Fig. 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present application, which may include: a terminal 11 and an access network 12.
The terminal 11 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of User Equipment (UE), Mobile Station (MS), terminal (terminal device), and so on. For convenience of description, the above-mentioned devices are collectively referred to as a terminal.
In this embodiment, the terminal 11 may be a multi-card and multi-pass terminal. The multi-card multi-communication terminal is a terminal which is simultaneously provided with at least two SIM cards, and the two SIM cards can simultaneously work in a standby receiving state and a connection state. Fig. 1 illustrates an example in which a terminal 11 is a dual-card terminal, in which a SIM card 1 and a SIM card 2 are provided.
Optionally, the SIM card in the terminal 11 may be a common SIM card, or may also be an upgraded SIM card, such as a Universal Subscriber Identity Module (USIM) card; the SIM card may be a hardware SIM card or a software SIM card, which is not limited in this disclosure.

In this embodiment, the apparatus for providing a wireless communication function for a terminal is collectively referred to as a network device.
The network device 120 and the terminal 11 communicate with each other through some air interface technology, for example, a Uu interface. In the embodiment of the present application, each SIM card communicates with the corresponding network device 120 through the terminal 11.
The method for solving the network system interference provided by the embodiments of the present application is used in the communication system shown in fig. 1. It should be noted that the communication system and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it is known by a person skilled in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems along with the evolution of the communication system and the appearance of a new service scenario.
The problem of network system interference in a multi-card multi-pass terminal is not obvious in a Long Term Evolution (LTE) communication system, and in a 5G communication system, due to the fact that communication frequency bands are increased and frequency band differences owned by different operators are large, the situation that mutual interference of transmitting and receiving signals occurs easily in the multi-card multi-pass terminal is caused. In addition, because network interfaces do not exist between different operator networks, the operator networks cannot solve interference when the multi-card multi-channel terminal interferes.
In an illustrative example, as shown in fig. 2, the SIM card 1 in the terminal operates in an n78 frequency Band (uplink transmission frequency is 1710Mhz to 1785Mhz, and downlink reception frequency is 1805Mhz to 1880Mhz), and the SIM card 2 operates in a Band (Band)3 frequency Band (uplink transmission frequency and downlink reception frequency are both 3300Mhz to 3800 Mhz). When the SIM card 1 and the SIM card 2 are in a connected state at the same time, 2-order intermodulation (1515Mhz to 2090Mhz) generated by the uplink transmitting frequency Band of n78 and the uplink transmitting frequency Band of Band3 may cause intermodulation interference to the downlink receiving frequency Band of Band3, and affect signal reception of the SIM card 1; the 2 nd harmonic (3420Mhz to 3570Mhz) generated by the uplink transmitting frequency of Band3 will cause harmonic interference to the downlink receiving frequency Band of n78, and affect the signal reception of SIM card 2.
In order to solve the above problem, in this embodiment of the present application, for a multi-card and multi-pass terminal, when it is detected that interference exists between network systems corresponding to at least two SIM cards, a resource adjustment request is sent to a network device corresponding to a target SIM card in the at least two SIM cards, so that the network device corresponding to the target SIM card can configure time-frequency domain resources of the target SIM card according to interference solution auxiliary information and an interference type included in the resource scheduling request, thereby solving the problem of interference existing between the network systems, and facilitating improvement of communication quality of the multi-card and multi-pass terminal.
Please refer to fig. 3, which shows a flowchart of a method for solving network type interference according to an embodiment of the present application. The present embodiment is illustrated by applying the method to the communication system shown in fig. 1. The method comprises the following steps:
step 301, if there is interference between network systems corresponding to at least two SIM cards in the terminal, the terminal sends a resource adjustment request to a network device corresponding to a target SIM card in the at least two SIM cards, where the resource adjustment request includes interference resolution auxiliary information.
In the embodiment of the present application, the terminal has a function of detecting interference between network systems, and optionally, when at least two SIM cards are in a working state (i.e., in a connected state) at the same time, the terminal detects whether interference exists between network systems corresponding to the at least two SIM cards.
