Abstract
Abstract A method and system are disclosed for controlling radio communications between a terminal (MS, TE) and a communications system (CN, GRAN). A communications connection between the system and the terminal is established by an active radio network controller (RNC) and an active base station (BS). In one embodiment, data communications within the communications connection is directed to the active radio controller by a second radio network controller.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A method for controlling radio communication between a terminal (MS, TE) and a communications system (CN, GRAN) in a communications system, the communication being with a spread code signal, the method comprising steps of establishing a communications connection between the system and the terminal via an active radio network controller (RNC) and active base station (BS), directing the communications connection to said active radio network controller via a second radio network controller ( 621 - 628 ), and employing in the communications system macrodiversity combining so that a spread code signal combination is carried out in a chain formed by radio network controllers serving as transmission links; wherein prior to a handover between radio network controllers, an external candidate set is established and a candidate set of a new active radio network controller is established on the basis of said external candidate set; and wherein a handover between radio network controllers comprises a preparation phase and execution phase.
Claim 2
Independent Claim
158 words
A method for controlling radio communication between a terminal (MS, TE) and a communications system (CN, GRAN) in a communications system, the communication being with a spread code signal, the method comprising steps of establishing a communications connection between the system and the terminal via an active radio network controller (RNC) and active base station (BS), directing the communications connection to said active radio network controller via a second radio network controller ( 621 - 628 ), and employing in the communications system macrodiversity combining so that a spread code signal combination is carried out in a chain formed by radio network controllers serving as transmission links; wherein prior to a handover between radio network controllers, an external candidate set is established and a candidate set of a new active radio network controller is established on the basis of said external candidate set; and wherein a handover between radio network controllers comprises a preparation phase and execution phase.
Claim 3
Dependent Claim
22 words
The method of claim 1 , wherein said preparation phase includes a step for adding a base station to the active set.
Claim 4
Dependent Claim
25 words
The method of claim 1 , wherein said execution phase includes steps for changing the active radio network controller and the active base station set.
Claim 5
Dependent Claim
26 words
The method of claim 1 , wherein said execution phase includes steps for keeping at least two radio network controllers and their base station sets active.
Claim 6
Dependent Claim
19 words
The method of claim 1 , wherein the active radio network controller and base station set are completely transferred.
