Embodiment
As stated in the Background Art; time in prior art owing to carrying out organizational scheduling to system information block; only identical for the system information block repetition period is placed in a SI; and not each SI is not crossed the border protection; therefore may cause the content in a SI too much and cannot send, the system information block that must obtain cannot be obtained very smoothly, waste internal memory and easily because the excessive memory overwriting that causes of individual system block of information; PER encodes unsuccessfully, and failed problem is set up in community.
For this reason, the embodiment of the present application one proposes a kind of system information transmission method, is applied in LTE system, in order to solve the problems of the prior art, as shown in Figure 2, specifically comprises the following steps:
Step 201, is distributed in each hicap block of information in different system information SI respectively and transmits;
In concrete scene, described hicap block of information comprises: SIB1, SIB5, SIB6, SIB7; Described low capacity system information block comprises: SIB2, SIB3, SIB4; Below be specifically described for system information block SIB1-SIB7
Wherein, before SIB1 coding, shared PDU size is 1174 bytes, and after coding, shared PDU size is 90 bytes;
Before SIB2 coding, shared PDU size is 636 bytes, and after coding, shared PDU size is 70 bytes;
Before SIB3 coding, shared PDU size is 513 bytes, and after coding, shared PDU size is 18 bytes;
Before SIB4 coding, shared PDU size is 828 bytes, and after coding, shared PDU size is 63 bytes;
Before SIB5 coding, shared PDU size is 2104 bytes, and after coding, shared PDU size is 285 bytes;
SIB, before 6 codings, shared PDU size is 1152 bytes, and after coding, shared PDU size is 247 bytes;
Before SIB7 coding, shared PDU size is 5320 bytes, and after coding, shared PDU size is 732 bytes;
PDU after visible coding take up space than coding before PDU little, wherein can as required by system information block SIB1, SIB4, SIB5, SIB6, SIB7 are set to hicap block of information; Accordingly, other system information block is just set to low capacity block of information, the size of threshold value can encode after PDU take up space that to be no more than the size that in the protocol stack of LTE system wireless access side, Layer2 limits be principle, its threshold value can adjust flexibly based on needs, no longer carries out superfluous chatting at this.
For SIB1-SIB7, hicap block of information wherein has SIB1, SIB5, SIB6, SIB7, if by its scheme conventionally, identical for the repetition period being all distributed in a SI is transmitted, such as may SIB5 and the SIB6 repetition period identical, this will cause the content in a SI too much, cannot issue, and also can not obtain the system information block of needs in time, therefore respectively hicap block of information is distributed in different SI and transmit.
Step 202, is distributed in the system information block SIB2 in low capacity system information block separately in a SI and transmits; Wherein, described hicap block of information is the system information block that system information block size is greater than predetermined threshold value, and described low capacity system information block is the system information block that system information block size is less than predetermined threshold value;
Although SIB2 is smaller, SIB2 is the necessary system information block of system, therefore in the case, also SIB2 can be distributed in separately in a SI and transmit.
Step 203, determines the number of other low capacity system information blocks beyond described SIB2 and the repetition period of each other low capacity system information blocks described;
For SIB1-SIB7, in low capacity system information block except SIB2, also has SIB3, SIB4, wherein SIB3 and SIB4 is smaller, also can not cross the border even if SIB3 and SIB4 is distributed in same SI to carry out transmitting, therefore whether identically can to distribute based on its repetition period, just need the repetition period of the number of other low capacity system information blocks determined beyond SIB2 and each other low capacity system information blocks described for this reason.
Step 204, if there is multiple low capacity system information block, transmits for low capacity system information block that the repetition period is identical is distributed in same SI, transmits for low capacity system information block that the repetition period is different is distributed in different SI.
For SIB1-SIB7, if the repetition period of SIB3 with SIB4 is identical, SIB3 and SIB4 is distributed in same SI and transmits, if different, then transmit for it is distributed in different SI separately, in addition, also likely only there is SIB3, or only there is SIB4, then the system information block only deposited is distributed in an independent SI and transmits.
Wherein, above-mentioned step 201 and step 202 and step 204 are (certainly; step 203 determines it is before the step 204) be only used to be convenient in the application describe and arrange; under the prerequisite not changing the present application point, to its any change carrying out precedence also in the protection range of the application.
And before system information block being distributed in SI transmission, also comprise:
Coded treatment is carried out to described system information block; Size after same system information block encoding is less than the size before coding.
For SIB1-7, each system information block size is in encoded less than the size before coding, and such as, before SIB1 coding, shared PDU size is 1174 bytes, and after coding, shared PDU size is 90 bytes.
And before system information is encoded, also comprise:
Be that described system information block reconfigures buffering area according to the size before described system information block forecast; The buffer size reconfigured is greater than the buffer size before reconfiguring; For the SI internal memory of each system information block configuration formed objects; Described SI memory size is no more than default threshold value.
