Description

Activation collection management method and radio network controller

Technical field

The present invention relates to a kind of radio honeycomb communication system, more particularly to a kind of activation collection management method and wireless network control Device processed.

Background technology

The R99 standard agreements of WCDMA (WCDMA) mobile communication system are supplied to the flank speed of user general For 384kbps, hot zones can provide the speed of 2Mbps.From the supported dedicated channels for transmitting grouped data of R99 The performance of (dedicated channel, DCH) and DSCH Downlink Shared Channel (downlink shared channel, DSCH) is come See, for the user in general area, the function of the transmission packe business that R99 standard agreements are provided has been able to meet user Demand, but the increase with Packet Service user and the demand to high speed packet service, R99 provide rate bandwidth will The demand of hot zones user can not be met；Therefore R5 standard agreements introduce high speed downlink packet access technology (HSDPA), A kind of shared transmission channel (the High Speed Downlink Shared Channel of high-speed packet are introduced：HS-DSCH), The channel adopts time-division and code division mode, and the channel employs mixed automatic retransfer (HARQ) and Adaptive Modulation and Coding (AMC) technology so that peak rate is up to 14Mbps.R6 standard agreements are also introduced into high-speed uplink packet access technique to up (HSUPA), namely introduce enhancing transmission channel (Enhanced dedicated Channel, E-DCH), the channel is equally adopted With mixed automatic retransfer (HARQ) so that peak rate can reach 5.76Mbps.With the evolution of agreement, HSDPA and HSUPA Apply higher order modulation mode, MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) technologies with And multi-carrier frequency is used in combination technology, its final purpose be by provide high speed packet service is accessed increase the capacity of system with And reduce transmission delay to improve requirement of the user to service quality (Qos).

It is after HSDPA technologies are introduced, descending no longer to need DPCH transmission data, but need up-downgoing to do internal ring Power control, therefore introduce F-DPCH (Fractional Dedicated Physical Channel, the special physics letter of burst Road), to reduce waste of the HSDPA user to code resource, improve the utilization rate of code resource.It is after introducing F-DPCH channels, then many User can share a F-DPCH (only taking up the spreading code of 256 equivalent to 10 users) using time division way, initially The time division multiplex of the F-DPCH of introducing realized by configuring chip offset, but such implementation have one it is non- Often big shortcoming：Because the multilink of soft handover needs time unifying, therefore during for increasing link, which increases link Timing relationship be fixed, radio network controller can not be adjusted, so for the clear position on allocated F-DPCH Can not distributing user, ultimately resulting in F-DPCH can not be re-used completely.Therefore 3GPP subsequently introduces enhancing F-DPCH (E- DPCH), strengthen F-DPCH and common F-DPCH difference be：Strengthen F-DPCH and define time slot format, the multiplexing of multi-user As long as mode configures different time slot formats, such F-DPCH just can all reusable in any case, the code utilization of resources Rate is improved.Specific time slot format is as shown in table 1.

Table 1 strengthens the time slot format of F-DPCH

Using strengthening after F-DPCH, user equipment is moved to from the cell for supporting enhancing F-DPCH and do not support enhancing F-DPCH Cell when, it sometimes appear that problems with：Service outage duration is elongated, the reduction of handling capacity.

The content of the invention

The technical problem to be solved in the present invention is to provide a kind of activation collection management method and radio network controller, to solve The problem that service outage duration length, handling capacity are reduced.

To solve above technical problem, the present invention provides a kind of activation collection management method, service wireless network controller (RNC) set up using commonly or after the link of enhancing fractional-dedicated physical channel (F-DPCH) with user equipment, the method includes：

Select to support general in the cell that the Serving RNC meets condition from the channel quality of the Drift Radio Network Controller administration for monitoring Target cell that is logical or strengthening F-DPCH；

The Serving RNC indicates that Drift Radio Network Controller is directed to the corresponding channel of the corresponding link establishment of each Target cell.

To solve above technical problem, present invention also offers a kind of radio network controller (RNC), the RNC includes：

Target cell select unit, sets up using the common or special thing of enhancing burst as Serving RNC and with user equipment When after the link of reason channel (F-DPCH), for meeting in the cell of condition from the channel quality of the Drift Radio Network Controller administration for monitoring Select to support Target cell that is common or strengthening F-DPCH；

Activation collection administrative unit, during as Serving RNC, for indicating that Drift Radio Network Controller is directed to the corresponding chain of each Target cell Corresponding channel is set up on road；During as Drift Radio Network Controller, for the indicator according to Serving RNC to the corresponding chain of each Target cell Corresponding channel is set up on road.

In the inventive method and radio network controller, the link under floating radio network controller administration allows F- The cell of DPCH and enhancing F-DPCH is concentrated in same activation so that user equipment has soft handover gain, it is to avoid different The cell for holding ability can not be in the generation that the caused direct-cut operation of institute is concentrated in same activation, so as to improve the service quality of business, Reduce service outage duration, improve handling capacity.

Specific embodiment

Realize below in conjunction with particular technique, when changing to the Serving cell of user equipment, it is elongated service outage duration occur, The situation analysis of the reduction of handling capacity is as follows：

Common F-DPCH and enhancing F-DPCH are the abilities of node B, can there are different supports in whole ad-hoc network The node B of ability, the Iur mouths of current 3GPP agreements are configuring according to the rank of user equipment for the use for strengthening F-DPCH , namely do not support to be configured with F-DPCH and strengthen F-DPCH to concentrate in same activation, when user equipment strengthens F- from distribution The cell of DPCH moves to the cell for not supporting to strengthen F-DPCH, because not supporting that the cell for strengthening F-DPCH can not increase to use The activation of family equipment is concentrated, then business cannot have soft handover gain, when Serving cell changes, then can only just walk direct-cut operation Process, therefore compared to soft handover by traffic affecting performance and Consumer's Experience, such as service outage duration is longer than soft cutting Change, in the Zone switched reduction that can cause handling capacity.

Analyze based on more than, this patent proposes a kind of activation collection management method, solves because caused by direct-cut operation Impact to service feature.
