Systems and methods for filtering cellular telephone messages

Abstract

Systems and methods for filtering cellular messages to prevent receipt of certain messages are described. In one aspect, a computing device detects an incoming cellular telephone message for delivery to a receiver. The device filters the message by determining source identification information for the incoming cellular telephone message. The device compares this information to source identification entries in an acceptable senders list. The acceptable senders list includes source identification information corresponding to previous incoming and outgoing voice contacts by the receiver. If the source identification information for the incoming cellular telephone message is not found in the source identification entries in the acceptable senders list, the device deletes the cellular telephone message from a memory to prevent receipt of the message by the receiver.

1 . A method implemented by a computing device for preventing delivery of certain cellular telephone messages, the method comprising:
 filtering cellular telephone messages by:
 detecting an incoming cellular telephone message for delivery to a receiver; 
 determining source identification information for the incoming cellular telephone message; 
 comparing the source identification information for the incoming cellular telephone message with source identification entries in an acceptable senders list, the acceptable senders list comprising source identification information corresponding to previous incoming and outgoing voice contacts by the receiver; and 
 if the source identification information for the incoming cellular telephone message is not found when comparing the source identification entries in the acceptable senders list, deleting the cellular telephone message from a memory to prevent delivery of the cellular telephone message to the receiver. 
   
     
     
         2 . The method of  claim 1 , wherein the acceptable senders list is automatically determined by call records maintained by a cellular telephone service provider. 
     
     
         3 . The method of  claim 2 , wherein the acceptable senders list is automatically updated upon receiving notification of an incoming or outgoing voice contact by the receiver. 
     
     
         4 . The method of  claim 1 , wherein the source identification entries in the acceptable senders list comprise source identification information corresponding to incoming and outgoing voice contacts by the receiver above a predetermined duration. 
     
     
         5 . The method of  claim 1 , wherein source identification entries in the acceptable senders list are removed from the acceptable senders list corresponding to incoming and outgoing voice contacts by the receiver not contacted within a predetermined duration. 
     
     
         6 . The method of  claim 1 , wherein the acceptable senders list further comprises additional acceptable source identification information manually entered and maintained by the receiver. 
     
     
         7 . The method of  claim 6 , further comprising adding the additional acceptable source identification information to the acceptable senders list. 
     
     
         8 . The method of  claim 1 , wherein the acceptable senders list further comprises additional undesirable source identification information manually entered and maintained by the receiver that causes deleting of the cellular telephone message. 
     
     
         9 . The method of  claim 8 , further comprising removing the additional undesirable source identification information from the acceptable senders list. 
     
     
         10 . The method of  claim 1 , further comprising providing a notification to the receiver of the deleting of the cellular telephone message. 
     
     
         11 . The method of  claim 1 , further comprising providing notification to a sender of the cellular telephone message of the deleting of the cellular telephone message. 
     
     
         12 . The method of  claim 1 , further comprising delivering the cellular telephone message if the source identification information for the incoming cellular telephone message matches an entry in the acceptable senders list. 
     
     
         13 . A data processing system for preventing delivery of cellular telephone messages, the data processing system comprising:
 a data processing device comprising a processor and a memory; and   wherein the data processing device detects an incoming cellular telephone message, determines the telephone number of the incoming cellular telephone message, compares the telephone number of the incoming cellular telephone message with the telephone numbers of incoming and outgoing voice contacts with a receiver in an acceptable senders list comprising telephone numbers of incoming and outgoing voice contacts with the receiver, rejects the incoming cellular telephone message if the telephone number for the incoming cellular telephone message is not found in the acceptable senders list, and deletes the incoming cellular telephone message from a memory to prevent delivery of the incoming cellular telephone message to the receiver.   
     
     
         14 . The data processing system of  claim 13 , further comprising a database in communication with the data processing device, and wherein the database stores the acceptable senders list. 
     
     
         15 . The data processing system of  claim 13 , wherein the data processing device is located within a wireless network. 
     
     
         16 . The data processing system of  claim 13 , wherein the data processing device is located at a centralized location. 
     
     
         17 . A computer readable data storage medium comprising computer-program instructions executable by a process, the computer-program instructions, when executed by the processor, for implementing steps comprising:
 monitoring source identification information for incoming and outgoing voice communications over a wireless network for a receiver;   adding source identification information for the incoming and outgoing voice communications to the receiver to an acceptable senders list for the receiver;   detecting an incoming cellular telephone message;   determining the source identification information of the incoming cellular telephone message;   comparing the source identification information of the incoming cellular telephone message with the source identification information in the acceptable senders list to determine matches;   rejecting the cellular telephone message if the source identification information for the cellular telephone message is matched in the acceptable senders list; and   deleting the cellular telephone message from a memory to prevent delivery of the cellular telephone message to the receiver.   
     
     
         18 . The computer readable data storage medium of  claim 17 , further comprising incorporating additional acceptable source identification information, manually entered and maintained by the receiver, into the acceptable senders list. 
     
     
         19 . The computer readable data storage medium of  claim 17 , further comprising removing additional undesirable source identification information, manually entered and maintained by the receiver, from the acceptable senders list. 
     
     
         20 . The computer readable data storage medium of  claim 17 , further comprising delivering the cellular telephone message if the source identification information for the incoming cellular telephone message is matched on the acceptable senders list.