Optionally, the terminal further has a function of identifying a type of interference between network systems, where the type of interference includes at least one of intermodulation interference and harmonic interference. Correspondingly, if the interference between the network systems is detected, the terminal sends a resource adjustment request containing the interference type to the network equipment to request the network equipment to reconfigure the time-frequency resources allocated to the corresponding SIM card. Wherein the interference type may be included in the interference resolution assistance information or the interference type may be independent of the interference resolution assistance information.
Optionally, the target SIM card is at least one of the at least two SIM cards. In a possible implementation manner, the service priority of the target SIM card is lower than the service priorities of other SIM cards, or the target SIM card is an SIM card corresponding to the interfered network system. In other possible embodiments, the terminal may send resource adjustment requests to network devices corresponding to at least two SIM cards (the interference solution assistance information sent to different network devices is different).
Step 302, the network device receives a resource adjustment request sent by the terminal.
Optionally, the network device corresponding to the target SIM card receives the resource adjustment request sent by the terminal, and obtains the interference solution auxiliary information included in the resource adjustment request.
Step 303, the network device adjusts the time-frequency resource configured for the target SIM card according to the interference resolution auxiliary information.
Further, the network device eliminates the interference between the network systems by adjusting the time-frequency resources configured for the target SIM card according to the interference solution auxiliary information.
In a possible implementation manner, the network device sends the adjusted time-frequency resource information to the terminal through a Physical Downlink Control Channel (PDCCH), and the terminal sets the target SIM card according to the time-frequency resource information.
To sum up, in the embodiment of the present application, when it is detected that interference exists between network systems corresponding to at least two SIM cards, a resource adjustment request is sent to a network device corresponding to a target SIM card in the at least two SIM cards, so that the network device corresponding to the target SIM card can solve auxiliary information according to the interference included in the resource scheduling request, and configure time-frequency domain resources of the target SIM card, thereby solving the problem of interference among the network systems, and contributing to improving communication quality of a multi-card and multi-pass terminal.
In a possible implementation manner, the manner for the terminal to detect whether there is interference between network systems may include at least one of the following two manners: 1. the terminal determines whether interference exists according to time-frequency domain resources corresponding to at least two SIM cards; 2. and the terminal determines whether interference exists according to the downlink receiving rates corresponding to the at least two SIM cards. The following describes the above two ways by taking an example in which the terminal includes the first SIM card and the second SIM card.
1. And the terminal determines whether interference exists according to the time-frequency domain resources corresponding to the at least two SIM cards.
Optionally, the terminal may determine whether there is interference based on the time-frequency domain resource of the SIM card, and also determine a specific interference type of the interference, and a process of detecting whether there is intermodulation interference is described below.
First, a first uplink time-frequency domain resource and a first downlink time-frequency domain resource of a first SIM card are obtained.
In a possible implementation manner, the terminal acquires a first uplink time-frequency domain resource and a first downlink time-frequency domain resource, which are configured (configured through the PDCCH) by the network device corresponding to the first SIM card. The first uplink time-frequency domain resource comprises a first uplink time-frequency domain resource and a first uplink frequency-frequency domain resource, and the first downlink time-frequency domain resource comprises a first downlink time-frequency domain resource and a first downlink frequency-frequency domain resource. Optionally, the time domain resource may be at least one of a slot resource location, a subframe resource location, or a symbol resource location.
In an illustrative example, the terminal obtains a first uplink frequency domain resource of the first SIM card as [ f [ ]TL1，f TH1]The first downlink frequency domain resource is [ f ]RL1，f RH1]。
And secondly, acquiring a second uplink time-frequency domain resource and a second downlink time-frequency domain resource of the second SIM card.
Similar to the above steps, the terminal obtains a second uplink time-frequency domain resource and a second downlink time-frequency domain resource, which are configured (configured through the PDCCH) for the network device corresponding to the second SIM card. The second uplink time-frequency domain resource comprises a second uplink time-frequency domain resource and a second uplink frequency-frequency domain resource, and the second downlink time-frequency domain resource comprises a second downlink time-frequency domain resource and a second downlink frequency-frequency domain resource. Optionally, the time domain resource may be at least one of a slot resource location, a subframe resource location, or a symbol resource location.
In an illustrative example, the terminal obtains a second uplink frequency domain resource of a second SIM card as [ f [ ]TL2，f TH2]The second downlink frequency domain resource is [ f ]RL2，f RH2]。
And thirdly, determining the intermodulation interference time-frequency domain resource according to the first uplink time-frequency domain resource and the second uplink time-frequency domain resource.
