Technical field
The present invention relates to communication network field, particularly GGSN (GGSN) is a kind of gateway GPRS supporting node (GGSN) device and charging method concretely.
Background technology
GPRS (General Packet Radio Service) full name is a GPRS, is a kind of wireless, packet-switched technology based on gsm system, provides end to end, wireless IP connects.Generally, GPRS is the technology that high-speed data is handled, and method is that the form transmission data with " grouping " arrives the user on hand.Though GPRS is the transitional technology that develops to 3G (Third Generation) Moblie as existing GSM network, it all has significant advantage in many aspects.
Owing to used the technology of " grouping ", the misery that user's online can be avoided breaking.In addition, use the method and WAP and different of GPRS online, with the WAP online just as online at home, " dial-up connection " earlier, just and can not use this telephone wire simultaneously after the online, but GPRS is just comparatively superior, downloads data and converses and can carry out simultaneously.Technically, the transmission of sound (i.e. conversation) continues to use GSM, and the transmission of data just can be used GPRS, like this, just the application of mobile phone is risen to a higher level.And development GPRS technology also very " economy ", develop and get final product because need only continue to use existing GSM network.The purposes of GPRS is very extensive, comprises by mobile phone sending and the reception Email, browses on the internet etc.
After having used GPRS, data realize that grouping sends and receives, and this means that simultaneously the user is always online and charge by flow, has reduced cost of serving rapidly.For example the user newly opens a window and reads then in browsing page, has produced the flow of 5kByte, then only receives the money of user 5kB, and the time of reading is free; The user carries out online chat, sends in one hour or has received 6 information, and flow is 1kB, then only receives the money of 1kB, rather than charges by one hour; User's download one first mp3, flow is 4M, online then listening to, then charge is the traffic fee usefulness of 4M, is free when listening to.The advantage of GPRS is that also its data transmission bauds is not that WAP can compare.The transmission speed of present GSM mobile radio communication is a per second 9.6K byte, and the GPRS mobile phone has reached the transmission speed of 56Kbps when releasing, and has reached 115Kbps (this speed is the twice of 56Kmodem ideal rate commonly used) till now especially.
Fig. 1 is the pie graph of Fare Collection System among the prior art GPRS.Mobile switch system (MSC) is to the charging data record (CDR) of GPRS charging arbitrating server transmission based on flow or time, charging gateway (CGF) is to the CDR of GPRS charging arbitrating server transmission based on flow or time, service server will transmit to GPRS charging arbitrating server based on the CDR of incident, by GPRS charging arbitrating server the station message recording is transmitted to charge system.
Serving GPRS Support Node (SGSN) provides and being connected of packet radio controller PCU by Gb Interface, carries out mobile data management, as functions such as user identity identification, encryption, compressions; Link to each other with attaching position register (HLR) by Gr interface, carry out the visit and the access control of customer data base; Link to each other with GGSN (GGSN:GatewayGPRS Supporting Node) by gn interface, functions such as transmission channel that IP is grouped into radio-cell and protocol conversion are provided; Can also provide with the Gc interface of MSC and with the Gd interface of SMS service center (SMSC) to be connected, in order to functions such as the collaborative work of supporting data service and Circuit Service and short message receiving-transmittings.
GGSN is a very important part in the 3G core network, mainly has been the gateway effect, and it can be connected with multiple different data network, as public Packet Data Network (PSPDN) and LAN etc.In the document that has, GGSN is called the GPRS router.GGSN can be the grouping carrying out of the GPRS in GSM net protocol conversion, thereby can be sent to the TCP/IP of far-end or network X.25 to these groupings.
In the etsi GSM12.15 of ETSI (GPRS charging) standard, stipulated five types cdr logging, i.e. S-CDR, M-CDR, G-CDR, S-SMO-CDR, S-SMT-CDR.These five kinds of records are except that G-CDR is produced by GGSN, and other four kinds of records produce by SGSN.S-CDR has reflected the operating position of Radio Resource, and G-CDR has reflected the behaviour in service to the external data network resource, and M-CDR has reflected the expense of system in mobile management.Indicated among the figure that portable terminal access fee usefulness collection point is at SGSN and GGSN.
The grouping of chargeing in the gprs system comprises the charge information that SGSN and GGSN produce, as handling relevant S-CDR and the G-CDR among the GGSN with mobile relevant M-CDR with process among the SGSN.Charging gateway is collected in order to each network element internal metering data to be provided in the system, and carries out the data forwarding work between network and the charge system.
Network needs the take situation of recording user to Internet resources when the user provides service.Chargeing in essence, is according to the operating position of user to Internet resources, according to certain regular computational costs.Miscellaneous service has different charging policy to the occupancy difference of Internet resources, and the charging of same GPRS also has substantial connection with its traffic performance.
Current, many companies are all at development GGSN product, Nokia for example, Huawei, Siemens, Motorola, companies such as Ericsson.Many GGSN products are used as provides privately owned route hardware platform.But do not appear at GGSN and go up the content-based billing function of realization, the Chinese patent in Huawei, application number are 200410000962, about the patent of invention of GGSN structure.In the structure of this invention, it has three kinds of integrated circuit boards, comprises one or more interface boards, one or more service processing board and master control borad.Comprise that also network board is used to all integrated circuit boards in the connected system, master control borad is used to be provided with routing table, management route and user profile, and to each master control borad distribution routing table.Connecting plate is used to receive the grouping of external network, transmits this grouping according to routing table and gives service processing board or master control borad, and service processing board is used for GPRS Tunnel Protocol (GTP) user's function and designs.
Certainly, can the solution network user partly increase the bottleneck problem of being brought in above patent documentation, but still can not solve the user uses the content-based charging of outer net, for example the user uses Packet Data Network (PDN:Packet DataNetwork).By GGSN can only recording user flow, perhaps temporal information, special data in some packet networks, such as e-mail, video, the frequency of utilization of data such as VOIP all is different with user's interest level, so operator need carry out different charges to different data.Along with the development and the maturing of mobile Internet, the business that transmits by wireless medium is just towards diversified development, and particularly after the 3G system arrived, this phenomenon will be more white-hot.Traditional charging needs that enough do not solved mobile Internet based on the charging method of time span or data traffic.
