US 6,687,249 B1 · Reconfiguring diversity legs during CN-RNC interface streamlining

Abstract

In a mobile communications network that employs diversity combining/splitting, CN-RNC interface streamlining can be accomplished more efficiently by reconfiguring the network diversity legs, which are combined into a single data stream by the serving radio network controller, wherein the serving radio network controller is directly connected to the core network via the CN-RNC interface. Reconfiguration of the network diversity legs is accomplished by releasing the transport level connections which support the network diversity legs prior to CN-RNC interface streamlining, and establishing new transport level connections to support the reconfigured, network diversity legs subsequent to CN-RNC interface streamlining. To establish new transport level connections, the serving radio network controller dispatches binding information to each of the destination nodes associated with the network diversity legs. The destination nodes then utilize the binding information to bind network resources to the transport level connections which support the reconfigured network diversity legs between the destination nodes and the serving radio network controller.

Dependent claims

In a radio access network that employs diversity combining, a method for reconfiguring diversity legs during CN-RNC interface streamlining comprising the steps of:

transferring destination address and binding information from a first radio network controller to a second radio network controller;
releasing a number of transport level connections, wherein each of the transport level connections were utilized to support a corresponding diversity leg;
establishing a new transport level connection between the second radio network controller and each of a plurality of destination nodes by dispatching a destination address and binding information from the second radio network controller to each of the destination nodes;
and
binding one or more resources at each destination node, based on the binding information dispatched to each destination node, to support a corresponding diversity leg between each destination node and the second radio network controller.

In a radio access network that employs diversity combining, a method for reconfiguring diversity legs during CN-RNC interface streamlining, wherein each diversity leg is supported by a corresponding asynchronous transfer method (ATM) adaptation layer type 2 (AAL2) transport level connection, said method comprising the steps of:

transferring destination address and binding information from an old serving radio network controller to a new serving radio network controller;
releasing a number of AAL2 transport level connections, wherein each of the released AAL2 transport level connections were used to support a diversity leg between a destination node and a diversity handover unit in the old serving radio network controller;
transporting an AAL2 set-up message from the new serving radio network controller to each of a number of destination nodes, in accordance with an existing address associated with each of the destination nodes, wherein each AAL2 set-up message contains binding information pertaining to a corresponding destination node;
and
at each destination node, binding the corresponding AAL2 connection to one or more resources, based on the binding information corresponding to the destination node, wherein the one or more resources are used to support a corresponding diversity leg between the destination node and the new serving radio network controller.
