Technical Field
The present application belongs to the field of communications technologies, and in particular, to a cell reselection method, apparatus, terminal device, and storage medium.
Background
With the evolution of Dual card technology, Dual SIM Dual Active (DSDA) has been gradually supported by more terminal devices. In the DSDA mode, the dual card services in the terminal device may be concurrently ongoing, for example, the terminal card 2 may be engaged in a voice service while the terminal card 1 is engaged in a data service (e.g., gaming or video).
In the moving process, the area where the terminal device is located changes, so that the terminal device may move from the coverage of the current cell to the coverage of other cells. Therefore, when the network signal is weak, in order to ensure the quality of the network signal, the terminal card 1 or the terminal card 2 needs to perform cell reselection and switch the camping frequency point to the neighboring frequency point.
In this case, the frequency points of the dual card may be switched to an undesired frequency point combination.

Detailed Description
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, but not all, embodiments of the present application. 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 terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
As described above, in the case of cell reselection, the frequency points of the dual cards may be switched to an undesired frequency point combination. For example, when the terminal device is originally in a frequency point combination supporting DSDA and the user is performing concurrent service on the frequency point combination supporting DSDA, if the dual card is reselected by the cell and is switched to the frequency point combination not supporting DSDA, the concurrent service of the terminal device may be interrupted, thereby affecting user experience.
Generally, for the dual card service concurrency of the DSDA mode, a radio frequency path capable of concurrency is required. For example, the reception path of the terminal card 1 is concurrent with the reception path of the terminal card 2, and the transmission path of the terminal card 1 is concurrent with the transmission path of the terminal card 2. That is, the terminal device requires 2 sets of paths capable of receiving and transmitting simultaneously. Therefore, the concurrency of rf paths means that more rf devices are needed to support, resulting in higher termination costs.
The inventor has recognized during development that in some terminal devices, some of the dual-frequency-point combinations cannot support the DSDA mode in order to reduce the cost or due to the limitation of the radio frequency architecture. Therefore, if the frequency point of the dual card is switched to the frequency point combination which does not support the DSDA by the network, the interruption of the terminal service is caused, and the user experience is affected.
The cell reselection method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a flowchart illustrating a cell reselection method according to an embodiment of the present application.
The cell reselection method according to the embodiment of the application is applied to the terminal equipment comprising the first terminal card and the second terminal card. Here, the first terminal card and the second terminal card may be Subscriber Identity Module (SIM) cards.
Specifically, referring to fig. 1, the cell reselection method includes:
step S101, under the condition that a first terminal card resides at a first frequency point and a second terminal card resides at a second frequency point, measuring adjacent frequency points according to a preset priority sequence of frequency point combinations, wherein each frequency point combination comprises a third frequency point corresponding to the first terminal card and a fourth frequency point corresponding to the second terminal card;
step S102, when the signal intensity of the first terminal card at the first frequency point is lower than a preset threshold value and the signal intensity of the first terminal card at the third frequency point meets a reporting condition, the first terminal card is switched from the first frequency point to the third frequency point.
Here, the reporting condition may be that the measured signal strength of the neighboring frequency point is greater than a preset threshold, for example. Generally, after measuring that a certain frequency point combination meets a reporting condition, the terminal device may report a measurement report to the network, so that the network decides whether to instruct the terminal device to perform cell handover operation based on the measurement report reported by the terminal device.
Therefore, when cell reselection is performed, by measuring the neighboring frequency points according to the preset priority order of the frequency point combinations, the embodiment of the present application can switch the frequency point combination where the terminal card resides to the desired frequency point combination, that is, switch to the frequency point combination which is the most preferred according to the preset priority order as much as possible, thereby minimizing the problem of switching to an undesired frequency point combination due to cell reselection existing in the related art.
In addition, in some embodiments, when the signal strength of the second terminal card at the second frequency point is lower than a preset threshold and the signal strength of the second terminal card at the fourth frequency point meets the reporting condition, the second terminal card is switched from the second frequency point to the fourth frequency point. That is, when the signal strength of the frequency points where two terminal cards reside is lower than the preset threshold, both the two terminal cards can be switched.
