Embodiment
The normal flow process of using of enhancing CELL_FACH technology of 3GPP R7 standard agreement definition is at present as follows:
1, support the UE that strengthens CELL_FACH first to monitor the HS-DSCH common system information IE (HS-DSCH public system message cell) carrying in System Information Block type 5and 5bis (system message block type 5 and the 5bis) message of Cell Broadcast CB, configuration strengthens the needed basic parameter of CELL-FACH, wherein must comprise Common H-RNTI, BCCH specific H-RNTI.
Wherein, IE is the abbreviation of cell (Information element), RNTI is the abbreviation of Radio Network Temporary Identifier (Radio Network Temporary Identifier), H-RNTI is the abbreviation of HS-DSCH-RNTI, and BCCH is the abbreviation of Broadcast Control Channel (Broadcast Control Channel).
2, this UE is by carrying Support of HS-PDSCH in CELL_FACH IE in RRC CONNECTION REQUEST message and Support of MAC-ehs IE informs radio network controller (Radio Network Controller, RNC) it supports to strengthen CELL_FACH (Enhanced Cell FACH, E-FACH).
Wherein, RRC is that Radio Resource is controlled the abbreviation of (Radio Resource Control).MAC is the abbreviation that media are got involved key-course (MAC Medium Access Control).
If the known current UE of 3 RNC is stationed community and is also supported to strengthen CELL_FACH, in RRC Connection Setup message, can indicate UE in CELL_FACH state, and other relevant parameters of configuration HS-DSCH reception, comprise dedicated H-RNTI.
4, UE returns to RRC Connection Setup Complete message, the HS-DSCH physical layer category of portability UE in this message, and now UE will be in monitoring HS-SCCH physical channel state.
5, when at BCCH, CCCH (Common Control Channel, Common Control Channel), DCCH (Dedicated Control Channel, Dedicated Control Channel), DTCH (Dedicated Control Channel, while Dedicated Traffic Channel) having message signaling or data to transmit, RNC by the HS-DSCH Frame by Iub interface (being the interface between RNC and Node B) (as, HS-DSCH data frame format 2, HS-DSCH DATA FRAME TYPE2) by these signalings or transfer of data to Node B, in this Frame, carry corresponding H-RNTI simultaneously.
When 6, Node B is dispatched to these data according to queue priority, need according to HS-DSCH Frame, (be called for short, FP frame) classification of entrained H-RNTI is carried out different transpost formats combination of resources (Transport Format Resource Combination, TFRC) select to process minute following two kinds of situations:
When A, Node B are dispatched to these data according to queue priority, if the entrained H-RNTI of FP frame is BCCH dedicated H-RNTI, these data are BCCH message signaling, the HS-SCCH configuring according to high level and HS-PDSCH power and fixing channel code number are carried out signaling data transmission, ignore RACH measurement result cell (RACH Measurement Result IE), now to encrypt H-RNTI used be BCCH dedicated H-RNTI to HS-SCCH.
When B, Node B are dispatched to these data according to queue priority, if the entrained H-RNTI of FP frame is not BCCH dedicated H-RNTI, these data are CCCH, DCCH, DTCH signaling or data, NodeB is with reference to HS-DSCH physical layer classification Category 12, coordinate the RACHMeasurement Result IE (being generally the Ec/N0 of CPICH) in this data place FP frame to carry out TFRC selection, and the H-RNTI getting accordingly in FP frame carry out HS-SCCH encryption.
Wherein, CPICH is the abbreviation of Common Pilot Channel (Common Pilot Channel), and Ec/N0 refers to chip-level signal to noise ratio.
If having distributed, 7 UE obtain dedicated H-RNTI, UE monitors HS-SCCH channel with the H-RNTI of dedicated H-RNTI and BCCH special use simultaneously, if receive correct, according to high-speed physical shared control channel (High Speed Physical Downlink Shared Control Channel, the information of HS-SCCH) carrying starts to receive high-speed physical downlink shared channel (HS-PDSCH) (High Speed Physical Downlink Shared Channel, HS-PDSCH) data.
If 8 UE are not assigned with dedicated H-RNTI, UE monitors HS-SCCH channel with the H-RNTI of public H-RNTI and BCCH special use simultaneously, if receive correctly, the information of carrying according to HS-SCCH channel starts to receive HS-PDSCH channel data.
From foregoing description, can find out, the in the situation that of 6B, Node B is owing to not knowing to strengthen in this community the ability rating of the UE of CELL_FACH reception, so can only carry out TFRC selection with reference to the lowest capability grade (such as the minimum Category 12 of HS-DSCH physical layer classification) of UE.
