Description

Dual-card communication method and terminal equipment

Technical Field

The present application relates to the field of communications, and more particularly, to a method and a terminal device for dual card communication in the field of communications.

Background

With the development of communications, most of the current terminal devices (e.g., mobile phones) support a dual card dual standby (dual sim dual standby, DSDS) or dual card dual pass (dual sin dual active, DSDA) mode. In DSDA mode, the terminal device supports service concurrency of dual cards, that is, dual cards can send or receive simultaneously, when one card executes call service, the other card can receive incoming call, and also can execute data service (i.e. surfing the internet). In the DSDS mode, the terminal device does not support concurrency of dual-card services, when one card executes call services, the other card cannot perform data services, and when one card executes data services, the other card can receive incoming calls, but the incoming calls interrupt the data services, for the main card, the call services of the auxiliary card enable the main card to be incapable of performing data services, and the auxiliary card can occupy the antenna due to actions such as network searching, measurement, tracking area updating (tracking area update, TAU), short messages, multimedia messages, periodic registration and the like, so that the internet surfing experience of the main card is affected.

It can be seen that the user experience of the DSDA mode is higher compared to the DSDS mode. However, the current support of DSDA mode by the mainstream chips in the terminal device in the market is imperfect, and in many scenarios, the terminal device is in DSDS mode instead of DSDA mode, thereby reducing the user experience.

Detailed Description

The technical scheme of the application will be described below with reference to the accompanying drawings.

The technical scheme of the embodiment of the application is suitable for the terminal equipment which can communicate with the network equipment and supports double-card communication, each card can support telephone service and data service (namely, internet service), for example, the terminal equipment can be a mobile phone, a smart watch, a smart bracelet or a tablet personal computer, and the like, and the embodiment of the application does not limit the specific type of the terminal equipment.

The technical scheme of the embodiment of the application can be applied to various communication systems, such as: global system for mobile communications (global system for mobile communications, GSM), general packet radio service (general packet radio service, GPRS), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), time division code division multiple access (time-division code division multiple access, TD-SCDMA), long term evolution (long term evolution, LTE), LTE frequency division duplex (frequency division duplex, FDD), LTE time division duplex (time division duplex, TDD), fifth generation new wireless (5th generation new radio,5G NR) or future sixth generation (6th generation,6G) systems, etc., wherein 5G NR is abbreviated as NR.

The embodiment of the application is applicable to a mobile communication system comprising a plurality of base stations and at least one terminal device, wherein the plurality of base stations at least comprise a base station capable of supporting a 5G network and a base station capable of supporting a 4G network. Illustratively, as shown in fig. 1, the mobile communication system includes a base station 110, a base station 120, and a terminal device 130, one of the base station 110 and the base station 120 being capable of supporting a 4G network, the other being capable of supporting a 5G network, the terminal device 130 being connectable to at least one of the base station 110 and the base station 120. For convenience of description, a base station supporting a 4G network will be abbreviated as a 4G base station, and a base station supporting a 5G network will be abbreviated as a 5G base station.

If the terminal device 130 is connected to one of the base station 110 and the base station 120, both the dual cards reside in the same network (4G network or 5G network). If the terminal device 130 is connected to both the base station 110 and the base station 120, then the following 3 cases are possible. Case 1, terminal device supports dual connection of 4G network and 5G network, and each of two cards is in dual connection state, i.e., each card connects 4G network and 5G network simultaneously. Case 2, one card resides in a 4G network and the other card resides in a 5G network. Case 3, the terminal device supports dual connection of LTE network and 5G network, where one card resides in 4G network or 5G network, and the other card connects both 4G network and 5G network.

It should be noted that, since the dual card does not necessarily support the same operator, when the dual card is simultaneously camped on the 4G network or the 5G network, the 4G base station or the 5G base station on which the dual card is camped may not be the same, and thus, the mobile communication system may include a plurality of base stations 110 and/or a plurality of base stations 120. When a base station (e.g., base station 110 or base station 120) is a base station of a shared network, the system allows the dual card to reside in the network supported by the base station even if the dual card does not support the same operator, where the shared network is a network shared by different operators.

Assume that a dual card supports different operators, a card 1 supports operator 1, a card 2 supports operator 2, and a mobile communication system includes one base station 110 and two base stations 120.

In an example, if base station 110 is a 4G base station of a shared 4G network and base station 120 is a 5G base station of a non-shared 5G network, one base station 120 supports operator 1 and another base station 120 supports operator 2. If the dual cards reside on the 4G network at the same time, then both cards reside on the same base station 110 (i.e., 4G base station); if the dual card resides on the 5G network at the same time, then the dual card resides on a different base station 120 (i.e., a 5G base station), card 1 resides on the base station 120 corresponding to carrier 1, and card 2 resides on the base station 120 corresponding to carrier 2.

In another example, if base station 110 is a 5G base station of a shared 5G network and base station 120 is a 4G base station of a non-shared 4G network, one base station 120 supports operator 1 and the other base station 120 supports operator 2. If the dual cards reside on the 5G network at the same time, then both cards reside on the same base station 110 (i.e., 5G base station); if the dual card resides on the 4G network at the same time, then the dual card resides on a different base station 120 (i.e., a 4G base station), card 1 resides on the base station 120 corresponding to carrier 1, and card 2 resides on the base station 120 corresponding to carrier 2.

Assume again that the dual card supports different operators, the card 1 supports operator 1, the card 2 supports operator 2, the mobile communication system includes two base stations 110 and two base stations 120, the base stations 110 are 4G base stations of the unshared 4G network, one base station 110 supports operator 1, the other base station 110 supports operator 2, the base stations 120 are 5G base stations of the unshared 5G network, one base station 120 supports operator 1, and the other base station 120 supports operator 2. If the dual card resides on the 4G network at the same time, the dual card resides on a different base station 110 (i.e., a 4G base station), the card 1 resides on the base station 110 corresponding to the operator 1, and the card 2 resides on the base station 110 corresponding to the operator 2; if the dual card resides on the 5G network at the same time, then the dual card resides on a different base station 120 (i.e., a 5G base station), card 1 resides on the base station 120 corresponding to carrier 1, and card 2 resides on the base station 120 corresponding to carrier 2.

It should be understood that the mobile communication system shown in fig. 1 is only schematically illustrated and should not be construed as limiting the embodiments of the present application.

The communication system and the terminal device according to the embodiments of the present application are described above, and related terms related to the embodiments of the present application are described below.

Double card double standby (dual sim dual standby DSDS)

The dual-card mode supported by the terminal equipment can also be understood as the dual-card capability of the terminal equipment, and the receiving antennas of the dual cards are multiplexed in a time-sharing manner. In the DSDS mode, the terminal equipment does not support the concurrency of the double-card service, and the method is specifically expressed as follows: (1) When one card performs a call service, the other card cannot perform a data service (i.e., surf the internet); (2) While one card is executing the data service, the other card may receive the incoming call, but the incoming call interrupts the data service.

For the main card in the dual-card, the call service of the auxiliary card can make the main card unable to perform data service, and the auxiliary card can preempt the antenna due to network searching, measurement, tracking area updating (tracking area update, TAU), short message, multimedia message, periodic registration and other actions, so that the network access experience of the main card is poor.

