Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2018-0127689 filed on October 24, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to a multi-subscriber identity module (SIM) device and a method of operating the multi-SIM device. The multi-SIM device includes radio frequency (RF) resources allocated to SIMs and manages the allocation of RF resources. Background Art

[0004] Multi-SIM devices such as mobile phones, personal digital assistants (PDAs), tablet computers and laptop computers may include at least two SIM cards. Each SIM card may include a unique international mobile subscriber identity (IMSI) and key information that allows a user of the multi-SIM device to be identified and authenticated by a service provider. A multi-SIM device allows a user to access various networks by using the SIM cards.

[0005] When the multi-SIM device is a dual SIM dual standby (DSDS) device, multiple SIMs share one RF resource, and thus when the request intervals for the use of RF resources of the multiple SIMs overlap each other, the communication performance of the multi-SIM device is deteriorated due to the SIMs to which the RF resources are not allocated. In addition, when the multi-SIM device is a dual SIM dual active (DSDA) device, multiple RF resources are provided and the multiple RF resources are respectively allocated to the SIMs, and thus when the multi-SIM device is a DSDA device, the communication performance of the DSDA multi-SIM device is better. However, the hardware and software specifications are large, and thus the manufacturing cost of the DSDA multi-SIM device and the amount of power consumed by the DSDA multi-SIM device are greatly increased.

[0008] According to another aspect of the embodiment, a multi-SIM device is provided, comprising: a plurality of SIMs; a plurality of radio frequency (RF) resources allocated to the plurality of SIMs, wherein, according to a radio resource control (RRC) protocol, a first portion of the plurality of RF resources supports the use of a non-restricted channel configuration, and a second portion of the plurality of RF resources supports the use of a restricted channel configuration; and a baseband processor configured to control the plurality of RF resources to support the use of the non-restricted channel configuration for one of the at least two target SIMs and to support the use of the restricted channel configuration for the other of the at least two target SIMs in response to RF resource use request intervals of at least two target SIMs overlapping each other, based on information about networks respectively corresponding to the at least two target SIMs.

[0009] According to another aspect of the embodiment, there is provided an operating method of operating a multi-subscriber identity module (SIM) device including a first SIM and a second SIM, the operating method including: using the first SIM to generate a radio frequency (RF) resource request; based on first information about a first network corresponding to the first SIM and second information about a second network corresponding to the second SIM, determining whether a dual radio (DR) mode supporting both use of an unrestricted channel configuration and use of a restricted channel configuration can be set; and based on a result of the determination, selectively allocating first RF resources supporting use of the unrestricted channel configuration and second RF resources supporting use of the restricted channel configuration to the first SIM and the second SIM.

[0010] According to another aspect of the embodiment, a multi-subscriber identity module (SIM) device is provided, the multi-SIM device comprising: a first radio frequency (RF) resource configured to support the use of an unrestricted channel configuration according to a radio resource control (RRC) protocol; a second RF resource configured to support the use of a restricted channel configuration according to the RRC protocol; and a baseband processor configured to communicate with a first network and a second network based on information stored in a first SIM and a second SIM using the first RF resource and the second RF resource, wherein the baseband processor operates the multi-SIM device in a dual SIM dual standby (DSDS) mode except in response to a first RF resource usage interval of the first SIM overlapping a second RF resource usage interval of the second SIM.

[0030] Hereinafter, one or more embodiments will be described in detail with reference to the accompanying drawings.

[0031] Figure 1 1 is a block diagram of a wireless communication system. According to an embodiment, the wireless communication system 1 includes a multi-SIM device 100 and a first base station 10 and a second base station 20. As a non-limiting example, the wireless communication system 1 may be a fifth generation (5G) wireless communication system. thThe multi-SIM device 100 may be connected to a specific wireless communication network through the first base station 10 and the second base station 20, and may send information from the wireless communication network in the following access modes, for example: code division multiple access (CDMA), wideband code division multiple access (WCDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), OFDM-FDMA, OFDM-TDMA and OFDM-CDMA. In this case, the multi-SIM device 100 and the first base station 10 and the second base station 20 can communicate with each other, and can receive / transmit signals (or data) through various channels. In this specification, the reception / transmission of signals (or data) through channels may be described as reception / transmission of channels. In addition, for convenience, the communication between the baseband processor 110 and the first base station 10 and the second base station 20 using the first SIM 120_1 and the second SIM 120_2 may be described as the communication between the first SIM 120_1 and the second SIM 120_2 and the first base station 10 and the second base station 20. In other words, when such a description is used, it will be understood that the baseband processor 110 is communicating with the first base station 10 and the second base station 20.

