Packet data transmission in third generation mobile system
View Patent ↗In an aspect, an apparatus is provided including a mapping device configured to establish mapping information for delivery order attributes corresponding to different transmission protocol types, and a detection device configured to detect a transmission protocol type for the transmission of data packets. The apparatus further includes a decision device configured to decide whether the detected protocol type is a predetermined type, and a setting device configured to set, based on the mapping information and the decision result, a delivery order attribute as a parameter for transmission of data packets in a packet data network if the predetermined protocol type is not present.
1. An apparatus comprising:
a mapping device configured to establish mapping information for delivery order attributes corresponding to different transmission protocol types;
a detection device configured to detect a transmission protocol type for the transmission of data packets;
a decision device configured to decide whether said detected protocol type is a predetermined type; and
a setting device configured to set, based on said mapping information and said decision result, a delivery order attribute as a parameter for transmission of data packets in a packet data network if the predetermined protocol type is not present.
2. The apparatus of claim 1 , wherein the delivery order attribute indicates that the order of transmitted data packets is to be maintained.
3. The apparatus of claim 1 , wherein the setting device is configured not to set the delivery order attribute if the predetermined protocol type is present.
4. The apparatus of claim 3 , wherein an unset delivery order attribute indicates that the order of transmitted data packets does not need to be maintained.
5. The apparatus of claim 1 , wherein said predetermined protocol type comprises a protocol type used for real-time transmission.
6. The apparatus of claim 1 , wherein said transmission protocol type is derived from packet data protocol (PDP) context information or packet data protocol (PDP) type information.
7. The apparatus of claim 1 , wherein the apparatus comprises a terminal.
8. The apparatus of claim 1 , wherein the apparatus comprises a network element.
9. An apparatus comprising:
means for establishing mapping information for delivery order attributes corresponding to different transmission protocol types;
means for detecting a transmission protocol type for the transmission of data packets;
means for deciding whether said detected protocol type is a predetermined type; and
means for setting, based on said mapping information and said decision result, a delivery order attribute as a parameter for transmission of data packets in a packet data network if the predetermined protocol type is not present, wherein said apparatus is implemented on at least one of a network node or a terminal.
