Abstract
A method and apparatus are provided for assigning radio network control in a mobile communications system that offers two or more types of bearer services. The mobile network broadcasts an initial control message that orders certain mobile terminals to suspend use of their normal terminal-based radio network control decisions and to accept radio network control orders from the land mobile network. A subsequent control message can order the resumed use of normal terminal-based radio network control decisions. Consequently the mobile network can use virtually the same control logic for all of the mobile terminals that it serves regardless of the type bearer service being carried. As a result radio signal interference between mobile terminals carrying the different bearer services can be minimized.
