An apparatus, a method, and a recording medium for setting a rule.

In general, a mobile communication system sets a service quality policy and a billing rule for service use, and provides services to terminals according to a set policy and a billing rule. For this purpose, the Policy and Charging Rules Function (PCRF) receives service information from an Application Function (AF) or a Subscription Profile Repository (SPR) And generates a policy and a Charging Control Rule (PCC rule). The PCRF then provides the generated PCC rules to the Policy and Charging Enforcement Function (PCEF). The PCEF then provides the QoS (Quality of Service) service according to the service flow to the terminal based on the PCC rule.

However, conventionally, all subscribers must have PCC information for each subscriber. Therefore, when configuration information or parameters of PCC rules need to be changed or added, configuration information or parameters of PCC rules are changed There is a problem that the package of the PCC rule must be changed accordingly.

The Subscription Profile Repository (SPR) 110 includes subscriber profile information (or subscriber information) which is subscription information of subscribers, for example, the type of service permitted to the subscriber, information on subscription and activation, Service method information, charge method information as billing information of the subscriber, charge plan information, access point name (APN) of the subscriber, information on the subscriber category, and the like. Upon receiving the subscriber information request from the PCRF 130, the SPR 110 transmits the requested subscriber information to the PCRF 130 in response to the subscriber information request.

The application function (AF) 120 may allow subscriber stations to negotiate service quality information requests such as VoLTE (Voice Over LTE) using a Session Initiation Protocol (SIP) And generates service information using a session description protocol (SDP) to be exchanged. The service information generated by the AF 120 may include an Internet Protocol (IP), a port, a media type, bandwidth, application information of an application function, recording information of an application function, . Then, the application function 120 transmits service information to the PCRF 130 after session connection with the PCRF 130, and requests control of the service.

The PCRF 130 is generally present in a wireless data network and generates PCC rules for QoS and charging in cooperation with the SPR 110 and the AF 120 in a heterogeneous network such as WiFi and eHRPD as well as WCDMA / LTE . In other words, the PCRF 130 generates PCC rules based on subscriber (profile) information received from the SPR 110 and service information received from the AF 120. The PCRF 130 can transmit the PCC rule generated at the request of the PCEF 140 to the PCEF 140 and can transmit the PCC rule at the PCRF 140 even if there is no request from the PCEF 140 .

The PCEF 140 receives a PCC rule from the PCRF 130 and receives the PCC rule and provides a QoS control and a billing information control service according to the service flow to the terminal based on the received PCC rule For example, PDN-GW.

The following is an example of attributes managed and mapped to the key value of the database 131 according to the present embodiment.

One key may have predefined PCC rule names between up to eight PCRFs 130 and PCEF 140 and may include a Deactivation Timer to indicate the maximum expiration time to which applicable PCC rule names apply. Value as an attribute.

The data values of the parameters? To? Of the PCC rule defined as in the above-mentioned [Table 1] to [Table 5] are combined with each other by the number of possible combinations according to the predetermined order for the components, A value is defined.

For example, as shown in Table 6 below, the data value '0001' of the parameter 'HD Premium Pack' of the service type of the component 1 and the data of the 'subscription and activation' of the parameter of the subscription and activation of the component 2 The data value '00' of the parameter 'postpaid plan', the data value '22' of the parameter '34 plan' of the fare plan information, and the component ⑤ A key value '00010003002201' is generated by sequentially combining the data value '01' of the parameter 'Internet' of the APN information. In this way, the PCC rules defined in the above [Table 1] to [Table 5] A number of key values are generated by combining the data values of the parameters? To? Of the components?

KEY  value Attribute # 1 to # 8
(PCC Rule name) Attribute # 9
(Deactivation Time Value) 00010003002201 Rulename # 1 Monthly 00020002002A01 Rulename # 2 Daily 00030001003A01 Rulename # 3 Hourly 00040001003E01 Rulebasename # 4 None .

