The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without the creative work are all within the scope of the present invention.

The charging processing method in the first embodiment of the charging processing method of the present invention may include: the core network node generates a charging data record corresponding to a group of MTC devices according to charging rule information used for charging a group of MTC devices, The core network node performs charging processing on a group of MTC devices according to the charging data record.

Specifically, the core network node may be an MME (Mobility Management Entity), an SGSN (Serving GPRS Support Node), a GGSN (Gateway GPRS Support Node), and an S-GW ( Service Gateway, Service Data Gateway), P-GW (PDN Gateway, Packet Data Gateway), at least one of the charging domains. When the MTC device is charged, the MTC devices with the same attributes are generally charged in the same charging mode. For example, different MTC devices belonging to the same user generally perform charging according to the same charging method. Therefore, the MTC devices with the same attributes are grouped into one group. For the MTC devices in the same group, the same charging method is used for charging. In addition, according to M2M pass The characteristics of small single-time data and large number of times can record the charging events of each communication process of a group of MTC devices, and collect the charging events of the recorded communication processes together according to certain rules. fee. The core network node first obtains charging rule information for charging a group of MTC devices, and generates a CDR corresponding to a group of MTC devices according to the charging rule information. The CDR includes a charging event of multiple communication processes of multiple MTC devices in a group of MTC devices. The core network node performs unified charging processing on the group of MTC devices according to the CDRs of the group of MTC devices. The process in which the core network node performs charging for a group of MTC devices according to the generated charging data record may be: The other nodes in the core network node send the generated CDRs to the charging domain in the core network node by using the charging trigger function. . User information is recorded in the charging domain, and the user is charged according to the CDR.

In this embodiment, the core network node generates charging data records corresponding to a group of MTC devices according to charging rule information used for charging a group of MTC devices, and calculates a group of MTC devices according to the charging data records. The fee is realized, and the charging operation is performed once for the multiple communication process of a group of MTC devices, and the network congestion caused by the excessive amount of charging data generated by the billing for each communication process in the M2M communication is solved. The problem.

Further, the charging rule information acquired by the core network node includes a rule for uniformly performing charging processing for multiple communication processes of a group of MTC devices and a rule for performing charging processing for multiple communication processes of a group of MTC devices respectively. The charging data record indication includes a group charging data record indication and a device charging data record indication. If the charging data record indication is a group charging data recording indication, the core network node determines to perform group charging on a group of MTC devices; If the charging data record indication is a device charging data record indication, the core network node determines to perform charging separately for each communication process of the MTC device, that is, charging based on the bearer.

1 is a flowchart of Embodiment 2 of a charging processing method of the present invention. As shown in FIG. 1, the charging processing method in this embodiment may include:

Step S101: The core network node determines, according to the charging data record indication, performing group charging on a group of MTC devices or charging based on the bearer.

Specifically, each communication process of the MTC device needs to be performed through one bearer, and charging is performed based on the bearer, that is, charging is performed separately for each communication process of the MTC device. Group accounting combines the communication processes of a group of MTC devices to perform billing together. If the core network node determines that the charging data record indication is the group charging data record indication, the group charging process is performed, and step S102 is performed. If the core network node determines that the charging data record indication is the device charging data recording indication, the bearer is based on the bearer. Billing In step S106, if the core network node determines that the charging data record indication includes both the group charging data record indication and the device charging data record indication, the group charging is performed and the charging is performed based on the bearer, and step S107 is performed.

Step S102: If the core network node determines to perform the group charging process, determine the charging rule information. Specifically, if the core network node determines that the charging data record indication is a group charging data recording indication, that is, performing group charging, the core network node determines the obtained charging rule information. If the charging rule information is a signaling volume based group or a monitoring and alarm event count based group, step SI 03 is performed, if the charging rule information is time window based If the group (based on the time window grouping) or the location limit based group, the step S104 is performed, and if the charging rule information is a radio based group, the step S105 is performed.

Step S103: The core network node generates a charging data record according to the signaling amount or the amount of user data or the number of monitoring events or the number of alarm events.