[0032] Reference Figure 1, the multi-SIM device 100 may include a baseband processor 110, a first SIM 120_1, a second SIM 120_2, and a memory 130. The first SIM 120_1 will use the first network service and can connect to the first network through the first base station 10. The second SIM 120_2 will use the second network service and can connect to the second network through the second base station 20.

[0033] The baseband processor 110 may include a first radio frequency (RF) resource 112_1 and a second RF resource 112_2. The first RF resource 112_1 and the second RF resource 112_2 may include tangible or intangible resources for processing a circuit and path for receiving a channel from the first base station 10 and the second base station 20 or a transmission / reception channel. Hereinafter, the case of receiving a channel using the first RF resource 112_1 and the second RF resource 112_2 will be mainly described, but this is only an example. The embodiment is not limited thereto, and it will be understood that the first RF resource 112_1 and the second RF resource 112_2 may be used to transmit a channel.

[0034] In an embodiment, the first RF resource 112_1 may support the use of a non-limited channel configuration according to a radio resource control (RRC) protocol, and the second RF resource 112_2 may support the use of a limited channel configuration according to an RRC protocol. In detail, the first RF resource 112_1 may support processing of channels handled by a specific SIM to maintain a network connection mode and channels handled in an idle mode. The second RF resource 112_2 may only support processing of channels handled by a specific SIM in an idle mode. In addition, the channels handled by the SIM in the idle mode may have a periodic characteristic and may include scheduling information notifying the transmission timing of the channel. For example, when the wireless communication system 1 is a WCDMA system, the channels handled by the SIM to maintain a network connection mode may be a dedicated channel (Dedicated Channel, DCH), a forward access channel (Forward Access Channel, FACH), a random access channel (Random Access Channel, RACH), a broadcast channel (Broadcast Channel, BCH), a paging channel (Paging Channel, PCH), etc. The channels handled by the SIM in the idle mode may be defined as BCH and PCH. In addition, when the wireless communication system 1 is an LTE system, the channels handled by the SIM to maintain the network connection mode may be a downlink shared channel (DL-SCH), a multicast channel (MCH), BCH, PCH, etc., and the channels handled by the SIM in the idle mode may be a multicast channel (MCH), BCH, and PCH.

[0035] As described above, since the first RF resource 112_1 must support processing more types of channels than the second RF resource 112_2, the structure of the first RF resource 112_1 may be different from that of the second RF resource 112_2. In detail, the complexity of the structure of the first RF resource 112_1 may be greater than that of the second RF resource 112_2.

[0036] The first SIM 120_1 may receive at least one first channel 12 to use a first network service, and the second SIM 120_2 may receive at least one second channel 22 to use a second network service. In this case, the first SIM 120_1 and the second SIM 120_2 use RF resources to process the first channel 12 and the second channel 22, and in this case, the baseband processor 110 may selectively allocate any one of the first RF resource 112_1 and the second RF resource 112_2 to the first SIM 120_1 and the second SIM 120_2 based on information about the first network and the second network.

[0037] In an embodiment, the multi-SIM device 100 may operate in a dual radio (DR) mode or a dual SIM dual standby (DSDS) mode during resource allocation. The DR mode refers to an operation mode in which the first RF resource 112_1 and the second RF resource 112_2 may be allocated to the first SIM 120_1 and the second SIM 120_2, respectively, and communication operations are performed using the first RF resource 112_1 and the second RF resource 112_2. The baseband processor 110 may determine whether the multi-SIM device 100 operates in the DR mode based on information about the first network and the second network.

[0038] When it is determined that the multi-SIM device 100 can operate in DR mode, the baseband processor 110 may set either the first SIM 120_1 or the second SIM 120_2 as a primary SIM and the other as a secondary SIM, and then may allocate the primary SIM to the first RF resource 112_1 and the secondary SIM to the second RF resource 112_2. Figures 7 to 8B The method of setting the main SIM and the sub-SIM by the baseband processor 110 is described. For example, when the first SIM 120_1 is set as the main SIM and the second SIM 120_2 is set as the sub-SIM, the first SIM 120_1 can perform operations in a connection mode or an idle mode with the first network by processing the first channel 12 received from the first base station 10 using the first RF resource 112_1. The second SIM 120_2 can perform operations in an idle mode by processing the second channel 22 received from the second base station 20 using the second RF resource 112_2. The operation in the connection mode may include an operation of actively exchanging data (e.g., a voice or data call or session) with at least one base station in the wireless communication system 1, and the operation in the idle mode may include an operation of monitoring a channel with a periodic characteristic (e.g., a PCH or a BCH). In some embodiments, the operation in the idle mode may only include an operation of monitoring a channel with a periodic characteristic.

