Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The embodiment of the invention provides a mobile data service switching method, which is applied to a terminal, and fig. 1 is a flow chart of the mobile data service switching method in an embodiment of the invention, as shown in fig. 1, the switching method comprises the following steps:
step S101: the current host card resident network is identified.
Here, step S101 may include: the terminal receives a BCCH (Broadcast Control Channel ) channel message issued by the current main card residence network; extracting PLMN (Public Land Mobile Network ) parameters of the current main card resident network according to the BCCH channel message; and identifying the current main card resident network according to the PLMN parameters.
Specifically, after a terminal resides in a cell, receiving a BCCH channel message issued by a network side, and reading PLMN parameters from the BCCH channel message, wherein the PLMN parameters are MCC+MNC, MCC is Mobile Country Code, namely a mobile country code, the MCC resources are uniformly distributed and managed by the International telecommunication Union, the total 3 digits are uniquely identified, and China is 460; the MNC is Mobile Network Code, i.e. mobile network code, and in the same country, if there are multiple PLMNs, it can be distinguished by MNC, i.e. each PLMN is assigned a unique MNC, typically one operator in a certain country corresponds to one or more PLMNs, e.g. there are multiple operators in china, china mobile, china communication and china telecommunication, and there are multiple PLMNs in china mobile, china communication and china telecommunication, respectively, MNC for china mobile uses 00, 02, 04 and 07, MNC for china communication uses 01, 06 and 09, MNC for china telecommunication uses 03, 05 and 11. The terminal identifies the current main card resident network by using the extracted PLMN parameters, for example, the PLMN parameters extracted from the current main card resident network are 46000, 46002, 46004 or 46007, and then identifies the current main card resident network as a china mobile network; extracting the PLMN parameters of the current main card resident network to be 46001, 46006 or 46009, and identifying the current main card resident network as a China Unicom network; and if the PLMN parameter extracted from the current main card resident network is 46003, 46005 or 46011, identifying the current main card resident network as the China telecom network.
Here, before step S101, further includes: reading public land mobile network PLMN parameters in a user identity card; identifying the user identity card according to PLMN parameters in the user identity card; the user identification card comprises a first user identification card and a second user identification card.
In an embodiment, after the terminal is powered on or when a subscriber identity card is inserted into the terminal, the terminal reads an IMSI (International Mobile Subscriber Identification Number, international mobile subscriber identity) in the subscriber identity card, where the IMSI is a flag for distinguishing mobile subscribers, and is a number with a total length not exceeding 15 digits, including PLMN parameters, and according to the read PLMN parameters in the subscriber identity card, the number of subscriber identity cards in the current terminal and the networks respectively supported by the subscriber identity cards can be determined. The PLMN parameter is mcc+mnc, and as described above, the network supported by the subscriber identity module card can be determined by using the PLMN parameter, for example, if the PLMN parameter is 46000, 46002, 46004 or 46007, the subscriber identity module card is identified to support the china mobile network; extracting PLMN parameters of 46001, 46006 or 46009, and identifying that the user identity card supports the China Unicom network; and extracting the PLMN parameters of 46003, 46005 or 46011, and identifying that the user identity card supports the China telecom network.
In particular, the subscriber identity card may be a SIM (Subscriber Identification Module, subscriber identity card), USIM (Universal Subscriber Identity Module, universal subscriber identity card) or UIM (User Identify Module, subscriber identity module), and the subscriber identity card described in embodiments of the present invention is intended to include, but is not limited to, these and any other suitable types of subscriber identity cards.
Specifically, the terminal can support dual-user identification cards or multi-user identification cards, and the DSDS (Dual SIM Dual Standby, dual-card dual-standby) technology of the terminal means that the terminal can insert two user identification cards and can stand by at the same time, and the two user identification cards can comprise a first user identification card and a second user identification card; optionally, the terminal may also insert a plurality of subscriber identity cards and may be standby at the same time, where the plurality of subscriber identity cards may include a first subscriber identity card and a plurality of second subscriber identity cards.
Step S102: it is determined whether the current host card matches the current host card resident network.
Wherein the determining whether the current main card is matched with the current main card residence network comprises: when PLMN parameters of the public land mobile network in the current main card and PLMN parameters of the current main card resident network meet preset conditions, determining that the network supported by the current main card is not matched with the current main card resident network; or when the current main card is not registered to the network or fails to register to the network, determining that the network supported by the current main card is not matched with the resident network of the current main card.
