Description

Realization method of general personal communication service

technical field

The invention relates to the field of mobile intelligent network, in particular to a method for realizing general personal communication service in the mobile intelligent network system.

Background technique

Universal Personal Telecommunications (UPT, Universal Personal Telecommunication) service, commonly known as "one number" service, is a new value-added service currently running in the fixed communication network system. UPT service means that fixed communication network users apply for a unique personal universal number (700+N1N2+user number is generally used now, where 700+N1N2 is the access code of UPT service, and N1N2 identifies the service corresponding to each personal universal number Control point (SCP, Service Control Point), when a user who has applied for the UPT service is called, the fixed communication network will transfer the call to multiple fixed service stations designated by the user in advance according to the connection attribute of the UPT service applied by the user. Phone, mobile phone or other communication terminals, so that the connection between the two parties will not be affected by the geographical location.

Referring to FIG. 1 , the specific process of calling a user who has applied for a UPT service in a fixed communication network system is described.

S1: The user first applies for the UPT service, and the operator of the fixed communication network system assigns him a unique personal universal number 700+N1N2+user number, and the calling user dials the personal universal number to call the user who has applied for the UPT service.

S2: The call is first connected to the local exchange (LS, LocalSwitch) of the fixed communication network system, and the LS triggers the UPT service according to the access code 700+N1N2 in the called number, and joins the service switching point before the called number ( SSP, Service Switching Point) routing code prefix, that is, the called number is changed to prefix+700+N1N2+user number (prefix is the SSP routing code), and then the called number is encapsulated into an initialization address message with additional information (IAI , Initial AddressMessage with Information) signaling, the call is connected to the service switching point SSP of the fixed communication network system through the IAI signaling.

S3: The service switching point SSP judges the SCP corresponding to the called number according to the access code 700+N1N2 in the called number prefix+700+N1N2+user number, and then deletes the SSP routing code prefix in the called number, and Trigger an initial detection point (IDP, Initial DP) message, encapsulate the called number 700+N1N2+user number with the SSP routing code prefix deleted in the IDP message, and further connect the call to the corresponding SCP through the IDP message.

S4: The SCP searches the pre-stored connection attribute corresponding to the called number in its own database according to the called number. The connection attribute generally includes the number list TermList of the called multiple connection terminals and the corresponding connection rule Rule. The UPT service in the network system only supports connection rules for sequential calls. Then the SCP sends the connection attribute corresponding to the called number to the SSP through the connection message Connect.

S5: According to the connection attribute corresponding to the called number, the SSP respectively uses the IAI signaling to connect the call to the corresponding called multiple connection terminals through the local exchange LS of each landing office according to the connection rules of sequential calls, until One of the called connected terminal answers.

Through the above process, when a user who has applied for the UPT service in the fixed communication network system is called, it can be realized that the number list TermList of multiple connected terminals of the called party and the corresponding connection rules Rule set in advance, the incoming calls will be called first Connect to each called connecting terminal until one of the called connecting terminals starts to answer.

However, in the prior art, implementing UPT services in a fixed communication network system is only applicable to fixed network users, not to mobile network users. At the same time, fixed network users who apply for the UPT service need to use a new coding method, which wastes the number resources of the fixed communication network operator and is not convenient for the calling and called users to remember. At the same time, the UPT service in the fixed communication network system can only support the connection rules of sequential calls, and the connection rules are very monotonous.

Contents of the invention

The technical problem to be solved by the present invention is to propose a method for realizing general personal communication services, so that general personal communication services can run in the mobile communication network system, and directly use existing mobile numbers as personal universal numbers to save number resources And it is easy for users to remember.

In order to solve the above problems, the present invention proposes a method for realizing a general personal communication service, comprising the following steps:

(11) The calling user initiates a call, and when the mobile switching center judges that the called user has applied for a general personal communication service, the mobile number of the called user is sent to the service control point, and the service control point is requested for the mobile number of the mobile number General personal communication services;

(12) The service control point responds to the request, and connects the mobile number to the independent service switching point through the mobile switching center;

(13) The independent service switching point sends the mobile number to the service control point, so that the service control point starts the general personal communication service of the mobile number;

(14) The service control point starts the general personal communication service of the mobile number according to the received mobile number, and starts the corresponding connection attribute, and sends the connection attribute to the independent service switching point;

(15) The independent service switching point connects with the called multiple terminals according to the connection attribute.

