Description

A method for realizing one machine with multiple numbers in the global mobile communication system

technical field

The invention relates to a method for distributing mobile subscriber numbers in the Global System for Mobile Communications (GSM), in particular to a method for enabling one mobile terminal or mobile phone to have multiple mobile subscriber ISDN numbers.

Background technique

GSM digital cellular technology has won increasingly widespread recognition around the world, becoming a mobile communication system with the largest number of users and the largest coverage area. With the increasingly fierce competition in the communication market, GSM operators urgently need to strengthen their own market competitiveness by providing various types of services and increasing network coverage. Because some users may need to use different phone numbers according to different purposes, it is a very popular business to have multiple phone numbers for the same GSM mobile phone.

In GSM call service and other services, International Mobile Subscriber Identity (IMSI) and Mobile Subscriber ISDN (MSISDN) are used to characterize the identity information of each mobile user or mobile station, which are stored in their respective home location registers as user information (HLR) and have a one-to-one correspondence. In the GSM system, when a mobile station or a GSM mobile phone makes a call as a calling party, it first sends a request for access information to the system. After receiving the request information, the system confirms the identity of the mobile station and decides whether to allow access. The mobile switching center + visitor location register (VMSC) to which the mobile station belongs sends confirmation access request information to the mobile station, and the mobile station initiates a call. When the mobile station is used as the called party, the calling party sends the MSISDN of the called party to The HLR to which the called party belongs converts the MSISDN into an IMSI, finds out the service area to which the called party belongs according to the IMSI, and sends the IMSI to the VLR in the area to request allocation of a roaming number (MSRN), and the VLR to which the called mobile station belongs will allocate The MSRN of the caller is sent back to the HLR, and then the HLR sends it to the GMSC or VMSC to which the calling party belongs, so that the GMSC or VMSC of the calling party can be routed to the VMSC of the called party.

In order to make a GSM mobile phone have multiple MSISDN numbers, the method of dual SIM cards is generally adopted at present, that is, two subscriber identification cards (SIM cards) are installed in a GSM mobile phone, and each SIM card has different MSISDNs, and Each MSISDN corresponds to a different IMSI. It is worth pointing out that the same user has two MSISDNs and two corresponding IMSIs in the HLR at this time. After the mobile phone is turned on, both MSISDNs are activated and in standby mode. When the user dials as a calling party, he can choose one of the MSISDNs as the calling party number, and when called, both MSISDNs can be used as the receiving party's number.

But there is obvious shortcoming in the method for above-mentioned realization GSM mobile phone multi-number. Specifically, users must purchase mobile phones that support dual SIM cards to enjoy this service, and the selection of mobile phone purchases is relatively small.

Contents of the invention

The purpose of the present invention is to provide a kind of method that realizes one machine with multiple numbers in Global System for Mobile Communications (GSM), it does not need mobile users to use dual SIM card mobile phones, and does not have special requirements to network equipment such as present HLR, MSC.

According to the method for realizing one machine with multiple numbers in the global system for mobile communication GSM of the present invention, wherein, the GSM mobile communication network and the intelligent network are interconnected according to the customized application CAMEL protocol of mobile network enhanced logic, and each mobile user can be allocated An International Mobile Subscriber Identity (IMSI) and a group of mobile subscriber ISDN MSISDN corresponding to it become CAMEL smart users. The MSISDN belonging to the same group correspond to the same subscription data information in the home location register HLR of the GSM mobile communication network. IMSI and The corresponding relationship between MSISDN is stored in the same service control point SCP of the intelligent network. When the mobile user starts up, he only registers in the corresponding HLR with a number in the MSISDN group assigned by him. When starting a mobile communication service , the system performs the following steps:

(1) The mobile service switching point MSSP of the GSM mobile communication network determines whether the calling party or the called party is a CAMEL smart user according to the subscription data information provided by the HLR;

(2) If it is determined that the calling party or the called party is a CAMEL smart user, the MSSP will hand over the service to the SCP for processing; and

(3) The SCP converts the MSISDNs of the calling party and the called party according to the registration status of the MSISDNs of the calling party and the called party in the HLR, and instructs the MSSP to convert the MSISDNs of the calling party and the called party Complete follow-up business processing as the calling party and called party numbers.

As can be seen from the above, the method for realizing one machine with multiple numbers utilizes the intelligent network interconnected with the GSM mobile network in the GSM of the present invention, and regards the one machine with multiple numbers service as an independent intelligent service outside the mobile exchange to realize, to the present There are no special requirements for network equipment such as HLR and MSC.

