Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
Use part receiver branch to the aforesaid multi-receiver UE of branch, when just being enough to obtain the situation of satisfied service, the present invention proposes following improvement thought:
When the duration that the UE signal quality surpasses the thresholding that is provided with in advance reached certain numerical value, UE is closed portion receiver branch automatically, thereby saves the UE energy consumption, the prolongation UE available machine time.This preset thresholding still can reach quality of service requirement in the time of should being enough to guarantee UE closed portion receiver branch.This moment, preset thresholding should be a relatively reasonable parameter, guaranteed that behavior that UE closed or opened receiver branch occurs in the more stable scene of indoor covering or other signal qualitys, frequent situation about switching can not occur.
Fig. 1 shows the sketch map that UE forms embodiment, merges the module except comprising signal, also comprises:
Measurement module is used to obtain the total signal receiving quality of all receiver branches, and signal receiving quality is sent to judge module;
Judge module; Link to each other with measurement module; Be used to judge whether UE has closed part receiver branch; And judge and the magnitude relationship of signal receiving quality and preset signal quality threshold value also to be used to judge the time that magnitude relationship kept of UE signal receiving quality and signal quality thresholding and the magnitude relationship of the time gate limit value of presetting;
Control module links to each other with judge module, is used for the judged result according to judge module, and closed portion receiver branch perhaps opens the part or all of receiver enhancing UE of branch and receives quality of signals to practice thrift the UE energy consumption under the prerequisite that guarantees service quality.
Closing the part receiver branch of UE, during service that UE still can be satisfied with, a plurality of receiver branch of UE; Like receiver branch 1, receiver branch 2 ...; The N of receiver branch (N >=3) is carrying out the measurement of each branch signal quality through measurement module, and after the signal quality judgement through judge module; Under the control of control module, close part receiver branch wherein; All the other not pent receiver branches are fed to signal and merge module and merge processing, and support that UE works on, and guarantee that UE obtains satisfied service.
For the MBMS broadcasting service, UE does not have up connection, and power control requires lower, and it is less relatively that UE receives the signal variation, does not require that UE frequently opens or closes receiver branch and just can obtain the service quality assurance.But in other network scenarios, HSDPA for example, UE and base station two-way communication, the variation of signal receiving quality is stronger with the wireless environment influence.Bad when the cell edge especially in the subregion of the network coverage, signal maybe fashions, and change frequent and violent.If this moment, UE dynamic-configuration receiver can cause frequent switching, influence QoS of customer on the contrary.Also promptly in other network scenarios such as HSDPA, EDCH, only exist the subregion can use UE dynamic-configuration receiver technology.These zones comprise zone that Radio Link loss between zone that indoor covering is good and the base station is little etc., and these regional distributions are more at random.Therefore, when UE carries out the automatic configuration of receiver under non-MBMS scene, to consider that not only receiver branch receives quality of signals, also will consider the stability of signal quality.
Reduce the energy consumption of UE through automatic closed portion receiver branch; Perhaps in closed portion receiver branch, improve service quality through opening buttoned-up receiver branch; All need detect, and close automatically or opening section receiver branch according to testing result to the received signal of UE.Below respectively to the automatic configuring receiver of UE under the MBMS scene and under non-MBMS scene the automatic configuring receiver both of these case of UE describe.
Fig. 2 shows the embodiment flow process of the inventive method under the MBMS scene, comprises the steps:
Step 201:UE judges whether the setting of automatic configuring receiver opens.If opened then execution in step 202; Otherwise do not carry out the operation of automatic configuring receiver, process ends.
Step 202:UE obtains the total signal of all receiver branches through its inner measurement module and receives BLER (Block Error Rate, bLock error rate) estimated value, and the BLER estimated value is sent to the inner judge module of UE.
BLock error rate wherein also can be other forms of received signal quality, such as signal-to-jamming ratio (Signal-to-Interference Ratio, be called for short SIR) etc.In the present embodiment, received signal quality all is representative with the bLock error rate.
Step 203: judge module judges whether UE has closed the part branch of receiver after receiving the BLER estimated value.If all receiver branches of UE all are in opening, then change step 204; If current existing part receiver branch is in closed condition, then change step 206.
Step 204: judge module judges that further whether the BLER estimated value close THRESHOLD ESTIMATION value K51 less than one preset first.Signal quality thresholding K51 is the empirical value that has certain redundancy, if expression be the signal quality that receives of UE less than this value, think that then the service quality that UE provides belongs to better, can satisfy user's needs; If be equal to or greater than this value, think that then the service that UE provides is relatively poor, can not satisfy user's needs.Judged result is then changeed step 205 if the BLER estimated value is closed THRESHOLD ESTIMATION value K51 less than first; Otherwise after through the preset time interval, return step 201 and continue to carry out.
The control module of step 205:UE is according to the judged result of judge module, closed portion receiver branch under the prerequisite that guarantees service quality, and after the preset time interval, return step 201 and continue to carry out.
