[0035] The technical solution of the present application will be described in detail below through embodiments and in conjunction with the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0036] It should be noted that in the examples of the present application, "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0037] In addition, the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0038] Currently, mainstream terminal devices on the market generally support dual-SIM technology, that is, they can use two SIM cards provided by the same operator or different operators. Due to the different capabilities of the RF modules and baseband modules on various terminal devices, the mainstream dual-SIM technology can be divided into dual-SIM dual standby (DSDS) and dual-SIM dual access (DSDA).

[0039] The characteristic of dual-SIM dual-standby technology is that two cards use the terminal device's RF and baseband resources in a time-sharing manner. For example, when one card is transmitting data or making a call, the other card will release the terminal device's RF and baseband resources and be in standby mode. Although this technology can only switch between the two cards in a time-sharing manner, it has low requirements on the capabilities of the terminal device's baseband chip and RF chip and is easy to implement.

[0040] In some embodiments, the baseband module can only support the processing capacity of one carrier at a time, and the terminal device can at most support dual-card dual standby, but cannot support dual-card dual pass. In some embodiments, the RF module can only transmit signals through one antenna at a time, and the terminal device can at most support dual-card dual standby, but cannot support dual-card dual pass. In some embodiments, the baseband module can support the processing capacity of multiple carriers at a time, and the RF module can transmit signals through multiple antennas at a time, and the terminal device can support both dual-card dual pass and dual-card dual standby.

[0041] Figure 1 The following is a schematic diagram of the occupancy of radio frequency resources and baseband resources for dual SIM dual standby. Figure 1As shown, SIM1 and SIM2 occupy radio frequency resources and baseband resources in a time-division manner, wherein radio frequency resources and baseband resources not occupied by SIM1 and SIM2 are idle resources.

[0042] The technical feature of dual-SIM dual-pass is that, depending on the capabilities of the RF chip and baseband chip of the terminal device, part of the transmission capacity of one of the cards can be sacrificed to ensure that both cards can transmit data at the same time, or one card can transmit data and the other card can make calls, or both cards can make calls.

[0043] Figure 2 FIG. 1 is a schematic diagram of the occupation of radio frequency resources and baseband resources of a dual-card dual-channel system. Figure 2 As shown, Figure 2 The figure shows a scenario in which, in the case of dual-SIM dual-pass, one card occupies radio frequency resources and baseband resources at the same time, which will affect the occupation of radio frequency resources and baseband resources by another card. In the period from t1 to t2, SIM1 and SIM2 jointly occupy radio frequency resources and baseband resources, in the period from t2 to t3, SIM1 exclusively uses radio frequency resources and baseband resources, in the period from t3 to t4, SIM1 and SIM2 jointly occupy radio frequency resources and baseband resources, and in the period from t4 to t5, SIM2 exclusively uses radio frequency resources and baseband resources. Among them, radio frequency resources and baseband resources not occupied by SIM1 and SIM2 are idle resources.

[0044] In some cases, if the RF chip and baseband chip of the terminal device are strong enough, the transmission capacity of one card may not be sacrificed. This technology can maximize the ability of two cards to work at the same time, but it has high requirements on the capabilities of the RF chip and baseband chip.

[0045] Figure 3 FIG. 1 is another schematic diagram of the occupation of radio frequency resources and baseband resources of dual-card dual-channel. Figure 3 As shown, Figure 3 The figure shows the scenario where the RF and baseband capabilities are strong enough in the case of dual-SIM dual-channel. Figure 3 In the corresponding embodiment, SIM1 occupies the first part M1 of the radio frequency resources and baseband resources, SIM2 occupies the second part M2 of the radio frequency resources and baseband resources, and the radio frequency resources and baseband resources occupied by SIM1 do not affect the radio frequency resources and baseband resources occupied by SIM2. Among them, the radio frequency resources and baseband resources not occupied by SIM1 and SIM2 are idle resources.

[0046] Since dual-SIM dual-pass can better meet user needs, more and more terminal devices use dual-SIM dual-pass technology to ensure the overall performance of the terminal devices.

