Embodiment
Basic thought of the present invention is: the calling subscriber when MSC/VLR makes a call; MSC/VLR sends routing inquiry message to MNP-SRF/NPDB; With information such as the IMSI that obtains the called subscriber, RN,, analyze called subscriber's home type then based on information such as called number, IMSI, RN; Combine preset calling subscriber's call blocking condition again, whether decision is called out and is allowed to carry out.
Below in conjunction with accompanying drawing the enforcement of technical scheme is done further to describe in detail.
The MNP business realization mainly contains dual mode: SRF (signaling relay function) mode and IN (intelligent network) mode.The SRF mode mainly adopts MAP (MAP) the implementing signalling MNP that is correlated with; The IN mode mainly adopts the intelligent network message mode to realize MNP; Because the IN mode can't realize the correlation function of the supplementary service of mobile communications network; So what all adopt when introducing number portability service in the general mobile communications network is the SRF mode, the present invention also only introduces based on the SRF mode.
Fig. 1 is the implementation method flow chart of latching service of the present invention, and as shown in Figure 1, the implementation method of latching service of the present invention mainly may further comprise the steps:
Step 101:MSC/VLR receives calling subscriber's call request.
Here, called number is carried in said call request at least.
Among the present invention, when the called subscriber was the mobile subscriber, called number referred to called subscriber's MSISDN.
Step 102:MSC/VLR judges whether to confirm according to called number said called subscriber's home type, if, execution in step 109; Otherwise, execution in step 103.
Here,, can directly distinguish its home type, can't obscure, so, directly judge called subscriber's home type according to called number owing to the enforcement mobile number carrying service causes if called number has obvious characteristic.For example, a lot of national fixed telephone numbers and Mobile Directory Number, two kinds of code schemes are different fully, directly just can distinguish landline telephone or mobile phone from called number.In this case, when the calling subscriber initiated a calling to landline telephone, MSC/VLR can directly analyze called number, combined calling subscriber's call blocking condition (among the ODB, referring to the ODB situation of contract) then, and whether the decision calling can continue.
Step 103:MSC/VLR sends routing inquiry message to MNP-SRF/NPDB.
Here, generally deposit all users' home network information among the MNP-SRF/NPDB.
Routing inquiry message is carried called number at least.
Step 104:MNP-SRF/NPDB judge the called subscriber whether applying mobile number portability service carry out Home Network, if, execution in step 105; Otherwise, execution in step 106.
Here; MNP-SRF/NPDB is specifically according to called number; Search the network No. of the pairing home network of said called number; Can judge the current Home Network that is in of called subscriber according to the network No. of said home network, or applying mobile number portability service carries out Home Network, becomes his network users.
Step 105:MNP-SRF/NPDB returns routing query response message to MSC/VLR, forwards step 108 afterwards to.
Here, MNP-SRF/NPDB generally carries to the routing query response message that MSC/VLR returns: called number, IMSI, and RN etc.
Step 106:MNP-SRF/NPDB sends routing inquiry message to called subscriber's attaching position register (HLR).
Here, MNP-SRF/NPDB carries called number at least to the routing inquiry message that HLR sends.
Step 107:HLR sends routing query response message according to the routing inquiry message from MNP-SRF/NPDB to MSC/VLR.
Here, HLR generally carries to the routing query response message that MSC/VLR sends: called subscriber's mobile subscriber roams sign indicating number (MSRN), IMSI etc., and HLR specifically confirms its MSRN according to called number.
Step 108:MSC/VLR confirms called subscriber's home type according to the routing query response message of receiving, forwards step 110 afterwards to.
MSC/VLR is receiving routing query response message, when confirming called subscriber's home type, multiple processing mode can be arranged, for example:
MSC/VLR can analyze called subscriber's home type according to called subscriber's IMSI, and promptly the IMSI according to the called subscriber judges that it is various situation such as external user, Home Network other places user, local external user;
MSC/VLR also can be according to whether comprising the home type that RN analyzes the called subscriber in the routing query response message of receiving; If comprise RN in the routing query response message; Can judge that then the called subscriber is an external user; If do not comprise RN in the routing query response message, can judge that then the called subscriber is this network users.
In the practical application, system can also be provided with user's RN, makes MSC/VLR be local user or nonlocal user according to the further judges of RN;
MSC/VLR can also promptly if return routing query response message by HLR, can judge that then the called subscriber is this network users according to the office direction analysis called subscriber's of the routing query response message received home type; If return routing query response message, can judge that then the called subscriber is an external user by MNP-SRF/NPDB.
Step 109:MSC/VLR confirms said called subscriber's home type according to called number.
Whether step 110:MSC/VLR combines the preset said calling of call blocking condition judgment to continue, if, execution in step 111; Otherwise execution in step 112.
With ODB is example, if the calling subscriber is signatory BOIC (locking is international breathes out Barring of alloutgoing international calls), and judges that in step 107 called subscriber's IMSI is external IMSI section, and then refusal is this time called out.
During user position update, HLR can insert this user's IMSI, MSISDN, call blocking condition information such as (among the ODB, referring to the ODB CAMEL-Subscription-Information) to MSC/VLR down, and the said preset call blocking condition of this step is promptly stored when user position update.
Step 111: the said calling that continues, flow process finishes.
If MSC/VLR receives the routing query response message from HLR, then according to called subscriber's MSRN replay call, otherwise, according to the called number replay call.
Step 112: refuse said calling, flow process finishes.
