As can be seen, WiMAX mainly comprises travelling carriage (Mobile Station, be called for short " MS ")/subscriber station (Subscribe Station, abbreviation " SS "), access service network (Access ServiceNetwork, be called for short " ASN ") and connectivity serving network (Connectivity Service Network is called for short " CSN ").

Wherein, ASN is defined as the network function set that the wireless access service is provided for the WiMAX user terminal, and ASN has comprised BS and ASN gateway (ASN GateWay is called for short " ASN-GW ") network element, and an ASN may be shared by a plurality of CSN.

CSN is defined as to the WiMAX user terminal IP is provided Connection Service.

MS/SS is (moving) terminal, and the user uses this terminal to insert the WiMAX network.

The usually said communication of people is the communication between a node and another one node, but increase along with user's request, and the introducing of multiple medium, the user need carry out the communication of one-to-many or multi-to-multi, put the multiple spot transmission mode of (Point to Multipoint is called for short " PTM ") thereby produced.In order to support these patterns to realize the one-to-many multicast broadcasting service on mobile network, simultaneously in order to effectively utilize mobile network resource, prior art has defined the MBS business on the basis of WiMAX.The MBS business is that the point-to-multipoint service of a data source to a plurality of users send data is provided in the mobile network, realizes that Internet resources are shared, raising utilization rate of network resource, the interface resource of especially eating dishes without rice or wine.The MBS of WiMAX definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of following mobile data development undoubtedly.

Two kinds of access modules of MBS business support based on the WiMAX network: single base station is inserted and many base stations are inserted.Under the access module of many base stations, having defined the MBS territory (is MBS Zone, identify with MBS_zoneID) notion, so-called set that the MBS territory is exactly a base station, all base stations in MBS territory are with identical Multicast CID and MBS group Security Association (MBS Group SecurityAssociation, be called for short " MBS GSA "), send the content of same MBS Business Stream, the terminal of having registered the MBS service can receive the MBS business datum by a plurality of base stations in this MBS territory, and when the terminal that is in Idle state moves in interior span base station, MBS territory, need not rebuild connection, can impregnable reception MBS business, realize the seamless switching of MBS business.It is a kind of special case that MBS are inserted in many base stations that MBS is inserted in single base station, and MBS territory scope is defined as in the base station range, and all users of this MBS of reception use same multicast connection identifiers in MBS territory.Prior art does not have detailed description to single base station mode; But under many base station modes, how the base station sends the MBS data, and how terminal receives the MBS data, and how the base station to notify the transmission of the interested MBS data of terminal, and corresponding description is all arranged.

Existing protocol is to the corresponding description of having eated dishes without rice or wine in the MBS system, but how not add the correlation technique of MBS business about terminal.

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 accompanying drawing.

In the present invention, terminal is obtained Multimedia Broadcast Multicast Service MBS service parameter from network side, wherein comprising second of first sign that indication eats dishes without rice or wine to connect and indicating services content identifies, make terminal after receiving this MBS service parameter, can successfully add this MBS business from the MBS business tine of the second sign indication of eating dishes without rice or wine to receive connecting of the first sign indication.

Below first embodiment of the invention is described.First embodiment of the invention relates to the method for terminal adding MBS business in the wireless network, in the present embodiment, initiatively initiate the professional adition process of MBS by terminal, terminal clear and definite its interested MBS business before adding the MBS business is broadcast in which MBS territory (MBS Zone), in the practical operation, terminal can obtain relevant information in the service announcement stage (ServiceAnnounce); Terminal also can know which MBS Zone current BS belongs in the DCD message of current BS broadcasting, if the MBS Zone at the professional place of the interested MBS of terminal is arranged among these MBS Zone of broadcasting, terminal can be initiated the professional adition process of MBS.Specifically as shown in Figure 2.

In step 201, terminal sends the MBS business message DSA-REQ to BS that joins request, and carries MBS Zone sign (MBS Zone ID) and/or the MBS service authentication information at the professional place of MBS that desire adds in this message.

Optionally, this message is the maximum MBS professional ability information of the current support of portability terminal also, be used to inform network side and require this terminal of decision-making whether can normally receive business according to the active service quality (Quality of Service is called for short " QoS ") of MBS business by network side.

In step 202, after BS receives that the MBS business of terminal joins request, whether the message authentication code HMAC/CMAC that at first verifies request message is the validated user of network with verification terminal, be proved to be successful back BS to access service network gateway (Access Service Network GateWay, be called for short " ASN-GW ") send the MBS business message that joins request, as RR-REQ, carried terminal sign MSID, MBS Zone ID and/or MBS service authentication information etc. in this message.Also there are following several situations in this step:

If a) to carry the resource of this MBS business be not pre-configured being used between BS and ASN-GW, and also do not carry out corresponding resource reservation, and the current resource obligate information of holding this MBS business need of BS, then the MBS business that sends to ASN-GW of the BS message that joins request also comprises the resource reservation application, asks to carry out corresponding resource reservation for this MBS business on BS and ASN-GW;

B) not pre-configured if being used between BS and ASN-GW transmitted the bearer path of this MBS business, and also do not create corresponding bearer path, the MBS business that above-mentioned BS sends to ASN-GW if BS holds the bearer path information of the MBS business need message that joins request also comprises bearer path and sets up request, applies for setting up bearer path for transmitting this MBS business on BS and ASN-GW.The realization of the bearer path between BS and ASN-GW can be passed through generic route encapsulation (Generic RouteEncapsulation, abbreviation " GRE "), VLAN (Virtual Local Area Network, abbreviation " VLAN "), multi protocol label exchange (Multi Protocol Label Switching, be called for short " MPLS ") etc. tunneling technique, can be referring to prior art.

