Abstract
The invention discloses a method for authenticating multicast broadcast service which comprises the following steps: a mobile terminal initiates an application message for multicast broadcast service to a base station which transmits a request message for service authentication to a authenticator; the authenticator acquires a mark of a multicast broadcast service supplier or an address of a multicast broadcast service controller from the request message for the service authentication, or acquires the mark of the multicast broadcast service supplier or the address of the multicast broadcast service controller from the mobile terminal, and the authenticator acquires the address of the multicast broadcast service controller through the mark of the multicast broadcast service supplier; and the authenticator initiates an authentication request to the multicast broadcast service controller indicated by the address of the multicast broadcast service controller. By adopting the method of the invention, a highly efficient authentication of MCBCS registration process actively initiated by the user is realized and service experience of the user is improved.
Description
Technical field
The present invention relates to the communications field; Relate more specifically to a kind of WiMAX (WorldwideInteroperability for Microwave Access; The global intercommunication microwave access) implementation method of network MCBCS (Multicast and Broadcast Services, multimedia broadcast/multicast service) authentication.
Background technology
WiMAX MCBCS is the system that realizes multimedia broadcast/multicast service, is a kind of operation system that business is offered simultaneously a plurality of users.Through MCBCS, the Virtual network operator of WiMAX can provide a large number of services for the user.
As shown in Figure 1, be that typical MCBCS business provides network structure, form by CSN (Connectivity Service Network, connectivity serving network) and ASN (Access ServiceNetwork, access service network).Comprise the MCBCS controller in the CSN network, content supplier, service statement (this function is generally realized by the MCBCS controller) and the authentication of MCBCS business program are provided, authorize and accounting server AAA functional entitys such as (Authentication, Authorization, Accounting).
And the basic network element of the WiMAX in the ASN network comprises access gateway AG W, base station BS and mobile station MS (being portable terminal), all need support carrying out of multimedia broadcast/multicast service.
The user can obtain the MCBCS business information through service statement among the connectivity serving network CSN, and carries out service log-on according to the interest of oneself, and perhaps application is used.
Under the prior art standard, the user can carry out professional registration through several method.Comprise:
The user uses IGMP Join (adding of Internet igmpinternet) to carry out the business adding;
The user is through DSA (the Dynamic Service Addition of IEEE802.16 series standard definition; Business Stream adds)/DSC (Dynamic Service Change; The dynamic service flow modification) (being abbreviated as DSx, i.e. dynamic service increase/modification message) carried out professional registration work.
In the present standard, defined the relevant parameter of the professional MBS (Multicast/Broadcast Services) of relevant several multicast/broadcast, having comprised:
1) MBS is professional, and the explanation of MBS Service:MBS class of business shows it is to support single BS, the business that still many BS insert;
2) MBS area identification, MBS Zone ID: the MBS area identification that many BS insert is supported in indication;
3) MBS content ID, MBS contents ID: be the value of one 2 byte, be used to identify the professional content of MBS.When using logical channel (logical channel) ID, content ID is corresponding with logical channel ID.
As shown in Figure 2, the method for multicast broadcasting service authentication may further comprise the steps:
Step 201, the user obtains the MCBCS business information through service statement or other approach;
Step 202, MS carries out business application/activation through sending DSx message to BS, in this message, carries the content ID (MBS content ID) of multicast broadcast service.Be that the user carries out the work of setting up of service channel through DSx message, initiatively initiate the professional application of its interested MCBCS;
Step 203, BS initiates professional application authentication to the AGW/ authentication device after receiving the professional solicitation message of DSx; Business to user and user request is carried out authentication, wherein, is to guarantee that this user is the validated user of network to user's authentication; And be to guarantee that this user is professional validated user to the authentication of business.
In the concrete implementation procedure, BS sends to MCBCS business authentication demand the authentication device (Anchor Authenticator) of ASN.And to user's authentication, in general, authentication in user's initial access process (this can discern through the user Context among the BS); But because DSx message is the message of media interviews control MAC (Media Access Control) layer, the user possibly not carry out just sending this message under the situation of network access authentication.Generally speaking, not through under the situation of access authentication, authentication device should be refused this message the user, though not clearly definition in the existing standard.
Step 204, optional, authentication device obtains the MCBCS controller address;
Authentication device can obtain this address through manual configuration, also can be through obtaining the MCBCS controller address from AAA alternately with AAA.
Suppose that the user is in its home network; And know that this MCBCS professional (by MBS content ID sign) is provided by one in the home network unique MCBCS service provider; The AAA place disposes service provider's corresponding information, and authentication device just can be known this MCBCS controller address from AAA through content ID.
