Problems solved by technology

Moreover, in the process of reconfiguration, there will be temporary packet loss of radio bearers that do not require modification.
Existing systems generally rarely use an asynchronous reconfiguration process

Embodiment Construction

[0032] The present invention is described in detail below in conjunction with accompanying drawing and embodiment, wherein, the implication of N1 Frame, T1, T2 and T3 is:

[0033] N1 Frame: The number of wireless frames until the configuration change is completed after the terminal receives the wireless interface reconfiguration message specified in the protocol 25.331 13.5.2. 1 frame is 10 milliseconds. Its size is related to the corresponding reconfiguration process.

[0034] T1: the transmission and retransmission time of the reconfiguration message itself on the original wireless link.

[0035] T2: the time that the base station controller waits for the terminal to process the reconfiguration message.

[0036] T3: time saved in the radio interface reconfiguration process after adopting the present invention.

[0037] The present invention is applicable to the reconfiguration process of the dedicated wireless link in the CS domain and the PS domain, including a radio bea...

Abstract

The invention relates to a special wireless chain redistribute method with refreshable activate time, used in wideband code-division complex system, wherein said method comprises that: BSC and base station process redistribution of synchronous wireless chain at Iub interface; BSC and terminal process redistribution of wireless interface; BSC and RRC layer confirms the successful transmission of redistribution message, wait T2 time, and convert to new distribution, send trigger message to the base station; base station receives trigger message, converts to new distribution, and sends descending DPCCH signal to terminal via new physical channel; when the terminal redistributes successfully, physical layer receives DPCCH signal at new channel, synchronizes descending data and informs the RRC layer, terminal converts to new wireless chain and sends wireless interface redistribution complete message to BSC. The inventive method can shorten time delay and reduce loss.

Description

technical field [0001] The present invention relates to Wideband Code Division Multiple Access (WCDMA), and more particularly to reconfiguration of dedicated radio links. Background technique [0002] In the existing WCDMA system, if there is already a dedicated connection between the terminal and the network, and the UE (terminal) is in the RRC (Radio Resource Control) state of CELL_DCH, if it is necessary to change the configuration of the existing wireless parameters, including radio bearer configuration, transmission channel Configuration or physical channel configuration, etc., will adopt two basic reconfiguration processes, that is, synchronous reconfiguration process and asynchronous reconfiguration process. The characteristic of the synchronous reconfiguration process is that the network and the terminal negotiate an activation time at the beginning of the reconfiguration, which is represented by CFN. At the time of the CFN, the network and the terminal switch to the...
