Description
A kind of method and client for generating file repairing requiring message
Technical field
The present invention relates to multimedia broadcasting and multicast service（MBMS) technology, espespecially a kind of method and MBMS clients for generating file repairing requiring message.Background of invention
In order to effectively utilize mobile communications network resource, 3G (Third Generation) Moblie global normalization tissue（3GPP) propose the MBMS of mobile communications network, so as to provide the point-to-multipoint service that a data source sends data to multiple users in the mobile communication network, network resources locating is realized, the utilization rate of Internet resources, interface resource of especially eating dishes without rice or wine is improved.The MBMS that 3GPP is proposed can not only realize message class multicast and the broadcast of plain text low rate, and can also realize multicast and the broadcast of high-speed multimedia service, and this has undoubtedly complied with the trend of following mobile data development.
It is an important technology in MBMS that file, which repairs flow, and the purpose is to repair loss or the damage of the MBMS file datas that MBMS files are caused in downloading process due to channel fading or other reasonses.The cylinder that file repairs flow wants the process to be：MBMS client downloads are to after MBMS files, MBMS files are checked, if there are the data of mistake in MBMS files, MBMS clients then send file repairing requiring message to file repair server, and demand file remediation server retransmits the data that there is mistake in MBMS files.The file repairing requiring message that file repair server is then sent according to MBMS clients, file repair response is returned to MBMS clients, the file repair response that MBMS clients are returned according to file repair server repairs mistake present in MBMS files.Here, file repairing requiring message and file repair response are based on http protocol.
MBMS files are by least one source block（Source Block) composition, each source block is again by several source symbols（Source Symbol) composition, while source symbol can be referred to as coded identification again.
Each source block is numbered with source block（SBN, Source Block Number) unique mark；Each source symbol is identified with coded identification（ESI) unique mark.The SBN of the first source block in MBMS files is 0, is expressed as SBN=0;The SBN of second source block is 1, is expressed as SBN=1, the rest may be inferred.Equally, the ESI values of first source symbol are 0 in source block, are expressed as SBN=0, ESI=0;The ESI values of second source symbol are 1 in source block, are expressed as SBN=0, ESI=1, the rest may be inferred.
MBMS files then use uniform resource identifier（URI unique mark) is carried out, the URI of MBMS files can be obtained from download distribution method.Therefore, the triple being made up of URI, SBN and ESI just can be with a coded identification in unique mark MBMS files.Here, signified coded identification refers to, in the specific file determined by triple, the particular source symbol of specific source block.
When MBMS files make a mistake, MBMS clients can be using the coded identification made a mistake, source block and file as a modification domain addition in file repairing requiring message.For example, in a MBMS download session, URI for www.example.com/news/latest.3gp MBMS file distributings to MBMS clients, but after MBMS file downloads are complete, client finds not receiving SBN=5 in the MBMS files, the source block of the coded identification and SBN=6 of ESI=12 and SBN=20, ESI=27.Now, when the URI of file repair server is http://mbmsrepairl.example.com/path/repair_script, MBMS client send file repairing requiring message be：
GET
/path/repair_scriptfileURI=www.example.com/news/latest.3gp&SBN=5 ； ESI=12&SBN=20;ESI=27 & SBN = 6
HTTP/1.1
Host: mbmsrepairl.example.com
Above-mentioned file repairing requiring message represents that biography is thought highly of in the multiple moon ^ business of file father that MBMS client requests URI is mbmsrepairl .example.com/path/repair_script, MBMS files URI=www.example.com/news/latest.3gp SBN=5, ESI=12
With the coded identification and the source block of SBN=6 of SBN=20, ESI=27.It can draw from the example above, be sequentially connected each modification domain, such as SBN=5 with ＆ in file repairing requiring message;ESI=12, SBN=20;ESI=27 and SBN=6.Modification domain includes according to actual situation：SBN symbols and ESI symbols or only include SBN symbols, for identifying the source block and coded identification of error.
When there are multiple coded identifications and/or source block error in a MBMS file, then can be using the mark of the coded identification of error and/or source block as an independent modification domain, it is added in after file URI, it so may result in that file repairing requiring message is very long, serious waste of resource.
Length additionally, due to file repairing requiring message defined in HTTP GET request message has certain limitations, the length of file repairing requiring message can not be lengthened unrestrictedly, therefore when the source block and/or too many coded identification made a mistake, file repairing requiring message can not carry vicious source block and/or the modification domain corresponding to coded identification.On the other hand, because file repairing requiring message is long, it can cause network congestion if multiple users send substantial amounts of request simultaneously, have a strong impact on the service quality of client.The content of the invention
In view of this, the main purpose of the embodiment of the present invention is to provide a kind of method for generating file repairing requiring message, can shorten the length of file repairing requiring message using this method.
