AIR INTERFACE FOR FIXED BROADBAND WIRELESS ACCESS SYSTEMS

IEEE Std 802.16-2001

11.4.8.3 Service Class Name

The value of this field refers to a predefined BS service configuration to be used for this service flow.

Type

Value

Scope

 

 

 

 

[24/25].4

2 to 16

Zero-terminated string of ASCII characters.

DSx-REQ

 

 

 

DSx-RSP

 

 

 

DSx-ACK

 

 

 

 

NOTE—The length includes the terminating zero.

When the Service Class Name is used in a service flow encoding, it indicates that all the unspecified QoS Parameters of the service flow need to be provided by the BS. It is up to the operator to synchronize the definition of Service Class Names in the BS and in the configuration file.

11.4.8.4 Service Flow Error Parameter Set

This field defines the parameters associated with service flow errors.

A Service Flow Error Parameter Set is defined by the following individual parameters: Error Code, Errored Parameter, and Error Message.

The Service Flow Error Parameter Set is returned in DSA-RSP and DSC-RSP messages to indicate the recipient’s response to a service flow establishment request in a DSA-REQ or DSC-REQ message. The Service Flow Error Parameter Set is returned in DSA-ACK and DSC-ACK messages to indicate the recipient’s response to the expansion of a Service Class Name in a corresponding DSA-RSP or DSC-RSP.

On failure, the sender shall include one Service Flow Error Parameter Set for each failed service flow requested in the DSA-REQ or DSC-REQ message. On failure, the sender shall include one Service Flow Error Parameter Set for each failed Service Class Name expansion in the DSA-RSP or DSC-RSP message. Service Flow Error Parameter Set for the failed service flow shall include the Error Code and Errored Parameter and may include an Error Message. If some Service Flow Parameter Sets are rejected but other Service Flow Parameter Sets are accepted, then Service Flow Error Parameters Sets shall be included for only the rejected service flows.

On success of the entire transaction, the RSP or ACK message shall not include a Service Flow Error Parameter Set.

Multiple Service Flow Error Parameter Sets may appear in a DSA-RSP, DSC-RSP, DSA-ACK, or DSC-ACK message, since multiple service flow parameters may be in error. A message with even a single Service Flow Error Parameter Set shall not contain any QoS Parameters.

A Service Flow Error Parameter Set shall not appear in any DSA-REQ or DSC-REQ messages.

NOTE—The entire Service Flow Error Parameter Set encoding shall have a total length of less than 256 octets.
