[0005] In traditional multi-SIM wireless communication devices, when a wireless communication connection is established with an external terminal device via the first SIM, the first SIM can occupy the RF resources of the multi-SIM wireless communication device. Therefore, when a request for a new wireless communication connection via the second SIM is received while wireless communication is being established via the first SIM, the multi-SIM wireless communication device terminates the existing wireless communication or rejects the new wireless communication connection.

The method includes: performing a first wireless communication with a first terminal device via the first SIM; receiving a request to connect to a second wireless communication from a second terminal device via the second SIM; determining a target SIM among the first SIM and the second SIM in response to the request; and performing the first wireless communication and the second wireless communication via the target SIM.

[0009] According to an aspect of the present inventive concept, there is provided a wireless communication apparatus including a first subscriber identity module (SIM), a second SIM, and a processing circuitry configured to determine a target SIM among the first SIM and the second SIM for a plurality of calls in response to receiving a request for a second call from a second terminal apparatus through the second SIM while a first call is being performed with a first terminal apparatus through the first SIM.

[0026] Figure 1 is a block diagram illustrating a wireless communication system according to an embodiment of the inventive concept. Referring to Figure 1 , the wireless communication system 10 can include a wireless communication device 100 and a plurality of networks (e.g., a first network 210 and a second network 220).

[0027] The wireless communication device 100 can refer to any device that is fixed or mobile and capable of transmitting and receiving data and / or control information through wireless communication with the networks 210 and 220. For example, the wireless communication device 100 can be referred to as a terminal, a terminal apparatus, a terminal device, a mobile station (MS), a mobile terminal (MT), a user terminal (UT), a subscriber station (SS), a wireless device, a handheld device, etc.

[0028] The first network 210 and the second network 220 can each include a base station (e.g., the first base station 211 or the second base station 221) and / or a first terminal device 213 or a second terminal device 223 connected to the first base station 211 or the second base station 221, respectively. The first base station 221 or the second base station 222 can refer to a fixed station that communicates with the wireless communication device 100, the first terminal device 213 or the second terminal device 223, and / or another base station. The first base station 221 or the second base station 222 can exchange data and / or control information with the wireless communication device 100, the first terminal device 213 or the second terminal device 223, and / or another base station by communication. For example, a base station can be referred to as a Node B, an evolved Node B (eNB), a next Generation Node B (gNB), a sector, a site, a base transceiver system (BTS), an access point (AP), a relay node, a remote radio head (RRH), a radio unit (RU), a small cell, etc. In the present specification, a base station can be understood as an integrated (non-limiting) term indicating a portion or a function covered by a base station controller (BSC) in a code division multiple access (CDMA) system, a Node B in a wideband CDMA (WCDMA) system, an eNB in a long term evolution (LTE) system, a gNB in a 5th generation new radio (5G NR) system, a sector (site), a relay node, an RRH, and / or an RU, and / or can include various coverage areas like a macro cell, a macro cell, a micro cell, a pico cell, a femto cell, and / or a small cell communication range.

[0029] The wireless communication device 100 can access the first network 210 through the first base station 211 and can access the second network 220 through the second base station 221. The wireless communication device 100 can communicate with the first network 210 and the second network 220 according to any radio access technology (RAT). For example, the wireless communication device 100 can communicate with the first network 210 and the second network 220 according to a 5th generation (5G) system, a 5G new radio (NR) system, a long term evolution (LTE) system, a code division multiple access (CDMA) system, a global system for mobile communications (GSM) system, a wireless local area network (WLAN) system, and / or another arbitrary RAT, but the present inventive concept is not limited thereto. The wireless communication device 100 can communicate with the first network 210 and the second network 220 according to the same RAT or a similar RAT in an embodiment, and can also communicate with the first network 210 and the second network 220 according to different RATs in an embodiment.

[0030] As Figure 1As illustrated, the wireless communication device 100 can include an antenna array 110, a radio frequency integrated circuit (RFIC) 120, a multi-SIM device 130, and / or m SIMs (e.g., a first SIM 141, a second SIM 142, a third SIM 143, etc. (m is an integer greater than 1)). The antenna array 110 can include at least one antenna and can receive RF signals from and / or transmit RF signals to the first base station 211 and the second base station 221. In an embodiment, the antenna array 110 can include multiple antennas used when performing multiple-input multiple-output (MIMO).

[0031] The RFIC 120 is hardware coupled with the antenna array 110 and the multi-SIM device 130, and can provide an RF resource (e.g., an RF path) for wireless communication. For example, the RFIC 120 can be referred to as a transceiver, can provide a reception signal RX as a baseband signal to the multi-SIM device 130 by processing an RF signal received from the antenna array 110, and can provide an RF signal to the antenna array 110 by processing a transmission signal TX as a baseband signal. The RFIC 120 can be controlled by the multi-SIM device 130, and as a non-limiting example, can include a switch, a matching circuit, a filter, an amplifier, a mixer, etc.

[0032] The multi-SIM device 130 can communicate with the RFIC 120 through baseband signals RX and TX, and can be coupled with the m SIMs (i.e., the first SIM 141, the second SIM 142, the third SIM 143, etc.). For example, the first SIM 141 can include information for accessing the first network 210 through the first wireless communication 11, and the second SIM 142 can include information for accessing the second network 220 through the second wireless communication 12. As described below with reference to FIGS. 2 and 3, the multi-SIM device 130 can have an architecture for processing a connection related to the first SIM 141 and a connection related to the second SIM 142. In an embodiment, the multi-SIM device 130 can include a hardware block designed through logic synthesis, a software block including a series of instructions, a processing unit including at least one processor for executing a series of instructions, and / or a combination thereof. In an embodiment, the multi-SIM device 130 can be referred to as a modem or a baseband processor. Figure 2 As described below, the multi-SIM device 130 can have an architecture for processing a connection related to the first SIM 141 and a connection related to the second SIM 142. In an embodiment, the multi-SIM device 130 can include a hardware block designed through logic synthesis, a software block including a series of instructions, a processing unit including at least one processor for executing a series of instructions, and / or a combination thereof. In an embodiment, the multi-SIM device 130 can be referred to as a modem or a baseband processor.

