Patent Description:
Generally, multi-card user equipment (UE) may camp on many different cells. Take dual-card UE as an example. For example, one card may camp on one cell, and the other card may camp on another cell. Specifically, one way for the dual-card UE to transmit data is that the two cards may camp on different cells separately and transmit data simultaneously through the respective cells they camp on. The other way is that the two cards may camp on different cells separately and transmit data by means of time division; that is, in one period of time, one card transmits data through the cell it camps on, and in another period of time, another card transmits data through the cell it camps on.

However, as multi-card UE camps on multiple different cells, on the one hand, the signal quality of these cells may vary, for example, the signal quality of some cells is good while the signal quality of some other cells is not so good, which results in good communications quality of a card camping on some cells and poor communications quality of a card camping on some other cells; on the other hand, some of these cells may be in a state of barring access, in this case, the multiple cards need to determine the state of multiple cells when accessing the multiple cells, which will lead to unstable communications performance of the multi-card UE.

D1 (<CIT>) discloses a method for operating a multi-SIM mobile device. The method includes determining whether at least one Registered Public Land Mobile Network (RPLMN) among a first RPLMN of a first SIM and a second RPLMN of a second SIM of the multi-SIM mobile device is unavailable to the multi-SIM mobile device when the multi-SIM mobile device triggers a Public Land Mobile Network (PLMN) search, identifying a common PLMN, from a first PLMN set associated with the first SIM and a second PLMN set associated with the second SIM, in response to determining that the at least one RPLMN among the first RPLMN and the second RPLMN is unavailable, and camping on the common PLMN by the first SIM and the second SIM after acquiring camping information of the common PLMN.

D2 (<CIT>) discloses a communication method for a dual SIM, dual standby and single-pass terminal. The communication method comprises: receiving a call request corresponding to a first SIM card, reading registration information of the first SIM card in a first memory region, and establishing a call connection according to the read registration information of the first SIM card; reading registration information of a second SIM card in the first memory region, the second SIM card and the first SIM card corresponding to the same operator identifier, and detecting, according to the registration information of the second SIM card, a call request corresponding to the second SIM card; and generating, according to the call request corresponding to the second SIM card, prompt information as to whether a switch is to be performed.

The embodiments of the present application provide an information sharing method and user equipment, which can resolve the problem of unstable communications performance of multi-card UE when the multi-card UE camps on multiple different cells.

In order to resolve the foregoing technical problem, the embodiments of the present application utilizes the following technical solutions:.

According to a first aspect of the embodiments of the present application, an information sharing method applied to UE is provided, which is defined in claim <NUM>.

According to a second aspect of the embodiments of the present application, UE is provided, which is defined in claim <NUM>.

According to a third aspect of the embodiments of the present application, a computer readable storage medium is provided, which is defined in claim <NUM>.

In the specification and claims of the embodiments of this application, the terms such as "first" and "second" are used to distinguish between different objects, but are not used to describe a particular sequence of the objects. For example, a first SIM card, a second SIM card, and the like are used to distinguish between different SIM cards, but are not used to describe a particular sequence of the SIM cards.

In the description of the embodiments of this application, unless otherwise specified, the meaning of "a plurality of" means two or more. For example, multiple elements refer to two elements or more than two elements.

The term "and/or" in this specification describes an association relationship of associated objects, indicating that three relationships may exist. For example, a display panel and/or a backlight may indicate three cases: only the display panel exists, both the display panel and the backlight exist, and only the backlight exists. A character "/" in this specification indicates an "or" relationship between associated objects. For example, input/output indicates input or output.

In the embodiments of this application, the term such as "exemplary" or "for example" is used to indicate an example, an instance, or a description. Any embodiment or design scheme described as "exemplary" or "an example" in the embodiments of this application should not be construed as being preferable or advantageous than other embodiments or design schemes. Specifically, the words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

The following describes some concepts and/or terms related in an information sharing method and user equipment provided in the embodiments of the present application.

