[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0045] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0046] In related technologies, when a SIM card registers with a network, it typically determines whether to register with a cell based on the relationship between the cell threshold and the signal currently measured by the terminal. This also applies to terminals with dual SIM cards. It's understandable that this registration method considers a relatively limited number of factors and can generally only meet user requirements for network quality.

[0047] However, with the development of technology, people are no longer completely limited to the requirement of network quality, but hope to experience more functional features on the basis of meeting the network quality.

[0048] For example, with the development of dual-SIM dual-pass technology, new features have been brought to terminals, such as simultaneous voice services on both cards, or data services on one card (for example, games or videos) and voice services on another card at the same time. People hope to experience these new features. However, the inventors have found in long-term research that based on cost and platform capabilities, not all frequency combinations corresponding to the main card and the secondary card in the terminal can support the dual-SIM dual-pass function. Therefore, when determining the cell network for registration of the main card and the secondary card based on the signal quality meeting the threshold in the relevant technology, there is a situation where the dual-SIM dual-pass function may not be enabled.

[0049] In view of this, the embodiments of the present disclosure provide a network registration method, device, electronic device, storage medium and chip, which can help the terminal register to the cell corresponding to the dual-SIM dual-pass frequency combination supported by the terminal while ensuring the terminal network quality, so as to meet the user's diverse experience needs.

[0050] Figure 1 FIG. 1 is a flow chart showing a network registration method according to an exemplary embodiment. Figure 1 As shown, the network registration method can be used in a terminal device, such as a mobile phone, a computer, a tablet device, a medical device, a smart watch, etc. The terminal device may include a primary card and a secondary card. The network registration method includes:

[0051] S110, obtain the first cell measurement result and the second cell measurement result, the first cell measurement result includes the first cell searched by the primary card network and the first signal measurement result at the frequency corresponding to the first cell, the second cell measurement result includes the second cell searched by the secondary card network and the second signal measurement result at the frequency corresponding to the second cell.

[0052] Among them, the first cell measurement result can be understood as the cell measurement result obtained by measuring through the primary card network, and the second cell measurement result can be understood as the cell measurement result obtained by measuring through the secondary card network.

[0053] In an embodiment of the present disclosure, the terminal can perform cell measurements through the primary card network and the secondary card network, for example, performing neighboring cell measurements, thereby obtaining a first cell measurement result corresponding to the primary card network, that is, a first cell searched by the primary card network and a first signal measurement result at a frequency corresponding to the first cell, and obtaining a second cell measurement result corresponding to the secondary card network, that is, a second cell searched by the secondary card network and a second signal measurement result at a frequency corresponding to the second cell. In an embodiment of the present disclosure, a cell can be uniquely identified by a cell identifier and a frequency, and therefore, each cell has a corresponding frequency.

[0054] The signal measurement result may be one or more measurement results characterizing signal quality. Optionally, the signal measurement result may be a measurement result of a signal-to-noise ratio (SNR) and / or a measurement result of a reference signal received power (RSRP). For example, in some embodiments, the first signal measurement result may include a measurement result of a signal-to-noise ratio (SNR) and a measurement result of a reference signal received power (RSRP), and the second signal measurement result may include a measurement result of a signal-to-noise ratio (SNR) and a measurement result of a reference signal received power (RSRP).

[0055] In some implementations, in order not to affect the currently ongoing terminal services, the terminal may perform cell measurement when the primary card or the secondary card is in an idle state, i.e., an IDLE state. For example, the cell measurement may be performed when the terminal is in a screen-off state, thereby obtaining a first cell measurement result and a second cell measurement result.

[0056] S120, from the first cell and the second cell, select a first target cell and a second target cell whose signal measurement results meet the preset threshold and whose corresponding frequencies constitute the frequency combination of dual-SIM dual-pass supported by the terminal, wherein the first target cell is a cell in the first cell, and the second target cell is a cell in the second cell. The first target cell is used to indicate the primary card network for registration, and the second target cell is used to indicate the secondary card network for registration.

[0057] In the disclosed embodiment, a first target cell and a second target cell can be selected from the first cell and the second cell, whose signal measurement results meet a preset threshold and whose corresponding frequencies constitute a frequency combination of dual-SIM dual-pass supported by the terminal. Thus, the terminal can subsequently instruct the primary card network to register with the first target cell and instruct the secondary card network to register with the second target cell. Since the frequencies corresponding to the first target cell and the frequencies corresponding to the second target cell constitute a frequency combination of dual-SIM dual-pass supported by the terminal, subsequent registration of the primary card network with the first target cell and the secondary card network with the second target cell facilitates enabling the dual-SIM dual-pass function on the terminal.

