DELIVERING CONTENT IN MULTIPLE AREAS USING HIERARCHICAL AREA IDENTIFIERS

Abstract:

A method for delivering content. In some embodiments, the method includes a network node adding a first area identifier, AI, to a set of AIs and, after adding the first AI to the set of AIs, determining that an optimized set of AIs should be created. The network node then performs a process for producing the optimized set of AIs, where the process includes: removing from the set of AIs a certain subset of AIs and adding to the set of AIs a second AI. The network node transmits to a second network node a message comprising information identifying each AI included in the optimized set of AIs.