System information (System Information, SI) may include: a master information block (Master Information Block, MIB) and a system information block (System Information Block, SIB).

The foregoing MIB and SIB are always broadcast periodically. A broadcast cycle of the MIB is a fixed cycle, and a broadcast cycle of the SIB may be a different cycle configured by a network device. The SIB may include system information such as SIB1-SIB20, and it is sure that it may be subject to be continuous extension in the future, which is not limited in the embodiments of the present application.

The MIB may be dispensed together with a synchronous signal (Synchronous Signal, SS) block to UE, and the MIB may include scheduling information for remaining system information (Remaining System Information, RMSI). The RMSI is some necessary system information for the UE to work in a certain cell, which is similar to, for example, SIB1 and SIB2 in a long term evolution (Long Term Evolution, LTE) system, and the RMSI may include scheduling information for other SI.

The other system information (OSI, Other SI): system information that supports other auxiliary functions, which is similar to, for example, an earthquake and tsunami warning system (Earthquake and Tsunami Warning System, ETWS) and commercial mobile alert service (Commercial Mobile Alert Service, CMAS) in an LTE system, or another system information.

The system information may include bar information (that is, bar information) of some cells. For example, the bar information of a cell may include: information used to indicate that a certain cell is barred; or, information used to indicate that a frequency of a certain cell is barred; an identifier of a closed subscriber group corresponding to a certain cell; and an identifier of a cell type corresponding to a certain cell.

The embodiments of the present application provide an information sharing method and user equipment, where the UE may obtain first information by using a first SIM card (the first information is information sent by a network device of a second SIM card and received by the second SIM card), and control the first SIM card according to the first information. As the first SIM card can share the first information with the second SIM card (that is, the information sent by the network device of the second SIM card to the second SIM card), the UE can control the first SIM card according to the first information, so that the first SIM card accesses a cell with almost the same signal quality as that of a cell accessed by the second SIM card, or the first SIM card does not need to judge a state of some cells after the second SIM card judges the state of some cells. In this way, stability of the communications performance of the multi-card UE can be enhanced.

The information sharing method and the user equipment according to the embodiments of the present application may be applied to a communications system. Specifically, it may be applied to a process in which at least two SIM cards (such as the first SIM card and the second SIM card) of the multi-card UE share the first information of the second SIM card and control the first SIM card according to the first information based on the communications system.

<FIG> shows a schematic architectural diagram of a communications system according to an embodiment of the present application. As shown in <FIG>, the communications system may include UE <NUM> and a network device <NUM>. The UE <NUM> and the network device <NUM> may establish a connection and communicate with each other.

It should be noted that in this embodiment of the present application, the UE <NUM> and the network device <NUM> as shown in <FIG> may be connected wirelessly. To show a connection relationship between the UE <NUM> and the network device <NUM> more clearly, a solid line as shown in <FIG> is used to show the connection relationship between the UE <NUM> and the network device <NUM>.

Optionally, in the embodiment of the present application, the foregoing network device <NUM> may be a network device of the second SIM card or a network device of the first SIM card.

UE is a device providing voice and/or data connectivity to a user, a handheld device having a wired/wireless connection function, or other processing device connected to a wireless modem. The UE may communicate with one or more core network devices through a radio access network (Radio Access Network, RAN). The UE may be a mobile terminal such as a mobile phone (or referred to as a "cellular" phone) or a computer having a mobile terminal, or may be a portable, pocket-sized, handheld, computer built-in, or vehicle-mounted mobile apparatus, which exchanges language and/or data with the RAN. For example, the mobile apparatus is a device such as a personal communication service (Personal Communication Service, PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, or a personal digital assistant (Personal Digital Assistant, PDA) and so on. The UE may be alternatively referred to as a user agent (User Agent) or a terminal device.

