Abstract
Techniques for managing entities identified by presence information in a communications network are provided. A condition expressing one or more predicates over one or more presence attributes in the communications network is received. A dynamic entity is generated, wherein the dynamic entity allows at least one user to subscribe thereto. The dynamic entity comprises at least one entity identified by presence information when it is determined that the at least one entity satisfies the condition. The generated dynamic entity is managed by either or both of: (i) adding to the dynamic entity at least another entity identified by presence information that satisfies the condition; and (ii) removing from the dynamic entity an entity identified by presence information that no longer satisfies the condition.
