Referring to FIG. 1 , FIG. 1 shows 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 .

It should be noted that the specific type of 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 above-mentioned base station may be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or other access point, etc.), where a base station may be referred to as Node B, eNode B, access point, Base Transceiver Station (Base Transceiver Station, BTS), radio base station, radio transceiver, basic Service Set (Basic Service Set, BSS), Extended Service Set (Extended Service Set, ESS), Node B, Evolved Node B (eNB), Home Node B, Home Evolved Node B, WLAN access point, WiFi node or all 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 the base station in the NR system is used as an example, but it does not Specific types of base stations are defined.

The base stations may communicate with terminals 11 under the control of a base station controller, which may be part of a core network or certain base stations in various examples. Some base stations can communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via a backhaul link, which may be a wired or wireless communication link. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter is capable of transmitting 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 sent on a different carrier and may carry control information (eg, reference signal, control channel, etc.), overhead information, data, etc.

UL transmissions can also be called reverse link transmissions, and DL transmissions can also be called forward link transmissions. Downlink transmissions may be performed using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be performed using licensed frequency bands, unlicensed frequency bands, or both.

As mentioned in the background technology, there are a large number of multi-card terminals in the existing network. Taking a dual-card single-receive/send terminal as an example, if the terminal is currently working on the SIM-A card, it needs to periodically monitor the SIM-A card. The paging message of card B is used to judge whether there is a service with higher priority arriving on SIM-B. In order to notify the terminal of the service situation of the SIM-B card, a possible technical solution is to indicate the type or priority of the service in the paging message sent to the SIM-B card, such as Voice over Long-Term Evolution (Voice over Long- Term Evolution, VoLTE) or new air interface voice bearer (Voice over NR, VoNR) service, then the terminal needs to monitor the PDCCH first to see if there is a paging message scrambled by the Paging Radio Network Temporary Identifier (P-RNTI) , and then parse out the paging (paging) message to determine whether the type or priority of the arriving service is indicated. If the priority of the service carried in the paging message is low, the terminal does not need to switch to the SIM-B card to receive the service.

The embodiment of the present invention provides a service indication method, which can directly indicate the arriving service type or priority in the wake-up signal, so that the terminal can judge whether it needs to switch to SIM-B to receive the service only by deciphering the wake-up signal. The PDCCH is further monitored and the paging message is decoded, so that the power consumption of the terminal can be further saved.

To solve at least one of the above problems, an embodiment of the present invention provides a service indication method, which can save terminal power consumption. Referring to Figure 2, a service indication method provided by an embodiment of the present invention, when applied to a first terminal supporting at least a first SIM card and a second SIM card, includes:

Step 21: The first terminal performing the first service on the first SIM card receives a wake-up signal sent by the first network where the first SIM card resides, and the wake-up signal carries the information on the second SIM card. Arriving service indication information of the second service, wherein 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 standards and networks of the same communication standard).

Assuming that the first terminal performs the first service on the first SIM card, that is, the first SIM card is in a connected state on the corresponding first network (the first terminal is registered to the corresponding first network based on the first SIM card, The current state of the first terminal in the network is a connected state), and the second SIM card is in an idle state or an inactive state in the corresponding second network (the first terminal is based on the second SIM card register to the corresponding second network, the state of the first terminal in the network is idle state or 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 can 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 In this way, the network device can associate the service of the first SIM card in the connected state with the service of the second SIM card in the idle state/inactive state, and when the service of the second SIM card arrives, send the service to the first SIM card The service indication information used to indicate the second service. Specifically, the service indication information may be service type and/or priority information of the second service.

Through the above steps, when the first terminal in the embodiment of the present invention performs services on the first SIM card, it can know the service information arrived by other SIM cards without switching to other SIM cards, and realizes the service between SIM cards. instruct. Subsequently, the first terminal may determine whether to switch to another SIM card for response according to the received service information, thereby providing support for subsequent further reduction of power consumption of the multi-card terminal.

For example, after the above step 21, the above method in the embodiment of the present invention may further include the following step: the first terminal judges whether to switch to the second SIM card to perform the second service.

Here, the first terminal may judge whether to switch to the second SIM card to perform 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, continue to perform the first service through the first SIM card; and/or, when the priority of the first service is lower than or higher than that of the second service When the priority is not higher than that of the second service, switch to the second SIM card to perform the second service. That is to say:

When the priority of the first service is not lower than the priority of the second service, continue to carry out the first service through the first SIM card, and do not switch to the second SIM card at this time; and when the priority of the first service is low When the priority of the second service is selected, switch to the second SIM card to perform the second service;

Or, when the priority of the first service is higher than the priority of the second service, continue to carry out the first service through the first SIM card, and do not switch to the second SIM card at this time; When the priority level is not higher than the priority of the second service, switch to the second SIM card to perform the second service.

