Description
Technical field
The present invention relates to the communications field, in particular to a kind of up-link wireless public resource method for reconfiguration and device.
Background technology
In WCDMA (Wideband Code Division Multiple Access, referred to as WCDMA) net
In network, and universal land radio access web (Universal Terrestrial Radio Access Network, referred to as
UTRAN radio network controller (Radio Network Controller, referred to as RNC) and base station (NodeB, abbreviation) are included
NB) two kinds of basic network elements, abbreviation WCDMA networks.(High is accessed in the long-term evolving network high-speed packet based on WCDMA networks
Speed Packet Access, referred to as HSPA+) in network, many new functions and characteristic are with new edition from one generation to the next
This is gradually added thereto.Such as high-speed downstream receives link packet access (High Speed Downlink Packet
Access, referred to as HSDPA), high speed uplink transmission link packet access (High Speed Uplink Packet Access,
Referred to as HSUPA), multiple antennas multiple-input and multiple-output (Multiple Input Multiple Output, referred to as MIMO) skill
Art, multi carrier wave high-speed downlink packet access (Multi Carrier-High speed downlink packet access, letter
Referred to as MC-HSDPA) and constantly enhanced RRC status (RRC state radio resource
Control) administrative mechanism and ability.New function characteristic in these HSPA+ systems, what is had causes terminal (UE) in proprietary state
Cell_DCH can more efficiently use wireless specific resource, so that terminal up-downgoing data transmission rate is continuously available multiplication and carried
It is high；What is had enables terminal more efficiently to use wireless public resource in public state Cell_FACH, so that terminal up-downgoing
Data transmission rate and transmission delay can also obtain performance improvement.
Before HSPA+ versions 8, terminal only possesses very weak transmitting uplink data ability in Cell_FACH states.Network
The Physical Random Access Channel resource (PRACH resource) limited by being configured in each serving cell so that terminal
, can only be in a Transmission Time Interval (Transmission Time after each successful random access procedure
Interval, referred to as TTI) length one data block (Transport Block, referred to as TB) of interior transmission.When this TB is passed
Be totally lost complete, regardless of its uplink result, terminal will all discharge before that used by PRACH resource, to stay
Used to other terminal.This mode that uplink is carried out using PRACH resource, is relatively adapted to terminal uplink and sent
There are the TB of less data volume, particularly one just carryings enough in caching.Otherwise terminal must undergo one or more again
Random access procedure, remaining data, network is sent to by the way that one and another TB is up.
In order to strengthen terminal in Cell_FACH state upstream data sending performances, since HSPA+ versions 8, partly there is enhancing
The terminal of uplink capacity possesses so-called in ability of the Cell_FACH states using enhancing dedicated channel E-DCH.Network passes through every
32 public enhancing dedicated channel resources (Common E-DCH Resource) are configured in one serving cell so that terminal energy
Enough after each successful random access procedure, multiple data block TB are transmitted in multiple TTI length being endowed.When this
After a little TB end of transmissions, terminal will strengthen absolute grant channel E-AGCH resource release commands or implicit based on base station down
Time time-out mode discharges the Common E-DCH Resource used before, is used with leaving other terminal for.It is this to utilize
Common E-DCH Resource carry out the mode of transmitting uplink data, are relatively adapted to have larger in terminal uplink transmission caching
Data volume, the particularly data volume that must could be carried by multiple TB.
It is why more efficient than PRACH resource using Common E-DCH Resource, mainly have following several
Individual reason：
1：The Common E-DCH Resource that Cell_FACH states are used, inherit E-DCH in proprietary state Cell_DCH
Most of feature that Resource is used, such as terminal uplink data, which are sent, must receive the fast power authorization control of base station, energy
Enough rapid feedbacks according to base station, carry out data Fast retransmission.And utilize PRACH resource terminal uplink data to send
It is, towards CRNC (Control Radio Network Controller, controlling radio network controller), initially to send work(
Rate takes open loop rough estimate mode, and whole up transmission process does not have any close-loop power control, without wireless chain control layer
(Radio Link Control, RLC) feeds back, so in order to ensure that data send quality, generally conservatively selecting less TB.
2：The corresponding TTI of Common E-DCH Resource have two kinds, and 2ms and 10ms, wherein 10ms are applied in terminal
The less situation of the net greatest service rate (Headroom power) of row, to strengthen TB transmission reliabilities, but TB transmission delays are larger；2ms
Suitable for the situation that the net greatest service rate of terminal uplink (Headroom power) is larger, TB transmission delays are smaller.And PRACH
The corresponding TTI of resource also have two kinds, 10ms and 20ms, it is clear that hair generally more up than Common E-DCH Resource
Send efficiency poor.
3：Because Common E-DCH Resource can be held after a successful random access procedure by terminal
It is continuous to use multiple TTI time spans, and PRACH resource must will discharge after a TTI, it is clear that Stochastic accessing
The time consuming cost of process institute and meaning are not balanced by real data transfer.
For these reasons, it be also provided when terminal possesses using Common E-DCH Resource abilities and network
Under conditions of related Common E-DCH Resource resources, terminal always selects Common E-DCH Resource, without
Consider to use any PRACH resource.Such as terminal has a transmitting uplink data demand, no matter this data volume size cases,
Its first random access procedure always log on distributes some Common E-DCH Resource to it.If first
Random access procedure failure (and other are while signal collision occurs for the terminal of Stochastic accessing) or first random access procedure
Even if having succeeded but have failed (Common E-DCH Resource when competition obtains Common E-DCH Resource
It is actual also to be succeeded by another shared by the terminal of Stochastic accessing), terminal was had to wait for after a period of time, reattempted second
Individual Stochastic accessing and Common E-DCH Resource competitions are obtained, by that analogy, until terminal can successfully compete acquisition
To one's own Common E-DCH Resource, the data uplink in caching could be sent afterwards.Whole mistake
Journey, even if PRACH resource resources are idle, terminal does not allow rollback (Fallback) to use PRACH resource.
In order to optimize said process, HSPA+ versions 11, which are being studied, to be run into Common E-DCH Resource in terminal and gathers around
How to be retracted when plug using PRACH resource.Due to base station, some serving cell can be understood in real time currently up
The service condition of wireless public resource, therefore NodeB can be by physical layer command (such as with AICH channel bearing rollback orders
Indicate), should to instruct terminal after Stochastic accessing and Common E-DCH Resource competition acquisition failures is run into
Retract using PRACH resource.Advantage of this is that：The terminal that part is retracted by base station commands in a short time, will not
The contention of Common E-DCH Resource resources, therefore Common E-DCH Resource resource congestion situation meetings are participated in again
Relaxed.Generally, terminal is receiving base station rollback order instruction, after a complete PRACH resource, is just not required to
Any order is wanted to indicate, next time, automatic upgrading (Upgrade) returned to Common E-DCH Resource resources, then again might
Start above-mentioned rollback flow.
If terminal is in time period, the rollback order of base station is repeatedly received, continually from Common E-DCH
Resource resource using status return back to PRACH resource resource using status, although this can be helped in network neutralizing
The situation of the wireless public resource congestion of row, but to experience transmitting uplink data delay suddenly big or suddenly small by user, so as to influence user
