Description

Information processing method, related device and computer program

The present application claims priority of chinese patent application with application number 201710213962.9, entitled "network searching method and device for dual card dual standby mobile phone" filed in 2017 on 1/4, and the entire contents of the application are incorporated by reference.

Technical Field

The present application relates to the field of mobile terminals, and in particular, to an information processing method, related devices, and a computer program.

Background

The multi-card multi-Standby mobile terminal refers to a mobile terminal into which a plurality of SIM cards can be inserted, and the SIM cards can be in a Standby state at the same time, and common multi-card multi-Standby mobile terminals include Dual SIM Dual Standby (DSDS) mobile terminals. The SIM card is a short name of Subscriber Identity Module (SIM), and is also called as a Subscriber Identity Module (SIM), a smart card, and the like. The meaning that multiple SIM cards are in the standby state at the same time is that multiple SIM cards are in the usable state at the same time, or are in the on state at the same time, but some SIM cards are not in the usable state or the on state, and other SIM cards are not in the usable state or the off state.

In the prior art, when a plurality of SIM card systems are all in a standby state, the systems work independently, that is, each SIM card interacts with other components or devices independently. However, when the information that needs to be obtained by multiple SIM cards is the same, the independent operation obviously causes a problem of large power consumption of the mobile terminal.

Taking the dual-card dual-standby Mobile terminal as an example, after the user starts up, the two SIM cards perform Network searching operation respectively, that is, each SIM card selects a Public Land Mobile Network (PLMN for short) and a cell. The selection of the PLMNs may be performed within the mobile terminal, and the PLMN is ranked according to the priority of the PLMNs, and then the first N PLMNs with higher priorities are selected, where N may be greater than or equal to 1. After determining the PLMN, respectively measuring the signal intensity of each frequency point of the peripheral cells through the communication with the surrounding base stations, wherein the frequency points belong to the determined PLMN, and selecting a proper cell from the frequency points for residing. Because each SIM card needs to acquire PLMN information stored in the mobile terminal and needs to measure signal strength information of each frequency point of the peripheral cell, if these information are the same for the two SIM cards, it obviously consumes too much resources of the mobile terminal to acquire them respectively.

Detailed Description

The embodiment of the application provides a network information processing method, a device, equipment and a storage medium of a multi-card multi-standby mobile terminal, which are used for solving the problem that in the prior art, when network information required to be acquired by a plurality of SIM cards is the same, the power consumption of the mobile terminal is higher. The technical solution provided in this embodiment is described below by taking a dual-card dual-standby mobile terminal as an example.

In this embodiment, the dual-card dual-standby mobile terminal may include a first SIM card system and a second SIM card system, where the SIM card system is a system including a SIM card, a signal transmitting terminal, a signal receiving terminal, a processor, a memory, and other components. The first SIM card system comprises a first SIM card, a first signal transmitting end, a first signal receiving end, a first processor and a first memory; the second SIM card system comprises a second SIM card, a second signal transmitting end, a second signal receiving end, a second processor and a second memory. The two SIM cards can be selected by a user, wherein one SIM card is used as a main card, and the other SIM card is used as a secondary card. The first signal transmitting terminal and the second signal transmitting terminal are used for transmitting signals to the base station; the first signal receiving end and the second signal receiving end are used for receiving signals sent by the base station.

In a first SIM card system and a second SIM card system in a current dual-card dual-standby mobile terminal, the method may include: the signal transmitting terminal comprises a signal receiving terminal and a signal transmitting terminal, two signal receiving terminals and a signal transmitting terminal, a signal receiving terminal and two signal transmitting terminals, or two signal receiving terminals and two signal transmitting terminals. That is, the first SIM card and the second SIM card may share one transmitting end or receiving end, or may have their own transmitting end or receiving end.

The first memory is used for storing a first program, and the first processor performs the following operations when executing the first program: and after the first SIM card system acquires the network information required for executing the network communication event, executing the network communication event according to the network information, and storing the network information in the storage unit.

The second memory is used for storing a second program, and the second processor performs the following operations when executing the second program: when the second SIM card system needs to execute the network communication event, the second SIM card system executes the network communication event by using the network information stored in the storage unit.

The storage unit may be a part of the first memory or the second memory, or may be another memory.

