Packet delivery method for use in a wireless local area network (LAN)
First Claim
1. A packet delivery method for assuring the delivery of packets in an wireless local area network (LAN) having a service access point (AP) and a plurality mobile user devices (UDs), said user devices in communication with each other and with the access point, said method comprising the steps of:
- receiving, at the AP, a transmission comprising data from a source user device and destined for a destination user device;
determining whether the source device is requesting the AP to deliver data to the destination device; and
, if so, inhibiting transmission from the source device of further data associated with the data while;
delivering the data to the destination user device;
receiving an acknowledgment from the destination user device;
informing the source user device of delivery of the data to the destination user device; and
permitting the source device to thereafter transmit data to the destination device.

Abstract
A packet delivery method for assuring the delivery of packets in an wireless local area network (LAN) having a service access point (AP) and a plurality mobile user devices, said user devices in communication with each other and with the access point. The access point determines when a destination device is in the sleep mode of operation and stores data packets intended for that device in memory. Thereafter the access point determines when the destination device enters the active mode of operation, delivers the data packets to the destination device and informs the source device of delivery of the data packets to the destination device.

9. A packet delivery method for assuring the delivery of packets in an wireless local area network (LAN) having a service access point (AP) and a plurality mobile user devices (UDs), said user devices in communication with each other and with the access point, said method comprising the steps of:
-
receiving, at the AP, a transmission comprising data from a source user device and destined for a destination user device, the transmission selectively comprising a request indicating whether the source device is requesting the AP to deliver data to the destination device; determining from the transmission whether the source device is requesting the AP to deliver data to the destination device; and
, if so, inhibiting transmission from the source device of further data associated with the data while;determining whether the destination user device is in a sleep mode of operation; if true, then, storing the data in memory; waiting until the destination user device is active; delivering the data to the destination user device; receiving an acknowledgment from the destination user device; and informing the source user device of delivery of the data to the destination user device.
