Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below be example and with reference to accompanying drawing with code division multiple access (CDMA) core net and soft switch, the present invention is further elaborated.Under global mobile communication (GSM) core net also is identical principle.
Method provided by the invention has embodied the fusion thought that mobile phone and landline telephone are integrated, promptly be exactly with landline telephone when mobile phone manages, solved the difficult problem that landline telephone moves technically in network-wide basis.
The present invention is provided with comprehensive SHLR (SHLR, Synthesis Home Location Register), being used for will disperseing to be stored in the user data with the landline telephone binding in each fixed network switch concentrates and leaves among the SHLR of setting, and in the full communication net, set up or eliminate binding relationship between TLDN and the landline telephone flexibly, thereby landline telephone is considered as fixed-site and the mobile phone of line is arranged, the user can realize with using the same roaming of mobile phone by the corresponding relation of change in SHLR with the TLDN of its binding, authentication, the process that activates and deactivate.The user data of the whole network landline telephone is stored in SHLR, can also be accomplished the calling controlling mechanism of the whole network landline telephone and the unification of user data maintenance management.
Fixed telephone subscriber's data in the SHLR storage have: user's mobile number approaches the physical port number of number, the current use landline telephone of user, promptly in the CDMA core net, physical port number is electronic equipment sequence number (ESN), user's the international mobile station equipment identity (IMSI) and the TLDN number of the current use landline telephone of user.Wherein, consisting of of the thin number of mobile number: national code+SHLR number or area code+user's telephone number; IMSI consists of: Gu Mobile Country Code MCC+network No.+SHLR number or area code+user's telephone number; Consisting of of TLDN number: the user uses the exchange plane No.+user at the current place of landline telephone to use the physical port number of landline telephone.
The present invention is with the binding relationship of fixed telephone subscriber's data and landline telephone, this user's calling authority and the current state of roaming landline telephone, it is user's signing service data set (PROFILE) that user's subscription data directly adopts code division multiple access (CDMA), user PROFILE is stored in this user's of administration the VLR Visitor Location Register (VLR), in order to TLDN number and this user's signing service that shows the current binding of this user.
Owing to stored user data, so when the user wants telephone-moving, when promptly carrying out the fixed line services of roaming, a needs is bound this user's Subscriber Number again with the current TLDN number of wanting the shift position and got final product at SHLR.
As shown in Figure 1, Fig. 1 is the location registers flow chart of the present invention when carrying out the fixed line services of roaming, this entity that carries out location registration comprises: the SHLR of the switch (Softx) of the IAD of the landline telephone that the user will roam into (AG), administration AG and storage fixed telephone subscriber data, and its concrete steps are:
Step 100, Softx send to AG and revise (Modify) order, promptly set up a terminal (termination) in null context, wait for the off-hook event of landline telephone;
After step 101, AG receive this Modify order, send response (Reply) message of this Modify order to Soffx;
After step 103, Sofix receive this Notify order, send the Reply message of this Notify order to AG;
Step 104, Softx send the Modify order to AG, wait for the calling number of this landline telephone of input;
After step 105, AG receive this Modify order, send the Reply message of this Modify order to Softx;
Step 106, user carry out location registers operation, and its mode realizes by dialing a string operation command code, as the order number of dialing is " * location registers command code * Subscriber Number * authentication password * current time # ", then represent location registers; When the order number of dialing is " * deactivation log-on operation sign indicating number * Subscriber Number * authentication password * current time # ", then expression deactivation; The order number that AG dials this user is carried in the Notify order and sends to Softx;
After step 107, Softx receive this Notify order, send the Reply message of this Notify order to AG;
Step 108, Softx sub-argument from this calling number and user cipher goes out command code, Subscriber Number number, authentication password and current time, initiate authentication request (AUTHREQ) to SHLR, this authentication request comprises this Subscriber Number, authentication password and current time;
Softx can judge that this time Notify order is the location registers order, initiates authentication request to SHLR then according to command code;
Softx can also judge that this time Notify order is deactivation command, initiates authentication request to SHLR then according to command code;
User cipher, key and the current time of storing this user when the SHLR basis is opened an account calculate an authentication password, compare with the authentication password in the authentication request, if identical, then authentication is passed through, if inequality, failed authentication then, location registration failure this time;
Step 110, Softx receive authentication by after the message, and Softx initiates location registration to SHLR, should comprise the physical port address information of roaming landline telephone in the location registers message;
Step 111, SHLR revise the TLDN of the current use landline telephone of self storing of this user, and this user's PROFILE is sent to Softx, and Softx is stored in this user's PROFILE among the VLR;
After step 112, Softx location registers finish, send the Modify order, promptly send the verbal announcement of location registers success to the user by AG;
Location registers command code of the present invention and deactivation log-on operation sign indicating number can be stipulated by operator as required voluntarily.Subscriber Number is exactly a user's telephone number, can be " 00+ national code+area code+Subscriber Number " or " 0+ area code+Subscriber Number " form, also can be " 00+ national code+mobile subscriber number " form, and specifically what form is stipulated by operator.Authentication password produces as the MD5 algorithm by certain cryptographic algorithm, and (A-KEY) is relevant with current time, user cipher, user key.
