[0025] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0037] Figure 11 A structural block diagram of a computer device according to an embodiment of the present disclosure is shown. Detailed Implementation

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0040] The solution provided in this application allows the first SIM card to continue residing on the SA network when it detects that the second SIM card is in VoLET voice service mode. This is achieved by reporting the radio capability that can only reside on the SA network. For dual-SIM terminals that only support SA+LTE mode, this prevents the first SIM card from preempting the second SIM card's LTE network resources due to falling back to the LTE network, which could lead to issues such as call reconstruction and dropped calls when the second SIM card is in VoLET voice service mode. This improves the stability of dual-SIM dual-pass terminals when performing VoLET voice services and enhances the user experience.

[0041] To facilitate understanding, the terms (abbreviations) used in this application will be explained below.

[0042] VoLTE stands for Voice over Long-Term Evolution, which means a high-speed wireless communication standard for mobile phones and data terminals.

[0043] DRX stands for Discontinuous Reception. This method allows the UE to periodically enter sleep mode at certain times, not listening to PDCCH subframes. When listening is needed, it is woken up from sleep mode, thus saving power for the UE.

[0044] PSM, or Power Saving Mode, is a power-saving mode. In PSM mode, the device is essentially turned off, thus saving even more power.

[0045] Mobility Registration update: UE re-registration when entering a new TA that is not in the TAI LIST.

[0046] TAI LIST: Tracking Area Identity, a list of tracking area identifiers.

[0047] TA: TrackingArea. A tracking area refers to the tracking area in which the core network knows the location of the UE when the UE is in an idle state. At the same time, when the idle UE needs to be paged, paging must be performed in all cells of the tracking area in which the UE is registered.

[0048] Multiple TAs form a TA list and are assigned to a UE. When the UE moves within the TA list, it does not need to perform a TA update to reduce frequent interactions with the network. When the UE enters a new TA area that is not in its registered TA list, it needs to perform a TA update. The MME reassigns a new set of TAs to the UE. The newly assigned TAs may also include some TAs from the original TA list. Each cell belongs to only one TA.

[0049] NSA: Non-Standalone; SA: Standalone.

[0050] NR: 5G New Radio.

[0051] RRC: Radio Resource Control.

[0052] gNB: A node that provides NR user plane and control plane protocol terminals to UEs and connects to 5GC (5G core network) via the NG interface.

[0053] NG-eNB: A node that provides E-UTRA user plane and control plane protocol terminals to the UE and connects to the 5GC via the NG interface.

[0054] MME: Mobility Management Entity.

[0055] AMF: Access and Mobility Management Function.

[0056] The following will describe in more detail each step of the dual-SIM terminal network scheduling method in this exemplary embodiment, with reference to the accompanying drawings and embodiments.

[0057] A network scheduling scheme for dual-SIM terminals according to an embodiment of this disclosure is applicable to, but not limited to, dual-SIM terminals. For example... Figure 1 As shown, the system for performing network scheduling for dual-SIM terminals includes:

[0058] The dual-SIM terminal 102 includes a first SIM1 and a second SIM2. The first SIM supports both SA and LTE networks, while the second SIM supports LTE networks.

[0059] The second SIM card accesses the core network device 108 through the access network device eNB, and the first SIM card accesses the core network device 108 through the access network device gNB106. The core network device 108 can be either an AMF or an MME.

[0060] like Figure 2 As shown, a dual-SIM terminal network scheduling method according to an embodiment of this disclosure is applied to a terminal. The dual-SIM terminal is loaded with a first SIM card and a second SIM card. The first SIM card can reside on an SA network or an LTE network, and the second SIM card resides on an LTE network. The method includes:

[0061] Step S202: When it is detected that the second card is performing Long Term Evolution (LTE) VoLET voice service and the first card is in RRC_IDLE state or RRC_INACTIVE state, the first card reports the radio capabilities corresponding to the voice service to the network device of the first card. The radio capabilities are used to indicate that the first card is camped on the SA network when the second card is performing VoLET voice service.

[0062] Specifically, designate the first card as the main card and the second card as the supplementary card.

