Abstract
The current invention defines a device and a method of logically inserting the device between two other network devices, for example, in a 3GPP Radio Access Network. The device transparently monitors and interacts with one or more control protocol layers in the two neighboring devices. The invention defines methods by which the intercepting node selectively passes through or proxies (selectively modifying portions of the protocols content) in such as way that the neighbor nodes are un-aware of the intercepting device. The proxy operation implies that the intercepting node is capable of terminating some protocol elements, injecting some protocol elements, or modifying protocol elements before forwarding them in such a way that the operation is transparent to neighboring nodes. These selective insertion/modifications facilitate identifying signaling connections for specific mobile clients, and enhancing and modifying service features for dataplane accesses for those client devices, while transparently passing other protocol messages.