[0039] The multi-SIM device 100 according to the embodiment may operate in the DR mode when the RF resource use request interval of the first SIM 120_1 and the RF resource use request interval of the second SIM 120_2 overlap each other, and may allocate the first RF resource 112_1 and the second RF resource 112_2 to the first SIM 120_1 and the second SIM 120_2, respectively, thereby performing a communication operation using the first SIM 120_1 and the second SIM 120_2. In this case, the second RF resource 112_2 having low manufacturing cost and power consumption is used in the DR mode, and thus communication performance equal to or greater than a threshold level may be ensured.

[0040] When it is determined that the multi-SIM device 100 cannot operate in the DR mode, the baseband processor 110 may allocate the first RF resource 112_1 to any one of the first SIM 120_1 and the second SIM 120_2, and may control the selected one of the first SIM 120_1 and the second SIM 120_2 to operate in the DSDS mode. In addition, the multi-SIM device 100 may operate in DSDS as a legacy mode, and under certain conditions to be described in detail below, the multi-SIM device 100 may operate in the DR mode.

[0041] The information about the first network and the second network used to determine whether the multi-SIM device 100 can operate in the DR mode and set the primary SIM and the sub-SIM may include information about at least one first channel 12 between the first network and the first SIM 120_1, and information about at least one second channel 22 between the second network and the second SIM 120_2. That is, the information about the first channel 12 may include first channel configuration information indicating the type of the first channel 12, and when the first channel 12 is a channel having a periodic characteristic, the information about the first channel 12 may include first scheduling information about the first channel 12. In addition, the information about the second channel 22 may include second channel configuration information indicating the type of the second channel 22, and when the second channel 22 is a channel having a periodic characteristic, the information about the second channel 22 may include second scheduling information about the second channel 22.

[0042] The memory 130 may store information about the first network and information about the second network, and whenever the information about the first network and the information about the second network are updated, the memory 130 may store the updated information about the first network and the second network. The baseband processor 110 may access the memory 130 and read the information about the first network and the information about the second network, thereby performing operations according to one or more embodiments.

[0043] Figure 1 The multi-SIM device 100 is shown to include two SIMs, namely a first SIM 120_1 and a second SIM 120_2, and the baseband processor 110 includes two RF resources, namely a first RF resource 112_1 and a second RF resource 112_2. However, the multi-SIM device 100 may include more SIMs and more RF resources. It will be understood that one or more of the following embodiments may be applied to a multi-SIM device including three or more SIMs and / or three or more RF resources.

[0044] Figure 2 is a block diagram illustrating the baseband processor 110 in detail according to an embodiment.

[0045] Reference Figure 2 , the baseband processor 110 may include a first RF resource 112_1, a second RF resource 112_2, a DR / DSDS mode control module 114, and an RF resource manager 116. As described above, the first RF resource 112_1 may support the use of an unrestricted channel configuration, and the second RF resource 112_2 may support the use of a restricted channel configuration.

[0046] The DR / DSDS mode control module 114 can read the network related information 132 stored in the memory 130 and can determine whether the multi-SIM device can operate in the DR mode. The DR / DSDS mode control module 114 can control the multi-SIM device to operate in the DR mode or in the DSDS mode or maintain the DSDS mode according to the determination result. Figure 4 and Figure 5 A detailed embodiment of a method for setting a DR mode and a DSDS mode is described.

[0047] When the multi-SIM device is capable of operating in DR mode, the RF resource manager 116 may set one of the first SIM 120_1 and the second SIM 120_2 as a primary SIM and allocate the first RF resource 112_1 to the primary SIM based on network related information, and may set the other as a sub-SIM and allocate the second RF resource 112_2 to the sub-SIM. Figure 7 and Figure 8BA detailed embodiment of a method for allocating the first RF resource 112_1 and the second RF resource 112_2 to the first SIM 120_1 and the second SIM 120_2 in the DR mode is described in detail.

[0048] The memory 130 may store therein network related information 132, the network related information 132 including information about a first network corresponding to the first SIM 120_1 and information about a second network corresponding to the second SIM 120_2. The information about the first network may be generated based on at least one first channel received by the first SIM 120_1 from the first network, and the information about the second network may be generated based on at least one second channel received by the second SIM 120_2 from the second network.

[0049] Whenever the information about the first network of the first SIM 120_1 and the information about the second network of the second SIM 120_2 are updated, the network related information 132 may be updated and will be referred to. Figure 3 A detailed embodiment thereof is described.