[0063] In addition, in the RRC_IDLE state, the services provided by the network to the UE include limited services, normal services, and carrier services; in the RRC_INACTIVE state, the services provided by the network to the UE include normal services and carrier services.

[0064] In this embodiment, when the first SIM card detects that the second SIM card is in VoLET voice service mode, it reports its radio capability that can only camp on SA network to continue camping on SA network. For dual-SIM terminals that only support SA+LTE mode, this prevents the first SIM card from falling back to LTE network and preempting the second SIM card's LTE network resources, which could cause problems such as call reconstruction and dropped calls when the second SIM card is in VoLET voice service mode. This helps to improve the stability of dual-SIM dual-pass terminals when performing VoLET voice service and improves the user experience.

[0065] In one embodiment, the network device of the first card includes the access network device and the core network device of the first card. The access network device is specifically a gNB, and the core network device can be an AMF or an MME.

[0066] like Figure 3 As shown, in step S202, a specific implementation method for reporting the wireless capabilities of the first card corresponding to the voice service to the network device of the first card includes:

[0067] Step S302: Send a registration update request to the network device. The registration type of the registration update request is MobilityRegistration Update. The registration update request carries a UE Radio Capability Update indication. The UE Radio Capability Update indication is used to instruct the network device to update the stored radio capability of the first card to continue camping on the SA network. The UE Radio Capability Update indication is also used to indicate that the first card can accept camping on NR cells.

[0068] Among them, wireless capability refers to UE capability, that is, UE capability. After the access network equipment obtains the UE capability, it makes the correct scheduling of the UE. If the UE supports a certain function, the base station can configure the UE with that function. If the UE does not support a certain function, the base station cannot configure the UE with that function. By reporting to the access network equipment and core network equipment that the first card can only camp on the SA network, the first card can only perform cell reselection operation based on the UR cell.

[0069] UE Capability mainly involves two processes: UE Capability Request and UE Capability Reporting. When the access network device needs the UE to report UE Capability, the access network device will send a UECapabilityEnquiry command to the UE. After receiving the UECapabilityEnquiry command, the UE will report the UE CapabilityInformation according to the command.

[0070] Step S304: Perform cell reselection operation for the first card so that the first card can continue to camp on the SA network.

[0071] Specifically, when the terminal powers on, it performs an initial registration operation. At this time, the terminal reports the RAT (Radio Access Technology) related capabilities of the first card, the associated terminal identifier, and the information of the second card, etc., to the network device. When the first card, which is in 5G SA data service mode, receives a VoLTE MT call from the network side, before the Trigger for Fallback and optional measurement report solicitation, the base station does not perform Handover base station transfer or redirection for the first card to prevent the first card from falling back to 4G. At the same time, it triggers the optimized scheduling process. The base station searches for the identifiers of the two cards as associated with the same terminal in the UE Assistance Information reported by the terminal in the AMF network element, identifies the user of the second card who is associated with the same terminal as the first card, and sends the SIP Invite paging message for this VoLTE MT call after verification, and establishes IMS VoLTE Session Setup.

[0072] In addition, the terminal negotiates with the network to update the UE Radio Capability Update instruction to SA mode, i.e., RAN-Type: NR, and continues to be registered in the NR cell.

[0073] Based on the registration update request, the UE sends an AN message to the access network device. The AN message includes an AN message and a Registration Request. The Registration Request includes information such as Registration type, SUCI or GUTI or PEI, the TAI of the last access, and security parameters.

[0074] The Registration type indicates the type of registration, including Initial Registration, Mobility Registration Update, Periodic Registration Update, and Emergency Registration.

[0075] During power-on, Initial Registration is typically performed. In the scheme disclosed herein, when the second card is detected to be performing VoLET voice service, the registration type performed by the first card is Mobility Registration Update.

