For example, the frequency band 890～915MHz of GSM900 can be divided into 125 frequency points. According to the frequency interval of 200KHz, it can be divided into 125 wireless frequency bands of 890MHz, 890.2MHz, 890.4MHz, 890.6MHz, 890.8MHz, 891MHz...915MHz, and each The frequency bands are numbered from 1, 2, 3, 4...125, in fact, only 124 frequency points can be used.

For example, the mobile terminal can first obtain the priority of the supported second operator network of the subscriber identity card as the network of operator A, the network of operator B, and the network of operator C, and then search for the network of operator A according to the priority. For the network of operator A, the priority of the network type supported by the subscriber identity card of the mobile terminal is 4G network, 3G network and 5G network. Therefore, the mobile terminal will first search for the 4G network according to the priority of the network type. network signal. When the mobile terminal searches for the signal of the 4G network, the mobile terminal inquires that the frequency point of the 4G network signal of the A operator network stored locally is 3, so the mobile terminal will search for the 4G network signal of the frequency point 3.

For example, the frequency band 890～915MHz of GSM900 can be divided into 125 frequency points. According to the frequency interval of 200KHz, it can be divided into 125 wireless frequency bands of 890MHz, 890.2MHz, 890.4MHz, 890.6MHz, 890.8MHz, 891MHz...915MHz, and each The frequency bands are numbered from 1, 2, 3, 4...125, in fact, only 124 frequency points can be used.

For example, the obtaining module 401 may first obtain that the priorities of the second carrier network supported by the subscriber identity card are carrier A network, carrier B network and carrier C network, and then the first search module 403 According to the priority, the A operator network is found, and for the A operator network, the priority of the network type supported by the subscriber identity card of the mobile terminal 400 is 4G network, 3G network and 5G network. Therefore, the first search module 403 will first search for the signal of the 4G network according to the priority of the network type. When the first search module 403 searches for a signal of the 4G network, the mobile terminal 400 inquires that the frequency point of the locally stored 4G network signal of the operator A network is 3, so the first search module 403 will search for the frequency point of 3 4G network signal.

The registration module 404 is configured to perform network registration according to the frequency points searched by the first search module 403 , or the second search module 405 , or the third search module 406 .

In the embodiment of the present invention, when the first search module 403 searches for the frequency point stored in the storage module 407 of the second operator network, or when the second search module 405 searches for the frequency point of the first operator network, Or when the third search module 406 searches for a frequency point that is not stored in the storage module 407 of the second operator's network, the registration module 404 may perform network registration according to the searched frequency point.

In the embodiment of the present invention, the specific way for the registration module 404 to perform network registration according to the searched frequency point may be: send a network registration request to the base station according to the transmission frequency specified by the searched frequency point.

For example, the frequency band of the 4G network signal of operator A's network is 1710MHz-1785MHz, therefore, the transmission frequency of frequency point 3 is 1710.4MHz. When the first search module 403 or the second search module 405 or the third search module 406 searches for the 4G network signal of the A operator network with a frequency point of 3, the registration module 404 will send a signal to the base station at the transmission frequency of 1710.4MHz A network registration request, and during the network registration process, the registration module 404 will send a message to the base station at the transmission frequency.

The second search module 405 is configured to search the first operator network according to the network priority set by the mobile terminal 400 when the judging module 402 judges that the first operator network does not match the second operator network stored in the storage module 407. A frequency point of the operator's network.

In the embodiment of the present invention, when the judging module 402 judges that the first operator network does not match the second operator network stored in the storage module 407, the second search module 405 searches the network according to the normal network search process, That is, the frequency point of the first operator network acquired by the acquisition module 401 is searched according to the network priority set by the mobile terminal 400 .

In the embodiment of the present invention, when the second search module 405 searches for a frequency point of the first operator's network, the registration module 404 may perform network registration according to the searched frequency point.

The third search module 406 is configured to search for a frequency point not stored in the storage module 407 of the second operator network when the first search module 403 does not search for a frequency point stored in the mobile terminal 400 by the second operator network point.

In the embodiment of the present invention, when the first search module 403 does not search for the frequency point stored in the storage module 407 by the second operator network, the third search module 406 can search for the second operator network that is not stored in the storage module. Frequency points in module 407. Wherein, the frequency points of the second operator network stored by the storage module 407 may not be all frequency points, and it is also possible that the storage module 407 has not been updated, and the stored frequency point data is relatively old, so the first search module 403 does not search When the frequency points of the second operator network are stored in the storage module 407 , the third search module 406 may search for other frequency points of the second operator network, that is, frequency points not stored in the storage module 407 .

In the embodiment of the present invention, when a frequency point not stored in the storage module 407 of the second operator network is searched, the registration module 404 may perform network registration according to the searched frequency point.

The storage module 407 is configured to store all operator network data in the region where the subscriber identity card configured on the mobile terminal 400 belongs, and operator network data signed with the subscriber operator of the subscriber identity card that has signed a roaming agreement.

In the embodiment of the present invention, the storage module 407 will first store all operator network data in the area where the subscriber identity card configured on the mobile terminal 400 belongs, and operator networks that have signed a roaming agreement with the subscriber operator of the subscriber identity card. data (that is, second operator network data). Wherein, all operator network data in the region to which the subscriber identification card belongs includes all network types of the operator network and frequency points corresponding to each network type, and the second operator network data may include all network types of the operator network, It may also include the network types of the part of the operator's network and the frequency points corresponding to these network types, which are not limited in this embodiment of the present invention.

In the embodiment of the present invention, when the searched network of the first operator has not signed a roaming agreement with the contracted operator of the subscriber identity card configured on the mobile terminal, the mobile terminal can perform network search according to a normal network search process. When the frequency point stored in the mobile terminal by the second operator's network that signed a roaming agreement with the subscriber identity card operator configured on the mobile terminal is not found, the mobile terminal can also search for other frequencies of the second operator's network. Click to register with the network. In this way, the outdated frequency point data stored in the storage module of the mobile terminal can prevent the subscriber identification card from being unable to register with the network, which is beneficial to improving user experience.
