Background technique

With the development of science and technology, mobile communication is gradually developing into the 4G era. The so-called 4G refers to the fourth generation mobile communication technology.

In the current GSM (Global System for Mobile Communications) network, the call forwarding query is mainly implemented by sending a query command to the network. Each time the mobile terminal such as the mobile phone enters the voice call transfer interface, the CS domain (circuit switched domain) query command is issued. Get the status of various call forwarding from the network side. Although 4G has a great improvement in information transmission speed compared to 2G/3G, every time you enter the call transfer interface, you still need to send a query command to the network. If the network registers 4G, each query needs to fall back to 2G/3G. The voice service is performed, so that the network state is dropped from 4G to 2G/3G and finally to 4G. At the same time, the slow response of the network will result in the query time being too long, and it is always in the query interface. Therefore, when a user needs to set up call forwarding on a mobile terminal, there is a poor overall experience.

detailed description

The core of the invention is to provide a call forwarding state query method, which can solve each inquiry call. When the transfer occurs, the signal jump causes the waiting time to be too long.

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Specific details are set forth in the following description in order to provide a thorough understanding of the invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar promotion without departing from the scope of the present invention. The invention is therefore not limited by the specific embodiments disclosed below.

Please refer to FIG. 1. FIG. 1 is a flowchart of a call forwarding state query method according to an embodiment of the present invention.

A specific embodiment of the present invention provides a call forwarding status query method, which can be used in a mobile terminal having a 4G network, and the method includes:

S11: Enter the call forwarding query interface and query the call forwarding status.

A mobile terminal such as a mobile phone usually has a call forwarding application, and the user can use the application after the user subscribes to the call forwarding service in the mobile network. Typically, the types of call forwarding include: unconditional call forwarding, busy call forwarding, unanswered call forwarding, and no-signal call forwarding. The user can perform various settings of call forwarding according to requirements. The so-called call transfer inquiry interface is a call transfer setting interface, and the user can perform call forwarding status inquiry and the like on this interface.

It should be noted that the type of call forwarding in this document refers to the type of call forwarding in call forwarding, and the type of call forwarding in the following is the same as this.

S12: Determine whether the call forwarding information of the SIM card is stored in the mobile terminal where the SIM card or the SIM card is located.

In this embodiment, the call forwarding information of the SIM card acquired from the network side may be stored locally, that is, stored in the SIM card or the mobile terminal where the SIM card is located. The user may not remember whether the call forwarding information of the SIM card is stored in the SIM card or the mobile terminal during the operation. Therefore, when the user performs the call forwarding query, the user first performs a local query, that is, whether the SIM card or the mobile terminal is queried. Pre-store the call forwarding information of the SIM card.

S13: If call forwarding information of the SIM card is stored in the SIM card or the mobile terminal, read call forwarding information of the SIM card stored in the SIM card or the mobile terminal.

S14: If the SIM card or the mobile terminal does not store the call forwarding information of the SIM card, send a call forwarding query instruction to the network side, and store the query result in the SIM card or the location. In the mobile terminal, and returning the query result to the call forwarding application of the mobile terminal.

When the call forwarding information of the SIM card is not stored in the SIM card or the mobile terminal, the call forwarding information of the SIM card is obtained from the network side, and then stored in the SIM card or the mobile terminal for later calling. When the query is transferred, it can be queried locally without having to query from the network side again. The so-called call forwarding application that returns the query result to the mobile terminal, that is, the user can directly view the query result through the call forwarding application of the mobile terminal without retiring from the current call forwarding application to re-enter the call query interface and re-query.

In this embodiment, when the same SIM card is queried on the same mobile terminal for the call forwarding state, each subsequent call forwarding query interface first performs a local query, that is, queries the SIM card or the mobile terminal for storage. The call forwarding information of the SIM card does not need to be queried if the local query is successful; if the SIM card or the mobile terminal does not store the call forwarding information of the SIM card, for example, the SIM card is not inserted into the mobile terminal for the first time or the SIM card has not been performed yet. After the call forwarding query, when the call forwarding interface is entered for inquiry, the call forwarding information of the current SIM card is queried through the network, and the call forwarding information of the current SIM card is stored locally, then the call forwarding of the SIM card is queried afterwards. In the state, only local query is needed, and no network query is needed again, thereby avoiding the need for the network query every time the user performs a call transfer query, thereby solving the waiting time caused by a signal jump every time the call is transferred. Too long a problem has improved the user's call forwarding query experience.

Please refer to FIG. 2. FIG. 2 is a flowchart of a call forwarding state query method according to another embodiment of the present invention.

Based on the foregoing embodiments, another specific embodiment of the present invention provides a call forwarding state query method.

In another embodiment of the present invention, the step S141 of the call forwarding status query method is: sending a call transfer query instruction to the network side. After step S141, the method further includes:

S142: Determine whether the mobile terminal and the SIM card are registered to the 4G network.

It is determined whether the network status of the user's mobile terminal is in 4G or 2G/3G, and whether the mobile terminal and the SIM card of the user are registered to the 4G network can be determined according to the current communication standard or network speed of the user's mobile terminal.