[0033] The m SIMs (i.e., the first SIM 141, the second SIM 142, the third SIM 143, etc.) can support multi-SIM (MS) wireless communication. For example, with reference to Figure 1In the case where the wireless communication device 100 is a DSDA device, the first SIM 141 and the second SIM 142 can share the RF resources (e.g., RF paths) provided by the RFIC 120. Accordingly, the first SIM 141 and the second SIM 142 can use the RFIC 120 in an exclusive manner to perform communication, and thus one of the connection with the first wireless communication 11 and the connection with the second wireless communication 12 can be suspended.

[0034] As in the above example, in the case where two wireless communications associated with two SIMs (i.e., the first SIM 141 and the second SIM 142) are performed, the wireless communication device 100 can be referred to as a dual-SIM device, and can operate as a dual receive single transmit dual-SIM dual-standby (DR-DSDS) device or a dual-SIM dual-active (DSDA) device.

[0035] When the wireless communication device 100 is a DR-DSDS device, the two SIMs (i.e., the first SIM 141 and the second SIM 142) can share the RF resources (e.g., RF paths) provided by the RFIC 120. Accordingly, the two SIMs (i.e., the first SIM 141 and the second SIM 142) can use the RFIC 120 in an exclusive manner to perform communication, and thus one of the connection with the first wireless communication 11 and / or the connection with the second wireless communication 12 can be suspended.

[0036] For example, the first SIM 141 can receive a request for a mobile termination (MT) call from the first terminal device 213 through the first base station 211, and perform a first call in response to the MT call request. At this time, the first SIM 141 can occupy the RFIC 120 to perform the first call, and the second wireless communication 12 through the second SIM 142 can be suspended. Also, the second SIM 142 can receive a request for a new second call from the second terminal device 223 through the second base station 221, and when a user of the wireless communication device 100 accepts the request for the second call, the second SIM 142 can occupy the RFIC 120 instead of the first SIM 141. Accordingly, the second call between the second SIM 142 and the second terminal device 223 is in a call active state, and the first call between the first SIM 141 and the first terminal device 213 can become a call hold state.

[0037] Generally, when the first call becomes a call hold state, the call dropped that ends communication is not immediately or simultaneously caused. However, because the first SIM 141 cannot occupy the RFIC 120 due to the second SIM 142, the first SIM 141 cannot transmit and / or receive a signal to and / or from the first base station 211. In addition, when there is no transmission and / or reception of a signal to and / or from the first SIM 141 for a predetermined (or alternatively, given) period of time, the first base station 211 can abandon the first call. Accordingly, the wireless communication device 100 according to the previous scheme is only able to temporarily maintain the first wireless communication 11 through the first SIM 141 and the second wireless communication 12 through the second SIM 142, and is not able to continuously maintain the first wireless communication 11 and the second wireless communication 12. In other words, the wireless communication device 100 according to the previous scheme can receive a request for a second call from the second SIM 142 while performing a first call through the first SIM 141, but it is difficult to continuously maintain one of the first call and the second call in a call hold state.

[0038] In addition, even when the wireless communication device 100 is a DR-DSDS device, the wireless communication device 100 according to an embodiment of the inventive concept can continuously perform the first wireless communication 11 and the second wireless communication 12 without pausing. In detail, when a connection of the first wireless communication 11 with the first SIM 141 and a connection of the second wireless communication 12 with the second SIM 142 are established, the multi-SIM device 130 can control either one of the first SIM 141 and the second SIM 142 to perform the first wireless communication 11 and the second wireless communication 12 based on information about the first wireless communication 11 or the second wireless communication 12. Hereinafter, the operation of the wireless communication device 100 will be described in detail.

[0039] First, the multi-SIM device 130 can perform the first wireless communication 11 with the first terminal device 213 through the first SIM 141. Next, while performing the first wireless communication 11, the multi-SIM device 130 can receive a connection request for the second wireless communication 12 between the second SIM 142 and the second terminal device 223 from the second base station 221. Next, a user of the wireless communication device 100 can accept the second wireless communication 12 with respect to the connection request for the second wireless communication 12 received by the multi-SIM device 130. In response to the acceptance signal, the multi-SIM device 130 can control the second SIM 142 to occupy the RFIC 120, and perform the second wireless communication 12 with the second terminal device 223. Accordingly, the first wireless communication 11 between the first SIM 141 and the first terminal device 213 can be switched to a call hold state, and the second wireless communication 12 between the second SIM 142 and the second terminal device 223 can be switched to a call active state.

[0040] Next, the multi-SIM device 130 can determine a target SIM for the first wireless communication 11 and / or the second wireless communication 12 among the first SIM 141 and the second SIM 142. The determined target SIM can occupy the RFIC 120. Next, the multi-SIM device 130 can identify a target terminal device among the first terminal device 213 and the second terminal device 223 for which the target SIM is not currently performing communication. Next, the multi-SIM device 130 can control the target SIM to transmit a wireless communication request to the target terminal device. Next, when an acceptance signal is received from the target terminal device, the multi-SIM device 130 can perform a wireless communication connection with the target terminal device through the target SIM. In addition, the multi-SIM device 130 can control the remaining SIMs other than the target SIM among the first SIM 141 and the second SIM 142 to end the wireless communication performed through the remaining SIMs.

[0041] For example, when the target SIM is the first SIM 141, the multi-SIM device 130 can control the first SIM 141 to transmit a request for connection of wireless communication to the second terminal device 223 that is not currently communicating with the first SIM 141. Next, when an acceptance signal is received from the second terminal device 223, the multi-SIM device 130 can perform a connection of a new second wireless communication 12 with the second terminal device 223 through the first SIM 141. Next, the multi-SIM device 130 can end the existing second wireless communication 12 between the second SIM 142 and the second terminal device 223. Accordingly, the multi-SIM device 130 can perform the existing connection of the first wireless communication 11 with the first terminal device 213 and the new connection of the second wireless communication 12 with the second terminal device 223 through the first SIM 141.

