The invention discloses a method, device and system for allocating air interface resources, belonging to the communication field. The method comprises the steps of: obtaining a first level and a second level which correspond to a channel group according to data volume buffered in a buffer corresponding to the channel group, wherein the first level is used for indicating a section of number range,the second level is used for further indicating the number range where the data volume is in the section of number range; filling the first level in a BSR (Buffer State Report) control element of a BSR message and the second level in a BSR head of the BSR message; and sending the BSR message to a base station and requesting the base station for allocating the air interface resources. The system comprises a terminal and the base station. The terminal comprises a first acquisition module, a first filling module and a sending module. The base station comprises a first extraction module, a secondacquisition module and an allocation module. The invention can enhance the utilization rate of the air interface resources.
 在无线通信系统中，终端通过信道组向基站发送数据之前，基站需要先确定为该信道组分配空口资源的大小，然后再分配确定大小的空口资源，终端再通过该信道组以及利用分配的空口资源发送数据给基站。 Before  In a wireless communication system, the terminal transmits data channel groups to the base station through the base station needs to determine the size of the allocated air interface resource channel group for, and then redistributed to determine air interface resource size, the terminal and then through the channel groups, and the use of air interface transmission resource allocation data to the base station.
 现有技术提供了一种分配空口资源的方法，具体为：终端和基站事先存储相同的数值范围与BSR (Buffer Status Iteport，缓冲器状态报告）级别的对应关系表，当终端需要通过信道组传输数据时，终端统计该信道组对应的缓冲器中缓存的数据量，确定统计的数据量所在的数值范围，根据确定的数值范围，从数值范围与BSR级别的对应关系表中获取对应的BSR级别，将获取的BSR级别填写在BSR消息中并发送该BSR消息给基站；基站接收该BSR消息且从该BSR消息中提取BSR级别，根据提取的BSR级别，从数值范围与BSR级别的对应关系表中获取对应的数值范围，将获取的数值范围的上限值确定为为该信道组分配的空口资源的大小，再分配确定大小的空口资源。  The prior art provides a method of allocating air interface resources, in particular: previously storing terminal and the base station of the same numerical value ranges BSR (Buffer Status Iteport, a buffer status report) level correspondence table, when a terminal needs by the channel set of transmission data, the terminal statistics data in the buffer cache of the channel group corresponding to the determined range of values ​​the amount of statistical data is located, to acquire a corresponding number from the scope of the BSR level correspondence table based on the determined range of values the BSR level acquired BSR level of fill in the BSR message and transmits the BSR message to the base station; base station receives the BSR message and the extraction BSR level from the BSR message, according to the BSR levels of abstraction, from a numerical range with BSR level upper limit value acquiring correspondence table corresponding to a numerical range, the obtained range of values ​​determined for the size of the air interface resource allocation channel group, is determined reallocation of air interface resource size.
 其中，BSR消息包括BSR子头和BSR控制元且BSR控制元中包括缓存大小字段，缓存大小字段占用6个比特且其用于填写BSR级别，所以BSR级别包括64种BSR级别，即第0级别至第63级别，而每个BSR级别对应一个数值范围，所以终端与基站中的数值范围与BSR级别的对应关系表中只有64种BSR级别和64种数值范围。  wherein, BSR BSR message includes a header and a sub BSR BSR control element and the control element comprises a cache size field, the buffer size field occupies 6 bits and which is used to fill BSR level, so BSR BSR level includes 64 kinds of levels, i.e., level 0 to level 63, and each BSR level corresponds to a range of values, only 64 kinds of BSR and 64 kinds of numerical ranges level terminal with a numerical range with a base station BSR level correspondence table.