In some embodiments, the preset priority order includes that the priority of the double-SIM card double-pass frequency point combination is higher than that of the non-double-SIM card double-pass frequency point combination. That is, the frequency point combination of the third frequency point and the fourth frequency point may be a dual-card dual-pass frequency point combination.
Specifically, in a DSDA frequency point combination or a non-DSDA frequency point combination, a priority order may also be given according to network configuration, for example, in the DSDA frequency point combination, the priority of a 5G frequency point combination may be higher than the priority of a 4G frequency point combination.
Therefore, under the condition of the preset priority sequence configuration, the frequency point combination where the terminal card resides can be switched to the double-card bi-pass frequency point combination as much as possible, so that interruption of terminal services is avoided, and user experience is improved.
In addition, in some embodiments, before measuring neighboring frequency points according to a preset priority order of frequency point combinations, the method further includes: and sequencing the adjacent frequency points configured by the network to generate a frequency point combination within the frequency point combination range supported by the terminal equipment. It should be noted that, in the embodiment of the present application, the frequency point combination is processed only by the terminal device. That is, the terminal device does not report the frequency point combination to the network. Specifically, within the frequency point combination range supported by the terminal device, the neighboring frequency points configured by the network are ordered to generate a frequency point combination, the generated frequency point combination is ordered according to a preset priority order, and then the neighboring frequency points are measured according to the preset priority order of the frequency point combination. The frequency bin combinations themselves are not reported to the network. As a result, in the embodiment of the present application, since the frequency point combination is processed only by the terminal device, there is an advantage that the adaptability is strong and network cooperation is not required. Particularly, compared with the technology requiring network coordination, the method avoids the defects of complicated process and poor adaptability, such as the coordination required by each operator network, a large number of network tests and the like when operators are crossed.
In some embodiments, in the dual-card dual-pass frequency point combination or in the non-dual-card dual-pass frequency point combination, the preset priority order may further include that the priority of the first frequency point combination is higher than that of the second frequency point combination; and in the first frequency point combination, the fourth frequency point is the same as the second frequency point, and in the second frequency point combination, the fourth frequency point is different from the second frequency point.
That is to say, when the frequency point where only one terminal card resides is weak in signal and needs to reselect a cell, the frequency point combination that only needs to switch the frequency point of one terminal card can be preferentially selected according to the preset priority order. Therefore, the priority of the first frequency point combination is higher than that of the second frequency point combination, so that under the condition of switching to the first frequency point combination, the adjacent cell measurement and switching can be carried out on the frequency point of one terminal card, and therefore the measurement and switching process is saved, the cell reselection efficiency is improved, and resources are saved.
In addition, in the case of applying the second frequency point combination, that is, in the case of applying the frequency point combination including the fourth frequency point different from the second frequency point, the second terminal card is switched from the second frequency point to the fourth frequency point regardless of whether the signal intensity of the second terminal card at the second frequency point is lower than the preset threshold. It has been described above that in some embodiments, when the signal strength of the second terminal card at the second frequency point is lower than the preset threshold, and the signal strength of the second terminal card at the fourth frequency point meets the reporting condition, the second terminal card is switched from the second frequency point to the fourth frequency point. However, the embodiment of the present application is not limited to this, because the priority of the first frequency point combination is higher than the preset priority order of the second frequency point combination, in the case that only the second frequency point combination can be applied in the dual-card dual-pass frequency point combination, it should be understood that even if the signal strength of the second terminal card at the second frequency point is equal to or higher than the preset threshold, the frequency point of the second terminal card needs to be switched. Therefore, under the condition of the preset priority sequence configuration, the frequency point combination where the terminal card resides can be switched to the double-card bi-pass frequency point combination as much as possible, so that interruption of terminal services is avoided, and user experience is improved.
It should be noted that, according to the cell reselection method in the embodiment of the present application, the execution subject may be the terminal device, or may also be a functional module and/or a functional entity in the terminal device, which is used for executing the cell reselection method.