It should be understood that the current main card is a first subscriber identity card currently supporting mobile data service, and when the network supported by the current main card is not matched with the network where the current main card resides, the current main card is switched to a second subscriber identity card matched with the network where the current main card resides, and the first subscriber identity card is updated and set as a current sub-card.
Step S103, under the condition that the current main card is not matched with the resident network of the current main card, the main card or the auxiliary card is switched according to the public land mobile network PLMN parameter in the current main card, the signal intensity of the user identity card or the network state registered by the identity card.
The method comprises the steps that when a public land mobile network PLMN parameter in a current main card and a PLMN parameter of a current main card resident network meet preset conditions, the network supported by the current main card is determined to be not matched with the current main card resident network, and according to the scheme, as the position of a terminal changes in real time, for example, the terminal moves from a first network covered area to a second network covered area, the current main card is still in a state before the terminal moves to the second network covered area, namely, the current main card is still the first user identity card supporting the first network, at the moment, PLMN parameters in the first user identity card and PLMN parameters of the second network are acquired, and the first user identity card and the second network (namely, the current main card resident network) are determined to be not matched.
For the scheme that the network supported by the current main card is not matched with the current main card resident network when the current main card is not registered in the network or fails to register in the network, along with the real-time change of the position of the terminal, such as when the terminal moves from the area covered by the first network to the area covered by the second network, at this time, the current main card is still in a state before the terminal moves to the area covered by the second network because the current main card resident network is changed to the second network, that is, the current main card is still the first user identity card supporting the first network, and at this time, if the first user identity card (that is, the current main card) cannot register in the second network (that is, the current main card resident network) or fails to register in the second network (that is, the current main card resident network), the first user identity card is not matched with the current main card resident network can be determined.
In an alternative embodiment, referring to fig. 2, the steps of determining the current main card and determining that the current main card does not match the current main card residence network by the terminal include:
step S201, judging whether the user identification card supports the current mobile data service. If yes, executing step S202; if the determination result is no, the process proceeds to step S201. Here, the step S201 may be continuously performed in a period of 1 minute, 2 minutes, 5 minutes, or the like, which may be the step S201.
Step S202, determining the user identification card as the current main card. Here, the terminal determines that the subscriber identity card is the current master card, and continues to perform steps S203, S204, and S205, where steps S203, S204, and S205 may be performed simultaneously after step S202.
Step S203, judging whether the PLMN in the current main card and the PLMN parameter of the network where the current main card resides meet preset conditions. If yes, executing step S206; if the determination result is no, the step S203 is continued. Here, the continuing of step S203 may be the periodic execution of step S203, and the period may be 1 minute, 2 minutes, 5 minutes, or the like.
Step S204, judging whether the current main card is not registered in the network. If yes, executing step S206; if the determination result is no, the step S204 is continued. Here, the step S204 may be continuously performed in a period of 1 minute, 2 minutes, 5 minutes, or the like, which is the step S204.
Step S205, judging whether the current main card is registered in the network and fails. If yes, executing step S206; if the determination result is no, the step S205 is continued. Here, the step S205 may be continuously performed in a period of 1 minute, 2 minutes, 5 minutes, or the like, which is performed in step S205.
Step S206, determining that the current main card is not matched with the resident network of the current main card. Here, when any one of the steps S203, S204, and S205 determines yes, it is determined that the current host card does not match the current host card resident network.
In another alternative embodiment, referring to fig. 3, the steps of determining the current main card and determining that the current main card does not match the current main card resident network include:
step S301, judging whether the user identification card supports the current mobile data service. If yes, executing step S302; if the determination result is no, the process proceeds to step S301. Here, the step S301 may be continuously performed in a period of 1 minute, 2 minutes, 5 minutes, or the like.
Step S302, determining the user identification card as the current main card. Here, the terminal determines that the subscriber identity card is the current master card, and proceeds to step S303.
Step S303, judging whether the PLMN in the current main card and the PLMN parameter of the network where the current main card resides meet preset conditions. If yes, executing step S306; if the result is no, the step S304 is continued.
Step S304, judging whether the current main card is not registered in the network. If yes, executing step S306; if the determination result is no, the step S305 is continued.
Step S305, determining whether the current host card fails to register with the network. If yes, executing step S306; if the determination result is no, the step S303 is continued.
Step S306, determining that the current main card is not matched with the resident network of the current main card. Here, when any one of steps S303, S304, and S305 determines yes, it is determined that the current host card does not match the current host card resident network.