Step 205, authentication device sends authentication request to the MCBCS controller of MCBCS controller address indication; The MCBCS controller carries out the professional authentication of using through authentication device to MS.Wherein BS possibly need to transmit the relevant message of authentication;
Step 206, MCBCS controller are returned authenticating result and are given authentication device;
Step 207, authentication device returns to BS with authenticating result; If the authenticating result of refusal service request also needs further the result to be fed back to MS.
Step 208, BS initiates the work of setting up of service channel.
This path setting work also can be initiated by authentication device.
In step 204, " user is in its home network " this hypothesis has bigger limitation, can influence professional the carrying out of MCBCS.For example, if a roaming/mobile subscriber, use be the business in the home network; Perhaps complicated situation more; User in the home network uses the MCBCS that provides in other networks professional; The perhaps business that provides of other (promptly neither home network, neither roaming network) networks of using of roamer, in this case; How realizing the authentication to service-user, is to be difficult to distinguish which MCBCS controller or impossible the realization through MBS content ID only.
Summary of the invention
The technical problem that the present invention will solve provides a kind of method of multicast broadcasting service authentication, and the efficient authentication of the MCBCS registration process that realizes the user is initiatively initiated improves user's business experience.
Because in the Client-initiated MCBCS service log-on process, the user can only provide MBS content ID this parameter through existing standard, can be used for the identification of service provider/MCBCS controller.Certain difficulty can take place in this in concrete network design.As far as MBS content ID, if can belong to which service provider by unique definite MBS content ID, then need apply in the world and distribute, obviously, this is not too reasonably perhaps less feasible.On the one hand, the numerical value of 2 bytes of expression content ID is too little, is not enough to satisfy the use of global scope; On the other hand, also have other solution, also need not carry out the unified distribution in the whole world.Even need in addition to distribute, management is got up and is also bothered very much.To MBS content ID, it is more reasonable to carry out free distribution ratio by different MCBCS service provider/NSP; And different MCBCS service provider/NSP can use identical content ID to indicate different contents fully.
In order to address the above problem, the invention provides a kind of method of multicast broadcasting service authentication, comprising:
Portable terminal is initiated the multicast broadcast service solicitation message to the base station, and the base station is sent the service authentication request message and given authentication device; Said authentication device obtains multicast broadcast service provider sign or multicast broadcast service controller address from said service authentication request message; Perhaps obtain multicast broadcast service provider sign or multicast broadcast service controller address from portable terminal, said authentication device obtains the multicast broadcast service controller address through multicast broadcast service provider sign; Said authentication device is initiated authentication request to the multicast broadcast service controller of said multicast broadcast service controller address indication.
Further, after said multicast broadcast service controller is received said authentication request, carry out authentication and authenticating result is returned to said authentication device.
Further, portable terminal initiates to carry the professional solicitation message of multicast broadcast service content identification to the base station, and the service authentication request message is sent to authentication device in the base station; Authentication device sends the request of multicast broadcast service controller address to portable terminal; Said portable terminal returns the multicast broadcast service controller address to authentication device and replys; And carrying the multicast broadcast service controller address, said authentication device sends authentication request to the multicast broadcast service controller of multicast broadcast service controller address indication.
Further, portable terminal initiates to carry the professional solicitation message of multicast broadcast service content identification to the base station, and the service authentication request message is sent to authentication device in the base station; Authentication device sends multicast broadcast service provider identification request to portable terminal; Said portable terminal returns multicast broadcast service provider sign to authentication device and replys; And carry multicast broadcast service provider sign; From Certificate Authority and accounting server or name server acquisition multicast broadcast service controller address, said authentication device sends authentication request to the multicast broadcast service controller of multicast broadcast service controller address indication to said authentication device through said service provider's sign.
Further, portable terminal sends professional solicitation message to the base station, in this message, carries multicast broadcast service content identification and multicast broadcast service provider sign; Professional application authentication is initiated to authentication device in the base station after receiving said professional solicitation message; Said authentication device identifies from Certificate Authority and accounting server or name server acquisition multicast broadcast service controller address through said service provider, and sends authentication request to the multicast broadcast service controller of multicast broadcast service controller address indication.
Further, said multicast broadcast service provider to be identified at the field figure place that takies in the professional solicitation message be in the following numerical value: 24,16,32.

Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
As shown in Figure 2, after BS receives DSx message, need can use this business to carry out authentication to the user, basic thinking is that authentication device is issued in the unification of relevant authentication demand.Authentication device need confirm by which MCBCS controller this business to be provided according to MBS content ID, and relevant authentication request is sent to this MCBCS controller.
