Description

A kind of method that disposes based on the transformat of UE capability

Technical field

The present invention relates to wireless telecommunication system, be specifically related to a kind of method that disposes based on the transformat (TF, Transport Format) of subscriber equipment (UE, User Equipment) ability in the 3-G (Generation Three mobile communication system).

Background technology

3-G (Generation Three mobile communication system) is the advanced mobile radio communication that can support high-speed mobile environment, voice and multiple business such as data and multimedia are provided.Data are to be decided by the professional transformat of being built on the transmission channel in the transmission rate of eating dishes without rice or wine, and high level can be according to the actual conditions of business to the real-time configuring transmission format of business.

Transformat is the configuration to transmission channel.Transformat can change by frame on the dedicated transmission channel, in fact constitutes a kind of Radio Resource control ability based on the quick variation of transformat.There is a transformat associated therewith in transmission channel to fixed rate or slow variable Rate.And, need TFS Transport Format Sets (TFS, Transport Format Set) define the mode of information exchange between media interviews controls (MAC) and layer one (L1) to the transmission channel of fast variable Rate.Promptly, need to specify each transformat in this transmission channel format set to each transmission channel.TFS is one group of transformat, and the MAC layer can be selected a suitable transformat according to the momentary rate of information source from TFS on each Transmission Time Interval (TTI, TransmissionTime Interval) time basis.

Transformat is made up of dynamic part, semi-static part two parts.The dynamic part of transformat comprises the size of transmission block size and transport block set, and so-called this two parts content that dynamically is meant can change at different TTI, and dynamic part has formed the momentary rate of transmission channel in other words.Semi-static part comprises the bit number of Transmission Time Interval, channel coding schemes and code rate, static rate match parameter, CRC (CRC, Cyclic Redundancy Check).It is semi-static that its content does not just become with TTI once configuration for dynamically, even need change, and also can only be through reconfiguring behind the high-level consultation.In a TFS, the semi-static part of each transformat is identical.Therefore MAC to the selection of transformat, is actually the selection to the dynamic part of transformat on each TTI basis.

In 3-G (Generation Three mobile communication system); Is The more the better for the configuration of transformat from the angle of transfer of data; The transformat number is many more on the other hand, and is high more to the Capability Requirement of UE, so a kind of like this demand just occurred: under the condition that satisfies the UE ability; Dispose transformat as much as possible, make the transformat that has to have more excellent data transmission performance simultaneously.

For different terminal producer, the ability that its UE can support for different business is also different, and maximum TF number is exactly a kind of in the UE ability, refers to the maximum TF number of all transmission channels that UE can support.Therefore because the restriction of UE ability; Transformat to the high level configuration has certain limitation; When the TF of user's transmission channel number summation surpasses the TF number of UE support; How coming the transformat of configure transport channel to make it can satisfy the UE ability, can control Radio Resource again more excellently, is exactly research contents of the present invention.

Summary of the invention

The technical problem that the present invention will solve provides a kind of method that disposes based on the transformat of UE capability; When selecting deletion and surpass the TF of UE ability; In conjunction with priority with reduce the method that degree of scatter can be joined, not only from the primary demand of the angle guaranteed service of service class property, and when selecting the TF that needs deletion; Considered degree of scatter; Feasible transmission channel to there being TF to be reduced can have more continuous transfer of data as far as possible, can under the situation that satisfies user capability and primary demand, have more excellent data transmission performance.

In order to address the above problem, the invention provides a kind of method that disposes based on the transformat of UE capability, a kind of method that disposes based on the transformat of UE capability may further comprise the steps:

(1) obtain the maximum support of the transformat number that UE reports, and the sum of the transformat on current all transmission channels of user;

(2) more said transformat sum and the maximum number of supporting of said transformat;

(3), then ask for the reservation collection in all transformats of this user if transformat sum surpasses the maximum number of supporting of said transformat;

(4) reduce according to the configurability of transmission channel priority and reduction degree of scatter removing in the residue transformat that keeps beyond the collection;

Further, method of the present invention, wherein, said reservation collection is the set that can not need be remained by deletion;

Further, method of the present invention wherein, in the said step (3), is asked for the reservation collection in all transformats of this user, may further comprise the steps:

(3a) all transformats of all conversation class transmission channels being increased to said reservation concentrates;

(3b) the basic transformat of all non-conversation class transmission channels being increased to said reservation concentrates;

Further, method of the present invention, wherein, the basic transformat of said non-conversation class transmission channel comprises: the transformat of empty bag, the transformat that guarantees the low volume data instantaneous transmission and the transformat of peak transfer rate;

Method of the present invention; Wherein, Said step further comprises in (3): satisfy the UE ability if the transformat sum, then shows current transformat configuration above the maximum number of supporting of said transformat, transformat is not reduced; Directly export current all transformats as a result of this moment, and flow process finishes;

Further, method of the present invention, wherein, said step (4) may further comprise the steps:

(4a) transmission channel is according to priority begun ordering from low to high, promptly transmission channel priority is low more, and its processing priority is high more; If transmission channel priority is identical, then sort according to the transformat number, the transmission channel that the transformat number is more, its processing priority is high more; If transmission channel priority is identical and transmission channel on the transformat number also identical, then sort according to transmission channel identification number size again, wherein the transmission channel identification number is more little, its processing priority is high more; The highest transmission channel of selected processing priority begins to handle;

(4b) selected transmission channel is searched from ascending beginning of transformat; To not keeping collection and preceding Min{K; J} the transformat of all deleting sign is masked as " deletion ", and wherein, K is the dispersion factor when reducing transformat; J is the transformat number before this transformat on the transmission channel, and Min representes to get minimum value; If this transmission channel has not had to indicate the transformat of " deletion ", then execution in step (4d);

(4c) calculate the maximum number of support purpose difference that transformat sum and UE on current all transmission channels of said user reports transformat; If difference equals to have the transformat number of " deletion " sign; Expression no longer exceeds the maximum number of supporting of transformat through the transformat sum after reducing this moment; UE ability, then execution in step (4e) are satisfied in current transformat configuration; If difference is greater than the transformat number that " deletion " sign is arranged, execution in step (4d) continues next round and reduces;

(4d) whether transmission channel circulates and finishes, if do not finish, handles comparing current transmission channel processing priority time high next transmission channel, goes to step (4b); If finish, show that deletable transformat all also can't be satisfied the UE Capability Requirement after the deletion, then failure is handled in output, and flow process finishes;

(4e) do not have in all transformats of this user the sign " deletion " transformat, be the output result;

Further, method of the present invention wherein, in the step (4b), when K is zero, is deletion continuously when deleting a plurality of transformat.

Adopt the method for the invention, compared with prior art, the transmission channel of lower priority requires relatively low to transformat; When user's transformat sum surpasses the UE ability, can rationally reduce (i.e. deletion), the transfer of data demand of protection high priority transfer channel to the transformat of the transmission channel of low priority; Considered degree of scatter simultaneously, feasible transmission channel to there being TF to be reduced can have more continuous transfer of data as far as possible; The method realizes easy, does not need extra control messages auxiliary, and also not relying on certain business must exist; TF to the low priority transmission channel rationally deletes; Also just protect the transfer of data demand of high priority transfer channel so conversely, made under the situation that satisfies UE ability and basic transmission demand, can improve user's susceptibility better.

Embodiment

The present invention is in order to solve the drawback that conventional solution exists; Further set forth a kind of method that disposes based on the transformat of UE capability of the present invention through following specific embodiment; Below embodiment is described in detail, but not as to qualification of the present invention.

As shown in Figure 1, be the method flow sketch map of the embodiment of the invention.May further comprise the steps:

Step 100, flow startup;

Step 101 is obtained UE and is reported the maximum of TF to support number;

Step 102, the TF configuration sum on current all transmission channels of statistics of user's;

Step 103, the maximum transport format number that relatively user's transformat is total and the UE ability is supported, if the transformat sum surpasses the maximum number of UE ability support, then execution in step 104; Otherwise, execution in step 107;

Step 104, initialization keep collection for empty, begin to handle from article one transmission channel, will be to TF all in the conversation class transmission channel, and basic transformat in the transmission channel of non-conversation class is increased to keep concentrates;

Step 105, the method sign of pressing the transmission channel priority order and disperseing to reduce is not keeping collection and preceding Min{K, and the transformat of the individual all not deletion signs of J} is masked as " deletion ";

Step 106; The TF that newly-increased " deletion " indicated during this was taken turns; Show that this TF will be rejected, and the TF sum on current all transmission channels of user is deducted 1, and the TF sum that will deduct after 1 be total as the TF of next round when output; Execution in step 103 then, make comparisons with the TF maximum number of UE ability again;

Step 107, export do not have in current all transformats of this user the sign " deletion " TF as a result of;

Step 108; Flow process finishes.

