The method comprises the steps that access rules for allowing or rejecting the access of the 2G subscribers are set at a 3G network side; different mark information is respectively configured for the 2G subscribers and 3G subscribers; the 3G network side judges the subscriber type of subscribers according to the mark information of the subscribers; when the subscribers are 2G subscribers, the access of the 2G subscribers is controlled according to the access rules. By the present invention, 3G network operators avoid operating benefit loss caused by the optional access of the 2G subscribers, and the normal use of network resources of the 3G subscriber is avoided to be influenced.

Description

The method that the network control user inserts

Technical field

The present invention relates to the mobile communication technology field, relate in particular to the control method of mobile communications network the user access network process.

Background technology

At present, the transition mobile communication system (2.5G) of second generation mobile communication system (2G) that the public is using and 2G and 3-G (Generation Three mobile communication system) (3G) all mainly is to be used to provide voice communication service, though the 2.5G mobile communication system also can be carried data communication service, but the Data-carrying speed that is provided is lower, and provide service quality (QoS, Quality of Service) limited in one's ability can't be satisfied existing multimedia communication and the qos requirement of exhaling new business such as communicating by letter more.Therefore, growing along with data communication technology and multimedia communication technology, press for existing mobile communications network can provide polytype and service quality QoS is higher multimedia communication service and high speed data communication services, require existing mobile communications network can realize global seamless covering and roaming function simultaneously, with the mobile dream that whenever really is implemented in, any way communication is carried out in any place.Above-mentioned these demands have been satisfied to a great extent and improving the 3-G (Generation Three mobile communication system) (3G) in stage at present.

Increasingly mature and perfect along with the 3G standard technology, increasing operator takes up to dispose the 3G network of oneself; But at user side, owing to need to change portable terminal with 3G function, could insert the 3G mobile communication network, the use 3G network communicates, the huge 2G user's update all in short-term of current quantity is that 3G subscription exists certain degree of difficulty simultaneously, therefore 2G user and 3G subscription will occur and deposit at moving communicating field, and 2G mobile communications network and 3G mobile communications network and the situation of depositing.

For the 3G mobile communications network is set up in operator,, therefore when setting up 3G network, just need to introduce again the communication equipment that meets 3G standard because that 2G standard technique and 3G standard technology exist in itself is very big different.At first, the Access Network of 2G mobile communications network part partly realizes different with the Access Network of 3G mobile communications network; Secondly, in 2G network and 3G network, its operation principle of being responsible for the mobile switching centre (MSC, Mobile Switching Center) of mobile message exchange also has bigger variation, so operator is more prone to introduce new 3G switching equipment; The 3rd, at the 2G network in the variation of 3G network, for the attaching position register (HLR that is responsible for subscriber information management, HomeLocation Register) and (AUC of AUC, Authentication Center) operation principle changes less relatively, just in the 3G network system, increased some new business, and the stores processor of user profile mechanism and authentication process mechanism principle are basic identical; Therefore, in order to reduce networking cost, part operator is more prone to the HLR/AUC equipment in the original 2G network system is upgraded, and makes HLR/AUC equipment become the public function entity of 2G network system and 3G network system, the user profile that is used to manage and store whole 2G users and 3G subscription; Therefore, to preserve the international mobile subscriber identifier (IMSI of all 2G users and 3G subscription among the public HLR of 2G network system and 3G network system, InternationalMobile Subscriber Identity), location area information at authentication information, business information and mobile subscriber place (LAI, Location Area Identity) etc.

With reference to Fig. 1, this figure is 2G network and 3G network and the network configuration topological diagram deposited in the prior art.Owing to the difference of wireless access technology, the 2G portable terminal can only be linked into the 2G network system by the base station sub-system (BSS, Base Station System) 1 of 2G network system among the figure; The 3G portable terminal can be by the UMTS wireless access network (UTRAN of 3G network system, UMTS Terrestrial AccessNetwork) 4 is linked into the 3G network system, for the 3G portable terminal of some function compatibility, can also be linked into the 2G network system by the BSS 1 of 2G network system simultaneously.

