The major number that in various embodiments of the present invention, relates to is meant the number of user in belonging area network, can be as calling number or called number in belonging area network; Minor number is meant the local number that distributes when the user roams into access zone network, can be as calling number or called number in access zone network.
Below in conjunction with Figure of description the embodiment of the invention is described in detail.
As shown in Figure 1, under the situation of one-card multi-number, realizing the method step schematic flow sheet of Voice Mail Service in the embodiment of the invention one, this method may further comprise the steps:
Step 101: one-card multi-number platform is confirmed the voice mail platform number of the execution Voice Mail Service that the roamer customizes in belonging area network.
Step 102: when the roamer carries out the position when upgrading at access zone network; The attaching position register of this roamer's ownership place that one-card multi-number platform will receive (Home Location Register; HLR) Voice mail Number that sends is revised as corresponding virtual number with it; And send to said roamer visit ground mobile services switching centre (Mobile Switching Center, MSC).
The purpose that Voice mail Number is revised as virtual-number is under the situation of conditional forwarding; The MSC on visit ground can't be with call proceeding to real voice mail platform; And one-card multi-number platform is arrived in call proceeding through virtual-number, there is one-card multi-number platform to carry out follow-up operation.Therefore, said virtual-number can be the one-card multi-number platform sign, also can have relation one to one with the one-card multi-number platform sign.
In embodiments of the present invention, one-card multi-number platform can be the platform in the access zone network, also can be third party's network platform, communicates with entity in ownership place and the access zone network.
In this step, for the HLR of roamer's ownership place, one-card multi-number platform can virtually be the MSC on a visit ground; For the MSC that the roamer visits ground, one-card multi-number platform can virtually be the HLR of minor number.
Step 103: after said roamer's minor number begins as the calling procedure of called number, through the routing address of this roamer on visit ground, with call proceeding to the MSC of this roamer on visit ground.
In this step; The MSC that is the calling subscriber in the calling procedure passes through routing address with call proceeding; The method of routing address that calling subscriber's MSC obtains called subscriber's MSC comprises: the route request information (SRI) that calling subscriber's MSC will carry called number (roamer's minor number) sends to one-card multi-number platform; This one-card multi-number platform is revised as major number with the minor number that carries in the route request information, and sends to this roamer's ownership place HLR.One-card multi-number platform is transmitted to the MSC that the called subscriber visits ground after receiving the roaming number request message that ownership place HLR returns, and the routing iinformation that the called subscriber who obtains visits ground MSC is sent to calling subscriber MSC.
Step 104: the calling that the MSC of said roamer on visit ground will carry said virtual-number is routed to one-card multi-number platform, confirm the corresponding Voice mail Number of this virtual-number by one-card multi-number platform after, with call proceeding to the voice mail platform.
Illustrate the implementation of each step below.
As shown in Figure 2, for roamer in the step 102 carries out the signaling process sketch map of position updating process at access zone network, this position updating process may further comprise the steps:
1, the roamer sends location update message (Update_Location) at the international signalling transfer point (ISTP) of the MSC on visit ground to visit ground; (the Signalling Connection control Part of SCCP in this location update message; SCCP) sender address (OriginalAddress of message in; OA) be Visited Location Registor (Visited Location Registor, VLR) sign, recipient address (the Destination Address of message; DA) be E.214; (MobileApplication Protocol is that (International MobileSubscriber Identifier is IMSI) with this MSC sign for international mobile subscriber identifier MAP) to the network interconnection signaling.
2, visit ground ISTP confirms that according to screening mechanism this roamer is the one-card multi-number user, then the location update message that receives is transmitted to one-card multi-number platform.
3, one-card multi-number platform is revised as SCCP:OA parameter in the location update message that receives the sign (RNM ID) of self by the VLR sign; VLR ID among the MAP and MSC ID also are revised as RNMID, and amended location update message is sent to the ISTP that the roamer visits ground.
The purpose that one-card multi-number platform is made amendment to the parameter in the Update_Location message is in order to let the HLR of ownership place think that this one-card multi-number platform is the MSC of roamer on visit ground.
4, the roamer ISTP that visits ground sends to amended location update message the ISTP of roamer's ownership place.