The network device may be a base station. The base station is an apparatus deployed in the RAN to provide a wireless communication function for the UE. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, names of devices having base station functions may be different. For example, in a 3rd generation mobile communications (<NUM>-Generation, <NUM>) network, the device is referred to as a NodeB (NodeB); in an LTE system, the device is referred to as an evolved NodeB (evolved NodeB, eNB or eNodeB); and in a 5th generation mobile communications (<NUM>) network, the device is referred to as a gNB. With evolution of the communications technology, the name of the "base station" may change.

The following describes in detail an information sharing method and user equipment provided by the embodiments of the present application through specific embodiments and application scenarios with reference to the accompanying drawings.

Based on a communications system as shown in <FIG>, an embodiment of the present application provides an information sharing method. As shown in <FIG>, the information sharing method may include the following steps <NUM> and <NUM>.

Step <NUM>: UE obtains first information by using a first SIM card.

In this embodiment of the present application, the foregoing first information is information sent by a network device of a second SIM card and received by the second SIM card.

In this embodiment of the present application, the UE may include at least two SIM cards. The first SIM card and the second SIM card are different SIM cards among the at least two SIM cards.

Optionally, in this embodiment of the present application, the foregoing first SIM card and the second SIM card belong to a same operator.

It should be noted that in this embodiment of the present application, the foregoing first SIM card may be one SIM card different from the second SIM card among the at least two SIM cards; or, the foregoing first SIM card may be another SIM card other than the second SIM card among the at least two SIM cards.

It can be understood that if the first SIM card is one SIM card different from the second SIM card among the at least two SIM cards, the one SIM card and the second SIM card share the first information; if the first SIM card is another SIM card other than the second SIM card among the at least two SIM cards, the another SIM card and the second SIM card share the first information (that is, all SIM cards among the at least two SIM cards share the first information).

Optionally, in this embodiment of the present application, a state of the foregoing second SIM card may be idle state (Idle), inactive state (Inactive), or connected state.

Optionally, in this embodiment of the present application, the foregoing second SIM card may be a primary card of the UE, and the first SIM card may be a secondary card of the UE.

In all embodiment of the present invention, the foregoing first information includes any one of the following: dedicated configuration information and specific information in system information.

Optionally, in this embodiment of the present application, the foregoing first information may further include any one of the following: system information and cell reselection information.

In this embodiment of the present application, the foregoing dedicated configuration information may be used to indicate a serving cell of the second SIM card that is in connected state, or a priority of a camping frequency of the second SIM card that is in idle state; the foregoing system information may be used to instruct the second SIM card to select a cell or to reselect a cell; the foregoing cell reselection information may be used to instruct the second SIM card to reselect a cell; and the foregoing specific information in system information may be used to indicate that at least one first cell is in a state of barring access, and a cell selected or reselected by the second SIM card is a cell in the at least one first cell.

It should be noted that a camping frequency of the second SIM card may be understood as: a frequency of a cell where the second SIM card camps on.

Alternatively, in the embodiment of the present application, the foregoing specific information in system information may include at least one of the following A, B, C, D and E.

A: barring information of the at least one first cell, where the foregoing at least one first cell is a serving cell of the second SIM card, or a cell of a first cell type in a public land mobile network (Public Land Mobile Network, PLMN) corresponding to a network device of the second SIM card.

It should be noted that the serving cell of the foregoing second SIM card may be understood as a cell where the network device of the second SIM card provides services.

Optionally, in this embodiment of the present application, the foregoing first cell type may be a new radio (New Radio, NR) cell type.

It may be understood that the barring information of the foregoing at least one first cell may be used to indicate that the serving cell of the second SIM card is in a state of barring access; or the barring information of the foregoing at least one first cell may be used to indicate that the cell of the first cell type in the PLMN corresponding to the network device of the second SIM card is in a state of barring access.

B: barring information of a first frequency, where the foregoing at least one first cell is a cell corresponding to the first frequency.

It may be understood that the foregoing first frequency is a frequency of the at least one first cell.