Here, when the PLMN parameter corresponding to the public land mobile network in the current main card and the PLMN parameter of the current main card resident network meet a preset condition, determining that the network supported by the current main card is not matched with the current main card resident network includes: and when the first priority PLMN parameter corresponding to the current main card comprises the PLMN parameter of the network where the current main card resides and does not comprise the second priority PLMN parameter of the current main card, determining that the network supported by the current main card is not matched with the network where the current main card resides.
Specifically, the types of PLMN parameters include a plurality of types of PLMN parameters having different priorities, the PLMN parameter type priorities are shown in table 1,
Figure BDA0003664987740000081
Figure BDA0003664987740000091
TABLE 1
In table 1, priority 1 is the highest priority, priority 2 is the next highest priority, and so on, priority 7 is the lowest priority, and the subscriber identity card includes one or more types of PLMNs in table 1, where the HPLMN is the home PLMN and is the same as the PLMN in the IMSI in the subscriber identity card (i.e., mcc+mnc), and there is only one HPLMN for a certain subscriber; RPLMN, EPLMN, UPLMN, OPLMN, VPLMN and other PLMNs, which may be empty, include one PLMN parameter or include multiple PLMN parameters. Because the network has PLMN parameters, when the subscriber identity card has PLMN parameters with multiple priorities, the subscriber identity card will preferentially register to the network with the highest priority of PLMN parameters, for example, when the subscriber identity card has RPLMN, EHPLMN and HPLMN parameters at the same time, and the PLMN parameters of the network include RPLMN, EHPLMN and HPLMN parameters, the subscriber identity card will preferentially register to the network with RPLMN parameters.
In one embodiment, the current host card includes two priority PLMN parameters, e.g., a first priority PLMN parameter, an EHPLMN parameter, and a second priority PLMN parameter, an HPLMN parameter, and wherein the HPLMN parameter is 46000, the EHPLMN parameter includes 46001 but not 46000, the PLMN parameter of the current host card-resident network is 46001, the EHPLMN parameter has a higher priority than the HPLMN parameter, and the EHPLMN parameter includes the PLMN parameter of the current host card-resident network, i.e., the first priority PLMN parameter of the current host card includes the PLMN parameter of the current host card-resident network and does not include the second priority PLMN parameter of the current host card, thereby determining that the network supported by the current host card does not match the current host card-resident network.
Here, when the PLMN parameter corresponding to the public land mobile network in the current main card and the PLMN parameter of the current main card resident network meet a preset condition, determining that the network supported by the current main card is not matched with the current main card resident network further includes: and when the PLMN parameter of the second priority corresponding to the second user identity card is the same as the PLMN parameter of the current main card resident network, determining that the network supported by the second user identity card is matched with the current main card resident network.
Taking an example that the user identification card includes a user identification card X and a user identification card Y, in one embodiment, two user identification cards are set, which are respectively a user identification card X and a user identification card Y, wherein the user identification card X is a main card, the user identification card Y is a sub-card, and PLMN parameter configurations of the user identification card X and the user identification card Y refer to table 2:
user identification card parameter configuration User identification card X User identity identification card Y
HPLMN 44150 44180
EHPLMN 44180 Empty space
TABLE 2
In table 2, the priority of the EHPLMN parameter is higher than the priority of the HPLMN parameter, and the PLMN parameter of the current main card residence network is 44180, because the EHPLMN parameter of the subscriber identity card X includes the PLMN parameter of the current main card residence network and does not include the HPLMN parameter of the subscriber identity card X, it is determined that the network supported by the subscriber identity card X is not matched with the current main card residence network; and determining that the network supported by the user identity card Y is matched with the current main card resident network because the HPLMN parameter of the user identity card Y is the same as the PLMN parameter of the current main card resident network.
Here, in step S103, when it is determined that the current main card is the first subscriber identity card and the current main card does not match the current main card residence network, the current main card is switched to the second subscriber identity card matching the current main card residence network, and the first subscriber identity card is updated and set as the current sub card. Specifically, the method for switching the current main card to a second user identification card matched with the current main card residence network and setting the first user identification card as a current auxiliary card comprises the following steps: and when the number of the second user identification cards matched with the current main card residence network is determined to be a plurality of, switching the current main card to one of the plurality of second user identification cards, and updating and setting the first user identification card as a current auxiliary card. For a terminal which can be simultaneously inserted with a plurality of user identification cards and can be simultaneously standby, when the user identification cards which are matched with the resident network of the current main card are determined to be a plurality of user identification cards when the current main card needs to be switched, one of the user identification cards can be randomly selected to be switched to the current main card, and other user identification cards are taken as auxiliary cards.