Since the intermodulation interference is generated when two paths of signals are transmitted simultaneously and affects signal reception, in a possible implementation manner, the terminal determines the intermodulation interference frequency domain resource according to the first uplink frequency domain resource and the second uplink frequency domain resource, and determines the intermodulation interference time domain resource according to the first uplink time domain resource and the second uplink time domain resource, thereby determining the intermodulation interference time domain resource.
Optionally, the intermodulation interference frequency domain resources corresponding to the m + n-order intermodulation products are: m × (first uplink frequency domain resource) ± (second uplink frequency domain resource); the intermodulation interference frequency domain resource is the intersection of the first uplink time domain resource and the second uplink time domain resource.
And if the intermodulation interference time-frequency domain resource and the interfered downlink time-frequency domain resource have intersection on the frequency domain and the time domain, determining that the intermodulation interference exists, wherein the interfered downlink time-frequency domain resource is at least one of the first downlink time-frequency domain resource and the second downlink time-frequency domain resource.
In a possible implementation manner, the terminal detects whether an intersection exists between the intermodulation interference frequency domain resources and downlink frequency domain resources corresponding to a SIM card (any one of the first SIM card and the second SIM card) (i.e., whether the intermodulation interference frequency domain resources overlap in frequency domain); if the detected interference exists, further detecting whether an intersection exists between the intermodulation interference time domain resource and the downlink time domain resource corresponding to the SIM card (namely whether the time domains are overlapped), if so, determining that the SIM card is an interfered SIM card (correspondingly, the downlink time domain resource corresponding to the interfered SIM card is the interfered time domain resource), and if not, determining that the SIM card is not subjected to intermodulation interference.
Optionally, when it is determined that the m + n-order intermodulation product causes interference to the interfered SIM card, the terminal further determines the interfered downlink frequency domain range according to an intersection of the intermodulation interference frequency domain resource and the interfered downlink frequency domain resource in the frequency domain.
After determining that the intermodulation interference exists, the terminal may send a resource adjustment request including interference resolution assistance information and an intermodulation interference type to the network device.
The above-mentioned embodiment describes a process of detecting intermodulation interference, and the following description continues to describe a process of detecting whether harmonic interference exists.
The method comprises the steps of determining harmonic interference time-frequency domain resources, wherein the harmonic interference time-frequency domain resources comprise first harmonic interference time-frequency domain resources corresponding to first uplink time-frequency domain resources and second harmonic interference time-frequency domain resources corresponding to second uplink time-frequency domain resources.
In a possible implementation manner, a terminal acquires a first uplink time-frequency domain resource corresponding to a first SIM card, so as to determine that a first harmonic interference frequency domain resource corresponding to an m-th harmonic product is mx (first uplink frequency domain resource), and the first harmonic interference time domain resource is a first uplink time domain resource; the terminal acquires a second uplink time-frequency domain resource corresponding to a second SIM card, thereby determining that a second harmonic interference frequency domain resource corresponding to an nth harmonic product is nxx (the second uplink frequency domain resource), and the second harmonic interference time domain resource is the second uplink time domain resource.
And secondly, if the harmonic interference time-frequency domain resource and the interfered downlink time-frequency domain resource have intersection in the frequency domain and the time domain, determining that the harmonic interference exists.
In a possible implementation manner, the terminal detects whether an intersection exists between the harmonic interference frequency domain resource and a downlink frequency domain resource corresponding to the SIM card (any one of the first SIM card and the second SIM card) (i.e., whether the frequency domains overlap or not); if the harmonic interference time domain resource exists, whether an intersection exists between the harmonic interference time domain resource and the downlink time domain resource corresponding to the SIM card (namely whether the time domains are overlapped) is further detected, if the intersection exists, the SIM card is determined to be the interfered SIM card (correspondingly, the downlink time domain resource corresponding to the interfered SIM card is the interfered downlink time domain resource), and if the intersection does not exist, the SIM card is determined not to be subjected to the harmonic interference.
Optionally, when it is determined that the harmonic product causes interference to the interfered SIM card, the terminal further determines the interfered downlink frequency domain range according to an intersection of the harmonic interference frequency domain resource and the interfered downlink frequency domain resource in the frequency domain.
