At present, two sets of receiving and transmitting radio frequencies are generally required to be configured in the electronic equipment to realize the dual-card dual-standby dual-pass technology, but limited receiving and transmitting radio frequency antennas can support dual-card dual-standby dual-pass of partial dual-card frequency band combination due to the limitation of hardware cost and the size of the electronic equipment.
However, when the electronic device involves cell switching during the mobile process and the calling card 1 is in a call state, the calling card 2 in a non-call state generally randomly selects an adjacent cell to switch, and after the calling card 2 completes cell switching, the calling card 1 and the calling card 2 may not support dual-card dual-pass any more, which results in lower residence probability of the calling card 1 and the calling card 2 in the cell supporting dual-card dual-pass, and further results in interruption risk of ongoing data service of the calling card 2.

All other embodiments, which are derived by a person skilled in the art based on the embodiments herein, are intended to be within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes a cell handover method provided in the embodiment of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 illustrates a flowchart of a cell handover method provided by some embodiments of the present application. In an embodiment of the present application, the method may include:
step 110: and under the condition that the first call card is in a call state, the second call card is in a non-call state, and the first cell accessed by the second call card accords with a preset cell switching condition, determining a first target cell from at least one adjacent cell based on the priority of the frequency band combination of the at least one adjacent cell of the second call card.
Specifically, step 110 is configured to determine, when the first calling card is in a calling state and the second calling card is in a non-calling state, and the first cell accessed by the second calling card meets a preset cell switching condition, a first target cell to which the second calling card can be switched. Further, the first target cell determined in step 110 is the basis for switching the cell accessed by the second communication card to the first target cell in step 120.
In some embodiments of the present application, the cell handover method may be applied to a terminal device, where the terminal device may be a UE device (User Equipment), and the terminal device may be a terminal device supporting dual cards or a terminal device supporting multiple cards. The terminal device is a terminal device supporting dual cards, when one calling card in the terminal device is in a calling state through active calling or answering, the other calling card is in a non-calling state, and a cell accessed by the calling card in the non-calling state accords with a preset cell switching condition, a first target cell is determined from at least one adjacent cell based on the priority of the frequency band combination of the at least one adjacent cell of the calling card.
The first call card and the second call card include, but are not limited to, a physical SIM card and a virtual SIM card. Specifically, the physical SIM card is an application smart card in a GSM (Global System for Mobile Communication, global system for mobile communications) system, the physical SIM card is separated from the terminal device, one SIM card corresponds to one client, and the physical SIM card may include standard cards and MicroSIM, nanoSIM; the virtual SIM card is integrated in the terminal equipment, and a novel SIM card adopting an embedded technology (e-SIM) can enable the terminal equipment such as a mobile phone and the like to be switched among different operator networks.
It should be noted that, the preset cell switching condition may be set based on cell switching condition information carried in an RRC (Radio Resource Control ) reconfiguration message issued by the network device, and according to different working scenario needs, the preset cell switching condition may include at least one of the following: determining according to the carrier level of the received signal, and when the carrier level of the signal is lower than a threshold level, meeting the preset cell switching condition, wherein the threshold level can be-100 dBm (power unit: decibel milliwatt) by way of example; judging according to the carrier-to-interference ratio of the received signal, and conforming to a preset cell switching condition when the carrier-to-interference ratio is lower than a given carrier-to-interference ratio of the measurement configuration information; and judging according to the distance from the terminal equipment to the cell base station, and conforming to the preset cell switching condition when the distance is larger than the given distance value of the measurement configuration information.
Of course, the setting of the preset cell switching condition may also be performed manually according to the actual working scenario and measurement configuration information issued by the network device, for example, the preset cell switching condition may be set manually to perform cell switching when the signal quality of the neighboring cell is higher than the signal quality of the first cell currently accessed by the second communication card. The embodiment of the present application is not particularly limited thereto.
The network device may be a cell base station controller or a core network controller; specifically, when the first call card needs to perform cell switching across the core network, the cell information of the adjacent cells needs to be reported to the core network controller, and the core network controller controls the first call card to perform cell switching; when the first call card does not need to perform cell switching across the core network, the cell information of the adjacent cell can be reported to the base station management controller of the second cell which is accessed currently, and the base station management controller controls the first call card to perform cell switching.
In some embodiments of the present application, the neighboring cell of the second session card may be a neighboring cell in a measurement neighboring cell list carried in an RRC reconfiguration message issued by the network device.
It should be noted that, when the first calling card is in a call state by actively calling or answering an incoming call and the second calling card is in an RRC connection state, the second calling card may acquire an RRC reconfiguration message issued by the network device. The RRC reconfiguration message may carry measurement configuration information such as a measurement ID, a measurement neighbor list, cell handover condition information, a measurement report amount, and a measurement report mode.
In some embodiments of the present application, before performing step 110, the first calling card and the second calling card of the terminal device may also be respectively registered in an NR (New Radio, new air interface) network or an LTE (Long Term Evolution ) network. The operation of the terminal device that the first calling card and the second calling card register with the NR network or the LTE network may be performed when the terminal device is turned on. The first call card and the second call card of the terminal device can realize the call function and the data network use after registering the NR network or the LTE network. Specifically, the NR network may be a 5G (5 th-Generation Mobile Communication Technology, fifth generation mobile communication technology) network, and the LTE network may be a 4G (4 th-Generation Mobile Communication Technology, fourth generation mobile communication technology) network.
It should be noted that, after the terminal device registers the NR network or the LTE network, the frequency band combination formed by the frequency band of the second cell accessed by the first call card and the frequency band of the first cell accessed by the second call card in the terminal device may be a frequency band combination supporting DSDA, or may be a frequency band combination not supporting dual-card dual-pass.
