For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Set forth in the following description a lot of details so that fully understand the present invention, implemented but the present invention can also adopt other to be different from alternate manner described here, therefore the present invention is not subject to the restriction of following public specific embodiment.
Just as described in the background section, the RSRP only obtaining according to RS calculated signals in prior art or RSRQ carry out the link monitoring under LTE mobile terminal IDLE state, because the calculating accuracy rate to RSRP or RSRQ is limited, have therefore reduced service success rate.
For the problems referred to above, the invention provides a kind of data processing technique, its RSRP or RSRQ in the current service cell that calculates is less than corresponding threshold value, realize the monitoring of channel quality information by the data of decoding PBCH channel, thereby solve the problem that RSRP or PSRQ signal can not reflect channel-decoding situation, finally improved the service success rate under IDLE state.
Be elaborated below in conjunction with accompanying drawing.
Shown in figure 1, the present embodiment provides a kind of data processing method, comprising:
Step S1, judges the current state of LTE mobile terminal, when in idle condition, and execution step S2;
Step S2, obtains reference signal, and calculates corresponding Reference Signal Received Power or Reference Signal Received Quality;
Step S3, judges whether described Reference Signal Received Power or the reference information quality of reception are less than corresponding threshold value, in the time being less than, and execution step S4;
Step S4, obtains Physical Broadcast Channel signal, and according to described Physical Broadcast Channel signal, obtains channel quality information;
Step S5, according to described channel quality information, adjusts the value of reporting of described Reference Signal Received Power or Reference Signal Received Quality.
The present embodiment is not only according to RSRP corresponding to RS calculated signals or RSRQ, and in the time that RSRP or RSRQ are less than corresponding threshold value, further according to PBCH calculated signals channel quality information, thereby can adjust described RSRP or RSRQ according to channel quality information, finally carry out community switching or system switching or fall net and process according to the RSRR after adjusting or RSRQ, thereby having improved the service success rate of LTE mobile terminal under IDEL state.
First perform step S1, judge the current state of LTE mobile terminal.
Described LTE mobile terminal can be the arbitrary mobile terminal that adopts LTE communication system to communicate, as: mobile phone, notebook, panel computer etc.
State in described LTE mobile terminal is divided into idle condition and connection status, wherein: idle condition is exactly in paging listening state, and now and between network, do not set up any signaling and business relations.
Concrete judge that the process of LTE mobile terminal current state knows for those skilled in the art, do not repeat them here.
Learn that when judgement LTE mobile terminal is current during in connection status, finish; When judgement learns that LTE mobile terminal is current during in idle condition, need to continue execution step S2, obtain reference signal, when the LTE agreement before LTE mobile terminal adopts R9 version communicates,, according to RS signal, calculate RSRP corresponding to current service cell; Otherwise, according to RS signal, calculate RSRQ corresponding to current service cell.
Described RSRP receives in bandwidth in system, each RSRE(reference signal resource unit of corresponding cell reference signals on two time slots) linear averaging of received power.Particularly, RSRP=P

Described RSRQ is according to RSRQ=RSRP*N
pRB/ RSSI calculates, wherein, and N

pRB* N
pRB* PathLoss/N
symbol, P
pRBrefer in system receives bandwidth the average transmit power of PRB on two time slots; N
symbolrefer to the OFDM symbolic number on each PRB, by CP(Cyclic Prefix) configuration determine.
It should be noted that, in other embodiments of the invention, can also adopt other modes according to RSRP corresponding to RS calculated signals or RSRQ, it does not limit the scope of the invention.
Then perform step S3, judge whether described Reference Signal Received Power or the reference information quality of reception are less than corresponding threshold value.
In the present embodiment, set in advance threshold value or threshold value corresponding to RSRQ that RSRP is corresponding, in the time that the RSRP calculating or RSRQ are less than corresponding threshold value, think that channel quality may be poor, cannot decode.Particularly, can comprise-80dBm of the span of the threshold value that described RSRP is corresponding～-120dBm, as :-80dBm ,-100dBm or-120dBm; Can comprise-85dB of the span of the threshold value that described RSRQ is corresponding～-105dB, as :-85dB ,-95dB or-105dB, but it does not limit the scope of the invention.
When the RSRP calculating as step S2 or RSRQ are less than corresponding threshold value, continue execution step S4, obtain Physical Broadcast Channel signal.
In the present embodiment, base station can timing send PBCH channel data (being Physical Broadcast Channel signal) to LTE mobile terminal, but only has in the time that the RSRP calculating or RSRQ are less than corresponding threshold value, and LTE mobile terminal just removes to receive described Physical Broadcast Channel signal.
The present embodiment, after obtaining described Physical Broadcast Channel signal, need to, according to described Physical Broadcast Channel signal, obtain channel quality information.Particularly, according to described Physical Broadcast Channel signal, obtaining channel quality information can comprise: described Physical Broadcast Channel signal is decoded, obtain corresponding cyclic redundancy check (CRC) code; According to described cyclic redundancy check (CRC) code, judge whether described channel quality meets decode condition.