[0076] In this embodiment, when the second SIM card is detected to be in VoLTE voice service execution state, a registration update request is sent from the access network device to the core network device. The registration update request carries the radio capability of the first SIM card under the current operating condition, that is, it can only camp on NR cells. After the core network receives the registration update request, it updates the TAI List, which only includes NR cells. Thus, when the first SIM card performs cell reselection operation, it can only camp on NR cells, preventing the first SIM card from falling back to the 4G network. On the one hand, this avoids preempting the LTE radio frequency resources used by the second SIM card's VoLTE service, improving the reliability of the second SIM card's voice calls. On the other hand, it can effectively guarantee the performance of the first SIM card's 5G NR data service, thereby ensuring the excellent dual-pass performance of the dual-SIM terminal.

[0077] like Figure 4 As shown, in one embodiment, it further includes:

[0078] Step S402: Receive the registered tracking area sent by the access network device based on its wireless capabilities.

[0079] The cell reselection operation is performed based on the first SIM card, specifically including:

[0080] Step S404: Perform cell reselection according to the cell reselection criteria to determine the NR cells that can be used for camping.

[0081] NR cells are 5G network cells.

[0082] Step S406: Detect whether the NR cell that can be camped belongs to the registered tracking area.

[0083] Step S408: When the NR cell where the card can be camped is in a registered tracking area, the card is camped on the NR cell where the card can be camped.

[0084] In step S410, when the NR cell that can be camped is not in the registered tracking area, for the RRC_IDLE state, a location update request is sent from the access network device to the core network device; for the RRC_INACTIVE state, an RNA update process is performed based on the NR cell that can be camped.

[0085] Specifically, if the VoLET voice service status of the first UE based on the second UE cannot camp on the current cell, a cell reselection operation needs to be performed. According to the cell reselection criteria, the UE may perform cell reselection and attempt to camp on a new cell. If the new cell does not belong to the registered tracking area, the location update process will be performed again. In the RRC_INACTIVE state, if the new cell does not belong to the configured RNA, the RNA update process will be performed.

[0086] In the RRC_IDLE and RRC_INACTIVE states, the UE's cell camping has the following four main aspects: (1) The UE can receive system messages under the current PLMN; (2) When the UE wants to establish an RRC connection or restore a suspended RRC connection, the UE can initiate initial access on the cell control channel where it camps; (3) If the network needs to send messages or transmit data to the registered UE, the network usually knows the tracking area (in the RRC_IDLE state) or RNA (in the RRC_INACTIVE state) where the UE camps, and the network can send a paging message to the UE. The UE can receive the paging message and respond; (4) The UE can receive ETWS and CMAS notifications.

[0087] In this embodiment, when a campable NR cell is detected based on the cell reselection criteria, it is further detected whether the campable NR cell belongs to the registered tracking area, so that the camping of the NR cell is performed only based on the detection result, thereby ensuring that the first SIM card will not fall back to the 4G network.

[0088] like Figure 5 As shown, the cell reselection operation based on the first card specifically includes:

[0089] Step S502: Perform cell reselection according to the cell reselection criteria to determine the NR cells that can be used for camping.

[0090] Step S504: Detect whether the NR cell that can be camped belongs to the registered tracking area.

[0091] Step S506: When the NR cell where the card can be camped is in a registered tracking area, the card is camped on the NR cell where the card can be camped.

[0092] Step S508: When the NR cell that can be camped is not in the registered tracking area, for the RRC_IDLE state, a location update request is sent from the access network device to the core network device; for the RRC_INACTIVE state, an RNA update process is performed based on the NR cell that can be camped.

[0093] Step S510: Measure the signal strength RSRP of the campable NR cell.

[0094] Step S512: Based on RSRP, detect whether the available NR cells meet the network selection conditions for the first SIM card.

[0095] Step S514: When the network selection conditions are met in the available NR cell, continue to camp on the available NR cell based on the first SIM card.

[0096] In this embodiment, when a campable NR cell is detected, the signal strength RSRP of the campable NR cell is further measured to detect whether the current network environment meets the network selection conditions of the first SIM card based on the signal strength RSRP. If the conditions are met, the card camps on the new NR cell; if not, the card continues to camp on the current NR cell, but the operating status is configured.

[0097] In one embodiment, it also includes:

[0098] Step S516: When the NR cell that can be camped does not meet the network selection conditions, configure the first card to operate based on the discontinuous reception DRX mechanism.

