Below in conjunction with Figure of description the specific embodiment of the present invention is described.
Be the structural representation of the ORP that designs of the present invention as shown in Figure 2, as we can see from the figure, roamer's routing optimality equipment of the present invention is connected by signaling with HLR with the MSC equipment of caller, mainly comprises:
Signaling receiving and transmission processing module: be responsible for receiving and sending the standard interface signaling that can transmit user profile between the mobile communications network network element, such as the Signaling System 7(SS-7) in the GSM network, MAP, CAP etc., carry out information interaction with the routing optimality analysis module, this mutual content mainly comprises: the information that receives sends to the routing optimality analysis module and handles, the information that the routing optimality analysis module is sent here sends to the network element of appointment, and wherein external signalling being sent all is to finish by the signaling receiving and transmission processing module.
Routing optimality analysis module: be mainly used in analyzing and processing route requests signaling, according to CSI called subscriber identification wherein, generally be called subscriber's mobile number MSISDN, query ID section and HLR corresponding data table judge whether this user ID is mobile user identification, whether can obtain the optimization route, analyze the purpose network element of this routing iinformation request; And, send the route requests signaling of appropriate format to this purpose network element according to the information in the above-mentioned route requests signaling; If table look-up the failure then refuse this routing optimality request.After receiving the routing iinformation that the purpose network element returns, send to the network element of this information of request.
Number section and HLR corresponding data table: the data of storage section and homing position storage network element corresponding relation, judge whether a number section is mobile number, whether corresponding homing position storage network element is arranged, permission is optimized route etc. and is finished and optimize the needed data of route, can by man-machine interface maintenance be set by operator.
The notion of its medium size section is exactly an identical set of numbers of preceding x position, is exactly the processing mode that decides this set of numbers by x position before judging in communication.
Number section and HLR corresponding data maintenance interface: operator is used for being provided with the man-machine interface of maintenance section and HLR corresponding relation data.
As shown in Figure 3, it is the present invention obtains to optimize route by ORP networking schematic diagram, each MSC is connected by signaling network with ORP, ORP is connected by signaling network with HLR, the calling and called user is in same visit ground mobile network, wherein VMSCA is the VMSC that access service is provided for calling subscriber A, and GMSCA is the GMSC (if caller is its network users then can needs GMSCA to be responsible for asking route) that service is provided for calling subscriber A.VMSCB is the VMSC that access service is provided for called subscriber B, and it is that expression is connected by direct speech channel with the MSC of caller in this legend.HLRB is the attaching position register of called subscriber B.
As can be seen from the figure, in the application of reality, ORP does not have speech channel with the roaming place telecommunications network and is connected, have only signaling to connect, MSC or GMSC with the roaming earth mat links to each other by signaling, with the ownership place mobile network also is not have speech channel to be connected, and links to each other with the HLR or the MSC of ownership place mobile network by signaling.
In network, ORP accepts the caller of mobile communication and moves the optimization route requests that innings equipment comprises VMSC/MSC SERVER etc., obtains called routing iinformation to home location register HLR, such as: MSRN returns to caller and moves office.
Move office and the interface of ORP for caller, owing to be to be used for transmitting optimization route requests and response signaling thereof, finishing this function according to the actual conditions employing appropriate signaling of the employing network equipment and networking gets final product, for example can be the CAP signaling--require caller to move innings side apparatus and support the SSF function, ORP equipment is supported the SCF function; Also can be that MAP signaling-caller office of moving judges that directly transmission SRI is to ORP when needing the optimization route, ORP be responsible for and HLR is mutual accordingly, obtains routing iinformation; Can also transmit by USSD--require caller is moved definite USSD application service between office and the ORP relation etc.
Wherein, the interface of ORP and HLR, identical with MSC in the existing standard and HLR interface, signaling and wherein cell all need not change.
When stating roamer's routing optimality equipment in the use, may further comprise the steps:
Step a: the MSC of caller initiates to optimize the route requests signaling to ORP;
Caller is moved innings equipment according to user indication or when enabling automatic judgment mechanism and judging that this is called out needs and optimizes route, initiates to optimize the route requests signaling to ORP.
