Abstract
A method and apparatus for determining the transmission time of packets of information in a communication system includes a temporal offset processor (330) which receives transmission delay information from a delay analyzer (315) and soft handoff state information from a control processor (320). This information is used to determine a temporal offset for packets of information. The temporal offset is used by a network arbiter (350) to determine when the associated packet should be transferred in time.
Claims28
A method for determining a time of transmission of packets of information in a communication system, comprising the steps of:
- receiving a first packet of information associated with a communication between a first mobile unit and a first base site transmitter and a second base site transmitter;
- comparing a transmission delay associated with the first base site transmitter and a transmission delay associated with the second base site transmitter;
- receiving additional packets of information at a network arbiter;
- and
- determining an estimate of the time of transmission of the first packet and the additional packets based, at least in part, on the comparison,
- wherein the additional packets of information are associated with independent communications between additional mobile units and at least the first base site transmitter, and
- wherein the step of determining the estimate of the time of transmission comprises the steps of
- determining a plurality of differences between a transmission delay associated with the first base site transmitter and the transmission delays associated with a plurality of further base site transmitters, and
- determining the estimate of the time of transmission of the first packet and the additional packets based, at least in part, on the plurality of differences.
A system for determining a time of transmission of packets of information in a communication system comprising:
- means for receiving a plurality of packets of information;
- means for comparing a transmission delay associated with a first base site transmitter and a transmission delay associated with a second base transmitter;
- and
- means for determining an estimate of the time of transmission of the plurality of packets based, at least in part on the comparison.
A system for determining a time of transmission of packets of information in a communication system comprising:
- means for receiving a plurality of packets of information;
- means for determining a type of information contained in the plurality of packets of information;
- means for comparing a transmission delay associated with a first base site transmitter and a transmission delay associated with a second base transmitter;
- and
- means for determining an estimate of a time of transmission of the plurality of packets based on the comparison and the type of information.
