Description
Technical field
The present invention relates to the communications field, in particular to a kind of collocation method and device of transmission bearer of uplink common control channel.
Background technology
Along with the evolution of mobile communication system, the QoS of user has become the primary goal of operator, and QoS have impact on service performance, also determines the satisfaction of user to business.The very important aspect improving QoS of customer is exactly connect and time delay during channel allocation, and can there is related frequency, the business of small data packets, therefore needs to consider how common signal channel works more effective.Such as reduce the signaling delay of up link and down link.The downlink signaling of CELL_FACH, CELL_PCH/URA_PCH state postpones 3GPP standard and realizes by introducing down high speed grouping access (HSPA).
In order to reduce up signaling delay, need to consider following several aspect:
(1) IDLE mode is reduced, the user face of CELL_FACH, Cell_PCH and URA_PCH state and the stand-by period of chain of command;
(2) peak rate of CELL_FACH state is increased;
(3) transition delay between Idle, CELL_FACH, CELL_PCH and URA_PCH state, CELL_DCH state is reduced.
In order to achieve the above object, can introduce in Idle pattern, CELL_FACH state the mode using high speed uplink packet access (HSUPA); Idle state and CELL_FACH state are used high-speed uplink packet access technique herein, be called uplink reinforced CELL-FACH technology.
The general principle of uplink reinforced CELL-FACH technology is as follows: the transmission principle of Stochastic accessing still adopts the random access procedure of PRACH, but channel type there occurs change, also namely can use in idle pattern and CELL_FACH state and strengthen dedicated channel (Enhanced Dedicated Channel, referred to as E-DCH), Common Control Channel (Common Control Channel, referred to as CCCH)/Dedicated Control Channel (Dedicated Control Channel, referred to as DCCH)/Dedicated Traffic Channel (Dedicated Traffic Channel, referred to as DTCH) can be mapped on E-DCH and send.
Transmission bearer is the necessary passage as carrying out transfer of data between radio network controller and base station, therefore for the channel of common condition, all need by public process between radio network controller and base station for transmission channel or media access control flow set up the passage of transmission bearer, then radio network controller can identify by transmission bearer that to distinguish be the data come from which transmission channel or which media incoming stream.
At present, 3GPP standard agreement is associated for the transmission bearer mark used under reinforcement connection mode common condition and media access control flow, and be identify according to up public MAC stream for the configuration of transmission bearer in 3GPP standard agreement, the relevant information that corresponding up open E-DCH MAC-d flows under this mark simultaneously.But for up the sent Common Control Channel (CommonControl Channel, referred to as CCCH) strengthened under connection mode common condition, agreement does not provide the media access control flow of its correspondence.And from public flow process, be not also up CCCH configuring transmission carrier specially, also do not clearly state after coming up for the data transmission on up CCCH logic channel, how Node B determines to use which transmission bearer to be delivered to RNC.
For up CCCH logic channel, its priority should be very high, and therefore, the QoS of the transmission bearer required for up CCCH logic channel to flow from common MAC-d for the requirement of transmission bearer QoS is different.If Node B use common E-DCH MAC-d when transmitting the data of up CCCH logic channel flows any one in the transmission bearer used, then the QoS of up CCCH cannot be met, thus the data affected on up CCCH are correctly delivered to the probability of success of radio network controller (Radio Network Control: referred to as RNC).
For the problem that in correlation technique cannot be correctly up CCCH configuring transmission carrier, at present effective solution is not yet proposed.
