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.
Claims20
A packet data transmission method, the method comprising receiving a content in the form of packets and dividing said packets into a sequence of sets of packets and for each set of packets in said 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.
A packet data reception method, the method comprising receiving a plurality of transmission bursts, extracting 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, analysing each of said extracted packets and identifying firstly a packet where a change in said first field to a predetermined value is detected and storing this and any subsequent packet with the same first field until such time as a further change in said first field value is detected whereupon reception of transmission bursts is suspended for the time offset identified from said second field value.