 由于只能在BSR消息中填写64种BSR级别，而每种BSR级别对应一种数值范围， 数值范围划分的不够细致，使基站确定的空口资源的大小与终端的缓冲器中缓存的数据量之间的差值较大，从而存在大量的空口资源未被充分使用，而在无线通信领域，空口资源是很宝贵的，现有技术这种不必要的空口资源浪费降低了通信资源的利用率。  Since only fill level in the 64 kinds of BSR BSR message, and each level corresponding to the BSR A numerical range, value range is divided not detailed enough, so that the buffer size and the air interface resources of the terminal station determines the cached the difference between the large amount of data, so that there is a large amount of air interface resources are not fully utilized, and in the field of wireless communication, air interface resources are very valuable, the prior art this unnecessary waste of air interface resources, communication resources is reduced utilization.

 本发明实施例通过在BSR消息的BSR控制元中填写第一级别，在BSR消息的BSR子头的保留字段中填写第二级别，可以通过第一级别和第二级别的组合对应一个数值范围， 从而能够使数值范围划分的更加细致，减小基站确定的空口资源的大小与终端中缓存的数据量的差值，从而提高了空口资源的利用率，节省了空口资源。  Example BSR BSR messages through the control element in the embodiment of the present invention to fill the first level, a second level of fill in the reserved field of the sub-header BSR BSR message, may correspond to a first level and the second by a combination of level range of values, thereby enabling more detailed numerical range is divided, the size difference is reduced and the amount of data buffered in the terminal air interface resources of the base station is determined, thereby improving the utilization of air interface resources, save air interface resources.

 如果终端的信道组对应的缓冲器中缓存有需要传输给基站的数据，则终端发送BSR消息给基站，请求基站分配用于传输数据的空口资源。  If the cache data should be transferred to the base station, the terminal transmits the BSR message to the base station, the base station requesting allocation of air interface resources for data transmission channel group corresponding to a terminal of the buffer. BSR消息包括BSR子头和BSR控制元，且BSR消息又可以分为短BSR消息和长BSR消息。 BSR BSR message includes a sub-header and the BSR control element, and the BSR message can be divided into short and long BSR BSR message message. 如果终端只有一个信道组的缓冲器中缓存有需要传输的数据，则终端发送的BSR消息为短BSR消息；如果终端有多个信道组的缓冲器中缓存有需要传输的数据时，则终端发送的BSR消息为长BSR消息。 If the terminal is only one channel group of the buffer cache data needs to be transmitted, the BSR message transmitted by the terminal is short BSR message; if the terminal has data to transmit buffer of the plurality of channel groups buffers, the terminal transmits the message is a long BSR BSR message.
 其中，短BSR消息包括BSR子头和BSR控制元，如表1所示，短BSR消息的BSR子头包括BSR标识字段LC ID、扩展域标识字段E和保留字段RR;标识字段LC ID占用五个比特且其值为11101，用于标识短BSR消息，扩展域标识字段E占用一个比特，保留字段RR占用两个比特且其值为空。  wherein the message comprises a short BSR and subheader BSR BSR control element, as shown in Table. 1, the short BSR BSR sub-header comprises a message identification field LC BSR ID, extension field identification field and a reserved field E the RR; LC identifier field ID occupies five bits and a value of 11101, for identifying the short BSR message identifier field E extension field occupies one bit, two bits reserved field occupies RR and is null.
 如表2所示，短BSR消息的BSR控制元包括信道组标识LCG ID和缓存大小字段Buffer Size，缓存大小字段Buffer Size占用六个比特，信道组标识LCG ID占用两个比特， 所以终端与基站之间最多具有4个信道组。  As shown in Table 2, the short BSR BSR control element comprises a message identification channel groups and cache size of the LCG ID field Buffer Size, the size of the buffer Buffer Size field occupies six bits, the channel group identification LCG ID occupies two bits, It has up to four channel groups between the terminal and the base station.