In some embodiments of the present application, the priority of the frequency band combination based on the at least one neighboring cell of the second calling card may specifically be a priority of the frequency band combination based on the frequency band of the at least one neighboring cell of the second calling card and the frequency band of the second cell to which the first calling card is connected. The priority may be a priority determined based on the case that the band combination supports dual-card dual-pass, for example, the priority of the band combination supporting dual-card dual-pass is higher than the priority of the band combination not supporting dual-card dual-pass.
It should be noted that, when the number of the first target cells is 1, step 120 may be directly performed to switch the cell accessed by the second communication card to the first target cell. The frequency band combination formed by the frequency band of the first target cell and the frequency band of the second cell accessed by the first call card supports double-card double-pass.
Furthermore, after step 110, before step 120, the method may further comprise: measuring adjacent cells corresponding to a first target cell, acquiring cell information of the first target cell, and sending the cell information to network equipment under the condition that the cell information accords with reporting conditions; and after receiving the cell indication information corresponding to the first target cell sent by the network device, performing step 120 of switching the cell accessed by the second communication card to the first target cell based on the cell indication information.
Step 120: and switching the cell accessed by the second communication card into the first target cell.
Specifically, after determining the first target cell from the at least one neighboring cell based on the priority of the frequency band combination of the at least one neighboring cell of the second communication card in step 110, the cell accessed by the second communication card may be switched to the first target cell determined in step 110 through step 120.
In some embodiments of the present application, in the case that the number of the first target cells is 1, the first cell to which the second communication card is connected may be directly switched to the first target cell. After the cell accessed by the second calling card is switched, the frequency band combination consisting of the frequency band of the second cell accessed by the first calling card and the frequency band of the first cell accessed by the second calling card is ensured to support double-card double-pass, thereby ensuring the normal use of the data network of the second calling card and the use of the function of normally carrying out active calling or answering incoming calls while ensuring the voice quality of the first calling card.
When the terminal device carried by the user is in a mobile state, the first call card of the terminal device is in a call state, and the second call card is in a non-call state, for example, when the user is in a mobile state in a call state through the first call card in the terminal device in a process of taking the vehicle, and when the first cell currently accessed by the first call card meets a preset cell switching condition due to the mobile state of the current terminal device, the first call card can measure at least one neighboring cell based on measurement configuration information in the RRC reconfiguration message to obtain cell information of the at least one neighboring cell, report the cell state information to the network device, determine a second target cell to be switched by the first call card according to the cell information of the neighboring cell, and control the first call card to switch the currently accessed cell to the second target cell by sending cell indication information to the first call card. Thereby ensuring the call quality of the first call card in the current call state; and simultaneously, after the first call card is subjected to cell switching, determining a first target cell from at least one adjacent cell based on the priority of the frequency band combination of at least one adjacent cell of the second call card under the condition that the first cell accessed by the second call card meets the preset cell switching condition, and switching the cell accessed by the second call card into the first target cell. Therefore, after the second call card in the non-call state is switched between the cells, the frequency band combination formed by the frequency band of the second cell accessed by the first call card and the frequency band of the first target cell accessed by the second call card still supports double-card double-pass, and further, when the call quality of the first call card in the call state is not influenced, the data service of the second call card in progress is not interrupted, and the residence probability of the first call card and the second call card installed in the terminal equipment in the cell supporting double-card double-pass is improved.
Referring to fig. 2, fig. 2 illustrates a flow chart of a cell handover method provided by some embodiments of the present application. In an embodiment of the present application, the method may include:
step 210: and under the condition that the first call card is in a call state, the second call card is in a non-call state, and the first cell accessed by the second call card accords with a preset cell switching condition, determining the priority of the frequency band combination of each adjacent cell based on the frequency band combination in the corresponding relation between the first frequency band combination of the adjacent cell and the target for each adjacent cell of the second call card.
Specifically, step 210 is configured to determine, when the first calling card is in a calling state, the second calling card is in a non-calling state, and the first cell accessed by the second calling card meets a preset cell switching condition, based on a frequency band combination in a corresponding relation between a first frequency band combination of each neighboring cell of the second calling card and a target frequency band, determine a priority of the frequency band combination of each neighboring cell, and provide a determination basis for determining, in step 220, from the neighboring cells, a first target cell based on the priority of the frequency band combination of each neighboring cell.
The frequency band combination of the adjacent cell is a frequency band combination consisting of the frequency band of the adjacent cell and the frequency band of the second cell; the target correspondence includes a correspondence between a combination of frequency bands and a priority.
It should be noted that, the correspondence between the frequency band combination priorities in the target correspondence may be a one-to-one correspondence, and according to any frequency band combination in the target correspondence, a priority corresponding to the frequency band combination may be determined. It should be noted that, different frequency band combinations in the target correspondence may correspond to different priorities or may correspond to the same priority, but based on a determined first frequency band combination, a determined priority corresponding to the first frequency band combination may be determined.
In some embodiments of the present application, a correspondence between a frequency band combination in a target correspondence and a priority may be stored in a table form, and based on a first frequency band combination of a neighboring cell, a priority corresponding to the frequency band combination corresponding to the first frequency band combination in the target correspondence is queried from the table, and the queried priority is determined as the priority of the first frequency band combination.
The terminal device may include a first calling card and a second calling card, and based on the hardware capability of the terminal device and the configuration condition of the radio frequency driver, the terminal device can only support the combination of frequency bands corresponding to the NR cell+nr cell, and the NR cell+lte cell. Referring to table 1, table 1 shows preset frequency band combinations corresponding to NR cells+nr cells set according to hardware capabilities of terminal devices and configuration situations of radio frequency driving.