[0050] In an embodiment, the DR / DSDS mode control module 114 and the RF resource manager 116 may be implemented as hardware logic in the baseband processor 110. In another embodiment, the DR / DSDS mode control module 114 and the RF resource manager 116 may be stored in the memory 130 as command codes and implemented as software logic executed by the baseband processor 110. However, these embodiments are only examples, and the inventive concept is not limited thereto. The first RF resource 112_1 and the second RF resource 112_2, the DR / DSDS mode control module 114 and the RF resource manager 116 may be implemented as various types of logic.

[0051] Figure 3 According to an embodiment, an update Figure 2 The flowchart of the method of network related information 132 is shown. Figure 2 Explanation Figure 3 Embodiment of the invention.

[0052] Reference Figure 3, in operation S10, the channel configuration information may be updated whenever channel configuration is performed. For example, the channel configuration information may be updated whenever channel configuration of one or more SIMs of the multi-SIM device is performed. In addition, the multi-SIM device may store the updated channel configuration information in the memory of the multi-SIM device so as to subsequently determine whether the multi-SIM device can operate in DR mode and allocate RF resources. The description of performing channel configuration of a SIM may refer to changing or newly adding a channel received from a network corresponding to the SIM. For example, a channel received from a first network may be changed, and a new allocation of RF resources may be performed on the first SIM 120_1 to enable channel configuration of the changed channel, thereby processing the changed channel. The first SIM 120_1 may update the channel configuration information and store the updated channel configuration information in the memory 130. As described above, the channel configuration information may indicate the type of a channel. For example, the updated channel configuration information may indicate the type of a new channel received from the network.

[0053] In operation S11, scheduling information may be updated. For example, in some embodiments, scheduling information about a channel having a periodic characteristic for each SIM of a multi-SIM device may be updated. In addition, the multi-SIM device may store the updated scheduling information in a memory of the multi-SIM device to subsequently determine whether the multi-SIM device can operate in DR mode and allocate RF resources. For example, as an operation in idle mode, the state of the SIM may be changed from a sleep state to an awake state within a specific interval, and the SIM may receive a PCH (or a paging message) or a BCH and then be switched to a sleep state. Immediately before the SIM is switched to the sleep state, scheduling information about a specific interval in which the SIM must be in an awake state to receive the next PCH or BCH (e.g., information about the timing when the state of the SIM changes to the next awake state or the timing when the awake state must be maintained) may be updated.

[0054] In addition, the multi-SIM device can update the frequency band information about the channel received by each SIM, and can update the strength information about the reference signal received by each SIM. The multi-SIM device can determine whether the DR mode is available based on the frequency band information, and update the reference signal strength information. Figure 5 and Figure 6 The detailed embodiments thereof are described. In addition, the multi-SIM device can perform base station (or cell) reselection, handover operation, etc. in idle mode based on the reference signal strength information. The embodiments described are only examples, and one or more embodiments are not limited thereto. The multi-SIM device can collect more types of information to effectively allocate RF resources supporting the use of non-restricted channel configuration and RF resources supporting the use of restricted channel configuration to SIMs, respectively, and can update the collected information.

[0055] Figure 4 According to the embodiment, it is used to explain a Figure 2 The flowchart of the method for allocating the first RF resource 112_1 and the second RF resource 112_2 is shown. Figure 2 Explanation Figure 4 Embodiment of the invention.

[0056] Reference Figure 2 and Figure 4 , in operation S100, the baseband processor 110 may receive an RF resource request from the first SIM 120_1. That is, the first SIM 120_1 may request RF resources to process a specific channel received from the first network. In operation S110, in response to the RF resource request, the DR / DSDS mode control module 114 may determine whether the DR mode can be set based on the network related information 132. When the DR mode can be set (operation S110, yes), the DR / DSDS mode control module 114 may set the multi-SIM device to be in the DR mode in operation S120, and the RF resource manager 116 may set the first SIM 120_1 as the main SIM and the second SIM 120_2 as the sub-SIM based on the network related information 132 in operation S130, and then the first RF resource 112_1 may be allocated to the first SIM 120_1. In operation S140, the baseband processor 110 may receive an RF resource request from the second SIM 120_2. That is, the second SIM 120_2 may request RF resources to process a specific channel received from the second network. In operation S150, the RF resource manager 116 may allocate the second RF resource 112_2 to the second SIM 120_2 in response to the RF resource request from the second SIM 120_2.

[0057] When the DR mode cannot be set (operation S110, No), the DR / DSDS mode control module 114 may maintain or set the operation mode of the multi-SIM device to the DSDS mode in operation S160, and may allocate the first RF resource 112_1 to the first SIM 120_1 in operation S170. In operation S180, the baseband processor 110 may receive an RF resource request from the second SIM 120_2. Since the multi-SIM device currently operates in the DSDS mode and the first RF resource 112_1 is allocated to the first SIM 120_1, the RF resource manager 116 may reject the RF resource request from the second SIM 120_2 in operation S190.