 其中，如果终端有多个信道组的缓冲器中缓存有需要传输的数据，则终端发送长BSR消息给基站。  wherein, if the terminal has a buffer channel groups of the plurality of buffers data to be transmitted, the terminal transmits a long BSR message to the base station. 长BSR消息包括BSR子头和BSR控制元，如表3所示，长BSR消息的BSR 子头包括BSR标识字段LC ID，扩展域标识字段E和保留字段RR;标识字段LC ID占用五个比特且其值为11110，用于标识长BSR消息，扩展域标识字段E占用一个比特，保留字段RR 占用两个比特且其值为空。 A long BSR comprises a message header and a sub BSR BSR control element, as shown in Table 3, the long BSR BSR message subheader including identification BSR LC ID field, an extension field identifying a reserved field and the RR field E; LC ID identifier field occupies five bits 11110 and its value is used to identify the long BSR message identifier field E extension field occupies one bit, two bits reserved field occupies RR and is null.
 其中，长BSR消息的BSR控制元包括多个缓存大小字段Buffer Size，如表4所示， 长BSR消息的BSR控制元包括4个缓存大小字段Buffer Size，且每个缓存大小字段Buffer Size都占用六个比特。  wherein, long BSR BSR control element comprises a plurality of message buffer size field Buffer Size, as shown in Table, 4 long BSR BSR control element comprises a message size field four buffers Buffer Size, Buffer Size field of each cache and Size occupies six bits.
 步骤103 ：发送BSR消息给基站，请求基站分配空口资源。  Step 103: Send a message to the BSR the base station, the base station requesting allocation of air interface resources.
 在本发明实施例中，在BSR消息的BSR控制元中填写第一级别，在BSR消息的BSR 子头的保留字段中填写第二级别，所以可以通过第一级别和第二级别的组合对应一个数值范围，从而能够使数值范围划分的更加细致，减小基站确定的空口资源的大小与终端中缓存的数据量的差值，从而提高了空口资源的利用率，节省了空口资源。  In an embodiment of the present invention, the fill level of the first message BSR BSR control element, the fill level in the second sub-header reserved field of BSR BSR message, it is possible by the first level and the second level combination corresponds to a range of values, thereby enabling more detailed numerical ranges divided, reducing the amount of difference of the data size of the terminal air interface resources of the base station the determined cache, thereby improving the utilization of air interface resources, save air interface resources.
 其中，第一级别用于指示一段数值范围，第二级别用于在第一级别指示的一段数值范围内进一步指示更具体的数值范。  wherein the first period of a numerical range for indicating the level, second level within a range of values ​​for a first class indication further indicates a more specific range of values.
 步骤203 ：为该信道组分配获取大小的空口资源。  Step 203: channel group assignment for acquiring the size of the air interface resources.
 其中，终端与基站之间的每个信道组都有对应的缓冲器，终端通过某个信道组发送数据给基站之前，先将需要发送的数据缓存在该信道组对应的缓冲器中。  wherein each channel group between the terminal and the base station has a corresponding buffer, the terminal transmits data via a channel to the group prior to the base station, first data buffer needs to be sent in the channel buffer corresponding to the group . 当终端将需要发送的数据缓存在该信道组对应的缓冲器中后，终端需要向基站请求分配传输数据的空口资源。 When the data buffer to be transmitted by the terminal in the channel group corresponding to the channel buffer, the terminal needs to request resource allocation of an air interface for transmitting data to a base station.
 例如，终端需要通过信道组标识2对应的信道组传输数据给基站且向该信道组对应的缓冲器中缓存需要传输的数据，然后终端统计该信道组对应的缓冲器中的数据量，其中，该信道组的标识2的二进制码为10且终端统计的数据量为100个字节。 Channel burst data  For example, the terminal needs to identify 2 corresponding to the channel group to the base station and to the channel group corresponding to the channel buffer cache data to be transmitted, the amount of data channel group corresponding to the channel buffer and the terminal count wherein identifying the set of binary code channel 2 is the terminal 10 and the amount of data statistics 100 bytes.
