<p>Existing control plane protocol procedure(s) are employed to provide a SRNS relocation procedure to relocate a SRNS function from a source radio network controller (261) to a target radio network controller (262), even though a direct transport bearer (100) had previously been used between the source radio network controller and the Node-B. In example implementations, the existing control plane protocol procedure includes at least one of a NBAP procedure and a RNSAP procedure. In one mode of the invention, performance of the SRNS relocation procedure comprises a relocation request communicating step; a new transport bearer establishing step; a relocation triggering step; and a bearer switching step. In the relocation request communication step, the target radio network controller is notified that a relocation of the SRNS function is requested. In the new transport bearer establishing step, a new transport bearer between the target radio network controller and the Node-B. In the relocation triggering step, a relocation execution trigger message is sent from the source radio network controller to the target radio network controller. In the bearer switching step, a switch occurs from the direct transport bearer to the new transport bearer.</p> |
