ABSTRACT:
A group advertisement method in a SIP (Session Initiation Protocol) based message service, and a PT client device are discussed. According to an embodiment, the method includes receiving, by a PT server, a request to send a group advertisement message for a specific PT group from a requesting PT client; determining, by the PT server, if the specific PT group is a restricted chat group or a pre-arranged group; determining, by the PT server, if the requesting PT client is allowed to send a group advertisement based on a PT group document associated with the specific PT group; and selectively transmitting, by the PT server, the group advertisement message to at least one member of the specific PT group based on results of the determining steps.