Above-mentioned steps 105 described priority orders and the processing mode of disperse reducing specifically describe as shown in Figure 2ly, are the transmission channel processing priority of the embodiment of the invention sketch map that sorts, and may further comprise the steps:

Step 200, flow process begins;

Step 201 according to priority begins ordering from low to high to transmission channel, and promptly transmission channel priority is low more, and its processing priority is high more; Earlier the high transmission channel of processing priority is handled;

Step 202 judges whether the priority of transmission channel is identical, if identical, then execution in step 203; Otherwise, execution in step 206;

Step 203 detects the TF number in the transmission channel of said equal priority, if the TF number is also identical, then execution in step 204; If inequality, then execution in step 205;

Step 204, the TF number is also identical on the identical and transmission channel of transmission channel priority, then sorts according to transmission channel identification number size again, and wherein, the transmission channel identification number is more little, and its processing priority is high more, more first processing; The transmission channel identification number is big more, and its processing priority is low more, reprocessing more; Execution in step 206 then;

Step 205, transmission channel priority identical but on the transmission channel TF number inequality, then sort according to the TF number, the transmission channel that the TF number is more, its processing priority is high more; The transmission channel that the TF number is few more, its processing priority is low more; Execution in step 206 then;

Step 206, the transmission channel after the output ordering; The selected high transmission channel of processing priority is handled earlier.

As shown in Figure 3, be specific embodiment of the invention sketch map.May further comprise the steps:

Step 300, flow process begins;

Step 301 is obtained the maximum support of the TF number that UE reports, and the sum of the TF on current all transmission channels of user;

Step 302, the maximum transport format number that relatively user's transformat is total and the UE ability is supported, if the transformat sum surpasses the maximum number of UE ability support, then execution in step 303; Otherwise, execution in step 311;

Step 303, a newly-built set is made as and keeps collection and empty, and begins statistics from article one signaling corresponding transmission channel, handles the transmission channel sequence number and is initialized as 0;

Step 304, whether the detected transmission channel type is conversation class, if then execution in step 305, otherwise, execution in step 306;

Step 305, to the conversation class transmission channel, the TF that it is all is increased to keep and concentrates; Execution in step 307;

Step 306 to the transmission channel of non-conversation class, is increased to reservation with basic transformat and concentrates; Execution in step 307;

Step 307 detects all transmission channels that whether circulated; If, collection that output is withed a hook at the end, execution in step 309; Otherwise, execution in step 308;

Step 308 continues to handle next transmission channel; Execution in step 304;

The difference (Tf_Diff) of the maximum TF number that step 309, the TF sum that calculates this user and UE ability are supported;

Whether step 310 detects difference (Tf_Diff) greater than zero; If greater than zero, represent that this user's TF sum exceeds the maximum TF number that the UE ability is supported, need reduce execution in step 312 to TF; If be not more than zero, represent that then this user's TF sum does not exceed the maximum TF number that the UE ability is supported, need not reduce execution in step 311 to TF;

Step 311 is exported all TF that current each transmission channel is not designated " deletion ", process ends;

Step 312 sorts by transmission channel priority to transmission channel from low to high, begins to handle from the transmission channel of lowest priority; The transmission channel identical to priority, it is higher that the many processing priority of transmission channel TF number then are set; If priority is identical and the TF number is also identical, the processing priority that then the transmission channel identification number is little is higher;

Step 313, transformat begins to handle from the TF of minimum;

Step 314 judges whether this TF is not keeping collection, and preceding Min (K, J) individual all not deletion signs; If do not keeping collection, and all do not have " deletion " sign, then execution in step 315; Otherwise, execution in step 317;

Step 315 indicates that this TF state is " deletion ", and execution in step 316;

Step 316, the Tf_Diff value deducts 1, execution in step 310;

Step 317, whether the TF that detects this transmission channel has circulated and has finished, if finish, then execution in step 319; Otherwise, execution in step 318;

Step 318 is handled next TF in this transmission channel, execution in step 314;

Step 319, all transmission channels that whether circulated, if do not have, then execution in step 320; Otherwise, execution in step 321;

Step 320 is handled next bar transmission channel, execution in step 313;

Step 321 is handled failure, finishes.