C) for the situation of the maximum MBS professional ability information that comprises terminal in the request message, if BS holds the practical capacity requirement of MBS business, i.e. the resource obligate information of MBS business need, then BS judges directly whether this terminal can normally receive this MBS; If the resource obligate information of this MBS business not on the BS, then the MBS business that sends to ASN-GW of the BS message that joins request also comprises the maximum MBS professional ability information of terminal, and request ASN-GW further adjudicates it.

In step 203, after ASN-GW receives that the MBS business from BS joins request, send the request of MBS service authentication to MBS server (MBS Server), whether this terminal of request MBS server authentication has the right of this MBS business of reception.Go back the network access Identifier (Network Access ID, be called for short " NAI ") of portability MBS Zone ID, terminal and/or MBS service authentication information etc. in this request.Also there are following several situations in this step:

If a) functional entity on ASN-GW or the ASN-GW is as service flow authorization person (Service

FloW Authorization, be called for short " SFA ") or MBS Proxy, preserved the authorization message (service authentication result) of MBS business, then ASN-GW need not to send the request of MBS service authentication to MBS Server again, and the MBS business of handling corresponding terminal according to the MBS authorization message of safeguarding joins request and gets final product voluntarily.

B) not pre-configured if being used between ASN-GW and MBS Server carried the resource of this MBS business, and also do not carry out corresponding resource reservation, and ASN-GW holds the resource obligate information of MBS business need, then ASN-GW also comprises the resource reservation application in the MBS service authentication request message that MBS Server sends in this step, applies for corresponding resource reservation for carrying this MBS business on ASN-GW and MBS Server.

C) not pre-configured if being used between ASN-GW and MBS Server transmitted the bearer path of this MBS business, and also do not create corresponding bearer path, and the bearer path information that ASN-GW holds the MBS business need then in this step the MBS service authentication request message that sends to MBS Server of ASN-GW also comprise bearer path and set up request, on ASN-GW and MBS Server, apply for setting up bearer path for transmitting this MBS business.The realization of the bearer path between ASN-GW and MBS Server can be GRE, Level 2 Tunnel Protocol (Layer2 Tunneling Protocol, abbreviation " L2TP "), VLAN, MPLS, IP safety (IP Security, be called for short " IPSec ") wait tunneling technique also but the ip multicast technology, as IGMP, multicast monitoring discovery (Multicast ListenerDiscovery is called for short " MLD ") etc.

D) after ASN-GW receives the maximum MBS professional ability information of terminal, if ASN-GW holds the practical capacity requirement of MBS business, it is resource obligate information, then ASN-GW judges according to terminal maximum capacity information of receiving and the professional desired resource obligate information of this MBS whether this terminal can normally receive this MBS business; Otherwise if the current not resource obligate information of this MBS business of ASN-GW, then interim maximum capacity information of preserving this terminal that receives is so that follow-up further judgement.

In step 204, after MBS Server receives MBS service authentication request from ASN-GW, if self maintained the MBS service authorization information of this terminal, then retrieve MBS service authorization information, search and confirm whether this terminal has the right of enjoying this MBS business, whether in the subscription group of this MBS business, and whether this terminal be authorized to, and obtains the authorization key (MAK) of this MBS business etc. as terminal; If MBS Server does not safeguard corresponding information, can't the independent judgment terminal whether have the ability of this MBS business of enjoyment, then MBS Server also needs to carry out the MBS service authentication to the open an account aaa server request at place of terminal.

If aaa server is received the authentication request from the MBS server, then enter step 205, judge according to user signing contract information and service strategy whether this terminal has the ability of this MBS business of enjoyment, and the service authentication result is returned MBS Server.Simultaneously, optionally, aaa server can also be handed down to MBS Server with the MBS service profile of this terminal, so as MBS Server after process in can directly handle the MBS service authentication request of this terminal that receives.

In step 206, MBS Server returns MBS service authentication result to ASN-GW.Simultaneously, optionally, MBS Server can be handed down to the MBS service authentication information of this terminal certain functional entity among ASN-GW or the ASN-GW, as SFA or MBS Proxy, joins request so that ASN-GW can directly handle the MBS business of this terminal that receives in process from now on.Also there is following situation arbitrarily in this step:

A) optional, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this ASN or the MBSZone without any terminal, then MBS service authentication success back MBSServer can directly upgrade the descending playlist of this MBS business, the sign or the IP address of promptly adding ASN-GW or MBS Proxy in the descending playlist of this MBS business.

B) optional, after the success of MBS service authentication, MBS Server upgrades user's statistical number of this MBS business, so that MBS Server determines actual user's number of this MBS business of current use.

C) optional, if ASN network entity, as BS, ASN-GW, do not know the resource obligate information and/or the bearer path information of MBS business need before, then MBS Server can issue the resource obligate information and/or the bearer path information of this MBS business need simultaneously in this step.

D) the option b of corresponding step 203), if MBS Server receives the resource reservation application from ASN-GW, then judge whether to accept this resource reservation application, and return the result of resource reservation in this step to ASN-GW according to its other resources situation and service strategy.

E) the option c of corresponding step 203), if receiving from the bearer path of ASN-GW, MBS Server sets up request, then MBS Server judges whether to accept this request according to its other resources situation and service strategy, and returns the result that bearer path is set up to ASN-GW in this step.

