A kind of method that improves group operation online user quantity
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of method that improves group operation online user quantity.
Background technology
In RAN29 meeting of 3GPP, the job of a Continuous connectivityfor packet data users (forever online) has been set up in approval, and this job wishes that the target of reaching is: the number that improves the Packet Service online user.
The source of described job is: for some business, its traffic models is the interrupted transmissions of data, in business procedure, the interrupted number of times of data is very many, such as the web page browsing business, generally be that download webpage and browsing page hocket, promptly have the transmission of transfer of data and free of data to hocket.Also for a long time fragmentary transfer of data of some service needed if having or not transfer of data, is all kept same state, and also Resources allocation when not having transfer of data will be wasted resource; If when transfer of data begins, connect, when number pass to finish, discharge and connect, will cause the frequent foundation and the release that connect, the load of increase system control increases data transmission delay.
At the problems referred to above, permanent online job wishes to adopt certain technology, makes UE (subscriber equipment) constantly idle what do not have data to send, can remain on CELL_DCH state (connected state) for a long time, few again simultaneously resource of eating dishes without rice or wine that consumes.
In existing WCDMA (Wideband Code Division Multiple Access (WCDMA)) agreement, when UE is in the CELL_DCH state, up DPCCH (Dedicated Physical Control Channel) is bound to send, and will bring uplink interference to other users like this, makes the number of users that is in connected state be restricted.
Therefore, mainly having proposed DPCCH gating (DPCCH sends at interval) and SIR Target (signal-to-noise target value) among the disclosed 3GPP TR 25.903V0.0.3 in October, 2005 3GPP reduces by two kinds of schemes and solves the problems referred to above.
Described DPCCH gating scheme is with reference to shown in Figure 1, when the non-activated state of data, only at the parton frame period of partial frame property ground transmitting uplink control channel; When the data transmit status, the normal transmission ascending control channel.This method can promote the number of free of data transmission user in the sub-district, and this scheme can also promote the capacity of HSPA (high-speed packet access) when carrying IMS (integrated multimedia subsystem) real time business.
But, because the discontinuous transmission of upstream data causes this scheme to have following defective:
1) descending F-DPCH (burst DPCH) the power control meeting of channel is subjected to the influence of up discontinuous transmission;
2) channel estimation process during uplink demodulation can be affected, and like this in order to realize the synchronous/asynchronous detection of physical layer, just requires to adopt higher transmitting power when sending DPCCH, has limited the degree of performance improvement.
The scheme that described SIR Target reduces is specially: when up when not having data to send, the base station initiatively reduces SIR Target, make the transmitting power of DPCCH be reduced to the degree that to keep inner-loop power control, close the transmission of up CQI (channel quality indication) simultaneously.
The scheme that above-mentioned SIR Target reduces, because up DPCCH remains continuous transmission, though required DPCCH power has reduced, the up-link capacity that improves is still limited.

Embodiment
Core concept of the present invention provides a kind of method that improves group operation online user quantity, when the user of Packet Service does not have transfer of data, enters the non-activated state of HSPA, does not consume descending and ascending idle wireless resource fully.
The invention provides a kind of method that improves group operation online user quantity, the specific implementation process is as described below:
Step 1: when the user did not have transfer of data, network side and end side entered the non-activated state of HSPA;
HSDPA (high speed downlink packet access) Serving cell and the unification of HSUPA (high speed uplink packet access) Serving cell with HSPA user in the present embodiment are the HSPA Serving cell;
At the appointed time, the base station that comprises HSPA user's Serving cell detects this HSPA user's high speed uplink does not have valid data with following provisional capital, HSDPA (high speed downlink packet access) formation is empty, when never detecting simultaneously effective signal on the E-DPCCH (enhancing Dedicated Physical Control Channel), then the base station is by HS-SCCH (High-Speed Shared Control Channel) signaling UE, enter the non-activated state of HSPA, after UE receives described HS-SCCH signaling, ACK (confirming response) by HS-DPCCH (High-Speed Dedicated Physical Control Channel) responds the base station, expression is to the affirmation of the non-activated state of this HSPA, and then the network side at the end side at UE place and place, base station enters non-activated state; At this moment, up E-DCH (enhancing dedicated channel) demodulation resource frees out, and uses for other users, is convenient to hardware resource management, and the AG (absolute grant) that makes E-DCH is 0 or INACTIVE (non-activation);
Step 2: under the non-activated state of HSPA, up-downgoing stops to send the signal of whole dedicated channels;
Under the non-activated state of HSPA, described UE stops to send up DPCCH, E-DPCCH, E-DPDCH (enhancing Dedicated Physical Data Channel), HS-DPCCH etc., the transmitting power that the UE record is final;
Simultaneously, descending also the stopping of described UE correspondence sends whole signals, comprises F-DPCH (burst DPCH), final down transmitting power and the CQI of base station record;
Step 3: under the non-activated state of HSPA, regularly detect the intensity of down-bound pilot frequency signal by UE, carry out the power control recovery operation, make the transmitting power of terminal and base station side satisfy the receiving terminal channel ratio, in resume data transmission, can shorten the time that transfer of data is recovered like this;
UE regularly detects the intensity of down-bound pilot frequency signal, when pilot signal strength change to surpass to a certain degree, carries out the power control recovery operation, described power control recovery operation can for:
UE resends the E-DPCCH signal, by E-TFCI coding special in the E-DPCCH signal, realizes with base station side synchronous as complete 0;
When the base station detects the E-DPCCH signal, recover normal F-DPCH (burst DPCH) and send, and by E-HICH (mixed automatic re-transmission indicating channel) channel, notice UE has detected the E-DPCCH signal;
UE detects the uplink and downlink power control and restrains, and the E-HICH channel received that after the confirmation signal, UE stops to send synchronizing signal, and the UE end reverts to the non-activated state of HSPA;
Afterwards, the base station is detected less than the E-DPCCH signal, and the base station also returns to the non-activated state of HSPA.
