Electronic device supporting dual SIM and method of operation thereof

Various embodiments relate to an electronic device supporting two or more subscriber identity modules (SIMs) and an operating method thereof, and more particularly, to an electronic device supporting two or more SIMs for monitoring a paging message according to discontinuous reception (DRX). It relates to an apparatus and a method of operation thereof.

In a wireless communication system, an electronic device (eg, user equipment (UE)) may access a wireless communication network and use a voice communication or data communication service while in a predetermined location or while moving. In order to provide a communication service to an electronic device, an appropriate authentication process is required. A universal integrated circuit card (UICC) is inserted into the electronic device, and authentication is performed between the electronic device and the server of a mobile network operator (MNO) through a universal subscriber identity module (USIM) installed inside the UICC. This is done. UICC may be referred to as a subscriber identity module (SIM) card in the case of a global system for mobile communications (GSM) method, a universal subscriber identity module (USIM) card in the case of a wideband code division multiple access (WCDMA), and long term evolution (LTE) method. there is. The USIM card or the SIM card may exist in an independent UICC form, may exist in an embedded form in an electronic device (eg, embedded SIM, eSIM), or may exist in an integrated form (eg, in at least one of chips included in the electronic device). It may exist as an integrated SIM (iSIM).

When a user of an electronic device subscribes to a wireless communication service provided by a carrier, the carrier provides the user with a UICC (eg, a SIM card or a USIM card), and the user can insert the provided UICC into his or her electronic device. there is. According to an embodiment, when a user of the electronic device subscribes to a wireless communication service provided by a communication service provider, information to be stored in a UICC (eg, eSIM card or iSIM card) included in the electronic device may be received from the communication service provider. . When the UICC is inserted into the electronic device or receives information to be stored in the UICC from a communication service provider, the USIM application installed inside the UICC stores an international mobile subscriber identity (IMSI) value stored in the UICC and an encryption key value for authentication. An appropriate authentication process can be performed with the server of the telecommunication service provider in which the same value is stored using . After an appropriate authentication process is performed, the wireless communication service can be used.

When SIM-related information is provided to a UICC (eg, eSIM or iSIM) installed in the electronic device from a server of a communication service provider, the IMSI ( International mobile subscriber identity) value and an encryption key value for authentication may be used to perform an appropriate authentication process with a server of a telecommunication service provider in which the same value is stored. After an appropriate authentication process is performed, the wireless communication service can be used.

The electronic device may support two or more SIMs, and this may be referred to as a dual SIM (dual SIM) or a multi-SIM electronic device. Mounting two or more SIM cards in the electronic device may mean that at least two or more independent UICCs are configured. Alternatively, the mounting of two or more SIM cards in the electronic device may mean that the electronic device is composed of at least one independent UICC and at least one eSIM card. Alternatively, the mounting of two or more SIM cards in the electronic device may mean that the electronic device is composed of at least one independent UICC and at least one iSIM card.

According to various embodiments, an electronic device supporting a set of a plurality of DRX parameters capable of reducing a possibility of overlapping monitoring times may be provided.

In various embodiments, when the electronic device 101 performs a specific operation, at least one processor (eg, a communication processor) included in the electronic device 101 performs the specific operation or causes other hardware to perform the specific operation. It may mean controlling to perform Alternatively, when the electronic device 101 performs a specific operation, as an instruction stored in the memory 130 is executed, at least one processor (eg, a communication processor) performs a specific operation or causes other hardware to perform a specific operation. It may mean performing an action. Alternatively, when the electronic device 101 performs a specific operation, it may mean that an instruction for performing the specific operation is stored in the memory 130 .

