<p>PROBLEM TO BE SOLVED: To provide a terminal management system and a method capable of reducing a calculation amount when a context information group having high similarity is extracted from pieces of context information collected in a long-term.SOLUTION: A terminal management system 1 comprises: plural terminals 50; and a terminal management device 10. The terminals 50 acquire an index number corresponding to acquired positional information based on an index storage part 55, and transmits collection information including context information and the index number with the identification information of the terminals 50 to the terminal management device 10. The terminal management device 10 makes the context information of the received collection information correspond to the identification information of each terminal 50, and makes the index number of the collection information correspond to the context information to which the identification information of the terminal 50 is corresponded, and stores it in a context information storage part 11. Then, the terminal management device 10 compares pieces of context information having same index numbers each other corresponding to the context information, and extracts the pieces of context information which are similar.</p> |
