Transmitting data in a wireless communications network

A radio network providing a controlling radio network controller function, wherein a radio network controller acting as a controlling radio network controller is prohibited from causing reconfiguration of a communication parameter between user equipment and said controlling radio network controller.

A method of communication in a system comprising a plurality of radio network controllers, at least one of said radio network controllers providing a controlling radio network controller function, said method comprising the step of:

• prohibiting said at least one radio network controller from causing reconfiguration of a communication parameter between user equipment and said at least one radio network controller.

A method of changing a communication parameter comprising the steps of:

• sending a message from a drifting radio network controller to a serving radio network controller of a requirement to change a communication parameter;
• and
• sending a request from said serving radio network controller to said drifting radio network controller requesting the drifting radio network controller change said communication parameter.

A communication system comprising a drifting radio network controller and a serving radio network controller, said drifting radio network controller being configured to send a message to the serving radio network controller of a requirement to change a communication parameter, and said serving radio network controller being configured to send a request to said drifting radio network controller requesting the drifting radio network controller change said communication parameter.

A drifting radio network controller configured to send a message to a serving network controller of a requirement to change a communication parameter, and in response to a request from said serving network controller to provide timing information to control timing of the change of said communication parameter.

A serving radio network controller being configured to send a request to a drifting radio network controller requesting the drifting radio network controller change a communication parameter and to reconfigure said communication parameter in accordance with timing information received from said drifting radio network controller.

A method of changing a communication parameter comprising the steps of:

• sending a reconfiguration request for changing said communication parameter from a drifting radio network controller to a serving radio network controller;
• and
• in response to said reconfiguration request, releasing and re-establishing channels of user equipment associated with said serving radio network controller using a different communication parameter.

A communication system comprising a drifting radio network controller and a serving radio network controller, said drifting radio network controller configured to send a reconfiguration request for changing a communication parameter to said serving radio network controller, and said serving radio network controller configured, in response to said reconfiguration request, to release and re-establish channels of user equipment associated with said serving radio network controller using a different communication parameter.

A drifting radio network controller configured to send a communication parameter reconfiguration request to a serving radio network controller.

A serving radio network controller configured to receive a communication parameter reconfiguration request from a drifting radio network controller, and in response to said reconfiguration request to release and re-establish channels of user equipment associated with said serving radio network controller.

A drifting radio network controller configured to perform the step of:

• sending a message to a serving radio network controller to cause said serving radio network controller to trigger a relocation procedure for a user equipment.

A serving radio network controller configured to perform the steps of:

• receiving a message from a drifting radio network controller requesting a relocation procedure for a user equipment;
• and
• in response to said message, triggering the relocation procedure for the user equipment so that said user equipment uses a single radio network controller for communication.

A method of communication, said method comprising the steps of:

• sending a relocation request from a drifting radio network controller to a serving radio network controller;
• relocating user equipment associated with said serving radio network controller with a radio network controller previously providing a drifting radio network controller function.
