METHODS AND APPARATUS TO SIGNAL ACCESS-STRATUM CAPABILITIES OF MOBILE STATIONS FOR DATA TRANSFER SESSIONS

摘要

Example methods and apparatus to signal access-stratum capabilities of mobile stations for data transfer sessions are disclosed. In accordance with a disclosed example method a capabilities structure is selected from a group of capabilities structures. The capabilities structure is indicative of a set of radio access capabilities of the mobile station for a data transfer session between the mobile station and a network. A structural format of the message is formatted based on the selected capabilities structure to include radio access capabilities information of the selected capabilities structure. A code is included in the message to indicate the presence of the selected capabilities structure in the message. The message is sent from the mobile station to the network.
