Hereinafter, each step of the dual card terminal network scheduling method in the present exemplary embodiment will be described in more detail with reference to the accompanying drawings and examples.

The dual card terminal network scheduling scheme according to one embodiment of the present disclosure is applicable to, but not limited to, dual card terminals. As shown in fig. 1, a system for performing network scheduling of a dual card terminal includes:

a dual card terminal 102, the dual card terminal comprising a first card SIM1 and a second card SIM2, wherein the first card supports an SA network and an LTE network, and the second card supports the LTE network.

The second card accesses the core network device 108 through the access network device eNB, and the first card accesses the core network device 108 through the access network device gNB106, where the core network device 108 may be an AMF or an MME.

As shown in fig. 2, a dual card terminal network scheduling method according to an embodiment of the present disclosure is applied to a terminal, where the dual card terminal is loaded with a first card and a second card, the first card can reside in an SA network or an LTE network, and the second card resides in the LTE network, and includes:

Step S202, when it is detected that the second card executes the long term evolution voice VoLET voice service, the first card is in rrc_idle state or rrc_inactive state, and the wireless capability corresponding to the voice service is reported to the network device of the first card, where the wireless capability is used to indicate that the first card resides in the SA network when the second card executes the VoLET voice service.

Specifically, the first card is denoted as a primary card, and the second card is denoted as a secondary card.

In addition, in the rrc_idle state, services provided to the UE by the network include limited services, normal services, operator services, and the like; in the rrc_inactive state, services provided to the UE by the network include normal services, operator services, and the like.

In this embodiment, when the service state of the first card detects that the service state of the second card is a VoLET voice service state, the wireless capability of only residing in the SA network is reported to continue to reside in the SA network, so that the problems of rebuilding, dropped call and the like of the second card when the second card is in the VoLET voice service due to falling back to the LTE network and preempting the LTE network resource of the second card are prevented for the dual-card terminal only supporting the sa+lte mode, thereby being beneficial to improving the stability of the dual-card dual-pass terminal when the VoLET voice service is executed and improving the use experience of a user.

In one embodiment, the network device of the first card includes an access network device of the first card, specifically a gNB, and a core network device, which may be an AMF or MME.

As shown in fig. 3, in step S202, a specific implementation manner of reporting, to a network device of a first card, wireless capability corresponding to a voice service of the first card includes:

in step S302, a registration update request is sent to the network device, where the registration type of the registration update request is Mobility Registration Update, the registration update request carries UE Radio Capability Update indication, UE Radio Capability Update indication indicates that the network device updates the stored wireless capability of the first card to continue to camp on the SA network, and UE Radio Capability Update indication indicates that the camping cell acceptable to the first card is an NR cell.

The wireless Capability refers to Capability of the UE, that is, capability of the UE, the access network device makes correct scheduling for the UE after acquiring the Capability of the UE, if the UE supports a certain function, the base station may configure the function for the UE, if the UE does not support a certain function, the base station may not configure the function for the UE, and by reporting to the access network device and the core network device that the first card can only reside in the SA network, the first card performs cell reselection operation only based on the UR cell.

UE Capability mainly involves two flows: the method comprises the steps that a UE Capability request and UE Capability report are carried out, when the access network equipment needs the UE to report the UE Capability, the access network equipment can send a UE Capability requirement instruction to the UE, and when the UE receives the UE Capability requirement instruction, the UE reports the UE Capability UE Capability Information according to the instruction.

Step S304, a cell reselection operation of the first card is performed, so that the first card continues to reside in the SA network.

Specifically, when the terminal is started, an initial registration operation is performed, at this time, the terminal reports to the network device the RAT (Radio Access Technology ) related capability of the first card, the associated terminal identifier, the information of the second card, and the like UE Assistance Information, when the first card in the 5G SA data service state receives the network side VoLTE MT call, before Trigger for Fallback and optional measurement report solicitation, the base station does not perform HandOver base station transfer or Redirect to the first card, prevents the first card from falling back to 4G, triggers an optimized scheduling procedure, and simultaneously identifies the identity of the same terminal associated with the two cards in UE Assistance Information reported by the search terminal such as an AMF network element, identifies the second card user associated with the first card as the same terminal, and sends the SIP Invite paging message of the VoLTE call after verification, and establishes IMS VoLTE Session Setup.