Detailed ways

In the implementation method of the global system for mobile communication (GSM) one machine with multiple numbers according to the present invention, the GSM mobile communication network and the intelligent network are interconnected according to the customized application of mobile network enhanced logic (CAMEL) protocol. The CAMEL protocol is the mainstream solution for the interconnection between GSM mobile networks and intelligent networks. By introducing CAMEL services into GSM, operators can establish an intelligent network platform to define and implement new value-added services. Under the CAMEL protocol, the Mobile Switching Center (MSC), Gateway Mobile Switching Center (GMSC), Mobile Switching Center+Visitor Location Register (VMSC) and Short Message Mobile Switching Center (SMSC) in the mobile communication network have mobile service switching capabilities. The function can be classified as a mobile service switching point (MSSP), while other entities in the mobile network remain unchanged. For each one-machine-multiple-number subscriber, they are assigned an International Mobile Subscriber Identity (IMSI) and a corresponding group of Mobile Subscriber ISDN (MSISDN), and the MSISDN belonging to the same group is in the Home Location Register (HLR) Corresponding to the same subscription data information, the corresponding relationship between the IMSI and the MSISDN is stored in the service control point (SCP) of the intelligent network. Subscription data information includes, but is not limited to, the user's relevant number (IMSI and MSISDN), user category, and intelligent network service supplementary information. It is worth pointing out that the subscription data information of each MSISDN in the same group does not have to be stored in the same HLR, but can be stored in different HLRs. But the corresponding relationship between IMSI and MSISDN can only be stored in the same Service Control Point (SCP) of the intelligent network.

Under the above-mentioned network structure and mobile user number allocation and registration methods, when starting a service, if the MSSP determines that the calling party or the called party is an ordinary user instead of a CAMEL smart user according to the subscription data information, then in GSM mobile In the communication network, the business processing is completed according to the business logic that one IMSI corresponds to one MSISDN, which will not be repeated here.

If it is determined that the calling party or the called party is a CAMEL smart user, the MSSP will hand over the service to the service control point (SCP) for corresponding service logic processing. After the SCP makes a corresponding conversion to the MSISDN of the calling party or the called party, it instructs the MSSP to use the converted MSISDN as the calling party number or the called party number to complete subsequent service processing. Specifically, if the SCP determines that the calling party intends to use the MSISDN registered in the HLR as the calling party number or determines that the called party number is an MSISDN registered in the HLR, it instructs the MSSP to use the MSISDN as the calling party number Or the called party number completes the follow-up service processing. If the SCP determines that the calling party intends to use the MSISDN that is not registered in the HLR as the calling party number, it searches for the MSISDN that is to be used as the calling party number according to the corresponding relationship between the IMSI and the MSISDN and Instruct the MSSP to use the searched MSISDN as the calling party number to complete subsequent business processing. If the SCP determines that the called party number is an MSISDN that has not been registered in the HLR, it will search for registrations in the same group in the HLR according to the correspondence between IMSI and MSISDN MSISDN and instructs the MSSP to use the registered MSISDN as the called party number to complete subsequent service processing. The above-mentioned follow-up service processing completed by the MSSP includes switching service processing without the participation of the service control entity in the intelligent network.

The calling party can add a prefix number before the called party number to indicate that the calling party intends to use the MSISDN that is not registered in the HLR as the calling party number, and each prefix number is the same as that of the MSISDN that is not registered in the HLR in the same group. There is one-to-one correspondence between MSISDNs, so the SCP can determine the MSISDN that the calling party intends to enable that is not registered in the HLR according to the prefix number.

As can be seen from the above, in the method of the present invention, each one-machine-multiple-number user is regarded as an intelligent network one-machine multiple-number service user rather than a plurality of mobile network common service users with different MSISDNs, and each one-machine multiple-number service user The service that the machine multi-number user participates in as the calling party or the called party is regarded as an intelligent service and is processed with corresponding business logic.

A specific example of the method according to the invention is described below with the aid of FIGS. 1 to 7 . For the sake of simplicity, assume that a mobile user is assigned an IMSI and two corresponding MSISDNs, and the two MSISDNs are respectively recorded as DN1 and DN2, where DN1 is the home location register HLR1 that stores its subscription information data when the user is turned on. The registered number is called the real number here, and the subscription data of DN2 is the same as that of DN1 and is stored in the home location register HLR2, which is called a virtual number here, and HLR1 and HLR2 may or may not be a home location register. DN1 and DN2 are registered in the SCP as one-device-multiple-number smart users, and the corresponding relationship between DN1 and DN2 and the IMSI is also stored in the SCP. When the calling party wants to use DN2 as the calling party number, add a prefix number before the called party number, for example, 17999.

