Detailed Description

The technical solutions in the embodiments of the present application will be described clearly 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 that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

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 will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. 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.

In the related art, most of the existing electronic devices have a plurality of subscriber identity modules, and the plurality of subscriber identity modules are associated with the same radio frequency front end. Fig. 1 is a system architecture diagram of an rf front end. As shown in fig. 1, the architecture 100 of the rf front end at least includes a first rf module 110 of a first band type, a second rf module 120 of a second band type, and a transceiver 130. The electronic device can receive and transmit a plurality of radio frequency signals of the first frequency band type through the first radio frequency module 110. And the electronic device can receive and transmit the radio frequency signals of the plurality of second frequency band types through the second radio frequency module 120. The first RF module 110 and the second RF module are of different RF types.

The first rf module 110 at least includes a rf power amplifier (PA 0) 111, a Low Noise Amplifier (LNA) 112, a duplexer 113, an antenna switch 114, and an antenna 115.

The second rf module 120 at least includes an rf power amplifier (PA 1) 121, a Low Noise Amplifier (LNA) 122, a duplexer 123, an antenna switch 124, and an antenna 125.

A switch 114 and a switch 124 for switching between receiving and transmitting radio frequency signals, and switching between different frequencies. And the radio frequency power amplifier 111 and the radio frequency power amplifier 121 are used for realizing the amplification of radio frequency signals. Antenna 115 and antenna 125 for receiving and transmitting radio frequency signals. Duplexer 113 and duplexer 123 for isolating the received radio frequency signal from the transmitted radio frequency signal. A Low Noise Amplifier (LNA) 112 and a Low Noise Amplifier (LNA) 122 are used to amplify the received small signal.

For example, the first rf module 110 may be a low frequency rf module, i.e., the working band may be a low frequency band. The second rf module 120 may be a middle-high rf module 120, i.e., the working frequency band of the second rf module 120 may be a middle-high frequency band. Taking Long Term Evolution (LTE) as an example, the low frequency bands may be B5, B8, B20, B28, and the like. The middle-high frequency band may be B1, B2, B3, B4, B34, B39, B38, B40, B41, etc.

Because a plurality of user identification cards in the electronic equipment share the same radio frequency front end. Therefore, when the service state of one subscriber identity card is a transmission service, the service states of other subscriber identity cards are receiving paging services. The communication frequency band of the user identification card for transmitting the service can be the same as or different from the paging frequency band of other user identification cards.

For example, under the Non-independent Networking (NSA) architecture of the fifth generation mobile communication technology (5 g), as shown in fig. 1, the Radio frequency front end of the electronic device further includes an independent New Radio (NR) Radio frequency module 130. The operating frequency band of the rf module 130 is an NR frequency band, and the operating frequency band of the low-frequency rf module and the medium-high frequency rf module is an LTE frequency band. The NR frequency band is used for transmission of network data traffic, and the LTE frequency band is responsible for transmission of control signals. Under the NSA + LTE mode, the working frequency bands of a plurality of user identification cards have various optional combinations. When NR is N41 and the Subscriber Identity Module (SIM) card is a Subscriber Identity Module (SIM) card, table 1 shows the combination of the operating bands of the SIM1 card and the SIM2 card:

TABLE 1

As shown in table 1, the LTE band of the SIM1 card may be the same as or different from the paging band of the SIM2 card. The basic process of selecting the actual paging frequency band of the SIM2 card by the electronic equipment is as follows: the electronic equipment obtains the channel measurement result of the SIM2 card and selects the frequency band with the maximum signal intensity as the paging frequency band.

However, when the multiple frequency bands can meet the paging performance requirement of the SIM2 card, even if the multiple frequency bands include the frequency band same as the LTE frequency band of the SIM1, if the paging frequency band selected by the electronic device according to the signal strength is different from the LTE frequency band, the radio frequency front end of the electronic device is still switched from the radio frequency module corresponding to the LTE frequency band to the radio frequency module corresponding to the paging frequency band. Therefore, the electronic device selects the paging frequency band by using the signal strength, which causes the problem that the radio frequency front end is frequently switched and the power consumption of the electronic device is increased when the SIM2 performs paging.

The "subscriber identity module" related to the embodiments of the present application may be an SIM card or an access network system identity (UIM) card, or may be another type of subscriber identity module, such as a virtual SIM card.