In addition, the another main purpose of the embodiment of the present invention is to provide a kind of MBMS clients, the client can generate the file repairing requiring message of shortening.
To reach above-mentioned purpose, what the technical scheme of the embodiment of the present invention was realized in：A kind of method for generating file repairing requiring message, comprises the following steps：
Determine multiple data block errors in multimedia broadcasting and multicast service MBMS files；According to the data block of error, generation number is less than error data block number purpose and changes domain；The modification domain generated according to step and the uniform resource identifier of the MBMS files, it is raw
Into file repairing requiring message.
Meanwhile, the embodiment of the present invention additionally provides a kind of client, and the client further comprises, generation unit；
The generation unit, for receiving MBMS files, and when it is determined that multiple data blocks malfunction in the MBMS, according to the data block of error, generation number is less than error data block number purpose and changes domain；And the modification domain according to generation and the uniform resource identifier of the MBMS files, generate file repairing requiring message.
A kind of method for generation file repairing requiring message that the embodiment of the present invention is provided, can be it is determined that during MBMS document lendings, according to the data block of error, generate number and be less than error data block number purpose modification domain, and then be less than error data block number purpose modification domain generation file repairing requiring message using number is generated.Data block referred herein includes source block and coded identification.In embodiments of the present invention, because the modification domain by the source block to error and/or coded identification is merged, and from the number in the modification domain after merging is made less than the source block and coded identification malfunctioned, therefore relative to the method for changing domain for source block and the coded identification generation each malfunctioned in the prior art, the length of file repairing requiring message is greatly shortened.Meanwhile, the embodiment of the present invention provides a kind of MBMS clients again.The method and MBMS clients provided using the embodiment of the present invention, largely saved system resource, reduced message occupied bandwidth, it is ensured that network service is normally carried out.Brief Description Of Drawings
Fig. 1 is the flow chart of present invention method；
Fig. 2 is the structure chart of MBMS clients of the embodiment of the present invention.Implement the mode of the present invention
The core concept of the embodiment of the present invention is：It is determined that multiple data block errors in MBMS files
When, according to the data block of error, generation number is less than error data block number purpose and changes domain, to generate file repairing requiring message.Here, the data block of signified error according to the situations of different MBMS document lendings, source block or only coded identification may be included or including source block and coded identification, wherein it is one that the source block and/or coded identification that malfunction, which are more than,.Data block herein is the general name of source block and coded identification.
In embodiments of the present invention, generation number can be determined less than the operation that error data block number purpose changes domain according to the middle source block of error data block in MBMS files and the concrete condition of coded identification.It is preferred that can be operated according only to the source block in error data block or coded identification is operated or source block and coded identification are operated, it is less than error data block number purpose to generate and changes domain.
When the source block in according only to error data block is operated, first determine whether the source block with the presence or absence of error in the MBMS files of error, when there is the source block of error, preferably, a modification domain can be generated for the source block of all errors, domain is changed less than error data block number purpose to generate.Wherein, the method that the source block for multiple errors generates a modification domain, can be that the SBN values of the source block of multiple errors are assigned to the SBN symbols in a modification domain.For example, the SBN values of the source block of error are respectively：5th, 6,7,9,12 and 45, then can be for a modification domain of the source block generation of all errors： SBN = 5, 6, 7, 9, 12, 45.It is of course possible to method as described above, for the source block of all errors, generation number is less than the modification domain of error source block number, so can equally reach the purpose for reducing file repairing requiring message length.For example, the SBN values of the source block of error are respectively：5th, 6,7,9,12 and 45, then two modification domains of the source block production of all errors can be：SBN=5,6 and SBN=7,9,12,45.
When the coded identification in according only to error data block is operated, whether the multiple coded identifications of a source block are belonged in the data block for first determining whether error, when there is multiple coded identifications, one modification domain is generated according to the coded identification of this multiple error, is less than error data block number purpose modification domain to generate.Specific method can be, the source that the multiple coded identification is belonged to
The SBN values of block assign the SBN symbols in the modification domain, and the ESI values of the multiple coded identification are assigned to the ESI symbols in the modification domain.For example, the SBN values and ESI values of the coded identification of error are respectively：（SBN=5, ESI=2)、 （SBN=5, ESI=6 )、 （SBN=5, ESI=7 )、 (SBN=5, ESI=8)、 （SBN=5, ESI=18) and（SBN=5, ESI=28), shellfish ' a modification domain that the source block of all errors of J is targeted can be：（SBN = 5, ESI = 2, 6, 7, 8, 18, 28).
