In the related art, a terminal device stores and maintains a list of historically camped cells, which includes information such as frequency bands, center frequencies, and cell identifiers of cells where the terminal device has camped in the past period of time. And, the cells included in the list are sorted according to the priority order and signal strength of their frequency bands. In this way, when the terminal device is powered on or searches the network, it will first select a cell according to the signal strength of the cell in the historical cell list. cell until a cell that satisfies the conditions is searched, and then camps on the cell.

In the related art, the terminal equipment selects and camps on the basis of the signal strength of the cell and does not consider the data quality of the cell. With the development of communication technology, users have higher and higher requirements on the data transmission quality of the network. How to implement camping on a cell with better network transmission quality is an urgent problem to be solved at present.

In this way, the terminal device can select a cell with better transmission quality to camp on, thereby improving the quality of data transmission in the cell after camping.

Hereinafter, the cell camping method provided by the embodiments of the present application will be described in detail with reference to the accompanying drawings.

An embodiment of the present application provides a cell camping method. FIG. 2 is a schematic flowchart of the implementation of the cell camping method according to an embodiment of the present application. As shown in FIG. 2 , the method may include the following steps 210 to 230 .

Step 210: The terminal device selects a cell that satisfies the camping condition from a plurality of historical camping cells to obtain at least one candidate camping cell.

It should be understood that when the terminal device is powered on, or re-searches the network after being disconnected from the network, the terminal device can preferentially search for the historically camped cells to determine whether the historically camped cells meet the camping conditions, so as to select from the historically camped cells. A cell is camped on.

In some embodiments, the terminal device may store relevant information of multiple historically camped cells in the past period of time, or relevant information of a certain number of historically camped cells. Exemplarily, the terminal device may store the relevant information of the historically camped cells within 24 hours of the terminal device, or the terminal device may store the relevant information of the historically camped cells at most 30. This embodiment of the present application does not limit this.

In some embodiments, the related information of the historically residing cell includes, but is not limited to, cell identification information, frequency band information, center frequency point information, and the like of the historically residing cell.

Further, the terminal device may search the stored multiple historically-resident cells based on the related information of the stored multiple historically-resident cells, and judge whether the stored multiple historically-resident cells meet the camping conditions.

In some embodiments, the residency condition may be an S criterion. That is, the received power of the cell is>0, and the received quality of the cell is>0.

It can be understood that, after searching for a historically camped cell, the terminal device can measure whether the signal quality of the historically camped cell satisfies the S criterion. The historical camping cell is determined as a candidate camping cell.

It should be noted that the terminal device may search and judge multiple historical camping cells one by one, and obtain one or more candidate camping cells that satisfy the camping conditions. If none of the multiple historical camping cells meet the camping conditions, the terminal device performs a full frequency band search on the current network in order to obtain a target cell that can camp on.

Step 220: The terminal device determines a target cell from the at least one candidate camping cell based on the transmission rate information corresponding to the at least one candidate camping cell.

In this embodiment of the present application, the terminal device may also store the transmission rate information of each historically residing cell. The transmission rate information refers to the uplink data transmission rate and/or the downlink data transmission rate of a historically camped cell when the terminal device resides in a historically camped cell.

In some embodiments, the transmission rate information includes, but is not limited to, an average rate of data transmission, a maximum rate of data transmission, an equalized rate of data, and the like.

In a possible implementation manner, when a terminal device resides in a historically camped cell, the terminal device may, in the process of transmitting service data, determine the transmission rate information of the historically camped cell according to the transmission situation of the service data , and store the transfer rate information. That is, the terminal device can passively acquire the transmission rate information of the historically camped cell.

In another possible implementation manner, when a terminal device resides in a historically camped cell, the terminal device may actively initiate measurement of the transmission rate of the historically camped cell, and obtain the historically camped cell according to the measurement result of the transmission rate. Save the transmission rate information of the cell, and store the transmission rate information. That is, the terminal device can actively measure the transmission rate information of the historically camped cell. This embodiment of the present application does not limit the acquisition process of the transmission rate information.

In the embodiment of the present application, after determining the candidate camping cells, the terminal device may determine the target cell to camp on from at least one candidate camping cell according to the transmission rate information of the candidate cells.