Here, the switching the current main card to one of the plurality of second subscriber identity cards includes: acquiring signal strength of a plurality of second user identity identification cards; and switching the current main card to a second user identity identification card with highest signal intensity according to the signal intensity. For a terminal which can be simultaneously inserted with a plurality of user identification cards and can be simultaneously standby, when the user identification cards which are matched with the resident network of the current main card are determined to be a plurality of user identification cards when the current main card needs to be switched, the user identification cards with relatively strongest signal intensity in the plurality of user identification cards can be switched to the current main card, and other user identification cards are used as auxiliary cards.
In summary, in the mobile data service switching method provided in the foregoing embodiment, the terminal identifies a current main card residence network, and when it is determined that a first subscriber identity card currently supporting mobile data service is a current main card and the network supported by the current main card is not matched with the current main card residence network, switches the current main card to a second subscriber identity card matched with the current main card residence network, and updates the first subscriber identity card to be a current sub-card. Therefore, the terminal completes the automatic switching between the main card and the auxiliary card by identifying the current main card resident network and according to the matching condition of the main card and the current main card resident network, so that the current main card supporting the mobile data service can keep matching with the current main card resident network in real time, the capability of supporting the self-adaptive switching of the double-card or multi-card terminal in the network is enhanced, and the use experience of a user is improved.
In order to facilitate further understanding of the mobile data service switching method provided in the embodiments of the present application, a terminal including 3 subscriber identity cards will be described below as an example from the perspective of a first application scenario. In the first application scenario, 3 user identification cards are set, namely a user identification card X, a user identification card Y and a user identification card Z, wherein the user identification card X is a main card, the user identification card Y and the user identification card Z are auxiliary cards, and PLMN parameter configuration of the user identification card X, the user identification card Y and the user identification card Z is shown in table 3:
Figure BDA0003664987740000111
TABLE 3 Table 3
In table 3, the EHPLMN parameters have a higher priority than the HPLMN parameters. The network modes supported by the current main card user identity card X comprise: the network modes supported by the current sub-card user identification card Y and the user identification card Z comprise the following steps of: 4G/3G/2G (or 3G/2G), wherein 5G is an abbreviation for the 5th Generation mobile communication technology, 5th generation mobile communications technology; 4G is an abbreviation for the 4th generation th Generation mobile communication technology, 4th generation mobile communication technology; 3G is an abbreviation for the 3th Generation mobile communication technology, 3 rd generation mobile communications technology; 2G is an abbreviation for the 2th Generation mobile communication technology, 2 nd generation mobile communication technology. Alternatively, the current host card may use the mobile data service according to a network mode set by the user. In table 3, 44380 may be PLMN parameters of network a and 44150 may be PLMN parameters of network B. Referring to fig. 4 in combination, as the location area of the terminal changes, the signal strength of the network a gradually increases and the signal strength of the network B gradually decreases when the terminal enters the network a; and when the terminal enters the network B, the signal strength of the network B is gradually increased, and the signal strength of the network A is gradually weakened.
In the first application scenario, a user identification card X in the terminal is registered on a network B, a user identification card Y and a user identification card Z are registered on a network A, the user identification card Z is a current main card, the user identification card X and the user identification card Y are current auxiliary cards, and the terminal is in the process of moving from the network A to the network B. Referring to fig. 5, the method for the terminal to perform mobile data service handover includes the following steps:
step S501, identifying the current host card residence network. Here, the terminal detects the network states registered by the user identification card X, the user identification card Y, and the user identification card Z in real time or periodically.
Step S502: it is determined whether the subscriber identity card Z is registered with the network B. Here, it is determined whether the EHPLMN parameter in the subscriber identity card Z includes the PLMN parameter of the network B and does not include the HPLMN parameter of the subscriber identity card Z, if yes, step S503 is executed; if the determination result is no, step S501 is executed.
Step S503: and setting the user identification card Z as the current auxiliary card. Here, since the HPLMN parameter of the subscriber identity card Y is the same as the PLMN parameter of the current main card residence network, it is determined that the network supported by the subscriber identity card Y matches the current main card residence network, so that the subscriber identity card Y is set as the current main card, and the subscriber identity card Z is set as the current sub card.