[0047] The terminal equipment will consider the cost and will not increase the RF and baseband capabilities indefinitely to meet the dual-SIM dual-pass requirements. Figure 3 The corresponding embodiment is not suitable for most terminal devices, most of which are generally Figure 2 In the corresponding embodiment, the two cards of the terminal device reduce their capabilities to keep both cards in a state of sending and receiving data, or fall back to Figure 1 The dual SIM dual standby state shown means that the dual SIM dual pass state cannot be maintained even by reducing the capacity.

[0048] The terminal device will always measure the signal quality of the signal in the adjacent cell and report it to the network device where the terminal device currently resides. When the network device receives the measurement report from the terminal device, it will also trigger the terminal device to switch to a better cell to ensure that the terminal device can always access a cell with relatively better signal quality during movement. However, this behavior of switching to a new cell may cause the combination of the frequency band of the new cell and the frequency band of the cell where the other SIM card is located to exceed the radio frequency capability, thus failing to maintain the dual-card dual-access (DSDA) state.

[0049] Figure 4 Schematic diagram of the process of terminal equipment changing from dual SIM dual pass state to dual SIM dual standby state, Figure 4 As shown, first, SIM1 corresponding to frequency band A and SIM2 corresponding to frequency band B jointly occupy radio frequency resources and baseband resources, and the terminal device is in a dual-card dual-active (DSDA) state, that is, frequency band A corresponding to SIM1 and frequency band B corresponding to SIM2 meet the total radio frequency capability. Then, due to the movement of the terminal device, SIM2 performs cell switching and switches to the cell corresponding to frequency band C. The frequency band combination of frequency band C and frequency band A does not meet the radio frequency capability of the terminal device, that is, frequency band A corresponding to SIM1 and frequency band C corresponding to SIM2 exceed the total radio frequency capability, so that the terminal device degenerates from the dual-card dual-active (DSDA) state to the dual-card dual-standby (DSDS) state, that is, SIM1 corresponding to frequency band A and SIM2 corresponding to frequency band C use radio frequency resources in a time-division manner. In some embodiments, not only frequency band A corresponding to SIM1 and frequency band B corresponding to SIM2 meet the total baseband capability, but frequency band A corresponding to SIM1 and frequency band C corresponding to SIM2 also meet the total baseband capability.

[0069] In some embodiments, when the first cell currently resident corresponding to the first user identification card and the third cell currently resident corresponding to the second user identification card are different cells, the terminal device needs to determine the measurement result corresponding to the first user identification card and the measurement result corresponding to the second user identification card.

[0078] In some embodiments, each time the terminal device determines the measurement result corresponding to the first user identification card and when it is determined that the measurement result corresponding to the first user identification card meets the switching condition, the terminal device reports the first information, the second information or the third information to the network device corresponding to the first cell.

[0079] In some embodiments, when it is determined according to the first measurement result and the second measurement result that the switching condition is met, and the frequency band of the second cell and the frequency band of the third cell currently residing corresponding to the second user identification card support simultaneous transmission, reporting first information to the network device corresponding to the first cell may include: determining according to the first measurement result and the second measurement result that the switching condition is met, and when it is determined according to the measurement result corresponding to the second user identification card that the switching condition is not met, and the frequency band of the second cell and the frequency band of the third cell currently residing corresponding to the second user identification card support simultaneous transmission, reporting the first information to the network device corresponding to the first cell.

[0083] In some embodiments, the first information may include first indication information, where the first indication is used to indicate that a frequency band of the second cell and a frequency band of a third cell currently residing corresponding to the second user identification card support simultaneous transmission.

[0084] In some embodiments, after the terminal device reports the first information to the network device corresponding to the first cell, the terminal device can receive a switching command sent by the network device corresponding to the first cell, and the terminal device switches the cell corresponding to the first user identification card from the first cell to the second cell according to the switching command.

