detailed description

The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

The term "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two. In addition, the term "at least one" herein means any one of a variety or any combination of at least two of the more, for example, including at least one of A, B, and C, which may mean including from A, Any one or more elements selected from the set formed by B and C.

Please refer to FIG. 1 . FIG. 1 is a schematic flow chart of an embodiment of a network search method for a private network card of the present application. Specifically, the following steps may be included:

Step S11: after the terminal detects that the existing communication card is a dedicated network card, it performs a network search.

The private network card refers to the communication card used for the private network, and the private network is a professional network serving a specific department or group. The communication card is, for example, a subscriber identity card, namely a SIM (Subscriber Identity Module) card, or a global subscriber identity card, namely a USIM (Universal Subscriber Identity Module) card.

The terminal detects that the existing communication card is a private network card, that is, the terminal confirms that the communication card in the terminal is a private network card by identifying the internal communication card. The terminal performs a network search, that is, the terminal identifies what kind of network exists in the radio frequency signal according to the received radio frequency signal. It is understandable that when the terminal performs a network search, it may search for a private network that matches the private network card, or it may search for other networks, such as a private network that does not match the private network card, or a public network The internet.

In a specific implementation scenario, the network type of the private network matched with the private network card is a long term evolution (LTE, Long Term Evolution) network. In another specific implementation scenario, the private network network matched with the private network card includes at least one of the following networks: a registered public land mobile network (RPLMN, Registered Public Land Mobile Network), an equivalent public land mobile network (EPLMN, Equivalent Public Land Mobile Network), Equivalent Home Public Land Mobile Network (EHPLMN, Equivalent Home Public Land Mobile Network) and Home Public Land Mobile Network (HPLMN, Home Public Land Mobile Network), User Controlled Public Land Mobile Network (User Controlled PLMN, UPLMN ), the operator controls the public land mobile network (Operator Controlled PLMN, OPLMN).

Step S12: Judging whether a private network matching the private network card is found, and determining whether there are other networks.

When the terminal is performing a network search, it can determine which networks will be included in the radio frequency signal received by the terminal by scanning the entire frequency band. Among the confirmed existing networks, the terminal can obtain a public land mobile network list (plmn list) that matches the private network card and Other networks (other private or public networks). In this way, the terminal can determine whether other networks exist when searching for the network. In addition, the terminal will try to register the private network card with the network in the plmn list. If the registration is successful, it can be determined that the terminal has searched for a private network that matches the private network card. If the registration is unsuccessful, it can be determined that the terminal cannot search for a dedicated network that matches the dedicated network card. Step S13: If no private network matching the private network card is found, and it is determined that there are other networks, set the private network card to a preset state, and do not perform the registration operation of the private network card on other networks.

When the terminal determines that other networks exist, but no terminal searches for a private network that matches the private network card, the terminal will set the private network card to a preset state, and will not perform the registration operation of the private network card on other networks. At this time, the terminal will not perform the operation of registering the network for the private network card.

Therefore, when no private network matching the private network card is found and it is determined that there are other networks, the private network card is set to a preset state, and the registration operation of the private network card in other networks is not performed, so that the private network card does not It will be rejected because of registration on other networks. Furthermore, the private network card will not be unable to register on the private network within a certain period of time because of being rejected for registration. When the terminal moves to a place covered by the private network, the terminal can register for the private network card in time, so that the private network card can access the private network.

When the terminal searches for a private network that matches the private network card, the terminal can initiate a registration operation for the private network card to the private network that matches the private network card. When the terminal does not search for any network, the terminal can set the dedicated network card to a preset state.

In a specific implementation scenario, the preset state is a no-service state. The "setting the private network card to a preset state" in the above step S13 may specifically include: setting the private network card to a no-service state, and stopping the network search operation of the private network card.

In no service state, the dedicated network card cannot communicate with the base station, that is, the dedicated network card cannot access the network. In step S13, because no private network matching the private network card is found, the terminal can set the private network card to the no-service state, and the terminal will also stop the network search operation of the private network card, that is, the terminal will not be a private network card Perform a search operation.

Therefore, by stopping the network search operation of the dedicated network card, the terminal will not receive the paging message (paging) and update the system message, and the terminal can also reduce the power consumption caused by cell selection during the network search process, so that the terminal's The overall power consumption is reduced and the battery life of the terminal is improved.

In a specific implementation scenario, the preset state includes a restricted call state or a no-service state. Set the dedicated network card to the restricted call state, that is, the dedicated network card can only initiate emergency calls. Set the private network card to no service state, that is, the private network card cannot communicate with the base station. The "setting the private network card to the preset state" in the above step S13 specifically includes the following steps:

Step S131: Determine whether other communication cards in the terminal except the private network card can initiate an emergency call under the current network conditions.

The communication cards other than the private network card in the terminal may include other private network cards or public network cards. After the terminal does not search for a private network that matches the private network card, the terminal can decide what state to set the private network card to by judging whether other communication cards other than the private network card can initiate an emergency call under the current network conditions. Whether the current network conditions of other communication cards can initiate an emergency call can be understood as other communication cards at the current moment, without switching cells, without switching network types (such as switching from 4G network to 3G network), without switching network frequency bands, etc. Can make an emergency call.

