Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of acquisition method, system and equipment of IP bearing path quality.
Background technology
Conventional switch has been divided into two part: MGC (Media GatewayController, Media Gateway Controller) and MGW (Media GateWay, media gateway) after adopting soft-exchange construction.MGC in the mobile soft switch scene is MSCe (Mobile Switch Center emulation, mobile soft switch center emulation), and for mobile core network, MSC originally has been divided into MSCe and MGW.As shown in Figure 1.Generally adopt signaling H.248 to finish the associative operation of carrying between MGC and MGW.Support SIP (Session Initiation Protocol, Session initiation Protocol) signaling between MGC, can carry out Signalling exchange and carrying foundation on the net at IP (Internt Protocol, Internet protocol).
H.248 comprise two basic conceptions in the signaling: related (Context) and destination node (Termination).Association shows the annexation between some destination nodes.Null Context is a kind of special association, and it comprises the destination node that all and other destination nodes are not got in touch.Destination node is a logic entity on the MGW, and it is initiated or receiving media flows, control flows.The type of destination node comprises semipermanent destination node and provisional destination node two classes.Semipermanent destination node can the represents physical entity, a TDM (Time DivisionMultiplexing, time division multiplexing) channel for example, and at this moment, as long as there is this channel among the MGW, this destination node just exists.Provisional destination node can be represented provisional information flow, as RTP (Real-time TransportProtocol, RTP) stream, at this moment, has only when MGW uses these information flows, and this destination node just exists.Provisional destination node is created by Add (interpolation) order, deletes with Subtract (deletion) order, just exists after only being created for provisional destination node, just no longer exists with Subtract order deletion back.The semipermanent destination node is then different, when using the Add order when the physics destination node is added in an association, this physics destination node is from null Context, and when using the Subtract order from an association during deletion of physically destination node, this physics destination node will be transferred in the null Context.For the physics destination node on the MGW, MGC can be known its physical state by audit process.For provisional destination node, have only establishment after, could know the physical carrier state by audit process.Provisional destination node is in case delete just no longer existence from association.
Fig. 2 is a process of setting up the interoffice IP bearer path in the prior art at the mobile soft switch scene next one, MGC in the wherein mobile soft switch scene is MSCe (Mobile Switch Center emulation, mobile soft switch center emulation), its concrete steps are as follows:
Step s201, MSCe1 create an IP temporary destination node with ADD (interpolation) order notice MGW1.
Step s202, MGW1 distribute temporary destination node, in ADD Reply (adding response) message the physical IP address information of temporary destination node are returned to MSCe1.
Step s203, MSCe1 send INVITE (invitation) message to MSCe2, the physical address information of band local terminal IP end points in message.
Step s204, MSCe2 create an IP temporary destination node with ADD order notice MGW3, have the physical address information of opposite end IP end points in message;
Step s205, MGW3 distribute temporary destination node, and the physical IP address information temporary destination node in ADD Reply response message returns to MSCe2.
After step s206, MSCe2 obtain the physical address information of local terminal IP end points, this information is passed through 180 message informing MSCe1.
After step s207, MSCe1 obtain the physical address information of opposite end IP end points, notify MGW1 the physical address information of opposite end IP end points by Modify (notice) message.
After step s208, MGW1 receive Modify message, send Modify Reply response message to MSCe1.
Through above process, after the MGW at two ends obtains local terminal IP end-point addresses information, opposite end IP end-point addresses information, thereby set up the interoffice IP bearer path.
Can find out from said process, in calling procedure, pass through Signalling exchange by MSCe, behind peer IP address notice MGW, MGW Random assignment temporary destination node is set up the IP bearer path, and before not setting up the IP bearer path, can't know interoffice IP bearing path quality situation, therefore can not manage as semipermanent physics destination node for the interoffice IP bearer path, can not effectively guarantee the quality of the IP bearer path that interoffice is set up.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail:
In the embodiments of the invention one, a kind of acquisition method of IP bearing path quality may further comprise the steps as shown in Figure 3:
Each MGW proceeds to the IP bearing path quality detection of each MGW under the MGC of opposite end under step s301, the local terminal MGC notice local terminal.
Wherein, when each MGW carries out the detection of IP bearing path quality under the local terminal MGC, need to arrive the IP bearer path information of each MGW under the MGC of opposite end.The method that each MGW gets access to the IP bearer path information of each MGW under the MGC of opposite end under the local terminal MGC can have following two kinds:
(1) notifies by local terminal MGC.
