Abstract

The call processing method based on user's individual number includes storing individual numbers and signed information of the users in PIHLR in the users' area; calling by the callee's area number plus the callee's individual number; and calling local user in local calling mode by the individual number directly to simplify the calling. In solving the problem of carrying number for shift to other area, there are no need for the network to provide PNHLR equipment and thus no secondary transmission in calling across area. The present invention can save cost in network construction and maintenance, simplify network and raise area-crossing calling efficiency and network stability.

Description

A kind of call processing method based on the individual subscriber number

Technical field

The present invention relates to the call processing method in a kind of communication network.

Background technology

Growing along with the communication technology makes the user of communication system increase sharply.For the user of communication system, all be endowed a network number that is used to distinguish other users.Each user's network number and other CAMEL-Subscription-Information all are stored in the network equipment of the similar attribution server of system into, and as calling out when taking place, system takes out user's CAMEL-Subscription-Information and finishes continuing of calling from the said equipment.

Because the region of communication system restriction, user's network number only has uniqueness in this area usually, information such as network number also are stored in the local attribution server usually, like this, have just produced the difference of call charging and the inconvenience that the user uses network number.For example, when local call takes place, adopt lower local telephone expenses canonical statistics telephone expenses, and when the strange land calling takes place, adopt higher long-distance telephone expenses canonical statistics telephone expenses.And when the user was moved to another area from an area, user's number also needed change, and promptly the network number in purpose area is applied for and be assigned with to the network number of discarded original area again.Obviously, the change meeting of the number inconvenience that brings a lot of numbers to use to the user.

For addressing the above problem, there is a kind of call processing method to realize carrying of Subscriber Number at present by Call Forwarding Unconditional.This method is, supposes that the original network number of user is A, needs network number is changed to B after the migration of area, when the calling that takes place phone A, automatically, unconditionally will insert Call Forwarding and arrive number B.The not discarded original number A of this method, but this method need take two number resources; And above-mentioned Call Forwarding is owing to the position fixing process that relates to from original area's network to the purpose LAN, and commentaries on classics expense before therefore need paying has increased the weight of user's burden.

The problem of above-mentioned Call Forwarding can solve by adopting the personal number technology.Personal number is the number with network uniqueness that the user obtains by application, like this, even the migration in area takes place in the user, by user's CAMEL-Subscription-Information such as personal number are transferred to the attribution server in purpose area from the attribution server of original area, the information that just can obtain this user by the attribution server in purpose area continues to use user's personal number.The implementation procedure of personal number technology is normally: at first the personal number to the user carries out stores processor, and userspersonal information (UserPI) attribution server (PIHLR) and individual subscriber number (UserPN) attribution server (PNHLR) are provided in this locality.When the user applies personal number, make comprise in the personal number of distributing to the user under user PNHLR numbering and this PNHLR in order to distinguish unique sequence number of different user personal number under the same attribution server; In user applies and after obtaining personal number userPN, this number is kept at deposits among the PIHLR in the individual subscriber number and the individual subscriber CAMEL-Subscription-Information table of comparisons; Also be kept at simultaneously in the table of comparisons of the individual subscriber number UserPN that deposits among the PNHLR and user PIHLR numbering.Be in same ownership place S owing to deposit the PNHLR of UserPN with the PIHLR that deposits user UserPI, when the user does not move, the numbering of PNHLR in the individual subscriber number is the PNHLR numbering of this ownership place, and the PIHLR of individual subscriber number correspondence also is the PIHLR numbering of this ownership place in this PNHLR; When migration had taken place the user, the userspersonal information had been moved among some PIHLR of relocation site D1; User's personal number still is retained among the corresponding PNHLR of former ownership place S, but in the PNHLR of former ownership place S, the pairing PIHLR numbering of individual subscriber number is modified to the numbering of the corresponding PIHLR of relocation site D1.Above-mentioned PNHLR and PIHLR have unique numbering in network.