After determining that the harmonic interference exists through the steps, the terminal can send a resource adjustment request containing interference resolution auxiliary information and the type of the harmonic interference to the network equipment.
By adopting the method provided by the embodiment, whether interference exists between network systems can be quickly detected under the condition that normal communication of the terminal is not influenced, the interference type can be accurately detected, and subsequent interference elimination is facilitated.
2. And the terminal determines whether interference exists according to the downlink receiving rates corresponding to the at least two SIM cards.
First, under the condition that a first SIM card and a second SIM card work simultaneously, a first downlink receiving rate of the first SIM card and a second downlink receiving rate of the second SIM card are obtained.
When there is interference between network systems corresponding to the SIM card, the signal reception of the SIM card is affected, thereby affecting the downlink reception rate thereof, and therefore, the terminal may determine whether there is interference based on the downlink reception rate corresponding to the SIM card.
In a possible implementation manner, the terminal performs downlink receiving rate test on the first SIM card and the second SIM card at the same time (the two SIM cards work at the same time), so as to obtain a first downlink receiving rate and a second downlink receiving rate.
Since the ongoing service on the SIM card may be affected when the downlink receiving rate test is performed on the first SIM card and the second SIM card, in a possible implementation, the terminal performs the downlink receiving rate test when the first SIM card and the second SIM card perform a high-latency service or when the first SIM card and the second SIM card perform a low-reliability service.
And secondly, if the first speed difference between the first downlink receiving speed and the third downlink receiving speed is larger than or equal to a first threshold value, and/or the second speed difference between the second downlink receiving speed and the fourth downlink receiving speed is larger than or equal to a second threshold value, determining that the interference exists.
In a possible implementation manner, when the first SIM card and the second SIM card do not operate simultaneously (have the same or similar downlink time-frequency resource configuration as that of the first SIM card and the second SIM card), the terminal respectively tests a third downlink receiving rate of the first SIM card and a fourth downlink receiving rate of the second SIM card. When detecting whether interference exists, the terminal detects whether a first speed difference value between a first downlink receiving speed and a third downlink receiving speed is larger than or equal to a first threshold value, detects whether a second speed difference value between a second downlink receiving speed and a fourth downlink receiving speed is larger than or equal to a second threshold value, and if at least one of the first speed difference value and the second speed difference value is satisfied, the terminal determines that interference exists.
Optionally, if the first speed difference is greater than or equal to the first threshold, the terminal determines that the first SIM card is interfered; and if the second speed difference value is larger than or equal to the second threshold value, the terminal determines that the second SIM card is interfered.
In a possible implementation manner, the terminal may further determine an interference degree according to the first rate difference and/or the second rate difference, where the interference degree is in a positive correlation with the first rate difference and/or the second rate difference, that is, a larger rate difference indicates that the network system to which the SIM card corresponds is subjected to a larger interference.
Optionally, if the interference degrees are greater than the interference degree threshold, the terminal sends a resource adjustment request to the network device corresponding to the target SIM card; otherwise, no resource adjustment request will be sent.
By adopting the method provided by the embodiment, the difference of the downlink receiving rates when the SIM cards work simultaneously and do not work simultaneously is measured and compared, whether the interference occurs can be determined, the interference degree can be determined based on the difference of the downlink receiving rates, and the method is favorable for requesting the network equipment to solve the interference when the serious interference occurs.
It should be noted that the above two ways of determining whether there is interference may be performed alternatively or in combination.
In a possible implementation manner, when the two manners are executed in combination, the terminal may first determine whether there is interference and an interference type based on the time-frequency domain resource of the SIM card; when the interference types are intermodulation interference, the order (m + n) of the intermodulation interference is greater than an order threshold (such as 5), or the interference types are harmonic interference, and the times (m or n) of the harmonic interference are greater than a times threshold (such as 5), determining the interference degree based on the downlink receiving rate of the SIM card (because the interference degree of the high-order intermodulation is less than that of the low-order intermodulation, the interference degree of the high-order harmonic is less than that of the low-order intermodulation); if the interference degrees are larger than the interference degree threshold value, the terminal sends a resource adjustment request to network equipment corresponding to the target SIM card; and if the interference degrees are smaller than the interference degree threshold value, the terminal does not send a resource adjustment request. Therefore, the two modes are combined to be executed, so that the interference type and the interference degree can be determined at the same time, and the interference can be solved based on the interference type and the interference degree.
