Problems solved by technology

And because the previous RDSC has not ended (in the DSC-ACK Pending state), there is a situation where two DSC transactions coexist
[0006] In addition, since there are many parameters (TLV) of the service flow, which occupy a large air interface bandwidth, if a certain parameter value does not change, the parameter will not be carried in the DSC-REQ message

Embodiment Construction

[0026] In order to solve one or more problems existing in the prior art, the present invention proposes the following solutions: when the LDSC is in the DSC-RSP Pending or Retries Exhausted state, if the DSC-RSP is received, only the DSC-ACK is sent to the remote end , and transition to the Holding state (such as figure 1 and figure 2 ). In the Holding state, if T10 is overtime, the LDSC sends a DSC Succeeded / DSC Failed message to the SF state machine according to the confirmation value (Confirm Code, CC for short) in the saved DSC-ACK message, and ends itself (such as image 3 ). The SF state machine transitions to the Nominal state upon receiving the message. Therefore, even if the local upper layer initiates the modification immediately, the coexistence of two DSC transactions will not occur, and the loss and retransmission of the message can also be handled.

[0027] Similarly, if RDSC ends itself after receiving SF Changed, then the Holding state is useless. Therefo...

Abstract

The invention discloses a traffic stream modifying process which comprises the following steps: S302, a local traffic stream modifying state machine is generated when modified information is received by a traffic stream state machine, the traffic stream modified message is sent to the local traffic stream modifying state machine, and transition is carried out on the traffic stream modifying statemachine to the local modifying state; S304, traffic stream modifying request information is sent to a remote traffic stream modifying state machine by the local traffic stream modifying state machine, and transition is carried out on the traffic stream modifying state machine to the state of response waiting of the traffic stream modifying; and S306, transition is carried out on the local trafficstream modifying state machine to the state of maintaining on the occasion of receiving the response information of the traffic stream modifying from the remote traffic stream modifying state machine, a second timer with specific time is started, the local business traffic stream modifying state machine sends a successful message or a failed message of the traffic stream modifying to the traffic stream modifying state machine after the second timer is overtime and ends itself. The invention has the advantages that efficiency of empty links can be improved, the serving quality can be ensured and the empty bandwidth is saved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a business flow modification process. Background technique [0002] In the WiMAX system, a base station (Base Station, BS for short) and a mobile station (Subscriber Station, SS for short) initiate modification of a service flow through a service flow modification request (DSC-REQ) message. A successful service flow modification (DSC) includes modification of service flow parameters, admitted (Admitted) and (or) activated (Active) quality of service (Quality of Service, QoS for short) parameter set (set). If the DSC-REQ contains only the Admitted QoS Set, then the Active QoS Set of the service flow is set to NULL, and the service flow is in an inactive state. If neither parameter set is included in the DSC-REQ (that is, the QoS Parameter Set type is set to 000), then the Admitted and Active QoS Set of the service flow are both set to NULL, and the service flow i...
