Abstract
The present invention discloses a method for realizing IP fragment message content charging. The method mainly comprises the following steps of a first message obtaining step, a first charging step and a second charging step, wherein the first message of an IP fragment message is obtained; port number information in the first message of the IP fragment message is extracted and preserved; the first message of the IP fragment message, the subsequent message of the IP fragment message, which is received before the first message of an IP fragment message are charged by charging information comprising the port number; for the subsequent message of the IP fragment message, which is received after the first message of the IP fragment message, the preserved port number information is read; content charging is carried out to the subsequent message of the IP fragment message, which is received after the first message of the IP fragment message by the charging information comprising the port number. The present invention can effectively reduce the calculation of a CPU for processing the charging and a burden of memory read-write in a content charging node, and simultaneously, effectively reduce the memory overhead.
Description
Technical field
The present invention relates to the message content billing technology, in particular, the present invention relates to a kind of method and device of realizing that the IP fragmentation message content charges.
Background technology
Along with the construction of new generation of wireless network, begin to occur the more and more data business, for example downloading business, mail service and streaming media service or the like.Accordingly, carry out content charging based on described data business content and also become the more and more urgent demand of operator.
Generally, content charging is meant content-based charging, particularly be meant the uniform resource locator (URL in protocol type, source destination address, source destination slogan and the message according to the User IP message, Uniform Resoure Locator) etc. the information of aspect is distinguished message, and then charges.Wherein protocol type, source, destination address, source, destination slogan are called as the charging five-tuple, are information the most basic in the content charging.
Described content charging is finished by the content charging node in the network, and described content charging node is a network element of finishing content charging in the network, is used for from information such as user's message extraction charging five-tuples, and message is distinguished charging.Described content charging node is User IP message transparent node on the transmission path in packet domain often, carries out content charging based on packet domain transmission user IP message.
At present, to limit the maximum length of each transmission Frame (by limiting the MTU (MTU of message transmissions in the physical layer of packet switching network, Maximum Transfer Unit), different physical layer MTU is not of uniform size to be caused, the IP message that has so just caused transmitting may be greater than MTU, in order to address this problem, in the prior art, when the IP layer sends message, need to check the MTU of outgoing interface, when finding message, IP packet fragmentation need be divided into the fragment message that meets the MTU size and transmit greater than the local breakout link MTU; In addition for the IP fragmentation message, have only the IP fragmentation message to report for the first time and carry port information in the literary composition, therefore the content charging node also needs to consider the situation of burst IP packet out-ordering simultaneously in the situation of carrying out not only will considering when content charging is handled the User IP message fragment.
Carry port number information owing to have only the IP fragmentation message to report for the first time in the literary composition in the prior art, and IP fragmentation message subsequent packet does not have port number information, for this reason, in existing content charging node network element, adopt all IP fragmentations that at first receive and store same IP message, when receiving all IP fragmentations of described IP message, report for the first time literary composition and all IP fragmentation message subsequent packets of the IP fragmentation message of this IP message recombinated, afterwards the IP message after recombinating is carried out content charging described recombinate successfully.
With reference to figure 1, this figure be prior art to the process chart that the IP fragmentation message carries out content charging, specifically mainly may further comprise the steps:
Step 1 receives and the storing IP fragment message
Step 2, reorganization IP fragmentation message report for the first time literary composition and all IP fragmentation message subsequent packets
Step 3 is obtained reorganization afterwards port number information and other charge information of message;
Step 4 is carried out content charging according to the port number information of obtaining and other charge information to the IP message after recombinating;
To sum up, though above-mentioned prior art can realize the IP fragmentation content of message is chargeed, also there is following shortcoming:
1, reorganization realizes the IP fragmentation content of message is chargeed to the IP fragmentation message because prior art is based on, in process, inevitably to move in a large number internal storage data to the reorganization of IP fragmentation message, therefore increased the weight of to handle in the content charging node central processing unit (CPU that charges, Central ProcessingUnit) computing and memory read-write burden, because the reorganization of IP fragmentation message just can be transmitted after finishing, can produce bigger delay simultaneously.
2, only after reporting for the first time literary composition and all IP fragmentation message subsequent packets, the IP fragmentation message of receiving same IP message just can recombinate owing to the content charging node, therefore need the described IP fragmentation message of buffer memory report for the first time literary composition and all IP fragmentation message subsequent packets, expend a large amount of internal memories.
Summary of the invention
The technical problem that the present invention solves provides a kind of method and device of realizing that the IP fragmentation message content charges, moving a large amount of internal storage datas when avoiding prior art that the IP fragmentation message is carried out content charging causes handling in the content charging node the too frequent and memory read-write burden of the CPU computing of chargeing and weighs, forward delay is big, expends the problem of a large amount of internal memories.
For addressing the above problem, a kind of method that realizes that the IP fragmentation message content charges of the present invention comprises:
Obtain the civilian step of reporting for the first time: obtain the IP fragmentation message literary composition of reporting for the first time;
First charging step: extract and preserve report for the first time port number information in the literary composition of described IP fragmentation message, the IP fragmentation message is reported for the first time literary composition and the IP fragmentation message subsequent packet of the same IP message that receives before, described IP fragmentation message is reported for the first time literary composition and the IP fragmentation message subsequent packet of the same IP message that receives before carries out content charging with the charge information that includes described port number information;
Second charging step: to the report for the first time IP fragmentation message subsequent packet of the same IP message that receives after the literary composition of IP fragmentation message, obtain the port number information of described preservation, and the report for the first time IP fragmentation message subsequent packet of the same IP message that receives after the literary composition of described IP fragmentation message is carried out content charging with the charge information that includes described port number information.
Wherein, the described IP fragmentation message that obtains is reported for the first time and is also comprised before the civilian step:
A, reception IP fragmentation message;
B, judge that whether described IP fragmentation message is the IP fragmentation message literary composition of reporting for the first time, if, carry out and obtain the IP fragmentation message civilian step of reporting for the first time, otherwise, c carried out;