In the 2G network system, comprise mobile switching center (MSC/VLR) 3 that is used to 2G user that the voice data exchange ability is provided and the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) 2 that data exchange capability is provided for 2G user; And in the 3G network system, comprise mobile switching center (MSC/VLR) 5 that is used to 3G subscription that the voice data exchange ability is provided and the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) 6 that data exchange capability is provided for 3G subscription.

The shared same HLR/AUC 7 of 2G network system and 3G network system so preserve 2G user's identification information, business information and authentication information etc. among this HLR/AUC 7, also preserves identification information, business information and the authentication information etc. of 3G subscription simultaneously.

And comprising user's authentication information, IMSI information etc. with user-dependent user profile, these have user-dependent information to be kept on the subscriber identification module that the user has, rather than preserve on the portable terminal; The user profile correspondence that is 2G user is kept in SIM (the Subscriber Identity Module) card, and the user profile correspondence of 3G subscription is kept in USIM (UMTS SIM) card.

After 2G user is inserted into self SIM card on the 2G portable terminal, in the process that inserts the 2G network system, the 2G network side judges that draw this 2G user is (be preserve on this user totem information, authentication information and this user's SIM card of preserving among the HLR/AUC 7 of network side information consistent) behind the validated user, and the 2G network system will allow this user access network; In like manner, if after 2G user is inserted into self SIM card on certain 3G portable terminal, in the process that inserts the 3G network system, the 3G network side is judged and is drawn this 2G user for behind the validated user, also can allow this 2G user to be linked into 3G network.

Yet, because the 3G network system is better than the service quality of 2G network system to a great extent, simultaneously because 3G network belongs to New-deployed Network, be bound to consider the problem of cost recovery, therefore operator is linked into the situation of 3G network system simultaneously at 2G user and 3G subscription, will certainly formulate different market strategies and expenses standard, and if 3G network allows 2G user to use the 3G portable terminal arbitrarily to insert 3G network, will cause following problem:

One, 2G user may avoid operator and use the expenses standard of high-quality 3G network resource at it, reduces the income of operator; Like this, when the 2G user who is linked into 3G network reached some, operator's loss in this respect will account for significant proportion, and especially in the 3G networking initial stage cost recovery stage, operator will can not accept the appearance of this phenomenon.

They are two years old, paid the expense of 2G network service quality as a large amount of 2G users, use but be the 3G network service time, will take a large amount of 3G network resources, especially at the 3G networking initial stage, the 3G network self-capacity is smaller, and therefore can seriously influence 3G subscription normally uses the 3G network resource, when a large amount of 3G subscriptions used owing to the service quality (QoS) of Internet resources is difficult to guarantee to withdraw from, the development of 3G network will be hindered.

In sum, in being about to the 3G network system of setting up, must have the function that the 2G user that inserts its network system and 3G subscription type are distinguished,, the 2G user who is linked into the 3G network system effectively be controlled with on the basis that can distinguish 2G user and 3G subscription type.

Summary of the invention

The technical problem to be solved in the present invention is to propose the method that a kind of network control user inserts, so that the 3G network system can distinguish the 2G user and the 3G subscription type that are linked into its network system, and, realize 2G user is linked into the control of 3G network based on differentiation to 2G user and 3G subscription type.

Embodiment

The method that network control user of the present invention inserts is applied to 3G network the 2G user who is linked into its network is controlled, and its design aim is at first to dispose different identification informations for 2G user respectively with 3G subscription; So that the location update request message of the user being sent at 3G network when handling, is distinguished this access user's user type according to the identification information that inserts the user; Obtaining in differentiation under the situation that this access user is 2G user, the access rules to 2G user that sets in advance in conjunction with 3G network allows or refuses this 2G user's access again, thereby reaches the purpose that 3G network is controlled 2G user's access.