In fact in step a, also comprise an ORP checking route requests, if ORP judges that this calling does not need maybe can not provide the optimization route, then instruct MS C gives user's playback prompting back call release,
The mode of submitting to of this route requests has multiple, can earlier a special service number be set at local side, when using, dials the step of this special service number+called number to the route optimisation process business of the MSC of caller triggering by the user.
When dialing " special service number prefix+called number ",, also need before called number, add international dialing prefix and called home country number if the called subscriber is the called number in the international roaming subscriber dialing the user.
This special service number prefix is the professional special service number prefix of this country's appointment " the international roaming mobile subscriber optimizes route ", and the mobile switching center that serves in the network sends route requests according to this prefix to ORP.
The MSC of end office (EO) also can the user send special indication in addition, the called number feature by judging existing dialing (for example: the international dialing prefix, or international dialing prefix+national code etc.), initiate to optimize route requests automatically.Judge whether to optimize route by ORP, can not optimize route and then send international gateway to handle according to existing mode.Can optimize then and handle according to optimizing route.
Need preferred route if the special service number prefix is judged by end office (EO), then it can send route requests to ORP by following several modes:
(1) ask route by MAP signaling SRI to ORP, ORP judges called number and finds corresponding HLR that obtain routing iinformation, the ORP under this mode can transform or increase corresponding ORP function and finish based on HLR equipment.
(2) if MSC includes SSF (service switch function Service Switching Function) functional module, ORP has SCF (service control function service control function) functional module, also can be triggered to ORP by the CAMEL signaling, ORP judges called number and finds corresponding HLR, obtain routing iinformation, the ORP under this mode can transform or SCP increases signaling gateway function and finishes based on SCP.
(3) if MSC and ORP comprise the application module and the interaction protocol of USSD or short message, can also ask route to ORP by the USSD signaling method, ORP judges called number and finds corresponding HLR, obtains routing iinformation.Caller under this mode is moved the USSD application function that will develop correspondence between office and the ORP and is finished.
(4) ask route by the mode of short message to ORP, ORP judges called number and finds corresponding HLR, obtains routing iinformation.
If return be transferred number could:
(1) judges by ORP directly and ask route once more that ORP returns to end office (EO) to the final route number of finally obtaining, return the routing number while and also will return transferred number because preceding commentaries on classics has taken place.(MSC of caller need increase the processing to this message)
(2) can subscriber call, commentaries on classics can not be used the optimization route before the called generation, please directly dials, and can pass through voice or SMS this moment, and USSD sends to the calling subscriber to transferred number.(MSC of caller need not special processing)
(3) transferred number is returned to caller and move office, and indicate whether to initiate optimization request once more, if ORP judges that transferred number is a mobile number, the caller office of moving initiates the routing optimality request once more.(MSC of caller needs to optimize once more preceding commentaries on classics the processing of sign).
The preceding commentaries on classics is the supplementary service of a standard in the mobile communication, and the user can transfer to the calling of incoming call on other calling terminals by registering this business, such as landline telephone or other mobile phones or Special Service Console.
The preceding commentaries on classics that general mobile subscriber can select has:
Call Forwarding Unconditional, (all callings of going into all before forward the transferred number that the user sets to)
Divert when busy, (when the user is busy, going into Call Forwarding) to the transferred number of setting
Call Forwarding No Reply, (do not have off-hook to reply when the user surpasses the time of setting, go into Call Forwarding)
Call Forwarding on mobile subscriber Not Reachable, (when user shutdown, or commentaries on classics before during out of reach)
If the user was provided with Call Forwarding Unconditional or user shutdown and is provided with Call Forwarding on mobile subscriber Not Reachable when roaming number was got by system, then HLR can return transferred number, rather than roaming number.