[0042] On the other hand, when a rejection signal is received from the second terminal device 223, the multi-SIM device 130 can determine that the second terminal device 223 does not want to communicate with the wireless communication device 100, and thus the multi-SIM device 130 can end the wireless communication connection with the second terminal device 223. In other words, the multi-SIM device 130 can end the existing second wireless communication 12 with the second terminal device 223 through the second SIM 142, and can not perform the new second wireless communication 12 with the second terminal device 223 through the first SIM 141.

[0043] In another example, when the target SIM is the second SIM 142, the multi-SIM device 130 can control the second SIM 142 to transmit a request for connection of a wireless communication to the first terminal device 213 that is not currently in communication with the second SIM 142. Next, when an acceptance signal is received from the first terminal device 213, the multi-SIM device 130 can perform connection of a new first wireless communication 11 with the first terminal device 213 through the second SIM 142. Next, the multi-SIM device 130 can end the existing first wireless communication 11 between the first SIM 141 and the first terminal device 213. Accordingly, the multi-SIM device 130 can perform the new existing first wireless communication 11 with the first terminal device 213 and the existing second wireless communication 12 with the second terminal device 223 through the second SIM 142.

[0044] In addition, when a rejection signal is received from the first terminal device 213, the multi-SIM device 130 can end the wireless communication with the first terminal device 213. In other words, the multi-SIM device 130 can end the existing first wireless communication 11 with the first terminal device 213 through the first SIM 141, and can not perform the new first wireless communication 11 with the first terminal device 213 through the second SIM 142.

[0045] In addition, even when the target SIM occupies the RFIC 120, both the first wireless communication 11 and the second wireless communication 12 do not have an active state, and at least one wireless communication can be in a hold state. For example, while the first wireless communication 11 is being performed, a request for connection of the second wireless communication 12 can be received, and a user can accept the request for connection of the second wireless communication 12. In this case, since the user prioritizes the second wireless communication 12 over the first wireless communication 11, the second wireless communication 12 can be in an active state and the first wireless communication 11 can be in a hold state.

[0046] At this time, unlike the previous method described above, even when the wireless communication is in a hold state, the wireless communication performed through the target SIM can be maintained without being ended. In detail, since the target SIM of the wireless communication device 100 is occupying the RFIC 120, a signal can be periodically or aperiodically transmitted to and received from a base station related to the wireless communication in the hold state. Accordingly, even when in the hold state, the wireless communication performed through the target SIM can be maintained without being ended.

[0047] As described above, when a plurality of wireless communications related to a plurality of SIMs, respectively, are established, the wireless communication device 100 according to an embodiment of the present inventive concept can maintain the wireless communications and improve user convenience by newly establishing at least one wireless communication through a target SIM, thereby maintaining the wireless communications and improving user convenience. Also, hereinafter, for convenience of explanation, a series of operations of connecting by newly establishing at least one wireless communication through a target SIM and ending wireless communications of remaining SIMs except for the target SIM will be referred to as a connection transfer operation.

[0048] Also, the wireless communication device 100 according to an embodiment of the present inventive concept is described above as a DR-DSDS device, but the present inventive concept can be applied in the same aspects when the wireless communication device 100 is a DSDA device. In other words, even when the RFIC 120 of the wireless communication device 100 provides RF resources independent of each other for two SIMs, i.e., the first SIM 141 and the second SIM 142, and the first SIM 141 and the second SIM 142 of the wireless communication device 100 are capable of performing reception independently of each other, the present inventive concept can be applied in the same aspects.

[0049] Also, embodiments of the present inventive concept will be described mainly with reference to wireless communication using two SIMs, i.e., the first SIM 141 and the second SIM 142 (e.g., dual-SIM wireless communication), but embodiments of the present inventive concept can be applied in the same aspects to multi-SIM wireless communication using three or more SIMs.

[0050] Also, although Figure 1 The wireless communication device 100 is shown to include the antenna array 110, the RFIC 120, the multi-SIM device 130, and m SIMs, i.e., the first SIM 141, the second SIM 142, and the third SIM 143, and descriptions thereof have been given above, but the wireless communication device 100 can further include an input device (not shown) for receiving a user input, a display (not shown) for displaying information to a user, etc.

[0051] Figure 2 is a block diagram illustrating a protocol stack system according to an embodiment of the present inventive concept. In detail, Figure 2 The control plane of the first protocol stack 21 and the second protocol stack 22 included in the protocol stack system 20 is shown. In an embodiment, Figure 2 The protocol stack system 20 of can be implemented in Figure 1 The multi-SIM device 130 of can perform wireless communication operations through the protocol stack system 20. Figure 2 At least some of the blocks shown can be implemented in hardware logic in an embodiment or in a software module executed by at least one processor in an embodiment.

[0052] Referring toFigure 1 and Figure 2 The protocol stack system 20 may include a first protocol stack 21 and a second protocol stack 22, respectively associated with the first SIM 141 and the second SIM 142. Each of the first protocol stack 21 and the second protocol stack 22 may support any RAT. In an embodiment, the first protocol stack 21 and the second protocol stack 22 may interact with a shared upper layer (e.g., an application layer), and the upper layer may provide the interface with programs for obtaining information about the first wireless communication 11 and the second wireless communication 12, or providing commands related to them. The upper layer may be implemented in the multi-SIM device 130, or it may be implemented in another device separate from the multi-SIM device 130.

[0053] Protocol stack system 20 may include a hardware interface 24 shared by the first protocol stack 21 and the second protocol stack 22. Hardware interface 24 can provide communication with hardware (e.g., ...). Figure 1 The hardware interface 24 provides an interface to the RFIC 120, and the first protocol stack 21 and the second protocol stack 22 can provide signals to or receive signals from the RFIC 120 through the hardware interface 24. In an embodiment, the hardware interface 24 may be referred to as the driver of the RFIC 120.