Based on Fig. 3, provide an object lesson below:

Suppose that the user has 2 PS business (interactive class), a speech business, the UE ability can support that the maximum number of TF is 26, and the TFS of its each transmission channel disposes like table 1:

Table 1 user's each transmission channel priority and TFS configuration

Wherein, the relation of transmission channel priority is respectively: A＞B＞C＞D, promptly the PS1 processing priority is the highest, handles at first.TFij representes j+1 transformat of i bar transmission channel, and the selection owing to transformat is actually the selection to the dynamic part of transformat; So omit other part; The TFij here refers to transmission block number (TBNum, Transport BlockNumber) and the transmission block size (TBSize of transformat; Transport Block Size), its TF is configured from small to large to every transmission channel.It is 1 that this example is got K.

The execution flow process of its configuration TF is:

1) obtain that TF that UE reports is maximum to support that number is 26, and the TF on current all transmission channels of user adds up to 2+5+9+6+5+2=29;

2) obvious, user's TF sum is reduced so next need carry out TF greater than the maximum TF number in the UE ability at this moment;

3) a newly-built set is made as the reservation collection and empties, and begins statistics from article one signaling corresponding transmission channel;

4) by mentioned above principle, first three bar transmission channel is non-session service, its basic transformat is increased to keep to collect be: { TF10, TF11, TF20, TF21, TF24, TF30, TF31, TF38}; Article four, transmission channel is a session service, its all TF all is increased to keep concentrates;

5) so after four transmission circulations finished, the reservation collection of output was: { TF10, TF11, TF20, TF21, TF24, TF30, TF31, TF38, TF40, TF41, TF42, TF43, TF44, TF45, TF50, TF51, TF52, TF53, TF54, TF60, TF61};

6) in this example, the TF number that statistics needs to reduce is Tf_Diff=29-26=3;

7), begin to handle from article one transmission channel to the transmission channel after the ordering; The transmission channel of lowest priority is the PS1 corresponding transmission channel;

8) in the PS1 corresponding transmission channel, begin to judge, because TF20 and TF21 all concentrate in reservation from first TF (TF20); Can not delete; So continue down to arrive TF22 totally 2 TF before the TF22, preceding 1 (min{1; 2}) individual TF (being TF21) does not have " deletion " sign, so sign TF22 is " deletion ";

9) equal 2 after this moment, Tf_Diff deducted 1,, explain that this moment, total TF number can't satisfy the UE ability, continue the reduction of next round, down search deletable TF still greater than 0; The existing deletion sign of the previous TF of TF23, thus continue down to look for, and TF24 concentrates in reservation, so the TF of this transmission channel has searched to finish and has been much to seek the TF of new indicated deletion;

10) continuing to search at the lower transmission channel of next priority, is the PS2 corresponding transmission channel at this moment, as stated above, in like manner can obtain indicating the TF:TF32 of " deletion ";

11) more current again TF sum and UE ability equal 1 after Tf_Diff deducts 1, still greater than 0, also need search a deletable TF, in like manner can get, and TF34 can indicate " deletion ";

12) TF of not deletion sign of output, its output result sees table 2:

The TFS (each transmission channel priority is not simultaneously) of each transmission channel after table 2 is reduced

Moreover; If the priority of PS2, PS3 is identical, and when all being lowest priority, because the TF number of PS2 is more than PS1; So PS2 the processing priority of corresponding transmission channel the highest; Through behind the algorithm of the present invention, the TF of sign " deletion " is TF32, TF34 and TF36, and output result at this moment is:

TF4 3 TF4 4 TF4 5

The TFS of each transmission channel after table 3 is reduced (PS1, when PS2 priority is identical)

Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