But, in the present DSx message, can not carry than more comprehensive information, and can only pass through MBS content ID, carry out the judgement of MCBCS controller.But, have the following several kinds of situation that possibly do special processing:
1) a plurality of MCBCS controllers have used identical content ID, and which MCBCS controller then needs further information to judge specifically is;
2) in the content ID that a plurality of MCBCS controllers provide, if do not find occurrence; Abandon or go further to seek the MCBCS controller in the broad range more;
3) through comparing, the content that a plurality of MCBCS controllers provide has only a content ID to match.
These possibilities cause the processing procedure more complicated, can cause bigger processing time-delay.Because it is who provides that the user knows this business, so in the scheme among the present invention, before carrying out authentication, authentication device and user carry out once mutual, directly to obtain MCBCS controller address or service provider ID.If directly obtain the MCBCS controller address, then can confirm unique MCBCS controller from the user; If obtain service provider ID,, thereby confirm unique MCBCS controller then again from its corresponding MCBCS controller address of AAA/DNS (domain name system) server inquiry from the user.And to the business tine in signatory operator not, the MCBCS controller information that also can provide through the user is dynamically registered with business work is provided, certainly this need and different business provider between have dynamic service to provide agreement and scheme.Like this, can guarantee the suit property that the MCBCS business is carried out.
Embodiment one:
As shown in Figure 3, the multicast/broadcast service authentication method specifically may further comprise the steps:
Step 302, MS carries out business application/activation through sending DSx message to BS, in this message, carries the content ID (MBS content ID) of multicast broadcast service.Be that the user carries out the work of setting up of service channel through DSx message, initiatively initiate the professional application of its interested MCBCS;
Step 303, BS initiates professional application authentication to its authentication device after receiving the professional solicitation message of DSx;
Step 304.1, authentication device sends MCBCS controller address request message to the user;
Step 304.2, the user returns MCBCS controller address response message to authentication device; Wherein carry the MCBCS controller address;
Step 305, authentication device are directly sent authentication request to the MCBCS controller of MCBCS controller address indication; The MCBCS controller carries out the professional authentication of using through authentication device to MS.Wherein BS possibly need to transmit the relevant message of authentication;
Step 306, MCBCS controller are returned authenticating result and are given authentication device;
Step 307, authentication device returns to BS with authenticating result; If the authenticating result of refusal service request also needs further the result to be fed back to MS.
Step 308, BS initiates the work of setting up of service channel.
Embodiment two:
As shown in Figure 4, step 401 to 403 with step 301 shown in Figure 3 to 303 identical;
Step 404.1, authentication device sends MCBCS service provider ID request message to the user;
Step 404.2, the user returns service provider ID response message to authentication device; Wherein carry service provider ID;
Step 404.3, authentication device and AAA/DNS obtain the MCBCS controller address through said service provider ID from AAA/DNS alternately;
In most cases, corresponding MCBCS controller address of service provider ID.But do not get rid of the situation that might have one-to-many.
Step 405 to step 408 is identical with step 305 to step 308 shown in Figure 3.
Case study on implementation three:
Can know through Fig. 2; The reason of the complicacy of scheme is that the information that MS carries in the professional solicitation message of the DSx that BS sends is insufficient, causes a large amount of processing and time-delay; And these information are to obtain very expediently; Can make it can carry MCBCS service provider's information, thereby support to realize access authentication fast through the parameter of the DSx message in the expansion IEEE802.16 series standard.
The concrete parameter that increases can be service provider's a information (like service provider ID).Can be used to define service provider's information through a field of 24 (or fields of 16 or 32 or other figure place).The concrete parameter that increases can also be the MCBCS controller information, like the IP address of controller.
As shown in Figure 5, the multicast/broadcast service authentication method may further comprise the steps:
Step 501, the user is through service statement, and perhaps other approach obtain relevant business information;
Step 502, MS initiates professional foundation to BS, sends the professional solicitation message of DSx, in this message, carries content ID and the MCBCS service provider ID or the MCBCS controller address of multicast broadcast service; This controller address can be 32 or 128, corresponds respectively to the applicable cases of IPv4 (Internet Protocolversion 4, procotol the 4th edition)/IPv6 (Internet Protocol version 6, procotol the 6th edition).
Step 503, BS initiates professional application authentication to authentication device after receiving the professional solicitation message of DSx;
Step 504, authentication device obtains MCBCS controller address information according to service provider ID from AAA/DNS; If what carry among the DSx is MCBCS controller address information, then this step can be omitted.
Step 505 to step 508 is identical with step 305 to step 308 shown in Figure 3.
In sum, adopt the inventive method, the efficient authentication of the MCBCS registration process that can realize the user is initiatively initiated, thus improve user's business experience.
The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art are when making various corresponding changes and distortion according to the present invention, and these change and be out of shape the protection range that all should belong to the appended claim of the present invention accordingly.