[0054] The first protocol stack 21 and the second protocol stack 22 used for the control plane can each include multiple layers. For example... Figure 2 As shown, the first protocol stack 21 may include a first layer L1, a second layer L2, and a third layer L3, and the first layer L1, the second layer L2, and the third layer L3 may correspond to the lower three layers of the Open Systems Interconnection (OSI) model. For example, in LTE or 5G NR, the Physical (PHY) layer may be included in the first layer L1, the Medium Access Control (MAC) layer, the Radio Link Control (RLC) layer, and the Packet Data Convergence Protocol (PDCP) layer may be included in the second layer L2, and the Radio Resource Control (RRC) layer and the Non-Access Plane (NAS) layer may be included in the third layer L3. Similar to the first protocol stack 21, the second protocol stack 22 may also include the first layer L1, the second layer L2, and the third layer L3. In this specification, the operations performed by the first protocol stack 21 may be referred to as operations performed by the first SIM 141, and the operations performed by the second protocol stack 22 may be referred to as operations performed by the second SIM 142.

[0055] According to an embodiment of the present inventive concept, the first protocol stack 21 and the second protocol stack 22 can share information about wireless communication with each other. For example, the first protocol stack 21 can perform the first wireless communication 11 with the first terminal device 213, and the second protocol stack 22 can perform the second wireless communication 12 with the second terminal device 223. Also, the multi-SIM device 130 can determine the first SIM 141 as a target SIM to perform a plurality of wireless communications. Also, the first protocol stack 21 can request information about the second wireless communication 12 from the second protocol stack 22. The second protocol stack 22 can share information about the second wireless communication with the first protocol stack 21 in response to the request.

[0056] Here, the information about the wireless communication can include information about a terminal device accessing the wireless communication and / or information about a SIM accessing the wireless communication. The information about the terminal device accessing the wireless communication can include at least one of a device identifier (ID), an IP address, and / or a serial code. Also, the information about the terminal device is not limited to the above-described example, and can include various other information.

[0057] Also, the information about the SIM accessing the wireless communication, which can be referred to as SIM information or user information, hereinafter referred to as SIM information for convenience of explanation, can include at least one of a call editor ID and a session initiation protocol (SIP) call ID of a call that has been previously performed or is currently being performed by the corresponding SIM. The first protocol stack 21 can transmit a request for connection of a new wireless communication by using the received SIM information. In detail, the first protocol stack 21 can include the received SIM information in information for connection in a rich call function supported by a rich communication service (RCS) generic configuration file 2.0 or a higher version thereof, and transmit a request for connection of the wireless communication. Here, the rich call function can refer to a function of sharing user information content before, during, and / or after a voice call. Also, for example, items defined in the rich call function can include an important call indicator, a subject, an image, a location, and can set these items for each SIM requesting connection of the wireless communication. Definitions of the above-described items are as follows.

[0058] [Table 1]

[0059]

[0060] (* A party: a party that initiates a communication event (e.g., creates and transmits a chat message or a file transfer, or initiates a call to the B party).

[0061] * B party: a party that receives or intends to receive a communication event (e.g., a chat message, a file transfer, or a call from the A party).

[0062] Further, the SIM information and the information for connection in the enhanced call function are not limited to the above-stated examples, and can include various other information.

[0063] In addition, the first protocol stack 21 can transmit a request for connection of a new second wireless communication to the second terminal device 223 based on the information about the second terminal device 223. The request for connection of the new second wireless communication can include information about the second SIM 142. In addition, the second terminal device 223 can use the information about the second SIM 142 included in the request for connection of the new second wireless communication to determine whether the first SIM 141 and the second SIM 142 are both included in the wireless communication device 100.

[0064] In detail, when the connection of the new second wireless communication is requested, the second terminal device 223 can determine whether the user information of the peer SIM that has communicated with the second terminal device 223 is the same as or similar to the user information of the second SIM 142 by using the information about the second SIM 142 included in the received request. When the user information of the two SIMs is the same or similar, the second terminal device 223 can determine that the wireless communication request is received from another SIM (e.g., the first SIM 141) of the wireless communication device 100 that includes the SIM (i.e., the second SIM 142) that has communicated with the second terminal device 223. In other words, although the first SIM 141 and the second SIM 142 are different SIMs from each other, since the first SIM 141 and the second SIM 142 are both included in the same wireless communication device 100 or a similar wireless device and used by the same user or a similar user, the second terminal device 223 can accept the request for the second wireless communication 12 of the first SIM 141.

[0065] In addition, when the first protocol stack 21 receives the acceptance signal from the second terminal device 223, the first protocol stack 21 can perform the new second wireless communication 12 with the second terminal device 223. Further, although the above describes that the second protocol stack 22 provides the information about the wireless communication to the first protocol stack 21, the first protocol stack 21 can also provide the information about the wireless communication to the second protocol stack 22. In addition, although the above examples show and describe that the first protocol stack 21 and the second protocol stack 22 share the information by the request for the information about the wireless communication and the response thereto, in an embodiment, the information can be shared by storing the information about the wireless communication in a memory that can be commonly accessed by the first protocol stack 21 and the second protocol stack 22.

[0066] The resource manager 23 can manage resources of the RFIC 120 to be provided to the wireless communication of the first protocol stack 21 and the wireless communication of the second protocol stack 22. For example, when the wireless communication apparatus 100 is a DR-DSDS apparatus and establishes the wireless communication through the first SIM 141, the resource manager 23 can allocate resources of the RFIC 120 to the wireless communication of the first protocol stack 21. The resource manager 23 can be stored in the memory as a software module executed by at least one processor in an embodiment, or can be a hardware module designed through logic synthesis in an embodiment.

