The invention relates to a method where a first address () from a first network () is obtained to a mobile node (). Network address translation information is received from a network node () to the mobile node (), the network node () being connected to a second network (). An address mapping is indicated between the first address () and a second address () to the network node (), the second address () being associated with the second network (). A session establishment request is obtained. The request comprises instances of the first addresses () and third addresses (). The first addresses () are replaced with the second addresses () in the request. An address mapping is indicated between the third address () and a fourth address () to the first network node (). The session establishment request is sent to a remote network node () from the mobile node ().

Method for the establishing of peer-to-peer multimedia sessions in a communication system

An approach is provided for a publish/subscribe mechanism over an ad-hoc mesh network. A module receives a request to either publish or subscribe to information provided over an ad-hoc mesh network. The module then determines at least one data schema associated with the information, wherein an identification of the information for publication or subscription is based, at least in part, on the at least one data schema.

Method and apparatus for providing a publish/subscribe mechanism over an ad-hoc mesh network

A group management framework and methodology for managing symmetric groups using peer-to-peer network communications. Group management is distributed throughout the group members of the peer-to-peer network, and group information is mirrored in each of the members of the group. The framework facilitates management of group member lists, provides group communication capabilities for external applications, and security for the group communication without the need for intermediary servers to provide services.