[0058] Figure 5 According to the embodiment, it is shown in detail Figure 4 The flowchart of operation S110 is shown in FIG. Figure 2 Explanation Figure 5 Embodiment of the invention.

[0059] Reference Figure 2 and Figure 5 , to perform operation S110( Figure 4 ), in operation S111, the DR / DSDS mode control module 114 may determine whether the RF resource usage request interval of the first SIM 120_1 overlaps with the RF resource usage request interval of the second SIM 120_2. The DR / DSDS mode control module 114 may determine whether the RF resource usage request interval of the second SIM 120_2 overlaps with the RF resource usage request interval of the first SIM 120_1 based on the network related information 132 and information about the RF resource usage request interval included in the RF resource request from the first SIM 120_1. In detail, when the channel received by the second SIM 120_2 is a channel having a periodic characteristic, the network related information 132 may include scheduling information about the channel received by the second SIM 120_2, and the DR / DSDS mode control module 114 may pre-identify the RF resource usage request interval of the second SIM 120_2 based on the scheduling information.

[0060] When the RF resource use request intervals overlap each other (operation S111, yes), the DR / DSDS mode control module 114 may determine in operation S112 whether the RF integrated circuit included in the multi-SIM device can simultaneously support the frequency band of the channel received by the first SIM 120_1 and the frequency band of the channel received by the second SIM 120_2. That is, the RF integrated circuit included in the multi-SIM device may support a limited number of frequency bands, and thus the multi-SIM device may determine whether the RF integrated circuit can cover the frequency band of the channel received by the first SIM 120_1 and the frequency band of the channel received by the second SIM 120_2. Information about the frequency bands that the RF integrated circuit can support may be pre-stored in the memory 130, and the network-related information 132 may also include information about the frequency band of the channel received by the first SIM 120_1 and the frequency band of the channel received by the second SIM 120_2. The DR / DSDS mode control module 114 may perform operation S112 based on the information stored in the memory 130.

[0061] When the RF integrated circuit can support the frequency bands at the same time (operation S112, yes), the DR / DSDS mode control module 114 can use the first RF resource 112_1 and the second RF resource 112_2 of the baseband processor 110 in operation S113 to determine whether the channel configuration can be processed at the same time. When the first RF resource 112_1 and the second RF resource 112_2 are respectively allocated to the first SIM 120_1 and the second SIM 120_2, the DR / DSDS mode control module 114 can determine whether the channel received by the first SIM 120_1 and the channel received by the second SIM 120_2 can be processed. For example, when the channel received by the first SIM 120_1 is a DCH and the channel received by the second SIM 120_2 is a DCH, it is possible that only the first RF resource 112_1 supports processing the DCH, and thus the channel received by the first SIM 120_1 and the channel received by the second SIM 120_2 may not be processed at the same time in the baseband processor 110. In addition, when the channel received by the first SIM 120_1 is a DCH and the channel received by the second SIM 120_2 is a PCH or a BCH, the first RF resource 112_1 may support processing of the DCH and the second RF resource 112_2 may support processing of the PCH or the BCH, and thus the channels may be processed simultaneously in the baseband processor 110. The DR / DSDS mode control module 114 may perform operation S113 based on the channel configuration information about the first SIM 120_1 and the channel configuration information about the second SIM 120_2, both of which are included in the network related information 132.

[0062] When the channel configuration can be processed simultaneously in the baseband processor 110 (operation S113, yes), operation S120 ( Figure 4 ), and when any of operations S111 to S113 is no, operation S160 ( Figure 4 ).

[0063] implement Figure 5 The order of operations S111 to S113 shown is only an example, and one or more embodiments are not limited thereto. Figure 5 The order of operations S111 to S113 shown may be changed. Some operations except operation S111 may be omitted, or other operations may be added.

[0064] Figure 6 A multi-SIM device 100 ′ is shown for explaining Figure 5 A block diagram of operation S112 is shown.

[0065] Reference Figure 6 ,and Figure 1Compared with the multi-SIM device 100 in the embodiment, the multi-SIM device 100′ may further include an RF integrated circuit 140. The structure of the multi-SIM device 100′ other than the RF integrated circuit 140 is the same as that of the multi-SIM device 100′. Figure 1 The structure is the same as in Figure 1 The RF integrated circuit 140 may include a first carrier component (CC1) 141 and a second carrier component (CC2) 142. The first carrier component 141 and the second carrier component 142 may be connected to an antenna AT (or an antenna array) to support beam forming. Each of the first carrier component 141 and the second carrier component 142 may receive a channel having a specific frequency band. In an embodiment, the frequency band supported by the first carrier component 141 may be the same as or different from the frequency band supported by the second carrier component 142.

