Description

Initial filtering rule configuration method

The present invention relates to the field of communications, and in particular, to an initial filter Criteria (iFC) configuration method and an initial filter rule download and processing method using an initial filter rule configuration method. BACKGROUND OF THE INVENTION Currently, the 3rd Generation Partnership Project (3GPP) has introduced the basic principles for IMS networks and services, adopting the idea of separation of control and services, and the IMS control layer does not provide services, but only provides services. Layers are required for triggering, routing, billing, etc., and services are completely provided by the business layer. Service triggering is an important function of the IMS control layer. It is implemented by the Serving Call Session Control Function (S-CSCF) of the IMS control layer. The user's business trigger data is represented by "Service Profiles" and stored as part of the User Profiles data in the Home Subscriber Server (HSS). As shown in FIG. 1 , it is a framework diagram of IMS service triggering, which shows network elements, interfaces, and internal functions of each network element involved in service triggering, and mainly includes a service call session control function (S-CSCF) 102, A Home Subscriber Server (HSS) 104 and an Application Server (AS, Application Server) 106. When the user registers, or when the S-CSCF receives an initial request for a terminating session of an unregistered user, or the S-CSCF receives a server instead of the initial request initiated by the user, the service configuration data is taken from the HSS. Download to the S-CSCF, which includes the initial filtering rules (iFC). The triggering condition of the service is represented by the initial filtering rule, and the user subscription service is different. A user's service configuration will contain multiple initial filtering rules, and these initial filtering rules have their own priorities. The S-CSCF evaluates the registration request and the initial session request according to these initial filtering rules, and sends the requests to the designated application server (AS) according to the evaluation result, and the application servers provide the corresponding services according to the request. In Figure 2, an example of a triggering process for a call request is described. Where the user is configured

1 P17136 The two initial filtering rules X, Y, and S-CSCF match the call request with each rule in priority order, control the call path by triggering, and provide services via the application server. If the service is not activated, that is, the service is authorized by the network provider to the user, but the user is not activated, the application server returns directly without any processing on the incoming call. After receiving the response message, the S-CSCF continues to match the initial filtering rules of the secondary priority and triggers call control to other applications. Obviously, if the service is reserved but not activated, the S-CSCF still has to trigger to the application server according to the initial filtering rules, resulting in unnecessary call control redundancy. The separation of IMS control and service causes the HSS to be unable to sense the service. All the service processing has the application server, which also causes unnecessary call control redundancy. In order to avoid such redundancy, a mechanism is introduced by the application server to inform the HSS which iFCs can be blocked for a particular user or service, so that no download to the S-CSCF is required. This mechanism is currently adopted by the Dynamic Service Activation Info (DSAI) mechanism, that is, the information related to the service activation/deactivation state is carried by the DSAI value, and the AS notifies the HSS through the Sh interface. If the DSAI value is active, it indicates that its associated iFC needs to be downloaded to the S-CSCF by the HSS; if the DSAI value is inactive, it indicates that its associated iFC can be masked and does not need to be downloaded to the S- by the HSS. CSCF. For a better illustration, return to Figure 2. Figure 2 depicts a flow diagram of the service triggering process during call setup. The network elements involved include a Serving Call Session Control Function (S-CSCF) 208, a Home Subscriber Server (HSS) 202, an Application Server 1 (AS1) 204, and an Application Server 2 (AS2) 206, associated with The interface includes a Cx interface between S-CSCF 208 and HSS 202, a Sh interface between AS1 204/AS2 206 and HSS 202, and an ISC interface between AS1 204/AS2 206 and S-CSCF 208. When the network provider deploys the service, such as deploying the call forwarding service, two initial filtering rules X and Y are generated, corresponding to two different pieces, such as busy transfer and no answer transfer, and processed by AS1 204. Busy transfer service, AS2 206 handles non-acknowledgment transfer service. At this time, the HSS 202 is configured with two unique DSAI-tag identifiers, such as DSAI-tag-1 and DSAI-tag-2, associated with the initial filtering rule X and the initial filtering rule Y, respectively. When a user subscribes to a service in an application server in the provider network, that is, the user activates/deactivates the authorized service, the activation/deactivation information of the service is transmitted to the HSS 202 through the DSAI value, and is HSS 202. Determine the associated iFC based on the activation/deactivation status information of the DSAI value

