METHOD AND SYSTEM FOR CONTROLLING A REAL-TIME COMMUNICATIONS SERVICE

摘要

A real-time media session is between user equipment and a media communication server via a serving access network. According to the invention, dummy data (e.g. a dummy message) is sent in order to maintain a dedicated channel during inactive periods of a real-time media session or to trigger an early setup of a dedicated channel in the access network. Thereby, user equipments that are logged on to a real-time media (e.g. PoC) session are prevented form going to a radio resource idle state, and therefore potential long extra delays during real time media (e.g. PoC) service usage avoided. The invention further allows the sending and receiving user equipments to set up their dedicated channels (DCH) already during the start to talk procedure of the transmitting user equipment, which in turn potentially reduces end-to-end delays during the conversation.
