Abstract
The key point of the invention is that mobile data service platform (MDSP) is added to cell multimedia broadcast (CMB) system. When user equipment (UE) establishes connection to access network and core network, after wireless network controller (RNC) in the access network obtains user id of UE, UE sends program id to RNC through description message. Through request message of authentication, RNC sends program id and user id to MDSP for carrying out authentication, and receives returned result of authentication. RNC determines whether authentication is successful or not; if yes, then RNC sends CMB service data to UE; otherwise, ending CMB service. Moreover, MDSP can carry out charging CMB service of user. When authentication is successful, RNC informs MDSP to carry out charge and to send CMB service data to UE.
Description
Technical field

Along with the development of mobile communication technology, operator can provide multimedia short message service, packet-switched domain (PS) video stream traffic, visual telephone service, multimedia broadcast multi-broadcasting business etc. to the mobile subscriber by universal mobile telecommunications system (UMTS).Wherein, multimedia short message service, PS domain video stream business and visual telephone service need wireless network that the transmission bearer of point-to-point is provided, and multimedia broadcast multi-broadcasting business then needs wireless network that the transmission bearer that a little arrives multiple spot is provided.
In order to realize multimedia broadcast multi-broadcasting business, a kind of broadcasting service that is carried on the Common Control Physical Channel (SCCPCH) has been proposed at present, i.e. cell multimedia broadcast (CMB, Cell MultimediaBroadcast).The CMB business is based on third generation co-operative project (3GPP) R4/R5 version and puts forward, its key is to increase a multimedia administration center (MMC) server, MMC and service universal grouping wireless business supporting node (SGSN, Serving GPRS Support Node) links to each other, be used to preserve broadcast program data, and be responsible for to radio network controller (RNC, Radio Network Controller, RNC) transmission broadcast program data.
Fig. 1 has shown the system group network structure chart of implementing the CMB scheme.As shown in Figure 1, the CMB system comprises:
Subscriber equipment (UE, User Equipment) is used for initiating the CMB business request information and receiving the CMB business datum by air interface.
RNC is used to receive the CMB business request information of UE, and the CMB business request information of UE is sent to SGSN and receives the CMB business datum that sends from SGSN, and the CMB business datum is sent to UE.
SGSN is used to receive the CMB business datum that MMC sends, and is transmitted to RNC.
MMC is used to preserve the CMB business datum, and the CMB business datum is sent to SGSN.
In the CMB system, MMC constantly sends to SGSN with the CMB business datum; SGSN constantly is transmitted to RNC with the CMB business datum that receives; And RNC only sends to the CMB business datum mobile subscriber of CMB service request.
When certain mobile subscriber will watch broadcast program, CMB realizes that the basic procedure of multicast service is: UE sent the CMB business request information by RNC to SGSN; SGSN receives after the CMB business request information, sends the CMB service response message to RNC; Then, RNC sends the CMB business datum to UE, realizes the CMB business.
CMB has broken through the mode that traditional point-to-point is watched broadcast program, no longer adopting dedicated channel is some mobile subscriber's service manner, but adopts the mode of broadcasting in a sub-district, makes a plurality of mobile subscribers can watch broadcast program, conserve network resources has reduced the customer service expense.In general, in the sub-district, adopt the mode of broadcasting to watch broadcast program, also can be called multicast service usually; Adopt the CMB scheme to realize that the mobile subscriber watches that broadcast program is commonly referred to the CMB business, the data of its broadcast program are commonly referred to the CMB business datum.
In actual applications, need carry out authentication, and the CMB scheme there is not to propose the mobile subscriber is carried out the method for authentication to the mobile subscriber.Though the R6 version of 3GPP has related to the method for authenticating about multimedia broadcast/group broadcast service, it is the method for core that this method is based on SGSN, and CMB is to be the method for core with RNC, so can't be applied directly in the CMB business.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Basic thought of the present invention is: RNC sends to MDSP with program identification and user ID and carries out authentication, and judges whether success of authentication according to authenticating result, if then send the CMB business datum to UE; Otherwise, directly finish the CMB business.