[0058] It can be understood that since network quality is the main guarantee for terminal services, in the embodiment of the present disclosure, the signal measurement results at the corresponding frequency points of the first target cell and the second target cell both meet the preset thresholds to ensure that the main card network and the secondary card network can meet the network quality requirements after registering to the corresponding cells.

[0059] Using the above method, after obtaining the measurement results of the first cell and the second cell, the first target cell and the second target cell can be selected from the first cell and the second cell, whose signal measurement results meet the preset threshold and the corresponding frequency points constitute the frequency combination of dual-card dual-pass supported by the terminal. Since the signal measurement results of the first target cell and the second target cell on the corresponding frequency points both meet the preset threshold, and the frequency points corresponding to the first target cell and the frequency points corresponding to the second target cell constitute the frequency combination of dual-card dual-pass supported by the terminal, the terminal can, under the premise of ensuring network quality, enable the primary card network and the secondary card network to be registered to the cell corresponding to the frequency combination of dual-card dual-pass supported by the terminal, so as to meet the diverse experience needs of users.

[0060] In addition, combined with the foregoing content, it can be seen that since network quality is the main guarantee of terminal services, in the embodiment of the present disclosure, the signal measurement results at the corresponding frequency points of the first target cell and the second target cell need to meet the preset threshold to ensure that the primary card network and the secondary card network can meet the network quality requirements after registering with the corresponding cell. In this case, in order to ensure that the signal measurement results at the corresponding frequency points of the first target cell and the second target cell meet the preset threshold, step S120 may include the following steps:

[0061] Based on the preset threshold, a third candidate cell whose signal measurement result meets the preset threshold is determined from the first cell, and a fourth candidate cell whose signal measurement result meets the preset threshold is determined from the second cell.

[0062] From the third candidate cell and the fourth candidate cell, corresponding frequencies are selected to constitute a first target cell and a second target cell of a frequency combination of dual-SIM dual-channel supported by the terminal.

[0063] It can be understood that the first cell may include the service cell of the main card and the neighboring cell that the main card can search, and the second cell may include the service cell of the secondary card and the neighboring cell that the secondary card can search. Then, in order to ensure that the cells included in the candidate cell combination determined subsequently meet the network quality requirements, after obtaining the first cell measurement result and the second cell measurement result, the first cell and the second cell can be screened based on the preset threshold, and a third candidate cell with a signal measurement result greater than the preset threshold is screened from the first cell, and a fourth candidate cell with a signal measurement result greater than the preset threshold is screened from the second cell. Thus, the candidate cell combination is further determined from the screened third candidate cell and the fourth candidate cell, and the target cell combination is determined from the candidate cell combination. In this way, the signal measurement results of the first target cell and the second target cell on the corresponding frequency points each meet the preset threshold.

[0064] In addition, in addition to first screening the first cell and the second cell based on a preset threshold to obtain a third candidate cell and a fourth candidate cell, and then determining the first target cell and the second target cell from the third candidate cell and the fourth candidate cell, in other embodiments, a cell combination whose corresponding frequency combination meets the frequency combination of dual-SIM dual-pass supported by the terminal can be first determined from the first cell and the second cell, and then the cell combination is screened based on the preset threshold to obtain a cell combination including the first target cell and the second target cell, thereby obtaining the first target cell and the second target cell. In this way, the signal measurement results at the corresponding frequencies of the first target cell and the second target cell each meet the preset threshold.

[0065] Furthermore, considering that in some situations, such as power saving mode, a user may not want to enable the dual-SIM dual-active function, in some embodiments, the terminal may obtain the first cell measurement result and the second cell measurement result when determining that the dual-SIM dual-active function is enabled. Alternatively, the terminal may determine that the dual-SIM dual-active function is enabled in response to a user input instruction indicating that the dual-SIM dual-active function is enabled.

[0066] In some implementations, the terminal may detect whether it supports the dual-SIM dual-channel function, and when detecting that it supports the dual-SIM dual-channel function, obtain the frequency combination of the dual-SIM dual-channel supported by the terminal.

