Abstract
Methods and systems for reestablishing a mobile device RRC connection based on eNodeB messaging. An RRC (Radio Resource Control) connection reestablishment request for the mobile device is received at a first eNodeB (Evolved NodeB). It is determined that the RRC connection reestablishment request requires mobile device context data that is unavailable at the first eNodeB. The first eNodeB communicates an initial mobile device service request message to an MME (Mobility Management Entity) based on a determination that the RRC connection request requires the mobile device context data that is unavailable at the first eNodeB. Upon communicating the initial mobile device service request message, the first eNodeB receives the mobile device context data in order to reestablish the mobile device RRC connection.