2 P17136 Whether it needs to be downloaded to the S-CSCF 208o The DSAI value is uniquely determined by the DSAI-tag identifier and the specific user or service identifier. For example, if the user goes to live transfer service, the DSAI value uniquely determined by the DSAI-tag-1 identifier and the user identifier is set to deactivate, and the AS1 204 notifies the HSS 202 that the HSS 202 blocks the initial associated with it. Filtering rule X, the initial filter rule X is not downloaded to the S-CSCF 208 by the HSS 202. Figure 3 shows the relationship between DSAI and iFC. The DSAI is associated with at least one iFC. All iFCs associated with the DSAI must be triggered to the same AS, ie only one AS is responsible for updating the DSAI value; the iFC can be associated with one or more DSAIs or not with the DSAL DSAI and The implicit association of iFC is maintained and stored by the HSS. Generally, each end user has one or more service configurations, and each service configuration includes multiple initial filtering rules (iFCs). These initial filtering rules can be regarded as logical expressions, indicating the conditions for service triggering. The destination is triggered and described in text mode, with a large amount of data. Especially when the amount of users is large, it will directly affect the transmission performance of the HSS and S-CSCF service configuration data download interface, and consume the storage space of the HSS and S-CSCF, resulting in a decrease in system capacity or performance. Considering that in actual applications, many users sign up for the same service, for example, the mobile network users basically open supplementary services such as caller ID, call forwarding, etc., that is, these user services use the same or similar initial filtering rules. In addition, some services, such as presenting services, require multiple iFCs to be triggered to multiple application servers in a certain order to complete the service. Therefore, 3GPP introduces the "Shared iFC Sets (SiFC) - hereinafter referred to as the shared iFC set" in the service configuration to optimize the download and storage of service configuration data. The shared iFC set can be shared and used by multiple service configurations. Each shared iFC set is associated with one or more initial filtering rules, and is stored in the local database of the HSS and the S-CSCF respectively, and is maintained and managed by the HSS and the S-CSCF respectively. A unique representation using a shared iFC set identifier. Figure 4 depicts the Advanced Unified Modeling Language (UML) model of the business configuration class, including shared iFC set components. Multiple shared iFC sets can be defined during business deployment, and each shared iFC set is associated with one or more iFCs, labeled with a unique identifier. If both the HSS and the S-CSCF support the function of sharing the iFC set, when the S-CSCF downloads the service configuration data from the HSS, the shared iFC set can be implicitly downloaded through the pre-defined unique shared iFC identifier, ie when downloading Instead of downloading the specific iFC, the S-CSCF searches for and obtains the corresponding iFC set from the S-CSCF local database by downloading the identifier, thereby significantly reducing the data traffic of the download interface, and thereby reducing the HSS/ S-CSCF storage space

3 P17136 Occupy, increase system capacity and performance. However, the DSAI mechanism affects its application and its application effects to some extent due to the sharing of iFC sets. The specific analysis is as follows:

(1) Generally, the shared iFC set is determined at the time of service deployment and does not change dynamically when the user subscribes to the service. That is, as long as the S-CSCF and the HSS support the shared iFC set, and the HSS configures the shared iFC set during service deployment, the shared iFC must be applied when the S-CSCF downloads the user service configuration data from the HSS. Set, but can not dynamically change the shared iFC set or selectively download the shared iFC set associated iFC.

