Method and system facilitating communication between user equipment and external network

A communication system having a first network with multiple UEs, a core network, and a gateway device, and a second network, wherein the gateway device is capable of facilitating a communication between a first UE and the second network, and the gateway device having a first network interface and a second network interface is adapted to:

• learn UE-related parameters of the UEs including operating modes, identity information, and connection status by selectively transmitting a first request to the core network via the first network interface thereof, or transmitting a second request to the UEs via the second network interface thereof and receiving the UE-related parameters in a first set of predetermined messages from the core network, or receiving the UE-related parameters in a second set of predetermined messages from the UEs, respectively;
• transmit the UE-related parameters via the second network interface thereof to the UEs in terms of a third set of predetermined messages;
• and
• coordinate with the UEs to allow for the first UE to facilitate the communication with the second network through the second UE via the core network, depending on interface operating status of the second UE and a spatial relationship between the first UE and the second UE.

A non-transitory computer readable medium comprising a set of computer instructions when executed by a processing unit of a gateway device for facilitating the communication between a first network and a second network, wherein the first network having the gateway device further comprises UEs including a first UE and a second UE and a core network, the computer instructions when executed by the processing unit causing the processing unit to:

• enable the gateway device to learn UE-related parameters of the UEs including operating modes, identity information, and connection status by selectively transmitting a first request to the core network or transmitting a second request to the UEs;
• enable the gateway device to receive the UE-related parameters from the core network in terms of a first set of predetermined messages or from the UEs in terms of a second set of predetermined messages, and broadcast the UE-related parameters to the UEs in terms of a third set of predetermined messages;
• and
• enable the gateway device to coordinate with the UEs allowing for the first UE to facilitate the communication with the second network through the second UE via the core network, depending on an interface operating status of the second UE and a spatial relationship between the first UE and the second UE.
