Abstract
The present invention discloses a method for triggering call charge, which comprises the steps that an MSCe sends a request message for establishing the calling IP load bearing to an MGW after receiving a calling establishing request message, and the charging center is triggered to call for charging after a called answer is detected and the call IP load bearing is established. Charging errors caused by that the charging center is triggered to call for charging because the calling IP load bearing is not successfully established are avoided, and thus, users' loss is avoided. Specifically, for the situation that the calling side is IP load bearing, namely that the calling side and the called side are both the IP load bearing or only the calling side is the IP load bearing, the MSCe can be successively called after the IP load bearing is successfully established at the calling side, and the MSCe can simultaneously carry out successive called operation and establish the IP load bearing at the calling side.
Description
Technical field
The present invention relates to the call charging field in the mobile communication, be specifically related to a kind of method that triggers call charging based on the soft-exchange construction of IP carrying down.
Background technology
Soft switch is by the next technical system that the carrier class business is provided to the user of mode that control separates with carrying is separated, called out to business and calling control.Basic carrying media in the soft switch has two kinds: based on the hardwired link passage and the IP-based real-time transport protocol (rtp) Media Stream of time division multiplexing (TDM).
Fig. 1 is that as shown in Figure 1, the function of each several part is as follows based on the soft-exchange construction figure of IP carrying:
Mobile soft switch center (MSCe): mainly realize session, Call Session Control Function,, realize action control to MGW simultaneously as media gateway (MGW) controller;
MGW: mainly realize bearing function, set up carrying, and report carrying dependent event etc. to MSCe according to the control command of MSCe;
IP base station (IPBSS): refer to that the A interface adopts the BSS of IP carrying, its effect is identical with traditional B SS.
Newly-increased interface A1p between MSCe/MGW and the IPBSS corresponding to traditional A2 interface, is respectively applied for the transmission that realizes signaling and speech data corresponding to traditional A1 interface, A2p.MSCe/MGW also can link to each other with the A2 interface by A1 with non-IP base station controller (BSC);
Interface between MGW and the MGW is the yy interface;
Interface between MSCe and the MSCe is the zz interface;
Interface between MSCe and the MGW is the 39/xx interface.
At present, under soft-exchange construction, trigger the charging center by MSCe according to the called party answer situation and begin call charging based on the IP carrying.
Fig. 2 is the message flow sequential chart that triggers call charging under the calling and called side all is the soft-exchange construction of IP carrying, and as shown in Figure 2, its key step is as follows:
Access (INVITE) message that the preceding switch of step 201:MSCe reception self is sent, this access information carries the address information of the preceding switch that sends this access message.
The preceding switch here specifically refers to MSCe.
Step 202:MSCe by called place IPBSS to called transmission paging request message.
Step 203: called receive paging request message after, return page-response message to MSCe, this page-response message is carried called place IPBSS address information.
After step 204:MSCe receives page-response message, send adding (ADD) message to MGW, this adding message is carried the address information that sends the preceding switch that inserts message.
After step 205:MGW receives and adds message, respectively according to the address information that sends the preceding switch that inserts message, the address information of called place IPBSS, set up calling and called side IP carrying, and return response message to MSCe.
After step 206:MSCe receives response message, return 183 session progress message to sending the preceding switch that inserts message.
Step 207: after the preceding switch of transmission access message is received 183 session progress message, return Temporary Response to MSCe and confirm (PRACK) message.
After step 208:MSCe receives the Temporary Response acknowledge message, return 200 response messages to sending the preceding switch that inserts message.
Step 209:MSCe sends assignment request message to called place IPBSS, and this assignment request message carries MSCe side address information.
Step 210:MSCe receives the assignment that called place IPBSS reports and finishes message.
Step 211: called place IPBSS detects called party answer, sends to MSCe to connect (CONNECT) message, and the triggering charging center began call charging after MSCe received this connection message.
Step 212:MSCe sends at 200 response messages that insert message to sending the preceding switch that inserts message.
Step 213: the preceding switch of transmission access message returns at affirmation (ACK) message that inserts message to MSCe after receiving that 200 responses disappear.
From flow process shown in Figure 2 as can be seen, as long as MSCe detects called party answer, just trigger the charging center and begin call charging, that is: MSCe does not consider whether the IP carrying of calling and called side has set up success.In actual applications, when IP network causes quantity of operation to descend for various reasons, the speed of setting up of IP carrying will be slack-off, but the speed that signaling continues is not subjected to the influence of IP network, still can finish at short notice, therefore when called party answer, the IP of possible calling and called side carrying is not set up successfully as yet, therefore MSCe triggered the charging center and began call charging and can cause carrying out in advance call charging this moment, caused damage to the user.
