Improved systems and methods for establishing peer-to-peer calls such as voice over IP calls and video over IP calls. In various embodiments of the invention, SMTP messages are exchanged between devices using a SMTP server, with the SMTP messages including IP address information. With this arrangement, the need for SIP service providers can be eliminated. In other embodiments of the present invention, SMS messages including IP address information are transmitted between devices during a GSM or other type of telephone call, enabling the call to 'migrate' to a VoIP or video over IP call.

Systems for providing peer-to-peer communications

A system and method for enforcing digital rights management (DRM) rules in a terminal, even when the requesting rendering application is already operating. Content, which may be encrypted, is received at the terminal and securely stored. On-demand authorization is effected for the rendering application that is requesting access to the content, using secure communications between a DRM engine within the terminal and an operating system within the terminal that is augmented with a security manager adapted to engage in such secure communications. If the rendering application is found to be authorized, the DRM rules are applied to determine whether the rendering application may access the content, and if so, the content is made available to the rendering application.

System and method for dynamically enforcing digital rights management rules

Apparatus, and an associated method, forms an integrated packet radio communication system. An integrated system is formed of portions of a GPRS system as well as portions of a WLAN system, such as that defined in the IEEE 802.11 standard. A WIP (WLAN Integrated Protocol) layer is defined, functionally positioned between upper-level, GPRS layers and lower-level, WLAN layers. Advantages of a GPRS system as well as advantages of the WLAN system are maintained in the integrated system.