[0067] In some embodiments, selecting, from the first cell and the second cell, a first target cell and a second target cell whose signal measurement results meet a preset threshold and whose corresponding frequencies constitute a frequency combination of dual-SIM dual-pass supported by the terminal may include the following steps:

[0068] Screening the cell combination consisting of the first cell and the second cell to determine a candidate cell combination whose corresponding signal measurement result meets a preset threshold and whose corresponding frequency combination meets the frequency combination of dual-SIM dual-channel supported by the terminal;

[0069] A target cell combination is determined from the candidate cell combination, where the target cell combination includes a first target cell and a second target cell.

[0070] In an embodiment of the present disclosure, after obtaining the first cell and the second cell, the terminal can screen the cell combination composed of the first cell and the second cell, determine the candidate cell combination whose corresponding signal measurement result meets the preset threshold and the corresponding frequency combination meets the frequency combination of the dual-card dual-pass supported by the terminal, and then determine the target cell combination including the first target cell and the second target cell from the candidate cell combination.

[0071] It should be noted that in the disclosed embodiment, the cell combination consisting of the first cell and the second cell may be a cell combination that can be formed by all the first cells and all the second cells. In this case, the cell combination may continue to be judged as to whether it meets the preset threshold. Furthermore, the cell combination consisting of the first cell and the second cell may also be a cell combination that can be formed by the third candidate cell and the fourth candidate cell obtained through screening.

[0072] In the following, an exemplary description is given by taking as an example that a cell combination composed of first cells and second cells is a cell combination that can be formed by all first cells and all second cells.

[0073] Assuming that the cells searched by the main card include cell 1 with frequency N41, and the cells searched by the secondary card include cell 2 with frequency B1, cell 3 with frequency B3, and cell 4 with frequency B8, then the frequency combinations include N41+B1, N41+B3, and N41+B8, where the cell combination corresponding to the frequency combination N41+B1 is cell 1+cell 2, the cell combination corresponding to the frequency combination N41+B3 is cell 1+cell 3, and the cell combination corresponding to the frequency combination N41+B8 is cell 1+cell 4. Assuming that the frequency combinations of dual-card dual-pass supported by the terminal are N41+B1 and N41+B8, and the signal measurement results corresponding to the cells included in cell 1+cell 2 and cell 1+cell 4 all meet the preset threshold, that is, the signal measurement results corresponding to cell 1, cell 2, and cell 4 all meet the preset threshold, then cell 1+cell 2 and cell 1+cell 4 can be determined as candidate cell combinations, and then the target cell combination can be determined from the two candidate cell combinations.

[0074] There are multiple ways to determine the target cell combination from the candidate cell combination.

[0075] In some embodiments, considering that the frequency combination of dual-card dual-channel can correspond to multiple types of dual-card dual-channel modes, for example, it can correspond to a dual-card dual-channel mode in which the primary card and the secondary card each occupy a transmitting antenna, that is, a full concurency mode, and a dual-card dual-channel mode in which the primary card and the secondary card reuse one transmitting antenna, that is, a txsharing mode, and the performance of different dual-card dual-channel modes is different. For example, the performance of the full concurency mode is better than the txsharing mode. Therefore, considering the performance difference of the dual-card dual-channel mode, different priorities can be set for different dual-card dual-channel modes. In this case, in order to enable the terminal to enable different dual-card dual-channel function performance, determining the target cell combination from the candidate cell combination may include the following steps:

[0076] Determine whether there is a first candidate cell combination in the candidate cell combination, where the frequency combination corresponding to the first candidate cell combination is a first-priority dual-SIM dual-channel frequency combination supported by the terminal;

[0077] When it is determined that the first candidate cell combination exists in the candidate cell combination, the target cell combination is determined from the first candidate cell combination.

[0078] In the embodiment of the present disclosure, it can be determined from the candidate cell combination whether there is a cell combination whose corresponding frequency combination is the first priority dual-card dual-pass frequency combination supported by the terminal, that is, the first candidate cell combination. If the first candidate cell combination exists, the target cell combination can be determined preferentially from the first candidate cell.

[0079] In some implementations, the first priority for dual-SIM dual-access is a dual-SIM dual-access mode in which the primary and secondary cards each occupy a separate transmit antenna, while the second priority for dual-SIM dual-access is a dual-SIM dual-access mode in which the primary and secondary cards each share a single transmit antenna. In this case, prioritizing the dual-SIM dual-access mode in which the primary and secondary cards each occupy a separate transmit antenna can improve the performance of the dual-SIM dual-access function enabled on the terminal.

[0080] In addition, considering that the number of first candidate cell combinations in the candidate cell combination may be one or more, when the number of first candidate cell combinations is one or more, the manner of determining the target cell combination from the first candidate cell combination may be different.