[0066] The baseband processor 110 may determine whether the first channel 12 can be received from the first base station 10 through the first carrier component 141 and the second carrier component 142 of the RF integrated circuit 140, and whether the second channel 22 can be received from the second base station 20 through the carrier components. When the first channel 12 and the second channel 22 can be received through the first carrier component 141 and the second carrier component 142 of the RF integrated circuit 140, the baseband processor 110 may not perform operation S112 ( Figure 5 ). In other words, the baseband processor 110 may first determine whether the DR mode may be set by using hardware characteristics of the RF integrated circuit 140 instead of using information stored in the memory as described above with reference to operation S112. Figure 6 The structure of the RF integrated circuit 140 shown is only an example, and one or more embodiments are not limited thereto. The RF integrated circuit 140 may include a greater or lesser number of carrier components.

[0067] Figure 7 is a table TB for explaining a method of setting a main SIM and a sub-SIM according to an embodiment. Figure 2 It is assumed that a multi-SIM device is included in the WCDMA system. Figure 7 Embodiment of the invention.

[0068] Reference Figure 2 and Figure 7 , the RF resource manager 116 may set either the first SIM 120_1 or the second SIM 120_2 as a primary SIM and the other as a sub-SIM based on channel configuration information about a channel between the first SIM 120_1 and the first network and channel configuration information about a channel between the second SIM 120_2 and the second network, wherein both types of channel configuration information are included in the network related information 132 of the memory 130.

[0069] Referring to Table TB, in the first case (Case 1), when the channel between the first SIM 120_1 and the first network is DCH and the channel between the second SIM 120_2 and the second network is PCH, the RF resource manager 116 may set the first SIM 120_1 as the main SIM and the second SIM 120_2 as the sub-SIM. In the second case (Case 2), when the channel between the first SIM 120_1 and the first network is DCH and the channel between the second SIM 120_2 and the second network is PCH or BCH, the RF resource manager 116 may set the first SIM 120_1 as the main SIM and the second SIM 120_2 as the sub-SIM. That is, the RF resource manager 116 may set a SIM using a channel with a non-periodic characteristics (e.g., DCH) as the main SIM and allocate the first RF resource 112_1 to the main SIM, and may set a SIM using a channel with a periodic characteristic (e.g., PCH, BCH, etc.) as the sub-SIM and allocate the second RF resource 112_2 to the sub-SIM.

[0070] The third to sixth cases (cases 3 to 6) indicate that the main SIM and the sub SIM are set when the channel between the first SIM 120_1 and the first network and the channel between the second SIM 120_2 and the second network have periodic characteristics. In the third to sixth cases (cases 3 to 6), the RF resource manager 116 may set either the first SIM 120_1 and the second SIM 120_2 as the main SIM and the other as the sub SIM based on the scheduling information about the channel included in the network related information 132.

[0071] Fig. 8A and Figure 8B FIG. 1 is a diagram for explaining in detail a method for setting a main SIM and a sub-SIM according to an embodiment. Figure 2 Explanation Fig. 8A and Figure 8B Embodiment of the invention.

[0072] Reference Fig. 8A, the first SIM (SIM1) may be placed in a connected mode, and the second SIM (SIM2) may be placed in an idle mode. The second SIM 120_2 may receive a periodic channel periodic_CH in an awake state from a first time point t1 to a second time point t2. At the second time point t2, the state of the second SIM 120_2 may be changed to a sleep state and at the same time, scheduling information about the periodic channel periodic_CH may be updated in the memory 130, the scheduling information including information about a fourth time point t4 of the next awake state of the second SIM 120_2 and information about a period during which the awake state will be maintained. For example, when the periodic channel periodic_CH is a PCH, the scheduling information may include discontinuous reception (DRX) periodicity information.

[0073] In the connected mode, the first SIM 120_1 will receive the non-periodic channel Non_periodic_CH from the third time point t3, and at this time point, RF resource allocation may be performed for the first SIM 120_1. When receiving the RF resource allocation request from the first SIM 120_1, the RF resource manager 116 may pre-detect the interval OR_INT based on the network related information 132 of the memory 130 when the RF resource use request interval of the first SIM 120_1 and the RF resource use request interval of the second SIM 120_2 overlap each other, set the first SIM 120_1 as the main SIM at the third time point t3, allocate the first RF resource 112_1 to the main SIM, and set the second SIM 120_2 as the sub-SIM. The first SIM 120_1 may process the non-periodic channel Non_periodic_CH from the third time point t3 using the first RF resource 112_1.

