Abstract
Systems and methods for enabling data and voice communications via a satellite network are disclosed herein. In an embodiment, a method of enabling data and voice communications for a user terminal includes establishing a local connection between the user terminal and a first core network operated by a first network provider, routing data communications received by the first core network from the user terminal to a satellite terminal operated by the first network provider for further transmission via a satellite, and routing voice communications received by the first core network from the user terminal to a second core network operated by a second network provider.

A method of enabling data and voice communications for a user terminal subscribing to a first core network having a first packet data network gateway (PGW) and a home subscriber server (HSS) and being operated by a first network provider, the method comprising:
- establishing a local connection between the user terminal and a second core network operated by a second network provider for both data communications and voice communications to be transmitted between the user terminal and the second core network, the second core network including a serving gateway (SGW), a second packet data network gateway (PGW) and a mobility management entity (MME);
- communicating between the MME of the second core network and the HSS of the first core network regarding the user terminal;
- thereafter establishing a local breakout enabling the data communications to be transmitted to and from the user terminal via the second core network;
- thereafter establishing a roaming connection enabling the voice communications to be transmitted to and from the user terminal via both the first core network and the second core network;
- thereafter using the local breakout to route the data communications to and from the user terminal through the SGW and the second PGW of the second core network and a satellite terminal operated by the second network provider that transmits via a satellite;
- and
- thereafter using the roaming connection to route the voice communications to and from the user terminal through the first PGW of the first core network and the SGW of the second core network.
A network configured to enable data and voice communications for a user terminal subscribing to a first core network having a first packet data network gateway (PGW) and a home subscriber server (HSS) and being operated by a first network provider, the network comprising:
- a satellite network operated by a second network operator, the satellite network including a satellite terminal configured to communicate with a system gateway via a satellite;
- and
- a second core network operated by the second network operator, the second core network including a serving gateway (SGW), a second packet data network gateway (PGW) and a mobility management entity (MME),
- the second core network configured to transmit data communications and voice communications to and from the user terminal, the second core network further configured to (i) cause communication between the MME and the HSS of the first core network regarding the user terminal;
- (ii) thereafter establish a local breakout enabling the data communications to be transmitted to and from the user terminal by the second core network;
- (iii) thereafter establish a roaming connection enabling the voice communications to be transmitted to and from the user terminal via both the first core network and the second core network;
- (iv) thereafter use the local breakout to route the data communications to and from the user terminal through the SGW, the second PGW and the satellite network, and (v) thereafter use the roaming connection to route the voice communications to and from the user terminal through the SGW and the first PGW of the first core network.
A core network comprising:
- a serving gateway (SGW) configured to route data communications and voice communications to or from a user terminal;
- a first packet data network gateway (PGW) in communication with a local satellite terminal operated by a first network provider;
- and
- a mobility management entity (MME) configured to communicate with a home subscriber server (HSS) operated by a second network operator regarding the user terminal,
- the SGW configured to (i) route the data communications between the user terminal and the first PGW, and (ii) route the voice communications between the user terminal and a second PGW of another core network operated by the second network operator, and
- the SGW configured to route the data communications to the first PGW for communication to the local satellite terminal after the MME has communicated with the HSS regarding the user terminal.
A core network comprising:
- a serving gateway (SGW) configured to route data communications and voice communications to or from a user terminal;
- a first packet data network gateway (PGW) in communication with a local satellite terminal operated by a first network provider;
- and
- a first policy and charging rules function (PCRF) configured to communicate with a second PCRF operated by a second network operator regarding the user terminal,
- the SGW configured to (i) route the data communications between the user terminal and the first PGW, and (ii) route the voice communications between the user terminal and a second PGW of another core network operated by the second network operator,
- the SGW configured to route the data communications to the first PGW for communication to the local satellite terminal after the first PCRF has communicated with the second PCRF regarding the user terminal.
