The embodiment of the present application is mainly applied to a CDR between the CDF 102 and the CGF 103. Transmission. The Ga interface is used to transfer bills between the CDF 102 and the CGF 103. The Ga interface is commonly used in billing systems, such as Packet Switching (PS)/Evolved Packet Core (EPC), PS/EPC. In the core network, the PS/EPC network element (the CTF and the CDF are integrated) and the CGF transmit the charging data through the Ga interface. The Ga interface is implemented by the GTP protocol stack. The principle of the protocol stack is described in the 3GPP 32.295 standard document. In the 3GPP 32.295 standard, the GTP protocol defines CDR transmission and redirection functions, failure detection recovery, and prevention of re-single functions. The Bx interface is mainly used to connect the CGF103 and the BD104. It can be seen from FIG. 1 that the CTF 101 may include a service unit or a sub-unit, and the above-mentioned units complete the functions required by the CTF 101 together or separately, and the acquired core network CN domain name is also cached in the CTF 101.

As shown in FIG. 2, the embodiment of the present application provides a bill transfer method, which includes the following steps:

Step 201: The CDF sends a first suspected duplicate packet to the CGF, where the first suspect duplicate packet includes a sequence number of the target data packet.

In an embodiment, before step 201, the CDF completes the following steps: the CDF sends a target data packet to the first CGF, and if the CDF does not receive the response message sent by the first CGF within a preset time, the CDF goes to the first The second CGF sends a second suspicious duplicate packet with the same sequence number and the same CDR as the target data packet. After the first CGF can work normally, the CDF receives the Cause (Cuse) field of the first CGF transmission as "Node Survival Request (Node). The message of the Alive Request), the CDF replies to the first CGF with a message that the Cause field is "Node Alive Response". In an embodiment, the preset time is 9 seconds. Of course, the specific value of the preset time is not limited herein. In the preset time, the CDF may fail to receive the response message sent by the first CGF in time. Abnormal situation such as network interruption, first CGF failure, first CGF busy or insufficient first CGF resources.

In an embodiment, the first suspect duplicate packet may further include information such as a calling number and a call start time.

Step 202: After receiving the acknowledgement message sent by the first CGF, the CDF determines whether the acknowledgement message indicates that the first CGF receives the first suspect duplicate packet but does not receive the target data packet. Target confirmation message.

In an embodiment, the acknowledgement information includes a target acknowledgement message sent by the first CGF indicating that the first CGF receives the first suspected duplicate packet but does not receive the target data packet, and also includes the first CGF sent It does not belong to the target confirmation message, but other messages that are the same as the content of the target confirmation message reply, so a judgment is made here.

Step 203: If the acknowledgement message is the target acknowledgement message, the CDF sends, to the second CGF, a first request message for requesting the second CGF to output the CDR in the second suspected duplicate packet, where The second suspect duplicate packet includes a sequence number of the target data packet and the CDR.

In the embodiment of the present application, the CDF sends a first suspected duplicate packet containing the sequence number of the target data packet to the first CGF, and the CDF determines whether the acknowledgement message sent by the first CGF indicates that the first CGF receives the first suspected duplicate packet but does not receive. And the first request message for requesting the second CGF to output the CDR in the second suspicious duplicate packet to the second CGF, if the acknowledgement message is the target acknowledgement message, The phenomenon of heavy single phenomenon.

As shown in FIG. 3 and FIG. 4, the embodiment of the present application provides another method for transmitting a bill, including the following steps:

Step 301: The CDF sends a first suspected duplicate packet to the CGF, where the first suspect duplicate packet includes a sequence number of the target data packet.

Step 302: After the CDF receives the acknowledgement message sent by the first CGF, the CDF determines whether the acknowledgement message includes a target field, and if the acknowledgement message includes the target field, step 303 is performed; If the confirmation message does not include the target field, step 305 is performed.

Step 303: The CDF determines that the confirmation message is a target confirmation message indicating that the first CGF receives the first suspect duplicate packet but does not receive the target data packet.

Step 304: The CDF sends, to the second CGF, a first request message for requesting the second CGF to output a CDR in the second suspicious duplicate packet, where the second suspect duplicate packet includes the target data packet. Serial number and CDR.

Step 305: The CDF sends a second request message for deleting the second suspect duplicate packet to the second CGF.

In an embodiment, the Cause field of the target acknowledgment message may be 128 (Request accepted), and the target acknowledgment message may carry the type field of the target data packet, thereby confirming the message with the non-target but the Cause field is also 128 ( The message of Request accepted) is separated.

In an embodiment, the Cause field of the acknowledgment message that does not include the target field may be 128 (Request accepted) but does not carry the type field of the target data packet. Of course, the Cause field may also be 252 (with data packets that may have been duplicated) Request related to possibly duplicated packets already fulfilled.

In the embodiment of the present application, determining that the confirmation message is included in the confirmation message received by the CDF, the confirmation message is a target confirmation that the first CGF receives the first suspect duplicate packet but does not receive the target data packet. The message makes it very easy to distinguish the target confirmation message from other non-target confirmation messages. If the acknowledgment message does not include the target field, that is, the acknowledgment message is not the target acknowledgment message, sending a second request message for deleting the second suspect duplicate packet to the second CGF, which reduces the The first CGF and the second CGF both output the CDR condition caused by replying to other messages with the same content, that is, the occurrence of the single phenomenon is reduced.

