Background

At present, most mobile terminals (such as mobile phones) support to insert two SIM (Subscriber Identity Module) cards, namely a user identification card, and are respectively called a main card and a sub card, wherein when the mobile terminal is on the internet, the main card is generally selected to carry services, and the sub card is generally only used for carrying basic services such as telephone, short messages and the like. Taking the secondary card as an example, the RRC connection state of the secondary card may be divided into an idle state and a connected state according to whether an RRC (radio resource control) connection is established, when the secondary card is in the idle state, standby power consumption is low, and when the secondary card establishes an RRC connection to enter the connected state, standby power consumption may increase, so if the secondary card frequently establishes an RRC connection, standby power consumption may increase.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

It should be noted that, all actions of acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

First, an application scenario of the present disclosure is described, where the present disclosure is mainly applied to a scenario of detecting an RRC connection state of a target subscriber identity card (i.e., a SIM card) on a terminal, for example, the target subscriber identity card may be a secondary card.

Taking the auxiliary card as an example, the auxiliary card monitors paging messages broadcasted by the network in standby, and if the paging messages sent to the auxiliary card exist in the paging messages, the auxiliary card establishes RRC connection. In general, if the secondary card receives the paging message and establishes the RRC connection, it needs to receive a short message or a phone in the RRC connection state, where the RRC connection established in this case belongs to a normal connection, but because a network may be abnormal, after the secondary card establishes the RRC connection, no short message or phone is sent to the secondary card, and the paging message received by the secondary card and unrelated to the short message and the incoming call is garbage paging. When the auxiliary card establishes the RRC connection and enters a connection state, the standby power consumption can be increased, so if the auxiliary card frequently establishes the RRC connection due to frequent garbage paging, the standby power consumption can be increased, and on the other hand, the auxiliary card also can occupy the RRC resource of the main card when establishing the RRC connection, and the data service of the main card can be influenced.

The problem of garbage paging exists when the auxiliary card can only use the 4G network, and with the continuous development of the 5G network technology, the auxiliary card can also use the 5G network, and the problem of standby power consumption increase caused by frequent establishment of RRC connection of the auxiliary card due to garbage paging is particularly serious in the scene that the auxiliary card uses the 5G network in both double cards because the power consumption of the 5G network is generally higher than that of the 4G network.

Aiming at the problem of power consumption increase caused by the establishment of the RRC connection, a method for releasing the RRC connection as soon as possible after the establishment of the RRC connection is considered in the related art. For example, after the RRC connection is established, a timer is set, and if no valid uplink and downlink data packet is detected during the timer, the RRC connection is actively released after the timer expires, which has the following drawbacks from the viewpoint of shortening the duration of time that the RRC is in the connected state: the auxiliary card RRC connection establishment behavior caused by garbage paging cannot be fundamentally avoided; since the timer is set after the RRC connection is established to detect that no uplink and downlink data packet will release the RRC connection within a period of time, during the operation of the timer, additional power consumption and the problem of influencing the data service of the main card will be caused by the establishment of the RRC connection by the sub-card.

In order to solve the above-mentioned existing problems, the present disclosure provides a method, an apparatus, a storage medium and a chip for triggering cell switching, which can first determine whether an RRC connection currently established by a target subscriber identity card belongs to an abnormal connection, and trigger the target subscriber identity card to switch from a current residence cell to a target cell under the condition of determining that the RRC connection belongs to the abnormal connection, so that the target subscriber identity card can deviate from the current residence cell, and thus has a chance of no longer receiving a garbage page, thereby avoiding the abnormal situation that an RRC frequently establishes a connection due to garbage paging, further saving power consumption caused by frequently establishing the RRC connection, and if the target subscriber identity card is a secondary card, further avoiding the problem that a data service of a primary card is affected due to frequent establishment of the RRC connection by the secondary card.

The following detailed description of specific embodiments of the present disclosure refers to the accompanying drawings.

Fig. 1 is a flowchart illustrating a method of triggering a cell handover, as shown in fig. 1, for use in a terminal (e.g., a handset), according to an exemplary embodiment, comprising the following steps.

In step S11, a radio resource management RRC connection state of the target user identification card on the terminal is acquired.

The target subscriber identity card includes a SIM card, and the target subscriber identity card may be any subscriber identity card on the terminal, for example, the current mobile phone generally supports a dual-card mode, and in the case that two SIM cards (one is a main card and one is a sub card) are installed on the mobile phone, the target subscriber identity card may be a sub card. The RRC connection state may include an idle state or a connected state, and as described above, when the target subscriber identity card monitors a paging message addressed to itself, RRC connection is established, and when RRC connection is not established, the RRC connection state is the idle state.

