Description

A Subscriber Identification Card and Its Method for Implementing Call Restriction

technical field

The invention relates to the technical field of communication, in particular to a subscriber identification card and a method for realizing call restriction.

Background technique

With the rapid development of modern communication technology, especially the growth of wireless terminal services, operators are constantly launching various special services to enhance their own competitiveness. Generally, enterprise users have a large amount of communication business. In order to attract enterprise users, operators generally set lower tariffs, and can provide services that limit users to use within a certain area or within a certain period of time. business. This service can be widely used in some enterprises and institutions. For example, enterprises and institutions can use cheap mobile services to replace fixed-line telephone services. At the same time, it can achieve the purpose of limiting the scope of use of employees, that is, restricting employees to work only in the unit or during working hours. use. All of the above restrictions on the scope of use of users can be achieved by restricting calls.

Call restriction methods in the prior art include:

1. A method for restricting mobile terminal calls through the network side. The mobile terminal obtains the call restriction service by sending a call restriction service request to the network side; the terminal obtaining the call restriction service customizes the call restriction information to the network side, and the network side generates and saves the call restriction information; Continue call control.

2. A method for implementing call restriction on a mobile terminal. When a user initiates a call, the mobile terminal controls whether the user can initiate a call request to the network according to the pre-set call restriction conditions.

The above methods all have their drawbacks. Although method 1 can effectively limit the scope of use of the subscriber identification card, for the operator, this method requires the network side to specially set up a control center and store a large amount of user control information. In addition, the operator also needs a dedicated staff to maintain the service. These require additional capital investment. For the user, this restriction method depends on the operator. If the user wants to change the service, he needs to submit an application for handling the service to the operator, and it will not take effect until the operator completes the corresponding operation. This prolongs the cycle of service change, and the user cannot change the calling authority of the terminal at any time. Method 2 is completely controlled by the mobile terminal. If the user identification card is replaced with another ordinary terminal, the call restriction function will be invalid. In this method, the user identification card and the terminal must be bound to make the call restriction function effective.

When the subscriber identity card detects that the terminal does not meet the preset call restriction condition according to the acquired local state information of the terminal, it deactivates the FDN function and notifies the terminal that the current call is not restricted.

A preferred embodiment of the present invention is given below according to FIG. 2 to FIG. 3 , and the technical details of the present invention are further given in conjunction with the description of the embodiment.

As shown in Figure 2, the subscriber identity card provided in the embodiment of the present invention realizes the method for call restriction, comprises the following steps:

Step S201: Set the call restriction conditions of the subscriber identity card.

Specifically, this step can be realized in the following ways:

(1) During the start-up process of the terminal, the subscriber identification card sends an active command SETUP MENU (setup menu command) to the terminal to provide the user with a call restriction setting menu;

(2) After the user selects the menu, the user identification card asks the user to set the password through the GET INPUT (obtain input command) command;

(3) After the password input by the user is verified, the user identification card can provide the user with options to set the restricted area, restricted time and unrestricted number list through the SELECT ITEM (select item command) command for the user to set.

Step S202: the subscriber identity card periodically sends a command to the mobile terminal to ask for the terminal's local state information.

Specifically, in this step, the subscriber identity card asks the mobile terminal for local state information through an active command PROVIDE LOCALINFORMATION (command to provide local state information); wherein, the local state information includes terminal location information and current time information.

Step S203: the terminal sends local state information to the subscriber identity card.

Specifically, in this step, the terminal responds to the proactive command PROVIDE LOCALINFORMATION, and sends the location information and current time information to the subscriber identification card through the TERMINAL RESPONSE (terminal response command) command.

Step S204: the subscriber identity card receives and analyzes the local state information of the terminal.

Specifically, the subscriber identity card receives the TERMINAL RESPONSE command and parses out the current location information and time information of the terminal from the local state information.

Step S205: the subscriber identity card judges whether to activate the call restriction according to the local state information of the terminal and the set call restriction condition.

Specifically, the subscriber identification card judges whether the current location and/or time of the terminal exceed the preset location area range and/or time range; Activate the FDN function.

Step S206: when the call barring is activated, the subscriber identity card notifies the mobile terminal.

Specifically, when the FDN function is activated, the subscriber identity card sends an active command REFRESH (refresh command) to the terminal to inform the terminal that the phonebook information has changed, and the mobile terminal responds to the command and updates its own phonebook status.

At the same time, the user identification card gives prompt information to the user through the active command PUT IDLE TEXT (the idle interface displays the text command), and the terminal responds to the command and displays the prompt information on the IDLE interface. Such as: exceeding the service area; or exceeding the service time; or exceeding the service scope, etc.

Step S207: The terminal restricts calls according to the control state of the subscriber identity card.

That is, if the FDN function is currently activated, the user can only call the numbers in the FDN list, and other numbers cannot make calls.

Step S208, when the subscriber identity card detects that the terminal does not satisfy the set call restriction condition according to the local state information of the terminal, deactivate the call restriction.

That is, the FDN function is deactivated, and at this time, the user's calls are not restricted.

To sum up, in this embodiment, the subscriber identification card sets call restriction conditions through command interaction with the terminal, and judges in real time whether the terminal exceeds the limit range through custom command queries, and if it exceeds the limit range, the FDN function is automatically activated to achieve The purpose of restricting calls by the terminal to the user. If the terminal returns to the limited range, the FDN function will be automatically deactivated, and the user's call will return to normal. Wherein, the specific command interaction is shown in FIG. 3 .