Dual receiver Dual standby (DR-DSDS)

The other dual-card mode supported by the terminal device can be understood as another dual-card capability of the terminal device, and the receiving antennas of the dual cards can be used for diversity multiplexing, namely, one main set for the card and the other diversity for the card, and the dual cards can be received at the same time but cannot be transmitted at the same time. In DR-DSDS mode, (1) when one card performs a call service, the other card has a signal, but cannot respond to paging, and cannot perform TAU; (2) When one card performs a data service, the other card needs to preempt a Radio Frequency (RF) antenna when performing uplink transmission, thereby affecting the experience of the card performing the data service.

Double card double pass (dual sin dual active DSDA)

Another dual card mode supported by the terminal device may also be understood as another dual card capability of the terminal device. In DSDA mode, the terminal device supports service concurrency of two cards, that is, two cards can send or receive simultaneously, when one card executes call service, the other card can receive incoming call, and also can execute data service (i.e. surfing the internet).

The DSDA mode may further include two modes, a DSDA transmit shared mode and a DSDA transmit exclusive mode. In the DSDA transmission sharing mode, two cards share an antenna and transmit in a time-sharing manner during uplink transmission, and two cards respectively use different antennas during downlink transmission, however, the performance experience of surfing the internet of a user is lost due to the uplink transmission sharing antenna of the two cards. In the DSDA transmitting exclusive mode, two cards respectively use different antennas in uplink transmission and respectively use different antennas in downlink transmission, the uplink transmission and the downlink transmission are completely independent, the performance experience of the user on the internet is basically free of loss, and the performance experience is better than that in the DSDA transmitting exclusive mode.

Non-independent Networking (NSA) and independent networking (SA)

With the development of 5G, 5G includes two networking modes, NSA and SA.

NSA refers to deployment of a 5G network by using existing facilities such as a 4G core network, and is a networking mode in which 4G and 5G are integrated. The 5G carrier based on NSA architecture only carries user data, and control signaling is still transmitted through the 4G network. In NSA, 5G cannot work alone, but only as a complement to 4G, sharing the flow of 4G.

The SA refers to a newly created 5G network, including a new base station, a backhaul link, and a core network. The SA introduces new network elements and interfaces, adopts new technologies such as network virtualization, software defined network and the like on a large scale, combines with 5G NR, and simultaneously exceeds 3G and 4G systems in terms of technological challenges faced by protocol development, network planning deployment and interworking interoperability. At present, the SA has two networking modes, one networking mode is to connect a 5G core network by adopting a 5G base station, which is the final form of a 5G network architecture and can support all applications of 5G, but the cost is quite high; another networking mode is to upgrade the existing 4G base station into an enhanced 4G base station, and access the enhanced 4G base station to the 5G core network, which is less expensive.

In the embodiment of the application, 4G can be used as an alternative description of LTE, 5G can be used as an alternative description of NR, and if not specifically stated, the two can be used as alternative descriptions.

As previously described, the user experience of the DSDA mode is better than that of the DSDS mode. However, the current support of DSDA mode by the mainstream chips in the terminal device on the market is imperfect, and in many scenarios, the terminal device is in DSDS mode instead of DSDA mode, thereby reducing the user experience. It can be seen that by having the terminal device in DSDA mode as much as possible, the user experience can be improved.

The dual-card mode supported by the terminal device is related to the network and the frequency band where each card is located, at present, a partial frequency band of the NR SA network and a partial frequency band of the LTE network support the DSDA mode, and the partial frequency band of the NR SA network can support the DSDA mode, wherein NR SA represents a 5G network, particularly a 5G network with SA as a networking mode, abbreviated as NR SA, and LTE represents a 4G network.

The DSDA mode includes one or more DSDA combinations including a dual card network type and frequency band. For convenience of description, DSDA combinations may be expressed in terms of "network 1 band number+network 2 band number". In addition, the frequency band of the LTE network may be abbreviated as an LTE frequency band, the frequency band of the NR network may be abbreviated as an NR frequency band, the LTE frequency band may be represented by an LTE frequency band number, the LTE frequency band number may be represented by Bx, x is an integer greater than 0, for example, B1, and similarly, the NR frequency band may be represented by an NR frequency band number, the NR frequency band number may be represented by nx, and n is an integer greater than 0, for example, n78.

Illustratively, one DSDA combination of DSDA modes is nrsn41+lte b1, which means that one card resides in the frequency band indicated by n41 in the NR SA network, n41 is an NR frequency band number, which means one NR frequency band, and the other card resides in the frequency band indicated by B1 in the LTE network, B1 means an LTE frequency band number, which means one LTE frequency band.

From the above, it can be seen that as long as the network type and frequency band of the network where the two cards currently reside satisfy the network type and frequency band in any one DSDA combination of the DSDA modes, the DSDA mode can be formed between the two cards, and the terminal device can be in the DSDA mode. Based on this, the embodiment of the present application proposes that, by using network information of the current location of the terminal device and a DSDA combination supported by the terminal device and capable of forming a DSDA mode, whether the terminal device has a DSDA combination at the current location is determined in advance, if the DSDA combination exists, a calibration operation is performed on at least one card, so that the dual card finally resides in a network type and a frequency band of the dual card represented by the DSDA combination determined in advance, so as to form the DSDA mode, so as to improve user experience.

It should be noted that, in view of the fact that the current NR network in which the terminal device supports the DSDA mode is mostly an NR SA network, the NR network in the DSDA mode described in the foregoing is also an NR SA network, but the NR network in the embodiment of the present application is not limited to the NR SA network, and an NR NSA network that may support the DSDA mode is also included in the future, where the NR NSA network represents an NR network with a networking manner of NSA. For convenience of description, an NR SA network is described below as one example of an NR network, but is not limited to an NR SA network.

It should be further noted that, although the network types supporting DSDA modes currently include LTE networks and NR networks, other network types (e.g., 6G networks) that may be included in the future are within the scope of the embodiments of the present application, as long as DSDA modes can be formed between two cards. For convenience of description, the description of network types supporting DSDA mode will be given below by taking an LTE network or an NR network as an example, and the embodiment of the present application should not be limited.

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

Fig. 3 is a schematic flow chart of a method 300 of dual card communication provided by an embodiment of the present application. The method 300 may be performed by a terminal device supporting dual card communication, or may be performed by a chip in the terminal device, and embodiments of the present application are not limited in any way. For convenience of description, the method 300 will be described in detail by taking a terminal device as an example.

In S311, the terminal device acquires network information of a first location where the terminal device is currently located. The network information is used for indicating the network type and the frequency band supported by the first position.

Illustratively, the network information includes type information for indicating a network type supported by the first location and frequency band information for indicating a frequency band supported by the first location.

The number of network types supported by the first location may be one or more, the network types may be one or more of all network types supported in the market today, e.g. the network types supported by the first location may comprise at least one of a GSM network, a WCDMA network, a CDMA network, a GPRS network, an LTE network, an NR network.