Optionally, in step 207, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this ASN or the MBS Zone without any terminal, and in step 206, MBS Server does not upgrade descending playlist, then MBS service authentication success back ASN-GW or MBS Proxy register this MBS business to MBS Server, trigger the descending playlist that MBS Sever upgrades this MBS business of its preservation, promptly in the descending playlist of this MBS business, add sign or the IP address of ASN-GW or MBS Proxy; In addition, if do not set up the bearer path between ASN-GW and MBS Server before, or current bearer path information and/or the resource obligate information that does not also issue this MBS business (is not the bearer path information and/or the resource obligate information of this MBS business of ASN-GW/MBS Proxy, can't ask MBS Sever to set up corresponding bearer path and/or reserve corresponding resource), then MBS Server is when responding register requirement, and the bearer path information and/or the resource obligate information of MBS business is issued to ASN-GW/MBS Proxy.

Optionally, in step 208, if it is not pre-configured that being used between BS and ASN-GW transmitted the bearer path and/or the resource reservation of this MBS business, and also do not carry out corresponding resource reservation and/or create corresponding bearer path (promptly in step 202, BS does not send bearer path and sets up request and/or resource reservation request), then ASN-GW sends resource reservation request and/or bearer path is set up request to BS, transmits between BS and ASN-GW and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

Optionally, in step 209, if it is not pre-configured that being used between ASN-GW and MBS Server transmitted the bearer path and/or the resource reservation of this MBS business, and also do not carry out corresponding resource reservation and/or create corresponding bearer path (promptly in step 203, ASN-GW does not send bearer path and sets up request and/or resource reservation request), then in this step, ASN-GW sends resource reservation request and/or bearer path is set up request to MBS Server, transmits between ASN-GW and MBS Server and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

Step 208 and step 209 can be carried out with any sequencing, or parallel expansion.

Then enter step 210, ASN-GW returns the result that the MBS business joins request according to this authenticating result to BS after receiving MBS service authentication result from MBS Sever.Any situation below in this step, also existing:

A) situation a) if ASN-GW receives the resource reservation application of BS, then judges whether to accept this resource reservation application according to network resource status and service strategy in the corresponding step 202.If accept, then carry out corresponding resource reservation.Return the result of resource reservation in this step to BS.

B) situation b in the corresponding step 202), if ASN-GW receives the bearer path request to create of BS, then ASN-GW judges whether to accept this request according to network resource status and service strategy.If accept, then carry out corresponding bearer path and set up.Return the result that bearer path is set up to BS in this step.

C) optional, if at step 203d) in, ASN-GW is the required resource obligate information of this MBS not, can't carry out the judgement of terminal capability, but after step in, as in the step 206, received the MBS service resources obligate information that MBS Server issues, then the MBS service resources obligate information and the step 203d that issue according to MBSServer of ASN-GW) in the maximum MBS professional ability information of terminal preserved judge whether this terminal can normally receive this MBS business.And notify the BS court verdict in this step.

D) optional, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this BS without any terminal, then MBS service authentication success back ASN-GW also need upgrade the descending playlist of this MBS business, promptly adds Base Station Identification BSID in the descending playlist of this MBS business;

E) optional, ASN-GW is after the message of receiving the success of MBS service authentication, can directly upgrade user's statistical number of this MBS business, so that ASN-GW or MBS Proxy correctly add up the number of users of this MBS business of current use in this BS scope, and then also can know the number of users that uses this MBS business in this ASN or the MBS Zone;

F) c in the corresponding step 206), optionally, ASN-GW is handed down to BS with this information in this step in the lump behind the resource obligate information and bearer path information that obtain the MBS business.

Optionally, in step 211, after BS receives replying of adding MBS service request, if the broadcasting scope of MBS business is dynamically to set up, and also receives this MBS business without any terminal in this BS, ASN-GW does not upgrade descending playlist yet, then after the success of MBS service authentication, BS registers this MBS business to ASN-GW, triggers the descending playlist that ASN-GW upgrades this MBS business of its preservation, promptly adds Base Station Identification (BSID) in the descending playlist of this MBS business; After ASN-GW upgrades descending playlist, if the current bearer path of also not setting up between ASN-GW and MBS Server, and ASN-GW does not initiate the registration of this MBS business to MBS Server, then ASN-GW can further register to MBS Server, to upgrade the professional descending playlist of this MBS on the MBS Server, promptly trigger MBS Server adds ASN-GW or MBS Proxy in the descending playlist of this MBS business sign or IP address.

Optionally, in step 212, after ASN-GW receives the register requirement of BS, if transmitting the bearer path and/or the resource reservation of this MBS business, do not set up being used between current ASN-GW and MBS Server, and in step before, ASN-GW does not initiate registration to MBS Sever, then ASN-GW can register this MBS business to MBS Sever in this step, by MBS Sever in response during register requirement, issue corresponding resource obligate information and/or bearer path information, ASN-GW receive after, the response BS register requirement the time, further resource obligate information and/or the bearer path information with this MBS business is issued to BS.

