Rate, RTVR) Business Stream, for supporting the real time service stream of transmission periodically elongated packet, example
Such as mpeg video stream；Non-Real-time polling service (Non-Real-Time Variable-Rate, NRTVR)
Business Stream, has minimum data rate requirement, data packet length variable and insensitive to time delay for support
Service flow, such as ftp business；The service of doing one's best (Best Effort, BE) Business Stream, is used for supporting
Without business such as the service flow of minimum data rate requirement, such as Internet；Extended real time polling services
(Extended Real-Time Variable Rate, ERTVR) Business Stream, is used for supporting that bandwidth is dynamic
VoIP business etc. with the real time business of variable-length, such as band silence compression.Wherein, UGS business
Stream, ERTVR Business Stream and RTVR Business Stream are real time business stream, it is provided that QoS guarantee be maximum
Supporting rate, minimum reserved rate, maximum tolerance time delay and maximum tolerance delay variation；NRTVR business
Stream is for non-real-time service stream, it is provided that QoS guarantee be minimum supporting rate；BE Business Stream is also non-solid
Time Business Stream, the guarantee of any QoS is not provided.

The new service flow minimum reserved rate ensured；
Step 102: if the new service flow minimum reserved rate that BS be can guarantee that reaches new service flow and carries
Minimum reserved rate parameter, then BS receives this Business Stream, otherwise excludes this Business Stream.
There are the following problems for existing call access control implementation method:
1) due to the transmutability of wireless link channel quality, the number that under high-order modulating, every Slot can carry
The data word joint number that every Slot can carry it is greater than under low-order-modulated mode according to byte number；At high-order
The data word joint number that 5/6 time every Slot of 64QAM can carry is most, at lowest-order QPSK (Quadrature
Phase Shift Keying, QPSK) data word joint number that 1/2 time every Slot can carry is minimum.
So, under identical available Slot number, the minimum of the new service flow received under high-order modulating
Reserved rate will can guarantee that in low-order-modulated mode the most again.
2) for descending real time business stream, the scheduling of BS is except needing to ensure the minimum guarantor of this Business Stream
Stay outside speed, in addition it is also necessary to ensure maximum tolerance time delay and the maximum tolerance delay variation of this Business Stream, otherwise
The scheduling of BS will dropping packets.Therefore, BS receives new descending real time business stream also to need to consider packet loss
Rate.
3) for descending BE Business Stream, although the scheduling of BS has any QOS to ensure, but also has
The restriction of minimum scheduling interval, otherwise the general of the data on BE Business Stream all the time cannot be by BS in transmission of eating dishes without rice or wine
To MS.Therefore, BS receives new descending BE Business Stream to also need to consider minimum scheduling interval.