Based on above-mentioned processing, when the call treatment of carrying out based on the individual subscriber number, no matter be that call out in local call or strange land, all need personal number according to the user to arrive first the PIHLR numbering of obtaining storing user subscription information among the PNHLR of former ownership place, navigate to the current CAMEL-Subscription-Information of depositing the PIHLR of user signing contract information and obtaining the user according to this PIHLR numbering again, thereby finish continuing of calling.

The shortcoming of said method is, must in network, set up PNHLR, simultaneously, must locate the CAMEL-Subscription-Information that just can find the user by secondary, therefore said method has not only increased the complexity and the construction cost of networking, call out the time of finishing but also prolonged, promptly reduced calling efficient and influenced percept of call completed.

Summary of the invention

The object of the present invention is to provide a kind of call processing method, use this method, when the migration that realizes personal number is carried, can improve the connection efficient that call out in the strange land, reduce the network complexity of this method of use based on the individual subscriber number.

For achieving the above object, provided by the invention

(herein with reference to claim)

Because the present invention only needs network according to the PIHLR of its own rule for its personal information of user's designated store, when bid, directly locate PIHLR by the network management rule according to user's personal number, can obtain user's CAMEL-Subscription-Information and finish continuing of calling, compare with the existing method that can realize that the personal number migration is carried, do not need network that PNHLR is provided equipment, can save networking and maintenance cost, reduction network complexity thus; And, owing to can one-time positioning arrive concrete PIHLR, avoid the secondary switching process in the calling of existing method strange land, improve the strange land and called out efficient and network stabilization.

Embodiment

The prerequisite of institute of the present invention foundation is that network provides the personal number with network uniqueness for the user, and in other words, in network, no matter where the user is in the network, can use this personal number and user to call out.Therefore, the user at first obtains such personal number by the network application, by network the personal number with network uniqueness of user applies acquisition and this user's CAMEL-Subscription-Information is stored in personal information (UserPI) attribution server (PIHLR) of user ascription area then.If the personal number that the user obtains is to deposit network first in, be that the user is promptly storing this personal number after the application in network, then the selected personal number application of user ground is its ownership place, at this moment, user's personal number together with other CAMEL-Subscription-Information of user in the PIHLR of this ownership place, i.e. network selected one of them PIHLR storage user's in the PIHLR of ownership place personal number and this user's CAMEL-Subscription-Information.Described user's CAMEL-Subscription-Information is meant, the CAMEL-Subscription-Information relevant with the individual subscriber number.Along with the evolution of operation way, this CAMEL-Subscription-Information also can comprise the CAMEL-Subscription-Information of the network terminal, such as the roaming of mobile phone, and trunk call authority of fixed line or the like CAMEL-Subscription-Information.

If the ownership place migration takes place in the user, suppose that the user moves to destination homing ground D from former ownership place S, because user's personal number has the network uniqueness, just user's personal number also can be moved to D ground from S ground, just change the ownership place of individual subscriber number, so just may use user's personal number calling party.Say so the in essence storing process again of personal number of the migration of described individual subscriber number promptly changes the PIHLR of storage individual subscriber number and relevant CAMEL-Subscription-Information.Therefore when the migration of number takes place in the user, during the personal number of the selected once more ownership place storage of user just, network need judge whether the new ownership place of selecting of user is identical with former ownership place, if it is identical, do not carry out new storage operation, otherwise carry out new storage operation, in the PIHLR of ownership place D, select a PIHLR storage user's personal number and CAMEL-Subscription-Information thereof.

For guaranteeing to validity based on the individual subscriber number call, above-mentioned new storage operation is meant by network selected one of them PIHLR storage user's in the PIHLR of the ownership place that the user newly selectes personal number and this user's CAMEL-Subscription-Information, personal number and this user signing contract information of this user of deletion in the corresponding PIHLR of former ownership place simultaneously.So just guaranteed uniqueness based on the individual subscriber number call, the inconsistent situation of user profile data can not take place, and no longer occur, S ground user does not add area code and calls out this user mistake invalid phone situation that continues again, and other local user error ground adds S ground area code and calls out this user, and network is the continue situation of invalid phone of mistake again.Certainly still better way is, in a period of time after the migration, network gives prompt tone to the defective ringing of above situation again, and the prompting calling subscriber has calledly been moved to D ground, and informs the regional number on D ground simultaneously.

