Broadcast Multicast Service


Broadcast Multicast Service
 
 
This chapter provides information on Broadcast Multicast Service (BCMCS) functionality. The product Administration Guides provide examples and procedures for configuration of basic services on the system. It is recommended that you select the configuration example that best meets your service model, and configure the required elements for that model, as described in the respective product Administration Guide, before using the procedures in this chapter.
Important: The features described in this chapter are only available if you have purchased and installed a feature license for Broadcast & Multicast Services.
This chapter contains the following sections:
 
 
Overview
BCMCS eliminates unnecessary replication of data on CDMA2000 wireless networks by transmitting a single stream of data to multiple users. By delivering a single, unidirectional data stream to many subscribers, BCMCS makes more efficient use of wireless network resources than traditional point to point connections.
BCMCS functionality on the system is provided by an existing PDSN service and is enabled by a valid Broadcast & Multicast Services license. In the absence of a valid license, the system functions as a standard unicast PDSN. When a PDSN is functioning in a BCMCS environment, it is designated as a Broadcast Serving Node (BSN). The main features supported by the Broadcast & Multicast Services license are:
 
 
Licensing
To enable BCMCS on the system, you must install the Broadcast & Multicast Services license. For more information on installing licenses, refer to Software Maintenance Operations in the System Administration Guide.
 
Configuring BCMCS
To configure the system for BCMCS:
Step 1
Step 2
Step 3
Step 4
Save your configuration as described in the Verifying and Saving Your Configuration chapter.
Important: Commands used in the configuration examples in this section provide base functionality to the extent that the most common or likely commands and/or keyword options are presented. In many cases, other optional commands and/or keyword options are available. Refer to the Command Line Interface Reference for complete information regarding all commands.
 
BCMCS Group Configuration
Use the following example to set the BCMCS group user name and password for RADIUS access:
configure
  context <context_name>
        pdsn-service <pdsn_service_name>
        bcmcs grpusrname <group_name>
        bcmcs grppasswd <group_password>
        end
 
RADIUS Server Configuration
You must create a multicast group profile on your RADIUS server to achieve BCMCS functionality. The group name and password must be the same as configured in BCMCS Group Configuration section.
For information about the supported BCMCS attributes, refer to the AAA Interface Administration and Reference.
