Problems solved by technology

[0010] Yet another problem is that when users replace their current mobile terminal SIM with a new SIM, even if the new SIM is related to a subscription to the same network operator, they cannot render content that requires an RO bound to their IMSI to render
In this case, although the user still has a subscription to the same operator, the user is no longer able to reproduce already purchased content
This situation is not only disadvantageous for users, but also disadvantageous for operators, because operators cannot provide convenient and attractive services to users

Embodiment Construction

[0032] figure 1 A block diagram of a user equipment (UE) 100 according to an embodiment of the present invention is shown. The UE 100 may be implemented in various electronic devices, such as mobile phones, personal computers, and the like.

[0033] UE 100 includes a digital rights management (DRM) agent 110 . The DRM agent 110 includes: a content acquisition unit 111 , a reception unit 112 , a detection unit 113 , a key acquisition unit 114 , a determination unit 115 , and a reproduction unit 116 . It should be noted that the function of each block in the DRM agent 110 may be implemented using dedicated hardware, using software executed by a processor (not shown), or a combination thereof.

[0034] The content acquisition unit 111 is configured to function as a content browser, and acquires content items (for example, audio files, video files, etc.) from the content server 200 . Alternatively, the content acquisition unit 111 may not function as a content browser. In this...

Abstract

There is provided a User Equipment comprising: a content obtaining unit that obtains a content item that is not reproducible without permission data for enabling reproduction of the content item; a receiving unit that receives the permission data; a detecting unit that detects that the permission data indicates that a subscriber of a predetermined network operator is entitled to reproduce the content item using the permission data; a key obtaining unit that obtains key data from a module managing subscription information for the predetermined network operator by sending, to the module, information representing the predetermined network operator and information representing an authentication server for determining validity of the key data; a determining unit that determines whether or not the key data is valid by communicating with the authentication server; and a reproducing unit that reproduces the content item using the permission data if it is determined that the key data is valid.

Description

technical field [0001] The present invention generally relates to a user equipment and a control method of the user equipment. Background technique [0002] The Open Mobile Alliance (OMA) released an approved enabler for Digital Rights Management Version 2.0 (OMADRM2.0) on March 3, 2006. The OMADRM2.0 enabler version defines the protocols, messages and mechanisms required to implement a DRM system in a mobile environment. [0003] As in other similar DRM systems, in OMADRM2.0, protected content is delivered to user devices and can be consumed along with a specific Rights Object (RO). The RO can be obtained over the network in a secure manner. This acquisition mechanism is specified as Rights Object Acquisition Protocol (ROAP), and it involves two important OMADRM2.0 entities: "Device" and "Rights Issuer". [0004] According to Section 15.1 of OMADRM Specification Version 2.0, OMADRM 2.0 supports binding RO to International Mobile Subscriber Identity (IMSI). By binding th...
