Description

The method of chargeing among a kind of mobile network

Technical field

The present invention relates to communication technical field, more specifically, relate to the method for chargeing among a kind of mobile network.

Background technology

(Interworking Wireless Local Area Network I-WLAN) is meant one and third generation partner program (3rdGeneration Partnership Project, 3GPP) wlan network of network interaction to mutual WLAN.I-WLAN is mainly by wlan access network (WLAN Access Network), WLAN IAD (WLAN Access Gateway; WAG), packet data gateway (Packet Date Gateway; PDG), authentication and authorization charging server (Authentication; Authorization and Accounting, AAA Server) and other support nodes formations.Mutual purpose be make the WLAN access technology can with the cooperation of 3GPP core-network infrastructure so that WLAN user can insert the 3GPP packet service through the WLAN access network.

GPRS (General Packet Radio Service; GPRS) access network is by 3GPP Radio Access Network (GSM EDGE Radio Access Network/UMTS Terrestrial Radio Access Network; GERAN/UTRAN), Serving GPRS Support Node (Serving GPRS Support Node; SGSN), Gateway GPRS Support Node (Gateway GPRS Support Node, GGSN) and other support nodes constitute.

When the mobile subscriber has I-WLAN and GPRS access network access capability, need keep business continuance when between two kinds of access networks, switching.The 3GPP normal structure has determined to adopt two stack mobile Internet Protocol sixth versions, and (Dual-Stack Mobile Internet Protocol version 6 is DSMIPv6) as the technical solution that keeps this business continuance.This technical solution is used the anchor point of HA (Home Agent, home agent) as the user mobility management, when the user when GPRS inserts; Set up PDP (the Packet Data Protocol of UE earlier to GGSN; Packet data protocol) context connects, and UE can start the DSMIPv6 protocol stack afterwards, initiates to set up a DSMIPv6 tunnel with HA and is connected; UE is connected to HA through the PDP Context of above-mentioned GPRS, the IP operation that provides through the HA access carrier; When the user when I-WLAN inserts; Set up IPSec (the IP Security of UE earlier to PDG; IP safety) tunnel connects, and UE can start the DSMIPv6 protocol stack afterwards, initiates to set up a DSMIPv6 tunnel with HA and is connected; UE is connected to HA through the tunnel of above-mentioned I-WLAN, the IP operation that provides through the HA access carrier.When UE switched between I-WLAN and GPRS access network, the DSMIPv6 agreement can make its IP address remain unchanged, and realized continuously professional.

Fig. 1 is the Organization Chart of mobility solution between I-WLAN network and the 3GPP network (I-WLAN Mobility).

As UE (User Equipment; Subscriber equipment) in the time of from GPRS accessing group data business, can set up PDP (Packet Data Protocol, packet data protocol) context between UE and the GGSN; Receive when setting up PDP Context at GGSN; GGSN can be according to APN and the configuring condition of self in this request, decision whether need with AAA Server alternately so that the user is carried out authentication, mutual agreement can be Radius or Diameter.GGSN can add up this user's network operating position; The statistics that will comprise user identity and Charging Id (sign charges) is issued charging network element with the form of ticket; At this moment Charging Id is that GGSN generates; It is corresponding with the PDP Context of current activation, and GGSN can produce corresponding a plurality of Charging Id when the user has the PDP Context of a plurality of activation., GGSN can comprise current radio access technology types of user (RAT Type, Radio Access Technology Type) and Charging Id in sending to the user authentication request of AAA Server.

When UE is professional from the I-WLAN accessing group data; Can set up ipsec tunnel between UE and the PDG; Receive when setting up tunneled requests that at PDG PDG can be according to W-APN (WLAN-APN, wireless local area network AP N) and the configuring condition of self in this request; Decision whether need with AAA Server alternately so that the user is carried out authentication, mutual agreement can be Radius or Diameter.PDG can add up this user's network operating position; The statistics that will comprise user identity and Charging Id (sign charges) is issued charging network element with the form of ticket; At this moment Charging Id is that PDG generates; It is corresponding with current ipsec tunnel, and PDG can produce corresponding a plurality of Charging Id when the user has a plurality of ipsec tunnel., PDG can comprise current radio access technology types of user (RAT Type, Radio Access Technology Type) and Charging Id in sending to the user authentication request of AAA Server.

During I-WLAN Mobility framework in using Fig. 1; Using the DSMIPv6 agreement to set up the tunnel between UE and the HA connects; The IP operation that UE provides through the HA access carrier, this moment, HA can provide the charge information that comprises the user network operating position, issued charging network element through AAA Server.AAA Server only collects the charge information of HA, does not collect the charge information of PDG or GGSN.Since charge system need be current according to the user the access technology type: GPRS (comprising GERAN and UTRAN) or WLAN; Adopt different rate accountings, therefore in the charge information that charging network element is received, need comprise the current radio access technology types of user (RAT Type).But because HA is connected the RAT Type information that does not provide current with the DSMIPv6 tunnel that UE sets up; So offering in the charge information of AAA Server, HA do not comprise RAT Type; Thereby the charge information that charge system can't be collected from HA combines charge with corresponding charging rate, can not realize effective charging.

And to realize effective charging; Because GGSN or PDG also can charge to this user; Therefore when the user when GPRS inserts; GGSN and HA are charging points, and the charge information that AAA Server is responsible for transmitting the HA generation is to charging network element, and charging network element will be received charge information from GGSN and AAA Server simultaneously; When the user when I-WLAN inserts,, PDG and HA are charging points, AAAServer is responsible for transmitting the charge information that HA produces and gives charging network element, charging network element will be received charge information from PDG and AAA Server simultaneously.At this moment need above-mentioned charge information be associated, so that unified charge information to be provided.In above-mentioned charge information, all include user totem information; Like user identity; IMSI (International Mobile Subscriber Identity for example; IMSI International Mobile Subscriber Identity), but only can only the charge information of user class be associated, when inserting from GPRS, UE exist a plurality of PDP Contexts or UE to insert when having a plurality of ipsec tunnel from I-WLAN according to IMSI; Maybe not every PDP Context or ipsec tunnel being connected between UE and the HA all is provided, at this moment just need to provide between UE and the HA in the middle of the charge information and the charge information that HA provides of the PDP Context that connects or ipsec tunnel related.

In Fig. 1 framework, the customer charging information that HA gathers do not comprise the current radio access technology types of user and and the charge information gathered of other charging points between complete related information.If charging network element is received the charge information of being sent by AAA Server by the HA collection; It can't take corresponding rate accounting according to the current radio access technology types of user; Thereby can't realize effective charging; Further, also can't be correctly that the charge information of itself and other charging points is related.