In step S12, if it is determined that the RRC connection state changes, it is determined whether the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection according to the change of the RRC connection state.

In one possible implementation manner, the RRC connection state may be recorded by a preset flag bit, for example, when the preset flag bit is 1, the RRC connection state is represented as a connected state, and when the preset flag bit is 0, the RRC connection state is represented as an idle state, so that whether the RRC connection state is changed can be determined according to whether the data corresponding to the preset flag bit is changed.

In determining whether the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection, in one possible implementation manner, the occurrence time of the RRC connection state change may be determined, where the occurrence time includes a first time when the RRC connection state transitions from the idle state to the connection state and a second time when the RRC connection state transitions from the connection state to the idle state, where the first time is a time when the RRC connection state transitions from the idle state to the connection state.

In the above-mentioned practical application scenario, the RRC connection established under the condition that the target subscriber identity card needs to receive the sms or the phone belongs to the normal connection, but if the target subscriber identity card establishes the RRC connection, no sms or phone is sent to the target subscriber identity card, and the currently established RRC connection is the abnormal connection.

In step S13, in the case that it is determined that the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection, the target subscriber identity card is triggered to switch from the current camping cell to the target cell.

In this step, the target user identification card may be triggered to switch from the current residence cell to the target cell, so that the target user identification card may not receive the garbage page any more, and thus the abnormal condition that the RRC frequently establishes connection due to the garbage page is avoided.

In addition, in consideration of the normal standby state of the terminal, the communication network of the low network system is selected for communication, and compared with the communication network of the high network system, the power consumption is lower, so that the network system of the target cell can be lower than the network system of the current resident cell in order to save the power consumption.

By adopting the method, firstly, whether the RRC connection currently established by the target user identification card belongs to abnormal connection is judged, and under the condition that the RRC connection is determined to belong to the abnormal connection, the target user identification card is triggered to switch from the current residence cell to the target cell, so that the target user identification card can be separated from the current residence cell, and the garbage paging can be avoided, the abnormal condition that the RRC connection is frequently established due to the garbage paging can be avoided, the power consumption caused by the frequent establishment of the RRC connection can be further saved, and the problem that the data service of the main card is influenced because the RRC connection is frequently established by the auxiliary card can be avoided if the target user identification card is the auxiliary card.

In one possible implementation, the target subscriber identity card may be triggered to switch from the currently camped cell to the target cell by modifying the network type of the target subscriber identity card.

Fig. 2 is a flowchart illustrating a method of step S13 according to an exemplary embodiment, and as shown in fig. 2, the target subscriber identity card may be triggered to switch from the currently camped cell to the target cell by the following steps.

In step S131, the current network system of the target user identification card is acquired.

For example, the current network system may include any one of SA and NSA 5G networking modes, or LTE (Long Term Evolution ), or a 3G network system.

In step S132, a first network selection mode is determined according to the current network system.

The network selection mode is used to characterize the network type selection priority of the target subscriber identity card, for example, one possible network selection mode may be 5G priority, and another possible network selection mode may be 4G priority. The first network selection mode refers to a network selection mode (i.e., a modified network selection mode) that needs to be modified in order to trigger the target subscriber identity card to perform cell handover, and in one possible implementation manner, a corresponding relationship between a current network system and the first network selection mode may be preset, and then the first network selection mode corresponding to the current network system is determined according to the corresponding relationship.

For example, if the current network system is an SA network, since the SA network belongs to a 5G network system, the network selection mode may be modified to be 4G-preferred in order to trigger the target subscriber identity card to perform cell handover, and thus, if the current network system is an SA network, the first network selection mode may be 4G-preferred, which is only illustrated herein, and the disclosure is not limited thereto.

In step S133, the network selection mode of the target subscriber identity card is modified from the second network selection mode at the current time to the first network selection mode.

It should be understood that, in one possible implementation, the first network selection mode and the second network selection mode are different network selection modes, and in consideration of that the communication network of the low network system is selected for communication in the normal standby state of the terminal, the first network selection mode may be 4G preferred if the second network selection mode is 4G preferred, for example, the first network selection mode may be 3G preferred if the second network selection mode is 4G preferred, and therefore, when the network system of the SIM card of the mobile phone is switched from 5G to 4G, the SIM card may obtain a partial power consumption benefit, so that in order to save power consumption, the network system with the highest selection priority in the first network selection mode is generally lower than the network with the highest selection priority in the second network selection mode, for example, if the second network selection mode is 5G preferred, the first network selection mode may be 4G preferred, and if the second network selection mode is 4G preferred, the first network selection mode may be 3G preferred, which is not limited herein.