The first processor and the second processor may be the same processor or different processors; the first memory and the second memory may be the same memory or different memories. The first Processor and the second Processor may be a Central Processing Unit (CPU), or may be a combination of a GPU, a Digital Signal Processor (DSP), and a control chip (e.g., a baseband chip) in the communication Unit. The first Memory, the second Memory, and the storage unit may be a volatile Memory, such as a Nonvolatile dynamic Random Access Memory (NVRAM), a Phase Change Random Access Memory (PRAM), a Magnetoresistive Random Access Memory (MRAM), or the like, or a non-volatile Memory, such as at least one magnetic disk Memory device, an Electrically Erasable Programmable Read-Only Memory (EEPROM), a flash Memory device, such as a NOR flash Memory (NOR flash Memory) or a NAND flash Memory (NAND flash Memory).

In this embodiment, when the network communication event executed by the first SIM card system is the same as the network communication event executed by the second SIM card system, and the network information required to be acquired by the first SIM card system to execute the network communication event is the same as the network information required to be acquired by the second SIM card to execute the network communication event, the network information acquired by the first SIM card system to execute the network communication event may be shared with the second SIM card system. That is to say, before the second SIM card system executes the network communication event, the first SIM card system already stores the network information required for executing the network communication event in the storage unit, so that the second SIM card system does not need to acquire the network information again, and only needs to extract the network information from the storage unit for execution, thereby reducing the power consumption of the dual-card dual-standby mobile terminal and improving the processing efficiency of the network communication event.

Referring to fig. 1, the figure is a flowchart of a network information processing method of a multi-card multi-standby mobile terminal according to this embodiment.

The network information processing method of the multi-card multi-standby mobile terminal provided by the embodiment comprises the following steps:

s101: the first SIM card system acquires network information required for executing the network communication event, executes the network communication event according to the network information, and stores the network information.

S102: and when the second SIM card system needs to execute the network communication event, the second SIM card system executes the network communication event by utilizing the stored network information.

The network communication event refers to an event that network communication occurs between the multi-card multi-standby mobile terminal and the base station. The network communication event can be startup network searching, network disconnection re-searching, cell reselection, network connection state switching, paging message monitoring and the like.

As described above, in this embodiment, when the network communication event executed by the first SIM card system is the same as the network communication event executed by the second SIM card system, the network information acquired by the first SIM card system for executing the network communication event may be shared with the second SIM card system. The network information refers to information in a network communication process.

The network communication event is introduced below with reference to two application scenarios: the first SIM card and the second SIM card belong to the same operator; the first SIM card and the second SIM card belong to different operators.

Before specifically describing these network traffic events, the operator, the camping network information, the cell search information, and the camping cell information are described first.

An operator refers to a network service provider, such as mobile, unicom, telecom, etc. Each SIM card generally belongs to only one operator. The operator may identify the user equipment according to information such as an International Mobile Subscriber Identity (IMSI), a local public land mobile network (HPLMN), and an equivalent home network (EHPLMN). For example, the fourth digit and the fifth digit of the IMSI are a Mobile Network Code (MNC), the MNC of telecommunications is 03, the MNC of mobile is 00, and the MNC of connectivity is 01. Generally, after the first SIM card and the second SIM card are installed in the multi-card multi-standby mobile terminal, the operator may be read by a processor in the multi-card multi-standby mobile terminal.

In practical applications, whether the operator to which the first SIM card belongs and the operator to which the second SIM card belongs are the same may be determined according to the above-mentioned information. For example, the first SIM card and the second SIM card may read their IMSIs, and extract their MNCs from the IMSIs, and if the MNC corresponding to the first SIM card is 03 and the MNC corresponding to the second SIM card is 00, the two cards are not considered to belong to the same operator; and if the MNC corresponding to the second SIM card is 03, the second SIM card and the MNC belong to the same operator. Of course, the numbering determination of the MNCs by different operators requires reference to the allocation rules of the local networks.

The resident network information refers to information of a network where the SIM card system can reside, including supported network formats, supported frequency points, and the like, which can be read after the SIM card is installed in the multi-card multi-standby mobile terminal. The network System refers to a type of a certain generation network, such as 2G GSM (global System for Mobile communication), 4G LTE, 3G UMTS (Universal Mobile Telecommunications System), 2G CDMA (code division multiple access), and the like. If the operator to which the first SIM card belongs and the operator to which the second SIM card belongs are the same, the network systems supported by the first SIM card and the second SIM card may be the same or different. If the network systems supported by the two SIM cards are the same, the supported frequency points are also the same; if the supported network systems are different, the supported frequency points are also different.

The cell search information refers to that the SIM card searches a cell according to frequency points supported by the mobile terminal in a network searching stage to acquire cell signal intensity information and cell frequency point information. And in the same cell, the frequency points corresponding to the same operator are the same. Usually, the frequency point of one operator in one cell is usually one.