When the coded identification malfunctioned in the data block of error belongs to multiple different source blocks, then a modification domain can be generated for each source block.For example, SBN the and ESI values of the coded identification of error are respectively：（SBN=5, ESI=2)、 （SBN=5, ESI=6 )、 （SBN=5, ESI=7 )、 (SBN=6, ESI=8)、 （SBN=6, ESI=18) and（SBN=6, ESI=28), then two targeted modification domains of the source block of all errors can be：（SBN=5, ESI=2,6,7) and (SBN=6, ESI=8,18,28).In embodiments of the present invention, it will be bracketed for the modification domain user's bracket for encoding source block, it is therefore an objective to distinguish each modification domain, not representing also has same form in file repairing requiring message.
Certainly when generating number less than error coding symbol number purpose modification domain, also it is not necessarily required to generate a modification domain for the multiple coded identifications for belonging to a source block.For example for (SBN=5, ESI=2),（SBN=5, ESI=6 )、 （The situation of SBN=5, ESI=7), then can generate two modification domains is respectively：（SBN=5, ESI=2,6) and（SBN=5, ESI=7), it so can equally reach the purpose for reducing file repairing requiring message length.
When being operated according to source block and coded identification included in error data block, source block and coded identification with the presence or absence of error in the MBMS files of error must be then judged respectively, then according to error source block and the reality of error coded identification, generation number is less than error data block number purpose and changes domain.Processing method for error source block and the coded identification that malfunctions is identical with the processing of foregoing description, will not be described in detail herein.
For the object, technical solution and advantage of the embodiment of the present invention are more clearly understood, join below
Developed simultaneously embodiment according to accompanying drawing, the embodiment of the present invention is described in further detail.
Fig. 1 is the flow chart of present invention method, is specifically described as follows：
Step 101:When a MBMS file is distributed to after MBMS clients, MBMS clients then after MBMS file downloads are finished, judge whether the MBMS files malfunction, if it is, performing step 102;Otherwise, step 108 is performed.
Step 102:It is determined that there is the source block and/or coded identification of multiple errors.
In a step 102, the source block and coded identification of error can be recorded by recording the source block of error and the mark of coded identification.When source block malfunctions, then the SBN values of source block are recorded；When coded identification malfunctions, then the ESI values in the source block of SBN values and coded identification of the source block where coded identification are recorded.In embodiments of the present invention, it will be used to identify that the SBN of source block is referred to as the mark of source block；It will be used to identify that the SBN and ESI of coded identification are referred to as the mark of coded identification.
Wherein, judge in step 101 the MBMS files whether malfunction and step 102 in determine error source block and coded identification method can use prior art method.
Step 103:The source block of multiple errors is judged whether, if it is, performing step 104;Otherwise, step 105 is performed.
Here judging whether the source block of multiple errors can be judged according to the mark of record, be specially：Judge to whether there is multiple SBN values in the mark of record, if it is, there is the source block of multiple errors；Otherwise, in the absence of the source block of multiple errors.Here, the SBN values be it is relative with for SBN the and ESI values of identification code symbol, because only that single SBN values are for identifying source block.Meanwhile, the multiple of meaning refer to being more than or equal to 2 in the present invention.
Step 104:The source block of this multiple error is obtained, the mark of the source block of this multiple error a modification domain is generated into, for generating current file repairing requiring message.
Here, search and obtain the source blocks of multiple errors and can also be performed according to the mark of record, specially：The SBN values of all records are obtained, these SBN values correspondence source block is the source block of error.
Wherein, the mark of the source block of multiple errors is generated into a modification domain is：By this multiple error
The mark of source block assigns the SBN symbols in modification domain.For example, the SBN values of the source block of error are respectively：5th, 6,7,9,12 and 45, then targeted one modification domain of the source block of all errors can be： SBN = 5, 6, 7, 9, 12, 45.Here, the connector between each SBN values is not limited to comma, as long as the connector that http protocol is supported can.Here, the connector of such as comma etc is properly termed as generic connectivity symbol, and the method that each value is attached with comma is referred to as generic connectivity method.
In this step, it can further include, judge whether the continuous source block of SBN values, if it is present when representing continuous SBN values, continuous value part is represented with successive value representation.Successive value representation is：The initial value and most end value of continuous SBN values, along with that can represent the continuously coupled symbol of serial relation, for example, being similarly example described above, modification domain can be expressed as：SBN=5-7,9,12,45, wherein, middle thick stick is can to represent the continuously coupled symbol of serial relation.Certainly, according to http protocol, can also use can represent the connector of serial relation, such as underscore.Successive value representation can add the number of contact value, such as SBN=5+3,9,12,45 with the initial value of continuous SBN values.SBN=9,12,45 these discontinuous values can also be referred to as discontinuous SBN values simultaneously.