The electronic device in the embodiment of the present application may be an electronic device having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present application are not limited specifically. Illustratively, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system. The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of observing the development principle of the framework of the application. The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system. The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present application, a developer may develop a software program for implementing the paging frequency band selection provided in the embodiment of the present application based on the system architecture of the android operating system, so that the paging frequency band selection may be operated based on the android operating system. That is, the processor or the electronic device may implement the paging frequency band selection provided in the embodiment of the present application by running the software program in the android operating system.

The following describes in detail a paging method provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The paging method of the embodiment of the application can be applied to electronic equipment at least comprising a first user identification card and a second user identification card, wherein the first user identification card and the second user identification card are associated with the same radio frequency front end. The paging method provided by the embodiment of the application is also applicable when the electronic equipment comprises a plurality of subscriber identity cards.

Fig. 2 is a flowchart illustrating a paging method according to an embodiment of the present application. As shown in fig. 2, the paging method includes:

step S210, when the first subscriber identity card successfully registers in the communication network, a network connection frequency band of the first subscriber identity card and a communication frequency band set of the second subscriber identity card are obtained.

The "communication network" related to the embodiment of the present application may be any one of: a second generation mobile communication network, a third generation mobile communication network, a fourth generation mobile communication network, and a 5G network.

Here, in case that the first subscriber identification card is successfully registered with the communication network, the first subscriber identification card may be connected with the communication network through the radio frequency front end. The first user identification card and the second user identification card are associated with the same radio frequency front end. Therefore, the first subscriber identity card is in a connected state and the second subscriber identity card is in an idle state.

And after the first user identification card successfully registers the communication network, the electronic equipment acquires the network connection frequency band of the first user identification card. The network connection frequency band is a working frequency band of the first subscriber identity module card connected communication network.

In one example, the first subscriber identification card may be SIM1 and the second subscriber identification card may be SIM2. In NSA + LTE mode, the electronic device performs a network search based on information in SIM1 and SIM2. The electronic device initiates a network registration procedure to the communication network through the SIM 1. After the network registration is completed, the electronic device acquires the LTE frequency band (i.e., the network connection frequency band) in which the SIM1 is connected to the communication network.

It should be noted that in this example, the subsequent determination mechanism is not started until SIM1 needs to be registered as NSA, and if SIM1 is not NSA, the subsequent determination mechanism is not started.

In addition, the "communication frequency band set" related to the embodiment of the present application may include a plurality of communication frequency bands, and the communication frequency band may be an operating frequency band in which the second subscriber identity card may be connected to the communication network. And when the second user identification card is in an idle state, the electronic equipment measures the physical layer according to the information in the second user identification card to acquire the channel measurement information. The channel measurement information includes measurement information of a plurality of communication bands. That is, each communication band corresponds to one measurement information. The communication band measurement information includes, but is not limited to, signal strength.

The signal strength according to the embodiment of the present application is a reference signal reception level, and may also be referred to as reference signal reception power.

Step S220, under the condition that at least two candidate paging frequency bands exist in the communication frequency band set, determining a target paging frequency band from the at least two candidate paging frequency bands according to the network connection frequency band.

Here, the candidate paging band is a communication band having a signal strength greater than a preset threshold. The preset threshold may be a threshold value of signal strength. The preset threshold may be determined according to the second subscriber identity card communication performance. Communication capabilities include, but are not limited to, call completion rate. And when the signal intensity of the communication frequency band is greater than the preset threshold value, the communication frequency band is indicated to be a working frequency band for paging connection between the second user identification card and the communication network.

When the signal strength of the communication frequency band is greater than the preset threshold, it may be indicated that, when the second subscriber identity card operates in the communication frequency band, the difference of the communication performance corresponding to the communication frequency band is within the acceptable range of the user.

In order to filter out the operating frequency that can be used in the paging phase, the electronic device compares, for each communication band in the set of communication bands, the signal strength of each communication band with a preset threshold.

In one example, the preset threshold is denoted as M, and the communication frequency Band set includes Band1, band2, band5, band8, and Band28. The electronic equipment compares the signal strength of the Band1 with the size of a preset threshold value, the signal strength of the Band2 with the size of the preset threshold value, the signal strength of the Band5 with the size of the preset threshold value, the signal strength of the Band8 with the size of the preset threshold value, and the signal strength of the Band28 with the size of the preset threshold value.

Here, the electronic device determines, according to a comparison result between each communication band in the communication band set and a preset threshold, a communication band whose signal strength is greater than the preset threshold, and uses the communication band as a candidate paging band.