Referring to table 2, table 2 shows preset frequency band combinations corresponding to NR cells+lte cells set according to hardware capabilities of terminal devices and configuration situations of radio frequency driving.

Illustratively, the terminal device hardware and radio frequency driven DSDA capabilities are configured to: the first frequency band of the second cell accessed by the first call card in the terminal equipment is N78, and the second frequency band of the first cell accessed by the second call card is N41, so that the frequency band combination of the first frequency band and the second frequency band is N78+N41; and the carrier of the first call card is China Unicom or China telecom, the frequency bands supported by the carrier are N78 and N1, the carrier of the second call card is China Mobile, and the frequency bands supported by the carrier are N41, N79 and N28. When the first call card is in a call state and the second call card is in a non-call state, and the first cell accessed by the second call card meets the preset cell switching condition, the first frequency band of the second cell accessed by the first call card is N78, and the frequency bands of the adjacent cells of the second call card comprise N1, N41, N78, N28, B1 (uplink frequency: 1920MHz-1980MHz, downlink frequency: 2110MHz-2170 MHz), B3 (uplink frequency: 1710MHz-1785MHz, downlink frequency: 1805MHz-1880 MHz), B38 (frequency: 2570MHz-2620 MHz), and B39 (frequency: 1880MHz-1920 MHz).
Wherein N1, N41, N78 and N28 are 5G frequency bands, and B1, B3, B38 and B39 are 4G frequency bands; and N41 and N28 are frequency bands supported by an operator to which the second communication card belongs.
Based on the above information, the priority of the frequency band combination of the adjacent cells of the second calling card may be determined as:
first preset priority: n41 naffcn xx, N28 naffcn yy;
second preset priority: b1 EARFCN zz, B3 EARFCN ww;
third preset priority: b38 EARFCN aa, B39 EARFCN bb;
fourth preset priority: n1 NARFCN aa, N78 NARFCN dd.
Thus, based on the priority of the combination of the frequency bands of the adjacent cells of the second calling card, the determined first target cell includes, from among the adjacent cells, the adjacent cells having the frequency bands of N41, N28, B1, and B3; because the number of the first target cells is larger than 1, the cell information meeting the reporting condition in the cell information of the adjacent cells with the frequency bands of N41 and N28 can be sent to the network equipment; and then receiving the cell indication information sent by the network equipment, and switching the cell accessed by the second communication card into a first target cell indicated by the cell indication information based on the cell indication information.
Note that NARFCN (NR Absolute Radio Frequency Channel Number) is an absolute frequency number of an NR network, and EARFCN (E-UTRA Absolute Radio Frequency Channel Number) is an absolute frequency number of an LTE network; wherein xx, yy, zz, ww, aa and bb respectively represent different frequency point number information of different neighboring cells.
Illustratively, the terminal device hardware and radio frequency driven DSDA capabilities are configured to: the first frequency band of the second cell accessed by the first call card in the terminal equipment is N41, and the second frequency band of the first cell accessed by the second call card is N78, so that the frequency band combination of the first frequency band and the second frequency band is N41+N78; and the carrier of the first call card is China mobile, the frequency bands supported by the carrier are N41, N79 and N28, the carrier of the second call card is China Unicom or China telecom, and the frequency bands supported by the carrier are N78 and N1. When the first call card is in a call state and the second call card is in a non-call state, and the first cell accessed by the second call card meets the preset cell switching condition, the first frequency band of the second cell accessed by the first call card is N41, and the frequency bands of the adjacent cells of the second call card comprise N1, N41, N78 and N28.
N1, N41, N78 and N28 are 5G frequency bands, and the current adjacent cells are NR cells; and N1 and N78 are frequency bands supported by the operator to which the second communication card belongs.
Based on the above information, the priority of the frequency band combination of the adjacent cells of the second calling card may be determined as:
first preset priority: n78 naffcn xx, N1 naffcn yy;
Fourth preset priority: n28 narfcnb.
Thus, based on the priority of the combination of the frequency bands of the adjacent cells of the second calling card, the determined first target cell includes the adjacent cells with the frequency bands of N78 and N1 from the adjacent cells; because the number of the first target cells is larger than 1, the cell information meeting the reporting condition in the cell information of the adjacent cells with the frequency bands of N78 and N1 can be sent to the network equipment; and then receiving the cell indication information sent by the network equipment, and switching the cell accessed by the second communication card into a first target cell indicated by the cell indication information based on the cell indication information.
Note that NARFCN (NR Absolute Radio Frequency Channel Number) is an absolute frequency number of an NR network, and EARFCN (E-UTRA Absolute Radio Frequency Channel Number) is an absolute frequency number of an LTE network; wherein xx, yy and bb respectively represent different frequency point number information of different adjacent cells.
In some embodiments of the present application, a database including only frequency band combinations supporting dual-card dual-pass may be created according to dual-card dual-pass supporting conditions of the frequency band combinations, where the frequency band combinations in the database are used as the frequency band combinations in the target corresponding relationship, and priorities corresponding to the frequency band combinations in the target corresponding relationship are all first priorities corresponding to the frequency band combinations supporting dual-card dual-pass; of course, the frequency band combination in the database can be further divided into the first priority corresponding to the frequency band combination in the target corresponding relation according to the 5G frequency band combination supporting double-card double-pass and the 4G frequency band combination supporting double-card double-pass: a first preset priority corresponding to a 5G band combination supporting dual-card dual-pass and a second preset priority corresponding to a 4G band combination supporting dual-card dual-pass. Specifically, the priority corresponding to the frequency band combination corresponding to the first frequency band combination in the target corresponding relation can be queried from the database based on the first frequency band combination of the adjacent cell, and the queried priority is determined as the priority of the first frequency band combination.