S143: If the mobile terminal and the SIM card are registered to the 4G network, determine whether the call forwarding query is completed.

When it is determined that the mobile terminal and the SIM card have been registered to the 4G network, it is further determined whether the call forwarding information of the SIM card is acquired from the network side.

S144: If the call forwarding query is completed, storing the query result in the SIM card or the mobile terminal, and returning the query result to the call forwarding application of the mobile terminal.

If the call forwarding inquiry is completed, the call forwarding information of the queried SIM card is stored in the SIM card or the mobile terminal, that is, the call forwarding information of the SIM card is stored locally.

S145: If the call forwarding query is not completed, the 2G/3G network status is delayed.

The types of call forwarding include: unconditional call forwarding, busy call forwarding, non-answering call forwarding, and no-signal call forwarding. It can be seen that each time a mobile terminal such as a mobile phone enters the call forwarding interface, a CS domain query command is sent to obtain various call forwarding states from the network side, and each type of call forwarding corresponds to a call forwarding state, and each type of call is used. The state of the transfer corresponds to a query command. Therefore, in the call forwarding state query in this embodiment, if the call forwarding information of the SIM card is obtained, multiple queries are sent, in order to ensure frequent network signal state during the query. Change, the network signal is delayed reporting, that is, when the 4G network signal is registered, the 2G/3G network signal is not reported to the application during the incomplete completion of the query process, that is, the query period is always in the 2G/3G network. Knowing that the call forwarding query is completed, the network hops from 2G/3G to 4G, thus avoiding the signal hopping when the call forwarding information corresponding to the type of call forwarding is acquired, and the call forwarding information corresponding to the type of another call forwarding is obtained. It also requires a signal transition.

It should be noted that if the current mobile terminal and the SIM card are not registered with the 4G network, it is also possible to directly determine whether the query is completed, but if the query is not completed, the 2G/3G network status does not need to be delayed.

Please refer to FIG. 3. FIG. 3 is a flowchart of a call forwarding state query method according to another embodiment of the present invention.

On the basis of the above-mentioned embodiments, the call forwarding state query method provided by an embodiment of the present invention, when the mobile terminal is powered on, further includes:

S21: Determine whether the SIM card in the mobile terminal is inserted into the mobile terminal for the first time.

The determining whether the SIM card in the mobile terminal is inserted into the mobile terminal for the first time is specifically determining whether the mobile terminal stores an ICCID of a SIM card in the mobile terminal. That is, whenever a SIM card is inserted into the mobile terminal, the mobile terminal records the ICCID of the SIM card as a flag for determining whether the SIM card is inserted into the mobile terminal for the first time.

Performing the above implementation if the SIM card in the mobile terminal is inserted into the mobile terminal for the first time Step S141 in the manner: issuing a call forwarding query instruction to the network side, and subsequent steps.

If the SIM card in the mobile terminal is not inserted into the mobile terminal for the first time, step S12 is performed: determining whether call forwarding information of the SIM card is stored in the SIM card or the mobile terminal, and a subsequent step.

It should be noted that the ICCID of the SIM card is the integrated circuit card identification code in the SIM card, which is the unique identification number in the current SIM card.

It should be noted that the present embodiment only preferably determines whether the mobile terminal stores the ICCID of the SIM card in the mobile terminal, and determines whether the SIM card in the mobile terminal is the first time to insert the mobile terminal. Other judgment standards are used, and the embodiment does not limit this, as the case may be.

It should also be noted that when the user manually sets the call forwarding state through the mobile terminal, the command must be sent to the network by the command, and the call forwarding information returned by the network side must be stored in the mobile terminal or the SIM card. In addition, in order to solve the problem that the user cannot perform the call forwarding setting on the mobile terminal without being synchronized to the mobile terminal in time, for example, using a device such as a computer to perform call forwarding setting on the mobile terminal through the network, the call may be set. The mobile terminal queries the network side every time it is turned on to update the locally stored call forwarding information.

On the basis of any of the above embodiments, the call forwarding status query method provided by an embodiment of the present invention, wherein the mobile terminal is preferably a mobile phone, and when the call forwarding information of the SIM card is stored in the mobile terminal such as the mobile phone In the middle, the SIM card is matched by the ICCID number and the call forwarding information of the SIM card.

When the call forwarding information of the SIM card is stored in a mobile terminal such as a mobile phone, since one mobile phone may insert and store call forwarding information of multiple SIM cards, the current SIM card needs to read the SIM card correspondingly from the local SIM card. For the call forwarding information, the SIM card must be matched with the corresponding call forwarding information. In this embodiment, the SIM card is preferably matched by the ICCID number and the call forwarding information of the SIM card, so that the SIM card can be conveniently and accurately read. Call forwarding information, that is to say, when the mobile terminal such as a mobile phone stores the query result, it uses the ICCID of the SIM card to match and store it. Of course, if the call forwarding information of the queried SIM card is stored in the SIM itself, the above does not involve the above. problem.
