Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Fig. 2 is the flow chart of the MBMS according to the present invention method of charging by flow.The method that MBMS of the present invention charges by flow is when the terminal use adds the multimedia multicast group, business side need terminal carry out traffic statistics and the indicia band returned to terminal.When the multicast content that terminal is carried out traffic statistics to needs is watched, regularly preserve the information such as sign of watching the flow of content, the time of watching and content, preservation regularly can be avoided under unexpected shutdown of terminal or the unreachable situation, the information of watching of terminal record can be at utmost near the actual information of watching of terminal, to avoid under the fortuitous event, in time do not preserve the information of watching of watching information and causing and in time do not note.
When terminal was initiated to leave multicast group, terminal carried terminal in Leaving message was watched information such as multimedia flow.Because terminal when watching multicast service, is not to be initiated by UE because the existence of other abnormal conditions causes Leaving message, but by RNC, SGSN, or GGSN initiates.So when once watching same multicast service, might not guarantee that the information such as flow of watching can return to BM-SC smoothly, passed mark back so need carry out flow to these contents that has returned flow information, the flow that has transmitted just no longer passes, there is not the multimedia multicast content of the flow information of passback for those, can treat that next terminal initiatively takes back during Leaving, when having the network abnormal conditions, the flow information that may have the multimedia multicast service of repeatedly watching is taken back to BM-SC when a terminal active Leaving.Because each terminal initiatively during Leaving, all will return the flow that did not return, if once Hui Chuan flow information is excessive, then waits until returning next time.When BM-SC receives the Leaving request, if carry the flow information of watching of multimedia multicast content in the message, then giving CDF (charging data function entity), when OCS (Online Charging System) sends request, on the flow information band, if what comprise in the flow information is not the information of watching of this content of multimedia, then in charge information, increase the professional Id that replenishes, and flow information.
As shown in Figure 2, this method specifically may further comprise the steps:
Step S202, terminal will require the mark of terminal return flow to send to terminal by business side in the process that adds the multimedia multicast group;
Step S204, the terminal storage mark, and when receiving the multicast service with mark, multicast service is carried out traffic statistics and stores flow information;
Step S206 when terminal is left the multimedia multicast group, sends to business side with flow information; And
Step S208, business side is after receiving flow information, and to charge system transmitted traffic information, charge system is chargeed by flow information.
Wherein, step S202 can comprise following processing: terminal is carried mark in by the Authentication Response of issuing GGSN adding business side; GGSN carries mark in issuing the notification message of SGSN; And SGSN carries mark in the message of the request MBMS context activation of issuing terminal.
In step S204, flow information corresponds respectively to the ID of each content of multimedia of watching.
This step S204 comprises following processing: when terminal receives multimedia multicast service, the business of the multicast group that requires return flow is carried out the mark of traffic statistics and return flow information, and for the content of multimedia that carries out traffic statistics and return label, terminal when watching at every turn, write down the ID and the flow of each content of multimedia of watching, and the information such as time period of watching; Information watched in the terminal record, must be the periodic logging flow information, for example when watching content of multimedia, write down flow information, and caused flow information to have little time to write down to avoid terminal sudden power or other reason in per 2 minutes; And, after terminal has been watched the content of multimedia that needs return flow information, the information of watching of content of multimedia is sent to memory function module in the terminal configuration memory function module.
As shown in Figure 3, specifically illustrated that terminal adds the multicast group flow process in the method that MBMS according to the present invention charges by flow, though it is identical with agreement that this flow process surface is seen, carried out transformation but be actually, when the terminal decision will add a multicast group (signatory this multicast service of this terminal), UE (subscriber equipment just is meant terminal) activates the PDP Context of a general purpose, specifically comprises following improvement flow process:
S302, an IGMP (IPv4) or MLD (Ipv6) Join message are come specific multicast MBMS bearer service of mark UE reception interested on default PDP Context, and this bearer service is discerned by IP multicast address;
S304, GGSN sends a MBMS authentication request, seek to receive the authentication of data for the UE that activates, in the authentication response message of BM-SC, carry need return flow mark (for whether charging by flow, but the CAMEL-Subscription-Information of inquiry terminal, that is to say can contract by terminal charges by flow), and if MBMS Authentication Response indication UE is not authorized to receive the MBMS data, then this process stops, and has no longer included other interacting message;
S306, GGSN sends MBMS notice request (IP multicast address, an APN (Access Point Name), Linked NSAPI (MBMS Network node point identification) and the mark that whether needs charge on traffic) to SGSN, SGSN sends a MBMS push-notification-answer message to GGSN, whether the Cause indication MBMS context activation in the response message goes on, Cause indication operation in receiving corresponding message is unsuccessful, and then GGSN will no longer send any MBMS request message, and flow process finishes;
S308, SGSN sends MBMS context activation request message to UE, ask it to activate a MBMS UE context, in this request message, comprise IP multicast address, APN, Linked NSAPI, TI (transmission sign) and the mark that whether needs charge on traffic;
S310, UE creates a MBMS UE context and sends the MBMS context request (IP multicast address (IP multicast address), APN, MBMS_NSAPI, MBMS bearer capabilities (MBMS bearing capacity)) of an activation to SGSN, it doesn't matter for the activation of back and the present invention, so omit, no longer introduce;
S312, UE carries out traffic statistics to this multicast service according to the needs of the mark of return flow, with carry out flow storage, because the multicast service that UE need return may exist a plurality of, so need to realize the traffic statistics respectively of a plurality of multicast services, preserve management for whether having returned also to mark;
S314, BM-SC began message through GGSN, SGSN and RAN to the UE initiation session before sending multicast service, because conversation procedure and the present invention are irrelevant, so only simply show, detailed process slightly;
S316, BM-SC sends multimedia multicast service to UE; And
S318, UE regularly refresh the flow information of watching the multimedia multicast content and are saved in the terminal storage when receiving the multimedia multicast service content.