In the above embodiment, a process of determining whether there is interference by the terminal is described, and a process of requesting the network device to solve interference by sending interference solution information with different contents by the terminal is described below by using an exemplary embodiment.
Please refer to fig. 4, which shows a flowchart of a method for solving network type interference according to another embodiment of the present application. The present embodiment is illustrated by applying the method to the communication system shown in fig. 1. The method comprises the following steps:
step 401, if there is interference between network systems corresponding to at least two SIM cards in the terminal, the terminal sends a resource adjustment request to a network device corresponding to a target SIM card in the at least two SIM cards, where the resource adjustment request includes frequency domain resources of other SIM cards.
Wherein, the other SIM cards are the SIM cards except the target SIM card in the at least two SIM cards.
In a possible implementation manner, the terminal determines the SIM card with a lower service priority as the target SIM card, so that when detecting that there is network system interference, the terminal sends the interference type including the frequency domain resources of other SIM cards to the network device corresponding to the target SIM card, so that the network device adjusts the frequency domain resources configured for the target SIM card.
By sending the resource adjustment request to the network device corresponding to the low-service-priority SIM card, the influence on the high-service-priority SIM card can be avoided, and the normal execution of the high-priority service is ensured.
Step 402, the network device receives a resource adjustment request sent by the terminal.
Step 403, the network device adjusts the uplink frequency domain resource and/or the downlink frequency domain resource configured for the target SIM card according to the frequency domain resources of other SIM cards.
When there is intermodulation interference or harmonic interference, the network device may reduce the influence of the intermodulation product or the harmonic product on the downlink received signal by adjusting the frequency domain resource configured for the target SIM card.
In a possible implementation manner, when the interference type is intermodulation interference, the network device adjusts the uplink frequency domain resource and/or the downlink frequency domain resource corresponding to the target SIM card according to the current frequency domain resource corresponding to the target SIM card and the frequency domain resources corresponding to other SIM cards, and it is ensured that after adjustment, there is no intersection between the intermodulation interference time domain resource and the downlink time domain resource of each SIM card in the frequency domain, thereby eliminating the intermodulation interference.
In another possible implementation, when the interference type is harmonic interference, the network device adjusts the uplink frequency domain resource and/or the downlink frequency domain resource corresponding to the target SIM card according to the current frequency domain resource corresponding to the target SIM card and the frequency domain resources corresponding to other SIM cards, and ensures that after adjustment, there is no intersection between the harmonic interference time domain resource and the downlink time domain resource of each SIM card in the frequency domain, thereby eliminating the harmonic interference.
In this embodiment, the terminal sends the frequency domain resources corresponding to the other SIM cards to the network device, so that the network device can adjust the frequency domain resources corresponding to the SIM cards based on the frequency domain resources corresponding to the network device and the frequency domain resources of the other SIM cards, thereby eliminating interference; in addition, by adopting the mode, the terminal can still keep the simultaneous transmission and reception of the multiple SIM cards, and the throughput of the terminal is ensured.
In addition to adjusting the frequency domain resources, the network device may also adjust the time domain resources allocated to the SIM card to solve the interference, and the following description will use an exemplary embodiment.
Please refer to fig. 5, which shows a flowchart of a method for solving network type interference according to another embodiment of the present application. The present embodiment is illustrated by applying the method to the communication system shown in fig. 1. The method comprises the following steps:
step 501, if there is interference between network systems corresponding to at least two SIM cards in the terminal, the terminal sends a resource adjustment request to a network device corresponding to a target SIM card in the at least two SIM cards, where the resource adjustment request includes time domain resources of other SIM cards.
In a possible implementation manner, the terminal determines the SIM card with a lower service priority as the target SIM card, so that when detecting that there is network system interference, the terminal sends the interference type including the time domain resources of other SIM cards to the network device corresponding to the target SIM card, so that the network device adjusts the time domain resources configured for the target SIM card.
By sending the resource adjustment request to the network device corresponding to the low-service-priority SIM card, the influence on the high-service-priority SIM card can be avoided, and the normal execution of the high-priority service is ensured.
Step 502, the network device receives a resource adjustment request sent by the terminal.