 其中，在本实施例中，对现有的数值范围与BSR级别的对应关系表中的64个数值范围进行进一步地划分，具体为：针对现有的数值范围与BSR级别的对应关系表中的任一条记录，将该记录包括的BSR级别作为第一级别，以及对该记录包括的数值范围进行进一步划分得到多个数值范围，并设置划分的每个数值范围对应一个第二级别，所以划分的每个数据值范围都对应一个由第一级别和第二级别组合的级别，然后将划分的每个数值范围、每个数值范围对应的由第一级别和第二级别组合的级别存储在数值范围与级别的对应关系表中。  In the present embodiment, a numerical range of 64 conventional numerical range BSR level correspondence table is further divided, in particular: a correspondence relationship with the numerical range of the existing level BSR table according to any one record, the record level as the BSR includes a first level, and the record includes a range of values ​​obtained by further dividing a plurality of numerical ranges, each numerical range is divided and arranged corresponding to a second level, Therefore, each data value corresponds to a divided range, then each of the divided numerical range, each range of values ​​corresponding to the level stored by the first level and the second level of the first level by the combination of level and the second level of combined in the numerical range of the level correspondence table. 按上述方法，对现有的数值范围与BSR级别的对应关系表中其他每条记录中的数值范围进行划分。 As described above, a numerical range of a conventional numerical range BSR level correspondence table each record other divided. 所以最终得到的数值范围与级别的对应关系表中包括64个第一级别， 且每个第一级别对应多个数值范围，以及每个第一级别对应多个第二级别。 Therefore, the numerical range of the level correspondence table finally obtained 64 comprises a first level, and each level corresponding to a first plurality of numerical ranges, and each level corresponding to a first plurality of second level.
 例如，假设现有的数值范围与BSR级别中存在一条包括数值范围为90至106个字节以及BSR级别为5的记录，将该记录中的BSR级别5作为第一级别，将该记录中的数值范围90至105个字节划分成4个数值范围，分别为90至93个字节、94至97个字节、98至101个字节以及102至105个字节；且为划分的每个数值范围设置第二级别，分别为0、1、2 和3，所以划分的数值范围90至93个字节对应一个由第一级别5和第二级别0组合的级另IJ，划分的数值范围94至97个字节对应一个由第一级别5和第二级别1组合的级别，划分的数值范围98至101个字节对应一个由第一级别5和第二级别2组合的级别，划分的数值范围102至105个字节对应一个由第一级别5和第二级别3组合的级别。  For example, assuming a conventional BSR level value range comprises a range of values ​​is present from 90 to 106 bytes and record level 5 BSR, the BSR record level as the first 5 level, the record numerical range from 90 to 105 bytes is divided into four ranges of values, respectively, from 90 to 93 bytes, 94-97 bytes, 98-101 bytes and bytes 102-105; and is every numerical range divided a second level, respectively 0, 1 and 3, the numerical value range divided 90-93 bytes corresponding to a first level of another IJ stage 5 and a second combination of level 0, the divided value range from 94 to 97 bytes of a level corresponding to the combination of a first level and a second level 1 5, the divided value range from 98 to 101 bytes corresponding to a combination of a first level and a second level 2 of 5 level, the divided value range from 102 to 105 bytes corresponding to a level of a first level and a second level combination 5 3. 然后将划分的数值范围以及由第一级别和第二级别组合的级别存储在如表5所示的数值范围与级别的对应关系表中。 Then the level value range value range divided by the first composition and level storage level and the second level as shown in Table 5 in the correspondence table.
 其中，根据统计的该信道组对应的100个字节的数据量，确定出该信道组对应的数据量所在的数值范围为98至101个字节之内。  wherein the channel set according to an amount corresponding to 100 bytes of data statistics, determined within 98 to 101 bytes of the data track set value range corresponding to the amount of the letter is located.
[0071 ] 其中，在本实施例中，终端和基站都存储相同的数值范围与级别的对应关系表，即在终端和基站中都存储如表5所示的数值范围与级别的对应关系表。  In the present embodiment, the terminal and the base station store the same numerical range correspondence table level, i.e., the terminal and the base station are stored as table values ​​in the range of level correspondence table shown in FIG. 5.