[0067] Figure 3 is a flowchart of a wireless communication method according to an embodiment of the inventive concept. In detail, Figure 3 is a flowchart illustrating an example of a wireless communication method of the wireless communication apparatus 100. The wireless communication method can be performed at least in part by the multi-SIM apparatus 130. Figure 1 Figure 1 Referring to and

[0068] , the wireless communication apparatus 100 can perform the first wireless communication 11 with the first terminal apparatus 213 through the first SIM 141 (operation S110). In detail, when the wireless communication apparatus 100 receives a request (e.g., a first call request) for connection of the first wireless communication 11 from the first terminal apparatus 213 through the first SIM 141, the wireless communication apparatus 100 can perform the first wireless communication 11 with the first terminal apparatus 213 through the first SIM 141 in response to the received request. Alternatively, the wireless communication apparatus 100 can transmit a request for the first wireless communication 11 to the first terminal apparatus 213 through the first SIM 141, and in response to an acceptance signal of the first terminal apparatus 213, can perform the first wireless communication 11 with the first terminal apparatus 213 through the first SIM 141. Figure 1 Figure 3 Next, the wireless communication apparatus 100 can receive a request (e.g., a second call request) for connection of the second wireless communication 12 from the second terminal apparatus 223 through the second SIM 142 (operation S120). Next, the wireless communication apparatus 100 can determine a target SIM for the first wireless communication 11 and the second wireless communication 12 among the first SIM 141 and the second SIM 142 in response to the request (operation S130).

[0069] Next, the wireless communication apparatus 100 can receive a request (e.g., a second call request) for connection of the second wireless communication 12 from the second terminal apparatus 223 through the second SIM 142 (operation S120). Next, the wireless communication apparatus 100 can determine a target SIM for the first wireless communication 11 and the second wireless communication 12 among the first SIM 141 and the second SIM 142 in response to the request (operation S130).

[0070] ​In detail, in response to the request, the wireless communication device 100 can inform a user of the wireless communication device 100 that a request for connection of the second wireless communication 12 has been received from the second terminal device 223. When the user accepts the second wireless communication 12, the wireless communication device 100 can determine the target SIM to maintain connection of the two wireless communications as described in the inventive concept. On the other hand, when the user rejects the second wireless communication 12, the operation of determining the target SIM can be omitted, and only the first wireless communication 11 can be performed. In addition, the following will be described with reference to Figure 4 The operation in which the wireless communication device 100 determines the target SIM is described in detail.

[0071] Next, the wireless communication device 100 can perform the first wireless communication 11 and the second wireless communication 12 through the target SIM (operation S140). In detail, the wireless communication device 100 can obtain information for confirming that the first SIM 141 and the second SIM 142 are included in the same peer wireless communication device or a similar peer wireless communication device. For example, the wireless communication device 100 can obtain a call editor ID and / or a SIP call ID of a previous or existing connection of the remaining SIMs other than the target SIM among the first SIM 141 and the second SIM 142. Next, the wireless communication device 100 can include the obtained information in information on pre-call services (for example, an important call indicator, a subject, an image, or location information) among rich call functions set for the target SIM.

[0072] Next, the wireless communication device 100 can identify a target terminal device among the first terminal device 213 and the second terminal device 223 for which the target SIM is not currently performing communication. Next, the wireless communication device 100 can transmit a connection request (for example, a third call request) of the wireless communication to the target terminal device through the target SIM along with the obtained information. For example, the wireless communication device 100 can transmit the connection request of the wireless communication by transmitting information on pre-call services of the target SIM including the obtained information on the remaining SIMs to the target terminal device.

[0073] When an acceptance signal is received from the target terminal device, the wireless communication device 100 can perform the wireless communication with the target terminal device through the target SIM. On the other hand, when a rejection signal is received from the target terminal device, the wireless communication device 100 can determine that the target terminal device does not want to communicate with the wireless communication device 100, and thus the wireless communication device 100 can end the wireless communication (for example, the first call or the second call) with the target terminal device.

[0074] Figure 4 is a diagram for describing a method through which a wireless communication device determines a target SIM according to an embodiment of the inventive concept. In detail,Figure 4 is for describing Figure 3 a detailed operation of operation S130. In an embodiment, the wireless communication device 100 can receive selection of a target SIM from a user.

[0075] Referring to Figure 1 , Figure 3 and Figure 4 , while performing the first call with Dennis through the first SIM 141 (SIM 1), the wireless communication device 100 can receive a request for a second call from Janet through the second SIM 142 (SIM 2). Next, the wireless communication device 100 can receive an acceptance signal for the second call from the user. In this case, the wireless communication device 100 can display a user interface (UI) requesting the user to select a target SIM to be used for multiple wireless communications, through the display, in order to maintain two communications with Dennis and Janet.

[0076] In detail, the wireless communication device 100 can display a first option (SIM 1 to SIM 2) for transferring wireless communication of the first SIM 141 to the second SIM 142, a second option (SIM 2 to SIM 1) for transferring wireless communication of the second SIM 142 to the first SIM 141, and / or a third option (SIM 1 end & SIM 2 accept) for ending wireless communication of the first SIM 141 and performing only wireless communication of the second SIM 142, and receive selection of one option from the user.

[0077] Next, the wireless communication device 100 can determine a target SIM according to the selected option. For example, when the first option (SIM 1 to SIM 2) is selected, the wireless communication device 100 can determine the second SIM 142 as the target SIM. Next, the wireless communication device 100 can transmit a request for a third call to Dennis through the second SIM 142 by using information about the first call between the first SIM 141 and Dennis. Next, when Dennis accepts the request for the third call, the wireless communication device 100 can perform the third call with Dennis through the second SIM 142 and end the first call between the first SIM 141 and Dennis.

[0078] In addition, when the second option (SIM 2 to SIM 1) is selected, the wireless communication device 100 can determine the first SIM 141 as the target SIM. Next, the wireless communication device 100 can transmit a request for a third call to Janet through the first SIM 141 by using information about the second call between the second SIM 142 and Janet. Next, when Janet accepts the request for the third call, the wireless communication device 100 can perform the third call with Janet through the first SIM 141 and end the second call between the second SIM 142 and Janet.

