Description

Service indication method, terminal and network equipment

Technical Field

The invention relates to the technical field of mobile communication, in particular to a service indication method, a terminal and network equipment.

Background

In the prior art, a large number of multi-card terminals exist in a network, and the most common of the multi-card terminals is a dual-card terminal. Herein, the multi-card terminal is a terminal that includes at least 2 Subscriber Identity Module (SIM) cards, and communication systems of networks respectively accessed by the SIM cards may be the same, may be different, or may be partially the same and partially different. Here, the Communication System may specifically include a Global System for Mobile Communication (GSM), a Wideband Code Division Multiple Access (WCDMA), various Long Time Evolution (LTE)/LTE Evolution (LTE-Advanced, LTE-a) systems, a New Radio (NR) System, and the like.

In order to reduce the cost, many terminals only have a single-transmitting or single-receiving function, that is, the terminal can only have one SIM card in a connected state at most at a certain time. When an SIM-A card of User Equipment (UE) is in a connected state and an SIM-B card is in an idle/inactive (idle/inactive) state, if the SIM-B card has a service with higher priority such as voice, the UE usually should interrupt the service of the SIM-A and switch to the SIM-B card to receive the service; if the service priority reached by the SIM-B card is not higher than the current service priority of the SIM-A card, the UE can continue to work on the SIM-A card.

ON the other hand, the Wake Up Signal (WUS) is a new Physical Downlink Control Channel (PDCCH) format (format) for indicating whether a UE in a connected state and configured with Discontinuous Reception (DRX) needs to Wake Up to monitor the PDCCH at a Wake-Up (ON) time, and if no traffic arrives at the network side, the UE may Wake Up at an ON period without following an original DRX rule, thereby achieving the purpose of further saving power.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station and/or a core network element, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention only takes the Base Station in the NR system as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

As described in the background art, a large number of multi-card terminals exist in the current network, for example, a dual-card single-receiving/transmitting terminal, if the terminal is currently operating on the SIM-a card, it needs to periodically monitor the paging message of the SIM-B card to determine whether a higher priority service arrives on the SIM-B. In order to notify the terminal of the service condition of the SIM-B card, a possible technical solution is to indicate the type or priority of the service in a Paging message sent to the SIM-B card, such as a Voice over Long-Term Evolution (VoLTE) or a new air interface (Voice over NR, VoNR) service, and then the terminal needs to monitor a PDCCH to see whether there is a Paging message scrambled by a Paging Radio Network Temporary Identifier (P-RNTI), and then parse the Paging message to determine whether the type or priority of the service is indicated. If the service priority carried in the paging message is lower, the terminal does not need to switch to the SIM-B card to receive the service.

The embodiment of the invention provides a service indication method, which can directly indicate the type or priority of the service in the wake-up signal, so that a terminal can judge whether the terminal needs to be converted to an SIM-B to receive the service by only solving the wake-up signal without further monitoring a PDCCH and solving a paging message, thereby further saving the power consumption of the terminal.

In order to solve at least one of the above problems, embodiments of the present invention provide a service indication method, which can save power consumption of a terminal. Referring to fig. 2, a service indication method provided in an embodiment of the present invention, when applied to a first terminal that supports at least a first SIM card and a second SIM card, includes:

step 21, receiving a wake-up signal sent by a first network where a first SIM card resides at the first terminal where the first SIM card performs a first service, where the wake-up signal carries service indication information of a second service that arrives at a second SIM card, where the second SIM card is in an idle state or an inactive state.

Here, the first terminal is a multi-card terminal and can support at least two SIM cards, such as a first SIM card and a second SIM card. Here, the first SIM card and the second SIM card may correspond to networks of the same operator (including networks of different communication systems and networks of the same communication system).

