Description

Method and system for access control of intelligent services

technical field

The invention belongs to the field of intelligent network communication, and in particular relates to a method and a system for controlling the access of intelligent services.

Background technique

With the continuous upgrading of wireless networks, it is the general trend to provide rich data services. Telecom operators only provide real-time traffic control for voice, which cannot meet the needs of customers for rich multimedia services. However, real-time billing for the integration of multiple services is more complicated than traditional voice billing. In order to better provide real-time billing and traffic control of multimedia services, the efficiency of the service control system is required to be higher.

According to the intelligent network structure defined by 3GPP (Third Generation Partnership Projects, third-generation partnership organization plan), as shown in Figure 1, the user data information stored in HLR (Home Location Register, home location register) OCSI (Originating CAMEL Subscription Information, mobile Intelligent service originating contract information), through the "insert user data" operation into the MSC (Mobile service Switching Center, mobile service switching center). When MS (MobileStation, mobile station) initiates a call, gsmSSF (Global System Mobile Service SwitchFunction, global system mobile communication system service switching function) requests gsmSCF (gsm ServiceControl Function, gsm service control function) according to OCSI, and accepts the control of gsmSCF or surveillance. The CAP (CAMEL Application Part, mobile intelligent service application part) protocol is adopted between gsmSSF and gsmSCF, that is, gsmSCF controls user calls on gsmSSF through the CAP protocol. In the intelligent network architecture, SSP (Service Switching Point, service switching point) includes the SSF function, and SCP (Service Control Point, service control point) includes the SCF function.

The real-time access control flow of a call on the intelligent network is shown in Figure 2, and the details are as follows:

1. SSP sends an IDP (Initial Detection Point, start detection point) message to SCP to start a dialogue with SCP;

2. After the SCP queries the account balance, budget duration and other resource reservation operations according to the IDP message, it sends a RRBE (Request report Basic Call State Model event, request to report BCSM event) message to the SSP;

3. SCP sends AC (Apply Charging) to SSP;

4. SCP sends CON (Continue, continue) to SSP;

5. SSP reports ACR (Apply Charging Report) to SCP, notifies SCP of the charging result, SCP deducts the fee from the user account, and re-estimates the call duration according to the remaining balance;

6. SCP sends AC to SSP;

Repeat steps 5 and 6 above until either the calling party or the called party hangs up, and continue to perform the following steps:

7. SSP reports ERB (Event Report BCSM, BCSM event report) to SCP;

8. SCP issues RC (Release Call, release call) to SSP to release the resources occupied by this call.

It can be seen from the above steps that after receiving the IDP message, the SCP needs to perform resource reservation operations such as querying the account balance and budget duration for this call, and then instructs the MSC/SSP to connect the call. If the MSC/SSP does not connect to the call subsequently, it is not necessary to reserve resources for this call on the SCP. The connection rate of intelligent calls is generally 50%, that is, even if 50% of false service calls are not connected, the system needs to perform resource reservation operations, which reduces the service access performance of the system.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention classifies users for service access according to user attribute information. When a user initiates a service access request, corresponding service access control is performed according to the service access classification to which the user belongs, and no resources are used for service access requests of some users. Reserve and directly issue access resources, thereby improving the performance of system service access as a whole.

As an embodiment of the present invention, according to different user attribute information, users are divided into two categories: those who need to reserve resources and those who do not need to reserve resources. When a user who needs to reserve resources initiates a service access request, the system It performs resource reservation operation in advance. When a user who does not need to make resource reservation initiates a service access request, the system does not perform resource reservation operation in advance, and directly issues access resources to complete the continuation of the service request.

Whether a user needs to reserve resources is flexibly set by the operator according to user attribute information. Specifically, it can be based on any one or any combination of the user's access number type, account attribute, customer category, service type, tariff attribute, or call attribute. combination of species, in which:

The access number type is, for example, an MSISDN (Mobile Station international ISDN number, mobile station international ISDN) number or a PSTN (Public Switching Telephone Network, public switched telephone network) number.

The account attribute is the entity that the operator conducts telecommunications business revenue and expenditure to the customer. It is the serial number of the user account. The mobile operator collects the business expenses generated by this number into this account, and charges the user through this account.

The customer category is, for example, an individual user or an organizational user.

The service type is, for example, various preferential services promoted by the operator to the society, such as the M-Zone youth package, etc., or non-preferential regular services.

The tariff attribute is the tariff policy formulated by the operator for each telecommunication service. For example, the basic call fee of China Express is 0.6 yuan per minute.

The call attribute is the attribute of each call initiated by the user. For example, when the user initiates a call from the roaming city of Beijing, Beijing is the call attribute of the user. When an international call is initiated, the call attribute is an international call, etc.

