Description
Technical field
The present invention relates to WCDMA and strengthen wireless technical field, particularly have the method for subscriber equipment dynamic-configuration receiver in wireless access network of two above receiver branches.
Background technology
Normal structure 3GPP is current to discuss the theme of dynamic-configuration receiver under the prerequisite that UE (subscriber equipment) satisfies quality of service requirement, and this theme is applicable to the UE of a plurality of receiver of configuration branch.Road FOR ALL WE KNOW, in the network environment of reality, the signal quality under the varying environment there are differences, and the extraordinary zone of signal quality is arranged, the better quality of signal zone is arranged, and also has signal quality relatively poor even almost do not have a zone of signal.UE for a plurality of receiver of configuration branch, in the subregion, the signal quality of its reception has exceeded quality of service requirement, at this moment, UE often only needs one of use or part receiver branch just can obtain satisfied service, and unnecessary receiver branch only can bring the consumption of handset processes energy.So, from another angle, if we are closed portion receiver branch under service quality can guaranteed prerequisite, just can reduce the consumption of UE energy, thereby prolong the time that UE uses service, it is especially necessary that this meaning seems when facing a severe challenge for following multimedia service UE battery.
The discussion of 3GPP concentrates on that UE can realize this type of receiver Dynamic Reconfiguration in MBMS (multimedia broadcast multicast service) business scenario, the automatic configuring receiver of UE refers to that UE is by measuring received signal quality, according to the automatic configuring receiver number of branches of specific control algolithm, promptly double-receiver UE can close one of them receiver branch under the prerequisite that guarantees service quality.But, discussion is incomplete, be mainly reflected in: 3GPP at present at application scenarios only be the MBMS business, and think that HSDPA (high speed downlink packet access technology), EDCH (enhancing dedicated channel) wait other scene can not be suitable for UE dynamic-configuration receiver technology, reason is that the wireless signal variation in other scene is rapid, power control requires very high, is difficult to judge the opportunity of closing or opening receiver branch.3GPP considers that at present UE passes through the dynamic configuring receiver of self detection signal quality, is suitable for the MBMS broadcasting service, so long as the place that the MBMS broadcasting service covers all is suitable for.Because for the MBMS broadcasting service, UE does not have up connection, power control requires lower, and the UE received signal changes less relatively, does not require that UE frequently opens or closes receiver branch and just can obtain the service quality assurance.But for non-MBMS scene, not all zone can both be suitable for this technology, HSDPA for example, UE and base station two-way communication, the variation of received signal quality is very outstanding with wireless environment influence, and is bad when especially the cell edge signal may fashion in the subregion of the network coverage, and changes violent, if this moment, UE dynamic-configuration receiver can cause frequent switching, influence QoS of customer on the contrary.
But, the MBMS scene is not unique suitable scene, in other non-MBMS network scenarios such as HSDPA, EDCH, also exist the subregion can use UE dynamic-configuration receiver technology, these zones comprise zone that Radio Link loss between indoor overlay area and the base station is little etc., and these regional signal qualitys all are extraordinary usually, signal changes also little, more stable, meet the requirement of UE dynamic-configuration receiver, and the distribution in these zones is more at random.The method that in these non-MBMS scenes, does not also have the automatic configuring receiver of UE at present.
Summary of the invention
Technical problem to be solved by this invention provides the method for a kind of subscriber equipment automatic configuring receiver when non-MBMS scene, makes subscriber equipment during signal stabilization regional, can realize automatic configuring receiver in non-MBMS scene.
In order to solve the problems of the technologies described above, the invention provides the method for a kind of subscriber equipment automatic configuring receiver when non-MBMS scene, may further comprise the steps:
(a) judge whether UE has receiver to be in closed condition, if, execution in step (c), when UE does not have receiver and is in closed condition, execution in step (b);
(b) if the Block Error Rate of judging subscriber equipment less than the Block Error Rate thresholding, and received signal quality is greater than signal quality thresholding a period of time, then according to each receiver received signal ability power, preferentially close the weak receiver branch of received signal ability, perhaps, be after closing one or several receiver branch according to judgement, can satisfy demand on signal quality after the signal quality of remaining receiver branch merges and come closed portion receiver branch; Otherwise, return step (a); The evaluation method of the Block Error Rate of described subscriber equipment is as follows: if CRC CRC failure, the then Block Error Rate valuation=old Block Error Rate valuation+α of (1-α) *, otherwise, the Block Error Rate valuation=old Block Error Rate valuation of (1-α) *, wherein α is a correction factor;
(c) if the Block Error Rate of judging subscriber equipment greater than the Block Error Rate thresholding, and received signal quality then opens part receiver branch less than the signal quality thresholding, otherwise, return step (a).
Further, said method also can have following characteristics: in described step (b), timer is set picks up counting during greater than the signal quality thresholding, stop during less than quality threshold or UE closed portion receiver branch up to described received signal quality at described received signal quality.
