Abstract
Methods, systems, and computer readable media are presented for retrieving security keys in gateways. In one example embodiment, a method is presented. The method of retrieving security keys from a User Equipment (UE) in gateways includes retrieving, by a HetNet Gateway (HNG) as the HNG virtualizes an eNodeB towards n Mobility Management Entity (MME) through a first message and a second message exchange, a fresh Next Hop, Next Hop Chaining Count {NH, NCC} pair from the MME; and mocking, by the HNG, an X2 handover towards the MME by sending a third message with required Information Elements filled when a fourth message from the eNodeB reaches the HNG.
Claims18
A method of retrieving security keys from a User Equipment (UE) in gateways, comprising:
- retrieving, by a HetNet Gateway (HNG) as the HNG virtualizes an eNodeB towards a Mobility Management Entity (MME) through a first message and a second message exchange, a fresh Next Hop, Next Hop Chaining Count {NH, NCC} pair from the MME;
- and
- mocking, by the HNG, an X2 handover towards the MME by sending a third message with required Information Elements filled when a fourth message from the eNodeB reaches the HNG.
A system for retrieving security keys in gateways, comprising:
- a HetNet Gateway (HNG), wherein the HNG retrieves, as the HNG virtualizes an eNodeB towards a Mobility Management Entity (MME) through a first message and a second message exchange, a fresh Next Hop, Next Hop Chaining Count {NH, NCC} pair from the MME;
- and
- mocks an X2 handover towards the MME by sending a third message with required Information Elements filled when a fourth message from the eNodeB reaches the HNG.
A non-transitory computer-readable medium containing instructions for retrieving security keys from a User Equipment (UE) in gateways, which, when executed, cause a network node to perform steps comprising:
- retrieving, by a HetNet Gateway (HNG) as the HNG virtualizes an eNodeB towards a Mobility Management Entity (MME) through a first message and a second message exchange, a fresh Next Hop, Next Hop Chaining Count {NH, NCC} pair from the MME;
- and
- mocking, by the HNG, an X2 handover towards the MME by sending a third message with required Information Elements filled when a fourth message from the eNodeB reaches the HNG.