According to various embodiments, in operation 401 , the electronic device 101 may receive system information from the first network for the first SIM. For example, the electronic device 101 may receive a system information block (SIB) (eg, SIB 1 ) from the first network. For example, DownlinkConfigCommonSIB may contain defaultPagingCycle. The defaultPagingCycle in 3GPP TS 38.331 may mean a default paging cycle used to derive a DRX cycle of a user equipment (UE) (eg, the electronic device 101) of the paging section of 3GPP TS 38.304. The value of rf32 of defaultPagingCycle corresponds to 32 radio frames, and the value of rf64 may correspond to 64 radio frames. For example, an integer (eg, 32, 64) added after rf is a radio frame. can mean the number of The value of rf32 of defaultPagingCycle corresponds to 32 radio frames, and the value of rf64 may correspond to 64 radio frames. For example, an integer (eg, 32, 64) added after rf is a radio frame. can mean the number of In the paging section (eg, 7.1 Discontinuous Reception for paging) of 3GPP TS 38.304, the smaller of the UE specific DRX value and the default DRX value set by the user equipment (UE) by RRC or upper layers is defined to set the DRX cycle. The DRX cycle used to determine the paging period may be a DRX value applied to an RRC idle state.

According to various embodiments, in operation 403 , the electronic device 101 may identify a first paging cycle for receiving a first paging message for the first SIM from the first network based on system information. For example, the electronic device 101 may identify the first paging cycle based on the default paging cycle included in the system information. Alternatively, the electronic device 101 may identify the first paging cycle based on a smaller value of a UE specific DRX cycle and a default paging cycle.

For example, when the electronic device 101 is powered on, the electronic device 101 may select a public land mobile network (PLMN). The selection procedure of the PLMN may be based on, for example, 3GPP TS 38.304, but there is no limitation. The electronic device 101 may, for example, receive system information from a suitable cell, and identify information necessary to perform camp on from the received system information. The electronic device 101 may select a suitable cell of the selected PLMN, and may camp on the selected appropriate cell. The electronic device 101 may establish a radio resource control (RRC) connection after camp-on in an appropriate cell. The electronic device 101 may, for example, receive system information from an appropriate cell and identify a default paging cycle from the received system information. According to various embodiments, the electronic device 101 may identify a default paging cycle from the received system information based on the system information received during the camp-on process. The electronic device 101 may, for example, perform a NAS (non access stratum) registration procedure and check a UE specific DRX cycle. For example, the electronic device 101 may In the process of performing the NAS registration procedure, a REGISTRATION REQUEST message may be transmitted and a REGISTRATION ACCEPT message corresponding to the registration request message may be received from the cell. For example, the user-specific DRX cycle information may be included in the registration permission message (REGISTRATION ACCEPT).

Although not shown, the network connection to the second SIM may also be performed in the step of connecting the network to the first SIM (eg, at least one of operation 401 and operation 403, or another time point).

According to various embodiments, in operation 405 , the electronic device 101 may determine whether a change in the first paging cycle is required. For example, the electronic device 101 may check whether the change of the first paging cycle is required in the RRC idle state after camp-on to the appropriate cell for the first time. Alternatively, the electronic device 101 may check whether a change in the first paging cycle is required in a state that is switched back to the RRC idle state after entering the RRC connected state by forming an RRC connection. . On the other hand, the state in which the electronic device 101 checks whether a change in the paging cycle is required may be any one of the RRC idle state, the RRC connected state, and the RRC inactive state, It will be understood by those skilled in the art that there is no limitation.

For example, when it is determined that both the first SIM and the second SIM are mounted, the electronic device 101 may determine that a change in the first paging cycle is required. For example, when it is confirmed that both the first SIM and the second SIM are activated, the electronic device 101 may determine that a change in the first paging cycle is required. When activation of two physical SIMs, activation of a physical SIM and a SIM supported by the eSIM, or activation of two SIMs supported by the eSIM is confirmed, the electronic device 101 determines that a change in the first paging cycle is required can For example, when it is confirmed that both the first SIM and the second SIM are activated, it may mean that at least one of user data and control data can be simultaneously transmitted and received from networks corresponding to the two SIMs. For example, confirming that both the first SIM and the second SIM are activated may mean that it is possible to receive a paging message from both networks corresponding to the two SIMs. For example, when it is determined that the first paging cycle corresponding to the first SIM and the second paging cycle corresponding to the second SIM overlap at least partially, or the overlapping time satisfies a specified condition In this case, the electronic device 101 may determine that the change of the first paging cycle is required. For example, the electronic device 101 determines the value of the first paging cycle corresponding to the first SIM and the value of the second paging cycle corresponding to the second SIM, which is confirmed based on the system information received through the cell corresponding to each SIM. When the values belong to the same DRX parameter set, the electronic device 101 may determine that the change of the first paging cycle is required. The electronic device 101 may receive and store at least one value of the first DRX parameter set and at least one value of the second DRX parameter set from each base station. A DRX parameter set is a set including a plurality of DRX parameter values, and may be referred to as DRX parameter values. Table 2 is an example of the first DRX parameter set and the second DRX parameter set. In the operation of the electronic device 101 receiving the first DRX parameter set and the second DRX parameter set from each base station, the operation of receiving system information of the base station through the first part of the electronic device 101, the electronic device 101 ) may include at least one of an operation of decoding the system information received through the second part and connecting with at least one or more parameters, and an operation of storing parameter information connected through the third part of the electronic device 101 .