In addition, in order to further save power consumption, in the case of modifying the network selection mode of the target subscriber identity card from the second network selection mode at the current time to the first network selection mode, the modification may not be reported to the AP (Application Processor ) of the terminal, so that the AP may be prevented from being awakened, and thus power consumption due to the awakening of the AP may be saved.

In step S134, the target subscriber identity card is triggered to switch from the currently camping cell to the target cell according to the first network selection mode.

For example, if the current network system of the target subscriber identity card is the SA network in the 5G networking mode, the current network selection mode (i.e., the second network selection mode) of the target subscriber identity card is usually 5G-preferred, and in this network selection mode, the current residence cell is the cell of the target subscriber identity card corresponding to the 5G network service selected by the network selection mode according to the 5G-preferred network selection mode, in order to trigger the target subscriber identity card to perform cell switching, the network selection mode may be modified to be 4G-preferred, so that the target subscriber identity card may be triggered to perform cell switching based on the network selection mode with the 4G-preferred network selection mode, and the cell is switched to the serving cell corresponding to the 4G network service (i.e., the target cell).

By adopting the method, under the condition that the RRC connection established by the target user identification card currently belongs to abnormal connection, the target user identification card can be triggered to switch from the current residence cell to the target cell by modifying the network selection mode of the target user identification card, and the network system of the target cell can be lower than that of the current residence cell, so that the opportunity is not needed to receive garbage paging, the abnormal condition that the RRC connection is frequently established due to garbage paging is avoided, and the power consumption can be saved by reducing the network system of the target user identification card.

In another possible implementation, the handover of the target subscriber identity card from the currently camping cell to the target cell may also be triggered by: and after the current resident cell is added into a preset cell list, triggering the target user identification card to be switched from the current resident cell to the target cell, wherein the preset cell list is a cell list representing resident cells which cannot be used as the target user identification card. That is, the target subscriber identity card may be triggered to perform cell switching by adding the current resident cell to the preset cell list, and the duration of adding the current resident cell to the preset cell list may be set, for example, after adding the current resident cell to the preset cell list for a single hour, the current resident cell may be deleted from the preset cell list, so that under the condition that the network of the current resident cell is recovered to be normal, the initial network system may be recovered in time, and the communication quality of the target subscriber identity card may be ensured.

In yet another possible implementation manner, in the case that the current network system of the target subscriber identity card is determined to be the specified network system, the target subscriber identity card may also be triggered to switch from the current resident cell to the target cell by closing the current network system, for example, the specified network system may be an NSA network.

It should be noted that, after the target subscriber identity card is triggered to perform cell switching based on the above condition, the specific implementation manner of cell switching may refer to the description in the related art, which is not limited herein, and the disclosure only describes the triggering condition (i.e. the embodiment corresponding to fig. 2, the manner of adding the current resident cell to the preset cell list, or the manner of closing the current network system) for triggering the target subscriber identity card to perform cell switching.

Fig. 3 is a flow chart illustrating a method of triggering a cell handover according to the embodiment shown in fig. 1, the method further comprising the steps of:

in step S14, in the case that the target trigger event is determined to occur, the terminal is controlled to execute the preset recovery operation, so that the terminal recovers the initial network system of the target subscriber identity module card.

Wherein the target trigger event may include at least one of the following events:

The target user identification card is changed;

triggering the execution time of cell switching to be larger than or equal to a preset time threshold;

the current communication service of the target subscriber identity card is abnormal.

As mentioned above, after cell handover, in order to save power consumption, the network system of the target cell may be lower than the network system of the current resident cell, but it is well known that the communication quality of the high network system is generally better than the low network system, so that in case that any of the above target trigger events is determined to occur, the initial network system of the target subscriber identity card may be recovered in time.

For example, assuming that after the target subscriber identity card performs cell switching, it is switched from the 5G cell (i.e., the currently camping cell) to the 4G cell (i.e., the target cell), it is obvious that the communication quality of the 4G cell is lower than that of the 5G cell, and therefore, in case that it is determined that any of the above-mentioned target trigger events occurs, the preset recovery operation may be performed, so that the terminal recovers the initial network system (i.e., the 5G network) of the target subscriber identity card.

In a possible application scenario, a user may actively switch between a main card and a sub card, if the target user identification card is a sub card, after the user switches between the main card and the sub card, that is, the sub card is switched into the main card, the target user identification card is changed, and it can be understood that in this case, the initial network system of the target user identification card needs to be restored in time by executing a preset restoration operation, so as to ensure the communication quality of the user identification card.

