Abstract
A method and apparatus are disclosed whereby a time-slicing approach to the delivery of packet data is enabled. The approach is particularly suited to enabling power management by mobile terminals where receiver demands otherwise place strenuous requirements on an internal power source such as a battery.
Claims28
A computer implemented method comprising:
- receiving content in the form of packets, and
- dividing, by a computer, the packets into a sequence of sets of packets comprising a sequence of sets of original packets,
- for each set of packets in the sequence, generating a transmission burst, wherein a field in each packet of a set includes a value indicative of a time offset to the generation of a further transmission burst containing a next set of packets in the sequence,
- generating a copy of a set of original packets, and
- generating at least one transmission burst for said copy, wherein a field in each packet of said copy includes a value indicative of a time offset to the generation of a further transmission burst containing a next of original packets in the sequence.
2 more elements
An apparatus comprising:
- a processor configured to
- receive content in the form of packets, and
- divide the packets into a sequence of sets of packets comprising a sequence of sets of original packets, and
- generate a copy of a set of original packets of said sequence of sets of original packets;
- and
- a burst generator configured to:
- generate a transmission burst for each set of packets in the sequence,
- wherein a field in each packet of a set includes a value indicative of a time offset to the generation of a further transmission burst containing a next set of packets in the sequence, and
- generate at least one transmission burst for said copy, wherein a field in each packet of said copy includes a value indicative of a time offset to the generation of a further transmission burst containing a next set of original packets in the sequence.
6 more elements
A computer implemented method comprising:
- receiving a plurality of transmission bursts,
- extracting, by a computer, a set of packets from each burst, each packet including a first field having a value indicative of a sequence of sets of packets and a second field indicative of a time offset to the generation of a transmission burst containing a next set of packets in the sequence,
- analyzing, by the computer, each of the extracted packets,
- identifying first a packet where a change in the first field to a predetermined value is detected and storing the packet and any subsequent packet with a same first field until such time as a further change in the first field value is detected whereupon reception of transmission bursts is suspended for the time offset identified from the second field value wherein the plurality of transmission bursts comprise transmission bursts corresponding to sets of original packets and transmission bursts corresponding to copies of sets of original packets, and the sequence of sets of packets comprises a sequence of sets of original packets such that the second field is indicative of a time offset to the generation of a transmission burst containing a next set of original packets.
1 more element
An apparatus comprising:
- a receiver configured to
- receive a plurality of transmission bursts, and
- extract a set of packets from each burst, each packet including a first field having a value indicative of a sequence of sets of packets and a second field indicative of a time offset to the generation of a transmission burst containing a next set of packets in the sequence;
- and
- a controller configured to
- analyze each of the extracted packets, and
- identify a packet where a change in the first field to a predetermined value is detected, and
- store the packet and any subsequent packet with a same first field until such time as a further change in the first field value is detected whereupon reception of transmission bursts is suspended for the time offset identified from the second field value, wherein the plurality of transmission bursts comprise transmission bursts corresponding to sets of original packets and transmission bursts corresponding to copies of sets of original packets, and the sequence of sets of packets comprises a sequence of sets of original packets such that the second field is indicative of a time offset to the generation of a transmission burst containing a next set of original packets.
