Abstract
In CDMA mobile communication network, mobile telephone proceeds various registering and signing process by substituting UIM ID for ESN. As same as ESN, the UIM ID data format is also a binary system array of 32 bit to make the CDMA network can support the users of machine-card separating and non machine-card separating type. For said method being compatible with standard PN4582, UIM card selects UIM ID or ESN according to identify position when executing CAVE calculation and registering signing process. An identify position is add in HLR convenient for businessmen to manage mobile telephone users.
Description
The present invention relates to mobile communication, especially relate to the CDMA wireless network.
According to the existing general ANSI-41 standard of cdma network, travelling carriage will be carried out registration, authentication process earlier when mobile phone power-on, and success back network provides subscribed services for this user.Network is providing for this user in the process of subscribed services, can be as required with require the user to carry out authentication.The kind of authentication comprises that the beginning exhales authentication, exhales tens kinds of authentications etc. eventually.In carrying out these registrations, authentication process, MIN and ESN are two parameters appearance as pairing.The core point of this registration, authentication process process is to compare two results at network side, these of two results utilize the Several Parameters (comprising MIN/ESN) that is stored in Home Location Register/AUC (HLR/AC), carry out the CAVE algorithm and obtain in HLR/AC; Another result utilizes the Several Parameters (comprising MIN/ESN) that is stored in the travelling carriage, carries out the CAVE algorithm and obtain in travelling carriage.If these two results meet set rule, then this user of network validation is a validated user; Otherwise network thinks that this user is the disabled user.
For the travelling carriage of separation between machine and card type, because the ESN of mobile phone is stored on the mobile phone, and user's MIN number storage is on the UIM card.Also be replaced with ESN that MIN matches mutually on the mobile phone if the user changes mobile phone, the change of ESN then makes authentication trouble occur thereupon, causes the authentication process of handling based on existing MIN/ESN pairing normally not carry out.
Though the development speed of mechanics of communication is very fast, up to now, realize under the IS-95A standard that in second generation mobile communication system the practical case of separation between machine and card does not also occur.Because being considered to difficult the realization, this kind machine-card separation method realizes comparatively trouble in other words, so CDMA development institution (CDG) originally plans can realize the separation between machine and card of cdma network in 3-G (Generation Three mobile communication system).But because of the unseparated present situation of cdma mobile communication net machine card has nowadays demonstrated its all drawback, as: use inconvenience, can not satisfy the needs in market etc., so for satisfying the demand in market, the CDMA development institution intends realizing in advance the scheme of CDMA net separation between machine and card.For this reason, Telecommunications Industries Association (TIA) has proposed standard P N4582 and has set forth its separation between machine and card embodiment based on mobile phone sequence number (ESN) and MIN mismatch, this scheme requires when each mobile phone shutdown to send to network removes registering signal, then send registering signal to network earlier during start, send the authentication signal again; The user's of network side Home Location Register (HLR) storage ESN is required to be a dynamic variable, check all when the registration each time of mobile phone whether ESN is a new numerical value, if new numerical value then needs to change this variable, make user's MIN and new ESN match, and then carry out authentication process.Though this scheme can realize the cdma mobile communication separation between machine and card, have following some weak point:
1, when each start, the time that the processing procedure of authentication takies after the registration is longer earlier.
2, in order to reach the purpose of ESN and MIN mismatch, the change of HLR is bigger, and it not only needs to do very big workload, but also needs the long time of cost.
3, the protocol modification to existing ANSI-41 network is bigger, and need do compatibility test to the equipment of different manufacturers, thereby causes the problem of development cost and development time increase again.
4, the influence that causes for Virtual network operator is very big, and Virtual network operator not only will increase investment, postpone the time that provides professional, and the workload of its later maintenance strengthens also.

In the HLR of cdma mobile communication net, add one and be convenient to sign position leading subscriber and that indicate user property.
After having adopted said method, the method in cdma mobile communication net realization separation between machine and card of the present invention has following advantage and effect:
1,, saves the network rebuilding time for cdma network operator reduces investment outlay.Because this method is based on the alternative ESN of the identifier (UIM ID) that utilizes the UIM card and goes to carry out registration, authentication, network side needs to do any change hardly can realize separation between machine and card, institute does not provide normal service so that cdma network operator both can develop separation between machine and card type user and also do not influence simultaneously for existing non-separation between machine and card type user; Because network side needs to make any modification hardly, make Virtual network operator reduce dependence to the equipment supplier, reduced the line service amount; And because all information of identification user all are stored on the UIM card, Virtual network operator can also carry out before some because the business that can not carry out soon the dependence of mobile phone ESN, as prepayment service.
