Embodiment 1
[0054] Such as image 3 As shown, the multicast / broadcast service authentication method specifically includes the following steps:
[0055] Step 301, the user obtains MCBCS service information through service statement or other means;
[0056] In step 302, the MS sends a DSx message to the BS for service application / activation, and the message carries the content ID of the multicast broadcast service (MBS content ID). That is, users establish service channels through DSx messages, and actively initiate applications for MCBCS services they are interested in;
[0057] Step 303, after receiving the DSx service application message, the BS initiates service application authentication to its authenticator;
[0058] Step 304.1, the authenticator sends an MCBCS controller address request message to the user;
[0059] Step 304.2, the user returns the MCBCS controller address response message to the authenticator; it carries the MCBCS controller address;
[0060] In step 305, the au...
Embodiment 2
[0065] Such as Figure 4 As shown, steps 401 to 403 are related to image 3 Steps 301 to 303 shown are the same;
[0066] Step 404.1, the authenticator sends an MCBCS service provider ID request message to the user;
[0067] Step 404.2, the user returns a service provider ID response message to the authenticator; the message carries the service provider ID;
[0068] Step 404.3, the authenticator interacts with the AAA / DNS to obtain the MCBCS controller address from the AAA / DNS through the service provider ID;
[0069] In most cases, one service provider ID corresponds to one MCBCS controller address. However, it is not ruled out that there may be a one-to-many situation.
[0070] Step 405 to step 408, with image 3 The steps 305 to 308 shown are the same.
Embodiment example 3
[0072] pass figure 2 It can be seen that the reason for the complexity of the solution is that the information carried in the DSx service application message sent by the MS to the BS is insufficient, resulting in a large amount of processing and delay, and this information can be obtained very conveniently, and can be obtained by extending the IEEE802.16 series The parameters of the DSx message in the standard enable it to carry the information of the MCBCS service provider, thus supporting fast access authentication.
[0073] The specific added parameter may be service provider information (such as service provider ID). A field of 24 bits (or 16 bits, or 32 bits, or a field of other bits) can be used to define the information of the service provider. The specific added parameter may also be MCBCS controller information, such as the IP address of the controller.
[0074] Such as Figure 5 As shown, the multicast / broadcast service authentication method includes the followin...