The PBCH data that the present embodiment is decoded current in each paging (paging) cycle detection paging data, only by sub-frame decoding PBCH data, its process of obtaining corresponding cyclic redundancy check (CRC) code by decoding is same as the prior art, does not repeat them here.
In first object lesson, judge whether described channel quality meets decode condition and comprise:
Set point number parameter, and the initial value of setting described number of times parameter is a fixed value;
In the time that described cyclic redundancy check (CRC) code is correct, make the value of described number of times parameter increase m and be not more than described fixed value; In the time of described cyclic redundancy check (CRC) code mistake, make the value of described number of times parameter reduce n, m is more than or equal to 0 integer, and n is more than or equal to 1 integer;
In the time that the value of described number of times parameter is less than preset value, described channel quality does not meet decode condition.
Gathering way of described number of times parameter can be greater than, be less than or equal to the speed that reduces of described number of times parameter, and described m can be greater than, be less than or equal to n.
Preferably, described m is less than n, thereby in the time that channel quality is poor, can carry out as early as possible subsequent treatment.As: when the 1st, 8 and 12 cyclic redundancy check (CRC) code correct, and 2nd ~ 7,9 ~ 11 and 13 ~ 17 cyclic redundancy check (CRC) code mistakes, described m is 1, described n is 2, described preset value is 0, described fixed value is 24 o'clock, the initial value of first set point number parameter t is 24; Because first cyclic redundancy check (CRC) code is correct, number of times parameter t should add 1 operation, but is greater than 24 because number of times parameter t becomes 25 after adding 1, and therefore now the value of number of times parameter t is still 24; Due to the second cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 22; Due to the 3rd cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 20; ..; Due to the 7th cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 12; Because the 8th cyclic redundancy check (CRC) code is correct, therefore number of times parameter t need to add 1 and becomes 13; Due to the 9th cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 11; Due to the tenth cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 9; Due to the 11 cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 7; Because the 12 cyclic redundancy check (CRC) code is correct, therefore number of times parameter t need to add 1 and becomes 8; Due to the 13 cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 6; Due to the 16 cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become 0; Due to the 17 cyclic redundancy check (CRC) code mistake, therefore number of times parameter t need to subtract 2 and become-2, and now-2 are less than preset value 0, and therefore described channel quality does not meet decode condition, needs to continue execution step S5.
In second object lesson, judge whether described channel quality meets decode condition and comprise: in the time that the continuous wrong number of described cyclic redundancy check (CRC) code is greater than set point, described channel quality does not meet decode condition.The span of set point described in the present embodiment can be more than or equal to 3, and, as long as the continuous wrong number of described cyclic redundancy check (CRC) code is more than or equal to 3, described channel quality does not meet decode condition.
In the 3rd object lesson, judge whether described channel quality meets decode condition and comprise: in the time that the wrong number of described cyclic redundancy check (CRC) code accumulative total is greater than set point, described channel quality does not meet decode condition.The span of set point described in the present embodiment can be more than or equal to 3, and, as long as the wrong number of described cyclic redundancy check (CRC) code accumulative total is more than or equal to 3, described channel quality does not meet decode condition.
The span of the described set point in above-mentioned second object lesson and the 3rd object lesson can be different.
In the time that described channel quality does not meet decode condition, continue execution step S5, adjust the value of reporting of described Reference Signal Received Power or Reference Signal Received Quality.
The present embodiment can, in the time that described channel quality does not meet decode condition, be adjusted into corresponding minimum value by described Reference Signal Received Power or Reference Signal Received Quality.Particularly, the minimum value that described Reference Signal Received Power is corresponding can be-150dBm; The minimum value that described Reference Signal Received Quality is corresponding can be-120dB.
If: the RSRP calculating in step S2 is-100dBm, learn that by step S3 and step S4 current channel quality does not meet decode condition, therefore will be by the RSRP calculating by-be adjusted into-150dBm of 100dBm in step S5.
And for example: the RSRQ calculating in step S2 is-95dB, learns that by step S3 and step S4 current channel quality does not meet decode condition, therefore will be by the RSRQ calculating by-be adjusted into-120dB of 95dB in step S5.
In addition, the present embodiment is after being adjusted into corresponding minimum value by described Reference Signal Received Power or Reference Signal Received Quality, can also comprise: described Reference Signal Received Power or Reference Signal Received Quality after adjusting are sent to radio resource control layer, and described radio resource control layer carries out community switching or system is switched or falls net and process.Particularly, send the measurement report of the RSRQ after RSRP or the adjustment comprising after adjustment to radio resource control layer, because the numerical value of RSRP in measurement report or RSRQ is smaller, therefore radio resource control layer can make the LTE service terminal in the current Serving cell in not realizing data decode carry out community switching or system switching or fall net and process, thereby make the LTE mobile terminal can be relatively good can realize in the Serving cell of data decode in channel service quality at IDEL state, finally paging can not occur does not have situation about decode in time, improve service success rate.
Further, owing to only passing through sub-frame decoding PBCH data in a paging cycle, therefore in a paging cycle, only also need to carry out the judgement of a channel quality, thereby can greatly save electric energy.