When other communication cards can initiate emergency calls under the current network conditions, it means that there is no need to use the dedicated network card to initiate emergency calls; when other communication cards cannot initiate emergency calls under the current network conditions, it may be necessary to use the dedicated network card to initiate emergency calls Emergency call.

In a specific implementation scenario, judging whether other communication cards in the terminal except the private network card can initiate an emergency call may specifically include the following steps S1311 to S1313.

Step S1311: Judging whether other communication cards are currently camped in the cell, and whether the camped cell supports emergency calls.

To initiate an emergency call, the communication card needs to stay in the cell. Therefore, it can be determined whether other communication cards support emergency calls under current network conditions by judging whether other communication cards have already camped in the cell and whether the camped cell supports emergency calls.

Step S1312: If other communication cards have camped in the cell, and the camped cell supports emergency calls, confirm that other communication cards can initiate emergency calls under the current network conditions.

When the terminal detects that other communication cards have camped in the cell, and the camped cell supports emergency calls, it can confirm that other communication cards can initiate emergency calls under current network conditions.

Step S1313: If the other communication card does not camp in the cell, or the cell where the cell resides does not support emergency calls, confirm that the other communication cards cannot initiate emergency calls under the current network conditions.

When the terminal detects that other communication cards do not reside in the cell, which means that other communication cards cannot communicate with the base station, it can determine that the emergency call cannot be initiated under current network conditions.

When other communication cards have camped in the cell, but the cell does not support emergency calls, it means that other communication cards need to switch to the cell before they can initiate an emergency call. Then, at this time, it will also be confirmed that other communication cards cannot initiate emergency calls under the current network conditions.

Step S132: If yes, set the private network card to the no-service state, and stop the network search operation of the private network card.

If the terminal detects that other communication cards can initiate an emergency call, it means that there is no need for the dedicated network card to initiate an emergency call. At this time, the dedicated network card can be set to the no-service state, and the network search operation of the dedicated network card can be stopped, so as to reduce the terminal. overall power consumption.

Step S133 : If not, set the dedicated network card to a restricted call state, and initiate a limited service search network for the dedicated network card.

If the terminal detects that other communication cards cannot initiate an emergency call, it means that a dedicated network card may be needed to initiate an emergency call. Therefore, the terminal can set the private network card to the restricted call state, and initiate a restricted service network search for the private network card, so that the private network card can reside in the cell and initiate an emergency call.

Therefore, by judging whether other communication cards can initiate an emergency call under the current network condition, it can be determined whether the terminal needs to initiate a restricted service network search for the dedicated network card. When it is determined that other communication cards can initiate an emergency call under the current network conditions, the overall power consumption of the terminal can be reduced by setting the dedicated network card to the no-service state and stopping the network search operation of the dedicated network card.

In an embodiment, if the terminal searches for a private network matching the private network card, the terminal may perform an operation of registering the private network card with the matching private network. If the terminal does not find a private network that matches the private network card, and it is determined that there is no other network, the terminal can directly set the private network card to a no-service state.

Referring to FIG. 2 , FIG. 2 is a schematic flow chart of another embodiment of the network searching method of the private network card of the present application. Specifically, the following steps may be included:

Step S21: After the terminal detects that the existing communication card is a dedicated network card, it performs a network search.

For a detailed description of this step, please refer to the above step S11, which will not be repeated here.

Step S22: Judging whether a private network matching the private network card is found, and determining whether other networks exist.

For a detailed description of this step, please refer to the above step S12, which will not be repeated here.

Step S23: If no private network matching the private network card is found, and it is determined that there are other networks, set the private network card to a preset state, and do not perform the registration operation of the private network card on other networks.

For a detailed description of this step, please refer to the above step S13, which will not be repeated here.

After the private network card is set to a preset state, this embodiment may further include the following steps S24 to S26.

Step S24: Determine whether the duration of the private network card in the preset state is longer than the preset duration.

After the dedicated network card is set to the default state, the dedicated network card may be in a no-service state or a service-restricted state. At this time, the private network card is not connected to the network normally. Therefore, it may be determined whether the private network card needs to be adjusted by judging whether the time period for which the private network card is in the preset state is longer than the preset time period. The preset duration is, for example, 20 seconds, 2 minutes, etc. The setting of the preset duration is not limited and can be adjusted as required.

When the duration of the private network card in the preset state is longer than the preset duration, step S25 is executed; when the duration of the private network card in the preset state is shorter than the preset duration, step S26 is executed.

Step S25: Execute a normal network search operation.

The terminal performs a normal network search operation, which means that the terminal initiates a normal network search 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 being in the preset state. When the timer expires, it means that the duration of the private network card in the preset state is longer than the preset duration, and step S25 can be executed at this time.

Step S26: Maintain the default state of the private network card.

The time period in which the dedicated network card is in the preset state is shorter than the preset time period, and the terminal can continue to maintain the preset state of the dedicated network card. At this time, the terminal can re-execute step S24, and wait until the time length of the private network card in the preset state is longer than the preset time length, and then the terminal performs a normal network search operation.

Therefore, by judging whether the time length of the private network card in the preset state is greater than the preset time length, the terminal can perform a normal network search operation when the time length of the private network card in the preset state is longer than the preset time length, so that the private network card can normally access the private network to ensure the communication capability of the dedicated network card.

Wherein, the aforementioned terminal 30 further includes a judgment adjustment module.