In addition, in the method that this MBMS charges by flow, terminal writes down flow information according to predetermined space.
In step S206, when terminal is initiatively left the multimedia multicast group, flow information is sent to business side, and when terminal is forced to leave, terminal sends to business side with the flow information of this time next time when initiatively leaving.
In the method that this MBMS charges by flow, terminal is after sending to business side with flow information, the flow information that has sent is carried out passback tag, and in the time once can not sending all flow informations fully, will not be carried out the flow information of passback tag and wait until and send next time.
This step S206 specifically comprises following processing: if the Leaving process is not to be initiated by UE, but leave process by the pressure terminal that other network element is initiated, then this need be carried at flow information that the multimedia broadcast contents in the Leaving request watches then by next terminal initiatively the process of Leaving take back; And because after terminal adding group, more than one of the content of multimedia possibility that receives, so each terminal is Leaving initiatively, the content of multimedia flow information of taking out from terminal returns to BM-SC by Leaving, these contents that returned flow information are carried out flow passed mark back, the flow that has transmitted just no longer passes, in addition, because each terminal is initiatively during Leaving, all to the flow that did not return be returned, if once Hui Chuan flow information is excessive, then wait until passback next time.
As shown in Figure 4 and Figure 5, specifically illustrate terminal and left the flow chart that multicast group is transformed the flow process of standard, wherein, Fig. 4 is that terminal is left the schematic diagram that multicast group is carried out the online charging flow process in the MBMS according to the present invention method of charging by flow, and Fig. 5 is that terminal is left the schematic diagram that multicast group is carried out the offline charging flow process in the MBMS according to the present invention method of charging by flow.Below in conjunction with Fig. 4 and Fig. 5 this flow process is described in detail.
As shown in Figure 4, specifically comprise following flow process:
S402, (UE is when generating leave group message sending IGMP (IPV4) or MLD (IPV6) leave group message on default PDP (packet data protocol) context for UE, from UE, obtain the management information of this multimedia multicast service, watch flow information if find that the relevant content of this multicast service need be returned, and do not return inflow-rate of water turbine information, then carrying this multimedia multicast service in leave group message watches, but watch that content does not also have the mark and the flow information of those contents of return flow information), leave specific multicast service and discern by IP multicast address;
S404, GGSN send the multicast Indication message to BM-SC agency and transfer function, by it message forwarding are arrived BM-SC member's function, and indication UE leaves the multicast service by IP multicast address identification, and this process realizes by the Gmb mouth;
S406, BM-SC sends charging request message to CDF, if carry the flow information of watching content in Leaving message, then these information is carried in the request of charging and brings CDF, and then, CDF sends the response of chargeing to BM-SC;
S408, leave indication in case receive, BM-SC member's functional verification meets the IP multicast address of an effective MBMS bearer service and sends a UE removal request (IP multicast address, APN and IMS (IP multimedia subsystem, IMS)) gives GGSN, this message trigger is left indication, sends the UE removal request to GGSN simultaneously;
S410, in the UE removal request that receives for some reason, GGSN initiates a MBMS UE context deactivation request message, and GGSN is given in SGSN initiation MBMS context deactivation response; And
S412, in case receive MBMS UE context deactivation request or other reasons, SGSN sends a deactivation MBMS context request (TI) to UE, TI is used for discerning MBMS UE context, and delete in UE, and UE deletes the MBMSUE context and the deactivation of transmission MBMS context responds SGSN.
Should be appreciated that above-mentioned flow process is not very complete Leaving, only described the flow process very relevant with method of the present invention herein, all the other flow processs are not all simply stated.