It may be understood that the foregoing barring information of the first frequency may be used to indicate that a cell corresponding to the first frequency is in a state of barring access.

C: an identifier of a cell type, where the foregoing at least one first cell is a cell of this cell type among serving cells of the second SIM card.

For example, if identifiers of cell types included in the foregoing specific information are type <NUM>, type <NUM> and type <NUM> respectively, the serving cells for the second SIM card are cell <NUM> to cell <NUM> respectively, and cell types corresponding to the cell <NUM> to cell <NUM> are type <NUM> to type <NUM> respectively, the at least one first cell is cell <NUM> to cell <NUM>.

It may be understood that the foregoing identifier of a cell type may be used to indicate that a cell of this cell type among serving cells of the second SIM card is in a state of barring access.

D: an identifier of a closed subscriber group (Closed Subscriber Group, CSG), where the foregoing at least one first cells is a cell belonging to the CSG.

It may be understood that the foregoing closed subscriber group includes at least one first cell.

It may be understood that the foregoing identifier of a closed subscriber group may be used to indicate that a cell belonging to the closed subscriber group is in a state of barring access.

E: an identity of the at least one first cell, where the foregoing at least one first cell is a cell that allows another UE to access.

It may be understood that the foregoing identifier of the at least one first cell may be used to indicate that the cell that allows another UE to access is in a state of barring access.

In this embodiment of the present application, the foregoing step <NUM> may be specifically implemented by using the following steps 201a to 201d, as shown in <FIG> in combination with <FIG>.

Step 201a: the network device of the second SIM card sends the first information to the second SIM card of the UE.

Step 201b: the second SIM card of the UE receives the first information, and reads the first information.

Step 201c: the UE saves the first information in a shared area.

Step 201d: the first SIM card of the UE reads the first information in the shared area.

In this embodiment of the present application, the foregoing shared area is an area where the first SIM card and the second SIM card share information.

Optionally, in this embodiment of the present application, the foregoing shared area may be an area where at least two SIM cards share information.

It may be understood that after the network device of the second SIM card sends the first information to the second SIM card, the second SIM card may read the first information, and then the UE may store the first information read by the second SIM card in the shared area in the UE, so that the first SIM card can read the first information from the shared area.

In this embodiment of the present application, the foregoing step <NUM> may be specifically implemented by using the following steps 201a, step 201b, step 201e, and step 201f, as shown in <FIG> in combination with <FIG>.

Step 201e: the second SIM card of the UE sends the first information to the first SIM card of the UE.

Step 201f: the first SIM card of the UE receives the first information.

It may be understood that after the network device of the second SIM card sends the first information to the second SIM card, the second SIM card may read the first information and send the read first information to the first SIM card.

In this embodiment of the present application, the first SIM card may share the first information of the second SIM card by means of reading the first information in the shared area or by means of receiving the first information sent by the second SIM card.

Optionally, in this embodiment of the present application, the foregoing step <NUM> may be specifically implemented by using the following step <NUM>.

Step <NUM>: the UE obtains the first information by using the first SIM card in the case that the first SIM card selects a cell or reselects a cell.

In this embodiment of the present application, the foregoing selecting a cell by the first SIM card may be understood as a process of selecting a cell to camp on in the case that the first SIM card has not yet camped on a cell. The foregoing reselecting a cell by the first SIM card may be understood as a process of reselecting another cell to camp on in the case that the first SIM card leaves a cell it has camped on. The first SIM card reselects a cell in the case that it is in idle state (that is, the first SIM card in idle state reselects a cell).

It should be noted that for a specific method for "obtaining the first information by the UE by using the first SIM card" in the foregoing step <NUM>, reference may be made to the relevant description from step 201a to step 201f in the foregoing embodiment, which is no longer repeated here.

Optionally, in this embodiment of the present application, the UE may also obtain the first information by using the first SIM card in the case that the first SIM card performs another action.

Step <NUM>. The UE controls the first SIM card according to the first information.