 其中，在本发明实施例中，数值范围与级别的对应关系表中包括64个第一级别， 每个第一级别对应多个数值范围，所以终端与基站中的数值范围与级别的对应关系表中包括的数值范围比现有的数值范围与BSR级别的对应关系表中包括的数值范围更细致。  wherein, in the embodiment of the present invention, the numerical range of the level correspondence table 64 includes a first level, a first level corresponding to each of a plurality of numerical ranges, the terminal and the base of the numerical ranges and levels correspondence table comprises a range of values ​​of the numerical range than conventional BSR level correspondence table included in the more detailed range of values.
 具体地，终端根据确定该信道组对应的数值范围，从已存储的数值范围与级别的对应关系表中获取该信道组对应的第一级别和第二级别。  Specifically, the terminal according to the determined range of values ​​corresponding to the channel group, obtaining the first level and a second level corresponding to the channel from the set value range and level correspondence table has been stored.
 例如，根据确定该信道组对应的数值范围98至101个字节，从如表5所示的数值范围与级别的对应关系表中获取该信道组对应的第一级别5和第二级别2。  For example, the numerical range is determined according to channel group corresponding to 98 to 101 bytes, the first level of the acquired channel group corresponding to the numerical range such as from the level correspondence table as shown in Table 5 and second 5 level 2.
 进一步地，终端还可以将该信道组的标识填写在BSR控制元的信道组标识字段中。  Furthermore, the terminal can identify the channel group to fill in the channel group identification field in the BSR control element.
 例如，第一级别5的二进制为000101，终端将该信道组对应的第一级别000101填写在BSR控制元的缓存大小字段中以及将该信道组的标识10填写在BSR控制元的信道组标识字段中，得到的BSR控制元如表6所示。  For example, a first binary level is 5 000 101, the channel group corresponding to a terminal of a first buffer size level of 000101 to fill in the fields in the BSR control element and identifying the channel groups fill channel 10 BSR control element group identifier field, the BSR control element is obtained as shown in table 6.
 其中，第二级别2的二进制为10，终端将该信道组对应的第二级别10填写在BSR 子头的保留字段中，得到的BSR子头如表7所示。  wherein the second binary level 2 is 10, the second level of the terminal corresponding to the channel group 10 to fill in the reserved field BSR sub-header, the subheader BSR obtained as shown in Table 7.
 其中，BSR消息由如表7所示的BSR子头和如表6所示的BSR控制元组成，然后终端再将如表7和6组成的BSR消息发送给基站。  wherein, the message BSR BSR control element composition shown in FIG. 6, 7 and 6 and then the terminal BSR message to the base station as the composition of the BSR Table subheader as shown in Table 7 and such.
 其中，在本实施例中，将第二级别填写在BSR子头的保留字段中，保留字段占用两个比特，所以每个第一级别可以最多对应4个第二级别，因此每个第一级别可以最多对应4 个数值范围。  In the present embodiment, the second level of fill in the reserved field in the BSR sub-header, reserved field occupies two bits, so that each may correspond to a first level of a second level up to four, so that each The first level may correspond to up to four numerical ranges.
 具体地，基站接收BSR消息，从该BSR消息的BSR控制元中提取第一级别，以及从该BSR消息的BSR子头的保留字段中提取第二级别。  Specifically, the base station receives the BSR message, extracting from the first level BSR control element of the BSR message, the second level and extracting from the sub-header reserved field BSR in the BSR message.
 进一步地，基站还可以从该BSR消息的BSR控制元中提取信道组标识。  Furthermore, the base station control element may also be extracted from the channel group identification of the BSR BSR message.
 例如，基站从BSR消息的BSR控制元中提取第一级别5和信道组标识2，从该BSR 消息的BSR子头中提取第二级别2。  For example, BSR BSR message from the base station to extract a first level element 5 and the second control channel group ID, the sub-header is extracted from BSR BSR second level 2 message.