Through the above steps, the embodiment of the present invention realizes that when the first SIM card is in the connected state and the second SIM card is in the idle state/inactive state, the terminal can directly determine according to the wake-up signal received by the first SIM card. Whether it is necessary to switch to the second SIM card for business, it is not necessary to monitor the PDCCH on the second SIM card and analyze the paging message to decide whether to perform business on the second SIM card, avoiding unnecessary conversion processing between SIM cards , which can also save the power consumption and calculation overhead generated by monitoring the PDCCH and parsing 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 the comparison result that the priority of the first service is not lower than or higher than that of the second service;

In the case where the second service is a preset high-priority service, if the first service is a preset low-priority service, the priority of the first service is lower than or not higher than that of the second service If the first service has a preset high priority, then the comparison result that the priority of the first service is not lower than or higher than that of the second service is obtained.

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

Please refer to Figure 3, which provides the flow of the above service indication method applied to network equipment, including:

Step 31, the network device detects the arrival of the second service on the second SIM card of the first terminal, wherein the first SIM card of the first terminal is in a connected state, and the second SIM card is in an idle state or inactive state.

Here, the first SIM card and the second SIM card may reside in the same communication standard or networks of different communication standards operated by the same operator. In step 31, the network device may be a device in the network corresponding to the first SIM card, such as the first base station. When the first SIM card resides in the first network of a certain operator, and the second SIM card resides in the second network of the same operator (assuming that the first network and the second network are different), then the first base station The information of the second service sent by the second network to the second SIM card may be acquired through the inter-network interface. However, when both the first SIM card and the second SIM card reside in the same network of the same operator, at this time, the first base station can directly acquire the service information arriving on the second SIM card from the network. Of course, different networks can also provide services for the terminal in the form of public base stations. At this time, the public base stations can be connected to the core networks of different networks, so that it is convenient to obtain information about the services of each SIM card sent to the terminal by each network. .

Step 32: The network device sends a wake-up signal to the first terminal in the first network where the first SIM card resides, and the wake-up signal carries 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 PS-RNTI scrambled preset DCI, for example, the service indication information is carried in a preset field in the preset DCI, where the preset field The value corresponds to the priority of the second service, or corresponds to the service type of the second service.

Through the above steps, the embodiment of the present invention realizes that when the first SIM card of the first terminal is in the connected state, the indication information of the service arriving on other SIM cards of the first terminal is sent to the first SIM card, so that the When performing services on the first SIM card, the first terminal can learn the service information arrived by other SIM cards without switching to other SIM cards, thereby realizing the service indication between SIM cards. Subsequent terminals can determine whether to switch to other SIM cards to respond according to the arriving service information, so that there is no need to switch to other SIM cards to detect and PDCCH and parse paging messages, thereby avoiding unnecessary switching between SIM cards processing to save terminal power consumption.

To help better understand the above method embodiment, a more specific example of the above method embodiment is provided below.

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

S101. The network side (such as the base station) carries the service type or priority information arriving at the SIM-B in the WUS message sent to the SIM-A in the connected state of the UE. Specifically, this information can be carried in DCI format2_6 of WUS:

DCI format 2_6 scrambled by PS-RNTI includes the following fields:

- Block number, such as block number 1, block number 2,..., block number N, each block (block) corresponds to one or a group of UEs;

The fields of each block include:

- Wake-up indication, 1 bit;

-Indication information related to carrier aggregation (SCell dormancy indication)

- business type or priority indication information, for example, use 1 bit to indicate whether high priority services such as VoLTE or VoNR arrive, and if the bit position is 1, it means that high priority services such as VoLTE or VoNR arrive; this bit If the position is 0 or the bit is empty, it means that no high-priority services such as VoLTE or VoNR arrive or that the priority of the arriving services is general or not high; another example is to use multiple bits to identify the type of arriving services, such as two bits Bit, when the value is 00, it means the voice service, when the value is 01, it means the Internet service, etc.

S102. After the terminal receives the WUS message, it judges whether it needs to switch to the SIM-B to receive the service according to the service type or priority indication information of the SIM-B carried therein:

1) When the WUS message indicates that SIM-B has VoLTE or VoNR and other high-priority services arriving:

If the current UE is performing normal priority data services on SIM-A, the UE can switch to SIM-B to receive high priority services such as VoLTE or VoNR;

If the current UE is performing high-priority services such as VoLTE or VoNR on SIM-A, the UE can continue to work on SIM-A.

2) If the WUS message indicates that no high-priority services such as VoLTE or VoNR arrive on SIM-B, or the arriving services have a general or low priority, the UE can continue to work on SIM-A.

When the program is executed by the processor, it can realize all the implementation methods in the above-mentioned service indication method applied to the network equipment, and can achieve the same technical effect. To avoid repetition, details are not repeated here.

