Method of performing a layer operation in a communications network
View Patent ↗In an embodiment of the present invention, a scheduling operation is performed at a lower layer based on upper layer information. In another embodiment of the present invention, an action is performed at an upper layer based on received lower layer information. Also, a scheduling operation may be performed on at least one upper layer data packet at a lower layer based on a lower layer analysis of the upper layer data packet.
1. A method of managing data communication in a wireless network, comprising:
acquiring, at an upper layer process of a processor of a network element, a time stamp associated with an upper layer data packet to be sent to a lower layer;
analyzing, at the lower layer process of the network element, the time stamp associated with the upper layer data packet;
changing, at the lower layer process of the network element, a priority of the upper layer data packet based on the time stamp received from the upper layer, the changing of the priority of the upper layer data packet being one of delaying or advancing transmission of the upper layer data packet based on a comparison of the time stamp to a timing threshold, the time stamp being a delivery deadline,
wherein an upper layer associated with the received upper layer information handles at least one of Internet Protocol (IP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), Real-time Transport Protocol (RTP) and Voice Over Internet Protocol (VoIP) protocols,
wherein the lower layer handles at least one of Hybrid Automatic Repeat Request (ARQ), Acknowledged Radio Link Control (AM-RLC), Radio Link Control-Unacknowledged Mode Radio Link Control (UM-RLC), Media Access Control (MAC) and High Speed Downlink Packet Access (HSDPA) protocols.
2. The method of claim 1 , wherein the priority of the upper layer data packet is decreased if the time stamp is earlier than the timing threshold and has not expired.
3. The method of claim 1 , wherein the priority of the upper layer data packet is increased if the time stamp is later than the timing threshold and has not expired.
4. A method of managing data communication in a wireless network, comprising:
changing, at a lower layer process of a network element, a priority of a data packet at the lower layer by comparing received upper layer information against a timing threshold, wherein the upper layer information is a time stamp in an upper layer data packet, the time stamp being a delivery deadline,
wherein an upper layer associated with the received upper layer information handles at least one of Internet Protocol (IP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), Real-time Transport Protocol (RTP) and Voice Over Internet Protocol (VoIP) protocols,
wherein the lower layer handles at least one of Hybrid Automatic Repeat Request (ARQ), Acknowledged Radio Link Control (AM-RLC), Radio Link Control-Unacknowledged Mode Radio Link Control (UM-RLC), Media Access Control (MAC) and High Speed Downlink Packet Access (HSDPA) protocols.
5. The method of claim 4 , wherein the priority of the upper layer data packet is decreased if the time stamp is earlier than the timing threshold and has not expired.
6. The method of claim 4 , wherein the priority of the upper layer data packet is increased if the time stamp is later than the timing threshold and has not expired.
7. A method of managing data communication in a wireless network, comprising:
changing, at a lower layer process of a network element, a priority on at least one upper layer data packet based on a lower layer analysis of the at least one upper layer data packet, wherein the lower layer analysis includes comparing a time stamp associated with the at least one upper layer data packet against a timing threshold, the time stamp being a delivery deadline,
wherein an upper layer associated with the received upper layer information handles at least one of Internet Protocol (IP), User Datagram Protocol (UDP), Transmission Control Protocol (TCP), Real-time Transport Protocol (RTP) and Voice Over Internet Protocol (VoIP) protocols,
wherein the lower layer handles at least one of Hybrid Automatic Repeat Request (ARQ), Acknowledged Radio Link Control (AM-RLC), Radio Link Control—Unacknowledged Mode Radio Link Control (UM-RLC), Media Access Control (MAC) and High Speed Downlink Packet Access (HSDPA) protocols.
