Embodiment 1

[0031] The Active Set Update message in this embodiment is described by taking the Active Set Update message as an example.

[0032] The Active Set Update message is used to add, delete or replace the active set link.

[0033] According to the purpose of the Active Set Update message, the modification to the existing Active Set Update message includes: adding or deleting a link in the Active Set Update message needs to indicate whether to add or delete a primary carrier frequency link or a secondary carrier frequency link. If the auxiliary carrier frequency link is added, the Active Set Update message also needs to include the configuration information of the auxiliary carrier frequency service link, including: auxiliary carrier frequency information, auxiliary carrier frequency serving cell scrambling code information, auxiliary carrier frequency HS- PDSCH configuration information, etc.

[0034] The modification of the existing Active Set Update message by the embodiment of...

Embodiment 2

[0108] The physical reconfiguration message in this embodiment is described by taking the Physical Channel Reconfiguration message as an example.

[0109] The Physical Channel Reconfiguration message is used to:

[0110] The auxiliary carrier frequency link is added, and the corresponding message includes the configuration information of the auxiliary carrier frequency link, such as: auxiliary carrier frequency information, auxiliary carrier frequency serving cell scrambling code information, auxiliary carrier frequency HS-PDSCH configuration information, etc.

[0111] To delete the secondary carrier frequency link, the corresponding message needs to indicate the frequency point, scrambling code and other information of the cell to be deleted.

[0112] The main and auxiliary carrier frequencies are swapped, and the corresponding message needs to include the configuration information of the new main carrier frequency service link and the auxiliary carrier frequency service link...

Embodiment 3

[0194] With reference to the first method embodiment, the Active Set Update message in this embodiment is described by taking the Active Set Update message as an example.

[0195] The RNC includes a first sending unit and a second receiving unit. The first sending unit sends a multi-carrier air interface reconfiguration message to the UE, and the receiving unit of the UE receives the multi-carrier air interface reconfiguration message sent by the RNC. The air interface reconfiguration unit receives the message according to the receiving unit. The multi-carrier air interface reconfiguration message is used to perform multi-carrier air interface reconfiguration, including radio bearer, transmission channel and physical channel reconfiguration. After the air interface reconfiguration is completed, the return unit returns a multi-carrier air interface reconfiguration complete message to the RNC. The second receiving unit of the RNC receives the message that the multi-carrier air i...

Abstract

Embodiments of the invention provide a multicarrier air interface reconfiguration method, user equipment and a wireless network controller. The method comprises the following steps that the user equipment UE receives an activation set update message sent by the wireless network controller RNC, wherein the activation set update message includes auxiliary carrier frequency service cell frequency information, auxiliary carrier frequency service cell scrambling code information and auxiliary carrier frequency service cell main common pilot channel information; and the UE carries out multicarrier air interface reconfiguration according to the activation set update message.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-carrier air interface reconfiguration method, user equipment and a radio network controller. Background technique [0002] High Speed ​​Downlink Packages Access (HSDPA, High Speed ​​Downlink Packages Access) technology is the most important technology to improve the high-speed downlink data transmission rate of Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) network, which can greatly improve user downlink data services rate. [0003] Usually, HSDPA is carried on a single carrier frequency. When the user equipment needs to switch to a different cell, the RNC sends an air interface reconfiguration message (for example: Active Set Update, Physical Channel Reconfiguration, Transport Channel Reconfiguration , Radio BearerReconfiguration, etc.) notify the user equipment to perform air interface reconfiguration, and after t...