5, the ISTP of roamer's ownership place sends to amended location update message the HLR of roamer's ownership place.
After the 3-5 scheme in step, because the roamer's visiting location information that carries in the location update message that HLR receives is the sign of one-card multi-number self, so this HLR thinks that one-card multi-number platform is the MSC of roamer on visit ground; And the MSC on roamer's visiting location information of in one-card multi-number platform, preserving to be the roamer really visit ground.
6, the HLR of roamer's ownership place returns to the ISTP of roamer's ownership place and inserts user data (ISD) message; The SCCP:OA parameter is a HLR sign (HLR ID) in this ISD message; The parameter of DA is RNM ID; The parameter of MAP is roamer's major number and a conditional forwarding number, and wherein the conditional forwarding number is a Voice mail Number.
7, the ISTP of roamer's ownership place sends to the ISTP that the roamer visits ground with said ISD message.
8, the roamer visit ground ISTP said ISD message is sent to one-card multi-number platform.
9, one-card multi-number platform is revised as RNM ID with SCCP:OA parameter in the ISD message that receives by HLR ID; The parameter of DA is revised as VLR ID by RNM ID; Major number is revised as minor number; Voice mail Number is revised as and Voice mail Number corresponding virtual number, and amended ISD message is sent to the ISTP on visit ground.
The purpose that one-card multi-number platform is made amendment to the parameter in the ISD message is in order to let the MSC on visit ground think that this one-card multi-number platform is the HLR of roamer at ownership place.
10, the ISTP on visit ground sends to the MSC of roamer on visit ground with said amended ISD.
Because what the roamer carried in the ISD message that the MSC on visit ground receives is RNM ID and minor number, so this MSC thinks that one-card multi-number platform is the HLR of roamer at ownership place; And the roamer who preserves in the one-card multi-number platform is that the roamer is really at the HLR of ownership place at the HLR of ownership place.
11, the roamer will return the ISD response message at the MSC on visit ground, accomplish roamer's position updating process.
After the completing place is upgraded; In the calling procedure of minor number with the roamer as called number; When the calling that, no response busy as the roamer or unreachable reason cause can't continue; With the call proceeding of having carried virtual-number to one-card multi-number platform, by one-card multi-number platform with call proceeding to voice mail.
Explain that with position updating process one-card multi-number platform sends to the MSC method of roamer on visit ground with virtual-number in the present embodiment, present embodiment also is not limited to through the method for other (like registration) processes with the virtual-number transmission.
As shown in Figure 3; For in step 103 and the step 104 with call proceeding to the signaling process sketch map of voice mail; Calling subscriber MSC among the figure is meant the MSC of calling subscriber in access zone network that makes a call; Called subscriber MSC is meant the MSC of roamer's (being the called subscriber) on visit ground, and as can be seen from the figure this method may further comprise the steps:
1, the calling subscriber is to the MSC request of making a call of self, and this call request is sent through initial address message (IAM), has carried the minor number (be called number) of roamer on visit ground in this IAM message.
2, calling subscriber's MSC visits ground ISTP to the roamer and sends SRI message, and the SCCP:OA parameter is calling subscriber's MSC ID in this SRI message, and carries minor number simultaneously.
3, visit ground ISTP gives one-card multi-number platform with the SRI forwards that receives.
Minor number is the number that access zone network provides; Calling to minor number is MSC (being calling subscriber's the MSC) initiation by access zone network; Because one-card multi-number platform is virtual for the HLR of minor number and one-card multi-number platform only have the direct signaling link with ISTP when upgrading in the roamer position, so SRI message is forwarded to the one-card multi-number user through ISTP.
4, one-card multi-number platform is revised as one-card multi-number platform sign (RNM ID) with the calling subscriber's in the SCCP:OA parameter in the SRI message MSC sign; And minor number is revised as corresponding with it major number, then amended SRI message is sent to visit ground ISTP.
5, the ISTP amended SRI message that will receive in visit ground sends to ownership place ISTP.
6, ownership place ISTP gives the roamer HLR at ownership place with said amended SRI forwards.