At first with reference to Fig. 2, this figure is the simple realization flow chart of the method for network control user access of the present invention, and wherein the processing procedure of 3G network control 2G user access is specific as follows:

Step 10 is provided with the access rules that allows or refuse 2G user's access by the network management personnel in the 3G network side; When the access rules that allows 2G user's access was set in the 3G network side, 3G network was learning that inserting the user is under 2G user's the situation, can allow this 2G user to insert its network; And when the 3G network side was provided with the access rules of refusal 2G user access, 3G network was learning that inserting the user is under 2G user's the situation, can refuse this 2G user and insert its network.

Step 20 is respectively 2G user by operator again and distributes different identification informations with 3G subscription, respectively 2G user and 3G subscription are distinguished by this different identification information; Wherein can be by disposing the not international mobile subscriber identity of jack per line section (IMSI respectively for 2G user and 3G subscription, InternationalMobile Subscriber Identity), 2G user and 3G subscription are distinguished as the identification information of 2G user and 3G subscription with the IMSI that uses the difference section;

In addition, can also be by disposing the not mobile subscriber number of jack per line section (MSISDN respectively for 2G user and 3G subscription, Mobile Station International ISDN Number), 2G user and 3G subscription are distinguished as the identification information of 2G user and 3G subscription with the MSISDN that uses the difference section;

Except that top two kinds of configuration modes, can also distribute different user type identification codes with 3G subscription by being respectively 2G user, to use the identification information of different user type identification codes as 2G user and 3G subscription;

Wherein the IMSI number of respective user, Mobile Subscriber International ISDN Number or user type identification code are kept among the affiliated attaching position register HLR of user; And the user when access network to location update request message that network side sends or periodically in the location update request message that network side sends, generally comprise user's IMSI number, network side is in the process of process user location update request message, when the HLR registration location message under the user, the HLR meeting so according to user's IMSI number inquiry to Mobile Subscriber International ISDN Number or user type identification code that should the user, and Mobile Subscriber International ISDN Number or the user type identification code that inquires fed back to VLR Visitor Location Register VLR or the Serving GPRS Support Node SGSN that the user visits, thereby VLR Visitor Location Register VLR that the user visited or Serving GPRS Support Node SGSN just can distinguish this user's user type according to user's Mobile Subscriber International ISDN Number or user type identification code.

Step 30,3G network side just can be according to this user's of identification information judgment of this user user types in the location update request message process that process user is sent; Identification information as this user shows that this user is 2G user, and then this user type is 2G user; And show that as this user's identification information this user is 3G subscription, then this user type is 3G subscription.

Step 40 according to the processing procedure in the step 30, judges that drawing this user still is 3G subscription for 2G user, if judge that drawing this access user is 2G user, execution in step 50; If judge that drawing this access user is 3G subscription, then execution in step 60.

Step 50,3G network are according to the access rules to 2G user that sets in advance in the step 10, and decision allows or refuses this user and insert.

Step 60,3G network directly allows this 3G subscription access network judging that this 3G subscription is under the situation of validated user.

Wherein 3G network side location update request message that the user is sent is handled and is divided into following two kinds of situations:

1), then user's location update request message is handled by the function of exchange entity (CS, Circuit Switched) of circuit domain and the HLR under the user if the user is linked into the circuit domain of 3G network; And the function of exchange entity of circuit domain generally promptly refers to the service support node SGSN of GPRS packet communication subnet in the 3G network system;

2) and if the user is linked into the packet domain of 3G network, then user's location update request message is handled by the HLR under the function of exchange entity (PS, Packet Switched) of packet domain and the user; And the function of exchange entity of packet domain generally promptly refers to moving exchanging center MSC and VLR Visitor Location Register (VLR, Visitor Location Register) in the 3G network system.

With the function of exchange entity by 3G network lateral circuit territory the location update request message that the user sends is treated to example below, the method principle that network control user of the present invention is inserted is described in detail.At first the IMSI number of jack per line section is that example describes to distinguish 2G user and 3G subscription at distribute not respectively for 2G user and 3G subscription.With reference to Fig. 3, this figure is in the method that inserts of network control user of the present invention, with the IMSI number of the jack per line section not access control process schematic diagram as 2G user and 3G subscription identification information; The concrete processing procedure that its 3G network control 2G user inserts is as follows:

Step S1, the mobile subscriber sends location update request message (MM Location Updating Request) by the wireless access network UTRAN of 3G network to the MSC of roaming place, wherein carry this user's who preserves in its user's SIM card or the usim card IMSI number or the temporarily moved subscriber identifier (TMSI that previous access network distributes in the MM LocationUpdating Request message, Temporary MobileSubscriber Identity), and the location area information at this current place of user, wherein location area information comprises the LAI (Location Area Id, i.e. lane place ID) and the Cell ID (sub-district ID) at this present place of user.

