Description (partial)

Scenario :
1. 3G call on gngp setup, custom40 dictionary
2.Bring up a 3G call
3. from Gx send revalidation timeout trigger and initial QoS as 8,1,1,0 and AMBR UL and DL as 86400000
4. send data ( icmp - 5ping packets).
5. after revaildation time expires, ggsn sends a CCR-U to Gx. In CCA-U , Gx sends the following :
 [V] [M] QoS-Information:
          [V] APN-Aggregate-Max-Bitrate-UL: 8000
          [V] APN-Aggregate-Max-Bitrate-DL: 8000
        [V] Default-EPS-Bearer-QoS:
          [V] [M] QoS-Class-Identifier: QCI_3 (3)
          [V] [M] Allocation-Retention-Priority:
            [V] [M] Priority-Level: 1
            [V] [M] Pre-emption-Capability: PRE-EMPTION_CAPABILITY_DISABLED (1)
            [V] [M] Pre-emption-Vulnerability: PRE-EMPTION_VULNERABILITY_ENABLED (0)

6. send data again.
7. Clear the call.

Now , that the bearer is a GBR bearer, in the PGWCDR, the mbr values cannot be 0 for it. However, I am seeing the following :

   qCI                                  3
     maxRequestedBandwithUL               0 <<<< issue
     maxRequestedBandwithDL               0 <<< issue
     guaranteedBitrateUL                  0
     guaranteedBitrateDL                  0
     aRP                                  68