7, the HLR of ownership place will initiate roaming number request message (PRN), and the SCCP:OA parameter in this message is the sign of HLR, show that this message is to be initiated by HLR, and the DA parameter in this message is RNM ID simultaneously, shows this message is sent to one-card multi-number platform.
Because that carry among the SCCP:OA in the SRI message that receives of HLR is RNM ID, so HLR thinks that one-card multi-number platform is calling subscriber's MSC, therefore requires to know the routing iinformation that the roamer belongs to from one-card multi-number platform.
8, the ISTP of ownership place gives the PRN forwards that receives the ISTP on visit ground.
9, the ISTP on visit ground sends to one-card multi-number platform with said PRN message.
10, one-card multi-number platform is RNM ID with the content modification of SCCP:OA parameter in the PRN message; The routing iinformation that the roamer visits ground is inquired about in requirement from VLR; Therefore the RNM ID in the DA parameter is revised as VLR ID, and amended PRN message is sent to the ISTP on visit ground.
Owing in one-card multi-number platform, preserved the MSC of roamer on visit ground, therefore, the HLR of one-card multi-number platform simulation minor number obtains routing iinformation to the roamer in the MSC on visit ground.
11, the ISTP on visit ground sends to the MSC of roamer on visit ground with amended PRN message.
12, the roamer returns PRN_ACK message at the MSC on visit ground to the ISTP on visit ground, has carried mobile communication station roaming number (MSRN) in this message, and the SCCP:OA parameter in this message is VLR ID simultaneously, and the DM parameter is RNM ID.
Because the roamer thinks that at the MSC on visit ground one-card multi-number platform is the HLR of minor number, therefore the routing address (being MSRN) with the roamer returns to one-card multi-number platform.
13, the ISTP on visit ground sends to one-card multi-number platform with PRN_ACK message.
14, one-card multi-number platform is RNM ID with the content modification of SCCP:OA parameter in the PRN response message (PRN_ACK), is HLR ID with the content modification of DM parameter, and amended PRN_ACK message is sent to visit ground ISTP.
It is to return MSRN information in order to simulate the MSC of roamer on visit ground to the HLR of ownership that one-card multi-number platform is made amendment to PRN_ACK message.
15, visit ground ISTP sends to ownership place ISTP with amended PRN_ACK message.
16, ownership place ISTP sends to amended PRN_ACK message the HLR of ownership place.
17, the HLR of ownership place sends to ownership place ISTP with SRI response message (SRI_ACK), has carried MSRN in this message, and SCCP:OA carries is HLR ID, and DA: that carry is RNM ID.
Ownership place HLR thinks that one-card multi-number platform is calling subscriber's MSC, and therefore the routing address with the roamer sends to one-card multi-number platform.
18, ownership place ISTP sends to visit ground ISTP with said SRI_ACK message.
19, visit ground ISTP sends to one-card multi-number platform with said SRI_ACK message.
20, one-card multi-number platform is revised as PNMID with the HLR ID of SCCP:OA parameter among the SRI_ACK, and the RNM ID of DA parameter is revised as MSC ID, and amended SRI_ACK message is sent to the ISTP on visit ground.
Because calling subscriber's MSC thinks that one-card multi-number platform is the HLR of minor number, therefore revise the information of SCCP:OA parameter.
21, the ISTP on visit ground sends to amended SRI_ACK message calling subscriber's MSC.
22, calling subscriber's MSC utilizes the MSRN that receives that the call request of initiating is routed to the MSC of roamer on visit ground, sets up speech channel with it and is connected, and has carried minor number in this call request.
23, because the roamer that a variety of causes causes can't answer this calling; Because the conditional forwarding number that the MSC of roamer on visit ground obtains when upgrading in the position is a virtual-number; Therefore the MSC of roamer on the visit ground call proceeding that will carry virtual-number to international switching center (InternationalSwitching Center, ISC).
24, ISC arrives one-card multi-number platform with said call proceeding.
25, one-card multi-number platform is revised as major number with the minor number in the call request, and virtual-number is revised as corresponding Voice mail Number, and amended call request is routed to ISC once more.
26, ISC arrives the voice mail platform according to the Voice mail Number in the call request with call proceeding, and the voice mail platform inquires the business that the roamer has customized according to major number, and carries out.