According to various embodiments, the first DRX parameter set may be, for example, values settable as a request DRX parameter specified in 3GPP TS 24.501 (or values settable as a defaultpagingcycle). The second DRX parameter set may include values included in the first DRX parameter set and values satisfying a specified condition. For example, the value of the second DRX parameter set may be a sweep value with the value of the first DRX parameter set. For example, at least one of the values of the second DRX parameter set may be a sweep value with respect to at least one of the values of the first DRX parameter set. For example, the value of the second DRX parameter set may be a value in which the greatest common divisor with the value of the first DRX parameter set is less than the specified value (or the least common multiple is greater than the specified value). The values included in the first or second DRX parameter set of Table 2 are exemplary and may be changeable. For example, when the first paging cycle and the second paging cycle are included in the same DRX parameter set, the electronic device 101 may determine to change the first paging cycle. For example, when the first paging cycle and the second paging cycle are included in each of different DRX parameter sets, the electronic device 101 may determine not to change the first paging cycle. According to various embodiments, If it is determined that the change of the first paging cycle is required (405 - Yes), in operation 407 , the electronic device 101 first transmits a message including at least one of the first DRX parameter values or the second DRX parameter values. It can be transmitted over the network. For example, the electronic device 101 includes a value indicating at least one of the first DRX parameter values and the second DRX parameter values in a registration request (eg, registration request) message of 3GPP TS 24.501 and transmits it to the first network can do. For example, the electronic device 101 transmits the registration request (eg, registration request) message so that the first paging cycle corresponding to the first SIM and the second paging cycle corresponding to the second SIM are different DRX parameters, respectively. You can ask the network to be included in the set. If the second paging cycle corresponding to the second SIM is any one of the second DRX parameter values, the electronic device 101 may transmit a message including the first DRX parameter value to the first network. . If the second paging cycle corresponding to the second SIM is any one of the first DRX parameter values, the electronic device 101 may transmit a message including the second DRX parameter value to the first network. . The electronic device 101 may receive a message (eg, registration accept) corresponding to the transmitted message from the network, and based on information (eg, negotiated DRX parameter) included in the message received from the first network You can change 1 paging cycle. The electronic device 101 may monitor a physical downlink control channel (PDCCH) based on the changed first paging cycle. For example, when the electronic device 101 completes a registration procedure with the network and a preset timer expires thereafter, the RRC connection may be released. The electronic device 101 may monitor the PDCCH based on the changed first paging cycle in the RRC idle state or the RRC inactive state. The electronic device 101 may calculate a paging frame (PF) and a frame occasion (PO) based on the changed first paging cycle T, and may perform paging monitoring based on the calculation result. The calculation process may follow, for example, 3GPP TS 38.304. PF may mean a frame in which a paging-related PDCCH can be transmitted, and PO may mean a slot or a symbol in which a paging-related PDCCH can be transmitted in the PF. The paging monitoring operation includes an operation of decoding a paging-related PDCCH using the P-RNTI allocated by the electronic device 101 in the calculated PF and PO, an operation of performing a CRC check based on the decoding result, and an operation of performing a paging-related PDCCH scheduling. This may mean including at least one of an operation of decoding data included in the PDSCH and an operation of checking whether the ID of the electronic device 101 is included based on the decoded data.

