Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The architecture of the current 5G network is mainly Option3a and Option3x, that is, 5G coverage is deployed on a 4G anchor cell, and in order to make users perceive 5G coverage, an indication, that is, a network signal indication in common, needs to be provided on a terminal. An alternative is two solutions proposed by the GSMA organization, where the first is to display the 5G icon only when the terminal is connected to the 5G network, and the remaining cases are to display the 4G icon. The disadvantages of this solution are:

1, the 5G network in an idle state cannot be reflected; 2, the probability of displaying 5G is low, and 5G is not publicized by an operator; the 3G, 5G icons and the 4G icons are more alternated, so that the complaint probability of the user on the 5G network coverage is high.

The second solution is to display a 5G icon whenever the terminal detects an NSA network. The disadvantages of this solution are: if not really connected to the 5G resource while connected, in some rate sensitive scenarios, the user may feel the rate is low, thereby complaining the operator of false promotions.

How to timely and effectively show the real coverage condition of the network to the user and improve the perception and experience value of the user on the 5G network is the problem to be solved by the invention.

Fig. 1 is a schematic flow chart of a signal display method according to an embodiment of the present application, including:

and S1, searching the resident 4G cell according to the terminal network parameters and residing in the 4G cell.

S2, in case that a 5G network is deployed in the resident 4G cell, measuring the signal strength of the 5G cell in the resident 4G cell, and selecting the 5G cell with the strongest signal.

And S3, displaying the signal information of the resident 4G cell and the signal information of the selected 5G cell.

Specifically, in step S1, after the terminal is powered on, the stored necessary information is read, where the necessary information includes a mobile network (PLMN) list, information of a last-camped 4G cell, and frequency band information corresponding to the PLMN information.

If the terminal does not reside in the cell for the first time, the terminal must store the cell information which resides when the terminal is powered off last time, preferentially searches the cell which resides last time, directly selects the cell if the cell is available, searches again if the cell is not searched or the cell is unavailable, and resides after finding a proper cell.

As shown in fig. 2, when the terminal first camps on the cell, the stored necessary information is read, where the PLMN information and the corresponding frequency band information are shown in table 1 below:

table 1: PLMN and corresponding frequency band information

The table 1 stores the supportable frequency band information corresponding to each supported PLMN network, and the supportable frequency band information is stored in the terminal in advance, and can be dynamically maintained and updated in the later use process. The purpose of this table is to avoid full frequency band search and speed up the network searching process.

For example, in this embodiment, the PLMN network to be attached is china unicom (460/01), and the current 4G cell can be camped when the 4G cell where the terminal is located includes one of the above frequency bands, only by searching the frequency bands B1/B3/B8/B34/B39/B40/B41. It should be noted that, the table also includes the 5G frequency bands supported by the PLMN network, but here, only the 4G network is attached, and only the 4G frequency bands need to be searched. The 5G band information is used in the subsequent embodiments.

For step S2, as shown in fig. 3, after finding a suitable 4G cell, it is determined whether the 4G cell is a 4G anchor cell, i.e., contains a 5G network. In this embodiment, the determination is made by analyzing the value of the parameter upperlayerindication-r15 in the 4G camping cell downlink system message. That is, the uplink-r 15 is true, indicating that the attached cell is a 4G anchor cell, including a 5G network. Otherwise, without the 5G network, the appropriate 4G cell will be reselected.

After finding that the cell where the terminal resides is a 4G anchor cell, the terminal searches for local configuration information first, as shown in table 2 below:

4G cell information	5G cell information
		Cell 1	Cell a
Cell 2	Cell b
		…	…

Table 2: last resident cell correspondence table

Table 2 shows information of the camped 4G cell and the corresponding available 5G cell stored in the terminal, and this table is dynamically maintained and is empty at the beginning.

And S21, when the 5G network is detected, searching the 5G cell information corresponding to the 4G cell stored by the terminal, and if so, selecting the 5G cell.

Specifically, if the terminal does not reside in the current 4G anchor cell for the first time, the information of the cell that resides last time is preferentially searched locally, if so, the cell can be directly selected for attachment, and if not, the cell is searched again in the initial network searching manner. The method in the above embodiment is utilized to determine whether the 4G cell includes a 5G network, and if so, then query the local table 2 whether there is corresponding 5G cell information, because the current 4G anchor cell is not camped on for the first time, there may be corresponding 5G cell information already in the table 2, query the table 2, find the corresponding 5G cell information, and directly select the 5G cell for signal measurement. If the corresponding 5G cell information is not found, searching is performed according to the 5G frequency point supported by the network according to the network finding process of residing the current 4G anchor point cell for the first time in the above embodiment.

And S22, if the 5G cell information corresponding to the 4G cell is not stored, searching and selecting the 5G cell with the strongest signal according to the 5G frequency points supported by the terminal, wherein the currently residing 4G cell and the corresponding 5G cell information are stored.

