Abstract
A method of handling multipath connections in a Public Land Mobile Network (PLMN). The method comprising the steps of determining within the PLMN that a path, established across the PLMN, is a backup path of a multipath connection and providing an explicit indication to one or more nodes within the PLMN that the path is a backup path using a protocol layer that is otherwise unaware of the multipath connection. The method further comprises the step of, at the or each notified node, applying a handling to the path that is differentiated from the handling of non-backup paths.
Claims24
A method of handling multipath connections in a communication system comprising a public land mobile network (PLMN), the method comprising the steps of:
- determining within the PLMN that a path, established across the PLMN, is a backup path of a multipath connection;
- providing an explicit indication to one or more nodes within the PLMN that the path is a backup path using a protocol layer that is otherwise unaware of the multipath connection;
- and,
- at the or each notified node, applying a handling to the path that is differentiated from the handling of non-backup paths.
An apparatus for use in a Public Land Mobile Network (PLMN), the apparatus comprising processor circuitry, a storage unit for storing instructions executable by the processor circuitry, and a transmitter, whereby the apparatus is operative to:
- determine within the PLMN that a path, established across the PLMN, is a backup path of a multipath connection;
- provide an explicit indication to one or more nodes within the PLMN that the path is a backup path using a protocol layer that is otherwise unaware of the multipath connection;
- and
- transmit the explicit indication to one or more network nodes.
An apparatus for use in a Public Land Mobile Network (PLMN), the apparatus comprising processor circuitry, a storage unit for storing instructions executable by the processor circuitry, and a receiver, whereby the apparatus is operative to:
- receive an explicit indication that a path established across the PLMN is a backup path of a multipath connection, the indication being located in a protocol layer that is otherwise unaware of the multipath connection;
- and,
- in response to the indication, apply a handling to the path that is differentiated from the handling of non-backup paths.
