Security protocols for mobile operator networks

摘要

Security protocols for mobile operator networks are described. In embodiments, mobile communication link is established between a mobile phone and a media content provider via a communication service provider with which the mobile phone is registered for mobile communications, and via at least one roaming node network with which the communication service provider has a roaming service agreement. The media content provider receives a security policy request from the mobile phone to establish a security policy for end-to-end security of the mobile communication link between the media content provider and the mobile phone for data communication security. The media content provider then communicates a security policy response to the mobile phone to establish the security policy for the end-to-end security of the mobile communication link that is adaptable to security restrictions of the roaming node network.
