IMPROVED SESSION SETUP IN AN ENERGY-EFFICIENT CELLULAR WIRELESS TELECOMMUNICATIONS SYSTEM |
摘要 |
The present invention provides a random access procedure for establishment of a data connection between a terminal and a SA-cell in an energy-efficient network, such as e.g. a BCG2 network, wherein the total session setup time is shortened. An information request message (IRM) transmission from the mobile terminal is used for selecting the SA-cell that will serve the mobile terminal (i.e. set-up a data session with this SA-cell) and is simultaneously used for performing a 'contention-free-like' random-access procedure towards all candidate SA-cells. In this way performing a RACHSA procedure after selecting a SA cell becomes unnecessary, the random access time is shortened and the uplink resources (at the selected SA-cell) and the uplink transmissions from the terminal are more effectively used. |