[0081] Therefore, in some implementations, determining the target cell combination from the first candidate cell combination may include the following steps:

[0082] When the number of the first candidate cell combination is 1, determining the first candidate cell combination as the target cell combination;

[0083] When the number of first candidate cell combinations is greater than 1, a cell combination with the highest priority of the radio access network type corresponding to the primary card and the secondary card is determined from each first candidate cell combination as the target cell combination.

[0084] In the embodiment of the present disclosure, when the number of the first candidate cell combination is 1, the first candidate cell combination can be directly determined as the target cell combination.

[0085] When the number of first candidate cell combinations is greater than 1, the selection can be further made based on the wireless access network type priority of the main card and the secondary card, and the cell combination with the highest wireless access network type priority corresponding to the main card and the secondary card is selected as the target cell combination.

[0086] Among them, the wireless access network type can be, for example, different access network types such as SA (independent networking mode in 5G network) access network, 4G access network, 3G access network and 2G access network.

[0087] For example, in some cases where network speed is pursued, the priorities of 5G access network, 4G access network, 3G access network and 2G access network can be set in descending order. In this case, it is assumed that the frequency combinations corresponding to the first candidate cell combination include N41+B1 and N41+N78, where N41 and N78 are the frequencies of the 5G access network, and B1 is the frequency of the 4G access network. In this case, since N41+N78 are both frequencies corresponding to the 5G access network, the corresponding priority is higher, so the cell combination corresponding to the N41+N78 frequency combination in the first candidate cell combination can be determined as the target cell combination.

[0088] For example, in other situations where both power saving and network speed are a priority, and considering that 4G can also meet normal business needs and 4G can be more power-efficient than 5G in certain situations, in this case, the priorities of the 4G access network, 5G access network, 3G access network, and 2G access network can be set in descending order. Thus, assuming that the frequency combinations corresponding to the first candidate cell combination still include N41+B1 and N41+N78, the cell combination corresponding to the N41+B1 frequency combination in the first candidate cell combination can be determined as the target cell combination.

[0089] In addition, in some cases, there may be two first candidate cell combinations with equal access network type priority. For example, it is assumed that the cell combinations corresponding to the two frequency combinations N41+B1 and B40+N78 are these two first candidate cell combinations, each of which is one 5G access network and one 4G access network.

[0090] In this case, optionally, a first candidate cell combination can be randomly selected as the target cell combination; optionally, it can also be determined based on the recorded user usage habits of the main card and the secondary card. For example, the main card usually performs services that require a higher network speed, while the secondary card usually performs services that require a relatively lower network speed. In this case, it can be determined that the main card uses an access network with a faster network speed, and the secondary card uses an access network with a relatively lower network speed, that is, the first candidate cell combination corresponding to the N41+B1 frequency combination can be selected as the target cell combination; optionally, two first candidate cell combinations with equal priority can be prompted for the user to choose, so that the target cell combination is determined according to the user's choice.

[0091] In combination with the foregoing, it can be seen that in some implementations, when determining whether the first candidate cell combination exists in the candidate cell combination, a situation may occur where the first candidate cell combination does not exist in the candidate cell combination. In this case, the network registration method of the embodiment of the present disclosure may further include the following steps:

[0092] When it is determined that the first candidate cell combination does not exist in the candidate cell combination, determining whether a second candidate cell combination exists in the candidate cell combination, where the frequency combination corresponding to the second candidate cell combination is a frequency combination of dual-SIM dual-channel with a second priority supported by the terminal;

[0093] When it is determined that the second candidate cell combination exists in the candidate cell combination, the target cell combination is determined from the second candidate cell combination.

[0094] In the embodiment of the present disclosure, if there is no first candidate cell combination, the target cell combination may be determined from the second candidate cell combination included in the candidate cell combination.

[0095] Exemplarily, when the frequency combination of dual-card dual-channel includes two types of dual-card dual-channel modes, for example, the first-priority dual-card dual-channel is a dual-card dual-channel mode in which the main card and the secondary card each occupy a transmitting antenna, and the second-priority dual-card dual-channel is a dual-card dual-channel mode in which the main card and the secondary card reuse one transmitting antenna, in this case, if the candidate cell combination does not include the cell combination of the first priority, the target cell combination can be determined from the cell combination of the second-priority dual-card dual-channel frequency combination supported by the terminal for the corresponding frequency combination, that is, the second candidate cell combination.

[0096] Similarly, considering that the number of second candidate cell combinations in the candidate cell combination may be one or more, and the number of first candidate cell combinations may be one or more, the method of determining the target cell combination from the first candidate cell combination may also be different.