The resident cell information refers to information of a cell in which the SIM card resides. After the cell search information is acquired, a proper cell is selected according to a certain rule for residing. The information of the camping cell includes, for example, the signal strength of the camping cell, the frequency point of the camping cell, and the like.

Next, network communication events and shared network information are introduced for the case where the first SIM card and the second SIM card belong to the same operator.

1. Starting up searching net

The starting network searching refers to the network searching operation of the multi-card multi-standby mobile terminal after starting, and the network searching operation is generally performed automatically without user confirmation. As noted in the background, a network search operation typically requires selection of a PLMN and a cell.

As mentioned above, the PLMN refers to a public land Mobile Network, which corresponds to MCC (Mobile Country Code) plus MNC (Mobile Network Code). An operator in a country typically has only one PLMN, for example, the PLMN in china mobile is 46000, and the PLMN in china unicom is 46001, where 46 stands for china, 000 stands for mobile, and 001 stands for unicom.

For a particular mobile terminal, it is often necessary to maintain several different types of PLMN lists, each of which may have multiple PLMNs. These PLMN lists include, for example, RPLMN (Registered PLMN), EPLMN (Equivalent PLMN), EHPLMN (Equivalent Home PLMN), HPLMN (Home PLMN ), VPLMN (Visited PLMN), and the like. Each PLMN list has a corresponding priority, and when selecting a PLMN, the selection is performed according to the priority order of the list. The procedure for selection was as follows: the mobile terminal searches the cells according to the frequency points supported by the mobile terminal, finds the cell with the strongest signal on each frequency point, then reads the system information of the cell and determines the PLMN corresponding to the cell. And if the mobile terminal determines a plurality of PLMNs according to the frequency points supported by the mobile terminal, selecting one PLMN according to preset conditions to finish the selection of the PLMN.

Since the PLMN represents the operator, if the operators to which the first SIM card and the second SIM card belong are the same, the PLMN selected by the first SIM card system is the same as the PLMN selected by the second SIM card system, and thus the PLMN selected by the first SIM card system can be stored, so that the second SIM card system does not need to perform an action of PLMN selection, but can directly use the stored PLMN as the PLMN selected by itself.

After selecting a suitable PLMN, the mobile terminal needs to perform cell selection based on the cell signal strength information searched during cell search, and the purpose of the cell selection is to select the cell with the best signal in the PLMN for camping.

From the protocol level, a non-access stratum (NAS) performs a storage operation, and an Access Stratum (AS) performs an operation of selecting a PLMN and a cell.

Under the condition that the operator to which the first SIM card belongs is the same as the operator to which the second SIM card belongs, if the network systems supported by the first SIM card and the second SIM card are the same, the supported frequency points are also the same. When the cell is searched, because the search is performed based on the frequency points, if the frequency points supported by the two SIM cards are the same, the cell information obtained by the two SIM cards in the cell search process, including the cell signal strength information and the cell frequency point information, are the same. Therefore, the first SIM card can store the acquired cell information when performing cell search, so that the second SIM card can select a cell by using the stored cell information without performing a cell search operation again, and then camp on a suitable cell.

The network information required by the mobile terminal when executing the startup network searching comprises: the selected PLMN in the PLMN selection process, the resident cell information and/or the cell information obtained in the cell search process.

2. Broken network re-searching

The network disconnection and re-search refers to a process that when the SIM card cannot communicate with the originally connected base station for some reasons, the SIM card is connected with the network again.

The network-breaking re-search can be divided into two scenes, wherein one scene is that the first SIM card is in a network, and the second SIM card is in a network-breaking state; another scenario is that both the first SIM card and the second SIM card are disconnected. The latter scenario is basically the same as the scenario of starting up the network search, and is not described herein again. For the former scenario, if the cells where the first SIM card and the second SIM card reside at the power-on network searching stage are the same, the cell where the first SIM card resides at this time may be selected to reside after the second SIM card is disconnected. When the second SIM card system is disconnected, the cell where the first SIM card system resides may not be in accordance with the resident cell information stored when the second SIM card system is started, so that the first SIM card system can be immediately informed to store the cell information of the current resident cell after the second SIM card system is disconnected. Or, a mode of periodically storing the cell information of the current resident cell of the first SIM card system may be adopted, so as to achieve the purpose of networking in time after the second SIM card system is disconnected.