As an embodiment of the present invention, users whose access number type is MSISDN, users with relatively large account balances, users in units of customer categories, users of preferential services provided by operators, roaming users or international phone users, etc. can be used as For non-reserved users, when these users initiate a call, the system can directly issue access resources for call connection without pre-reserving resources. Of course, these users can also be used as users who need to reserve resources, which are set flexibly by operators according to service requirements.

In one embodiment of the present invention, the system can determine the corresponding user data flag bit according to the service access classification of the user, and perform subsequent connection operations according to the value of the user data flag bit when receiving a call from the user. For example, when the user's access number type is an MSISDN number, set the user data mark position to 1, and if it is a PSTN number, set the user data mark position to 0.

Fig. 3 has shown the system structure applicable to the present invention, service provision equipment 100 is various core network business service equipment, can be 2G MSC/SSP, 3G MSC Server/SSP, SGSN (Serving GPRSSupport Node, GPRS service support node)/ SSP or IMS (Internet Multimedia Subsystem, Internet Multimedia Subnet)/SSF, etc., receives the user's service access request, and performs a connection operation on the user's service access request according to the access resources issued by the control device 200. The control device 200 may be a real-time control device such as SCP or OCS (Online Charging System, Online Charging System), which stores user attribute information, service access classifications corresponding to the corresponding user attribute information, and service access classifications corresponding to the service access classifications. User data flag. When a user initiates a service access request, the control device 200 obtains the corresponding user data flag bit according to the user service access request, and performs corresponding resource reservation control operations on the service access request according to the user data flag bit, and provides the service providing device 100 delivers access resources.

Fig. 4 shows the implementation flow of the service access control for the user's service access request provided by the present invention, which is described in detail as follows:

In step S401, the service providing device 100 receives a user's service access request;

In step S402, the control device 200 determines the user data flag of the service access category corresponding to the user according to the user information carried in the user's service access request, such as the user's calling number, called number or user name, when the user When the value of the data flag is 0, execute step S403, and when it is 1, execute step S404;

In the present invention, when the user's access service classification is judged and determined according to the user's access number type, account attribute, customer category, service type, tariff attribute and other attribute information, the control device 200 determines the user's service access request. The corresponding user data flag can be determined by judging the user information. When the user's access service classification is judged and determined according to the call attribute, when the user initiates a service access request, the service providing device 100 reports a session start request to the control device 200, and the control device 200 reports the session start request according to the user's current service access request. The call attribute of the call determines the corresponding user data flag.

In step S403, the control device 200 executes step S404 after performing resource reservation operations such as querying user account balance and budget duration;

In step S404, the control device 200 issues access resources to the service providing device 100;

In step S405 , the service providing device 100 performs a call connection to the service access request of the user according to the access resource issued by the control device 200 .

Figure 5 shows the signaling flow of the real-time service control of a session access service, which is described in detail as follows:

1. When the user has a session access request, the service providing device 100 sends a session start request to the control device 200;

2. The control device 200 responds to the session start request of the service providing device 100, and judges the user data flag bit. If the user data flag bit is 1, the control device 200 directly sends access resources to the service providing device 100. If the user data The flag bit is 0, and the control device 200 issues corresponding access resources to the service providing device 100 after querying the user account balance, budget duration and other resource reservation operations;

3. The service providing device 100 connects according to the issued access resources, and monitors the call process according to the issued access resources, and initiates an intermediate report request to the control device 200 when the resources are exhausted;

4. The control device 200 responds to the intermediate report request, charges according to the monitored resources, deducts the fee from the user's account, makes a budget according to the remaining account balance, and issues a corresponding amount of resources to the service provider device according to the budget result 100;

Repeat steps 3 and 4 above until the user actively releases the session, and perform the following steps:

5. The service providing device 100 initiates an end notification to the control device 200;

6. The control device 200 charges according to the resources actually consumed by the user, deducts the fee from the user's account, and ends the call.

FIG. 6 shows the structure of a service access control system 600 provided by the present invention. The service access control system 600 may be a built-in software system or module in the control device 200 such as SCP or OCS.

The user information database 601 stores user attribute information, service access categories corresponding to the corresponding user attribute information, and user data flags corresponding to the service access categories. Specifically, the user's calling number, called number, or user Name and other information as the index.

When a user initiates a service access request, the service connection control unit 602 queries the user information database 601 according to the user information carried in the user service access request, such as the user's calling number, called number or user name, to determine the The above-mentioned service access classification and corresponding user data flag bits, and perform corresponding service connection control according to the user data flag bits. When the value of the user data flag is 1, the access resource is directly delivered to the service providing device 100; The device 100 issues access resources.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