It is assumed that a first terminal performs a first service on a first SIM card, that is, the first SIM card is in a connected state in a corresponding first network (the first terminal registers to the corresponding first network based on the first SIM card, and a current state of the first terminal in the network is a connected state), and a second SIM card is in an idle state or an inactive state in a corresponding second network (the first terminal registers to the corresponding second network based on the second SIM card, and a state of the first terminal in the network is an idle state or an inactive state, and the first network and the second network may be the same or different). At this time, the first terminal obtains the service information arriving on the second SIM card by receiving the wake-up signal sent by the network corresponding to the first SIM card. When the first SIM card and the second SIM card correspond to the same or different networks of the same operator, the network side may determine that the first SIM card and the second SIM card are two SIM cards of the same terminal according to the registration information of the terminal, so that the network device may associate the services of the first SIM card in the connected state and the second SIM card in the idle state/inactive state, and send service indication information for indicating the second service to the first SIM card when the service of the second SIM card arrives. Specifically, the service indication information may be service type and/or priority information of the second service.

Through the steps, when the first terminal performs the service on the first SIM card, the service information of the other SIM cards can be acquired without switching to the other SIM cards, so that the service indication among the SIM cards is realized. The subsequent first terminal can determine whether to switch to other SIM cards for response according to the arriving service information, thereby providing support for further reducing the power consumption of the multi-card terminal subsequently.

For example, after the step 21, the method of the embodiment of the present invention may further include the steps of: and the first terminal judges whether to switch to a second SIM card for carrying out the second service.

Here, the first terminal may determine whether to switch to the second SIM card for the second service according to the service indication information.

For example, the first terminal may determine the priority of the second service according to the service indication information, and compare the priorities of the first service and the second service.

Then, when the priority of the first service is not lower than or higher than the priority of the second service, continuing to perform the first service through the first SIM card; and/or when the priority of the first service is lower or not higher than that of the second service, switching to the second SIM card to carry out the second service. That is to say:

when the priority of the first service is not lower than that of the second service, the first service is continuously carried out through the first SIM card, and the first service is not converted into the second SIM card at the moment; when the priority of the first service is lower than that of the second service, switching to the second SIM card to carry out the second service;

or when the priority of the first service is higher than that of the second service, continuing to perform the first service through the first SIM card, and not switching to the second SIM card at the moment; and when the priority of the first service is not higher than that of the second service, switching to the second SIM card to carry out the second service.

Through the steps, the embodiment of the invention realizes that the terminal can directly determine whether to switch to the second SIM card for service according to the wake-up signal received by the first SIM card under the condition that the first SIM card is in a connected state and the second SIM card is in an idle state/non-activated state, and does not need to monitor the PDCCH and analyze the paging message on the second SIM card to determine whether to perform service on the second SIM card, thereby avoiding unnecessary conversion processing among the SIM cards and saving the power consumption and the calculation expense generated by monitoring the PDCCH and analyzing the paging message.

According to at least one embodiment of the present invention, in the process of comparing the priorities of the first service and the second service in step 22, the first terminal may obtain a comparison result that the priority of the first service is not lower than or higher than the priority of the second service in the case that the second service is a preset low-priority service;

In addition, the service indication information may be carried by a preset downlink control information DCI scrambled by a Power Saving Radio Network Temporary Identifier (PS-RNTI). As an implementation manner, the service indication information may be carried in a preset domain in the preset DCI, where a value of the preset domain corresponds to a priority of the second service or corresponds to a service type of the second service. For example, different values of the preset field are used to indicate different priorities, or are used to indicate different service types, each service type having a respective priority.

Referring to fig. 3, a flow of the service indication method when applied to a network device is provided, including:

step 31, the network device detects that a second service of the first terminal arrives on the second SIM card, where the first SIM card of the first terminal is in a connected state, and the second SIM card is in an idle state or an inactive state.