Fig. 2 has shown the present invention program's flow chart.Shown in 2, the present invention program realizes that the CMB business may further comprise the steps:
Step 201:UE sends to RNC with program identification;
Step 202:RNC sends to MDSP with program identification and user ID;
Step 203:MDSP carries out authentication according to program identification and user ID, and returns authenticating result to RNC;
Step 204:RNC judges according to authenticating result whether authentication is successful, if then RNC sends the CMB business datum to UE; Otherwise, directly finish the CMB business;
Among the present invention, UE is before carrying out the CMB program, need connect with Access Network and core net (CN), wherein, Access Network is universal mobile telecommunications system grounding wireless access network (UTRAN), the method that connects is: UE earlier with UTRAN in RNC between set up Radio Resource and control (RRC) and be connected, again and set up RAB (RAB) between the SGSN among the CN and be used to carry the CMB business.In general, in the process that UE and Access Network and core net connect, RNC can obtain the user ID of UE.Finish after the work that connects as UE, just can carry out the CMB business.
Method embodiment
Fig. 3 is the message flow schematic diagram that application the present invention program's embodiment realizes the CMB business.In the present embodiment, UE connects with UTRAN and CN, and RNC has obtained user ID in the process that connects.In the present embodiment, UE will be successfully by the authentication of MDSP, and in the process of watching the CMB program, charge in real time, when the CMB service ending, initiatively initiate to discharge the process of CMB business by UE.
As shown in Figure 3, present embodiment realizes that the method for CMB business may further comprise the steps:
Step 301:UE sends the describing message of the real-time streaming protocol that carries program identification to RNC.
In actual applications, when carrying out the transmission of real-time streaming protocol message between UE and the RNC, the connection that needs elder generation set up transmission control protocol between UE and RNC could send real-time streaming protocol message then.Wherein, the describing message of real-time streaming protocol generally can abbreviate describing message as, and in like manner, the success response message of the real-time streaming protocol of the following stated, the playing request message of real-time streaming protocol etc. can abbreviate success response message, playing request message etc. as.
Step 302:RNC sends the subscription authentication request message that carries program identification and user ID to MDSP.
In actual applications, user ID can be international mobile subscriber identity (IMSI), also can be mobile user comprehensive service digital net number (MSISDN).The method that RNC obtains IMSI is: setting up in the process of UE and UTRAN and CN, SGSN will send the public ID message that carries IMSI to RNC, and RNC just can obtain IMSI from this message.The method that RNC obtains MSISDN is: setting up in the process of UE and Access Network and core net, SGSN preserves Mobile Subscriber International ISDN Number, when RNC sends when obtaining the request message of mobile subscriber MSISDN to SGSN, SGSN just can return the response message that obtains mobile subscriber MSISDN that carries MSISDN to RNC, and RNC just can obtain MSISDN from this message.
Step 303:MDSP carries out authentication according to program identification and user ID, and the result of successful authentication is sent to RNC by the subscription authentication response message.
In actual applications, the method for MDSP authentication can for: MDSP inquires about local data base according to user ID, judges whether this user has the right to watch the CMB program of this program identification correspondence, if then be judged as authentication success; Otherwise, be judged as failed authentication.
Step 304～step 305:RNC judges authentication success, then sends the success response message of real-time streaming protocol to UE, and UE sends the playing request message of real-time streaming protocol again to RNC.
In actual applications, if failed authentication, expression UE does not have the CMB program that authority is watched the program identification correspondence, and RNC will send the failure response message of real-time streaming protocol to UE so, and discharge the CMB business, and UE is being connected of dismounting and UTRAN and CN again.
Step 306～step 307:RNC sends user's charging request message to MDSP, and MDSP carries out resource reservation and charges, and again the resource reservation situation is notified to RNC by user's charge response message.
In actual applications, the user may be the prepaid user, also may be the postpaid service user.If the user is the prepaid user, then MDSP can carry out resource reservation according to user's current residual rate situation; And if the user is the postpaid service user, then MDSP can directly carry out resource reservation, and then, MDSP just can charge according to the situation of resource reservation.Wherein, resource reservation can be that time resource is reserved, and also can be the flow resource reservation.Time resource is reserved as: MDSP after receiving user's request of chargeing at every turn, all be that RNC stipulates a data unit to the CMB business datum that UE sends, this data cell is standard with time, such as: MDSP regulation RNC can only send 5 minutes CMB program data to UE at every turn; The implication that flow resource reservation and time resource are reserved is basic identical, but it is with the standard of flow as data unit size, such as: MDSP can stipulate that RNC can only send the CMB program data of 1M to UE at every turn.