Alternatively, in this embodiment of the present application, the UE may control the first SIM card to access one cell (such as a second cell or a third cell described in the following embodiment) or control the first SIM card not to access the at least one first cell (the at least one first cell is in a state of barring access) according to the first information.

It may be understood that the foregoing first information is information sent to the second SIM card by the network device of the second SIM card. The first SIM card may share the first information with the second SIM card, so that the UE can control the first SIM card according to the first information.

Optionally, in one possible implementation manner for this embodiment of the present application, the foregoing first information includes dedicated configuration information. The foregoing step <NUM> may be implemented by using the following step 202a1 or step 202a2, as shown in <FIG> in combination with <FIG>.

Step 202a1. The UE controls the first SIM card to access a second cell according to the first information in the case that the second SIM card is in connected state.

In this embodiment of the present application, the foregoing second cell is a serving cell of the second SIM card.

It may be understood that the signal quality of the serving cell of the second SIM card is good in the case that the second SIM card is in connected state, and the UE may control the first SIM card to access the serving cell of the second SIM card with good signal quality according to dedicated configuration information (the dedicated configuration information is used to indicate the serving cell of the second SIM card that is in connected state).

Optionally, in this embodiment of the present application, the foregoing second cell may be a primary serving cell of the second SIM card.

It may be understood that in the case that the second SIM card is in connected state, the signal quality of the primary serving cell of the second SIM card is the best compared with other serving cells of the second SIM card (that is, serving cells other than the primary serving cell of the second SIM card among serving cells of the second SIM card). The UE may control the first SIM card to access the primary serving cell of the second SIM card with the best signal quality according to the dedicated configuration information.

In this embodiment of the present application, as the signal quality of the serving cell of the second SIM card is good in the case that the second SIM card is in connected state, the UE controls the first SIM card to access the second cell (that is, the serving cell of the second SIM card) according to the dedicated configuration information obtained by using the first SIM card (the dedicated configuration information is used to indicate a serving cell of the second SIM card that is in connected state). In this way, the first SIM card can access a cell with good signal quality, thereby ensuring that both the first SIM card and the second SIM card can access a cell with good signal quality, and enhancing stability of communications quality of the multi-card UE.

Step 202a2. The UE controls the first SIM card to preferentially access a second frequency according to the first information in the case that the second SIM card is in idle state.

In this embodiment of the present application, the foregoing second frequency is a frequency with the highest priority among camping frequencies of the second SIM card.

It may be understood that in the case that the second SIM card is in idle state, the UE may determine the frequency with the highest priority among the camping frequencies of the second SIM card according to dedicated configuration information (the dedicated configuration information is used to indicate priorities of the camping frequencies of the second SIM card), and then control the first SIM card to access the frequency first (that is, the second frequency).

Exemplarily, it is assumed that the camping frequencies of the second SIM card in idle state are frequency <NUM> to frequency <NUM>. The UE determines that the frequency with the highest priority among the camping frequencies of the second SIM card is frequency <NUM> according to dedicated configuration information (for example, the dedicated configuration information is used to indicate that a priority of frequency <NUM> is higher than that of frequency <NUM>, and a priority of frequency <NUM> is higher than that of frequency <NUM>), and then the UE controls the first SIM card to preferentially access frequency <NUM> first.

In this embodiment of the present application, as the UE may control, in the case that the second SIM card is in idle state, the first SIM card to preferentially access the second frequency (that is, the frequency with the highest priority among the camping frequencies of the second SIM card) according to the dedicated configuration information which indicates the priorities of the camping frequencies of the second SIM card. In this way, the first SIM card can preferentially access the frequency with a high priority, thereby enhancing stability of the communications quality of the multi-card UE.

Optionally, in another possible implementation manner for this embodiment of the present application, the foregoing first information includes system information or cell reselection information. The foregoing step <NUM> may be implemented by using the following step 202b, as shown in <FIG> in combination with <FIG>.

The UE controls the first SIM card to access a third cell according to the first information.