Simultaneously, the present invention also proposes a kind of realization method of general personal communication service, comprises the following steps:

(91) When the calling user initiates a call, and the mobile switching center with the independent service switching point function judges that the called user has applied for a general personal communication service, the mobile number of the called user is sent to the service control point, and the service is sent to the service control point. The control point requests the universal personal communication service of the mobile number

(92) The service control point responds to the request, activates the general personal communication service of the mobile number, and activates the corresponding connection attribute, and sends the connection attribute to the mobile exchange with the independent service exchange point function center;

(93) The mobile switching center with the independent service switching point function connects with multiple called terminals according to the connection attributes.

Beneficial effects of the present invention: Since the realization method of the general personal communication service of the present invention runs on the mobile intelligent network system, it is applicable to all mobile users. At the same time, each mobile user only needs to use its own mobile number as a personal universal number, so mobile operators do not need to redefine a new coding scheme, thereby saving number resources and facilitating the memory of calling and called users. The UPT service connection rule proposed by the invention supports both sequential call and simultaneous call functions, and the connection rule is very flexible.

Detailed ways

The existing Global System for Mobile Communications (GSM, Global System for Mobile Communication) mobile intelligent network adopts the Camel (Customized Applications for Mobile Network Enhanced Logic) protocol, and many mobile exchanges in the GSM mobile intelligent network The center (MSC, Mobile Switching Center) can support the SSP function. At the same time, the GSM mobile intelligent network further contains an independent SSP entity (separated from the MSC), which is used to further process the user's intelligent business. The MSC with the SSP function is as follows Abbreviated as MSC/SSP.

Referring to Fig. 2, it is a schematic diagram of the process of realizing the UPT service according to the sequence call connection rule in the GSM mobile intelligent network system by the implementation method of the general personal communication service of the present invention. First, store the mobile number applying for the UPT service and its corresponding connection attribute in the service control point SCP; at the same time, store the mobile number applying for the UPT service and its corresponding terminal Camel subscription information (hereinafter referred to as the terminal Camel subscription information T-CSI) Stored in the home location register HLR to which the mobile number belongs.

The specific sequence call flow is:

S1: When the calling user calls a mobile user applying for UPT service, directly dial the mobile number (MSISDN, Mobile Station International ISDN Number) of the mobile user, and connect the call to the MSC/SSP in the GSM system;

S2: MSC/SSP searches for the T-CSI information corresponding to the MSISDN in the HLR to which the called party applies for the UPT service, and then the MSC/SSP analyzes the T-CSI information to determine the T-CSI information. The service type corresponding to the CSI information is the UPT service; since the user applies for different services, the data of the Camel subscription information CSI owned by the user is different, so by analyzing the user's Camel subscription information CSI, the service type applied by the user can be determined accordingly;

S3: MSC/SSP sends the MSISDN applying for UPT service to SCP through IDP message, so as to request UPT service of the user from SCP;

S4: After receiving the IDP message, the SCP responds to the UPT service request, adds an independent SSP routing code Prefix to the MSISDN applying for the UPT service, and then sends the Prefix+MSISDN to the MSC/SSP through the connection message Connect;

S5: MSC/SSP sends the Prefix+MSISDN to the independent SSP according to the independent SSP routing code Prefix in the received Prefix+MSISDN number;

S6: The independent SSP deletes the independent SSP routing code Prefix in the received Prefix+MSISDN number, and then sends the MSISDN applying for the UPT service to the SCP through an IDP message, so that the SCP starts the UPT service of the MSISDN;

S7: The SCP starts the UPT service of the MSISDN according to the received IDP message, and finds the connection attribute corresponding to the MSISDN in the pre-stored mapping relationship between the mobile number applying for the UPT service and the corresponding connection attribute according to the received MSISDN, here The connection attributes include the number list TermList of the called multiple connected terminals and the corresponding connected rules Rule. The called multiple connected terminals can be fixed phones, mobile phones, fax machines, pagers, or voice mailboxes. The numbers of each connecting terminal are arranged according to the sequence of answering, that is, the number list TermList of multiple called connecting terminals is formed; the connecting rule Rule here is a sequential call, that is, according to the order of the numbers in the number list TermList of the called connecting terminal Sequential call (here it is assumed that this call is first connected to a fixed phone, but the fixed phone does not answer, then transfer the call to another mobile phone as an example), and then find out the connection attribute corresponding to the MSISDN through The connection message Connect is sent to the independent SSP;

