Embodiment
At problems of the prior art, Data Receiving scheme in a kind of brand-new mobile multimedia broadcast system is proposed among the present invention, that is: at first, the program list information that obtains by this sub-district determined and available adjacent sub-district merges the unified program list information that forms, and, for the total program in this sub-district and available adjacent sub-district, preserve this cell channel parameter and the available adjacent cell channel parameter of this total program correspondence in the unified program list information simultaneously; Then, determine that user selected program is that total program still is the exclusive program in this sub-district or available adjacent sub-district; If total program, then at first utilize this cell channel parameter of this total program correspondence, in this sub-district of this total program correspondence, receive total program data, if fail correct the reception, then utilize the available adjacent cell channel parameter of this total program correspondence, in the available adjacent sub-district of this total program correspondence, receive and should have program data, and in the correct back process ends that receives; If exclusive program, then utilize this sub-district or the available adjacent cell channel parameter of this exclusive program correspondence, in this sub-district of this exclusive program correspondence or available adjacent sub-district, receive this exclusive program data, and in the correct process ends afterwards that receives.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 1 is the flow chart of data receive method embodiment of the present invention.In actual applications, the executive agent of each step in the present embodiment is receiving terminal.As shown in Figure 1, may further comprise the steps:
Step 101: the program list information that obtains by this sub-district determined and available adjacent sub-district merges the unified program list information that forms.
In actual applications, after the receiving terminal start, can at first carry out the described process of this step; But go back the difference that right and wrong are started shooting first according to this start for start first, the specific implementation of the described process of this step is introduced respectively below also with difference.
1) start first:
If start first, receiving terminal can at first carry out the full frequency band search so, with the sub-district of determining that receiving terminal will be resident, it is this sub-district, and available adjacent sub-district and non-available adjacent sub-district, and this sub-district that will get access to and the program list information of available adjacent sub-district merge, and obtains unified program list information, and specific implementation comprises:
At first, the sub-district that the signal quality that searches is best is defined as this sub-district, receives the Common Control Channel of this sub-district, and obtains adjacent cell list, according to received signal quality (SINR) value order from high to low, sorted in each the adjacent sub-district in the adjacent cell list; Afterwards, receive the control channel data and electron service instruction (ESG) information that are in 3 preceding 3 adjacent sub-districts after sorting respectively, and the adjacent sub-district that will successfully receive above-mentioned information is defined as available adjacent sub-district, and the adjacent sub-district that receives above-mentioned information is defined as non-available adjacent sub-district with failing.It is known in this field how obtaining adjacent cell list, repeats no more.
Then, obtain the program list information that carries in the control channel data of this sub-district and available adjacent sub-district and the ESG information respectively, how to be retrieved as known in this field; Afterwards, this sub-district that gets access to and the program list information of available adjacent sub-district are merged, obtain unified program list information.
Need to prove, include programme information and each program channel parameter corresponding here in the program list information of being mentioned simultaneously, as information such as time slot and frequencies.
Obviously, after the program list information to this sub-district and available adjacent sub-district merges, the total program in this sub-district and available adjacent sub-district may appear, for the total program of this class, need in unified program list information, preserve this cell channel parameter and the available adjacent cell channel parameter of this total program correspondence simultaneously so.Illustrate, suppose to comprise A and two programs of B in the program list information of this sub-district, available adjacent sub-district (is convenient statement, suppose to have only an available adjacent sub-district) program list information in comprise B, C, three programs of D, the unified program list information after merging so will comprise A, B, four programs of C, D simultaneously.For A, C, three programs of D, only need the corresponding channel parameter of preserving its former sub-district, place to get final product, but, not only need to preserve its channel parameter in this sub-district for program B, also need to preserve simultaneously its channel parameter in available adjacent sub-district.
2) non-start first
For receiving terminal itself, it is common and do not know whether certain start starts shooting first, so needing at first to carry out one after start judges, because determined this sub-district when starting shooting first, available adjacent sub-district, non-available adjacent sub-district and unified program list information all can be preserved, so receiving terminal judges whether self is that the mode of starting shooting first is in this step: determine whether to preserve this sub-district that pre-determines out, available adjacent sub-district, non-available adjacent sub-district and unified program list information, if do not have, then handle according to above-mentioned mode when starting shooting first, if have, then according to this sub-district, available adjacent sub-district, non-available adjacent sub-district and search remove this sub-district, the order of other sub-district beyond available adjacent sub-district and the non-available adjacent sub-district inserts successively, and is inserting successfully back execution in step 102.
