Abstract

The invention relates to a special physical data control channel time slot format sending method, which comprises the following steps: radio network controller notifies, by signaling, node B of the special physical data control channel time slot format used by the user equipment in uplink strengthened cell forward accessing channel state; the node B acquires the special physical data control channel time slot format information from the signaling and saves. By applying the invention, when the user equipment is in uplink strengthened CELL_FACH state, the node B can acquire the DPCCH time slot format information used by the user equipment, and decodes the DPCCH according to the information.

Description

A kind of sending method of time slot format of special physical data control channel

Technical field

The present invention relates to mobile communication system, relate in particular to a kind of sending method of time slot format of special physical data control channel.

Background technology

Along with the evolution of mobile communication system, the QoS that improves the user has become the primary goal of operator.QoS has influenced service performance, has also determined the satisfaction of user to business.A very important aspect that improves QoS be exactly when reducing to connect with channel allocation time delay and to take place relative frequently but the processing mode of the less business of data volume, therefore needing the consideration common signal channel how to work could be more effective, as considering how to reduce the signaling delay of up link and down link.At present, the 3GPP standard reduces CELL_DCH (Cell Dedicated Channel by introducing HSDPA (high-speed downlink packet access), cell private channel), CELL_FACH (CellForward Access Channel, cell forward access channel), CELL_PCH (Cell PagingChannel, the cell paging channel), URA_PCH (UTRAN Registration Area PagingChannel, UTRAN registration area paging channel) downlink signaling of state postpones, and how to reduce above-mentioned various states up signaling delay issue still under discussion.

In order to reduce the delay of up signaling, need to consider the problem of following several aspects:

(1) reduces IDLE mode (idle pulley), CELL_DCH, CELL_FACH, CELL_PCH and the user's face of URA_PCH state and the stand-by period of chain of command;

(2) peak rate of increase CELL_FACH state;

(3) reduce the transition delay of CELL_FACH, CELL_PCH, URA_PCH and CELL_DCH state.

In order to achieve the above object, can introduce the mode of HSUPA at the CELL_FACH state.For convenient statement, will under the CELL_FACH state, use high-speed uplink packet access technology hereinafter, abbreviate CELL _ FACH state enhanced on uplink as.

For high-speed uplink packet access technology, it also must use DPCCH (special physical data control channel) when using E-DPCCH (E-DCH special physical data control channel) and E-DPDCH (E-DCH special physical data control channel) physical channel.This DPCCH is used to keep the synchronous of link, and as benchmark E-DPCCH and E-DPDCH is carried out the power adjustment.

And for CELL _ FACH state enhanced on uplink, because it can send data in a long time, though be the CELL_FACH state this moment, but be the physical channel working method of its communication and under the CELL_DCH state, use the HSUPA technology as broad as long that it also needs the DPCCH co-operation just can finish the transmission of data so.

For the Iub mouth, when subscriber equipment (UE) was in the CELL_FACH state, based on present agreement, Node B was the time slot format that can't obtain DPCCH.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of sending method of time slot format of special physical data control channel, makes that under CELL _ FACH state enhanced on uplink, Node B can correctly be decoded to DPCCH.

For addressing the above problem, the invention provides a kind of sending method of time slot format of special physical data control channel, may further comprise the steps:

Radio network controller passes through the signaling Node B under the uplink reinforced district forward access channel status, the time slot format information of the employed special physical data control channel of subscriber equipment; Described Node B obtain described time slot format of special physical data control channel information from described signaling after is preserved it.

Further, said method also can have following feature: described radio network controller increases a field in described signaling, after in described field, adding described time slot format of special physical data control channel information, described signaling is sent to described Node B.

Further, said method also can have following feature: described signaling is that the request of Physical Shared Channel reprovision, Common transport channel foundation request or Common transport channel are set up any one in the reprovision request.

Further, said method also can have following feature: described time slot format of special physical data control channel span is 1,3 or 4.

Adopt the present invention, when subscriber equipment is in CELL _ FACH state enhanced on uplink following time, Node B can get access to the employed DPCCH time slot format information of above-mentioned subscriber equipment, in view of the above DPCCH is decoded.