In one example, the preset threshold is denoted as M, and the plurality of communication bands include Band1, band2, band5, band8, and Band28. The communication frequency bands with the signal intensity larger than M are Band1 and Band2, and the signal intensity of other communication frequency bands is smaller than M. Therefore, the candidate paging bands of the second subscriber identity card are Band1 and Band2.

The target paging frequency band related to the embodiment of the application is the optimal paging frequency band in the paging process of the second subscriber identity card. The target paging frequency band may be determined according to the number of candidate paging frequency bands and the network connection frequency band.

Specifically, when the electronic device determines that at least two candidate paging bands exist, the electronic device may determine a target paging band from the at least two candidate paging bands based on the size of the network connection band and/or the band type.

And step S230, paging is carried out by utilizing the second subscriber identity module card based on the target paging frequency band.

Here, the electronic device switches the operating frequency of the radio frequency front end to a target paging frequency band so as to perform paging by using the second subscriber identity card.

In the embodiment of the application, the communication frequency band is compared with a preset threshold value to determine a candidate paging frequency band, and a target candidate paging frequency band is determined from the candidate paging frequency band based on the network connection frequency band of the first subscriber identity card, so that the second subscriber identity card can be conveniently used for paging. Therefore, on the basis of signal strength judgment, the target paging frequency band of the second user identification card is selected by adding logic judgment of the network connection frequency band of the first user identification card, so that the switching frequency of the radio frequency front end can be reduced when the second user identification card is paged, and the purposes of reducing power consumption and prolonging service time are achieved.

In some embodiments, after step S220, the paging method further includes: and taking the communication frequency band with the maximum signal intensity as the target paging frequency band under the condition that the communication frequency band set meets a third preset condition.

Here, the third preset condition includes that the signal strength of all communication bands in the communication band set is less than the preset threshold. That is to say, the electronic device determines, according to the comparison result between each communication frequency band in the communication frequency band set and the preset threshold, that the signal strengths of all the communication frequency bands in the communication frequency bands are smaller than the preset threshold, that is, no candidate paging frequency band exists in the communication frequency band set.

When all the communication frequency bands are smaller than the preset threshold value, the signal intensity of all the communication frequency bands cannot reach the acceptable range of the user. Therefore, the communication frequency band with the maximum signal strength in the communication frequency band set is used as the target paging frequency band, so that the paging performance can be optimized as much as possible.

In some embodiments, after step S220, the paging method further includes:

and taking the candidate paging frequency band as the target paging frequency band under the condition that the communication frequency band set meets a fourth preset condition.

Here, the fourth preset condition includes that one of the candidate paging bands exists in the communication band set. That is to say, the electronic device determines that the signal strength of only one month communication band in the communication bands is greater than the preset threshold according to the comparison result between each communication band in the communication band set and the preset threshold, that is, there is one candidate paging band in the communication band set. In order to make the paging quality reach the range which can be received by the user, the electronic equipment takes the candidate paging frequency band as the target paging frequency band.

In some embodiments, to facilitate determining the size between the plurality of communication bands, and the size of the communication bands to a preset threshold. Step S220 may be specifically implemented to sequence the signal strengths of the multiple communication frequency bands with a preset threshold.

In one example, the preset threshold is denoted as M, and the plurality of communication bands include Band1, band2, band5, band8, and Band28. The electronic equipment sequences a plurality of communication frequency bands according to the signal intensity, and the obtained frequency band sequence is as follows: band1> Band2> Band5> M > Band8> Band28.

In the embodiment of the application, by sequencing the signal strengths of the plurality of communication frequency bands and the preset threshold, the magnitude relation between the plurality of communication frequency bands and the magnitude relation between each communication frequency band and the preset threshold can be quickly determined, which is beneficial to quickly determining the candidate paging frequency band and the paging frequency band in the follow-up process.

In step S220, the electronic device may determine candidate paging bands. The electronic equipment selects the optimal paging frequency band from the candidate paging frequency bands, so that the aims of reducing the switching times of the radio frequency front end and saving power consumption when the second subscriber identity card is used for paging are fulfilled. In some embodiments, step S220 may specifically be implemented as:

and taking the network connection frequency band as a target paging frequency band under the condition that the candidate paging frequency band meets a first preset condition.

