Abstract
The invention discloses a method for controlling a non-scheduled resource in a high-speed uplink packet access (HSUPA) service. The method comprises the steps of: dividing out one or more levels of rates between the maximum rate and the guaranteed rate, generating a rate list based on the maximum rate, the middle levels of rates and the guaranteed rate; selecting a rate from the rate list as an access rate; allocating non-scheduled resources according to the access rate, if the non-scheduled resources are allocated successfully, finishing; if the non-scheduled resources is failed to allocate, judging whether each rate in the rate list has been tried to be an access rate; if some rates in the rate list have not been tried to be an access rate, continuing to select these rates as an access rate; if each rate in the rate list has been tried to be an access rate, finishing. By the embodiment of the invention, non-scheduled resources are fully used under the condition that a user normally uses the non-scheduled resources, and connection rate is improved.
Description
Technical field
The present invention relates to communication technical field, more specifically, relate to the control method of the professional non-scheduling resource of a kind of High Speed Uplink Packet (HSUPA) based on TD SDMA (TD-SCDMA).
Background technology
HSUPA be 3GPP the up-to-date R6 stage release at the uplink performance technique for enhancing, its adopted base station (Node B) control fast dispatch, mix technology such as automatic repeat requests (H-ARQ), shorter Transmission Time Interval (TTI), high order modulation, performance has had largely than the R4 stage and has improved.There are two kinds of transmission mechanisms, scheduled transmission and non-scheduled transmission among the HSUPA.
A, scheduled transmission:
When adopting the scheduling mode transmission,, then at first send dispatch request information to Node B by uplink random access control channel (E-RUCCH) if user (UE) has upstream data to need transmission.After Node B receives the dispatch request of UE, need to judge whether current resource allows UE to send data.If allow, then send absolute grant to UE by descending absolute grant channel (E-AGCH), notice UE carries out transfer of data.Receive the data of UE transmission as Node B after, confirm indicating channel (E-HICH) channel feedback ACK/NACK information by mixing automatic repeat requests again, whether notice UE successfully receives the data that it is uploaded.
B, non-scheduled transmission:
When adopting non-scheduling mode to transmit, radio network controller (RNC) at first is that UE distributes enhancing uplink physical channel non-scheduling resources such as (E-PUCH), afterwards the resource of distributing is passed to UE and NodeB by RRC signaling and IUB signaling.These resources mainly comprise following content:
1), the initial subframe number of available time slot, code source, maximum available power, non-scheduled transmission business;
2), repeat transmission cycle, and lasting transmission time in each transmission cycle etc.
Because UE carries out non-scheduled transmission according to the resource information that RNC distributes, and does not need to receive the dispatch command of Node B again, so can effectively reduce signaling load and the scheduling time delay of Node B.Therefore the non-scheduled transmission of HSUPA generally is applied to for example guarantee the transmission of bit rate business (GBR) and signaling in the relatively more responsive business transmission of time delay.When the user initiated the GBR business, core net was that it specifies two kinds of speed, maximum rate and assurance speed.Maximum rate is user's operable flank speed when the transmission data; Guarantee that speed is under the situation that the not obvious user of influence uses, the minimum-rate that the transmission data need.In general, maximum rate is greater than guaranteeing speed.When the GBR service access, if network side uses the non-scheduling mode of HSUPA to come transmission information, RNC can distribute non-scheduling resource according to maximum rate, also can be according to guaranteeing the rate-allocation non-scheduling resource.Divide timing by maximum rate, can satisfy user's use well.During by assurance rate-allocation non-scheduling resource, RNC can admit more non-dispatched users.
When adopting non-scheduling resource transmission data, if RNC distributes non-scheduling resource with maximum rate, admissible non-dispatched users is less.When the residue non-scheduling resource is when dividing the resource of timing needs by maximum rate among the RNC, new user will occur can't insert, so user's call completing rate will be affected.And RNC to be to guarantee the rate-allocation non-scheduling resource, because this speed ratio is lower, the non-scheduling resource that the user gets is less, influences user's normal use.
In user's the professional duration, the non-scheduling resource of CU is changeless, and the non-scheduling resource of user's actual needs is real-time conversion.RNC can't carry out the dynamic adjustment of non-scheduling resource to it according to the actual needs of user's non-scheduling resource.Therefore, the utilance of non-scheduling resource is lower.
Summary of the invention
