  • Patent number: 8190138
    Abstract: Mobile phone 300 is registered with various types of specific keywords. When receiving an e-mail from an external terminal, mobile phone 300 determines whether the e-mail contains a specific keyword. When it is determined that the e-mail contains the specific keyword, mobile phone 300 generates log data containing the specific keyword. Mobile phone 300 then transmits the generated log data to a predetermined transmission destination (such as communication management server 700).

  • Patent number: 8161068
    Abstract: An access control system and method is disclosed. The access control system and method includes a terminal and a server. The terminal determines whether to allow access to a requested website and generates a request to the server to download information from the requested website if the terminal determines to allow access. The server determines whether to allow the terminal access to the requested website and provides information from the requested website to the terminal. The server examines the request to determine whether or not the terminal has made a determination whether to allow access to the requested website. The terminal and server work in combination to determine whether to grant access to the requested website. And the server's determination whether to allow the terminal access is dependent on the server's determination of whether or not the terminal has made a determination whether to allow access to the requested website.

  • Patent number: 7180983
    Abstract: There is provided a guidance information notification apparatus in a communication network system which enables improvement of convenience to a user by dispensing with a particular operation other than a normal origination operation required when a user obtains a guidance message in an understandable language such as a native language, with a terminal unit, and by enabling the user to receive support from a communication operator of the user's contract network even when a roaming service is provided. If an originator inputs a destination telephone number with a normal origination operation at a mobile telephone set 18, a guidance information notification apparatus 22-1 notifies guidance message information in a language associated with the origination telephone number to the origination mobile telephone set 18.

  • Patent number: 7120469
    Abstract: An internal memory has an address book table for registering data regarding a communication destination party, a telephone number, and a country flag indicative of a country where the communication destination party is present, in a manner that they are shown corresponding to one another. A calling processor compares a country flag attached to a communication destination party selected using a memory dial function, and information obtained from an RF module regarding a country where the communication circuit can be established. When the flag information and the information from the Rf module coincide, the calling processor determines that the ongoing call is a domestic call, and thus dials the telephone number as registered in the address book table and, when they do not coincide, the calling processor determines that the ongoing call is an international call, and thus dials international access and country codes prior to the telephone number registered in the address book table.
