Description
Technical field
The present invention relates to a kind of international roaming user and use local virtual number to realize the system and method for calling out, belong to telecom mobile network network value-added service technical field.
Background technology
At present, whole world mobile operator mainly adopts GSM and two kinds of mobile network's technology of CDMA to provide telecommunications service for the user, and the calling the when mobile subscriber roams between country variant often needs to pay expensive international long-distance and international roaming expense.From calling out the situation analysis of shared speech channel, even the user of roamer and its conversation is positioned at the network of same operator, the calling that has still needs elder generation's process international gateways and takies international speech channel to travel back across local network again, the continuation method of this calling has not only been wasted relay resource, and finally brings unnecessary long-distance and wandering fee for the user.
In existing GSM net, if the call flow when calling subscriber A dials the number that is international roaming user (another country) user B is as follows:
(1) calling subscriber A dials another national called subscriber B, needs to add before the number of user B the national code of dialling international long-distance access code and user B belonging country; For example: Hong Kong mobile subscriber 91111111 roams to Beijing, China's Mainland, during the user of this Hong Kong of Beijing customer call, need dial " 00-852-91111111 ".
The moving exchanging center MSC of (2) making a start is set up one section international long-distance speech channel with the gateway MSC of call proceeding to user B belonging country;
(3) this gateway MSC obtains the current roaming number of user B from the HLR of user B;
(4) this gateway MSC according to roaming number with call proceeding to the current on-site MSC of user B, set up one section international long-distance speech channel again, and the mobile phone of connecting subscribers participating B.
Therefore, according to this flow process, if user B roams to caller A current network at this moment, even caller A and called B are in consolidated network, also need set up two sections international long-distance speech channels, wherein calling subscriber A to pay from give orders or instructions to the international long-distance telephone expenses of called home network, and called subscriber B also will pay international long-distance telephone expenses and international roaming expense from its home network to its current visit net.For example above-mentioned Beijing customer call Hong Kong user's calling just comprises Beijing to Hong Kong and two segment lengths of Hong Kong to Pekinese way speech channel, Beijing user will pay the telephone charges in Beijing to Hong Kong and use, and this Hong Kong user will pay Hong Kong to Pekinese telephone charges usefulness, and corresponding international roaming expense.
Cause the reason of this situation to be: in present existing mobile telecommunications network, no matter be GSM network or cdma network, a SIM card is distributed a Mobile Subscriber International ISDN number (MSISDN, Mobile Station International ISDN Number), just each user can only have a MSISDN.If the user wishes to obtain local number in the roaming place, just must load onto local SIM card, and when using this this locality Mobile Subscriber International ISDN Number, insertion corresponding subscriber identification module SIM card (Subscriber Identity Module) in mobile phone terminal.If what the user used is the cell phone that can only insert a SIM card, at this moment the original number of user just can't use.And after the user returns home network, wish to use original Mobile Subscriber International ISDN Number, and then need original SIM card is replaced up, at this moment, the user just can not use at the number of the locality of roaming place application.
Simultaneously, the local user is when dialing roamer's phone, even roamer and local user are in same carrier network, calling out still needs elder generation's process international gateways and takies international speech channel to travel back across local network again, the continuation method of this calling has not only been wasted relay resource greatly, and connecting time is long, has finally brought unnecessary, expensive long-distance and wandering fee also can for the user.