2, make CDMA network facility supplier save development cost and time, can be very fast for cdma network operator provides equipment, dominate the market as early as possible.In the present invention, UIM is stuck in when carrying out the CAVE algorithm can select UIM ID or ESN according to set sign position, and this sign position is write by operator, gives the CDMA operator that adopts different schemes (based on PN4582 standard or the scheme based on UIM ID of the present invention) to realize separation between machine and card so same card can be sold by UIM card vendor.
3, the selection of more portable terminal is provided for CDMA user; Simultaneously, because the driving of the market demand, the price of portable terminal will inevitably reduce, thereby has saved investment to portable terminal for the user again.
4, bring more rich profit for cdma mobile terminal supplier.On the one hand, CDMA user must provide the bigger market demand for cdma mobile terminal supplier to the increase of portable terminal demand.On the other hand, because whole personal information storage of CDMA user are on the UIM card, the user can arbitrarily change portable terminal, and the commercial networks that make cdma mobile terminal supplier be no longer dependent on CDMA operator are sold portable terminal, can open up new Sales Channel, increase sales volume.
Below, with specific embodiment the method in cdma mobile communication net realization separation between machine and card of the present invention is done further detailed description in conjunction with the accompanying drawings.
Fig. 1 is the schematic flow sheet of MAP of the present invention.
Fig. 2 is a schematic flow sheet of selecting parameter when the UIM card is carried out authentication process among the present invention.
According to existing ANSI-41 standard, in carrying out registration, authentication process, MIN and ESN are two parameters that occur as pairing.The core point of this registration, authentication process process is to compare two results at network side, and these of two results utilize the Several Parameters (comprising MIN/ESN) that is stored among the HLR/AC, carries out the CAVA algorithm and obtain in HLR/AC; Another result utilizes the Several Parameters (comprising MIN/ESN) that is stored in the travelling carriage, carries out the CAVE algorithm and obtain in travelling carriage.If these two results meet set rule, then this user of network validation is a validated user; Otherwise network thinks that this user is the disabled user.
Travelling carriage for the separation between machine and card type, because the ESN of mobile phone is stored on the mobile phone, and user's MIN number storage is on the UIM card, because the change of the ESN that matches mutually with MIN makes authentication trouble occur, the authentication process that causes existing MIN/ESN pairing to be handled can not normally carry out when the user changed mobile phone.The invention is characterized in that adopting UIM ID to substitute ESN carries out authentication and registration, like this, because the customer parameter of storage is user's UIM ID rather than a certain ESN in Home Location Register/AUC (HLR/AC), and UIM ID is stored among the UIM card, the user is to use UIM ID to carry out registration, authentication process under the situation of changing mobile phone, so can realize separation between machine and card.
Among the present invention, mobile subscriber's personal information is to be stored on the UIM card, as MIN, UIM ID etc.When network needed portable terminal to carry out registration, authentication, the UIM card was used the personal user information parameter that self stores, and carried out the CAVE algorithm as the SSD of MIN, UIM ID and current storage and the random number (RAND) that transmits from network side, obtained an authenticating result.Portable terminal sends to network to this result in company with user profile MIN, UIM ID.Simultaneously, this user's of network utilisation HLR/AC storage personal information MIN, UIM ID and current available shared private data (SSD), random number (RAND) are carried out the CAVE algorithm, obtain an authenticating result, at network side the result that this result carries out with this user's travelling carriage is compared, whether judge this user's legitimacy, be validated user promptly.
Among the present invention, adding one and indicate the position in the Home Location Register (HLR) of cdma network, is separation between machine and card type user or non-separation between machine and card type user to distinguish a certain user, so that the maintenance staff of network knows a certain attribute of user.
Because the present invention adopts UIM ID to substitute ESN to carry out authentication and registration, the cdma network side needs to do any change hardly just can realize separation between machine and card, and institute is so that adopt cdma network of the present invention operator can develop separation between machine and card type user and non-separation between machine and card type user simultaneously.If a certain user is separation between machine and card type user, one of personal user information parameter of then storing among the HLR/AC is this user's UIM ID but not ESN; If a certain user is non-separation between machine and card type user, one of personal user information parameter of then storing among the HLR/AC is this user's ESN but not UIM ID.