It should be noted:

In the embodiment of the present invention, the limitation function of the time range of the subscriber identification card is applicable to the terminal synchronized with the system time;

In the embodiment of the present invention, the restricted area setting of the above-mentioned user identification card may also be automatically generated and saved on the user identification card according to the initial movement range of the terminal. And the user can clear it through the S(U)TK(SIM ToolKit) menu;

In the embodiment of the present invention, for the setting of call restriction conditions, the subscriber identification card can judge whether the terminal supports the S(U)TK menu command used by it according to the TERMINAL PROFILE (terminal profile command) command in the terminal startup process, if not Service may be refused.

It can be seen that the method of the present invention does not need to set up a control center on the network side, and does not need operators to specially set up staff to carry out service maintenance. It only needs to require the card dealer to add a call restriction control module in the card when issuing the subscriber identification card. , the subscriber identification card asks for the current location information and time information by sending active commands to the terminal, and activates or deactivates the FDN function according to the current information and the preset area limit and time limit information, and notifies the mobile terminal of the control status in time, the mobile The terminal restricts the number dialed by the user through the FDN function. The user can also update the control conditions at any time through the password without submitting a service change application to the operator and waiting for processing. It can be seen that the method of the present invention not only solves the problem of inconvenient business management caused by the use of network side control in the prior art, but also, the present invention mainly uses the user identification card to control the call restriction, no matter how the user changes the terminal, the call restriction function will not It can be performed normally, and further solves the problem in the prior art that the call restriction function is invalid when the subscriber identification card is replaced by the terminal using the terminal to control the call restriction.

Further, the control module 430 specifically includes:

The FDN function detection module 431 is used to detect whether the current fixed dialing FDN function is activated when the terminal meets the preset call restriction conditions, and if not activated, activate the FDN function; if activated, do not act.

The notification module 432 is configured to notify the terminal to use the number information in the preset FDN list as the current phonebook information of the terminal when the FDN function is activated.

Further, the FDN function detection module 431 is also used to deactivate the FDN function when the terminal does not meet the preset call restriction condition after the control module 430 triggers the terminal to enter the call restriction state;

The notification module 432 is also configured to notify the terminal that the current call is not restricted when the FDN function is deactivated.

In order to more clearly illustrate the specific functions of the subscriber identification card of the present invention, a detailed description will be given below through a specific embodiment, specifically as follows:

In the embodiment of the present invention, the subscriber identification card includes the following modules:

(1) Set the module;

Provide an interface for users to set restrictions.

This module provides the user with an interface for setting call restriction area, restriction time, and unrestricted number list information through the S(U)TK menu through command interaction with the terminal. The setting module can be further divided into a sending module and a receiving module. Among them, the sending module is used to send active commands to the terminal to realize the setting function, and the receiving module mainly receives the response command TERMINAL RESPONSE from the terminal, which respectively includes the restriction condition information set by the user.

(2) storage module;

Save the password set by the setting module and the restrictive condition information set by the user. The restrictive condition information includes location area, time period, unrestricted number list, etc.

(3) information acquisition module;

This module is used to obtain the location information and time information of the current terminal. It is further divided into a sending module and a receiving module. The sending module is mainly responsible for regularly sending the proactive command PROVIDE LOCALINFORMATION to the subscriber identification card, and requesting local information from the mobile terminal, including the current location information and time information of the mobile terminal. The receiving module mainly receives the local information returned from the mobile terminal and parses the current location information and time information contained therein.

(4) detection module;

It mainly detects and judges whether to activate or deactivate the FDN function according to the current location and time information acquired by the information acquisition module and the restriction condition information stored in the storage module.

Specifically, the detection module detects whether the current location or time exceeds a preset location area range or time range.

(5) Control module;

It is used to detect whether the current FDN function is activated when the detection module detects that the terminal exceeds the set location area range or time range, and if it is not activated, the FDN function is automatically activated;

And, it is used to deactivate the FDN function when the detection module detects that the terminal returns to the set location area range or time range.

(6) notification module;

Mainly responsible for notifying the mobile terminal in time when the control state in the subscriber identification card changes so that the mobile terminal can update accordingly and give user prompts;

Specifically, if the FDN function state changes, the notification module sends an active command REFRESH to the terminal to inform the terminal that the phonebook information has changed, and the terminal responds to the command and updates its own phonebook status. At the same time, the user identification card gives prompt information to the user through the active command PUT IDLE TEXT, and the terminal responds to the command and displays the prompt information on the IDLE interface.

Each of the above modules completes the judgment of the call restriction state through the cooperation between the modules and the command interaction with the terminal, and can notify the mobile terminal in time to realize the call restriction function.

In the present invention, the subscriber identification card obtains the current location and time information by sending commands to the terminal, and judges whether to activate the FDN function according to the preset location range and time range to realize the function of restricting calls to the user's location and time range.

The present invention implements call restriction through the user identification card, without the participation of the operator on the network side, and only needs the card dealer to add a control program in the card when issuing the user identification card, and the user can also update the control conditions at any time through the password. In the present invention, the calling is mainly controlled by the user identification card through the basic command interaction with the terminal, and the calling restriction function can be performed normally when the user replaces the terminal. Therefore, the problem of inconvenient service management in the prior art and the problem of invalidation of the call restriction function when the user identification card is replaced and the terminal is used are solved. Therefore the present invention has very strong practical value and implementation value.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
