The concrete structure of ASN inside as shown in Figure 2.Wherein, AGW (ASN GateWay, ASN aggregation gateway) and BS (Base Station, base station) connect by internal interface R6 mouth, and wherein, the R6 mouth is made of a series of control and load plane agreement.
Load plane is made of the related data channel protocol between BS and the AGW, and the related protocol that control plane is set up, revised and discharged by the data channel that MS/SS moves generation and enters IDLE and withdraw from IDLE constitutes.AGW realizes based on " NWG_R1_V1.2.2-Stage-3 " agreement.
The miscellaneous service of portable terminal is to carry out setting up on the successful data channel, and Fig. 3 shows the visioning procedure of data channel.As shown in Figure 3, the establishment of data channel may further comprise the steps:
Before creating data channel, MS carries out authentication and mandate, the information of the Business Stream of authorizing, comprise QoS (Quality of Service, service quality), all be kept on the AnchorSFA (Anchor Service Flow Authorization, grappling service flow authorization), comprised the constructive process of the data channel of resource negotiation by Anchor SFA initiation.
Step S301, Anchor SFA sends RR_Req (resource reservation request) message according to the information of the Business Stream of authorizing to ServingSFA (service SFA), and request resource is reserved;
Step S302, Serving SFA are according to RR_Req message, and the construction data passage is created Path_Reg_Req (passage request to create) information and sending and given SFM, the establishment of request msg passage and resource reservation;
Step S303, SFM (Service Flow Management, service flow management) checks whether enough resources are arranged: if there are enough resources to accept request to create, then send out DSA-Request (the passage request to create of eating dishes without rice or wine) message to MS;
Step S304, MS sends DSA-Response (passage of eating dishes without rice or wine is created response) message to SFM, and expression is accepted or refusal;
Step S305, if the result of step S303 and step S304 accepts request, SFM sends Path_Reg_Rsp (passage is created response) message and gives Serving SFA so;
After step S306, Serving SFA receive the Path_Reg_Rsp message of success, send successful RR_Rsp (resource reservation response) message to Anchor SFA;
Step S307, Serving SFA sends Path_Reg_Ack (passage is created and confirmed) message to SFM;
Step S308, Anchor SFA send RR_Ack (resource reservation affirmation) message to Serving SFA after receiving the RR_Rsp message of success.
In above-mentioned flow process, when creating many data channel simultaneously in above-mentioned flow process, there are the following problems:
1. in step S305, when sending Path_Reg_Rsp (passage is created response) message, even the reception of this response is all successes, but when the part failure is arranged in the Serving SFA processing procedure, want Path_Reg_Ack (passage is created and the confirmed) message among the forwarding step S307 to give SFM, because Path_Reg_Ack message has only message header, it does not carry any content yet, therefore can't notify SFM the data channel of failure, cause SFM to think whole successes;
2. in step S308, when sending RR_Ack (resource reservation affirmation) message, if creating, passage all fails or the part failure in this message, all can't notify SFM, this is because at this moment, the Path_Reg_Ack message among the step S307 has sent to SFM.