Step 308:RNC sends the success response message of real-time streaming protocol to UE, and writes down the zero-time of CMB business.
Step 309～step 311:RNC sends the CMB business datum according to the resource reservation situation to UE, and RNC sends user's charging request message to MDSP, and MDSP carries out resource reservation and charges, and again the resource reservation situation is notified to RNC by user's charge response message.
In actual applications, the user watches that the data volume of CMB program may be greater than RNC according to the data volume of resource reservation situation to UE transmission CMB business datum, and the CMB system is with repeated execution of steps 309～step 311.During each repeating step 309～step 311, MDSP can add up charging value at every turn circulating, as up-to-date charging value.
Step 312:UE sends the release request message of real-time streaming protocol to RNC.
In the present embodiment, the user has watched program or has initiatively withdrawed from the CMB business midway at program.But in actual applications, if the user is the prepaid user, and the residue rate have been when deficiency has been watched the CMB program, and RNC just is notified to UE with the information of rate deficiency earlier, and then execution in step 312～step 315.
Step 313:RNC writes down the concluding time of CMB business, and sends the user's charging request message that carries zero-time and concluding time to MDSP.
Step 314:MDSP record start time and concluding time, finish this CMB service billing, and return user's charge response message to RNC.
Step 315:RNC sends real-time streaming protocol to UE and discharges response message, and UE dismounting and Access Network and core net is connected then.
Implementing the present invention program can carry out authentication and charging to the user who carries out the CMB business, realizes having the CMB business of authentication and billing function.Need to prove that what the present invention relates to is method after UE and UTRAN and CN connect,, also need in advance and the CMB program is contracted, promptly have only signatory user just can carry out the CMB business if the user will successfully realize the CMB business.
In actual applications, RNC also can directly send the CMB business datum to UE, and not need to charge after the subscription authentication success, and this situation goes for the user that the user charges for monthly payment.
At the method that realizes cell multimedia broadcasting service, the present invention also proposes a kind of system that realizes cell multimedia broadcasting service, this system comprises at least: UE, RNC and MMC, its basic thought increase a MDSP in this system, be used for the authentication process to the user.In actual applications, MDSP can also be used for the processing of chargeing.
Fig. 4 is the networking diagram that present embodiment is realized the system of cell multimedia broadcasting service.In the present embodiment, MDSP both can carry out authentication to the user, can charge to the user again, and present embodiment comprises: UE401, RNC402, SGSN403, MMC404 and MDSP405.Wherein, MMC404 is responsible for the CMB business datum is sent to RNC402 by SGSN403.
When the user carried out the CMB business, UE401 sent to RNC402 with program identification; RNC402 sends to SGSN403 with program identification and user ID, by SGSN403 program identification and user ID is sent to MDSP405 again; MDSP405 carries out authentication according to program identification and user ID, and authenticating result is sent to SGSN403, is transmitted to RNC402 by SGSN403; RNC402 judges according to authenticating result whether authentication is successful, if, then success response message is sent to UE401, receive the playing request message that UE401 sends again, and user's charging information sent to SGSN403, SGSN403 is transmitted to MDSP405 with user's charging information, carry out resource reservation and charging by MDSP405, MDSP405 returns to SGSN403 with the situation of resource reservation by charge response message, SGSN403 sends to RNC402 with success response message again, then, RNC402 sends the CMB business datum according to the resource reservation situation to UE401 again; Otherwise, finish the CMB business.
In actual applications, when RNC402 according to the resource reservation situation after UE401 sends the CMB business datum, if the CMB business does not also finish, then RNC402 then sends user's charging message by SGSN403 to MDSP405 again, carry out resource reservation and charging by MDSP405 again, MDSP405 returns to SGSN403 with the situation of resource reservation by charge response message, RNC402 sends the CMB business datum according to the resource reservation situation to UE401 more then, RNC402 this process that constantly circulates is up to finishing the CMB business.
In actual applications, MDSP405 can also directly be connected with RNC402, and then the message between MDSP405 and the RNC402 just need not to transmit by SGSN403.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