Specifically, if the terminal is the current 4G anchor cell that resides for the first time, and the 5G cell information corresponding to the resident 4G cell is not stored locally, the terminal searches according to the 5G frequency points supported by the home network, where the 5G frequency bands supported by each PLMN network are obtained in table 1 in the above embodiment. In this embodiment, china unicom (460/01) is taken as an example, the corresponding 5G frequency band information is N41/N78, 5G cells meeting the conditions are searched and screened on the frequency band, the signal strength of the 5G cells is measured respectively, a 5G cell with the strongest signal in the network is found, the 5G cell and the corresponding 4G cell information are stored in table 2, and periodic measurement is performed at the same time.

In addition, in the above embodiment, after the suitable 4G cell is attached, or the location of the terminal is changed and resides in the new 4G cell again, it is necessary to detect whether the new 4G cell deploys the 5G network again, as shown in S51 of fig. 5, reselect the new 4G cell, and detect whether the residing 4G cell deploys the 5G network again, and if the 5G signal is not detected yet, directly display the result, and remove the 5G signal on the display interface. If it is detected that the newly-resided 4G cell includes a 5G network, it indicates that the 4G cell is a 4G anchor cell, and the terminal first queries in the local table 2 whether there is corresponding 5G cell information. If the 4G anchor cell is not camped for the first time, there may be already corresponding 5G cell information in table 2. If so, the signal of the cell is measured directly. And if not, searching according to the 5G frequency points supported by the network in the same process of first network searching.

As shown in S52 of fig. 5, if the 4G anchor cell is camped for the first time, the lookup table 2 does not have corresponding 5G cell information, and a 5G cell with the strongest signal in the local network is found according to the initial network finding manner and the measurement comparison on the 5G effective frequency supported by the local PLMN.

If the existing 5G cell in table 2 is selected in the above embodiment, it is determined whether the 5G cell signal satisfies the reselection principle, and if not, the cell is selected. And if so, performing reselection, wherein the specific reselection process is as follows:

as shown in fig. 4, S41 detects the signal strength of the 5G cell corresponding to the currently camped 4G anchor cell, and detects the signal strength of other 5G cells when the signal strength is not greater than the set signal strength threshold.

Specifically, an S criterion is adopted to determine whether a 5G cell corresponding to a currently camped 4G anchor cell meets a reselection principle. Firstly, the signal strength of the 5G cell corresponding to the currently camped 4G cell is detected, and referring to the S criterion, Srxlev ═ Qrxlevmeas- (qRxLevMin + qrxlevminiffset) -pCompensation, that is, the S cell selection received signal strength value ═ RSRP (received signal level value) of the measurement cell — { lowest received level (in this embodiment, — 128dbm) + lowest received level offset (in this embodiment, 0dbm) } -power compensation (in this embodiment, 0 dbm). So, S-Qrxlevmeas +128dbm (decibel), the S value is Srxlev (S-criteria) in cell selection.

If the S value of the current 5G cell is less than or equal to Sintrasearch (same frequency measurement starting threshold), the terminal detects the signal intensity of other 5G cells with the same frequency as the current 5G cell;

and if the S value of the current 5G cell is less than or equal to Snonintrasearch (pilot frequency/pilot system measurement starting threshold), the terminal detects the signal strength of other 5G cells pilot frequency with the current 5G cell.

Taking Sintrasearch as 34dbm in this embodiment, when the RSRP of the current 5G cell is less than or equal to-94 dbm according to the calculated formula S as Qrxlevmeas +128dbm (decibel), the terminal detects the signal strength of other 5G cells with the same frequency as the current 5G cell;

and taking the Snonintrasearch as 18dbm, and detecting the signal intensity of other 5G cells different in frequency with the current 5G cell by the terminal when the RSRP of the current 5G cell is less than or equal to-110 dbm according to the calculation.

And judging whether the current resident 5G cell accords with a reselection principle or not according to the method.

And S42, when the signal strength of the target 5G cell is detected to be continuously higher than the signal strength of the current resident 5G cell by a set value within the preset time, reselecting the target 5G cell as the 5G cell with the strongest signal.

Specifically, the R criterion is adopted to determine whether to reselect the target cell for continuous measurement and reporting.

The R criterion is that the target cell is within Treselection time (reselection time parameter, Treselection of same frequency and different frequency may be different), Rt (target cell) continuously exceeds Rs (current cell), and then the terminal reselects to the target cell.

Rt＝Qmeas,t–Qoffset

Rs＝Qmeas,s+Qhyst

Wherein Qmeas, t is the RSRP value of the target cell, Qoffset is the offset value, and this embodiment is taken as 0 dbm. Qmeas, s is the RSRP value of the current cell, Qhyst is the reselection hysteresis value, which is taken as 2dbm in this embodiment.