If the first SIM card and the second SIM card reside in different cells at the network searching stage, the first SIM card and the second SIM card belong to the same operator and have the same network system, the second SIM card may reside in the cell where the first SIM card resides currently, or the second SIM card performs cell selection again by using the cell information acquired at the network searching stage. And if the cell information acquired by starting up the network searching cannot be matched with the current position of the second SIM card, carrying out cell searching based on the frequency points supported by the second SIM card.

And if the first SIM card and the second SIM card belong to the same operator and the network systems are different, the second SIM card carries out cell search again.

The network information required by the mobile terminal when the network breaking re-search is executed comprises: and cell information and/or resident cell information acquired in the cell searching process.

3. Cell reselection

Cell reselection refers to reselection of a cell. Triggering cell reselection generally includes two cases, one is cell reselection performed when the first SIM card system and the second SIM card system are both in a connected state with the base station, but do not have any signal mutual transmission with the base station, that is, when the first SIM card system and the second SIM card system are in an idle state. The other is that the multi-card multi-standby mobile terminal continuously changes the received signal strength of the cell along with the movement of the user, when the user moves to the edge of the cell, the signal attenuation is serious, and when the attenuation degree is large enough, the operation of cell reselection is triggered.

The cell reselection is basically the same as the cell selection in the starting network searching stage. If the operator to which the first SIM card belongs is the same as the operator to which the second SIM card belongs and the network systems supported by the two are also the same, the second SIM card may perform cell selection and camp on using the cell information obtained by the first SIM card when searching for a cell, or camp directly on the cell where the first SIM card resides.

The network information required by the mobile terminal when performing cell reselection includes: and cell information and/or resident cell information acquired in the cell searching process.

4. Network connection state switching

The network connection state switching and the cell reselection are different in that: the network connection state switching is cell selection when the multi-card multi-standby mobile terminal is in a connection state, and the cell reselection is cell selection in an idle state.

Specifically, when the first SIM card system receives measurement control information (measurement control message) corresponding to the first SIM card system, which is sent by the base station, the cell is measured, that is, the signal strength and the frequency point of the cell are measured, and the cell measurement information is reported to the base station. After receiving the measurement report, the base station may issue a connection reconfiguration message (connection reconfiguration message) to the multi-card multi-standby mobile terminal. After receiving the connection reconfiguration message, the first SIM card system performs a network handover operation, i.e. resides in a cell corresponding to the reconfiguration message, to implement handover of the resident cell, and stores cell measurement information (i.e. cell information obtained by searching the cell).

If the operators of the first SIM card and the second SIM card are the same and the network systems of the first SIM card and the second SIM card are the same, the second SIM card system does not need to execute the same cell measurement operation, only needs to report pre-stored cell measurement information to the base station, and then waits for the base station to determine whether to perform switching operation. And if the switching operation is required, the first SIM card system receives the reconfiguration message issued by the base station, and resides in the cell corresponding to the reconfiguration message to complete resident cell switching.

If the operators of the first SIM card and the second SIM card are the same and the network systems of the first SIM card and the second SIM card are different, the second SIM card needs to perform cell measurement independently.

The network information required by the mobile terminal when performing the network connection state switching comprises: and cell information acquired in the cell search process.

5. Paging message monitoring

The embodiment is applicable to the application scenarios of network searching, and also applicable to the application scenarios of non-network searching, such as paging message monitoring. The paging message (paging message) refers to a message sent by the mobile services switching center to the mobile terminal through the base station during the paging process, and is intended to search for the mobile terminal within a certain range. For the mobile terminal, it is necessary to monitor the paging message, so that the response can be given in time when the paging message is received.

The mobile terminal can monitor the paging message from the operator to which the mobile terminal belongs, and the paging message corresponds to the SIM card. In this embodiment, the first SIM card system monitors the paging message, and responds in time if the paging message related to the first SIM card system is monitored. If the first SIM card and the second SIM card belong to the same operator, when the first SIM card system monitors the paging message corresponding to the second SIM card system, the paging message may be stored, and the second SIM card system is notified to respond according to the paging message.

The network information required by the mobile terminal when performing paging message monitoring includes: a paging message.

In summary, when the operators to which the first SIM card and the second SIM card belong are the same, whether the network information is directly stored or not is determined according to the network communication event.

If the network communication event comprises paging message monitoring, directly storing the network information when the operator of the first SIM card is the same as the operator of the second SIM card.

If the network communication event includes network starting and searching, network breaking and re-searching, cell reselection and/or network connection state switching, if the operator to which the first SIM card belongs is the same as the operator to which the second SIM card belongs, it is also necessary to determine whether the resident network information of the first SIM card system is the same as the resident network information of the second SIM card system, and if so, the network information is stored.

