In addition, the communication system may further include a terminal device 12. Terminal Equipment 12 may also be referred to as User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a drone device, a terminal device in a 5G Network or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, and the like, which are not limited in this embodiment.

In the related art, a historical residential cell list is stored and maintained in the terminal device, and the list includes information such as frequency bands, center frequency points, cell identifiers and the like of cells where the terminal device has been residential in a past period of time. And the cells contained in the list are sorted according to the priority order and the signal strength of the frequency bands. In this way, when the terminal device is turned on or searches for a network, the terminal device first performs cell selection according to the signal strength of the cells in the history resident cell list, and if no resident cell exists, searches for a suitable cell in a full frequency band according to an initial cell selection mode until a cell meeting a condition is searched, and then resides in the cell.
In the related art, the terminal device performs selection and camping according to the signal strength of the history resident cell, and does not consider the data quality of the cell. With the development of communication technology, users put higher and higher demands on the data transmission quality of the network. How to implement residence in a cell with better network transmission quality is a problem to be solved urgently at present.

The terminal equipment can select a cell meeting the residence condition from a plurality of historical resident cells to obtain at least one candidate historical resident cell; then, the terminal equipment determines a target cell from at least one candidate historical resident cell based on the transmission rate information corresponding to the at least one candidate historical resident cell; finally, the terminal device may perform a cell camping operation for the target cell. That is to say, according to the cell camping method provided in the embodiment of the present application, the terminal device may select a target cell from candidate camped cells that can camp on, to camp on, according to the transmission rate information of the history camped cells. Therefore, the terminal equipment can select the cell with better transmission quality to camp, thereby improving the data transmission quality of the camped cell.
Hereinafter, a cell camping method provided in the embodiments of the present application is described in detail with reference to the accompanying drawings.
An embodiment of the present application provides a cell camping method, and fig. 2 is a schematic flow chart illustrating an implementation of the cell camping method according to the embodiment of the present application, and as shown in fig. 2, the method may include the following steps 210 to 230.
Step 210, the terminal device selects a cell satisfying the camping condition from the plurality of historical camping cells to obtain at least one candidate camping cell.
It should be understood that, when the terminal device is turned on or searches for a network again after a network drop, the terminal device may preferentially search for the historical residential cells, determine whether the historical residential cells meet the residential conditions, and select one cell from the historical residential cells to camp on.
In some embodiments, the terminal device may store information related to a number of historical camped cells, or information related to a number of historical camped cells, over a period of time in the past. For example, the terminal device may store the related information of the historical camping cells within 24 hours of the terminal device, or the terminal device may store the related information of up to 30 historical camping cells. The embodiment of the present application does not limit this.
In some embodiments, the information related to the historical camping cell includes, but is not limited to, cell identification information, frequency band information, center frequency point information, and the like of the historical camping cell.
Further, the terminal device may search the stored multiple history residential cells based on the stored related information of the multiple history residential cells, and determine whether the stored multiple history residential cells satisfy the residential condition.
In some embodiments, the residency condition may be an S-criterion. I.e. the received power of the cell >0 and the received quality of the cell > 0.
It can be understood that, after searching a certain history resident cell, the terminal device may measure whether the signal quality of the history resident cell meets the S criterion, and if the signal quality of the history resident cell meets the S criterion, determine that the history resident cell meets the resident condition, and determine the history resident cell as a candidate resident cell.
It should be noted that the terminal device may search and determine the multiple historical residential cells one by one to obtain one or more candidate residential cells that satisfy the residence condition. And if the plurality of historical resident cells do not meet the resident condition, the terminal equipment searches the current network in full frequency band so as to obtain the target cell which can be resident.
Step 220, the terminal device determines a target cell from the at least one candidate resident cell based on the transmission rate information corresponding to the at least one candidate resident cell.
In this embodiment, the terminal device may further store transmission rate information of each historical camping cell. The transmission rate information refers to an uplink data transmission rate and/or a downlink data transmission rate of a history resident cell when the terminal device resides in the history resident cell.
In some embodiments, the transmission rate information includes, but is not limited to, an average rate of data transmission, a highest rate of data transmission, an equalized rate of data, and the like.
In a possible implementation manner, when the terminal device resides in the history resident cell, the terminal device may determine, according to a transmission condition of the service data, transmission rate information of the history resident cell during a process of transmitting the service data, and store the transmission rate information. That is, the terminal device may passively acquire the transmission rate information of the history resident cell.
