Abstract
The invention proposes to introduce a method for a Radio Access Network for providing 'Local Switching' between call legs of a call. Within said method the Radio Access Network receives a call identifier for a leg of a call from a Core Network to be handled by the Radio Access Network. The Radio Access Network stores said received call identifier, compares said received call identifier with stored call identifiers for call legs of calls via said Radio Access Network. If said received call identifier matches a stored call identifier the Radio Access Networks establish local switching of call legs identified by the matching call identifier. In an alternative embodiment, the invention proposes to introduce a method for a Core Network for providing local switching for call legs of a call. Within said method the Core Network receives or generates a call identifier for a leg of a call. The Core Network stores said received call identifier and identifies a respective Radio Access Network for said leg of said call. Thereafter, the Core Network compares said call received identifier with stored call identifiers for call legs of calls via said identified Radio Access Network. If said received call identifier matches a stored call identifier enforce local switching of call legs identified by the matching call identifier. The invention furthermore provides for respective Nodes of the respective Networks employing the invention.