Step 206: judge module judges that further the BLER estimated value is whether greater than another preset THRESHOLD ESTIMATION value K52 that opens.If what open that THRESHOLD ESTIMATION value K52 representes is that the signal quality that UE receives is equal to or less than this value, think that then the service quality that UE provides belongs to better, can satisfy user's needs; If greater than this value, think that then the service that UE provides is relatively poor, can not satisfy user's needs.Judged result is if the BLER estimated value greater than opening THRESHOLD ESTIMATION value K52, is then changeed step 207; Otherwise changeing step 208 continues to carry out.
Step 207: because the existing receiver branch deficiency that is in opening thinks that the user provides satisfied service; Therefore the control module of UE is opened according to the part or all of receiver branch that the judged result of judge module will be in closed condition; Strengthen the signal that UE receives, improve service quality.Afterwards, after through the preset time interval, return step 201 and continue to carry out.
Step 208: judge module judges that further whether the BLER estimated value close THRESHOLD ESTIMATION value K53 less than one preset second.Because the BLER estimated value is equal to or less than K52, also just mean the existing received signal of receiver branch that is in opening, satisfy quality of service requirement.Therefore for multi-receiver branch (more than two s') UE, can also further close the part receiver branch that is in the opening, reach the purpose of further reduction UE energy consumption.
If BLER estimates that limit value K53 representes be the signal quality that receives of UE less than this value, think that then service that UE provides satisfies user's needs; Otherwise just think that service that UE provides can not satisfy user's needs.
The judged result of judge module is then changeed step 209 if the BLER estimated value is closed THRESHOLD ESTIMATION value K53 less than second; Otherwise after through the preset time interval, return step 201 and continue to carry out.
The control module of step 209:UE is according to the judged result of judge module, further under the prerequisite that guarantees service quality, and the receiver branch that the shutdown signal quality of reception is relatively poor, and after the preset time interval, return step 201 and continue to carry out.
In the above-mentioned flow process, the control module of UE is when closed portion receiver branch, and at first closed portion receiver branch is perhaps selected according to the user by the poorest receiver branch of the shutdown signal quality of reception; Correspondingly, when opening receiver branch, also can select to carry out opening operation according to the user.
In the arbitrary steps of above-mentioned flow process, the user of UE also is the user closes automatic configuring receiver at any time through menu or dedicated button setting.If the user has closed the setting of automatic configuration, then UE just can not carry out the automatic of receiver and disposed.
Fig. 3 shows the embodiment flow process of the inventive method under non-MBMS scene, comprises the steps:
Step 301:UE judges whether the setting of automatic configuring receiver opens.If opened then execution in step 302; Otherwise not automatic configuring receiver, process ends.
Step 302:UE passes through the BLER (Block ErrorRate, bLock error rate) that its inner measurement module estimated signal receives, and the BLER estimated value is sent to the inner judge module of UE.
BLock error rate wherein also can be other forms of received signal quality, such as signal-to-jamming ratio (Signal-to-Interference Ratio, be called for short SIR) etc.In the present embodiment, received signal quality all is representative with the bLock error rate.
Step 303: judge module judges whether UE has closed the part branch of receiver after receiving the BLER estimated value.If all receiver branches of UE all are in opening, then change step 304; If current existing part receiver branch is in closed condition, then change step 306.
Step 304: judge module judges that further whether the BLER estimated value close THRESHOLD ESTIMATION value K51 less than one preset first, and whether the BLER estimated value of UE closes time T that THRESHOLD ESTIMATION value K51 kept greater than one first shut-in time threshold T 61 less than first.
Owing under non-MBMS scenes such as HSDPA, carry out two-way communication between UE and the base station, the variation of signal receiving quality is stronger with the wireless environment influence, the variation of the signal quality that some is regional even also very frequent.Therefore need judge the time T that the BLER estimated value is kept.If the BLER estimated value less than first close THRESHOLD ESTIMATION value K51 the time T that this state kept greater than first a preset shut-in time threshold T 61; Think that then the service quality that UE provides is stable, when closed portion receiver branch, still customer satisfaction system service can be provided; Otherwise just think service that UE provides and unstable.
Judged result is if the BLER estimated value is closed THRESHOLD ESTIMATION value K51 less than first, and the BLER estimated value closes time T that THRESHOLD ESTIMATION value K51 kept greater than the first shut-in time threshold T 61 less than first, then changes step 305; Otherwise after through the preset time interval, return step 301 and continue to carry out.
The control module of step 305:UE is closed the relatively poor receiver branch of signal receiving quality according to the judged result of judge module under the prerequisite that guarantees service quality, and after the preset time interval, returns step 301 and continue to carry out.
Step 306: judge module judges that further the BLER estimated value is whether greater than another preset THRESHOLD ESTIMATION value K52 that opens, if the BLER estimated value is then changeed step 307 greater than opening THRESHOLD ESTIMATION value K52; Otherwise changeing step 308 continues to carry out.
The control module of step 307:UE is all opened according to the receiver branch that the judged result of judge module will be in closed condition, and after through the preset time interval, returns step 301 and continue to carry out.