Illustratively, according to the terminal device hardware and the DSDA capability configuration of the radio frequency driver, a preset database corresponding to the first preset priority and the second preset priority may be generated by combining frequency bands supporting dual-card dual-pass in preset frequency band combinations in table 1 and table 2; specifically, the frequency band combination database of the first preset priority corresponding to the 5G frequency band combination supporting the dual-card dual-pass is { n78+n1, n78+n28,..n41+n1 }, and the frequency band combination database of the second preset priority corresponding to the 4G frequency band combination supporting the dual-card dual-pass is { n78+b1, n78+b3,...
It should be noted that, the correspondence between the frequency band combination and the priority may be determined based on the function information of the functions that can be implemented by the frequency band combination in the target correspondence. The functions may include, but are not limited to, information such as a dual card bi-pass support case, a dual card bi-standby (DSDS, dual SIM dual standy) support case, an operator support case, etc.; and determining the priority corresponding to the frequency band combination in the target corresponding relation according to the function information. For example, according to the dual-card dual-pass supporting condition in the function information, the frequency band combination in the target corresponding relation can be determined to be the frequency band combination supporting dual-card dual-pass and the frequency band combination not supporting dual-card dual-pass, and the priority corresponding to the frequency band combination can be further determined according to the dual-card dual-pass supporting condition of the frequency band combination. Of course, the correspondence between the frequency combination and the priority in the target correspondence may also be determined according to the support condition of the operator in the function information, which is not specifically limited in the embodiment of the present application.
Optionally, step 210 may include sub-step 2101 and sub-step 2102:
sub-step 2101: and when a second frequency band combination which is the same as the first frequency band combination exists in the target corresponding relation, determining a first priority corresponding to the second frequency band combination as the priority of the frequency band combination of the adjacent cell.
Specifically, in the case where there is a second frequency band combination identical to the first frequency band combination in the target correspondence, the sub-step 2101 may determine the first priority corresponding to the second frequency band combination as the priority of the frequency band combination of the neighboring cell, thereby implementing the determination of the priority of the frequency band combination of the neighboring cell in the case where there is the second frequency band combination identical to the first frequency band combination in the target correspondence.
Sub-step 2102: and if the frequency band combination which is the same as the first frequency band combination does not exist in the target corresponding relation, determining a second priority as the priority of the frequency band combination of the adjacent cell.
The frequency band combination corresponding to the first priority comprises a frequency band combination supporting double-card double-pass, and the frequency band combination corresponding to the second priority comprises a frequency band combination not supporting double-card double-pass.
Specifically, in the sub-step 2102, when the same frequency band combination as the first frequency band combination does not exist in the target correspondence, the second priority is determined as the priority of the frequency band combination of the neighboring cell, so that the determination of the priority of the frequency band combination of the neighboring cell is realized when the same frequency band combination as the first frequency band combination does not exist in the target correspondence.
In some embodiments of the present application, the priority of the frequency band combination of at least one neighboring cell of the second communication card may include a first priority and a second priority, where the frequency band combination corresponding to the first priority includes a frequency band combination supporting dual-card dual-pass, and the frequency band combination corresponding to the second priority includes a frequency band combination not supporting dual-card dual-pass.
In some embodiments of the present application, the frequency band combinations in the target corresponding relationship are frequency band combinations supporting dual-card dual-pass, and priorities corresponding to the frequency band combinations in the target corresponding relationship are all first priorities supporting dual-card dual-pass. Under the condition that a second frequency band combination which is the same as the first frequency band combination exists in the target corresponding relation, the first frequency band combination is indicated to be a frequency band supporting double-card double-pass, so that a first priority corresponding to the second frequency band combination in the target corresponding relation can be determined to be the priority of the frequency band combination of the adjacent cell; similarly, in the case that the same frequency band combination as the first frequency band combination does not exist in the target correspondence relationship, it is indicated that the first frequency band combination is a frequency band combination that does not support dual-card dual-pass, and therefore, the second priority corresponding to the frequency band combination that does not support dual-card dual-pass can be determined as the priority of the neighboring cell.
Thus, the priority corresponding to each neighboring cell of the second communication card can be determined. Specifically, in the case that the frequency band combination of the adjacent cell of the second communication card is a frequency band combination supporting dual-card dual-pass, determining the priority of the frequency band combination of the adjacent cell as a first priority; and determining the priority of the frequency band combination of the adjacent cell as the second priority under the condition that the frequency band combination of the adjacent cell of the second communication card is the frequency band combination which does not support double-card double-pass. Therefore, the priority of the first frequency band combination of the adjacent cells of the second communication card can be determined based on the target corresponding relation, and the priority is divided based on the dual-card dual-pass supporting condition of the frequency band combination, so that the first target cell can be further determined from the adjacent cells based on the priority of the frequency band combination of the adjacent cells of the second communication card determined in the substep 2101 and the substep 2102, so as to ensure that the frequency band combination of the first target cell and the frequency band combination of the second cell accessed by the first communication card supports dual-card dual-pass.
In an exemplary embodiment, under the condition that a dual-card dual-pass is supported by a frequency band combination consisting of a frequency band of a second cell to which the first calling card of the terminal device is currently connected and a frequency band of the first cell to which the second calling card is currently connected, when the first calling card is in a calling state, if a prompt tone is heard by the second calling card, a user can choose to answer or hang up the call of the second calling card, if the user does not choose to answer or hang up the call of the second calling card, a missed call related to the second calling card is displayed after the call is ended; likewise, if the user is playing the network game using the data network of the first calling card, and the second calling card enters the calling state, the data network being used by the first calling card will not be interrupted, and the user is playing the network game and will not be dropped.
