It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a network selection method for a dual-card dual-standby terminal, which is applicable to a dual-card dual-standby terminal for network registration, and the method may be executed by a terminal device provided in an embodiment of the present application, where a network selection apparatus for a dual-card dual-standby terminal of the terminal device may be implemented in a software and/or hardware manner, as shown in fig. 1, a specific scheme provided in this embodiment is as follows:
step S101, first network registration information of a first identity card and second network registration information of a second identity card are obtained.
For the terminal equipment with double cards and double standby, two SIM cards are installed and respectively defined as a first identity identification card and a second identity identification card. After the network registration of the identity card is completed, registration information, such as a registered cell, a frequency point and the like, is correspondingly recorded. Taking the android system as an example, the network registration information in the identification cards is respectively obtained through TelephonManager objects in the API. The first network registration information is a registration cell and a frequency point after the network registration of the first identity card is successful, and the second network registration information is a registration cell and a frequency point after the network registration of the second identity card is successful.
Step S102, if the first network registration information is different from the second network registration information, determining a current first signal strength of the first identity card and a current second signal strength of the second identity card.
Wherein the stronger the signal strength, the higher the data communication efficiency and stability. In an embodiment, when it is determined that the network registration information of the first identification card and the network registration information of the second identification card are different, the current network signal strength of the first identification card and the current network signal strength of the second identification card are respectively obtained, which may be, for example, as follows:
and step S103, performing network registration on the identification card with low signal strength according to the network registration information corresponding to the identification card with high signal strength.
After the respective signal strengths corresponding to the first identity recognition card and the second identity recognition card are determined, network registration is carried out on the identity recognition card with low signal strength according to the network registration information corresponding to the identity recognition card with high signal strength. For example, if the signal strength of the first identification card is greater than the signal strength of the second identification card, the second identification card is registered to the cell and/or frequency point where the first identification card is registered, and if the signal strength of the second identification card is greater than the signal strength of the first identification card, the first identification card is registered to the cell and/or frequency point where the second identification card is registered.
According to the above content, after two identification cards in the dual-card dual-standby terminal register to the network respectively, the identification card with the poorer signal strength is registered to the cell of the identification card with the stronger signal strength through the determination of the respective signal strength, so that the network selection process of the dual-card terminal is optimized, the bottom layer radio frequency resource calling is facilitated, and the resource waste is reduced.
It should be noted that, when the first identity card and the second identity card are provided by the same operator or the terminal device is in a roaming state, the first identity card and the second identity card may share the same registration cell and frequency point.
Fig. 2 is a flowchart of another method for selecting a network of a dual-card dual-standby terminal according to an embodiment of the present application, and optionally, after determining a current first signal strength of the first identity card and a current second signal strength of the second identity card, the method further includes: determining an absolute value of a difference in intensity values of the first and second signal strengths; correspondingly, the network registration of the identity card with low signal strength according to the network registration information corresponding to the identity card with high signal strength comprises: and if the absolute value of the difference between the strength values of the first signal strength and the second signal strength is greater than a preset value, performing network registration on the identification card with low signal strength according to the network registration information corresponding to the identification card with high signal strength. As shown in fig. 2, the technical solution is as follows:
step S201, obtain first network registration information of the first identity card and second network registration information of the second identity card.
Step S202, if the first network registration information is different from the second network registration information, determining a current first signal strength of the first identity card and a current second signal strength of the second identity card.

