Abstract:
1. A communications method for use in a communications system including an access node and at least one mobile node, a communications path extending between said at least one mobile node and said access node, said communications path including a wireless communications link, the communications system further including a first network node coupled to said access node by an access link and a second network node coupled to said first network node, a first packet tunnel extending between said second network node and one of said access node and said mobile node, said first packet tunnel passing through said first network node and over said access link, said first packet tunnel being used to communicate at least one packet tunnel constituent packet flow, the method comprising: storing packet classification information in said access node, said packet classification information including: i) information used to identify packets corresponding to said first packet tunnel, ii) information used to identify packets corresponding to a first access link packet aggregate, and iii) information defining a mapping between packet tunnels and access link aggregates to be used for routing packets between said packet tunnels and said access link aggregates, said information including information indicating a mapping between said first packet tunnel and said first access link packet aggregate; and operating the access node to communicate said packet classification information to the first network node.
