Description

Uplink dispatch method and system, terminal and base station
Technical field
The present invention relates to a kind of uplink random access technology, relate in particular to uplink dispatch method and system, terminal and base station in a kind of High Speed Uplink Packet connecting system.
Background technology
High-speed uplink packet access technology retransmits the performance that means such as merging are improved system for uplink packet data fast through fast dispatch and physical layer.For this reason; High-speed uplink packet access technology has been introduced a kind of new transmission channel-enhanced dedicated (E-DCH; Enhanced Dedicated Transport Channel) be used for carrying user data, E-DCH is specifically designed to the up channel that carries upstream data.In addition, the physical channel of bearing reinforced dedicated transmission channel is Physical Random Access Channel (PRACH, Physical Random Access Channel).
There are two basic manipulation modes at the terminal, is respectively idle pulley and connection mode.Connection mode can further be divided into following different state: Universal Mobile Telecommunications System wireless access network registration area PCH (URA_PCH; Universal mobile telecommunication system Radio access network Register area Paging Channel) state, cell paging channel (CELL_PCH; CELL Paging Channel) state, cell forward access channel (CELL_FACH; CELL Forward Access Channel) state and cell private channel (CELL_DCH; CELL Dedicated Channel) state etc., these states have defined the kind of operable physical channel in terminal and transmission channel.
Under the CELL_FACH state, high-speed uplink packet access technology can be used in the terminal when sending upstream data, send uplink user data through enhanced dedicated.The Transmission Time Interval of enhanced dedicated has two kinds; A kind of is 2 milliseconds Transmission Time Interval; The enhanced dedicated data are sent in the scheduling of just carrying out enhanced dedicated with 2 milliseconds gap periods, and this 2 milliseconds Transmission Time Interval is called the short transmission time interval; A kind of in addition is 10 milliseconds Transmission Time Interval, and the enhanced dedicated data are sent in the scheduling of just carrying out enhanced dedicated with 10 milliseconds gap periods, and this 10 milliseconds Transmission Time Interval is called the longer transmission time interval.
The propelling movement (PUSH Email) like Email, virtual connection etc. are carried out when professional in the terminal, need and server between transmission/reception parcel data continually.Be directed to this, the terminal can adopt resident CELL_FACH state to realize above-mentioned business, to avoid arriving continually the state transition of CELL_DCH.In addition; Intelligent mobile phone terminal is at UMTS (UMTS; Universal Mobile Telecommunications System) obtained extensive use in; Need to be directed against the service efficiency that the existing network present situation puts forth effort to promote up link, particularly need promote the service efficiency of enhanced dedicated.
In the prior art, all public enhanced dedicated resources are merely able to be configured to the short transmission time interval, perhaps are merely able to be configured to the longer transmission time interval.Consider that this that need guarantee bigger RACH coverage mainly retrains, the dispatching cycle in the longer transmission time interval is selected to be configured in the common taxis of network ground.Like this, transmit data with regard to making those terminals that possess more high-power surplus be forced to use than low rate, the gain that makes the fast dispatch in the short transmission time interval bring is unavailable.Simultaneously, those possess the terminal of smaller power surplus, are benefited the bigger cell edge coverage that also can't bring from the dispatching cycle in the longer transmission time interval.
Consider above-mentioned restriction, expectation improves as follows, and the public enhanced dedicated resource in the sub-district both can be used for the scheduling in the short transmission time interval, also can be used for the scheduling in the longer transmission time interval.To network coverage situation and termination property, use the enhanced dedicated resource by the terminal Dynamic Selection short transmission time interval or the longer transmission time interval, not only to guarantee coverage but also can satisfy user's high rate data transmission demand.
