, and it is found that there are two cells: cell 1 and cell 2. The RSRP1 of cell 1 is greater than the RSRP2 of cell 2. The UE attempts to read the system message of cell 1. If cell 1 encounters the special scenarios mentioned in Section 1.2 above, such as cell abnormality or interference, there will be two results. Result 1: the UE attempts to read the system message of cell 1 for a long time, and finally succeeds after multiple failures; Result 2: the UE attempts to read the system message of cell 1 for a long time and finally fails. The UE attempts to obtain the system message of cell 2. If it fails, it continues to try the cell of frequency 2. The UE may trigger the cell selection or cell reselection process multiple times. If it follows the above steps each time and tries to read the system message of cell 1 in the order of RSRP size, it will cause large delays and power consumption. Even if cell 1 meets the conditions for staying, the UE does not try other cells that may have a higher signal-to-noise ratio and smaller delay. If the UE performs data or telephone services on cells with lower signal-to-noise ratios for a long time, it will also cause higher delays, lower data service rates, and more retransmissions leading to higher power consumption.

[0092] Compared with the related art, this embodiment obtains and saves the results of system message reading, adjusts the RSRP measurement values ​​of multiple cells, thereby optimizing the order of cell search, avoiding the situation where the terminal device repeatedly attempts to read the system message, reducing the power consumption of the terminal device, reducing the time for the terminal device to access the cell, and improving the working efficiency of the terminal device. Based on the optimized system message reading order, the terminal device can reside in a better cell, so that the terminal device can have lower transmission power and retransmission times, further reducing power consumption.

[0093] In order to illustrate the specific implementation process of this embodiment, the following specific application examples are given, but are not limited thereto:

[0094] like Figure 5 As shown, taking the terminal device as UE as an example, the UE saves an RSRP adjustment value Temp for each detected cell. RSRP , the value is initially 0. If the acquisition of system information in the cell fails once, the Step value is incremented. If the cell acquires system information successfully and Temp RSRP >0, decrement Step until it reaches 0. If all cells cannot be camped or the UE enters the coverage loss state, the Temp of all cells RSRP Set to 0.

[0095] like Figure 6 As shown in the figure, each time the UE selects or reselects a cell, it first adjusts the RSRP value of the cell reported by the physical layer measurement, and then sorts the cells according to the RSRP size, and reads the system message and subsequent cell residence process according to the adjusted cell order. RSRP adjustment is to convert RSRP measurement value - adjustment value Temp RSRPThe result of the adjustment may be to optimize the position of the cells that have too many failed system cell reads in the next RSRP sorting process.

[0096] Compared with the related art, this embodiment obtains and saves the results of system message reading, adjusts the RSRP measurement values ​​of multiple cells, thereby optimizing the order of cell search, avoiding the situation where the terminal device repeatedly attempts to read the system message, reducing the power consumption of the terminal device, reducing the time for the terminal device to access the cell, and improving the working efficiency of the terminal device. Based on the optimized system message reading order, the terminal device can reside in a better cell, so that the terminal device can have lower transmission power and retransmission times, further reducing power consumption.

[0097] Further, as Figure 1 and Figure 2 The specific implementation of the method shown in this embodiment provides a communication device, such as Figure 7 As shown, the device includes: an acquisition module 31, an adjustment module 32, and a determination module 33.

[0098] An acquisition module 31 is configured to acquire first RSRP measurement values ​​of multiple cells;

[0099] An adjustment module 32 is configured to adjust the first RSRP measurement value based on the historical system message reading results of the multiple cells to obtain a second RSRP measurement value;

[0100] The determination module 33 is configured to determine the current system message reading order of the multiple cells according to the second RSRP measurement value.

[0101] In some examples of this embodiment, the adjustment module 32 is specifically configured to determine the current RSRP adjustment values ​​of the multiple cells based on the historical system message reading results; based on the current RSRP adjustment values ​​of the multiple cells, adjust the first RSRP measurement value to obtain a second RSRP measurement value.

[0102] In some examples of this embodiment, the adjustment module 32 is further configured to analyze the reading result of the last system message reading for the multiple cells in the historical system message; based on the reading result, the RSRP adjustment value used by each of the multiple cells when the system message was last read is adjusted to obtain the current RSRP adjustment values ​​of the multiple cells.

[0103] In some examples of this embodiment, the adjustment module 32 is further configured to, if the target cell among the multiple cells is read successfully, reduce the RSRP adjustment value used when the system message of the target cell was last read by one unit value to obtain the current RSRP adjustment value of the target cell.

[0104] In some examples of this embodiment, the adjustment module 32 is further configured to analyze the reason for the failure to read the system message of the target cell if the reading of the target cell in the reading result fails; and determine the current RSRP adjustment value of the target cell based on the analysis result.

[0105] In some examples of this embodiment, the adjustment module 32 is further configured to increase the RSRP adjustment value used for the last system message reading of the target cell by one unit value if it is determined based on the analysis result that the cause of the failure to read the system message of the target cell is a preset failure cause, so as to obtain the current RSRP adjustment value of the target cell.

[0106] In some examples of this embodiment, the adjustment module 32 is further configured to, in response to the RSRP adjustment value used for the last system message reading of the target cell being a preset initialization value, determine the preset initialization value as the current RSRP adjustment value of the target cell.

[0107] In some examples of this embodiment, the adjustment module 32 is further configured to determine the preset initialization value as the current RSRP adjustment value of the multiple cells if all the multiple cells in the reading result fail to read based on the preset failure reason.

[0108] In some examples of this embodiment, the adjustment module 32 is further configured to determine the RSRP adjustment value used for the last system message reading of the target cell as the current RSRP adjustment value of the target cell if it is determined based on the analysis result that the cause of the failure to read the system message of the target cell is other than the preset failure cause.

[0109] In some examples of this embodiment, the adjustment module 32 is further configured to save the current RSRP adjustment values ​​of the multiple cells in a preset storage location of the terminal device.

[0110] In some examples of this embodiment, the determination module 33 is further configured to read the system messages of the multiple cells according to the system message reading order.

[0111] In some examples of this embodiment, the determination module 33 is also configured to update the first decision condition for residing in the multiple cells based on the current RSRP adjustment values ​​of the multiple cells to obtain a second decision condition; based on the second decision condition, determine a second cell among the multiple cells that does not meet the second decision condition, wherein the terminal device no longer obtains the first RSRP measurement value of the second cell reported by the physical layer.