In this embodiment of the present application, the foregoing third cell is a cell selected or reselected by the second SIM card.

It may be understood that in the case that the first information includes system information (the system information is used to instruct the second SIM card to select or reselect a cell), the first information shared by the first SIM card is the system information that instructs the second SIM card to select or reselect a cell. In this case, the UE controls the first SIM card to directly access the third cell (that is, the cell selected or reselected by the second SIM card) rather than controls the first SIM card to perform the process of selecting or reselecting a cell.

It may be understood that in the case that the first information includes cell reselection information (the cell reselection information is used to instruct the second SIM card to reselect a cell), the first information shared by the first SIM card is the cell reselection information that instructs the second SIM card to reselect a cell. In this case, the UE controls the first SIM card to directly access the third cell (that is, the cell reselected by the second SIM card) rather than controls the first SIM card to perform the process of reselecting a cell.

It may be understood that in this embodiment of the present application, in the case that the first information includes system information or cell reselection information, the UE may control the first SIM card to access a same cell as the second SIM card (for example, the cell accessed by the second SIM card is a cell selected by the second SIM card, or a cell reselected by the second SIM card). The first SIM card and the second SIM card that access the same cell achieve almost the same communications quality.

In this embodiment of the present application, the UE may control the first SIM card to access the third cell (that is, the cell selected or reselected by the second SIM card) according to the system information (the system information is used to instruct the second SIM card to select or reselect a cell) or the cell reselection information (the cell reselection information is used to instruct the second SIM card to reselect a cell) obtained by using the first SIM card. In this way, the first SIM card can access the same cell as the second SIM card, so that the communications quality of the first SIM card and the second SIM card is the same, thereby enhancing stability of the communications quality of the multi-card UE.

Optionally, in another possible implementation manner for this embodiment of the present application, the foregoing first information includes specific information in system information. The foregoing step <NUM> may be implemented by using the following step 202c as shown in <FIG> in combination with <FIG>.

The UE controls the first SIM card not to access the at least one first cell according to the first information.

Optionally, in this embodiment of the present application, the at least one first cell in the foregoing step 202c may include at least one of the following: a serving cell of the second SIM card, a cell corresponding to a first frequency, a cell of a cell type among serving cells of the second SIM card, a cell belonging to a closed subscriber group, and a cell that allows another UE to access.

It may be understood that in the case that the first information includes the specific information in system information (the specific information is used to indicate that the at least one first cell is in a state of barring access), the first SIM card and the second SIM card share the specific information that indicates the at least one first cell is in a state of barring access, that is, the first SIM card can learn that the at least one first cell is in a state of barring access. In this case, the UE may control the first SIM card not to access the at least one first cell.

In this embodiment of the present application, as the specific information in system information is used to indicate that the at least one first cell is in a state of barring access, the UE controls the first SIM card not to access the at least one first cell according to the specific information obtained by using the first SIM card, which can prevent the first SIM card from performing the process of selecting or reselecting a cell in the at least one first cell (for example, judging a state of the at least one first cell) in the case of not knowing that the at least one first cell is in a state of barring access. In this way, the waste of a communications resource can be avoided, and stability of the communication performance of the multi-card UE can be enhanced.

This embodiment of the present application provides an information sharing method, where UE may obtain first information by using a first SIM card (the first information is information sent by a network device of a second SIM card and received by the second SIM card), and control the first SIM card according to the first information. As the first SIM card can share the first information with the second SIM card (that is, the information sent by the network device of the second SIM card to the second SIM card), the UE can control the first SIM card according to the first information, so that the first SIM card accesses a cell with almost the same signal quality as that of a cell accessed by the second SIM card, or the first SIM card does not need to judge a state of some cells after the second SIM card judges the state of some cells. In this way, stability of the communications performance of the multi-card UE can be enhanced.

