1. A method for relocating a user equipment (UE) between radio network controllers, the method comprising:
- receiving, by a target radio network controller (RNC), a UE-not-involved RNC relocation required message, wherein the message comprises a transparent container from a source RNC to the target RNC sent by the source RNC and a coding scheme indicated by a core network (CN), wherein the transparent container includes a coding scheme configured for the UE; and
in response to determining that the coding scheme configured for the UE is inconsistent with the coding scheme indicated by the CN, sending a transparent container by the target RNC to the source RNC, wherein the transparent container comprises a reconfiguration message used to change the coding scheme of the UE, so that the source RNC sends a reconfiguration message to the UE.

Abstract
The present invention, relating to the field of communications technologies, discloses a method, an apparatus, and a system for relocating a user equipment between radio network controllers. The present invention is directed to configuring the coding scheme configured for the user equipment UE to a coding scheme consistent with the coding scheme supported by a target radio network controller to relocate the UE to the target RNC. The present invention is mainly applicable to inter-RNC handovers.

6. A radio network controller (RNC), comprising:
-
a receiver device, configured to receive a user equipment (UE)-not-involved RNC relocation required message, wherein the message comprises a transparent container from a source RNC to a target RNC sent by the source RNC and a coding scheme indicated by a core network (CN), wherein the transparent container includes a coding scheme configured for the UE; and a sender device, configured to send the source RNC a transparent container from the target RNC to the source RNC, wherein the transparent container comprises a reconfiguration message used to change the coding scheme of the UE, so that the source RNC sends a reconfiguration message to the UE. - View Dependent Claims (7, 8, 9, 10)

11. A radio network controller (RNC), comprising:
-
a sender device, configured to send a user equipment (UE)-not-involved RNC relocation required message to a core network (CN), so that the CN sends a relocation required message to a target RNC; and a receiver device, configured to receive a relocation command message sent by the CN, wherein the relocation command message comprises a transparent container from the target RNC to a source RNC sent by the target RNC, wherein the transparent container comprises a UE coding scheme reconfiguration message; wherein the sender device is further configured to send a reconfiguration message to the UE, that causes the UE to change the coding scheme according to the reconfiguration message.
