At present, with the development of mobile communication, communication becomes more and more convenient, and at the same time, the demand for call restriction is also increasing. For example, the hidden dangers of information security. On the one hand, in terms of personal information security, harassment calls are invincible, and fraudulent calls are repeated one after another, seriously affecting individuals' daily lives and work. On the other hand, the information security of companies and units, especially some classified units, is also greatly threatened. The leaks during the work period continue to occur, causing significant economic losses and other security risks to the unit. Another example is that parents have a mobile phone for their children, but they want their children not to contact other people casually, so as to avoid unexpected things, or to control the child's mobile phone bill, limit the time, location and call objects. .

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart showing an implementation method of a call restriction service provided by the present invention, as shown in FIG. 1:

Step S101: The terminal obtains a call restriction service by issuing a call restriction service request to the network side.

Step S102: The terminal that obtains the call restriction service customizes the call restriction information to the network side, and the network side generates and stores the call restriction information.

The call restriction service includes at least one of the calling restriction service, the called restriction service, and the forward intelligent service. The calling restriction service is used to control the connection call when the terminal is called, and the called restriction service is used to control the connection call when the terminal is called, and the forward intelligent service is used to control the terminal when the call is required to be forwarded. Continue to call.

Step S103: The network side performs the connection call control according to the call restriction information customized by the terminal. When the calling party restricts the service, the network side obtains the call restriction information set by the terminal according to the calling number of the terminal, and if the network side determines that the call cannot be connected according to the call restriction information, the voice is The reason why the terminal cannot be connected is connected. If the network side determines that the call can be connected, the connection call is made, and the call charge is calculated after the call ends, and the call CDR is issued.

When the called restricted service is executed, the network side obtains the call restriction information set by the terminal according to the called telephone number of the terminal, and if the network side determines that the call cannot be connected according to the call restriction information, the voice prompt cannot be connected, if the network side judges If the call can be connected, the call is made, and the cost of the call is calculated after the call ends and the call is issued.

When performing the forward smart service, the network side obtains the call restriction information set by the called terminal according to the called telephone number of the terminal. If the network side determines that the forward call cannot be made according to the call restriction information, the voice prompt cannot be forwarded. If the network side judges that it can forward, it makes a forward call, and calculates the call charge after the call ends and issues the call CDR.

In addition, the functions of the call restriction service include: at least one of incoming black, white list and outgoing black, white list, incoming call restriction time and outgoing call restriction time, and incoming restricted cell and outgoing restricted cell.

Among them, the incoming blacklist and the incoming whitelist can be either a number segment or a specific number. The incoming blacklist user is not allowed to connect to the call when the calling party restricts the service user. The whitelisted user allows the call to be terminated when the calling party restricts the service user.

The blacklist of outgoing messages and the whitelist of outgoing calls can be either a number segment or a specific number. The call is restricted to restrict the service user from making a call to the blacklisted user. The call restriction service user allows the caller to make a call when the caller calls the whitelisted user.

The incoming limit time can be either a specific date or a specific time period per day. When the call restriction service user is within the limited time, other users are not allowed to connect to the call. When the call restriction service user is outside the limited time, other users are allowed to connect to the call.

The outgoing call restriction time can be either a specific date or a specific time period per day. When the call restriction service user is within the limited time, the call to other users is not allowed to connect to the call, and when the call restriction service user is outside the restricted time, the call to other users is allowed. Continue to call.

If the CELLID of the cell in which the call restriction service is currently located is the CELLID of the incoming call restriction cell, the call of the other user is not allowed to be connected. The CELLID of the cell in which the call restriction service is currently located is not the CELLID of the incoming cell restriction, and the call of other users is allowed to be connected. .

The CELLID of the cell in which the call restriction service is currently located is the CELLID of the outgoing call restriction cell, and the outgoing call of the other user is not allowed to be connected. The CELLID of the cell in which the call restriction service is currently located is not the CELLID of the outgoing call restriction cell, and the outgoing call of the other user is called. Allow connection.

Several call restriction factors can use only one of them, for example, only use the blacklist of the outgoing call, or set the priority. For example, the called user appears in the black and white list at the same time. The level is high, the call is allowed, and all or some of these types can be freely combined to make a more flexible call restriction scheme.

FIG. 2 is a schematic diagram showing the system structure of the call restriction service provided by the present invention. As shown in FIG. 2, the system includes a call restriction service subscription module, a call restriction information setting module, a call triggering module, and a service control module.

The call restriction service signing module processes the call restriction service request of the terminal, and signs the call restriction user, and can sign one or several of the caller, the called party, and the forward call. In the general implementation, the HLR of the intelligent network can be used.

The call restriction information setting module sets the incoming black and white list of the user, the outgoing black and white list, the incoming call restriction time, the outgoing call restriction time, and the incoming call restriction cell CELLID and the outgoing call restriction cell CELLID. SMAP can be used in general implementation.

The call triggering module triggers the call restriction intelligent service of the subscription user according to the user subscription information. In general implementation, it is the MSC of the intelligent network.

The service control module includes a call restriction information storage module, a call restriction information determination module, a voice prompt module, a call connection module, and a billing module.

The call restriction information storage module stores information of the call restriction user, including the user number. The incoming black and white list, the outgoing black and white list, the incoming call restriction time, the outgoing call restriction time, the incoming call limit d, the area CELLID and the outgoing call limit d, the area CELLID.

The call restriction information judging module judges whether the user can call the connection according to the call restriction information set by the user in the caller, called, and forward flow of the user.

When the voice prompting module does not allow connection in the calling, called, and forwarding processes of the user, the prompting may not be connected.

The call connection module determines that the call can be connected in the calling, called, and forwarding processes, and then performs a connection call.

The billing module calculates the cost of the call and issues a bill for the call based on the call information.