Here, the first SIM card and the second SIM card may reside in a network of the same communication system or different communication systems operated by the same operator. In step 31, the network device may be a device in a network corresponding to the first SIM card, such as a first base station. When the first SIM card resides in a first network of a certain operator and the second SIM card resides in a second network of the same operator (assuming that the first network and the second network are different), the first base station may obtain information of a second service sent to the second SIM card by the second network through the inter-network interface. And when the first SIM card and the second SIM card both reside in the same network of the same operator, the first base station may directly obtain the service information that arrives on the second SIM card from the network. Of course, different networks may also provide services for the terminal in the form of a public base station, and at this time, the public base station may be respectively accessed to core networks of different networks, so that information of services sent by each network to each SIM card of the terminal may be conveniently obtained.

Step 32, the network device sends a wake-up signal to the first terminal in the first network where the first SIM card resides, where the wake-up signal carries the service indication information of the second service.

Here, the service indication information is service type or priority information of the second service. Similarly, the service indication information may be carried by a preset DCI scrambled by a PS-RNTI, for example, the service indication information is carried in a preset domain in the preset DCI, where a value of the preset domain corresponds to a priority of the second service or corresponds to a service type of the second service.

Through the steps, the embodiment of the invention realizes that the indication information of the service arriving on other SIM cards of the first terminal is sent to the first SIM card under the condition that the first SIM card of the first terminal is in a connected state, so that when the first terminal carries out the service on the first SIM card, the service information arriving on other SIM cards can be obtained without switching to other SIM cards, and the service indication between the SIM cards is realized. The subsequent terminal can determine whether to switch to other SIM cards for response according to the arrived service information, so that the subsequent terminal does not need to switch to other SIM cards to detect and analyze the PDCCH and the paging message, thereby avoiding unnecessary switching processing between the SIM cards and saving the power consumption of the terminal.

To facilitate a better understanding of the above method embodiments, a more specific example of the above method embodiments is provided below.

Example 1:

in this example 1, it is assumed that a certain UE includes two SIM cards, SIM-a and SIM-B, respectively, and that the two SIM cards belong to the same operator.

S101, a network side (such as a base station) carries service type or priority information reaching an SIM-B in a WUS message sent to the SIM-A in a connection state of the UE. Specifically, this information may be carried in DCI format2_6 for WUS:

DCI format2_6 scrambled by PS-RNTI includes the following fields:

block numbers, such as block number 1, block number 2, …, block number N, each block (block) corresponding to one or a group of UEs;

the fields (fields) of each block include:

-Wake-up indication (Wake-up indication), 1 bit;

-indication information (SCell downlink indication) related to carrier aggregation

The type or priority indication information of the service, for example, 1 bit is used to indicate whether a high priority service such as VoLTE or VoNR arrives, and the bit position 1 indicates that the high priority service such as VoLTE or VoNR arrives; if the bit position 0 or the bit position is null, it indicates that no high-priority service such as VoLTE or VoNR arrives or the service priority of the arriving service is general or not high; for another example, the service type of the arrival is identified by a plurality of bits, for example, two bits represent a voice service when the value 00 is taken, and the value 01 represents an internet service and the like.

S102, after receiving the WUS message, the terminal judges whether to switch to the SIM-B to receive the service according to the service type or priority indication information of the SIM-B carried in the WUS message:

1) when the WUS message indicates that high-priority services such as VoLTE or VoNR arrive on the SIM-B:

if the current UE carries out daA service with common priority on the SIM-A, the UE can be converted to the SIM-B to receive high-priority service such as VoLTE or VoNR;

if the current UE carries out high-priority services such as VoLTE or VoNR on the SIM-A, the UE can continue to work on the SIM-A.

2) If the WUS message indicates that no high-priority service such as VoLTE or VoNR arrives on the SIM-B, or the priority of the arriving service is general or low, the UE can continue to work on the SIM-A.

In some embodiments of the invention, there is also provided a computer readable storage medium having a program stored thereon, which when executed by a processor, performs the steps of:

When being executed by the processor, the program can realize all the implementation manners in the service indication method applied to the network equipment, and can achieve the same technical effect, and the details are not repeated here in order to avoid repetition.