Here, the first preset condition includes that at least one of the candidate paging bands is the same as the network connection band. When the network connection frequency band is the same as the paging frequency band of the second subscriber identification card, the radio frequency front end can be kept unchanged in the process that the electronic equipment performs paging through the second subscriber identification card. That is, the switch, the amplifier and the tuner on the antenna in the radio frequency front end can be kept unchanged in the original state in the paging process, the logic of a radio frequency device does not need to be switched, and the signal demodulation module of the transceiver in the radio frequency front end does not need to be changed, so that the instruction overhead of a processor and the signal demodulation module is saved, and the purpose of saving power consumption is achieved.

Thus, the electronic device may compare whether each candidate paging frequency band is the same as the network connection frequency band. When at least one candidate paging frequency band is the same as the network connection frequency band, the electronic device takes the network connection frequency band as a target paging frequency band in order to keep the radio frequency front end unchanged.

It should be noted that, because the signal strength of all candidate paging frequency bands is greater than the preset threshold, that is, the communication performance corresponding to all candidate paging frequency bands is within the acceptable range of the user. Therefore, even if the signal strength of the candidate paging frequency band identical to the network connection frequency band is not the maximum, the electronic device can still use the candidate paging frequency band as the target paging frequency band.

In the embodiment of the present application, when the network connection frequency band is a candidate paging frequency band, the network connection frequency band is used as the paging frequency band of the second subscriber identity card, so that the network connection frequency band of the first subscriber identity card is the same as the paging frequency band of the second subscriber identity card. Therefore, in the process of paging the second subscriber identity module card, the switching of the radio frequency front end is avoided, the instruction overhead of the processor and the modem is further saved, and the purposes of saving power consumption and prolonging the service life of the electronic equipment can be achieved.

When the network connection frequency band is not a candidate paging frequency band, switching among different radio frequency modules is reduced as much as possible. In some embodiments, step S220 may be specifically executed as:

under the condition that the candidate paging frequency band does not meet a first preset condition, detecting whether the frequency band type of the candidate paging frequency band meets a second preset condition, wherein the target frequency band type is the frequency band type of the network connection frequency band;

and taking the candidate paging frequency band with the maximum signal intensity of the target frequency band type as a target paging frequency band under the condition that the frequency band type of the candidate paging frequency band meets a second preset condition.

And taking the candidate paging frequency band with the maximum signal intensity as a target paging frequency band under the condition that the frequency band type of the candidate paging frequency band does not meet a second preset condition.

Here, the second preset condition includes that the frequency band type of the at least one candidate paging frequency band is the target frequency band type. The target frequency band type referred to in the embodiments of the present application is a frequency band type of a network connection frequency band. For example, the target frequency band type may be a low frequency band or a medium frequency band, and the like.

Here, after determining that the network connection frequency band is not the candidate paging frequency band, the electronic device compares the candidate paging frequency band with the frequency band type of the network connection frequency band. The electronic equipment determines that the candidate paging frequency band meets a second preset condition, namely, the candidate paging frequency band belonging to the target frequency band type exists, and the candidate paging frequency band with the maximum signal intensity is used as the target paging frequency band.

Because the switching between different frequency bands belonging to the same frequency band type only involves the switching of radio frequency devices inside the radio frequency module. Therefore, the conversion between different frequency bands of the same type can be realized by only a small amount of instructions. Therefore, in the paging process, the candidate paging frequency band with the same frequency band type as the network connection frequency band is taken as the target frequency band, so that the instruction overhead can be reduced, the power consumption is saved, and the service life of the electronic equipment is prolonged.

When the electronic device determines that the candidate paging frequency band satisfies the second preset condition, that is, the candidate paging frequency band is different from the frequency band type of the network connection frequency band, in order to optimize the paging performance, the electronic device takes the candidate paging frequency band with the maximum signal intensity as the target paging frequency band.

In order to further understand the paging method provided in the embodiment of the present application, an electronic device with dual cards, dual standby, and single pass is taken as an example for description. The electronic equipment comprises an SIM1 card (namely a first subscriber identification card) and an SIM2 card (namely a second subscriber identification card), wherein the SIM1 card and the SIM2 card share one radio frequency front end (namely the radio frequency front end). The electronic stylus can be accessed into a 5G network, wherein the 5G network architecture may be NSA + LTE. Fig. 3 is a flowchart illustrating another paging method according to an embodiment of the present application. As shown in fig. 3, the paging method includes:

in step S310, the electronic device performs network search based on SIM1 and SIM2, and SIM1 completes registration connection.

Here, the subsequent determination mechanism is started only when SIM1 has to be registered as NSA, and is not started if SIM1 is not NSA.

Step S320, reads the LTE frequency band information (i.e. network connection frequency band) of the SIM1 registration connection, and records it as frequency band a.