According to various embodiments, if it is determined that the change of the first paging cycle is not required (405 - No), the electronic device 101 determines whether the first paging message exists based on the first paging cycle in operation 409 . can be monitored. For example, at least a portion of the first paging message may be transmitted through the PDCCH. For example, when the electronic device 101 completes a registration procedure with the network and a preset timer expires thereafter, the RRC connection may be released. The electronic device 101 may monitor the PDCCH based on the first paging cycle in the RRC idle state or the RRC inactive state. According to the above-described process, for example, the first paging cycle and the second paging cycle may be included in different DRX parameter sets. Since the value of the first DRX parameter set and the value of the second DRX parameter set are set to have a specified condition (eg, small relative to each other), the number of overlapping monitoring times (eg, POs) of both SIMs can be reduced. .

According to various embodiments, in operation 501 , the electronic device 101 may identify a first paging cycle for receiving the first paging message from the first network for the first SIM. In operation 503 , the electronic device 101 may identify a second paging cycle for receiving the second paging message from the second network for the second SIM. The electronic device 101 identifies the first paging cycle based on at least one of the system information or the user device specific DRX parameter received from the first network, and the system information or the user device specific DRX parameter received from the second network. The second paging cycle may be identified based on at least one of

According to various embodiments, in operation 505 , the electronic device 101 may determine whether the first paging cycle and the second paging cycle satisfy a specified condition. For example, the electronic device 101 may check whether each of the first paging cycle and the second paging cycle is included in each of the first DRX parameter set and the second DRX parameter set of Table 2 . Alternatively, the electronic device 101 may check whether the first paging cycle and the second paging cycle are equal to each other, or whether the greatest common divisor is less than the specified number (or whether the minimum common multiple is greater than the specified number).

According to various embodiments, if it is determined that the specified condition is not satisfied (505 - No), according to various embodiments, the electronic device 101 performs at least one of the first paging cycle and the second paging cycle in operation 507 , according to various embodiments. A message (eg, registration request) including at least one of the first DRX parameter values or the second DRX parameter values for adjustment may be transmitted to the first network. The electronic device 101 may receive a message (eg, registration accept) corresponding to the transmitted message from the network, and perform the first paging cycle based on information (eg, negotiated DRX parameter) included in the received message. can be changed For example, as in FIG. 3 , the first paging cycle T1 corresponding to the first SIM (SIM1) is set to 320 ms, and the second paging cycle T2 corresponding to the second SIM (SIM2) is 640 ms. can be set to In this case, the electronic device 101 may determine that both paging cycles T1 and T2 are included in the first DRX parameter set, and determine that the specified condition is not satisfied. Alternatively, the electronic device 101 determines that 320 ms, which is the maximum common divisor of both paging cycles T1 and T2, is equal to or greater than the critical common multiple (or 640 ms, which is the least common multiple, is less than or equal to the critical common multiple) based on the fact that the specified condition is not satisfied. You can also check that it is not. Accordingly, the electronic device 101 may transmit, for example, a message requesting a change of the second paging cycle T2 (eg, a registration request) to the second network. The message may include a value (eg, 360 ms) included in the second DRX parameter set. When receiving a message (eg, registration accept) including a value included in the second DRX parameter set as a negotiated DRX parameter from the second network, the electronic device 101 performs a second paging cycle T2 as shown in FIG. 6 . It may be changed to the third paging cycle T3 (eg, 360 ms). Monitoring time (601,602,603) of the first SIM (SIM1), in that the greatest common divisor (eg 40 ms) of the first paging cycle (T1) (eg 320 ms) and the third paging cycle (T3) (360 ms) is less than the critical common divisor (601,602,603) The number of overlapping times with the

monitoring times

611 , 612 , and 613 of the second SIM SIM2 may be reduced compared to that of FIG. 3 . If it is confirmed that the specified condition is satisfied (505 - Yes), in operation 509 , the electronic device 101 monitors the first paging message based on the first paging cycle and performs a second paging based on the second paging cycle. Messages can be monitored. For example, the operation of monitoring the paging message may include the operation of monitoring the PDCCH corresponding to each paging message.