It is considered that in some cases, there is a certain difficulty in the interaction of the service state information between different SIM cards of the terminal. For example, when two SIM cards belong to different operators, an interface for information interaction may need to be established in advance between network devices of the different operators.

In order to reduce the impact of different situations on the implementation of the embodiment of the present invention, other embodiments of the present invention further provide another service indication method, which may also be applied to a first terminal that supports at least a first SIM card and a second SIM card, where the first SIM card and the second SIM card may reside in networks of the same communication system or different communication systems of the same operator, or may reside in networks of different operators. As shown in fig. 8, the method includes:

step 81, the first terminal performing the first service on the first SIM card detects a wake-up signal sent by the second network where the second SIM card resides, where the wake-up signal carries service indication information of the second service, and the second SIM card is in an idle state or an inactive state.

Through the steps, when the first terminal performs the service in the first network corresponding to the first SIM card, the wake-up signal sent by the second network corresponding to the second SIM card can be detected, so that the indication of the service arrival between different SIM cards is realized, and support is provided for the subsequent terminal to decide whether to switch to the second SIM card for further detection.

In order to reduce the number of the wake-up signals, in step 81, the first terminal may detect the wake-up signal according to a wake-up signal detection timing grouped by the first terminal to which the first terminal belongs, where the wake-up signal detection timing is a predetermined timing, and specifically includes at least one of the following:

1) the wake-up time in the DRX cycle corresponding to the second SIM card, namely the DRX ON period in the DRX cycle;

2) a first preset time before DRX ON of a DRX cycle, where the first preset time may be a preset length of time;

3) a second predetermined time before the Paging Opportunity (PO), where the second predetermined time may be a time period of a predetermined length, and the second predetermined time may be the same as or different from the first predetermined time.

In step 81, the first terminal detects a wake-up signal in the second network where the second SIM card resides according to the wake-up signal detection time, where the wake-up signal carries indication information of a service where the first terminal packet arrives, for example, after a certain terminal (which may be the first terminal or another terminal) in the first terminal packet arrives at a certain service, the second network sends a wake-up signal at the wake-up signal detection time, and a terminal in a dormant state in the first terminal packet wakes up at the wake-up signal detection time to detect the wake-up signal.

Here, the first terminal group to which the first terminal belongs is obtained by grouping according to a preset grouping manner. For example, the operation may be performed according to an International Mobile Subscriber Identity (IMSI) or a Temporary Mobile Subscription Identifier (TMSI) or S-TMSI of the second SIM card of the terminal, such as mod 1024 operation, and terminals with the same remainder are grouped into the same group. The grouping can be performed in the same manner as the grouping of the received paging message. Optionally, the grouping manner may be predefined or specified by the operator.

According to other embodiments of the present invention, after step 81, the method of an embodiment of the present invention may further include the steps of: the first determination is made whether to detect a paging message sent by the second network to a second SIM card.

Here, the first terminal determines whether to detect the paging message sent by the second network to the second SIM card according to the detection result of the wake-up signal. In particular, the method comprises the following steps of,

1) in case the detection result of the wake-up signal indicates that the wake-up signal is not detected

At this time, the first terminal may determine whether to detect the paging message sent by the second network to the second SIM card according to the priority of the first service. For example, when the first service is a preset high-priority service, the terminal may not detect a paging message sent by the second network to the second SIM card; and/or when the first service is a preset low-priority service, the terminal detects a paging message sent by the second network to the second SIM card. Through the above manner, the embodiment of the invention can avoid the terminal from detecting the paging message on the second SIM card when the first service is the preset high-priority service, thereby saving the power consumption and the calculation overhead generated by the terminal in detecting the paging message on the PDCCH and the PDSCH.

2) In case the detection result of the wake-up signal indicates that the wake-up signal is detected

Here, the service indication information may specifically include service type and/or priority information of the second service. At this time, the first terminal may determine the priority of the second service according to the service indication information, and compare the priorities of the first service and the second service.

