System, network entity, terminal, method, and computer program product for presence publication

摘要

A system for presence publication, such as in a push-to-talk over cellular service, provides means for avoiding the reporting of conflicting presence information to a presence server. Two different entities may be capable of reporting status information for the same entity, the status information corresponding to a plurality of status attributes. The first entity would typically inform the second entity which ones of the plurality of status attributes for which the first entity will be reporting status information to the presence server. For the ones of the plurality of status attributes for which the first entity will be reporting status information, the second entity will typically not report status information. For the ones of the plurality of status attributes for which the first entity will not be reporting status information, the second entity will typically report status information if capable.