In addition, the terminal and network negotiation update UE Radio Capability Update is indicated as: SA mode, RAN-Type: NR, continuing to camp on NR cell.

Based on the registration update request, the UE sends AN message to the access network device, where the AN message includes AN message and Registration Request, and Registration request includes Registration type, SUCI or GUTI or PEI, and information such as TAI and security parameters accessed last time

Wherein Registration type represents the type of registration, including Initial Registration, mobility Registration Update, periodic Registration Update, and Emergency Registration.

Wherein Initial Registration is typically performed at power-on, in the scheme of the present disclosure, when the second card is detected to perform VoLET voice service, the first card performs a registration type Mobility Registration Update.

In this embodiment, when the second card is detected to be in the VoLET voice service execution state, a registration update request is sent to the core network device through the access network device, where the registration update request carries the wireless capability of the first card under the current working condition, that is, only the NR cell is resided, so that after the core network receives the registration update request, the TAI LIST is updated, where the TAI LIST only includes the NR cell, so that when the first card executes the cell reselection operation, only the NR cell can be resided, thereby preventing the first card from falling back to the 4G network, on one hand, avoiding preempting the LTE radio frequency resource that is being used by the VoLET voice service of the second card, improving the reliability of the voice call of the second card, and on the other hand, effectively guaranteeing the 5G NR data service performance of the first card, and further guaranteeing the excellent dual-pass performance of the dual-card terminal.

As shown in fig. 4, in one embodiment, further includes:

step S402, receiving a registered tracking area issued by the access network device based on the wireless capability.

The cell reselection operation is executed based on the first card, and specifically comprises the following steps:

step S404, according to the cell reselection criterion, cell reselection is performed, and the resident NR cell is determined.

Wherein the NR cell is a 5G network cell.

In step S406, it is detected whether the campeable NR cell belongs to a registered tracking area.

Step S408, when the campeable NR cell belongs to the registered tracking area, camping on the campeable NR cell based on the first card.

In step S410, when the campeable NR cell does not belong to the registered tracking area, a location update request is sent to the core network device through the access network device for the rrc_idle state, and an RNA update procedure is performed based on the campeable NR cell for the rrc_inactive state.

Specifically, when the first card cannot camp on the current cell based on the VoLET voice traffic state of the second card, a cell reselection operation needs to be performed, and the UE performs cell reselection according to a cell reselection criterion and attempts to camp on a new cell. If the new cell does not belong to the registered tracking area, the location update procedure is performed again. In the rrc_inactive state, if the new cell does not belong to the configured RNA, an RNA update procedure is performed.

In the rrc_idle and rrc_inactive states, the UE camping cell has mainly four aspects: (1) the UE may receive a system message under the current PLMN; (2) When registering and the UE wish to establish an RRC connection or resume a suspended RRC connection, the UE may initiate initial access on a camped cell control channel; (3) If the network needs to send a message or transmit data to a registered UE, the network in most cases knows the tracking area (in rrc_idle state) or RNA (in rrc_inactive state) where the UE resides, the network can send a paging message to the UE, the UE can receive the paging message, and respond; (4) the UE may receive ETWS and CMAS notifications;

in this embodiment, when a campeable NR cell is detected based on a cell reselection criterion, it is further detected whether the campeable NR cell belongs to a registered tracking area, so that the camping of the NR cell is performed only with the detection result, thereby enabling to ensure that the first card does not fall back to the 4G network.

As shown in fig. 5, the cell reselection operation is performed based on the first card, specifically including:

step S502, according to the cell reselection criterion, cell reselection is performed, and the resident NR cell is determined.

Step S504, it is detected whether the resident NR cell belongs to a registered tracking area.

Step S506, when the campeable NR cell belongs to the registered tracking area, camping on the campeable NR cell based on the first card.

Step S508, when the campeable NR cell does not belong to the registered tracking area, for the rrc_idle state, a location update request is sent to the core network device through the access network device, and for the rrc_inactive state, an RNA update procedure is performed based on the campeable NR cell.