What deserves to be explained is: take UMTS system as example, UE ability rating (UE radio access capability) comprises the physical layer ability rating of HS-DSCH physical layer ability rating and E-DCH, UE ability rating correspondence a series of PDCP (Packet Data Convergence Protocol, Paket Data Convergence Protocol), RLC (Radio Link Control, wireless link is controlled), the relevant parameter such as MAC (Medium Access Control, medium access is controlled), PHY (physical layer) layer.Wherein, HS-DSCH physical layer ability rating, defined the UE that supports HSDPA in UMTS, this classification correspondence the parameters such as the modulation system of the maximum HS-DSCH transport block data of a series of supported maximum channel number of codes, minimum continuous T TI receiving ability, single TTI bit number, support and MIMO, for Node B, carry out HSDPA scheduling with reference to used.
For flat framework, adopt Evolution Node B to replace original RNC and Node B, the corresponding module of Evolution Node B wherein (module of Node B as original in correspondence) is under the CELL_FACH state strengthening, do not know the ability rating of UE, have similar problem yet.
Based on this, in embodiments of the present invention, as shown in Figure 1, the schematic diagram of the data transmission method under a kind of CELL_FACH of enhancing state has been proposed.The method comprises:
101, wireless transmitter receives the information relevant with the ability rating of indication UE.
Wherein, described wireless transmitter can be Node B, or the corresponding module (being the module of the function of corresponding former Node B in E-Node B) in the evolved base station E-NodeB in flat framework (Evolution Node B).
The ability rating of UE can refer to the physical layer ability rating of UE, such as, the HS-DSCH physical layer ability classification of UE or E-DCH physical layer ability classification.The information relevant with the ability rating of indication UE can be Frame or signaling, as comprise the HS-DSCH Frame of indication UE ability rating, or comprise the signaling of UE ability rating, or comprise the relevant signaling of ability rating with indication UE, as indicated wireless transmitter when UE goes to CELL_FACH state from CELL_DCH state, preserve the ability rating of UE in signaling.
The information relevant according to the ability rating of above-mentioned indication UE is different, and wireless transmitter can be known the ability rating of UE from explicit information or implicit information.Wherein, explicit information refers to the ability rating that has directly comprised UE in information, as the ability rating that has comprised UE in HS-DSCH Frame or signaling (as NBAP signaling); Implicit information refers to the ability rating that does not directly comprise UE in information, but indirectly makes wireless transmitter know the ability rating of UE.
And when wireless transmitter is specially the correlation module in E-Node B (Evolution Node B), now RNC entity and Node B entity are merged into Evolution Node B, but still according to the concrete function of above-mentioned RNC and Node B, carry out work in Evolution Node B inside.
102, described wireless transmitter is known the ability rating of UE according to the relevant information of ability rating described and indication UE.
Different according to the relevant information of ability rating from indication UE, wireless transmitter knows that the ability rating method of UE is also different.
When this information is explicit information, wireless transmitter is directly resolved information, just can know the ability rating of UE.
When information is implicit expression, refers to the ability rating that does not directly comprise UE in information, but indirectly make wireless transmitter know the ability rating of UE.Assumed wireless R-T unit is Node B, such as, when UE will carry out the transfer of RRC connection status, RNC initiates UE and from CELL_DCH state, turns the NBAP signaling of CELL_FACH state.Due at UE during in CELL_DCH state, Node B has preserved the ability rating of UE in this locality, RNC issues the ability rating of relevant NBAP signaling (as wireless connections removal request signaling) command N ode B preservation (not deleting) UE of Node B, under the CELL_FACH state strengthening, Node B can carry out transfer of data according to the ability rating of the UE preserving, in NBAP signaling the indication of implicit expression the ability rating of corresponding UE in Node B.So wireless transmitter wireless transmitter can be known the ability rating of the local UE preserving.
103, described wireless transmitter carries out transfer of data according to the ability rating of described UE.
Specifically can comprise that wireless transmitter carries out TFRC selection according to the ability classification of UE, and then carry out transfer of data accordingly.
Further describe several modes of the relevant information of ability rating of indication UE below.
Mode one: adopt HS-DSCH Frame (as S-DSCH DATA FRAME TYPE2) to carry the HS-DSCH physical layer ability classification indication of UE (as mobile station MS).