The number of frequency bands supported by the first location may be one or more, and the one or more frequency bands may be frequency bands in the same type of network or frequency bands in different types of networks, which is not limited in any way.

The manner in which the terminal device acquires the network information of the current location of the terminal device can be shown in the following manner 1 and manner 2. It should be understood that the following modes 1 and 2 are only illustrative, and any mode capable of acquiring network information of the current location of the terminal device is within the scope of the embodiments of the present application, and should not be limited thereto.

Mode 1

And the terminal equipment obtains the network information of the first position from the cloud.

In this mode 1, the cloud end stores network information of a plurality of locations including network information of a first location.

In an example, the terminal device may report the first location where the terminal device is currently located to the cloud terminal, and the cloud terminal issues network information of the first location to the terminal device based on the first location.

In another example, the terminal device may also periodically obtain network information of a city or a partial area where the user is located from the cloud, store the network information locally, and obtain, when in use, network information of the first location from the network information.

For example, the cloud may generate network information at different locations by way of network crowdsourcing.

Network crowdsourcing is a new business model, which is to convert knowledge, wisdom, experience, skills and the like of people into an internet model with actual benefits through a network, and a plurality of users participate in projects, so that the users are not only servers but also experienters. In the embodiment of the application, for example, the network can mobilize a large number of users, each user records the network data of the positions which the user has gone through the terminal equipment of the user and uploads the network data to the cloud, so that the cloud can acquire the network data of a plurality of positions, and the cloud can acquire the network information of different positions by processing the network data.

As shown in fig. 4, the combination of network information of a plurality of locations can be regarded as one communication map including a plurality of grids each representing one location, and each of the grids has recorded therein the network types and frequency bands supported by the corresponding location. For example, the grid indicated in fig. 4 represents the first location where the terminal device is currently located.

It should be appreciated that the size of the grid represents the area size of the corresponding location. It will also be appreciated that the smaller the area of the location represented by the network, the better the accuracy of the grid, and conversely, the larger the area of the location represented by the grid, the worse the accuracy of the grid.

Mode 2

The terminal equipment obtains the network information of the first position through the local information.

In this embodiment 2, the local information includes network information of a plurality of locations, and the difference from embodiment 1 is that the local information is related to only data of a specific user, and therefore, the local information includes not much network information of a location where a specific user has previously moved, for example, a home, a company, a teaching building, a mall, a cafe, a hospital, or the like.

In some embodiments, when the terminal device detects that the location where the terminal device is located changes, network information of a new location after the change of the terminal device is acquired. Therefore, in S311, when the terminal device detects that the location where the terminal device is located changes, network information of the first location where the terminal device is currently located is acquired.

In S312, the terminal device determines whether a DSDA mode is formed between the two cards at the first location.

If the terminal equipment determines that the DSDA mode is formed between the double cards at the first position, ending the flow; if the terminal device determines that the DSDA mode is not formed between the two cards at the first location, step S313 is continued to be performed to form the DSDA mode between the two cards as much as possible so that the terminal device is in the DSDA mode if a certain condition is satisfied.

In the embodiment of the application, the DSDA mode of the terminal equipment is determined by the concurrency capability of the RF front end, so that the dual-card mode of the terminal equipment can be identified through the RF drive.

In some embodiments, when the terminal device detects a change in the location of the terminal device (e.g., the location of the terminal device changes to the first location), the terminal device determines whether the DSDA mode is formed between the dual cards.

That is, before executing S312, the terminal device may first detect whether the location of the terminal device changes, and if it is detected that the location of the terminal device changes, S312 is executed.

It will be appreciated that in this embodiment the terminal device will not only detect that the location where it is located has changed, but will also detect that it is currently in the first position where it determines whether DSDA mode is formed between the two cards.

Of course, in other embodiments, the terminal device may also periodically determine whether the DSDA mode is formed between the dual cards, which is not limited in the embodiments of the present application.

In S313, the terminal device determines whether there is a DSDA combination supported by the terminal device capable of forming a DSDA mode at the first location according to the network information of the first location.

Specifically, the terminal device traverses the network type and the frequency band indicated by the network information of the first location based on the DSDA combination supported by the terminal device and capable of forming the DSDA mode, and determines whether the DSDA combination supported by the terminal device exists at the first location.

If the terminal device determines that there is no DSDA combination supported by the terminal device at the first position, ending the flow.

If the terminal device determines that there is a DSDA combination supported by the terminal device at the first location, meaning that the dual card has an opportunity to form a DSDA mode such that the terminal device is in the DSDA mode, step S314 is continued to be performed.

In this step, when it is determined that there are DSDA combinations supported by the terminal device at the first location, the number and the specific content of the DSDA combinations supported by the terminal device at the first location can also be determined, i.e., at least one DSDA combination supported by the terminal device at the first location can be determined, wherein the at least one DSDA combination includes one or more DSDA combinations.

For example, the network types indicated in the network information of the first location include an NR-SA network and an LTE network, the frequency bands include frequency bands indicated by n41, n1, n78, B1, B3, and B41, 3 DSDA combinations in the network information of the first location, and DSDA combination 1: NR SA n1+NR SA n1, DSDA combination 2: NR SA n1+ NR SA n78, DSDA combination 3: nrsan41+lte b1. If the DSDA combination supported by the terminal device is nrsn41+lte b1, which is the same as DSDA combination 3 in the network information, there is one DSDA combination supported by the terminal device at the first location. If the DSDA combination supported by the terminal device is nrsn41+lte b3, which is different from any DSDA combination in the network information, there is no DSDA combination supported by the terminal device at the first location.

It should be understood that the DSDA combinations supported by the same terminal device are fixed, and the DSDA combinations supported by different terminal devices may be the same or different, and may be specifically determined according to the model number or hardware information of the terminal device. For convenience of description, combinations of the two-card modes supported by a certain terminal device are listed in the form of table 1, in table 1, there are 3 DSDA combinations of the DSDA modes, a DSDA combination formed by nrsn1+nrsn1 in the DSDA transmission sharing mode, a DSDA combination formed by nrsn1+nrsn78 in the DSDA transmission exclusive mode, and a DSDA combination formed by nrsn1+lte B41 in the DSDA transmission exclusive mode. In an implementation, dual card mode information may be preconfigured in the terminal device, where the dual card mode information is used to indicate various combinations of dual card modes supported by the terminal device, including all DSDA combinations of DSDA modes supported by the terminal device, each combination including a network type and a frequency band of a dual card, and all combinations of dual card modes shown in table 1 may be indicated by the dual card mode information.

It should also be understood that the DSDA combinations supported by the same terminal device at different locations may be the same or different, depending primarily on the type of network and frequency band supported by the respective locations.

TABLE 1

In S314, the terminal device performs a calibration operation on at least one card of the dual cards so that a DSDA mode is formed between the dual cards. Wherein the at least one card comprises one card or two cards.

Specifically, the terminal device performs a calibration operation on at least one card of the dual cards according to a target DSDA combination of the at least one DSDA combination supported by the terminal device at the first location, so that the network type and the frequency band of the dual card of the terminal device are the same as those of the dual card of the target DSDA combination.

If at least one DSDA combination is one DSDA combination, then the target DSDA combination is this unique DSDA combination. If at least one DSDA combination is a plurality of DSDA combinations, the target DSDA combination is a certain DSDA combination of the plurality of DSDA combinations, and the target DSDA combination may be any one of the plurality of DSDA combinations or may be a DSDA combination determined according to a rule, and is not limited in any way.

The purpose of the calibration operation is to cause DSDA modes to form between the dual cards, for either of the dual cards, in some embodiments the calibration operation for either card includes at least one of the following:

A first operation for causing either card to reside in the LTE network;

a second operation for causing either card to reside on the NR network;

and a third operation of recording the frequency band where any card currently resides in the blacklist of the first position, so that the terminal equipment reselects the frequency band for any card to reside. Wherein the frequency band in the blacklist of the first location is a different frequency band than the frequency band of any card represented by the target DSDA combination.

The above-described calibration operation is a calibration operation for either one of the two cards, and for convenience of description, one of the two cards is referred to as a first card, and the other is referred to as a second card. One of the first card and the second card is a main card, and the other is a sub card.

For the first card, at least one operation included in the calibration operation of the first card may be replaced with the following description:

a first operation for causing the first card to reside in the LTE network;

a second operation for causing the first card to reside on the NR network;

and a third operation of recording the frequency band where the first card currently resides in the blacklist of the first position, so that the terminal equipment reselects the frequency band for the first card to reside.

For the second card, at least one operation included in the calibration operation of the second card may be replaced with the following description:

A first operation for causing the second card to reside in the LTE network;

a second operation for causing the second card to reside on the NR network;

and a third operation of recording the frequency band where the second card currently resides in the blacklist of the first position, so that the terminal equipment reselects the frequency band for the second card to reside.

In embodiments in which the calibration operation of any one card comprises a first operation, in some embodiments the first operation comprises an operation to shut down the NR network of any one card, or the first operation comprises an operation to reduce the priority of the NR network of any one card.

It should be understood that in an embodiment in which the first operation includes an operation of lowering the priority of the NR network of any one card, lowering the priority of the NR network can suppress the terminal device from causing any one card to enter the NR network by reselection or by initial network selection, but cannot suppress the network from causing any one card to enter the NR network by B1 event measurement. Wherein, the B1 event measurement refers to measuring adjacent NR cells satisfying the B1 event, the adjacent NR cells are adjacent to the LTE cell where the any card currently resides, and the B1 event refers to measuring an event that the quality of the adjacent NR cells is higher than a preset threshold.

Thus, to avoid that any one card enters the NR network through the B1 event measurement, the first operation optionally further comprises an operation of suppressing the any one card for the B1 event measurement. If the terminal device detects an adjacent NR cell satisfying the B1 event, any one of the cards may be connected to the NR cell, and at this time, any one of the cards may be in an evolved universal mobile telecommunications system (universal mobile telecommunications system, UMTS) terrestrial radio access network (evolved UMTS terrestrial radio access network, E-UTRAN) new radio-dual connectivity (EUTRA-NR dual connectivity, ENDC) state or switched from the LTE network to the NR network, and cannot form a DSDA mode with another card, so it is necessary to suppress measurement of the B1 event by the terminal device.

Illustratively, the method of suppressing the B1 event measurement by any one card may be as follows.

In an example, the terminal device does not measure the neighboring NR cells for any card, nor does it naturally report a B1 event report to the base station indicating the B1 event measurement result.

In another example, the terminal device measures the neighbor NR cells for any card, but does not report the B1 event report to the base station.

In embodiments where the calibration operation of any one card comprises a second operation, in some embodiments the second operation comprises an operation to open the NR network of any one card.

In the embodiment in which the calibration operation includes the third operation, if the plurality of frequency bands exist at the first location and are different from the frequency band of a card in the target DSDA combination, or in other words, the plurality of frequency bands at the first location do not conform to the frequency band of a card in the target DSDA combination, the plurality of frequency bands include the frequency band in which any card currently resides, and since the terminal device has already determined the target DSDA combination for performing the calibration operation, the terminal device also knows that the plurality of frequency bands are different from the frequency band of a card in the target DSDA combination, before the frequency band is reselected, the terminal device not only adds the frequency band in which any card currently resides to the blacklist at the first location, but also adds the frequency band in which any card currently resides to the blacklist at the first location, so that the terminal device can accurately camp on the frequency band of a card in the target DSDA combination when reselecting the frequency band.

Further, in the embodiment in which the calibration operation includes the third operation, the frequency band may be recorded by a frequency band number, that is, recorded in the blacklist is a frequency band number for indicating the frequency band, for example.

It should be understood that the terminal device may perform one or more of the calibration operations on one or both of the two cards when performing the calibration operation; in addition, when the calibration operation is performed on both cards, the calibration operation performed by each card may be the same or different, and the embodiment of the present application is not limited at all, so long as the DSDA mode can be formed between the two cards.

It should also be understood that the terminal device performs which of the calibration operations on which of the dual cards, depending on the state in which the dual card is currently in and the DSDA combination supported by the terminal device at the first location, embodiments of the present application are not limited in any way.

In some embodiments, if the frequency band where either card of the dual cards resides does not satisfy the frequency band of a card in the target DSDA combination supported by the terminal device at the first location, then a third operation may be performed on either card.

It is assumed that, according to the network information of the first location and the DSDA combination supported by the terminal device and capable of forming the DSDA mode, it is determined that there is one DSDA combination supported by the terminal device at the first location, that is, a target DSDA combination, specifically, a DSDA combination of nrsn1+nrsn1. In addition, for convenience of description, contents before "+" denote a network type and a frequency band of the first card, and contents after "+" denote a network type and a frequency band of the second card, and the following explanation is provided herein.

For example, if the dual card of the terminal device does not temporarily form the DSDA mode, and the current combination of the dual card is nrsa1+nrsn2, the network type and the frequency band of the network where the first card currently resides both satisfy the network type and the frequency band of one card in the target DSDA combination, and the network type of the network where the second card currently resides satisfies the network type of the other card in the target DSDA combination but the frequency band does not satisfy the network type of the other card, the terminal device may perform a third operation on the second card, and record the frequency band where the second card currently resides (the frequency band indicated by n 2) in the blacklist at the first location, so that the second card reselects the frequency band to reside in the frequency band indicated by n1 in the NR SA network. It should be understood that, in the process that the terminal device reselects the frequency band for the second card to reside, if the frequency band indicated by n1 and other multiple frequency bands exist in the NR SA network at the first location, the other multiple frequency bands include the frequency band indicated by n2 where the second card currently resides, and before the terminal device reselects the frequency band, the terminal device not only adds the frequency band indicated by n2 where the second card currently resides to the blacklist at the first location, but also adds the frequency band other than the frequency band indicated by n2 in the other multiple frequency bands to the blacklist at the first location, so that the terminal device can accurately reside in the frequency band indicated by n1 when reselecting the frequency band.