Mapping each of the plurality of PCC rule names (PCC rule name) corresponding to each key value defined as described above so that it can be selected, and also mapping the PCC rule name corresponding to the key value to the Deactivation Time Value).

The database 131 according to the present embodiment is configured to map a key value (DB Table Key value) indicating a service type / service subscription / charge method / charge / APN information to a corresponding key value as shown in [Table 6] An attribute value, a PCC rule name (PCC Rulename), and an attribute (Deactivation Time Value Attribute) indicating an operation expiration period of the corresponding PCC Rulename.

In the database 131 according to the present embodiment, the key value may be generated, changed, or deleted through, for example, a command of the PCRF operator.

With the key value as described above, the communication service provider can easily differentiate the data QoS and the billing according to the service subscription / charge method (prepaid, postpaid) / charge / APN information of the subscriber. Particularly, it is possible to improve the performance and capacity of the PCRF because it is possible to select the PCC rule using one common database 131 by knowing only the subscriber information instead of having the PCC information for each subscriber.

In addition, by using only information of one common database 131, it is possible to easily change the PCC information (constituent elements and parameters of the PCC rules) in the PCRF so that it can be easily applied to all subscribers without having to modify each subscriber DB when a change event occurs It is possible. This simplifies PCC management and minimizes errors in PCRF operation.

The PCC rule selecting unit 133 according to the present embodiment is for generating a key value corresponding to subscriber information based on the database 131 and selecting PCC rule and operation expiration period information corresponding to the key value, If there is a request for PCC rule for the subscriber from the PCEF 140, based on the database 131, a data value of a component of the PCC rule corresponding to the subscriber information and a parameter of the corresponding component is searched, The retrieved data values are combined according to a predetermined order to generate one key value, and one PCC rule name corresponding to the generated one key value can be selected.

First, if the subscriber information is composed of 'HD Premium Pack', 'Subscription and Activation', the fare method is' postpaid plan ', the fare plan information is' 34 plan', and the APN information is' 0001 'corresponding to the' HD premium pack 'parameter, the data value' 0003 'of the' subscription and activation 'parameter, the' postpaid rate ' 00010003002201 'is generated by sequentially searching and combining the data value' 00 'of the parameter, the data value' 22 'of the' 34 charge 'parameter and the data value' 01 'of the' Internet 'parameter.

Next, referring to the database 131, a PCC rule name and an operation expiration period corresponding to the key value '00010003002201' generated as described above are searched. For example, as shown in [Table 7] below, the PCC rule name Attribute # 1 (HD_PREMIUM_MON_400K) is registered in the key value 0001003002201 and the Deactivation Time value is registered as Attribute # 9 (Monthly) , It means that it operates by applying Attribute # 1 (HD_PREMIUM_MON_400K) in Monthly unit.

KEY  value Attribute # 1
(PCC Rule name) Attribute # 9
(Deactivation Time Value) 00010003002201 HD_PREMIUM_MON_400K MONTHLY

That is, as shown in FIG. 5, when the subscriber information is registered in the HD premium pack service as " enrolled ", and the subscriber using the postpaid plan and the 34 rate plan is using the predefined PCC rule 'HD_PREMIUM_MON_400K' (predefined PCC Rule) to control the PCC by the end of the month.

If the user wishes to change the parameters of the tariff to be applied to the PCC rule 'HD_PREMIUM_MON_400K' from the 34 tariff to the 42 tariff, the PCC information of all the subscribers subscribed to the 42 tariff is not changed one by one, It is possible to easily provide the PCC change only by changing the fare plan information to 0x2A.

In addition, if 'HD_PREMIUM_MON_400K' is changed to another Rulename or Hourly unit, it can be easily changed by modifying / adding only the attribute value of the database 131.

The PCC rule transmitting unit 235 according to this embodiment is for transmitting the PCC rule name and operation expiration information selected by the PCC rule selecting unit to the PCEF 140. [