[0097] Therefore, in some implementations, determining the target cell combination from the second candidate cell combination may include the following steps:

[0098] When the number of the second candidate cell combinations is 1, determining the second candidate cell combination as the target cell combination;

[0099] When the number of the second candidate cell combinations is greater than 1, the cell combination with the highest priority of the radio access network type corresponding to the primary card and the secondary card is determined from the second candidate cell combinations as the target cell combination.

[0100] In the embodiment of the present disclosure, when the number of the second candidate cell combinations is 1, the second candidate cell combination can be directly determined as the target cell combination.

[0101] When the number of first candidate cell combinations is greater than 1, the selection can be further made based on the wireless access network type priority of the main card and the secondary card, and the cell combination with the highest wireless access network type priority corresponding to the main card and the secondary card is selected as the target cell combination.

[0102] Among them, the method for setting the wireless access network type priority of the main card and the secondary card can refer to the above embodiment and will not be repeated here.

[0103] In addition, in some cases, there may be two second candidate cell combinations with equal access network type priority. In this case, optionally, a second candidate cell combination can be randomly selected as the target cell combination; optionally, it can also be determined based on the recorded user's usage habits for the main card and the secondary card. See the description of the aforementioned embodiment for details, and no further examples will be given here; optionally, two first candidate cell combinations with equal priority can also be prompted for the user to choose, so that the target cell combination is determined according to the user's choice.

[0104] It should be noted that, in the aforementioned embodiment, the performance difference of the dual-SIM dual-communication mode is given priority to determine the target cell combination from the candidate cell combination.

[0105] In addition, in some embodiments, the candidate cell combination may include a first candidate cell combination and a second candidate cell combination, the frequency combination corresponding to the first candidate cell combination is a frequency combination of dual-card dual-pass with a first priority supported by the terminal, and the frequency combination corresponding to the second candidate cell combination is a frequency combination of dual-card dual-pass with a second priority supported by the terminal. In this case, in addition to meeting the basic requirements of the dual-card dual-pass mode, the target cell combination may also be determined from the candidate cell combination in combination with some actual needs. For example, it may be a network rate requirement, or another example may be a comprehensive requirement of power saving and network rate. Therefore, in order to meet the actual usage needs of the user, determining the target cell combination from the candidate cell combination may include the following steps:

[0106] From the first candidate cell combination and the second candidate cell combination, a cell combination with the highest priority of the radio access network type corresponding to the primary card and the secondary card is determined as the target cell combination.

[0107] In the embodiment of the present disclosure, both the first candidate cell combination and the second candidate cell combination can meet the basic dual-card dual-pass function. Therefore, the wireless access network type priority of the main card and the secondary card can be set in combination with the actual usage needs of the user, so that the cell combination with the highest wireless access network type priority corresponding to the main card and the secondary card is used as the target cell combination.

[0108] Among them, the method for setting the wireless access network type priority of the main card and the secondary card can refer to the above embodiment and will not be repeated here.

[0109] For the above implementation, please refer to Figure 2 , Figure 2 is a flow chart showing another network registration method according to an exemplary embodiment. Figure 2 As shown, the network registration method can be used in a terminal device, such as a mobile phone, a computer, a tablet device, a medical device, a smart watch, etc. The terminal device may include a primary card and a secondary card. The network registration method includes:

[0110] S210, obtain the first cell measurement result and the second cell measurement result, the first cell measurement result includes the first cell searched by the primary card network and the first signal measurement result at the frequency corresponding to the first cell, the second cell measurement result includes the second cell searched by the secondary card network and the second signal measurement result at the frequency corresponding to the second cell.

[0111] S220 , screening the cell combination consisting of the first cell and the second cell to determine a candidate cell combination whose corresponding signal measurement result meets a preset threshold and whose corresponding frequency combination meets the frequency combination of dual-SIM dual-communication supported by the terminal.

[0112] S230: Determine whether a first candidate cell combination exists in the candidate cell combination, where the frequency combination corresponding to the first candidate cell combination is a first-priority dual-SIM dual-communication frequency combination supported by the terminal.

[0113] S240: When it is determined that the first candidate cell combination exists in the candidate cell combination, determine a target cell combination from the first candidate cell combination, where the target cell combination includes the first target cell and the second target cell.

[0114] The detailed description of steps S210-S240 can refer to the aforementioned embodiment and will not be repeated here.

