Abstract
In the present invention, before data transmission, a “connection”, between a requesting end and a destination end, identified by a traffic flow identifier (FID) is established or modified through traffic flow management. Therefore, when the requesting end and the destination end perform data transmission on the traffic flow, the FID alone can sufficiently serve as the identifier, so as to save the need of carrying the destination end identifier in each exchanged data packet, thereby simplifying the operation.
Claims12
A traffic flow establishing method comprising:
- Send/Receive dynamic service establishing request with destination identifier and traffic flow identifier (FID);
- and
- Receive/Send response to dynamic service establishing request,
- wherein the dynamic service establishing request carries FID maximum buffer capability, and indicates a number of Mac Protocol Data Units (“MPDUs”) of the dynamic service establishing request with maximum cache at the receiving end.
A traffic flow changing method, comprising:
- sending dynamic service change request with destination identifier, traffic flow identifier (FID) and new service parameters;
- receiving response to dynamic service change request,
- wherein the dynamic service change request carries FID maximum buffer capability, and indicates a number of Mac Protocol Data Units (“MPDUs”) of the dynamic service change request with maximum cache at the receiving end.
A traffic flow establishing device comprising:
- request sending unit, which sends dynamic service establishing request carrying destination identifier and traffic flow identifier (“FID”);
- response receiving unit, which receives the response to the dynamic service establishing request;
- direction information provision unit and/or buffer capacity provision unit;
- wherein the direction information provision unit is used to send the information that indicates the direction of uplink or downlink traffic flows to be created to the request sending unit, which will be sent with dynamic service establishing request;
- and
- the buffer capacity provision unit is used to provide FID maximum buffer capability to the request sending unit, which will be further sent with dynamic service establishing request, and the FID maximum buffer capability indicates a number of Mac Protocol Data Units (“MPDUs”) of the dynamic service establishing request with maximum cache at the receiving end.
A traffic flow change device comprising:
- request sending unit, which sends dynamic service change request carrying destination identifier, traffic flow identifier FID and new service parameters;
- response receiving unit, which receives the response to the dynamic service change request;
- direction information provision unit and/or buffer capacity provision unit;
- wherein the direction information provision unit is used to send the information that indicates the direction of uplink or downlink traffic flows to be changed to the request sending unit, which will be sent with dynamic service change request;
- and
- the buffer capacity provision unit is used to provide FID maximum buffer capability to the request sending unit, which will be further sent with dynamic service change request, and the FID maximum buffer capability indicates a number of Mac Protocol Data Units (“MPDUs”) of the dynamic service change request with maximum cache at the receiving end.
