Description
Technical field
The present invention relates to the landline telephone priority business of telecommunications network, particularly a kind of method and system that realize fixed telephone priority business.
Background technology
Cross-net call shifts
It is the business that telecommunications network often uses that call is shifted, its realize principle be by fixed switch or mobile attaching position register (Home Location Register is provided with transferring data in HLR) and realizes that its operation flow is as follows:
The user will use Call Forwarding services must arrive first the business hall application, and this is a service authorization.
After changeing authority before the user possesses, use this business, also need to register by phone.Mobile phone can directly be finished in the menu function of mobile phone; The pattern register of landline telephone: * 57* telephone number #.
The process of user's registration is actual to be to tell what purpose phone when fixed switch/mobile HLR " transfer on ", i.e. the destination address of trigger condition of Zhuan Yiing and the transfer of triggering back.The trigger condition that shifts has: unconditional, meet busy and three kinds of no responses.Trigger condition and trigger in the internal memory that the destination address that shifts the back is kept at fixed switch or mobile HLR is till the user cancels calling transfer.
For example, user A has applied for the business of calling forwarding on busy, and user A:13 has registered on the phone of oneself, and meeting hurries goes to user B:7654321.When certain customer call A:13, if user A:13 converses, then from HLR, obtain the destination address B:7654321 that will shift of registration, and make a call to this destination address user, behind party B-subscriber's off-hook, (Mobile Switching Center MSC) is switched to the purpose user of calling transfer, incoming subscriber and party B-subscriber's conversation in mobile switching centre.Because be to carry out calling transfer between the difference net, therefore speech will relate to the problem of gateway exchange, as shown in Figure 1 from a network transmission in another net.
This calling transfer needs the user A register call transfer service of opening an account in the business hall, when using this business, the object B of calling transfer is set: 7654321 on this phone A:13 at every turn.When certain customer call party A-subscriber, its speech channel be MSC-mobile gateway office-fixedly gateway exchange-MS (Mobile Station, board)-LS (Local Switch, local switch)-user B:7654321
The fixed telephone priority business scheme that Intellight network mode is realized
The realization principle of the fixed telephone priority business (during roaming) that Intellight network mode is realized is: for any fixedly calling subscriber the mobile subscriber is called out, and the mobile subscriber is when roaming into other cities, its route can change.Under the normal roaming condition, speech channel be from shared switched telephone PSTN fixedly gateway exchange-enter the mobile toll switch of gateway exchange---〉that moves in the Public Land Mobile Network PLMN---to the mobile phone user, shown in dotted portion among Fig. 2; And when adopting the intelligent network fixed telephone priority business, its signalling route is: fixing gateway exchange SSP (Service Switching Point, Service Switching Point)---〉reports to fixedly toll switch of SCP (Service Control Point, service control point)---〉with mobile number---〉call out the MS change over to; The traffic route is from the fixing toll switch of the fixedly gateway exchange---〉of shared switched telephone PSTN---〉call out the purpose fixed line that changes over to, and shown in the part of the solid line among Fig. 2.
This business will be passed through following steps before using:
1) registration of opening an account: promptly register and open this professional mobile phone or base to the business hall;
2) the professional use registered: in the time of will using this business, do the registration of this business on corresponding mobile phone and base at every turn;
3) the professional use cancelled: when variation has taken place in the cellphone subscriber position, when perhaps the cellphone subscriber is reluctant to use this business, can cancel this business.
Though the cross-net call transfer techniques has solved and has moved/fixing Call Forwarding problem, can satisfy the business demand of user to calling transfer preferably, has made things convenient for the user.But have following shortcoming:
1) existing scheme mainly is to solve the problem that called moving/fixing transfer is breathed out, be that calling transfer is to put on other purpose terminals carrying out transfer apparatus on the terminal called, the setting of this transfer can not be carried out by the purpose terminal, therefore, the control of fixed line can not be realized mobile calls;
2) rate problem: to transfer to fixedly be to do setting on the MSC in mobile network owing to move, and therefore, price policy remains by the mobile network decision, and the expense of present calling transfer is 0.2 yuan/minute, its present charge situation as shown in Table 1:
Table one
| Local | Roaming | ||
| Inside the province | Between province | ||
| Called mobile phone is directly answered | 0.40 unit/minute | 0.50 unit/minute+0.07 yuan/6 seconds | 0.60 unit/minute+0.07 yuan/6 seconds |
| The called mobile phone calling transfer | 0.20 unit/minute | 0.20 unit/minute+0.07 yuan/6 seconds | |
| Fixed telephone priority business (hypothesis) | 0.10 unit/minute | 0.10 unit/minute+0.07 yuan/6 seconds | |
By above form as can be seen: the mobile subscriber is when receiving calls, no matter be in this locality or roaming condition, also no matter be directly to answer or calling transfer, rate all are quite high.If the fixed line carrier not only can reduce user's rate, and can bring benefit to the fixed line carrier by adopting fixed telephone priority business and adopting suitable price policy.
3) problem of radiation: answering calling with mobile phone and always have radiation, is to reduce the radiation of mobile phone if adopt the mode of base switching.
Though the fixed telephone priority business that Intellight network mode is realized has advantages such as flow process is flexible, charging is flexible, capacity is big; But because all are called for the calling of 13XXX all is routed to intelligent network, require the disposal ability of intelligent network to be eager to excel (relatively 9), it is high that stability is wanted, and dispose the minicomputer of high-performance, high stability, invests bigger.
