Detailed Description
The technical solutions of the present application will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
At the present stage, the 5G network can significantly improve the network rate, and when the network and the mobile phone support 5G, the 5G network is preferentially registered to provide better experience for the user, and the 4G network cannot provide faster network rate for the user, which affects the user experience. At present, because the coverage area of a 5G base station is relatively small, the stations are distributed more densely, a 4G base station and a 5G base station coexist in the same place, and not all 4G networks support the 5G network, which may cause that a terminal may not register 5G in an environment with the 5G network or the rate of registering 5G is very slow, thereby affecting user experience.
Based on this, the embodiment of the application provides a method and an apparatus for preferentially registering a 5G network, and a mobile terminal, so that the mobile terminal preferentially registers the 5G network in an environment where a 4G network and the 5G network coexist, and a user obtains better network experience.
For the convenience of understanding the present embodiment, a detailed description will be first given of a cell reselection control method disclosed in the present embodiment.
An embodiment of the present application provides a method for preferentially registering a 5G network, where the method is applicable to an environment where a 4G network and a 5G network coexist, an execution subject of the method is a mobile terminal, and referring to fig. 1, a flowchart of the method for preferentially registering a 5G network provided in the embodiment of the present application is specifically included in the following steps:
step S102, a plurality of candidate 4G cells corresponding to the mobile terminal are searched.
In specific implementation, a mobile terminal is used for network search, so that a plurality of candidate 4G cells can be searched, and generally, the number of candidate 4G cells is not more than 10.
And step S104, sequentially judging whether the target candidate 4G cells exist in the candidate 4G cells or not based on the analysis information of the system messages of the candidate 4G cells. The target candidate 4G cell meets the preset cell access condition, and the corresponding system message comprises the cell of the specified IE; wherein IE is designated as a parameter for characterizing the support of 5 GNR.
In this step, the system message of the candidate 4G cell is first analyzed, and the determination is performed through the information analyzed from the system message, generally speaking, the analysis of the system message of the 4G cell may obtain: MIB, SIB1, SIB2 and SIB3-SIB13. Here, it is determined whether three system messages of MIB, SIB1, SIB2 are needed for the target candidate 4G cell.
Specifically, it is first determined whether the first candidate 4G cell is a cell that not only satisfies a preset cell access condition, but also includes a specified IE. If not, continuing to judge the next candidate 4G cell, and if so, performing 5G network connection based on the current candidate 4G cell. The cell access condition is the content in the 3GPP protocol, which is the prior art and is not described herein again. The above-mentioned IE (Information Element) is a parameter that can characterize the support of 5 GNRs. Specific IEs are as follows:
plmn-InfoList-r15；
{
{
upperLayerIndication-r15 true；
}
{
upperLayerIndication-r15 true；
}
}
if the target candidate 4G cell exists, step S106 is executed to initiate 4G network registration so that the mobile terminal is connected with the 5G network supported by the target candidate 4G cell.
Through the judgment, once a certain candidate 4G cell is judged to be a cell which not only meets the preset cell access condition but also comprises the specified IE, namely the target candidate 4G cell, 4G network registration is further initiated, so that the mobile terminal is connected to the 5G network supported by the target candidate 4G cell.
If the target candidate 4G cell does not exist, step S108 is executed to perform 4G network connection based on the cell satisfying the cell access condition among the candidate 4G cells.
That is, if there is no target candidate 4G cell meeting the condition after the determination is completed for all of the candidate 4G cells, at this time, the 4G network connection may be performed according to a cell meeting the cell access condition among the candidate 4G cells.
In the method for preferentially registering the 5G network provided by the embodiment of the application, a plurality of candidate 4G cells corresponding to the mobile terminal are searched firstly; whether a target candidate 4G cell exists in the candidate 4G cells is sequentially judged based on the analysis information of the system messages of the candidate 4G cells; the target candidate 4G cell is a cell which meets the preset cell access condition and the corresponding system message of which comprises the specified IE; wherein IE is designated as a parameter for characterizing the support of 5 GNR; if the target candidate 4G cell exists, initiating 4G network registration to enable the mobile terminal to be connected with a 5G network supported by the target candidate 4G cell; and if the target candidate 4G cell does not exist, performing 4G network connection based on the cell meeting the cell access condition in the candidate 4G cells. By the method, the mobile terminal can preferentially register the 5G network in the environment where the 4G network and the 5G network coexist, so that a user can obtain better network experience.
