Network directed call pickup service

摘要

A system and apparatus for enabling supplementary service functions, such as directed call pickup, to be implemented in a communications network having more than one server. The multi-server call pickup system is adapted to enable a user to pick up another user's call from a selected destination anywhere within the network, including outside the local server in a multi-server network. The directed call pickup system includes a pickup request unit that is used for initiating the call pickup feature from a specified location in the network. A remote determination unit and a local determination unit to determine whether to establish local or remote connections to a call pickup user may also be provided. A call establishing unit with a negotiation process for connection establishment is provided to establish a connection between the call and the call pickup user. A notification unit may be provided to notify the system of the completed connection. A link release unit may also be provided to release any temporary links used in establishing the connection. A restriction checking unit may be provided as well to ensure that the pickup user is appropriate for picking up the call. An exception handler to enable the appropriate handling of service errors may also be provided.
