Network call park service

Abstract

A service and apparatus for enabling supplementary service functions, such as call parking, to be implemented in a communication network having one or more servers. The call parking service is adapted to enable the called party to park the call anywhere within the network, including outside the local server in a multi-server network. The call parking service includes an invite request unit for invoking the call parking service. A call park request unit is provided to respond to the invite request unit by establishing a connection to a call park destination for enabling the caller to be parked at the call park destination. A retrieval request unit is provided for connecting a call pickup party with the parked caller for completing the connection. An exception handler may also be provided to ensure that network problems in the call parking procedure do not result in a lost call.