Optionally, in step 213, after BS receives resource obligate information and/or bearer path information, if it is not pre-configured that being used between BS and ASN-GW transmitted the bearer path and/or the resource reservation of this MBS business, and in step before, BS had not sent the request to create of corresponding resource reservation request and/or bearer path, and ASN-GW is the request to create of down distributing resource reservation request and/or bearer path initiatively not, then in this step, BS sends resource reservation request and/or bearer path is set up request to ASN-GW, transmits between BS and ASN-GW and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

Optionally, in step 214, ASN-GW is after this MBS business is carried out corresponding resource reservation and/or set up the respective carrier passage, if it is not pre-configured that being used between ASN-GW and MBS Server transmitted the bearer path and/or the resource reservation of this MBS business, and in step before, also do not carry out corresponding resource reservation and/or create corresponding bearer path, then in this step, ASN-GW sends resource reservation request and/or bearer path is set up request to MBS Server, transmits between ASN-GW and MBS Server and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

Optionally, in step 215, if BS uses link layer multicast mode to transmit this MBS business and this MBS business is not a broadcasting service, then BS also need obtain MBS cryptographic-key used for encrypting group service (MBS

Group Traffic Encryption Key is called for short " MGTEK "), this key is used to generate the traffic encryption key (MTK) of MBS business when eating dishes without rice or wine to transmit.

BS can be by sending the request message of MGTEK key to ASN-GW, request ASN-GW is handed down to BS with the MGTEK of its generation, if ASN-GW is current also is not the professional MGTEK of generation of this MBS, then earlier is the professional MGTEK of generation of this MBS, again the MGTEK that generates is handed down to BS.

If the existing MGTEK of BS or this MGTEK can be generated by BS, then omit this step or trigger BS generation MGTEK in this step.

Then enter step 216, BS sends the professional response message DSA-RSP that adds of MBS to terminal, and the MBS that the carried terminal request adds in this message professional corresponding MBS Zone ID, the connection identifiers CID of eating dishes without rice or wine or the multicast connection identifiers MCID that eats dishes without rice or wine, this CID or MCID go up all MBS content identifications, the sign GSA ID of multicast security alliance of carrying.

Then enter step 217, send the professional acknowledge message DSA-ACk that adds of MBS to BS after terminal is received that MBS is professional and added response message, be used for confirming that this process finishes.

Optionally, when terminal added this MBS business, BS can upgrade user's statistical number of this MBS business in its coverage.

Then enter step 218, after terminal obtains multicast security alliance sign, initiate secret key request message Key Request, be used to ask the key of multi-casting business MGTEK of this MBS business, carry the GSA ID of this MBS business in this request message to BS.

Then enter step 219, after BS receives request, the MGTEK that produces before or obtain is sent to terminal, generate MBS traffic encryption key MTK jointly according to the MAK and the MGTEK that obtain in advance, and receive corresponding M BS business according to the Multimedia Broadcast Multicast Service parameter of obtaining from network side by terminal.In the present embodiment, resource obligate information is meant the descriptor of the resource that classifier parameters and rule, qos parameter and/or compressed parameter and this MBS business of regular equivalent-load are required.Bearer path information is meant the required resource description message of bearer path of bearer path type, bearer path sign and/or this MBS business of bearer path protocol type equivalent-load.The maximum MBS professional ability information of terminal is meant the maximum resource descriptor of the current MBS business of holding that can receive of terminal, as bandwidth, packet loss etc.Typically refer to the capacity of equipment or the current unappropriated resource summation of terminal.The MBS business is meant a service flow (SF) of IEEE802.16d/e definition.

What deserves to be mentioned is that in the present embodiment, if terminal request adds is the MBS multicast service, it is professional and obtain the authorization key (MAK) of this MBS business that then terminal needed to subscribe to earlier this MBS before adding the MBS business.If what terminal request added is the MBS broadcasting service, then in above-mentioned flow process, do not need authentication process, step 201 can not carried the authentication information of MBS to 203 the request message, or this authentication information only is used for this terminal of each node of informing network side and adds this MBS business.This moment, the service authentication of step 204 can omit, and also need not to issue any service authentication result or service authorization information in the step afterwards again.

Second embodiment of the invention relates to the method for terminal adding MBS business in the wireless network, the present embodiment and first execution mode are roughly the same, its difference is, in the first embodiment, terminal is carried MBS Zone ID in adding the MBS service request message, identify the MBS business that needs adding, yet owing to may have a plurality of MBS business among a MBS Zone, in the present embodiment, terminal except carrying MBS Zone ID, also need be carried the MBS content identification MBS Content ID of this MBS business in request message.Therefore, in the present embodiment, need to revise air interface standard IEEE802.16e, make portability MBS Content ID in DSA-REQ message.

Third embodiment of the invention relates to the method for terminal adding MBS business in the wireless network, the present embodiment and second execution mode are roughly the same, its difference is, in second execution mode, the MBS Zone ID of the terminal MBS business that the request of need carrying adds in adding the MBS service request message and concrete MBS Content ID, and present embodiment is improved on the basis of second execution mode, in the present embodiment, the MBS Content ID of MBS business is that the overall situation is unique, in business joins request message, the MBS Content ID that only need carry appointment gets final product, and need not to be concerned about business is broadcast on which MBS Zone.In the present embodiment, need to revise air interface standard IEEE802.16e equally, require portability MBS Content ID in DSA-REQ.

Four embodiment of the invention relates to the method for terminal adding MBS business in the wireless network, in the present embodiment, use the auxiliary process of finishing terminal adding MBS business of 3 layers of multicasting technology, make on the basis of not changing existing air protocol (IEEE802.16d/e), finish the process that terminal adds certain MBS business of appointment.

In the present embodiment, terminal had just obtained corresponding relation and/or this MBS business of MBS Content ID tabulation, ip multicast address and the MBS Content ID of the professional relevant ip multicast address list of its interested MBS, MBS service bearer and has broadcast in which MBSZone before adding the MBS business, in concrete the application, terminal is as obtaining above-mentioned information in the service announcement stage or by other approach.Terminal is before initiating the professional adition process of MBS, if knowing this business broadcasts in which MBS Zone, then also can know which MBS Zone current BS belongs to by the DCD message that detects current BS broadcasting, whether be in the MBSZone at its professional place of interested MBS so that determine current terminal, if not then initiating adition process.Specifically as shown in Figure 3.

