In one aspect, a digital processing device includes i) an input unit, inputting a signal, ii) a subscriber identity unit, storing an identity code of a communication operator and generating a communication network access request message, iii) an additional service identity unit, storing an identity code of an additional service operator and generating an additional service request message and v) a control unit, generating a control signal allowing one of the subscriber identity unit and the additional service identity unit to be selectively driven. In accordance with at least one inventive embodiment, a user of the digital processing device can receive an additional service without his or her subscription to a specific communication operator and use various additional services in addition to the additional services provided by the subscribed communication operator. ## Claims ### Claim 1 One or more processor-readable storage devices having processor-readable code, the processor-readable code which, when executed by one or more processors, performs a method of providing an additional service of a mobile communication terminal, the method comprising: receiving a command from a user; transmitting a first identity code and a first authentication information corresponding to a communication operator to a first communication network device corresponding to the first identity code, when the command corresponds to a subscriber identity module; and transmitting a second identity code and a second authentication information corresponding to an additional service operator to an additional service providing device corresponding to the second identity code via the first communication network device in one case and via a second communication network device which does not correspond to the first identity code in another case, when the command corresponds to an additional service identity module; wherein the subscriber identity module includes the first identity code and the first authentication information and the additional service identity module includes the second identity code and the second authentication information, and wherein the communication operator provides a communication service, and the additional service operator provides an additional service including at least one of a video game, a music and a broadcasting program. ### Claim 2 (depends on 1) The storage device of claim 1, wherein the second identity code includes at least one of a uniform resource locator (URL) and an IP address of the additional service providing device. ### Claim 3 (depends on 1) The storage device of claim 1, wherein the subscriber identity module is installed in a form of a card detachable from the mobile communication terminal, and the additional service identity module is installed in a form of a program in the mobile communication terminal. ### Claim 4 (depends on 3) The storage device of claim 3, wherein the additional service identity module is installed in the mobile communication terminal external to the card. ### Claim 5 (depends on 1) The storage device of claim 1, wherein the first authentication information is transmitted to the communication network device for the communication network device to perform an authentication process based on the first authentication information, and the second authentication information is transmitted to the additional service providing device for the additional service providing device to perform an authentication process based on the second authentication information. ### Claim 6 A communication system comprising: a mobile communication terminal including a subscriber identity module configured to store an identity code of a communication operator, and a subscriber authentication information related to the communication operator, the communication operator providing communication service, and an additional service identity module configured to store an identity code of an additional service operator, and a subscriber authentication information related to the additional service operator; and an additional service providing device corresponding to the identity code of the additional service operator, and configured to provide an additional service to the mobile communication terminal, wherein, when the additional service identity module is driven, the mobile communication terminal communicates with the additional service providing device via a communication network device which corresponds to the identity code of the communication operator in one case and via a further communication network device which does not correspond to the identity code of the communication operator in another case, and wherein the additional service includes at least one of a video game, a music and a broadcasting program. ### Claim 7 (depends on 6) The communication system of claim 6, wherein the identity code of the additional service operator includes at least one of a uniform resource locator (URL) and an IP address of a web server of the additional service operator. ### Claim 8 (depends on 6) The communication system of claim 6, wherein the subscriber identity module is installed in a form of a card detachable from the mobile communication terminal, and the additional service identity module is installed in a form of a program in the mobile communication terminal. ### Claim 9 (depends on 8) The communication system of claim 8, wherein the additional service identity module is installed in the mobile communication terminal external to the card. ### Claim 10 (depends on 6) The communication system of claim 6, wherein the mobile communication terminal transmits a communication network access request message including the identity code of the communication operator, when the subscriber identity module is driven. ### Claim 11 (depends on 6) The communication system of claim 6, wherein the mobile communication terminal transmits a communication network access request message including the identity code of the communication operator, when the mobile communication terminal receives a command of making a call. ### Claim 12 (depends on 6) The communication system of claim 6, wherein the mobile communication terminal transmits an additional service request message including the identity code of the additional service operator, when the additional service identity module is driven. ### Claim 13 (depends on 6) The communication system of claim 6, wherein the mobile communication terminal communicates with the communication network device, when the subscriber identity module is driven. ### Claim 14 (depends on 6) The communication system of claim 6, wherein the mobile communication terminal transmits the subscriber authentication information related to the communication operator to the communication network device for the communication network device to perform authentication process based on the subscriber authentication information related to the communication operator, when the subscriber identity module is driven. ### Claim 15 (depends on 6) The communication system of claim 6, wherein the mobile communication terminal transmits the subscriber authentication information related to the additional service operator to the additional service providing device for the additional service providing device to perform authentication process based on the subscriber authentication information related to the additional service operator, when the additional service identity module is driven.