Specifically, the charging rule ¹ J information may be a signaling volume based group or a monitoring and alarm event count based group. If the charging rule 'J information is a signaling volume based group, the core network node counts the amount of signaling data when a group of MTC devices perform communication services, and records charging information. If the charging rule 'J information is monitoring and alarm event count based grou , the core network node counts the amount of monitoring alarm event data when a group of MTC devices conducts communication services, and records charging information. If the charging rule information is grouped according to the amount of user data, the core network node counts the amount of communication data of each user in a group of MTC devices, and records the charging information. The core network node aggregates the recorded charging information of the MTC device communication service together, and generates a group charging data record that records the charging status of a group of MTC devices.

Step S104: The core network node charges a group of MTC devices at a corresponding rate according to the controlled time period and/or the geographic area, and generates a charging data record.

Specifically, the charging rule ¹ J information may be time window based group or location limit based grou. If the charging rule information is time window based grou, the core network node determines the length of the communication time of a group of MTC devices according to a preset time window, and the time length is within the controlled time period in the preset time window. The length of time is outside the preset time window and is outside the controlled time period. The core network node charges the MTC communication process with the communication time length within the controlled time period and the controlled time period at a preset different rate, and records the charging information. If the billing rule letter The information is location limit based group, and the core network node determines, according to a preset geographic area, whether the location where a group of MTC devices communicates is within a preset geographic area or outside the area. The core network node charges the MTC communication process within the geographic area and outside the geographical area at a preset different rate, and records the charging information. The core network node aggregates the recorded charging information of the MTC device communication service together, and generates a group charging data record that records the charging status of a group of MTC devices.

Step S105: After collecting, by the core network node, a charging event of a preset proportion of devices in the MTC device, generating a charging data record.

Specifically, the charging rule information may be a radio based group. If the charging rule information is radio based grou, the core network node records the identity of the MTC device that communicates when the MTC device communicates, and records the charging information of the communication. When the core network node determines that more than one preset proportion of the MTC devices in a group of MTC devices have communicated, the core network node collects the recorded charging information together to generate a record for recording a group of MTC devices. Group billing data record for the fee situation.

It should be noted that, in the foregoing steps S103 to S105, the core network node determines the communication process of the MTC device according to the charging rule information from different dimensions, and the determining method may be performed separately or simultaneously. of. For example, the core network node can perform statistics on the signaling data volume of a group of MTC devices, and charge the MTC devices located in the preset area and outside the preset area at different rates, when the group of MTC devices has exceeded When the preset proportion of the MTC devices have communicated, the group charging data records are generated together with the charging information of all the recorded MTC devices in the group.

Step S106: If the core network node determines to perform the bearer-based charging process, generate a charging data record corresponding to the bearer of each MTC device.

Specifically, if the core network node determines that the charging data record indication is the device charging data recording indication, that is, charging based on the bearer, the core network node records the charging information of each communication of the MTC device. The core network node collects the billing information of the recorded MTC device communication service together, and generates a device billing data record that records the charging status of the plurality of MTC devices.

Step S107: If the charging data record indication includes both the group charging data record indication and the device charging data record indication, the core network node performs both group charging and the bearer into the frH "fee" for the MTC device.

Specifically, if the charging data record indication includes both the group charging data record indication and the device charging data record indication, the core network node generates a group of MTC devices according to the charging policy rule according to the method of steps S103 to S105. Corresponding group charging data record; and the core network node further generates a device charging data record corresponding to the bearer of each MTC device according to the method of step S106. Step S108: Generate a charging data record by using a preset duration interval or a preset traffic interval. Specifically, the charging rule information acquired by the core network node further includes generating a charging data record by using a preset duration interval or a preset traffic interval. In the foregoing steps S103 to S107, after the core network node generates the group charging data record or the device charging data record according to the charging rule information, the core network node further uses the preset duration as the interval according to the rules in the charging rule information. The preset traffic is an interval, and controls rules for generating a group charging data record or a device charging data record. For example, if the charging data record indication is a group charging data record indication, when the group charging data record is generated according to the preset time interval, the core network node will record the record according to the group charging data record every preset time interval. The charging information of the MTC device communication service is collected together to generate a group charging data record that records the charging status of a group of MTC devices; when the group charging data record is generated according to the preset traffic interval, the core network node pair is calculated according to the group. The fee data record indicates that the total data amount of the recorded MTC device communication service charging information is recorded, and when the total data amount of the charging information reaches a preset traffic interval, the core network node records the recorded MTC device communication service. The charging information is gathered together to generate a group charging data record that records the charging status of a group of MTC devices. If the charging data record indication is the device charging data record indication, when the device charging data record is generated according to the preset time interval, the core network node charges the recorded MTC device communication service every preset time interval. The information is collected together to generate a device charging data record that records the charging status of the plurality of MTC devices. When the charging data record is generated according to the preset traffic interval, the core network node records the total charging information of the MTC device communication service. The amount of data is counted. When the total amount of data of the billing information reaches a preset traffic interval, the core network node collects the billing information of the recorded MTC device communication service together, and generates and records the billing of multiple MTC devices. Device billing data record for the situation. If the charging data record indication includes both the group charging data record indication and the device charging data record indication, the group charging data record and the device charging data record are separately generated according to the foregoing method.

