Description

Inceptive service authorization value is determined method, system and equipment

Technical field

The present invention relates to mobile communication technology, (SG, ServingGrant) value is determined method, system and equipment in particularly a kind of initial service mandate.

Background technology

High speed uplink bag data insert (HSUPA, High Speed Uplink Packet Data Access) be 3rd Generation Partnership Project (3GPP, Third Generation Partnership Project) a kind of new technology that improves higher uplink bit rate of in version 6 agreements, introducing, adopt the up fast dispatch of base station (NodeB), physical layer is mixed re-transmission (HARQ, Hybrid Automatic Repeat request), soft handover and 2ms Transmission Time Interval (TTI, Transmission Time Interval) lack the frame transmission technology, the peak-peak speed that can support in theory is 5.76Mbps.

Fig. 1 is the structural representation of HSUPA agreement in existing Wideband Code Division Multiple Access (WCDMA) (WCDMA, the Wideband Code Division MultipleAccess) system.As shown in Figure 1, at user terminal (UE, User Equipment) side, increased medium access control (MAC, Media Access Control) layer entity MAC-es or MAC-e, be used to realize functions such as HARQ retransmits and MAC-d protocol Data Unit (PDU, Protocol Data Unit) is multiplexing.Network side has increased MAC layer entity MAC-es and MAC-e.In order to support the fast dispatch of base station, the MAC-e entity of network side has been moved down in the base station; In order to support the grand diversity of HSUPA, allow MAC-es be positioned in the service wireless network controller (SRNC, Server Radio Network Controller).Increase the dedicated channel (E-DCH, Enhanced-Dedicated Channel) that strengthens between MAC layer and the physical layer (PHY, Physical Layer), be used to carry transmission data block.

Wherein, several physical channels have been increased in the physical layer, such as, increased the Dedicated Physical Control Channel (E-DPCCH that strengthens in the uplink physical channel, E-DCH Dedicated Physical Control Channel) and the Dedicated Physical Data Channel (E-DPDCH, E-DCH Dedicated Physical DataChannel) that strengthens.Correspondingly, increased the absolute grant channel (E-AGCH that strengthens in the down physical channel, E-DCH Absolute Grant Channel), the relative authorization channel (E-RGCH of Zeng Qianging, E-DCHRelative Grant Channel) and the affirmation indicating channel (E-HICH, E-DCH HARQAcknowledgement Indicator Channel) that strengthens.Wherein, up E-DPDCH is used for carrying the upstream data of HSUPA technology UE transmission; Up E-DPCCH is used to carry the signaling of following of demodulating data channel E-DPDCH.Descending E-AGCH is a common signal channel, is used to indicate maximum available uplink speed of UE or power; Descending E-RGCH is a dedicated channel, the fastest can be by the uplink speed of the each frequency rapid adjustment UE of 2ms; Whether correct descending E-HICH is a dedicated channel, be used to send feedback user receiving process data affirmation/non-affirmation (ACK/NACK, Acknowledgement/NegativeAcknowledgement) information.

When UE is linked in the base station, the base station can dispose initial service mandate (SG for UE, ServingGrant), and by radio network controller (RNC, Radio Network Controller) by the 3rd layer of (L3, Layer 3) the authorization of service value (Serving Grant Value) of carrying in the signaling is notified to UE, and the value of initial SG value has directly determined E-DPDCH that UE can use and the power ratio of DPCCH when the transmission data.Subsequently, when UE need carry out the business transmission, can be according to the initial SG value transmission data of carrying among the Serving Grant Value.In professional transmission course, UE can be according to the value of absolute grant that is received from E-AGCH or E-RGCH channel (AG, Absolute Grant) or relative authorization (RG, Relative Grant) information updating SG.Usually, the value of SG comprises 0～37 totally 38 ranks by size.When the SG value of UE need be raised one-level or downward modulation one-level in the base station, can upgrade the SG of UE side by RG UP or RG DOWN authorization message; Raise or reduce multistage if desired, then can directly upgrade the SG of UE side by AG information.

In actual applications, ping latency is the important indicator that operator investigates network performance, and it can reflect directly whether network can in time respond the UE request.Generally, under the impregnable prerequisite of other performance, time delay is the smaller the better.

When adopting the HSUPA technology to carry out transfer of data, the initial SG value of UE will directly determine the speed that can use when UE begins to carry out transfer of data, if this value is provided with lessly, even current network resources is very sufficient so, this UE also will wait the base station to distribute AG for it or carry out could obtaining higher transmission rate after RG UP authorizes.Before this, can only carry out transfer of data, thereby cause its data in time not transmitted, promptly cause delay performance to be a greater impact with lower speed.Therefore, at this problem, must find a kind of method that can improve the UE access delay.

In the prior art, at the UE access network, carry out Radio Link set up/increase/reshuffle in the processes such as (PLSetup/Addition/Reconfigure), the base station can be in relevant response message inform that by cell " Serving Grant Value " radio network controller is the initial SG value that UE distributes; Then, radio network controller is given UE by the L3 signaling.Table one is depicted as the Serving GrantValue cell of stipulating in the agreement and forms structure.

Cell title (IE/Group Name)	Present (Presence)	Scope (Range)	Cell type (IE Type and Reference)	Describe (Semantics Description)
					Serving Grant Value	O (optional)		INTEGER (0..37，38)	(0..37)indicates E-DCH serving grant index as defined in[32]；index 38 means zero grant

Table one Serving Grant Value cell is formed structure

Wherein, the possible value of 0～37 expression SG, 38 is particular value, irrelevant with the present invention, is not described.

In the prior art, the set-up mode of initial SG value comprises two kinds, be about to that the initial SG value is set to 0 mode and according to guaranteeing bit rate (GBR, MAC-es Guaranteed Bit Rate) mode of initial SG value is set, promptly, by the GBR value of radio network controller informing base station UE correspondence, the initial SG value of UE is determined in the base station according to this GBR value.The characteristics of this dual mode itself have determined fundamentally to solve UE access delay problem, because:

If the initial SG value is set to 0, so, has only periodically reporting scheduling information (SI of the follow-up UE of working as, Schedule Information), be informing base station self when having how many data to send, the base station just can be authorized for UE distributes AG, so that UE begins to carry out transfer of data.If the initial SG value is provided with according to GBR, though be set to 0 situation with respect to the initial SG value, can reduce time delay to a certain extent, but GBR only need distribute to the minimum transmission rate of UE for the base station, generally, the value of the initial SG value of determining in this manner is very little, when needs increase the value of SG, also needs to authorize by follow-up AG or RG and carries out raising speed.

As seen, the initial SG value of SG method to set up of the prior art is provided with lessly, and the access delay of UE when network side transmission data is also bigger.