For example, when the priority of the first service is not lower than the priority of the second service, the paging message sent to the second SIM card by the second network is not detected; and/or detecting the paging message sent to the second SIM card by the second network when the priority of the first service is lower than that of the second service.

For another example, when the priority of the first service is higher than that of the second service, the paging message sent by the second network to the second SIM card is not detected; and/or when the priority of the first service is not higher than that of the second service, detecting the paging message sent to the second SIM card by the second network.

Through the above manner, the embodiment of the invention can avoid the terminal from detecting the paging message on the second SIM card when the priority of the second service does not meet the preset condition, thereby saving the power consumption and the calculation overhead generated by the terminal in detecting the paging message on the PDCCH and the PDSCH and ensuring the reliability of the high-priority service.

Through the steps, the embodiment of the invention can reduce the power consumption and the calculation overhead generated by detecting unnecessary paging messages by the terminal and ensure the reliability of high-priority services.

According to at least one embodiment of the present invention, in step 82, after determining to detect the paging message sent by the second network to the second SIM card, the first terminal may further detect the paging message sent by the second network to the second SIM card on a Paging Opportunity (PO) of the second SIM card, specifically including detecting the paging message on the PDCCH and confirming whether the paging message is the paging message sent to the terminal by detecting the PDSCH.

In this embodiment of the present invention, the service indication information is service type or priority information of the second service. Several forms of wake-up signals that may be employed by embodiments of the present invention are provided below:

1) the wake-up signal is preset DCI scrambled by preset RNTI.

Here, the preset RNTI may be a type of RNTI agreed in advance or defined in advance. For example, a DCI format (e.g., format2_ X, where X represents a number) and a new RNTI, i.e., a non-connected power saving radio network temporary identity (iPS-RNTI) as described herein, may be predefined. In this way, the service indication information may be carried in a preset domain in a preset DCI scrambled by a preset iPS-RNTI, where a value of the preset domain corresponds to a priority of the second service or corresponds to a service type of the second service.

2) The wake-up signal is a preset physical layer sequence.

Embodiments of the present invention may define a set of algorithms for computing physical layer sequences (sequences), where one or a group of terminals has a set of corresponding physical layer sequences, e.g., different terminal groups correspond to different physical layer sequences, and/or different service types or service priorities correspond to different physical layer sequences in the same terminal group. The transmission timing of the physical layer sequence may coincide with a Paging Opportunity (PO). Thus, when the terminal detects the corresponding physical layer sequence, it can be determined that the wake-up signal is detected, which indicates that the packet to which the terminal belongs reaches the new service.

Referring to fig. 9, a flow of the service indication method when applied to a network device in a second network where a second SIM card of a first terminal resides is provided, as shown in fig. 9, the method includes:

step 91, detecting that a second service of the first terminal arrives on a second SIM card, wherein the second SIM card is in an idle state or an inactive state.

Here, the first terminal may be a multi-card terminal supporting at least a first SIM card and a second SIM card. The first terminal group to which the first terminal belongs may be obtained by grouping according to a preset grouping manner.

And step 92, sending a wake-up signal to the first terminal, where the wake-up signal carries the service indication information of the second service.

Here, the service indication information is service type or priority information of the second service. The network device may send the wake-up signal according to a wake-up signal sending occasion of a first terminal group to which the first terminal belongs, where the wake-up signal sending occasion includes at least one of: a wake-up time in a Discontinuous Reception (DRX) cycle corresponding to the second SIM card; a first preset time before DRX ON of a DRX period; a second preset time before a Paging Opportunity (PO).

Through the above steps, the network device in the embodiment of the present invention sends the wake-up signal at the wake-up signal sending time, so that the terminal performing a service on another SIM card can determine whether to detect the paging message on the second SIM card according to the wake-up signal, thereby avoiding power consumption and calculation overhead caused by the terminal detecting an unnecessary paging message, and ensuring reliability of a high-priority service.

