Deletion request after number of failed acknowledgements to addition requests

Abstract

Network circuitry and a method of operating the same in establishing and deleting a service flow in a wireless network. A network station receives a request, from an initiating network station, to establish a service flow. The network station receiving the request issues a response to that request, following which it expects an acknowledgement from the initiator. Upon absence of such an acknowledgement, the receiving station transmits a message, to the initiator, to explicitly delete the service flow. This ensures that the initiator is not placed into an ambiguous state of transmitting payload traffic to a receiver that is ignoring or not receiving that traffic, in the case in which the initiator is also the transmitter of the payload traffic. This circuitry and method also ensures that the initiator is not in an ambiguous state, in the case in which it is the intended receiver of the payload traffic.
