FIELD: information technology.
SUBSTANCE: invention provides instant messaging (IM) mixed mode operation by utilising page mode IM and session based IM jointly in the same IM conversation. According to the invention, an application initiates an IM conversation between a sending user registered at a sending device and a remote user registered at multiple devices initially in page mode. After discovering the identity of a remote device used by the remote user to initially reply to the IM conversation, the application converts the IM conversation from page mode IM to session based IM.
EFFECT: more efficient messaging for multiple points of presence owing to use of an instant messaging model.