The above description is of the case where the operators to which the first SIM card and the second SIM card belong are the same, and in this case, the network information that can be shared by the first SIM card system and the second SIM card system is rich, including the selected PLMN in the PLMN selection process, the cell information acquired in the cell search process, the cell information of camping, and the paging message.

When the operators of the first SIM card and the second SIM card are different, the network information that can be shared is limited, and the sharing scenarios are fewer. For example, in the cell search process, if the frequency point corresponding to the PLMN selected by the first SIM card system is found to be inconsistent with the searched cell frequency point, the PLMN is reselected, and this mode becomes an out of service (OOS) mode.

When the first SIM card system and the second SIM card system are both in the OOS mode, the first SIM card system needs to search for a network in a full frequency band, and at this time, the first SIM card can store cell information obtained in the network searching process, so that the second SIM card system can perform cell selection according to the cell information. In order to improve the efficiency of cell selection by the second SIM card system, it is possible to start with cell information stored by the first SIM card, i.e. not storing cell information that may not be applicable by the second SIM card system. For example, when it is determined that a certain cell is not applicable to the first SIM card system, since the operator to which the first SIM card belongs and the operator to which the second SIM card belongs are different, the cell may support the operator to which the second SIM card belongs, and at this time, the cell information of the cell may be stored, so that the second SIM card performs cell selection according to the cell information. Further, the first SIM card system may determine whether the cell is suitable for the second SIM card according to the operator to which the second SIM card belongs and the network type of the second SIM card, and if so, store the cell information of the cell, so that the second SIM card system may camp on the cell according to the cell information. The cell information of the cell needing to be screened when the second SIM card system selects the cell is reduced, and the cell selection efficiency of the second SIM card system is improved.

In addition, some network standards provide that after a certain frequency point matched with a cell is searched, the SIM card system needs to analyze the frequency point to know whether the frequency point is applicable. When the first SIM card system is in the OOS mode, but the second SIM card system is on the network, if the operator to which the first SIM card belongs is different from the operator to which the second SIM card belongs, the first SIM card may not resolve the frequency point when searching the frequency point of the cell where the second SIM card resides, and may directly skip the frequency point, so as to save power consumption and improve efficiency.

The above describes several network communication events and the corresponding execution mode of each network communication event, and the timing when the second SIM card system executes the network communication event is described below.

After the first SIM card system acquires the network information required for executing the network communication event, the network information is stored, so that when the time for executing the network communication event by the second SIM card system is reached, the stored network information is utilized to execute the network communication event. The second SIM card system may or may not trigger the network communication event immediately after the network information is stored.

And if the triggering is immediate, immediately informing the second SIM card system to read the network information after the network information is stored in the storage unit. To achieve this, a first preset identification bit (e.g., set to 1) may be set for the network information at the time of network information storage. And when the network information of the first preset identification bit appears in the storage unit, immediately informing the second SIM card system to read the network information.

If the trigger is not immediately triggered, the network information in the storage unit can be periodically read, and when the network information of the first preset identification bit in the storage unit appears, the second SIM card system is informed to read the network information.

In order to avoid the second SIM card system repeatedly reading the same piece of network information, the network information may be invalidated after the second SIM card system reads the network information. The disabling means may be, for example, changing the flag bit from a first predetermined flag bit to a second predetermined flag bit (e.g., from 1 to 0).

In addition, in some cases, the second SIM card system does not read the network information in time due to a failure or an excessively fast moving speed of the mobile terminal, and the network communication event is not executed in time, so that the stored network information is invalid for the second SIM card system, and the network information needs to be invalidated in order to not waste resources. For example, by recording the time for storing the network information, and continuously calculating the time difference between the current time and the time for storing the network information, if the time difference does not meet the preset condition, the network information is invalidated. The means of failure can be found above. And if the time difference meets the preset condition, allowing the second SIM card system to execute the network communication event by using the stored network information.

Optionally, the format of the network information stored in the storage unit is, for example, as follows:

in summary, in the embodiment, the network communication event is executed in a manner that the first SIM card system and the second SIM card system share the network information, so that the step of acquiring the network information by the second SIM card system is omitted, and power consumption is reduced. For example, assuming that the average power consumption of a single LTE network searching card is 115mA, if the prior art is adopted, the average power consumption of the multi-card multi-standby mobile terminal network searching is 115mA × n, where n is the number of SIM cards; by adopting the embodiment, the average power consumption of the multi-card multi-standby mobile terminal for network searching is only 115 mA.