[0085] In the embodiment of the present application, a first measurement result of a signal in a first cell currently resident corresponding to a first user identification card and a second measurement result of a signal in a second cell adjacent to the first cell are determined; when it is determined according to the first measurement result and the second measurement result that the switching condition is met, and the frequency band of the second cell and the frequency band of the third cell currently resident corresponding to the second user identification card support simultaneous transmission, first information is reported to the network device corresponding to the first cell; wherein the first information includes the first measurement result and the second measurement result. In this way, when the frequency band of the second cell and the frequency band of the third cell currently resident corresponding to the second user identification card support simultaneous transmission, the first information is reported, so that the cell corresponding to the first user identification card is switched from the first cell to the second cell, and after switching to the second cell, the terminal device can support the simultaneous transmission of the first user identification card and the second user identification card, so that in the cell switching process, the cell corresponding to the first user identification card is switched to the cell where the terminal device can support the simultaneous transmission of the first user identification card and the second user identification card as much as possible, so that the terminal device is in the simultaneous transmission state of the first user identification card and the second user identification card as much as possible, reducing the impact on service transmission and improving the reliability of data transmission.

[0087] In any embodiment of the present application, the measurement result B is greater than the measurement result A within the target duration, which may include: within the target duration, the measurement result B obtained by the i-th measurement is greater than the measurement result A obtained by the i-th measurement, where i is an integer greater than or equal to 1.

[0173] The embodiment of the present application proposes a design scheme that combines signal quality evaluation to maintain the current frequency band of the two cards, thereby keeping the two cards in the dual-card dual-pass (DSDA) mode as much as possible. The terminal device will always measure the signal quality of the adjacent cells and report it to the network device. Under the condition of ensuring a certain signal quality of the cell (i.e., the cell currently resident corresponding to the first user identification card), the network device will try not to trigger the cell switching instruction to the terminal device, so as to maintain the dual-card dual-pass (DSDA) state as much as possible. Or, at the expense of a certain acceptable range of signal quality, switch to a cell that can meet the dual-card dual-pass frequency band.

When the terminal device moves to position 2, the terminal device determines that the switching condition is met, and the terminal device determines whether the cell corresponding to network device A and the cell corresponding to network device B are applicable to dual-card dual-pass or dual-card dual-standby; when applicable to dual-card dual-pass, the cell corresponding to the first user identification card is switched from the cell corresponding to network device A to the cell corresponding to network device B; when applicable to dual-card dual-pass, if there is a network device C, the frequency band of the cell corresponding to the network device C is the same as that of the cell corresponding to the second user identification card. A frequency band combination between the frequency bands of the currently resident cell, applicable to dual-card dual-pass, and has the following characteristics: the measurement result of the cell corresponding to network device C is higher than the measurement result of the cell corresponding to network device B, or, and has the following characteristics: the measurement result of the cell corresponding to network device C is lower than the measurement result of the cell corresponding to network device B, and the difference between the measurement result of the cell corresponding to network device B and the measurement result of the cell corresponding to network device C is less than a third threshold, then the terminal device reports the third information to network device A to switch to network device C; otherwise, in the absence of a network device C, the terminal device reports the first information to network device A to switch to network device B.

[0175] In some embodiments of the present application, the terminal device may perform measurement and reporting based on at least one of signal quality, decoding success rate, network device frequency band, etc. during movement.

[0177] Step 1: A SIM card (corresponding to the first subscriber identity card (SIM)) of the terminal device resides on the network device A (corresponding to the first cell) and gradually moves to search for the network device B (corresponding to the second cell) and starts to measure the signal quality of the network device B. When the signal quality of the network device B gradually becomes better than that of the network device A, first determine whether the frequency band of the network device B and another SIM card (corresponding to the second subscriber identity card (SIM)) can maintain a dual-card dual-access (DSDA) state.

[0182] S1103. Determine whether the frequency band corresponding to the network device B and the frequency band corresponding to the currently resident network device corresponding to the second SIM (corresponding to the third cell mentioned above) can maintain dual-SIM dual-communication.

[0183] If the answer to S1103 is yes, the process goes to S1105 , and if the answer to S1103 is no, the process goes to S1106 .

[0185] S1105. Report normally.

[0186] In any embodiment of the present application, normal reporting may correspond to reporting the first information in the above embodiment. In any embodiment of the present application, normal reporting may be that the terminal device reports the first information to the network device A where the first SIM currently resides.

[0187] S1106, proceed to step 2.