[0074] Then, when the state of the second SIM 120_2 changes to the awake state at the fourth time point t4, the RF resource manager 116 may allocate the second RF resource 112_2 to the second SIM 120_2. The second SIM 120_2 may process the periodic channel periodic_CH using the second RF resource 112_2 from the fourth time point t4.

[0075] Reference Figure 8B, the first SIM 120_1 may be placed in idle mode, and the second SIM 120_2 may also be placed in idle mode. The second SIM 120_2 may receive the periodic channel periodic_CH in the awake state from the first time point t1 to the second time point t2. At the second time point t2, the state of the second SIM 120_2 may be changed to the sleep state and at the same time, the scheduling information about the periodic channel periodic_CH may be updated to the memory 130, the scheduling information including information about the sixth time point t6 of the awake state of the next second SIM 120_2 and information about the period during which the awake state will be maintained.

[0076] In the idle mode, the first SIM 120_1 may receive the periodic channel periodic_CH in the awake state from the third time point t3 to the fourth time point t4. At the fourth time point t4, the state of the first SIM 120_1 may be changed to the sleep state and at the same time, the scheduling information may be updated in the memory 130, the scheduling information including information about the fifth time point t5 of the awake state of the next first SIM 120_1 and information about the period during which the awake state will be maintained.

[0077] The first SIM 120_1 may receive the periodic channel periodic_CH from the fifth time point t5, and at this time point, the RF resource may be allocated to the first SIM 120_1. When receiving the RF resource allocation request from the first SIM 120_1, the RF resource manager 116 may use the network related information 132 of the memory 130 and may pre-detect the interval OR_INT when the RF resource use request interval of the first SIM 120_1 overlaps with the RF resource use request interval of the second SIM 120_2. The RF resource manager 116 may use the network related information 132 to recognize that the wake-up timing of the first SIM 120_1 (the fifth time point t5) is earlier than the wake-up timing of the second SIM 120_2 (the sixth time point t6), and therefore, the RF resource manager 116 may set the first SIM 120_1 as the main SIM and the second SIM 120_2 as the sub SIM.

[0078] The first SIM 120_1 may process the periodic channel periodic_CH from a fifth time point t5 using the first RF resource 112_1, and the second SIM 120_2 may process the periodic channel periodic_CH from a sixth time point t6 using the second RF resource 112_2.

[0079] Fig. 9 is a diagram for explaining the operation of the multi-SIM device 100 according to an embodiment. Fig. 9, assuming that the multi-SIM device 100 operates in DR mode, the first SIM 120_1 is set as the primary SIM, the first RF resource 112_1 is allocated to the first SIM 120_1, the second SIM 120_2 is set as the sub-SIM, and the second RF resource 112_2 is allocated to the second SIM 120_2.

[0080] Reference Fig. 9 , the first SIM 120_1 can receive and process a periodic channel or a non-periodic channel from the first base station 10 using the first RF resource 112_1, and the second SIM 120_2 can receive and process a periodic channel from the second base station 20 using the second RF resource 112_2.

[0081] Since the first SIM 120_1 uses the first RF resource 112_1 to process periodic channels or non-periodic channels when the second SIM 120_2 uses the second RF resource 112_2 to process periodic channels, the idle mode with the second base station 20 of the second network can be maintained, and in the idle mode, the second SIM 120_2 can perform reselection, handover operations, etc. to change the second base station 20 to the third base station 30.

[0082] Compared with the first RF resource 112_1, the second RF resource 112_2 according to the embodiment has advantages in manufacturing cost and power consumption, and can ensure that the communication performance of the multi-SIM device 100 is at least at a threshold level by performing an operation of maintaining the connection between the second SIM 120_2 and the second network using the second RF resource 112_2.

[0083] Fig.10 is a flowchart for explaining an operation of maintaining a DR mode according to an embodiment. Fig.11 It is used to explain in detail Fig.10 The diagram of operation S220 is shown in FIG. Figure 2 Explanation Fig.10 and Fig.11 Embodiment of the invention.

[0084] Reference Figure 2 and Fig.10 , in operation S120( Figure 4 ), the baseband processor 110 may update the channel configuration information of the first SIM 120_1 and the channel configuration information of the second SIM 120_2 in operation S200. In operation S210, the baseband processor 110 may receive an RF resource allocation request from the second SIM 120_2. In operation S220, the DR / DSDS mode control module 114 may determine whether the DR mode can be maintained based on the updated channel configuration information.