Optionally, in this embodiment of the present invention, before the foregoing Step <NUM>, the information sharing method provided in this embodiment of the present invention may further include the following Step <NUM>, and the foregoing Step <NUM> may be specifically implemented by using the following Step 202d as shown in <FIG> in combination with <FIG>.

Step <NUM>. The UE obtains indication information.

In this embodiment of the present invention, the foregoing indication information is used to indicate whether the first SIM card is allowed to use information of the second SIM card.

Optionally, in this embodiment of the present invention, the foregoing indication information may be used to indicate whether the first SIM card is allowed to access a serving cell of the second SIM card that is in connected state.

Optionally, in this embodiment of the present application, the foregoing indication information may be used to indicate whether the first SIM card is allowed to access a cell selected by the second SIM card.

Optionally, in this embodiment of the present application, the foregoing indication information may be used to indicate whether the first SIM card is allowed to access a cell reselected by the second SIM card.

Optionally, in this embodiment of the present application, the foregoing indication information may be used to indicate whether the first SIM card is allowed to use specific information in system information.

Optionally, in this embodiment of the present application, the foregoing indication information may be predefined, or configured by a network device.

Optionally, in this embodiment of the present application, the foregoing indication information may be predefined by a subscriber.

The UE controls the first SIM card according to the first information in the case that the indication information indicates that the first SIM card is allowed to use information of the second SIM card.

It should be noted that for a specific method for "controlling the first SIM card by the UE according to the first information" in the foregoing step 202d, reference may be made to the relevant description of step <NUM>, step 202a1, step 202a2, step 202b and step 202c in the foregoing embodiment, which is no longer repeated here.

In this embodiment of the present application, in the case that the indication information indicates that the first SIM card is allowed to use information of the second SIM card, the UE may control the first SIM card according to the first information, so that the first SIM card accesses a cell with almost the same signal quality as that of a cell accessed by the second SIM card, or the first SIM card does not need to judge a state of some cells after the second SIM card judges the state of some cells. In this way, stability of the communications performance of the multi-card UE can be enhanced.

It should be noted that in this embodiment of the present application, the foregoing <FIG> are illustrated in combination with <FIG>, which does not form any limitation on the embodiments of the present application. It may be understood that in an actual implementation, the foregoing <FIG> may also be implemented in combination with any other figures that can be combined.

<FIG> shows a possible schematic structural diagram of UE related in an embodiment of the present application, where the UE includes at least two SIM cards. As shown in <FIG>, UE <NUM> provided by an embodiment of the present application may include: an acquisition unit <NUM> and a control unit <NUM>.

The acquisition unit <NUM> is configured to obtain first information by using a first SIM card, where the first information is information sent by a network device of a second SIM card and received by the second SIM card. The control unit <NUM> is configured to control the first SIM card according to the first information obtained by using the acquisition unit <NUM>. The first SIM card and the second SIM card are different SIM cards among the at least two SIM cards.

In all embodiments of the present invention, the foregoing first information includes any one of the following: dedicated configuration information and specific information in system information. In a possible implementation manner, the foregoing first information may further include any one of the following: system information and cell reselection information. The dedicated configuration information is used to indicate a serving cell of the second SIM card that is in connected state, or a priority of a camping frequency of the second SIM card that is in idle state; the system information is used to instruct the second SIM card to select a cell or to reselect a cell; the cell reselection information is used to instruct the second SIM card to reselect a cell; the specific information in system information is used to indicate that at least one first cell is in a state of barring access, and a cell selected or reselected by the second SIM card is a cell in the at least one first cell.

In a possible implementation manner, the foregoing specific information may include at least one of the following A, B, C, D and E. A: barring information of the at least one first cell, where the at least one first cell is a serving cell of the second SIM card, or a cell of a first cell type in a PLMN corresponding to a network device for the second SIM card. B: barring information of a first frequency, where the foregoing at least one first cell is a cell corresponding to the first frequency. C: an identifier of a cell type, where the foregoing at least one first cell is a cell of this cell type among serving cells of the second SIM card.