Step S2, because the Access Network of 2G network and 3G network is different, the numbering that therefore just causes LAI and Cell ID in 2G network and 3G network is with different.Situation for 2G network and the shared MSC/VLR of 3G network, can dispose the corresponding 2G Access Network of which class LAI and Cell ID among the shared VLR, the corresponding 3G Access Network of which class LAI and Cell ID, it is that BSS by the 2G network inserts that thereby LAI that carries in the MM Location Updating Request message that the VLR of user roaming place just can send according to this user and the numbering of CellID are judged this user, and still the UTRAN by 3G network inserts.And for the MSC/VLR of individual responsibility 2G network or individual responsibility 3G network, can dispose MSC/VLR and only be responsible for the still only responsible 3G network of 2G network, it is the BSS access by the 2G network that thereby MSC/VLR also just can determine the user, and still the UTRAN by 3G network inserts.

Because the IMSI section that 2G user is corresponding different with 3G subscription, in MSC, (can certainly in VLR, dispose) and dispose the corresponding 2G user of which IMSI section, the corresponding 3G subscription (can certainly in VLR, dispose) of which IMSI section, MSC (or VLR) judges that according to this user's IMSI number this user is 2G user or 3G subscription, as being that 2G user and 3G network are set to refuse 2G user's access, then go to execution in step S11 feedback refuse information; As be set to allow 2G user to insert for 2G user and 3G network, execution in step S3 then.

If that carry in the MM Location Updating Request message that MSC/VLR receives is user's TMSI, MSC/VLR can obtain IMSI from the VLR of the previous access of this user or from its portable terminal.

Step S3, the MSC of user roaming place send the location area updating message (MAP Update LocationArea) of the IMSI number that comprises this user to the VLR of user visiting.

Step S4, the VLR response MAP Update Location Area message of user visiting, the location update message (Location Update Location) that sends the IMSI number that comprises this user is to the affiliated HLR of user.

Step S5, HLR detects the IMSI number that carries in the Location Update Location message, carry out the legitimacy authentication operations with identity to this user, if this IMSI number has record in the database of HLR, illustrate that then this user is a validated user, continue subsequent treatment, HLR is saved in user position information in the database simultaneously; Otherwise illustrate that this user is illegal user, HLR will not allow this user access network, and directly execution in step S9 sends refuse information.

Step S6, HLR send the visit VLR of the insertion subscriber data message (MAP Insert Subscriber Data) of all kinds of business information that comprise this user applies to the user.

Step S7, extract self unsupported business information in all kinds of business information that user's visit VLR comprises in MAP Insert Subscriber Data message, and self unsupported business information that will extract is encapsulated into and inserts in the user data response message (MAP Insert Subscriber Data Ack), and gives HLR under the user with MAP Insert Subscriber Data Ack message feedback.

Step S8, HLR is according to the unsupported business information of VLR that comprises in the MAP Insert Subscriber Data Ack message, draw VLR and do not support which business, and then whether unsupported business information decision is wanted so limited this 2G user and insert 3G network according to VLR.As advice of charge (charging) supplementary service (AOCC, Advice of Charge Charging supplementary service) be a kind of business that relates to charging, if the VLR at this 2G user of current roaming place does not support this business, HLR under possible this 2G user can not allow this user to insert 3G network, in order to avoid cause operator's telephone expenses loss.

Step S9, HLR determine allow or refuse this 2G user and insert 3G network after, feedback position upgrades accepts (Location Update Accept) message or the VLR that refusal (Location UpdateReject) message is given this user visiting is upgraded in the position.