S8: The independent SSP first connects the call to the fixed phone number Term1 according to the first fixed phone number Term1 in the TermList through IAI signaling according to the received number list TermList of the called connection terminal and the corresponding sequential call connection rule Rule The fixed gateway office (GW, Gateway) to which it belongs, connects the call to the corresponding fixed telephone through the fixed gateway office GW;

S9: If the fixed phone is idle, the fixed gateway office GW replies with Address Complete Message (ACM, Address Complete Message) signaling to the independent SSP;

S10: If no one answers the fixed phone call for a long time, the fixed gateway office GW will reply a non-response message to the independent SSP after the specified time, and the independent SSP will connect the call according to the number list TermList of the called terminal The second mobile phone number Term2 of the mobile phone number Term2, the call is connected to the mobile switching center to which the mobile phone number Term2 belongs through IAI signaling, that is, the visiting mobile switching center VMSC;

S11: If the called mobile phone is idle, the VMSC replies the ACM signaling to the independent SSP;

S12: If the called mobile phone starts to answer, the VMSC replies to the answer signal, charging (ANC, Answer Signal, Charge) signaling to the independent SSP;

Then the calling party and the called party can enter the normal conversation process. If the mobile phone is still unable to answer the long-standing call, the independent SSP can continue to call the subsequent called connection terminal according to the follow-up phone number in the TermList until a certain called connection terminal starts to answer.

Referring to Fig. 3, it is a schematic diagram of the process of realizing the UPT service according to the simultaneous call connection rule in the GSM mobile intelligent network system; in the GSM mobile intelligent network communication system, the user who applies for the UPT service can also support the connection rule of the simultaneous call. In the process of realizing the UPT service according to the simultaneous call connection rule, the process from S1 to S7 is the same as the process of S1 to S7 in the process of realizing the UPT service according to the sequential call connection rule, and will not be repeated here. The following mainly describes that when the simultaneous call connection rule is supported, all the preset called multiple connection terminals are called at the same time according to all the phone numbers in the TermList. If one called connection terminal answers first, the other called connection terminals are released. terminal process.

S8a, S8b: The independent SSP simultaneously connects this call through IAI signaling to the fixed gateway office GW to which the fixed telephone number Term1 belongs and the VMSC to which the mobile telephone number Term2 belongs to, respectively through the fixed gateway office GW and VMSC to the fixed gateway office with the number Term1 Phone calls and mobile phones with Term2 numbers;

S9a, S9b: If the fixed phone and the mobile phone are idle at the same time, the fixed gateway office GW and VMSC reply the ACM signaling to the independent SSP at the same time;

S10: If the mobile phone with the number Term2 answers first, the VMSC replies the ANC signaling to the independent SSP;

S11: The independent SSP releases the call to the fixed telephone with the number Term1, and then the caller and the mobile phone with the number Term2 can enter into a normal conversation process.

Through the upgrade of the GSM system, the independent SSP function can be further concentrated in the MSC, so that the GSM mobile intelligent network system does not need to set up an independent SSP entity. In conjunction with Fig. 4 below, the process of realizing the UPT service in accordance with the simultaneous call connection rule in the GSM mobile intelligent network system with the MSC of the independent SSP function is illustrated.

S1: When the calling user calls a mobile user applying for UPT service, directly dial the mobile number MSISDN of the mobile user, and connect the call to the gateway MSC with independent SSP function in the GSM system, hereinafter referred to as MSC/independent SSP;

S2: MSC/independent SSP searches the HLR corresponding to the MSISDN applying for UPT service in the HLR according to the called MSISDN applying for UPT service, and then the MSC/independent SSP performs the T-CSI information Analyze to determine that the service type corresponding to the T-CSI information is a UPT service;

S3: The MSC/independent SSP sends the MSISDN applying for the UPT service to the SCP through an IDP message to request the UPT service of the MSISDN from the SCP;

S4: The SCP starts the UPT service according to the received IDP message, and finds the connection attribute corresponding to the MSISDN in the pre-stored mapping relationship between the mobile number applying for the UPT service and the corresponding connection attribute according to the received MSISDN, and then finds out The connection attribute corresponding to the MSISDN is delivered to the MSC/independent SSP;

S5a, S5b: (G)MSC/independent SSP simultaneously connects this call to the fixed gateway office GW to which the fixed telephone number Term1 belongs and the VMSC to which the mobile telephone number Term2 belongs to through IAI signaling, respectively through the fixed gateway office GW and VMSC The landline phone with the number Term1 and the mobile phone with the number Term2 make a call;

S6a, S6b: If the fixed phone and the mobile phone are idle at the same time, the fixed gateway office GW and the VMSC reply the ACM signaling to the MSC/independent SSP at the same time;

S7: If the fixed telephone with the number Term1 answers first, the fixed gateway office GW replies the ANC signaling to the MSC/independent SSP;

S8: The MSC/independent SSP releases the call to the mobile phone with the number Term2, and then the caller and the fixed phone with the number Term1 can enter into a normal conversation process.

