Patent ID: 7978604

Claim:
A method of optimising the bandwidth usage on a Real-Time Protocol managed link transporting media from a Media Resource Function node of a cellular telecommunications network to User Equipment, the method comprising: at the Media Resource Function node, monitoring the rate of packet loss of the link to determine whether the rate of packet loss is unacceptably high or within acceptable limits; and as a result of said monitoring, adapting the sending rate from at the Media Resource Function node over the link to the User Equipment by re-packetising media, received at the Media Resource Function node from third party nodes, to either increase the size of packets sent over the link when the rate of packet loss is unacceptably high, thereby reducing packet header overhead and reducing bandwidth usage on the link; or to decrease the size of packets sent over the link when the rate of packet loss is within acceptable limits, thereby reducing the transmission delay over the link.
