A method comprising: receiving a radio access bearer setup request, at a remote terminal of a satellite network, to admit a new session from an external network over the satellite network; determining whether a requested guaranteed bit rate for the new session is available from the remote terminal; and when the requested guaranteed bit rate is available: forwarding the request to a gateway of the satellite network, and admitting the new session, over the satellite network, to the external network using the requested guaranteed bit rate;the method being characterized in that when the requested guaranteed bit rate is not available: determining whether the available guaranteed bit rate from the remote terminal is greater than or equal to 50% of the requested guaranteed bit rate; and when the available guaranteed bit rate from the remote terminal is greater than or equal to 50% of the requested guaranteed bit rate: admitting the new session using a quasi-guaranteed bit rate; and notifying the external network of the new session status, wherein the quasi-guaranteed bit rate is defined as a bit rate including: a portion of the requested guaranteed bit rate allocated from the remote terminal's guaranteed bit rate, and a remainder of the requested guaranteed bit rate allocated from the remote terminal's maximum available bit rate using best effort delivery completion. receiving a radio access bearer setup request, at a remote terminal of a satellite network, to admit a new session from an external network over the satellite network; determining whether a requested guaranteed bit rate for the new session is available from the remote terminal; and when the requested guaranteed bit rate is available: forwarding the request to a gateway of the satellite network, and admitting the new session, over the satellite network, to the external network using the requested guaranteed bit rate;the method being characterized in that forwarding the request to a gateway of the satellite network, and admitting the new session, over the satellite network, to the external network using the requested guaranteed bit rate;the method being characterized in that when the requested guaranteed bit rate is not available: determining whether the available guaranteed bit rate from the remote terminal is greater than or equal to 50% of the requested guaranteed bit rate; and when the available guaranteed bit rate from the remote terminal is greater than or equal to 50% of the requested guaranteed bit rate: admitting the new session using a quasi-guaranteed bit rate; and notifying the external network of the new session status, wherein the quasi-guaranteed bit rate is defined as a bit rate including: a portion of the requested guaranteed bit rate allocated from the remote terminal's guaranteed bit rate, and a remainder of the requested guaranteed bit rate allocated from the remote terminal's maximum available bit rate using best effort delivery completion. determining whether the available guaranteed bit rate from the remote terminal is greater than or equal to 50% of the requested guaranteed bit rate; and when the available guaranteed bit rate from the remote terminal is greater than or equal to 50% of the requested guaranteed bit rate: admitting the new session using a quasi-guaranteed bit rate; and notifying the external network of the new session status, wherein the quasi-guaranteed bit rate is defined as a bit rate including: a portion of the requested guaranteed bit rate allocated from the remote terminal's guaranteed bit rate, and a remainder of the requested guaranteed bit rate allocated from the remote terminal's maximum available bit rate using best effort delivery completion. admitting the new session using a quasi-guaranteed bit rate; and notifying the external network of the new session status, wherein the quasi-guaranteed bit rate is defined as a bit rate including: a portion of the requested guaranteed bit rate allocated from the remote terminal's guaranteed bit rate, and a remainder of the requested guaranteed bit rate allocated from the remote terminal's maximum available bit rate using best effort delivery completion. a portion of the requested guaranteed bit rate allocated from the remote terminal's guaranteed bit rate, and a remainder of the requested guaranteed bit rate allocated from the remote terminal's maximum available bit rate using best effort delivery completion.