For the analysis information of the system message based on the candidate 4G cells, the step of sequentially judging whether the target candidate 4G cell exists in the candidate 4G cells has two implementation manners:
the first method comprises the following steps:
(1) The first candidate 4G cell is taken as the first current candidate cell.
(2) For each first current candidate cell, performing the steps of: and judging whether the first current candidate cell meets the cell access condition or not according to the MIB and the SIB1 in the system message of the first current candidate cell, and judging whether the SIB2 in the system message of the first current candidate cell comprises the specified IE or not.
The MIB for analyzing the system message can acquire frame synchronization with the 4G cell, and the SIB1 for analyzing can acquire scheduling information of other system messages, so that other system messages can be analyzed on the corresponding frame, therefore, the MIB and the SIB1 in the system message are analyzed first, whether the first current candidate cell meets the cell access condition is judged according to the two messages, and then whether the appointed IE is included is judged according to the analyzed SIB 2.
(3) And if the judgment results are yes, determining the first current candidate cell as the target candidate 4G cell.
(4) And if at least one judgment result is negative, taking the next candidate 4G cell as the first current candidate cell until the candidate 4G cell is traversed.
If the candidate 4G cells are completely traversed and the two conditions are not met, it may be determined that the target candidate 4G cell does not exist in the candidate 4G cells, and the preferential connection of the 5G network cannot be performed, in which case, the 4G network connection may only be performed. The specific target candidate 4G cell determination process can be seen in fig. 2.
And the second method comprises the following steps:
(1) And sequentially searching candidate 4G cells meeting the cell access condition from the candidate 4G cells based on the MIB and the SIB1 in the system messages of the candidate 4G cells.
(2) Taking the first candidate 4G cell meeting the cell access condition as a second current candidate cell, and executing the following steps for each second current candidate cell: it is determined whether SIB2 in the system message of the second current candidate cell includes the specified IE.
(3) And if the judgment result is yes, determining the second current candidate cell as the target candidate 4G cell.
(4) And if the judgment result is negative, taking the next candidate 4G cell meeting the cell access condition as a second current candidate cell until the candidate 4G cell meeting the cell access condition is traversed.
The method comprises the steps of finding out cells meeting cell access conditions from a plurality of candidate 4G cells, then further judging whether the SIB2 of each selected cell comprises specified IE, namely whether 5G network connection is supported or not, if all the cells meeting the cell access conditions are traversed, the cells not supporting the 5G network connection are not available, and 4G network connection can be carried out only based on the cells meeting the cell access conditions.
In the above embodiment, the step of sequentially searching for a candidate 4G cell satisfying the cell access condition from the multiple candidate 4G cells based on the MIB and the SIB1 in the system message of the multiple candidate 4G cells specifically includes the following steps:
(1) The first candidate 4G cell is taken as the third current candidate cell.
(2) For each third current candidate cell, performing the following steps: and according to the MIB and the SIB1 in the system message of the third current candidate cell, judging whether the third current candidate cell meets the cell access condition.
(3) And if so, determining the third current candidate cell as a candidate 4G cell meeting the cell access condition.
(4) And if the judgment result is negative, taking the next candidate 4G cell as a third current candidate cell until the candidate 4G cell is traversed.

In the 4G network connection process, that is, based on the candidate 4G cells satisfying the cell access condition among the plurality of candidate 4G cells, the step of performing 4G network connection is implemented by the following method:
according to a preset cell selection rule, the first candidate 4G cell meeting the cell access condition in the plurality of candidate 4G cells is used as a service cell of the mobile terminal, so that the mobile terminal and the base station establish 4G network connection.
After the network connection, the mobile terminal may further perform a cell reselection process according to a cell reselection parameter obtained in real time, that is, after the step of initiating 4G network registration to enable the mobile terminal to connect to a 5G network supported by a target candidate 4G cell, the method further includes the following steps, as shown in fig. 3:
step S302, resolving SIB3-SIB13 in the system message of the target candidate 4G cell to obtain cell reselection parameters.