Step 503, the network device adjusts the uplink time domain resource configured for the target SIM card according to the time domain resources of other SIM cards.
When intermodulation interference or harmonic interference exists, the network equipment can stagger the time domain resources of intermodulation products or harmonic products and the downlink time domain resources of each SIM card by adjusting the uplink time domain resources configured for the target SIM card, so that the downlink signal receiving is prevented from being influenced.
In a possible implementation manner, when the interference type is intermodulation interference, the network device adjusts the uplink time domain resource corresponding to the target SIM card according to the current uplink time domain resource corresponding to the target SIM card and the uplink time domain resources corresponding to other SIM cards, and ensures that the adjusted uplink time-frequency resources corresponding to the target SIM card and the other SIM cards are staggered (non-intersected), thereby avoiding intermodulation interference (throughput may be reduced).
In another possible implementation, when the interference type is harmonic interference, the network device adjusts the uplink time domain resource corresponding to the target SIM card according to the current uplink time domain resource corresponding to the target SIM card and the downlink time domain resources corresponding to other SIM cards, and ensures that the uplink time domain resource of the target SIM card is staggered with the downlink time domain resources corresponding to other SIM cards after adjustment, thereby avoiding harmonic interference (throughput may be reduced).
In this embodiment, the terminal sends the time domain resources corresponding to the other SIM cards to the network device, so that the network device can adjust the uplink time domain resources corresponding to the SIM cards based on the time domain resources corresponding to the SIM cards and the time domain resources of the other SIM cards, thereby fundamentally avoiding harmonic interference and intermodulation interference.
Except that the network device adjusts the time domain resources corresponding to other SIM cards, the terminal may also determine the configuration of the transceiving time domain resources (which may be time slots, subframes, or symbols) corresponding to each SIM card when determining that there is interference, and send the determined configuration of the transceiving time domain resources to the corresponding network device, so that the network device directly configures the configuration. The following description will be made by using exemplary embodiments.
Please refer to fig. 6, which shows a flowchart of a method for solving network type interference according to another embodiment of the present application. The present embodiment is illustrated by applying the method to the communication system shown in fig. 1. The method comprises the following steps:
step 601, if intermodulation interference exists between network systems corresponding to at least two SIM cards in the terminal, the terminal sends a resource adjustment request to a network device corresponding to a target SIM card in the at least two SIM cards, where the resource adjustment request includes an emission time domain resource configuration, and there is no intersection between emission time domain resources indicated by emission time domain resource configurations corresponding to different SIM cards in the at least two SIM cards.
In a possible implementation manner, when intermodulation interference exists between network systems of the terminal, the terminal generates emission time domain resource configurations corresponding to each SIM card according to the respective time domain resources corresponding to each SIM card on the premise of ensuring that no intersection exists between the emission time domain resources corresponding to each SIM card.
Schematically, the transmission time domain resources configured for the first SIM card and the second SIM card by the terminal are as shown in fig. 7, and because there is no intersection between the transmission time domain resources (U) corresponding to the first SIM card and the second SIM card, the problem of intermodulation interference can be fundamentally avoided.
It should be noted that, when subframes corresponding to different network systems are not aligned, subframes of transmission time domain resources generated by the terminal for different SIM cards are also not aligned, and the embodiment shown in fig. 7 is only schematically illustrated by taking subframe alignment as an example.
Step 602, the network device receives a resource adjustment request sent by the terminal.
Step 603, the network device sets the uplink time domain resource of the target SIM card according to the transmission time domain resource configuration.
Further, after receiving the resource adjustment request, the network device sets the uplink time domain resource of the target SIM card according to the transmission time domain resource position indicated by the transmission time domain resource configuration.
Please refer to fig. 8, which shows a flowchart of a method for solving network type interference according to another embodiment of the present application. The present embodiment is illustrated by applying the method to the communication system shown in fig. 1. The method comprises the following steps:
step 801, if harmonic interference exists between network systems corresponding to at least two SIM cards in a terminal, the terminal sends a resource adjustment request to a network device corresponding to a target SIM card in the at least two SIM cards, where the resource adjustment request includes a transmit-receive time domain resource configuration, and the transmit-receive resource configuration includes a transmit time domain resource configuration and a receive time domain resource configuration, where, for any one of the at least two SIM cards, there is no intersection between a transmit time domain resource indicated by the transmit time domain resource configuration corresponding to the SIM card and a receive time domain resource indicated by the receive time domain resource configurations corresponding to other SIM cards, and the other SIM cards are the SIM cards except the SIM card in the at least two SIM cards.
