Embodiment 1

[0026] Specifically, such as figure 1 As shown, Embodiment 1 of the active set management method of the present invention includes:

[0027] Step 101: The serving RNC selects a target cell supporting normal or enhanced F-DPCH from the monitored cells whose channel quality meets the conditions under the jurisdiction of the drifting RNC;

[0028] It should be noted that the normal F-DPCH channel mentioned in this document refers to the F-DPCH before the introduction of the enhanced F-DPCH.

[0029] The cell whose channel quality satisfies the condition is determined based on the measurement result reported by the user equipment.

[0030] The serving RNC needs to select the target cell from the cells whose channel quality meets the conditions according to the support capability information of the cell under the jurisdiction of the drift RNC. The support capability information can be preset information in the serving RNC, or can be obtained from the drift RNC. Specifically, the ...

Embodiment 2

[0041] In the second embodiment, the active set management method of the present invention is described from the perspective of the serving radio network controller.

[0042] Specifically, the processing steps of serving the wireless network controller include:

[0043] Step 1: The serving radio network controller and the user equipment have established a communication link, and are already using a common F-DPCH or an enhanced F-DPCH channel;

[0044] Step 2: The serving radio network controller obtains the support capability information of the F-DPCH and the enhanced F-DPCH of the cell under the jurisdiction of the drift radio network controller in advance;

[0045] Step 3: The serving radio network controller detects that the cell under the jurisdiction of the drifting radio network controller has a channel quality that meets the conditions, which may be one or more cells;

[0046] Understandably, there is no sequence limitation between the first step and the second step an...

Embodiment 3

[0052] In the second embodiment, the active set management method of the present invention is described from the perspective of the drift radio network controller.

[0053] Specifically, the drift radio network controller performs different processing according to the received instructions:

[0054] If the drift radio network controller receives an indication from the serving radio network controller that a certain link needs to use the enhanced F-DPCH, it allocates the enhanced F-DPCH channel for the radio link, and initiates the establishment of enhanced F-DPCH to the Node B under its jurisdiction. The process of the F-DPCH channel;

[0055] If the drift radio network controller receives an indication from the serving radio network controller that a certain link uses a common F-DPCH, it allocates a common F-DPCH channel for the radio link, and initiates the establishment of a common F-DPCH to the Node B under its jurisdiction. - Procedure for DPCH channel.

Abstract

The invention relates to an active set management method and a wireless network controller. Links using ordinary or strengthening fractional-dedicated physical channels (F-DPCH) are built through a service radio network controller (RNC) and a user device. The method comprises that a target community which supports an ordinary or strengthening F-DPCH in communities of which the quality of the channels meets the requirement, which are managed by a drift RNC which is detected is chosen by the service RNC; and the service RNC instructs the drift RNC to build corresponding channels according to corresponding links of target communities. According to the method and the wireless network controller, the service interruption time is reduced and the handling capacity is increased.

Description

technical field [0001] The invention relates to a wireless cellular communication system, in particular to an active set management method and a wireless network controller. Background technique [0002] The R99 standard protocol of the Wideband Code Division Multiple Access (WCDMA) mobile communication system provides users with a maximum rate of 384 kbps, and hot spots can provide a rate of 2 Mbps. From the perspective of the performance of the dedicated channel (dedicated channel, DCH) and downlink shared channel (downlink shared channel, DSCH) that R99 can support for transmitting packet data, for users in general areas, the transmission packet provided by the R99 standard protocol The function of the service can meet the needs of users, but with the increase of packet service users and the demand for high-speed packet services, the rate and bandwidth provided by R99 will not be able to meet the needs of users in hotspot areas; therefore, the R5 standard protocol introdu...
