Abstract
A system has a first entity and a second entity. The first entity and second entity are arranged to have a control interface therebetween. At least one of said first and second entities is arranged to associate a resource with at least one connection. At least one of said first and second entities has means for checking the status of the connection and to release an associated resource if the connection is terminated.
Claims39
A system for controlling a network connection between two entities, comprising:
- a first entity;
- a second entity, said first entity and second entity being configured to have a control interface there between, at least one of said first entity or said second entity being configured to associate a resource with a connection, both of said first entity and said second entity having a checker configured to check the status of said connection wherein said checker of one of said first entity or second entity is configured to send a message to the other of said first entity or second entity requesting status information and to release the associated resource when said connection is terminated;
- wherein said checker in said other of said first entity or second entity is configured to cause termination of said connection when a status information request message is not received within a predetermined time, by sending a further message to said one of said first entity or second entity and in response to said further message said one of said first entity or second entity terminates said connection.
The system as claimed in 1, wherein said other of said first entity or said second entity is configured to send a response message to said request.
An apparatus for controlling an associated network connection, comprising:
- a control interface configured to interface with a further entity;
- an associator configured to associate a resource with said connection;
- a sender configured to transmit a status information request message to said further entity;
- a checker configured to check the status of said connection, wherein said checker is configured to receive a termination message from said further entity;
- and
- a releaser configured to release an associated resource when said connection is terminated;
- wherein said termination message is configured to cause termination of said connection, said termination message sent by said further entity when said status information request message is not received by said further entity within a predetermined time.

An apparatus for controlling an associated network connection, comprising:
- a control interface configured to interface with a further entity;
- an associator configured to associate a resource with said connection;
- a checker configured to check the status of said connection;
- and
- a sender configured to send a termination message to said further entity to indicate said further entity to terminate said connection;
- wherein said checker is configured to initiate termination of said connection when an anticipated status information request message is not received from said further entity within a predetermined time, wherein to initiate termination of said connection said sender is configured to send said termination message to said further entity, and wherein said further entity is configured to terminate said connection in response to said termination message.
3 more elements
A method for controlling a network connection between two entities, comprising:
- associating a resource with said connection in a system comprising a first entity and a second entity with a control interface therebetween;
- checking the status of the connection at at least one of said first entity or said second entity;
- and
- releasing said associated resource when said connection is terminated;
- wherein said checking comprises:
- checking if an anticipated status information request message is received by said at least one of said first entity and second entity within a predetermined time and sending, in dependence of not receiving said status information request message within said predetermined time, a termination message from said at least one of said first entity and second entity to other of said first entity and second entity wherein the other of said first entity and second entity terminates said connection in response to said termination message.
3 more elements
An apparatus for controlling an associated network connection, comprising:
- control interface means for interfacing with a further entity connected to the connection;
- association means for associating a resource with said connection;
- checker means for checking the status of said connection by sending a status information request message to said further entity, wherein said checker means is configured for receiving a message from said further entity;
- and
- releaser means for releasing the associated resource when said connection is terminated wherein said message is configured for causing termination of said connection, said message sent by said further entity when said status information request message is not received by said further entity within a predetermined time.
2 more elements
An apparatus for controlling an associated network connection, comprising:
- control interface means for interfacing with a further entity connected to said connection;
- association means for associating a resource with a connection;
- checker means for checking the status of said connection;
- and
- sender means for sending a termination message to said further entity to indicate said further entity to terminate said connection;
- wherein said checker means is configured for initiating termination of said connection when an anticipated status information request message is not received from said further entity within a predetermined time, wherein to initiate termination of said connection said sender means sends said termination message to said further entity, wherein said further entity is configured to terminate said connection in response to said termination message.