A. The calling party initiates a call with DN1 as the calling party number

After the user turns on the phone, he registers on HLR1 with DN1, and then HLR1 sends the mobile originating CAMEL service information (O-CSI) to the VMSC to which it belongs. When the user uses DN1 as the calling party number to make a call, that is, directly dials the called number, as shown in Figure 1, the VMSC triggers the intelligent service at the DP2 detection point and sends an InitialDP message to the SCP, which contains the calling party Parameters CallingPartyNumber[DN1] and CalledPartyBCDNumber[RealcalledNumber] for real number and dialed number. The SCP calls the business logic according to the business key, sends a RequestReportBCSMEvent (RRBE) message, and configures relevant EDP detection points for the VMSC. If charging needs to be performed by the SCP, the SCP sends an ApplyCharging (AC) operation to the VMSC to instruct the VMSC to report charging information. The SCP also issues a Continue operation to the VMSC to instruct the VMSC to use the DN1 and the dialed number as the calling party and called party numbers to continue to complete subsequent service processing.

B. The calling party initiates a call with DN2 as the calling party number

After the user turns on the phone, he still registers on HLR1 with DN1, and then HLR1 sends the mobile originating CAMEL service information (O-CSI) to the VMSC to which it belongs. When the user wants to use DN2 as the calling party number, use the special prefix + called number to dial, that is, the dialed number is 17999 + called number. As shown in Figure 2, at this time, the VMSC triggers the intelligent service at the DP2 detection point, and sends an InitialDP message to the SCP, which contains the parameters CallingPartyNumber[DN1] and CalledPartyBCDNumber[Prefix+RealcalledNumber] indicating the real number of the calling party and the dialed number . The SCP invokes the service logic according to the service key, sends the RRBE message to the VMSC, and configures relevant EDP detection points for the VMSC. Similarly, if the SCP needs to perform charging, the SCP sends the AC operation to the VMSC, instructing the VMSC to report the charging information. Because the dialed number contains a special prefix, the SCP finds the virtual number DN2 according to the configured special prefix and virtual number correspondence table, and sends a Connect operation to the VMSC. In the Connect operation, the parameter GenricNumber is changed to the DN2 number, and the special prefix is removed from the DestRoutingAddress Instead, change to the actual called party number. After receiving the Connect operation, the VMSC continues to complete subsequent service processing according to the new calling and called numbers.

C. Call processing flow when the called party uses DN1 as the called party number

As shown in Figure 3, when GMSC (if the calling party is a fixed subscriber) or MSC (if the calling party is also a mobile subscriber) receives a call with the called party number being DN1, it sends an SRI message to HLR1 to search for the subscription data of DN1 Information, HLR1 judges that the mobile subscriber subscribes to the smart service, so the SRI ack message that will include the mobile terminal CAMEL service information (T-CSI) is sent back to the (G)MSC. (G) The MSC triggers the intelligent service at the DP2 detection point, and sends an InitialDP message to the SCP, which includes a parameter CalledPartyBCDNumber[DN1] indicating the dialed number. The SCP calls the service logic according to the service key, sends the RRBE message to the (G)MSC, and configures the relevant EDP detection point to the (G)MSC. If charging needs to be performed by the SCP, the SCP issues an AC operation to the (G)MSC, instructing the (G)MSC to report charging information. The SCP also sends a Continue operation to the (G)MSC to instruct it to use DN1 as the called party number to continue to complete subsequent service processing. (G) The MSC sends the SRI message containing the T-CSI suppression information to the HLR1 to which the DN1 belongs according to the called party number DN1. After receiving the SRI message, HLR1 sends a PRN message to the VMSC to which DN1 belongs to request a roaming number. The VMSC returns the PRN ack message containing the called party's roaming number to the HLR1 according to the PRN message. After HLR1 receives the PRN ack message, it includes the roaming number of the called party in the SRI ack message and sends it back to the (G)MSC, so that the (G)MSC to which the calling party belongs and the VMSC to which the called party belongs can be established. Voice routing.