As shown in FIG. 5 and FIG. 6 , the embodiment of the present application provides another method for transmitting a bill, including the following steps:

Step 501: The CDF sends a first suspected duplicate packet to the CGF, where the first suspect duplicate packet includes a sequence number of the target data packet.

Step 502, after the CDF receives the acknowledgment message sent by the first CGF, the CDF determines whether the acknowledgment message includes a target value, and if the acknowledgment message includes the target value, step 503 is performed; If the confirmation message does not include the target value, step 505 is performed.

Step 503: The CDF determines that the confirmation message is a target confirmation message indicating that the first CGF receives the first suspect duplicate packet but does not receive the target data packet.

Step 504: The CDF sends, to the second CGF, a first request message for requesting the second CGF to output a CDR in the second suspicious duplicate packet, where the second suspect duplicate packet includes the target data packet. Serial number and CDR.

Step 505: The CDF sends a second request message for deleting the second suspect duplicate packet to the second CGF.

In an embodiment, the target value of the Cause field of the target acknowledgement message may be 178 (Request related to possibly duplicated packets Accepted), and the Cause of the message that does not include the target value. The field may be 252 (Request related to possibly duplicated packets already fulfilled), or may be 128 (Request accepted). Of course, the specific value of the Cause field of the target confirmation message is not specifically limited herein, as long as it can be confirmed with other non-targets. The message is separated.

In this embodiment, by determining that the acknowledgment message received by the CDF includes the target value, determining that the acknowledgment message is a target confirmation that the first CGF receives the first suspect duplicate packet but does not receive the target data packet. The message makes it very easy to distinguish the target confirmation message from other non-target confirmation messages. If the acknowledgment message does not include the target value, that is, the acknowledgment message is not the target acknowledgment message, the second CGF is sent to the second CGF to delete the second request message of the second suspected duplicate packet, which is reduced because the target is confirmed. The first CGF and the second CGF both output the CDR situation caused by the message replying to other messages with the same content, that is, the occurrence of the single phenomenon is reduced.

As shown in FIG. 7 and FIG. 8 , the embodiment of the present application provides another method for transmitting a bill, including the following steps:

Step 701: The CDF sends a first suspected duplicate packet to the CGF, where the first suspect duplicate packet includes a sequence number of the target data packet.

Step 702: After the CDF receives the confirmation message sent by the first CGF, the CDF determines whether the confirmation message includes a target label, and if the confirmation message includes the target label, step 703 is performed; If the confirmation message does not include the target label, step 705 is performed.

Step 703: The CDF determines that the confirmation message is a target confirmation message indicating that the first CGF receives the first suspect duplicate packet but does not receive the target data packet.

Step 704: The CDF sends, to the second CGF, a first request message for requesting the second CGF to output a CDR in the second suspicious duplicate packet, where the second suspect duplicate packet includes the target data packet. Serial number and CDR.

Step 705: The CDF sends a second request message for deleting the second suspect duplicate packet to the second CGF.

In an embodiment, each step performed before step 701 can carry a unique label. For example, the CDF sends a target data packet to the first CGF. If the CDF does not receive the preset time, The response message sent by the first CGF may carry the tag tag1 in the foregoing process; the CDF sends a second suspicious duplicate packet containing the same sequence number and the same CDR as the target data packet to the second CGF, where the tag tag2 can be carried in the foregoing process. After the first CGF can work normally, the CDF receives the message that the Cause field sent by the first CGF is “Node Alive Request”, and the CDF replies to the first CGF with the Cause field as “Node Alive Response” message. In the foregoing process, The tag tag3 can be carried, and the target confirmation message can also carry the tag tag3. Then, according to the unique tag carried in the received confirmation message, the tag tag3 is matched. If the matching is successful, the message can be determined as the target confirmation message according to the tag.

Alternatively, the target confirmation message may carry a unique label, and the messages in other steps do not carry the label, and the target confirmation message may also be judged.

In an embodiment, when the CDF sends the target data packet to the first CGF, a packet loss phenomenon may occur. According to the GTP protocol, after the packet loss occurs, the CDF retransmits the target data packet to the first CGF. At this time, the retransmitted target packet should be the same as the previous target packet.

In the embodiment of the present application, by determining that the confirmation message received by the CDF includes a unique target label, determining that the confirmation message is that the first CGF receives the first suspect duplicate packet but does not receive the target data packet. The target acknowledgement message makes it very easy to distinguish the target confirmation message from other non-target confirmation messages. If the acknowledgment message does not include the target label, that is, the acknowledgment message is not the target acknowledgment message, send a second request message for deleting the second suspect duplicate packet to the second CGF, which reduces the acknowledgment message with the target The occurrence of the CDR condition of both the first CGF and the second CGF caused by other messages with the same content is reduced, and the occurrence of the single phenomenon is reduced.