Step 308: judge module judges that further whether the BLER estimated value close THRESHOLD ESTIMATION value K53 less than one preset second, and whether the BLER estimated value of UE closes time T that THRESHOLD ESTIMATION value K53 kept greater than one second shut-in time threshold T 62 less than second.
If the BLER estimated value less than second close THRESHOLD ESTIMATION value K53 the time T that this state kept greater than the second shut-in time threshold T 62; Think that then the service quality that UE provides is stable, when closed portion receiver branch, still customer satisfaction system service can be provided; Otherwise just think service that UE provides and unstable.
The judged result of judge module is if the BLER estimated value is closed THRESHOLD ESTIMATION value K53 less than second, and the BLER estimated value closes time T that THRESHOLD ESTIMATION value K53 kept greater than the second shut-in time threshold T 62 less than second, then changes step 309; Otherwise after through the preset time interval, return step 301 and continue to carry out.
The control module of step 309:UE is according to the judged result of judge module, further under the prerequisite that guarantees service quality, and the receiver branch that the shutdown signal quality of reception is relatively poor, and after the preset time interval, return step 301 and continue to carry out.
Flow process with the automatic configuring receiver of UE under the above-mentioned MBMS scene is the same, and the user of UE also can close the setting of automatic configuring receiver at any time.If the user has closed the setting of automatic configuration, the UE under the then non-MBMS scene can not carry out the automatic of receiver and dispose.
In addition, also can be only under the non-MBMS scene judge whether that according to signal receiving quality indexs such as BLER estimated values needs close or open the branch of UE receiver, and need not carry out the judgement of the time of the UE institute inhibit signal quality of reception.Same; Under the MBMS scene; Also can not only judge, but also on the basis of judging the BLER estimated value, carry out the judgement whether part receiver branch was closed or opened to needs according to the time that signal receiving quality kept according to the BLER estimated value.
Being example with double-receiver UE below, having provided the control implementation algorithm embodiment of UE under MBMS scene and non-MBMS scene respectively, wherein also is the representative of received signal quality with BLER.Therefore, on thinking, BLER also can be the concrete manifestation form of received signal quality such as SIR, just control algolithm according to concrete select to have a little change, those skilled in the art can realize according to prior art fully.
Control implementation algorithm under the MBMS scene
If (CRC failure)
{
Estimate that BLER=(1-α) * estimates BLER+ α
}
Else
{
Estimate that BLER=(1-α) * estimates BLER
}
If (estimation BLER K51 and UE are in the double-receiver pattern)
{
(for example at first closing performance the poorest also is the poorest the connecing of signal receiving quality according to specified criteria
Receipts machine branch is perhaps selected according to the user) close a receiver branch, get into the single-receiver pattern
}
If (estimate BLER>K52 and UE be in the single-receiver pattern)
{
Open the receiver branch that closes, be transformed into the double-receiver pattern
}
Wherein, the time signal quality thresholding (empirical value that band is redundant) that K51, K52 represent, what α represented is correction factor.
[the control implementation algorithm under the non-MBMS scene]:
If (CRC failure)
{
Estimate that BLER=(1-α) * estimates BLER+ α
}
Else
{
Estimate that BLER=(1-α) * estimates BLER
}
If (estimation BLER K51 and UE are in the double-receiver pattern)
{
If (timer>T61)
{
According to specified criteria (for example at first close the poorest receiver branch of performance or according to
The user selects) close a receiver branch, get into the single-receiver pattern
The timer zero clearing
}
}
Else
{
The timer zero clearing
}
If (estimate BLER>K52 and UE be in the single-receiver pattern)
{
Open the receiver branch that closes, be transformed into the double-receiver pattern
}
Wherein, K51, K52 are signal quality thresholding (empirical value that band is redundant), and α is a correction factor, and T61 is that timer zero clearing last time is to the duration that judgement takes place.
No matter the automatic configuring receiver of user's active arrangement receiver or UE all is under the prerequisite that does not influence UE service quality, to realize reducing the UE energy consumption through the configuration UE receiver, and and then reaches and prolong the UE purpose of service time.But no matter adopt which kind of mode configuring receiver, the user Once you begin uses this function, and UE will send the message relevant with entitlement to system side.After having only system side to make sure answer, the user could the normal service of using this function to bring.Referring to Fig. 4, the authorizing procedure of UE configuring receiver service comprises the steps:
Step 401:UE lateral system side is sent request entitlement message, and request has the right to use of configuration UE receiver service.The information such as ID that contain UE in the authentication message of this request service.
Step 402: system side corresponding authentication server unit carries out authentication operations according to the information such as ID of UE to the request of UE side, judges whether this UE has the right to use of configuring receiver service.If authentication is passed through, then return authentication through message to the UE side, change step 403; Otherwise system side is just returned failed authentication message to the UE side, changes step 404.
Step 403:UE side has just had the right to use of this service of configuration UE receiver receiving authentication that system side returns through after the message., needs carry out appropriate configurations when carrying out the receiver configuration.
Step 404: because the authentication operations of system side do not pass through, so the UE side just can not obtain the right to use of this service of configuration UE receiver, can not be configured the UE receiver.