Exemplarily, the terminal device may determine a candidate camping cell with the highest transmission rate from at least one candidate camping cell as the target cell, and the terminal device may also determine a candidate camping cell with a transmission rate greater than a preset threshold from the at least one candidate camping cell. The remaining cell is used as the target cell. This embodiment of the present application does not limit this.

Step 230: The terminal device performs a cell camping operation on the target cell.

It should be understood that after the terminal device determines the target cell, the terminal device may perform a cell camping operation to camp on the target cell. After the terminal device resides in the target cell, it can perform procedures such as network registration and random access to realize uplink data synchronization.

It can be seen that, in the cell camping method provided by the embodiment of the present application, the terminal device can select a cell that satisfies the camping conditions from a plurality of historical camping cells to obtain at least one candidate historical camping cell; The transmission rate information corresponding to the at least one candidate historical camping cell determines the target cell from the at least one candidate historical camping cell; finally, the terminal device may perform a cell camping operation for the target cell. That is to say, in the cell camping method provided by the embodiment of the present application, the terminal device can select a target cell for camping on the candidate historical camping cells that can be camped on according to the transmission rate information of the historical camping cell. In this way, the terminal device can select a cell with better transmission quality for camping, thereby improving the quality of data transmission in the cell after camping, and optimizing the user's data surfing experience.

In some embodiments, the terminal device may store and maintain a list of historical camping cells, and store the relevant information of the above-mentioned multiple historical camping cells through the historical camping cell list. That is to say, the terminal device records cell identification information, frequency band information, and center frequency point information of a plurality of historically camped cells through the list of historically camped cells.

In this way, when the terminal device is powered on or searches the network again after being disconnected from the network, it can read the list of historically resident cells. Then, searching for the historically resident cells is performed by using the cell identification information, frequency band information, and center frequency point information of the plurality of historically resident cells stored in the list of historically resident cells to obtain a search result. Next, the terminal device judges whether the historical camping cell satisfies the camping condition according to the search result of each historical camping cell, and then selects a cell for camping on the historical camping cell that satisfies the camping condition.

In some embodiments, the above-mentioned historical camping cell list may further store transmission rate information of each historical camping cell.

Based on this, in step 220, the terminal device determines the target cell from the at least one candidate camping cell based on the transmission rate information corresponding to the at least one candidate camping cell, including:

The terminal device obtains the transmission rate information corresponding to at least one candidate camping cell from the list of historical camping cells;

The terminal device determines the target cell from the at least one candidate camping cell based on the transmission rate information corresponding to the at least one candidate camping cell.

It can be understood that, after determining at least one candidate camping cell, the terminal device can read the transmission rate information corresponding to each candidate camping cell from the historical camping cell list. And based on the transmission rate information of each candidate camping cell, a target cell to camp on is determined from at least one candidate camping cell.

In some embodiments, the plurality of historical camping cells in the historical camping cell list are sorted according to the size of the transmission rate of the historical camping cells.

Wherein, the plurality of historically resident cells in the list of historically resident cells may be arranged in ascending order according to the transmission rate, or may be arranged in descending order according to the transmission rate. This embodiment of the present application does not limit this.

In some embodiments, the terminal device records and maintains a list of related information of cells where the terminal device has camped through the historical cell maintenance module of the access layer protocol stack, and sorts the plurality of historically camped cells according to the transmission rate.

In some embodiments, in step 220, the terminal device determines the target cell from the at least one candidate camping cell based on the transmission rate information corresponding to the at least one candidate camping cell, which may be implemented in the following manner:

The terminal device determines, based on the transmission rate information corresponding to the at least one candidate camping cell, a cell whose transmission rate satisfies the selection condition from the at least one candidate camping cell, and obtains the target cell.

Wherein, the selection condition includes at least one of the following:

The transmission rate is the cell with the largest transmission rate in at least one candidate historically resident cell;

The transfer rate is greater than the rate threshold.

In some embodiments, when the number of candidate camping cells is only one, the terminal device may directly determine the candidate camping cell as the target cell. Alternatively, the terminal device may determine whether the transmission rate of the candidate camping cell is greater than the rate threshold, and if it is greater than the rate threshold, the terminal device determines the candidate camping cell as the target cell.

