Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application provides a cell search method, which is implemented by a terminal, wherein the terminal can be specifically an electronic device such as a mobile phone and a tablet computer, and the embodiment of the application is not limited. Fig. 1 is a first flowchart illustrating a cell search method according to an embodiment of the present application. As shown in fig. 1, the cell search method mainly includes the following steps:
s101, searching a second type cell based on a target frequency point searching sequence and a target searching frequency band under the condition that the duration of the idle state is greater than a first time threshold.
In the embodiment of the application, the terminal may search the second type cell based on the target frequency point search sequence and the target search frequency band when the duration of the idle state is greater than the first duration threshold.
It should be noted that, in the embodiment of the present application, the terminal is currently registered on the first cell belonging to the first type cell, and the embodiment of the present application is not limited to the specific first cell.
It should be noted that, in the embodiment of the present application, the first type cell may be a long term evolution cell, that is, an LTE cell, and the second type cell may be a non-independent network anchor cell, that is, an NSA anchor cell. Correspondingly, the first cell belongs to an LTE cell, and the terminal is currently registered with the cell.
It can be understood that, in the embodiment of the present application, the terminal is actually registered to the first cell belonging to the LTE cell, and the idle state entered is actually the LTE idle state. Further, the terminal starts timing after entering the idle state, so that after the duration of the idle state is greater than the first time threshold, the search of the NSA anchor cell is started.
It should be noted that, in the embodiment of the present application, the first duration threshold may be preset according to an actual application requirement, for example, the first duration threshold is 5 minutes. In addition, the terminal may configure a timer with a first duration threshold, so that after entering the LTE idle state, the timer is started, and after the timer expires, the search of the NSA anchor cell is triggered. The specific first time length threshold is not limited in the embodiments of the present application.
Specifically, in an embodiment of the present application, a terminal searches for a second type cell based on a target frequency point search sequence and a target search frequency band, including: sequencing the frequency points included in the target search frequency band by using the target frequency point search sequence to obtain a frequency point sequence; and searching the second type cells on the frequency points of the frequency point sequence in sequence.
It should be noted that, in the embodiment of the present application, the target frequency point search sequence may be preset according to actual requirements, and the search sequences of different types of frequency points are specified. The target search frequency band is related to a Subscriber Identity Module (SIM) card of the terminal, and is set by an operator of the SIM card. The specific target frequency point searching sequence and the target searching frequency band are not limited in the embodiment of the application.
Illustratively, in the embodiment of the present application, the target frequency point search sequence is: historical learned NSA frequency points, pre-buried NSA frequency points and other frequency points with residual frequency bands. Therefore, the terminal sequences the frequency points included in the target search frequency band according to the target frequency point search sequence, that is, the NSA frequency points belonging to historical learning in the target search frequency band are arranged at the top, the NSA frequency points belonging to pre-embedded in the target search frequency band are arranged in the middle, the NSA frequency points not belonging to historical learning in the target search frequency band nor belonging to pre-embedded NSA frequency points in the target search frequency band are arranged at the bottom, that is, the rest other frequency points in the target search frequency band are arranged at the top, and thus a frequency point sequence is obtained. The frequency points of the same type, for example, the frequency points all belonging to pre-embedded NSA, may be randomly ordered, and of course, may also be ordered according to a certain rule, without specific limitation. After the terminal obtains the frequency point sequence, further, the search of the NSA anchor point cell can be sequentially performed on the frequency points of the frequency point sequence.
It can be understood that, in the embodiment of the present application, the above-mentioned sequence of searching for the target frequency point is used, the frequency points included in the target search frequency band are firstly sequenced, and then, the search of the second type of cell is performed on the frequency points of the sequence of frequency points in sequence, which is only an exemplary implementation manner. In an actual implementation process, a target frequency point searching sequence may also be utilized, one frequency point is selected from a target searching frequency band each time, and a second type cell is searched on the selected frequency point until the whole frequency band is traversed.
S102, when a second cell belonging to a second type cell is searched, adding the second cell into a reselection list of the first cell according to a first priority; the first priority is higher than a priority corresponding to a cell in the reselection list that belongs to the first type of cell.
In the embodiment of the application, when the terminal searches for a second cell belonging to a second type cell, the second cell is added to the reselection list of the first cell according to the first priority.
It should be noted that, in the embodiment of the present application, a plurality of second cells belonging to the second type of cell, which are searched by the terminal, may be provided, that is, as long as the second cell belonging to the second type of cell is searched, the second cell is added to the reselection list of the first cell according to the first priority. The specific second cells, and the number of the second cells are not limited in the embodiments of the present application.
It should be noted that, in the embodiment of the present application, the first cell belongs to an LTE cell, and the second cell belongs to an NSA anchor cell, so that the terminal adds the second cell to a reselection list of the first cell according to the first priority, and actually establishes a current service, and a relationship between the first cell belonging to the LTE cell and a neighboring cell of the second cell belonging to the NSA anchor cell, so that when the terminal moves from an LTE coverage area to an NSA coverage area to perform cell reselection, there is a possibility of reselecting the NSA anchor cell.
Specifically, in the embodiment of the present application, before the terminal adds the second cell to the reselection list of the first cell according to the first priority, the method includes: acquiring a second priority corresponding to a cell belonging to the first type cell from the reselection list; the first priority is determined according to the second priority.
It should be noted that, in the embodiment of the present application, each cell in the reselection list is configured with a corresponding priority, where a priority corresponding to a cell belonging to the first type of cell is a second priority, and the terminal may directly acquire the second priority, and then, based on a priority configuration principle, the terminal sets a first priority, which is higher than the second priority, for a second cell belonging to the second type of cell, so as to add the second cell into the reselection list according to the first priority, that is, in the reselection list, the priority of the second cell is higher, so that when the terminal moves from an LTE coverage area to an NSA coverage area and performs cell reselection, there is a greater chance to reselect the second cell belonging to the second type of cell, so as to initiate registration.