Under the condition that a frequency band combination consisting of a frequency band of a second cell which is accessed by a first call card of terminal equipment at present and a frequency band of the first cell which is accessed by the second call card at present supports double-card double-standby, when the first call card is in a call state, if other users call the second call card through other call cards, the other users can receive prompt information about that the current second call card cannot be connected or is not in a service area, and the user cannot hear prompt sound and does not receive an electric prompt at the side of the second call card; likewise, if the first calling card is playing the network game and the second calling card enters the calling state, the data network being used by the first calling card will be interrupted, and the network game being played by the data network using the first calling card will be dropped, which affects the normal handling of related services by the user through the data network of the first calling card.
If the frequency band supported by each operator is different, if the operator acquires the cell information of the adjacent cell in a PLMN (Public Land Mobile Network ) mode, the cell information of the adjacent cell is acquired only if the frequency band of the adjacent cell is the frequency band supported by the operator; and if the frequency band of the adjacent cell is the frequency band which is not supported by the operator, discarding obtaining the cell information of the adjacent cell. For example, the NR frequency bands allocated by the service division to the chinese mobile are N41 (frequency: 2515MHz-2675 MHz), N79 (frequency: 4800MHz-4900 MHz) and N28 (frequency: 758MHz-803 MHz), while the NR frequency bands allocated by the chinese communication and the chinese telecommunication are N78 (chinese communication frequency: 3500MHz-3600MHz, chinese telecommunication frequency: 3400MHz-3500 MHz) and N1 (frequency: 2110MHz-2170 MHz), when the second calling card is a SIM card for the chinese mobile, if there is a frequency band of N78 or N1 in the neighboring cell, at this time, if the first cell to which the second calling card is connected meets the preset cell switching condition, the cell information of the neighboring cell corresponding to the N78 or N1 frequency band will not be acquired.
In some embodiments of the present application, based on the frequency band combination of each of the neighboring cells in the neighboring cells of the second communication card and the frequency band combination of the second cell, the frequency band combination priority of each of the neighboring cells of the second communication card may be determined by a correspondence between the frequency band combination and the priority in the target correspondence, respectively.
Step 220: a first target cell is determined from each neighboring cell based on the priority of the band combination of the neighboring cells.
Specifically, after determining the priority of the frequency band combination of each neighboring cell in step 210, a first target cell may be determined from among the neighboring cells based on the determined priority of the frequency band combination of each neighboring cell in step 210.
In some embodiments of the present application, based on the priority of the frequency band combination of each neighboring cell, a neighboring cell corresponding to a frequency band combination of a higher priority may be determined as the first target cell from among neighboring cells of the second communication card.
Of course, considering the difference of practical application scenarios, the division basis of the priority of the frequency band combination of the adjacent cells may also have a difference, so the reference for determining the first target cell from the adjacent cells may be determined according to the practical needs, which is not specifically limited in the embodiment of the present application.
In some embodiments of the present application, when the first calling card is in a calling state, the second calling card is in a non-calling state, and the first cell accessed by the second calling card meets a preset cell switching condition, for each neighboring cell of the second calling card, the priority of the frequency band combination of each neighboring cell may be determined based on the corresponding relationship between the frequency band combination of the first frequency band combination of the neighboring cell and the target corresponding relationship between the frequency band combination of the frequency band of the neighboring cell and the priority. The target corresponding relation comprises the corresponding relation between the frequency band combination and the priority, and the frequency band combination priority of each adjacent cell of the second communication card can be determined based on the frequency band combination in the first frequency band combination target corresponding relation of the adjacent cells; and then determining a first target cell from the adjacent cells based on the priority of the frequency band combination of each adjacent cell, so that the first target cell can be ensured to be the adjacent cell corresponding to the frequency band combination with higher priority in the adjacent cells of the second communication card, and the determined first target cell is the optimal selection in the adjacent cells of the second communication card.
Optionally, step 220 may include sub-step 2201:
Sub-step 2201: and determining the adjacent cell with the priority of the frequency band combination as the first priority as the first target cell.
Specifically, after sub-step 2101 and sub-step 2102 determine the priority of the band combination of each neighboring cell of the second communication card, neighboring cells having the priority of the band combination of the first priority may be further determined as the first target cell. Because the frequency band combination corresponding to the first priority is the frequency band combination supporting the double-card double-pass, the adjacent cell with the priority of the frequency band combination being the first priority is determined to be the first target cell, the frequency band combination consisting of the frequency band of the first target cell and the frequency band of the second cell accessed by the first call card can be realized to support the double-card double-pass, and further, after the cell accessed by the second call card is switched to the first target cell in step 230, the frequency band combination of the frequency band of the second cell accessed by the first call card and the frequency band combination of the first cell accessed by the second call card is the frequency band combination supporting the double-card double-pass, so that the communication function of the second call can be normally realized while the current call quality of the first call card is ensured.
In some embodiments of the present application, the neighboring cell with the priority of the frequency band combination being the first priority is determined as the first target cell, and the frequency band combination corresponding to the first priority is a frequency band combination supporting dual-card dual-pass. Therefore, the frequency band combination formed by the frequency band of the first target cell and the frequency band of the second cell accessed by the first call card can be ensured to support double-card double-pass.
Optionally, in the case that the number of the first target cells is greater than 1, the cell handover method may further include steps 310 and 320:
step 310: and sending the cell information meeting the reporting condition in the target information to the network equipment.
The frequency band combination corresponding to the first priority comprises a 5G frequency band combination supporting double-card double-pass and a 4G frequency band combination supporting double-card double-pass.