Referring to Fig. 5, it is a schematic diagram of the process of realizing the UPT service according to the sequence call connection rule in the code division multiple access (CDMA, Code Division Multiple Access) mobile intelligent network system. The standard that the existing CDMA mobile intelligent network adopts is Wireless Intelligent Network (WIN, Wireless Intelligent Network). The process of realizing the UPT service by the call connection rule is similar. First, store the mobile number MDN applying for UPT service and its corresponding connection attribute in the service control point SCP; at the same time, store the mobile number MDN applying for UPT service and its corresponding WIN called trigger in the home location to which the mobile number belongs In the register HLR; the difference in processing is as follows:

S2: MSC/SSP searches for the WIN called trigger information corresponding to the MDN in the HLR to which the MDN belongs according to the MDN that the called party has applied for UPT service (the MDN in the CDMA system is the same as the MSISDN in the GSM system), and then the MSC /SSP reports the WIN called trigger information to the SCP, and the SCP analyzes the WIN called trigger to determine that the service type corresponding to the MDN is UPT service; since the user applies for different services, the WIN owned by the user The called trigger data is different, so by analyzing the user's WIN called trigger, the service type applied by the user can be determined accordingly;

S3: The MSC/SSP sends the MDN applying for the UPT service to the SCP through an analysis message (Anlyzd), so as to request the UPT service of the user from the SCP;

S4: After receiving the Anlyzd message, the SCP responds to the UPT service request, adds an independent SSP routing code Prefix for the MDN applying for the UPT service, and then sends the Prefix+MDN to the MSC/SSP through the Anlyzd message;

S6: The independent SSP deletes the independent SSP routing code Prefix in the received Prefix+MDN number, and then sends the MDN applying for the UPT service to the SCP through the Anlyzd message, so that the SCP starts the UPT service of the MDN;

S7: The SCP starts the UPT service of the MDN according to the received Anlyzd message, and finds the connection attribute corresponding to the MDN in the pre-stored mapping relationship between the mobile number applying for the UPT service and its corresponding connection attribute according to the received MDN, and then Send the found connection attribute corresponding to the MDN to the independent SSP through the Anlyzd message;

The rest of the other processes are the same as the corresponding processes of realizing the UPT service according to the sequential call connection rules in the GSM mobile intelligent network system, and will not be repeated here.

Referring to FIG. 6 , it is a schematic diagram of the process of realizing UPT service according to the simultaneous call connection rule in the CDMA mobile intelligent network system. In the CDMA mobile intelligent network system, the process of realizing the UPT service according to the simultaneous call connection rule is similar to that in the GSM mobile intelligent network system. The UPT service information interaction between the SSP and the SCP is transmitted using the Anlyzd message; the UPT service information interaction between the independent SSP and the SCP is also transmitted using the Anlyzd message; the judgment of the UPT service type of the MDN is also performed by searching the HLR to which the MDN belongs. The WIN called trigger information corresponding to the MDN, and then the MSC/SSP reports the WIN called trigger information to the SCP, and the SCP analyzes the WIN called trigger to determine that the service type corresponding to the MDN is a UPT service . Other similar processes will not be repeated here.

The CDMA system can also further centralize the function of the independent SSP into the MSC through upgrading, so that the CDMA mobile intelligent network system does not need to set up an independent SSP entity. Referring to Fig. 7, it is the process of realizing the UPT service according to the simultaneous call connection rule in the GSM mobile intelligent network system with the MSC of the independent SSP function, this process is similar to the process of realizing the UPT service according to the simultaneous call connection rule by upgrading the GSM system, Only the UPT service information interaction between MSC and SCP with independent SSP function is also transmitted by using Anlyzd message. Other similar processes will not be repeated here.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be It is regarded as the protection scope of the present invention.