In other embodiments, if the network type and the frequency band of the network where either card of the dual cards resides do not satisfy the network type and the frequency band of a card of the target DSDA combination supported by the terminal device at the first location, the first operation or the second operation may be performed on either card, and if after the first operation or the second operation is performed, the frequency band where either card resides does not satisfy the frequency band of a card of the target DSDA combination, the third operation may be performed on either card.

It is assumed that, according to the network information of the first location and the DSDA combination of the DSDA mode supported by the terminal device, it is determined that there is one DSDA combination supported by the terminal device at the first location, that is, the target DSDA combination, specifically, the DSDA combination of nrsn1+nrsan1. For example, if the dual card of the terminal device does not temporarily form the DSDA mode, and the current combination of the dual card is nrsn1+lte b1, the network type and the frequency band of the network where the first card currently resides both satisfy the network type and the frequency band of one card in the target DSDA combination, and the network type and the frequency band of the network where the second card currently resides do not satisfy the network type and the frequency band of the other card in the target DSDA combination, then the terminal device may perform a second operation on the second card, so that the second card resides in the NR SA network. If the second card resides in the frequency band indicated by n1 in the NR SA network, a DSDA mode is formed between the two cards. If the second card does not reside in the frequency band indicated by n1 in the NR SA network, the terminal device may continue to perform a third operation on the second card, and record the frequency band where the second card currently resides in the NR SA network in the blacklist at the first location, so that the terminal device reselects the frequency band for the second card to reside in the frequency band indicated by n1 in the NR SA network, so as to finally reside in the frequency band indicated by n1 in the NR SA network.

It is further assumed that, according to the network information of the first location and the DSDA combination supported by the terminal device and capable of forming the DSDA mode, it is determined that there is one DSDA combination supported by the terminal device at the first location, that is, the target DSDA combination, specifically, the DSDA mode combined as nrsan1+lte b1. For example, if the dual card of the terminal device does not temporarily form the DSDA mode, and the current combination of the dual card is nrsa1+nrsan2, the network type and the frequency band of the network where the first card currently resides both satisfy the network type and the frequency band of one card in the target DSDA combination, and the network type and the frequency band of the network where the second card currently resides do not satisfy the network type and the frequency band of the other card in the target DSDA combination, then the terminal device may perform the first operation on the second card, so that the second card resides in the LTE network. If the second card resides in the frequency band indicated by B1 in the LTE network, a DSDA mode is formed between the two cards. If the second card does not reside in the frequency band indicated by B1 in the LTE network, the terminal device may continue to perform a third operation on the second card, and record the frequency band where the second card currently resides in the LTE network in the blacklist at the first location, so that the terminal device reselects the frequency band for the second card to reside, so as to finally reside in the frequency band indicated by B1 in the LTE network.

In other embodiments, if the network type and the frequency band of the network where the dual card resides do not satisfy the network type and the frequency band of the dual card in the target DSDA combination, the first operation or the second operation may be performed on each card, and if the frequency band where at least one card resides after performing the first operation or the second operation does not satisfy the frequency band of at least one card in the target DSDA combination, the third operation may be performed on at least one card.

It is assumed that, according to the network information of the first location and the DSDA combination supported by the terminal device and capable of forming the DSDA mode, it is determined that there is one DSDA combination supported by the terminal device at the first location, that is, a target DSDA combination, specifically, a DSDA combination of nrsn1+nrsn1. For example, the dual card of the terminal device does not temporarily form the DSDA mode, if the current combination of the dual card is LTE b1+lte b3, neither the network type nor the frequency band of the network where the dual card currently resides satisfies the network type and the frequency band of the dual card in the target DSDA combination, and if the NR network of the dual card is closed or the NR network has a priority lower than that of the LTE network, the terminal device may perform a second operation on the dual card, so that the dual card resides in the NR SA network. For the first card, if the first card resides in the frequency band indicated by n1 in the NR SA network, a DSDA mode can be formed between the two cards; if the first card does not reside in the frequency band indicated by n1 in the NR SA network, the terminal device may continue to perform a third operation on the first card, that is, record the frequency band where the first card currently resides in the NR SA network in the blacklist at the first location, so that the terminal device reselects the frequency band for the first card to reside in the frequency band indicated by n1 in the NR SA network. For the second card, if the second card resides in the frequency band indicated by n1 in the NR SA network, a DSDA mode can be formed between the two cards; if the second card does not reside in the frequency band indicated by n1 in the NR SA network, the terminal device may continue to perform a third operation on the second card, and record the frequency band where the second card currently resides in the NR SA network in the blacklist at the first location, so that the terminal device reselects the frequency band for the second card to reside in the frequency band indicated by n1 in the NR SA network, so as to finally reside in the frequency band indicated by n1 in the NR SA network.

In step S313, if the terminal device determines that the DSDA combination supported by the terminal device at the first location includes a plurality of DSDA combinations, in some embodiments, the terminal device determines a DSDA combination having a highest priority among the plurality of DSDA combinations as a target DSDA combination, and performs a calibration operation on at least one card of the dual cards such that a state of the dual card after performing the calibration operation is the same as a state of the dual card indicated by the target DSDA combination.

In some embodiments, the priority of DSDA combinations may be defined from the capabilities of the dual card mode.

The better the capability of the dual card mode, the higher the priority of the DSDA combination, whereas the worse the capability of the dual card mode, the lower the priority of the DSDA combination. The capability of the dual card mode is from high to low: DSDA transmission exclusive sharing > DSDA transmission sharing > DR-DSDS > DSDS, then the priority of the DSDA combination from high to low may be: DSDA transmission exclusive share > DSDA transmission shared > DR-DSDS > DSDS.

In other embodiments, the priority of DSDA combinations may be defined from the magnitude of the calibration amplitude of the card by the terminal device.

The smaller the calibration amplitude of the terminal device to the card, the higher the priority of the DSDA combination, whereas the larger the calibration amplitude of the terminal device to the card, the lower the priority of the DSDA combination. Illustratively, the calibration amplitude for the card is in order of from small to large: the third operation > the first operation or the second operation is performed on the card.

In other embodiments, the priority of DSDA combinations may be defined from the level of convenience in calibrating the card from the terminal device.

The higher the convenience of the terminal device for calibrating the card, the higher the priority of the DSDA combination, and conversely, the lower the convenience of the terminal device for calibrating the card, the lower the priority of the DSDA combination. Illustratively, the order of the convenience of the terminal device to calibrate the card from high to low is: performing a calibration operation on one card > performing a calibration operation on both cards.

In other embodiments, the priority of DSDA combinations may be defined based on other factors, and embodiments of the present application are not limited in any way.

It should be noted that the priorities of the DSDA combinations may be used alone or in combination.

