Abstract:
1. A method in a first network node, the first network node being one of: i) a policy and charging rules function (PCRF) node, ii) a packet data network gateway (PGW), and iii) a gateway general packet radio service support node (GGSN), the method comprising: receiving, at the first network node, a trigger message transmitted by a second network node, the trigger message comprising a first user equipment aggregated maximum bit rate (UE-AMBR) and a first rank value (r1) indicating a rank of a second network node; in response to the trigger message, the first network node: i) obtaining a second rank value (r2) indicating a rank of the first network node, ii) comparing r2 against r1, iii) determining that r2 is greater than r1; and iv) in response to determining that r2 is greater than r1, selecting an authorized UE-AMBR that is different than said first UE-AMBR; and transmitting, from the first network node to the second network node, a response message comprising the selected authorized UE-AMBR and r2.
