Popis: This paper describes the presence service which is located in the IP multimedia subsystem (IMS). This service allows creation of many applications for different groups of people. This paper describes the number of transmitted messages in the network intended for users who track statuses of other users. Apart from the number of the messages it also deals with the composition of these messages. Here we describe the difference between these models of communication. Specifically we talk about the push model, the pull model and the combined model. We compare these models and choose which to use and when.
