Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] In a WCDMA system, the cell update process includes the following steps:

[0046] Step 1, UE sends a cell update (CELL UPDATE) message to a radio network controller (RNC: Radio Network Controller);

[0047] Step 2, RNC returns cell update confirmation (CELL UPDATE CONFIRM) message to UE;

[0048] Step 3: The UE will send a response message to the RNC according to the relevant information elements in the CELL UPDATE CONFIRM message.

[0049] In step 3, the response message can be one or any combination of the following messages:

[0050] ① UTRAN mobility information confirmation message (UTRAN MOBILITY INFORMATION CONFIRM);

[0051] ②Physical channel reconfiguration complete message (PHYSICAL CHANNELRECONFIGURATION COMPLETE);

[0052] ③Transport channel reconfiguration complete message (TRANSPORT CHANNELRECONFIGURATION COMPLETE);

Abstract

The invention relates to a method for refreshing region, which comprises: a, user terminal sends region refresh request; b, wireless network controller receives the request and feedbacks refresh confirmation to the user terminal; c, user terminal via the confirmation sends answer message to the controller; wireless network controller receives the answer message to manage the user terminal and complete the refresh process. In one region refresh process, the region refresh confirmation feedback from wireless network controller carries same mark.

Description

technical field [0001] The invention relates to a Wideband Code Division Multiple Access (WCDMA: Wideband Code Division Multiple Access) system, in particular to a method for realizing cell update of the WCDMA system. Background technique [0002] For a user terminal (UE) in a cell_paging channel (CELL_PCH, a state of a mobile user) or a cell_forward access channel (CELL_FACH, a state of a mobile user) in a WCDMA system ), when a radio resource control (RRC: Radio Resource Control) connection has been established and the cell location of the user terminal is known to the Universal Terrestrial Radio Access Network (UTRAN: Universal Terrestrial Radio Access Network), the cell update is to update the network side user The process of terminal cell-level location information. [0003] Referring to FIG. 1 , it is a schematic diagram of a cell update process in a prior art WCDMA system. The process of cell update in this WCDMA system includes the following steps: [0004] Step 1...