In another possible implementation manner, when the terminal device resides in the history resident cell, the terminal device may actively initiate measurement of the transmission rate of the history resident cell, obtain the transmission rate information of the history resident cell according to the measurement result of the transmission rate, and store the transmission rate information. That is, the terminal device may actively measure the transmission rate information of the history of the camping cell. The 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, according to the transmission rate information of the candidate camping cells, a target cell to camp on from at least one candidate camping cell.
For example, the terminal device may determine, from the at least one candidate camped cell, a candidate camped cell with the maximum transmission rate as the target cell, and the terminal device may also determine, from the at least one candidate camped cell, a candidate camped cell with a transmission rate greater than a preset threshold as the target cell. The embodiment of the present application does not limit this.
Step 230, the terminal device executes a cell camping operation for 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, the network registration, random access and other processes can be executed, so as to realize uplink data synchronization.
Therefore, in the cell camping method provided by the embodiment of the application, the terminal device may select a cell satisfying the camping condition from the plurality of historical camping cells to obtain at least one candidate historical camping cell; after the terminal equipment determines a target cell from at least one candidate historical resident cell based on the transmission rate information corresponding to the at least one candidate historical resident cell; finally, the terminal device may perform a cell camping operation for the target cell. That is to say, according to the cell camping method provided in the embodiment of the present application, the terminal device may select a target cell from candidate camped cells that can camp on, to camp on, according to the transmission rate information of the history camped cells. Therefore, the terminal equipment can select the cell with better transmission quality to reside, so that the data transmission quality of the resident cell is improved, and the data internet experience of a user is optimized.
In some embodiments, the terminal device may store and maintain a history resident cell list, and store the related information of the plurality of history resident cells through the history resident cell list. That is, the terminal device records cell identification information, frequency band information, and center frequency point information of a plurality of history residential cells through the history residential cell list.
Therefore, the terminal equipment reads the historical resident cell list under the conditions of starting up or searching for the network again after the network is disconnected. And then, searching the historical resident cells through cell identification information, frequency band information and center frequency point information of a plurality of historical resident cells stored in the historical resident cell list to obtain a search result. And then, the terminal equipment judges whether the historical resident cells meet the resident conditions according to the search results of each historical resident cell, and selects one cell from the historical resident cells meeting the resident conditions for resident.
In some embodiments, the historical camped cell list may further store transmission rate information of each historical camped cell.
Based on this, in step 220, the terminal device determines a target cell from the at least one candidate camped cell based on the transmission rate information corresponding to the at least one candidate camped cell, including:
the terminal equipment acquires transmission rate information corresponding to at least one candidate resident cell from the historical resident cell list;
and the terminal equipment determines a target cell from the at least one candidate resident cell based on the transmission rate information corresponding to the at least one candidate resident cell.
It is to be understood that, after determining at least one candidate camping cell, the terminal device may read, from the historical camping cell list, transmission rate information corresponding to each candidate camping cell respectively. And determining a target cell to camp on from the at least one candidate camping cell based on the transmission rate information of each candidate camping cell.
In some embodiments, the plurality of historical camped cells in the historical camped cell list are ordered by a size of a transmission rate of the historical camped cell.
The plurality of history resident cells in the history resident cell list may be arranged from high to low according to the transmission rate, or may be arranged from low to high according to the transmission rate. The embodiment of the present application does not limit this.
In some embodiments, the terminal device records and maintains a list of relevant information of cells in which the terminal device resides through a history cell maintenance module of an access stratum protocol stack, and sorts a plurality of history resident cells according to transmission rate.
In some embodiments, the terminal device in step 220 may determine the target cell from the at least one candidate camped cell based on the transmission rate information corresponding to the at least one candidate camped cell, and this may be implemented by:
and the terminal equipment determines a cell with the transmission rate meeting the selection condition from the at least one candidate resident cell based on the transmission rate information corresponding to the at least one candidate resident cell to obtain the target cell.
Wherein the selection condition comprises at least one of:
the transmission rate is the cell with the maximum transmission rate in at least one candidate historical resident cell;
the transmission rate is greater than a rate threshold.
In some embodiments, in the case that the number of candidate camping cells is only one, the terminal device may directly determine the candidate camping cell as the target cell. Or, the terminal device may determine whether the transmission rate of the candidate cell is greater than a rate threshold, and if so, the terminal device determines the candidate cell as the target cell.