Wherein the preset value can be 5db, 8db or 10db, etc.
In one embodiment, when the absolute value of the difference between the first signal strength and the second signal strength reaches a preset value, the registration cell of the identification card with low signal strength is registered as the registration cell corresponding to the identification card with high signal strength.
Therefore, when the difference between the signal strengths of the first identity card and the second identity card in the dual cards is detected to be large, the cell reselection of the identity card with the poor signal is executed, and the cell registered by the identity card with the high signal strength is reselected, so that the network selection process of the dual-card dual-standby terminal is optimized, the bottom layer radio frequency resource calling is facilitated, the resource waste is reduced, and the resource consumption caused by frequent cell switching is avoided.
Fig. 3 is a flowchart of another method for selecting a network of a dual-card dual-standby terminal according to an embodiment of the present application, and optionally, after registering a registration cell of an identity card with low signal strength as a registration cell corresponding to an identity card with high signal strength, the method further includes: and if the registered cell change event of the first identity identification card or the second identity identification card is detected, simultaneously changing the registered cells of the first identity identification card and the second identity identification card. As shown in fig. 3, the technical solution is as follows:
step S301, first network registration information of the first identity card and second network registration information of the second identity card are obtained.
Step S302, if the first network registration information is different from the second network registration information, determining a current first signal strength of the first identification card and a current second signal strength of the second identification card.

Step S304, if the absolute value of the difference between the strength values of the first signal strength and the second signal strength is greater than a preset value, registering the registration cell of the identification card with low signal strength as the registration cell corresponding to the identification card with high signal strength.
Step S305, if the registered cell change event of the first identity identification card or the second identity identification card is detected, the registered cells of the first identity identification card and the second identity identification card are changed at the same time.
In the network selection process of the terminal equipment, adjacent cells and corresponding frequency points are scanned, and if the scanned signal strength is superior to that of a currently connected registered cell, a registered cell change event is triggered to be connected to a cell with better signal strength. In one embodiment, when detecting that one identification card changes the registration cell, the registration cell of the other identification card is changed at the same time, so that the simultaneous change of the registration cells of the two identification cards of the dual-card terminal equipment is realized.
Therefore, for the dual-card dual-standby terminal, the registration cell of each identity identification card is changed simultaneously, the problem of high resource consumption caused by independently scanning the registration cell is avoided, and the network selection process is optimized.

Wherein the preset value may be-80 dBm. If the signal strength of one of the identification cards is detected to be low, step S403 is executed.
Step S403, determining whether the operators of the first identification card and the second identification card are the same, if yes, executing step S404, and if no, executing step S410.
Illustratively, the operator corresponding to the identity card may be determined by reading the recorded PLMN (Public Land Mobile Network) code of the identity card. The PLMN is a Network established and operated by an operator approved by a government or a government to provide a land Mobile communication service to the public, wherein the PLMN includes a Mobile Network Code (MNC), such as 00 used by a china Mobile TD system, 01 used by a china unicom GSM system, 02 used by a china Mobile GSM system, 03 used by a china telecommunication CDMA system, determines whether operators of the first identity card and the second identity card are the same according to the number of the MNC Code, and if the MNC codes are the same, the operators of the first identity card and the second identity card are the same, otherwise, the operators of the first identity card and the second identity card are different, and the PLMN can be determined by reading other types of word Code information (such as HPLMN, EHPLMN, and the like). In one embodiment, when the operators of the first identification card and the second identification card are the same, step S404 is performed, and if the operators of the first identification card and the second identification card are the same, step S410 is performed.

And step S407, judging whether the absolute value is larger than a preset value, if so, executing step S408, otherwise, executing step S406.
Step S408, registering the registration cell of the identification card with low signal strength as the registration cell corresponding to the identification card with high signal strength.
Step S409, if the registered cell change event of the first identity identification card or the second identity identification card is detected, the registered cells of the first identity identification card and the second identity identification card are changed at the same time.
And step S410, when the cell information meeting the registration condition is detected, reselecting the registered cell for the first identity identification card and the second identity identification card at the same time.
Specifically, the cell registration procedure may be:
scanning the average intensity of the radio frequency signal and the measurement signal, and locking the frequency point with the highest signal intensity;
searching a Frequency Correction Channel (FCCH) Channel, if the highest Frequency point to be locked is a Broadcast Control Channel (BCCH) Frequency point, synchronizing with the BCCH Frequency point by decoding a Synchronization Channel (SCH), reading system information on the BCCH Frequency point, judging whether the cell can complete registration according to the read system information, if so, performing network registration, residing in the cell, and if not, continuing to scan and monitor all other frequencies to select to reside.