Step 105:Judge whether to belong to the coded identification of multiple errors of a source block, if it is, performing step 106;Otherwise, step 107 is performed.Specially：Judge multiple error coded identifications with the presence or absence of specific identical SBN values in the mark of record, i.e., there are multiple different ESI values corresponding to same SBN, if it is, in the presence of the coded identification for the multiple errors for belonging to a source block；Otherwise, in the absence of the coded identification for the multiple errors for belonging to a source block.
Step 106:During implementing, there may be multiple source blocks as described in step 105, there is the coded identification of multiple errors in this each source block, so it is directed to each source block, the mark of the coded identification of all errors included by the source block is generated into a modification domain, for generating current file repairing requiring message.
Specially：All coded identifications that there is mistake are classified, by with identical SBN's
Then coded identification generates a modification domain as a class for every class source block.Wherein, generating a modification domain for every class source block is：The SBN values of source block are assigned to the SBN symbols in modification domain, the ESI values of the coded identification of multiple errors in the source block are assigned to the ESI symbols in the modification domain.For example, SBN the and ESI values of the coded identification of error are respectively：（SBN=5 , ESI=2 )、 ( SBN=5 , ESI=6 )、 （SBN=5 , ESI=7 )、 （SBN=5 , ESI=8 )、 （SBN=5, ESI=18) and（SBN=5, ESI=28), then corresponding modification domain can be： SBN = 5, ESI = 2, 6, 7, 8, 18, 28.Here, the connector between each ESI values is not limited and comma, can also make pause mark, as long as the connector that http protocol is supported can.
In this step, it can further include, judge whether the continuous coded identification of ESI values, if it is present when representing continuous ESI values, continuous value part is represented with successive value representation.Successive value representation can be indicated with the initial value and most end value of continuous SBN values plus continuously coupled symbol, for example, being similarly example described above, modification domain can be expressed as： SBN = 5, ESI = 2, 6-8, 18, 28.Successive value representation can add the number of contact value, such as SBN=5, ESI=2,6+3,18,28 with the initial value of continuous ESI values.Here it is possible to which ESI=2,18,28 value are referred to as into discontinuous ESI values.
Step 107:File repairing requiring message is generated according to the modification domain of generation.
Here, the modification domain of the generation, is generated according to actual conditions by step 104 and/or step 106.In this step, the modification domain generated by step 104 and/or step 106 is connected with ＆ symbols successively, carries in file repairing requiring message after the URI of current MBMS files, generate file repairing requiring message.
The current MBMS document lendings due to being had determined that in step 101, therefore step 104 and step 106 can at least generate modification domain in the presence of a step, therefore in step 107, the modification domain inherently generated according to step 104 and/or step 106, generates file repairing requiring message.
Step 108:Terminate currently processed flow.
Here, step 105 can also be performed before step 103, i.e., after execution of step 105 or step 105 and step 106, then perform step 103;Step 105 can also simultaneously be performed with step 103, i.e., step 103 and step 104 and step 105 and step 106 are the relations of parallel processing.
Because MBMS clients and file repair server are all based on http protocol, and the embodiment of the present invention is also to be carried out on the base of http protocol, therefore file repair server can parse the file repairing requiring message in the embodiment of the present invention transmitted by MBMS clients.
Fig. 2 show the structure chart of MBMS clients, and the client further comprises, generation unit 21.The generation unit 21, for receiving MBMS files, and when it is determined that multiple data blocks malfunction in MBMS, according to the data block of error, generation number is less than error data block number purpose and changes domain；And the modification domain according to generation and the uniform resource identifier of MBMS files, generate file repairing requiring message.
It is preferred that generation unit 21 can be constituted by changing domain generation unit 211 and message generation unit 212.Wherein change domain generation unit 211, for receiving MBMS files, and when it is determined that multiple data blocks malfunction in MBMS files, according to the data block of error, generate number and be less than error data block number purpose modification domain, and modification domain is sent to message generation unit 212.Message generation unit 212, for according to the modification domain received from modification domain generation unit 211 and the uniform resource identifier of MBMS files, generating file repairing requiring message.Here, modification domain generation unit is according to the data block of error, and generation number is less than the method that error data block number purpose changes domain, identical with the method described in the embodiment of the present invention, will not be described in detail herein.
