Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
For above-mentioned purpose, the feature and advantage that make the embodiment of the present invention can become apparent more, below in conjunction with the drawings and specific embodiments, the embodiment of the present invention is described in further detail.
With reference to figure 1, in the embodiment of the present invention one, realize that the method that the embodiment of the present invention one provides can comprise the following steps:
Step 101: after MGC succeeded in registration, MGC was added into the access user quantity of this MG in the notification message of access user information as MG.
According to H.248 with the MGCP agreement as can be known, each MG can initiate registration to MGC in actual applications, and each user under this MG does not need to MGC to initiate registration, if MG registers to MGC according to user port, registration message can enlarge several times to tens times, can a large amount of performances that consume MGC.SBC also needs to safeguard each user's login state simultaneously, compares and only safeguards that the MG login state has increased several times and can consume to several decaploidies.Therefore the embodiment of the present invention, consider to have configured whole user data on MGC, and after MGC succeeded in registration, the access user quantity of the MG that MGC just succeeds in registration this was added in the notification message of access user information, then sends to SBC as certain MG.This notification message that carries the access user information of access user quantity need to send to SBC, can adopt the mode according to some cycles transmission heartbeat message to send this notification message, described notification message can be to detect (AUDIT) message or audit endpoint (AUEP) message or conversation initialized protocol (Session Initiation Protocol, SIP) H.248 message, the communication protocol between MGC and SBC can be used or MGCP agreement or Session Initiation Protocol.
The notification message of the access user information that step 102:SBC receiving media gateway controller MGC sends, the notification message of described access user information carries the access user quantity of described MG.
MGC has added number of users information in notification message after, this notification message will be sent to SBC, and carry the access user quantity under the above-mentioned MG that succeeds in registration in this notification message.
Step 103:SBC resolves the notification message of described access user information, to obtain the access user quantity of described MG.
After SBC receives this notification message, resolve this notification message, thereby obtain the access user quantity under described MG.
In embodiments of the present invention, adopt the mode by MGC notice SBC access user quantity, can allow SBC accurately acquire the total number of users information of registration, thereby can provide effective information to carry out plant maintenance and dilatation to support the attendant.
With reference to shown in Figure 2, be the structural representation of the present embodiment whole system when using.Need to prove, the MG in the present embodiment can be one, can be also a plurality of, and when being a plurality of, the access user quantity of a plurality of MG that SBC parses need to be carried out addition as MG, is only access user sum information.
Consider and configured whole user data on MGC, the present embodiment adopts the mode by MGC notice SBC access user quantity, concrete, after MG succeeds in registration to MGC, MGC notifies the number of users under this MG to SBC, further, if the number of users of this MG of the upper configuration of MGC changes, for example have the user deleted, MGC also can notify SBC in the same way again.Therefore, adopt the present embodiment can allow SBC accurately acquire the total number of users information of registration and the number of users also can in time obtain variation from MGC when the access user number change after.Simultaneously, adopt the mode of the embodiment of the present invention to notify SBC access user quantity by MGC, with SBC, each access user is added up to obtain access user quantity mode and compare, also reduced as much as possible the performance consumption to MGC and SBC.
In concrete the application, MGC carries access user quantity in notification message mode has multiple, for (AUDIT) message of the detection in embodiment one or audit endpoint (AUEP) message or sip message, can adopt the mode of expansion new argument to carry number of users information, perhaps carry number of users information by canonical parameter.
The below is in the embodiment of the present invention two, and MGC adopts the mode of expansion new argument to add access user quantity information, with reference to figure 3, realizes that the method that the embodiment of the present invention two provides can comprise the following steps:
Step 301: after MG succeeded in registration, MGC expanded a new argument in the notification message of access user information.
In the present embodiment, take the MGCP agreement as example, MG is registered to MGC by restarting during the course (ReStart In Progress, RSIP) message.After succeeding in registration, can expand a new argument in the MGCP protocol message, by carrying number of users information in this new argument.
Need to prove, inspect between MGC and MG whether interrupt of link because MGC can send AUEP message to MG by SBC, the concrete example of AUEP message is as follows:
Can carry number of users information by the mode of a new argument of expansion in AUEP message in the present embodiment.
Step 302: the new argument of the described expansion of employing is carried the access user quantity under described MG.
Therefore, in the present embodiment, suppose that the new argument of expansion is A, expanding new argument AUEP message afterwards specifically can be as follows:
AUEP?486396263?aaln/1@iadsx?1.com?MGCP?1.0
F：X
A：4293。
Wherein, A is the new argument of expansion, and access user quantity is 4293.Certainly, this extended mode also need to all be arranged at MGC and SBC side.Those skilled in the art also can know, the new argument of above-mentioned expansion is only an object lesson, and this content should not be construed as limitation of the invention.
More than by the explanation of audit endpoint (AUEP) message examples, detect (AUDIT) classes of messages seemingly, no longer describe in detail.
Step 303:SBC receives the notification message of the access user information of MGC transmission, and the new argument in described notification message carries the access user quantity of MG.
Need to prove, the MGC in the present embodiment also can issue AUEP message as the heartbeat message between MGC and MG according to some cycles.
Step 304:SBC resolves the notification message of described access user information, to obtain the access user quantity of described MG.
When SBC receives the AUEP message that MGC sends, just according to decode number of users information in this message of the mode of arranging, thereby obtain the quantity of access user accurately of MG.
Step 305: described SBC deletes the new argument of described expansion from described notification message, and the notification message that will delete after new argument is forwarded to MG.
Need to prove, because the present embodiment is the number of users information of carrying in the new argument of expansion, and MG may not process non-standard extended message, therefore SBC is after obtaining access user quantity, need the new argument of this expansion of deletion, then the notification message that will delete after new argument is forwarded to MG.
