BandWidth fields represent the bandwidth threshold of current physical port；Here, according to the regulation of 3GPP agreements, physical port institute
The protocol type of carrying is divided into IP carryings and asynchronous transfer mode (ATM, Asychronous Transfer Mode) carrying two
Kind；Wherein, carry for IP, held for IMA groups etc. for the physical port of MLPPP link groups and ethernet link, bearer types
The physical port of ATM agreements is carried, bearer types carry for ATM；TransportLayerAddress fields are tied up by physical port
Fixed transmission network layer address is RNC with the identifiable 3GPP agreements in base station as defined in dock parameter, if bearer types are
IP is carried, i.e., the implication of Physical port type fields carries for IP, then TransportLayerAddress fields carry
Be：The IP address of IUB interfaces bound in the physical port of base station, if bearer types carry for ATM, i.e.,：Physical
The implication of port type fields carries for ATM, then what TransportLayerAddress fields carried is：Base station side is corresponding
The atm port atm adaptation layer 2 that such as IMA groups port has under its command (AAL2, ATM Adaptation Layer 2) ID of trace route path
(PATH ID)。
Step 203：After RNC receives Audit Response message, decoded from the Audit Response message
OPTIONAL IE, by the bandwidth threshold of each physical port in OPTIONAL IE and corresponding preconfigured bandwidth threshold
It is compared, if it is larger than or equal to then performing step 205, otherwise, performing step 204；
Here, by the bandwidth threshold of each physical port in OPTIONAL IE and corresponding preconfigured bandwidth door
When limit is compared, RNC matches the IUB interfaces of the port association according to the implication of TransportLayerAddress fields

Step 204：The CAC of IUB interface downlinks and the bandwidth threshold of flow control that RNC currently preserves itself are updated to
The bandwidth threshold of the physical port reported, performs step 205 afterwards；
Step 205：The CAC of IUB interface downlinks and the bandwidth threshold of flow control that RNC is currently preserved according to itself, it is real
CAC and flow control are applied, it is accurate to distribute and use transmission bandwidth resource, terminate currently processed flow afterwards；
Here, if RNC determines bandwidth threshold of the bandwidth threshold less than or equal to the physical port reported of the configuration,
The CAC of the IUB interface downlinks itself currently preserved and the bandwidth threshold of flow control are preconfigured bandwidth threshold.
If RNC has found that the bandwidth threshold after renewal is more than previously stored bandwidth threshold, newly-increased richness is made full use of
Remaining bandwidth resources, allow more service accesses in busy, scheduling amount of the appropriate increase in line service in flow control；Such as
Fruit RNC has found that the bandwidth threshold after renewal is less than previously stored bandwidth threshold, then the strictly access of control follow-up business so that
Actual bandwidth reserves amount without departing from current thresholding in admission control, while in IUB interface downlink flow controls, tightening pair