Here the access success of being mentioned is meant the control channel data and the ESG information that can correctly read the sub-district.Because this accessed information such as this sub-district, available adjacent sub-district and non-available adjacent sub-district in start back is preserved before all being, and after this start, variation might take place in the RST of each sub-district, so whether each sub-district of preserving before need further determining by access procedure is available.
Concrete access way can be:
At first, use this sub-district to insert, if insert successfully, then execution in step 102;
If access failure, then use available adjacent sub-district insert (if available adjacent sub-district number greater than 1, then according to signal quality by inserting successively to bad order well), if insert successfully, then execution in step 102;
If access failure, it is (same then to use non-available adjacent sub-district to insert, if non-available adjacent sub-district number is greater than 1, then according to signal quality by inserting successively to bad order well), if insert successfully, the non-available adjacent sub-district that then will insert successfully is defined as this sub-district, and determines and preserve the available adjacent sub-district of the non-available adjacent sub-district of this access success, non-available adjacent sub-district and unified program list information, and execution in step 102 then;
If access failure, then use other sub-district except that above-mentioned this sub-district, available adjacent sub-district and non-available adjacent sub-district that searches to insert, if insert successfully, then will insert successful sub-district and be defined as this sub-district, and determine and preserve the available adjacent sub-district of the successful sub-district of this accesss, non-available adjacent sub-district and unify program list information that execution in step 102 then.
For non-available adjacent sub-district and other sub-district except that above-mentioned this sub-district, available adjacent sub-district and non-available adjacent sub-district, if insert successfully, so then this sub-district and the available adjacent sub-district of preserving before the explanation is unavailable, be adjusted into this sub-district so need to insert successful sub-district, and redefine and preserve the available adjacent sub-district of the successful sub-district of this access, non-available adjacent sub-district and unify program list information, concrete definite mode repeats no more as hereinbefore.
Step 102: determine that user selected program is that total program still is the exclusive program in this sub-district or available adjacent sub-district, if total program, then execution in step 103; If exclusive program, then execution in step 106.
Usually, corresponding two kinds of mode of operations of receiving terminal: idle pulley and business model.
In the present embodiment, under idle pulley, what receiving terminal will be done only is constantly to determine whether meet more new demand when precondition, if meet, then upgrade this sub-district, available adjacent sub-district, non-available adjacent sub-district and corresponding uniform program list information.
As well known to those skilled in the art, for receiving terminal, its the SINR value that can periodically carry out this sub-district is measured, but can periodically not measure the SINR value of adjacent sub-district, but apparent time machine and deciding, a kind of adjacent cell measurement definite method on opportunity is promptly proposed in the present embodiment, as follows:
Receiving terminal is being measured the SINR value SINR of this sub-district at every turn
This(n) after, at first with the SINR value SINR of itself and preceding this sub-district of once measuring
This(n-1) compare, if SINR
This(n) greater than SINR
This(n-1), promptly the twice SINR value in front and back is increase trend, thinks that then working as precondition does not meet more new demand, do not start adjacent cell measurement, still, and the available adjacent sub-district that minimizing is accordingly preserved and the SINR value of non-available adjacent sub-district, that is:
SINR
Adjacent '(n)=SINR
Adjacent '(n-1)-(SINR
This(n)-SINR
This(n-1)); (1)
Wherein, SINR
Adjacent '(n) the available adjacent sub-district of back (promptly reducing the back) and the SINR value of non-available adjacent sub-district, SINR are upgraded in expression
Adjacent '(n-1) the SINR value of (be preserve) available adjacent sub-district and non-available adjacent sub-district before expression is upgraded; For each available adjacent sub-district and non-available adjacent sub-district, all need handle according to mode shown in the formula (1).
