Abstract
Some demonstrative embodiments include devices, systems and/or methods of establishing a connection between a cellular node and a core network. For example, a first Evolved Node B (eNB) may include a cellular transceiver to communicate with a User Equipment (UE); an X2 interface to communicate with at least one second eNB; and a controller to send to the second eNB a first message including a core network node discovery request, to receive from the second eNB a second message including a core network node identifier, and to establish an S1 connection between the first eNB and a core network using the core network node identifier.
Claims25
A first Evolved Node B (eNB) comprising:
- a cellular transceiver to communicate with a User Equipment (UE);
- an X2 interface to communicate with at least one second eNB;
- and
- a controller to send to the second eNB a first message including a core network node discovery request, to receive from the second eNB a second message including a core network node identifier, and to establish an S1 connection between said first eNB and a core network using said core network node identifier.
A first Evolved Node B (eNB) comprising:
- a core network interface to communicate with a core network;
- an X2 interface to communicate with at least one second eNB;
- and
- a controller to receive from the second eNB a core network node discovery request, and to send to the second eNB a response including a core network node identifier representing a core network node.
A method to be performed at a first Evolved Node B (eNB), the method comprising:
- establishing an S1 connection between a second eNB and a core network node of a core network via said first eNB;
- and
- communicating an X2 Application Protocol (X2AP) message between said first eNB and said second eNB, the X2AP message including a core network node identifier of said core network node and encapsulating an S1AP message of said S1 connection between said second eNB and said core network node.
A product including one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement a method at a first Evolved Node B (eNB), the method comprising:
- sending to a second eNB a first message including a core network node discovery request;
- receiving from the second eNB a second message including a core network node identifier;
- and
- establishing an S1 connection between said first eNB and a core network using said core network node identifier.