Need to prove, when the selected new ownership place of user is stored its personal information, also can not delete the user profile of user storage in former ownership place PIHLR fully, how personal number that to be convenient to the user is like this using simultaneously, carry out the situation of strange land office such as user's cross-region, certainly, this situation possibly the user overpay expense.In practice, for preventing that the storage resources that a user takies network too much from not using, the mode that can take to limit the number of the ownership place of storing personal information for the user solves, also can when the user newly selects ownership place, point out its stored information of nullifying other ownership place, not want the Internet resources that use with minimizing Internet utilization fee usefulness, release user.

From the above, because the memory location before and after the migration of individual subscriber number, the location of promptly storing the PIHLR of individual subscriber number is determined by network fully, it doesn't matter with the formation of personal number, therefore, can include only a sequence number that the overall situation is unique distributing to individual subscriber in described user's the personal number.Be only to comprise sequence number in user's the personal number, and do not comprise facility information, the network information, and area information, although may comprise out of Memory in the sequence number, such as, actual carrying out number when planning, can carry out the distribution of numbering head by provinces and cities, the numbering head of feasible number of opening an account is one of several numbering heads of regulation with opening an account.

When setting up calling, under the local call mode, the calling subscriber directly uses called subscriber's personal number to call out the called subscriber; Under the method for calling of strange land, the personal number that the calling subscriber uses the regional number of called subscriber's ownership place to add the called subscriber is called out the called subscriber.

The invention will be further described below in conjunction with accompanying drawing.

Suppose PIHLR in the network according to scattering tree tissue, the leaf node in the corresponding scattering tree of PIHLR is with reference to figure 1.Fig. 1 has described the institutional framework of the PIHLR of ownership place, and the quantity of PIHLR and position are dynamically adjusted by network according to the individual subscriber number of the PIHLR storage of this ownership place and the size of CAMEL-Subscription-Information amount among the figure.For example deposit in the process in users personal data, the pairing PIHLR1 of leaf node corresponding in the if tree has reached the place capacity warning line, can not increase new user profile this moment again in this PIHLR1, consider rule, handle according to data-moving, PIHLR dilatation and the disassembly principle of the PIHLR of rule predetermining according to scattering tree.Certainly the userspersonal information of storage more also can carry out the merging of PIHLR according to management principle in the scattering tree.No matter how the leaf node in the scattering tree is adjusted by network, the location that can realize PIHLR according to user's personal number according to the rule of the PIHLR of network.

Personal number and the CAMEL-Subscription-Information of supposing the user are stored among the PIHLR shown in Figure 1, if local call takes place, its call proceeding flow process is with reference to figure 2.Fig. 2 directly uses called subscriber's personal number to call out the flow process of called subscriber's local call mode.

For the local call mode, if the calling subscriber is a landline telephone, then:

When network receives calling subscriber's calling, network thinks that the caller location is called ownership place, so, in the scattering tree of step 1 according to this locality, the on-site scattering tree of caller just, personal number according to the called subscriber, by computing step by step, one-time positioning is to the positional information of PIHLR of this called party information of storage, then at step 2 this PIHLR of location information access according to PIHLR, carries out query manipulation in step 3 according to called subscriber's personal number by PIHLR, at this moment, if called subscriber's ownership place just in the caller location, then, can be discovered and seized called subscriber's individual CAMEL-Subscription-Information; Otherwise, if called subscriber's ownership place not in the caller location, is then inquired about the individual CAMEL-Subscription-Information less than the called subscriber, call failure.PIHLR feeds back to network after inquiring called subscriber's individual CAMEL-Subscription-Information, finishes call proceeding in step 4 according to above-mentioned called subscriber's individual CAMEL-Subscription-Information by network.