Step S510, measures the signal strength RSRP of the campeable NR cell.

Step S512, it is detected whether the network selection condition of the first card is satisfied by the resident NR cell based on RSRP.

Step S514, when the campeable NR cell satisfies the network selection condition, continuing to camp on the campeable NR cell based on the first card.

In this embodiment, when a campeable NR cell is detected, the signal strength RSRP of the campeable NR cell is further measured to detect whether the current network environment satisfies the network selection condition of the first card based on the signal strength RSRP, so that when satisfied, a new NR cell is camped, and when not satisfied, the current NR cell is continued to be camped, but the operation state is configured.

In one embodiment, further comprising:

in step S516, when the resident NR cell does not meet the network selection condition, the first card is configured to operate based on the discontinuous reception DRX mechanism.

Specifically, after the UE completes camping in the current NR cell, the UE may be said to enter an "IDLE state" or an "IDLE state", if the UE subsequently completes a random access procedure, the UE may be said to enter a "CONNECTED state" or a "CONNECTED state", and no matter in the IDLE state or the CONNECTED state, by setting a DRX mechanism, it is possible to ensure that the UE saves power on the premise of effective transmission of data.

One DRX cycle is equal to the sum of the wake-up time (ON-duration) and the sleep time of the UE, and the system may configure the UE with a short cycle (short DRX cycle) or a long cycle (long DRX cycle) according to different traffic scenarios, respectively. For example, when VOIP is performed, a voice codec typically transmits a VOIP packet for 20ms, a DRX short cycle with a length of 20ms can be configured, and a longer silence period during a voice call can be configured. If both the short and long periods are configured and the drxShortCycleTimer timer times out, the UE will enter a long DRX cycle.

In this embodiment, by configuring the DRX mechanism for the first card, the first card is enabled to implement a power saving function while residing in the SA network, thereby ensuring reliable execution of the VoLET voice service of the second card.

In one embodiment, further comprising:

in step S518, when the resident NR cell does not meet the network selection condition, the first card is controlled to enter the power saving mode based on the first timer and the second timer.

Specifically, as shown in fig. 6, the first card is controlled to enter the power saving mode based on the first timer and the second timer, specifically including:

step S602, an attach request is sent to the core network device, where the attach request carries update requests of the first timer and the second timer.

In step S604, the receiving core network device feeds back a first updated value of the first timer and a second updated value of the second timer based on the update request.

Step S606, the first timer and the second timer are started.

In step S608, the first card is configured to enter the power saving mode when the first timer reaches the first update value, and the first card is configured to exit the power saving mode when the second timer reaches the second update value.

Wherein the first timer is T3324, and the second timer is T3412.

In this embodiment, after the first card enters the idle state and releases the RRC connection, the timer T3324 is started, after the T3324 is terminated, the PSM mode is entered, and the T3412 (periodic TAU update) is started, during which the first card stops detecting paging and executing any cell/PLMN selection or MM procedure, and by configuring the first timer and the second timer for the first card, the first card realizes the power saving function while residing in the SA network, thereby ensuring reliable execution of the VoLET voice service of the second card.

It can be understood by those skilled in the art that if the network selection condition is not satisfied and the resident NR cell is not satisfied, the first card of the terminal negotiates the DRX long and short period configuration with the network, reduces the number of times the UE listens to Paging, or improves the power consumption efficiency of the terminal by means of the Attch Req update timers T3324 and T3412, at this time, although the first card is still registered in the 5G network, the network cannot send data to the terminal or Paging terminal in the sleep state or the power saving state, the network is almost in communication with the terminal, and exits the PSM mode only after the periodic TAU update timer times out.

In this embodiment, when the second card is detected to end the VoLET voice service, the first card needs to restore the state that can be switched between the 4G and 5G networks, and a registration restoration request is sent to the core network device, so that the core network device updates the UE Capability of the first card again, and when the first card reselects a cell again, not only an NR cell but also an LTE cell can be resided, so as to ensure reliable execution of multiple services of the first card.