[0099] Specifically, after a UE completes its camping in the current NR cell, it can be said that the UE has entered the "idle state" or "idle state". If the UE subsequently completes the random access procedure, it can be said that the UE has entered the "connected state" or "connected state". Whether it is the idle state or the connected state, by setting the DRX mechanism, it is possible to save power for the UE while ensuring effective data transmission.

[0100] A DRX cycle equals the sum of the UE's wake-up time and sleep time. The system can configure either a short or long DRX cycle for the UE based on different service scenarios. For example, during VoIP services, the voice codec typically sends a VoIP packet every 20ms, so a 20ms short DRX cycle can be configured. During longer silence periods in a voice call, a long DRX cycle can be configured. If both short and long cycles are configured simultaneously, and the drxShortCycleTimer times out, the UE will enter a long DRX cycle.

[0101] In this embodiment, by configuring the DRX mechanism on the first card, the first card can achieve power saving function while residing in the SA network, thereby ensuring the reliable execution of the VoLET voice service of the second card.

[0102] In one embodiment, it also includes:

[0103] Step S518: When the NR cell that can be camped does not meet the network selection conditions, the first card is controlled to enter the power saving mode based on the first timer and the second timer.

[0104] Specifically, such as Figure 6 As shown, the first card is controlled to enter power-saving mode based on the first timer and the second timer, specifically including:

[0105] Step S602: Send an attach request to the core network device. The attach request carries update requests for the first timer and the second timer.

[0106] Step S604: Receive the first update value of the first timer and the second update value of the second timer from the core network device based on the update request.

[0107] Step S606: Start the first timer and the second timer.

[0108] Step S608: When the first timer reaches the first update value, configure the first card to enter power saving mode; when the second timer reaches the second update value, configure the first card to exit power saving mode.

[0109] The first timer is T3324, and the second timer is T3412.

[0110] In this embodiment, when the first card enters an idle state and releases the RRC connection, timer T3324 is started. When T3324 terminates, it enters PSM mode and starts T3412 (periodic TAU update). During this period, the first card stops detecting paging and executing any cell / PLMN selection or MM procedure. By configuring the first timer and the second timer on the first card, the first card can achieve power saving while camped on the SA network, thereby ensuring the reliable execution of the VoLET voice service of the second card.

[0111] Those skilled in the art will understand that if there is no eligible NR cell that meets the network selection criteria, the terminal's first SIM card may negotiate with the network to configure the DRX long or short period to reduce the number of times the UE listens for paging, or update the timers T3324 and T3412 through Attch Req to improve the terminal's power consumption efficiency. At this time, although the first SIM card is still registered in the 5G network, in sleep or power-saving mode, the network cannot send data to the terminal or page the terminal, and the network and the terminal are almost disconnected. Only when the periodic TAU update timer expires will it exit PSM mode.

[0112] In one embodiment, the method further includes: when the second card is detected to have terminated its VoLTE voice service, sending a registration recovery request to the network device of the first card, wherein the registration recovery request is used to indicate that the first card's radio capability is to be able to camp on an SA network or an LTE network.

[0113] In this embodiment, when the second card is detected to have ended its VoLTE voice service, the first card needs to be restored to a state where it can switch between 4G and 5G networks. By sending a registration recovery request to the core network equipment, the core network equipment updates the UE Capability of the first card again, so that when the first card performs cell reselection again, it can not only camp on NR cells but also on LTE cells, thereby ensuring the reliable execution of various services of the first card.

[0114] like Figure 7 As shown, a dual-SIM terminal network scheduling method according to another embodiment of this disclosure includes:

[0115] Step S702: Receive the radio capability of the first SIM card of the dual-SIM terminal. The radio capability is used to indicate that when the second SIM card of the dual-SIM terminal performs Long Term Evolution (LTE) VoLET voice service, the first SIM card is camped on the SA network.