Local terminal MGC obtains the IP beared information of each MGW under the IP beared information of each MGW under the local terminal MGC and the opposite end MGC.This IP beared information comprises: the carrying IP address information of MGW, respectively carry the bandwidth of IP address and disposal ability etc.Local terminal MGC is according to this message that gets access to, obtain the IP bearer path of each MGW under the MGC of opposite end of each MGW under the local terminal MGC, and with each MGW under this IP bearer path information notice local terminal MGC, the method for notice can be carried out in the message of IP bearing path quality detection for being added on each MGW of notice local terminal.
(2) in advance on each MGW of local terminal, be configured to the IP bearer path information of each MGW under the MGC of opposite end.
Step s302, local terminal MGC receive the IP bearing path quality testing result that each MGW sends under the local terminal MGC.
In the embodiments of the invention two, describing embodiments of the present invention in conjunction with a concrete networking scene, is example with mobile soft exchanging network, under the wherein mobile soft switch center emulation MSC e1 two MGW:MGW1, MGW2 is arranged; Two MGW:MGW3, MGW4 are arranged under the MSCe2; The carrying IP address of supposing MGW1 is that the carrying IP address of IP1, MGW2 is that the carrying IP address of IP2, MGW3 is that the carrying IP address of IP3, MGW4 is IP4.
Under this networking scene, the acquisition method of a kind of IP bearing path quality of the present invention for MSCe1 obtains the carrying IP address information of opposite end MGW3 and MGW4 and notifies the MGW1 and the MGW2 of local terminal, specifically may further comprise the steps as shown in Figure 4:
Step s401, MSCe1 obtain the IP beared information of each MGW under the local terminal MSCe, and wherein the carrying IP address of MGW1 is that the carrying IP address of IP1, MGW2 is IP2.
Step s402, MSCe1 obtain the IP beared information of each MGW under the MSCe2 of opposite end, and wherein the carrying IP address of MGW3 is that the carrying IP address of IP3, MGW4 is IP4.
Step s403, MSCe1 obtain the interoffice IP bearer path according to the carrying IP address information of each MGW under the carrying IP address information of each MGW under the local terminal and the opposite end MSCe2.
For the situation in the present embodiment, the interoffice IP bearer path has four: IP1＜-IP3, IP1＜-IP4, IP2＜-IP3, IP2＜-IP4.
Step s404, at each IP bearer path of interoffice, MSCe1 notifies under this MSCe each MGW to carry out the IP bearer path and detects.
MSCe1 carries IP bearer path information in notification message, this IP bearer path information comprises the carrying IP address information of opposite end MGW, is specially herein: MSCe1 notice MGW1 detect the path IP1 of MGW3＜-IP3 and to the path IP1 of MGW4＜-IP4; MSCe1 notice MGW2 detect the path IP2 of MGW3＜-IP3 and to the IP2 of MGW4＜-IP4.
After step s405, MGW obtain IP bearer path information, according to comprising opposite end carrying IP address information, carry out the IP bearing path quality and detect, and testing result is reported MSCe1, MSCe1 upgrades each IP bearer path situation.
MSCe1 can require MGW that IP bearer path situation is only reported once when requiring MGW to report testing result, also can require MGW to carry out periodic report.
When step s406, foundation carrying, MSCe1 selects suitable MGW to set up the call bearer path according to each IP path carrying situation.
When setting up call bearer,, the carrying entity is distributed in proportion if each path carrying quality is good.For example adopt the mode of polling, once select MGW1, once select MGW2; Perhaps adopt pre-configured mode, for example the ratio of pre-configured MGW1: MGW2 is 1: 2 on MSCe1, promptly selects MGW1 one time, selects MGW2 twice, and selection hockets; If the carrying quality problems appear in the path that has, select other measured paths of carrying matter to set up call bearer.
For example, the interoffice of setting up between MSCe1 and MSCe2 of being initiated by MSCe1 carries, and MSCe1 is four bearer paths relatively, if discovery IP1＜-the IP4 quality is better, then selects MGW1 to set up local terminal IP carrying; MSCe1 notifies MSCe2, carries the carrying IP address information of local terminal MGW; After MSCe2 obtains the carrying IP address information of opposite end MGW, discovery have two qualified path: IP1＜-IP3, IP1＜-IP4, MSCe2 select wherein quality preferably IP1＜-IP4, its corresponding local terminal MGW is MGW4, then selects MGW4 to set up the interoffice carrying.
Among the step s401, the IP beared information method that MSCe1 obtains each MGW under the local terminal MSCe has following three kinds:
Method one requires MGW to report the IP beared information for MSCe1 initiates audit, and as shown in Figure 5, concrete steps are as follows:
Step s501, MSCe1 each MGW under local terminal MSCe sends audit request AuditValue message, requires each MGW to report the IP bearing resource of self.