When the access user quantity of the MG that configures in described MGC changed, described MGC also can be added into the access user quantity after changing in the notification message of access user information.
In the present embodiment, adopt the new argument of expansion to carry number of users information, can guarantee that SBC can obtain access user sum accurately, then after SBC will delete new argument again, notification message is issued MG, what guaranteed further that MG receives is standard message, simultaneously for the present embodiment, although expanded new argument, SBC needs the new argument of further this expansion of deletion to be forwarded to MG again, but can adopt heartbeat interaction message between original MGC and MG, therefore, also can not affect the performance of MG.
With reference to figure 4, what the embodiment of the present invention three was different from embodiment two is that in MGC employing canonical parameter, mode is added access user quantity information, realizes that the method that the embodiment of the present invention three provides can comprise the following steps:
Step 401: after the MG registration, MGC adds the access user quantity under described MG in the canonical parameter of notification message.
Need to prove, when agreement not simultaneously, the specific implementation of this step can be different.For example, suppose for be the MG of MGCP agreement, should add number of users information in the canonical parameter of MGCP protocol message, for example, can adopt AUEP message to carry access user quantity, this step is namely to add number of users information in AUEP message so, for example:
AUEP?486396263?aaln/1@iadsx1.com?MGCP?1.0
This kind mode is equivalent in the affairs ID of notification message according to a predetermined rule configuration access user quantity information, and this rule need to be scheduled at MGC and SBC side.
again take agreement H.248 as example, MG is registered to MGC by service change (ServiceChange) message, after succeeding in registration, because MGC can send based on the AuditValue order of the Audit descriptor that comprises a sky of " ROOT " to MG by SBC and inspect between MGC and MG whether interrupt of link, therefore can add user profile in this Audit message, for example add " T=378802345 " and represent the number of users that accesses under this MG, described 378802345 is the numerals that generate according to certain coding rule, wherein comprised number of users information, such as represent number of users information with " T=378802345 " last four, represent that namely access user quantity is 2345.Certainly be not limited to this, also can generate the numeral that comprises number of users information by former position or middle several or other coding rules.Perhaps also can directly adopt this mode of T=2345 to represent that access user quantity is 2345.This Audit message of having added number of users information can be as follows:
！/1[160.26.24.1]：2944T＝378802345{C＝-{AV＝ROOT{AT{}}}}
Certainly, those skilled in the art can know that the Audit message of example only is an example in reality, and the content of in fact adding in the Audit message that do not coexist of User quantity is different.Because be the number of users information of adding in the canonical parameter of protocol message H.248, be equivalent to appoint simultaneously at SBC and MGC two sides the concrete meaning that adds content when adopting aforesaid way.
Step 402:MGC sends the notification message of access user information to SBC, the notification message of described access user information carries the access user quantity of media gateway MG.
Step 403:SBC resolves the notification message of described access user information, to obtain the access user quantity of described MG.
Step 404: described SBC directly is forwarded to MG with the notification message of described access user information.
What the present embodiment was different from embodiment two is, because there is no new argument, SBC just can be directly be forwarded to MG with the notification message of access user information.
Step 405: when the access user quantity of the MG that configures in described MGC changed, the access user quantity after described MGC will change was added in the notification message of access user information.
And in the present embodiment, when variation has occured for the access user quantity of MG, access user quantity after MGC just needs immediately will adapt is added in the notification message of access user information, thereby informs the current sum of access user accurately of SBC information by issuing this notification message.Mentioned herein and notification message transmission and previous embodiment in the process introduced consistent, just repeat no more at this.
The present embodiment is guaranteeing that SBC obtains on the basis of access user quantity accurately, directly use H248 and the original heartbeat message of MGCP agreement when concrete the application, therefore minimum to the performance consumption of MGC and SBC, can also be on the basis that does not affect MGC and SBC performance, the access user quantity that changes has occured in real-time notice SBC.
In actual applications, access user information in the embodiment of the present invention can also pass through conversation initialized protocol (Session Initiation Protocol, SIP) message or other privately owned Extended Protocols carry access user quantity, the content class that its implementation is all introduced with previous embodiment seemingly, those skilled in the art can obtain according to the record of previous embodiment the implementation procedure of other privately owned Extended Protocols.
With reference to figure 5, in the embodiment of the present invention four, MGC adopts sip message to carry access user quantity, realizes that the method that the present embodiment provides can comprise the following steps:
Step 501: after MGC succeeded in registration, MGC was added into the access user quantity of this MG in the sip message of access user information as MG.
In the present embodiment, described notification message specifically adopts sip message to realize, MGC has added access user quantity in sip message, so this sip message carries the access user quantity of MG.Need to prove, sip message also can adopt other privately owned Extended Protocols to replace.
The sip message of the access user information that step 502:SBC receiving media gateway controller MGC sends carries the access user quantity of described MG in described sip message.
Step 503:SBC resolves the sip message of described access user information, to obtain the access user quantity of described MG.
Step 504: when the access user quantity of the MG that configures in described MGC changed, the access user quantity after described MGC will change was added in the sip message of access user information.
The present embodiment can realize equally that by sip message or other privately owned Extended Protocols SBC obtains the purpose of access user quantity accurately.
Need to prove, for aforesaid each embodiment of the method, for simple description, therefore it all is expressed as a series of combination of actions, but those skilled in the art should know, the present invention is not subjected to the restriction of described sequence of movement, because according to the present invention, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art also should know, the embodiment described in specification all belongs to preferred embodiment, and related action and module might not be that the present invention is necessary.
