Technical field
The present invention relates to the mobile intelligent net technical field, refer to especially realize that method and system and a kind of service control point, a kind of short-distance wireless IAD and a kind of short-distance wireless that calling line number shows access terminal.
Background technology
Mobile intelligent net is the functional unit that increases some intelligent networks on existing mobile network, as: Service Control Point, Service Switching Point etc., service control function is separated from traditional function of exchange, make network that new business can be provided flexibly and easily, to adapt to user's demand.It is existing mobile network and the combining of intelligent network.
(CAMEL, Customized Applicationsfor Mobile Network Logic) used in the customization of mobile network's enhanced logic is a kind of IN service based on mobile network, has adopted the service control function of intelligent network.The specific implementation of CAMEL is divided into two steps, at first in the GSM network, introduce the agreement of intelligent network, define each part in the GSM network according to the network configuration of intelligent network and signalling point pattern, (HLR) can be used as SCP in the intelligent network as attaching position register, mobile services switching centre and Visited Location Registor (MSC/VLR) can be used as SSP, and GMSC (gateway mobile switching center) and Visited Location Registor (GMSC/VLR) also can be used as SSP; Realize GSM network insertion intelligent network in second step, GSM network and intelligent network are supported the intelligent network business that some are public mutually.GSM network insertion intelligent network is realized by the No.7 signaling network.
Bluetooth technology is to belong to the technology that short-distance wireless inserts, and in 10~100 meters scope, supports the voice-and-data transmission of low rate at radius.Along with popularizing of Bluetooth technology, increasing portable terminal has been equipped bluetooth module, the intercommunication interconnection of support and bluetooth access device.A lot of personal users have also installed the Bluetooth phone gateway of supporting the bluetooth access function, i.e. babyphone gateway at home.The portable terminal of bluetooth-enabled module can be the same with the extension set of cordless telephone, be linked on the Bluetooth phone gateway, call out to PSTN (PSTN, the Public Switched TelephoneNetwork) switch of outside by Bluetooth phone gateway.In this case, though the user uses portable terminal (as mobile phone) to dial, the actual circuit that takies is the pstn telephone circuit, than cheap many of the price of using the mobile network to converse.In addition, the electromagnetic radiation of bluetooth is little more a lot of than the electromagnetic radiation of cellular network, and the healthy of user is beneficial to.
At present, a kind of calling line number technique for displaying based on mobile intelligent net has appearred, after portable terminal makes a call by Bluetooth phone gateway, mobile intelligent network can be discerned this calling, and the calling line number in the modification call signaling is the Mobile Subscriber International ISDN Number of portable terminal from the PSTN number translated with calling line number.When the called subscriber received incoming call, what show on the phone was calling subscriber's portable terminal Mobile Subscriber International ISDN Number, rather than the PSTN number of Bluetooth phone gateway.
Fig. 1 is in the prior art, the scene schematic diagram that portable terminal makes a call by Bluetooth phone gateway.Fig. 2 is under the scene shown in Figure 1, the flow chart of calling line number display packing.Referring to Fig. 1 and Fig. 2, method shown in Figure 2 may further comprise the steps:
Step 201, calling subscriber's Bluetooth mobile terminal equipment (calling UE) is to called subscriber's request of making a call, and this calling sends to Bluetooth phone gateway with the form of SETUP message.
Be the bluetooth carrying between calling UE and the Bluetooth phone gateway, the hello protocol stack is the cordless telephony profile stack of bluetooth standard, and the form of the called line number information field of call request is: access code+command code+extension number+real called number.
After step 202, Bluetooth phone gateway are received the call request of calling UE, with the form of initial address message (IAM, Initial Address Message) to the PSTN of this locality switch (PSTN-LS) request of making a call.
Called line number information field in the IAM call request in this step comprises access code, extension number and called subscriber's genuine number.Access code is used to route the call to the signaling service point; Extension number is used to identify the portable terminal of current calling, i.e. calling UE.When portable terminal when Bluetooth phone gateway is registered, Bluetooth phone gateway distributes an extension number for this portable terminal, and this extension number is registered on the signaling control point of network side and stores.
Step 203 after PSTN-LS receives the call request of Bluetooth phone gateway, is resolved the called line number information field of receiving, and is routed the call to signaling service point GMSC according to the prefix of access code.
Step 204, after GMSC received the call request of PSTN-LS, to the signaling control point of intelligent network, promptly SCP sent in Initial Detection Point (IDP, Initial Detect Point) message, this message and has comprised calling line number and called line number.Calling line number is the PSTN number of Bluetooth phone gateway, and the called line number is made up of extension number and called number.
Step 205, after SCP receives IDP message, called line number information field is resolved, the number of calling line is changed to the Mobile Subscriber International ISDN Number of portable terminal from the PSTN number of Bluetooth phone gateway, the called line number then changes to real called number.SCP returns CONNECT message to GMSC after finishing the calling line number change.
Step 206~step 208, GMSC receives after the CONNECT message, will send routing iinformation (SRI, Send Routing Info) and send HLR to, inquire about next step routing iinformation and called subscriber's UE at the roaming number of circuit domain (CS).HLR returns the SRI response message to GMSC, wherein comprise the E.164 address of the MSC (VMSC, GMSC) of calling UE place network, and called UE is at the roaming number of circuit domain.GMSC routes the call to MSC indicated in the SRI response message.Step and the present invention who calling is handled by MSC afterwards has nothing to do, no longer narration here.
By said process, the calling line number that shows at called party terminal is the Mobile Subscriber International ISDN Number of calling UE at last.
In scheme shown in Figure 2, SCP finishes the function of the calling line number number of changing, and has stored the relation of current PSTN number and extension and pairing Mobile Subscriber International ISDN Number among the SCP.At portable terminal at every turn by Bluetooth phone gateway after the called subscriber makes a call, the Mobile Subscriber International ISDN Number that calling line number is become portable terminal from the PSTN number translated of Bluetooth phone gateway that SCP can only fix.But the user sometimes wishes to show the Mobile Subscriber International ISDN Number of portable terminal to the called subscriber, sometimes wishes to show the PSTN number of Bluetooth phone gateway.For example, portable terminal is a kind of personal communication devices, Mobile Subscriber International ISDN Number belongs to user's individual privacy information, when the user uses the portable terminal that has bluetooth module to make a phone call by Bluetooth phone gateway, under a lot of situations just a part of machine as Bluetooth phone gateway use, do not want that the portable terminal Mobile Subscriber International ISDN Number that sticks one's chin out gives the called subscriber.
In sum, calling line number displaying scheme of the prior art, the Mobile Subscriber International ISDN Number with portable terminal that can only fix is shown to called party terminal as calling line number, thereby make the mobile phone users that makes a call by Bluetooth phone gateway, can not be chosen in the calling line number that called party terminal shows.
