Abstract
A method for multiplexing two data flows on a radio communication channel of a radio communication network, each of the data flows having data packets to be transmitted on the radio communication channel. There are data packets belonging to a first data flow, herein called high priority data flow, and data packets belonging to a second data flow, herein called low priority data flow. In the method, at least one available data packet belonging to the low priority data flow is transmitted if the number of consecutive data packets belonging to the high priority data flow transmitted since the transmission of the latest data packet belonging to the low priority data flow has reached a predefined number of data packets.
Claims11
A method for multiplexing data packets of a high priority data flow and a low priority data flow on a radio communication channel of a radio communication network, said method comprising the steps of:
- transmitting, if available, at least one data packet belonging to said low priority data flow when a number of consecutive data packets belonging to said high priority data flow transmitted since the transmission of a data packet belonging to said low priority data flow has reached a predefined number;
- wherein said predefined number depends on a codec used for coding said low priority data flow, before transmission on said radio communication channel.
A method for multiplexing data packets of a high priority data flow and a low priority data flow on a radio communication channel of a radio communication network, said method comprising the steps of:
- transmitting, if available, at least one data packet belonging to said low priority data flow when a number of consecutive data packets belonging to said high priority data flow transmitted since the last transmission of a data packet belonging to said low priority data flow has reached a predefined number;
- setting a minimum time interval for said step of transmitting available data packets belonging to said low priority data flow,
- wherein said minimum time interval is at least equal to a round trip delay required for one or more data packets belonging to said high priority data flow to be acknowledged at a transmitter by a retransmission protocol.
A transmitter of a radio communication network comprising:
- means for multiplexing at least two data flows, a high priority data flow and a low priority data flow, on a radio communication channel, each of said data flows comprising data packets to be transmitted on said radio communication channel,
- wherein said means for multiplexing at least two data flows comprises:
- means for counting a number of consecutive data packets belonging to said high priority data flow transmitted since transmission of data packet belonging to said low priority data flow;
- means for enabling transmission, if available, of another data packet belonging to said low priority data flow if said number of consecutive data packets belonging to said high priority data flow has reached a predefined number of data packets, wherein said predefined number depends on a codec used for coding said low priority data flow, before transmission on said radio communication channel.