For convenient, understand, the S-DSCH DATAFRAME TYPE2 data frame format of take is below example, and the HS-DSCH DATA FRAME TYPE2 data frame format that contrasts existing 3GPP R7 protocol definition describes.
The example of the HS-DSCH DATA FRAME TYPE2 data frame format in Fig. 2 embodiment of the present invention, is simplified characterization, hereinafter with " FP frame " representative " HS-DSCH DATAFRAME TYPE2 Frame ".The difference of described FP frame is the definition of the 4th byte of FP frame, and concrete difference is as follows:
The 4th byte of the FP frame of existing R7 agreement comprises two parts, FI (FACH Indicator, FACH indication) IE and Spare, and the 4th byte of FP frame in the embodiment of the present invention comprises FI IE, HS-DSCHcategory IE and Spare, totally three parts; Meanwhile, the FI IE of two kinds of FP frames definition and bit bit length are also different, specifically see the following form:
Table 1:
In embodiments of the present invention, in FP frame, defined a new HS-DSCH category IE, be used to indicate the HS-DSCH physical layer ability classification of the object UE of this signaling data frame, be total to 4bits, and when FI IE is " 11 ", HS-DSCH category IE fills in the bits corresponding to the HS-DSCH physical layer category of 3GPP R725.306 protocol definition, now, corresponding relation between the two can be as shown in table 2, otherwise HS-DSCH category IE is filled to be " 0000 ", is equal to the Spare of this byte.
Table 2:
The Spare position residue 2bits of the nybble of the FP frame defining in the embodiment of the present invention, can fill " 00 ", and this 2bits also can be used as the HS-DSCH physical layer classification expansion Spare bit position of follow-up UE.
It should be noted that, the definition of above-mentioned two tables is only a kind of example, should not be construed as the restriction to the embodiment of the present invention, the HS-DSCH physical layer category of 25.306 definition as corresponding in the FP frame HS-DSCH category IE in the embodiment of the present invention also can be not according to regulation in table 2, and there is other variation etc., do not do one by one and repeat herein as space is limited, and other approximate variation should be known to those of ordinary skills.
Like this, in the present embodiment, under the CELL_FACH state strengthening, Node B obtains after the HS-DSCH DATA FRAME TYPE2 Frame of the HS-DSCH physical layer classification that comprises UE, this Frame is resolved, just can obtain the ability rating (being HS-DSCH physical layer classification) of UE, then can carry out data dispatch according to the data transfer mode of the enhancing CELL_FACH of 3GPP R7 standard agreement definition, and transmit data in corresponding channel.
Mode two: the ability rating that comprises UE of demonstration or implicit expression in signaling.Described signaling can be specifically NBAP signaling.
1) explicit in the situation that, wireless transmitter obtains the NBAP signaling of the physical layer classification that comprises UE, this signaling is resolved, obtain the ability rating of UE wherein, then can carry out data dispatch according to the data transfer mode of the enhancing CELL_FACH of 3GPP R7 standard agreement definition, and transmit data in corresponding channel.
2) when the situation of implicit expression generally occurs in connection status transfer, as when UE turns CELL_FACH state from CELL_DCH state, RNC sends the NBAP signaling that comprises wireless connections removal request (Radio Link Deletion Request) to Node B, in this signaling, be originally by deleting the former radio link parameter information (being the radio link parameter information under CELL_DCH state) of this UE, to reconfigure the radio link parameter information under CELL_FACH state on Node B.Due under CELL_DCH state, the radio link parameter information of preserving in Node B has comprised the physical layer ability classification of UE, so in embodiments of the present invention, when UE turns CELL_FACH state from CELL_DCH state, the physical layer ability classification of indicating Node B to preserve UE in the NBAP signaling that RNC sends to NodeB, makes Node B also can know the ability rating of UE under the CELL_FACH state strengthening.In addition, in NBAP signaling, even also can comprise other parameter configuration of HS-DSCH under original CELL DCH state, to support the UE under CELL_FACH state to obtain as much as possible HS-DSCH transmission rate higher.With a concrete NBAP signaling, be described further below.
The Radio Link Deletion Request signaling of take in NBAP signaling is example, when UE turns CELL_FACH state from CELL_DCH state, RNC sends Radio Link Deletion Request signaling to delete the relevant wireless link parameter under CELL_DCH state to Node B.
In the present embodiment, in order to make Node B can know the ability rating of UE, in Radio Link Deletion Request signaling, increase the UE RRC state transitions indication (RRC State Transition Indictor) that this deletes chain.Wherein, RRC State Transition Indictor is defined as follows table:
