REDUCING SIGNALING IN RNSAP PROTOCOL UPON CELL CHANGE IN CELLULAR TELECOMMUNICATIONS NETWORK

摘要

IN A CELLULAR TELECOMMUNICATIONS SYSTEM, WHEN A USER EQUIPMENT UNIT (UE) [30] SEEKS TO USE A FACH COMMON TRANSPORT CHANNEL IN A CELL CONTROLLED BY THE DRIFT RADIO NETWORK CONTROLLER (DRNC) [26²], THE DRIFT RADIO NETWORK CONTROLLER (DRNC) SIGNALS TO A SERVING RADIO NETWORK CONTROLLER (SRNC) [261] WHETHER THE DRIFT RADIO NETWORK CONTROLLER (DRNC) REQUIRES INITIATION OF A COMMON TRANSPORT CHANNEL RESOURCE INITIALIZATION PROCEDURE. IF THE SIGNALING INDICATES THAT THE DRIFT RADIO NETWORK CONTROLLER (DRNC) DOES NOT REQUIRE INITIATION OF THE COMMON TRANSPORT CHANNEL RESOURCE INITIALIZATION PROCEDURE, THE SERVING RADIO NETWORK CONTROLLER (SRNC) HAS DISCRETION WHETHER TO INITIATE THE COMMON TRANSPORT CHANNEL RESOURCE INITIALIZATION PROCEDURE WITH RESPECT TO THE USER EQUIPMENT (UE) IN THE CELL.
