NAME SERVICE IN A MULTIHOP WIRELESS AD HOC NETWORK
First Claim
1. A method for handling requests for resources in a packet-switched communications system comprising:
- a terminal arrangement sending an access request to a network element in order to request permission to use communications resources for transmitting a data packet found in a transmission buffer of the terminal arrangement,establishing knowledge about a predicted data packet which is to appear in the transmission buffer of the terminal arrangement, before said predicted data packet appears in the transmission buffer of the terminal arrangement andtransmitting from the terminal arrangement to the network element an access request for predicted traffic, requesting permission to use communications resources for transmitting said predicted data packet once it appears;
wherein transmitting said access request for predicted traffic involves combining said access request for predicted traffic with another transmission.

Abstract
Piggy-backed requests for resources are handled in a packet-switched communications system. A terminal arrangement sends an access request to a network element in order to request permission to use communications resources for transmitting a data packet found in a transmission buffer of the terminal arrangement. Knowledge is established about a predicted data packet which is to appear in the transmission buffer of the terminal arrangement in the near future. The terminal arrangement transmits to the network element an access request for predicted traffic, requesting permission to use communications resources for transmitting said predicted data packet once it appears. This access request for predicted traffic is piggy-backed onto another transmission.
