Below in conjunction with Fig. 4, implementation procedure and the principle of the method to lifting session interaction performance provided by the invention are further described, to help to understand the present invention.
First be noted that in the method that the present embodiment provides, on ACS, increase a reverse conversation module, that is, ACS comprises reverse conversation module and forward session receiver module; Accordingly, increase a reverse session receiver module on CPE, that is, CPE comprises reverse session receiver module and forward conversation module.
Wherein, oppositely conversation module can send mutual request instruction to CPE by udp protocol, starts for retransmission timer this mutual request instruction, ask alternately instruction for overtime re-transmission simultaneously.Oppositely session receiver module can receive the mutual request instruction of the UDP form of ACS transmission, carries out this mutual request and indicates and notice to forward conversation module.Forward conversation module can be set up forward session to ACS, sends session connection request to ACS, carries out session operation and relevant action.Forward session receiver module can receive the session connection request of the forward conversation module transmission of CPE, carry out session interaction, send and ask alternately successfully mark to reverse conversation module simultaneously, oppositely conversation module receives mutual request and successfully identifies retransmission timer corresponding to rear deletion.
Concrete, oppositely conversation module is for initiating mutual request instruction by udp protocol to CPE, start a retransmission timer for the mutual request instruction of each CPE simultaneously, retransmission timer is used for again sending mutual request instruction to the CPE corresponding with this retransmission timer after overtime, thus the reliability of raising reverse request; The mutual request that simultaneously receives the notice of forward session receiver module successfully identifies, and delete retransmission timer receiving after mutual request successfully identifies, represent that this mutual request instruction has successfully been received by CPE and CPE has carried out corresponding forward session interaction process.
On ACS, the process of session interaction specifically can comprise double teacher, is respectively:
Oppositely the decision phase is carried out in session.When user is on ACS when executable operations request, the operation that this operation requests is user, just enters reverse session and carries out the decision phase.First ACS confirms whether the CPE of opposite end supports the reverse session interaction mode that the present embodiment provides,, whether receive UDP message, decision-making foundation is whether to carry the model value of CPE in the INFORM message noticed of CPE, here why will carry out decision-making is for the existing reverse session interaction mode of compatibility, make the equipment can self adaptation, realize the compatible unified management of the way to manage that existing mode and the present embodiment provide.If support the reverse session interaction mode that the present embodiment provides, carry out the reverse session interaction mode of the present embodiment, otherwise carry out reverse session request according to existing mode.Be understandable that, cpe device also can be supported existing reverse session interaction mode in the reverse session interaction mode of supporting the present embodiment, and cpe device can be managed by the compatibility of two kinds of reverse session requests of ACS.The present embodiment does not limit this.It should be noted that, INFORM message is that CPE sends to ACS after electrifying startup.
Obtain the URL stage of the CPE of reverse request.This URL forces to notice in INFORM message.
The message phase of encapsulation reverse request.To ask alternately instruction to be encapsulated as UDP message, empty HTTP GET request message will be encapsulated in UDP message.
Send the reverse request message stage.The HTTP GET message of the above-mentioned UDP of being encapsulated as message is sent to cpe device by udp protocol.And for this mutual request instruction, start a retransmission timer, the overtime duration of this retransmission timer can be configured by user, tentative 15 seconds of acquiescence, if the overtime rear cpe device of retransmission timer is not also set up forward session to ACS,, do not send session connection request to ACS, ACS resends mutual request instruction for this cpe device, and number of repetition can be configured by user, gives tacit consent to 5 times.Further, in order to optimize retry mechanism, time-out time can calculate by certain algorithm, as 2 of TCP form index scheme.The present embodiment does not limit this.
Based on the reverse session of above-mentioned UDP, each reverse session only needs a mutual message, supreme 8 times in performance, are promoted for original reverse session scheme, adopt overtime retry mechanism simultaneously, greatly improve the reliability of reverse session, solved the depleted problem of existing reverse session tcp port with stylish reverse conversational mode.
On CPE, after having started, CPE just enters reverse session listening state, and be that its reverse well-known serve port (7547) is monitored by the mode of UDP in fact at this state.In the time that reality is used, the port that can monitor by configuration modification as required, the present embodiment does not limit this.
In the time listening to the mutual request instruction of UDP form and arrive, just this mutual request instruction of automatic reception, identifies reverse request, and this mutual request instruction is noticed to forward conversation module, so that forward conversation module sends session connection request to ACS.
