Abstract

A method for receiving a service in a mobile terminal from a network in a wireless communication system, the method comprising establishing a first radio bearer and receiving a first service associated with the first radio bearer and receiving second radio bearer setup information from the network to establish a second radio bearer for receiving a second service associated with the second radio bearer. The mobile terminal prioritizes between the first service associated with the first radio bearer and the second service associated with the second radio bearer and determines whether the mobile terminal is able to receive a higher prioritized service if the second radio bearer is established. Furthermore, the mobile terminal retains the higher prioritized service.