[0116] In this embodiment, by receiving the radio capability reported by the first SIM card when it detects that the second SIM card is in VoLET voice service mode, which allows it to continue to camp on the SA network, this prevents the second SIM card from preempting LTE network resources due to the first SIM card falling back to the LTE network, thus avoiding issues such as call reconstruction and dropped calls when the second SIM card is in VoLET voice service. This is beneficial to improving the stability of the dual-SIM dual-pass terminal when performing VoLET voice service and enhancing the user experience.

[0117] In one embodiment, receiving the wireless capability of the first SIM card in a dual-SIM terminal specifically includes:

[0118] The registration update request is received. The registration type of the registration update request is Mobility RegistrationUpdate. The registration update request carries the UE Radio Capability Update indication.

[0119] The UE Radio Capability Update instruction carried in the registration update request updates the stored radio capability of the first card to continue camping on the SA network. The UE Radio Capability Update instruction is also used to indicate that the first card can accept camping on NR cells.

[0120] In one embodiment, it further includes: disseminating the registered tracking area based on wireless capabilities.

[0121] In one embodiment, the method further includes: receiving an attach request sent by a dual-SIM terminal, the attach request carrying update requests for a first timer and a second timer; and feeding back a first update value for the first timer and a second update value for the second timer based on the update request.

[0122] In one embodiment, the method further includes: receiving a registration recovery request, the registration recovery request being used to indicate that the first card's wireless capability is to be able to camp on an SA network or an LTE network.

[0123] like Figure 8 As shown, a dual-SIM terminal network scheduling method according to another embodiment of this disclosure includes:

[0124] Step S802: The dual-SIM terminal begins operation.

[0125] In step S804, the first and second SIM cards of the dual-SIM terminal successfully register on their respective networks and enter dual-SIM dual-standby mode.

[0126] In step S806, the terminal determines whether the second SIM card is using VoLTE service. If not, it continues in dual SIM dual standby mode.

[0127] Step S808: If the second card is performing VoLTE service, the first card, which is in the RRC_IDLE or RRC_INACTIVE state, executes a Registration type of Mobility Registration Update Registration process.

[0128] The Registration message includes a UE Radio Capability Update indication.

[0129] In step S810, after receiving this Registration message, the AMF updates the NG-RAN radio capability and acceptable cells of the first card to SA mode, i.e., RAN-Type: NR.

[0130] In step S812, according to the cell reselection criteria, the terminal may perform cell reselection and attempt to camp on an available NR cell. In the RRC_INACTIVE state, if the new NR cell does not belong to the configured RNA, the RNA update process will be executed.

[0131] In step S814, the terminal determines whether the NR cell that can be camped meets the network selection conditions of the first card. If "yes", proceed to step S816; if "no", proceed to step S818.

[0132] In step S816, the first SIM card continues to be registered in the NR cell, while the second SIM card continues to use VoLTE service without being affected.

[0133] In step S818, the first SIM card negotiates the DRX long / short cycle configuration with the network to reduce the number of times the UE listens for paging, or updates timers T3324 and T3412 via Attch Req. When T3324 times out, the UE enters PSM; when T3412 times out, the UE exits PSM.

[0134] Based on the above solution, the first SIM card will not fall back to LTE, thus avoiding preemption of the LTE radio frequency resources currently used by the second SIM card's VoLTE service, and effectively ensuring the voice performance of the second SIM card.

[0135] In step S820, the terminal continues to monitor whether the second card is using VoLTE service. If so, the solution continues to be implemented.

[0136] Step S822: After the VoLTE service on the second SIM card ends, the terminal enters dual SIM dual standby mode.

[0137] In this embodiment, based on the aforementioned scheduling scheme for ensuring voice performance in dual-SIM terminals, the first SIM card negotiates with the network to update the UE Radio Capability Update indication to SAmode (RAN-Type): NR, based on the service status of the second SIM card, and continues to operate in an NR cell. If no NR cell meets the network selection criteria, the first SIM card negotiates with the network for DRX long / short cycle configuration to reduce the number of UE paging attempts; or updates timers T3324 and T3412 via Attch Req. This ensures that the first SIM card does not fall back to LTE, avoiding preemption of LTE radio frequency resources used by the second SIM card's VoLTE service, thus effectively guaranteeing the voice performance of the second SIM card.
