Abstract
A policy caching method for use in a communication device is provided. The communication device determines which instance of protocol data unit (PDU) network policy from a plurality of policies is to be applied to related-received PDUs based on contents of one of the related-received PDUs. Subsequently, policy identification information identifying the instance PDU policy is cached for future application to other of the related-received PDUs. Also, a communication device which implemented this policy caching method is provided.