The location registers that the present invention carries out the fixed line services of roaming can be divided into manual position registration and automated location registration two big classes.
When the automated location registration of carrying out the fixed line services of roaming, can adopt mode for dialer.The landline telephone that the present invention will roam to the user provides one for the dialer device, and will be somebody's turn to do for the dialer device serial connection on the subscribers feeder of landline telephone.Store A-KEY in this dialer in generation and be used for the clock of timing, the time that clock shows among time that this clock is shown and the Softx guarantees in the deviation range of a permission, in 1 minute.The user will import user cipher in advance in for dialer, when carrying out location registers, triggering is for dialer, for dialer according to A-KEY, user cipher and current time, by a kind of cryptographic algorithm, as MD5, just can calculate authentication password, initiate to carry the authentication request of this Subscriber Number, authentication password and current time then automatically according to the process of step 106 for dialer.This mode does not need to revise the existing fixed phone, only needs on the subscribers feeder of landline telephone series connection this dialer to get final product in generation.
The present invention can also will treat that dialer is arranged in the landline telephone, at this moment only need store A-KEY and get final product, and clock can utilize the clock in the landline telephone, and the button of input user cipher can use the button of landline telephone, thereby reduces cost.
When the manual position registration of carrying out the fixed line services of roaming, can also adopt the mode or the WEB mode of " token card ".
When adopting the mode of " token card ", the landline telephone that the present invention will roam to the user provides the device of " token card ".Should store A-KEY and the clock that is used for timing in " token card " device, the time that clock shows among time that this clock is shown and the Softx guarantees in the deviation range of a permission, in 1 minute.The user imports user cipher in advance in " token card ", when carrying out location registers, click the button of " token card " compute authentication password, " token card " is according to A-KEY, user cipher and the current time of landline telephone, by a kind of cryptographic algorithm, as MD5, just can calculate authentication password, by user's dial mode of 106 set by step, on phone, dial, send the location registers order.The canceling position enrollment process similarly.This mode does not need to revise the existing phone of user, only need to add one cheaply " token card " get final product.
When adopting the WEB mode, the user is before carrying out location registers, log on the WEB website of local operator with Subscriber Number and user cipher earlier, inform that then the website will carry out in the future the time of location registers, obtain authentication password by this WEB website according to A-KEY, user cipher, location registers Time Calculation, then the user time of agreement by 106 the dial mode input location registers order of carrying authentication password set by step of roaming fixed line, initiate authentication request.
No matter which kind of mode the present invention adopts when carrying out the location registers of fixed line services of roaming, all is in order to produce authentication password.The user of each landline telephone has an A-Key, this A-Key be provide by operator and can not make amendment by the user, authentication password forms by this tlv triple of A-Key, current time, user cipher is carried out md5 encryption algorithm.Also preserved user's A-Key and user cipher among the SHLR, when SHLR calculates this user's authentication password according to A-Key, current time, user cipher, if the unanimity that this authentication password is sent up with the user, just expression is a validated user, and authentication is passed through.
The present invention utilizes the current time to be replaced by authentication random number, has avoided requiring fixed line to accept the problem of SHLR by the authentication random number of Softx transmission.
What need supplementary notes is, " token card " device or be to obtain by built-in clock for the current time in the dialer, pass through in order to guarantee authentication, the time unanimity that the time that must guarantee " token card " or show for the clock of dialer shows with the clock of SHLR, ERROR CONTROL within the specific limits.Certainly preferably deliver among the SHLR with " token card " or for the time in the dialer, judge that by SHLR this time is whether in error range, if in the permissible error scope, SHLR so just can solve the problem of clock synchronization just with this time compute authentication password.For further guaranteeing safety, user cipher also can be revised by interactive telephone phonetic at any time by the user.
Same, the user can also use the described flow process of Fig. 1 to carry out deactivation process, the command code difference in the number dialed of user only, SHLR removes the binding relationship of this Subscriber Number and current TLDN according to this command code, and indication Softx eliminates the Subscriber Number the stored binding relationship with current TLDN in VLR.
As the user of roaming fixed line when conversing as the calling subscriber, the off-hook dialing of user elder generation, Softx can know the physical port number of this user place landline telephone, can find this user's CAMEL-Subscription-Information then in the VLR, judges whether allow this customer call.If allow to call out, then Soffx receives the called number of this customer call, makes a call.Follow-up call flow is identical with mobile subscriber's call flow.
As the user of roaming fixed line during as the called subscriber, calling subscriber's Softx searches the Softx at this current place of called subscriber in the SHLR, return this called subscriber's TLDN number by SHLR, and then route the call to the Soffx at the current place of called subscriber, the VLR of the current place Soffx of called subscriber just can find the called subscriber according to " physical port number of landline telephone " that be included in the TLDN number, and connects phone.What have to note is, owing to be landline telephone, does not need the paging flow process in the called flow, is in idle condition as long as judge the landline telephone at the current place of called subscriber, just can be directly to the called subscriber make a call foundation, ring, signaling procedure such as reply.
For fixed line roamer's whole communication process is described, provide message related to calls flow process concrete between a switch and media gateway below, wherein interoffice signaling is example with BICC, and H.248 subscriber signaling to be example, and core net is that example describes with the CDMA core net.