It should be noted that, the 5G frequency band may be a working frequency band corresponding to cell frequency point information of the NR cell; the 4G frequency band can be a working frequency band corresponding to cell frequency point information of the LTE cell; and under the condition that the first cell accessed by the second communication card accords with the preset cell switching condition, the NR adjacent cells in the adjacent cells of the second communication card can be preferentially selected for switching, so that the priority of the 5G frequency band combination supporting double-card double-pass is higher than the priority of the 4G frequency band combination supporting double-card double-pass. Of course, if the NR neighbor cell signal in the neighbor cell of the second calling card is too weak, an attempt may be made to switch the first cell to which the second calling card is connected to an LTE neighbor cell.
Specifically, in the case that the number of the first target cells is greater than 1, the cell information, which meets the reporting condition, of the target information, that is greater than 1 may be sent to the network device through step 310, one first target cell is determined from the cell information, which is greater than 1, through the network device, and the cell indication information about the first target cell is sent to the terminal device in the form of the cell indication information, so that the cell indication information sent by the network device is received in step 320, where the cell indication information is the cell indication information about the first target cell determined by the network device based on the received cell information.
In some embodiments of the present application, in a case where the band combination of the first target cell includes a 5G band combination supporting dual-card dual-pass, the target information is first cell information of a neighboring cell supporting the 5G band combination supporting dual-card dual-pass; under the condition that the target condition is met, the target information is the second cell information of the adjacent cells supporting the double-card double-pass 4G frequency band combination; wherein the target condition includes at least one of: the frequency band combination of the first target cell does not comprise the 5G frequency band combination supporting double-card double-pass, and the first cell information does not comprise the cell information meeting the reporting condition.
The RRC reconfiguration message may further include measurement configuration information of a reporting condition of the cell information, where the reporting condition may include one reporting triggered by a measurement event, periodic reporting, and periodic reporting triggered by the measurement event; in some embodiments of the present application, after the RRC reconfiguration message is acquired, test configuration information about the reporting condition in the RRC reconfiguration message may be acquired, and then the setting of the reporting condition may be performed according to a specific reporting condition in the RRC reconfiguration message issued by the network device.
In some embodiments of the present application, the cell information may include a measurement result of a neighboring cell of the second communication card and a measurement result of a first cell to which the second communication card is currently connected. Before the terminal equipment sends the cell information meeting the reporting condition in the target information to the network equipment, the first target cell needs to be measured first, and the cell information corresponding to the first target cell is acquired. Specifically, under the condition that the frequency band combination of the first target cell comprises a 5G frequency band combination supporting double-card double-pass, firstly measuring a neighboring cell corresponding to the 5G frequency band combination supporting double-card double-pass to acquire cell information of the neighboring cell; and under the condition that the frequency band combination of the first target cell does not comprise the 5G frequency band combination supporting the double-card double-pass or the first cell information does not comprise the cell information conforming to the reporting condition, measuring the adjacent cell corresponding to the 4G frequency band combination supporting the double-card double-pass, and acquiring the cell information of the adjacent cell.
That is, in the case that the band combination of the first target cell includes a 5G band combination supporting dual-card dual-pass, firstly, measuring a neighboring cell corresponding to the 5G band combination supporting dual-card dual-pass, and in the case that the cell information of the neighboring cell accords with the reporting condition, directly transmitting the cell information of the neighboring cell to the network device, without continuing to measure the neighboring cell corresponding to the 4G band combination supporting dual-card dual-pass of the first target cell, and without further measuring neighboring cells other than the first target cell in the neighboring cell of the second communication card; similarly, in the case that the number of the first target cells is 1, only the one first target cell needs to be measured, and measurement of other adjacent cells except the first target cell is not needed. Therefore, after the cell accessed by the second communication card is ensured to be switched to the first target cell, the frequency band combination formed by the frequency band of the second cell accessed by the first communication card and the frequency band of the first cell accessed by the second communication card is the frequency band combination supporting double-card double-pass, and meanwhile, the directivity and the destination of the cell information acquisition of the adjacent cells of the second communication card can be improved, and meanwhile, the cell information of all the adjacent cells is prevented from being acquired simultaneously, so that the power consumption expense of the terminal equipment can be reduced.
It should be noted that, if the target information does not include the cell information meeting the reporting condition, no cell information is temporarily sent to the network device until the cell information of the neighboring cell corresponding to the frequency band combination supporting the dual-card dual-pass meets the reporting condition, or if the combination of the frequency band of the other cell and the frequency band of the second cell accessed by the first call card is found to be the frequency band combination supporting the dual-card dual-pass, and if the cell information of the cell meets the reporting condition, the step of sending the cell information meeting the reporting condition in the target information to the network device is executed.
Specifically, the measurement result of the cell may include at least one of cell frequency point information, cell network system information, cell ID (Identity document, identity number) information, cell bandwidth information, and the like; the measurement results of the second cell currently accessed by the second subscriber identity module may include an RSRP (Reference Signal Received Power ) measurement and an RSRQ (Reference Signal Received Quality, reference signal received quality) measurement.
The cell frequency point information may be a number of frequencies of cell transmission signals, and the frequencies of the transmission signals correspond to the operating frequency band of the cell, for example, the operating frequency band of the cell may be 2570MHz-2620MHz (Mega Hertz, fluctuation frequency unit: megahertz); the cell network system information can provide network type information of a network for a cell, specifically can be 2G (2 th-Generation Mobile Communication Technology, second generation mobile communication technology), 3G (3 th-Generation Mobile Communication Technology, third generation mobile communication technology), 4G, 5G and other network types, and further can divide the cell into NR cells and LTE cells based on the cell network system information, wherein the NR cells are 5G networks, and the LTE cells are 4G networks; the cell ID information can be the identification information of the cells, different cells correspond to different identification information, and the identification information and the cells are in one-to-one correspondence; the cell bandwidth information may be the bandwidth of the network provided by the cell.