In a possible implementation manner, when harmonic interference exists between network systems of the terminal, the terminal generates, according to the time domain resource corresponding to each SIM card, a transceiving time domain resource configuration corresponding to each SIM card on the premise of ensuring that no intersection exists between the transmitting time domain resource corresponding to any one of the at least two SIM cards and the receiving time domain resource corresponding to the other SIM card.
Schematically, the transceiving time domain resources configured for the first SIM card and the second SIM card by the terminal are as shown in fig. 9, and as there is no intersection between the transmitting time domain resource (U) corresponding to the first SIM card and the receiving time domain resource (D) corresponding to the second SIM card, the problem of harmonic interference can be fundamentally avoided. Wherein X in fig. 9 denotes a non-reception time domain resource including a transmission time domain resource and an unused time domain resource.
It should be noted that, when subframes corresponding to different network systems are not aligned, subframes of transmission time domain resources generated by the terminal for different SIM cards are also not aligned, and the embodiment shown in fig. 9 is only schematically illustrated by taking subframe alignment as an example.
Step 802, a network device receives a resource adjustment request sent by a terminal.
Step 803, the network device sets the uplink time domain resource and the downlink time domain resource of the target SIM card according to the configuration of the transceiving time domain resource.
Further, after receiving the resource adjustment request, the network device sets the uplink time domain resource and the downlink time domain resource of the target SIM card according to the transmission time domain resource position and the reception time domain resource position indicated by the transmission and reception time domain resource configuration.
In this embodiment, after the terminal locally generates the adjustment configuration policy, the terminal sends the corresponding configuration to the network device, so that the network device directly performs time domain resource adjustment, thereby reducing the processing pressure of the network device.
In a possible implementation manner, if the interference existing between the network systems corresponding to the at least two SIM cards is intermodulation interference, and the intermodulation interference cannot be solved (the intermodulation interference cannot be completely solved by adjusting the time-frequency domain resources), the terminal may reduce the influence of the intermodulation interference in at least one of the following manners.
1. And disconnecting the network corresponding to the low-priority SIM card in the at least two SIM cards, wherein the service priority of the low-priority SIM card is lower than the service priorities of other SIMs, and the other SIMs are the SIM cards except the low-priority SIM card in the at least two SIM cards.
In an illustrative example, when the service of the first SIM card is a voice call service and the service of the second SIM card is a data traffic service, since the service priority of the data traffic service is higher than the service priority of the voice call service, when intermodulation interference occurs in the network systems of the first SIM card and the second SIM card, the terminal disconnects the network of the first SIM card.
2. And simultaneously reducing the uplink transmitting power corresponding to at least two SIM cards.
3. And reducing the uplink transmitting power corresponding to the low-priority SIM card.
In order to avoid affecting the high-priority service, the terminal may only reduce the uplink transmission power corresponding to the low-priority SIM card, and maintain the uplink transmission power of the high-priority SIM card.
In another possible implementation, if interference existing between network systems corresponding to at least two SIM cards is harmonic interference and the harmonic interference cannot be solved (the harmonic interference cannot be completely solved by adjusting time-frequency domain resources), the terminal may reduce the influence of the harmonic interference in at least one of the following manners.
1. And disconnecting the network corresponding to the interfered SIM card in the at least two SIM cards, wherein the interfered SIM card is the SIM card subjected to harmonic interference. For example, when the harmonic generated when the first SIM card transmits uplink affects the downlink reception of the second SIM card, the second SIM card is the interfered SIM card.
2. And reducing uplink transmission power of an interference SIM card in the at least two SIM cards, wherein the interference SIM card is the SIM card generating harmonic interference. For example, when the harmonic generated when the first SIM card transmits uplink affects the downlink reception of the second SIM card, the first SIM card is the interfering SIM card.
It should be noted that the above embodiments can be freely combined; the step of taking the terminal as the execution subject can be separately implemented to be the solution of the network system interference at the terminal side, and the step of taking the network device as the execution subject can be separately implemented to be the solution of the network system interference at the network device side, which is not described herein again in this embodiment.
