DETERMINING A LOCATION ADDRESS FOR SHARED DATA

摘要

A method and apparatus for determining a location address for shared packet switched data. The data is to be accessible by a user of a first device and a user of a second device. A symmetric function is applied to a known identifier associated with the first device and a known identifier associated with the second device. The result of the function can then be used as an address for data to be accessible by users of both the first device and the second device, the data being stored on a remote server at a location defined by the address. The method ensures that the same address is calculated regardless of which identifier is used first, and that both devices can calculate the address without requiring any further signalling or capability/discovery mechanism.