HS-SCCH also can be passed through again in this process base station, and indication UE enters the non-activated state of HSPA, and concrete operations comprise:
When UE detects down-bound pilot frequency signal intensity above prescribed limit, send DPCCH and carry out simultaneous operation to the base station;
Detect the signal of described UE transmission when the base station after, recover normal F-DPCH and send; The base station detects the up-downgoing power control and restrains, and by HS-SCCH signaling UE, enters the non-activated state of HSPA;
After UE receives described HS-SCCH signaling,, confirm to recover the non-activated state of HSPA by the ACK response base station of HS-DPCCH;
The base station receives the ACK back-signalling of UE, recovers the non-activated state of HSPA.
The mode of power control is at a slow speed adopted in the provisional capital about in this process, is 500Hz or 300Hz as the power control frequency;
CQI information also needs to upgrade, and also can transmit by E-DPCCH in this state;
Step 4: under the non-activated state of HSPA, carry out the detection of loss of mains of link;
Concrete detection of loss of mains process comprises:
When having data to send,, then determine UE step-out when descending, initiate link by the base station and discharge if can not receive the feedback of UE at the appointed time always;
When having data to send, if can not receive the feedback of base station at the appointed time always, then UE can determine local terminal step-out when up, initiates RRC by the RACH channel and discharges or rebulid;
When UE initiated power control recovery process, if can not receive the feedback of base station at the appointed time always, then UE can determine step-out, initiated RRC (Radio Resource control) by RACH (Random Access Channel) channel and discharged or rebulid;
Step 5: when under the non-activated state of HSPA, having detected the data transmission, switch to the HSPA state of activation;
When to switch the promoter be descending, described operation specifically was divided into following two kinds of situations:
When the base station detects when having data to send in the HSDPA formation, recovering normal downlink data immediately sends, open downstream transmitter, begin to send the signal of F-DPCH channel, UE detects the signal of F-DPCH channel, then opens upstream transmitter, recovers the transmission of up DPCCH signal, the base station detects the DPCCH signal that UE sends, and has then finished the process that switches to the HSPA state of activation from the HSPA unactivated state;
Perhaps, have data to send in the HSDPA formation when the base station detects, recover normal downlink data immediately and send, open downstream transmitter, begin to send the signal of F-DPCH channel, and by the HS-SCCH signaling, UE is descending has data to send for notice.After UE receives the HS-SCCH signaling, then open upstream transmitter, recover the transmission of up DPCCH signal, by HS-DPCCH channel feedback confirmation, the base station receives the affirmation information on the HS-DPCCH channel, has then finished the process that switches to the HSPA state of activation from the HSPA unactivated state.
Initial Trans PDPCCH after UE activates is: the transmitting power PDPCCH last of UE record when entering the non-activated state of HSPA, add from UE and enter the non-activated state of HSPA, arrive the variation delta RTWP of the total bandwidth power RTWP that receives during UE recovers to launch, add from UE and enter the non-activated state of HSPA, the Δ CPICH RSCP of the signal strength signal intensity RSCP variable quantity that the Common Pilot Channel CPICH signal during UE recovery emission receives, i.e. PDPCCH=PDPCCH last+ Δ RTWP+ Δ CPICH RSCP; Or,
Initial Trans PDPCCH after UE activates is: calculate acquisition according to the open loop power control principle, the process when computational methods are initially set up with link is identical.
When to switch the promoter be up, described operation specifically was divided into following two kinds of situations:
When detecting, UE have data to send in the HSUPA formation, recovering normal upstream data immediately sends, open upstream transmitter, begin to send the signal of DPCCH channel, the base station detects the DPCCH signal that UE sends, and then opens downstream transmitter, recovers the transmission of F-DPCH signal, UE detects the F-DPCH signal that the base station sends, and has then finished the process that switches to the HSPA state of activation from the HSPA unactivated state.
Perhaps, there are data to send in the HSUPA formation, recover normal upstream data immediately and send when UE detects, open upstream transmitter, begin to send the signal of DPCCH channel, and by the E-DPCCH channel, application sends data to the base station, after the base station receives the E-DPCCH signal, then open downstream transmitter, recover descending data and send, on E-HICH, confirm, after UE correctly receives the E-HICH signal, then finished the process that switches to the HSPA state of activation from the HSPA unactivated state.
The Initial Trans PF-DPCH of base station is: the transmitting power PF-DPCH last of base station record when entering the non-activated state of HSPA adds power bias configuration parameter Δ power, i.e. PF-DPCH=PF-DPCH last+ Δ power; Or, cover certain constant power that requires setting according to common signal channel, dispose by high-level signaling.
In sum, when the user that the present invention has realized at Packet Service does not have data to transmit, enter the non-activated state of HSPA, do not consume descending and ascending idle wireless resource fully.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