The RSRP measurement is a linear average of the power contributions of the resource elements carrying the cell-specific reference signal within the measurement bandwidth under investigation. Reflecting the distance between the terminal equipment and the base station; the RSRQ measurement is the ratio of nxrsrp to (E-utracrrier RSSI), where N represents the number of RBs (Radio bearing) in the E-UTRA carrier RSSI measurement bandwidth. The numerator and denominator should be obtained on the same resource and the RSRQ measurement used to reflect the extent to which the terminal device received signal is interfered.
In some embodiments of the present application, the frequency band of the neighboring cell may be determined according to the frequency point information of the neighboring cell corresponding to the operating frequency band; specifically, the neighboring cells may be a number of different neighboring cells, and accordingly, the number of different neighboring cells respectively correspond to different frequency bands. For example, in a plurality of different adjacent cells, when the frequency point of a certain adjacent cell is 18, the frequency band corresponding to the adjacent cell is 815MHz-830MHz; when the frequency point of the adjacent cell is 33, the frequency band corresponding to the adjacent cell is 1900MHz-1920MHz.
Step 320: and receiving the cell indication information sent by the network equipment.
Wherein the cell indication information is determined by the network device based on the received cell information; the cell indication information comprises one of first target cells which are determined by the network equipment based on the received cell information and can be accessed by the second communication card currently and cell switching information related to the first target cells.
Specifically, after transmitting the cell information meeting the reporting condition in the target information to the network device in step 310, the network device determines a first target cell from the cell information with the number greater than 1, and transmits the cell indication information about the first target cell to the terminal device in the form of the cell indication information. In step 320, the terminal device may receive the cell indication information sent by the network device, and switch the cell accessed by the second communication card to the first target cell indicated by the cell indication information through sub-step 231.
In some embodiments of the present application, the cell indication information sent by the network device may be received by a second session card installed in the terminal device, and then the operation corresponding to step 120 or step 230 is performed based on the cell indication information.
Optionally, step 230 may include a substep 231:
Substep 231: and switching the cell accessed by the second communication card into a first target cell indicated by the cell indication information.
In some embodiments of the present application, after receiving the cell indication information sent by the network device through step 320, the terminal device may determine a first target cell indicated in the cell indication information according to the cell indication information, and then switch the cell accessed by the second communication card to the first target cell indicated by the cell indication information. At this time, the frequency band combination formed by the frequency band of the cell accessed by the second call card and the frequency band of the second cell accessed by the first call card is the frequency band combination supporting double-card double-pass, and the first call card and the second call card of the terminal equipment can realize double-card double-pass.
In addition, after switching the cell accessed by the second call card to the first target cell indicated by the cell indication information, the second call card of the terminal device replies an RRC message to the network device, where the RRC reconfiguration message is used to indicate that the switching operation of the current access cell is completed.
In some embodiments of the present application, the frequency band combination corresponding to the first priority may specifically include a 5G frequency band combination supporting dual-card dual-pass and a 4G frequency band combination supporting dual-card dual-pass. And under the condition that the number of the first target cells is larger than 1, transmitting cell information meeting reporting conditions in target information to the network equipment, and switching a cell accessed by the second communication card into the first target cell indicated by the cell indication information after receiving the cell indication information transmitted by the network equipment. And under the condition that the frequency band combination of the first target cell comprises the 5G frequency band combination supporting double-card double-pass, the target information is the first cell information of the adjacent cell supporting the 5G frequency band combination supporting double-card double-pass, and under the condition that the frequency band combination of the first target cell does not comprise the 5G frequency band combination supporting double-card double-pass or the first cell information does not comprise the cell information meeting the reporting condition, the target information is the second cell information of the adjacent cell supporting the 4G frequency band combination supporting double-card double-pass. Therefore, when the frequency band combination of the first target cell comprises the 5G frequency band combination supporting double-card double-pass, the cell information of the first target cell corresponding to the 5G frequency band combination supporting double-card double-pass is preferentially sent to the network equipment, so that the cell accessed by the second calling card is preferentially switched into the first target cell corresponding to the 5G frequency band combination supporting double-card double-pass, the residence probability of the second calling card in the 5G frequency band is improved while the first calling card and the second calling card are ensured to support double-card double-pass, and the communication quality of the second calling card is further ensured. In addition, when the frequency band combination of the first target cell includes a 5G frequency band combination supporting dual-card dual-pass, and the cell information of the first target cell meets the reporting condition, measurement of adjacent cells supporting the 4G frequency band combination supporting dual-card dual-pass in the first target cell is not needed, so that unnecessary power consumption of the terminal device is reduced.
Step 230: and switching the cell accessed by the second communication card into the first target cell.
In this embodiment, step 230 is the same as step 120 described above, and will not be described here again.
Optionally, in the case that the target information does not include the cell information meeting the reporting condition, the cell switching method may further include steps 410 to 430:
step 410: and under the condition that the target information does not comprise the cell information meeting the reporting condition, selecting a frequency band from the alternative frequency bands as a target frequency band, and tuning the frequency of the second communication card to the target frequency band.
In step 410, when the target information in step 310 does not include the cell information meeting the reporting condition, a frequency band may be selected from the candidate frequency bands as the target frequency band, the frequency of the second communication card is tuned to the target frequency band, and a search for a neighboring cell not in the neighboring cell list is performed, so as to provide an execution basis for steps 420 and 430.
The frequency band combination formed by the alternative frequency band and the frequency band of the second cell supports double-card double-pass. The alternative frequency band may include a frequency band combination supported by an operator to which the second communication card belongs and composed of a frequency band of the second cell supports a dual-card dual-pass 5G frequency band and a 4G frequency band.
It should be noted that, in the terminal device, when the first calling card is in a calling state and the second calling card is in a non-calling state, and the target information does not include the cell information meeting the reporting condition, the second calling card disconnects the RRC connection, and then step 410 is executed.