Because requiring the ESN (for non-separation between machine and card type user) of input when carrying out the CAVE algorithm is the binary sequence of one 32 bit, so in the present invention, requiring UIM ID also is the binary sequence of one 32 bit.UIM ID can distribute to CDMA operator, and concrete distribution condition can be decided according to the actual requirements.
Consider the existence of PN4582 standard simultaneously, so should be taken into account that the UIM card is to the compatibility of two schemes among the present invention.In order to reach the purpose of UIM card to two scheme compatibilities, the present invention is provided with one and indicates the position among the UIM card, R-UIM selects to import one of parameter according to this sign position when carrying out the CAVE algorithm be UIM ID or ESN, so make it both can be used for adopting the PN4582 standard to realize the cdma network of separation between machine and card, can be applicable to adopt method of the present invention to realize the cdma network of separation between machine and card again.This sign position is write by CDMA operator, because CDMA operator knows that the network that he runs is to adopt any scheme to realize separation between machine and card.
Below, with a specific embodiment, the process when promptly the CDMA mobile subscriber starts shooting registration, authentication is described content of the present invention in more detail.And the authentication process under other situation (exhale authentication as the beginning, exhale authentication etc. eventually) is similar to this flow process, at this, do not described one by one, but what need emphasize is in these authentication process processes, all to need to substitute ESN with UIM.
As depicted in figs. 1 and 2, the start shooting process of registration, authentication of CDMA mobile subscriber is as follows:
(1) UIM card (R-UIM card) is movably inserted mobile phone, mobile phone power-on, mobile phone sends ESN to R-UIM.
(2) R-UIM sends acknowledge message ACKN to mobile phone.
(3) mobile phone (ME) determines to have entered new service system from overall information, and all systems' accesses all require authentication (AUTH=1).The random number (RAND) that is used for authentication also should obtain at this moment, if do not have, travelling carriage (MS) replaces with null value.
(4) mobile phone sends random number (RAND) to R-UIM, and R-UIM carries out the CAVE program and produces a registration authenticating result (AUTHR) with SSD-A, UIM ID (selecting according to indicating the position), the MIN of random number (RAND) and current storage.
(5) R-UIM with AUTHR to mobile phone.
(6) mobile station MS is registered in new service MSC (MSC-S), and its MIN, UIM ID, AUTHR, call history counter COUNT and RANDC is provided.
(7) RANDC that is provided by travelling carriage (MS) is provided MSC-S, then sends authentication solicitation message (AUTHREQ) to new service VLR (VLR-S), comprising RAND.
(8) VLR-S sends AUTHREQ to Home Location Register (HLR).
(9) HLR sends AUTHREQ to AC.
(10) if SSD is present and another system is shared, AC will carry out " sharing the SSD authentication " (seeing the ANSI-41 standard), and directly jump to step (11);
If SSD is present and another system is not shared, AC will carry out the following step:
I, AC examine MIN and the UIM ID that is reported by travelling carriage (MS), and AC carries out CAVE algorithm generation registration authenticating result (AUTHR) with SSD-A, UIM ID, the MIN of RAND and current storage then;
II, AC judge whether the AUTHR that receives from MS meets the result that it carries out CAVE;
III, AC judge whether the call history counter COUNT that receives from MS is consistent with current value.
(11) AC sends authreq to HLR.
(12) HLR sends authreq to VLR-S.
(13) VLR-S sends authreq to MSC-S.
(14) after the success of travelling carriage (MS) authentication, MSC-S sends REGNOT to VLR-S.
(15) VLR-S sends REGNOT to HLR.
(16) if registered in another system before the travelling carriage (MS), HLR sends REGCANC to former service VLR (VLR-O).
(17) VLR-O sends REGCANC to former service MSC (MSC-O).
(18) MSC-O sends regcanc to VLR-O.
(19) VLR-O sends regcanc to HLR.
(20) HLR writes down the reposition of travelling carriage (MS) in memory, and sends regnot to VLR-S, comprising the information of VLR needs.
(21) VLR-S sends regnot to MSC-S.
Above-mentioned process when only being CDMA mobile subscriber mobile phone power-on registration, authentication, and the authentication process under other situation (is exhaled authentication as the beginning, exhale authentication etc. eventually), because of the flow process of the registration of its flow process and mobile phone power-on, authentication similar, and by those of ordinary skills according to the solution of the present invention and can drawing apparently within the scope of the invention, so described no longer one by one.
