    • Apparatus, computer program products and methods allow inclusion and segmentation of multiple SDUs within a PDU, and generate information (such as header information) necessary to identify, e.g., the position of the segmented SDUs within the PDU. Prior knowledge of the typically used (i.e., predetermined) SDU size is used to perform segmentation operations, hi one exemplary variant, apparatus, methods and computer program products determine if a particular one of a set of input data units (SDUs) is to be segmented in order to fit a portion of the set, including a segment of the particular input data unit, into an output data unit (PDU); segment the input data unit in response to determining the particular input data unit is to be segmented; add the portion of the set to a data portion of the output data unit, and add into the output data unit an indication of a position of the segment in the data portion. In another variant, apparatus, computer program products and methods receive first data units, each of the first data units including a plurality of data portions having a plurality of second data units, each of at least two of the first data units including an indication of a position of a segment of a second data unit in associated ones of the data portions; combine using at least the indications the segments to create a complete second data unit; and output the complete second data unit.
    • 装置,计算机程序产品和方法允许在PDU内部包含和分割多个SDU,并生成识别例如PDU内的分段SDU的位置所需的信息(诸如标题信息)。 使用通常使用(即,预定)SDU大小的先前知识来执行分割操作。在一个示例性变型中,装置,方法和计算机程序产品确定一组输入数据单元(SDU)中的特定一个是否是 分段以便将包括特定输入数据单元的段的组的一部分适配成输出数据单元(PDU); 响应于确定特定输入数据单元被分段而对输入数据单元进行分段; 将集合的部分添加到输出数据单元的数据部分,并在输出数据单元中添加数据部分中的段的位置的指示。 在另一变型中,装置,计算机程序产品和方法接收第一数据单元,每个第一数据单元包括具有多个第二数据单元的多个数据部分,第一数据单元中的至少两个数据单元包括 在相关联的数据部分中的第二数据单元的段的位置; 组合使用至少指示段来创建完整的第二数据单元; 并输出完整的第二数据单元。