Concrete, be still SIB1-SIB7 with system information block for example is described, arranging size because the buffering area to before each system information block forecast of the prior art is unified is 800 bytes, and in fact SIB1, SIB5-SIB7 has exceeded the size of 800 bytes before encoding, what therefore need setting buffers is larger, with reference to SIB1-SIB7, wherein, except SIB7 (is 5320 bytes, size much larger than buffering area shared by other system block of information) beyond other system information block in maximum close to 2000 bytes, and different buffer size is set based on different system information blocks, involved amendment is too many, and consider that shared by SIB1-SIB6, the size of buffering area is less than 2000 bytes, scope is smaller, therefore for SIB1-SIB6, buffer size before being encoded by SIB1-SIB6 is set to 2000 bytes, specially a new buffering area is set for SIB7, and consider and generally can not configure so large SIB7, if and shared buffering area is greater than 5000 before coding, also (L2 is the restriction after encoding to each SI PDU to be decidedly superior to L2 after coding, size is 2216bit, i.e. 277 bytes) restriction, so the buffer size before being encoded by SIB7 is set to 5000 bytes.
And the setting of SI (SystemInformation, system information) then can limit, specifically can reduce, under concrete scene, SI can be changed to 2216bit (i.e. 277 bytes) from 2000 bytes of the prior art.Can realize on the whole thus saving internal memory, certainly can also specifically to arrange the memory size of this SI as required, no longer carry out going to live in the household of one's in-laws on getting married at this and chat.
And after redistribute buffering area and SI internal memory for system information block, can judge whether the data length before described hicap information block encoding exceedes preset value;
If the determination result is YES, brachymemma process is carried out to described hicap block of information.
For SIB1-7, its Small And Medium Capacity system information block is SIB2, SIB3, SIB4, data length before these three low capacity system information block forecast known can exceed preset value scarcely, therefore can not need to judge, only need to judge hicap block of information, to save system resource.
Concrete, such as, data length before certain system information block forecast exceedes preset value, such as more than 5000 bytes, (preset value can be arranged based on needs, be not limited to this value), in the case, mean that the content in this system information block is too many, even if encode, also the size that L2 limits can be exceeded, cannot be sent out down, be described for SIB7 at this, before SIB7 coding, shared buffer size is 5320, be greater than 5000, owing to being greater than 5000, to mean that SIB7 content is filled out too many, PDU has encoded rear affirmative also can more than the restriction of L2, broadcast is not sent out not go out yet, therefore brachymemma process can be carried out to this SIB7.
And concrete, described brachymemma process is carried out to described hicap block of information, be specially:
If comprise multiple different system frequency in described hicap block of information, then the different system frequency choosing predetermined number by brachymemma function is encoded; Wherein, described predetermined number is less than or equal to the frequency points of described hicap block of information.
Concrete, for SIB1-7, comprise UTRA frequency in SIB6, the Geran frequency of system is comprised in SIB7, therefore SIB7 is eligible, for SIB7, brachymemma process is described for this reason, first determine Geran (the GSM EDGE Radio Access Network of SIB7, GSM EDGE Radio Access Network) frequency points, can 6 be greater than, and in fact, through adding up SIB7, it puts 6 GERAN frequencies at full configuration, by display mode statistics (namely each frequency mode follow-up is listed in display) maximum after coding SI, again after PDU coding, SIB7 just can be no more than the restriction of L2, therefore front 6 the Geran frequencies can choosing SIB7 are encoded.
In order to be described the application further, the embodiment of the present application two proposes a kind of system information transmission method based under concrete application scenarios, comprising:
In existing code, 800 bytes are defined as the buffer size before each SIB coding, after coding, in each SI, save as 2000 bytes; And to system information block (SIB1-SIB7) be optimized need current system information block is added up, each SIB is filled according to the mode of full configuration in agreement, as shown in table 1, be SIB1-SIB7 coding before and coding after statistics.
Statistics before table 1.SIB1-SIB7 coding and after coding
| PDU size before coding | PDU size after coding | |
| SystemInformationBlockType1 | 8854/1174 | 688/90 |
| SystemInformationBlockType2 | 636 | 70 |
| SystemInformationBlockType3 | 513 | 18 |
| SystemInformationBlockType4 | 828 | 63 |
| SystemInformationBlockType5 | 4024/1779 | 565/213 |
| SystemInformationBlockType5(2) | 2104 | 285 |
| SystemInformationBlockType6 | 1152 | 247 |
| SystemInformationBlockType7 | 5320 | 732 |
Wherein, there is "/" in SIB1 and SIB5 in table 1, and its implication is the full configuration value that value before "/" represents agreement, and the value after "/" then represents the theoretical full configuration value of existing codes implement.SIB5 theoretical value has two statistical values as can be seen from Table 1, and one of them carries out adding up according to 3 frequencies (wherein, each frequency 16 communities); Another is then added up according to 8 frequencies (each frequency is 6 cell configuration).