In step 301, terminal sends the MBS business and joins request IGMP Join to anchor ASN-GW (Anchor ASN-GW), carries ip multicast address and/or service authentication information that desire adds in this message.This message can be carried on initial service flow (Initial Service FloW is called for short " the ISF ") passage of terminal.

In step 302, after anchor ASN-GW receives that the MBS business of terminal joins request, send the MBS business to MBSProxy and join request, carried terminal sign MSID and terminal desire add in this request IP multicast group address and/or service authentication information.

In step 303, MBS Proxy receives that the MBS business joins request the back to the request of MBS Server transmission MBS service authentication, is used for the right whether this terminal of requests verification has this MBS business of reception.Go back network access Identifier NAI, IP multicast group address and/or the MBSContent ID etc. of portability terminal in this request.Several situations below in this step, also existing:

If a) certain functional entity on the ASN-GW at MBS Proxy or MBS Proxy place, as SFA, preserved the authorization message of MBS business, be that MBS Proxy can carry out the processing of MBS service authentication, then MBS Proxy need not to send the request of MBS service authentication to MBS Server again, and the MBS business of handling corresponding terminal according to the MBS authorization message of safeguarding joins request and gets final product voluntarily.

B) not pre-configured if being used between ASN-GW and MBS Server transmitted the bearer path of this MBS business, and also do not create corresponding bearer path, then MBS Proxy also comprises bearer path foundation request to the MBS service authentication request message of MBS Server transmission, applies for setting up bearer path for transmitting this MBS business on ASN-GW and MBS Server.The realization of the bearer path between ASN-GW and MBS Server can be also ip multicast technology of tunneling techniques such as GRE, L2TP, VLAN, MPLS, IPSec, as IGMP, MLD etc.

In step 304, after MBS Server receives the request of MBS service authentication, if self maintained the MBS service authorization information of terminal, then retrieve MBS service authorization information searching and confirm whether this terminal has the ability of enjoying this MBS business; If MBS Server does not safeguard corresponding authorization message, can not judge whether terminal has the ability of enjoying this MBS business, then MBS Server also needs to carry out the MBS service authentication to the open an account aaa server request at place of terminal.

In step 305, AAA judges according to user signing contract information and service strategy whether this terminal has the ability of this MBS business of enjoyment, and the service authentication result is informed MBS Server.At this moment, optionally, AAA can be simultaneously be handed down to MBS Server with the MBS service authorization information of this terminal, so as MBS Server after process in can directly handle the MBS service authentication request of this terminal that receives.

In step 306, MBS Server returns MBS service authentication result to MBS Proxy.Simultaneously, optionally, MBS Server can be handed down to MBS with the MBS service authorization information of this terminal

Certain functional entity among Proxy or the MBS Proxy place ASN-GW is as SFA, so that MBS

Proxy after process in can directly handle this terminal that receives the MBS business join request.In addition, also may there be following several situation in this step:

A) optional, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this ASN or the MBS Zone, then MBS service authentication success back MBS without any terminal

Server can directly upgrade the descending playlist of this MBS business, promptly adds sign or the IP address of ASN-GW or MBS Proxy in the descending playlist of this MBS business.

B) optional, after the success of MBS service authentication, MBS Server upgrades user's statistical number of this MBS business, so that MBS Server counts actual user's number of this MBS business of use.

C) optional, if do not know the resource obligate information and/or the bearer path information of MBS business need before ASN-GW and/or the MBS Porxy, then MBS Server can issue the resource obligate information and/or the bearer path information of this MBS business need simultaneously in this step.

D) corresponding step 303b), MBS Server judges whether to accept the request to create of bearer path according to its other resources situation and service strategy, and returns the result that bearer path is set up to MBS Proxy in this step.

MBS Proxy then enters step 307 or step 308 after receiving MBS service authentication result from the MBS server, and there are not precedence relationship in step 307 and step 308.

In step 307, MBS Proxy returns the result that this MBS business joins request according to this authenticating result to Anchor ASN-GW.

In step 308, MBS Proxy sends the MBS business according to this authenticating result to BS and joins request, as RR-REQ.Also may there be following several situation in this step:

If a) to carry the resource of this MBS business be not pre-configured being used between BS and ASN-GW, and also do not carry out corresponding resource reservation (promptly BS had not sent the resource reservation application in step before), then MBS Proxy also comprises the resource reservation application in the response message of the terminal adding MBS business that BS sends, and applies for corresponding bearer resource for carrying this MBS business on BS and ASN-GW.

B) not pre-configured if being used between BS and ASN-GW transmitted the bearer path of this MBS business, and also do not create corresponding bearer path (promptly BS had not sent the bearer path request to create in step before), then MBS Proxy also comprises bearer path foundation request in the response message of the terminal adding MBS business that BS sends, and applies for setting up bearer path for transmitting this MBS business on BS and ASN-GW.The realization of the bearer path between BS and ASN-GW can be tunneling techniques such as GRE, VLAN, MPLS.

C) optional, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this BS without any terminal, then MBS service authentication success back MBS Proxy can directly upgrade the descending playlist of this MBS business, promptly adds Base Station Identification BSID in the descending playlist of this MBS business.