According to various embodiments, in operation 701 , the electronic device 101 sets one of the first DRX parameter values as the first paging cycle to receive the first paging message from the first network for the first SIM. You can make a request to the first network. In operation 703 , the electronic device 101 may request the second network to set one of the second DRX parameter values as the second paging cycle in order to receive the second paging message from the second network for the second SIM. there is. For example, upon confirming that the first SIM and the second SIM are activated, the electronic device 101 requests the network to use any one of the first DRX parameter values in response to the first SIM through a registration process, , in response to the second SIM, may request the network to use any one of the second DRX parameter values through a registration process. According to the above-described process, for example, the first paging cycle and the second paging cycle may be included in different DRX parameter sets. Since the value of the first DRX parameter set and the value of the second DRX parameter set are set to have a specified condition (eg, small relative to each other), the number of overlapping monitoring times (eg, PO) may be reduced. In the above-described embodiment, the electronic device 101 does not check whether a change of a specific SIM is requested, but requests any one of the first DRX parameter sets from the network in response to the first SIM, and performs the second In response to the SIM, it may be configured to request a value of any one of the second DRX parameter sets from the network.

RRC connection setup completion may include, for example, a registration request message defined in 3GPP TS 24.501. According to 3GPP TS 24.501, the registration request message is a message transmitted from the user equipment (UE) to the core network (eg, the AMF 217), and may include an information element of requested DRX parameters. Table 3 shows information elements of requested DRX parameters of an IEI (information element identifier) of "51" defined in 3GPP TS 24.501.

As shown in Table 3, the requested DRX parameters of the IEI of "51" are referenced by 9.11.3.2A of 3GPP TS 25.401, presence or absence is optional, and TLV (type-length-value) , and can have a length of 3 octets. According to 9.11.3.2A of 3GPP TS 25.401, the purpose of the requested DRX parameters is to indicate that the user equipment (UE) wants to use DRX. Table 4 is a coding example of requested DRX parameters.

The first octet (octet 1) of the requested DRX parameters may include an IEI (eg, 51), the second octet (octet 2) may include a length, and the third octet (octet 3) may include a DRX value. and a spare bit may be included. DRX values are shown in Table 5 below.

The DRX value may represent 32 when bits 4 to 1 are "0001", 64 when "0010", 128 when "0011", and 256 when "0100". Bits 5 to 8, which are other bits, are reserved bits, and may be coded as 0, for example. According to various embodiments, the registration request message may include an information element of requested DRX parameters2. As requested DRX parameters2 is not defined in the current 3GPP TS 24.501, IEI, presence, format, and length are not defined, but may be defined in the registration request message in a format similar to the requested DRX parameters.

Table 6 shows information elements of requested DRX parameters2.

As shown in Table 6, IEI is not defined in the current 3GPP TS 25.401. The requested DRX parameters2 is not defined in 3GPP TS 25.401, but if it is related to 9.11.3.2 of the requested DRX parameters, it may be defined as the item of 9.11.3.2B. Whether or not the requested DRX parameters2 exists may be optional, and the requested DRX parameters2 has a type-length-value (TLV) format and may have a length of 3 octets. If 9.11.3.2B of 3GPP TS 25.401 is defined, then the purpose of requested DRX parameters2 is to indicate that the user equipment (UE) wants to use DRX. Table 7 is a coding example of requested DRX parameters2.

The first octet (octet 1) of the requested DRX parameters2 may include the IEI, the second octet (octet 2) may include the length, and the third octet (octet 3) includes the DRX value and spare. bits may be included. DRX values are shown in Table 8 below.