In combining the priorities of the DSDA combinations described above, in some embodiments, the capability of the dual card mode is combined with the magnitude of the calibration of the card by the terminal device, the priorities of the DSDA combinations are preferentially considered from the capability of the dual card mode, and the priorities of the DSDA combinations are considered from the magnitude of the calibration of the card by the terminal device. For example, if there are 3 DSDA combinations supported by the terminal device at the first location, the DSDA transmits 2 DSDA combinations of the exclusive mode, and the DSDA transmits 1 DSDA combination of the shared mode. Before performing the calibration operation, the capability of the dual card mode is preferentially considered, 2 DSDA combinations of the DSDA emission exclusive mode are taken as candidate combinations, and in combination with consideration of the magnitude of the calibration amplitude of the card by the terminal device, it is found that performing the third operation on the sub-card in the dual card can make the state of the dual card after calibration identical to the DSDA combination 1 of the DSDA emission exclusive mode, and performing the second operation on the sub-card in the dual card can make the state of the dual card after calibration identical to the DSDA combination 2 of the DSDA emission exclusive mode, so that the DSDA combination 1 of the DSDA emission exclusive mode is taken as a target DSDA combination, and performing the third operation on the sub-card in the dual card, thereby making the state of the dual card after calibration identical to the state of the dual card represented by the DSDA combination 1 of the DSDA emission exclusive mode.

In combination with the above-mentioned priority of DSDA combinations, in other embodiments, the convenience of the terminal device to calibrate the card is combined with the magnitude of the calibration amplitude of the terminal device to calibrate the card, the priority of DSDA combinations is preferentially considered from the convenience of the terminal device to calibrate the card, and the priority of DSDA combinations is considered from the magnitude of the calibration amplitude of the terminal device to the card. For example, if there are 3 DSDA combinations supported by the terminal device at the first location, before performing the calibration operation, it is found that the state of the dual card after performing the calibration operation on one card is the same as the state of the dual card in DSDA combination 1 and DSDA combination 2, the state of the dual card after performing the calibration operation on both cards is the same as the state of the dual card in DSDA combination 3, and therefore, DSDA combination 1 and DSDA combination 2 are taken as candidate DSDA combinations, in DSDA combination 1 and DSDA combination 2, performing the third operation on the sub card may make the state of the dual card after the calibration the same as DSDA combination 1, and performing the second operation on the main card may make the state of the dual card after the calibration the same as DSDA combination 2, and therefore, DSDA combination 1 is taken as the target DSDA combination, and the third operation is performed on the sub card in the dual card so that the state of the dual card after the calibration is the same as the state of the dual card in DSDA combination 1. For a terminal device supporting dual card communication, a network icon (e.g., a 4G icon or a 5G icon) indicating the network status of the dual card is displayed on a graphical user interface (graphical user interface, GUI) of the terminal device. In the above embodiment, if the first operation is performed on any card so that any card resides in the LTE network, the network icon of any card will be affected, as shown in fig. 5, where the network icon of one card is a 4G network, the user will see the 4G icon, know that the user does not experience a good NR network, and the visual experience is reduced.

Therefore, in order to reduce the influence of the user on the visual experience of the 5G icon, the embodiment of the present application proposes to perform a calibration operation on at least one card of the dual cards in case it is determined that the terminal device satisfies the first condition. Wherein the first condition comprises: the terminal equipment is in a screen-off state; or, the foreground application of the terminal device is a full screen application.

That is, before performing the calibration operation on the at least one card, the terminal device may also determine whether the terminal device satisfies the first condition, and in the case where it is determined that the terminal device satisfies the first condition, perform the calibration operation.

It should be appreciated that the order of the steps of determining whether the terminal device satisfies the first condition is not limited in any way, as long as it is determined whether the terminal device satisfies the first condition before the calibration operation is performed on at least one card.

In the embodiment that the first condition includes that the terminal device is in the off-screen state, it means that the user cannot see the content of the screen and cannot see the network icon naturally, so that the visual experience of the user is not affected when the terminal device is in the off-screen state to execute the first operation in the calibration operation.

In embodiments where the first condition includes that the foreground application of the terminal device is a full screen application, then the user is typically not able to see the network icon, so even if the first operation is performed on any card such that the any card resides in the LTE network, the user will not perceive the current network state and therefore will not substantially affect the user's visual experience.

A foreground application is understood to mean an application that is carried out in the system foreground of the terminal, i.e. an application that is currently being used by the user. In general, there may be many applications running simultaneously by the terminal device, but there is usually only one foreground application, and most of the applications run in the background.

A full-screen application may be understood as an application in which an application program started by the terminal device is displayed as a full-screen interface, or in other words, a full-screen application may be understood as an application in which the application program is in a full-screen state. In general, in order to improve the user experience, in a case where the user does not perform a special operation (for example, the foreground application exits from the full screen state), the device state is not displayed on the full screen application, and the device state may include a network icon for indicating the network state, an electric quantity icon for indicating the electric quantity of the device, and the like. However, for other reasons, there are also a small portion of full screen applications that will display device status, which is not within the contemplation of embodiments of the application.

Illustratively, the full screen application may be a camera application, a video player application, a game application, a navigation program, a conference program, and so forth. For example, for camera applications and gaming applications, device status is typically not displayed as long as the application is not exited. For video playback applications, the device status is not displayed as long as the user does not click on the screen.

Since there are many full-screen applications on the market at present, a part of full-screen applications (noted as preset type full-screen applications) may be preset in consideration of practicality and convenience, and whether to execute the calibration operation is determined by taking the part of preset type full-screen applications as a determination condition.

That is, in an embodiment where the first condition includes that the foreground application of the terminal device is a full screen application, the first condition may specifically include: the terminal equipment determines that the foreground application is a preset full-screen application.

The preset class full-screen application may be a full-screen application with high user usage or high user attention, for example. For example, the preset class full screen application may be a higher application in a leader board downloaded by users such as a king, peaceful elite, fantasy west tour, three kingdoms, mind, fire shadow, etc.

In implementation, the preset full-screen application class can be written into a preset list, and whether the foreground application is the preset full-screen application class is determined by determining whether the foreground application is the application in the preset list.

When the terminal device performs the calibration operation on the card, a short service interruption phenomenon may also occur, thereby affecting the user experience. Therefore, in order to reduce the influence of service interruption due to the calibration operation, the embodiment of the present application proposes to perform the calibration operation on at least one card of the dual cards in case it is determined that the terminal device satisfies the second condition. Wherein the second condition comprises any one of:

The business of at least one card has the phenomenon of blocking;

the terminal equipment uses wifi network communication;

the terminal equipment does not currently carry out data service;

the terminal device is currently in a preset scene and the calibration operation is a calibration operation for the secondary card.

That is, before performing the calibration operation on the at least one card, the terminal device may also determine whether the terminal device satisfies the second condition, and in the case where it is determined that the terminal device satisfies the second condition, the calibration operation is performed.

It should be appreciated that the order of the steps of determining whether the terminal device satisfies the second condition is not limited in any way, as long as it is determined whether the terminal device satisfies the second condition before the calibration operation is performed on the at least one card.

In an embodiment in which the second condition includes that the traffic of the at least one card is stuck, the terminal device may weaken the experience of the traffic interruption caused by the calibration operation when performing the calibration operation, and the user may not feel the influence of the calibration operation on the data traffic sharply because the traffic is stuck before the calibration operation is performed, so that the influence of the traffic interruption caused by the calibration operation is reduced.

In an embodiment in which the second condition includes that the terminal device uses wifi network communication, when the terminal device performs the calibration operation, the user does not substantially feel the influence of the change of the cellular mobile data on the data traffic using wifi network, so that the influence of traffic interruption due to the performance of the calibration operation is reduced.