If SINR
This(n) less than SINR
This(n-1), promptly the twice SINR value in front and back is minimizing trend, then further judges SINR
This(n) with available adjacent sub-district and non-available adjacent sub-district in the SINR value SINR of the best sub-district of signal quality
AdjacentWhether ratio (n-1) has promptly judged whether greater than predefined first threshold theeshold1
If formula (2) is set up, think that then working as precondition does not meet more new demand, do not start adjacent cell measurement, still, the available adjacent sub-district that increase is accordingly preserved and the SINR value of non-available adjacent sub-district, that is:
SINR
Adjacent '(n)=SINR
Adjacent '(n-1)+(SINR
This(n)-SINR
This(n-1)).(3)
If formula (2) is false, promptly have
Think that so then working as precondition meets update condition, needs to start adjacent cell measurement, but also needs further according to SINR
This(n) and SINR
Adjacent(n-1) comparative result of difference between and the predefined second threshold value threshold2 is determined startup opportunity:
If SINR
Adjacent(n-1)-SINR
This(n)＞threshold2; (5)
Then promptly start adjacent cell measurement at present frame;
Otherwise the T frame behind present frame starts adjacent cell measurement,
If the result of calculation of T is not integer, can round up.
In the subsequent process,, this sub-district, available adjacent sub-district, non-available adjacent sub-district and unified program list information are upgraded according to the adjacent cell measurement result.Specific implementation repeats no more.
The concrete value of above-mentioned each threshold value can be decided according to the actual requirements.In addition, for " equaling " this situation in above-mentioned each time relatively, can handle by the arbitrary mode in being greater than or less than.
Need to prove that only being in idle pulley with receiving terminal herein is example, the specific implementation of renewal process is described; For business model, above-mentioned renewal process will be suitable equally.
In addition, under business model, receiving terminal can receive user-selected program (user selects according to user's that receiving terminal is presented to unified program list information), and according to the difference of this selected program category, carry out different operations, if promptly selected program is total program, then execution in step 103, if be exclusive program, then execution in step 106.
Step 103: this cell channel parameter of utilizing total program correspondence, in this sub-district of total program correspondence, receive total program data, and judge whether and correctly to receive, if, then receiving back process ends (follow-up how the processing with scheme of the present invention has nothing to do, and is not described); Otherwise, execution in step 104.
Because the signal quality of this sub-district is best, so at first attempting utilizing this sub-district to have program data in this step receives, if the Packet Error Ratio continuous N frame of the program data that receives is greater than predefined the 3rd threshold value, think that then this sub-district can not correctly receive program data, thus execution in step 104.M is a positive integer, and the concrete value of its concrete value and the 3rd threshold value all can be decided according to the actual requirements.
Step 104: utilize the available adjacent cell channel parameter of total program correspondence, in the available adjacent sub-district of total program correspondence, receive total program data, and judge whether and correctly to receive, if, then receiving the back process ends, otherwise, execution in step 105.
If the available adjacent sub-district number of total program correspondence is greater than 1, need so at first to be sorted in the available adjacent sub-district of total program correspondence according to SINR value order from big to small, then, utilize the channel parameter that is in primary available adjacent sub-district after sorting to receive earlier and be somebody's turn to do total program data, if can correctly receive, be that Packet Error Ratio is less than the 3rd threshold value, then receiving the back process ends, if can not correctly receive, then utilize the channel parameter that is in deputy available adjacent sub-district after sorting to receive and should have program data, and the like.
If utilize a certain available adjacent sub-district successfully to receive this total program data, can further this available adjacent sub-district be adjusted into this sub-district so, this original sub-district is adjusted into adjacent sub-district.
Step 105: will have that the best sub-district of signal quality is adjusted into this sub-district in the available adjacent sub-district of program correspondence, and the output information, receive mistake with the prompting user, then process ends.
If the available adjacent sub-district of total program correspondence can not correctly receive this total program data, can from the available adjacent sub-district of total program correspondence, select the best sub-district of a signal quality so, it is adjusted into this sub-district, and the benefit of Chu Liing is convenient other program data that receives like this.
In addition, the particular content of information can be provided with arbitrarily on demand.
Step 106: this sub-district or the available adjacent cell channel parameter of utilizing exclusive program correspondence, in this sub-district of exclusive program correspondence or available adjacent sub-district, receive exclusive program data, and judge whether and can correctly receive, if then receiving the back process ends; Otherwise, execution in step 107.
Step 107: the output information receives mistake with the prompting user, then process ends.
In addition, if this exclusive program is the exclusive program in this sub-district, failing from available adjacent sub-district, to select the best sub-district of a signal quality after normal the reception, it is adjusted into this sub-district so.
