Abstract
The invention provides for a method of selecting a Dedicated Core Network (DCN) based on assisting indication by mobile terminals, and including the step of configuring the RAN Nodes of the mobile network with the DCN Types of the serving EPC Nodes so that the RAN Nodes can map the DCN selection assisting information from the connecting mobile terminals with the right dedicated EPC Node. This allows for the RAN Node to connect the mobile terminals with EPC Node of the mobile terminal's dedication at initial attach and then keep the mobile terminals on the same DCN. Thus, a re-routing of mobile terminals NAS message from one EPC Node to another EPC node is avoided. The invention also allows for a flexible and dynamic change of the EPC Nodes dedication based on operator's configuration and policy. Additionally, the invention allows for DCN access restriction control by broadcasting of the supported DCN Types by the RAN Node.