In an embodiment in which the second condition comprises that the terminal device is not currently performing data traffic, the user is substantially unaware of the impact of the change in cellular mobile data on the data traffic when the terminal device performs the calibration operation, so that the impact of traffic interruption due to performing the calibration operation is reduced.

In the embodiment in which the second condition includes that the rate of the data traffic currently performed by the terminal device is smaller than the threshold value, since the rate of the data traffic currently performed is itself low, which means that the current data traffic is not performed smoothly, when the terminal device performs the calibration operation, the user cannot sensitively feel the influence of the calibration operation on the data traffic, so that the influence of the service interruption caused by the performance of the calibration operation is reduced.

In an embodiment in which the second condition comprises that the terminal device is currently in a preset scene, and the calibration operation is a calibration operation for the sub-card, the preset scene represents a scene that has little influence on the user operation by the calibration operation. When the calibration operation is performed on the sub-card, since only the sub-card is affected and the business impact on the main card is small, the calibration operation is performed in consideration of a preset scene that has little impact on the user. The preset scene may be, for example, the following: the application is just opened, or the principals are glowing at the time of the game hall and before the game is played, or the long video application is buffered after the end, etc.

The above embodiment of determining that the terminal device satisfies the first condition to perform the calibration operation and the embodiment of determining that the terminal device satisfies the second condition to perform the calibration operation may be used alone or in combination. When used in combination, that is, in the case where the terminal device satisfies the first condition and the second condition, the terminal device performs a calibration operation.

Fig. 6 is a schematic flow chart of a method 400 of dual card communication provided by an embodiment of the present application. The method 400 may be performed by a terminal device supporting dual card communication, or may be performed by a chip in the terminal device, and embodiments of the present application are not limited in any way. For convenience of description, the method 400 will be described in detail by taking a terminal device as an example.

In S410, the terminal device acquires network information of a first location where the terminal device is currently located, where the network information of the first location is used to indicate a network type and a frequency band supported by the first location.

For a specific description of the network type and the frequency band supported by the first location, reference may be made to the above related description, and no further description is given.

In this step, the terminal device obtains the network information of the first location in various manners, and the embodiment of the present application is not limited in any way.

In some embodiments, the acquiring the network information of the first location where the terminal device is currently located includes:

the network information of the first position is obtained from a cloud end, and the network information of a plurality of positions including the first position is stored in the cloud end.

The combination of network information for a plurality of locations can be regarded as a communication map as shown in fig. 4, which includes a plurality of grids each representing a location, and in which the network types and frequency bands supported by the corresponding location are recorded. For a specific description of the communication map, reference may be made to the above related description, and no detailed description is given.

The cloud end serves as a network server, can generate and store network information of more positions, and is convenient for the terminal equipment to acquire the network information of more positions, so that the terminal equipment is in a DSDA mode as far as possible at different positions, and user experience is improved.

In an example, the network information for the plurality of locations is generated based on network crowdsourcing. For a specific description of network crowdsourcing, reference may be made to the relevant description above, and no further description is given.

Because the network crowdsourcing mode can mobilize a large number of users to collect network data so as to generate network information of different positions, the cloud can generate and store network information of more positions, and because the network information is generated by utilizing the network data provided by a large number of users, the cost in the aspect of manpower is greatly reduced.

In other embodiments, the terminal device may obtain the network information of the first location from the local information.

The local information indicates information stored in the terminal device and is related to data of a specific user only, and therefore, the local information includes not much network information of a location, which is generally the network information of a location where a specific user has previously gone, for example, a location such as a home, a company, a teaching building, a mall, a cafe, a hospital, etc.

In S420, in case that the dual card dual pass DSDA mode is not formed between the first card and the second card of the terminal device, the terminal device determines at least one DSDA combination capable of forming the DSDA mode supported by the terminal device at the first location according to the network information of the first location, each DSDA combination including a network type and a frequency band of each card of the dual cards.

In this step, in the case where the DSDA pattern is not formed between the first card and the second card, the terminal device traverses the network type and the frequency band indicated by the network information of the first location according to the DSDA combination supported by the terminal device itself and the network information of the first location obtained from S410, determines whether there is a DSDA combination supported by the terminal device at the first location, and if there is, also determines the specific content of the DSDA combination supported by the terminal device at the first location, that is, determines at least one DSDA combination supported by the terminal device at the first location.

For example, the network type indicated by the network information of the first location includes an NR-SA network and an LTE network, the frequency band includes frequency bands indicated by n41, n1, n78, B1, B3, and B41, and 3 DSDA combinations of the network information of the first location are DSDA combination 1: NR SA n1+NR SA n1, DSDA combination 2: NR SA n1+ NR SA n78, DSDA combination 3: nrsan41+lte b1. If the DSDA combination supported by the terminal device is nrsn41+lte b1, which is the same as DSDA combination 3 in the network information of the first location, there is a DSDA combination supported by the terminal device at the first location, which is DSDA combination 3. If the DSDA combination supported by the terminal device is nrsn41+lte b3, which is different from any DSDA combination in the network information of the first location, there is no DSDA combination supported by the terminal device at the first location.

The at least one DSDA combination includes one or more DSDA combinations. If there is only one DSDA combination supported by the terminal device at the first location, the at least one DSDA combination is the unique DSDA combination. If there are a plurality of DSDA combinations supported by the terminal device at the first location, the at least one DSDA combination is a plurality of DSDA combinations.

The DSDA combinations supported by the same terminal device are fixed (independent of the location of the terminal device), and the DSDA combinations supported by different terminal devices may be the same or different, and may be specifically determined according to the model or hardware information of the terminal device. In an implementation, dual card mode information may be preconfigured in the terminal device, the dual card mode information being used to indicate respective combinations of card modes supported by the terminal device, including all DSDA combinations supported by the terminal device, as shown in table 1 above.

The DSDA combinations supported by the same terminal device at different locations may be the same or different, depending mainly on the network type and frequency band supported by the respective locations.

It should be understood that before S420, the terminal device determines whether a DSDA mode is formed between the first card and the second card, and if it is determined that a DSDA mode is not formed between the first card and the second card, S420 is performed.

In S430, the terminal device performs a calibration operation on at least one card of the first card and the second card according to a target DSDA combination of the at least one DSDA combination, so that a network type and a frequency band of the first card and the second card are the same as a network type and a frequency band of a dual card of the target DSDA combination.

That is, the terminal device performs a calibration operation on one or both of the first card and the second card according to a predetermined target DSDA combination capable of causing the first card and the second card to form a DSDA mode at the first position, so that the states of the first card and the second card after performing the calibration operation are the same as the states of the two cards in the target DSDA combination. It should be understood that the status of the card described herein indicates the network type and frequency band of the card.

In some embodiments, if the frequency band where either of the first card and the second card resides does not meet the frequency band of a card in the target DSDA combination, then a third operation is performed on either card according to the target DSDA combination. The description of the specific examples may refer to the related descriptions above, and will not be repeated.