It is considered that in some cases, there are certain difficulties in the exchange of service state information between different SIM cards of the terminal. For example, when two SIM cards belong to different operators, it may be necessary to pre-establish an interface for information exchange between network devices of different operators.

In order to reduce the impact of different above-mentioned situations on the implementation of the solution of the present invention, other embodiments of the present invention also provide another service indication method, which can also be applied to the first terminal that supports at least the first SIM card and the second SIM card , here, the first SIM card and the second SIM card may reside in networks of the same operator with the same communication standard or different communication standards, or may reside in networks of different operators. As shown in Figure 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, and the wake-up signal carries a service indication of the second service information, the second SIM card is in an idle state or an inactive state.

Through the above steps, when the first terminal performs business in the first network corresponding to the first SIM card, it can detect the wake-up signal sent by the second network corresponding to the second SIM card, thereby realizing the communication between different SIM cards. The indication of service arrival provides support for the subsequent terminal to decide whether to switch to the second SIM card for further detection.

In order to reduce the number of wake-up signals, in the above-mentioned step 81 in the embodiment of the present invention, the first terminal may detect the wake-up signal according to the wake-up signal detection timing of the first terminal group to which the first terminal belongs, wherein the The above-mentioned wake-up signal detection timing is a pre-agreed timing, which may specifically include at least one of the following:

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

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

3) A second preset time before the paging opportunity (PO), where the second preset time may be a preset length of time, and the duration of the second preset time may be the same as or different from the first preset time.

In the above step 81, the first terminal detects the wake-up signal in the second network where the second SIM card resides according to the above-mentioned wake-up signal detection timing, and the wake-up signal carries the indication information of the service that the first terminal group arrives, for example , after a certain terminal (which may be the first terminal or other terminals) in the first terminal group arrives at a certain service, the second network will send a wake-up signal at the timing of the above-mentioned wake-up signal detection, and the terminal in the first terminal group is in A terminal in a dormant state will wake up at the above-mentioned wake-up signal detection timing to detect a 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 the International Mobile Subscriber Identity (IMSI) or Temporary Mobile Subscription Identifier (TMSI) or S-TMSI of the second SIM card of the terminal, such as mod 1024 operation, and the remainder The same terminals are in the same group. In the embodiment of the present invention, the foregoing grouping may also be performed in the same manner as the grouping manner for receiving paging messages. Optionally, the grouping mode may be pre-agreed or specified by the operator.

According to other embodiments of the present invention, after the above step 81, the above method in the embodiment of the present invention may further include the following steps: the first determination whether to detect the paging message sent by the second network to the 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. specific,

1) In the case where the detection result of the wake-up signal indicates that the wake-up signal has not been 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 the paging message sent by the second network to the second SIM card; and/or, when the first service is a preset When the low priority service is set, the terminal will detect the paging message sent by the second network to the second SIM card. Through the above method, the embodiment of the present invention can prevent the terminal from detecting paging messages on the second SIM card when the first service is a preset high-priority service, thereby saving the terminal from detecting paging messages on the PDCCH and PDSCH. The power consumption and computational overhead incurred by the message.

2) In the case where 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 by the second network to the second SIM card is not detected; and/or, when the priority of the first service When the priority is lower than the priority of the second service, detect the paging message sent by the second network to the second SIM card.

For another example, when the priority of the first service is higher than the priority 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 When the priority is not higher than the priority of the second service, detect the paging message sent by the second network to the second SIM card.

Through the above method, the embodiment of the present invention can prevent the terminal from detecting paging messages on the second SIM card when the priority of the second service does not meet the preset condition, thereby saving the terminal from detecting paging messages on the PDCCH and PDSCH. Power consumption and computing overhead generated by call messages to ensure the reliability of high-priority services.

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

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

In the 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 can be used in embodiments of the present invention are provided below:

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

Here, the preset RNTI may be a pre-agreed or pre-defined RNTI. For example, a DCI format (such as format 2_X, where x represents a value) and a new RNTI may be pre-defined, that is, a temporary identifier for an unconnected power-saving radio network (iPS-RNTI) described herein. In this way, the service indication information may be carried in a preset field in a preset DCI scrambled by a preset iPS-RNTI, where the value of the preset field corresponds to the priority of the second service , or correspond to the service type of the second service.

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

The embodiment of the present invention can define a set of algorithms for calculating the physical layer sequence (sequence), one or a group of terminals has a set of corresponding physical layer sequences, for example, different terminal groups correspond to different physical layer sequences, and/or, the same terminal In the grouping, different service types or service priorities correspond to different physical layer sequences. The sending timing of the physical layer sequence may coincide with a paging opportunity (PO). In this way, when the terminal detects the corresponding physical layer sequence, it can determine that a wake-up signal has been detected, which indicates that a new service has arrived in the packet to which the terminal belongs.