D) optional, after the success of MBS service authentication, MBS Proxy upgrades user's statistical number of this MBS business, uses the number of users of this MBS business down so that ASN-GW or MBS Proxy count this BS, and then also can know the number of users that uses this MBS business in ASN or the MBS Zone.

In step 309, BS receive this MBS business join request the response after, if this response is success response, then BS sends the MBS business message DSA-REQ that joins request to terminal, carries in the qos parameter that professional corresponding MBS Zone ID, the connection identifiers CID of eating dishes without rice or wine of MBS that desire adds or the multicast connection identifiers MCID that eats dishes without rice or wine, this CID or MCID go up all MBS content identification MBS ContentID, the sign GSA ID of multicast security alliance of carrying or clean culture Security Association, MBS business one or more in this message.

Optionally, in step 310, if the BS decision uses link layer multicast mode to transmit this MBS business and this MBS business is not a broadcasting service, then BS also need obtain MBS cryptographic-key used for encrypting group service MGTEK, and this key is used to generate the traffic encryption key MTK of MBS business when eating dishes without rice or wine to transmit.

BS can be by sending the request message of MGTEK key to ASN-GW, request ASN-GW is handed down to BS with the MGTEK of its generation, if ASN-GW is current also is not the professional MGTEK of generation of this MBS, then earlier is the professional MGTEK of generation of this MBS, again the MGTEK that generates is handed down to BS.

If the existing MGTEK of BS or this MGTEK can be generated by BS, then omit this step or trigger BS generation MGTEK in this step.

This step there is no fixing sequencing with step 309.

Then enter step 311, after terminal is received DSA-REQ message from BS, judge whether normally to receive this MBS business according to the maximum MBS professional ability that the qos parameter of MBS business requires and terminal itself can bear, if could would preserve corresponding M BS business contexts.Terminal is responded the professional response message DSA-RSP to BS that adds of MBS, carries the result who adds the MBS business in the message.

Optionally, step 312, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this BS without any terminal before, be that BS did not register this MBS business to MBS Proxy, then BS initiates service log-on to MBS Proxy, to upgrade the descending playlist of this MBS business among the ASN-GW, promptly adds Base Station Identification BSID in the descending playlist of this MBS business.

Optionally same, in step 313, after MBS Proxy upgrades the descending playlist of this MBS business among the ASN-GW, if receive this MBS business without any terminal in ASN or the MBS Zone before, be that MBS Proxy did not register this MBS business to MBS Server, then MBS Proxy registers to upgrade the professional descending playlist of this MBS among the MBS Server, the sign or the IP address of promptly adding ASN-GW or MBSProxy in MBS Server in the descending playlist of this MBS business to MBS Server in this step.

Optionally, in this step, do not set up if being used between ASN-GW/MBS Proxy and MBS Server transmitted the bearer path and/or the resource reservation of this MBS business, and do not issued corresponding resource obligate information and/or bearer path information before.Then MBS Server down distributing resource obligate information and/or bearer path in the register requirement of response ASN-GW set up information.After receiving, ASN-GW further when the register requirement of response BS, the resource obligate information and/or the bearer path information of this MBS business is issued to BS.

Optionally, in step 314, if it is not pre-configured that being used between BS and ASN-GW transmitted the bearer path and/or the resource reservation of this MBS business, and in step before, BS does not carry out corresponding resource reservation request and/or creates corresponding bearer path request, ASN-GW or MBSProxy initiatively do not initiate resource reservation request yet and/or create corresponding bearer path request, then in this step, BS sends resource reservation request and/or bearer path is set up request to ASN-GW, transmits between BS and ASN-GW and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

Optionally, in step 315, ASN-GW or MBS Proxy receive from after the resource reservation request of BS and/or the bearer path foundation request, can determine whether to agree to carry out corresponding resource reservation and/or set up corresponding bearer path according to the Internet resources situation.In addition, if this ASN-GW and MBS

Bearer path and/or resource reservation that being used between Server transmitted this MBS business are not pre-configured, and in step before, do not send the request of corresponding resource reservation request and/or establishment respective carrier passage to MBS Sever, then MBS Proxy sends resource reservation request and/or bearer path is set up request to MBS Server, transmits between ASN-GW and MBS Server and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

In step 316, BS sends to MBSProxy or Serving ASN-GW with the MBS business of the terminal response results that joins request.Also may there be following several situation in this step:

If a) at step 308a) in, MBS Proxy also comprises the resource reservation application in the response message of the terminal adding MBS business that BS sends, and then BS judges whether to accept the resource reservation application according to interface-free resources situation and access control strategy in this step.If accept, then carry out corresponding resource reservation.Return the result of resource reservation in this step to MBS Proxy.

B) if at step 308b) in, MBS Proxy also comprises the bearer path request to create in the response message of the terminal adding MBS business that BS sends, then in this step, BS judges whether to accept this bearer path foundation application according to interface-free resources situation and access control strategy.If accept, then carry out corresponding bearer path and set up.Return the result that bearer path is set up to MBS Proxy in this step.

In step 317, after receiving that MBS is professional and add response DSA-RSP message, BS sends the professional acknowledge message DSA-ACK that adds of MBS to terminal, be used for confirming that this process finishes.

In step 318, after terminal obtains multicast security alliance sign, initiate secret key request message Key Request to BS, be used to ask the key of multi-casting business MGTEK of this MBS business, carry the GSA ID of this MBS business in this request message.

In step 319, after BS receives request, the MGTEK that produces before or obtain is sent to terminal, generate MBS traffic encryption key MTK jointly according to the MAK and the MGTEK that obtain in advance, and receive corresponding M BS business according to the Multimedia Broadcast Multicast Service parameter of obtaining from network side by terminal.