It can be understood that, in the embodiment of the present application, the first cell belongs to an LTE cell, the second cell belongs to an NSA anchor cell, and the terminal adds the second cell into a reselection list at a priority higher than that of the LTE cell, so that when the terminal moves from an LTE coverage area to an NSA coverage area and performs cell reselection, the second cell belonging to the NSA anchor cell may be selected preferentially to initiate registration, so that, when the registration is successful, the second cell provides corresponding service, and it is avoided that the cell belonging to the LTE cell is reselected all the time to perform registration during reselection.
Fig. 2 is a flowchart illustrating a cell search method according to an embodiment of the present application. As shown in fig. 2, in the embodiment of the present application, after the terminal searches for the second type cell based on the target frequency point search sequence and the target search frequency band, that is, after step S101, the method may further include the following steps:
s201, under the condition that any cell belonging to the second type cell is not searched, after a second time length threshold value, searching the second type cell based on the target frequency point searching sequence and the target searching frequency band again.
It can be understood that, in the embodiment of the present application, the terminal may also not search any cell belonging to the NSA anchor cell after executing step S101, in this case, the terminal may wait for the second duration threshold, and perform the search of the NSA anchor cell again after the second duration threshold is ended, where a specific search manner is the same as the manner described in step S101, and is not described herein again. The second duration threshold may be greater than the first duration threshold, and is preset according to actual application requirements, for example, the second duration threshold is 30 minutes. The specific second duration threshold is not limited in the embodiments of the present application.
It should be noted that, in the embodiment of the present application, after performing the NSA anchor cell search again, the terminal may not search yet, at this time, a third duration threshold may be waited, and after the third duration threshold is ended, the search of the NSA anchor cell is performed again, and so on, and then, in the case of not searching yet, the terminal may wait for a certain duration and repeatedly perform the search until a cell belonging to the NSA anchor cell is searched, so as to add the reselection list.
Fig. 3 is a third flowchart illustrating a cell search method according to an embodiment of the present application. As shown in fig. 3, in the embodiment of the present application, after the terminal searches for the second type cell based on the target frequency point search sequence and the target search frequency band, that is, after step S101, the method may further include the following steps:
s301, when a second cell belonging to the second type cell is searched, registration is initiated to the second cell.
In the embodiment of the present application, after searching for the second cell belonging to the NSA anchor cell, the terminal may also directly initiate registration with the second cell.
It is to be understood that, in the embodiment of the present application, not only the second cell may be added to the reselection list as in step S102, but also registration may be directly initiated with the second cell. Of course, the terminal may be successfully registered or may fail to be registered. If the registration fails, the terminal waits for the second duration threshold as in step S103, and re-searches the NSA anchor cell, and if the registration succeeds, the terminal may not perform the search of the NSA anchor cell any more.
Fig. 4 is a fourth flowchart illustrating a cell search method according to an embodiment of the present application. As shown in fig. 4, in the embodiment of the present application, when the terminal searches for a second cell belonging to a second type cell, after adding the second cell to the reselection list of the first cell according to the first priority, that is, after step S102, the method may further include the following steps:
s401, under the condition that the second cell is selected from the reselection list and the registration to the second cell fails, after a third time length threshold value, searching the second type cell again based on the target frequency point searching sequence and the target searching frequency band.
In the embodiment of the application, the terminal searches the second type cell again based on the target frequency point search sequence and the target search frequency band after a third time threshold value under the condition that the terminal selects the second cell from the reselection list and fails to register to the second cell.
Specifically, in the embodiment of the present application, the terminal may configure a timer with a third duration threshold, so that when the registration with the second cell belonging to the NSA anchor cell fails, the timer is started, and after the timer is over, the search of the second type cell is triggered again. The third duration threshold may be equal to or different from the second duration threshold, and the specific third duration threshold is not limited in this embodiment of the application.
It can be understood that, in the embodiment of the present application, there may be a plurality of second cells belonging to the NSA anchor cell, and therefore, when the terminal moves from the LTE coverage area to the NSA coverage area and performs cell reselection, when selecting a second cell that is most suitable for currently performing registration, the terminal may initiate registration with the second cell, and of course, if the registration fails, it is also difficult for other second cells to perform registration actually.
It should be noted that, in the embodiment of the present application, when the terminal fails to register in the second cell belonging to the NSA anchor cell, after the third duration threshold, the process of searching the NSA anchor cell again based on the target frequency point search sequence and the target search frequency band is completely the same as the process of searching the NSA anchor cell in step S101, and details are not repeated here.
It should be noted that, in the embodiment of the present application, after reselecting and searching the NSA anchor cell, if any cell belonging to the NSA anchor cell is not searched, the terminal may re-search again after the fourth time threshold, and so on, and continuously perform periodic repeated search until the cell is searched, and then add the reselection list.
It should be noted that, in the embodiment of the present application, after the terminal adds the second cell to the reselection list of the first cell based on the priority configuration principle, that is, after step S102, the method may further include the following steps: and under the condition that the second cell is selected from the reselection list and is successfully registered to the second cell, finishing the search of the second type cell.
It can be understood that, in the embodiment of the present application, when the terminal moves from the LTE coverage area to the NSA coverage area for cell reselection, it may also successfully register to the second cell after selecting the second cell of the reselection list, that is, implement registration to the second cell belonging to the NSA anchor cell, and therefore, no search for the NSA anchor cell will be required subsequently.