After step s502, MGW receive message, report the IP beared information of oneself by AuditValue Reply: comprise bandwidth, disposal ability of carrying IP address, the IP address of MGW etc.
Thus, MSCe1 can get access to the IP beared information of MGW according to the response message of MGW.
Method two is that MGW initiatively reports the IP beared information, is specially MGW by Notify (notice) message, the IP beared information of MGW notice MSCe1.
Method three disposes the IP beared information on each MGW for directly to carry out data configuration on MSCe1.
Among the step s402, MSCe1 obtains the IP beared information of each MGW under the MSCe2 of opposite end, and method has following three kinds:

After step s601, MSCe2 obtain the IP beared information of each MGW under this MSCe, initiatively send INFO (notice) message and give MSCe1, in message, carry the IP beared information that local terminal is set up the MGW that call bearer uses.
Step s602, MSCe1 send confirmation 200 OK to MSCe2 after receiving INFO.
Method two is that MSCe1 sends message to MSCe2, requires MSCe2 to return it and sets up the IP beared information that call bearer is used, and concrete steps are as follows:
MSCe1 sends message to MSCe2, requires MSCe2 to return it and sets up the IP beared information that call bearer is used; Can also carry local terminal carrying IP address information in this message.
After MSCe2 receives message, send 200 OK message, carry its IP beared information in the message to MSCe1.
Method three is at the enterprising line data configuration of MSCe1, the IP beared information of each MGW under the configuration opposite end MSCe2.
Among the step s405, the method that the IP bearing path quality is checked can or be used new mechanism with existing mechanism.Use existing mechanism, when inter-entity does not have call bearer to set up, whether can detect the IP path of inter-entity with the PING mode normal, after setting up call bearer in this path, adopt RTCP (RealtimeTransport Control Protocol, RTCP Real-time Transport Control Protocol) mode to detect the IP bearing path quality.
Use new mechanism to carry out method that the IP bearing path quality detects as shown in Figure 7, concrete steps are as follows:
Step s701, entity 1 initiate to detect automatically, send detect-message to entity 2 at a certain time interval, have source sign (sign of entity 1), purpose sign (sign of entity 2) and specific tag value in the message, record current time when entity 1 sends message.
Step s702, entity 2 are received detect-message, if purpose sign is identical with the sign of itself, entity 2 sends to entity 1 and detects response message, its tag identify with the message of receiving in consistent.
After step s703, entity 1 are received and are detected response message, the current time of message received in record, find moment of corresponding transmission message according to the tag value in the message, deduct the moment that sends message with the moment of receiving message and obtain message transmission and processing time at interval.
Step s704, entity 1 be according to the response condition of each message, calculates when pre-treatment average time, number of dropped packets.
Step s705, entity 1 judge the transmission quality of 2 of entity 1 and entities and the disposal ability situation of change of entity 2 according to the variation of processing time and number of dropped packets.
Similarly, also can take following method:
Afterwards, entity 1 statistics sends the number of times of message and the detection response message number of times that receives, and in conjunction with handling time interval variation, obtains IP bearing path quality situation.
In the above-mentioned steps, entity 1 is MGW1 or MGW2, and entity 2 is MGW3 or MGW4.
Among the step s405, MGW reports the method for IP bearing path quality testing result can be for once reporting or periodic report.
Wherein, the concrete steps that once report IP bearing path quality testing result are for as shown in Figure 8:
Step s801, MSCe send AuditValue audit message to MGW, require MGW to report the bearing path quality testing result.
Step s802, local terminal MGW and opposite end MGW obtain IP bearing path quality information alternately.
Step s803, MGW send AuditValue Reply response message to MSCe, report IP bearing path quality testing result simultaneously.
Wherein, MGW periodic report IP bearing path quality testing result as shown in Figure 9, concrete steps are:
Step s901, local terminal MSCe send AuditValue audit message to MGW, require MGW to report IP bearing path quality testing result.
Step s902, local terminal MGW and opposite end MGW obtain IP bearing path quality information alternately.
Step s903, MGW send AuditValue Reply response message to MSCe, report IP bearing path quality testing result simultaneously.
Step s904, through one section prior all after date of regulation, local terminal MGW and opposite end MGW obtain IP bearing path quality information again alternately.
Step s905, MGW send the Notify notification message to MSCe, and send the IP bearing path quality testing result after upgrading simultaneously.
After step s906, MSCe receive Notify message, send Notify Reply response message.
Among above-mentioned steps s904～step s906, MGW also can carry out the IP bearing path quality always and detect, every a cycle of stipulating in advance, when arrival need report the moment of IP bearing path quality, just to Notify information reporting IP bearing path quality testing result of MSCe transmission.