 具体地，基站根据提取的该信道组对应的第一级别和第二级别，从已存储的数值范围与级别的对应关系表中获取该信道组对应的数值范围。  Specifically, the base station, obtaining the numerical range corresponding to the channel group from a numerical range with channel level correspondence table stored in the channel based on the extracted set of corresponding first level and the second level.
 步骤307 ：基站将获取的数值范围的上限值确定为为该信道组分配的空口资源的大小，分配确定大小的空口资源。  Step 307: the upper limit of the numerical range of the acquired base station determines the size of the air interface resources allocated to the channel group is assigned to determine the size of the air interface resources.
 其中，基站分配确定大小的空口资源后，返回响应消息给终端，然后终端通过该信道组且利用分配的空口资源将该信道组对应的缓冲器中缓存的数据传输给基站。  wherein, after the base station allocates determined air interface resource size, and returns a response message to the terminal, then the terminal by corresponding to the channel group, and using the allocated air interface resource the channel set of buffers cached data to the base station. 当然，在实际应用中也可以对分配的空口资源大小进行灵活的调整，即可以将略小于或略大于所述上限值对应的资源量的值作为分配的大小，本实施例对此不做限制。 Of course, can be adjusted flexibly allocated air interface resource size in practical applications, i.e., may be slightly smaller or slightly larger than the value of the upper limit of the amount of resources as corresponding to the allocated size, the present embodiment does not limit.  例如，基站根据该信道组对应的第一级别5和第二级别2，从自身存在的如表5所示的数值范围与级别的对应关系表中获取对应的数值范围为98至101个字节，将获取的数值范围的上限值101作为为信道组标识2对应的信道组即为该信道组分配空口资源的大小。  For example, the base station 2 acquires the corresponding range of values ​​from the numerical range such as level correspondence table shown in Table 5 according to present itself to the channel group corresponding to the first level and the second level is 5 98-101 bytes, the upper limit of the numerical range is acquired as a channel group 101 channel group identifier 2 corresponding to the size of the channel group is assigned air interface resources shall be.
 例如，终端包括四个信道组分别为第一信道组、第二信道组、第三信道组和第四信道组，终端需要利用四个信道组传输数据，并统计每个信道组对应的缓冲器中缓存的数据量，假设统计的第一信道组对应的缓冲器中缓存的数据量为100个字节、第二信道组对应的缓冲器中缓存的数据量为93个字节、第三信道组对应的缓冲器中缓存的数据量为95个字节、第四信道组对应的缓冲器中缓存的数据量为96个字节。  For example, the terminal includes four channel groups respectively, a first channel group, second channel, third channel and fourth channel groups, the terminal needs to use the four channels set of transmission data, and statistics for each channel group corresponding to the amount of data in the buffer cache, assuming the amount of data corresponding to a first set of statistics of the channel buffer cache is 100 bytes, the amount of buffered data in the buffer corresponding to a second channel group of 93 bytes, the amount of data in the buffer cache corresponding to the third signal channel group is 95 bytes, the amount of data for the fourth channel group corresponding to the cache buffer is 96 bytes.
 例如，确定出第一信道组对应的数据量100个字节所在数值范围为98至101个字节，确定出第二信道组对应的数据量93个字节所在数值范围为90至93个字节，确定出第三信道组对应的数据量95个字节所在数值范围为94至97个字节以及确定出第四信道组对应的数据量96个字节所在数值范围为94至97个字节。  For example, the numerical range determining an amount of data corresponding to a first channel group 100 Byte channel is 98 to 101 bytes, it is determined that the amount of data of the second channel group corresponding to the byte where the value range 93 to 90 93 bytes, it is determined that the numerical ranges corresponding to the amount of data channel group 95 byte third channel is 94 to 97 bytes of data and determining the amount of channel group corresponding to a fourth channel 96 byte values ​​range from 94 to 97 bytes.