[0115] In addition, again corresponding to the above implementation, please refer to Figure 3 , Figure 3 is a flow chart showing another network registration method according to an exemplary embodiment. Figure 3 As shown, the network registration method can be used in a terminal device, such as a mobile phone, a computer, a tablet device, a medical device, a smart watch, etc. The terminal device may include a primary card and a secondary card. The network registration method includes:

[0116] S310, obtain the first cell measurement result and the second cell measurement result, the first cell measurement result includes the first cell searched by the primary card network and the first signal measurement result at the frequency corresponding to the first cell, the second cell measurement result includes the second cell searched by the secondary card network and the second signal measurement result at the frequency corresponding to the second cell.

[0117] S320: Screen the cell combination consisting of the first cell and the second cell to determine a candidate cell combination whose corresponding signal measurement result meets a preset threshold and whose corresponding frequency combination meets the frequency combination of dual-SIM dual-channel supported by the terminal, where the candidate cell combination includes the first candidate cell combination and the second candidate cell combination.

[0118] Among them, the frequency combination corresponding to the first candidate cell combination is the first priority dual-SIM dual-channel frequency combination supported by the terminal, and the frequency combination corresponding to the second candidate cell combination is the second priority dual-SIM dual-channel frequency combination supported by the terminal.

[0119] S330: Determine, from the first candidate cell combination and the second candidate cell combination, a cell combination with the highest priority of the radio access network type corresponding to the primary card and the secondary card as a target cell combination, wherein the target cell combination includes the first target cell and the second target cell.

[0120] The detailed description of steps S310-S330 can refer to the above embodiment and will not be repeated here.

[0121] It should be noted that the main card and the secondary card in the embodiment of the present disclosure do not impose specific location restrictions on the SIM card included in the terminal. They are only used to distinguish different SIM cards. They can correspond to the names of the main card and the secondary card marked in the terminal card slot, or they can be different from the names of the main card and the secondary card marked in the terminal card slot.

[0122] The following uses a complete network registration scenario as an example to illustrate the network registration method of the embodiment of the present disclosure. In the embodiment of the present disclosure, dual-SIM dual-pass can specifically include a dual-SIM dual-pass mode in which the primary card and the secondary card each occupy a separate transmitting antenna, and a dual-SIM dual-pass mode in which the primary card and the secondary card reuse a single transmitting antenna. The terminal can detect whether it supports dual-SIM dual-pass mode. If it determines that it supports dual-SIM dual-pass mode and detects that dual-SIM dual-pass mode is enabled, it can execute the network registration method of the embodiment of the present disclosure.

[0123] When the terminal determines that it is in a black screen waiting state, for example, it obtains the first cell measurement result and the second cell measurement result.

[0124] Then, based on the preset threshold, the terminal can determine a third candidate cell from the first cell whose signal measurement result at the corresponding frequency point meets the preset threshold, and determine a fourth candidate cell from the second cell whose signal measurement result at the corresponding frequency point meets the preset threshold.

[0125] Then, the terminal may group the third candidate cell and the fourth candidate cell into a cell combination, wherein each cell combination corresponds to a frequency combination.

[0126] Next, the terminal can match the frequency combination corresponding to the cell combination with the frequency combination of the first-priority dual-card dual-pass supported by itself to see whether there is a first candidate cell combination corresponding to the frequency combination of the first-priority dual-card dual-pass in the cell combination. If so, and the number is 1, then the first candidate cell combination is directly determined as the target cell combination. If so, and the number is greater than 1, then from each first candidate cell combination, the cell combination with the highest priority of the radio access network type corresponding to the primary card and the secondary card is determined as the target cell combination. Here, the radio access network type priority can be set according to the network rate requirement, or according to the comprehensive requirements of power saving and network rate. Please refer to the above embodiment for details.

[0127] If the first candidate cell combination does not exist in the cell combination, the number of remaining second candidate cell combinations in the cell combination is considered. If the number of second candidate cell combinations is 1, the second candidate cell combination is directly determined as the target cell combination. If the number of second candidate cell combinations is greater than 1, the cell combination with the highest radio access network type priority corresponding to the primary card and the secondary card is determined from each second candidate cell combination as the target cell combination. Here, the radio access network type priority can be set based on the network speed requirement, or based on the combined requirements of power saving and network speed. Please refer to the above embodiment for details.

[0128] It can be understood that after the target cell combination is determined through the above process, the terminal can register the primary card network to the first target cell included in the target cell combination, and register the secondary card network to the second target cell included in the target cell combination, thereby further enabling the dual-card dual-pass function.
