Conserving resources of a next generation satellite
A system and method for reducing usage of satellite channelizers including dividing a frequency spectrum into sub-bands; providing a satellite channelizer for each of the sub-bands, where each of the sub-bands may include channels; multiplexing service channels into the channels of one of the sub-bands, where the service channels convey data for a plurality of MSSs. A system and method for obtaining high throughput on a satellite network. A system and method for providing a Fair Access Policy (FAP) in a 4G system.
1. A method for reducing usage of satellite channelizers, the method comprising:
sharing a satellite channelizer offering channels in a frequency band with a first gateway and a second gateway; and
combining, prior to a channelizer, a channel of the first gateway and a channel of the second gateway to form the channels of the satellite channelizer,
wherein the first gateway operates at one of the channels and the second gateway operates at a remaining one of the channels,
wherein the one of the channels conveys a 4G service and the remaining one of the channels conveys a 2G or “GMR-1 Voice and IP Data ETSI 2.2.z or GMR-1 Voice and IP Data ETSI 3.3)” (2.5G) service;
determining, with a usage monitoring control, that a spending limit has been reached for a User Equipment (UE) on a 4G service;
downgrading, for the first channel, an Aggregate Bit Rate (AMBR) for Access Point Names (APNs) associated with the UE;
calculating a new UE-AMBR and a new Quality Class Identifier (QCI) for the UE based on the AMBRs of the APNs; and
setting the new QCI for satellite bearers associated with the UE on a satellite air interface.
2. The method of claim 1 , wherein the channel of the first gateway comprises a commercial BCCH (Broadcast Control Channel) and the channel of the second gateway comprises a government BCCH.
3. The method of claim 2 , wherein the channel of the first gateway comprises a voice channel.
4. The method of claim 1 , wherein the channel of the first gateway comprises a commercial BCCH and a voice channel.
5. The method of claim 1 , wherein one of the channels comprises a BCCH for multiple beams.
6. The method of claim 1 , wherein at least one of the channels comprises a Common Control Channel comprising a GMR-1 Voice ETSI Standard (2G) BCCH and a GMR-1 4G (4G) BCCH.
7. The method of claim 1 , further comprising:
generating, from a MAC/RLC layer, a data stream comprising packets for an aggregated channel comprising a plurality of channels;
splitting the data stream into sub-data streams; and
transmitting each of the sub-data streams via one or more of the plurality of channels.
8. The method of claim 7 , wherein the aggregated channel is transmitted from a Next Generation Service Gateway (NGSG), the aggregated channel conveys the packets for a plurality of Mobile Satellite Services (MSSs), and a bandwidth of the aggregated channel is allocated to the plurality of MSSs using Time Division Multiple Access (TDMA).
9. The method of claim 7 , wherein the aggregated channel is transmitted from a User Equipment (UE), the aggregated channel conveys the packets for a plurality of Mobile Satellite Services (MSSs), and a bandwidth of the aggregated channel is allocated to the plurality of MSSs using Time Division Multiple Access (TDMA).
10. The method of claim 7 , further comprising:
receiving each of the sub-data streams; and
combining the sub-data streams into an output data stream.
11. The method of claim 10 , wherein the combining restores an order of the transmitting in the output data stream.
12. The method of claim 11 , wherein the aggregated channel comprises contiguous carriers.
13. The method of claim 7 , wherein the aggregated channel comprises non-contiguous carriers.
14. The method of claim 7 , further comprising managing the plurality of channels in the aggregated channel.
15. The method of claim 1 , wherein the downgrading is performed by a Packet Data Network Gateway (PGW) of a Core Network (CN).
16. The method of claim 1 , wherein the calculating comprises mapping the new QCI based on the new UE-AMBR.
17. The method of claim 1 , wherein the setting is performed by a Next Generation Service Gateway (NGSG) comprising a relay between a satellite AS/NAS stack and a terrestrial 4G stack.
