Abstract:
1. A method in a network node for admission control of broadcast transmission sessions in a broadcast transmission area, the method comprising: receiving a broadcast transmission session start request for a first broadcast transmission session, obtaining at least a first traffic statistics parameter related to said first broadcast transmission session, obtaining an available bit rate for the broadcast transmission area, obtaining a re-synchronization parameter indicating a time between re-synchronization of transmissions for said first broadcast transmission session, calculating a first expected bit error rate based on said at least first traffic statistics parameter, said available bit rate and said re-synchronization parameter, wherein said first expected bit error rate is calculated by estimating an average number of bits remaining in a transmit buffer for said first broadcast transmission session at re-synchronization using said at least first traffic statistics parameter and dividing by an estimated number of transmitted bits for said first broadcast transmission session during the time between re-synchronization, and admitting said first broadcast transmission session if said first expected bit error rate is less than a first bit error rate threshold.