In some embodiments of the present application, if the target information does not include the cell information meeting the reporting condition, the cell information about any first target cell is not sent to the network device, that is, the operation of sending the cell information meeting the reporting condition in the target information to the network device is not performed; and then selecting a frequency band from the alternative frequency bands as a target frequency band, and tuning the frequency of the second communication card to the target frequency band.
The present invention provides a method for implementing normal communication function of a second call card, wherein when a first call card is in a call state and a second call card is in a non-call state, the method ensures the quality of the first call card and the implementation of normal communication function of the second call card, so that when a first cell accessed by the second call card meets a preset cell switching condition, it is ensured that after the second call card performs cell switching, a frequency band combination composed of a frequency band of the second cell accessed by the first call card and a frequency band of the first cell accessed by the second call card supports dual-card dual-pass. Under the condition that the target information does not include the cell information meeting the reporting condition, the condition that the frequency band combination formed by the frequency band combination of the adjacent cells of the second calling card and the frequency band of the second cell accessed by the first calling card supports double-card double-pass is not met, and under the condition, the cell switching operation of the second calling card can be temporarily not executed, so that the switching times of the non-calling card can be reduced, and after the calling card finishes the call, the terminal can also ensure that related services are carried out on the high-priority RAT (Radio Access Technology, wireless access technology).
In some embodiments of the present application, all the frequency bands in the alternative frequency bands may be ordered according to the order of the 5G frequency band preceding the 4G frequency band following the first frequency band, when one frequency band is selected from the alternative frequency bands for the first time as the target frequency band, the first frequency band in the alternative frequency bands may be used as the target frequency band, when one frequency band is selected from the alternative frequency bands for the second time as the target frequency band, the second frequency band in sequence in the alternative frequency bands may be used as the target frequency band, and so on, so as to improve the probability of switching the cell to which the second communication card is connected into the cell corresponding to the 5G frequency band.
After tuning the frequency of the second communication card to the target frequency band, performing cell search in the target frequency band, and executing step 420 if there is a second target cell whose signal strength meets the target strength condition in the searched cells; in case there is no second target cell of the searched cells for which the signal strength meets the target strength condition or no cell is searched, step 430 is performed.
After the frequency of the second communication card is tuned to the target frequency band, when the cell search is performed in the target frequency band, the cell to be searched is other adjacent cells not in the adjacent cell list, and the adjacent cell list is a measurement adjacent cell list provided by the RRC reconfiguration message issued by the network equipment, so that the opportunity of missing the cell switching of the second communication card due to the fact that the measurement adjacent cell list does not include adjacent cells which support double-card double-pass with the frequency band combination formed by the frequency band of the second cell can be prevented.
Step 420: and under the condition that a second target cell with signal strength meeting the target strength condition exists in the cell corresponding to the target frequency band, switching the cell accessed by the second communication card into the second target cell.
The target strength condition corresponding to the signal strength may specifically be a minimum value that the signal strength can meet the signal strength of the communication service normally performed by the second communication card.
Specifically, in step 410, the frequency of the second calling card is tuned to a target frequency band, a search is performed for a neighboring cell not in the neighboring cell list, and in the case that a second target cell with signal strength meeting the target strength condition exists in the cells searched for in the target frequency band, the cell to which the second calling card is connected may be switched to the second target cell through step 420.
In some embodiments of the present application, the cells corresponding to the target frequency band may be further ranked according to the signal strength, and the cell with the highest signal strength may be determined as the second target cell.
Specifically, when there is a second target cell whose signal strength meets the target strength condition in the cell corresponding to the target frequency band, the second target cell may be measured, cell information may be obtained, the cell information may be used as target information, and after the operations corresponding to the steps 310 and 320 are executed, the cell to which the second calling card is connected is switched to the second target cell.
Step 430: and under the condition that a cell with the signal strength meeting the target strength condition does not exist in the cell corresponding to the target frequency band, updating the target frequency band to a frequency band which is not selected as the target frequency band in the alternative frequency bands, and tuning the frequency of the second communication card to the target frequency band.
Specifically, in step 410, the frequency of the second calling card is tuned to the target frequency band, searching for the adjacent cells not in the adjacent cell list is performed, and in the case that there is a second target cell with the signal strength meeting the target strength condition in the cells not searched for in the target frequency band, the target frequency band may be updated to the frequency band not selected as the target frequency band in the alternative frequency bands through step 430, and the frequency of the second calling card is tuned to the target frequency band, so as to continue the cell searching.
In some embodiments of the present application, in a case where there is no cell whose signal strength meets the target strength condition in the cell corresponding to the target frequency band, the target frequency band may be updated to a frequency band that is not selected as the target frequency band from the candidate frequency bands. In an exemplary embodiment, when a first frequency band of the candidate frequency bands is used as the target frequency band, in a case where a cell whose signal strength meets the target strength condition does not exist in a cell corresponding to the target frequency band, the target frequency band may be updated to a second frequency band, which is not selected as the target frequency band, among the candidate frequency bands, then the frequency of the second communication card is tuned to the second frequency band, which is used as the target frequency band, and then the cell search is performed, in a case where a cell whose signal strength does not meet the target strength condition does not exist in a cell corresponding to the second frequency band, the target frequency band may be continuously updated to a third frequency band, which is not selected as the target frequency band, among the candidate frequency bands, other than the first frequency band and the second frequency band, then the frequency of the second communication card is tuned to the third frequency band, which is used as the target frequency band, and then the cell search is performed until, in a case where a second target cell whose signal strength meets the target strength condition exists in the cell corresponding to the target frequency band, the cell is switched to the second target frequency band.