[0079] In addition, when the third option (SIM 1 end & SIM 2 accept) is selected, the wireless communication device 100 determines that the user does not want to perform multiple wireless communications through a single SIM, and can end the wireless communication of the first SIM 141 (e.g., the first call with Dennis) without determining the target SIM.

[0080] Further, the method through which the wireless communication device 100 determines the target SIM is not limited to the examples stated above. For example, the wireless communication device 100 can check a preset (or alternatively, given) SIM for multiple wireless communications, and can determine the checked SIM as (e.g., is) the target SIM.

[0081] Figure 5 is a flowchart of a method of performing multiple wireless communications of a target SIM according to an embodiment of the inventive concept. In detail, Figure 5 is a flowchart illustrating Figure 3 a detailed example of operation S130 and operation S140. Hereinafter, an embodiment in which the first SIM 141 is determined as the target SIM will be described.

[0082] Referring to Figure 1 , Figure 3 and Figure 5 , the wireless communication device 100 can first determine the first SIM 141 as the target SIM (operation S210). For example, referring to Figure 4 , when the user selects the second option (SIM 2 to SIM 1), the wireless communication device 100 can determine the first SIM 141 as the target SIM. Next, the wireless communication device 100 can obtain information about the second wireless communication 12 (operation S220). In detail, the first protocol stack 21 of the wireless communication device 100 can obtain information about a connection of the second wireless communication 12 from the second protocol stack 22. The information about the connection of the second wireless communication 12 can include information about the second terminal device 223 and / or information about the second SIM 142.

[0083] Next, the wireless communication device 100 can transmit a connection request for wireless communication to the second terminal device 223 through the first SIM 141 (operation S230). In detail, the wireless communication device 100 can transmit the connection request for wireless communication to the second terminal device 223 through the first SIM 141 along with information about the second SIM 142.

[0084] Next, the wireless communication device 100 can determine whether an acceptance signal of the second terminal device 223 is received (operation S240). When the acceptance signal is not received from the second terminal device 223 (operation S240 - No), the wireless communication device 100 can determine that the second terminal device 223 does not want to communicate with the wireless communication device 100. Accordingly, the wireless communication device 100 can not perform wireless communication with the second terminal device 223 through the first SIM 141, and also end the previously established second wireless communication 12 with the second terminal device 223 through the second SIM 142 (operation S260).

[0085] On the other hand, when the acceptance signal is received from the second terminal device 223 (operation S240 - Yes), the wireless communication device 100 can perform connection of a new second wireless communication 12 with the second terminal device 223 through the first SIM 141 (operation S250). In other words, the wireless communication device 100 can perform the previously established first wireless communication 11 and the newly established second wireless communication 12 through the first SIM 141. Also, since the user of the wireless communication device 100 has approved connection of the requested second wireless communication 12 while performing the first wireless communication 11 in the previous operation, the second wireless communication 12 can be in an active state, and the first wireless communication 11 can be in a hold state.

[0086] Next, the wireless communication device 100 can end the previously established second wireless communication 12 with the second terminal device 223 through the second SIM 142 to prevent or reduce communication duplication (operation S260).

[0087] Figure 6 is a flowchart of a method of performing a plurality of wireless communications of a target SIM according to an embodiment of the inventive concept. In detail, Figure 6 is a flowchart illustrating a detailed example of operations S130 and S140 of Figure 3 Hereinafter, an embodiment in which the second SIM 142 is determined as the target SIM will be described.

[0088] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 6 , the wireless communication device 100 can first determine the second SIM 142 as the target SIM (operation S310). For example, referring toFigure 4 When the user selects the first option (SIM 1 to SIM 2), the wireless communication device 100 can determine the second SIM 142 as a target SIM. Next, the wireless communication device 100 can obtain information about the first wireless communication 11 (operation S320). In detail, the second protocol stack 22 of the wireless communication device 100 can obtain information about the connection of the first wireless communication 11 from the first protocol stack 21. The information about the connection of the first wireless communication 11 can include information about the first terminal device 213 and / or information about the first SIM 141.

[0089] Next, the wireless communication device 100 can transmit a connection request for wireless communication to the first terminal device 213 through the second SIM 142 (operation S330). In detail, the wireless communication device 100 can transmit the connection request for wireless communication to the first terminal device 213 through the second SIM 142 along with information about the first SIM 141.

[0090] Next, the wireless communication device 100 can determine whether an acceptance signal of the first terminal device 213 is received (operation S340). When the acceptance signal is not received from the first terminal device 213 (operation S340-NO), the wireless communication device 100 can determine that the first terminal device 213 does not want to communicate with the wireless communication device 100. Accordingly, the wireless communication device 100 can not perform wireless communication with the first terminal device 213 through the second SIM 142, and also end the previously established first wireless communication 11 with the first terminal device 213 through the first SIM 141 (operation S360).

[0091] On the other hand, when the acceptance signal is received from the first terminal device 213 (operation S340-YES), the wireless communication device 100 can perform connection of a new first wireless communication 11 with the first terminal device 213 through the second SIM 142 (operation S350). In other words, the wireless communication device 100 can perform a newly established first wireless communication 11 and a previously established second wireless communication 12 through the second SIM 142. Further, since the user of the wireless communication device 100 has approved connection of the requested first wireless communication 11 while the second wireless communication 12 is being performed in the previous operation, the first wireless communication 11 can have an active state, and the second wireless communication 12 can be in a hold state.

[0092] Next, the wireless communication device 100 can end the previously established first wireless communication 11 with the first terminal device 213 through the first SIM 141 to prevent or reduce communication duplication (operation S360).

[0093] Figure 7is a flowchart of a method of ending wireless communication by a wireless communication device according to an embodiment of the inventive concept. In detail, Figure 7 is a flowchart illustrating an example of detailed operations of operation S 130 and operation S 140 of Figure 3 . Hereinafter, an embodiment in which the first SIM 141 and the second SIM 142 are not both determined as target SIMs will be described.