(2) Further, there is no necessary connection between the iFC associated with the shared iFC set and the iFC associated with the DSAI. That is, the iFC associated with the shared iFC set can be different or the same as the iFC associated with the DSAI. Therefore, if the iFC set associated with the DSAI is included or partially included by the iFC set associated with the shared iFC set, there is an overlap between the iFC set associated with the shared iFC set and the iFC set associated with the DSAI, that is, part of the iFC is simultaneously Associated with the shared iFC set and DSAI, then the DSAI is inactive and will inevitably cause the shared iFC set to be blocked by the iFC associated with the DSAI. At this time, if the shared iFC set is applied when downloading the user service configuration data, the blocked iFC is incorrectly downloaded by the HSS.

(3) Therefore, the DSAI mechanism is used to notify the HSS that the blocked iFC does not need to be downloaded to the S-CSCF. However, due to the application of the shared iFC set, the blocked iFC is still downloaded to the S-CSCF by the HSS, resulting in the DSAI mechanism not being reached. The effect of its application. In summary, the current DSAI mechanism and the application of the shared iFC set have some matching defects, which may cause the initial filtering rules to be downloaded correctly by the HSS. In a sense, this flaw affects the application of the DSAI mechanism and its application effects. SUMMARY OF THE INVENTION In view of one or more of the problems described above, the present invention provides an initial filtering rule configuration method and an initial filtering rule downloading and processing method using an initial filtering rule configuration method, which is provided by a provider network when the network provider performs service deployment. The system applies the present invention to reasonably configure the shared iFC set and the DSAI to ensure that the shared iFC set and the DSAI mechanism are not affected in actual application, thereby solving the initial filtering rule caused by the DSAI mechanism and the shared iFC set application in the IMS service configuration. The problem that the HSS may not be correctly downloaded may be implemented, and the correct download process of the user service configuration data is realized, and the application of the DSAI mechanism and its application effect are ensured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 5 is a flow chart of an initial filtering rule configuration method according to an embodiment of the present invention. As shown in FIG. 5, the method includes: Step S502: A network element entity pre-configures a shared initial filtering rule set and an initial filtering rule set related to dynamic service activation information.

6 P17136 Step S504: The network element entity checks the legality of the shared initial filtering rule set and the initial filtering rule set related to the dynamic service activation information. Step S506: When the shared initial filtering rule set and the initial filtering rule set related to the dynamic service activation information do not affect each other's service functions, determine that the check result is legal, and share the initial filtering rule set and the dynamic service activation information. If the related initial filtering rule set has an impact on the business function of each other, it is determined that the check result is illegal and returns to step S502 for reconfiguration until the check result is legal. The network element entity is a home user server or an operation and maintenance center. In the case where the shared initial filtering rule set configured by the network element entity and the initial filtering rule set related to the dynamic service activation information do not intersect, determine the shared initial filtering rule set and the dynamic service activation information. The initial filter rule set of ι has no effect on each other's business functions, and the check result is legal. In the case where the shared initial filtering rule set configured by the network element entity and the initial filtering rule set related to the dynamic service activation information partially intersect, determining the shared initial filtering rule set and the initial filtering rule set related to the dynamic service activation information to each other The function has an effect and the result of the check is illegal. In the case that the shared initial filtering rule set configured by the network element entity includes the initial filtering rule set related to the dynamic service activation information, determining that the shared initial filtering rule set and the initial filtering rule set related to the dynamic service activation information generate business functions for each other Impact, the inspection result is illegal. When the shared initial filtering rule set configured by the network element entity is included in the initial filtering rule set related to the dynamic service activation information, determining the shared initial filtering rule set and the initial filtering rule set related to the dynamic service activation information No effect, the result of the inspection is legal. The above initial filtering rule configuration method can be used for the IP multimedia subsystem. An initial filtering rule downloading and processing method using the foregoing initial filtering rule configuration method according to another aspect of the present invention includes: the network element entity preliminarily adopts an initial filtering rule configuration method to configure an initial related to dynamic service activation information in the service configuration data. Filtering the rule set and/or sharing the initial filter rule set; and downloading the service configuration data from the network element entity and performing subsequent processing if the service trigger is required. The network element entity is a home user server or an operation and maintenance center. The above initial filtering rule downloading and processing method is used for the IP Multimedia Subsystem. Specifically, the method for configuring an initial filtering rule according to an embodiment of the present invention may include the following steps:

P17136 Step 1: When the network provider performs service deployment, define a shared iFC set or a DSAI associated iFC set. Step 2: Perform, by the network element entity, the validity check of the iFC set definition of the shared iFC set or the DSAI association, and the processing logic includes: inputting the iFC set associated with the shared iFC set or the iFC set associated with the DSAI to satisfy the determination condition, and then outputting the configuration If the request is successful, the output configuration request fails if the judgment condition is not met. Step 3: If the configuration request is successful, it indicates that the legality check is passed, and the iFC set associated with the shared iFC set or the DSAI is allowed to be defined. Otherwise, the process returns to step 1 and is redefined. The network element entity in step 2 is not limited to a home subscriber subscription server (HSS), and includes an Operation & Maintenance Center (OMC). The determination of the determination condition in step 2 means that the iFC set configuration associated with the input shared iFC set or the iFC set configuration of the DSAI association does not affect each other's business functions. In the second step, the determination condition is not satisfied, that is, the iFC set configuration associated with the input shared iFC set or the iFC set configuration of the DSAI association has an interaction between the business functions of each other. The decision condition described in step 2 covers the scenario description of the degree of association of the iFC set with all inputs in step one, including the iFC set being associated with only one of the inputs, the part of the iFC set being associated with all inputs, and all the iFC sets being associated with all inputs. . The determination condition described in the second step includes that the iFC set associated with the scene sharing iFC set does not intersect with the iFC set associated with the DSAI. In this scenario, there is no impact on the business functions of each other, and the determination condition is satisfied. The determination condition described in the second step includes the intersection of the iFC set associated with the scene sharing iFC set and the iFC set part associated with the DSAI. In this scenario, the service functions of each other are affected, and the determination condition is not satisfied. The determination condition described in the second step includes that the iFC set associated with the scene sharing iFC set includes the iFC set associated with the DSAI. In this scenario, the service functions of each other are affected, and the determination is not satisfied. The determination condition described in step 2 includes that the iFC set associated with the scene sharing iFC set is included in

The iFC set associated with the DSAI has no effect on each other's business functions in this scenario, and the judgment conditions are met. Figure 6 is a diagram of a method logic for iFC download and processing in accordance with an embodiment of the present invention. In