A cell reselection method according to an embodiment of the present application will be described in detail below with reference to fig. 2 and 3, taking as an example that both the first terminal card and the second terminal card (hereinafter also referred to as card 1 and card 2) are in a connected state and thus the terminal device is in a DSDA mode. The card 1 network and the card 2 network may be network devices of an operator, such as base stations, among others.
Fig. 2 is a schematic diagram of a specific implementation procedure according to an embodiment of the present application.
Referring to fig. 2, both card 1 and card 2 are in a connected state and thus the terminal device is in a DSDA mode. For example, card 1 may reside at frequency point X and card 2 may reside at frequency point y. The bin combination X, y is a DSDA bin combination.
The following description will be made in the case where the frequency bin where only one card resides is weak. Specifically, a case where the frequency point signal where the card 1 resides is weak and the frequency point signal where the card 2 resides is weak will be described as an example.
Under the condition that the frequency point signal resided in the card 1 is weak and the frequency point signal resided in the card 2 is not weak, the card 1 network configures a measurement object for the card 1, wherein the measurement object comprises a plurality of neighboring frequency points for reselection.
And then, the terminal equipment measures the adjacent frequency points according to the preset priority sequence of the frequency point combination. Table 1 illustrates a plurality of frequency point combinations, i.e., combination 1 to combination 7, according to an embodiment of the present application. Each frequency point combination includes a third frequency point corresponding to the card 1 and a fourth frequency point corresponding to the card 2, for example, the combination 1 includes a frequency point X corresponding to the card 1 and a frequency point y corresponding to the card 2. Here, the frequency point corresponding to the card 1 in each frequency point combination is within the range of the multiple reselectable neighboring frequency points configured for the card 1 by the card 1 network. In table 1, combinations 1 to 7 are ordered in a preset priority order. That is, combination 1 has the highest priority, combination 2 has the next highest priority, and combination 7 has the lowest priority. Among the frequency bin combinations, combinations 1 to 5 may be DSDA frequency bin combinations, and combinations 6 to 7 may be non-DSDA frequency bin combinations. That is, DSDA bin combinations have higher priority than non-DSDA bin combinations. In addition, combinations 1 to 3 are DSDA frequency point combinations in which the frequency point y of the card 2 is the same as the frequency point y where the card 2 resides, and combinations 4 to 5 are DSDA frequency point combinations in which the frequency point corresponding to the card 1 and the frequency point corresponding to the card 2 are different from the frequency points where the card 1 and the card 2 reside. As shown in table 1, the priority of combination 1 to combination 3 is higher than that of combination 4 to combination 5.
TABLE 1
| Frequency point combination | Card 1 | Card 2 |
| Combination 1 | X | y |
| Combination 2 | B | y |
| Combination 3 | C | y |
| Combination 4 | A | b |
| Combination 5 | C | c |
| Combination 6 | D | y |
| Combination 7 | D | f |
And according to the priority of the preset priority sequence, the terminal equipment preferentially measures the frequency point B corresponding to the card 1 in the combination 2. If the signal strength of the card 1 at the frequency point B meets the reporting condition, the terminal equipment reports the corresponding measurement event, and then switches the frequency point X where the card 1 resides to the frequency point B. Since the combination 2 is also a DSDA frequency point combination, the problem of switching to a non-DSDA frequency point combination due to cell reselection is avoided.
In addition, if the signal strength of the card 1 at the frequency point B does not meet the reporting condition, the terminal device continues to perform the measurement of the frequency point C corresponding to the card 1 in the combination 3 according to the priority of the preset priority order. If the signal strength of the card 1 at the frequency point C meets the reporting condition, the terminal device reports the corresponding measurement event, and then switches the frequency point X where the card 1 resides to the frequency point C. Since the combination 3 is also a DSDA frequency point combination, the problem of switching to a non-DSDA frequency point combination due to cell reselection is avoided.
However, if the signal strength of the frequency point C of the card 1 does not satisfy the reporting condition, that is, when the DSDA frequency point combination that the frequency point corresponding to the card 2 is the same as the frequency point where the card 2 resides is unavailable, other DSDA frequency point combinations, such as combination 4 and combination 5, are continuously measured according to the priority of the preset priority order. Here, the combinations 2 and 3 are first frequency bin combinations, and the combinations 4 and 5 are second frequency bin combinations.