[0085] For example, further reference Fig.11 , the multi-SIM device can operate in DR mode, the first SIM 120_1 can be set as the main SIM, the first RF resource 112_1 can be allocated to the first SIM 120_1, the second SIM 120_2 can be set as a sub-SIM, and the second RF resource 112_2 can be allocated to the second SIM 120_2. The first SIM 120_1 can use the first RF resource 112_1 to process the non-periodic channel Non_periodic_CH from the first time point t1. The second SIM 120_2 can use the second RF resource 112_2 to process the periodic channel periodic_CH from the second time point t2 to the third time point t3. At the fourth time point t4, the second SIM 120_2 can receive the non-periodic channel Non_periodic_CH, and the channel configuration information about the second SIM 120_2 can be updated. The DR / DSDS mode control module 114 can determine whether the DR mode can be maintained based on the updated channel configuration information. Refer to Fig.11 , after the fourth time point t4, both the first SIM 120_1 and the second SIM 120_2 receive the non-periodic channel Non_periodic_CH, and thus the multi-SIM device may not be able to operate in the DR mode. In this case, the DR / DSDS mode control module 114 may determine that the multi-SIM device cannot maintain the DR mode, and may control the multi-SIM device to be in the DSDS mode.

[0086] Return to reference Fig.10 When the DR mode can be maintained (operation S220, yes), the DR / DSDS mode control module 114 may control the multi-SIM device to maintain the DR mode in operation S230. When the DR mode cannot be maintained (operation S220, no), the DR / DSDS mode control module 114 may control the multi-SIM device to change from the DR mode to the DSDS mode in operation S240.

Fig.12 The first RF resource 200_1 and the second RF resource 200_2 are shown to be applied to a WCDMA system, but this is only an example. The first RF resource 200_1 and the second RF resource 200_2 are not limited thereto and can be implemented to be applied to various communication systems.

[0088] Reference Fig.12, the first RF resource 200_1 may include a first lake processing circuit 210_1, a first deinterleaver 220_1, and a first decoder 230_1, and the second RF resource 200_2 may include a second lake processing circuit 210_2, a second deinterleaver 220_2, and a second decoder 230_2. In an embodiment, the structure of the first RF resource 200_1 may be different from the structure of the second RF resource 200_2, the first RF resource 200_1 may support the use of non-restricted channel configuration, and the second RF resource 200_2 may support the use of restricted channel configuration. Therefore, the complexity of the structure of the first RF resource 200_1 may be greater than the complexity of the structure of the second RF resource 200_2.

The second lake processing circuit 210_2 may include first to J-th fingers 212b_1 and first to L-th combinations 214b_1 and 214b_L. The second deinterleaver 220_2 may include first to N-th deinterleaver circuits 222b_1 and 222b_N.

[0090] The first lake processing circuit 210_1 of the first RF resource 200_1 may include a greater number of fingers and combinations than the second lake processing circuit 210_2 to receive and process a greater number of various channels than the second RF resource 200_2. The first deinterleaver 220_1 may include more deinterleaver circuits than the second deinterleaver 220_2. In addition, the first decoder 230_1 may decode a larger amount of data than the second decoder 230_2.

[0092] Reference Fig.13, the multi-SIM device 300 may include a baseband processor 210, a first SIM 220_1 to a G SIM 220_G, and a memory 230. The baseband processor 210 may include a first RF resource 212_1 to a G RF resource 212_G. The first RF resource 212_1 to the G RF resource 212_G are allocated to any one of the first SIM 220_1 to the G SIM 220_G, and may support the use of a non-restricted channel configuration or a restricted channel configuration according to an RRC protocol. For example, the first RF resource 212_1 may support the use of a non-restricted channel configuration, and the second RF resource 212_2 to the G RF resource 212_G may support the use of a restricted channel configuration.

[0093] When the RF resource request intervals of at least two target SIMs among the first SIM 220_1 to the G SIM 220_G overlap with each other, the baseband processor 210 may allocate some of the first RF resources 212_1 to the G RF resources 212_G to the target SIMs among the first SIM 220_1 to the G SIM 220_G based on information about networks respectively corresponding to the target SIMs among the first SIM 220_1 to the G SIM 220_G, and thus may support both the non-restricted channel configuration and the restricted channel configuration. In detail, the first RF resource 212_1 may be allocated to the target SIM that handles the non-periodic channel among the target SIMs to support the use of the non-restricted channel configuration, and the second RF resource 212_2 may be allocated to the other target SIMs to support the use of the restricted channel configuration.

[0094] Furthermore, as another embodiment, the first RF resource 212_1 may be allocated to a target SIM having a faster wake-up timing than other target SIMs in idle mode to support the use of an unrestricted channel configuration, and the second RF resource 212_2 may be allocated to other target SIMs to support the use of a restricted channel configuration.