In some embodiments, when the number of candidate camping cells includes multiple ones, the terminal device may select the cell with the highest transmission rate from the multiple candidate camping cells according to the transmission rate information of each candidate camping cell as the The target cell to camp on.

In other embodiments, when the number of candidate camping cells includes multiple ones, the terminal device may select a transmission rate greater than a rate threshold from the multiple candidate camping cells according to the transmission rate information of each candidate camping cell as the target cell to camp on.

Here, if the number of candidate camping cells with the transmission rate greater than the rate threshold is multiple, the terminal device determines the cell with the highest transmission rate as the target cell to camp on.

In some embodiments, when the number of candidate camping cells includes multiple ones, the terminal device may sort the plurality of candidate camping cells according to the data transmission rate of each candidate camping cell, according to the highest transmission rate. Camping is attempted on multiple candidate camping cells in order of low order.

In some embodiments, the plurality of historical camping cells in the historical cell list maintained by the terminal device may be sorted according to the size of the transmission rate. In this way, the terminal device can directly select the cell with the smallest index number from the candidate camping cells according to the sequence of the index numbers of the candidate camping cells, as the target cell to be camped on. In this way, the computing resources of the electronic device can be saved, and the camping efficiency of the cell can be improved.

In practical applications, the priority order of camping on the candidate camping cell can also be configured. The priority order of the candidate camping cells may be related to the radio access standard of the network. For example, the terminal device can preferentially access the candidate camping cells using the 5G network, and when there is no cell using the 5G standard in the candidate camping cells, the terminal device can select the candidate camping cells using the LTE network.

In some embodiments, the terminal device may determine the target cell by combining the transmission rate of the candidate camping cells and the priority order of the candidate camping cells.

Exemplarily, the terminal device may preferentially select a candidate camping cell with a high priority, and if the number of candidate camping cells with a high priority is multiple, the terminal device may select from multiple high-priority candidate camping cells. The candidate camping cell with the highest transmission rate is used as the target cell.

In an embodiment of the present application, referring to the schematic flowchart shown in FIG. 3 , in step 210, the terminal device selects a cell that satisfies the camping conditions from a plurality of historical camping cells, and obtains at least one candidate historical camping cell before obtaining at least one candidate historical camping cell. Perform the following steps:

Step 202, in the case of accessing the first cell, the terminal device acquires the transmission rate information of the first cell;

Step 204: The terminal device constructs a list of historically camped cells based on the transmission rate information of the first cell.

Wherein, the first cell is any one of multiple historical camping cells.

That is, when a terminal device camps on and accesses any cell, the terminal device can obtain the transmission rate information of the cell and other related information of the cell, such as cell identification information, frequency band information, center frequency point information, etc.

In this way, after the terminal device obtains the transmission rate information of the cell and other related information, it can construct a list of historically camped cells according to the transmission rate information and other related information of the cell, so that the terminal device can search the network next time or turn it on. Cell camping is performed using the historical camping cell list.

In some embodiments, if the terminal device has stored a list of historically camped cells, the terminal device may update the above-mentioned transmission rate information of the first cell and other related information to the list of historically camped cells.

In some embodiments, when the terminal device updates the list of historical camping cells, it may determine the arrangement position of the first cell in the historical camping cell list based on the transmission rate information of the first cell, so that the historical camping cell located before the first cell The rate information of the cell is smaller than the transmission rate of the first cell, and the rate information of the historically residing cell located after the first cell is greater than the transmission rate of the first cell.

In some embodiments, when the terminal device accesses the first cell in step 202, acquiring the transmission rate information of the first cell may be implemented by the following steps:

Step 2021, when the terminal device accesses the first cell, sends a measurement signal to the network device;

Step 2022: Receive a feedback signal from the network device, and determine the transmission rate information of the first cell based on the feedback signal.

In this embodiment of the present application, when a terminal device resides in any cell, it can actively initiate measurement of the transmission rate of the residing cell, and count at least one of the average rate, the highest rate, or the balanced rate over a period of time.

Specifically, the terminal device may send a measurement signal to the network device corresponding to the currently camped first cell, and receive a feedback signal returned by the network device based on the measurement signal. In this way, the terminal device can determine the transmission rate information of the first cell based on the measurement signal and the feedback signal.