As shown in fig. 7, a dual card terminal network scheduling method according to another embodiment of the present disclosure includes:

in step S702, the wireless capability of the first card of the dual-card terminal is received, where the wireless capability is used to indicate that the first card resides in the SA network when the second card of the dual-card terminal performs the long term evolution voice VoLET voice service.

In this embodiment, when the service state of the first card is detected to be the VoLET voice service state, the wireless capability of the SA network which can only be resided is reported so as to continue to reside in the SA network, so that the problems of rebuilding, dropped call and the like of the second card when the second card is in the VoLET voice service due to the fact that the first card falls back to the LTE network and the LTE network resource of the second card is preempted are prevented for the dual-card terminal which only supports the sa+lte mode, and further stability of the dual-card dual-pass terminal when the VoLET voice service is executed is facilitated, and use experience of a user is improved.

In one embodiment, the wireless capability of the first card of the dual card terminal is received, specifically including:

a registration update request is received, the registration type of the registration update request being Mobility Registration Update, the registration update request carrying UE Radio Capability Update indications.

UE Radio Capability Update carried on the registration update request indicates that the stored wireless capability of the first card is updated to continue to camp on the SA network, UE Radio Capability Update indicates that the camping cell acceptable to the first card is also indicated as an NR cell.

In one embodiment, further comprising: the registered tracking areas are issued based on the wireless capability.

In one embodiment, further comprising: receiving an attach request sent by a double-card terminal, wherein the attach request carries update requests of a first timer and a second timer; the first updated value of the first timer and the second updated value of the second timer are fed back based on the update request.

In one embodiment, further comprising: a registration restoration request is received, the registration restoration request indicating that the wireless capability of the first card is capable of camping on an SA network or an LTE network.

As shown in fig. 8, a dual card terminal network scheduling method according to still another embodiment of the present disclosure includes:

in step S802, the dual card terminal starts to operate.

Step S804, the first card and the second card of the dual-card terminal successfully reside in the respective networks and enter a dual-card dual-standby state.

Step S806, the terminal judges whether the second card performs VoLTE service, if not, the terminal continues to be in a double-card double-standby state.

In step S808, if the second card is performing VoLTE service, the first card in rrc_idle or rrc_inactive state performs a Registration type to Mobility Registration Update Registration flow.

Wherein a UE Radio Capability Update indication is included in the Registration message.

Step S810, after the AMF receives the Registration message, the AMF updates the NG-RAN radio capability and acceptable cells of the first card as: SA mode, RAN-Type: NR.

In step S812, the terminal performs cell reselection according to the cell reselection criteria, and tries to camp on the campeable NR cell, and in rrc_inactive state, if the new NR cell does not belong to the configured RNA, an RNA update procedure is performed.

In step S814, the terminal determines whether the resided NR cell satisfies the first network selection condition, if yes, it proceeds to step S816, and if no, it proceeds to step S818.

In step S816, the first card continues to reside in the NR cell, and the second card continues to perform VoLTE service without being affected.

In step S818, the first card negotiates the DRX long and short cycle configuration with the network, reducing the number of times the UE listens to Paging, or updates the timers T3324, T3412 by the atch Req. T3324 times out and UE enters PSM; t3412 times out and the UE exits PSM.

Based on the scheme, the first card does not fall back to LTE, so that the occupation of LTE radio frequency resources used by VoLTE service of the second card is avoided, and the voice performance of the second card is effectively ensured.

In step S820, the terminal continues to monitor whether the second card is performing VoLTE service, and if so, continues to implement the scheme.

Step S822, when the second card VoLTE service is finished, the terminal enters dual-card dual-standby.

In this embodiment, based on the above scheduling scheme suitable for the dual-card terminal to guarantee voice performance, the first card of the terminal negotiates with the network according to the service state of the second card to update UE Radio Capability Update as follows: SA mode, RAN-Type: NR, continuing to reside in NR cell; if the NR cell does not meet the network selection condition, the terminal first card negotiates with the network for DRX long and short period configuration, and the monitoring frequency of the UE is reduced; or by means of the Attch Req update timers T3324, T3412. Therefore, the first card is ensured not to fall back to LTE, the occupation of LTE radio frequency resources which are being used by VoLTE service of the second card is avoided, and the voice performance of the second card is effectively ensured.