In some embodiments, in a case where the number of candidate camping cells includes a plurality of candidate camping cells, the terminal device may select a cell having the largest transmission rate from the plurality of candidate camping cells as the target cell to camp on, according to the transmission rate information of each candidate camping cell.
In other embodiments, when the number of candidate camping cells includes a plurality of candidate camping cells, the terminal device may select, according to the transmission rate information of each candidate camping cell, a cell with a transmission rate greater than a rate threshold from the plurality of candidate camping cells as the target cell to camp on.
Here, if the number of candidate camping cells with a 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, in a case that the number of candidate camping cells includes a plurality of candidate camping cells, the terminal device may rank the plurality of candidate camping cells according to a data transmission rate of each candidate camping cell, and attempt camping on the plurality of candidate camping cells in an order from a high transmission rate to a low transmission rate.
In some embodiments, the plurality of historical camping cells in the historical cell list maintained by the terminal device may be ordered according to transmission rate size. Therefore, the terminal equipment can directly select the cell with the minimum index number from the candidate resident cells according to the sequence of the index numbers of the candidate resident cells to be used as the target cell to be resident. Therefore, the computing resources of the electronic equipment can be saved, and the residence efficiency of the cell is improved.
In practical application, the candidate camping cell may also configure the priority order of camping. The priority order of the candidate camping cells may be related to the radio access system of the network. For example, the terminal device may preferentially access to a candidate cell camping on a 5G network, and when no cell adopting a 5G standard exists in the candidate cell camping, the terminal device may select a candidate cell camping on an LTE network.
In some embodiments, the terminal device may determine the target cell by combining the transmission rate of the candidate camping cell and the priority order of the candidate camping cell.
For example, the terminal device may preferentially select the candidate camping cells with high priority, and if the number of the candidate camping cells with high priority is multiple, the terminal device may select the candidate camping cell with the highest transmission rate from the multiple candidate camping cells with high priority as the target cell.
In an embodiment of the present application, referring to the flowchart shown in fig. 3, before the terminal device selects a cell satisfying a camping condition from a plurality of history camping cells in step 210 to obtain at least one candidate history camping cell, the following steps may be further performed:
step 202, under the condition that the terminal equipment is accessed to a first cell, acquiring transmission rate information of the first cell;
step 204, the terminal device constructs a history resident cell list based on the transmission rate information of the first cell.
The first cell is any one of a plurality of historical resident cells.
That is to say, when the terminal device camps on and accesses any one cell, the terminal device may 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, and the like.
Therefore, after acquiring the transmission rate information of the cell and other related information, the terminal device can construct a history resident cell list according to the transmission rate information and other related information of the cell, so that the terminal device can use the history resident cell list to perform cell residence when searching for a network or starting up next time.
In some embodiments, if the terminal device already stores the history camped cell list, the terminal device may update the transmission rate information of the first cell and other related information into the history camped cell list.
In some embodiments, when the terminal device updates the history resident cell list, the arrangement position of the first cell in the history resident cell list may be determined based on the transmission rate information of the first cell, so that the rate information of the history resident cell located before the first cell is smaller than the transmission rate of the first cell, and the rate information of the history resident cell located after the first cell is larger than the transmission rate of the first cell.
In some embodiments, in step 202, in the case that the terminal device accesses the first cell, acquiring the transmission rate information of the first cell may be implemented by:
step 2021, when the terminal device accesses the first cell, sending a measurement signal to the network device;
step 2022, receiving a feedback signal of the network device, and determining the transmission rate information of the first cell based on the feedback signal.
In this embodiment, when the terminal device resides in any one cell, the terminal device may actively initiate measurement of the transmission rate of the resident cell, and count at least one of an average rate, a highest rate, or an equilibrium rate over a period of time.
Specifically, the terminal device may send a measurement signal to a 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 may 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 traffic data sent by the terminal device to the network device, or may be a signal dedicated to transmission rate measurement. The embodiment of the present application does not limit this.
Therefore, when the terminal equipment is started up or network searching is carried out next time, the terminal equipment can select a target cell from the candidate resident historical cells which can be resident for resident according to the transmission rate information of the resident historical cells. Therefore, the terminal equipment can select the cell with the higher transmission rate for residing on the basis of the transmission rate, so that the transmission quality of the cell after residing is improved.
