SYSTEM AND METHOD FOR IDENTIFYING DATA

摘要

The present invention discloses a system and a method for identifying data, which relates to the field of data transmission. The system comprises a transmitting end and a receiving end, the receiving end comprises a data receiving unit, a first field determining unit, a second field determining unit, identification unit, the method comprises: receiving a PDU with the first one and the second one of length indication fields transmitted by the transmitting end; analyzing and determining whether the value of the second one of length indication fields is equal to a first preset value; if the above two judgments are success, then the corresponding PDU data pack would be identified as valid. The positive effects of the above technical schemes are: remedying the defect of the protocol in that the descriptions of the PDU package with the upstream construction and the PDU package with the downstream reconstruction are inconsistent.

主权项

1. A system for identifying data, comprising:
a transmitting end, a receiving end, a PDU (Protocol Data Unit) related to an unacknowledgement mode data, the transmitting end transmitting a PDU with a first identification and a second identification to the receiving end through a communication network; the receiving end comprising: a data receiving unit for receiving the PDU; a second field determining unit connecting the data receiving unit for determining whether the value of the second identification is equal to a first preset value, and thereby outputting a corresponding first determining result; a first field determining unit connecting the second field determining unit, the first field determining unit comprising a second preset value configured for determining whether the received value of the first identification is equal to the first preset value when the value of the second identification is equal to the first preset value, based on the first determining result, and thereby outputting a corresponding second determining result; and an identifying unit connecting the first field determining unit, the identifying unit being configured for based on the first determining result and the second determining result, identifying the corresponding PDU as a valid data package when value of the second identification equal to value of the first preset value and the value of the first identification being equal to the second preset value.