In addition, considering that the phenomenon that the user identification card receives the garbage page due to the network abnormality may belong to a transient problem at present, in order to timely recover the initial network system after the network of the current resident cell is normal, a timing function of triggering the execution time of the action may be set, and when it is determined that the execution time of triggering the cell switch is greater than or equal to a preset time threshold, the initial network system of the target user identification card may be timely recovered by executing a preset recovery operation.

In another possible application scenario, after triggering the cell handover, the user may manually modify the network system of the target user identification card, for example, after performing the cell handover, the network system of the target user identification card is changed to a 4G network, but when detecting that the current network system is 5G, it indicates that the user may actively modify the network system, so that in the case of determining that the current network system of the target user identification card is changed from the first system to the second system, the original network system of the target user identification card needs to be restored, for example, the first network system is a 4G network, and the second system is a 5G network.

In yet another possible application scenario, in the case where the current communication service of the target subscriber identity card is abnormal (e.g., no service or limited service), it is also necessary to restore the original network system of the target subscriber identity card in order to ensure the communication quality.

In addition, in one implementation, the preset recovery operation herein may specifically be: the network selection mode of the target user identification card is modified from the first network selection mode to the second network selection mode, that is, the target user identification card can be restored to the original network system by modifying the network selection mode to the original network selection mode.

Therefore, the present disclosure may record the network selection mode (i.e., the second network selection mode) before the modification of the target subscriber identity card before triggering the cell handover by modifying the network selection mode, so that it is convenient to modify the network selection mode of the target subscriber identity card from the first network selection mode to the recorded second network selection mode when performing the preset recovery operation.

In another implementation manner, if the cell switching is triggered by adding the current resident cell to a preset cell list, the preset recovery operation may be to delete the current resident cell from the preset cell list, so that when the target subscriber identity card performs cell reselection or cell switching, the current resident cell may be used as a serving cell again, so that the initial network system of the target subscriber identity card may be recovered.

When determining whether the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection, the present disclosure determines through the recorded RRC hopping number (which will be described in detail below), so the preset recovery operation may further include clearing the RRC hopping number, even if the RRC hopping number is zero.

In addition, when judging whether to trigger the handover action of the target subscriber identity card from the current residence cell to the target cell, a handover action flag bit may be set, for example, when the handover action flag bit is 1, it indicates that the handover action has been triggered, and when the handover action flag bit is 0, it indicates that the handover action has not been triggered.

The above detailed description describes how to trigger the target subscriber identity card to switch from the current resident cell to the target cell under the condition that it is determined that the RRC connection currently established by the target subscriber identity card belongs to the abnormal connection, and how to recover the initial network system of the target subscriber identity card after the action of triggering the cell switch, and the detailed implementation manner of determining whether the RRC connection currently established belongs to the abnormal connection is described below.

In one possible implementation manner, whether the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection may be determined according to an occurrence time of the connection state change.

Fig. 4 is a flowchart illustrating a method of step S12, according to an exemplary embodiment, as shown in fig. 4, the method comprising the steps of:

in step S121, a state change type of the RRC connection state at the current time is determined.

The state change type may include a change type in which the RRC connection state transitions from an idle state to a connection state, or a change type in which the RRC connection state transitions from a connection state to an idle state.

In step S122, the target number of hops of the RRC is determined according to the state change type, the first time and the second time.

The first time refers to a time when the RRC connection state jumps from the idle state to the connection state, the second time refers to a time when the RRC connection state jumps from the connection state to the idle state, the target number of hops is used to characterize the number of times that the target subscriber identity card recorded at the current time establishes the RRC connection, and it can be understood that a situation where the target number of hops is higher in a certain time may be regarded as that the RRC frequently establishes the connection.

In this step, in the case that the state change type is determined to be a jump from the idle state to the connected state, determining a first duration in which the RRC is in the idle state according to the first time and the second time; and accumulating the RRC hopping times according to the preset times when the first duration is smaller than or equal to the preset idle state minimum duration, so as to obtain the target hopping times.

