Introduction Broadcast Teleservice Transport is provided by the Broadcast Air-interface Transport Service (BATS). BATS operates between a Teleservice Server (TS) and mobile stations using both TIAEIA-136 and TIAEIA-41 based protocol stacks along with a BMI based relay function as shown in Figure 1. BATS is a general purpose broadcast transport mechanism that can be used by existing teleservices (e.g.@ CMT@ OPTS@ GUTS@ and carrier-specific teleservices) as well as other future teleservices/applications requiring broadcast transport support.