Namely, when the RSRP value of the target cell continuously exceeds the current cell by 2db within the given reselection time, the target cell is reselected for measurement and reporting.

And after judging that the reselection condition is met, reselecting a new cell to perform continuous measurement and displaying again. The information of the 4G cell and the corresponding 5G cell in table 2 are updated simultaneously.

For the update of table 2, table 2 exists for the purpose of quickly finding the corresponding 5G cell, so the size of the table and the validity of the data are very important. The description is divided into several cases: as shown in fig. 6, at S61, the cell information stored in the terminal is sorted according to time priority, where the last use time of the cell information stored at the earlier position is shorter than the current time.

Specifically, if the table record is empty, only the currently camped 4G cell and the corresponding 5G cell information need to be inserted into the first row of the table. Ensuring next best look-up.

If the 4G cell and the corresponding 5G cell recorded in the table are valid, only this piece of information needs to be moved to the first row of the table. Ensuring next best look-up. Of course, if the current record itself is already on the first line, no further movement is required.

And S62, when the change of the 5G cell information corresponding to the 4G cell stored in the terminal is detected, updating the corresponding 5G cell information and arranging the information at the top.

Specifically, if it is detected that the 5G cell corresponding to the 4G cell camped this time is different from the 5G cell corresponding to the 4G cell recorded in the table, the corresponding 5G cell information is updated, the corresponding cell information recorded in the table is replaced with the cell information camped this time, and then the information is moved to the first row of the table. Ensuring next best look-up. Of course, if the current record itself is already on the first line, no further movement is required.

In addition, to ensure the efficiency of the search, the table cannot be infinitely large. The embodiment is defined as 5000 rows, that is, only 5000 corresponding relations of 4G cells and 5G cells are reserved at most. With the above algorithm, the most common cell information will be maintained at the front of the table, and less common ones will be ranked at the back of the table, until more than 5000, the ranked at the back will be removed.

For step S3, after the appropriate 4G cell and the corresponding 5G cell are camped, the information of the camped cell is saved in table 2, and after the saving is finished, the signal of the current camped cell is periodically measured and the corresponding network identifier is continuously displayed in a refreshing manner on the terminal interface, as shown in fig. 7, S71, if the current camped cell only includes the 4G network, the 4G network identifier is displayed, that is, the current 4G cell is not the 4G anchor cell and does not include the 5G network, and the identifier only displays the 4G network identifier (as shown in fig. 8 a).

If the current camping cell is a 4G anchor cell but has no 5G coverage, that is, the cell includes a 5G network but has very weak signals, and when the 5G cell signal is less than or equal to-123 dBm, the identifier is as shown in fig. 8b, and the 5G signal shows zero cells.

S72, if the stored signal information includes a 4G network and a 5G network, displaying the 4G network identifier and the 5G network identifier at the same time, that is, the current cell is a 4G anchor cell and has 5G coverage, and when both the 4G signal and the 5G signal are greater than-97 dbm, the identifiers are as shown in fig. 8 c.

The identification information disclosed in the present application includes, but is not limited to, the network identifiers described in the above embodiments, and those skilled in the art may easily think of the corresponding network identifiers in other cases according to the situations described in the embodiments.

Wherein, different signal intensity ranges in the above identifiers correspond to network identifiers of different styles.

In the embodiment, the 5G network signal condition can be displayed accurately and truly, the perception and satisfaction of the user to the 5G network are enhanced, and the propaganda strength of the operator to the 5G network is improved.

As shown in fig. 9, the present application also provides a signal display device including:

the judging module compares the signal intensity of the current resident 5G cell with a set signal intensity threshold, if the signal intensity of the current resident 5G cell is not greater than the set signal intensity threshold, the comparing result is fed back to the 5G network searching module, and the 5G network searching module detects the signal intensity of other 5G cells;

the judging module is further configured to compare the signal strengths of the currently camped 5G cell and the target 5G cell, and when the signal strength of the target 5G cell is continuously higher than the signal strength of the currently camped 5G cell by a set value within a preset time, feed back the comparison result to the 5G network searching module, and the 5G network searching module reselects the target 5G cell as the 5G cell with the strongest signal.

In this embodiment, the terminal is a mobile terminal, which is also called a mobile communication terminal, and refers to a computer device that can be used in mobile, including a mobile phone, a notebook computer, a tablet computer, a POS machine, a vehicle-mounted computer, and the like. But in most cases refers to smart phones and tablet computers with multiple application functions. In specific implementation, before the device leaves factory, the PLMN lists and the corresponding frequency band information parameters corresponding to all the base stations may be stored in the database.

In the embodiment, the terminal equipment can accurately display the 5G network signal condition in real time, the perception and satisfaction of the user to the 5G network are enhanced, the propaganda strength of the operator to the 5G network is improved, and the user complaint risk under excessive propaganda is avoided.