8 P17136 In the logical block diagram of this method, the shared iFC set configuration request and the DSAI configuration request are input as inputs, and the output is the shared iFC set configuration result and the DSAI configuration result, and the scene description is used as the determination condition basis of the method logic. The specific method processing logic is as follows: input the shared iFC set configuration request, and the iFC set associated with the iFC set configuration request is shared by the network element entity such as the HSS or the OMC, and the iFC in the iFC set is sequentially queried to be associated with the DSAI, and then the association is performed. The degree of output outputs the shared iFC set configuration result, that is, the configuration is successful or the configuration fails. The DSAI configuration request is input, and the network element entity such as the HSS or the OMC is configured to request the associated iFC set according to the DSAI configuration request, and sequentially query whether the iFC in the iFC set is associated with the shared iFC set, and output the DSAI configuration result according to the degree of association, that is, the configuration is successful or Configuration failed. The extent to which the iFC is associated with the shared iFC set and the DSAI, that is, several scene descriptions referred to herein, is used as a basis for determining the method output, see FIG. 7A to 7D illustrate a scenario 4 required for applying the iFC download and processing method in an embodiment of the present invention, that is, exemplifying several possibilities between a DSAI-associated iFC set and a shared iFC set-associated iFC set. The contact diagram. Scenario 1: No association, see Figure 7A. The iFC is only associated with the shared iFC set or DSAI. In other words, the iFC set associated with the shared iFC set and the iFC set associated with the DSAI do not intersect. In this scenario, the DSAI service has no effect on the shared iFC set service. Therefore, the system processing logic method output configuration is successful. Scenario 2: Partial association, see Figure 7B. Part of the iFC is associated with the shared iFC set and the DSAI at the same time. In other words, the iFC set associated with the shared iFC set and the iFC set part of the DSAI are partially intersected. In this scenario, the DSAI service affects the application of the shared iFC set service. Therefore, the system processing logic method output configuration fails. Scenario 3: All associated, see Figure 7C. All iFCs are associated with the shared iFC set and DSAI at the same time. In other words, the iFC set associated with the DSAI contains the iFC set associated with the shared iFC set. In this scenario, the DSAI service has no effect on the shared iFC set service application. Therefore, the system processing logic method output configuration is successful. Scenario 4: All associated, see Figure 7D. All iFCs are associated with the shared iFC set and DSAI at the same time. In other words, the DSAI associated iFC set is included in the iFC set associated with the shared iFC set. In this scenario, the DSAI associated iFC set is used as one of the iFC sets associated with the shared iFC set.

9 P17136 The subset has an impact on the shared iFC set business application, so the system processing logic method output configuration fails. Figure 8 depicts a high level block diagram of a service deployment using iFC download and processing methods in accordance with one embodiment of the present invention. Step S802, after the provider network receives the request for the new service, the method then proceeds to step S804. Step S804, the service code related to the new service request is deployed on at least one application server in the provider network, or is loaded onto multiple application servers if it is desired to share. The method then proceeds to step S806. Step S806, the names of all application servers holding the new service are stored in the HSS of the provider network. The method then proceeds to step S808. Step S808, the network provider allocates one or more unique DSAI-tag identifiers for the new service, and deploys in the provider's HSS and all application servers holding the new service. A DSAI instance is uniquely identified by the user ID and the DSAI-tag identifier. The method then proceeds to step S810. Step S810, the network provider defines service configuration information related to the new service, and assigns a default value to the formal parameter in the service configuration. At the same time, the shared iFC set is defined, and the shared iFC set is associated with multiple iFCs. The system applies the iFC download and processing method to check the legality of the configuration. If the configuration fails, redefine the iFC set associated with the shared iFC set. The method then proceeds to step S812. Step S812, the network provider defines an iFC associated with the DSAI-tag identifier, and the system applies the iFC download and processing method to verify the validity of the configuration. If the configuration fails, redefine the iFC set associated with the DSAI-tag identifier. At this time, the DSAI instance is not generated because the user has not made a reservation. The method then proceeds to step S814. Step S814, the user subscribes to a new business. The method then proceeds to step S816. Step S816, the network provider provides the formal parameter in the service configuration by using the user-specific actual parameter, and provides the service information field of the service information component of the new service. At this point, the DSAI instance has been generated because the user has reserved a new service. The method then proceeds to step S818.

10 P17136 In step S818, the activation status of the DSAI uniquely indicated by the user identifier and the DSAI-tag identifier is activated by default and saved in the HSS 104. Generally, the activation status of the DSAI can only be updated by the AS 106 through the Sh interface, reflecting the dynamic information of the current user subscription service. At this point, the deployment of the new service is completed, and the shared iFC set and DSAI are configured, and the method then exits. The invention provides a legality-risk certificate for the DSAI configuration and the shared iFC set configuration by the network system when the network provider performs service deployment, which can prevent the DSAI and the shared iFC set from affecting each other at the same time, thereby achieving The HSS correctly downloads the purpose of the initial filtering rules. At the same time, there is no need to make any changes to the existing interface and configuration, and the application of the DSAI mechanism and its application effects are guaranteed. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