[0094] Referring to Figure 1 , Figure 3 and Figure 7 , the wireless communication device 100 can receive an end signal of the first wireless communication 11 (operation S410). For example, referring to Figure 4 , when the user selects the third option (SIM 1 end & SIM 2 accept), the wireless communication device 100 can not determine a target SIM.

[0095] Next, the wireless communication device 100 can end the first wireless communication 11 with the first terminal device 213 through the first SIM 141 (operation S420). Next, the wireless communication device 100 can perform only the second wireless communication 12 with the second terminal device 223 through the second SIM 142.

[0096] Figure 8 is a flowchart of a method of transferring wireless communication of a terminal device according to an embodiment of the inventive concept. In detail, Figure 8 is a flowchart for describing a method of transferring wireless communication from the perspective of a terminal device performing communication with any one SIM of the wireless communication device 100. In the present example, it is assumed that the terminal device is a device supporting an enhanced call function. In addition, for convenience of explanation, a description will be given below based on the operation of the first terminal device 213 of Figure 1 , but the second terminal device 223 of Figure 1 may operate in substantially the same manner.

[0097] Referring to Figure 1 and Figure 8 , the first terminal device 213 can perform the first wireless communication 11 with the first SIM 141 of the wireless communication device 100 (operation S510). Next, the first terminal device 213 can receive a request for new wireless communication from the second SIM 142 of the wireless communication device 100 while performing the first wireless communication 11 (operation S520). In detail, the first terminal device 213 can receive the new wireless communication request including information about the first SIM 141 performing the existing wireless communication from the second SIM 142. The information about the first SIM 141 (e.g., a call editor ID and / or a SIP call ID) can be received by being included in information used in a pre-call service among enhanced call functions.

[0098] Next, the first terminal device 213 can determine whether the first SIM 141 and the second SIM 142 correspond to the same user (operation S525) or a similar user. In an embodiment, since the first terminal device 213 supports a rich call function, it can be determined whether the first SIM 141 and the second SIM 142 are both included in the wireless communication device 100 based on information about the first SIM 141. In detail, the first terminal device 213 can compare information about the SIM (e.g., the first SIM 141) that is currently communicating with the first terminal device 213 with information about the first SIM 141 included in the wireless communication request newly received from the second SIM 142, thereby determining whether the SIM (e.g., the first SIM 141) that is currently communicating with the first terminal device 213 is the same as or similar to the SIM (e.g., the second SIM 142) to which the information included in the received request corresponds. When the two SIMs are the same or similar, the first terminal device 213 can determine that the wireless communication request is received from another SIM (e.g., the second SIM 142) of the wireless communication device 100 that includes the SIM (e.g., the first SIM 141) that has been communicating with the first terminal device 213. In other words, the first terminal device 213 can determine that the first SIM 141 and the second SIM 142 correspond to the same user or a similar user.

[0099] When it is determined that the first SIM 141 and the second SIM 142 do not correspond to the same user or a similar user (operation S525 - No), the first SIM 141 and the second SIM 142 can be included in different wireless communication devices, and thus it can be determined that the wireless communication request is received from another user using the second SIM 142 while performing wireless communication with the user using the first SIM 141. Accordingly, the first terminal device 213 can receive a selection of whether the user of the first terminal device 213 accepts the wireless communication request from the second SIM 142 (operation S530). When the user of the first terminal device 213 accepts connection of the wireless communication connection from the second SIM 142 (operation S530 - Yes), the first wireless communication with the first SIM 141 can end (operation S535), and a new wireless communication can be performed with the second SIM 142 (operation S540). On the other hand, when the user of the first terminal device 213 does not accept the wireless communication connection from the second SIM 142 (operation S530 - No), a rejection signal can be transmitted to the second SIM (operation S545), and the first wireless communication with the first SIM 141 can be continued (e.g., maintained).

[0100] On the other hand, when it is determined that the first SIM 141 and the second SIM 142 correspond to the same user or a similar user (operation S525 - Yes), the first terminal device 213 can check whether an automatic communication transfer function is set (operation S550). Here, the automatic communication transfer function can refer to a function in which, when a terminal device supporting a rich call function receives a communication request (e.g., a rich call request) from another SIM while the terminal device performs communication with a specific SIM, it is determined whether the SIM (e.g., the second SIM 142) of the current communication and the other SIM (e.g., the first SIM 141) correspond to the same user or a similar user by using previous call information about a user (or a sender) included in the received rich call request, and when it is determined that the two SIMs correspond to the same user or a similar user, the communication request from the other SIM is automatically accepted. Furthermore, the name of the automatic communication transfer function is merely an example, and can be called various names.

[0101] When the automatic communication transfer function is set to the first terminal device 213 (operation S550 - Yes), the first terminal device 213 can perform a new wireless communication connection with the second SIM 142 (operation S560), and end the existing first wireless communication 11 with the first SIM 141 to prevent or reduce communication duplication (operation S565).

[0102] On the other hand, when the automatic communication transfer function is not set to the first terminal device 213 (operation S550 - No), the first terminal device 213 can receive a selection of whether to accept a wireless communication connection request from the second SIM 142 by a user of the first terminal device 213 (operation S555). At this time, the first terminal device 213 can display information about the second SIM 142 through a display, and receive a selection of whether to accept a wireless communication connection request from the second SIM 142. A detailed description of the operation in which the first terminal device 213 receives a selection of whether to accept a wireless communication connection request from the second SIM 142 will be given later with reference to FIG. 6. Figure 11 A detailed description of the operation in which the first terminal device 213 receives a selection of whether to accept a wireless communication connection request from the second SIM 142 will be given later with reference to FIG. 6.

