In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

In order to facilitate statistical charging of local services, a standard Ga interface is used between the MEC and the CG, the MEC server is connected with the CG through a transmission network, and charging related information collected by the MEC equipment is reported to the CG.
Based on the structure, local service charging is carried out based on the MEC server and the CG, wherein the MEC server side comprises the following steps:

step 302, the MEC server identifies the mobile terminal executing the service by monitoring.
And 304, identifying whether the service message is a local service message or not aiming at the service message corresponding to the mobile terminal.
The MEC server monitors S1 signaling and service plane data, thereby identifying the service packet and identifying the IP address of the terminal corresponding to each service data. And identifying whether the service message is a local service message or not aiming at each service message. If yes, identifying a local service message corresponding to the mobile terminal, and executing step 306; if not, identifying that the local service message is not the local service message corresponding to the mobile terminal, and executing a normal processing flow, such as forwarding the service message.
Step 306, counting the local service message to generate local charging information.
And 308, sending the local charging information to a charging gateway so as to charge the local service of the mobile terminal through the charging gateway.
When the local service message corresponding to the mobile terminal is identified, the data such as the flow corresponding to the local service message are counted to generate local charging information, and then the local charging information is sent to the CG so as to generate a ticket by adopting the CG and charge the local service of the mobile terminal.
The CG side steps are as follows:
referring to fig. 4, a CG-side step flow diagram of a local service charging method embodiment of the present invention is shown.
Step 402, receiving local charging information sent by the MEC server.
Step 404, determining the mobile terminal executing the local service according to the IP address in the local charging information.
Step 406, adding the local charging information into a ticket of the mobile terminal, and sending the ticket to a charging system to charge the local service of the mobile terminal.
And the CG receives the local charging information sent by the MEC server, acquires an IP address from the local charging information, identifies the mobile terminal of the local service by adopting the IP address, adds the local charging information into a ticket of the mobile terminal, and sends the ticket to the BOSS for charging, thereby realizing the charging of the local service of the mobile terminal.
In the embodiment, the MEC server is connected with the CG, and the MEC server forwards the local service and the network service, so that the MEC server is adopted to count the local service to obtain the local, the obtained local charging information is sent to the CG, the CG generates a ticket to execute the charging of the local service, and the local service can be accurately counted and charged.
On the basis of the above embodiments, the present embodiment further discusses a process of performing local service charging based on the MEC server and the CG.
Referring to fig. 5, a flowchart of the MEC server side of another embodiment of the local service charging method of the present invention is shown.
Step 502, the MEC server identifies the mobile terminal executing the service by monitoring.
Step 504, aiming at the service message corresponding to the mobile terminal, judging the type of the service message.
The MEC server monitors S1 signaling and service face data, acquires and identifies service messages, identifies IP addresses of terminals corresponding to each service data, and identifies types of the service messages. The MEC server monitors an S1 signaling of the terminal, acquires GTPu tunnel information of the terminal, and acquires an IP address of the terminal from a service message according to the GTPu tunnel information in user plane data. In this embodiment, the service packet may be divided according to uplink and downlink, so that it may be determined that the service packet is an uplink service packet or a downlink service packet. Step 506 is performed for the uplink service packet, and step 514 is performed for the downlink service packet. Step 506, identifying a destination address of the uplink service packet for the uplink service packet corresponding to the mobile terminal.
Step 506, determining whether the destination address of the uplink service packet is the address of the local server.
In this embodiment, for the uplink service, the service packet is sent from the base station to the local server or the core network through the MEC server, and for the local service, the service packet is sent to the local server. Therefore, whether the service message is sent to the local server can be judged according to the shunting rule, that is, the destination address of the uplink service message can be obtained, and then whether the destination address is the address of the local server can be judged, and the address of the local server can be carried in the rule configured in advance. When the destination address is the address of the local server, executing step 512; when the destination address is not the address of the local server, step 514 is performed.
Step 508, determine whether the downlink service packet is a packet sent by the local server.
In this embodiment, for the downlink service, the service packet is forwarded to the base station by the core network or the local server through the MEC server, where the core network sends the service packet through the GTPU tunnel. Therefore, whether the downlink service message is a message sent by the local server can be determined according to the source judgment of the downlink service message. If the downlink service message is a message sent by the local server, execute step 512; if the downlink service packet is an intercepted packet from the GTPU tunnel, it is not a packet sent by the local server, and step 514 is executed.
Step 510, determining that the service packet is not a local service packet.
Step 512, determining that the service message is a local service message.
For the uplink service: the destination address is the address of the local server, the uplink service packet is determined to be the local service packet, and step 516 is executed. When the destination address is not the address of the local server, it is determined that the uplink service packet is not the local service packet, and a normal processing procedure may be performed, for example, the uplink service packet is sent to the core network device.
For downlink traffic: when the downlink service packet is a packet sent by the local server, it is determined that the downlink service packet is a local service packet, and step 516 is executed. When the downlink service message is a message intercepted from the GTPU tunnel, the message issued by the public network is a message not issued by the local server, the MEC server can only forward the downlink service message without flow statistics, and the flow of the public network service is counted by the core network equipment.
And 514, acquiring the IP address of the mobile terminal corresponding to the local service message.
Step 516, recording the corresponding start time and end time according to the local service message, and counting the data traffic corresponding to the local service message.
And 518, generating local charging information according to the IP address, the starting time, the ending time and the data flow.
Step 520, sending the local charging information to a charging gateway, so as to charge the local service of the mobile terminal through the charging gateway.
The method comprises the steps of counting the uplink and downlink local service messages, acquiring the IP addresses of the mobile terminals corresponding to the local service messages, recording the starting time and the ending time of the corresponding local services according to the local service messages, and counting the data traffic of the local service messages between the starting time and the ending time, wherein the data traffic comprises uplink traffic and/or downlink traffic. The parameters such as the IP address, the start time, the end time, and the data traffic are used to generate local charging information, which may also include other parameters, such as the type and the base station identifier. And then sending the local charging information to a charging gateway so as to charge the local service of the mobile terminal through the charging gateway.
The MEC server reports charging related original information, that is, local charging information, between the CG through the Ga interface, where the local charging information includes a newly added record type MEC-CDR, the MEC-CDR represents local service charging information counted by the MEC server, and the local charging information shown in table 1 includes, but is not limited to, the following parameters:
parameter(s) Properties (M: optional parameters; O: optional parameters)
Record type (MEC-CDR) M
Type of charge (local service) M
Terminal IP address M
Enb ip address O
Sgw ip address O
List of charging information M
TABLE 1
The local charging information includes a charging information list, the charging information list has a plurality of records, and main information included in each record is shown in table 2:

Figure BDA0001161450270000101
TABLE 2
The global identity of the base station refers to global identity of the base station, each base station has a global unique identity at present, and an IP address is a concept on transmission and is unique in a subnet. I.e. global identity of base station Glb id is a concept at S1AP level and IP address is a concept on transport, so a base station can have multiple IPs but only one Glb id.
Therefore, the MEC server reports the local charging information, namely the data of the MEC-CDR ticket type, to the CG through the Ga interface, and the CG carries out charging statistics, and the specific steps are as follows:
referring to fig. 6, a CG-side step flow diagram of another embodiment of the local service charging method of the present invention is shown.
Step 602, receiving the local charging information sent by the MEC server.
Step 604, obtaining the IP address and the execution time of the local service from the local charging information, and determining the terminal identifier corresponding to the IP address according to the execution time.
Step 606, the mobile terminal corresponding to the terminal identifier is determined as the mobile terminal executing the local service.
And the CG receives the local charging information sent by the MEC server, acquires the IP address and the execution time of the local service from the local charging information, determines the terminal identification corresponding to the IP address in the execution time of the local service, and determines the mobile terminal corresponding to the terminal identification as the mobile terminal executing the local service, namely uniquely determines the mobile terminal corresponding to the local charging information.
In an optional embodiment of the present application, acquiring an IP address and an execution time of a local service from the local charging information, and determining a terminal identifier corresponding to the IP address according to the execution time includes: acquiring an IP address from the local charging information, and determining a charging information list corresponding to the local charging information; acquiring the starting time and the ending time of the local service from the charging information list, and determining the execution time of the local service by adopting the starting time and the ending time; and searching public network charging information uploaded by the PGW according to the execution time, and determining the IMSI (International Mobile Subscriber identity) corresponding to the IP address.
The MEC-CDR has no IMSI information of the user, only has the IP address of the user, and the IP address is possibly changed after the terminal is detached every time and reattached, so the IP address cannot be used as the unique identifier of the terminal, the IMSI of the terminal is not changed, if the IP address is not matched with the IMSI, the terminal cannot be accurately charged, and the IP address can be used for being associated with the IMSI. Usually, the mobile network is closed, and the IP address is allocated by the core network, so the core network may store the association relationship between the IP address and the IMSI. Specifically, after the terminal is attached and before the terminal is detached, the IP address allocated to the terminal by the core network is not changed, so that the IMSI can be determined by inquiring the correspondence between the UE IP and the IMSI according to time.
The IP address is obtained from the local charging information, then a charging information list corresponding to the local charging information is searched, the starting time and the ending time of the local service are obtained from the charging information list, and the difference value of the starting time and the ending time is used as the execution time of the local service. And searching public network charging information (PGW-CDR) uploaded by the PGW according to the execution time, acquiring the corresponding relation between the UE IP and the IMSI from the PGW-CDR, and determining the corresponding IMSI so as to uniquely determine the mobile terminal executing the local service.
Step 608, adding the local charging information to a ticket of the mobile terminal, and sending the ticket to a charging system to charge the local service of the mobile terminal.
Then adding the local charging information into the call ticket of the mobile terminal, and sending the call ticket to the BOSS system, so that the BOSS system distinguishes local flow from the call ticket reported by CG, and charges the flow according to the charging rule of the local flow.
In the embodiment of the invention, the system architecture is changed, namely, an interface between the MEC and the CG is increased, local flow statistics based on the UE IP is carried out on the MEC, the CG searches the corresponding IMSI according to the UE IP and the time period, the local flow reported by the MEC is added into the original ticket of the terminal, and the BOSS generates the ticket according to the local flow and the specific charging rule, thereby effectively solving the charging problem of the user flow after the local shunt equipment is deployed.
