Patent ID: 8854970

Claim:
A method in a first communication network node that uses a scheduler buffer for a given user equipment communicating with said first communication network node, said first communication network node comprising a flow control entity, the method comprising the steps of: controlling by the flow control entity the flow of data in respect of a given mobile terminal between a second communication network node and said first communication network node in a communication network system; generating a capability allocation message, used for controlling the flow of data in respect of said given mobile terminal between said second communication network node and said first communication network node in said communication network system, based on a first compensation factor that is determined based on at least one of: scheduling policy, mobility, load and radio channel type; and setting said first compensation factor as a value greater than 1 when using scheduling polices configured as proportional fairness (PF) scheduling or maximum Channel Quality Indicator (maxCQI) scheduling to control the flow of data for the given mobile terminal, and setting said first compensation factor as a value smaller than 1 when using scheduling polices configured as Round Robin (RR) scheduling, wherein generating the capability allocation message comprises determining a previous value of a capability allocation and multiplying the previous value of the capability allocation with said first compensation factor.