Therefore, the terminal completes automatic switching between the main card and the auxiliary card by identifying the current main card residence network and according to the matching condition of the main card and the current main card residence network, enhances the capability of supporting the self-adaptive switching of the double-card or multi-card terminal in the network, and improves the use experience of users.
In order to facilitate further understanding of the mobile data service switching method provided in the embodiments of the present application, the above terminal including 3 subscriber identity cards is still described from the perspective of the second application scenario by taking the example. In the second application scenario, a user identification card X in the terminal is registered on a network B, a user identification card Y and a user identification card Z are registered on a network A, the user identification card X is a current main card, the user identification card Y and the user identification card Z are current auxiliary cards, and the terminal is in the process of moving from the network B to the network A. Referring to fig. 6, the method for the terminal to perform mobile data service handover includes the following steps:
step S601: the current host card resident network is identified. Here, the terminal detects the network states registered by the user identification card X, the user identification card Y, and the user identification card Z in real time or periodically.
Step S602: it is determined whether the subscriber identity card X is registered with the network a. Here, it is determined whether the EHPLMN parameter in the subscriber identity card X includes the PLMN parameter of the network a and does not include the HPLMN parameter of the subscriber identity card X, if yes, step S603 is executed; if the judgment result is no, the process returns to the execution of step S601.
Step S603: and judging whether at least one of the user identity card Y and the user identity card Z has EHPLMN parameters. Here, whether the user id card Y and the user id card Z have EHPLMN parameters is determined, and if any one of them has EHPLMN parameters, the determination is yes, and step S604 is executed; if neither the subscriber identity card Y nor the subscriber identity card Z has EHPLMN parameters, the determination is no, and step S601 is executed. Taking the configuration of 3 user identification card parameters listed in table 3 as an example, if the user identification card Y does not have EHPLMN parameters and the user identification card Z has EHPLMN parameters, the determination result of step S603 is yes, and step S604 is continuously executed.
Step S604: and judging whether the EHPLMN parameters of the user identity card Y or the user identity card Z comprise PLMN parameters of the network B. Here, whether the EHPLMN parameter of the network B is included in the EHPLMN parameter of the user identity card Y or the EHPLMN parameter of the user identity card Z is determined, if yes, step S605 is executed; if the determination result is no, step S601 is executed. Taking the configuration of 3 user identification card parameters listed in table 3 as an example, since the user identification card Y does not have EHPLMN parameters, and the user identification card Z has EHPLMN parameters, in step S604, it is determined whether the EHPLMN parameters of the user identification card Z include PLMN parameters of the network B, if yes, step S605 is executed; if the judgment result is no, the process returns to the execution of step S601.
Step S605: one of the user identification card Y or the user identification card Z is set as the current main card. Here, if the subscriber identity card Y and the subscriber identity card Z both satisfy the judgment conditions of step S603 and step S604, the current main card is set to be the subscriber identity card Y and the subscriber identity card Z, and the current sub card is set to be the subscriber identity card X. Optionally, when the user identification card Y and the user identification card Z are set as the current main card, the signal strength of the user identification card Y and the user identification card Z can be used as the setting condition of the current main card, and if the signal strength of the user identification card Y is higher than the signal strength of the user identification card Z, the user identification card Y is set as the current main card; if the signal intensity of the user identification card Z is higher than that of the user identification card Y, the user identification card Z is set as the current main card. If the user identification card Y meets the judgment conditions of the step S603 and the step S604, setting the user identification card Y as a current main card and setting the user identification card X as a current auxiliary card; if the subscriber identity card Z meets the judgment conditions of step S603 and step S604, the subscriber identity card Z is set as the current main card, and the subscriber identity card X is set as the current sub card. Taking the configuration of 3 user identification card parameters listed in table 3 as an example, since the user identification card Z has EHPLMN parameters, and the EHPLMN parameters include PLMN parameters of the network B, the user identification card Z is set as the current main card, and the user identification card X is set as the current sub card.
Therefore, the terminal completes automatic switching between the main card and the auxiliary card by identifying the current main card residence network and according to the matching condition of the main card and the current main card residence network, enhances the capability of supporting the self-adaptive switching of the double-card or multi-card terminal in the network, and improves the use experience of users.

Here, it is determined whether the EHPLMN or OPLMN parameters in the subscriber identity card Y include PLMN parameters of the network C and do not include HPLMN parameters of the subscriber identity card Y, if yes, step S703 is executed; if the result is negative, the process returns to step S701.
