Mobile communications system and operation control method, and node and wireless control apparatus therefor

A node connected to a wireless control apparatus connected to a mobile communications unit and provided on a packet switching (PS) network side configuring a core network of a mobile communications system, wherein the node is arranged for packet processing, for packet switching communication with said PS network side, of circuit switching (CS) calls of the mobile communications unit and PS calls of the mobile communications unit, comprising:

• PS user data processing unit configured to control user data relating to a PS call of the mobile communications unit;
• CS user data processing unit configured to control user data relating to a CS call of the mobile communications unit;
• and
• control unit configured to control said PS and CS user data processing units by controlling signaling relating to the PS call and the CS call.

A wireless control apparatus connected to a mobile communications unit and a node which is provided between the wireless control apparatus and an IP network and on a packet switching (PS) network side forming a core network, wherein the node is arranged for packet processing, for packet switching communication with said PS network side, of circuit switching (CS) calls of the mobile communications unit and PS calls of the mobile communications unit and comprises:

• PS user data processing unit configured to control user data relating to a PS call of the mobile communications unit;
• CS user data processing unit configured to control user data relating to a CS call of the mobile communications unit;
• and
• control unit configured to control said PS and CS user data processing unit by controlling signaling relating to the PS call and the CS call, wherein:
• a connection request relating to the CS call from the mobile communications unit includes information about a connection through the IP network;
• and
• a detector unit configured to detect the information and, in response, to connect the CS call to the node.

An operation control method for a mobile communications system having a wireless control apparatus connected to a mobile communications unit, comprising:

• providing a node on a packet switching (PS) network side configuring a core network, the node configured for packet processing, for packet switching communication with said PS network side, of user data of a PS call of the mobile communications unit and for packet processing of user data of a circuit switching (CS) call of the mobile communications unit
• performing, within the node, a PS user data processing controlling user data relating to a PS call of the mobile communications unit;
• performing, within the node, a CS user data processing controlling user data relating to a CS call of the mobile communications unit;
• and
• performing, within the node, a control controlling signaling relating to the PS call and the CS call.

A tangible record medium encoded with a program that can be executed by a computer which is used to direct a computer to perform an operation of a node which is connected to a wireless control apparatus connected to mobile communications unit and provided on a packet switching (PS) network side configuring a core network of a mobile communications system, wherein the node is arranged for packet processing, for packet switching communication with said PS network side, of circuit switching (CS) calls of the mobile communication unit and PS calls from the mobile communication unit, the operation comprising:

• a PS user data processing controlling user data relating to a PS call of the mobile communications unit;
• a CS user data processing of controlling user data relating to a CS call of the mobile communications unit;
• and
• a control controlling signaling relating to the PS call and the CS call.