As shown in fig. 2, according to the measurement object configured by the card 2 network, the cards 1 and 2 may be switched to the combination 4 or the combination 5 according to the priority of the preset priority order under the condition that the reporting condition is satisfied. Therefore, as shown in fig. 2, the frequency points of both the card 1 and the card 2 are switched. That is, in the case of applying the second frequency point combination such as combination 4, combination 5, the frequency point of the card 2 needs to be switched regardless of whether the signal intensity of the card 2 at the second frequency point is lower than the preset threshold. Since the combination 4 and the combination 5 are both DSDA frequency point combinations, the problem of switching to non-DSDA frequency point combinations due to cell reselection is avoided.
However, if neither combination 4 nor combination 5 satisfies the reporting condition, combination 6 and combination 7 are considered in accordance with the priority of the preset priority order. The frequency point D corresponding to the card 1 in the combination 6 and the combination 7 is the neighboring frequency point with the strongest signal. The frequency point corresponding to the card 2 in the combination 6 is the same as the frequency point where the card 2 resides, so that when the combination 6 meets the reporting condition, as shown by the arrow on the left side in fig. 2, only the frequency point of the card 1 can be switched. It should be understood that although combination 6 is shown in table 1 as having a higher priority than combination 7, combination 6 may not be considered, and combination 7 may be preferred among non-DSDA combinations, depending on the actual situation. The frequency point D corresponding to the card 1 and the frequency point f corresponding to the card 2 in the combination 7 may be neighboring frequency points with strongest signals of the card 1 and the card 2, respectively.
Furthermore, it should be understood that the generated frequency bin combinations are not fixed, which depends on the measurement objects of the network configuration. Alternatively, the combinations 1 to 7 may be continuously generated from the measurement results. For example, DSDA combinations 1 to 3 are first generated from the measurement object of the card 1 network configuration. And under the condition that the DSDA combinations 1 to 3 do not meet the reporting condition, generating a DSDA combination 4 and a DSDA combination 5 according to the measurement object configured by the card 2 network. If the DSDA combination 4 and the combination 5 do not meet the reporting condition, a non-DSDA combination 6 is generated. And if the non-DSDA combination 6 also meets the reporting condition, generating a non-DSDA combination 7.
In addition, the above examples are described only in terms of possible cases, however, in actual cases, there may be only one or some cases of the combinations 1 to 7 depending on the network and the terminal device.
Fig. 3 is a schematic diagram of another specific implementation flow according to an embodiment of the present application.
Referring to fig. 3, both card 1 and card 2 are in the connected state and the terminal device is in the DSDA mode. For example, card 1 may reside at frequency point X and card 2 may reside at frequency point y. The bin combination X, y is a DSDA bin combination.
The following description will be made in a case where the frequency point signals where 2 cards reside are weak. The frequency point signals of the cards 1 and 2 are weak, so as shown in fig. 3, the card 1 network and the card 2 network respectively configure the card 1 and the card 2 with measurement objects containing a plurality of neighboring frequency points for reselection.
And the terminal equipment measures the adjacent frequency points according to the preset priority sequence of the frequency point combination. The preset priority order is similar to that of fig. 2, and is not described herein again to avoid repetition.
The above has been described based on the case where both the card 1 and the card 2 are in the connected state. It should be understood that the case where one of the cards 1 and 2 is in the connected state and the other card is in the idle state, and the case where both the cards 1 and 2 are in the idle state may also perform a cell reselection method similar to the case where both the cards 1 and 2 are in the connected state.
In some embodiments, for a case where one of the cards 1 and 2 is in a connected state and the other card is in an idle state, if the frequency point signals where the 2 cards reside are weak, when implementing the cell reselection method, it may be considered that the priority of the handover of the card in the connected state is set to be higher than the priority of the handover of the card in the idle state in a preset priority order. In so doing, it is possible to preferentially secure the traffic of the card in the connected state. Since the card in the idle state does not perform a service, it does not bring about a bad user experience.