D. Call processing flow when the called party uses DN2 as the called party number

As shown in Figure 4, when GMSC (if the calling party is a fixed subscriber) or MSC (if the calling party is also a mobile subscriber) receives a call with the called party number being DN2, it sends an SRI message to HLR2 to search for the subscription data of DN2 Information, HLR2 judges that the mobile subscriber subscribes to the smart service, so the SRI ack message that will include the mobile terminal CAMEL service information (T-CSI) is sent back to the (G)MSC. (G) The MSC triggers the intelligent service at the detection point of DP2, and sends an InitialDP message to the SCP, which contains the parameter CallingPartyNumber[DN2] indicating the dialed number. The SCP calls the service logic according to the service key, sends the RRBE message to the (G)MSC, and configures the relevant EDP detection point to the (G)MSC. If charging needs to be performed by the SCP, the SCP issues an AC operation to the (G)MSC, instructing the (G)MSC to report charging information. Since the dialed number contains a special prefix, the SCP finds the virtual number DN1 according to the configured special prefix and virtual number correspondence table, and sends a Connect operation to the (G)MSC. In the Connect operation, the parameter DestRoutingAddress is changed to DN1. (G) The MSC sends the SRI message containing the T-CSI suppression information to the HLR1 to which the DN1 belongs according to the called party number DN1. After receiving the SRI message, HLR1 sends a PRN message to the VMSC to which DN1 belongs to request a roaming number. The VMSC returns the PRN ack message containing the called party's roaming number to the HLR1 according to the PRN message. After HLR1 receives the PRN ack message, it will include the called party's roaming number in the SRI ack message and send it back to the (G)MSC, so that the (G)MSC to which the calling party belongs and the VMSC to which the called party belongs can be established. Voice routing.

E. The calling party uses DN1 as the calling party number to send a short message processing flow

After the user turns on the phone, he registers on HLR1 with DN1, and then HLR1 sends the mobile originating/terminal short message CAMEL service information (O/T-SMS-CSI) to the VMSC to which it belongs. When the user uses DN1 as the calling party number to send a short message to the called party, as shown in Figure 5, the VMSC triggers the intelligent service at the DPSMS_Collected_Info detection point and sends the InitialDP SMS message to the SCP. The SCP calls the business logic according to the business key, sends a RequestReportSMSEvent (RRSE) message, and configures relevant EDP detection points for the VMSC. The SCP also issues a Continue SMS operation to the VMSC to instruct the VMSC to use the DN1 and the input called party number as the calling party and the called party number to continue to complete subsequent business processing.

F. The processing flow of the calling party sending a short message with DN2 as the calling party number

After the user turns on the phone, he still registers on HLR1 with DN1, and then HLR1 sends the mobile originating/terminal short message CAMEL service information (O/T-SMS-CSI) to the VMSC to which he belongs. When the user wants to use DN2 as the calling party number, enter the special prefix + called number as the called party number, for example, 17999 + called number. As shown in Figure 6, at this time, the VMSC triggers the intelligent service at the DP SMS_Collected_Info detection point, and sends the InitialDP SMS message to the SCP, which contains the parameter CPN[DN1] indicating the real number of the calling party and the called party number with a special prefix and DSN[Prefix+CalledNumber]. The SCP invokes the service logic according to the service key, sends the RRSE message to the VMSC, and configures relevant EDP detection points for the VMSC. Because the dialed number contains a special prefix, the SCP finds the virtual number DN2 according to the configured special prefix and virtual number correspondence table, and sends the Connect SMS operation to the VMSC. In the Connect operation, the parameter CPN is changed to the DN2 number, and the DSN removes the special number. prefix instead of the actual called party number. After receiving the Connect operation, the VMSC continues to complete subsequent service processing according to the new calling and called numbers.

G. The processing flow of the called party sending a short message with DN1 as the calling party number

The called user still registers on HLR1 with DN1 after turning on the phone, and then HLR1 sends the mobile originating/terminal short message CAMEL service information (O/T-SMS-CSI) to the VMSC to which it belongs. As shown in Figure 7, when the short message mobile switching center (SMSC) to which the calling party belongs receives the short message that the called party number is DN1, it sends an SRI message suppressing CSI to the HLR1 to which the calling party belongs, and HLR1 sends The SRI ack message containing the mobile subscriber's roaming number (MSRN) is sent back to the SMSC. After receiving the SRI ack message, the SMSC provides the short message SMS to the VMSC to which the called party belongs, and the VMSC triggers an intelligent service at the DPSMS_Collected_Info detection point, and sends an InitialDP SMS message to the SCP, which contains the called party number DN1. The SCP calls the service logic according to the service key, sends the RRSE message to the VMSC, and configures the relevant EDP detection points to the VMSC. The SCP also issues a ContinueSMS operation to the VMSC to instruct it to use DN1 as the called party number to continue to complete subsequent service processing.

H. Other business

(1) For calling number display, when the calling party uses DN2 as the calling number, the MSC to which the called party belongs shall use the calling party number DN2 included in the Connect operation issued by the SCP as the calling number.

(2) For the SCP-based forwarding services CFU, CFNA, CFB, and CFD, when DN2 is used as the called party number, although the called party number has been converted by the SCP to DN1, but because the SCP is still triggered after the forwarding, the SCP stores the information of converting DN2 to DN1, so that the forwarding service of the virtual number based on the SCP can still be realized.

(3) For supplementary services such as CW, CC, 3WC, etc., they are similar to the process of calling and calling, so these supplementary services can also be realized under the virtual number.