In an embodiment of the present application, an embodiment of the present application further provides a history camped cell list generation method, and referring to the flowchart shown in fig. 4, the history camped cell list generation method may include step 410 and step 420.
Step 410, under the condition that the terminal device is accessed to the first cell, acquiring transmission rate information corresponding to the first cell; the first cell is any one of a plurality of historical resident cells of the terminal equipment; the transmission rate information is used for enabling the terminal equipment to determine a target cell for executing cell residing operation from a plurality of historical residing cells;
step 420, the terminal device constructs a history resident cell list based on the transmission rate information corresponding to the first cell.
It can be understood that, when the terminal device camps on and accesses any one cell, the terminal device may 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, and the like.
Therefore, after acquiring the transmission rate information of the cell and other related information, the terminal device can construct a history resident cell list according to the transmission rate information and other related information of the cell, so that the terminal device can use the history resident cell list to perform cell residence when searching for a network or starting up next time.
In some embodiments, if the terminal device already stores the history camped cell list, the terminal device may update the transmission rate information of the first cell and other related information into the history camped cell list.
In some embodiments, when the terminal device updates the history resident cell list, the arrangement position of the first cell in the history resident cell list may be determined based on the transmission rate information of the first cell, so that the rate information of the history resident cell located before the first cell is smaller than the transmission rate of the first cell, and the rate information of the history resident cell located after the first cell is larger than the transmission rate of the first cell.
In some embodiments, when the terminal device is camped on any one cell, it may actively initiate measurement of the transmission rate of the camped cell, and count at least one of an average rate, a highest rate, or an equalized rate over a period of time.
Specifically, when accessing a first cell, a terminal device sends a measurement signal to a network device corresponding to the first cell; and the terminal equipment receives a feedback signal of the network equipment and determines the transmission rate information of the first cell based on the feedback signal.
Specifically, in this embodiment of the 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 may 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 traffic data sent by the terminal device to the network device, or may be a signal dedicated to transmission rate measurement. The embodiment of the present application does not limit this.
Therefore, in the history resident cell list generation method provided in the embodiment of the present application, the terminal device may store the transmission rate information of the cell where the terminal device resides in the history resident cell list, so that when the terminal device is powered on next time or performs network search, the terminal device may select a target cell from the candidate history resident cells that can reside to perform residence according to the transmission rate information of the history resident cell. In this way, the terminal device can select the cell with better transmission quality for camping based on the transmission rate, thereby improving the transmission quality of the cell after camping.
The cell camping method provided in the embodiment of the present application is described in detail below with reference to specific application scenarios.
Referring to the flowchart shown in fig. 5, when the terminal device resides in a cell, the terminal device may record the transmission rate information of the current cell and the related information of the current cell.
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.
Additionally, the transmission rate information for a cell includes, but is not limited to, average rate, highest rate, equalized rate over a period of time.
Further, referring to fig. 5, the terminal device may store the relevant information of the current cell into the history camped cell list according to the transmission rate information of the current cell.
Specifically, the terminal device may sort the current cell and all the historical residential cells according to the transmission rate information, determine the position of the current cell in the historical residential cell list, and store the relevant information of the current cell according to the determined position to obtain the historical residential cell list.
In some embodiments, a history cell maintenance module of an access stratum protocol stack of the terminal device records and maintains a history information list of the camped cells, and the ranking is performed according to an algorithm of data traffic rate.
Referring to the flowchart shown in fig. 6, when the terminal device is powered on or performs network search, the historical camped cell list is obtained. Further, the terminal device searches a plurality of history cells stored in the history resident cell list according to the history resident cell list, and determines candidate resident cells meeting the resident condition from the plurality of history resident cells.
And after the terminal equipment obtains the candidate resident cells, sequencing the candidate resident cells according to the transmission rate of the candidate resident cells. Further, the terminal equipment selects the cells with the optimal data rate in sequence for residing.
In this way, the terminal device may determine the target cell based on the transmission rate information, thereby obtaining a cell with the best rate in the current environment. Therefore, the data internet experience of the user is optimized from the actual needs of the user.
According to the cell residence scheme, the protocol specification of the 3GPP is optimized, and the transmission rate information of the cell is considered in one step when the cell resides, so that the cell with the optimal rate in the current environment is selected.