For the local call mode, if the calling subscriber is a mobile phone, then:

If caller is not roamed, network thinks that the caller ownership place is called ownership place, and processing mode and caller are that the situation of landline telephone is similar.If caller is roamed, then when network receives calling subscriber's local mode calling, network thinks or thinks that the ownership place of caller is called ownership place, think that the current roaming place of caller is called subscriber's a ownership place, or network is directly stipulated, the mobile phone that roaming takes place can not carry out the calling of local mode, directly returns call failure information.When supposing the caller roaming, network thinks that the roaming place of caller is called ownership place, then network is in the scattering tree of step 1 according to the roaming place, personal number according to the called subscriber, by computing step by step, one-time positioning is to the positional information of the PIHLR of this called party information of storage, and the step of back and caller are that the situation of landline telephone is similar.

Call out if the strange land takes place, its call proceeding flow process is with reference to figure 3.Fig. 3 is to use called subscriber's ownership place to add the flow process that called subscriber's personal number is called out the called subscriber regional number

For the strange land method of calling, when called out in the strange land that network receives the calling subscriber, network thought that called subscriber's ownership place is when calling out, and added regional number decides.Therefore the regional number before step 11 is according to called subscriber's personal number is located the attribution server location of its CAMEL-Subscription-Information of storage, it is called subscriber's ownership place, and the scattering that obtains called subscriber's ownership place is set, in the scattering tree of step 12 according to called ground, personal number according to the called subscriber, by computing step by step, one-time positioning is to the positional information of the PIHLR of this called party information of storage, then at step 13 this PIHLR of location information access according to PIHLR, carry out query manipulation in step 14 according to called subscriber's personal number by PIHLR, the individual CAMEL-Subscription-Information that obtains the called subscriber feeds back to network, finishes call proceeding in step 15 according to above-mentioned called subscriber's individual CAMEL-Subscription-Information by network.

For caller is the situation of landline telephone:

Usually, when this caller is in dialed field, can adopt the local call mode to call out, otherwise, when this caller during, must adopt the strange land method of calling to call out not at dialed field.

For caller is the situation of mobile phone:

Usually,, when promptly being in called ownership place, can adopt the local call mode to call out, otherwise caller must be adopted the calling of strange land mode not when dialed field if not roaming of caller is then the same with the landline telephone method of calling; If caller is roamed, can there be three kinds to handle the situation of calling out, one, the user who only dials caller ownership place personal number can adopt the local call mode to call out, and dials caller ownership place any personal number in addition, all adopts the strange land method of calling; Two, only dial the on-site personal number user of caller current roaming and can adopt the local call mode to call out, dial caller roaming location any personal number in addition, all adopt the strange land method of calling; Three, dial any personal number, all must adopt the strange land method of calling.

Need to prove, in any case, can use the strange land method of calling to call out the called subscriber.Use the strange land method of calling, the mode of promptly using called subscriber's ownership place zone number to add called subscriber's personal number is called out the called subscriber, and the flow process of pairing call flow and Fig. 3 is similar.Certainly, for the calling that can adopt the local call mode to carry out originally, and the calling of having adopted the strange land method of calling to carry out, to the not influence of chargeing.

The regional number of supposing an area is 100.If a certain user's who opens an account in this area number is 66688899, then this user of local call, can directly dial 66688899 or 010066688899, dial this user, then need dial 010066688899 (wherein call out in " 0 " of front expression strange land) in other area; When user ascription area is moved to D ground, suppose that D ground regional number is 755, this Subscriber Number 66688899 does not need change, then D when dialing this user, can dial 66688899 or 075566688899, when this user is dialed in the area beyond on D ground, then need dial 075566688899.Like this, do not add regional number, then network based caller type if call out, be that caller is landline telephone or mobile phone, and caller is when being mobile phone, and whether the information of home location that roaming decides the called subscriber has taken place, and and then orient the PIHLR of storage called user information; Add regional number if call out, then at the PIHLR of location, the area storing subscriber information that regional number is represented, therefore, no matter where the user moves to, as long as know the area at its place, can finish calling by its personal number.Clearly, call out the strange land that the mode add the territory area code more helps personal number and carry, with the difference that the number that does not add regional number carries, only show that the strange land is called out on.
