What is UMTS-RLCDecoder?

UMTS-RLCDecoder is small but powerful tool for decoding RLC header information both for Acknowledged Mode RLC PDUs and Unacknowledged Mode RLC PDUs.

RLC Unacknowledged Mode (UM) PDU Decoding

UMTS-RLCDecoder can decode:

  • UMD RLC Header information
    • UMD PDU Sequence Number
    • Extension bit
  • Length Indicator Decoding

    Hello Prashant,
    I want to know where is configured the RLC-unacnkokedged, in the Mobile station or the SIM?
    Thanks,
    Best regards,
    NEQB.

  • http://www.3glteinfo.com Prashant

    RLC is always configured in Mobile Station (UE) and in RNC (In NW).

    Thanks for your quick answer,
    Please could you tell me which parameter is configured in the handset.
    Thanks,
    NQ.

    Hi,

    For UM mode and other mode configuration you can refer to RLC Specification. You can get the specification here:

    http://www.3gpp.org/ftp/Specs/latest/Rel-7/25_series/25322-7a0.zip

    Refer to section 4.2.1.2 Unacknowledged mode (UM) RLC entities

    This section describes the general configuration of UM Entity.

    As RLC is configured by RRC (in Layer 3). You can use the RRC specification to know the detail configuration.

    Here is the link to RRC Specification: http://www.3gpp.org/ftp/Specs/latest/Rel-7/25_series/25331-7i0.zip

    In RRC Specification check the section for RRC Connection Setup, Radio Bearer Setup, Radio Bearer Reconfiguration.

    You can also use 3GPP specification 34.108. This describes Common test environments for User Equipment (UE);

    You can get the specification here: http://www.3gpp.org/ftp/Specs/archive/34_series/34.108/34108-710.zip

    hi Author

    in rlc, LI plus extn bit .Where we can use extn bit zero and where we can use extn bit one

    thx

    @surender reddy

    E (Extension Bit)

    E bit tells ”What there in the next field”

    If E = 0 : Next field is data or status PDU or a complete SDUIf E 0 1 : Next filed is Length Indicator (LI) followed by extension bit (E).

    @prashant_3g @surender reddy .can u give one exp plzzz

  • prashant_3g

    @surender reddy Hi, You download the above SW and decode one PDU. You will get detail explanation of each bits of teh RLC header both for AM and UM. FOr example decode this PDU in the decoder program:

    80010BFE01020304050000000000000000000000

    Hi,
     
    Is there any tool to decode UMTS MAC Protocol Header.

  • http://www.3glteinfo.com 3gLteInfo

    Hi,

    I am developing a tool for that but it will take some time as I am overloaded with other things right now.