Step S10, VLR and then feed back corresponding Location Update Accept message or LocationUpdate Reject message is given the MSC of this user roaming place;

Step S11, MSC again so that the wireless access network UTRAN by 3G network feed back corresponding Location Update Accept message or Location Update Reject message to the mobile subscriber, whether allow its access network to inform this mobile subscriber.

The Mobile Subscriber International ISDN Number of jack per line section is that example describes the method principle that network control user of the present invention inserts to distinguish 2G user and 3G subscription at distribute not respectively for 2G user and 3G subscription more below.With reference to Fig. 4, this figure is in the method that inserts of network control user of the present invention, with the Mobile Subscriber International ISDN Number of the jack per line section not access control process schematic diagram as 2G user and 3G subscription identification information; The concrete processing procedure that its 3G network control 2G user inserts is as follows:

Step S20, the mobile subscriber sends location update request message (MM Location Updating Request) by the wireless access network UTRAN of 3G network to the MSC of roaming place, wherein carry this user's who preserves in its user's SIM card or the usim card IMSI number or the temporarily moved subscriber identifier (TMSI that previous access network distributes in the MM LocationUpdating Request message, Temporary MobileSubscriber Identity), and the location area information at this current place of user, wherein location area information comprises the LAI (Location Area Id, i.e. lane place ID) and the Cell ID (sub-district ID) at this present place of user.

Step S21, the MSC response MM Location Updating Request message of user roaming place sends the VLR that the location area updating message (MAP Update LocationArea) that comprises this user IMSI number is given user visiting then.

Step S22, the VLR of user visiting response MAP Update Location Area message is sending the location update message Location Update Location that comprises this user IMSI number HLR under this user then.

Step S23, HLR detects the IMSI number that carries in the Location Update Location message, carry out the legitimacy authentication operations with identity to this user, if this IMSI number has record in the database of HLR, illustrate that then this user is a validated user, continue subsequent treatment, HLR is saved in user position information in the database simultaneously; Otherwise illustrate that this user is illegal user, HLR will not allow this user access network, and directly execution in step S28 sends refuse information.HLR also can be according to this user's IMSI Query Database simultaneously, find the Mobile Subscriber International ISDN Number that should the user and all kinds of business information of this user applies, will be encapsulated in the insertion subscriber data message (MAP Insert Subscriber Data) that will send to VLR the Mobile Subscriber International ISDN Number that should the user and all kinds of business information of this user applies then.

Step S24, HLR send to MAP Insert Subscriber Data message the VLR of user visiting.

Step S25, the VLR of user visiting judges that according to this user's who comprises in the MAP Insert Subscriber Data message Mobile Subscriber International ISDN Number this access user is 2G user or 3G subscription; Because the IMSI shuffling of 2G user and 3G subscription, but corresponding different MSISDN section, disposed which MSISDN section and belong to 2G user in VLR, which MSISDN section belongs to 3G subscription, so VLR just can judge that this user is 2G user or 3G subscription according to user's Mobile Subscriber International ISDN Number.Drawing this user as judgement is that 2G user and 3G network are set to refuse 2G user's access, then goes to execution in step S29 feedback refuse information; As being that 2G user and 3G network are set to allow 2G user to insert, then continue execution in step S26.

Step S26, extract self unsupported business information in all kinds of business information that the VLR of user visiting comprises simultaneously in MAP Insert Subscriber Data message, and self unsupported business information that will extract is encapsulated in the insertion user data response message (MAP InsertSubscriber Data Ack) that will feed back to HLR.

Step S27, the VLR of user visiting give MAP Insert Subscriber Data Ack message feedback the HLR of this user attaching.

Step S28, HLR is according to the unsupported business information of VLR that comprises in the MAP Insert Subscriber Data Ack message, draw VLR and do not support which business, and then whether unsupported business information decision is wanted so limited this 2G user and insert 3G network according to VLR.And then HLR determine allow or refuse this 2G user and insert 3G network after, feedback position upgrades accepts (Location UpdateAccept) message or the VLR that refusal (Location Update Reject) message is given this user visiting is upgraded in the position.