What deserves to be mentioned is that in the present embodiment, if terminal request adds is the MBS multicast service, it is professional and obtain the authorization key (MAK) of this MBS business that then terminal needed to subscribe to earlier this MBS before adding the MBS business.If what terminal request added is the MBS broadcasting service, then in above-mentioned flow process, do not need authentication process, step 301 can not carried the authentication information of MBS to 303 the request message, or this authentication information only is used for this terminal of each node of informing network side and adds this MBS business.And the service authentication of step 304 can omit, and also need not to issue any service authentication result or service authorization information in the step afterwards again.

Fifth embodiment of the invention relates to the method for terminal adding MBS business in the wireless network, present embodiment and the 4th execution mode are roughly the same, its difference is, in the 4th execution mode, terminal is before initiating the professional adition process of MBS, obtained the corresponding relation of ip multicast address and MBS Content ID, and in the present embodiment, terminal was not obtained the corresponding relation of ip multicast address and MBS Content ID before adding the MBS business, added in the MBS business procedure its notice terminal in terminal by network side.

Specifically as shown in Figure 4, step 401 is similar to step 317 to step 417 and step 301, does not repeat them here.

In step 418, after MBS Proxy/Serving ASN-GW receives the professional result of adding of the MBS of BS transmission, send the MBS Content ID tabulation of the ip multicast address correspondence of its adding to terminal, this message also professional corresponding MBS Zone ID, the connection identifiers CID of eating dishes without rice or wine of the MBS that adds of portability desire or the multicast connection identifiers MCID that eats dishes without rice or wine, this CID or MCID goes up one or more in all MBS content identification MBS Content ID, the sign GSA ID of multicast security alliance of carrying or the clean culture Security Association.

There is not fixing precedence relationship in this step with step 417.

Step 419 and step 420 and step 318 and step 319 are similar.

Terminal adds the method for MBS business in the sixth embodiment of the invention wireless network, in the present embodiment, the professional adition process of the MBS that initiatively initiates by network side, this process can occur in and preset the setting up in the process of stream after terminal networks, and also can occur in the network side entity requirement and dynamically set up MBS when professional.For multicast service, before the network side requesting terminal adds the MBS business, the authorization key MAK that this terminal needs to subscribe to this MBS business earlier and obtains this MBS business, wherein subscribe message can be included in user's the signatory message.Specifically as shown in Figure 5.

In the present embodiment, network side entity sends the following several possibilities of MBS service creation request existence:

If network the stage at terminal initial, user's signatory message has been issued among the access network entity Anchor ASN-GW, then in step 501, can be by the functional entity among Anchor ASN-GW or the AnchorASN-GW, as SFA, initiate the request of MBS service creation to MBS Proxy, also need carried terminal sign MSID in this request.

Perhaps step 501 ' in, send the request of MBS service creation by MBS Server to MBS Proxy, carry NAI or MSID in this message.In this step, can also comprise following option:

A) optional, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this ASN or the MBSZone without any terminal, then MBS Server can directly upgrade the descending playlist of this MBS business, promptly adds sign or the IP address of ASN-GW or MBS Proxy in the descending playlist of this MBS business.

B) optional, MBS Server can upgrade user's statistical number of this MBS business, so that MBSServer counts actual user's number of this MBS business of current use.

In step 502, if MBS Proxy has just obtained the signatory message of user in the terminal networking authentication stage, then MBS Proxy can directly trigger the request of MBS service creation, perhaps, MBS Proxy further initiates this MBS service creation request to BS after the MBS service creation request of receiving from MBS Sever or Anchor ASN-GW.If use the ip multicast technology when MBS business is transmitted in the IP layer, then MBS Proxy also is responsible for notifying corresponding multicast router (Multicast Route is called for short " MR "), and this terminal is added corresponding multicast group.

In addition, can also comprise following option in this step:

A) optional, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business without any terminal in this BS, then MBS Proxy can directly upgrade the descending playlist of this MBS business before, promptly adds Base Station Identification BSID in the descending playlist of this MBS business.

B) optional, MBS Proxy upgrades user's statistical number of this MBS business, uses the number of users of this MBS business down so that ASN-GW or MBS Proxy count this BS, and then also can know the number of users that uses this MBS business in ASN network or the MBS Zone.

C) not pre-configured if being used between ASN-GW and BS carried the resource of this MBS business, and also do not carry out corresponding resource reservation, then MBS Proxy can also comprise the resource reservation application to the MBS service creation request message that BS sends, and applies for corresponding bearer resource for carrying this MBS business on BS and ASN-GW.

D) not pre-configured if being used between BS and ASN-GW transmitted the bearer path of this MBS business, and also do not create corresponding bearer path, then MBS Proxy also comprises bearer path foundation request to the terminal adding MBS service request message that BS sends, and applies for setting up bearer path for transmitting this MBS business on BS and ASN-GW.The realization of the bearer path between BS and ASN-GW can be tunneling techniques such as GRE, VLAN, MPLS.

Optionally, step 503, if the link layer multicast mode of using BS transmits this MBS business and this MBS business is not a broadcasting service, then BS is to MBS Proxy request MBS business cipher key MGTEK, and this key is used to generate the traffic encryption key MTK of MBS business when eating dishes without rice or wine to transmit.

BS can be by sending the request message of MGTEK key to ASN-GW, request ASN-GW is handed down to BS with the MGTEK of its generation, if ASN-GW is current also is not the professional MGTEK of generation of this MBS, then earlier is the professional MGTEK of generation of this MBS, again the MGTEK that generates is handed down to BS.