Here, the electronic device may acquire the registration connection information from NSA EN-DC.

In step S330, based on the SIM2, the electronic device completes signal strength measurement for different frequency bands (i.e., multiple communication frequency bands), and sorts the detected frequency bands according to the signal strength. For example: band1> Band2> Band5> Band8> Band28> Band40> Band41.

Step S340 compares the signal strength of the frequency band where the SIM2 can page (Paging) detected in step S330 with a preset signal strength threshold (i.e. a preset threshold). In the case that there is a frequency band whose signal strength is greater than the threshold value, step S360 is performed. If the signal strength of the frequency band is smaller than the threshold, step S350 is executed.

Here, a signal strength threshold is preset, denoted as M. And comparing the detected signal intensity of the Paging frequency band of the SMI2 with a preset signal intensity threshold value, and screening out frequency bands higher than the threshold value, wherein the frequency bands can be used as alternative frequency bands of the SIM2 Paging. Since the signal strength difference of the alternative frequency bands already has no influence or the influence can be tolerated on the performance of the SIM2 Paging. Here, the performance of SIM2 Paging is mainly the SMI2 call completing rate.

For example: band1> Band2> Band5> M > Band8> Band28> Band40> Band41, then Band1/2/5 is used as SIM2 Paging candidate Band.

And step S350, taking the frequency band with the maximum signal strength as the SIM2 Paging frequency band under the condition that the signal strengths of the frequency bands are all smaller than the threshold value.

Here, if the signal strength of the Paging bands of SMI2 detected in 330 is less than the predetermined signal strength threshold, the method can be applied. This result indicates that SIM2 can Paging frequency band signal quality is not high. At the moment, the performance priority of Paging is highest, and the frequency band with the maximum signal intensity is directly selected as the SIM2 Paging frequency band.

Step S360, determine whether the multiple candidate bands (i.e. candidate paging bands) include band a. If the frequency band A is included, step S370 is executed. If the frequency band A is not included, step S380 is executed.

Step S370, the electronic device directly selects the frequency band a as the SIM2 Paging frequency band (i.e. the target Paging frequency band).

Here, when the frequency band a is the SIM2 Paging frequency band, the switch, the amplifier and the Tuner (Tuner) on the antenna on the radio frequency front end may be kept unchanged, i.e. the function of SMI2 Paging may be achieved. That is to say, when SIM2 Paging is executed, the logic of the rf/antenna device (switch, LNA-low noise amplifier, tuner) does not need to be switched, i.e., the control command does not need to be issued again, and the signal demodulation module inside the transceiver does not need to be changed, so that the command overhead is saved, and the power saving effect can be achieved.

And if the frequency band A is not included, continuously judging the frequency information of the frequency band A.

In step S380, it is determined whether the band type of the a band (i.e., the target band type) is the same as the band type of the candidate information. If so, step S390 is performed. If not, step S3010 is executed.

And step S390, screening the alternative frequency band with the frequency band type being the target frequency band type, and taking the alternative frequency band with the maximum signal intensity as the frequency band of the SIM2 Paging.

For example, the a Band is a Low Frequency Band (LB), and a plurality of candidate bands include other LBs, and the LB Band is preferably selected from the SIM2 Paging Band. The electronic device judges according to the signal strength of the candidate frequency band belonging to the LB, for example: a is LB, and the alternative frequency bands are: band1> Band28> Band5> M > Band8> Band40, wherein Band1/40 is a Medium High Frequency Band (MHB), band5/8/28 is LB, and therefore, the SMI2 Paging Band is selected to be Band28.

If the A frequency band is MHB and the plurality of alternative frequency bands comprise other MHBs, the frequency band of the SIM2 Paging preferentially selects the MHB frequency band. The electronic equipment judges according to the signal intensity of the alternative frequency band belonging to the MHB.

Here, the SIM2 Paging frequency band selects a frequency band with a frequency close to the frequency band a connected to the SIM1, and when the SIM2 Paging is performed, the same device logic is changed at the front end of the radio frequency.

And step 390, taking the alternative frequency band with the maximum signal intensity as the frequency band of the SIM2 Paging under the condition that the frequency band type of the frequency band A is different from the frequency band type of the candidate information.

Therefore, according to the priority, the instruction overhead of the processor and the modulation and demodulation module added by circuit switching in the SIM2 Paging process can be reduced, the power saving effect is achieved, the service time of the terminal is prolonged, and the user experience is improved.