The DRX value may represent 36 when bits 4 to 1 are "0001", 72 when "0010", 144 when "0011", and 288 when "0100". For example, the requested DRX parameters2 may be values of the second DRX parameter set of Table 2, but this is exemplary and is not limited. Bits 5 to 8, which are other bits, are reserved bits, and may be coded, for example, as 0. The electronic device 101 according to various embodiments may use the IEI of “51” of the registration request to display the first DRX of Table 2 Any one of the parameter sets may be requested from the network 800 . The electronic device 101 may request one of the values of the second DRX parameter set of Table 2 from the network 800 by using the IEI of the requested DRX parameters2 of the registration request. 3 , a paging cycle of a value (eg, 320 ms) included in the first DRX parameter set is set for the first SIM, and a value included in the first DRX parameter set (eg, 640 ms) for the second SIM ), it is assumed that the paging cycle is set. As shown in FIG. 6 , the electronic device 101 may request the network 800 for a paging cycle of a value included in the second DRX parameter set of 360 ms for the second SIM. In this case, the electronic device 101 may transmit a registration request message including the coded information shown in Table 9 to the network 800 .

According to various embodiments, the electronic device 101 may not distinguish the first DRX parameter and the second DRX parameter as different IEIs. For example, the electronic device 101 may distinguish the first DRX parameter and the second DRX parameter by including the indicator in the registration request. For example, Table 10 may be coded information related to DRX and parameters included in the registration request.

In Table 10, bit 5 of the spare bit may have a value of “1”, and the DRX value may be “0001”. The electronic device 101 may use bit 5 of the reserved bit of the current 5GS DRX parameters IEI as an indicator. For example, when bit 5 of the reserved bit is “1”, it may mean the first DRX parameter set, and when bit 5 of the reserved bit is “0”, it may mean the second DRX parameter set. In the case of Table 10, 320 ms corresponding to “0001” among the first DRX parameter set may be set as the requested DRX parameter. If bit 5 of the spare bit of Table 10 has a value of “0” and the DRX value is “0001”, 360 ms corresponding to “0001” in the second DRX parameter set is the requested DRX parameter. can be set. Meanwhile, it is exemplary that bit 5 of the reserved bits is used as an indicator, and at least some of the reserved bits may be used as an indicator. In addition, the use of the reserved bit as an indicator is also exemplary, and there is no limitation on the expression method of the indicator. In another embodiment, as shown in Table 11, values of the first DRX parameter set and the values of the second DRX parameter set All values may be representable in one IEI (eg, IEI of "51").

The electronic device 101 according to various embodiments may request values included in the first DRX parameter set using values of “0001”, “0010”, “0011”, and “0100”, and may include “0101”, The values included in the second DRX parameter set may be requested by using the values of “0110”, “0111”, and “1000”. Meanwhile, the numbers “0001”, “0010”, “0011”, “0100”, 0101”, “0110”, “0111”, and “1000” are merely exemplary, and there is no limitation. , the electronic device 101 according to various embodiments may transmit a registration request message requesting at least one of the first DRX parameter set and at least one of the second DRX parameter set to the network 800 . . According to various embodiments, the network 800 may transmit a registration accept to the electronic device 101 in operation 813. According to 3GPP TS 24.501, the network 800 may transmit a registration accept to the network (eg, FIG. 2 ). This is a message transmitted from the AMF 217 of 217)) may include the IE of the negotiated DRX parameters in the registration accept message. The AMF (eg AMF 217) may set the negotiated DRX parameters based on the received requested DRX parameters. If possible, The AMF (eg, the AMF 217 ) may set negotiated DRX parameters based on an operator policy and the received requested DRX parameters.

Table 12 shows information elements of negotiated DRX parameters of IEI of "51" defined in 3GPP TS 24.501.

As shown in Table 12, the negotiated DRX parameters of the IEI of "51" are referenced by 9.11.3.2A of 3GPP TS 25.401, the presence or absence of an optional (optional), TLV (type-length-value) , and can have a length of 3 octets. According to 9.11.3.2A of 3GPP TS 25.401, the purpose of the negotiated DRX parameters is to cause the network 800 to indicate the DRX cycle value used for paging. The negotiated DRX parameters can be coded in the same way as the requested DRX parameters in Table 5. For example, the first octet (octet 1) of the negotiated DRX parameters may include an IEI (eg, 51), the second octet (octet 2) may include a length, and the third octet (octet 3) may include ) may include a DRX value and a spare bit. The DRX value may be as shown in Table 5 above. For example, as shown in Table 5, a negotiated DRX cycle parameter may be expressed by bits 4 to 1. The DRX value may represent 32 when bits 4 to 1 are "0001", 64 when "0010", 128 when "0011", and 256 when "0100". Bits 5 to 8, which are other bits, are reserved bits, and may be coded as 0, for example. According to various embodiments, the registration accept message may include an information element of negotiated DRX parameters2. Since negotiated DRX parameters2 is not defined in the current 3GPP TS 24.501, IEI, presence, format, and length are not defined, but may be defined in a registration accept message in a format similar to negotiated DRX parameters.