Step S109: The core network node performs charging processing on the MTC device according to the charging data record. Specifically, the core network node performs charging processing on the MTC device according to the group charging data record or the device charging data record generated according to the charging data record indication and the charging rule information in the foregoing steps S103 to S108. If only the group charging data record is recorded, the core network node uniformly performs charging processing on the group MTC device according to the group charging data record; if only the device charging data record, the core network node separately charges the MTC device. If there is a group accounting data record and a device charging data record, the core network node selects one of the MTC devices to perform charging processing according to a preset rule. In this embodiment, the core network node determines, by using the charging data record indication, a method of performing group charging or bearer charging on the MTC device, and determining a specific method for group charging the group of MTC devices by acquiring charging rule information. The process of charging the MTC device in different charging modes according to the application scenario of the MTC device and the user requirements is implemented, the generation process of the charging data record of the MTC device is optimized, the amount of charging data is reduced, and the amount of charging data is solved. The problem of network congestion caused by too large.

Further, the charging data record generated by the core network node includes a group charging id, and the charging domain in the core network node performs a CDR corresponding to a group of MTC devices according to the group charging id in the charging data record. Perform unified billing processing. The group charging id is an identifier for charging a group of MTC devices, and the core network node performs the same charging process for the MTC device with the same group charging id.

Specifically, before the MTC device performs the communication service, the core network node first needs to obtain the charging rule information corresponding to the MTC device, and the core network node determines the charging mode and the specific charging rule for the communication service of the MTC device by using the charging rule information. After that, the MTC device can perform communication services. The MTC device first sends a session request message to the core network node when the attach or multi-PDN (Packet Switching Network) is established, requesting to establish a session channel with the core network node, where the session request message includes the MTC device.

The PCRF node is responsible for storing and allocating charging rules for all devices in the network when dynamic charging rule information is used. The corresponding charging rule information of the MTC device and a group of MTC devices is stored in the PCRF according to the device identification and the group identifier of the MTC device.

Step S203: The core network node receives a session establishment response message fed back by the PCRF, where the session is established. The response message includes charging rule information corresponding to the group identifier, where the charging rule information includes a charging data record indication.

Specifically, the PCRF determines, according to the group id included in the session establishment message sent by the core network node, the charging rule information that needs to be performed for the MTC device, where the charging rule information includes an accounting data record indication. The PCRF allocates the same charging rule information for the MTC devices with the same group id, including the same charging data record indication. After allocating the charging rule information to the MTC device, the PCRF feeds back the session establishment response message to the core network node, where the session establishment response message includes the charging rule information corresponding to the group id, and includes the charging data record indication corresponding to the group id. The core network node can complete the process of generating a charging data record for the communication process of the MTC device according to the charging data record indication.

Step S204: The core network node feeds back a session request response message to the MTC device, and establishes a session channel of the MTC device.

Specifically, after receiving the charging rule information sent by the PCRF, the core network node sends a session request response message to the MTC device to allow the MTC device to perform the communication service.

It should be noted that, in this embodiment, the PCEF (Policy Control and Charging Enforcement Function) node is sent, received, and recorded in the core network node, and the PCEF node is generally It can be configured in the P-GW in the core network node.

In this embodiment, during the establishment of the session, the PCRF allocates the charging rule information of the MTC device to the core network node, so that the core network node can perform the charging operation on the communication service of the MTC device, and complete the dynamic charging.
