Method of dynamically allocating time slots on a packet data communications channel
First Claim
1. In a packet data communications system including a fixed network and user terminals, the system using a channel organized into time slots for scheduling data communications between the network and the user terminals, a method of dynamically allocating active time slots for a terminal including the steps of:
- communicating, from the terminal, information identifying an active time slot pattern having a pattern key and a time slot identifier for the terminal to the network, the active time slot pattern defining a pattern of active time slots, during which the terminal is active to receive data being sent by the network to the terminal, and inactive time slots, during which the terminal is inactive so as not to receive data from the network; and
entering, at the terminal, an active mode during each active time slot of said active time slot pattern.

Abstract
A method of dynamically allocating active time slots for a terminal (103) that is operating in a packet data communications system (100) which includes a fixed network (101) and user terminals (103), the system using a channel organized into time slots for scheduling data communications between the network and the user terminals, the method including first communicating information, further including a terminal ID and a packet key, representative of an active time slot pattern for the user terminal to the network; and second entering, at the user terminal, an active mode during each active time slot of the active time slot pattern.

11. In a packet data communications system including a fixed network and user terminals, the system using a channel organized into time slots for scheduling data communications between the network and the user terminals, a method of dynamically scheduling message delivery to a terminal including the steps of:
-
receiving information identifying an active time slot pattern having a pattern key and a time slot identifier from the terminal, the active time slot pattern defining a pattern of active time slots, during which the terminal is active to receive data being sent by the network to the terminal, and inactive time slots, during which the terminal is inactive so as not to receive data from the network; queuing a message intended for delivery to the terminal; determining, dependent on said information, said active time slot pattern for the terminal; and delivering said message to the terminal during an active time slot of said active time slot pattern. - View Dependent Claims (12, 13, 14, 15, 16)