When HLR gets roaming number, user's shutdown this moment if this called subscriber is provided with Call Forwarding on mobile subscriber Not Reachable, or the user is provided with Call Forwarding Unconditional, then HLR can not return roaming number, can directly return the transferred number that the user is provided with, this number can be fixing, moves and waits arbitrary numbers
Step b:ORP selects the attaching position register of called correspondence according to called number, to its request route information;
By the relevant information of ORP according to called number, select its corresponding HLR, and request route information.
Step c: attaching position register returns routing iinformation to ORP;
HLR is the route of ORP request, returns to caller and moves and serve the MSC of switching center.
Steps d: ORP sends to routing iinformation the MSC of caller;
After ORP obtains routing iinformation that attaching position register HLR returns, send it to caller and move office, this information generally is: MSRN (MSRN:mobile subscriber roaming number roaming number) or FN (FN:Forwarded-to number transferred number.), or failure information;
If what return is transferred number, this transferred number is the called mobile number that belongs to state, and then ORP can indicate the MSC of caller to ask ORP to optimize route once more;
If what return is failure information, then according to the existing procedure terminated call, can send announcement information to the calling subscriber, direct terminated call then, or with original routing mode continuation replay call.
By ORP corresponding failure cause is returned to MSC if HLR returns failure information, MSC does subsequent treatment according to the prior art standard.
Step e: the routing iinformation routing that the MSC of caller returns according to ORP obtains to optimize route.
The routing iinformation routing that caller MSC returns according to ORP can send and be prompted to the called subscriber simultaneously, shows that this calling is to optimize routing call, and this prompting can be that caller MSC sends, and also can be that ORP sends.For example: by changing the calling number of sending by caller MSC to adopting the calling of optimizing route selection in this example, increase special clothes prefix in its front, show that to called this calling is the calling of optimizing route.Can certainly be to the called notice that sends SMS message.
Success can send prompting to the called subscriber in continuing after obtaining to optimize routing iinformation, shows that this calling is the calling of optimizing route, needn't pay circuitous international long-distance expense.The mode of prompting can be to change caller ID display, sends voice suggestion, sends message notifying etc.
The signaling process figure of said process as shown in Figure 4.Wherein:
GMSCA serves switching center's (being responsible for the route that the party A-subscriber asks called B) for calling subscriber A provides the critical point of service to move
VMSCB serves switching center for called subscriber B provides the visit of access service to move
The attaching position register of HLRB called subscriber B
ORP routing optimality equipment
PLMN Public Land Mobile Network-Public Land Mobile Nerwork
The visit ground PLMN at the called place of VPLMN Visit PLMN-
The PLMN of HPLMN Home PLMN-dialed field
Fig. 5 is the calling-calling and called A that obtains to optimize route by ORP, and B is with the situation of office, and as can be seen from the figure, calling both sides is directly set up conversation at local exchange, does not have alternate route.
Fig. 6 is the calling-calling and called A that obtains to optimize route by ORP, the situation of the different offices of B, wherein:
VMSCA provides the Visited Mobile Switching Center of access service for calling subscriber A
GMSCA provides the gateway MSC of service for caller A
VMSCB provides the Visited Mobile Switching Center of service for called B
VLRB provides the VLR Visitor Location Register of service for called B
The attaching position register of the called B of HLRB
As we can see from the figure, if the MSC that finally continues of calling and called has direct-connected speech channel then can set up the most direct route, otherwise can choose according to the network configuration of locality.
Below be the situation that telex network obtains routing iinformation for example, therefrom can see that this method is simple, it is comparatively convenient to implement management.Be in operation, optimize the existing network that the equipment ORP of route agent is relatively independent of operator, concentrate the optimization route requests of being responsible for handling network element in the network, finish the optimization route acquisition more independently, only move innings equipment and HLR carries out Signalling exchange with caller.Can set up one or morely according to actual conditions, concentrate the optimization route service finish the whole network.Existing network device just configuration data is issued ORP to route requests and is got final product.Little to existing mobile network equipment influence, be convenient to networking and operation management.Simultaneously, this programme does not influence the rule of the original Route Selection of mobile network, only the calling of needs optimization route is handled, and the user can determine whether the calling of its initiation needs the routing optimality service.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