For example, fig. 5 is a schematic diagram illustrating an RRC connection state according to an exemplary embodiment, where, as shown in fig. 5, the RRC connection state of the target subscriber identity card is hopped from an idle state to a connection state, denoted as an event a, the RRC connection state of the target subscriber identity card is hopped from a connection state to an idle state, denoted as an event B, as shown in fig. 5, events a and B alternate, where A1, A2, A3 represent a first time, B1, B2, B3 represent a second time, and when the current time is A2 time (i.e., the first time), the RRC connection state of the target subscriber identity card is hopped from the idle state to the connection state at a time A2, and when the last hop time adjacent to the time A2 is a time B1 (i.e., the second time), such that A2-B1 represents a first duration in which the RRC is in the idle state, if A2-B1 is less than or equal to the preset minimum duration of idle state (may be denoted as Timer 1), it may be stated to a certain extent that the current time RRC connection state transitions from idle state to connection state and belongs to abnormal transition, in this case, the RRC transition times may be accumulated according to the preset time variation range (for example, 1 time) to obtain the target transition times, so after the RRC transition times are accumulated once, whether the target transition times are greater than or equal to the preset time threshold may be determined, and in the case that the target transition times are greater than or equal to the preset time threshold, it is determined that the RRC connection currently established by the target user identification card belongs to abnormal connection.

In addition, when the first duration is greater than or equal to the preset maximum duration of the idle state (which may be denoted as Timer 2), it is indicated that the RRC is stable in the idle state, and the RRC connection state transitions from the idle state to the connection state at the current time, which belongs to normal transitions, and the target number of transitions may be cleared.

When the state change type is determined to jump from the connection state to the idle state, determining a second duration of time that the RRC is in the connection state according to the first time and the second time; and under the condition that the second duration is greater than or equal to the preset maximum duration of the connection state, the RRC is stabilized in the connection state, and the target jump times can be cleared to ensure the normal operation of the current communication service of the target user identification card.

For example, taking fig. 5 as an example, taking the current time as the B1 time as an example, as shown in fig. 5, the RRC connection state transitions from the connection state to the idle state at the B1 time, and B1-A1 is the second duration, and when it is determined that B1-A1 is greater than or equal to the preset connection state maximum duration (which may be denoted as Timer 3), it is indicated that the RRC is stable in the connection state, and the target transition number may be cleared.

The target jump frequency can be determined based on the method.

In step S123, if the target hop frequency is greater than or equal to the preset frequency threshold, it is determined that the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection.

It can be understood that, when the target hopping number is determined to be greater than or equal to the preset number threshold, it can be stated that the target subscriber identity card frequently establishes an RRC connection, and it can be further determined that the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection.

In another possible implementation manner, whether the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection may be determined according to the number of times of change of the RRC connection state in a preset period of time, where the number of times of change generally refers to the number of times of RRC connection establishment (i.e., the number of times that the RRC connection state changes from an idle state to a connected state), and it may be understood that, in the preset period of time, if the number of times of change is greater than or equal to a preset number of times threshold, it may be determined that the RRC connection currently established by the target subscriber identity card belongs to an abnormal connection.

It should be noted that, in an actual application scenario, regarding to a main card and an auxiliary card on a terminal, considering that the main card carries a terminal internet service in addition to basic phone and short message service, for the main card, it is possible for the main card to frequently establish RRC connection to belong to normal service requirements, but for the auxiliary card, in an actual service scenario, the auxiliary card usually only carries basic services such as phone, short message, etc., and in the case that no short message or phone is sent to the auxiliary card, the RRC connection established by the paging message received by the auxiliary card and irrelevant to the short message and the incoming call belongs to abnormal connection, so in the present disclosure, if the target subscriber identification card is the main card of the terminal, it is possible not to perform processing, that is, whether the RRC connection currently established by the main card belongs to abnormal connection is not judged; in addition, even if the target user identification card belongs to the auxiliary card, the auxiliary card does not process when the auxiliary card is carrying out short message and call service; considering that if the current network system of the sub-card belongs to a specific network system (such as 2G and 3G) with a lower network system, because the current lower network system is mainly used for bearing basic communication services such as short messages, telephones and the like, if the current network system of the sub-card belongs to the specific network system, whether the RRC connection currently established by the target user identification card belongs to abnormal connection is not judged.

By adopting the method, whether the RRC connection currently established by the target user identification card belongs to abnormal connection can be accurately judged according to the state change type of the RRC connection state at the current moment and the change of the RRC connection state, and under the condition that the RRC connection belongs to the abnormal connection is determined, the target user identification card is triggered to switch from the current residence cell to the target cell, so that the target user identification card can be separated from the current residence cell, and the opportunity is avoided from receiving the garbage paging, thereby avoiding the abnormal condition that the RRC connection is frequently established due to the garbage paging, further saving the power consumption caused by frequently establishing the RRC connection, and further avoiding the problem that the data service of the main card is influenced by frequently establishing the RRC connection by the auxiliary card if the target user identification card is the auxiliary card.