Table 13 shows the information element (information element) of the negotiated DRX parameters2.

As shown in Table 13, IEI is not defined in the current 3GPP TS 25.401. Although negotiated DRX parameters2 is not defined in 3GPP TS 25.401, if it is related to 9.11.3.2 of negotiated DRX parameters, it may be possible to define it as an item of 9.11.3.2B. The presence or absence of negotiated DRX parameters2 may be optional, and negotiated DRX parameters2 may have a type-length-value (TLV) format and may have a length of 3 octets. If 9.11.3.2B of 3GPP TS 25.401 is defined, the purpose of negotiated DRX parameters2 is to allow the network 800 to indicate the DRX cycle value used in paging. Coding of negotiated DRX parameters2 may be, for example, as shown in Table 7. For example, IEI may be included in the first octet (octet 1) of negotiated DRX parameters2, and length may be included in the second octet (octet 2). ) may be included, and the third octet (octet 3) may include a DRX value and a spare bit. The DRX value may be the same as in Table 8 described above. As shown in Table 8, DRX cycle parameters for negotiated DRX parameters2 may be expressed by bits 4 to 1. The DRX value may represent 36 when bits 4 to 1 are "0001", 72 when "0010", 144 when "0011", and 288 when "0100". For example, the negotiated DRX parameters2 may be at least one of the values of the second DRX parameter set in Table 2, but this is illustrative and not limited. The other bits, bits 5 to 8, may be coded as reserved bits, for example 0.

The network 800 according to various embodiments may transmit a value of any one of the first DRX parameter sets of Table 2 to the electronic device 101 by using the IEI of “51” of the negotiated request. The network 800 may transmit any one of the second DRX parameter sets of Table 2 to the electronic device 101 by using the IEI of the negotiated DRX parameters2 of the registration accept.

According to various embodiments, the network 800 may not distinguish the first DRX parameter and the second DRX parameter as different IEIs. For example, the network 800 may distinguish the first DRX parameter and the second DRX parameter by including the indicator in the registration accept. For example, the coded information shown in Table 10 may be included in the registration accept. As described in Table 10, bit 5 of the spare bit may have a value of “1”, and the DRX value may be “0001”. The network 800 may use bit 5 of the reserved bit as an indicator. For example, when bit 5 of the reserved bit is “1”, it may mean the first DRX parameter set, and when bit 5 of the reserved bit is “0”, it may mean the second DRX parameter set. In the case of Table 10, 320 ms corresponding to “0001” among the first DRX parameter set may be set as the requested DRX parameter. If bit 5 of the spare bit of Table 10 has a value of “0” and the DRX value is “0001”, 360 ms corresponding to “0001” in the second DRX parameter set is the requested DRX parameter. can be set. Meanwhile, it is exemplary that bit 5 of the reserved bits is used as an indicator, and at least some of the reserved bits may be used as an indicator. In addition, the use of the reserved bit as an indicator is also exemplary, and there is no limitation on the expression method of the indicator.

In addition, the requirement for unaligned DRX may mean that values included in different DRX parameter sets for each of the first SIM and the second SIM need to be set as a paging cycle. For example, the electronic device 101 may confirm that any one of the first DRX parameter sets for the first SIM is set as the paging cycle, and correspondingly, among the second DRX parameter sets for the second SIM It can be seen that any one value needs to be set as the paging cycle. The condition for which unaligned DRX is required may include, for example, at least some of the conditions for determining whether a change in the paging cycle described with reference to FIG. 4 is required.
