View message is set as the first priority value, for safeguarding that the protocol massages of access phase are set below first priority value
Priority value etc..
When NAS receives multiple messages, can be responded according to the sequence of priority entrained in multiple messages.Specifically
Ground, when node server receives the second message and third message, it may be determined that the priority value and third that the second message carries
The size relation between priority value that message carries, the priority value entrained by second message are greater than the third message institute
When the priority value of carrying, after responding second message, which is responded.Entrained by the third message
When priority value is greater than priority entrained by first message, after responding the third message, which is rung
It answers.
204, the NAS sends the sound for being directed to the first ANCP message with the corresponding priority of the first priority value to the AN
Answer message.
For example, then NAS carries clothes in the capability set of the SYNACK message of response when the first ANCP message is SYN message
Business device is the priority that the AN is provided.
It further, will be preferential entrained by message when node server receives any message for carrying priority
Grade preserves, and the subsequent protocol massages for being sent to this access node all use this priority.
The server precedence of the node server can be according to different access node divisions, alternatively, according to access
The portfolio of node divides, and can also divide in real time certainly, such as according to the network condition of current access node, the present invention

First grade is sent to NAS, enables NAS during subsequent transmission protocol massages, and the priority according to required by AN carries out
It sends, and required priority is sent to AN by response message by NAS, enables AN in subsequent transmission protocol massages
In the process, the priority according to required by NAS is sent, so that the priority of protocol massages is able to maintain greater than service message
Priority, uplink and downlink orderly carry out, avoid as protocol massages transmit failure and caused by various connectivity problems.
Certainly, above-mentioned steps 203-205 is handed over according to respective priority between access node and node server
It is illustrated for mutually, and in fact, the access node quantity hung under node server is relatively more, type is also relatively more, each
Network condition is again different, so priority can not be unified to be arranged, therefore, can negotiate two by node server and access node
Message interaction priority between person, to adapt to unused network condition.It that is to say, the NAS and the AN determine the through consultation
Two priority values generate the response message according to second priority value and the first ANCP message, and with first priority
It is worth corresponding priority and sends the response message for being directed to the first ANCP message to the AN.The NAS can according to the AN, this first
At least one of in the priority that the type of message and NAS of ANCP can provide, negotiate to determine the second priority value with AN.