[0103] When an acceptance signal of the wireless communication connection request from the second SIM 142 is received from the user (operation S555 - Yes), the first terminal device 213 can perform a new wireless communication connection with the second SIM 142 (operation S560), and end the existing first wireless communication 11 with the first SIM 141 to prevent or reduce communication duplication (operation S565). On the other hand, when an acceptance signal of the wireless communication connection request from the second SIM 142 is not received from the user (operation S555 - No), the first terminal device 213 can transmit a rejection signal to the second SIM 142, and the wireless communication apparatus 100 can determine that the first terminal device 213 does not accept the transfer of the wireless communication to the second SIM 142. Accordingly, the wireless communication apparatus 100 can transmit a request to end the first wireless communication 11 through the first SIM 141 to the first terminal device 213, and the first terminal device 213 can end the first wireless communication 11 with the first SIM 141 (operation S565).

[0104] On the other hand, although the description is given above with reference to Figure 8 The description is given on the assumption that the first terminal device 213 is a device supporting the rich call function, but the first terminal device 213 can be a device not supporting the rich call function. In this case, even when additional information about the first SIM 141 is received together with the new wireless communication request from the second SIM 142, the first terminal device 213 can not be able to determine whether the first SIM 141 and the second SIM 142 are both included in the wireless communication apparatus 100.

[0105] Accordingly, the first terminal device 213 can receive the selection of whether the user accepts the wireless communication request from the second SIM 142. When the user of the first terminal device 213 accepts, the existing wireless communication with the first SIM 141 can be ended, and a new wireless communication with the second SIM 142 can be performed. On the other hand, when the user of the first terminal device 213 rejects, the wireless communication with the second SIM 142 can be rejected. In an embodiment, when the first SIM 141 and the second SIM 142 are included in different wireless communication apparatuses and the user of the first terminal device 213 rejects the wireless communication request from the second SIM 142, the first terminal device 213 can maintain the wireless communication with the first SIM 141. In an embodiment, when the first SIM 141 and the second SIM 142 are included in the wireless communication apparatus 100 according to an embodiment of the inventive concept and the user of the first terminal device 213 rejects the wireless communication request from the second SIM 142, the wireless communication with the second SIM 142 is not performed, and thus the wireless communication with the first SIM 141 can also be ended.

[0106] Figure 9is a diagram for describing a method of selecting an automatic transfer setting of a wireless communication connection of a receiving terminal device according to an embodiment of the inventive concept. In detail, Figure 9 is a diagram for describing an example of an operation of receiving a selection of a setting of an automatic communication transfer function from Figure 8 a user of a first terminal device 213. Also, for convenience of explanation, a description will be given below based on Figure 1 an operation of the first terminal device 213, but Figure 1 a second terminal device 223 can operate in substantially the same manner.

[0107] Referring to Figure 1 , Figure 8 and Figure 9 , the first terminal device 213 can execute software called a rich call manager, and the first terminal device 213 can display a setting of a rich call function to a user through a display.

[0108] In detail, the first terminal device 213 can display a setting of an automatic communication transfer function as a rich call function. A user can select whether to turn on or off the automatic communication transfer function through an input device of the first terminal device 213 or a display supporting touch input. The selection of the user can be stored in a memory of the first terminal device 213.

[0109] Figure 10 is a diagram for describing a method by which a terminal device receives a selection of whether to transfer a wireless communication connection according to an embodiment of the inventive concept.

[0110] Figure 10 is a diagram for describing a method of receiving a selection of whether to transfer a wireless communication connection of a terminal device according to an embodiment of the inventive concept.

[0111] Referring to Figure 1 , Figure 8 and Figure 10 , while the wireless communication device 100 performs a first wireless communication with the first terminal device 21 through the first SIM 141, the wireless communication device 100 can establish a second wireless communication through the second SIM 142 according to a request of the second terminal device 223. Next, when the wireless communication device 100 determines the second SIM 142 as a target SIM, the wireless communication device 100 can transmit a new wireless communication connection request to the first terminal device 213 through the second SIM 142. Hereinafter, an operation of the first terminal device 213 in the above-described case will be described.

[0112] Referring to Figure 10While the first wireless communication (e.g., the first call) is being performed through the first SIM 141 corresponding to John 1, the first terminal device 213 can receive a request for a new second wireless communication (e.g., a second call) from the second SIM 142 corresponding to John 2. At this time, the request for the second wireless communication can include at least one of a call editor ID and / or a call ID of the previous call or the current call of the first SIM 141 as information about the first SIM 141 in items (i.e., items including an important call indicator, a subject, an image, and / or a location) of the rich call information about the second SIM 142. In addition, the rich call information about the second wireless communication call can include a message that is preset to request the user of the first terminal device 213 to accept the second wireless communication.

[0113] Then, the first terminal device 213 can display a message requesting acceptance of the second call, and receive a selection of whether to accept the second wireless communication request from the second SIM 142 from the user of the first terminal device 213. The user can select to accept or reject the second wireless communication request from the second SIM 142 through an input device of the first terminal device 213 or a display supporting touch input.

[0114] When the user selects to accept, the first terminal device 213 can perform the wireless communication with the second SIM 142 and end the wireless communication with the first SIM 141. On the other hand, when the user selects to reject, the first terminal device 213 can transmit a rejection signal to the second SIM 142, and end the wireless communication with the first SIM 141 according to the request of the first SIM 141.

[0115] Further, Figure 10 An example of the first terminal device 213 being set to turn off the automatic communication transfer function is an embodiment in which the first terminal device 213 is set to turn on the automatic communication transfer function and receives a connection request for a new second wireless communication from the second SIM 142 corresponding to John 2 while the first wireless communication is being performed through the first SIM 141 corresponding to John 1. In other words, the first terminal device 213 can determine whether the first SIM 141 and the second SIM 142 correspond to the same user or a similar user without receiving a selection of whether the user accepts the wireless communication with the second SIM 142, and when it is determined that the two SIMs correspond to the same user or a similar user, the first terminal device 213 can automatically perform the wireless communication with the second SIM 142.