Can know according to the statistics before coding in table 1, in prior art SIB encode that front buffering area 800 byte arranges too little, need to expand; The ratio that front buffering area should arrange of encoding is greatly existing, encodes unsuccessfully to prevent PER; Before SIB7 coding, shared buffering area is 5320 to the maximum in addition, and other SIB are relatively little, SIB7 should be defined separately, for SIB7 configures separately a new front buffering area of coding.
For this situation, consider that in existing code, SIB1-SIB7 is defined in a data structure; If each SIB defines different buffer size, larger to code change; And can know according to table 1, only having SIB7 to belong to, needs are additionally configured separately, for this reason, by unified be greater than PDU to encode maximum SIB to the buffer definitions of SIB1-SIB6, and more than the restriction of L2, therefore can not be set to 2000 by unified for the buffer size before system information block forecast each in SIB1-SIB6 after coding; And for SIB7, if consider that front buffering area of encoding is greater than 5000, after coding, being also decidedly superior to L2 restriction, therefore newly-increased data structure, front buffering area of being encoded by SIB7 is set to 5000.
In follow-up processing procedure, as shown in Figure 3, to the judgement of whether crossing the border to all system information blocks, then can will become stored in the corresponding overall situation, also be the data structure of its configuration.In addition, because SIB7 is large especially, even if therefore the SIB7 after coding is placed on separately in a SI, also possibly more than the restriction of L2; For this reason, shown in Fig. 4, judgement is crossed the border (certainly to the buffering area after coding shared by SIB7, also can to cross the border to all system information blocks judgement, be described for SIB7 at this), if be greater than 5000, exit process (illustrate that SIB7 content is filled out too many, PDU has encoded rear affirmative also can more than the restriction of L2, and broadcast cannot send).And SIB7 more special (important), if exit processing procedure to it, some problems can be caused, for this reason, exceeded the restriction of L2 after judging SIB7 coding after, SIB7 be carried out brachymemma process, and then send.Concrete, judge SIB7 carry out PDU encoded after length long, and Geran frequency points is greater than 6, and owing to passing through, SIB7 is added up, it puts 6 GERAN frequencies at full configuration, by display mode statistics (namely each frequency mode follow-up is listed in display) maximum after coding SI, again after PDU coding, SIB7 just can be no more than the restriction of L2, if therefore SIB7 is excessive, brachymemma function can be called to SIB7 process, by SIB7 brachymemma, concrete, fixingly Geran frequency points is set to 6 encodes.
And can know according to the statistics of each SIB after coding in table 1: SIB2, SIB3 and SIB4 are smaller after carrying out PDU coding, although and SIB1 and SIB6 is larger, but according to present configuration can not more than L2 (L2 be each SI PDU is encoded after restriction, size is 2216bit, i.e. 277 bytes) restriction.SIB5 likely more than the restriction of L2, but can have the amendment optimized for PCI in current code, and therefore SIB5 is also not easy the restriction more than L2.
Wherein, as shown in Figure 5, SIB2 is that UE must obtain system information block, is therefore taken apart separately by SIB2 and is placed in SI; SIB5 and SIB6 is comparatively large, if be placed in a SI with other system block of information, also can cause the restriction more than L2, therefore also take process apart separately; And SIB3 and SIB4 is smaller, so according to agreement, the repetition period of system information block can be judged, if SIB3 and SIB4 is identically just placed in a SI by the repetition period, if difference, take process apart; Due to the system information block that SIB7 is maximum, therefore also take apart separately and to be placed in a SI and (because SIB7 may not exist, therefore can judge it, if SIB7 exists, just independent SIB7 is placed in SI; If there is no, then treatment S IB7 is not needed), with this after carrying out above-mentioned process, according to existing procedure process subsequent process.
Owing to specifying the SIB of identical repetition period according to agreement, be placed in different SI and be fine, therefore can not be overlapping.
And concrete, the maximum number of byte of each SI also needs amendment, and what define in code is 2000 bytes before, does not consider the restriction of L2, is revised as 2216bit in this programme, is also 277 bytes.Thus, the buffering area of MIB, SIB1-SIB6 is increased to 2000SIB7 from 800 and is increased to 5000 from 800.The size of each SI narrows down to 277 from 2000.If base station is set up 12 communities and is increased internal memory newly and be calculated as follows:
7*12* (2000-800)+12* (5000-800)-12*13 (2000-277)=-117588 (byte)
By above-mentioned calculating, can know that the scheme of the application saves 117588 bytes.
For the system information transmission method in the application, key point of the present invention and wish protect point as follows:
By above-described embodiment that the application proposes, result according to the statistics of system information block configures the front buffering area of different codings and unified SI internal memory to different system information blocks, be assigned in different SI internal memories based on system information block, and carry out different process for the situation of different system block of information, make terminal more easily read system information block; The scheduling of system information block is more rigorous, simplifies; Save EMS memory occupation, prevent memory overwriting; Avoiding the community caused due to system information code error time community is set up sets up unsuccessfully, and PER encodes the problem such as unsuccessfully.
