A wireless communication system may include a serving gateway (SGW) operably coupled to a packet data network gateway (PGW) to setup a session responsive to a request from a terminal to establish the session between the terminal and the PGW. The system may further include deferred data bearers (DDBs), data volumes, contacts, data volume descriptions associated with the data volumes, an application data interface configured to receive the plurality of data volume descriptions and associated data volumes from applications on the terminal, and a deferred bearer agent (DBA) that associates the incoming data volume descriptions and data volumes received from the application data interface with the DDBs based on metrics and transmits data stored in deferred data bearers over contacts established on the terminal for communication to the PGW.

Space-based long term evolution (LTE) communications architecture

A wireless communication system may include an SGW operably coupled to a PGW to setup a session responsive to a request from a terminal to establish the session between the terminal and the PGW. The system further includes an MME configured to authenticate the terminal and provide bearer management in response to the request. The MME is configured to provide bearer information to the SGW. The system also includes base stations operably coupled to the SGW via a data plane connection and operably coupled to the MME via a control plane connection. The base stations are configured to handover connection to the terminal between the base stations in response to movement of the terminal between coverage areas of the base stations. The MME is configured to assign a deferred bearer in response to a determination that suitability criteria for establishing an active bearer are not met, the deferred bearer reserving a future data bearer and signaling the terminal to store data locally until the future data bearer is established.