As described above, the wake-up signal may be a preset DCI scrambled by a preset RNTI or a preset physical layer sequence. Under the condition that the wake-up signal is preset DCI scrambled by a preset RNTI, the service indication information is carried in a preset domain in the preset DCI scrambled by a PS-RNTI, wherein the value of the preset domain corresponds to the priority of the second service or the service type of the second service; and under the condition that the wake-up signal is a preset physical layer sequence, different terminal groups correspond to different physical layer sequences, and/or different service types or service priorities correspond to different physical layer sequences in the same terminal group.

After the above step 92, the network device may also send a paging message for the first terminal on a paging opportunity of the first terminal in the second network.

To assist in a better understanding of the above method embodiments, the following further describes the above embodiments by way of a more specific example.

Example 2:

in this example 2, it is assumed that a certain UE includes two SIM cards, SIM-a and SIM-B, which belong to different operators respectively.

S201, grouping the terminals according to a certain scheme, for example, carrying out mod 1024 operation on IMSI, TMSI or S-TMSI of the UE, and grouping the terminals with the same remainder into the same group. Alternatively, the terminals are grouped in a manner consistent with the grouping manner of the received paging message. The grouping method is predefined or specified by the operator.

S202, defining a new iWUS mechanism suitable for idle and/or inactive states, such as

1) By means of the DCI format, a set of DCI format (such as format2_ x) and iWUS RNTI (such as iPS-RNTI) is defined. The DCI format2_ x is scrambled by using an iPS-RNTI (Cyclic Redundancy Check, CRC), and the content comprises the following steps:

-service type or priority indication information, such as 1 bit indicating whether a high priority service such as VoLTE or VoNR arrives, where bit position 1 indicates that a high priority service such as VoLTE or VoNR arrives, and bit position 0 or null indicates that no high priority service such as VoLTE or VoNR arrives or arrives at a normal or low priority service; or a plurality of bits are used for identifying the type of the arriving service, for example, two bits are adopted, wherein 00 represents voice service, 01 represents internet service, and the like.

2) A set of mechanism for calculating sequence is predefined by means of physical layer sequence code (sequence), one or a group of UE has a set of corresponding sequence, and the sending time of the sequence can be consistent with the Paging Opportunity (PO).

When the UE detects the corresponding sequence, the UE can think that the high-priority service sent to the group of UE arrives; further, different sequences can be defined for different services, for example, sequence X represents a voice service, sequence Y represents an internet access service, and the like.

And S303, when the SIM-B works in idle or inactive UE, the UE wakes up every DRX period or a period before DRX ON arrives (such as N ms, N TTIs and the like, which can be predefined or configured by a network side through a broadcast message) or a period before PO, using an iPS-RNTI to detect common (common PDCCH) or detect sequence so as to judge whether the network side sends iWUS aiming at the UE of the group.

1) If the UE does not detect the iWUS indication information, the UE indicates that no high-priority service arrives in the group of UEs, and the UE can judge whether the paging message needs to be further detected according to the service priority condition of another SIM-A.

For example, if SIM-a is currently operating in high priority voice service, the UE may not detect further paging messages on the SIM-B PDSCH because the UE should not switch to SIM-B for the service even if there is traffic on SIM-B, which is of lower or no higher priority than SIM-a. In this way, the overhead of detecting the paging message on the PDSCH of the UE can be saved, and the power consumption and the calculation overhead of the UE can be saved.

2) If the UE resolves the iWUS indication information and indicates that the high-priority service arrives in the UE of the group, the UE further detects the paging message to see whether the high-priority service of the UE arrives. If so, the UE can be switched to the SIM-B to carry out the service; if no high-priority service of the UE arrives, the UE can continue to work on the SIM-A in the current connection state, so that the expense of detecting the paging message on the PDSCH of the UE can be saved, and the power consumption and the calculation expense of the UE can be saved.