In other embodiments, if the network type and the frequency band of the network where either one of the first card and the second card resides do not satisfy the network type and the frequency band of a certain card in the target DSDA combination, the first operation or the second operation may be performed on either one of the cards, and if after the first operation or the second operation is performed, the frequency band where either one of the cards resides does not satisfy the frequency band of a certain card in the target DSDA combination, the third operation may be performed on either one of the cards. The description of the specific examples may refer to the related descriptions above, and will not be repeated.

In other embodiments, if the network type and the frequency band of the network where the first card and the second card reside do not satisfy the network type and the frequency band of the dual card in the target DSDA combination, the first operation or the second operation may be performed on each card, and if the frequency band where at least one card resides after performing the first operation or the second operation does not satisfy the frequency band of at least one card in the target DSDA combination, the third operation may be performed on at least one card. The description of the specific examples may refer to the related descriptions above, and will not be repeated.

In some embodiments, the calibration operation of any one of the at least one card includes at least one of:

a second operation for causing the any one card to reside in the new wireless NR network;

and a third operation of recording the frequency band where the any card currently resides in the blacklist of the first position, so that the terminal equipment reselects the frequency band for any card to reside.

It should be understood that either of the cards described above is either the first card or the second card.

In some embodiments, the first operation comprises: an operation of turning off the NR network of any one card or an operation of lowering the priority of the NR network of any one card.

In an example, the first operation includes an operation to decrease a priority of the NR network of the any card; and the first operation further includes an operation of suppressing the B1 event measurement by the any one card.

In some embodiments, the second operation comprises: operation of opening the NR network of any one card.

For specific descriptions of the calibration operation, the first operation, the second operation, the third operation, and the blacklist, reference may be made to the related descriptions above, and the detailed descriptions are omitted.

In some embodiments, in a case where the dual card dual pass DSDA mode is not formed between the first card and the second card of the terminal device, before determining at least one DSDA combination capable of forming the DSDA mode supported by the terminal device at the first location according to the network information of the first location, the method 400 further includes:

when the location of the terminal device changes, it is determined whether a DSDA mode is formed between the first card and the second card.

That is, before S420 is performed, the terminal device detects whether the location of the terminal device is changed, and if it is detected that the location of the terminal device is changed, it is determined whether a DSDA mode is formed between the first card and the second card, and if it is determined that the DSDA mode is not formed between the first card and the second card, S420 is performed.

It will be appreciated that in this embodiment the terminal device will not only detect that it is in a change of location, but will also detect that it is currently in a first location where it determines whether a DSDA mode is formed between the first card and the second card.

In some embodiments, the at least one DSDA combination comprises a plurality of DSDA combinations; and, prior to the performing a calibration operation on at least one of the first card and the second card according to the target DSDA combination of the at least one DSDA combination, method 400 further comprises:

the DSDA combination with the highest priority among the plurality of DSDA combinations is determined as the target DSDA combination.

That is, in the case where the DSDA combinations supported by the terminal device at the first location include a plurality of DSDA combinations, the terminal device selects the DSDA combination having the highest priority as the target DSDA combination according to the priorities of the plurality of DSDA combinations, so that a calibration operation is performed on at least one card of the first card and the second card according to the target DSDA combination such that the states of the first card and the second card are the same as the states of the two cards represented by the target DSDA combination.

In some embodiments, the highest priority DSDA combination is the best capable combination of dual card modes of the plurality of DSDA combinations.

This embodiment defines DSDA combining priority from the capabilities of the dual card mode. The better the capability of the dual card mode, the higher the priority of the DSDA combination, whereas the worse the capability of the dual card mode, the lower the priority of the DSDA combination. The capability of the dual card mode is from high to low: DSDA transmission exclusive sharing > DSDA transmission sharing > DR-DSDS > DSDS, then the priority of the DSDA combination from high to low may be: DSDA transmission exclusive share > DSDA transmission shared > DR-DSDS > DSDS.

In other embodiments, the highest priority DSDA combination is the combination having the smallest calibration amplitude when performing a calibration operation on the at least one card based on each of the plurality of DSDA combinations. That is, the priority of the DSDA combination may be defined from the magnitude of the calibration amplitude of the terminal device to the card, and the detailed description may refer to the related description above, which is not repeated.

According to the dual-card communication method provided by the embodiment of the application, the combination with the smallest calibration amplitude is used as the DSDA combination with the highest priority when the terminal equipment in the plurality of DSDA combinations executes the calibration operation on at least one card, the terminal equipment can execute the calibration operation on at least one card in the first card and the second card in a mode with the smallest calibration amplitude, the adjustment on the current state of the terminal equipment is the smallest, the implementation is convenient, the user is not easy to perceive the change state of the equipment, and the user experience is improved.

In other embodiments, the highest priority DSDA combination is a DSDA combination that is most convenient when performing calibration operations on the at least one card based on each of the plurality of DSDA combinations. That is, the priority of the DSDA combination may be defined from the level of the convenience of the terminal device to calibrate the card, and the specific description may refer to the above related description, which is not repeated.

According to the dual-card communication method provided by the embodiment of the application, the DSDA combination with the highest convenience in executing the calibration operation on at least one card in the plurality of DSDA combinations is used as the DSDA combination with the highest priority, and the terminal equipment executes the calibration operation on at least one card in the first card and the second card according to the DSDA combination with the highest priority, so that the convenience in operation is facilitated.

The priorities of the DSDA combinations exemplified above may be used alone or in combination, and the embodiments of the present application are not limited in any way. In addition, for a specific description of the priority of the combination of DSDA as described above, reference may be made to the above related description, and the description is not repeated.

In some embodiments, the method 400 further comprises, prior to performing the calibration operation on at least one of the first card and the second card according to a target DSDA combination of the at least one DSDA combination:

determining that the terminal device meets a first condition, the first condition comprising: the terminal equipment is in a screen-off state; or, the foreground application of the terminal device is a full screen application.

That is, the terminal device determines whether the terminal device satisfies the first condition before performing the calibration operation, and performs the calibration operation in the case where it is determined that the terminal device satisfies the first condition. For the specific description of the first condition, reference may be made to the above related description, and no further description is given.

In the dual-card communication method provided by the embodiment of the application, when the calibration operation includes the first operation that the user makes any one card be in the LTE network, if the first operation is executed on any one card, the any one card is caused to reside in the LTE network, and the 4G icon is displayed on the screen, so that the visual experience of the user is affected. In the embodiment of the application, the first condition is associated with the display of the network icon, if the first condition includes that the terminal equipment is in the off-screen state, the user cannot see the content of the screen or the network icon, so that after the first operation in the calibration operation is executed in the off-screen state of the terminal equipment, the user cannot see the 4G icon, and the visual experience of the user cannot be influenced. If the first condition includes that the foreground application of the terminal device is a full screen application, then the user cannot see the network icon in general, so even if the first operation in the calibration operation is performed on any card so that any card resides in the LTE network, the user cannot see the 4G icon, and therefore the visual experience of the user is not substantially affected.

determining that the terminal device satisfies a second condition, the second condition comprising any one of:

the at least one card service is stuck;