[0188] Step 2: Entering step 2 indicates that the frequency band of network device B and the frequency band of SIM card 1 (i.e., the frequency band corresponding to the current resident network device corresponding to the second SIM) can no longer maintain the dual-card dual-channel (DSDA) state, and the signal quality of network device B is better than that of network device A. At this time, the signal quality of network device A is returned to be concerned. On the basis of meeting a certain threshold signal quality and a certain percentage of decoding success rate, the terminal device actively lowers the measurement and reporting quality of network device B, thereby sacrificing some acceptable signal quality to avoid triggering the network device to schedule the terminal device to switch to network device B. Maintain network device A with relatively poor signal quality.

[0189] Fig.12 A flow chart of step 2 provided in an embodiment of the present application is as follows: Fig.12 As shown, the method is applied to a terminal device, and step 2 may include S1201 to S1205.

[0190] S1201. Obtain measured signal quality of network device A.

[0191] S1202: Determine whether the signal quality of network device A is greater than a first threshold.

[0192] If the answer to S1202 is yes, proceed to S1203 ; if the answer to S1202 is no, proceed to S1204 .

[0193] S1203: Report a third measurement result obtained by suppressing the measurement result of network device B, where the third measurement result is smaller than the measurement result of network device A.

[0194] S1204: Determine whether the decoding success rate of network device A is greater than the target success rate.

[0195] If the answer to S1204 is yes, proceed to S1205 ; if the answer to S1204 is no, proceed to S1206 .

[0196] S1205: Report a third measurement result obtained by suppressing the measurement result of network device B, where the third measurement result is smaller than the measurement result of network device A.

[0197] S1206. Go to step 3.

[0198] Step 3: Entering step 3 indicates that the signal quality of network device A is not good enough to meet the normal demodulation and decoding of the terminal device. In order to ensure the quality of data transmitted by the terminal device, cell switching can only be triggered. At this time, check whether there is another network device C (corresponding to the fourth cell mentioned above) with the same signal quality as network device B and can be combined with the frequency band of SIM card 0 to meet the radio frequency capability and maintain the dual-card dual-pass state. If such a network device C exists, increase the measurement reporting result of network device C to trigger switching to network device C. If such a network device C does not exist, report the measurement result normally, trigger switching to network device B, and thus be forced to fall back to the dual-card dual-standby (DSDS) state.

[0199] Fig.13 A flow chart of step 3 provided in an embodiment of the present application is as follows: Fig.13 As shown, the method is applied to a terminal device, and step 3 may include S1301 to S1304.

[0200] S1301. Determine that the signal quality of network device A cannot meet the demodulation and decoding requirements.

[0201] S1302: Determine whether there is a signal from network device C with a signal quality comparable to that of network device B.

[0202] In any embodiment of the present application, the signal qualities of the two signals are equivalent, which may include: the absolute value of the difference between the measurement results of the two signals is less than a set threshold.

[0203] If the answer of S1302 is yes, proceed to S1303 ; if the answer of S1302 is no, proceed to S1304 .

[0204] S1303: Increase the measurement result of network device C, thereby triggering a switch to network device C, while maintaining dual-card dual-channel.

[0205] S1304: Report normally.

[0206] The normal reporting of S1304 triggers the switching from network device A to network device B, thereby exiting the dual-card dual-pass state.

[0207] Step 4: If you are currently in the dual-SIM dual-standby (DSDS) state, actively look for other network devices D (corresponding to the fifth cell mentioned above) with the same signal quality as the current network device B. If so, increase the measurement and reporting results of network device D to trigger the switch to network device D as early as possible, thereby switching to the dual-SIM dual-access (DSDA) state.

[0208] In the embodiment of the present application, the dual-card dual-access (DSDA) state can be maintained for as long as possible, which can meet more application scenarios. For example, while one card is surfing the Internet, the other card can still continue to make calls without affecting each other. Although the signal quality within the acceptable range is sacrificed, the richness of the application scenarios is guaranteed.

[0209] In the embodiment of the present application, a method combining measurement of signal quality reporting is used to keep the two SIM cards of the terminal device in a frequency band combination that meets the radio frequency capability as much as possible. It is always preferred to stay in or switch to a frequency band combination that can meet the dual-card dual-pass state, rather than staying in or switching to a cell with the best signal quality. Of course, a certain signal strength and quality must also be guaranteed to avoid excessive decoding errors.