 其中，在本实施例中，终端和基站都存储如表5所示的数值范围与级别的对应关系表。  In the present embodiment, the terminal and the base station are stored as table values ​​and the range of level correspondence table shown in FIG. 5. 另外，终端还发送长BSR消息给基站，而长BSR消息包括一个BSR子头，但BSR控制元包括多个缓存大小字段，所以长BSR消息的BSR子头中只能填写一个信道组的第二级别， 在本实施例中，可以根据预设的规则选择一个信道组，将选择的信道组的第二级别和第一级别填写在BSR子头和BSR控制元中，将其他未选择的信道组对应的第一级别填写在BSR 控制元中。 In addition, the terminal also sends a message to the base station long BSR, and the long BSR BSR message includes a sub-header, the BSR control element comprises a plurality of cache size field, so long BSR BSR sub-header of the message can only fill one channel of the second group level, in the present embodiment, can select a channel group according to a predetermined rule, the second level and the first level channel group will be chosen to fill the BSR sub-header and a BSR control element, the other channel group is not selected corresponding to the first level of fill in the BSR control element. 预设的规则可以为选择优先级最大的信道组。 Preset rule may select the maximum priority channel group.
 具体地，根据预设的规则选择一个信道组，根据选择的信道组对应的数值范围，从已存储的数值范围与级别的对应关系表中获取选择的信道组对应的第一级别和第二级别。  In particular, selecting a channel group according to a preset rule, obtaining a first level corresponding to the channel group selected from a numerical range with a level correspondence table stored in accordance with a numerical range channel group corresponding to the selected and second level.
 例如，假设第一信道组的优先级最大，根据预设的规则选择第一信道组，根据第一信道组对应的数值范围98至101个字节，从如表5所示的数值范围与级别的对应关系表中获取对应的第一级别5和第二级别2。  For example, assuming the maximum priority of the first channel group, selecting a first channel group according to a predetermined rule, according to the value range of the first channel group corresponding to 98 to 101 bytes, the values ​​as shown in Table 5 level range correspondence table acquired in the corresponding first level and a second level 2 5.
 具体地，终端根据其他每个未选择的信道组对应的数值范围，从已存储的数值范围与级别的对应关系表中获取其他每个未选择的信道组对应的第一级别。  Specifically, the terminal according to the value range of each other unselected channel group corresponding to a first level for additional channel for each non-selected group from the numerical range corresponding to the level correspondence table has been stored.
 例如，其他未选择的每个信道组分别为第二信道组、第三信道组和第四信道组；终端根据第二信道组对应的数值范围90至93个字节、第三信道组对应的数值范围94至97 个字节以及第四信道组对应的数值范围94至97个字节，分别从如表5所示的数值范围与级别的对应关系表中获取第二信道组对应的第一级别为5、第三信道组对应的第一级别为5以及第四信道组对应的第一级别为5。  For example, the other non-selected group of each channel are a second channel, third channel and fourth channel groups; terminal according to a second range of values ​​corresponding to the channel set 90 to 93 bytes, the third channel range of values ​​corresponding to the group 94 to 97 bytes, and the numerical range corresponding to a fourth channel group from 94 to 97 bytes, are acquired from the second channel group corresponding to the numerical range such as level correspondence table as shown in table 5 5 is a first level, a first level corresponding to a third channel group 5 is a first level and a fourth channel group is corresponding to 5.
 其中，在本实施例中，事先约定BSR控制元中的第一个缓存大小字段、第二个缓存大小字段、第三个缓存大小字段以及第四缓存大小字段分别对应的信道组。  In the present embodiment, prior agreement BSR control element in a first buffer size field, a second group channel buffer size field, a third and a fourth buffer size field buffer size corresponding to each field.
 例如，事先约定BSR控制元中的第一个缓存大小字段、第二个缓存大小字段、第三个缓存大小字段以及第四缓存大小字段分别对应第一信道组、第二信道组、第三信道组和第四信道组。  For example, a pre-agreed BSR control element in a first buffer size field, the second field cache size, cache size of the third field and the fourth field buffer size correspond to the first channel group and second channel group, a third channel and a fourth channel group set.
