Technical Field
The present application relates to the field of communications technologies, and in particular, to a network searching method, a terminal, a device, and a storage medium for a private network card.
Background
When the terminal searches for a network, if the communication card in the terminal is a private network card, the terminal registers the private network card in the private network, so that the private network card can access the private network.
When the terminal does not search for the private network and only searches for other networks, the terminal may attempt to register for the private network card in the other networks, such as a public network. In this case, the private network card is rejected for other network registrations, which may cause the private network card to be set in an invalid state or the terminal to stop performing network registration for the private network card within a certain time, which may cause the terminal not to perform network registration for the private network card within a certain time. This means that, during this period of time, when the terminal moves to a place covered by the private network, the terminal cannot timely register for the private network card, so that the private network card cannot timely access the private network.
Therefore, how to improve the network searching method aiming at the special network card makes the special network card more easily access to the special network has very important significance.

Therefore, the private network card is set to be in the preset state under the condition that the private network matched with the private network card is not searched and other networks are determined to exist, and the registration operation of the private network card on the other networks is not executed, so that the private network card cannot be rejected due to registration on the other networks, and further, the private network card cannot be registered on the private network within a certain time due to registration rejection. When the terminal moves to a place covered by the private network, the terminal can timely register the private network card, so that the private network card can access the private network.

Detailed Description
The following describes in detail the embodiments of the present application with reference to the drawings attached hereto.
In the following description, for purposes of explanation rather than limitation, specific details are set forth such as the particular system architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present application.
The term "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship. Further, the term "plurality" herein means two or more than two. Additionally, the term "at least one" herein means any one of a variety or any combination of at least two of a variety, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a network searching method for a specific network card according to an embodiment of the present application. Specifically, the method may include the steps of:
step S11: and after detecting that the communication card is the special network card, the terminal searches the network.
The private network card refers to a communication card for a private network, which is a private network serving a specific department or group. The communication card is, for example, a Subscriber Identity Module (SIM) card or a Universal Subscriber Identity Module (USIM) card.
When the terminal detects that the existing communication card is the special network card, the terminal identifies the communication card in the terminal, and confirms that the communication card in the terminal is the special network card. The terminal searches the network, namely the terminal identifies the network in the outgoing radio frequency signal according to the received radio frequency signal. It is understood that, when the terminal performs the network search, a private network matching the private network card may be searched, and other networks may also be searched, for example, a private network not matching the private network card, or a public network.
In a specific implementation scenario, the network type of the private network matched with the private network card is a Long Term Evolution (LTE) network. In another specific implementation scenario, the network of the private network matched with the private network card at least includes one of the following networks: registered Public Land Mobile Network (RPLMN), equivalent Public Land Mobile Network (EPLMN), equivalent Home Public Land Mobile Network (EHPLMN), and Home Public Land Mobile Network (HPLMN), user Controlled Public Land Mobile Network (UPLMN), operator Controlled Public Land Mobile Network (OPLMN).
Step S12: judging whether a private network matched with the private network card is searched, and determining whether other networks exist.
When the terminal searches for a network, it can determine which networks are included in the radio frequency signal received by the terminal through full-band scanning, and in the determined existing networks, the terminal can obtain a public land mobile network list (plmn list) matched with the private network card and other networks (other private networks or public networks). Thus, the terminal can determine whether other networks exist during network searching. In addition, the terminal will try to initiate registration to the network in the plmn list for the private network card, and if the registration is successful, it can be determined that the terminal searches for the private network matching the private network card. If the registration is unsuccessful, the terminal can be determined not to search the private network matched with the private network card. Step S13: if the private network matched with the private network card is not searched and other networks are determined to exist, the private network card is set to be in a preset state, and the registration operation of the private network card on other networks is not executed.
When the terminal determines that other networks exist but no terminal searches a private network matched with the private network card, the terminal sets the private network card to be in a preset state and does not execute the registration operation of the private network card on the other networks. At this time, the terminal does not perform the operation of registering the network for the private network card.
Therefore, the private network card is set to be in the preset state under the condition that the private network matched with the private network card is not searched and other networks exist, and the registration operation of the private network card on other networks is not executed, so that the private network card cannot be rejected because of registration on other networks, and further, the private network card cannot be registered on the private network within a certain time because of registration rejection. When the terminal moves to a place covered by the private network, the terminal can timely register the private network card, so that the private network card can access the private network.
When the terminal searches for the private network matched with the private network card, the terminal can perform registration operation for the private network card to the private network matched with the private network card. When the terminal does not search any network, the terminal can set the private network card to be in a preset state.
In one implementation scenario, the default state is a no service state. The step S13 of setting the private network card to the preset state may specifically include: and setting the special network card to be in a non-service state, and stopping the network searching operation of the special network card.
In a no-service state, the private network card cannot communicate with the base station, that is, the private network card cannot access the network. In step S13, because the dedicated network matching the dedicated network card is not searched, the terminal may set the dedicated network card to a no-service state, and the terminal may also stop the network searching operation of the dedicated network card, that is, the terminal may not perform the network searching operation for the dedicated network card.
Therefore, by stopping the network searching operation of the special network card, the terminal does not receive the paging message (paging) and updates the system message, and the terminal can also reduce the power consumption caused by cell selection in the network searching process, so that the overall power consumption of the terminal is reduced, and the cruising level of the terminal is improved.
In one implementation scenario, the default state includes a call restricted state or a no service state. The special network card is set to be in a call limiting state, namely the special network card can only initiate an emergency call. And setting the special network card to be in a non-service state, namely the special network card cannot communicate with the base station. The step S13 of setting the private network card to the preset state specifically includes the following steps:
step S131: and judging whether other communication cards except the special network card in the terminal can initiate emergency calls under the current network condition.
