Abstract

The present disclosure provides a method for blocking crank calls by using cloud computing and a system thereof. In the method, a client(s) uploads a blacklist to a server; the server makes statistic according to blacklist data uploaded by the client(s) and determines a particular phone number be a crank phone number, generates an anti-crank policy and updates the generated anti-crank policy to the client(s); when receiving a call or a message from the crank phone number, the client executes the anti-crank policy.

Claims

1. A method for blocking crank calls by using cloud computing, the method comprising:

sending a blacklist to a server by a client;

making statistics according to blacklist data uploaded by the client;

determining that a particular phone number is a crank phone number;

generating an anti-crank policy and updating the generated anti-crank policy to the client by the server;

when receiving a call or a message from the crank phone number, the client giving an alert that the phone number is a crank phone number;

wherein the making statistics according to the blacklist data uploaded by the client and determining the particular phone number as a crank phone number by the server comprises;

in a predetermined time period T, when a number of times that a phone number is added in the blacklist by users of a region exceeds threshold value Mx, the phone number is defined as a crank phone number of the region; and

in a predetermined time period T, when a phone number is added in the blacklist by users of more than N regions and weighted average of a number of times that the phone number is added in the blacklist by the users of the N regions exceeds threshold value My, the phone number as defined as a national crank phone number;

wherein the method further comprises;

storing an intercepting record and uploading the intercepting record to the server by the client;

making statistics by the server according to the intercepting record uploaded by the client; and

determining that the particular phone number is the crank phone number and generating the anti-crank policy,

wherein the making statistics by the server according to the intercepting record uploaded by the client comprises;

in the predetermine time period T, when the number of times that a phone number is added in the blacklist by users of a region exceeds threshold value Nx, the phone number is defined as a crank phone number of the region; and

in the predetermined time period T, when a phone number is added in the intercepting record by users of more than N regions and a weighted average of a number of times that the phone number is added in the intercepting record by the users of the N regions exceeds threshold value Ny, the phone number is defined as a national crank phone number.

2. The method of claim 1, further comprising

adding a phone number of a crank call or a crank short message in the blacklist by the client via selection of the user.

3. The method of claim 1, wherein updating the generated anti-crank policy to the client comprises

arranging a regional crank phone number in a blacklist of a client of the region;

arranging a national crank phone number in the blacklists of all clients of a country;

executing the anti-crank policy comprises giving weak alert for a crank call or a crank short message, automatically refusing a crank call or a crank short message and/or giving an alert to the users that a call or a short message is the crank one.

4. The method of claim 1, wherein the intercepting record includes at least one of:

a record that the client intercepts a call, which is cut off immediately after call ringing;

an intercepting record set by the user manually; and

a call refused by the users of a region.
