Method for implementing data segmentation and concatenation and reassembly and transmitter thereof
First Claim
1. A method for data segmentation and concatenation, comprising:
- deciding whether the type of Service Data Unit (SDU) information to be encapsulated in a first Protocol Data Unit (PDU) is consistent with the type of SDU information already encapsulated in the first PDU and, if consistent, encapsulating the SDU information to be encapsulated in the first PDU for transmission;
if not consistent, encapsulating the SDU information to be encapsulated in a second PDU for transmission.

Abstract
A method for data segmentation and concatenation, including the steps of: first deciding whether the type of Service Data Unit (SDU) information to be encapsulated in a Protocol Data Unit (PDU) is identical consistent with the type of SDU information already encapsulated in the PDU, if consistent, encapsulating the SDU information to be encapsulated in the PDU for transmission; if not consistent, encapsulating the SDU information to be encapsulated in a second PDU for transmission. A method for data reassembly and a transmitter are disclosed as well. By the method for data segmentation and concatenation, the method for data reassembly, and the transmitter, it is possible to avoid unnecessary duplicated reassembly, preventing the receiver from reassembling the data that may lead to errors and improving the reliability of information transmission.

16. A method for data reassembly, comprising:
deciding whether a Service Data Unit (SDU) segment in a first Protocol Data Unit (PDU) containing an end indicator of SDU has been reassembled and, if the SDU segment in the first PDU containing an end indicator has been reassembled, conducting no reassembly of the SDU segment in the first PDU containing the end indicator of SDU. - View Dependent Claims (17, 18, 19)

20. A transmitter, comprising:
-
a transmission buffer for saving SDUs;
an add RLC header unit for appending an RLC header to a first PDU to be sent; and
a segmentation and concatenation unit for conducting segmentation and concatenation of received SDUs in accordance with the principle of encapsulating different types of SDU information into different PDUs for transmission, and assembling the SDU into PDUs. - View Dependent Claims (21)
