Abstract
Data packets are received at a communications node. Each of the received data packets is associated with one of a set of different service classes. Packets corresponding to the received data packets are transmitted to recipients. The order in which the data packets are transmitted is controlled based on the transmission rate and the service class of the packets.
Claims33
A method comprising
- receiving data packets at a communications node,
- associating each of the received data packets with a service class and a forward link transmission rate,
- transmitting outbound packets corresponding to the received data packets to recipients, and
- controlling a degree to which an order in which the outbound packets are transmitted to the recipients varies based on:
- (a) the forward link transmission rate associated with each of the received data packets corresponding to the outbound packets,
- (b) the service class associated with each of the received data packets corresponding to the outbound packets, and
- (c) a degree to which an average forwarding percentage for the service class associated with each of the received data packets corresponding to the outbound packets falls below a minimum average forwarding percentage rate assigned to the respective service class.

Apparatus comprising
- a communications node configured to receive data packets, associate each of the received data packets with a service class and a forward link transmission rate, transmit outbound packets corresponding to the received data packets to recipients, and control a degree to which an order in which the outbound packets are transmitted to the recipients varies based on:
- (a) the forward link transmission rate associated with each of the received data packets corresponding to the outbound packets,
- (b) the service class associated with each of the received data packets corresponding to the outbound packets, and
- (c) a degree to which an average forwarding percentage for the service class associated with each of the received data packets corresponding to the outbound packets falls below a minimum average forwarding percentage rate assigned to the respective service class.
1 more element
A method comprising
- receiving from a network operator values representing minimum forwarding performances for each of more than one distinct classes of service associated with transmission of packets from a radio node of a network to recipients, and
- scheduling packets for transmission among the distinct classes, the scheduling being based on a quality of an air-link channel that serves the recipient when the packet is to be transmitted and controlling the variability of a degree to which an order in which the packets are transmitted based on a degree to which a forwarding performance of each of the classes is below forward link transmission rates associated with received data packets corresponding to the outbound packets, service classes associated with the received data packets corresponding to the outbound packets, and the minimum forwarding performance for each of the classes.