Further, said method also can have following characteristics: in described step (b), when the Block Error Rate of described subscriber equipment during less than the Block Error Rate thresholding, reduce the signal quality thresholding, with current received signal quality with reduce after the signal quality thresholding compare.
Further, said method also can have following characteristics: in described step (c), when the Block Error Rate of described subscriber equipment during greater than the Block Error Rate thresholding, improve the signal quality thresholding, with current received signal quality with improve after the signal quality thresholding compare.
Further, said method also can have following characteristics: in described step (c), the described standard of opening part receiver branch is that can the signal quality of all receiver branches satisfy demand on signal quality after merging after one or several receiver branch was opened in judgement.
The present invention can effectively prolong UE service time, save the terminal energy consumption, and the epoch that seriously are subject to the end cell ability at mobile multimedia UE service time are very significant.The new function that the configuration UE receiver can be used as mobile phone realizes, also can be used as the new value-added service that operator provides for the client, therefore, no matter is that equipment manufacturers or operator can therefrom make a profit.
Description of drawings
Fig. 1 is a UE configuring receiver branch sketch plan;
Fig. 2 is the control flow chart of the automatic configuring receiver of UE under non-MBMS scene.
Embodiment
Be example with double-receiver UE below, the flow process of automatic configuring receiver is described.The layoutprocedure of multi-receiver UE similarly.
The control flow of double-receiver UE under non-MBMS scene may further comprise the steps as shown in Figure 2:
Estimating that BLER is one of necessary condition of follow-up judgement, is the basis of subsequent step.UE estimates one of method of block error rate BLER: if CRC (CRC) fails, the old BLER_Estimate+ α of BLER_Estimate=(1-α) * then, otherwise, the old BLER_Estimate of BLER_Estimate=(1-α) *, wherein α is a correction factor.BLER method of estimation when CRC failure takes place and failure do not take place is different, does like this to help follow-up judgement, the sensitivity that can improve algorithm.But the method for estimating Block Error Rate is not limited thereto.
UE estimation Block Error Rate is not limited to carry out at this moment, obtains before judging Block Error Rate being carried out thresholding as long as guarantee.
Whether step 203 judges the BLER value less than BLER threshold value B LER_Target, if, carry out next step, otherwise, step 201 returned;
Wherein, Q is the self-adapting signal quality threshold, and δ is one to be increased or reduction, needs by emulation or definite in actual applications size.Can change according to quality of service requirement, operator can be provided with different values according to different network condition.
Perhaps quality threshold is not adjusted, directly carried out next step.
Whether step 205 judges collection of letters quality-class (or claiming received signal quality) Rx Quality greater than quality threshold Q, if, carry out next step, otherwise, to the timer zero clearing, return step 201;
After the Timer zero clearing, as Rx Quality during for the first time greater than Q, Timer picks up counting, as long as Rx Quality is greater than Q, Timer is adding up timing always, stops less than Q or when being transformed into the single-receiver pattern up to Rx Quality.That is to say, Timer calculates be Rx Quality continuously greater than the cumulative time of Q, have only Rx Quality after a period of time, just to think that signal quality is stable, just allows to close receiver branch greater than Q continuously.T1 is a threshold value, needs by emulation or definite in actual applications size.
For having a plurality of receiver UE of branch, can be according to the power of each receiver received signal ability, which or which receiver is closed in decision, such as the receiver of preferentially closing a little less than the received signal ability, perhaps when combined signal, need make judgement, judge close one or several receiver branch after, can meet the demands after the signal quality of remaining receiver branch merges, other judge's rules also can be set as required.
Whether step 208 judges the BLER value greater than BLER_Target, if, carry out next step, otherwise, step 201 returned;
The Q of processing when equaling to(for) Rx Quality, present embodiment just provide a kind of situation, as limiting, promptly also it can not included in the step 205.
For having a plurality of receiver UE of branch, can when combined signal, need make judgement, after one or several receiver branch was opened in judgement, can the signal quality of these receiver branches satisfy quality of service requirement after merging.
In sum, adopt the method for the invention, following advantage arranged:
(1) in the more stable scene of MBMS, indoor environment or other signal quality, configuration is many The UE of receiver branch (more than two) can connect by self detecting reception service quality closed portion Receipts machine branch, thus the UE energy consumption saved, prolong UE service time, for alleviating multimedia service UE The battery capability defect is very useful with satisfying user's particular demands;
(2) (this thresholding is enough to guarantee that the UE closed portion receives when the UE signal quality surpasses certain thresholding Still can reach quality of service requirement during machine branch) duration when reaching certain numerical value, UE also can With autoshutdown part receiver branch; Need to arrange suitable parameter this moment, guarantees that UE closes or beats The behavior of opening receiver branch occurs in the more stable scene of indoor covering or other signal quality, and Frequent switching can not take place;
