    Clear Definition For Channel element
    “A band Channel Element is the resource base required in the Node-B to Provide for one voice channel capacity, including the control plane to Provide for one voice channel capacity, including the control plane signaling, compressed mode, the transmit diversity and softer handover. “signaling, compressed mode, the transmit diversity and softer handover.”

    Factors affecting capacity in WCDMA UL and DL, sorted by descending level of importance as follows: Factors affecting Capacity in WCDMA UL and DL, sorted by descending level of Importance as Follows:
    – UL: No. CE support on each Node B, interference, Node B sensivity, .. – UL: No. CE support on the each Node B, interference, Node B sensivity, ..
    – DL: No. CE support on each Node B Iub interface capacity, power DL, OVSF, … – DL: No. CE support on the each Node B Iub interface capacity, power DL, OVSF, …

    Thus, CE can be viewed as a license for each NodeB capacity (not more). Thus, CE can be viewed as a license for each vertex NodeB capacity (not more).
    Each service will need some different CE UL and DL, such as: the each service will need some Different CE UL and DL, such as:
    AMR 12.2 k: Uplink 1; downlink AMR 12.2 k 1: Uplink 1; downlink 1
    CS / PS 64 K: 3 Uplink, downlink 2 CS / PS 64 K: 3 Uplink, downlink 2
    PS 128/144k: Uplink 5; downlink 128/144k PS 4: Uplink 5; DL 4
    384 k PS: Uplink 10, downlink 8384 k PS: Uplink 10; downlink 8

    in the license etch Node B The channels elements config is UL:272 /DL:48

    – i have a congestion for the ps DL/UP channels elements, the HSUP
    and the HASDP function normal no congestion.

    please can some one answer me about the resolution off this problem

    Traffic Model

    AMR12.2 (Erl) 0.035 0.035
    CS64 (Erl) 0.000 0.000
    PS64 (kbit) 144.00 96.00
    PS128 (kbit) 0.00 192.00
    PS384 (kbit) 0.00 288.00
    HSPA (kbit) 576.00 2304.00
    Total 720.00 2880.00

    Assumptions
    Subscriber per site (S111) is 586
    SHO overhead 20%
    Retransmission for PS 1%
    Burst Ratio 40%

    Traffic of voice
    0.035*586*(1+20%) = 24.612 Erl
    GoS=2% do =33 Erl

    CE for voice peak traffic
    33 * 1=33 CE

    CE for UL R99 PS64k
    ((144*586)/(64*0.2*3600))*3*(1 20%)*(1 1%)*(1 40%) = 10CE

    Same you can calculate for other RAB Services and HSUPA.

    Thanks

    Hello

    Any idea about the 2 Below Radio KPI

    – Average uplink CE congestion rate
    – Power Congestion

    • Which input to use
    • Any Measurement Protocol
    • Minimum Level
    • Formula to use

    Many Thanks for your support

    Dear

    Last line means you have PS64, PS128, PS384 and HSUPA so you can calculate the CE.

    Thanks

    Hello friend…Are the SHO overhead, Burst ratio, retransmission for PS and the formula to calculate CE is vendor dependent or it is a standard values.??

    Hi Hussain, Please explain this forumal again for other services
    CE for UL R99 PS64k
    ((144*586)/(64*0.2*3600))*3*(1 20%)*(1 1%)*(1 40%) = 10CE..

    Thanks in advance
