LTE: Can a dedicated bearer contain more than one rating group ?

+1 vote
731 views
  • As per Policy Control and Charging, we can have multiple rules i.e. rule-group mapped to one pcc-action.
  • One pcc-action should have a specific rating-group Id and service-Id and Qos.
  • Since, a dedicated bearer has a fixed Qos, we can say that dedicated bearer is associated with only one pcc-action.
  • According to Gx Spec 29.212, when Rule-Definition is received from PCRF, it comes with rating-group-id, Qos, and Flow-Information to create a dedicated bearer.

So, is it possible that PCRF can send two different rules say RD1 and RD2 with same Qos but different rating-group-id. I dont see this thing mentioned anywhere in 29.212.

Please help with reference to spec...

A dedicated bearer can have multiple rules or let's just say multiple SDF. Each SDF(kind of service) can have its own QoS which in-turn will contribute to bearer QoS. Each SDF can have its own Rating-Group.

So, basically a dedicated bearer can have multiple Rating-Group as in LTE flow based charging happens.
Based on the number of Rating-Group that are mapped to a bearer, the CCR towards OCS will have that many MSCC AVPs on Gy interface.

Dedicated bearer creation QOS relates?

As of now the basic setup for the dedicated bearer works ok (with and without Diameter interface)

As of now, for this initial work, I am trying to see if this can be extended now..Now PCRF just accepts the QCI requested.

Lets say we want to create a new dedicated bearer, then PCRF gets a request saying it needs to create a ded bearer with QOS( QCI=3, Max GBR Ul =10Mbps, MaxGBR Dl=10Mbps, GBR Ul = 5Mbps, GBR Dl=5Mbps.
Lets say this user is assigned, MaxGBRUl =5, MaxGBR Dl=5Mbps, GBR Ul = 2.5Mbps, GBR Dl=2.5Mbps.

What should pcrf do this case ? Allow to create the ded bearer with MaxGBRUl =5, MaxGBR Dl=5Mbps, GBR Ul = 2.5Mbps, GBR Dl=2.5Mbps. ? Or decline to create it ?

Your inputs much appreciated...

PCRF: Dedicated bearer deletion in PGW (PCEF) scenario

Lets say we have a session-0 established for the UE (IPaddress1) for the default bearer. This is when the PGW send the CCRequest(cctype=initial and ccnum=0). Lets say "Policy1" is sent by PCRF in CCA. Does this initial CCRequest has the "Flowdescription" AVP in this ?

Now a dedicated bearer1 is established so CCRequest is sent with (ccrtype =modify and ccnum=1). Lets say PCRF assigns "Policy 2".

Now dedicated bearer 1 is deleted, then what does the PGW send to PCRF ?

Another question: As of now I am storing the list of PolicyRules in PCRF, based on IMSI (IPAddress)..i.e c++ map of IPAddress and PolicyRules. But when the dedicated bearer is removed how do i access the map ? (to find which Policy is deleted)