If the existing MGTEK of BS or this MGTEK can be generated by BS, then omit this step or trigger BS generation MGTEK in this step.

In step 504, BS sends the MBS business message DSA-REQ that joins request to terminal, carries in the qos parameter that professional corresponding MBS Zone ID, the connection identifiers CID of eating dishes without rice or wine of MBS that desire adds or the multicast connection identifiers MCID that eats dishes without rice or wine, this CID or MCID go up all MBS content identification MBSContent ID, the sign GSA ID of multicast security alliance of carrying or clean culture Security Association, MBS business one or more in this message.

In step 505, after terminal is received DSA-REQ message, judge whether normally to receive this MBS business according to the maximum MBS professional ability that the qos parameter of MBS business requires and terminal itself can bear, if could would preserve corresponding M BS business contexts.Terminal is returned the professional response message DSA-RSP that adds of MBS to BS, carries the result who adds the MBS business in the message.

Optionally, in step 506, if the broadcasting scope of MBS business is dynamically to set up, and also receive this MBS business in this BS without any terminal before, be that BS did not register this MBS business to MBS proxy, then BS initiates registration to upgrade the descending playlist of this MBS business to ASN-GW, promptly adds Base Station Identification BSID in ASN-GW in the descending playlist of this MBS business.

Optionally same, in step 507, after MBS Proxy upgrades the descending playlist of this MBS business among the ASN-GW, if receive this MBS business without any terminal in ASN or the MBS Zone before, be that MBS Proxy did not register this MBS business to MBS Server, then MBS Proxy registers to upgrade the professional descending playlist of this MBS among the MBS Server, the sign or the IP address of promptly adding ASN-GW or MBSProxy in MBS Server in the descending playlist of this MBS business to MBS Server in this step.

Optionally, in this step, do not set up if being used between ASN-GW/MBS Proxy and MBS Server transmitted the bearer path and/or the resource reservation of this MBS business, and do not issued corresponding resource obligate information and/or bearer path information before.Then MBS Server down distributing resource obligate information and/or bearer path in the register requirement of response ASN-GW set up information.After receiving, ASN-GW further when the register requirement of response BS, the resource obligate information and/or the bearer path information of this MBS business is issued to BS.

Optionally, in step 508, if it is not pre-configured that being used between BS and ASN-GW transmitted the bearer path and/or the resource reservation of this MBS business, and also do not carry out corresponding resource reservation and/or create corresponding bearer path, and in step 502, the MBS service creation request message that MBS Proxy sends to BS does not comprise the resource reservation application and/or bearer path is set up request, then in this step, BS sends resource reservation request and/or bearer path is set up request to ASN-GW or MBS Proxy, transmits between BS and ASN-GW and carries out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

Optionally, in step 509, ASN-GW or MBS Proxy receive from after the resource reservation request of BS and/or the bearer path foundation request, can determine whether to agree to carry out corresponding resource reservation and/or set up corresponding bearer path according to the interface-free resources situation.And, if it is not pre-configured that being used between ASN-GW and MBS Server transmitted the bearer path and/or the resource reservation of this MBS business, and also do not carry out corresponding resource reservation and/or create corresponding bearer path, then ASN-GW or MBS Proxy send resource reservation request and/or bearer path is set up request to MBS Server, transmit between ASN-GW and MBS Server and carry out resource reservation and/or set up corresponding bearer path for transmitting this MBS business.

In step 510, after BS receives DSA-RSP message, the MBS business result that joins request is returned MBS Proxy, specifically can pass through response message RR-RSP.In addition, also may there be following several situation in this step:

A) corresponding step 502a), if MBS Proxy does not comprise the resource reservation application to the MBS service creation request message that BS sends, then in this step, BS judges whether to accept this resource reservation application according to interface-free resources situation and access control strategy.If accept, then carry out corresponding resource reservation.And inform the result of ASN-GW resource reservation in this step in the lump.

B) corresponding step 502b), set up request if the MBS service creation request message that MBS Proxy sends to BS comprises bearer path, then in this step, BS judges whether that according to interface-free resources situation and access control strategy the bearer path of accepting applications sets up.If accept, then carry out corresponding bearer path and set up.And inform the result that the ASN-GW bearer path is set up in this step in the lump.

After MBS Proxy is known MBS service creation result, the promoter of notice MBS service creation request.If the initiator of MBS service creation request is Anchor ASN-GW, promptly corresponding step 501 and step 501 ', then entering step 511, MBS Proxy returns the service creation result to Anchor

ASN-GW; If the initiator of MBS service creation request is MBS Server, promptly corresponding step 501 ', then enter step 511 ', MBS Proxy returns the service creation result to MBS Server; If the initiator of MBS service creation request is MBS Proxy, then can omit this step.

In step 512, after receiving that MBS is professional and add response message DSA-RSP, BS sends the professional acknowledge message DSA-ACK that adds of MBS to terminal, be used for confirming that this business adition process finishes.

In step 513, after terminal obtains multicast security alliance sign, initiate secret key request message Key RequeSt to BS, be used to ask the key of multi-casting business MGTEK of this MBS business, carry the GSA ID of this MBS business in this request message.

In step 514, after BS receives request, the MGTEK that produces before or obtain is sent to terminal, generate MBS traffic encryption key MTK jointly according to the MAK and the MGTEK that obtain in advance, and receive corresponding M BS business according to the Multimedia Broadcast Multicast Service parameter of obtaining from network side by terminal.