The other communication cards in the terminal except the special network card can comprise other special network cards or public network cards. After the terminal does not search the private network matched with the private network card, the terminal can determine the state of the private network card by judging whether other communication cards except the private network card can initiate an emergency call under the current network condition. Whether the emergency call can be initiated by the current network condition of the other communication card can be understood as whether the emergency call can be initiated by the other communication card at the current time under the conditions of not switching cells, not switching network types (for example, switching a 3G network from a 4G network), not switching network frequency bands and the like.
When other communication cards can initiate an emergency call under the current network condition, the emergency call does not need to be initiated by using a special network card; when other communication cards cannot initiate an emergency call under the current network condition, a dedicated network card may be needed to initiate the emergency call.
In a specific implementation scenario, the determining whether the other communication cards except the specific network card in the terminal can initiate the emergency call may specifically include the following steps S1311 to S1313.
Step S1311: it is determined whether other communication cards are currently camped on a cell and whether the camped cell supports an emergency call.
The communication card needs to stay in a cell to initiate an emergency call. Thus, it may be determined whether other communication cards support emergency calls in the current network conditions by determining whether the other communication cards are already camped in a cell and whether the camped cell supports emergency calls.
Step S1312: and if the other communication cards are already resident in the cell and the resident cell supports the emergency call, confirming that the other communication cards can initiate the emergency call under the current network condition.
When the terminal detects that other communication cards are already resident in the cell and the resident cell supports the emergency call, the terminal can confirm that the other communication cards can initiate the emergency call under the current network condition.
Step S1313: and if the other communication cards do not reside in the cell or the resident cell does not support the emergency call, confirming that the other communication cards can not initiate the emergency call under the current network condition.
When the terminal detects that other communication cards do not reside in the cell, meaning that the other communication cards cannot communicate with the base station, it may be determined that an emergency call cannot be initiated under the current network conditions.
When other communication cards are already camped on a cell, but the camped-on cell does not support an emergency call, meaning that the other communication cards need to be handed over to the cell before an emergency call may be initiated. Then it is also confirmed that other communication cards cannot initiate an emergency call under the current network conditions.
Step S132: if yes, the special network card is set to be in a non-service state, and the network searching operation of the special network card is stopped.
If the terminal detects that other communication cards can initiate the emergency call, the emergency call is not initiated by the special network card, the special network card can be set to be in a no-service state at the moment, and the network searching operation of the special network card is stopped, so that the overall power consumption of the terminal is reduced.
Step S133: if not, the special network card is set to be in a call limiting state, and limited service network searching is initiated for the special network card.
If the terminal detects that the other communication card is not capable of initiating an emergency call, it means that a dedicated network card may need to be used to initiate the emergency call. Therefore, the terminal can set the special network card to be in a call-restricted state, and initiate a network search for restricted services for the special network card, so that the special network card can reside in a cell and initiate an emergency call.
Therefore, whether the terminal needs to initiate limited service network searching for the special network card or not can be determined by judging whether other communication cards can initiate emergency calls under the current network condition. When it is determined that other communication cards can initiate an emergency call under the current network condition, the special network card is set to be in a non-service state, and the network searching operation of the special network card is stopped, so that the overall power consumption of the terminal can be reduced.
In one embodiment, if the terminal searches for a private network matching the private network card, the terminal may perform registration of the private network card in the matching private network. If the terminal does not search the private network matched with the private network card and determines that other networks do not exist, the terminal can directly set the private network card to be in a no-service state.
Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of the network searching method for the specific network card of the present application. Specifically, the method may include the steps of:
step S21: and after detecting that the existing communication card is the special network card, the terminal searches the network.
For a detailed description of this step, please refer to step S11 above, which is not described herein again.
Step S22: judging whether a private network matched with the private network card is searched, and determining whether other networks exist.
For a detailed description of this step, please refer to step S12 above, which is not described herein again.
Step S23: and if the private network matched with the private network card is not searched and other networks are determined to exist, setting the private network card to be in a preset state, and not executing the registration operation of the private network card on the other networks.
For a detailed description of this step, please refer to step S13 above, which is not described herein again.
After the private network card is set to the preset state, the embodiment may further include the following steps S24 to S26.
Step S24: and judging whether the duration of the private network card in the preset state is greater than the preset duration.
After the private network card is set to be in the preset state, the private network card may be in a no-service state or a limited-service state, and at this time, the private network card is in a state of not normally accessing the network. Therefore, whether the special network card needs to be adjusted or not can be determined by judging whether the duration of the special network card in the preset state is greater than the preset duration or not. The preset time period is, for example, 20 seconds, 2 minutes, etc., and the setting of the preset time period is not limited and can be adjusted as needed.
When the duration of the private network card in the preset state is longer than the preset duration, executing the step S25; and when the duration of the private network card in the preset state is less than the preset duration, executing the step S26.
Step S25: and executing normal network searching operation.
The terminal executes normal network searching operation, which means that the terminal initiates normal network searching operation for the private network card, so that the private network card can normally access the private network. In a specific implementation scenario, a timer may be set to calculate the duration of the private network card in a preset state. When the timer is overtime, it means that the duration of the private network card in the preset state is longer than the preset duration, and then step S25 can be executed.
Step S26: and maintaining the preset state of the special network card.
The duration that the private network card is in the preset state is less than the preset duration, and the terminal can continue to maintain the preset state of the private network card. At this time, the terminal may re-execute step S24, and when the duration that the private network card is in the preset state is longer than the preset duration, the terminal performs the normal network searching operation again.
Therefore, by judging whether the duration of the private network card in the preset state is greater than the preset duration, the terminal can execute normal network searching operation when the duration of the private network card in the preset state is greater than the preset duration, so that the private network card can normally access the private network, and the communication capacity of the private network card is guaranteed.