Please refer to FIG. 9, which provides a flow of the above service indication method applied to a network device in a second network, the second network is a network where the second SIM card of the first terminal resides, as shown in FIG. 9, The method includes:

In step 91, the arrival of the second service on the second SIM card of the first terminal is detected, 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.

Step 92: Send a wake-up signal to the first terminal, where the wake-up signal carries 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 the timing for sending the wake-up signal of the first terminal group to which the first terminal belongs, where the timing for sending the wake-up signal includes at least one of the following: A wake-up time in a continuous reception (DRX) cycle; a first preset time before DRX ON of a DRX cycle; a second preset time before a paging opportunity (PO).

Through the above steps, the network device in the embodiment of the present invention sends a wake-up signal at the timing of sending the wake-up signal, so that the terminal that is doing business on another SIM card can determine whether to detect paging on the second SIM card according to the wake-up signal. messages, thereby avoiding the power consumption and computing overhead caused by the terminal detecting unnecessary paging messages, and ensuring the reliability of high-priority services.

As mentioned above, the wake-up signal may be a preset DCI scrambled by a preset RNTI, or a preset physical layer sequence. In the case where the wake-up signal is a preset DCI scrambled by a preset RNTI, the service indication information is carried in a preset field in the preset DCI scrambled by a PS-RNTI, wherein the preset The value of the field corresponds to the priority of the second service, or corresponds to the service type of the second service; when the wake-up signal is a preset physical layer sequence, different terminal groups correspond to different and/or, in the same terminal group, different service types or service priorities correspond to different physical layer sequences.

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

In order to help better understand the above method embodiment, the above embodiment will be further described below through a more specific example.

Example 2:

In Example 2, it is assumed that a certain UE includes two SIM cards, namely SIM-A and SIM-B, and the two SIM cards belong to different operators.

S201. Group the terminals according to a certain scheme, for example, perform a mod1024 operation on the IMSI or TMSI or S-TMSI of the UE, and group the terminals with the same remainder into the same group. Alternatively, terminal grouping is performed in a manner consistent with the grouping manner of receiving paging messages. The grouping mode is pre-agreed or stipulated by the operator.

S202. Define a new set of iWUS mechanisms suitable for idle and/or inactive states, such as

1) Define a set of DCI format (such as format 2_x) and iWUS RNTI (such as iPS-RNTI) by way of DCI format. Among them, DCI format 2_x uses iPS-RNTI to perform cyclic redundancy check (Cyclic RedundancyCheck, CRC) scrambling, and its content includes:

- Business type or priority indication information, such as 1 bit indicating whether there is a high-priority business such as VoLTE or VoNR arriving, the bit position 1 indicates that a high-priority business such as VoLTE or VoNR arrives, the bit position is 0 or the bit If the bit is empty, it means that no high-priority business such as VoLTE or VoNR arrives or the priority of the arriving business is general or not high; or multiple bits are used to identify the type of business arriving, for example, two bits are used, where 00 means Voice service, 01 means Internet service, etc.

2) By means of physical layer sequence code (sequence), a set of sequence calculation mechanism is pre-defined. One or a group of UEs has a set of corresponding sequence, and the sending timing of sequence can be consistent with the paging opportunity (PO).

When the UE detects the corresponding sequence, it can be considered that there is a high-priority service sent to the UE in this group; further, different sequences can be defined for different services, such as sequence X for voice services, sequence Y for online services, etc. .

S303. SIM-B works in idle or inactive UE, wakes up in each DRX cycle, or a period of time before DRX ON arrives (such as N ms, N TTIs, etc., which can be pre-defined or configured by the network side through broadcast messages ), or a period of time before PO, use iPS-RNTI to check the common (common PDCCH), or to check the sequence, to determine whether the network side has sent the iWUS for this group of UEs.

1) If the UE does not detect the iWUS indication information, it means that no high-priority service arrives at the UE in this group, and the UE can judge whether it needs to further check the paging message according to the service priority of another SIM-A.

For example, if SIM-A is currently working on a high-priority voice service, the UE may not further detect the paging message on the SIM-BPDSCH, because even if there is a service on SIM-B, the priority is relatively low or not higher than that of SIM-B. For the service of A, the UE should not switch to SIM-B for this service. In this way, the overhead of the UE to detect the paging message on the PDSCH, as well as the power consumption and calculation overhead of the UE can be saved.

2) If the UE decodes the iWUS indication information, indicating that there is a high-priority service arriving in this group of UEs, then the UE further detects the paging message to see whether there is a high-priority service arriving from the UE. If there is, the UE can switch to SIM-B to perform 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 UE can save the PDSCH Detect the overhead of the paging message, and save the power consumption and calculation overhead of the UE.