In some embodiments, the measurement signal may be service data sent by the terminal device to the network device, or may be a signal dedicated to transmission rate measurement. This embodiment of the present application does not limit this.

In this way, when the terminal device is powered on or searches the network next time, the terminal device can select a target cell to camp on from the candidate historical camping cells that can camp on according to the transmission rate information of the historical camping cells. In this way, the terminal device can select a cell with a higher transmission rate to camp on based on the transmission rate rate, thereby improving the transmission quality of the cell after camping.

In an embodiment of the present application, the embodiment of the present application further provides a method for generating a list of historically camped cells. Referring to the schematic flowchart shown in FIG. 4 , the method for generating a list of historically camped cells may include steps 410 and 420 .

Step 410: In the case of accessing the first cell, the terminal device obtains the transmission rate information corresponding to the first cell; the first cell is any one of the multiple historically camped cells of the terminal device; the transmission rate information is used to enable the The terminal device determines a target cell for performing the cell camping operation from a plurality of historical camping cells;

Step 420: The terminal device constructs a list of historically camped cells based on the transmission rate information corresponding to the first cell.

It can be understood that when a terminal device camps on and accesses any cell, the terminal device can obtain the transmission rate information of the cell and other related information of the cell, such as cell identification information, frequency band information, center frequency point information, etc. .

In this way, after the terminal device obtains the transmission rate information of the cell and other related information, it can construct a list of historically camped cells according to the transmission rate information and other related information of the cell, so that the terminal device can search the network next time or turn it on. Cell camping is performed using the historical camping cell list.

In some embodiments, if the terminal device has stored a list of historically camped cells, the terminal device may update the above-mentioned transmission rate information of the first cell and other related information to the list of historically camped cells.

In some embodiments, when the terminal device updates the list of historical camping cells, it may determine the arrangement position of the first cell in the historical camping cell list based on the transmission rate information of the first cell, so that the historical camping cell located before the first cell The rate information of the cell is smaller than the transmission rate of the first cell, and the rate information of the historically residing cell located after the first cell is greater than the transmission rate of the first cell.

In some embodiments, when a terminal device camps on any cell, it can actively initiate measurement of the transmission rate of the camped cell, and count at least one of the average rate, the highest rate, or the balanced rate within a period of time.

Specifically, when accessing the first cell, the terminal device sends a measurement signal to the network device corresponding to the first cell; and the terminal device receives the feedback signal from the network device, and determines the transmission rate information of the first cell based on the feedback signal.

Specifically, in the embodiment of the present application, the terminal device may send a measurement signal to the network device, and receive a feedback signal returned by the network device based on the measurement signal. In this way, the terminal device can determine the transmission rate information of the first cell based on the measurement signal and the feedback signal.

In some embodiments, the measurement signal may be service data sent by the terminal device to the network device, or may be a signal dedicated to transmission rate measurement. This embodiment of the present application does not limit this.

It can be seen from this that, in the method for generating the list of historically camped cells provided by the embodiments of the present application, the terminal device can store the transmission rate information of the cells where the terminal device has been camped in the list of historically camped cells, so that the terminal device can be switched on the next time or When searching the network, the terminal device can select a target cell to camp on from the candidate historical camping cells that can be camped on according to the transmission rate information of the historical camping cells. In this way, the terminal device can select a cell with better transmission quality to camp on based on the transmission rate, thereby improving the transmission quality of the cell after camping.

The relevant information of the current cell includes, but is not limited to, cell identification information, frequency band information, center frequency point information, and the like of the current cell.

In addition, the transmission rate information of the cell includes, but is not limited to, the average rate, the highest rate, and the balanced rate within a period of time.

Further, as shown in FIG. 5 , the terminal device may store the relevant information of the current cell in the list of historically camped cells according to the transmission rate information of the current cell.

Specifically, the terminal device can sort the current cell and all historically resident cells according to the transmission rate information, determine the position of the current cell in the list of historically resident cells, and store the relevant information of the current cell according to the determined position to obtain List of historical camped cells.

In some embodiments, the historical cell maintenance module of the access layer protocol stack of the terminal device records and maintains a list of historical information of the cells where it resides, and sorts it according to the algorithm of the data traffic rate.
