Abstract:
1. Method for routing a Radio Resource Control message (RRC), previously sent by a terminal on the common control channel CCCH of a cell, from a Cell Control (CC) being responsible for controlling functions related to the cell and for terminating control channels associated with said cell and said Cell Control being associated to said cell to a Mobile Control (MC)of a distributed Radio Network Controller equipment of a Radio Access Network to which the terminal is associated, wherein said mobile control is dynamically created when a new signaling connection known as radio resource control RRC connection is established for a particular user, the method comprising the steps of: 1a) Previously establishing a Radio Resource Control communication between the terminal and the Radio Access Network resulting in that the Mobile Control is instantiated and both said Mobile Control and the terminal are configured with an identifier USER-ID, as well as an identifier PP&B-ID of a parent paging and broadcasting associated to the Mobile Control, these identifiers being used to uniquely identify the terminal in further Radio Resource Control RRC messages; 1b) Sending the Radio Resource Control message from the terminal via a Common Control Channel of the cell where the terminal is located to the Cell Control associated to said cell within said Radio Access Network; 1c) Forwarding the Radio Resource Control message from the Cell Control to a paging and broadcast associated to said Cell Control; and 1d) Forwarding the Radio Resource Control message from the paging and broadcast associated to the cell control to the Mobile Control identified by the USER-ID in the case that the paging and broadcast associated to the cell control associated to the cell control corresponds to the parent paging and broadcast.
