Section: 9.3.3.2 Bearer capability 1 and bearer capability 2
Content: The bearer capability 1 information element shall be included if the network has to specify at least one of the negotiable parameters described in 3GPP TS 27.001[ General on Terminal Adaptation Functions (TAF) for Mobile Stations (MS) ]  [36], or if the bearer capability 1 information element received in the SETUP message included the "fixed network user rate" parameter. When the bearer capability 1 information element is followed by the bearer capability 2 IE in the SETUP, the above rule applies to both bearer capability 1 IE and bearer capability 2 IE. Except those cases identified in 3GPP TS 27.001[ General on Terminal Adaptation Functions (TAF) for Mobile Stations (MS) ]  [36], if either bearer capability needs to be included, both shall be included.