Step S29, VLR and then feed back corresponding Location Update Accept message or LocationUpdate Reject message is given the MSC of this user roaming place.

Step S30, MSC again so that the wireless access network UTRAN by 3G network feed back corresponding Location Update Accept message or Location Update Reject message to the mobile subscriber, whether allow its access network to inform this mobile subscriber.

Last again at being that example describes the method principle that network control user of the present invention inserts to distinguish 2G user and 3G subscription for 2G user distributes different user type identification codes respectively with 3G subscription.With reference to Fig. 5, this figure is in the method for network control user access of the present invention, with the access control process schematic diagram of different user type identification codes as 2G user and 3G subscription identification information; The concrete processing procedure that its 3G network control 2G user inserts is as follows:

Step S31, the mobile subscriber sends location update request message (MM Location Updating Request) by the wireless access network UTRAN of 3G network to the MSC of roaming place, wherein carry this user's who preserves in its user's SIM card or the usim card IMSI number or the temporarily moved subscriber identifier (TMSI that previous access network distributes in the MM LocationUpdating Request message, Temporary MobileSubscriber Identity), and the location area information at this current place of user, wherein location area information comprises the LAI (Location Area Id, i.e. lane place ID) and the Cell ID (sub-district ID) at this present place of user.

Step S32, the MSC of user roaming place send the VLR that the location area updating message (MAP Update Location Area) that comprises this user IMSI number is given user visiting then.

Step S33, the VLR of user visiting send the location update message Location Update Location that comprises this user IMSI number then and arrive the affiliated HLR of this user.

Step S34, HLR detects the IMSI number that carries in the Location Update Location message, carry out the legitimacy authentication operations with identity to this user, if this IMSI number has record in the database of HLR, illustrate that then this user is a validated user, continue subsequent treatment, HLR is saved in user position information in the database simultaneously; Otherwise illustrate that this user is illegal user, HLR will not allow this user access network, and directly execution in step S39 sends refuse information.HLR also can be according to this user's IMSI Query Database simultaneously, find the user type identification code that should the user and all kinds of business information of this user applies, will be encapsulated in the insertion subscriber data message (MAP Insert Subscriber Data) that will send to VLR the user type identification code that should the user and all kinds of business information of this user applies then.

Because not only preserve all kinds of business information among the HLR under this user to IMSI number, Mobile Subscriber International ISDN Number and this user applies that should the user, also preserve one simultaneously to user type identification code that should the user, being used to identify this user is 2G user or 3G subscription.When the user opens an account in the business hall, the instruction of opening an account is sent out to HLR in the business hall, wherein just comprise the user type identification code that comprises this user in this instruction of opening an account,, defaultly think that this user is 2G user if do not carry this user type identification code parameter in the instruction of opening an account of business hall.HLR receives to open an account to instruct and handles, if handle successfully, just will be kept in its data storehouse with these user-dependent all information, comprising this user type identification code.The user can also and then revise the user type identification code of its 2G user or 3G subscription by the business hall.

Step S35, HLR send to MAP Insert Subscriber Data message the VLR of user visiting.

Step S36, the VLR of user visiting judges that according to this user's who comprises in the MAP Insert Subscriber Data message user type identification code this access user is 2G user or 3G subscription; Drawing this user as judgement is that 2G user and 3G network are set to refuse 2G user's access, then goes to execution in step S40 feedback refuse information; As being that 2G user and 3G network are set to allow 2G user to insert, then continue execution in step S37.

Wherein subsequent step S37 repeats no more to the processing procedure of step S30 with step S26 among Fig. 4 here to the processing procedure of step S41.

Above-mentioned just by the function of exchange entity (MSC and VLR) in 3G network lateral circuit territory and the HLR under the user location update request message that the user sends is treated to example, the method principle that network control user of the present invention is inserted elaborates.And come user's location update request message is handled with the concrete processing procedure that realizes the method that network control user of the present invention inserts similar to the above process by the HLR under the function of exchange entity (SGSN) of 3G network side packet domain and the user, no longer too much give unnecessary details here.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
