Relate to the communications field, particularly relate to a kind of transmission intercal TTI type changing method, equipment and system.

Background technology

Along with the develop rapidly of the communication technology, WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) as one of the mainstream technology of 3-G (Generation Three mobile communication system), obtain investigation and application widely in the world.At 3GPP (3rd Generation Partnership Project, third generation Partnership Program) introduce DCH (Dedicated Channel in the Rel-99 version formulated, dedicated channel), be called R99 DCH, the covering that R99 DCH channel has had, but lower data rate can only be improved.The Rel-6 version formulated at 3GPP introduces HSUPA (High-Speed Uplink Packet Access, High Speed Uplink Packet accesses) technology, the transmission channel introduced in HSUPA technology is E-DCH (Enhanced Dedicated Channel, up enhancing).This E-DCH channel comprises two kinds of TTI (Transmission Time Interval, transmission intercal) type, be respectively 2ms TTI type and 10ms TTI type, wherein, 2ms TTI type can provide high message transmission rate and little propagation delay time, and 10ms TTI type can provide better covering.Therefore, as UE (User Equipment, subscriber equipment) when moving to cell edge from center of housing estate, just need to be switched to 10ms TTI type from 2ms TTI type to obtain better to cover, accordingly, when UE moves to center of housing estate from cell edge, just need to be switched to 2ms TTI type from 10ms TTI type to obtain higher peak rate.It should be noted that, R99 DCH TTI type has 10ms TTI type, 20ms TTI type, 40ms TTI type and 80ms TTI type, the covering of usual R99 DCH is greater than E-DCH and covers, so when UE moves to cell edge, even if UE is current use E-DCH 10ms TTI type, likely cover and still have problems, need to be switched to 2ms TTI type from E-DCH 10ms; Or when UE moves to cell edge, need UE to be switched to DCH from E-DCH 2ms TTI type.

In the prior art, normally by covering measurement procedure, (namely UE is by SI reporting (Scheduling Information, schedule information) by UPH (UE transmission power headroom, UE transmitting power surplus) report base station, base station reports radio network controller (Radio Network controller again, radio network controller), radio network controller is made to determine whether that performing TTI switches according to UPH, or the switching whether performed between R99 DCH and E-DCH) and switch execution flow process two aspects to carry out TTI handoff procedure.

But in the TTI type switching procedure stated in realization, inventor finds when the data volume of buffer memory in UE is 0, i.e. TEBS (Total E-DCH Buffer Status, total enhancing dedicated channel buffer status) when being zero, also can not SI reporting even if SI meets report condition UE, make UPH sample size inadequate, or, when upstream data rate is too high, even if UE can be caused UPH also to be caused very little in heart position in the cell, thus cause radio network controller can accurately not perform TTI handoff procedure based on URH.
